Plastic vest bag production device

Abstract

The invention relates to a plastic vest bag production device which mainly comprises an active placing mechanism, a feeding mechanism, a synchronous heat sealing mechanism, a die cutting mechanism anda bag folding mechanism. The synchronous heat sealing mechanism comprises a driving shaft and a chain group, a heat sealing knife is arranged on the driving shaft, and a heat sealing base matched with the heat sealing knife is arranged on the chain group. When plastic films pass the synchronous heat sealing mechanism, a motor of an active component drives the driving shaft to rotate through a gearbox, the driving shaft drives the chain group to rotate through a driving chain wheel and a driven chain wheel, the heat sealing knife and the heat sealing seat on the driving shaft and the chain group gradually approach and are pressed below a sliding seat top block in the transmission process of the driving shaft and the chain group, so that the conveyed plastic films are sealed in a heating manner, and the heat sealing knife and the heat sealing seat are gradually separated after heat sealing. According to the plastic vest bag production device, heat sealing, feeding and conveying can be synchronously performed, so that the production efficiency of plastic vest bags is improved.

Description

technical field [0001] The invention relates to a production equipment for plastic bags, in particular to a production equipment for plastic vest bags. Background technique [0002] As daily necessities, plastic bags are widely used by people, such as shopping bags in supermarkets, garbage bags, fresh-keeping bags, etc. Plastic bags are generally made of prepared plastic films and processed by plastic bag production equipment. During processing, plastic bag production equipment needs to perform operations such as sealing and cutting the plastic film to prepare plastic bags. One end of the plastic bag is the mouth, and the other end must be sealed, making it the bottom of the plastic bag for storing items. [0003] The sealing of plastic bags is generally achieved by heat sealing. Heat sealing is the most common and practical way of making bags in the application of recombined packaging materials. It uses various external conditions (such as electric heating, high-frequency ...

AI Technical Summary

Problems solved by technology

At present, there is no special mechanism for processing plastic bag material in the production equipment of plastic bags, and it is just allowed to fall to the ground or other workbenches, which will lead to poor hygienic environment in the plastic bag production workshop, and in the case of wind, Plastic bags will float around, which may affect the normal work of plastic bag production equipment
