Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber paper tube processing, and particularly relates to a chemical fiber paper tube anti-bending and cracking processing device. Background Art

[0002] Chemical fiber paper tubes are paper tubes formed by bonding several layers of paper with glue and then winding them. They are mainly used in chemical fiber winding and spinning processes. The quality of chemical fiber paper tubes directly affects the spinning process. During the production of chemical fiber paper tubes, long paper tubes need to be cut into small sections, and the small sections of paper tubes also need to be processed by end chamfering. In the prior art, long chemical fiber paper tubes are directly placed in an oven for drying, so that the glue therein is quickly dried and solidified, and then cut, chamfered, and processed. Since the glue in the paper tube solidifies at high temperature, cutting, chamfering, and other machining processes can easily cause the paper tube to crack and deform. Paper tubes with large cracks can be identified by the naked eye as waste products, while small cracks and deformations are often difficult to find. If they are used as qualified products, they are prone to problems such as broken wires during the spinning process. However, if the glue is not dried and directly cut, chamfered, and processed, the glue will be squeezed and cause the glue to overflow, affecting the product quality of the paper tube, and will also cause problems such as cracking in the later stage.
