What are the common packaging equipment?

by admin

packaging equipment refers to the equipment that can complete the packaging process of all or part of products and commodities. The packaging process includes filling, wrapping, sealing and other main processes, as well as related pre and post processes, such as cleaning, stacking and disassembly. In addition, packaging also includes measuring or stamping on the package. The use of mechanical packaging products can improve productivity, reduce labor intensity, meet the needs of large-scale production and meet the requirements of cleanliness and hygiene

The use of mechanical packaging products can improve productivity, reduce labor intensity, meet the needs of large-scale production and meet the requirements of cleanliness and hygiene
there are many classification methods for packaging equipment. It can be divided into single function packaging machine and multi-function packaging machine according to function; According to the purpose of use, it can be divided into inner packaging machine and outer packaging machine; According to the packaging type, it can be divided into special packaging machine and general packaging machine; According to the automation level, it is divided into semi automata and full automata. The following small series will introduce you to several commonly used packaging related equipment
cartoning machine is a machine used for product sales and packaging. It loads a measured quantitative material into the box and closes or seals the opening of the box. The packing machine is used to complete the transportation packaging. It loads the packaged finished products into the box according to a certain arrangement and quantity, and closes or seals the opening of the box. Cartoning machine and packing machine have the functions of container forming (or opening container), metering, loading, sealing and so on
the forming filling sealing packaging machine is a multifunctional packaging machine. After the materials enter the top of the packaging machine, the metering part will send the fixed quantity of products to the material channel in turn. When the drum packaging material passes through the outer wall of the material channel, it is wound into a barrel shape by the shaper, and the longitudinal sealer welds and seals it firmly. The transverse sealer completes the top seal of the packaging bag and the bottom seal of the next bag, forming two welds
. Since the blanking channel is wrapped by the packaging bag, after the bottom seal is sealed and welded, it can directly blanking into the bag, then move a station to complete the top seal, and cut off with a cutter to complete the packaging process
drum packaging materials are single-layer and composite. Single layer, such as moisture-proof cellophane, polyethylene, polypropylene and high-density polyethylene, and composite, such as stretched polypropylene /polyethylene, polyethylene /cellophane /aluminum foil. In addition, there are materials that can be heat sealed. Packaging sealing types include pillow sealing, three side sealing and four side sealing
the typical process is: the filling machine positions the hose container, seals the end of the container after metering and filling, and then sends it to the cartoning machine. The cartoning machine first forms the box blank, wraps the hose with lining paper, and then pushes it into the box to close the box opening. The small boxes are sent to the large box loader for stacking through the conveyor. After stacking a predetermined number, the large box blank forms a container in the form of wrapping, and at the same time, the small box is loaded into it and sealed with glue. The large boxes are transported to the packing machine for stacking, and loaded into the open boxes after reaching the predetermined quantity. After packing, the box cover shall be glued and sealed by the box sealing and banding machine, and the flush seam of the cover tongue shall be pasted with adhesive tape or the box shall be bound firmly by the strapping machine
according to the filling principle, liquid filling machines can be divided into atmospheric pressure filling machines, pressure filling machines and vacuum filling machines
the atmospheric pressure filling machine is used to fill under atmospheric pressure by liquid self weight. This kind of filling machine is divided into regular filling and constant volume filling. It is only suitable for filling low viscosity liquid without gas, such as milk, wine, etc
the pressure filling machine is used to fill at a pressure higher than the atmospheric pressure. It can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight, which is called isobaric filling; The other is that the pressure in the liquid storage cylinder is higher than that in the bottle, and the liquid flows into the bottle by pressure difference. This method is often used in high-speed production lines. Pressure filling machine is suitable for filling liquid containing gas, such as beer, soda, champagne, etc
the vacuum filling machine is used for filling when the pressure in the bottle is lower than the atmospheric pressure. The filling machine has the advantages of simple structure, high efficiency and wide application range for the viscosity of materials, such as oil, syrup, fruit wine, etc
the general process is as follows: the boxes with empty bottles are stacked on the pallets, sent to the pallet unloading machine by the conveyor belt, and the pallets are unloaded one by one. The boxes are sent to the unloading machine along with the conveyor belt, and the empty bottles are taken out from the boxes. The empty boxes are sent to the washing machine by the conveyor belt, cleaned, and then transported to the packing machine, so as to load the bottles containing drinks. The empty bottles taken out from the unloading machine are sent to the bottle washing machine for disinfection and cleaning by another conveyor belt. After being inspected by the bottle inspection machine and meeting the cleaning standards, they enter the filling machine and capping machine. The beverage is loaded into the bottle by the filling machine. The bottles filled with drinks are capped and sealed by the capping machine and transported to the labeling machine for labeling. After labeling, they are sent to the packing machine for loading into the box, and then sent to the pallet stacking machine for stacking on the pallet and sent to the warehouse.
