Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to an adjustable leatherware polishing device. Background Technique

[0002] Leatherware, as the name implies, refers to various daily necessities and ornaments made of animal leather as the main raw material through a series of processing techniques. Polishing is a key process in leatherware production. Its purpose is to optimize the surface state of the leather, lay a foundation for subsequent processes such as dyeing, edge sealing, and decoration, and at the same time improve the durability and beauty of leatherware. The current adjustable leatherware polishing device first limits the leatherware and then polishes it through a polishing roller. If there are unevenness or foreign objects on the contact surface between the fixture and the leatherware after the leatherware is limited, it may cause uneven stress when the leatherware is clamped, resulting in local undulations. When the polishing roller polishes this area, it may cause excessive wear on the leather surface, or even damage or tearing. Content of the Utility Model

A polishing roller 5 is rotatably connected to one side of the movable block 4, and a first motor 6 for driving the polishing roller 5 is mounted on one side of the movable block 4. A first cylinder 7 connected to the top of the vertical plate 2 and the top of the movable block 4 is connected to the top of the vertical plate 2. A horizontal plate 8 is provided on one side of the vertical plate 2, and a first support 9 with a "U"-shaped cross-section is provided on one side of the horizontal plate 8. A second support 10 is slidably disposed at the bottom of the first support 9, and a rotating rod 11 is rotatably connected to the surface of the second support 10. Furthermore, a pressure roller 12 is connected to one side of the rotating rod 11; a sleeve 13 is connected to the top of the first bracket 9, and a support rod 14 connected to the top of the second bracket 10 is movably sleeved inside the sleeve 13. After the leather goods are positioned at the top of the worktable 1, the grinding roller 5 can be moved to the surface of the leather goods by the operation of the first cylinder 7, and the support rod 14 can be moved so that the pressure roller 12 below the support rod 14 can be moved to the surface of the leather goods. When the first screw 22 rotates, the vertical plate 2 can drive the grinding roller 5 and the pressure roller 12 to move. The uneven surface of the leather goods can be flattened by the pressure roller 12 first, and then the surface can be polished by the grinding roller 5.

[0031] Furthermore, the inner wall of the sleeve 13 is symmetrically provided with a sliding groove 15, and a slider 16 connected to the support rod 14 is slidably connected inside the sliding groove 15.
