[0030] The following will describe the implementation methods of the present invention in detail with reference to specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Example

[0032] like Figures 1 to 5 The present invention relates to a leather beating machine for producing flex-resistant leather, comprising: a frame 1; a rotating roller 2, wherein the rotating roller 2 is arranged above the frame 1 and is a hollow structure; a knife roller 3, wherein the knife roller 3 is arranged on one side above the rotating roller 2; a clamping assembly 4, wherein the clamping assembly 4 is arranged in the rotating roller 2, and the clamping assembly 4 comprises a clamping plate 41, a plurality of racks 42, a plurality of rotating gears 43 and a rotating rod 44, wherein the side wall of the rotating roller 2 is provided with an opening 21, the clamping plate 41 is arranged inside the opening 21, and each of the racks 42 is arranged inside the clamping plate 41, and each of the rotating gears 43 is respectively engaged with each of the racks 42, the rotating rod 44 is connected to each of the rotating gears 43, and both ends of the rotating rod 44 extend outwardly to protrude from the rotating roller 2, the knife roller 3, the rotating roller 2 and the rotating rod 44 are driven by different external driving components (not shown in the figure), and the rotation speed of the knife roller 3 is greater than the rotation speed of the rotating roller 2;

[0033] The present application does not impose any specific limitation on the number of racks 42 and rotating gears 43, which can be adjusted based on actual conditions.

[0034] By providing a rotating roller 2 with an opening 21 on the rotating roller 2, a clamping assembly 4 provided in the rotating roller 2 is used to clamp one end of the cowhide, so that the cowhide can rotate along with the rotating roller 2, and the hair on the surface of the cowhide is scraped off in cooperation with the knife roller 3. During the operation of the rotating roller 2, the cowhide does not require continuous energy consumption to be fixed, and the energy consumption of the equipment is low;

[0035] A driving assembly 5 is provided on one side of the knife roller 3. The driving assembly 5 includes a first driving wheel 51, a second driving wheel 52 and a driving belt 53. The first driving wheel 52 is sleeved on one end of the knife roller 3, and the second driving wheel 52 is provided below the first driving wheel 51. The driving belt 53 connects the first driving wheel 51 and the second driving wheel 52. The diameter of the first driving wheel 51 is smaller than that of the second driving wheel 52. The knife roller 3 adopts a scraper roller, which can be purchased on the market and is not described in detail here.

[0036] The second driving wheel 52 with a larger diameter, when driven by an external driving device, can drive the first driving wheel 51 to rotate at a higher speed through the belt 53. In the process of scraping hair from the surface of cowhide, the knife roller 3 has a high speed to ensure scraping efficiency.

[0037] It also includes a spacing adjustment component 6, which is provided at both ends of the rotating roller 2. The spacing adjustment component 6 includes a fixing ring 61, a sliding seat 62, a fixing seat 63, an adjusting rod 64 and a fixing plate 65. The fixing ring 61 is sleeved on the end of the rotating roller 2, the sliding seat 62 is provided below the fixing ring 61, the fixing seat 63 is provided below the sliding seat 62, and the fixing plate 65 is upright on the side of the frame 1 away from the knife roller 3. One end of the adjusting rod 64 is rotatably connected to one side of the sliding seat 62, and the other end of the adjusting rod 64 passes through the fixing plate 65. The adjusting rod 64 is threadedly connected to the fixing plate 65.

[0038] In the step of dehairing the cowhide, the thickness of each cowhide varies to a certain extent. When a lot of hair remains on the surface of the cowhide after scraping once, the adjusting rod 64 is rotated to push the sliding seat 62 to slide on the fixed seat 63 to reduce the distance between the rotating roller 2 and the knife roller 3, and the cowhide that has not been cleaned is scraped again to ensure that it is scraped cleanly.

[0039] The rotating roller 2 is provided with a rotating disk 22 at one end, and a locking rod 23 is provided below the rotating disk 22. One end of the locking rod 23 is rotatably connected to the frame 1, and the other end of the locking rod 1 is provided with an adjusting gear 24; the rotating roller 2 is rotated by the rotation of the rotating disk 22, and the rotating disk 22 is connected to the external driving gear 25 by a chain 26, and the adjusting gear 24 is meshed with the outer side of the chain 26, and the adjusting gear 24 can be moved away from the chain 26 by rotating the locking rod 23, which is convenient for direct replacement. At the same time, the setting of the locking rod 23 and the adjusting gear 24 is also used to adjust the tightness of the chain 26 when the spacing adjustment assembly 6 adjusts the position of the rotating roller 2. The connection between the locking rod 23 and the frame 1 is bolted. Loosening the bolt allows the locking rod 23 to rotate, and tightening the locking screw fixes the locking rod 23. This is a conventional technical means and will not be repeated here.

[0040] The material guide assembly 7 further includes a material guide assembly 7, which includes a connecting frame 71 and a material guide plate 72. The material guide plate 72 is arranged on the side of the rotating roller 2 away from the knife roller 3, and the connecting frame 71 is arranged on both sides of the bottom of the material guide plate 72. The material guide plate 72 is provided with a plurality of drainage holes (not shown in the figure); the setting of the material guide assembly 7 is convenient for placing cowhide for material guidance, and the cowhide after being scalded with hot water is more convenient for scraping hair, and the setting of the drainage holes can timely drain out the accumulated water on the material guide plate 72.

[0041] How it works:

[0042] Place one end of the cowhide at the opening of the rotating roller, drive the rotating rod to rotate, drive the clamping plate to fix one end of the cowhide, and then the rotating roller and the guide roller start to rotate to scrape the hair on the cowhide. After the rotating roller rotates one circle, the scraping is completed, and the rotating rod rotates in the opposite direction, driving the clamping plate to loosen one end of the cowhide.

[0043] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
