Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather processing technology, and specifically relates to a leather surface cleaning device for leather product manufacturing. Background Technology
[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified, non-perishable material. Leather is composed of natural protein fibers tightly woven in three-dimensional space, with a special grain layer on its surface, possessing natural grain and luster, and a comfortable feel. During human evolution, people discovered that the sap of some plants or mineral oils has a certain tanning effect on leather. When raw hides are soaked in these sap, they become more breathable and rot-resistant, thus giving the hides physical and chemical properties such as softness, tear resistance, and flexural strength. Only at this stage does the leather truly possess the characteristics of leather products. This sap is called a tanning agent, and the surface cleaning process for leather is also essential.
[0003] Currently, the existing cleaning method involves workers using spray guns to clean the surface of leather products, resulting in poor cleaning effects and low cleaning efficiency. Directly rinsing with water involves rubbing the leather, which can cause damage. Furthermore, leather that has been rinsed with water is prone to mold growth due to incomplete drying, which is detrimental to leather storage and cannot meet the actual needs of leather production and processing.
[0004] Therefore, there is an urgent need for a leather surface cleaning device for leather product manufacturing. Utility Model Content

[0018] The working principle of this invention is as follows: leather is placed on a belt conveyor for transport. After the leather is transported to the area below the cleaning mechanism, the solenoid valve is opened and the liquid supply pump is started, allowing cleaning liquid to flow into the hose. The cleaning liquid enters the first roller and flows out from the outlet hole, wetting the sponge. Then, the output shaft of the first forward and reverse motor is controlled to rotate forward, driving the first threaded rod to rotate, causing the two first slide blocks to move from back to front. Simultaneously, the free ends of the two first electric push rods are stretched, lowering the first roller to brush the surface of the leather from back to front. Then, the output shaft of the first forward and reverse motor is controlled to rotate in reverse, brushing the surface of the leather from front to back a second time. This operation is repeated until the surface of the leather is clean. Finally, the two first electric push rods are controlled to retract. At the free end, the first roller is raised, and the leather is then conveyed to the bottom of the wiping mechanism using a belt conveyor. The output shaft of the second forward and reverse motor is reversed, driving the second threaded rod to rotate, causing the two second slides to move from back to front. Simultaneously, the two second electric push rods are controlled to stretch the free end, lowering the second roller and brushing the surface of the leather from back to front. Then, the output shaft of the second forward and reverse motor is controlled to rotate forward, brushing the surface of the leather from front to back a second time. This process is repeated until the surface of the leather is wiped clean, reducing moisture residue. After a period of use, the sponge on the outside of the first roller may become quite dirty, and the sponge on the outside of the second roller may absorb a lot of water. Both can be replaced to improve the cleaning and water absorption efficiency of the sponges.
[0019] The beneficial effects of this utility model are that it solves the problems of poor cleaning effect and low cleaning efficiency when cleaning manually; by setting up a cleaning mechanism, the surface of leather can be cleaned with good cleaning effect and high cleaning efficiency, and the sponge is soft and will not damage the leather surface; by setting up a wiping mechanism, the cleaning liquid adhering to the leather surface can be wiped off, reducing moisture residue and preventing mold; the sponge is fixed to the outside of each roller with Velcro, making it easy to replace.
