Stretch film automatic packaging machine for raised folds shrunk by preheating based on stretch-resisting winding

Abstract

The invention discloses a stretch film automatic packaging machine for folds shrunk by preheating based on stretch-resisting winding. The machine comprises a conveyor belt, a wound film roller rack, afilm band barrel, a vertical bar frame, a human-machine interface, a wind-resisting heat shrinkage raised seat, a packaging machine tank slot and a stretch roller. According to the machine, the wind-resisting heat shrinkage raised seat fits in the packaging machine tank slot, the effects of shrinking the integral film surface and then lifting the top support lifting plate groove to push and thensmooth the corrugated folds are achieved through friction pre-heating of an arc rod cushion buckle frame and a line distance wheel guide frame, the integral film surface is retracted and the displacement deviation is subjected to the raised correction, the controllability of the integral linear speed feeding vector is guaranteed, the integral film surface tension sensing and conveying anti-friction force are improved, the loss of the stretch film surface is reduced, preheating processing and shaping processing effects are formed, the stretch-resisting winding operation forms a reciprocating film surface superimposed thickening effect, breakable single-layer film is subjected to the toughness superimposed reinforcement and protection, and the precision blending effect of whole process lineis improved.

Description

technical field [0001] The invention relates to a stretch film automatic packaging machine based on drag-and-twist preheating shrinkage and pleating, and belongs to the field of automatic packaging equipment. Background technique [0002] The stretch film of the automatic packaging machine uses film hot pressing or direct vacuum packaging to ensure the freshness and quality of the packaging materials and the stability of the service life of the materials, and the automatic packaging can work continuously in large quantities and save labor. The current technology is common The disadvantages to be optimized are: [0003] The film bag of the stretch film automatic packaging machine has strong toughness but is easy to shrink when heated, which will cause the heated edge of the rolling friction base to slide and pull in the automatic packaging transmission, and the heated edge will be corrugated, which will interfere with the sealing of the side during packaging and make the corr...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automatic stretch film packaging machine based on drag-winding preheating shrinkage and pleating to solve the problem that the film bag of the stretch film automatic packaging machine has strong toughness but is easy to shrink when heated. , which will cause the heated edge of the rolling friction base to slide and pull in the automatic packaging transmission to be corrugated, which interferes with the sealing of the side during packaging, making the corrugated folds thicken the film surface and the air gap, and allowing the fresh-keeping packaging materials to be oxidized by the internal airflow , reduce the quality of product preservation, and also lead to the indentation of the frame in the later stage, which affects the transmission of the overall rack assembly line, resulting in differential speed offset caused by rolling friction conveying and conveyor belt displacement, so that the length and length of the side and side are uneven, making the pull The stretching surface is inclined, which interferes with the automatic assembly line operation
