Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of abrasion components for water-based leather abrasion machines, and more particularly to an abrasion component for water-based leather abrasion machines. Background Technology
[0002] A water-based leather polishing machine is a mechanical device specifically designed for treating the surface of water-based synthetic leather. It is mainly used to grind and polish leather materials to improve their surface smoothness, softness, and aesthetics. This equipment removes defects, burrs, or uneven coatings from the surface of the leather material through mechanical grinding.
[0003] The leather grinding assembly is the core working component of a water-based leather grinding machine. It consists of a grinding head, a transmission mechanism, a pressure regulating device, and a thickness control system. The grinding head grinds the leather surface using a high-speed rotating abrasive belt or wheel. The pressure regulating device and the thickness control system work together to ensure the uniformity and stability of the grinding process. The leather grinding assembly needs to dynamically adjust the grinding parameters according to the thickness, hardness, and processing requirements of the leather material to ensure processing accuracy and consistency. Its performance directly affects the grinding effect, thus placing high demands on the structural design, material selection, and control precision of the assembly. Existing leather grinding assemblies have avoided the problem of uneven leather thickness to some extent through the thickness control system, but their grinding efficiency is still significantly insufficient. During high-speed operation, the grinding head is prone to fluctuations in grinding force due to uneven pressure distribution or abrasive belt wear, which in turn affects the uniformity of surface treatment. Due to the lack of real-time monitoring and dynamic compensation of the leather surface condition, it is difficult to meet the processing requirements of high precision and high efficiency. This problem makes it impossible for existing devices to achieve efficient and fine treatment of the leather surface while ensuring thickness consistency, thus restricting the overall performance improvement of water-based leather grinding machines.

The protruding plate 202 is fixed to the left side of the leather polishing machine frame 1, and its multiple spray nozzles 203 on the right side can precisely aim at the polishing area, atomizing and spraying the dust suppression liquid. While covering the polishing area, it controls the amount of liquid used, effectively reducing dust concentration and inhibiting dust diffusion, while also preventing the leather from becoming damp due to excessive liquid spraying. The safety protector 204 on the top of the circular plate 201 can block external dust and debris, protecting the internal fan 205 and motor 206. The motor 206 is stably installed by the fixing block 207, and its output end drives the fan 205 to rotate, accelerating the diffusion of atomized liquid and improving dust settling efficiency. The whole mechanism, through stable structural design, precise spray control and efficient atomization diffusion, significantly suppresses dust flying during the leather grinding process, improves the cleanliness of the working environment, reduces the wear of dust on machine parts, extends the service life of equipment, and ensures production safety and reliability.

[0040] Working principle: Start motor 4, which is fixed on fixed plate 3. Stable installation ensures smooth power output. The power of motor 4 is transmitted to connecting column 6 through the output end. Connecting column 6, made of high-strength material, withstands tension and transmits the power to storage column 7. Storage column 7 then starts to rotate, realizing the automatic release and retraction of the sanding belt. The sanding belt state is adjusted according to different leather processing needs. After the power transmission is completed, the leather enters the sanding stage. The leather moves along the guide rail groove 8 and slide rail 9 inside the outer frame 1 of the sanding machine. Fixed block 10, connecting column 11 and circular fixed column 12 work together to drive the sanding belt to move smoothly, reduce friction and wear, and extend the service life of the sanding belt. The abrasive material on the surface of the sanding plate 13 is sanded by the sanding belt to polish the imperfections and unevenness on the surface of the leather, making the leather smoother and more uniform, and improving the quality of the finished product.
[0041] Furthermore, confirm the secure connection between the fixed circular plate 201 and the outer frame 1 of the leather grinding machine, check whether the bottom of the outer wall is firmly fixed to the top left side of the outer frame 1 of the leather grinding machine, and ensure that the entire spraying system will not loosen or shift due to machine vibration during subsequent operation. Check whether the protruding plate 202 is properly fixed to the left side of the outer wall of the outer frame 1 of the leather grinding machine to ensure accurate spraying direction and effective spraying of dust-proof liquid toward the leather grinding area. Inject an appropriate amount of dust-proof liquid into the spraying system, and check whether the multiple spray heads 203 are installed in place and without blockage to ensure that the dust-proof liquid can be smoothly atomized and accurately sprayed onto the leather grinding area to achieve the best dust suppression effect and avoid excessive liquid spraying that could cause the leather to become damp. Start the motor 206, and the output end drives the fan 205 to rotate. Observe the operation of the fan 205 to ensure that it works normally within the safety protector 204, spreading the atomized liquid sprayed from the spray head 203 to improve dust settling efficiency. Check whether the fixed block 207 is secure to ensure that the motor 206 will not vibrate or shift when running at high speed, and ensure the safety and reliability of the entire spraying mechanism.
