There are many types of sponge used in industrial production, such as foamed cotton, styling cotton, rubber cotton, and memory cotton.
Sponge is a porous material that has good water absorption and can be used to clean items.
The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are 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 (high-absorbent material, no obvious pores) and polyester.
The working principle of the special cutting machine for sponge: When the punching head acts on the workpiece through the die, the pressure in the working cylinder does not reach the rated pressure, and the pressure will increase as the time of contact (cutting into the workpiece) increases. The electromagnetic reversing valve receives the signal, the reversing valve reversing, and the punching head starts to reset; at this time, the pressure in the cylinder may not reach the set rated pressure value due to the limitation of the time of the pressure oil entering the cylinder; that is Say, the system pressure has not reached the design value, and the die cutting has been completed.
The special cutting machine for sponge is suitable for large and medium-sized sheet products such as automobile interiors, shoes, bags, handbags, mobile phone sets, seats, masks, plush toys, sponges, silk flowers, pearl cotton, EVA, blister packaging.
