1. Classified according to the position and number of strips sealed by the tape:
①I-type sealing machine. It seals with a strip of tape at the outer folded seam of the upper lid and lower bottom of the box. This kind of sealing, operation is simple, but the sealing is poor.
② H-type sealing machine. It is based on the I-type sealing, that is, in the I-type sealing tape on both ends of the sealing of two tapes, shaped like H, so called H-type. It can increase the box strength and sealing performance, but the cost is higher.
2. According to the degree of specialization:
①Universal sealing machine. It can adjust certain institutions to change the size of the sealing machine to adapt to a variety of sizes and specifications of the box sealing, it adapts to a wider range, is a commonly used sealing machine.
②Specialized sealing machine. It can only seal a certain size of the box, sealing speed, suitable for high-volume sealing operations.
3 random sealing machine. It is in the specified size range, the relevant agencies can automatically change to adapt to different sizes of the box sealing needs, is a very high degree of automation sealing machine. It is a kind of multifunctional packing machine. After the material enters into the top of the packing machine, the measuring part will feed the set quantity of products into the material channel in sequence. When passing through the outer wall of the material channel, the rolled packaging material is rolled into a cylinder by the former, and the longitudinal sealer seals the longitudinal seam firmly. The transverse sealer completes the top sealing of the bag and the bottom sealing of the next bag into two welded seams. As the downstream channel is wrapped by the bag, the bottom seal can be welded directly to the bag downstream, and then move a station to complete the top sealing, and cut off with the cutter to complete the packaging process.
Roll packaging materials are single-layer and composite. Single-layer such as moisture-proof cellophane, polyethylene, polypropylene, high-density polyethylene, composite such as stretch polypropylene / polyethylene, polyethylene / cellophane / aluminum foil. In addition, there are heat-sealable materials. Packaging sealing type has pillow sealing, three side sealing and four side sealing and so on. According to the filling principle filling machine is divided into atmospheric filling machine, pressure filling machine and vacuum filling machine.
① atmospheric pressure filling machine: it is under atmospheric pressure filling by liquid weight. This type of filling machine is divided into two kinds of timing filling and fixed capacity filling, only for filling low-viscosity liquids that do not contain gas, such as milk, wine and so on.
② pressure filling machine: it is higher than the atmospheric pressure filling, can be divided into two kinds: one is the pressure in the reservoir cylinder and the bottle pressure is equal to the liquid by the weight of the liquid into the bottle and filling, known as equal-pressure filling; the other is the pressure in the reservoir cylinder is higher than the pressure of the bottle, the liquid flows into the bottle by the pressure difference, high-speed production line more than this method. Pressure filling machine is suitable for gas-containing liquid filling, such as beer, soft drinks, champagne and so on.
③ Vacuum filling machine: the pressure in the bottle is lower than the atmospheric pressure for filling. This filling machine has a simple structure, high efficiency, the viscosity of the material to adapt to a wide range, such as oils, syrups, fruit wines, etc. can be applied. 1. Packaging machinery for a wide range of uses: market: food. Chemical. Medicine. Light industry are in use (machinery industry is relatively small) .
2. With easy to use (automatically complete the bag making, measuring, feeding, sealing, slitting, counting, printing lot number and other functions.)
3. High efficiency: the Chinese market packaging machine output can be close to 120-240 packets per minute to replace the 80's handmade products Output greatly exceeded the then several times.
4. Clean, hygienic and energy-saving clean and hygienic packaging machine no longer need to work manually can be used clean, hygienic, save materials, save bags, save money and environmental protection features.
5. Good visibility of the side-opening protective baffle, safe operation.
6, the use of the latest rocker plate cup adjustment device, can be adjusted at any time during the operation of the machine packaging capacity, reduce material loss, improve work efficiency;
Can automatically complete the bag making, measuring, feeding, sealing, cutting, counting, printing batch number (at the same time can be configured according to customer requirements) and other functions.
Classification and scope of application
Can include food vacuum packaging machine, household vacuum packaging machine, small vacuum packaging machine, desktop vacuum packaging machine, single-chamber vacuum packaging machine, double-chamber vacuum packaging machine, three-dimensional bag vacuum packaging machine, a variety of electronic vacuum packaging machine and so on; suitable for packaging a variety of food, meat products, seafood, fruits and vegetables, pickles, cooling meat, pharmaceutical products, hardware components, Medical equipment, etc. for packaging.
