Sealing device for plastic bag containing chemical powder

Abstract

The invention discloses a plastic bag sealing device for chemical powder, comprising an automatic glue applicator, a spherical groove, a ball, a pressure switch, a moving plate, a flat applicator head, a mounting seat, an electric push rod, and a strip electromagnet , strip plate, L-shaped plate, connecting fixed seat, lifter, U-shaped frame, linear motor, load-bearing strip and return spring. The invention is reasonable in design and safe in operation, changes the traditional way of sealing plastic bags with hot-melt plastics, avoids the accidental heating and melting of chemical powder at the mouth of the bag during hot-melting and emits harmful gases, and facilitates sealing of the bag mouth Stretching and flattening are conducive to the next step of glue coating and sealing. By starting the linear motor, the automatic glue applicator is driven to move in a straight line, so that the flat mouth applicator with glue moves slowly at the bag mouth until the bag mouth is completely coated with glue , through glue bonding and solidification, to achieve the effect of sealing the bag mouth.

Description

technical field [0001] The invention relates to a plastic bag sealing device, in particular to a plastic bag sealing device for chemical powder, belonging to the technical field of chemical powder application. Background technique [0002] Plastic bags are an indispensable item in the daily life of human beings in modern society. They are often used to hold other items. They are widely used because of their low price, extremely light weight, bright colors, not afraid of falling, economical and durable, and easy to carry and store. , it has brought a lot of convenience to people's life, and it has become an indispensable item in daily life. , need to seal the plastic bag. [0003] Most of the existing plastic bag sealing facilities use hot-melt plastics to seal plastic bags. For some chemical powders in plastic bags, the chemical powder at the mouth of the bag is accidentally heated and melted during hot melting. It emits harmful gas, which is harmful to the operator's body...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing plastic bag sealing facilities use hot-melt plastics to seal plastic bags. For some chemical powders in plastic bags, the chemical powder at the mouth of the bag is accidentally heated and melted during hot melting. It emits harmful gas, which is harmful to the operator's body, and is prone to overheating, which will cause holes in the bag mouth at the seal, and the sealing effect is not good. At the same time, it is troublesome to clean up the plastic that sticks to the plastic bag sealing facility. Traditional plastic bag sealing The facility does not have the function of opening and flattening the bag mouth, and it is inconvenient to manually level the bag mouth
