Roll changing and material receiving mechanism of film blowing machine

Abstract

The invention discloses a roll changing and material receiving mechanism of a film blowing machine, and relates to the technical field of film blowing machines, the roll changing and material receiving mechanism comprises a roll changing and material receiving mechanism main body, the roll changing and material receiving mechanism main body comprises a mechanism frame, the front end of the mechanism frame is movably provided with a film feeding roller, and the lower end of the mechanism frame is provided with a cutting device. By installing the roll changing guide mechanism, a film produced by a film blowing machine is conveyed to the roll changing guide mechanism through the film feeding roller, the film guiding roller plays a role in guiding the film, and the fixed shaft and the movable sleeve are matched with each other to enable the film guiding sleeve to rotate to reduce the friction force between the film guiding sleeve and the plastic film; a rubber plate, a rotating rod and a spring connecting rod are matched with one another to play a role in enabling a film guide sleeve to have elastic force and buffer tension, the situation that a plastic film is broken due to too large tension is avoided, when roll replacement is needed, a handle is rotated, a reversing frame rotates by a certain angle, the output direction of the plastic film is changed to the other side under the action of a film guide roller, roll replacement is convenient, and the production efficiency is improved. The problem that the machine needs to be stopped when the receiving roller is replaced is solved.

Description

technical field [0001] The invention relates to the technical field of film blowing machines, in particular to a film blowing machine rewinding and rewinding mechanism. Background technique [0002] The film blowing machine is a special equipment for producing plastic film. The plastic film needs to be rewound through the rewinding mechanism from blowing out to forming a roll. Therefore, it is necessary to use the film blowing machine to change the rewinding mechanism. [0003] There are following problems at prior art: [0004] 1. In the prior art, the receiving mechanism needs to stop the machine after the receiving shaft is full of a roll of material, and then manually remove the receiving shaft and replace it with a new receiving shaft for reinstallation. Low efficiency and high labor intensity; [0005] 2. In the prior art, the plastic film of the receiving mechanism needs to be cut off when the roll is changed, and then it needs to be manually picked up and glued to ...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a film blowing machine rewinding and rewinding mechanism, one of the purposes of which is to facilitate the reversing and dismantling of the rewinding roller, and solve the need for the rewinding mechanism to turn the machine when the rewinding shaft is full of a roll of material. Stop and manually disassemble and remove the rewinding shaft and then replace it with a new rewinding shaft to reinstall the problem of low production efficiency; another purpose is to solve the problem that the plastic film needs to be cut off when the rewinding mechanism is changing rolls. The problem that it needs to be manually picked up and glued to the new take-up roller to achieve the effect of automatically cutting off the transition
