Slide seat of super calender and super calender

Abstract

The invention discloses a slide base of a super calender and the super calender and belongs to the technical field of papermaking equipment. The slide base is characterized in that a slide base body (1) is included and is provided with a connecting plate (3) used for being connected with a balance oil cylinder (10) and a calendering roller installing part (6) used for installing a calendering roller (11); the slide base body (1) is provided with a guiding part matched with a guiding mechanism. The calendering roller installing part is arranged on the slide base body of the super calender, the calendering roller can be installed on the slide base body, the connecting plate can be connected with the balance oil cylinder, and therefore gravity of the calendering roller can be balanced; the guiding part is used for guiding movement of the slide base body, and therefore the slide base body can keep moving linearly. The calendering roller of the super calender moves along a straight line, the movement space of the calendering roller slightly changes, and intermediate problems in the processing and operating process are few.

Description

technical field [0001] A sliding seat of a super calender and a super calender belong to the technical field of papermaking equipment, and in particular relate to a sliding seat of a super calender equipped with a calender roller and a paper guide roller, and the super calender. Background technique [0002] In paper production, the calender is the key equipment that ultimately determines the quality of the paper. For a long time, high-grade cultural papers such as coated paper, super-calendered paper and special industrial technical papers have been finished on existing super-calenders. [0003] In addition, the calender rolls of existing super calenders are all controlled by oil cylinders through swing arms to balance the gravity of the calender rolls. However, this structure makes the calender rolls do swinging motion in the vertical direction. During the process, the centers of the calender rolls are not in the same vertical plane, resulting in large changes in the spat...

Problems solved by technology

[0003] In addition, the calender rolls of existing super calenders are all controlled by oil cylinders through swing arms to balance the gravity of the calender rolls. However, this structure makes the calender rolls do swinging motion in the vertical direction. During the process, the centers of the calender rolls are not in the same vertical plane, resulting in large changes in the spatial position of the calender rolls, and many problems in the processing and operation process

Moreover, the diameter of the calender roller will change due to wear and tear during use, which will cause the relative position of the calender roller and the paper guide roller to change, which will affect the effect of calendering and paper guide.

[0004] Chinese utility model patent ZL201320297415.0 discloses a multi-roll calender. The balance oil cylinder balances the gravity of the calender rolls by handing over the swing arms on the frame row. The arc movement of the point seat, the movement space of the calender roll unit changes greatly, and the calender rolls are prone to collide with each other in the process of fast roll separation and fast roll closing, which will damage the calender roll, and the calender roll The relative position of the guide roll will change with the wear of the calender roll, which will affect the calendering of the paper web

This method of gravity balance using the swing arm type is a technical misunderstanding in the structural design of the super calender, and in the improvement of the super calender, it has not been able to solve the large movement space of the calender roller and the calender roller and guide paper. Technical solution to the problem that the relative position of the rollers will change
