What is a plastic bag sealing machine? Principle and structure description
Add Time：2022-02-22 06:52:37
1. What is a plastic bag sealing machine?
The plastic bag sealing machine is suitable for the sealing and packaging of plastic bags. It can seal plastic films of various materials (PE, PP, aluminum film, etc.) Specific plastic bag packaging machines can be divided into multi-functional film continuous sealing machines, plastic film sealing machines, floor-standing film sealing machines, etc. It is an ideal sealing machine for aluminum foil bags, plastic bags and composite bags in the industries of medicine, pesticide, food, daily chemical, lubricating oil and so on. It can run continuously, and can also print the date, batch number, etc. according to user needs. Suitable for pipeline work.
Second, the principle structure of plastic bag sealing machine
1. The machine is composed of frame, deceleration and speed regulation transmission mechanism, heating and cooling mechanism, sealing and printing mechanism, conveying device and electrical and electronic control system and other components;
2. Turn on the power, and the agencies start to work. The electric heating element is heated after being energized, so that the upper and lower heating blocks are heated up sharply and adjusted to the required temperature through the control system; the imprinting wheel rotates; the cooling system starts to cool according to the needs; the conveyor belt is rotated and adjusted to the required speed by the speed regulating device ;
3. When the package containing the articles is placed on the conveyor belt, the sealing part of the bag is automatically sent to the two sealing belts in operation and brought into the heating area, and the heat of the heating block is transmitted to the sealing part of the bag through the sealing belt. , the film is heated and melted and softened, and then passed through the cooling zone to make the surface temperature of the film drop appropriately, and then rolled by a knurling wheel (or printing wheel) to bond the upper and lower plastic films of the sealing part and press out a mesh pattern (or printing). The sealed bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
