Description

Technical Field

[0001] This utility model relates to the field of leather polishing technology, specifically a small leather polishing machine. Background Technology

[0002] The mini leather polishing machine is a benchtop power tool designed for details such as handmade leather goods, belt edges, and wallets. It uses an adjustable speed motor to drive a cloth wheel or wool wheel, and with the help of polishing wax, it rubs and heats the leather surface to quickly seal the fibers and enhance the luster. It can also change different grit heads to complete multiple processes such as deburring, fine trimming, and mirror polishing. It is small in size and low in noise, making it suitable for use on a workbench in a studio. After a single polishing of the leather is completed, the polishing pad needs to be cleaned to prevent particles from adhering to the surface of the polishing pad and to ensure the polishing effect of the next polishing. Small polishing machines are generally not equipped with cleaning devices, and the polishing pad needs to be disassembled for cleaning, resulting in low cleaning efficiency. Therefore, a small leather polishing machine is proposed to address the above problems. Utility Model Content

[0016] Please see Figure 1-6 This utility model provides a technical solution: A small leather polishing machine includes a drive motor 1 and a polishing disc 2 for polishing leather. The polishing disc 2 is fixedly connected to the top of the main shaft of the drive motor 1. A control component 3 is fixedly connected to the top of the housing of the drive motor 1. A protective component 5 is installed at the lower end of the polishing disc 2. An electric lifting component 4 is installed at the lower end of the protective component 5. A first one-way valve 7 and a second one-way valve 8 with a filter structure are installed in the middle of the lower end of the protective component 5. The lower end of the first one-way valve 7 is fixedly connected to a water storage tank 9. A piston plate 11 is slidably connected inside the water storage tank 9 through a telescopic spring 10. A guide rod 12 is fixedly connected to the middle of the other end of the piston plate 11. The top end of the guide rod 12 is in close contact with a limit block 6.

[0017] As a further implementation of this solution, the control component 3 includes a vertical plate 31, one end of which is fixedly connected to a toothed plate 32. With the above arrangement, during the process of the protective bottom shell 51 moving to the lower end of the polishing disc 2, the toothed plate 32 can engage with the teeth 53, and the rotating shell 52 can be rotated out of the protective bottom shell 51, thereby achieving a complete seal on the polishing disc 2. As a further implementation of this solution, the protective component 5 includes a protective base shell 51, a rotating shell 52 rotatably connected to the inner side of the protective base shell 51, and a quarter-circularly distributed tooth 53 fixedly connected to one side of the rotating shell 52. With the above arrangement, a complete protective ring can be formed after the rotating shell 52 rotates out from the outside of the protective base shell 51. As a further implementation of this solution, the tooth 53 is set on the outside of the protective bottom shell 51. The tooth 53 is adapted to the tooth plate 32. There are two rotating shells 52, and the two rotating shells 52 correspond one-to-one with the tooth plate 32. With the above arrangement, the rotating shell 52 can be driven to rotate out of the protective bottom shell 51 stably. As a further implementation of this solution, the electric lifting assembly 4 includes a fixed column housing 41, and a lifting rod 42 is connected inside the fixed column housing 41 through a lifting unit 43; the lifting rod 42 includes a vertical rod 421, and a water storage cavity 424 is opened inside the top of the vertical rod 421. A round hole 423 and a square hole 422 are opened on both sides of the water storage cavity 424 respectively. With the above configuration, the protective assembly 5 can be moved stably to the lower end of the polishing disc 2 and the cleaning fluid can be transferred to the lower end of the polishing disc 2. As a further implementation of this solution, the vertical rod 421 is slidably connected to the upper end of the fixed column shell 41, the square hole 422 is connected to one end of the water storage shell 9, and the round hole 423 is slidably connected to the guide rod 12 through the sealing ring. Through the above settings, the sealing of the connection between the water storage shell 9 and the water storage cavity 424 can be guaranteed, and the stability of the movement of the guide rod 12 can be improved. As a further implementation of this solution, the included angle between the guide rod 12 and the piston plate 11 is 90°. The end of the guide rod 12 located outside the vertical rod 421 is arc-shaped. The upper end of the limiting block 6 is provided with an inclined surface, and the limiting block 6 is fixedly connected to the upper end of the fixed column shell 41 by screws. Through the above settings, the stability of the device operation is further improved during the overall operation of the device.

[0018] Work process: During the operation of the equipment, it is powered by an external power source. After the power is turned on, the drive motor 1 is controlled to drive the polishing disc 2 to rotate. Then, the rotating polishing disc 2 comes into contact with the leather to achieve the leather polishing process. After polishing, the lifting unit 43 controls the protective base shell 51 to move to the lower end of the polishing disc 2. When the lifting unit 43 reaches its maximum stroke, the teeth 53 on the outer side of the rotating shell 52 contact the toothed plate 32, and the whole unit rotates to the upper end of the polishing disc 2, thus completely sealing the polishing disc 2 with the help of the protective base shell 51. During this process, the guide rod 12 separates from the limit block 6, the telescopic spring 10 pushes the piston plate 11 to move, and pushes the cleaning fluid inside the water storage tank 9 and the water storage cavity 424 through the second one-way valve 8 to the bottom end of the protective base shell 51. At this time, the polishing disc 2 is rotated again, so that it rotates inside the protective component 5 and comes into contact with the cleaning fluid to complete the cleaning. After the cleaning is completed, the lifting unit 43 is controlled to drive the lifting rod 42 to reset. After the reset is completed, the protective component 5 is completely restored to the initial state, and the guide rod 12 contacts the limit block 6 again. At this time, the cleaning fluid at the bottom of the protective bottom shell 51 flows back into the water storage shell 9 through the first one-way valve 7 and filters the impurities in the cleaning fluid to ensure the cleanliness of the cleaning fluid in the next cleaning process of the polishing disc 2.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
