Description

Technical Field

[0001] This invention relates to the field of recycling equipment technology, specifically to an injection mold recycling equipment. Background Technology

[0002] Injection mold recycling equipment is a device for recycling, processing and reusing waste generated during the injection molding process. Its process flow is as follows: waste collection, waste sorting and classification, waste crushing, waste cleaning and decontamination, drying, melt regeneration, granulation, quality inspection and re-injection molding. It reduces resource waste and lowers production costs through technical means, and meets environmental protection requirements. It is an important support for the sustainable development of the injection molding industry.

[0003] In the existing technology, the waste crushing and waste cleaning and decontamination of injection mold recycling devices are usually treated as independent processes, which require two independent power systems and control systems. This not only increases the cost of equipment purchase and maintenance, but also increases energy consumption due to the two independent power systems and control systems, further increasing the cost of waste recycling of injection molds and making it impossible to meet the demand for low-cost waste recycling. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The rotating shaft is driven by a motor, which in turn drives a pair of gears to rotate a crushing rod, which in turn drives a pair of crushing rollers to rotate. The crushing rollers crush brittle waste materials and feed the crushed waste materials and water or cleaning liquid into the cleaning tank from the feed shell. As the rotating shaft rotates, it drives a ring rack, an arc plate, and a rotating disk to rotate through a bevel gear. The rotating disk drives the cleaning tank to rotate, causing the crushed waste materials and water or cleaning liquid in the cleaning tank to shake continuously for cleaning. This application enables the linkage operation of waste crushing and cleaning processes with a single motor, which not only reduces the purchase cost of equipment and the number of power systems, but also reduces the maintenance cost of equipment. At the same time, it meets the needs of low-cost waste recycling and improves the economic efficiency of the entire waste recycling process.

[0014] 2. During the reciprocating motion of the cleaning tank, the cleaning pipe drives the rotating rod and its gear six to reciprocate. Because gear six meshes with rack six and rack six is ​​fixed, the movement of gear six causes the rack six to rotate, which in turn drives the rotating rod to rotate. This causes the rotating rod to drive a set of cleaning plates to rotate. As the cleaning plates rotate due to the reciprocating motion of the cleaning tank, they rotate several times to the left and then several times to the right, repeating this cycle. Combined with the triple dynamic cleaning mechanism, this forms a more refined and comprehensive cleaning mechanism. The cyclic forward and reverse rotation of the cleaning plates sweeps the crushed waste material from all directions without dead angles within the cleaning tank, ensuring that both firmly attached and hidden waste materials are thoroughly removed. Furthermore, the rotation of the cleaning plates and the triple dynamic cleaning mechanism work together to produce a powerful stirring and rinsing effect, further accelerating the multi-dimensional movement of the cleaning liquid and the cleaning effect. This maintains a high level of decontamination capability during the cleaning process, thereby further shortening the cleaning cycle and improving overall production efficiency.

Detailed Implementation

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0018] Please see Figures 1-7 As shown, an injection mold recycling device includes a base 1; a brittle material crushing box 3 is fixedly connected to the top of the outer wall of the base 1 via a fixing plate 2; a motor 4 is fixedly connected to the top of the outer wall of the base 1 via a fixing block; a rotating shaft 5 is provided at the output end of the motor 4 and passes through the brittle material crushing box 3; a crushing rod 6 is rotatably connected to one side of the inner wall of the brittle material crushing box 3, and one end of the outer wall of the crushing rod 6 extends to the outside of the brittle material crushing box 3; crushing rollers 7 are fixedly connected to the outer walls of both the crushing rod 6 and the rotating shaft 5; gears 8 are fixedly connected to the outer walls of both the rotating shaft 5 and the crushing rod 6, and a pair of gears 8 mesh with each other; a rotating disk 9 is provided at one end of the outer wall of the rotating shaft 5 via a linkage mechanism, and the rotating disk 9 rotates via the linkage mechanism; a set of placement plates 11 is provided at the top of the outer wall of the rotating disk 9 via a set of circular plates 10; a cleaning tank 13 is provided at the top of the outer wall of the placement plate 11 via a reciprocating block 12; a feed shell 14 is provided at the top of the outer wall of the cleaning tank 13. The linkage mechanism includes a second bevel gear 15; one end of the outer wall of the second bevel gear 15 is fixedly connected to one end of the outer wall of the rotating shaft 5; the bottom end of the outer wall of the rotating disk 9 is rotatably connected to the top end of the outer wall of the base 1; the top end of the outer wall of the rotating disk 9 is fixedly connected to an annular bevel rack 17 through a set of arc plates 16, and the annular bevel rack 17 meshes with the second bevel gear 15; an electric control valve is provided inside the feed housing 14.

[0019] By placing the brittle waste generated from the injection mold into the brittle material crushing box 3, the motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the crushing rod 6 to rotate through a pair of gears 8, thereby driving a pair of crushing rollers 7 to rotate. The crushing rollers 7 crush the brittle waste, which falls from the bottom of the brittle material crushing box 3 and is collected. The crushed waste and water or cleaning liquid are then placed into the cleaning tank 13 through the feed shell 14. At this time, brittle waste continues to be placed into the brittle material crushing box 3 for crushing. While the rotating shaft 5 is rotating, it drives the ring rack 2, the arc plate 16 and the rotating disk 9 to rotate through the bevel gear 2 15, thereby causing the rotating disk 9 to pass through the circular... The forming plate 10, the placement plate 11, and the reciprocating block 12 drive the cleaning tank 13 to rotate, thereby causing the crushed waste and water or cleaning liquid in the cleaning tank 13 to continuously shake and change position for cleaning. This application enables the linkage operation of waste crushing and cleaning processes through a single motor 4, which not only reduces the purchase cost of equipment, reduces the equipment floor space, and reduces the number of power systems, but also reduces the maintenance cost of equipment. At the same time, the reduction in energy consumption allows for effective control of the cost of waste recycling from injection molds, better meets the demand for low-cost waste recycling, and improves the economic benefits of the entire waste recycling process.

[0020] The center of the rotating disk 9 is hollow; the top of the outer wall of the base 1 is fixedly connected to a gear 3 18 by a round rod, and the gear 3 18 is located at the center of the rotating disk 9; the outer walls of a set of circular plates 10 are all fixedly connected to gears 4 19, and the gears 4 19 mesh with gears 3 18; the bottom of the outer walls of a set of circular plates 10 are rotatably connected to the top of the outer wall of the rotating disk 9.

[0021] When the rotating disk 9 drives the circular plate 10 to rotate, the circular plate 10 drives the gear four 19 to rotate accordingly. Since all four gears 19 mesh with gear three 18, and gear three 18 is fixed to the base 1 by a round rod, the rotation of gear four 19 causes the circular plate 10, the placement plate 11, the reciprocating block 12, and the cleaning tank 13 to rotate. This causes the cleaning tank 13 to rotate with the rotating disk 9 and simultaneously with the rotation of the circular plate 10, forming a dual-rotation cleaning mode. This makes the crushed waste and water or cleaning liquid in the cleaning tank 13 form a more complex mixture. Furthermore, the fully mixed motion trajectory and dual-rotation cleaning mode enhance the cleaning effect, allowing the crushed waste to come into full contact with the cleaning liquid, ensuring that stains are effectively removed. This not only improves cleaning efficiency but also shortens cleaning time, further reducing energy consumption. Additionally, the rotation of the cleaning tank 13 makes the liquid flow inside the tank more uniform, avoiding the problem of incomplete cleaning in certain areas and ensuring cleaning quality. Moreover, while improving the cleaning effect, this application does not add an additional power system, maintaining the advantage of a single motor with 4 drives, further meeting the needs of low-cost waste recycling.

[0022] The bottom of the outer wall of the placement plate 11 is fixed to the top of the outer wall of the circular plate 10; the bottom of the outer wall of the reciprocating block 12 is slidably connected to the top of the outer wall of the placement plate 11; the top of the outer wall of the placement plate 11 is rotatably connected to the reciprocating rod 20 through the block 1, and the reciprocating rod 20 and the reciprocating block 12 are in a reciprocating connection relationship; one end of the outer wall of the reciprocating rod 20 is fixed to the bevel gear 21; the inner sidewalls of a set of arc plates 16 are all fixed to the ring bevel rack 22 through the arc blocks; a set of bevel gears 21 meshes with a set of ring bevel racks 22 respectively.

[0023] When the circular plate 10 drives the placement plate 11 to rotate, the placement plate 11 drives the reciprocating rod 20 and the bevel gear 21 on it to rotate via the block 1. Because the bevel gear 21 meshes with the annular bevel rack 22, and the annular bevel rack 22 is fixed to the arc plate 16 by the arc block, the rotation of the bevel gear 21 drives the reciprocating rod 20 to rotate via the annular bevel rack 22. Since the reciprocating rod 20 and the reciprocating block 12 are reciprocatingly connected, the rotation of the reciprocating rod 20 drives the reciprocating block 12 to reciprocate, which in turn drives the cleaning tank 13 to reciprocate and oscillate. This, combined with the rotation of the rotating disk 9 and the rotation of the circular plate 10, forms a triple dynamic cleaning mechanism. This triple dynamic cleaning mechanism enables the crushed waste and cleaning liquid in the cleaning tank 13 and the cleaning pipe to move in a multi-dimensional motion mode, making the cleaning... The crushed waste inside tank 13 generates more intense relative motion with the cleaning liquid. The crushed waste undergoes a complex trajectory of rotation, swaying, and self-rotation within the tank, further enhancing the penetration and cleaning effect of the cleaning liquid. Furthermore, the swaying motion of the cleaning tank 13 driven by the reciprocating block 12 causes the crushed waste to form a periodic displacement within the tank, solving the problem of cleaning dead zones in traditional fixed cleaning methods. The turbulence effect generated by the superposition of the three movements allows the cleaning liquid to penetrate deep into the tiny gaps of the crushed waste, removing the dirt within these gaps. At the same time, the triple dynamic cleaning mechanism does not require an additional power source and is entirely achieved through a single motor 4-drive system. While improving cleaning quality, it maintains the simplicity and economy of the equipment structure, effectively resolving the contradiction between cleaning effect and energy consumption in traditional injection mold waste recycling equipment.

[0024] The bottom of the outer wall of the cleaning tank 13 is fixedly connected to the top of the outer wall of the reciprocating block 12; a rotating rod 23 is rotatably connected to the top of the outer wall of the cleaning tank 13; the bottom of the outer wall of the rotating rod 23 extends into the cleaning tank 13; a set of cleaning plates 24 is fixedly connected to the outer wall of the rotating rod 23; a gear 6 25 is fixedly connected to the top of the outer wall of the rotating rod 23; a rack 6 26 is fixedly connected to the top of the outer wall of the placement plate 11 through a connecting rod, and the gear 6 25 and the rack 6 26 mesh with each other.

[0025] When the cleaning tank 13 reciprocates, the cleaning pipe drives the rotating rod 23 and its gear 25 to reciprocate. Since gear 25 meshes with rack 26, and rack 26 is fixed, the movement of gear 25 causes the rack 26 to rotate, which in turn drives the rotating rod 23 to rotate. This causes the rotating rod 23 to rotate a set of cleaning plates 24. Because the cleaning plates 24 rotate due to the reciprocating motion of the cleaning tank 13, they rotate several times to the left and then several times to the right, repeating this cycle. Combined with the triple dynamic cleaning mechanism, this results in a more refined and comprehensive cleaning process. The cleaning mechanism, with the cyclical forward and reverse rotation of the cleaning plate 24, sweeps the crushed waste in the cleaning tank 13 in an all-round, thorough manner, ensuring that the waste, whether firmly attached or hidden in tiny crevices, is completely removed. Furthermore, the rotation of the cleaning plate 24, in conjunction with the triple dynamic cleaning mechanism, generates a powerful stirring and rinsing effect, further accelerating the multi-dimensional movement and cleaning effect of the cleaning liquid. This maintains a high level of decontamination capability during the cleaning process, thereby further shortening the cleaning cycle and improving overall production efficiency.

[0026] A lifting plate 32 is slidably connected to the inner wall of the cleaning tank 13; the inner wall of the lifting plate 32 is in contact with the outer wall of the rotating rod 23; a bevel gear 8 33 is fixedly connected to the outer wall of the rotating rod 23; a circular rod 34 is rotatably connected to the bottom of the inner wall of the cleaning tank 13 through a pair of connecting blocks; a bevel gear 9 35 is fixedly connected to one end of the outer wall of each pair of circular rods 34, and the pair of bevel gears 9 35 mesh with the bevel gear 8 33; an elliptical block 36 is fixedly connected to the outer wall of each pair of circular rods 34, and the pair of elliptical blocks 36 match the lifting plate 32.

[0027] When the rotating rod 23 rotates, it drives the bevel gear 8 33 to rotate, which in turn drives a pair of bevel gears 9 35 to rotate. The pair of bevel gears 9 35 then drive a pair of circular rods 34 to rotate, which in turn causes a pair of elliptical blocks 36 to rotate. Due to the special shape of the elliptical blocks 36, they periodically squeeze the lifting plate 32 during rotation, causing the lifting plate 32 to slide up and down on the inner wall of the cleaning tank 13. This continuously agitates the settled crushed waste, preventing it from settling and accumulating at the bottom. The up-and-down movement of the lifting plate 32 also changes the position between the crushed waste and the auxiliary plate 29 and the cleaning plate 24, allowing the crushed waste to come into more comprehensive contact with the cleaning liquid, further enhancing the cleaning effect. The up-and-down movement of the lifting plate 32 also promotes the circulation of the liquid in the cleaning tank 13, allowing the cleaning liquid to be more evenly distributed throughout the cleaning tank 13, avoiding the problem of excessively high or low local liquid concentration, thereby improving the uniformity and consistency of cleaning and increasing cleaning efficiency.

[0028] A set of square through grooves 27 is provided on one side of the outer wall of the cleaning plate 24; an auxiliary rod 28 is rotatably connected to the top of the outer wall of the cleaning plate 24, and the bottom end of the outer wall of the auxiliary rod 28 extends into the square through groove 27; a set of auxiliary plates 29 are fixedly connected to the outer walls of the set of auxiliary rods 28, and the set of auxiliary plates 29 are respectively located in the set of square through grooves 27; a gear 30 is fixedly connected to the outer walls of the auxiliary rods 28; an annular rack 31 is fixedly connected to the top of the inner wall of the cleaning tank 13, and the annular rack 31 and the gear 30 mesh with each other.

[0029] When the cleaning plate 24 rotates, it drives the auxiliary rod 28 and the gear 30 on it to rotate. Since the gear 30 meshes with the ring rack 31 and the ring rack 31 is fixed on the cleaning tank 13, the rotation of the gear 30, through the rotation of the ring rack 31, drives the auxiliary rod 28 and the auxiliary plate 29 to rotate. This causes the auxiliary plate 29 to rotate within the square groove 27 on the cleaning plate 24, thus cooperating with the rotation of the cleaning plate 24 to better agitate the crushed waste and the cleaning liquid. The rotation of the auxiliary plate 29 can create a local vortex effect, which complements the large-scale stirring effect of the cleaning plate 24, making the mixing between the crushed waste and the cleaning liquid more uniform. This ensures that the crushed waste is thoroughly cleaned. Furthermore, the rotation of the auxiliary plate 29 within the square groove 27 increases the local impact force on the crushed waste. For some stubborn stains, this localized strong impact can peel them off, further improving the thoroughness of the cleaning. Example 2:

[0030] Please see Figure 1 and Figure 8 As shown, a tough material shearing box 37 is fixedly connected to one side of the outer wall of the fixed plate 2; a set of fixed blades 38 is fixedly connected to one side of the inner wall of the tough material shearing box 37; a shearing rod 39 is rotatably connected to one side of the inner wall of the tough material shearing box 37, and one end of the outer wall of the shearing rod 39 extends to the outside of the tough material shearing box 37; a set of rotating blades 40 is fixedly connected to the outer wall of the shearing rod 39, and the set of rotating blades 40 is matched with a set of fixed blades 38 respectively; a first gear 41 is fixedly connected to the outer wall of the shearing rod 39; the first gear 41 meshes with a pair of gears 8.

[0031] When the rotating shaft 5 drives a pair of gears 8 to rotate, gear 8 drives the first gear 41 to rotate, the first gear 41 drives the shearing rod 39 to rotate, and the shearing rod 39 drives a set of rotating blades 40 to rotate. This causes the brittle waste generated by the injection mold to enter the brittle material crushing box 3, while the tough waste enters the tough material shearing box 37. The tough waste is caught by the grooves on the rotating blades 40. As the rotating blades 40 rotate, they encounter the fixed blades 38, where they are sheared by the combined action of the rotating blades 40 and the fixed blades 38. Because the radius of the first gear 41 is smaller than that of gear 8, the rotation speed of the crushing roller 7 is relatively fast, while the rotation speed of the shearing blades is relatively slow. This allows the brittle waste to be crushed quickly, while the tough waste is sheared at a slower but more stable speed. This ensures that the treatment of the two different types of waste achieves the best results. At the same time, since the entire system is driven by a single motor 4, it not only simplifies the mechanical structure and reduces maintenance costs, but also enables collaborative operation between different processing units. It eliminates the need for additional power sources or complex control systems, improving the efficiency of waste recycling and reducing energy consumption, making the entire recycling process more economical and environmentally friendly.

[0032] In use, this invention involves placing brittle waste from the injection mold into the brittle material crushing box 3 and tough waste into the tough material shearing box 37. The motor 4 drives the rotating shaft 5 to rotate, which in turn drives the crushing rod 6 via a pair of gears 8, thereby rotating a pair of crushing rollers 7. The crushing rollers 7 crush the brittle waste. Simultaneously, as the rotating shaft 5 drives the gears 8, the gears 8 drive the first gear 41 to rotate, which in turn drives the shearing rod 39 to rotate. The shearing rod 39 then drives a set of rotating blades 40 to rotate, causing the tough waste to be caught in the grooves on the rotating blades 40. As the rotating blades 40 rotate, they continue until they encounter the fixed blade 38, where they are sheared by the combined action of the rotating blades 40 and the fixed blade 38. The crushed waste and sheared waste are then collected from the bottom of the brittle material crushing box 3 or the tough material shearing box 37.

[0033] Because the radius of the first gear 41 is smaller than that of the first gear 8, the rotation speed of the crushing roller 7 is relatively fast, while the rotation speed of the shearing blade is relatively slow. This allows brittle waste to be crushed quickly, while tough waste is sheared at a slower but more stable speed, ensuring that the treatment of the two different types of waste achieves the best results.

[0034] The collected crushed waste, sheared waste, and cleaning liquid are fed into the cleaning tank 13 from the feed shell 14. After feeding, the electric control valve at the feed shell 14 is closed. At this time, brittle or tough waste is fed into the brittle material crushing box 3 or the tough material shearing box 37 for crushing or shearing. At this time, the rotating shaft 5 rotates to crush or shear the waste. At the same time, the ring rack 2, the arc plate 16 and the rotating disk 9 are driven to rotate through the bevel gear 2 15. This causes the rotating disk 9 to drive the cleaning tank 13 to rotate through the circular plate 10, the placement plate 11 and the reciprocating block 12. This causes the crushed waste and water or cleaning liquid in the cleaning tank 13 to shake and change position in the cleaning tank 13 for cleaning.

[0035] When the rotating disk 9 drives the circular plate 10 to rotate, the circular plate 10 drives the gear four 19 to rotate accordingly. Since all four gears 19 mesh with gear three 18, and gear three 18 is fixed to the base 1 by a round rod, the rotation of gear four 19 causes the circular plate 10, the placement plate 11, the reciprocating block 12, and the cleaning tank 13 to rotate. This causes the cleaning tank 13 to rotate with the rotating disk 9 and simultaneously with the rotation of the circular plate 10, forming a dual-rotation cleaning mode. This makes the crushed waste and water or cleaning liquid in the cleaning tank 13 form a more complex mixture. Furthermore, the fully mixed motion trajectory and dual-rotation cleaning mode enhance the cleaning effect, allowing the crushed waste to come into full contact with the cleaning liquid, ensuring that stains are effectively removed. This not only improves cleaning efficiency but also shortens cleaning time, further reducing energy consumption. Additionally, the rotation of the cleaning tank 13 makes the liquid flow inside the tank more uniform, avoiding the problem of incomplete cleaning in certain areas and ensuring cleaning quality. Moreover, while improving the cleaning effect, this application does not add an additional power system, maintaining the advantage of a single motor with 4 drives, further meeting the needs of low-cost waste recycling.

[0036] When the circular plate 10 drives the placement plate 11 to rotate, the placement plate 11 drives the reciprocating rod 20 and the bevel gear 21 on it to rotate via the block 1. Since the bevel gear 21 meshes with the annular bevel rack 22, and the annular bevel rack 22 is fixed to the arc plate 16 via an arc-shaped block, the rotation of the bevel gear 21 causes the annular bevel rack 22 to rotate, thereby driving the reciprocating rod 20 to rotate. Because the reciprocating rod 20 and the reciprocating block 12 are in a reciprocating connection, the rotation of the reciprocating rod 20 drives the reciprocating block 12 to reciprocate, causing the reciprocating block 12 to drive the cleaning tank 13 to reciprocate. The oscillation, combined with the rotation of the rotating disk 9 and the rotation of the circular plate 10, forms a triple dynamic cleaning mechanism. This triple dynamic cleaning mechanism causes the crushed waste and cleaning liquid in the cleaning tank 13 and the cleaning pipe to move in a multi-dimensional mode, resulting in more intense relative motion between the crushed waste and the cleaning liquid in the cleaning tank 13. The crushed waste undergoes a composite trajectory of rotation, oscillation and rotation in the tank, which further enhances the penetration and cleaning effect of the cleaning liquid. In addition, the turbulence effect generated by the superposition of the triple motion allows the cleaning liquid to penetrate deep into the tiny gaps of the crushed waste, so that the dirt in the tiny gaps is peeled off.

[0037] When the cleaning tank 13 reciprocates, the cleaning pipe drives the rotating rod 23 and its gear 25 to reciprocate. Since gear 25 meshes with rack 26 and rack 26 is fixed, the movement of gear 25 causes the rotating rod 23 to rotate, which in turn drives a set of cleaning plates 24 to rotate. As the cleaning plates 24 rotate through the reciprocating motion of the cleaning tank 13, they rotate several times to the left and then several times to the right, repeating this cycle. Combined with the triple dynamic cleaning mechanism, this forms a more refined and comprehensive cleaning mechanism. The cyclic forward and reverse rotation of the cleaning plates 24 sweeps the crushed waste material in the cleaning tank 13 from all directions without dead angles, thoroughly removing both firmly attached and hidden crevices. Furthermore, the rotation of the cleaning plates 24, in conjunction with the triple dynamic cleaning mechanism, produces a powerful stirring and scouring effect, further accelerating the multi-dimensional movement and cleaning effect of the cleaning liquid, shortening the cleaning cycle, and improving overall production efficiency.

[0038] When the cleaning plate 24 rotates, it drives the auxiliary rod 28 and the gear 30 on it to rotate. Since the gear 30 meshes with the ring rack 31 and the ring rack 31 is fixed on the cleaning tank 13, the rotation of the gear 30, through the rotation of the ring rack 31, drives the auxiliary rod 28 and the auxiliary plate 29 to rotate. This causes the auxiliary plate 29 to rotate within the square groove 27 on the cleaning plate 24, thus cooperating with the rotation of the cleaning plate 24 to better agitate the crushed waste and the cleaning liquid. The rotation of the auxiliary plate 29 can create a local vortex effect, which complements the large-scale stirring effect of the cleaning plate 24, making the mixing between the crushed waste and the cleaning liquid more uniform. This ensures that the crushed waste is thoroughly cleaned. Furthermore, the rotation of the auxiliary plate 29 within the square groove 27 increases the local impact force on the crushed waste. For some stubborn stains, this localized strong impact can peel them off, further improving the thoroughness of the cleaning.

[0039] When the rotating rod 23 rotates, it drives the bevel gear 8 33 to rotate, which in turn drives a pair of bevel gears 9 35 to rotate. The pair of bevel gears 9 35 then drive a pair of circular rods 34 to rotate, which in turn causes a pair of elliptical blocks 36 to rotate. Due to the special shape of the elliptical blocks 36, they periodically squeeze the lifting plate 32 during rotation, causing the lifting plate 32 to slide up and down on the inner wall of the cleaning tank 13. This continuously agitates the settled crushed waste, preventing it from settling and accumulating at the bottom. The up-and-down movement of the lifting plate 32 also changes the position between the crushed waste and the auxiliary plate 29 and the cleaning plate 24, allowing the crushed waste to come into more comprehensive contact with the cleaning liquid, further enhancing the cleaning effect. The up-and-down movement of the lifting plate 32 also promotes the circulation of the liquid in the cleaning tank 13, allowing the cleaning liquid to be more evenly distributed throughout the cleaning tank 13, avoiding the problem of excessively high or low local liquid concentration, thereby improving the uniformity and consistency of cleaning and increasing cleaning efficiency.

[0040] This application completes the crushing or shearing and cleaning of brittle and tough waste materials using a single motor 4. Furthermore, through multiple mechanical movements, the crushed brittle waste materials or sheared tough waste materials are cleaned more thoroughly while reducing cleaning time and energy consumption, thereby further meeting the needs of low-cost waste recycling and effectively controlling the cost of waste recycling and reuse.
