Packaging paper traction mechanism used for packaging paper feeding device

Abstract

The invention discloses a packaging paper traction mechanism used for a packaging paper feeding device, relates to a filling machine and aims at solving the problem of not controlling the traction mechanism easily due to high coordination requirement with other devices of the filling machine. The technical scheme is as follows: a packaging paper traction mechanism used for a packaging paper feeding device comprises two relative plates, a friction roller rotationally connected with the two relative plates and a servo motor used for driving the friction roller; a paper inlet guide roller and a paper outlet guide roller are also arranged between the two relative plates; the friction roller is located between the paper inlet guide roller and the paper outlet guide roller; the two relative plates are respectively, vertically and fixed provided with travel guide plates between the friction roller and the paper outlet guide roller; and a gravity pressure roller slips between the two travel guide plates and is rotationally connected with the two travel guide plates. With the storage capacity of the packaging paper, the packaging paper traction mechanism used for the packaging paper feedingdevice provided by the invention can adapt to the intermittent filling machine without starting the servo motor, so the technical effect of convenient control can be achieved.

Description

technical field [0001] The invention relates to a filling machine, more specifically, it relates to a wrapping paper traction mechanism used in a wrapping paper feeding device. Background technique [0002] In the liquid food filling process, the manufacturing technology of forming brick-shaped packaging boxes or diamond-shaped packaging boxes from continuous packaging materials has been widely used. [0003] The production process of the filling machine generally includes, the packaging material is formed into a tube, that is, the packaging material is guided to bend and the two sides of the packaging material are heat-sealed to form a cylindrical hollow paper tube; food injection, that is, the food to be filled through the pipeline Inject into the hollow paper tube; volume forming and sealing, that is, heat seal the two ends of the cylindrical paper tube and cut off, so as to make a paper bag with both ends sealed and wrapped with the food to be filled; the filling box is ...

AI Technical Summary

Problems solved by technology

[0005] When producing large-capacity food boxes of more than 500ml, it may be necessary to use an intermittent filling machine. Therefore, there will be a pause for a certain period of time when the material is formed into a tube when the wrapping paper is taken. In order to adapt to this problem in the prior art, Generally, the pulling out of the wrapping paper is controlled by PLC controlling the start and stop of the traction mechanism, but this method requires too much coordination between the traction mechanism and other devices of the filling machine, and there is a problem that it is difficult to control; therefore, a new method needs to be proposed solution to this problem
