A film pulling mechanism for carrying bags

Abstract

The invention provides a film-drawing and bag-carrying mechanism. The film-drawing and bag-carrying mechanism comprises a material feeding, cutting and sealing device, a film drawing device, a base plate and a bag carrying device, wherein the material feeding, cutting and sealing device, the film drawing device and the bag carrying device are separately borne by the base plate; the material feeding, cutting and sealing device and the film drawing device are separately connected with the bag carrying device; the material feeding, cutting and sealing device comprises a material feeding mechanism, a sealing and cutting mechanism and a lower tool apron component; the material feeding mechanism is connected onto one side of the sealing and cutting mechanism; the lower tool apron component is connected onto the lower end of the sealing and cutting mechanism; the material feeding mechanism comprises film guiding rollers and film placement rollers; the film drawing device comprises a film drawing part and a film clamping part; and the film drawing part is connected with the film clamping part. By adopting the structure, the cost is reduced; package film raw materials are not wasted; the production efficiency is improved; the film conveying speed can be improved; and a product can be packed rapidly.

AI Technical Summary

Problems solved by technology

This packaging machine is suitable for continuous packaging of shaped items, but it has the following disadvantages for intermittent packaging of unshaped items: the heat loss of the tunnel-type heating box is large; since the electric heating element is only set on the upper part of the tunnel-type heating And the lower part, the film is heated unevenly, and the film is prone to rupture when packing some thicker items, and the packaging speed is slow, resulting in a lot of waste film, resulting in a waste of raw materials

Although the packaging equipment in Italian patent 1024614 is small in size and easy to operate, the packaging equipment implemented according to this patent can only be used in such a way that it is planned to be used in certain special departments to achieve packaging speed, If only a small number of items are packed per day, its potential is wasted and may be difficult to handle on some occasions
