[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 3 as well as Figure 6 The diagram shown is a structural schematic of the donkey hide pre-processing and cleaning machine in this embodiment. The cleaning machine includes a cleaning table 1 on which a donkey hide body 21 is placed. Two movable chutes 2 are symmetrically arranged on the top of the cleaning table 1. A sliding seat 3 is slidably installed in one of the chutes 2, and a movable seat 4 is slidably installed in the other chutes 2. A movable frame 5 is fixedly connected to the sliding seat 3 and the movable seat 4. A connecting plate 6 is vertically mounted within the movable frame 5, and a cleaning device is fixedly connected to the bottom of the connecting plate 6. The scraper 7 and the connecting plate 6 are equipped with a mounting branch pipe 8, which is equipped with multiple nozzles 9. During the use of the cleaning machine, since the movable frame 5 can slide horizontally on the cleaning table 1, the cleaning scraper 7, which can move up and down, is brought closer to the table surface, so that the cleaning scraper 7 presses against the donkey hide body 21 on the table surface. Then, the movable frame 5 drives the cleaning scraper 7 to move together, thereby using the cleaning scraper 7 to scrape off the oily dirt contained in the donkey hide surface. At the same time, water is passed into the mounting branch pipe 8, and the multiple nozzles 9 are used to rinse the scraped dirt.

[0028] In this embodiment, the movable frame 5 is inverted U-shaped. A support plate 14 is fixedly connected to one side of the movable frame 5. Two symmetrically distributed electric push rods 15 are installed at the bottom of the support plate 14. The output end of the electric push rod 15 is fixedly connected to a mounting support plate 10. A drive shaft 11 is arranged between the two mounting support plates 10 through a bearing. A cleaning roller 12 is coaxially arranged on the surface of the drive shaft 11. A brush 13 is arranged on the outer surface of the cleaning roller 12. A support frame is detachably installed on one of the mounting support plates 10. A drive motor is installed on the support frame, and the output end of the drive motor is fixedly connected to one end of the drive shaft 11. While scraping away greasy dirt, the drive motor is controlled to drive the transmission shaft 11, causing the cleaning roller 12 and brush 13 to rotate together with the transmission shaft 11. The brush 13 is lowered to get close to the surface of the donkey hide, and the cleaning roller 12 with the brush 13 is used to further clean the surface of the donkey hide, removing the sticky and residual greasy dirt. This not only cleans the dust and impurities on the surface of the donkey hide, but also thoroughly scrapes and rinses away the greasy dirt on the surface, avoiding the residue of greasy dirt, improving the cleaning effect of the donkey hide, and ensuring the quality of the donkey hide-made donkey-hide gelatin.

[0029] like Figure 1as well as Figure 2 As shown, in this embodiment, another movable slide 2 has a screw 16 installed inside via a bearing, and the screw 16 is threadedly connected to the movable seat 4. One end of the screw 16 extends outside the cleaning table 1, and a mounting bracket 17 is fixedly connected to the cleaning table 1. The output end of the rotary motor 18 is fixedly connected to one end of the screw 16, and the rotary motor 18 is fixed on the mounting bracket 17. In order to provide driving force for the movable frame 5, the rotary motor 18 is controlled, and the output end of the rotary motor 18 drives the screw 16 to rotate. At the same time, by utilizing the threaded engagement between the screw 16 and the movable seat 4, the rotating screw 16 causes the movable seat 4 to slide horizontally, and under the guidance of the sliding seat 3, the movable frame 5 can move freely on the cleaning table 1.

[0030] like Figure 4 as well as Figure 5 As shown, in this embodiment, two sets of fixing frames 20 are fixedly connected to the washing table 1. The donkey hide body 21 is located between the two sets of fixing frames 20. A threaded ring 22 is provided through the fixing frame 20. A threaded limiting rod 23 is threadedly connected to the inner surface of the threaded ring 22. One end of the threaded limiting rod 23 is rotatably connected to a clamping plate 24. The other end of the threaded limiting rod 23 is fixedly connected to an adjusting handle 25, and the adjusting handle 25 is located above the fixing frame 20. When the donkey hide body 21 is positioned between the two fixing frames 20, the threaded engagement between the threaded ring 22 and the threaded limiting rod 23 is used to rotate the adjusting handle 25. By rotating the threaded limiting rod 23, the clamping plate 24 is driven to move closer to the donkey hide surface, so that the clamping plates 24 at the four corners clamp the donkey hide respectively, so as to ensure that the donkey hide remains stable during the washing process, which is more conducive to the washing of the donkey hide.

[0031] like Figure 2 As shown, in this embodiment, the inner wall of the movable frame 5 has two guide grooves 26, and the two guide grooves 26 are symmetrically distributed. Sliding blocks 27 are slidably installed inside the two guide grooves 26. The connecting plate 6 is fixed between the two sliding blocks 27. By utilizing the sliding cooperation between the guide grooves 26 and the sliding blocks 27, the moving connecting plate 6 can be guided to ensure that the connecting plate 6 moves up and down stably.

[0032] It is worth noting that in this embodiment, one end of the installation branch pipe 8 is connected to a water guide pipe, and one end of the water guide pipe can be connected to a water supply device. The water supply device can guide water into the installation branch pipe 8 through the water guide pipe. Two symmetrical telescopic cylinders 19 are installed on the movable frame 5, and one end of the telescopic cylinder 19 is fixedly connected to the connecting plate 6.

[0033] 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.
