Plastic bag packaging and opening device

Abstract

The invention discloses a plastic bag packaging and opening device. The plastic bag packaging and opening device comprises a first accommodating box with a bottom opening, a second accommodating box with a top opening and a tubular thin film in an attachment state. The first accommodating box is in hinge joint with the second accommodating box. The two sides of the first accommodating box and thesecond accommodating box are all provided with notches. The inner wall of the first accommodating box is provided with an air bag fixedly connected with the inner wall of the first accommodating box.The inner wall of the second accommodating box is provided with a laminar film fixedly connected with the inner wall of the second accommodating box. A cavity formed between the inner wall of the second accommodating box and the laminar film is filled with fluid. A magnetic attraction mechanism is arranged on the top of the interior of the first accommodating box. An opening mechanism for openingthe tubular thin film and with the air outlet function is arranged at one end of the tubular thin film. The opening mechanism is provided with a first magnet attracted with the magnetic attraction mechanism. A filling mechanism is arranged on the opening mechanism. Heat sealing mechanisms are arranged on the two sides of the first accommodating box and the second accommodating box correspondingly.The plastic bag packaging and opening device can reduce damage to the thin film due to gravity and material fluidity and can reduce material pollution caused during packaging.

Description

technical field [0001] The invention relates to packaging processing equipment, in particular to a plastic bag packaging stretching device. Background technique [0002] The existing films are all in a bonded state after production. When packaging materials with strong fluidity, it is necessary to pack a layer of film on the surface of the material, and then put a thicker bag on the outer layer of the film. Moreover, in order to reduce the probability of film damage, it is necessary to place the film horizontally and fill it with material, but due to the fluidity of the material and the effect of gravity, the material often flows to the bottom of the middle area of ​​the film, resulting in a hole in the film, while the existing The packaging method is not suitable for the packaging of such materials, and it cannot isolate the materials from the outside world, which may easily cause contamination of the materials. Contents of the invention [0003] The problem to be solved...
