Description

TECHNICAL FIELD

[0001] The utility model relates to leather processing technical field especially relates to a leather cutting edge optimizer. BACKGROUND

[0002] Leather is often used as automotive interior materials, and leather is animal skin that has been denatured and is not easily perishable through physical and chemical processes such as unhairing and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space, and has a special grain layer on the surface, with natural grain and luster, and comfortable hand feeling.

[0003] In order to improve the appearance of leather and improve its quality, the edge part of the cut leather needs to be polished to reduce burrs and wrinkles and other defects, so as to achieve the effect of optimizing the cutting edge.

[0004] The patent document with the publication number CN220224199U discloses a process leather polishing and polishing device, which places the leather on the leather placing plate, and stretches the edge of the leather to be polished to the right side of the leather placing plate, adjusts the position of the adjusting block in the first limiting groove by rotating the lead screw, and then pushes the adjusting block against the adjusting block by the push plate. The value can be read by the scale, which can more accurately control the distance between the leather and the polishing disc, and then the polisher is started to press the leather and slide the leather placing plate back and forth, so as to polish the edge of the leather repeatedly, so as to better control the polishing pressure and avoid the phenomenon that the polishing degree is not the same when polishing the leather, reduce the rework and increase the polishing quality. When the leather is sliding back and forth on the leather placing plate during the polishing process, the two groups of opening rods always support the sealing strip between the two groups of opening rods, so that the sealing strip is kept sealed except the position between the two groups of opening rods, so that the air blower can only produce suction force between the two groups of opening rods, and the suction force is more concentrated, so that the suction capacity of the polishing debris is stronger, thereby reducing the scattering of debris in the air, reducing air pollution and ensuring the health of workers.

[0005] Although the above-mentioned process leather polishing and polishing device can solve the corresponding technical problems, when the leather is sliding back and forth on the leather placing plate during the polishing process, the edge of the leather is easy to be uneven or even offset, which not only increases the difficulty of subsequent polishing, but also reduces the optimization effect of the leather edge. Therefore, we propose a leather cutting edge optimizer. Utility model content
