Description

Technical Field

[0001] This utility model belongs to the field of skin resurfacing technology, and in particular relates to a vertical skin resurfacing machine. Background Technology

[0002] The technology of leather polishing machines can be traced back to the early development stage of the leather processing industry. With the growth in demand for leather products and the continuous advancement of processing technology, leather polishing machines have gradually evolved from simple manual tools into automated and intelligent mechanical equipment. The working principle of leather polishing machines is mainly based on the rotating grinding action of grinding wheels or abrasive wheels. When the grinding wheel or abrasive wheel rotates at high speed, the diamond particles or abrasives on its surface will scrape and polish the leather surface, thereby removing impurities, burrs and uneven parts from the leather surface, making the leather surface smooth and delicate.

[0003] Traditional leather polishing machines are often designed with standardized polishing modes and parameter settings. Due to the differences in the physical properties of leather, such as thickness and hardness, traditional polishing machines often cannot quickly and accurately adjust the polishing degree according to the specific properties of the leather. In actual operation, workers often need to rely on experience and feel to judge and adjust the polishing degree, which is not only inefficient but also makes it difficult to ensure the consistency and stability of polishing quality, and can easily cause unnecessary damage to the leather. Therefore, we have proposed a vertical leather polishing machine. Utility Model Content

[0004] The purpose of this invention is to provide a vertical leather polishing machine. Through the adjustment mechanism and centering mechanism, it solves the problem that traditional leather polishing machines often adopt standardized polishing modes and parameter settings in their design. Due to the differences in the physical properties of leather, such as thickness and hardness, traditional leather polishing machines often cannot quickly and accurately adjust the polishing degree according to the specific properties of the leather. In actual operation, workers often need to rely on experience and feel to judge and adjust the polishing degree, which is not only inefficient but also makes it difficult to ensure the consistency and stability of polishing quality, and can easily cause unnecessary damage to the leather.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vertical skin resurfacing machine, comprising a frame, a conveyor belt fixedly connected to the outer wall of the frame, a lifting and fixing frame fixedly connected to the outer wall of the frame, a transmission rod fixing block fixedly connected to the bottom outer wall of the frame, a first motor slidably connected to the outer wall of the lifting and fixing frame, a rotating shaft fixedly connected to the bottom output shaft of the first motor via a coupling, an adjustment mechanism provided on the outer wall of the frame, the adjustment mechanism including a lifting and fixing block, a threaded tube limiting block fixedly connected to the top inner wall of the lifting and fixing block, the lifting and fixing block being fixedly connected to the frame, and a threaded tube rotatably connected to the inner wall of the lifting and fixing block. The inner wall of the threaded tube is threaded with a lifting threaded rod. A worm gear is fixedly connected to the bottom outer wall of the threaded tube. A lifting block is fixedly connected to the top outer wall of the lifting threaded rod. A grinding roller is rotatably connected to the inner wall of the lifting block. A transmission rod is rotatably connected to the inner wall of the transmission rod fixing block. Worms are fixedly connected to the left and right outer walls of the transmission rod. A gear is fixedly connected to the central shaft of the outer wall of the transmission rod. A second motor is fixedly connected to the bottom outer wall of the frame. A second rotating shaft is fixedly connected to the bottom output shaft of the second motor through a coupling. A transmission gear is fixedly connected to the outer wall of the second rotating shaft. A centering mechanism is provided on the outer wall of the frame.

[0007] The above technical solution, by setting an adjustment mechanism, allows the grinding roller to be used with leather of different materials and thicknesses, greatly improving the versatility of the device.

[0008] Furthermore, the centering mechanism includes a centering fixing frame, which is fixedly connected to the frame, the worm gear meshes with the worm wheel, the transmission gear meshes with the gear, the grinding roller is fixedly connected to the rotating shaft, the threaded tube limiting block is slidably connected to the threaded tube, and a bidirectional threaded rod is rotatably connected to the top inner wall of the centering fixing frame.

[0009] Through the above technical solution, by setting up a centering mechanism, when the leather is placed on the top of the guide rod, the centering mechanism will center the leather on the guide rod, so that the leather is polished more evenly and thoroughly.

[0010] Furthermore, a third motor is fixedly connected to the outer wall of the centering fixing frame, a guide rod is fixedly connected to the inside of the centering fixing frame, and limit frames are fixedly connected to the top outer walls of the left and right sides of the centering fixing frame.

[0011] Through the above technical solution, by setting a limiting frame, the limiting block slides on the outer wall of the limiting frame, so that the limiting block can run smoothly and the leather can be accurately centered.

[0012] Furthermore, the bottom output shaft of the third motor is fixedly connected to a rotating shaft three via a coupling, and centering blocks are slidably connected to the left and right outer walls of the guide rod, and a limit groove is formed on the inner wall of the limit frame.

[0013] With the above technical solution, by setting a limiting groove, when the centering mechanism is started, the limiting block slides on the outer wall of the limiting groove. The design of the limiting groove avoids the moving block from moving excessively on the bidirectional threaded rod.

[0014] Furthermore, a transmission gear two is fixedly connected to the outer wall of the rotating shaft three, and a moving block is fixedly connected to the top outer wall of the centering block.

[0015] The above technical solution involves setting up a moving block, which drives the centering block to move via the rotation of a bidirectional threaded rod. The centering block then performs centering processing on the leather, enabling the centering mechanism to operate stably.

[0016] Furthermore, the left and right outer walls of the movable block are fixedly connected to limit blocks, the limit blocks are slidably connected to the limit grooves, and the movable block is threadedly connected to the bidirectional threaded rod.

[0017] Through the above technical solution, by setting a bidirectional threaded rod, the third motor is started and drives the centering mechanism to run, so that the bidirectional threaded rod drives the moving block to move, and the moving block drives a series of accessories to work together stably.

[0018] Furthermore, a second gear is fixedly connected to the outer wall of the right end of the bidirectional threaded rod, and the second gear meshes with the second transmission gear.

[0019] Through the above technical solution, by setting up a second transmission gear, the power of the third motor is transmitted to the bidirectional threaded rod through the second transmission gear, so that the bidirectional threaded rod can operate efficiently.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model incorporates an adjustment mechanism. When leather is conveyed via a conveyor belt, it reaches the bottom of the polishing roller. A first motor drives the polishing roller to rotate, and a second motor activates a series of accessories that work together to raise and lower the lifting threaded rod inside the threaded tube. This lifting threaded rod, in turn, causes the polishing roller to move up and down. By precisely adjusting the height of the polishing roller, it can accommodate leathers of different materials or thicknesses, preventing over-polishing. This mechanism allows for flexible height adjustment of the polishing roller based on the material or thickness of the leather, ensuring that the polishing effect is neither excessive nor insufficient, perfectly adapting to the needs of various leathers. This system effectively avoids unnecessary damage to the leather. This precise polishing control not only protects the original texture of the leather but also extends its service life, resulting in a more beautiful and durable final product, greatly increasing the flexibility and versatility of the device.

[0022] 2. This utility model incorporates a centering mechanism. The leather is placed on top of the guide rod, and a third motor is activated. This motor drives a series of components to rotate, causing the bidirectional threaded rod to rotate. The bidirectional threaded rod then moves the moving block, which in turn moves the limiting block to slide on the outer wall of the limiting groove. The moving block then moves the centering block to slide on the outer wall of the guide rod, thus centering the leather. This prevents the leather from shifting during conveyor belt transport, which would otherwise result in incomplete polishing. This high-precision centering operation effectively prevents the leather from shifting during conveyor belt transport, ensuring that the leather receives uniform and comprehensive polishing treatment, thereby significantly improving polishing quality and the consistency of the finished product.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Limiting frames 304 are fixedly connected to the top outer walls of the left and right sides of the centering fixing frame 301. By setting the limiting frames 304, the design of the limiting frames 304 ensures that the moving block 307 remains stable when moving on the bidirectional threaded rod 306, avoiding external forces from affecting the movement of the moving block 307. The bottom output shaft of the third motor 312 is fixedly connected via a coupling. There is a rotating shaft 311, and centering blocks 303 are slidably connected to the left and right outer walls of the guide rod 302. The inner wall of the limiting frame 304 has a limiting groove 305. Through the design of the limiting groove 305, the moving block 307 can slide stably on the outer wall of the limiting groove 305, avoiding excessive movement of the moving block 307 on the bidirectional threaded rod 306. The outer wall of the rotating shaft 311 is fixedly connected to the transmission gear 310, and the top outer wall of the centering block 303 is fixedly connected to the moving block 307.
