Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to a user-friendly waste recycling device for leather processing production. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a material that is no longer easily perishable. Leather is composed of natural protein fibers tightly woven in three-dimensional space, and its surface has a special grain layer with natural grain and luster, and a comfortable feel. During the leather processing, some scraps are generated. Leather processing waste contains a large amount of useful components such as natural protein fibers. Through a series of processing technologies, these wastes can be reprocessed into recycled leather, which can be used to make products with relatively low requirements for leather quality, such as insoles, shoe linings, and bag linings, thereby realizing the secondary use of resources and reducing the demand for new leather raw materials.

[0003] In the prior art, patent publication number CN 217857964 U discloses a waste recycling device for leather processing production, including a frame, a crushing mechanism, a conveying mechanism, a dust cover, and a dust collection assembly. The crushing mechanism is located on the frame; the conveying mechanism is arranged on the frame and located below the crushing mechanism; two sets of dust covers are arranged on both sides of the conveying mechanism along the conveying direction; the dust collection assembly includes a dust suction nozzle and a vacuum cleaner that are interconnected, with the dust suction nozzle facing downwards from the crushing mechanism.

[0004] There are some problems. The above solution only sets up a fixed dust suction nozzle facing down towards the crushing mechanism. Since the dust suction nozzle is fixed in position, the area it can cover is limited. Dust generated in some corners or edges of the crushing mechanism may not be captured by the dust suction nozzle, reducing the dust suction effect. Therefore, we propose an easy-to-use waste recycling device for leather processing production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an easy-to-use waste recycling device for leather processing and production. It can make the suction head accurately target the key area where dust is generated, make up for the shortcomings of the fixed suction nozzle, and greatly improve the suction effect, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a user-friendly waste recycling device for leather processing, including a workbench, a crushing chamber at the right end of the workbench, symmetrically distributed crushing rollers rotatably connected between the left and right inner walls of the crushing chamber, a collection chamber placed below the crushing chamber, and a dust removal mechanism.

[0007] Dust removal mechanism: It includes a dust collection pipe, branch pipes, blind flange plates, airtight valves, and dust collection heads.

The dust collection heads are located on the left and right sides of the lower end of the crushing chamber. A branch pipe is provided at the branch port opened on the upper side of the middle of the dust collection pipe. An airtight valve is connected in series in the middle of the branch pipe. The front flange of the upper end of the branch pipe is connected to a blind flange plate, which allows the dust collection head to accurately target the key areas where dust is generated, making up for the shortcomings of fixed dust collection nozzles and greatly improving the dust collection effect.

[0008] Furthermore, a control switch group is provided on the upper side of the workbench, and the input end of the control switch group is electrically connected to an external power supply for stable control.

[0009] Furthermore, the dust removal mechanism also includes telescopic hoses. Telescopic hoses are provided at both the left and right ends of the front side of the dust suction pipe, and dust suction heads are provided at the opposite inner ends of the two telescopic hoses to facilitate the adjustment of the dust suction heads.

[0010] Furthermore, the dust removal mechanism also includes a rotating shaft, an adjusting cylinder, and a bidirectional lead screw. The rotating shaft is installed in the middle of the front and rear sides of the dust collection head. A sliding groove is provided on the front side wall of the workbench, and symmetrically distributed adjusting cylinders are slidably connected inside the sliding groove. The front ends of the rotating shafts on the front side are all located inside the adjacent adjusting cylinders on the front side. The outer arc surfaces of the adjusting cylinders are threaded with tightening bolts. A mounting plate is provided on the left end of the rear inner wall of the workbench. A bidirectional lead screw is rotatably connected between the right side of the mounting plate and the right inner wall of the workbench. The left and right ends of the bidirectional lead screw are respectively threaded to the adjacent rotating shafts on the front side, which facilitates the adjustment of the position and angle of the dust collection head.

[0011] Furthermore, a motor is installed on the left side of the mounting plate. The output shaft of the motor is fixedly connected to the center of the left end face of the bidirectional lead screw.

[0012] Furthermore, a vacuum cleaner is placed on the rear side of the workbench. The vacuum cleaner is installed in conjunction with a vacuuming pipe. The input end of the vacuum cleaner is electrically connected to the output end of the control switch group for vacuuming.

[0013] Furthermore, each of the left ends of the crushing roller is equipped with a gear, and the two gears mesh together. A motor is installed on the upper side of the workbench, and the output shaft of the motor is fixedly connected to the center of the left side of the front gear. The input end of the motor is electrically connected to the output end of the control switch group to drive the crushing roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-use waste recycling device for leather processing has the following advantages:

[0015] When recycling and crushing waste materials in leather processing, a dust removal mechanism is used to extract the dust generated during crushing. The position and angle of the dust suction head are adjustable. Driven by a motor, a two-way lead screw, along with a rear rotating shaft and adjusting cylinder, allows the dust suction heads to move closer or further apart. Turning the handwheel rotates the front rotating shaft to adjust the angle of the dust suction head. After adjustment, it is fixed with a tightening bolt. A telescopic hose is also provided to adapt to adjustment needs. This allows the dust suction head to be precisely aimed at the key areas where dust is generated, compensating for the shortcomings of a fixed dust suction nozzle and significantly improving the dust collection effect during the recycling of waste materials in leather processing.

[0021] 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.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a user-friendly waste recycling device for leather processing, comprising a workbench 1, a control switch group 6 on the upper side of the workbench 1, the input end of the control switch group 6 being electrically connected to an external power source, a crushing chamber 3 on the right end of the workbench 1, symmetrically distributed crushing rollers 4 rotatably connected between the left and right inner walls of the crushing chamber 3, each crushing roller 4 having a gear 5 on its left end, the two gears 5 meshing together, a motor 8 mounted on the upper side of the workbench 1, the output shaft of the motor 8 being fixedly connected to the center of the left side of the front gear 5, and the input end of the motor 8 being electrically connected to the control switch. At the output end of group 6, a collection bin 9 is placed on the lower side of the crushing bin 3. The worker operates the control switch group 6 to make the motor 8 run. The output shaft of the motor 8 drives the front gear 5 to rotate. Under the meshing action, the rear gear 5 rotates synchronously (the two gears 5 rotate in opposite directions). At this time, the two gears 5 drive the crushing roller 4 to rotate. Then the worker puts the leather scraps generated during the leather processing into the interior of the crushing bin 3. The leather scraps then fall into the interior of the collection bin 9 through the crushing roller 4. The worker can then take them out, which is convenient for recycling the waste generated during leather processing. It also includes a dust removal mechanism 2.

[0023] Dust removal mechanism 2 includes a dust collection pipe 21, a branch pipe 22, a blind flange plate 23, an airtight valve 24, and a dust collection head 27. The dust collection pipe 21 is located in the middle of the workbench 1, with both the left and right ends of the front side of the dust collection pipe 21 inside the workbench 1. Adjustable dust collection heads 27 are provided at both the left and right ends of the front side of the dust collection pipe 21, and the dust collection heads 27 are located on the left and right sides of the lower end of the crushing chamber 3. The dust removal mechanism 2 also includes a telescopic hose 29, with telescopic hoses 29 provided at both the left and right ends of the front side of the dust collection pipe 21. Dust collection heads 27 are provided at the opposite inner ends of the two telescopic hoses 29. A branch pipe 22 is provided at the branch opening on the upper side of the middle of the dust collection pipe 21. An airtight valve 24 is connected in series in the middle of the branch pipe 22, and a blind flange plate is connected to the front flange of the upper end of the branch pipe 22. 23. The dust removal mechanism 2 also includes a rotating shaft 25, an adjusting cylinder 26, and a two-way lead screw 28. The rotating shaft 25 is fitted onto the center of both the front and rear sides of the dust collection head 27 (the two rear rotating shafts 25 are rotatably connected to the center of the rear side of the dust collection head 27, and the two front rotating shafts 25 are fixedly connected to the center of the front side of the dust collection head 27). A sliding groove 7 is provided on the front side wall of the workbench 1. Symmetrically distributed adjusting cylinders 26 are slidably connected inside the sliding groove 7. The front ends of the front rotating shafts 25 are located inside the adjacent front adjusting cylinders 26 (a handwheel is provided at the front end of each of the two front rotating shafts 25). Tightening bolts 13 are threaded onto the outer arc surface of each adjusting cylinder 26. A mounting plate 10 is provided on the left end of the rear inner wall of the workbench 1. The right side of the mounting plate 10 is flush with the workbench. A bidirectional lead screw 28 is rotatably connected between the right inner wall of the workbench 1 and the left and right ends of the bidirectional lead screw 28 are threadedly connected to the adjacent rotating shaft 25 on the front side. A motor 11 is installed on the left side of the mounting plate 10. The output shaft of the motor 11 is fixedly connected to the center of the left end face of the bidirectional lead screw 28. The input end of the motor 11 is electrically connected to the output end of the control switch group 6. A vacuum cleaner 12 is placed on the rear side of the workbench 1. The vacuum cleaner 12 is installed in conjunction with the vacuum pipe 21 (the vacuum cleaner 12 has a vacuum pipe at the vacuum port, and the vacuum pipe is connected to the vacuum pipe 21). The input end of the vacuum cleaner 12 is electrically connected to the output end of the control switch group 6. The dust removal mechanism 2 sucks up the dust generated during the crushing of leather scraps. First, the worker adjusts the position of the two vacuum heads 27 according to the situation. The angle is controlled by the control switch group 6, which drives the motor 11 to operate. The output of the motor 11 drives the double-sided lead screw 28 to rotate. Under the threaded engagement of the double-sided lead screw 28, the two rotating shafts 25 on the rear side drive the two suction heads 27 to move away from or towards each other. During this process, the movement of the suction heads 27 is achieved by the two rotating shafts 25 on the front side, which drag the adjacent adjusting cylinder 26 to slide inside the slide groove 7. Then, the worker rotates the handwheel to make the two rotating shafts 25 drive the two suction heads 27 to rotate. Then, the two tightening bolts 13 are tightened, which tighten the adjacent rotating shafts 25 to maintain the adjusted angle of the suction heads 27 (the telescopic hose 29 extends and retracts accordingly during the adjustment of the suction heads 27). The worker can also choose whether to let the branch pipe 22 participate in the vacuuming work. If it is necessary,The worker removes the blind flange plate 23, then installs a suction head on the front end of the branch pipe 22, opens the airtight valve 24, and finally starts the vacuum cleaner 12 by controlling the switch group 6. The vacuum cleaner 12 begins suction work through the suction pipe 21, branch pipe 22, and corresponding suction heads 27, ensuring that each suction nozzle is aimed at the key areas where dust is generated.

[0024] The working principle of the easy-to-use waste recycling device for leather processing provided by this utility model is as follows: First, the worker operates the control switch group 6 to make the motor 8 run. The output shaft of the motor 8 drives the front gear 5 to rotate. Under the meshing action, the rear gear 5 rotates synchronously (the two gears 5 rotate in opposite directions). At this time, the two gears 5 drive the crushing roller 4 to rotate. Then, the worker puts the leather scraps generated during the leather processing into the crushing chamber 3. The leather scraps are then crushed by the crushing roller 4 and fall into the collection chamber 9, where the worker can take them out. During this process, the dust removal mechanism 2 sucks up the dust generated during the crushing of the leather scraps. First, the worker adjusts the position and angle of the two dust suction heads 27 according to the situation, and operates the control switch group 6 to make the motor 11 run. The output of the motor 11 drives the bidirectional lead screw 28 to rotate. Under the threaded engagement of the bidirectional lead screw 28, the two rear rotating... Shaft 25 drives two suction heads 27 to move away from or closer to each other. During this process, the movement of suction heads 27 is achieved by the two rotating shafts 25 on the front side, which drag the adjacent adjusting cylinders 26 to slide inside the slide groove 7. Then, the worker rotates the handwheel to make the two rotating shafts 25 rotate the two suction heads 27. Then, the worker tightens the two tightening bolts 13, which tighten the adjacent rotating shafts 25 to maintain the angle of the suction heads 27 after adjustment (the telescopic hose 29 extends and retracts accordingly during the adjustment of the suction heads 27). The worker can also choose whether to let the branch pipe 22 participate in the vacuuming work. If it is necessary, the worker removes the blind hole flange plate 23, then installs a suction head on the front end of the branch pipe 22, then opens the airtight valve 24, and finally, the worker turns on the vacuum cleaner 12 by controlling the switch group 6. The vacuum cleaner 12 starts vacuuming through the vacuum pipe 21, the branch pipe 22 and the corresponding suction head 27.

[0025] It is worth noting that the vacuum cleaner 12 disclosed in the above embodiments can be model MCJC-700-S, and the motor 8 and motor 11 can both be model Y90L-4. The control switch group 6 is provided with control buttons that correspond one-to-one with the vacuum cleaner 12, motor 8 and motor 11 and are used to control their switching.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
