[0002] The tumbling drum is a key piece of equipment in leather tanning. It accelerates the softening of leather through rotation, kneading, and mechanical impact, resulting in a uniform fiber structure, promoting dye penetration, and improving the softness and quality of the finished product. The protective structure of the tumbling drum, through reinforced chamber, cushioning and shock absorption, and sealing design, prevents damage and leakage during high-speed operation, ensuring operational safety, extending equipment life, and ensuring uniform and stable softening of the leather.
[0003] Some stainless steel tumbling drums may cause leather to be thrown out during rotation due to incomplete sealing, which could injure nearby operators. Existing technology involves setting up a specific protective net around the drum so that the protective net can slide during loading and unloading.
[0004] In existing technologies, protective nets slide on the inner wall of a fixed structure and are fixed around the perimeter with bolts. This makes them difficult to disassemble, resulting in the accumulation of a large amount of dust, which is inconvenient for cleaning. The accumulated dust affects the protective performance, breeds bacteria, accelerates structural corrosion, is difficult to clean and can damage equipment, increase maintenance costs, and block ventilation, causing malfunctions. Therefore, a stainless steel drop-soft rotating drum protective structure is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a stainless steel drop-resistant rotating drum protective structure, comprising a fence 1 and four fixing boxes 5. Two fixing boxes 5 are externally fixedly connected to the inner wall of the fence 1 to assist in the disassembly and installation of the protective net. Another fixing box 5 is slidably connected to the outside of each fixing box 5, and the position of the two fixing boxes 5 is used to fix the position of the protective net and the fence 1. A mesh plate 4 is fixedly connected to the outside of the two fixing boxes 5, so that the position of the fixing boxes 5 drives the position of the mesh plate 4. A positioning box 6 is fixedly connected to the inner wall of each fixing box 5, and a semi-circular block 7 is slidably connected to the inner wall of the positioning box 6, which restricts the position of the semi-circular block 7. A toggle lever 20 is fixedly connected to the outside of the semi-circular block 7; pressing the toggle lever 20 causes the semi-circular block 7 to change angle.
[0034] A reset assembly is fixedly connected to the outside of the actuating lever 20 to help reset the lever 20 when its position changes. The reset assembly includes a rotating shaft 10, which is rotatably connected to the inner wall of the fixed box 5, and the fixed box 5 fixes the position of the rotating shaft 10. A spring 9 is fixedly connected to the inner wall of the rotating shaft 10, and the rotating shaft 10 fixes one end of the spring 9. A traction rod 8 is fixedly connected to the other end of the spring 9, and the position change of the traction rod 8 causes the spring 9 to deform. The other end of the traction rod 8 is slidably connected to the inner wall of the actuating lever 20, and the position change of the traction rod 8 causes the actuating lever 20 to change position. A sliding window 19 is provided on the inner wall of the fixed box 5, and the outside of the actuating lever 20 is slidably connected to the inner wall of the sliding window 19, which limits the sliding position of the actuating lever 20.
[0035] Reference Figure 2 and Figure 4 Two drive rods 2 are installed on the inner wall of the fence 1, and the fence 1 fixes the position of the two drive rods 2. A drum body 3 is fixedly connected to the adjacent end of the two drive rods 2, which drives the drum body 3 to rotate. A motor 11 is installed on the inner wall of the drum body 3, which fixes the installation position of the motor 11 and serves as the drive source. A connecting rod 12 is fixedly connected to the drive end of the motor 11. When the motor 11 is started, the rotation of the drive end of the motor 11 drives the connecting rod 12 to rotate around the center of the motor 11. A gear 16 is rotatably connected to the inner wall of the drum body 3, which fixes the rotation position of the gear 16. Two toothed plates 15 are slidably connected to the inner wall of the drum body 3. The outer parts of the two toothed plates 15 are meshed with the outer parts of the gear 16, and the rotation of the gear 16 drives the two toothed plates 15 to change position.
[0036] A cleaning plate 18 is fixedly connected to the bottom of the toothed plate 15. The positional movement of the toothed plate 15 can cause the cleaning plate 18 to move accordingly. The two cleaning plates 18 are slidably connected to the inner wall of the drum body 3 for cleaning the inner wall of the drum body 3. A feeding window 17 is slidably connected to the inner wall of the drum body 3 for feeding materials. A movable column 14 is rotatably connected to the outside of the toothed plate 15. A sliding rod 13 is movably connected to the outside of the movable column 14. The positional movement of the sliding rod 13 can cause the toothed plate 15 to move accordingly by moving the movable column 14. The other end of the connecting rod 12 is movably connected to the inner wall of the sliding rod 13. The positional movement of the connecting rod 12 can cause the sliding rod 13 to move accordingly.
[0037] Working principle: Pressing the two levers 20 along the inner wall of the sliding window 19 causes the two semicircular blocks 7 to move in a mutually restrictive manner, making their contact surfaces flush. This allows the two positioning boxes 6 to separate, moving the two fixing boxes 5 away from each other, thus separating the mesh panel 4 from the fence 1 and enabling its disassembly. During installation, simply align the contact surfaces of the two fixing boxes 5, remove the external force, and the deformed spring 9 will reset, causing the traction rod 8 to move. This allows the levers 20 to pull the semicircular blocks 7, moving their contact surfaces at a certain angle and intersecting with the contact surfaces of the two positioning boxes 6. This fixes the positions of the two positioning boxes 6, the two fixing boxes 5, and the mesh panel 4. This facilitates easy disassembly of the protective net, allows for regular cleaning of accumulated dust, replacement of damaged nets, maintenance of protective performance, reduction of bacterial growth and corrosion, extension of equipment lifespan, reduction of maintenance costs, and ensures smooth ventilation.
[0038] When the motor 11 is started, the rotation of the drive end of the motor 11 drives the connecting rod 12 to rotate around the center of the motor 11. The position change of the connecting rod 12 can push the sliding rod 13 to move. Since the gear 16 restricts the position of the two toothed plates 15, the gear 16 can only move laterally. Thus, the position change of the sliding rod 13 drives the toothed plate 15 to move through the movable column 14. The position change of the toothed plate 15 can drive the gear 16 to rotate. The position change of the gear 16 can drive the other toothed plate 15 to move laterally. The position change of the two toothed plates 15 drives the cleaning plate 18 to move, thereby cleaning the inner wall of the drum 3. Cleaning the inner wall of the soft drum can remove accumulated dust and impurities, avoid blockage affecting airflow or material flow, reduce friction loss and corrosion risk, ensure stable operation of the equipment and extend its service life.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
