Description

Technical Field

[0001] The utility model relates to the technical field of ceramic fiber paper production, in particular to a shearing device for ceramic fiber paper production. Background Art

[0002] Ceramic fiber paper is made of selected aluminum silicate ceramic fiber wool as the main raw material using a wet molding process. Based on the traditional process, the slag removal and drying processes have been improved. Its characteristics are no asbestos, uniform fiber distribution, white color, no stratification, less slag balls, flexible adjustment of bulk density according to the purpose, high strength, good elasticity, and strong machinability. Due to different use temperatures, it is divided into four materials: standard, high aluminum, and zirconium-containing ceramic fiber paper.

[0003] In the prior art, ceramic fiber paper is basically cut manually, which has the following problems: the length of the ceramic fiber paper is not well controlled and is prone to deviation; the cut edges are not particularly smooth, which affects the product quality; and the manual cutting processing effect is low.

[0004] For example, a shearing device for producing ceramic fiber paper disclosed in Chinese patent CN210910232U controls the linear module slide by a controller, and the linear module slide drives the slider to move in the slide slot, and the slider drives the photoelectric switch to move. When the distance between the photoelectric switch and the cutter meets the cutting length, the controller stops the linear module slide, and the cutting length can be accurately grasped, so that the cutting effect is better; according to the thickness requirement of the ceramic fiber paper, the controller starts the first cylinder, and the first cylinder drives the second concave plate to move, so that the distance between the pressure roller and the support roller can be adjusted, and at the same time, the threaded rod is rotated, and the threaded rod drives the pressure plate to move, so that the distance between the pressure plate and the workbench can be adjusted. The device is suitable for cutting ceramic fiber papers of different thicknesses; the ceramic fiber paper is placed between the support roller and the pressure roller, the controller starts the motor, the motor drives the support roller to rotate through the belt to drive the ceramic fiber paper to move, when the photoelectric switch senses the ceramic fiber paper, the photoelectric switch gives a signal to the controller, the controller stops the motor, the controller starts the second cylinder, the second cylinder drives the mounting plate to move downward, the mounting plate drives the cutter to move downward for shearing, when the cutter moves downward, the mounting plate drives the spring to move downward, the spring drives the rubber plate to move downward to press the ceramic fiber paper, so as to avoid the ceramic fiber paper from being offset during shearing, ensure the shearing effect of the cutter, and make the cut edge smooth.

[0005] However, in the prior art, during the shearing of ceramic fiber paper, the cutter usually does not have a limit buffer device, which can easily cause the cutter to move excessively during use, thereby causing damage to the cutter blade and affecting the subsequent cutting effect.

[0006] For this reason, we urgently need to provide a shearing device for producing ceramic fiber paper. Utility Model Content
