Description

Technical Field

[0001] The utility model relates to the field of leather manufacturing, in particular to a leather surface cleaning device. Background Art

[0002] The popular leather products on the market are divided into two categories: genuine leather and artificial leather. Synthetic leather and artificial leather are made of a textile base or a non-woven base, coated with polyurethane and treated with a special foaming process. They have a surface feel similar to genuine leather, but their air permeability, wear resistance and cold resistance are not as good as genuine leather. After going through multiple levels of production and processing, impurities will be attached to the surface of leather products. In order to improve the quality of leather products after production, the leather products need to be cleaned to remove surface impurities.

[0003] The prior art discloses a leather product surface cleaning device with application number CN202222401862.8. The device achieves the adjustment of the height of the cleaning brush by cooperating between the cleaning device body, the cleaning brush, the lifting device and the support rod, and utilizing the setting of the lifting device, thereby effectively solving the problem of different thicknesses of leather products. The circular rotation of the threaded rod drives the vertical lifting movement of the lifting block, so that the cleaning brush can be adjusted to a required height, thereby expanding the applicable range of the cleaning brush and improving the utilization rate of the cleaning brush. However, since the leather has a certain flexibility , and the device does not stretch and fix the leather, so when the cleaning brush is driven to rotate, wrinkles and shrinkage are likely to occur due to excessive friction. Although the device can perform rotational brushing on the leather, there is a certain gap between the two cleaning brushes, so that the middle part of the leather cannot be effectively brushed, and the device can only clean one side of the leather at a time, which is inefficient. Furthermore, the device requires multiple power mechanisms (water pumps, servo motors, and the instructions record a micro motor that drives the cleaning brush to rotate) to complete the cleaning process when working, which consumes a lot of electricity and has a high purchase cost for small and medium-sized enterprises.

Then the staff starts the motor, and the motor rotates to rotate the reciprocating screw rod, and the reciprocating screw rod rotates to move the threaded sleeve, and then drives the cleaning frame to move left and right through the fixed column. During the movement, the scraper can scrape off the stubborn impurities on the leather, and the first cleaning brush can move to repeatedly scrub the leather, and under the elastic force of the spring, the scraper and the first cleaning brush can provide a certain pre-pressure on the leather, so that the scrubbing effect is better;

[0020] 2. The utility model can drive the turntable to rotate while the reciprocating screw rotates. After the turntable rotates, it can drive the piston plate to move up and down through the linkage rod, so that the piston plate makes a piston movement in the piston cylinder. When the piston moves, water can be pumped to the piston cylinder through the water pumping pipe, and then sprayed out through the water spraying pipe and the nozzle. The sprayed water can rinse the leather. The sewage after rinsing flows downward, and the filter net can filter the sewage. The filtered water returns to the lower part of the inner body of the device, so that the water can be recycled. When the cleaning frame moves, it will drive the second cleaning brush to move back and forth. The second cleaning brush can brush impurities on the filter net to both sides to avoid large-scale clogging of the filter net and affect the filtering effect of the sewage. In summary, the present application has a wider cleaning surface and can clean both sides of the leather at the same time, thereby improving the cleaning effect and cleaning efficiency. In addition, the entire device does not need to be installed with multiple power mechanisms, so that the equipment consumes less power and has a lower purchase cost. The water consumption of the cleaning device is saved by using water circulation. By automatically cleaning the filter net, the filter net is not easy to be blocked, and the sewage filtering effect is better, thereby ensuring the efficiency of the water circulation.
