I. Introduction of three-side bag sealing machine

With the development of food packaging industry today, people's demand for plastic composite film bags and other materials is also increasing. The three-sided bag-making machine (as shown in Figure 1) is used to produce all kinds of plastic-plastic and paper-plastic composite materials. It is widely used for the three-sided bag-making of plastic composite film, aluminum-plastic composite film, paper-plastic composite film, etc. It is an ideal bag-making equipment for all kinds of middle sealing and three-sided sealing. At the same time, it is suitable for the manufacturing of self-supporting bags, concave and convex buckle bags, zipper bags and other shaped bags.

Ii. Equipment structure

The structure of the three-side bag making machine is mainly composed of the following parts:

1. Rear discharging mechanism: The discharging tension is controlled by frequency converter and magnetic powder clutch;

2. Heat sealing mechanism: Driven by frequency conversion device to do up and down reciprocating movement, the thermocouple heats the sealing knife to achieve the effect of sealing the bag. It is composed of horizontal sealing and vertical sealing.

3, conveying mechanism: driven by servo feeding roller, achieve the purpose of feeding, to ensure that the heat sealing mechanism in the left bearing roller and bearing again reached before cutting roller, will set the length of the plastic bag to send overheating institutions, including the servo near the cutter works have two kinds, one kind is fixed-length patterns: set to walk the length of the pulse is stopped and the other is a calibration model: the number of pulses through setting low speed searching, color code photoelectric signal is stopped. The other 3 servos are synchronized with them.

4. Knife cutting mechanism: Cut the bag after heat sealing;
