Single-punch tablet press machine die instructions
1. die installation:
(1) Installation of the lower punch
Loosen the lower punch fixing screw, rotate the large belt wheel to make the lower punch mandrel to the highest position, insert the lower punch into the hole of the lower punch mandrel (pay attention to make the lower punch). Insert the downstroke into the hole of the downstroke core rod (pay attention to make the notch of the downstroke rod beveled against the downstroke fastening screw, and insert it to the end) and finally tighten the downstroke fixing screw.
(2) Installation of the upper punch
Loosen the upper punch fastening nut, insert the upper punch into the hole of the upper punch mandrel, to the end, and tighten the upper punch fastening nut.
(3) Installation of the center die
Screw the center die fixing screw, put the center die into the hole of the center die plate, and at the same time, make the lower punch enter into the hole of the center die, and press it to the end, and then tighten the fixing screw of the center die. When you put the center mold, you should pay attention to put the center mold flat, so as not to be skewed into the hole when stuck, damage to the hole wall.
(4) rotate the big pulley by hand, make the upper punch slowly descend into the hole of the middle mold, observe whether there is any collision or friction phenomenon, if there is collision or friction, then loosen the middle mold plate fixing screws (two), adjust the position of the middle mold plate fixing, make the upper punch into the hole of the middle mold, and then tighten the middle mold plate fixing screw, and so on until the upper punch enters into the hole of the middle mold, there is no collision or friction before the installation of the qualified.

2. Adjustment of the piece
Turn the big pulley to make the lower punch to the highest position, observe whether the lower punch surface and the plane of the middle mold (or high or low will affect the piece) if not, then loosen the butterfly screws, loosen the gear pressure plate and turn the upper adjusting gear, so that the lower punch surface and the plane of the middle mold, and then press the pressure plate on, tighten the butterfly screws.
To this point, turn the big pulley by hand, empty run more than ten turns, if the machine is running normally, you can add material test pressure, the next step in the adjustment.
3. Adjustment of filling depth (i.e., adjustment of tablet weight)
Screw the butterfly screw and loosen the gear pressure plate. Turn the lower adjusting gear to the left so that the lower punch core lever rise, the filling depth is reduced (the weight of tablets to reduce), and vice versa the filling depth increases (the weight of tablets to increase). After adjusting, press the gear pressure plate on and tighten the butterfly screw.
4. Pressure adjustment (that is, the adjustment of tablet hardness)
Screw the knurled screw, downward adjustment of the eccentric wheel copper sleeve, the pressure to increase the hardness of the tablets pressed out to increase; on the contrary, upward adjustment of the pressure to reduce the hardness of tablets to reduce the adjustment of the knurled screw, the eccentric wheel copper sleeve can be tightened lock.

So far, the adjustment of the mold is basically complete, and then start the motor test pressure of more than ten tablets, check the weight, hardness and surface finish and other qualities such as qualified, you can feed the production. In the production process must still check the quality of tablets at any time, timely adjustment.
5.5.disassembly of the mold
(1) disassembly of the upper punch
Screwing the upper punch fastening nut, the upper punch can be pulled out of the rod, if the fit is tight, can be used to clamp the upper punch rod will be pulled out, but pay attention to not damage the punching head of the edge of the shuttle.
(2) Disassemble the middle mold
Screw the middle mold fixing screw. Unscrew the lower punch fixing screw, loosen the butterfly screw, and loosen the gear pressure plate. Rotate the adjusting gear so that the lower punch core rod up about ten millimeters, gently turn the large pulley, so that the lower punch core rod will be part of the top of the mold, the hand will be taken out of the middle mold, if the middle mold in the hole with the tight, do not force to rotate the handwheel to hard top, in order to avoid damage to the machine parts. In this case, you have to remove the table plate of the middle mold and then take out the middle mold.
(3) dismantle the lower punch
First, we have screwed down the lower punch fixing screw, and then turn the handwheel to make the lower punch core lever to the highest position, you can use your hands to pull out the upper punch lever. If the fit is tight, it can be clamped out with pliers (be careful not to damage the edge of the punch).
(4) after the disassembly of the mold must be turned to adjust the gear, so that the lower punch core bar back down about 10 mm, turn the handwheel so that the lower punch core bar to the highest position, the top is not higher than the bottom of the mold plate with can (this step should not be ignored, so as not to use again to avoid the occurrence of the lower punch core bar and the top of the mold collision of the accident). Finally, the lower punch fixing screws are still screwed on.
Fifth, the main components of the single-punch tablet press disassembly and installation
1. middle mold plate
Disassembly: pull out the powder blocking plate, remove the hopper, spin out the feeder set screws, spin down the feeder fixing screws and springs, remove the feeder, spin down the middle mold plate fixing screws and spring washers, you can take down the middle mold plate.
Installation: Refer to the reverse order above. Be careful to align the feeder when tightening the screws. To avoid damage to the wire hole of the feeder.
2. Upper Punching Mandrel:
Disassembly: Loosen the upper punching mandrel small shaft fastening screw, take out the small shaft, and then loosen the upper punching mandrel fastening screw. Remove the main shaft first (refer to 5 main shaft) and pull it out. When installing, the upper punching core bar must be installed first before installing the main shaft and so on.
3. Lower Punching Mandrel:

Disassembly: Screw down the lower punching fixing screws, butterfly screws, and the gear pressure plate to rotate the adjusting gear, so as to lower the lower punching mandrel and take it out from under the bottom hole of the machine body. Installation: Refer to the reverse order above.
4. Big pulley, pinion and overshaft
Disassembly: Put down the triangle belt, turn down the left and right screws of the overshaft and the pressure plate, tap the big pulley with a wooden hammer to remove it, pull out the overshaft, and then tap the pinion with a wooden hammer to remove it.
Installation: refer to the reverse order above.
5. Spindle:
Disassembly: disassembly of the spindle should be carried out by two people. First remove the shield, then remove the large gear, loosen the lifting cam and eccentric wheel, fastening screws. Remove the toggle cam, and then use a wooden hammer and copper rod to knock the shaft end (be careful not to damage the screw holes at the end of the shaft), and at the same time hold the other end of the shaft firmly and hold the eccentric wheel shell and lifting cam, and slowly dismantle the spindle. (Note: Do not lose the lifting roller and pulling roller.)
Installation: Refer to the above reverse order.
Six, single punch tablet press machine lubrication and maintenance
1. the friction surface lubrication is to ensure the normal operation of the machine and extend the service life of the important links, especially the main moving parts in the absence of oil in the case of dry running will be quickly damaged and can not be used, therefore, the tablet press machine in the use of the oil cups must be all the oil holes and friction plus lubricating oil, and running to make the friction surface full of oil film, the friction surface, the friction surface of the oil film. Therefore, before use, all oil cups, holes and friction surfaces must be filled with lubricating oil, and the machine should be run empty so that the friction surfaces will be covered with oil film. In the future, the machine should be refueled on time every shift, but the refueling should not be too much, so as not to affect the cleanliness of the overflow and contamination of the tablets. Each refueling parts and refueling times are shown in the following table:
Refueling parts and refueling times table
Serial No. Refueling parts added lubricant refueling times per shift
1 spindle hole oil cups (2) grease 2-3 times
2 eccentric wheel shell oil hole (pressure adjustment screw hole) oil 2-3 times
3 over the axle wheel axle oil cups 2 (the back of the body) grease 2-3 times
3 over the bridge wheel axle oil cups (rear) Grease 2-3 times
4 Lifting cam groove Grease Check the groove surface every shift to remove dirt and add grease
5 Filling cam groove Grease Check every shift and add oil as necessary
6 Gear tooth surface Grease Check every shift and add oil as necessary
7 Upper punching mandrel oil hole Grease 1 time
8 Oscillating pivot point of lever Grease 1 time
9 Upper punching mandrel hole (screw hole for pressure adjustment) Grease 1 time
9 Upper punching mandrel hole (screw hole for pressure adjustment) Grease 1 time
10 Upper punching mandrel hole (screw hole for pressure adjustment)
9 The surface of the upper punch rod grease 2 times
10 The surface of the lift lever grease 2 times

2. Every shift before the screws must be checked for looseness, and in the process of the work should be often pay attention to the check, such as loosening, immediately tighten to avoid failure. The main parts are:
(1) the upper punch fastening nut, the middle mold set screws, the lower punch set screws;
(2) the upper punch mandrel small shaft set screws;
(3) lifting fork locking nut (2) butterfly screws;
(4) in the mold plate set screws;
(5) the hopper set screw;
(6) extractor rod coupling screws. (6) Draw bar coupling screws.
3. Before each shift and after each shift must be hand-cranked test pressure a few pieces, no problem before turning on the electric pressure piece.
4. In the process of pressing tablets must often check the quality of the die, such as found to have missing edges, cracks, deformation of serious damage, should be replaced in a timely manner, in order to avoid malfunction and damage to the machine and affect the quality of tablets.
5. The remaining powder should be taken out after use every day, and the machine should be wiped clean. If the suspension time is longer, it is necessary to remove the mold, the machine friction surface, the working surface clean, coated with antirust oil, cover the dust coat; mold should be cleaned and immersed in oil to keep the desktop publishing system.
6. Regular inspection of the machine 2 times a month.
Seven, single-punch tablet press machine precautions
1. First use should be carefully read the manual against the machine in kind, and then use.
2. The machine can only run in a certain direction (see the arrow on the handwheel or shield), not reverse, so as not to damage the parts. When adjusting the pressure piece, you need to pay attention to it, don't be negligent.
3. Belt tension adjustment: through the electromechanical base plate on the two adjusting nuts to adjust. After adjusting, pay attention to lock.
4. electric pressure piece, before starting the upper punch should be in the rising position and then start. If the upper punch is in the down position to start, then just start to enter the middle mold pressing piece, this time because the speed of the machine has not gone up the inertia is small, easy to occur in the case of top car. (i.e., the upper punch into the middle mold due to the resistance of the tablet and "top dead", so that the machine stops running, the top of the car due to the load is large, often damage to the machine parts or burn the motor).
5. After the top of the car treatment
(1) in the electric tablet press the top of the car occurs, you should immediately turn off the power, so as not to burn the motor.
-5-
(2) when the top car situation is less serious, can be used by hand to turn the hand wheel to make the upstroke through the "dead point" (but do not reverse, so as to avoid the feeder to repeat the feed, resulting in more serious top car).
(3) serious top car, must remove the small shaft of the upper punch rod, so that it rises to reduce the pressure, and then turn the handwheel will be pushed out of the tablets, and then re-adjust the hardness of the tablets.
6. In the process of pressing tablets must be operated to check the quality of tablets (tablet weight, hardness, surface finish, etc.), timely adjustment.
7. Tablet pressing before the dosage preparation process has a great influence on the tablet pressing. Pharmaceutical materials and slippery materials, fillers, binders and other auxiliary materials of the formulation of particles of the situation (the condition of the powder, particle tightness, the proportion of powder, water content, etc.), are directly affecting the quality of tablets. And often due to improper formulation of granules can not be formed into tablets, and even damage the machine. Therefore, this machine can not be used for semi-solid or moist or no particles of fine powder tablet. In use, if you find that the pressure has been adjusted to a fairly large still can not be pressed into tablets or although pressed into tablets, but too loose, layer, fragments, pockmarks, powder and other phenomena, should be from the ingredients to find out the reasons, to be resolved. Do not adjust to increase the pressure, so as to damage the machine. In addition, some of the medicine pressed out of the hardness of the tablets, although not big, but with a certain degree of toughness, and its anti-shock resistance is not bad (usually from 1-1.2 meters high to fall on the ground can not be broken), so it should be used to meet the requirements of the operation of the custody of the degree of hardness do not focus on it alone, so as not to press the tablets under too much pressure, damage to the machine.
