What is shrink wrap? Shrink wrap is a machine that wraps a product with a heat-shrinkable film and then heats it to shrink the film and wrap it. According to the type of machine, it is divided into drying tunnel shrinking machine, oven shrinking machine, frame shrinking machine and gun shrinking machine.
The shrink wrap machine is a highly automated device widely used in the pharmaceutical, food and beverage, and home chemicals industries. The use of shrink film packaging machines can greatly reduce the material and labor costs of the use of the middle box packaging, which has important economic significance.The automatic shrink packaging machine is a combination of pneumatic components and mechanical devices, and automatic packaging equipment controlled by PLC and other peripheral circuits. The actuator of the device is a cylinder. It is controlled by the two-position five-way solenoid valve to advance and retreat. 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, thereby controlling the movement of the cylinder.
According to the film, it can be divided into p film shrinking machine and pof film shrinking machine;
According to the heating method, it can be divided into quartz tube heating and stainless steel heating;
According to the speed regulation, it can be divided into electronic speed regulation and frequency conversion speed regulation.
