Paper tube support shaped inner tube

Abstract

The invention discloses a sizing inner pipe for supporting a paper pipe. The sizing inner pipe comprises pipe wall arc plates, wherein the two sides of the arc surface of each pipe wall arc plate are respectively provided with an outer lip edge and an inner lip edge; the outer lip edges and the inner lip edges of the adjacent pipe wall arc plates are clamped, and the pipe wall arc plates are clamped so as to form an integrated round pipe; a group of vertically opposite pipe wall arc plates are provided with symmetric opposite handles, and the handles are fixed with the pipe wall arc plates through connecting plates; each pipe wall arc plate is in the shape of a 1 / 4 arc, and the connecting plates are fixed on the inner sides of a group of opposite inner lip edges; the connecting plates and the pipe wall arc plates are equal in length, the handles and the connecting plates are equal in length, and the two ends of the handles are provided with semicircle arc surfaces. The sizing inner pipe provided by the invention is used for supporting the paper pipe inside in a paper pipe rolling process, and after the rolling of the paper pipe is finished, the sizing inner pipe is disconnected and taken out from the paper pipe, so that the abrasion of the inner surface of the paper pipe is small, and the inner surface quality of the paper pipe is guaranteed.

Description

technical field [0001] The invention relates to a paper tube supporting shaped inner tube, which is an inner tube used to support the inside of the paper tube during the rolling process of a hollow paper tube to assist the setting of the paper tube, and belongs to the field of paper tube processing equipment. Background technique [0002] The paper tube is a round tube with a smooth surface made of paper rolls. It is used in many fields. Depending on the application field, the paper used in the paper tube is also different. Especially in the electronics industry, the requirements for various parameters of the paper tube are different. It is very high, not only special paper is used for rolling, but also the processing process is exquisite. The inner surface of the paper tube must be smooth, and the paper cannot be rubbed during the rolling process. In the traditional paper tube rolling system, there is a support tube inside the paper tube, and the paper is spirally wound on ...

AI Technical Summary

Problems solved by technology

In the traditional paper tube rolling system, there is a support tube inside the paper tube, and the paper is spirally wound on the surface of the support tube. Finally, after the paper is shaped into a paper tube, the support tube inside the paper tube is rotated and pushed out. During the process of pushing out the support tube, There is friction with the inner wall of the paper tube, and it has a certain abrasion effect on the paper on the inner wall of the paper tube. For industries such as the electronics industry that have high requirements for the paper tube, the performance reduction caused by such wear is not allowed
