Tubular film bag opening device

Abstract

The invention discloses a cylinder moving type film bag opening device. The cylinder moving type film bag opening device comprises a base, a movable frame, an air cylinder structure and an air pipe. An air outlet head communicates with the air cylinder structure through the air pipe. The air outlet head is arranged on the base, and an outlet of the air outlet head faces the part between a top suction cup and a bottom suction cup. The air cylinder structure comprises a cylinder body, a push rod and a piston. The piston is located in the cylinder body with the closed bottom, the edge of the piston is matched with inner wall of the cylinder body, and the piston can vertically move in the cylinder body. The part, close to the bottom of the cylinder body, of the air pipe is connected with the cylinder body to achieve communication. The lower end of the push rod is connected with the piston. The air outlet head communicates with the air cylinder structure through the air pipe so that the problem that the suction force of the top suction cup and the bottom suction cup is not good, and an upper-layer film and a lower-layer film are attached again after being opened can be solved. Accordingly, a consumer can conveniently open a bag opening. The cylinder moving type film bag opening device is simple in structure, low in cost and easy to manufacture.

Description

technical field [0001] The invention relates to a cylinder-operated film bag opening device, which can be used for opening film bags. Background technique [0002] In the prior art, a lot of film bags are needed to be used for packing bulk items (such as fruit, rice, etc.) in a large supermarket, and the film bags are generally innumerable bags connected end to end, and these bags are wound on a shaft to form a roll, and then The reel is placed on the shelf, and when a bag is to be taken, a complete film bag is pulled out, and then torn off at the break, so that a film bag is obtained. However, due to various reasons such as static electricity, and due to the comprehensive effect of the bag being rolled together and pressed tightly for a long time, the mouth of the film bag often sticks together, and the film is relatively thin, so it is difficult to separate the mouth of the bag by pinching and rubbing with fingers. , it is difficult to open the bag mouth, which can easily...
