Nozzle-added type liquid bag making machine suitable for heat sealing of various film materials

Abstract

The invention discloses a nozzle-added type liquid bag making machine suitable for heat sealing of various film materials. The nozzle-added type liquid bag making machine comprises a main rack, and adischarging device, an adjusting device, a distributing device, a patching device, a perforating device, a valve welding device, a converging station, a transverse sealing mechanism and a longitudinalsealing mechanism arranged on the main rack, wherein the transverse sealing mechanism and the longitudinal sealing mechanism each comprise an upper heat sealing cutter assembly, a lower heat sealingcutter assembly, a cooling assembly, a transverse cutter device, a longitudinal sliding cutter device and a pulse heating welding power source, and are electrically connected with a patch heating resistance wire, a valve body welding ring, an upper heat sealing cutter assembly, a lower heat sealing cutter assembly, a patch resistance wire cooling plate assembly, a welding ring cooling grinding tool assembly and a cooling assembly. Heating of the patch heating resistance wire, the valve body welding ring, the upper heat sealing cutter assembly and the lower heat sealing cutter assembly and water cooling of the patch resistance wire cooling plate assembly, the welding ring cooling grinding tool assembly and the cooling assembly are controlled by the transverse sealing mechanism and the longitudinal sealing mechanism. The nozzle-added type liquid bag making machine is suitable for heat sealing of various materials, and the universality of bag making is remarkably improved.

Description

technical field [0001] The invention relates to a mechanical bag making device, more specifically to a nozzle-filling liquid bag making machine suitable for heat sealing of various film materials. Background technique [0002] Bag making machine is a kind of equipment used to make plastic packaging bags. It is used to compound the upper plastic film and the lower plastic film. The overlapped upper film and lower film form multiple bag structures after horizontal and vertical edge sealing, and finally cut them with a cutter to form multiple independent bags. [0003] In the prior art, the edge banding device of the bag making machine is a constant temperature heating structure, which makes it only suitable for heating edge banding of composite films, but cannot degrade the surface layer of pure PE film, co-extrusion film, new materials PLA, PBAT The film is heat-sealed. The reason is that during the heat sealing process of PE film, co-extruded film, new material PLA, PBAT d...

[0003] In the prior art, the edge banding device of the bag making machine is a constant temperature heating structure, which makes it only suitable for heating edge banding of composite films, but cannot degrade the surface layer of pure PE film, co-extrusion film, new materials PLA, PBAT The film is heated and edge-sealed

The reason is that during the heat sealing process of PE film, co-extruded film, new material PLA, PBAT degradable film, PE film, co-extruded film, new material PLA, PBAT degradable film will soften, and the softened film is pulled easy to break
