PE film hot sealing bag making machine

Abstract

The invention discloses a PE film hot sealing bag making machine. The PE film hot sealing bag making machine comprises a main frame, a feeding device, a transverse sealing device, a traction device, alongitudinal sealing device, a positioning device, a cutting device, and a collecting device arranged on the main frame in sequence, each of the transverse sealing device and the longitudinal sealingdevice comprises a hot sealing frame, a first upper lifting driving piece and a first lower lifting driving piece mounted on the hot sealing frame, an upper hot sealing cutter assembly and a lower hot sealing cutter assembly respectively mounted on the first upper lifting driving piece and the first lower lifting driving piece, and an air-cooling assembly mounted on the upper hot sealing cutter assembly and the lower hot sealing cutter assembly, the upper hot sealing cutter assembly comprises a first upper cooling plate, a first upper insulation plate, an upper heating electric resistance wire, and a first upper isolation piece arrayed from top to bottom and connected in sequence, and the lower hot sealing cutter assembly comprises a first lower cooling plate, a first lower insulating plate, a lower heating electric resistance wire, and a first lower insulating piece. The PE film hot sealing bag making machine can effectively carry out the hot sealing on the PE film so as to improve the quality of the PE film bag preparation.

Description

technical field [0001] The present invention relates to a bag-making machine, more specifically to a PE film heat-sealing bag-making machine. Background technique [0002] Bag making machine is a kind of equipment used to make packaging bags. The plastic film is divided into upper film and lower film, which are guided and conveyed separately, and then overlapped at a suitable position. The overlapped upper film and lower film are edge-sealed horizontally and vertically. Finally, a plurality of bag structures are formed, and finally it is cut with a cutter to form a plurality of bags. [0003] In the prior art, the edge sealing device of the bag making machine is a constant temperature heating structure. In the process of heat sealing the PE film bag body, the PE film will soften, causing the PE film to break easily when being pulled, thus causing The bag-making machines in the prior art cannot heat-seal PE, or the effect of heat-sealing is poor, resulting in unstable and ea...

[0003] In the prior art, the edge sealing device of the bag making machine is a constant temperature heating structure. In the process of heat sealing the PE film bag body, the PE film will soften, causing the PE film to break easily when being pulled, thus causing The bag making machine in the art cannot heat seal PE, or the heat sealing effect is poor, resulting in unstable and easily damaged PE film bags during use
