[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0025] The present utility model aims to solve the problem that after crushing waste leather, there is no screening of the leather, and the leather and dust of different sizes are mixed together and directly discharged after crushing. The mixed leather waste cannot be directly used for production and needs secondary screening, which reduces production efficiency and brings inconvenience to subsequent production. Moreover, the leather of different sizes is stacked in the same position, which is inconvenient for workers to collect, inconvenient to match the needs of different products for leather, and causes unnecessary waste. It provides a Figures 1 - 3 recycling device for waste leather used in leather processing as shown in the figure, including two support legs 1. The top of the support legs 1 is fixedly connected with a recycling shell 12. The inner wall top of the recycling shell 12 is rotatably connected with two rotating columns 2. The outer surface of the rotating column 2 is fixedly connected with a rotating roller 21. The outer surface of the rotating roller 21 is fixedly connected with a plurality of crushing wheels 22, and the plurality of crushing wheels 22 are in clearance fit. When recycling the waste leather after crushing, rotate the rotating column 2. The rotation of the rotating column 2 drives the crushing wheels 22 to rotate. The clearance setting of the crushing wheels 22 can better crush the leather, and the crushed leather is classified according to the size of the leather.
[0026] Furthermore, at the bottom of the inner wall of the recycling shell 12, two first sieve meshes 3 and two second sieve meshes 31 are fixedly connected in a shape of an inverted V. The second sieve mesh 31 is located at the bottom of the first sieve mesh 3. The holes of the first sieve mesh 3 are larger than those of the second sieve mesh 31, and the length of the first sieve mesh 3 is longer than that of the second sieve mesh 31. In the middle of the inner wall of the recycling shell 12, a partition piece 32 is fixedly connected. On both sides of the recycling shell 12, discharge holes 4 are penetratingly opened. The first sieve mesh 3 and the second sieve mesh 31 respectively pass through the discharge holes 4. The crushed leather falls onto the partition piece 32, and the partition piece 32 separates the leather to both sides for screening. The first sieve mesh 3 and the second sieve mesh 31 screen the leather. The holes of the first sieve mesh 3 and the second sieve mesh 31 are of different sizes, and the crushed leather can be screened into different sizes, with better screening uniformity. During the screening process, internal impurity dust can be screened out, improving production efficiency and providing convenience for subsequent processing and production. The leather of different sizes moves downward after being screened by the first sieve mesh 3 and the second sieve mesh 31, and is classified and conveyed outside the recycling shell 12 through the discharge holes 4 on both sides, and is sorted to different positions according to size, which is convenient for the staff to collect separately, facilitating the accurate matching of the requirements of different products for leather fragments, avoiding the phenomenon of using large materials for small purposes or small materials for large purposes, thus reducing unnecessary waste and facilitating the maximization of resource utilization.
[0027] It should be noted that at the end parts of the two rotating columns 2, gears 13 are respectively fixedly connected. The gears 13 are located on one side of the outer wall of the recycling shell 12. On the other side of the outer wall of the recycling shell 12, a crushing motor 11 is fixedly connected. The rotating shaft of the crushing motor 11 is fixedly connected to the end part of one rotating column 2. The two gears 13 are meshed and connected. When crushing is required, the crushing motor 11 is turned on. The crushing motor 11 rotates to drive one rotating column 2 to rotate. The rotating column 2 rotates to drive one gear 13 to rotate. One gear 13 rotates to drive the other gear 13 to rotate, so that the other rotating column 2 rotates, achieving the reverse rotation of the two rotating columns 2, which is convenient for better crushing work.
[0028] It should also be noted that a plurality of crushing teeth 23 are fixedly connected to both sides of the inner wall of the recycling shell 12. The crushing teeth 23 are in clearance fit with the crushing wheels 22. The crushing teeth 23 can assist in crushing. The leather falling to both sides will be crushed by the crushing wheels 22 and the crushing teeth 23, and the leather crushing effect is good.
[0029] In the present utility model, the partition piece 32 is located on the top of the first sieve mesh 3, and the partition piece 32 is in movable contact with the first sieve mesh 3. When the first sieve mesh 3 vibrates, the vibration force will be transmitted to the partition piece 32, preventing the partition piece 32 from accumulating leather and avoiding leather accumulation.
[0030] It should be noted that a collection box 34 is inserted at the bottom of the recycling shell 12. The collection box 34 is located at the bottom of the second sieve 31. Both sides of the top of the first sieve 3 are fixedly connected with baffles 35. The dust is inside the recycling shell 12 and falls into the collection box 34 after screening. The collection box 34 collects the screened dust impurities, avoiding dust flying, improving the working environment and protecting the personal safety of the staff. After the recycling is completed, the staff can pull out the collection box 34 from the recycling shell 12 for cleaning, which is convenient for unified treatment. The baffle 35 can prevent the leather after screening by the first sieve 3 from falling from both sides, avoiding leather mixing and facilitating better classification.
[0031] In the present utility model, a plurality of vibration motors 33 are fixedly connected to the bottom of one side of the outer wall of the recycling shell 12. The rotating shafts of the vibration motors 33 are respectively fixedly connected to the exciters on the first sieve 3 and the second sieve 31. When the vibration motors 33 are turned on, the vibration motors 33 drive the exciters thereon to work, and the exciters cause the first sieve 3 and the second sieve 31 to screen the leather.
