Breaking device for paper bag tube

Abstract

The invention discloses a paper bag tube snapping device which comprises a device body, a cam, a swing arm, a swing arm shaft, a first connecting rod and a swing shaft are installed on the outer side of the device body, the cam is connected with the swing arm, the swing arm shaft is installed on the swing arm, and the first connecting rod is connected with the swing arm and the swing shaft. A fourth belt, a driven roller, a second belt and a first belt are arranged in the device body, an air cylinder is installed on the inner side of the upper end of the device body, a third connecting rod and a fourth connecting rod are connected to the outer side of the fourth belt, and a fourth clamping roller and a driving roller are arranged in the movable roller. According to the snapping device for the paper bag cylinder, the cutter does not need to be adjusted frequently, meanwhile, the tensioned paper bag cylinder is more convenient to cut, the front end of the paper bag cylinder enters the belt when the previous bag cylinder is snapped, the continuity of paper falling is guaranteed, the production efficiency is improved, the problem that the cutter is difficult to adjust is solved, and the production efficiency and the yield are improved.

Description

technical field [0001] The invention relates to the field of automated production, in particular to a device for breaking a paper bag tube. Background technique [0002] The breaking device of the paper bag tube is a supporting device for the automatic production of packaging paper bags. The segmentation of the paper bag tube is the previous process of producing the bottom of the paper bag. After the paper is formed into a tube shape, the long paper bag tube is cut into The required size of the paper bag, the existing automatic cutting and segmentation technology of the paper bag tube, after the paper is formed into a paper bag tube, the traction roller transports the paper bag tube to the cutter position, and the rotary cutter cuts the paper bag tube, so as to achieve the separation of the paper bag tube. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the pull-off device for the paper ba...

Problems solved by technology

[0003]There are certain disadvantages in the use of the existing breaking device for the paper bag tube. If the gap is too large, the paper bag tube cannot be cut; if the gap between the cutter is too small, it will easily cause damage to the cutter and the production efficiency will be low. The cutting speed of the paper bag tube depends on the speed of the traction roller. If the speed is too fast, it will easily cause the paper tube to run The line is not straight, resulting in bag blockage and low production efficiency; at the same time, after the cutter cuts off the front section of the paper tube, if the front end of the rear paper tube cannot enter smoothly, it is easy to cause waste products and affect production efficiency, which brings certain problems to people's use process. adverse effects, for this reason, we propose a pull-off device for paper bag tubes
