Shearing mechanism for mask melt-blown cloth production

Abstract

The invention provides a shearing mechanism for mask melt-blown cloth production. The shearing mechanism comprises a bearing structure; a transmission belt is wound on the bearing structure, and an auxiliary structure is mounted on the right side of the transmission belt; a wheel body structure is arranged on the left side of the auxiliary structure; mounting structures are rotationally mounted at the front end and the rear end of the wheel body structure; a stretching structure is mounted on the outer wall of the wheel body structure in a sliding manner; a cleaning structure is mounted on the inner side of the stretching structure; and a shearing structure is slidably mounted in the wheel body structure. Generally, the shearing structure cuts off melt-blown cloth through heating and cutting, so that impurities adhere to the shearing structure after long-time use, and the problem that the shearing structure is difficult in cutting off the melt-blown cloth is caused; and the outer end surface of a cleaning plate is set to be of an inclined structure, so that the cleaning plate can better make contact with the shearing structure, and the purpose of cleaning the shearing structure is achieved.

Description

technical field [0001] The invention belongs to the technical field of mask production equipment, and more specifically relates to a cutting mechanism based on the production of mask melt-blown cloth. Background technique [0002] Melt-blown cloth, melt-blown cloth is the core material of the mask. The melt-blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths and other fields. [0003] Application number: In the patent of CN202021340498.3, the present invent...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a shearing mechanism based on the production of mask melt blown cloth to solve the problem that the existing melt blown cloth will have a certain Therefore, after long-term use, it will cause certain damage to the transmission belt. Usually, when the general melt-blown cloth is sent to the cutting position, the wrinkled position will inevitably be misaligned, and the truncated structure is for use. Heating and cutting will cut off the melt blown cloth, so that after long-term use, there will be sundries stuck on the cut-off structure, making it difficult to cut off the melt-blown cloth by the cut-off structure
