Technical Field

[0001] The utility model relates to the technical field of heat sealing mechanisms, in particular to a plastic heat sealing mechanism. Background Art

[0002] In the production process of plastic bags and films, heat sealing mechanism plays a vital role. This equipment uses heat sealing technology to efficiently and accurately seal plastic films, providing a reliable method for sealing and packaging products. The working principle of the heat sealing mechanism is mainly to generate high temperature through the heating element. Under the action of the heat sealing strip, the materials of the plastic film are bonded together to form a firm seal.

[0046] Working principle:

[0047] The plastic heat sealing mechanism places the plastic bag on the first conveyor 1, and places the position to be sealed outward to a suitable position according to the position of the first heating strip 208, and starts the first conveyor 1 and the motor 301.

Before heat-sealing, the first electric telescopic rod 202 is started to drive the base 210 to move the two first heating strips 208 to a suitable position to facilitate heating of the plastic bag. By setting three heating structures, the uniformity of the heat conduction effect of the heating strip is effectively improved, the consistency of the heat sealing quality is ensured, and the quality of the product and the production efficiency are effectively improved.
