Abstract

This invention discloses a shell processing device for microwave oven high-voltage transformer production, relating to the field of transformer shell processing technology. The device includes a shell, inside which a feeding plate is installed. A crushing roller for crushing the shell is positioned above the feeding plate. An adjustment mechanism for assisting in the crushing process is also located inside the shell. Waste material is squeezed by a pressing roller below the mounting plate, facilitating subsequent crushing by the crushing roller. Furthermore, the coordinated movement of a pusher plate and a guide plate ensures the waste material moves evenly and smoothly to the pressing roller for crushing, effectively preventing insufficient contact between the waste material and the crushing roller, thus improving the crushing effect. The sliding plate also pre-processes the waste material to some extent, reducing energy consumption from subsequent pusher plate processing and increasing the utilization rate of the pusher plate.

Description

Technical Field

[0001] This invention relates to the field of transformer casing processing technology, and more particularly to a casing processing device for the production of microwave oven high-voltage transformers. Background Technology

[0002] The microwave oven high-voltage transformer is one of the core electrical components of a microwave oven. Its core function is to convert household mains electricity into the high voltage and low current required by the microwave oven magnetron, while providing filament heating voltage and providing the basic conditions for microwave generation. It is the core hub for the microwave oven to realize the conversion of "electrical energy → high-voltage electrical energy → microwave energy". The outer shell of a microwave oven high-voltage transformer is a protective structure that wraps around the transformer core, windings, and other core electrical components. Its main function is to isolate the internal high-voltage components, prevent mechanical damage and foreign object intrusion, and assist in heat dissipation. It is a key auxiliary component to ensure the safe operation of the transformer and the safety of user operation.

[0003] In the current technology, engineering plastics are usually used as raw materials in the production process of microwave oven high voltage transformer shells. Since the core process of shell production is injection molding, problems such as mold wear and deviations in injection parameters (temperature, pressure) may occur during shell production, resulting in some shells having surface cracks, dimensional deviations, and substandard insulation performance. Therefore, in order to recycle substandard waste materials, it is necessary to crush the waste materials and then mix the crushed waste materials with new materials for re-injection molding, which can reduce production costs. However, during the crushing process of waste materials using a crusher, the waste materials after injection molding have high mechanical strength, impact resistance, and are not easily deformed. If the waste materials are directly fed into the crusher for crushing, too much waste material may cause blockage, resulting in some waste material not being completely crushed. If too little waste material is fed into the crusher, it may not be able to make sufficient contact with the crushing rollers. This results in uneven size of the crushed material, which cannot meet the requirements for reuse. Consequently, it affects the effect of subsequent mixing with new engineering plastic particles, and the quality of the re-injection molded shell will not meet the standards. To address this, we propose a shell processing device for microwave oven high-voltage transformer production. Summary of the Invention

[0004] To address the issue that injection-molded waste materials, due to their high mechanical strength, impact resistance, and resistance to deformation, may not fully contact the crushing rollers, resulting in unevenly sized fragments that fail to meet reuse requirements, this invention employs the following technical solution: A shell processing device for microwave oven high voltage transformer production includes a shell, a feeding plate installed inside the shell, a crushing roller for crushing the shell arranged above the feeding plate, and an adjustment mechanism for assisting the crushing of the shell inside the shell. The adjustment mechanism includes a movable mounting plate. Two sets of extrusion rollers for extruding the outer shell are arranged below the mounting plate. An auxiliary mechanism is arranged above the feeding plate. The auxiliary mechanism includes a swing telescopic rod rotatably connected to the mounting plate. A pusher plate is fixedly connected to one end of the swing telescopic rod, and the swing telescopic rod and the pusher plate are arranged in a T-shape. Guide plates are rotatably connected to both sides of the pusher plate through pins.

[0005] Preferably, the adjustment mechanism further includes a motor, the output end of which is fixedly connected to a screw, and a movable plate is threadedly connected to the surface of the screw. The lower part of the movable plate is fixedly connected to the mounting plate. Both of the extrusion rollers are inclined, and the height of the extrusion roller closer to the crushing roller is lower than the height of the extrusion roller closer to the pusher plate.

[0006] Preferably, a cover plate is fixedly connected to the lower part of the motor, the cover plate is fixedly installed on the upper part of the outer casing, a partition is provided between the movable plate and the cover plate, a screen is provided on the feeding plate directly below the crushing roller, and a baffle plate is provided on the outer side of the crushing roller that is detachably connected to the outer casing.

[0007] Preferably, the auxiliary mechanism further includes two protrusions fixed to the inner side of the housing. The surfaces of the protrusions are in slidable contact with a movable slide rod. The middle position of the movable slide rod near the pusher plate is set as an arc surface. The arc surface of the movable slide rod is in slidable contact with a top rod. One end of the top rod is fixedly connected to a fixing rod. The two ends of the fixing rod are slidably engaged with the inner side of the guide plate.

[0008] Preferably, a material feeding mechanism for moving waste material is provided above the feeding plate. The material feeding mechanism includes a rotating cylinder located directly above the feeding plate. A fixed cylinder is fixedly connected inside the rotating cylinder. Multiple elastic levers are fixedly connected to the outside of the fixed cylinder. A transmission rod is sleeved inside the rotating cylinder and the fixed cylinder.

[0009] Preferably, gears are fixedly connected to both ends of the transmission rod, a rack is meshed above the gears, a movable telescopic rod is fixedly connected to one end of the rack, one end of the movable telescopic rod is fixedly connected to the mounting plate, and the rack and the feed plate are telescopically connected.

[0010] Preferably, a cooperating mechanism for assisting the feeding mechanism in feeding waste material is also provided above the feeding plate. The cooperating mechanism includes a cam fixed to the rotating cylinder, a sliding column slidingly contacting the surface of the cam, and a sliding plate detachably connected to one end of the sliding column.

[0011] Preferably, the convex disc and multiple elastic levers are staggered on the surface of the rotating cylinder. The surface of the convex disc has a groove that matches one end of the sliding column.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The extrusion rollers below the mounting plate compress the waste material, facilitating subsequent crushing by the crushing rollers. The coordinated movement of the pusher plate and guide plate ensures that the waste material moves to the extrusion rollers in a uniform and stable manner, effectively preventing insufficient contact between the waste material and the crushing rollers and improving the crushing effect.

[0015] 2. By setting up the feeding mechanism and the cooperating mechanism, the effect of waste treatment can be improved, and the waste can be prevented from affecting the operation of the pusher plate and the guide plate. The waste can be fully processed by the pusher plate, and the operation of the sliding plate can also pre-treat the waste to a certain extent, which can reduce the energy consumption of the subsequent pusher plate for waste treatment and improve the utilization rate of the pusher plate.

[0016] In summary, this invention overcomes the shortcomings of the prior art and has high social value and application prospects. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments 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. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0021] Example 1: Refer to Figures 1 to 6A shell processing device for microwave oven high voltage transformer production includes a shell 1, a feeding plate 4 installed inside the shell 1, a crushing roller 3 for crushing the shell is arranged above the feeding plate 4, and an adjustment mechanism 2 for assisting the crushing of the shell is arranged inside the shell 1. The adjustment mechanism 2 includes a movable mounting plate 204. Two sets of extrusion rollers 205 for extruding the outer shell are arranged below the mounting plate 204. An auxiliary mechanism 5 is arranged above the feeding plate 4. The auxiliary mechanism 5 includes a swing telescopic rod 501 rotatably connected to the mounting plate 204. One end of the swing telescopic rod 501 is fixedly connected to a pusher plate 502. The swing telescopic rod 501 and the pusher plate 502 are arranged in a T-shape. Guide plates 507 are rotatably connected to both sides of the pusher plate 502 through pins.

[0022] This invention takes into account that, in order to avoid waste of raw materials and increased production costs, it is necessary to crush substandard waste materials into qualified fragments, and then mix the fragments with new engineering plastic granules and re-injection mold them. This can effectively reduce waste of raw materials and increase production costs. However, since the microwave oven high-voltage transformer shell made of engineering plastic has the characteristics of high mechanical strength, impact resistance, and non-deformation, if the waste materials are directly fed to the crushing roller 3 for crushing, too much waste material may cause blockage of the feed, making it impossible for the crushing roller 3 to fully crush the waste material. Some waste material may not be reusable after crushing. On the other hand, too little waste material will reduce the squeezing and shearing contact area of ​​the crushing roller 3 with the waste material, and the waste material may not be able to effectively contact the crushing roller 3. Therefore, by setting two extrusion rollers 205 inside the outer shell 1, when the waste shell is fed into the outer shell 1 through the feeding plate 4, the shell will be flattened by the rotational extrusion force of the extrusion rollers 205. The flattened waste will be crushed by the high-speed rotation of the crushing rollers 3. Since the mounting plate 204 inside the outer shell 1 can adjust the distance between itself and the feeding plate 4, it can extrude waste of different sizes at the same time and adjust the extrusion force on the waste. To a certain extent, it can destroy the characteristics of the waste shell supported by engineering plastic particles, so that the subsequent crushing rollers 3 can crush the waste better. It should be noted that when the waste material is fed into the feeding plate 4, the frequency of movement of the mounting plate 204 inside the outer casing 1 can be adjusted to quickly and stably cause the two extrusion rollers 205 to extrude the waste material. At this time, the adjustment movement of the mounting plate 204 can drive the pusher plate 502 at one end of the swing telescopic rod 501 to reciprocate. When the waste material is fed into the feeding plate 4, the swing telescopic rod 501 drives the pusher plate 502 to move to the left on the surface of the feeding plate 4 (e.g., ...). Figure 3As shown, the position away from the crushing roller 3 is positioned on the left. At this time, the movement of the pusher plate 502 can disperse the waste material falling inside the feed plate 4, so that the waste material moves from the surface and both sides of the pusher plate 502 towards the crushing roller 3. This can prevent the waste material from clumping together after being put into the feed plate 4. Instead, the waste material moves towards the extrusion roller 205 in a piled-up state, which makes it easier for the extrusion roller 205 to extrude it, thereby improving the crushing effect of the subsequent crushing roller 3. It should be noted again that since both the pusher plate 502 and the discharge plate 4 are inclined, when the swing telescopic rod 501 drives the pusher plate 502 to move to the right on the surface of the discharge plate 4, the angle between the pusher plate 502 and the surface of the discharge plate 4 will change, making the angle between the pusher plate 502 and the surface of the discharge plate 4 smaller. Therefore, the pusher plate 502 will be more inclined on the surface of the discharge plate 4. When the waste inside the discharge plate 4 moves and comes into contact with the pusher plate 502, the waste will be more easily moved from the surface and sides of the pusher plate 502 to the position of the extrusion roller 205 for extrusion. This allows the waste to be extruded by the extrusion roller 205 in a uniform and gentle motion, thereby improving the crushing effect of the subsequent crushing roller 3 on the extruded waste. It should be further explained that, since the pusher plate 502 and the two extrusion rollers 205 are moving towards the crushing roller 3, the two guide plates 507 on both sides of the pusher plate 502 will open intermittently during the movement. At this time, the two guide plates 507 can effectively prevent the waste from moving too fast after the pusher plate 502 gets closer to the discharge plate 4, causing the waste to become excessively dispersed and affecting the extrusion rollers 205's compression. Furthermore, since the swing telescopic rod 501 and the pusher plate 502 are T-shaped, when the guide plates 507... When the pusher plate 502 oscillates intermittently around the pin on both sides, the area of ​​the pusher plate 502 changes between increasing and decreasing during the movement. This not only avoids affecting the movement of waste material on both sides or the surface of the pusher plate 502, but also pushes the waste material that crosses the position of the pusher plate 502 during the movement of the pusher plate 502, applying a certain amount of extrusion force. This allows the waste material to fully and evenly contact the extrusion roller 205, so that the extrusion roller 205 can fully extrude it, improving the crushing effect of the subsequent crushing roller 3.

[0023] Reference Figures 2 to 3 The adjustment mechanism 2 also includes a motor 201. The output end of the motor 201 is fixedly connected to a screw 202. A movable plate 203 is threadedly connected to the surface of the screw 202. The lower part of the movable plate 203 is fixedly connected to the mounting plate 204. Both extrusion rollers 205 are inclined. The height of the extrusion roller 205 near the crushing roller 3 is lower than the height of the extrusion roller 205 near the pusher plate 502.

[0024] During operation, when the position of the mounting plate 204 needs to be adjusted so that the waste material can be effectively squeezed by the two extrusion rollers 205 below it, making it convenient for the subsequent crushing roller 3 to crush it, the motor 201 rotates to drive the screw 202 to rotate. The screw 202 drives the moving plate 203 to move. The movement of the moving plate 203 can drive the mounting plate 204 and the two extrusion rollers 205 below it to reciprocate above the feeding plate 4. At this time, by making the height of the extrusion roller 205 near the crushing roller 3 lower than the height of the extrusion roller 205 near the push plate 502, after the waste material is initially squeezed by the extrusion roller 205 on the left, the height of the waste material will change. The extrusion roller 205 on the right, which is slightly lower in height, can still effectively squeeze the waste material. At this time, the rotation of the two extrusion rollers 205 can also transport the squeezed waste material so that the waste material can effectively reach the position of the crushing roller 3 and be crushed by the crushing roller 3. It should be noted that, since the swing telescopic rod 501 is telescopic, when the mounting plate 204 drives the swing telescopic rod 501 to move via the pin, the swing telescopic rod 501 will only drive the pusher plate 502 to move on the surface of the feed plate 4 when it reaches the maximum telescopic length (meaning the telescopic length of the swing telescopic rod 501 is limited and has reached its maximum telescopic length, at which point it will no longer telescopic). This effectively prevents the waste from being directly fed into the machine. If the angle between the pusher plate 502 and the feed plate 4 is reduced, the waste may move rapidly toward the position of the extrusion roller 205, causing the extrusion roller 205 to be unable to effectively extrude the waste, thus affecting the crushing effect of the subsequent crushing roller 3. This further improves the extrusion effect of the extrusion roller 205 and enhances the uniformity of the crushing by the subsequent crushing roller 3.

[0025] Reference Figures 1 to 3 A cover plate 9 is fixedly connected to the lower part of the motor 201. The cover plate 9 is fixedly installed on the upper part of the outer shell 1. A partition is provided between the moving plate 203 and the cover plate 9. A screen is provided on the feeding plate 4 located directly below the crushing roller 3. A baffle 8 is provided on the outer side of the crushing roller 3 and is detachably connected to the outer shell 1.

[0026] During operation, when the moving plate 203 is driven by the screw 202 to slide inside the cover plate 9 above the outer shell 1, two sets of sliding plates are set on both sides of the moving plate 203. The sliding plates are slidably connected to the cover plate 9, which can improve the stability of the moving plate 203 sliding inside the cover plate 9 and avoid affecting the stability of the moving adjustment of the mounting plate 204. In addition, by setting a screen on the feeding plate 4 directly below the crushing roller 3, when the crushed waste comes into contact with the crushing roller 3 and is crushed, the waste fragments that meet the standard will fall directly from the screen on the feeding plate 4 directly below the crushing roller 3 into the discharge channel below the outer shell 1, which is convenient for subsequent waste collection. It should be noted that when the mounting plate 204 drives the pusher plate 502 to move away from the crushing roller 3 via the swing telescopic rod 501, the feed inlet of the discharge plate 4 is set in a conical shape (e.g., Figure 2 and Figure 3 As shown in the diagram, after the waste material is fed into the feed plate 4, it will slightly gather on the surface of the feed plate 4 under the influence of the conical feed inlet and move towards the extrusion roller 205. At this time, the pusher plate 502 moves to the feed inlet of the feed plate 4, so that the pusher plate 502 is located directly to the side of the feed inlet of the feed plate 4. When the waste material comes into contact with the pusher plate 502, it will be directly dispersed and move towards the extrusion roller 205 in a relatively uniform and dispersed state. At this time, the swing telescopic rod 501 is subjected to the pressure of the pusher plate 502. After the push of the loading plate 204, the angle between the swing telescopic rod 501 and the upper surface of the feeding plate 4 will be changed again, making the angle between the swing telescopic rod 501 and the feeding plate 4 larger. When the waste moves inside the feeding plate 4 and comes into contact with the surface of the push plate 502, the push plate 502 can not only better disperse the waste, but also prevent the waste from being excessively dispersed, so that the extrusion roller 205 cannot effectively extrude the waste. This can effectively improve the pre-treatment effect of the extrusion roller 205 on the waste. It should be reiterated that when the swing telescopic rod 501 drives the pusher plate 502 to move to the position of the conical feed port of the lower plate 4, the guide plates 507 on both sides of the pusher plate 502 will also open intermittently during its movement. This causes the area on the surface of the lower plate 4 where the pusher plate 502 moves to increase and decrease, which can effectively prevent the waste from being excessively dispersed by the pusher plate 502 and prevent the waste from moving to the position of the extrusion roller 205 in an excessively dispersed state, thus affecting the extrusion effect of the extrusion roller 205. At the same time, the intermittent movement of the guide plates 507 can also push the waste that is crossing the position of the pusher plate 502 to the sides of the pusher plate 502 to a certain extent, so that the waste moving to the position of the extrusion roller 205 is more uniform, and the extrusion roller 205 can extrude the waste more evenly, which is convenient for the subsequent crushing roller 3 to crush the extruded waste.

[0027] Reference Figures 1 to 6The auxiliary mechanism 5 also includes two protrusions 504 fixed inside the outer casing 1. The surface of the protrusions 504 has a sliding contact with a movable slide rod 503. The middle position of the movable slide rod 503 near the pusher plate 502 is set as an arc surface. The arc surface of the movable slide rod 503 has a sliding contact with a top rod 505. One end of the top rod 505 is fixedly connected to a fixing rod 506. Both ends of the fixing rod 506 are slidably engaged with the inner surface of the guide plate 507.

[0028] The present invention also considers that when the mounting plate 204 drives the pusher plate 502 to move back and forth on the surface of the feed plate 4 via the swing telescopic rod 501 to disperse and slightly gather the waste material fed into the conical feed port of the feed plate 4, some of the waste material may, due to its own characteristics, come into contact with the pusher plate 502 and the moving slide rod 503 and cannot move to the position of the extrusion roller 205 to be extruded. At the same time, when some waste material moves from both ends of the pusher plate 502 to the position of the extrusion roller 205, it may cause some material to become blocked on both sides of the moving pusher plate 502 as the swing telescopic rod 501 continuously changes the angle between itself and the upper surface of the feed plate 4, thus affecting the subsequent extrusion roller 205 to extrude it. Therefore, by opening a groove inside the swing telescopic rod 501 and slidingly engaging the movable slide rod 503 inside the groove, since the telescopic movement of the swing telescopic rod 501 has a limit position, the movement of the swing telescopic rod 501 will drive the movable slide rod 503 to move. During the movement, the two ends of the movable slide rod 503 will contact the protrusion 504. At this time, the movable slide rod 503 will be squeezed and pushed by the protrusion 504 to reciprocate in the groove opened inside the swing telescopic rod 501. The reciprocating movement of the movable slide rod 503 will push the top rod 505 to slide inside the push plate 502 through the arc surface near the push plate 502. The sliding of the top rod 505 will drive the fixed rod 506 to push the guide plate 507 to swing around the pin on both sides of the push plate 502. At this time, the swing of the guide plate 507 can intermittently push the material on both sides of the push plate 502, so that the material moves towards the position of the extrusion roller 205 in a uniform state. It should be noted that when the pusher plate 502 is about to move to the position of the conical feed inlet of the feed plate 4, after the swing telescopic rod 501 has completed its telescopic movement, the moving slide rod 503 no longer reciprocates within the groove opened by the swing telescopic rod 501. At this time, the guide plate 507 will be in the closed state (e.g., Figure 6 As shown), at this time, the area of ​​the pusher plate 502 is at its minimum and located at the conical feed inlet of the feed plate 4. When the waste is put into the interior of the feed plate 4, the waste will be directly dispersed by the pusher plate 502, which can effectively prevent the waste from clumping together and moving inside the feed plate 4, affecting the subsequent extrusion roller 205 to extrude it, and the crushing roller 3 to crush the extruded waste. It should be reiterated that by setting the contact surface between the protrusion 504 and the movable slide bar 503 to be arc-shaped, and the concave surfaces of the two movable slide bars 503 being staggered, and also setting the position of the movable slide bar 503 near the push plate 502 to be arc-shaped, the two ends of the movable slide bar 503 can fully contact the arc surface of the protrusion 504 when moving, thus improving the stability of the movable slide bar 503 sliding within the groove opened in the swing telescopic rod 501, and the arc surface on one side of the movable slide bar 503 can also be aligned with the top. The rod 505 performs the extrusion operation, improving the stability of the push rod 505 reciprocating within the push plate 502. This effectively increases the force of the guide plate 507 as it intermittently opens and closes on both sides of the push plate 502. As a result, the guide plate 507 can not only move the waste material moving on both sides of the push plate 502 to prevent blockage, but also allow the push plate 502 to fully gather and evenly disperse the waste material, thus improving the extrusion effect of the extrusion roller 205 on the waste material.

[0029] Example 2: Refer to Figures 7 to 11 Above the feed plate 4 is a feeding mechanism 6 for moving waste material. The feeding mechanism 6 includes a rotating cylinder 605 located directly above the push plate 502. A fixed cylinder 607 is fixedly connected inside the rotating cylinder 605. Multiple elastic levers 606 are fixedly connected to the outside of the fixed cylinder 607. A transmission rod 604 is sleeved inside the rotating cylinder 605 and the fixed cylinder 607.

[0030] The present invention also fully considers that when the guide plate 507 is intermittently opened during the movement of the push plate 502, the guide plate 507 can change the area of ​​the push plate 502 when it moves on the upper surface of the feed plate 4 to a certain extent. At this time, the waste may be unable to effectively disperse the clumps of waste or slightly gather the excessively dispersed waste due to the change in area during the movement of the push plate 502, thereby affecting the extrusion effect of the extrusion roller 205 on the waste. Therefore, when the mounting plate 204 drives the pusher plate 502 to move towards the position of the crushing roller 3 via the swing telescopic rod 501, the gear 603 will rotate 120° clockwise, causing the rotating cylinder 605 and the fixed cylinder 607 to rotate. The rotation of the fixed cylinder 607 will cause the multiple elastic levers 606 on its surface to rotate. Since the elastic levers 606 are located directly above the pusher plate 502, the rotation of the elastic levers 606 will push away some of the waste material remaining on the surface of the pusher plate 502 and the swing telescopic rod 501, allowing the waste material to be removed from the pusher plate 502. The material continues to move towards the position of the extrusion roller 205 on both sides, which can prevent a large amount of waste material from accumulating on the surface of the pusher plate 502 after the area has been changed. This would affect the normal swinging effect of the guide plate 507 around the pin on both sides of the pusher plate 502, and affect the pushing effect of the guide plate 507 on the lungs on both sides of the pusher plate 502. As a result, the waste material cannot move towards the position of the extrusion roller 205 evenly and stably across the position of the pusher plate 502. At this time, the elastic lever 606 can move it, further improving the effect of the pusher plate 502 on the subsequent dispersion of waste material. It should be noted that, since one end of the elastic lever 606 is fixedly connected to the surface of the fixed cylinder 607, and the number of elastic levers 606 near the pusher plate 502 is greater than the number of elastic levers 606 near the mounting plate 204, the elastic levers 606 near the pusher plate 502 can move the waste material above the pusher plate 502 when rotating in both directions at 120°, causing the waste material to move to both sides of the pusher plate 502. Furthermore, when the elastic lever 606 rotates, the elastic lever 606 near the mounting plate 204 will interact with the swing telescopic rod 501. When the upper surface is in contact, a small number of elastic levers 606 are in contact with the surface of the swing telescopic rod 501 to support it. Since the elastic levers 606 are elastically set on the surface of the fixed cylinder 607, they can, to a certain extent, prevent the fixed cylinder 607 from driving multiple elastic levers 606 to move the waste material on the surface of the pusher plate 502 during rotation, thus avoiding interference between the elastic levers 606 and the pusher plate 502 and affecting the normal operation of the pusher plate 502 and the elastic levers 606. This can effectively improve the working effect of the pusher plate 502 in continuing to fully and slightly gather the waste material.

[0031] Reference Figures 7 to 8 The transmission rod 604 is fixedly connected to both ends of a gear 603. A rack 602 is meshed above the gear 603. A movable telescopic rod 601 is fixedly connected to one end of the rack 602. One end of the movable telescopic rod 601 is fixedly connected to the mounting plate 204. The rack 602 and the unloading plate 4 are telescopically connected.

[0032] During operation, when the mounting plate 204 moves, it drives the telescopic rod 601 to move, which in turn drives the rack 602 to move. The rack 602 meshes with the gear 603, which in turn drives the rotating cylinder 605 and the fixed cylinder 607 to rotate via the transmission rod 604. The rotation of the fixed cylinder 607 drives multiple elastic levers 606 to rotate 120° in both directions, thereby moving the waste material on the surface of the pusher plate 502 and improving the utilization rate of the pusher plate 502 in waste material processing. It should be noted that by setting a fixed sliding shell on the surface of the transmission rod 604, with one end of the fixed sliding shell being fixedly connected to the tapered feed plate 4 and the other end being slidably engaged with the movable telescopic rod 601, effective support can be provided for the rotation of the transmission rod 604, the movement of the movable telescopic rod 601 and the rack 602.

[0033] Reference Figures 8 to 9 Above the feeding plate 4, there is also a cooperating mechanism 7 for assisting the feeding mechanism 6 in feeding waste materials. The cooperating mechanism 7 includes a cam 701 fixed to the rotating cylinder 605. The surface of the cam 701 is in sliding contact with a sliding column 702. One end of the sliding column 702 is detachably connected to a sliding plate 703.

[0034] During operation, after the waste material is fed from the conical feed port of the feed plate 4, the forward and reverse rotation of the rotating cylinder 605 will drive the cam 701 to rotate. The rotation of the cam 701 will push the slide column 702 to reciprocate through the protrusions on its surface. The reciprocating motion of the slide column 702 will drive the sliding plate 703 to reciprocate on the surface of the feed plate 4. At this time, the reciprocating motion of the sliding plate 703 can pre-disperse the waste material that is fed in clumps, so that the subsequent pusher plate 502 can continue to disperse it. And because the sliding plate 703 is inclined, it can also prevent the waste material from being overly dispersed by the rapid reciprocating motion of the sliding plate 703, which would affect the subsequent movement of the waste material to the position of the extrusion roller 205. At this time, the pusher plate 502 cannot effectively push the waste material. It should be noted that by setting a reset spring on the surface of the slide column 702 and making the slide plate 703 a deformable material, interference between the slide plate 703 and the feed plate 4 can be avoided when the slide plate 703 pushes the waste, which would affect the effect of pushing the waste. This can effectively improve the pre-treatment effect of the waste and facilitate the subsequent extrusion roller 205 to extrude it.

[0035] Reference Figures 8 to 11 The convex disc 701 and multiple elastic levers 606 are staggered on the surface of the rotating cylinder 605. The surface of the convex disc 701 has a groove that matches one end of the sliding column 702. A support plate is slidably connected to the surface of the sliding column 702. Both ends of the support plate are fixedly connected to the feed plate 4.

[0036] During operation, when the rotating cylinder 605 drives the cam 701 and multiple elastic levers 606 to rotate synchronously, the rotation of the elastic levers 606 can move the waste material on the surface of the pusher plate 502, preventing the waste material from being on the surface of the pusher plate 502 and affecting the processing effect of the pusher plate 502 on the waste material. At the same time, the sliding column 702 drives the sliding plate 703 to move, which can reduce the impact of the waste material on the subsequent pusher plate 502, so that the pusher plate 502 can better process the waste material, thereby further improving the squeezing effect of the extrusion roller 205 on the waste material, and thus improving the crushing effect of the crushing roller 3 on the waste material. It should be noted that by sliding the support plate and fixing the feed plate 4 to the sliding column 702, the stability of the reciprocating motion of the sliding column 702 can be effectively improved, and the sliding column 702 can slide quickly inside the support plate, thereby improving the effect of the sliding plate 703 on waste processing.

[0037] Reference Figures 10 to 11 The motor 201 is fixedly connected to the cover plate 9. Two sets of motor 201 and screw 202 are provided above the cover plate 9. The baffle 8 is arranged in an arc shape on the outside of the crushing roller 3, and a ventilation opening is provided on the side near the outer shell 1.

[0038] During operation, by setting two sets of motor 201 and screw 202 above cover plate 9, the stability of the screw 202 driving the moving plate 203 to move and adjust inside cover plate 9 can be effectively improved. Furthermore, by setting baffle 8 in an arc shape on the outside of crushing roller 3, the splashes that may be generated during the crushing of waste by crushing roller 3 will not affect the normal operation of components such as extrusion roller 205. Moreover, by leaving a ventilation opening on the side of baffle 8 near the outer shell 1, the exhaust gas generated by crushing roller 3 during the crushing of waste can be discharged.

[0039] Reference Figures 4 to 6 The telescopic rod 501 is equipped with a return spring at its telescopic position, and the top rod 505 slides in a groove opened inside the telescopic rod 501. A compression spring is provided between the telescopic rod 501 and the mounting plate 204.

[0040] During operation, a return spring is installed at the sliding position of the swing telescopic rod 501. This ensures that after the swing telescopic rod 501 slides to its limit position, it provides a stable pushing force to the pusher plate 502. Since the swing telescopic rod 501 and the mounting plate 204 are rotatably connected by a pin, a strong spring is installed between them. This prevents the swing telescopic rod 501 from being affected by the mounting plate 204 when it is driven by the mounting plate 204, thus providing stability during the angle change process. As a result, the swing telescopic rod 501 can drive the pusher plate 502 to process the waste, thereby improving the waste processing effect and enhancing the subsequent extrusion and crushing of the waste.

[0041] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
