The automatic shrink packaging machine is an automatic packaging equipment that combines pneumatic components and mechanical devices, and is controlled by PLC and other peripheral circuits. The actuator of this equipment is a cylinder. The forward and backward are controlled by the two-position five-way solenoid valve. The working position of the cylinder is detected by the magnetic switch and the proximity switch and fed back to the PLC. The PLC sends a control command to the solenoid valve of the corresponding cylinder through the program to control the action of the cylinder. Below we introduce the packaging method and significance of the heat shrink packaging machine.
Packaging method of heat shrink packaging machine
1. Open at both ends
It uses a cylindrical film or a flat film to wrap the packaged object in a sleeve and then perform the heat shrinking operation. After the packaging is completed, there is a shrinking opening at both ends of the packaged object.
2. Sealed on all sides
Wrap the product around with flat film or cylindrical film, and the seams are sealed by lap joints. Used for product packaging that requires sealing.
3. Open at one end
Pallet shrink packaging is a typical example. First, the film is made into a big square bottom bag, and then the big bag is placed on the stacked commodity pallet from top to bottom, and then heat-shrinked. Place the pallet with the product on the conveyor belt and cover it with a shrink film bag; the conveyor belt will send it into the heat shrink tunnel, and then complete the shrink packaging after passing through the heat shrink tunnel. Its main feature is that the products can be firmly bundled in units of a certain amount, will not be loose during transportation, and can be stacked in the open.
4. Features and application of heat shrinkable film packaging machine
The heat shrinkable film packaging machine is a small heat shrinkable packaging equipment carefully manufactured in accordance with international standards. It has the characteristics of simple operation, wide application range, good airtightness, high transparency, low cost, and high grade. It is suitable for the packaging of small and medium batch products. The heat shrinkable film machine and the sleeve labeling machine are used online to form a sleeve labeling shrinking machine line, which is widely used in the fully enclosed heat shrinkable packaging of medicines, food, beverages, stationery, ceramics, daily chemicals, auto parts, knitting, electronic audio and video products, etc. , It is the sleeve label shrinking machine of the downstream packaging line.
The importance of heat shrink packaging machine
The heat shrink packaging machine is a highly automated equipment. The product is widely used in pharmaceuticals, food and beverage and household chemicals industries. The application of shrink film packaging machines can greatly reduce the material and labor costs of using mid-box packaging, which has important economic significance .
