What are the packaging machinery and equipment?
Packaging equipment is a kind of machinery specially used for commodity packaging. The use of packaging machinery can greatly improve the efficiency of packaging process. The demand for packaging machines for different products is also different, so there are variant types of packaging machines in the market. And the following is a brief introduction to the common types of packaging machinery:
1. Shrinking machine
Shrinking machine is a highly automated equipment. This product is widely used in pharmaceutical, food and beverage and home chemical industries. The application of shrink film packaging machine can greatly reduce the material and labor costs of medium box packaging, which has important economic significance. The automatic shrink packaging machine is an automatic packaging device that combines pneumatic elements and mechanical devices and is controlled by PLC and other peripheral circuits. The execution unit of the device is the cylinder. Its advance and retreat are controlled by two-position five-way solenoid. The working position of the cylinder is detected by the magnetic opening and proximity switch and fed back to the PLC, and the PLC sends a control command to the solenoid valve of the corresponding cylinder through the program to control the movement of the cylinder.
2. Strapping machine
Strapping machine, semi-automatic strapping machine, fully automatic strapping machine, and carton strapping machine. Now it is widely used in our packaging and printing, chemical, recycling, electronics and other industries. By using strapping belts to tie it tightly so that the product is not easy to scatter during transportation and visually beautiful and tidy.
3. Sealing machine
The sealing machine for the container to contain the product. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain the product quality and avoid product loss, the container needs to be sealed. This operation is completed by the sealing machine.
The internal pumping vacuum machine consists of a vacuum pump, a vacuum chamber, a heating transformer, a heating table, a plexiglass plate cover, an air bag, a solenoid valve, a time relay, a power indicator light, an air switch, a vacuum gauge, a gear switch, an emergency stop switch, an AC Contactor, and other components.
5. Filling machine
Filling machines are mainly a small category of products in packaging machines, which can be divided into liquid filling machines, paste filling machines, powder filling machines, and particle filling machines from the perspective of packaging materials; from the degree of automation of production It is divided into semi-automatic filling machine and fully automatic filling production line. Recently, with the QS certification of food, edible oil manufacturers have begun to pay attention to product quality and packaging as well.
