Description

Technical Field

[0001] The invention relates to the technical field of recycling and treatment, in particular to a recycling and treatment device for processing polyurethane waste. Background Art

[0002] In the current polyurethane waste recycling and processing industry, the existing recycling and processing equipment has a series of problems that need to be solved urgently.

[0003] Complex power system: Traditional polyurethane waste recycling and processing equipment usually uses multiple motors or complex power transmission systems to drive different components, which not only increases the cost of the equipment, but also leads to high energy consumption and high maintenance difficulty. For example, in some large recycling equipment, different motors are used to drive the crushing components and the conveying components, which not only makes the wiring complicated, but also makes it difficult to coordinate between the power sources, which is prone to failure.

[0004] Disordered feeding: Many existing devices lack effective control mechanisms in the feeding process, and polyurethane waste is prone to accumulation and blockage when entering the crushing area. This not only affects the normal operation of the equipment, but also reduces production efficiency and increases manual cleaning costs. For example, in some simple crushers, waste is directly poured into the crushing chamber, which often causes material blockage and requires shutdown for cleaning.

[0005] Poor crushing quality: The existing crushing methods are often relatively simple, making it difficult to crush polyurethane waste comprehensively and meticulously. The particle size of the crushed waste is uneven, which affects the subsequent recycling effect. For example, some crushers only rely on simple extrusion or impact to crush, resulting in a large number of large pieces of material in the waste, which requires secondary crushing, increasing processing costs and time.

[0006] To address these issues, this application uses a unique structural design to achieve the coordinated operation of multiple components using a single motor, optimize the feeding method, and improve the crushing effect, aiming to provide a more efficient and reliable solution for the recycling and processing of polyurethane waste. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides a recycling and processing device for processing polyurethane waste, which solves the problems raised in the above background technology.

[0008] Technical solution: To solve the above technical problems, according to one aspect of the present invention, more specifically, it is a recycling and treatment device for processing polyurethane waste, including a hopper. A fixed seat is fixed below the interior of the hopper. A motor is fixed to the bottom of the fixed seat. The top of the output shaft of the motor penetrates through the upper surface of the fixed seat and is fixed with a screw barrel. A screw rod is threadedly connected inside the screw barrel. A lifting top is fixed to the top of the screw rod. Transfer blocks are fixed to the left and right sides of the top of the lifting top. One end of the transfer block away from the screw rod is rotatably connected to a rotating plate. A fixed jaw plate is rotatably connected to the bottom of the rotating plate. A sliding frame is rotatably connected to the bottom of the fixed jaw plate. The bottom of the sliding frame is slidably connected to the upper surface of the fixed seat. A connecting rod is rotatably connected inside the sliding frame. A lifting frame is threadedly connected to the upper part of the outer surface of the screw barrel. The left and right ends of the lifting frame are respectively rotatably connected to the tops of the two connecting rods. Slope plates are fixed to the left and right sides inside the hopper. A jaw frame is arranged below the slope plates. An inner groove is formed inside the jaw frame. An axial groove is formed above the inner groove. The front and rear ends of the axial groove penetrate through the front and rear surfaces of the jaw frame respectively. Two axial rods are rotatably connected inside the axial groove. A first transmission roller is jointly fixed between the two axial rods. A second transmission roller is rotatably connected to the lower part inside the inner groove. A first gear is fixed to the outer surface of the second transmission roller. A first transmission belt is jointly arranged on the outer surfaces of the second transmission roller and the first transmission roller.

[0009] Furthermore, a bottom groove is formed at the bottom of the jaw frame. A sliding groove is formed on one side of the jaw frame close to the fixed jaw plate. The sliding groove is communicated with the bottom groove. The outside of the first gear penetrates into the sliding groove. A movable jaw plate is slidably connected inside the sliding groove. Through-type movable grooves are formed on the front and rear surfaces of the bottom groove. A movable rod is jointly movably connected inside the two movable grooves. A piston rod is fixed to the outer surface of the movable rod. One end of the piston rod away from the jaw frame penetrates to the outside of the hopper and is fixed with a connecting plate. Second gears are respectively arranged through the front and rear surfaces of the hopper. The second gears are rotatably connected to the hopper. A transmission wheel is fixed to the top of the second gear. A second transmission belt is jointly arranged on the outer surfaces of the two transmission wheels and the outer surface of the screw barrel.

[0010] Furthermore, a number of tooth grooves are formed on one side of the movable jaw plate close to the first gear. The movable jaw plate is meshed with the first gear through the tooth grooves; the second gear is meshed with the adjacent connecting plate.

[0011] Furthermore, a sliding plate is fixed to the outer surface of the movable jaw plate inside the bottom groove. A guide rod is connected through the sliding plate. The guide rod is fixed to the upper surface inside the bottom groove.

[0012] Furthermore, the connecting plate is of an L-shaped structure. The two connecting plates are respectively located at the left front and right rear of the hopper.

[0013] Furthermore, the opposite sides of the movable jaw plate and the fixed jaw plate are provided with broken lines.

[0015] Furthermore, the two opposite ends of the shaft rods are fixedly connected to the inner surface of the hopper.

[0016] The beneficial effects of the recycling and processing device for polyurethane waste processing of the present invention are:

[0017] (1) Single motor drive, efficient structure coordination: Only a single motor drive can make multiple key components such as the fixed jaw plate, jaw frame, and movable jaw plate operate in an orderly manner, reducing the complexity and cost of the power source and improving the overall energy efficiency of the equipment. The linkage and coordination between the various components are close, achieving efficient crushing operations.

[0018] (2) Orderly feeding of waste materials: The peristaltic fixed jaw plate, rotating plate and lifting top cooperate with each other, which can make the polyurethane waste enter between the fixed jaw plate and the movable jaw plate in an orderly manner, avoiding problems such as waste accumulation and blockage, and ensuring the smooth progress of the crushing process.

[0019] (3) Adapt to waste materials of different shapes: The fixed jaw plate and jaw frame that are constantly approaching and moving away can automatically adjust their relative positions according to the different shapes of the waste materials, thereby enhancing the adaptability of the equipment to polyurethane waste materials of various shapes and expanding the scope of application of the equipment.

[0020] (4) Efficient and meticulous crushing: The vibration of the movable jaw plate cooperates with the coordinated movement of the fixed jaw plate and the jaw frame to crush the waste at multiple angles and in all directions, which can achieve more efficient and meticulous crushing operations, improve the crushing quality, and facilitate subsequent recycling and processing.

Detailed implementation manners

[0031] In the following, the present invention will be described in detail with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0033] Refer to Figure 1-8, a recycling and treatment device for processing polyurethane waste, including a hopper 1. A fixed seat 2 is fixed below the interior of the hopper 1. A motor 3 is fixed to the bottom of the fixed seat 2. The top of the output shaft of the motor 3 penetrates through the upper surface of the fixed seat 2 and is fixed with a screw barrel 4. A screw rod 5 is threadedly connected inside the screw barrel 4. The top of the screw rod 5 is fixed with a lifting top 6. Transfer blocks 7 are fixed on the left and right sides of the top of the lifting top 6. One end of the transfer block 7 away from the screw rod 5 is rotatably connected with a rotating plate 8. The bottom of the rotating plate 8 is rotatably connected with a fixed jaw plate 9. The bottom of the fixed jaw plate 9 is rotatably connected with a sliding frame 10. The bottom of the sliding frame 10 is slidably connected with the upper surface of the fixed seat 2. A connecting rod 12 is rotatably connected inside the sliding frame 10. A lifting frame 11 is threadedly connected above the outer surface of the screw barrel 4. The left and right ends of the lifting frame 11 are respectively rotatably connected with the tops of the two connecting rods 12. Slope plates 33 are fixed on the left and right sides inside the hopper 1. Below the slope plates 33 is provided a jaw frame 13. An inner groove 14 is opened inside the jaw frame 13. A shaft groove 18 is opened above the interior of the inner groove 14. The front and rear ends of the shaft groove 18 penetrate through the front and rear surfaces of the jaw frame 13 respectively. Two shaft rods 15 are rotatably connected inside the shaft groove 18. A first transmission roller 16 is jointly fixed between the two shaft rods 15. A second transmission roller 17 is rotatably connected below the interior of the inner groove 14. A first gear 19 is fixed on the outer surface of the second transmission roller 17. A first transmission belt 20 is jointly provided on the outer surfaces of the second transmission roller 17 and the first transmission roller 16;

[0034] A bottom groove 21 is opened at the bottom of the jaw frame 13. A sliding groove 22 is opened on one side of the jaw frame 13 close to the fixed jaw plate 9. The sliding groove 22 communicates with the bottom groove 21. The outside of the first gear 19 penetrates into the interior of the sliding groove 22. A moving jaw plate 23 is slidably connected inside the sliding groove 22. Through-type moving grooves 26 are opened on the front and rear surfaces of the interior of the bottom groove 21. A moving rod 27 is jointly movably connected inside the two moving grooves 26. A piston rod 28 is fixed on the outer surface of the moving rod 27. One end of the piston rod 28 away from the jaw frame 13 penetrates to the outside of the hopper 1 and is fixed with a connecting plate 29. Gear two 30 is penetrated and arranged on the front and rear surfaces of the hopper 1. The gear two 30 is rotatably connected with the hopper 1. A transmission wheel 31 is fixed on the top of the gear two 30. A second transmission belt 32 is jointly provided on the outer surfaces of the two transmission wheels 31 and the outer surface of the screw barrel 4;

[0035] When in use, polyurethane waste is put in through the top of the hopper 1, and the motor 3 servo runs forward and reverse, so that the screw barrel 4 rotates, thereby causing the lifting frame 11 to reciprocate and move up and down. Under the linkage of the connecting rod 12, the two slides 10 move back or forward or relative to each other. At the same time, the screw 5 drives the lifting top 6 and the adapter block 7 to move up and down. During the movement of the rotating plate 8 and the slide 10, the fixed jaw plate 9 performs undulating creeping. At the same time, under the transmission of the transmission belt 2 32 and the transmission wheel 31, the gear 2 30 reciprocates, and the piston rod 28 is pushed and pulled left and right through the meshing connecting plate 29. The movable rod 27 moves inside the movable groove 26, so that the jaw frame 13 and its internal structure swing around the two shafts 15. During the swing, the transmission belt 120 is operated by the friction of the relative movement of the fixed transmission roller 16 and the movable transmission roller 2 17, so that the transmission roller 2 17 and the gear 19 rotate axially. The reciprocating gear 19 makes the movable jaw plate 23 shake continuously along the inside of the slide groove 22 under the meshing, so that the waste can be better crushed and ground in cooperation with the creeping fixed jaw plate 9 and the swinging jaw frame 13;

[0036] Based on a single motor 3, the fixed jaw plate 9, jaw frame 13 and movable jaw plate 23 in the device operate in an orderly manner. The creeping fixed jaw plate 9, rotating plate 8 and lifting top 6 can make the waste enter between the fixed jaw plate 9 and the movable jaw plate 23 in an orderly manner for crushing. The fixed jaw plate 9 and jaw frame 13 that are constantly approaching and moving away can make waste of different shapes available, and achieve more efficient and detailed crushing operations under the shaking of the movable jaw plate 23.

[0037] Reference Figure 3-7 A plurality of tooth grooves are provided on one side of the movable jaw plate 23 close to the gear 19, and the movable jaw plate 23 is meshed and connected with the gear 19 through the tooth grooves; the connecting plate 29 is an L-shaped structure, and the two connecting plates 29 are respectively located at the left front and right rear of the hopper 1, and the gear 2 30 is meshed and connected with the adjacent connecting plates 29. The L-shaped structure enables the connecting plate 29 to be connected with the front and rear gears 2 30 while connecting the piston rods 28 on the left and right sides.

[0038] Reference Figure 4-8 The outer surface of the movable jaw plate 23 is located inside the bottom groove 21 and a slide plate 24 is fixed thereon. A guide rod 25 is connected to the inside of the slide plate 24 and is fixed to the upper surface of the bottom groove 21. Under the limitation of the slide plates 24 and 24, the movable jaw plate 23 can be stably shaken for crushing.

[0039] Reference Figure 4-5 , the movable jaw plate 23 and the fixed jaw plate 9 are provided with crushing lines on the opposite sides; the crushing lines of the two jaw plates are different.

[0040] Reference Figure 2-3, the front and back surfaces of the jaw frame 13, the lifting jack 6, the fixed jaw plate 9, and the rotating plate 8 are all in close contact with the inner surface of the hopper 1 to prevent waste from falling through the gaps between the hopper 1 and the jaw frame 13, the lifting jack 6, the fixed jaw plate 9, and the rotating plate 8. Under the limitation of the hopper 1, when the screw barrel 4 rotates, the lifting jack 6 will not cause the screw rod 5 and the lifting jack 6 to rotate accordingly, so as to achieve stable lifting.

[0041] Refer to Figure 2 , Figure 6 , Figure 7 , both opposite ends of the two shaft rods 15 are fixedly connected to the inner surface of the hopper 1.

[0042] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
