Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sponge processing, and more specifically to a sponge flat cutting machine with smooth incisions. Background Art
[0002] The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material without obvious pores) and polyester.
[0003] In the existing sponge cutting process, the sponge is mostly cut directly by a blade. During the up and down cutting process of the blade, the cross section of the sponge will rest against the surface of the blade. The oxide layer or impurities generated during the long-term working process of the blade will cause the friction coefficient between the blade and the cross section to increase. Therefore, the friction force generated between the blade and the cross section during the return process of the blade may cause the position of the sponge to shift or tilt, thereby causing an uneven cut on the sponge.
