Description

TECHNICAL FIELD

[0001] The present application relates to the field of automation production, in particular to a paper bag cylinder breaking device. BACKGROUND

[0002] The paper bag cylinder breaking device is a supporting device for automatic production of packaging paper bags, and the segmentation of the paper bag cylinder is a preceding process of bottom pasting of paper bag production. After the paper is formed into a cylinder, the traction roller transports the paper bag cylinder to the cutting knife position, and the rotary cutting knife cuts the paper bag cylinder to achieve the purpose of segmentation of the paper bag cylinder. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the paper bag cylinder breaking device.

[0003] The existing paper bag cylinder breaking device has certain drawbacks in use. The working gap of the cutting knife requires high accuracy, and the operator has certain requirements. If the gap of the cutting knife is too large, the paper bag cylinder cannot be cut off. If the gap of the cutting knife is too small, the cutting knife is easily damaged, the production efficiency is low, and the cutting speed of the paper bag cylinder depends on the speed of the traction roller. If the speed is too fast, the paper cylinder may not be straight, causing bag blocking and low production efficiency. At the same time, after the cutting knife cuts off the front paper cylinder, if the front end of the rear paper cylinder cannot enter smoothly, it will cause waste and affect production efficiency, which brings certain adverse effects to the use process of people. Therefore, we propose a paper bag cylinder breaking device. SUMMARY
