Description

Technical Field

[0001] This invention belongs to the field of waste recycling technology, and specifically relates to a recycling device for injection molding waste. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. However, the use of injection molding machines generates a large amount of plastic waste during operation. To conserve resources, this waste needs to be recycled and reprocessed for reuse.

[0003] However, existing recycling devices typically produce crushed debris during waste processing, causing environmental pollution. Furthermore, they process large pieces directly, which may overload the cutting and crushing equipment and pose a risk to its long-term use. Additionally, waste may accumulate and clog during feeding, affecting efficiency. Therefore, a recycling device for injection molding waste is proposed. Summary of the Invention

[0004] This invention provides a recycling device for injection molding waste, which aims to solve the problems of environmental pollution caused by the pulverized debris during waste processing, the direct processing of large pieces which may overload the cutting and crushing equipment and pose a danger to its long-term use, and the potential accumulation and blockage of waste during feeding, affecting efficiency.

[0005] This invention provides a recycling device for injection molding waste, including a recycling and processing shell.

[0006] A feeding shell, which is installed in the middle of the top of the recycling shell, is used to feed injection molding waste.

[0007] An annular shell, which is installed on the inner top wall of the recycling processing shell, is used to process the falling waste material.

[0008] An anti-accumulation component is installed in the feeding shell to vibrate and prevent blockage, and to perform initial crushing of injection molding waste to prevent load on subsequent processes.

[0009] A transmission assembly, which is installed on both sides of the recycling shell, is used to enable the anti-stacking assembly to operate.

[0010] A pressure assembly is installed at the top center of the feeding shell to compress the injection molding waste and prevent blockage.

[0011] A protective shell is installed on the inner bottom wall of the recycling shell. A second motor is installed in the protective shell. A cutting rod is fixedly connected to the output end of the second motor. The cutting rod protrudes from the protective shell and is fixedly connected to several pairs of vertically distributed cutting blades. Two openings are opened on both the front and rear side walls of the recycling shell. A discharge shell matching the position of the openings is connected to the outer wall of the recycling shell.

[0012] A reprocessing assembly, installed in the middle of the annular shell, is used to further process and refine the falling waste material.

[0013] An exhaust assembly, distributed within the protective shell and the annular shell, is used to generate traction airflow to reduce the dispersion of debris.

[0014] By adopting the above technical solution, injection molding waste is fed from the top of the feeding shell, and then undergoes preliminary treatment through the anti-accumulation component and the pressing component, breaking it into small pieces to prevent blockage and high load in subsequent processing. Then it falls into the reprocessing component for further crushing into particles. The processing exhaust component guides the airflow to introduce the generated debris, reducing the dispersion pollution. Subsequently, it is filtered through the filter section of the reprocessing component. The waste that meets the requirements is filtered and discharged from the bottom outlet of the recycling shell, while the waste that does not meet the requirements moves through the filter section to the opening and is discharged through the discharge shell.

[0015] Furthermore, the anti-accumulation component includes two symmetrically distributed telescopic swing plates. Each telescopic swing plate includes a sleeve plate and a movable plate. The top of the sleeve plate is rotatably connected to the side wall of the feeding shell. The bottom of the movable plate is rotatably connected to a second swing plate. The movable plate extends into the sleeve plate and is slidably connected. The bottom of the second swing plate is rotatably connected to an installation plate. The bottom of the installation plate is fixedly connected to the top of the recycling shell. A crushing roller is installed on the installation plate.

[0016] By adopting the above technical solution, since both the telescopic swing plate one and the swing plate two are movably connected and can swing in conjunction with the transmission component, the telescopic swing plate one can swing and extend accordingly, causing the material feeding injection activity, preventing accumulation and blockage. In addition, a motor can be connected to the crushing roller to drive the crushing roller to rotate and initially crush the waste into small pieces, preventing the subsequent processing from being overloaded.

[0017] Furthermore, the transmission assembly includes mounting blocks installed on both sides of the top of the recycling shell. A dual-axis motor is mounted on the front side of the mounting block on the left side, and a transmission rod is rotatably connected to the mounting block on the right side. Half gears are fixedly connected to the front output end of the dual-axis motor and the front end of the transmission rod. A movable frame is sleeved on the outer side of the half gear. Several teeth are installed on both sides of the inner wall of the movable frame. A movable rod is fixedly connected to the side of the movable frame closest to it. The other end of the movable rod extends into the feeding shell and is rotatably connected to the connection between the telescopic swing plate and the swing plate. The transmission rod is fixedly connected to the rear output end of the dual-axis motor. Two sprockets are mounted on the transmission rod. A sprocket is fixedly connected to the rear end of the transmission rod.

[0018] By adopting the above technical solution, the rotation of the front and rear output ends of the dual-axis motor causes the transmission rod 1 and the left half gear to rotate. The transmission rod 1 drives the sprocket 1, which in turn causes the right transmission rod 2, sprocket 2, sprocket 3, and rotating rod to rotate. The transmission rod 2 drives the right half gear to rotate. The half gear, through its engagement with the teeth on the moving frame, can drive the moving frame to move back and forth. This, in turn, causes the moving rod to drive the telescopic swing plate 1 and swing plate 2 to swing back and forth, forming a movement that prevents the accumulation and blockage of injection molding waste.

[0019] Furthermore, the tooth body meshes with the half gear, and one of the sprockets is connected to the other sprocket via a chain drive.

[0020] By adopting the above technical solution, the moving frame can be driven to move through the meshing of the half gear and the tooth body, and the chain can drive the first sprocket to rotate the second sprocket.

[0021] Furthermore, the pressing assembly includes a mounting shell fixedly connected to the middle of the top of the feeding shell, a rotating rod rotatably connected in the mounting shell, a cam fixedly connected to the outer side of the rotating rod, a movable plate slidably connected in the mounting shell, a pressing rod fixedly connected to the bottom of the movable plate, a pressing block fixedly connected to the bottom of the pressing rod, a sprocket three fixedly connected to the rear end of the rotating rod protruding from the mounting shell, and springs installed on both sides of the bottom of the movable plate.

[0022] By adopting the above technical solution, the sprocket and the rotating rod rotate through the transmission of the motor. The rotation of the rotating rod drives the cam to rotate, which allows the moving plate to move vertically in conjunction with the spring's reset and the intermittent pressure when the cam rotates. This intermittently presses the injection molding waste, further assisting in the discharge of waste and improving efficiency. No manual handling by staff is required.

[0023] Furthermore, another sprocket is connected to sprocket three via a chain drive.

[0024] By adopting the above technical solution, the rotating rod is rotated through chain drive, reducing the need for a power source.

[0025] Furthermore, the reprocessing assembly includes a sliding sleeve slidably connected to a cutting rod. The top of the cutting rod has a wave groove that surrounds the outer wall. Four connecting rods are evenly fixedly connected to the outer side of the sliding sleeve. Three pressing blocks are slidably connected to the cutting rod. Each pressing block has a filter plate fixedly connected to the bottom of an annular shell. A vertical rod is fixedly connected to the bottom of the end of each connecting rod away from the sliding sleeve. Two pulling rods are rotatably connected to the bottom of the vertical rods on the left and right sides. The filter plate has several evenly distributed holes. A filter frame is rotatably connected to the bottom of the pulling rod on one side. The sides of the two filter frames that are far apart are rotatably connected to the inner wall of the recycling shell. A rubber tension band is installed between the ends of the filter frames that are close to each other. A filter screen is installed in the filter frame.

[0026] By adopting the above technical solution, the rotation of the cutting rod driven by motor two allows the cutting blade to further crush the waste. Simultaneously, during crushing, the rotation of the corrugated groove drives the vertical reciprocating movement of the sliding sleeve, which in turn causes the connecting rod and vertical rod to move vertically. This vertical movement of the vertical rod drives the matching pressing block to move vertically, intermittently pressing the waste falling onto the filter plate. Waste that meets the requirements will fall directly from the outlet, while waste that does not meet the requirements will be better crushed by the cutting blade during the pressure on the filter plate. Furthermore, the system avoids continuously forcibly cutting uncrushed waste, instead allowing it to fall from the gap between the two filter plates for further cutting, reducing the cutting load. The multi-layer design ensures thorough cutting, guaranteeing both the safety and quality of the device. After processing, waste that falls onto the filter screen and does not meet the requirements will be filtered out. Simultaneously, the vertical movement of the vertical rod causes the filter frame to swing vertically via the pulling rod, moving the waste. Qualified waste will fall from the filter screen, while unqualified waste will be discharged from the opening and then from the discharge shell, thus classifying the waste for subsequent processing.

[0027] Furthermore, the vertical rod passes through the filter plate, and sliders matching the wave groove are installed on both inner walls of the connecting rod. The end of the connecting rod away from the sliding sleeve is fixedly connected to slider two, which is slidably connected to the inner wall of the annular shell.

[0028] By adopting the above technical solution, the sliding sleeve can be moved vertically by the first slider as the wave groove rotates, and the connecting rod is limited by the second slider to ensure that the sliding sleeve will not rotate when it moves vertically.

[0029] Furthermore, the pressing block includes a block body, a drop opening, and a connecting groove. The two sides of the block body have symmetrically distributed drop openings. The middle of the block body is slidably connected to the cutting rod. The other two sides of the block body have connecting grooves. The top of the block body is inclined towards the drop opening. The drop openings on the two blocks distributed vertically are cross-shaped. When the drop openings are distributed horizontally, the front and rear sides of the drop openings are fixedly connected to the vertical rod through the connecting grooves.

[0030] By adopting the above technical solution, the connecting groove and the corresponding vertical rod are fixedly connected, the corresponding vertical rod is slidably connected, and the pressing round blocks set up above and below can be arranged in a cross shape. When the drop opening is distributed to the left and right, the connecting groove is connected to the vertical rods distributed in front and behind, and the filter plates below are distributed to the left and right. When the drop opening is distributed in front and behind, the filter plates below are distributed in front and behind, which allows the waste to fall onto the corresponding filter plates for processing and will not fall from the gaps between the filter plates.

[0031] Furthermore, the exhaust assembly includes an exhaust fan mounted on the cutting rod, exhaust pipes are installed on the top of both sides of the protective shell, an exhaust channel is opened in the wall of the annular shell, one bottom end of the exhaust pipe is connected to the inside of the protective shell, one top end of the exhaust pipe is connected to the exhaust channel, several exhaust ports are opened on the top of the inner wall and the outer wall of the annular shell, which are connected to the exhaust channel, a flexible hose connected to the feeding shell is connected to the top of the exhaust channel, the flexible hose passes through the swing plate and is connected to the inside of the feeding shell, a partition is provided on the top of the motor, and an exhaust port connected to the outside is opened on the rear wall of the recycling shell.

[0032] By adopting the above technical solution, the rotation of the cutting rod drives the exhaust fan to rotate, thereby generating suction. Air is drawn in through the exhaust port and hose to attract the debris generated during crushing. The debris is then sent to the exhaust port through the exhaust channel and exhaust pipe and processed by an external gas treatment device to reduce pollution.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. This invention, through the anti-accumulation component and the transmission component, effectively prevents the accumulation and blockage of injection molding waste during feeding by reciprocating oscillation; the pressing component further assists the waste feeding through intermittent pressure, ensuring a smooth feeding process, reducing manual intervention, and improving processing efficiency. The crushing roller in the anti-accumulation component performs initial crushing of the fed waste, breaking down large pieces of waste into smaller pieces, avoiding excessive equipment load during subsequent fine processing, and extending the service life of the equipment.

[0035] 2. This invention further crushes waste materials through a reprocessing component using a cutting blade, combined with multi-layer filter plates and filter frames: waste materials that meet the particle size requirements fall directly from the outlet or filter screen and are discharged; waste materials that do not meet the requirements are carried to the next layer for further processing by the cutting blade, or are oscillated and screened by the filter frame and discharged from the discharge shell, achieving fine classification and improving recycling quality. In addition, the cross-shaped design of the multi-layer filter plates and the pressing round blocks avoids hard cutting load, protects the equipment while ensuring crushing effect, and improves overall reliability.

[0036] 3. The present invention uses an exhaust assembly to draw in and centrally discharge the debris generated during the crushing process through airflow, effectively reducing debris dispersion and improving the working environment.

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] Reference Figures 1-9 This invention provides a recycling device for injection molding waste, including a recycling and processing shell 1.

[0051] Feeding shell 2 is installed at the top center of recycling shell 1 and is used to feed injection molding waste.

[0052] Annular shell 3 is installed on the inner top wall of recycling shell 1 to dispose of falling waste materials.

[0053] Anti-accumulation component, installed in feeding shell 2, is used to vibrate and prevent blockage and to initially crush the injection molding waste to prevent load on subsequent processes;

[0054] The transmission assembly is installed on both sides of the recycling shell 1 to enable the anti-stacking assembly 1 to operate.

[0055] The pressure assembly is installed at the top center of the feeding shell 2 to compress the injection molding waste and prevent blockage.

[0056] The protective shell 7 is rectangular in plan view. The protective shell 7 is installed on the inner bottom wall of the recycling shell 1. The protective shell 7 is equipped with a motor 8. The output end of the motor 8 is fixedly connected to a cutting rod 9. The cutting rod 9 protrudes from the protective shell 7 and is fixedly connected to several pairs of vertically distributed cutting blades 12. Two openings 13 are opened on both the front and rear side walls of the recycling shell 1. A discharge shell 14 matching the position of the openings 13 is connected to the outer wall of the recycling shell 1. A material discharge port is opened at the bottom of the recycling shell 1.

[0057] The reprocessing component is installed in the middle of the annular shell 3 and is used to further process and refine the falling waste.

[0058] The exhaust assembly, distributed within the protective shell 7 and the annular shell 3, is used to generate traction airflow to reduce the dispersion of debris.

[0059] Thus, the injection molding waste is fed from the top of the feeding shell 2, and then undergoes preliminary treatment through the anti-accumulation component and the pressing component, breaking it into small pieces to prevent blockage and high load in subsequent processing. It then falls into the reprocessing component for further crushing into particles. The processing exhaust component guides the airflow to introduce the generated debris, reducing drift pollution. Subsequently, it is filtered through the filter section of the reprocessing component. The waste that meets the requirements is filtered and discharged from the bottom outlet of the recycling shell 1, while the waste that does not meet the requirements moves through the filter section to the opening 13 and is discharged through the discharge shell 14.

[0060] The anti-accumulation component includes two symmetrically distributed telescopic swing plates 41. Each telescopic swing plate 41 includes a sleeve plate 411 and a movable plate 412. The top of the sleeve plate 411 is rotatably connected to the side wall of the feeding shell 2. The bottom of the movable plate 412 is rotatably connected to a second swing plate 42. The movable plate 412 extends into the sleeve plate 411 and is slidably connected. The bottom of the second swing plate 42 is rotatably connected to a mounting plate 43. The bottom of the mounting plate 43 is fixedly connected to the top of the recycling shell 1. A crushing roller 44 is mounted on the mounting plate 43.

[0061] Therefore, since both the telescopic swing plate 41 and the swing plate 42 are movably connected and can swing in conjunction with the transmission component, the telescopic swing plate 41 can swing. When swinging, the telescopic swing plate 41 extends and retracts, causing the material injection activity, preventing accumulation and blockage. A motor can be connected to the crushing roller 44 to drive the crushing roller 44 to rotate and initially crush the waste into small pieces, preventing the subsequent processing from being overloaded.

[0062] The transmission assembly includes mounting blocks 51 installed on both sides of the top of the recycling shell 1. A dual-shaft motor 52 is mounted on the front side of the mounting block 51 on the left side. A transmission rod 510 is rotatably connected to the mounting block 51 on the right side. Half gears 56 are fixedly connected to the front output end of the dual-shaft motor 52 and the front end of the transmission rod 510. A movable frame 54 is sleeved on the outside of the half gears 56. Several teeth 57 are installed on both sides of the inner wall of the movable frame 54. A movable rod 53 is fixedly connected to the side of the movable frame 54 closest to it. The other end of the movable rod 53 extends into the feeding shell 2 and is rotatably connected to the connection between the telescopic swing plate 41 and the swing plate 42. A transmission rod 58 is fixedly connected to the rear output end of the dual-shaft motor 52. Two sprockets 59 are mounted on the transmission rod 58. A sprocket 511 is fixedly connected to the rear end of the transmission rod 510.

[0063] Thus, by rotating the front and rear output ends of the dual-axis motor 52, the transmission rod 58 and the left half gear 56 rotate. The transmission rod 58 drives the sprocket 59 to rotate the right transmission rod 510, sprocket 511, sprocket 68, and rotating rod 62. The transmission rod 510 drives the right half gear 56 to rotate. The half gear 56, through its engagement with the tooth 57 on the moving frame 54, can drive the moving frame 54 to move back and forth. This, in turn, causes the moving rod 53 to drive the telescopic swing plate 41 and the swing plate 42 to swing back and forth, forming a movement that prevents the accumulation and blockage of injection molding waste.

[0064] The tooth body 57 meshes with the half gear 56, and one of the sprockets 59 and sprocket 511 are connected by chain drive.

[0065] Thus, the meshing of the half gear 56 and the tooth body 57 can drive the moving frame 54 to move, and the chain can drive the first sprocket 59 to rotate the second sprocket 511.

[0066] The pressing assembly includes a mounting shell 61 fixedly connected to the top center of the feeding shell 2. A rotating rod 62 is rotatably connected in the mounting shell 61. A cam 63 is fixedly connected to the outside of the rotating rod 62. A movable plate 64 is slidably connected in the mounting shell 61. A pressing rod 66 is fixedly connected to the bottom of the movable plate 64. A pressing block 67 is fixedly connected to the bottom of the pressing rod 66. A sprocket 68 is fixedly connected to the rear end of the rotating rod 62 protruding from the mounting shell 61. Springs 65 are installed on both sides of the bottom of the movable plate 64.

[0067] Thus, the sprocket 68 and the rotating rod 62 rotate through the transmission of the motor. The rotation of the rotating rod 62 drives the cam 63 to rotate, which allows the moving plate 64 to move vertically in conjunction with the reset of the spring 65 and the intermittent pressure of the rotating cam 63. This intermittently presses the injection molding waste, further assisting in the discharge of the waste and improving efficiency, eliminating the need for manual handling by staff.

[0068] Another sprocket, 59, is connected to sprocket 68 via a chain.

[0069] Therefore, by using chain drive to rotate the lever 62, the need for a power source is reduced.

[0070] The reprocessing assembly includes a sliding sleeve 111 slidably connected to a cutting rod 9. A wave groove 113 is formed around the outer wall of the cutting rod 9 at its top. Four connecting rods 112 are evenly fixedly connected to the outer side of the sliding sleeve 111. Three pressing blocks 116 are slidably connected to the cutting rod 9. Each pressing block 116 has a filter plate 114 fixedly connected to the bottom of an annular shell 3. Two filter plates 114 are insufficient to form a complete circle. The bottom of each connecting rod 112, away from the sliding sleeve 111, is fixed. A vertical rod 117 is connected to the bottom of the vertical rod 117 on the left and right sides. Two pull rods 115 are rotatably connected to the bottom of the vertical rod 117 on the left and right sides. A number of evenly distributed holes 118 are opened on the filter plate 114. A filter frame 1111 is rotatably connected to the bottom of the pull rod 115 on one side. The two filter frames 1111 are rotatably connected to the inner wall of the recycling shell 1 on the side that is far apart. A rubber tension band 1110 is installed between the ends of the filter frames 1111 that are close to each other. A filter screen 119 is installed in the filter frame 1111.

[0071] Therefore, the rotation of the cutting rod 9 driven by the motor 8 causes the cutting blade 12 to rotate and further crush the waste. Simultaneously, during crushing, the rotation of the corrugated groove 113 drives the vertical reciprocating movement of the sliding sleeve 111, which in turn causes the connecting rod 112 and the vertical rod 117 to move vertically. The vertical movement of the vertical rod 117 drives the matching pressing block 116 to move vertically, intermittently pressing the waste falling onto the filter plate 114. Waste that meets the requirements will fall directly from the outlet 118, while waste that does not meet the requirements will be better cut and crushed by the cutting blade 12 during the pressing process on the filter plate 114, without damaging the uncut waste. The shredded waste is continuously subjected to hard cutting. It is driven by the cutting blade 12 to fall from the gap between the two filter plates 114 for further cutting, reducing the cutting load. At the same time, multiple layers are set up to ensure thorough cutting, guaranteeing the safety of the device and the quality of cutting. The processed waste falls onto the filter screen 119, and those that do not meet the requirements are filtered out. While the vertical rod 117 moves vertically, it can drive the filter frame 1111 to swing vertically via the pull rod 115, which moves the waste. Those that meet the requirements will fall from the filter screen 119, and those that do not meet the requirements will be discharged from the opening 13 and then from the discharge shell 14 for classification, which is convenient for subsequent processing.

[0072] The vertical rod 117 passes through the filter plate 114. The inner walls of both sides of the connecting rod 112 are equipped with sliders that match the wave groove 113. The end of the connecting rod 112 away from the sliding sleeve 111 is fixedly connected to slider 2, which is slidably connected to the inner wall of the annular shell 3.

[0073] Therefore, by using slider one, the sliding sleeve 111 can be moved vertically as the wave groove 113 rotates, and by using slider two to limit the connecting rod 112, the vertical movement of the sliding sleeve 111 will not rotate.

[0074] The pressing block 116 includes a block 1161, a drop opening 1162, and a connecting groove 1163. The two sides of the block 1161 are provided with symmetrically distributed drop openings 1162. The middle of the block 1161 is slidably connected to the cutting rod 9. The other two sides of the block 1161 are provided with connecting grooves 1163. The top of the block 1161 is inclined towards the drop opening 1162. The drop openings 1162 on the two blocks 1161 located vertically are arranged in a cross shape. When the drop openings 1162 are distributed horizontally, the front and rear sides of the drop openings 1162 are fixedly connected to the vertical rod 117 through the connecting grooves 1163.

[0075] Thus, the connecting groove 1163 and the corresponding vertical rod 117 are fixedly connected, and the corresponding vertical rod 117 are slidably connected. The pressing round blocks 116 arranged vertically can be arranged in a cross shape. When the block 1161 is distributed to the left and right, the connecting groove 1163 is connected to the vertical rod 117 distributed to the front and back. The filter plates 114 below are distributed to the left and right. When the block 1161 is distributed to the front and back, the filter plates 114 below are distributed to the front and back, so that the waste can fall onto the corresponding filter plate 114 for processing and will not fall from the gap between the filter plates 114.

[0076] The exhaust assembly includes an exhaust fan 101 mounted on the cutting rod 9, exhaust pipes 104 installed on both sides of the top of the protective shell 7, an exhaust channel 105 opened in the wall of the annular shell 3, one bottom end of the exhaust pipe 104 is connected to the inside of the protective shell 7, and one top end of the exhaust pipe 104 is connected to the exhaust channel 105. Several exhaust ports connected to the exhaust channel 105 are opened on the top of the inner wall and the outer wall of the annular shell 3. A flexible hose 106 connected to the feeding shell 2 is connected to the top of the exhaust channel 105. The flexible hose 106 passes through the swing plate 42 and is connected to the inside of the feeding shell 2. A partition 102 is provided on the top of the motor 8. An exhaust port 103 connected to the outside is opened on the rear wall of the recycling shell 1.

[0077] Therefore, when the cutting rod 9 rotates, it drives the air intake fan 101 to rotate, thereby generating a suction force. Air is drawn in through the air intake port 1 and the hose 106 to attract the debris generated during crushing. The debris is then sent to the exhaust port 103 through the air intake channel 105 and the air intake pipe 104, and then processed by an external gas treatment device to reduce pollution.

[0078] The specific implementation method is as follows: In use, the injection molding waste is fed from the top of the feeding shell 2. The rotation of the front and rear output ends of the dual-shaft motor 52 causes the transmission rod 58 and the left half gear 56 to rotate. The transmission rod 58 drives the sprocket 59 to drive the right transmission rod 510, sprocket 511, sprocket 68, and rotating rod 62 to rotate. The transmission rod 510 drives the right half gear 56 to rotate. The half gear 56, through its engagement with the tooth 57 on the moving frame 54, can drive the moving frame 54 to move back and forth. This causes the moving rod 53 to drive the telescopic swing plate 41 and the swing plate 42 to swing back and forth. The rotation of the rotating rod 62 drives the cam 63 to rotate. The moving plate 64, in conjunction with the reset of the spring 65 and the intermittent pressure of the cam 63 during rotation, can cause the lower pressure block 67 to move vertically, intermittently pressing the injection molding waste, further assisting the feeding of the waste. A motor is connected to the crushing roller 44 to drive the crushing roller 44 to rotate and initially crush the waste into small pieces.

[0079] Subsequent waste material falls into the annular shell 3 through the opening below the crushing rollers 44. At this time, the cutting rod 9 is driven by the motor 8 to rotate, causing the cutting blade 12 to rotate and further crush the waste material. Simultaneously, during crushing, the corrugated groove 113 rotates, causing the sliding sleeve 111 to move vertically back and forth, which in turn causes the connecting rod 112 and the vertical rod 117 to move vertically. The vertical movement of the vertical rod 117 causes the matching pressing block 116 to move vertically, which can intermittently press the waste material falling on the filter plate 114. Waste material that meets the requirements will fall directly from the outlet 118, while waste material that does not meet the requirements will be pressed by the filter plate 114. The material can be better cut and crushed by the cutting blade 12, and will not be subjected to hard cutting for uncut waste. Instead, it will be driven by the cutting blade 12 to fall from the gap between the two filter plates 114 for further cutting, reducing the cutting load. At the same time, the multi-layer setting can cut thoroughly, ensuring the safety of the device and the quality of cutting. When the vertical rod 117 moves vertically, it can drive the filter frame 1111 to swing vertically through the pulling rod 115, which will cause the waste to move. The waste that meets the requirements will fall from the filter screen 119, and the waste that does not meet the requirements will be discharged from the opening 13 and then discharged from the discharge shell 14 for classification, which is convenient for subsequent processing.
