Packaging equipment refers to the completion of all or part of the product and commodity packaging process equipment. Packaging process includes filling, wrapping, sealing and other major processes, as well as its related processes, such as cleaning, stacking and dismantling. In addition, packaging also includes measuring or stamping on the package, and other processes. The use of mechanical packaging products can improve productivity, reduce labor intensity, to adapt to the needs of mass production, and to meet the requirements of cleanliness and hygiene.
Packaging equipment and a variety of classification methods. According to the function can be divided into single-function packaging machine and multi-function packaging machine; according to the use of the purpose can be divided into inner packaging machine and outer packaging machine; according to the packaging varieties can be divided into special packaging machine and general packaging machine; according to the level of automation is divided into semi-automatic machine and fully automatic machine. The following is a small introduction for you to several commonly used packaging-related equipment.
Cartoning machine is used for product sales packaging machinery, it will be measured by a quantitative material into the box, and the box opening part of the closed or sealed. Cartoning machine is used to complete the transportation packaging, it will be packaged according to a certain arrangement and quantitatively loaded into the box, and the opening part of the box closed or sealed. Cartoning machine and cartoning machine both have container forming (or open container), measuring, loading, sealing and other functions.
The form-fill-seal packaging machine is a multifunctional packaging machine. After the material enters the top of the packaging machine, the measuring part feeds 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 wound into a cylinder by the formers, and the longitudinal seals are firmly welded by the longitudinal seams of the longitudinal seals. 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 a 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 pillow seal, three side seal and four side seal.
The typical process is: filling machine to make the tube container positioning, by measuring the filling and sealing the end of the container, and then sent to the cartoning machine. Cartoning machine will be the first box blank molding, the hose wrapped in liner paper, pushed into the box to close the box mouth. Small boxes are conveyed to the cartoning machine for stacking. After stacking a predetermined number of boxes, the large box blanks are wrapped to form a container, and at the same time, the small boxes are loaded into it and sealed with glue. The large boxes are conveyed to the cartoning machine for stacking and are loaded into open boxes after reaching a predetermined quantity. After packing, the lid of the box is glued and sealed by the box sealing and sticking machine, and the tongue of the lid is taped at the flush seam or the box is strapped firmly by the strapping machine.
Liquid filling machine according to the filling principle can be divided into atmospheric filling machine, pressure filling machine and vacuum filling machine.
Atmospheric pressure filling machine 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, is only suitable for filling low viscosity does not contain gas liquid such as milk, wine, etc..
Pressure filling machine is higher than the atmospheric pressure filling, can also 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 isobaric pressure filling; the other is the pressure in the reservoir cylinder is higher than the pressure in the bottle, the liquid by the pressure difference into the bottle, high-speed production line more than the use of this method. Pressure filling machine is suitable for gas-containing liquid filling, such as beer, soft drinks, champagne and so on.
Vacuum filling machine is in the bottle pressure is lower than atmospheric pressure filling. This filling machine has a simple structure, high efficiency, and a wide range of adaptability to the viscosity of the material, such as oils, syrups, fruit wines, etc. can be applied.
The process is generally as follows: the box with empty bottles stacked on a pallet, sent by conveyor belt to unload the pallet machine, the pallet is unloaded one by one, the box with the conveyor belt to the unloading machine, the empty bottles from the box out of the empty box, the empty box through the conveyor belt to the box washer, after cleaning, and then transported to the box machine, in order to contain the beverage bottles filled with them. Empty bottles taken out from the unloading machine are sent by another conveyor belt to the bottle washer to be sterilized and cleaned, and then inspected by the bottle inspection machine to meet the cleanliness standard before entering the filling machine and capping machine. Beverages are loaded into bottles by the filling machine. Bottles filled with beverages by the capping machine to seal the cap and conveyed to the labeling machine labeling, labeling and then sent to the cartoning machine into the box and then sent to the stacking pallet machine stacked on the pallet into the warehouse.
