Continuous cooling device for discharged plastic bags

Abstract

The invention discloses a plastic bag discharging continuous cooling device, and relates to the technical field of plastic bag film blowing machine cooling devices.The plastic bag discharging continuous cooling device comprises an outer ring, inner ring pipes and an air cooling assembly, telescopic rods are installed in the outer ring, the inner ring pipes are fixed to the top ends of the telescopic rods, outer corrugated pipes are connected between the inner ring pipes, ventilation openings are formed in the inner sides of the inner ring pipes, and the ventilation openings are communicated with the air cooling assembly. And the air cooling assembly is arranged on the periphery of the interior of the inner ring pipe, the air cooling assembly comprises an installation air chamber, a heat dissipation fan, a corrugated sleeve, a ventilation pipe, an air outlet, a connecting flange and an inner corrugated pipe, the heat dissipation fan is installed in the installation air chamber, and the corrugated sleeve is connected to the inner side of the installation air chamber. According to the continuous cooling device for the discharged plastic bag, the outer ring can be additionally arranged on the periphery of the blown film discharging part, the adjustable blowing device is arranged in the inner ring pipe, the front-back blowing position and the blowing angle can be conveniently adjusted, and therefore the film barrel can be rapidly cooled.

Description

technical field [0001] The invention relates to the technical field of cooling devices for plastic bag film blowing machines, in particular to a continuous cooling device for plastic bag discharge. Background technique [0002] Commonly used food packaging plastic bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a film made of polyvinyl chloride, polyvinyl chloride itself is non-toxic, but the additives added according to the use of the film are often harmful substances to the human body, have certain toxicity, and are not suitable for containing food. Plastic bag processing needs to use blown film forming. The blown film machine heats and melts the plastic particles and then blows them into a film. There are many types of blown film machines, such as PE, POF, PVC and so on. During the use of the film blowing machine, a cooling device is required to cool the film cylinder of the film blowing machine used for contin...

Problems solved by technology

[0003] The cooling device used in the existing plastic bag film blowing machine is inconvenient to adjust the size of the inner diameter, and it is not convenient to adjust the wind direction of the air outlet, and the air outlet is not uniform enough during cooling, and the cooling efficiency is not good. Therefore, we propose a plastic bag Discharge continuous cooling device
