Description

Technical Field

[0001] The invention relates to the technical field of microfiber leather production equipment, in particular to microcrystalline cellulose reinforced polyurethane microfiber leather production equipment. Background Art

[0002] Microcrystalline cellulose is a high molecular compound. It is made from natural cellulose through a special degree of cellulose hydrolysis and is named for its microcrystalline structure. Microcrystalline cellulose has good thickening and thickening effects and is widely used in the fields of chemical industry, food, pharmaceuticals, and synthetic leather. In the production of synthetic leather, the addition of microcrystalline cellulose can effectively enhance the thickening effect, making the viscosity of the synthetic leather slurry higher, reducing the possibility of dripping of the leather layer, and improving the overall performance of the leather layer. The polishing machine used in the production of microfiber leather is an important equipment, mainly used for polishing the surface of microfiber leather to improve the gloss, flatness and quality of the microfiber leather.

[0003] When the existing microcrystalline cellulose reinforced polyurethane microfiber leather production polishing equipment is in use, due to the inertia of the equipment and problems with the control system, the material roller will continue to rotate after the machine is stopped, which can easily cause the microfiber leather to accumulate and wrinkle, affecting the production efficiency and stability of the equipment. Moreover, the material roller installation structure is complex and requires a long shutdown time for disassembly and replacement, which reduces production efficiency. In addition, the polishing roller will withstand high-intensity friction impact loads during long-term use, which is prone to noise and vibration, affecting the stability of the equipment operation.
