Paper tube calender

Abstract

The invention discloses a paper tube calender, which comprises a supporting seat, a paper tube support arranged on the supporting seat, wherein the paper tube is supported on the paper tube support; the paper tube is provided with a central through hole penetrating along an axial direction; the calender further comprises a material-pressing component comprising a material tube seat and a calendering tube fixedly arranged on the material tube seat, wherein the material tube seat is fixedly arranged on the supporting seat; the calendering tube is provided with a through hole penetrating along an axial direction and is supplied for the paper tube to penetrate correspondingly and cooperatively, wherein the through hole and the paper tube are distributed along the same axial direction; the calendar further comprises a pressing mechanism capable of pressing the paper tube into the through hole along the axial direction; the pressing mechanism and the material-pressing component are respectively arranged on the supporting seat and located on two sides of the paper tube support. The paper tube calendar is simple in structure and convenient to use; and is adopted to calender the paper tube, thereby improving linearity and cylindricity of the paper tube.

Description

[0001] technical field [0002] The invention relates to a paper tube calender. [0003] Background technique [0004] In the prior art, the paper tube is generally cut by a spiral coiler, and the outer circumference of this type of paper tube will form a spiral pattern, resulting in a poor external appearance of the paper tube. When the tube is wound with some thinner materials such as film and copper foil, the winding layer close to the paper tube will easily form wrinkles, resulting in a large waste of materials. In order to solve this problem, the applicant covers a layer of paper on the outer peripheral surface of the paper tube, so that the spiral lines on the paper tube are covered. The paper needs to be adhered to the outer peripheral surface of the paper tube after gluing treatment, and a paper tube with a smooth outer peripheral surface can be obtained by waxing the surface. However, in the production process, the paper tube will be squeezed during the spiral c...

AI Technical Summary

Problems solved by technology

However, in the production process, the paper tube will be squeezed during the spiral coiler, coating, waxing, etc., resulting in the straightness and cylindricity of the paper tube not meeting the requirements, which is not conducive to the subsequent processing of the material. Winding requires calendering of the paper tube, so it is necessary to develop a special paper tube calender to achieve the above purpose
