Production process of multifunctional packaging machine:
Molding filling sealing
After the materials enter the top of the packaging machine, the metering part will send the fixed quantity of products into the material channel in turn. When the drum packaging material passes through the outer wall of the material channel, it is wound into a cylinder by a shaper, and the longitudinal seam seal is firmly welded by the longitudinal sealer. The horizontal sealer completes the top seal of the package bag and the bottom seal of the next bag, forming two welding seams. As the blanking channel is wrapped by the packaging bag, the material can be directly fed into the bag after the bottom sealing and welding, and then a station is moved to complete the top sealing and cutting 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, high-density polyethylene, composite such as tensile polypropylene / polyethylene, polyethylene / cellophane / aluminum foil. In addition, there are heat sealing materials. There are pillow seal, three side seal and four side seal. The cartoner is used for the packaging of product sales.
Cartoning machine is used for product sales and packaging machinery;
It will measure a quantitative material into the box, and the opening part of the box is closed or sealed. The packing machine is used to complete the transportation packing. It packs the finished products into the box according to a certain arrangement and quantity, and closes or seals the opening part of the box. Both cartoner and packer have the functions of container forming (or opening container), measuring, loading and sealing. The typical process is as follows: the filling machine positions the hose container, seals the end of the container after metering and filling, and then sends it to the cartoner. The box filling machine first forms the box blank, wraps the hose with lining paper, and then pushes it into the box to close the box mouth. The small boxes are sent to the big box machine for stacking by the conveying device. After stacking a predetermined quantity, the large box blank forms a container in the way of wrapping, and at the same time, the small box is put into the container and sealed with glue. The large boxes are transported to the packing machine for stacking, and then loaded into the open boxes after reaching the predetermined quantity. After packing, the case cover is glued and sealed by a case sealing and pasting machine, and the case is bound firmly by adhesive tape or strapping machine.
atmospherical pressure filling machine
Atmospheric pressure filling machine is under atmospheric pressure by liquid self weight filling. This kind of filling machine can be divided into two kinds: regular filling and constant volume filling. It is only suitable for filling liquid with low viscosity and no gas, such as milk and wine.
Pressure filling machine
The pressure filling machine can be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and it is filled by the self weight of the liquid into the bottle, which is called equal pressure filling; the other is that the pressure in the storage tank is higher than the pressure in the bottle, and the liquid body flows into the bottle by the 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.
Vacuum filling machine
This kind of filling machine has simple structure and high efficiency, and can be used in a wide range of viscosity of materials, such as oil, syrup, fruit wine, etc.
The process is generally as follows: boxes with empty bottles are stacked on pallets, which are sent to the palletizer by 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 through the conveyor belt, cleaned and then transported to the side of the packing machine, so as to put the bottles containing drinks into them. The empty bottles taken out from the unloading machine are sent to the bottle washing machine by another conveyor belt for disinfection and cleaning. The bottles are inspected by the bottle inspection machine and enter the filling machine and capping machine after they meet the cleaning standards. The beverage is bottled by a filling machine. The bottles filled with drinks are sealed by the capping machine and transported to the labeling machine for labeling. After being labeled, the bottles are sent to the packing machine for packing, and then to the palletizing machine for stacking on the pallets and sent to the warehouse.
The process of bottle filling line for various drinks is basically similar. However, due to the different nature of the beverage, the filling machine and capping machine used are also different. For example, beer filling line in addition to the selection of suitable filling and capping machine, but also add a sterilization machine. According to the different cover shapes (crown cap, screw cap, plug, etc.) used in capping machine, the corresponding models are selected.
