Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to a stamping die waste discharge mechanism. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. A certain amount of waste will be generated during the stamping process. In the existing stamping die manufacturing equipment, a waste discharge mechanism is provided to discharge the waste.

[0003] In the related art, a stamping die waste discharge mechanism is designed, which includes a bottom plate provided with a stamping die, a guide plate is tilted and fixed on the bottom plate, the guide plate is located directly below the stamping die, and a collection box is provided below the lowest part of the guide plate. During the stamping operation, the waste generated by the stamping will fall on the guide plate, and the waste will slide down along the guide plate under the action of its own gravity and finally fall into the collection box, thereby realizing the discharge and centralized collection of the waste.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: the directly collected waste is relatively loose and occupies a large space, which not only increases the space for subsequent waste storage, but also during the transportation process, due to the loose structure of the waste, the single loading capacity of the transportation equipment is reduced, resulting in low transportation efficiency. Summary of the invention

[0005] In order to make the discharged waste more compact, reduce the space for subsequent waste storage, and improve the transportation efficiency of the waste, the present application provides a stamping die waste discharge mechanism.

[0006] The present application provides a stamping die waste discharge mechanism that adopts the following technical solution: A waste discharge mechanism for a stamping die comprises a base provided with the stamping die, an extrusion tube is fixedly provided on the base, a material receiving port is provided on the top of the extrusion tube, and the material receiving port is located below the stamping die; a sealing plate is movably provided at one end of the extrusion tube, and a fixing component is also provided on the extrusion tube, and the fixing component is used to fix the sealing plate, and the sealing plate closes one end of the extrusion tube; an extrusion head is slidably provided inside the other end of the extrusion tube, and an extrusion drive component is provided on the extrusion tube, and the extrusion drive component is used to drive the extrusion head to slide in a direction close to or away from the sealing plate.

[0007] By adopting the above technical solution, during the stamping operation, the waste generated by the stamping die will fall into the extrusion tube through the receiving port. When a certain amount of waste accumulates in the extrusion tube, the extrusion drive assembly is started, and the extrusion drive assembly drives the extrusion head to slide along the inside of the extrusion tube in the direction of the sealing plate. Under the push of the extrusion head, the waste is squeezed in the extrusion tube, and the originally loose waste is compressed more compactly. After the waste is extruded, the fixing assembly on the sealing plate is released, and the sealing plate is removed, and the extruded waste can be taken out of the extrusion tube. The structure of the extruded waste is more compact, and the space occupied during subsequent storage is greatly reduced. In addition, during transportation, the single loading capacity of the transportation equipment can be increased, thereby effectively improving the transportation efficiency of the waste and reducing storage and transportation costs.

[0008] Preferably, the top of the blocking plate is hingedly matched with the extrusion tube, and the fixing assembly includes a locking rod, a locking buckle, and a frame rod. The locking rod is fixed to the side wall of the blocking plate, one end of the frame rod is hingedly matched with the side wall of the extrusion tube, and the locking buckle is fixedly connected to the other end of the frame rod. A locking groove is provided on the locking buckle, and the locking groove is sleeved outside the locking rod.

[0009] By adopting the above technical solution, when it is necessary to close the extruded tube, the operator rotates the plugging plate around the hinge point with the extruded tube so that the plugging plate covers one end of the extruded tube, and then rotates the frame rod, aligns the locking groove on the lock buckle with the locking rod and inserts it, and the plugging plate can be fixed. In the process of extruding the waste, the cooperation between the locking rod and the lock buckle ensures that the plugging plate firmly closes the extruded tube and prevents the waste from pushing open the plugging plate. When the waste extrusion is completed, the frame rod is rotated in the opposite direction, the lock buckle is removed from the locking rod, and the waste can push open the plugging plate.

[0010] Preferably, a movable rod is fixedly provided at one end of the frame rod away from the lock buckle, a dial is rotatably provided on the side wall of the extruded tube, and a lever is fixedly provided on the end surface of the dial. The lever can be abutted against one side of the movable rod to drive the frame rod to rotate in one direction, and the lever can also be abutted against the other side of the movable rod to drive the frame rod to rotate in another direction. A rotating part is also provided on the extruded tube, and the rotating part is used to drive the dial to rotate.

[0011] By adopting the above technical solution, when it is necessary to fix or release the lock of the blocking plate, the rotating part drives the dial to rotate. As the dial rotates, the lever on the end face of the dial will move accordingly. When the lever rotates in one direction until it abuts against one side of the movable rod, the dial continues to be rotated, and the lever will toggle the movable rod, thereby driving the frame rod to rotate in the direction of fixing the blocking plate. At this time, the lock groove on the lock buckle is inserted into the lock rod to achieve the fixation of the blocking plate. When the waste extrusion is completed and the blocking plate needs to be opened, the dial rotates in the opposite direction, and the lever rotates until it abuts against the other side of the movable rod, thereby toggling the frame rod to rotate in the direction of releasing the fixation, and the lock buckle is easily removed from the lock rod. The process that originally required manual operation of the frame rod is transformed into a process that is achieved by controlling the dial and the lever through a rotating part, which further improves the convenience and automation of the operation and reduces the labor intensity of the operator.

[0012] Preferably, the extrusion drive assembly includes a propulsion gear, a propulsion rack, and a discharge motor. The propulsion gear is rotatably arranged in the extrusion tube, the propulsion rack is fixedly connected to the extrusion head, the propulsion rack and the propulsion gear are meshed with each other, the discharge motor is fixedly connected to the extrusion tube, and the drive shaft of the discharge motor is coaxially fixed with the propulsion gear.

[0013] By adopting the above technical solution, when a certain amount of waste accumulates in the extrusion tube, the discharge motor is started, and the driving shaft of the discharge motor drives the propulsion gear to rotate synchronously. The rotation of the propulsion gear is converted into linear motion of the propulsion rack, thereby driving the extrusion head to slide in the extrusion tube in the direction close to or away from the sealing plate.

[0014] Preferably, the rotating member includes a pulley and a transmission belt, the pulley is coaxially fixed with the propulsion gear, the transmission belt is arranged for transmission between the pulley and the dial, one end of the transmission belt is sleeved on the pulley, and the other end of the transmission belt is sleeved on the dial.

[0015] By adopting the above technical solution, when the discharge motor is started and the propulsion gear rotates, the pulley fixed coaxially therewith rotates synchronously, and the pulley drives the transmission belt to operate, thereby driving the dial to rotate. This allows the two operations of squeezing waste and fixing or releasing the blocking plate to be powered by the same discharge motor, without the need for an additional power source, thereby reducing energy consumption. At the same time, the sliding of the extrusion head is linked to the activity of the lock. After the propulsion gear pushes the extrusion head to extrude the waste to a certain extent through the propulsion rack, the lever will press against one side of the movable rod, thereby driving the lock away from the lock rod; conversely, after the waste is pushed out of the extrusion tube, the blocking plate will automatically close under the action of its own weight, but the blocking plate will shake when closed, and it will take some time to restore to a stable state; in the process of the blocking plate restoring stability, the propulsion gear rotates in the opposite direction to drive the extrusion head to reset. In addition, when the extrusion head starts to slide, the lever rotates and moves away from the movable rod. When the reset sliding of the extrusion head is close to the end, the lever will contact the other side of the movable rod again, thereby pushing the lock to be re-set on the lock rod to complete the locking of the blocking plate. The orderly connection between the waste extrusion and the sealing plate is realized. When the extrusion head is reset, the sealing plate is given sufficient time to recover stability, and then the sealing plate is fixed.

[0016] Preferably, a receiving hopper is fixedly provided on the material receiving port, a gate groove is opened on the side wall of the material receiving port, a closed gate plate is slidably provided in the gate groove, the closed gate plate blocks the material receiving port, a relevant gate assembly is provided on the extrusion tube, and the closing gate assembly is used to drive the closed gate plate to slide.

[0017] By adopting the above technical solution, the setting of the receiving hopper increases the area of ​​the receiving port, making it easier for the waste generated by the stamping die to fall into the extrusion tube. When the waste in the extrusion tube is extruded and ready to be discharged, the gate assembly drives the closed gate plate to extend out of the gate slot to block the receiving port, so that when the waste is discharged, new waste can be prevented from falling into the extrusion tube during the discharge process, so that the waste is temporarily retained in the receiving hopper.

[0018] Preferably, the gate closing assembly includes a tension rope, a winding wheel, and a torsion spring. The winding wheel rotates on the side of the extrusion head away from the winding wheel. One end of the tension rope is fixedly connected to the closed gate plate, and the other end of the tension rope is fixed and wound on the winding wheel. The torsion spring is arranged between the winding wheel and the extrusion head, and the torsion spring drives the winding wheel to rotate in the direction of winding the tension rope.

[0019] By adopting the above technical solution, when the extrusion head slides toward the blocking plate in the extrusion tube to extrude the waste, the extrusion head drives the reel to slide together, and the reel pulls the closed gate plate through the tension rope to slide and block the material receiving port. After the closed gate plate blocks the material receiving port, the closed gate plate cannot continue to slide. At this time, the reel overcomes the elastic force of the torsion spring and releases the tension rope so that the extrusion head can continue to slide. When the waste extrusion is completed and the extrusion head begins to reset, the reel starts to rotate under the drive of the reset extrusion head, and gradually rewinds the released tension rope.

[0020] Preferably, the gate closing assembly also includes a return spring, one end of which is fixedly connected to the inner wall of the gate groove, and the other end of which is fixedly connected to the closed gate plate. The return spring is used to drive the closed gate plate away from the material receiving port, and the elastic force of the return spring is smaller than the elastic force of the torsion spring.

[0021] By adopting the above technical solution, since the elastic force of the reset spring is smaller than the elastic force of the torsion spring, the reset spring deforms before the torsion spring during the stage of the extrusion head extruding the waste, so the torsion spring begins to deform only when the closed gate slides to the point where it cannot move. With the torsion spring continuously providing a large restoring force, the closed gate can remain in the position of blocking the material receiving port, and new waste is prevented from entering the extrusion tube as much as possible. When the waste extrusion is completed, the extrusion head resets and drives the winding wheel to rewind the tension rope, and the reset spring provides a force for the reverse sliding of the closed gate, so that the closed gate is away from the material receiving port and the material receiving channel is opened.

[0022] Preferably, a group of crushing rollers are rotatably arranged in the receiving hopper, and a crushing driving member for driving the crushing rollers to rotate is arranged on the receiving hopper.

[0023] By adopting the above technical solution, when the waste generated by the stamping die falls into the receiving hopper, the waste will enter between the crushing rollers, and the high-speed rotating crushing rollers will crush the waste. The size of the crushed waste is greatly reduced and the shape is more regular, so that the waste can be distributed more evenly after entering the extrusion tube, and the accumulation of large-sized waste can be avoided as much as possible, resulting in uneven extrusion. Moreover, the contact between the crushed waste particles is closer, and under the action of the extrusion head, it can be compressed more tightly, further improving the compression ratio of the waste.

[0024] Preferably, the pulverizing drive component includes a first gear, a second gear, and a pulverizing motor, the first gear is coaxially fixed with one of the pulverizing rollers, the second gear is coaxially fixed with the other pulverizing roller, the first gear and the second gear are meshed with each other, the pulverizing motor is fixedly connected to the receiving hopper, and the driving shaft of the pulverizing motor is coaxially fixed with any pulverizing roller.

[0025] By adopting the above technical solution, when the crushing motor is started, the driving shaft of the crushing motor drives the crushing roller fixed coaxially therewith to rotate. Since the first gear and the second gear are meshed with each other, the rotation of the first gear will drive the second gear to rotate in the opposite direction, thereby causing the other crushing roller fixed coaxially with the second gear to start rotating. The two crushing rollers rotate at high speed in opposite directions, forming an efficient crushing working mode.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting an extrusion tube, a blocking plate, a fixing assembly, an extrusion head and an extrusion drive assembly, the waste after stamping is extruded, so that the discharged waste structure is more compact, the space for subsequent waste storage is reduced, the waste transportation efficiency is improved, and the storage and transportation costs are reduced; 2. By setting the locking rod, locking buckle, locking groove, frame rod, movable rod, dial, lever, pulley and transmission belt, the automatic operation of fixing and releasing the blocking plate is realized. When the waste is squeezed, the blocking plate is automatically unlocked, and when the punching head is reset, the blocking plate is automatically fixed; 3. By setting the receiving hopper, gate slot, closed gate, gate closing assembly, tension rope, reel, torsion spring and reset spring, ensure that new waste is prevented from entering the extrusion tube when the waste is discharged, ensure that during the waste extrusion process, the closed gate blocks the material receiving port, and the closed gate automatically resets after the waste is discharged.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a stamping die waste discharge mechanism. Figures 1 to 4 The extrusion tube 2 is a rectangular cross section in the length direction. A receiving port 21 is provided at the top of the extrusion tube 2. A receiving hopper 26 is fixed on the receiving port 21. The receiving hopper 26 and the receiving port 21 are located below the stamping die 11. Waste generated by the stamping die 11 is collected by the receiving hopper 26 and falls into the interior of the extrusion tube 2 through the receiving port 21.

[0036] Reference Figure 1 A blocking plate 22 is movably provided at one end of the extrusion tube 2. Specifically, the top of the blocking plate 22 is hingedly matched with the extrusion tube 2. A fixing assembly 3 is also provided on the extrusion tube 2. The fixing assembly 3 is used to fix the blocking plate 22. The blocking plate 22 closes one end of the extrusion tube 2. An extrusion head 23 is slidably provided inside the other end of the extrusion tube 2. An extrusion drive assembly 4 is provided on the extrusion tube 2. The extrusion drive assembly 4 is used to drive the extrusion head 23 to slide in a direction close to or away from the blocking plate 22. A guide plate is also tilted and fixed on the base 1. The highest end of the guide plate is located below the end of the extrusion tube 2 close to the blocking plate 22, and the lowest end of the guide plate extends to the outside of the base 1.

[0037] Reference Figure 1When a certain amount of waste accumulates in the extrusion tube 2, the extrusion drive assembly 4 drives the extrusion head 23 to slide in the direction of the blocking plate 22. Since the blocking plate 22 seals one end of the extrusion tube 2, the waste is squeezed in the extrusion tube 2, and the originally loose waste is compressed more compactly and forms a block. When the waste is squeezed, the fixing assembly 3 on the blocking plate 22 is released, and the extrusion head 23 pushes the waste so that the waste can push open the blocking plate 22 and push the waste out of the extrusion tube 2. The waste slides out of the base 1 along the guide plate and falls into a pre-prepared collection container.

[0038] In order to facilitate the fixing or separation of the blocking plate 22 and the extruded tube 2, refer to Figure 1 and Figure 2 The fixing assembly 3 includes a locking rod 31, a locking buckle 32, and a frame rod 33. The locking rod 31 is fixed to the side wall of the blocking plate 22, one end of the frame rod 33 is hingedly matched with the side wall of the extrusion tube 2, and the locking buckle 32 is fixedly connected to the other end of the frame rod 33. The locking buckle 32 is provided with a locking groove 321, and the locking groove 321 is sleeved outside the locking rod 31. Specifically, the locking groove 321 is provided along an arc centered on the rotation axis of the frame rod 33. By rotating the frame rod 33, the locking groove 321 on the locking buckle 32 is sleeved into or out of the locking rod 31 to achieve the fixing or separation of the extrusion tube 2 and the blocking plate 22.

[0039] Reference Figure 1 and Figure 2 A movable rod 331 is fixedly provided at one end of the frame rod 33 away from the lock buckle 32, and a dial 24 is rotatably provided on the side wall of the extrusion tube 2, and the movable rod 331 extends to the end surface of the shaft dial 24. A lever 241 is also fixedly provided on the end surface of the dial 24, and the lever 241 can abut against one side of the movable rod 331 to drive the frame rod 33 to rotate in one direction, and the lever 241 can also abut against the other side of the movable rod 331 to drive the frame rod 33 to rotate in another direction. A rotating member 25 is also provided on the extrusion tube 2, and the rotating member 25 is used to drive the dial 24 to rotate.

[0040] Reference Figure 2 and Figure 5 A limiting hole 34 is provided on the side wall of the extrusion tube 2, and a limiting ball 341 is slidably arranged in the limiting hole 34. A thrust spring 342 is arranged in the limiting hole 34, one end of the thrust spring 342 is fixedly connected to the limiting ball 341, and the other end of the thrust spring 342 is fixedly connected to the inner wall of the limiting hole 34, and the thrust spring 342 is in a relaxed state. The thrust spring 342 causes the limiting ball 341 to partially extend out of the limiting hole 34, and the volume of the portion of the limiting ball 341 extending out of the limiting hole 34 is less than or equal to one half of the total volume of the limiting ball 341. One side of the frame rod 33 can be abutted against one side of the limiting ball 341, and the other side of the frame rod 33 can be abutted against the other side of the limiting ball 341.

[0041] Reference Figures 1 to 5When the blocking plate 22 needs to be fixed or released, the rotating member 25 drives the dial 24 to rotate, and the lever 241 on the end surface of the dial 24 will move accordingly. When the lever 241 rotates in one direction until it contacts one side of the movable rod 331, the dial 24 continues to be rotated, and the lever 241 will move the movable rod 331, and the movable rod 331 drives the frame rod 33 to rotate. The frame rod 33 contacts the limiting ball 341, squeezes the limiting ball 341 into the limiting hole 34, and the thrust spring 342 contracts. After the frame rod 33 passes over the limiting ball 341, the limiting ball 341 is reset under the action of the thrust spring 342. At this time, the lock groove 321 on the lock buckle 32 is inserted into the lock rod 31 to achieve the fixing of the blocking plate 22. When the waste material is squeezed out and the blocking plate 22 needs to be opened, the dial 24 rotates in the opposite direction, and the lever 241 rotates to abut against the other side of the movable rod 331, thereby driving the frame rod 33 to rotate in the direction of releasing the fixation, and removing the lock buckle 32 from the lock rod 31. In the process of the lever 241 and the movable rod 331 being out of contact, under the restraint of the stop ball 341, if the movable rod 331 does not apply external force interference, the frame rod 33 cannot rotate automatically and remains in a stable state.

[0042] In order to drive the extrusion head 23 to slide, refer to Figure 1 and Figure 4 The extrusion drive assembly 4 includes a propulsion gear 41, a propulsion rack 42, and a discharge motor 43. The propulsion gear 41 is rotatably arranged in the extrusion tube 2, the propulsion rack 42 is fixedly connected to the extrusion head 23, and the propulsion rack 42 and the propulsion gear 41 are meshed with each other. The discharge motor 43 is fixedly connected to the extrusion tube 2, and the driving shaft of the discharge motor 43 is coaxially fixed with the propulsion gear 41. When a certain amount of waste is accumulated in the extrusion tube 2, the discharge motor 43 drives the propulsion gear 41 to rotate, and the propulsion gear 41 drives the propulsion rack 42 to slide, thereby driving the extrusion head 23 to slide in the extrusion tube 2 in the direction close to or away from the blocking plate 22.

[0043] In order to drive the dial 24 to rotate automatically, refer to Figures 1 to 5 A groove is provided on the peripheral wall of the dial 24, and the rotating member 25 includes a pulley 251 and a transmission belt 252. The pulley 251 is coaxially fixed with the propulsion gear 41, and the transmission belt 252 is arranged for transmission between the pulley 251 and the dial 24. One end of the transmission belt 252 is sleeved on the pulley 251, and the other end of the transmission belt 252 is sleeved on the groove of the dial 24.

[0044] Reference Figures 1 to 5When the propulsion gear 41 rotates, the sliding of the extrusion head 23 is linked to the activity of the lock 32. After the propulsion gear 41 pushes the extrusion head 23 to extrude the waste to a certain extent through the propulsion rack 42, the lever 241 will contact one side of the movable rod 331, thereby driving the lock 32 away from the lock rod 31. After the waste is pushed out of the extrusion tube 2, the blocking plate 22 will automatically close under the action of its own weight, but the blocking plate 22 will shake when closing, and it will take some time to restore to a stable state. In the process of the blocking plate 22 restoring stability, the propulsion gear 41 rotates in the opposite direction to drive the extrusion head 23 to reset. And in the process of the extrusion head 23 starting to slide, the lever 241 rotates and moves away from the movable rod 331. When the reset sliding of the extrusion head 23 is close to the end, the lever 241 will contact the other side of the movable rod 331 again, thereby pushing the lock 32 to be re-set on the lock rod 31, completing the locking of the blocking plate 22. While the extrusion head 23 is being reset, the blocking plate 22 is given sufficient time to recover stability. When the extrusion head 23 is about to be completely reset, the stable blocking plate 22 is fixed.

[0045] In order to prevent new waste from entering the extrusion tube 2 from the material receiving port 21 when extruding waste, refer to Figure 1 and Figure 6 A gate groove 211 is provided on the side wall of the material receiving port 21, and a closed gate plate 212 is slidably provided in the gate groove 211. The closed gate plate 212 can block the material receiving port 21. A gate assembly 5 is provided on the extrusion tube 2, and the gate closing assembly 5 is used to drive the closed gate plate 212 to slide. Among them, the gate closing assembly 5 includes a tension rope 51, a winding wheel 52, a torsion spring 53, and a reset spring 54. A movable groove connected to the gate groove 211 is provided on the extrusion tube 2 on the side of the material receiving hopper 26, and a pile rod is slidably provided in the movable groove, and the pile rod is fixedly connected to the closed gate plate 212. The winding wheel 52 rotates on the side of the extrusion head 23 away from the winding wheel 52. One end of the tension rope 51 is fixedly connected to the closed gate plate 212 through the pile rod, and the other end of the tension rope 51 is fixed and wound on the winding wheel 52. The torsion spring 53 is arranged between the winding wheel 52 and the extrusion head 23, and the torsion spring 53 drives the winding wheel 52 to rotate in the direction of winding the tension rope 51. One end of the return spring 54 is fixedly connected to the inner wall of the gate groove 211, and the other end of the return spring 54 is fixedly connected to the closed gate plate 212. The return spring 54 is used to drive the closed gate plate 212 away from the material receiving port 21, and the elastic force of the return spring 54 is smaller than the elastic force of the torsion spring 53.

[0046] Reference Figure 1 and Figure 6When the extrusion head 23 slides toward the blocking plate 22 in the extrusion tube 2 to extrude the waste, the reel 52 moves with the extrusion head 23. Since the elastic force of the torsion spring 53 is greater than the elastic force of the reset spring 54, the reel 52 pulls the tension rope 51 and drives the closed gate plate 212 to slide in the gate groove 211 through the pile rod to block the material receiving port 21. After the closed gate plate 212 blocks the material receiving port 21, the closed gate plate 212 cannot move further, and the extrusion head 23 needs to continue to move forward. At this time, the reel 52 overcomes the elastic force of the torsion spring 53 to release the tension rope 51 to ensure that the extrusion head 23 can continue to complete the waste extrusion action. When the waste extrusion is completed, the extrusion head 23 begins to reset, and the reel 52 first rotates in the opposite direction to rewind the tension rope 51. After the torsion spring 53 is released, the return spring 54 pushes the closing gate 212 to slide in the opposite direction in the gate groove 211 , so that the closing gate 212 moves away from the material receiving port 21 , opens the material receiving channel, and allows new waste to enter the extrusion tube 2 .

[0047] To improve the compression effect of waste, refer to Figure 3 and Figure 4 A group of crushing rollers 261 are rotatably arranged in the receiving hopper 26, and a crushing driving member 6 for driving the crushing rollers 261 to rotate is arranged on the receiving hopper 26. The crushing driving member 6 includes a first gear 61, a second gear 62, and a crushing motor 63. The first gear 61 is coaxially fixed to one of the crushing rollers 261, the second gear 62 is coaxially fixed to the other crushing roller 261, the first gear 61 and the second gear 62 are meshed with each other, the crushing motor 63 is fixedly connected to the receiving hopper 26, and the driving shaft of the crushing motor 63 is coaxially fixed to any crushing roller 261. During the stamping operation, after the waste generated by the stamping die 11 falls into the receiving hopper 26, the crushing motor 63 is driven by the meshing of the first gear 61 and the second gear 62, so that the two crushing rollers 261 rotate in opposite directions, and a shear force is formed between the two crushing rollers 261 to crush the waste. The size of the crushed waste becomes smaller and the shape becomes more regular. The crushed waste particles are in closer contact with each other and can be compressed more tightly under the action of the extrusion head 23, further improving the compression ratio of the waste.

[0048] The implementation principle of the waste discharge mechanism of the stamping die 11 in the embodiment of the present application is as follows: during the stamping operation, the waste generated by the stamping die 11 will fall into the receiving hopper 26 below, and the waste will be crushed by a group of crushing rollers 261 in the receiving hopper 26, and then transported to the inside of the extrusion tube 2 through the receiving port 21. As the waste continues to accumulate in the extrusion tube 2, when it reaches a certain amount, the discharge motor 43 is started. The driving shaft of the discharge motor 43 drives the propulsion gear 41 to rotate, and since the propulsion gear 41 and the propulsion rack 42 are meshed with each other, the extrusion head 23 is driven to slide in the extrusion tube 2 toward the blocking plate 22.

[0049] While the extrusion head 23 is sliding, on the one hand: the reel 52 pulls the tension rope 51, and drives the closed gate plate 212 to slide in the gate groove 211 through the pile rod, and the closed gate plate 212 blocks the material receiving port 21 to prevent new waste from entering the extrusion tube 2 during the extrusion process. When the closed gate plate 212 completely blocks the material receiving port 21 and cannot move further, and the extrusion head 23 needs to continue to move forward, the reel 52 overcomes the elastic force of the torsion spring 53 and releases the tension rope 51, so that the extrusion head 23 can continue to complete the waste extrusion action. On the other hand: the pulley 251 coaxially fixed with the propulsion gear 41 also rotates accordingly, and the pulley 251 drives the dial 24 to rotate through the transmission belt 252. After the pushing gear 41 pushes the extrusion head 23 to extrude the waste to a certain extent through the pushing rack 42, the lever 241 on the end surface of the dial 24 abuts against one side of the movable rod 331, and then the movable rod 331 is pushed to rotate the frame rod 33, and the lock buckle 32 is removed from the lock rod 31, thereby releasing the fixing of the blocking plate 22. The extrusion head 23 pushes the waste to push open the blocking plate 22, and the waste slides out of the base 1 along the guide plate and falls into a pre-set collection container.

[0050] The blocking plate 22 automatically closes under the action of its own weight, but it will shake when closing, and it takes some time to restore to a stable state. At the same time, the discharge motor 43 reverses, causing the propulsion gear 41 to rotate in the opposite direction, driving the extrusion head 23 to reset. During the process of the extrusion head 23 starting to reset and slide, the lever 241 rotates and moves away from the movable rod 331. The winding wheel 52 first rotates in the opposite direction to rewind the tension rope 51. After the elastic force of the torsion spring 53 is released, the elastic force of the reset spring 54 pushes the closed gate plate 212 to slide in the opposite direction in the gate groove 211, so that the closed gate plate 212 is away from the material receiving port 21, opening the material receiving channel so that new waste can enter the extrusion tube 2. When the reset and sliding of the extrusion head 23 is close to the end, the blocking plate 22 has restored stability, and the lever 241 rotates with the dial 24 to contact the other side of the movable rod 331 again, pushing the frame rod 33 to rotate, so that the lock buckle 32 is re-sleeved on the lock rod 31, completing the locking of the blocking plate 22, and preparing for the next waste extrusion and discharge.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
