Description

Technical Field

[0001] This invention relates to the field of cardboard waste processing equipment, specifically to a recyclable corrugated cardboard waste processing equipment. Background Technology

[0002] Corrugated cardboard waste processing equipment is a resource-based equipment that recycles waste through processes such as crushing, compaction, baling, or pulping. Among these processes, the crusher is the core equipment in the front-end process, mainly used to shred the cardboard to facilitate subsequent processes.

[0003] In existing technologies, most cardboard shredders typically employ a dual-shaft shearing structure, consisting of a shredding chamber, dual-shaft cutter rollers, and a drive system. During operation, workers first shred waste cardboard boxes into cardboard pieces, then feed the cardboard into the hopper. The rotation of the dual-shaft cutter rollers causes the cardboard to be squeezed and shredded under slow rotation. Finally, the shredded pieces are discharged from the outlet and collected for the next processing step, completing the pre-treatment of the corrugated cardboard boxes.

[0004] However, the positions of the cutter rollers in existing cardboard shredders are usually fixed. Some machines use one set of cutter rollers to shred the cardboard in a single pass, while others, requiring smaller and finer shreds, use two sets of cutter rollers for secondary shredding. But regardless of whether the shredder uses one or two sets of cutter rollers, the final size of the discharged paper pieces cannot be changed. In other words, a single machine can only adapt to one specific shredding precision requirement and cannot switch between coarse and fine shredding based on subsequent processing needs. Therefore, this invention proposes a recyclable corrugated cardboard waste processing device to effectively solve the above-mentioned drawbacks. Summary of the Invention

[0005] The purpose of this invention is to provide a recyclable corrugated cardboard waste processing equipment to solve the problems mentioned in the background art.

[0006] The present invention is achieved through the following technical solution: a recyclable corrugated cardboard waste processing equipment, including a crusher, wherein the crusher includes a machine body, and coarse crushing roller group and fine crushing roller group are installed at intervals from top to bottom in the machine body; The coarse crushing cutter roller assembly includes two first cutter rollers and two first rotating shafts. The two first cutter rollers rotate around the two first rotating shafts respectively to move closer to or further away from each other. The fine crushing cutter roller assembly includes two second cutter rollers and two second rotating shafts. The two second cutter rollers rotate around the two second rotating shafts respectively to move closer to or further away from each other. The four rotating shafts are symmetrically distributed on the machine body. A synchronous transmission mechanism is provided between the first and second rotating shafts on the same side. A clutch mechanism is provided between the synchronous transmission mechanism and the rotating shafts. The clutch mechanism includes a first docking part provided on the synchronous transmission mechanism and a second docking part provided on the rotating shaft. The first docking part and the second docking part can be connected or separated, so that the synchronous transmission mechanism and the rotating shaft can be connected or separated. When the first docking part and the second docking part are connected, the movement of the two second cutter rollers moving closer or further away from each other can be driven by the synchronous transmission mechanism to move the two first cutter rollers further away or closer to each other; when the first docking part and the second docking part are separated, the coarse crushing cutter roller group and the fine crushing cutter roller group can open and close independently.

[0007] Optionally, the synchronous transmission mechanism includes two synchronous pulleys that are coaxially corresponding to the first rotating shaft and the second rotating shaft, respectively. A synchronous belt meshes with both synchronous pulleys. The first mating part is disposed at the end of the wheel axle of the synchronous pulley, and the second mating part is disposed at the end of the rotating shaft.

[0008] Optionally, the first docking part includes a first coupling that is coaxially rotatably fitted onto the end of the axle of the synchronous pulley. The first coupling has a cover structure with an open end facing the synchronous pulley. An annular cavity is formed between the inner wall of the first coupling and the outer wall of the axle. Two symmetrically distributed limiting plates protrude from the inner wall of the first coupling toward the annular cavity. Two symmetrically distributed limiting protrusions protrude from the outer wall of the axle of the synchronous pulley toward the annular cavity. The two limiting plates and the two limiting protrusions are arranged circumferentially in the annular cavity. Four circumferentially arranged compression springs are installed in the annular cavity. The two ends of the compression springs abut against the limiting plates and the limiting protrusions, respectively. In the natural state, the compression springs are in a compressed state.

[0009] Optionally, the second mating part includes a second pair of connectors coaxially fixedly mounted on the end of the rotating shaft. The second pair of connectors and the first pair of connectors are arranged facing each other, and the facing surfaces of the first pair of connectors and the second pair of connectors have teeth that can mesh with each other. When the teeth of the facing surfaces of the first pair of connectors and the second pair of connectors mesh, the second cutter roller can drive the first cutter roller to swing synchronously through a synchronous transmission mechanism.

[0010] Optionally, the crusher further includes a linear drive mechanism, the drive end of which is disposed on the synchronous transmission mechanism. The linear drive mechanism can control the synchronous transmission mechanism to move closer to or away from the machine body in the horizontal direction, so that the first pair of joints and the second pair of joints can engage or disengage.

[0011] Optionally, the first cutter roller and the first rotating shaft are connected by a first guide plate, one side of the first guide plate is fixedly connected to the first rotating shaft, and the side of the first guide plate away from the first rotating shaft is rotatably connected to the roller shaft of the first cutter roller. The second cutter roller and the second rotating shaft are connected by a second guide plate. One side of the second guide plate is fixedly connected to the second rotating shaft, and the side of the second guide plate away from the second rotating shaft is rotatably connected to the roller shaft of the second cutter roller.

[0012] Optionally, the end of the rotating shaft away from the synchronous transmission mechanism extends out of the outer side of the machine body and is fixedly connected to a drive handle. A bolt is threaded onto the drive handle, and a threaded hole is opened on the side of the guide plate opposite the bolt. Several positioning holes are opened on the side wall of the machine body. When the drive handle controls the guide plate to rotate around the corresponding rotating shaft, the threaded hole can be aligned with one of the positioning holes for the bolt to be inserted to fix the drive handle and the guide plate.

[0013] Optionally, the crusher further includes a cutter roller drive system, which includes at least three sets of cutter roller drive mechanisms, wherein one set of cutter roller drive mechanisms is set to correspond to the meshing fine crushing cutter roller group and is used to drive two second cutter rollers to rotate in opposite directions; The other two sets of cutter roller drive mechanisms are set up to correspond to the coarse crushing cutter roller group in the meshing state, and are used to drive the two first cutter rollers to rotate in opposite directions. The meshing depth of the coarse crushing cutter roller group corresponding to one set of cutter roller drive mechanisms is greater than the meshing depth of the coarse crushing cutter roller group corresponding to the other set of cutter roller drive mechanisms.

[0014] Optionally, the cutter roller drive mechanism includes two gears that mesh and rotate on the side wall of the machine body. The two gears are coaxially arranged corresponding to two cutter roller shafts in the same cutter roller group. A connecting mechanism is provided between the shaft of the gear and the cutter roller shaft. The connecting mechanism is used to connect or separate the shaft of the gear and the cutter roller shaft.

[0015] Optionally, the cutter roller shaft has an internal hollow structure. The connecting mechanism includes a connecting rod that is slidably disposed within the inner cavity of the cutter roller shaft along its axial direction. The connecting rod has a polygonal end face. The shaft end of the gear has a groove that matches the shape of the connecting rod and allows the end of the connecting rod to be embedded in the groove. The connecting mechanism also includes an electromagnet fixedly disposed within the inner cavity of the cutter roller shaft. A return spring is installed within the inner cavity of the cutter roller shaft along its own axial direction. The two ends of the return spring abut against the connecting rod and the electromagnet, respectively. When the electromagnet is energized, the magnetic attraction force generated by the electromagnet on the connecting rod is greater than the elastic force exerted by the return spring on the connecting rod. In its natural state, the return spring is in a compressed state.

[0016] Compared with the prior art, the present invention provides a recyclable corrugated cardboard box waste processing equipment, which has the following beneficial effects: 1. This invention sets up coarse crushing roller groups and fine crushing roller groups inside the machine body, and connects the rollers and the rotating shaft with guide plates, allowing the rollers to rotate around the rotating shaft. This enables the two rollers in the coarse crushing roller group and the two rollers in the fine crushing roller group to move closer or further apart from each other. This allows the equipment to have three working modes: single coarse crushing mode, single fine crushing mode, and a combination of coarse and fine crushing mode. Users can select different modes to process corrugated cardboard waste according to subsequent processing needs, thus improving the applicability of the equipment to different working requirements. 2. This invention uses a clutch mechanism to connect or separate the synchronous transmission mechanism and the cutter roller assembly. This allows the user to not only control each cutter roller to swing independently to achieve the opening and closing of different cutter rollers, but also to control the two first cutter rollers to move closer together by moving the two second cutter rollers away from each other. This results in a greater meshing depth between the two first cutter rollers, thereby increasing the compression depth of the first cutter rollers on the paperboard. This allows the first cutter rollers to better shred the paperboard, reducing the occurrence of paper strips sticking together and not being completely cut, and improving the crushing accuracy of the paperboard.

[0019] 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, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 10 This application proposes a recyclable corrugated cardboard waste processing equipment, including a crusher. The crusher includes a body 1, and coarse crushing roller group 2 and fine crushing roller group 3 are installed at intervals from top to bottom inside the body 1. The coarse crushing roller group 2 includes two first cutter rollers 201 and two first rotating shafts 202. The two first cutter rollers 201 rotate around the two first rotating shafts 202 respectively to move closer to or further away from each other. The fine crushing roller group 3 includes two second cutter rollers 301 and two second rotating shafts 302. The two second cutter rollers 301 rotate around the two second rotating shafts 302 respectively to move closer to or further away from each other.

[0021] The machine body 1 includes a hopper with an open top and bottom. The coarse crushing roller group 2 and the fine crushing roller group 3 are installed inside the hopper. After being crushed by the coarse crushing roller group 2 and the fine crushing roller group 3, the corrugated cardboard waste is discharged from the open bottom. A collection bin can be set at the bottom, or it can be directly connected to the conveying mechanism of the next process to transport the crushed waste to the next process for processing.

[0022] On the other hand, the spacing between the blades on the second cutter roller 301 is smaller than the spacing between the blades on the first cutter roller 201, meaning the blades on the second cutter roller 301 are denser and narrower, enabling finer crushing of the cardboard. When the two first cutter rollers 201 are close to each other in an meshing state and the two second cutter rollers 301 are far apart, the equipment is in coarse crushing mode; when the two second cutter rollers 301 are close to each other in an meshing state and the two first cutter rollers 201 are far apart, the equipment is in fine crushing mode; when the two first cutter rollers 201 are close to each other in an meshing state and the two second cutter rollers 301 are close to each other in an meshing state, the equipment is in a combination of coarse and fine crushing mode.

[0023] Workers can select different working modes according to the crushing needs. For example, when crushing corrugated cardboard with more than three layers and where the crushing precision requirement is not high, the coarse crushing roller group 2 can be used alone for coarse crushing. When crushing corrugated cardboard with more than three layers and where smaller pieces of paper are required, the coarse crushing roller group 2 and the fine crushing roller group 3 can be used in combination. The stronger coarse crushing roller group 2 is used first to coarsely crush the cardboard, avoiding the phenomenon of the cutter disc breaking when the fine crushing roller group 3 is used directly to crush thick cardboard. When crushing corrugated cardboard with less than three layers and where smaller pieces of paper are required, the fine crushing roller group 3 can be used alone. Thin cardboard will not damage the cutter disc of the fine crushing roller group 3, and the fine crushing roller group 3 can crush the cardboard independently.

[0024] Furthermore, the first cutter roller 201 and the first rotating shaft 202 are connected by a first guide plate 203. One side of the first guide plate 203 is fixedly connected to the first rotating shaft 202, and the side of the first guide plate 203 away from the first rotating shaft 202 is rotatably connected to the roller shaft of the first cutter roller 201. Therefore, by rotating the first rotating shaft 202, the first guide plate 203 can be controlled to swing, thereby driving the first cutter roller 201 to swing around the first rotating shaft 202. The cutter roller shaft of the first cutter roller 201 and the first guide plate 203 are rotatably connected by a damping bearing, and the first rotating shaft 202 and the side wall of the machine body 1 are rotatably connected by a damping bearing, improving the stability of the rotation of the first rotating shaft 202 and the operation of the first cutter roller 201.

[0025] The second cutter roller 301 and the second rotating shaft 302 are connected by a second guide plate 303. One side of the second guide plate 303 is fixedly connected to the second rotating shaft 302, and the side of the second guide plate 303 away from the second rotating shaft 302 is rotatably connected to the roller shaft of the second cutter roller 301. Therefore, by rotating the second rotating shaft 302, the swing of the second guide plate 303 can be controlled, thereby driving the second cutter roller 301 to swing around the second rotating shaft 302. The cutter roller shaft of the second cutter roller 301 and the second guide plate 303 are rotatably connected by a damping bearing, and the second rotating shaft 302 and the side wall of the machine body 1 are rotatably connected by a damping bearing, improving the stability of the rotation of the second rotating shaft 302 and the operation of the second cutter roller 301.

[0026] like Figure 3 As shown, funnel-shaped cover plates are symmetrically arranged at the top opening of the machine body 1. Two first guide plates 203 are distributed in a figure-eight shape, and two second guide plates 303 are distributed in a V-shape. The cover plates and second guide plates 303 both play a certain guiding role for the cardboard waste, so that the cardboard can reach between the two first cutter rollers 201 and the two second cutter rollers 301. In actual application, a sealing plate is rotatably connected to the edge of the cover plate at the top of the machine body 1 to seal the gap between the first cutter rollers 201 and the cover plate, so as to prevent the cardboard from falling to the outside of the two first cutter rollers 201. When the first cutter rollers 201 rotate around the first rotating shaft 202, the sealing plate can flip over and will not hinder the swing process of the first cutter rollers 201.

[0027] In this embodiment, four rotating shafts are symmetrically distributed on the machine body 1. A synchronous transmission mechanism 4 is provided between the first rotating shaft 202 and the second rotating shaft 302 on the same side. A clutch mechanism 5 is provided between the synchronous transmission mechanism 4 and the rotating shafts. The clutch mechanism 5 includes a first docking part provided on the synchronous transmission mechanism 4 and a second docking part provided on the rotating shafts. The first docking part and the second docking part can be connected or separated, so that the synchronous transmission mechanism 4 and the rotating shafts can be connected or separated. When the first docking part and the second docking part are connected, the movement of the two second cutter rollers 301 moving closer or further away from each other can be driven by the synchronous transmission mechanism 4 to drive the two first cutter rollers 201 to move further away or closer to each other. When the first docking part and the second docking part are separated, the coarse crushing cutter roller group 2 and the fine crushing cutter roller group 3 can open and close independently.

[0028] Specifically, the synchronous transmission mechanism 4 includes two synchronous pulleys 401 coaxially corresponding to the first rotating shaft 202 and the second rotating shaft 302, respectively. A synchronous belt 402 meshes with both synchronous pulleys 401. A first mating part is located at the end of the pulley axle of the synchronous pulley 401, and a second mating part is located at the end of the rotating shaft. Therefore, when the two synchronous pulleys 401 are connected to the first rotating shaft 202 and the second rotating shaft 302 respectively, the rotation of the second rotating shaft 302 can drive the first rotating shaft 202 to rotate synchronously through the synchronous transmission mechanism 4. When the two second cutter rollers 301 move away from each other, they can drive the two first cutter rollers 201 to move closer together, thereby increasing the meshing depth of the two first cutter rollers 201. This allows the first cutter rollers 201 to squeeze the thick cardboard more deeply, reducing the occurrence of uncut cardboard sticking together after breakage.

[0029] The mutual approach or distance of the first cutter rollers 201 can be controlled individually, or can be controlled in conjunction with the mutual approach or distance of the second cutter rollers 301. When it is necessary to temporarily adjust the coarse crushing gap, or when only one side of the cutter rollers needs to work, or when the synchronous transmission mechanism 4 needs to be maintained, the individual control mode can be used. When processing regular thick corrugated boxes daily, and it is necessary to switch between coarse crushing mode and fine crushing mode repeatedly, the synchronous transmission mechanism 4 can simplify the mode switching and greatly improve production efficiency.

[0030] Furthermore, the first docking part includes a first mating joint 501 coaxially rotatably mounted on the axle end of the synchronous pulley 401. The first mating joint 501 has a cover structure, with one end facing the synchronous pulley 401 being open. An annular cavity is formed between the inner wall of the first mating joint 501 and the outer wall of the axle. Two symmetrically distributed limiting plates 502 protrude from the inner wall of the first mating joint 501 toward the annular cavity. Two symmetrically distributed limiting protrusions 403 protrude from the outer wall of the axle of the synchronous pulley 401 toward the annular cavity. The two limiting plates 502 and the two limiting protrusions 403 are arranged circumferentially in the annular cavity. Four circumferentially arranged compression springs 503 are installed in the annular cavity. The two ends of the compression springs 503 abut against the limiting plates 502 and the limiting protrusions 403, respectively. In the natural state, the compression springs 503 are in a compressed state.

[0031] The limiting plate 502 is fixedly connected to the inner wall of the first coupling 501, and the limiting protrusion 403 is fixedly connected to the outer wall of the axle of the synchronous wheel 401. The first coupling 501 can rotate a certain angle on the outer side of the axle. In this embodiment, the rotation angle does not exceed 120°. An annular sealing plate is fixedly and detachably connected to the edge of the opening end of the first coupling 501 to limit the compression spring 503 and prevent the compression spring 503 from leaving the annular cavity. The annular sealing plate and the end face of the limiting protrusion 403 abut against each other to improve the stability of the first coupling 501 when rotating. The compression spring 503 has a large elastic coefficient, which enables the first coupling 501 to remain stable and not rotate when not disturbed by external forces.

[0032] Furthermore, the second docking part includes a second mating joint 504 coaxially fixedly mounted on the end of the rotating shaft. The second mating joint 504 and the first mating joint 501 are arranged facing each other. The facing surfaces of the first mating joint 501 and the second mating joint 504 have teeth 505 that can mesh with each other. When the teeth 505 of the facing surfaces of the first mating joint 501 and the second mating joint 504 mesh, the second cutter roller 301 can drive the first cutter roller 201 to swing synchronously through the synchronous transmission mechanism 4. The toothed insert 505 has a beveled sidewall on one side and a vertical plane on the other, with a narrow tapered tip less than 1mm wide. This allows the toothed insert 505 on the second pair of connectors 504 to abut against the toothed insert 505 on the first pair of connectors 501 as the first pair of connectors 501 approaches the second pair of connectors 504. This drives the first pair of connectors 501 to rotate a certain angle until the two toothed inserts 505 are fully engaged. At this point, the rotation of the synchronous pulley 401 causes the axle to... Through the cooperation of the limiting protrusion 403, the compression spring 503, and the limiting plate 502, the elastic coefficient of the compression spring 503 can provide a stable driving force for the rotation of the first pair of joints 501 and the second pair of joints 504. Through the synchronous transmission mechanism 4, the first pair of joints 501 is driven to rotate synchronously, thereby causing the second pair of joints 504 to rotate, which in turn causes the second rotating shaft 302 and the first rotating shaft 202 to rotate synchronously, realizing the operation of driving the two second cutter rollers 301 to move closer or further away from each other and driving the two first cutter rollers 201 to move further or further away from each other.

[0033] It should be noted that the crusher also includes a linear drive mechanism. The drive end of the linear drive mechanism is set on the synchronous transmission mechanism 4. The linear drive mechanism can control the synchronous transmission mechanism 4 to move closer to or away from the machine body 1 in the horizontal direction, so that the first pair of joints 501 and the second pair of joints 504 engage or disengage. The crusher also includes a workbench for supporting various components. Several mounting brackets are fixed on the workbench. The linear drive mechanism is mounted on one of the mounting brackets. The linear drive mechanism can be a cylinder, a linear slide, or other mechanism, and can be selected according to actual needs.

[0034] On the other hand, the two synchronous pulleys 401 in the synchronous transmission mechanism 4 are connected to a connecting plate on their axles. The axles are rotatably connected to the connecting plate through damping bearings. The drive end of the linear drive mechanism is fixedly connected to the connecting plate to control the synchronous transmission mechanism 4 to move in the horizontal direction.

[0035] Furthermore, the end of the rotating shaft away from the synchronous transmission mechanism 4 extends out of the outer side of the machine body 1 and is fixedly connected to a drive handle 6. The operator can control the rotation of the rotating shaft through the drive handle 6, thereby controlling the first cutter roller 201 or the second cutter roller 301 to swing around the rotating shaft. A bolt 601 is threadedly connected to the drive handle 6, and a threaded hole is opened on the side of the guide plate opposite to the bolt 601. Several positioning holes 101 are opened on the side wall of the machine body 1. When the drive handle 6 controls the guide plate to rotate around the corresponding rotating shaft, the threaded hole can be aligned with one of the positioning holes 101, allowing the bolt 601 to be inserted to fix the drive handle 6 and the guide plate.

[0036] In this embodiment, three positioning holes 101 are provided in the area corresponding to each drive handle 6. The three positioning holes 101 are distributed around the circumference of the corresponding rotating shaft, and the three positioning holes 101 correspond to the open state, shallow engagement state and deep engagement state of the cutter roller, respectively. Therefore, the equipment can be adjusted to the corresponding working mode simply by aligning the bolt 601 with the corresponding positioning hole 101 during adjustment, which is convenient and quick to operate.

[0037] It should be noted that the crusher also includes a cutter roller drive system, which includes at least three sets of cutter roller drive mechanisms 7. One set of cutter roller drive mechanisms 7 is configured to drive the two second cutter rollers 301 to rotate in opposite directions in the meshing state of the fine crushing cutter roller group 3. The other two sets of cutter roller drive mechanisms 7 are configured to drive the two first cutter rollers 201 to rotate in opposite directions in the meshing state of the coarse crushing cutter roller group 2, and the meshing depth of the coarse crushing cutter roller group 2 corresponding to one set of cutter roller drive mechanisms 7 is greater than the meshing depth of the coarse crushing cutter roller group 2 corresponding to the other set of cutter roller drive mechanisms 7. When the coarse crushing cutter roller group 2 is used alone, and the meshing depth of the cutter rollers in the coarse crushing cutter roller group 2 is increased by the fine crushing cutter roller group 3, the coarse crushing cutter roller group 2 will engage with one of the sets of cutter roller drive mechanisms 7, thereby enabling the cutter rollers in the coarse crushing cutter roller group 2 to rotate normally.

[0038] Specifically, the cutter roller drive mechanism 7 includes two meshing and rotatably mounted gears 701 on the side wall of the machine body 1. The two gears 701 are coaxially mounted corresponding to two cutter roller shafts in the same cutter roller group. A connecting mechanism 8 is provided between the shaft of the gear 701 and the cutter roller shaft. The connecting mechanism 8 is used to connect or separate the shaft of the gear 701 and the cutter roller shaft.

[0039] The cutter roller drive mechanism 7 also includes a motor and a reducer fixedly mounted on the mounting bracket. The output shaft of the reducer and the shaft of one of the gears 701 are coaxially fixedly connected, and the shaft of the gear 701 and the side wall of the machine body 1 are rotatably connected through a damping bearing. The motor and the reducer drive the gear 701 to rotate slowly and steadily, thereby driving the first cutter roller 201 or the second cutter roller 301 to rotate slowly and steadily.

[0040] On the other hand, the shaft of gear 701 extends into the machine body 1 and can be aligned with the cutter roller shaft, while the connecting mechanism 8 is provided on the cutter roller shaft to connect or separate from the shaft of gear 701.

[0041] Specifically, such as Figure 7 As shown, the cutter roller shaft has an internally hollow structure. The connecting mechanism 8 includes a connecting rod 801 that is slidably disposed within the inner cavity of the cutter roller shaft along its axial direction. The end face of the connecting rod 801 has a polygonal structure. The space inside the cutter roller shaft for the connecting rod 801 to slide is adapted to the shape of the connecting rod 801, so that the connecting rod 801 can only move along the axial direction of the cutter roller shaft and cannot rotate. Furthermore, the shaft end of the gear 701 has a groove that is adapted to the shape of the connecting rod 801 and allows the end of the connecting rod 801 to be inserted into the groove. Therefore, when the end of the connecting rod 801 is inserted into the groove, the rotation of the gear 701 shaft can drive the cutter roller shaft to rotate through the connecting rod 801, thereby causing the cutter roller to rotate.

[0042] Furthermore, the connecting mechanism 8 also includes an electromagnet 802 fixedly disposed within the inner cavity of the cutter roller shaft. A return spring 803 is mounted axially within the inner cavity of the cutter roller shaft, with its two ends abutting against the connecting rod 801 and the electromagnet 802, respectively. When the electromagnet 802 is energized, the magnetic attraction force generated by the electromagnet 802 on the connecting rod 801 is greater than the elastic force exerted by the return spring 803 on the connecting rod 801. In its natural state, the return spring 803 is in a compressed state. An iron sheet is fixedly connected to one end of the connecting rod 801 within the inner cavity of the cutter roller shaft. The electromagnet 802 is detachably and fixedly installed within the inner cavity via a flange bracket inside the cutter roller shaft. In this design, the end of the cutter roller shaft has a detachable annular cover plate, allowing the structure within the inner cavity of the cutter roller shaft to be exposed by removing the cover plate, facilitating maintenance and replacement.

[0043] On the other hand, a power supply connected to the electromagnet 802 is provided in the inner cavity of the cutter roller shaft. A signal circuit switch is provided between the power supply and the electromagnet 802. The current is controlled by the signal sent by the external control system, so that the connecting rod 801 can be magnetically attracted by the electromagnet 802 or popped out by the return spring 803.

[0044] The working principle and usage process of this invention are as follows: In the coarse crushing mode, the two second cutter rollers 301 are controlled to move away from each other, while the two first cutter rollers 201 are controlled to move closer to each other until they are meshed. The cutter roller shaft of the first cutter roller 201 is connected to one of the cutter roller drive mechanisms 7 through the connecting mechanism 8, so that the cutter roller drive mechanism 7 controls the two first cutter rollers 201 to rotate towards each other to crush the cardboard. When the thickness of the cardboard increases again, the two first cutter rollers 201 can be controlled to move closer to each other until they are deeply meshed. At this time, the first cutter roller 201 is driven to continue to rotate through the other cutter roller drive mechanism 7, so that the first cutter roller 201 can crush the thick cardboard.

[0045] When using the fine shredding mode, control the two second cutter rollers 301 to move closer to each other until they are engaged, and control the two first cutter rollers 201 to move further apart. The second cutter rollers 301 are controlled to rotate by one of the cutter roller drive mechanisms 7 to achieve the operation of shredding the cardboard.

[0046] When the combined mode is required, the two first cutter rollers 201 are controlled to approach each other to mesh, and the two second cutter rollers 301 are also controlled to approach each other to mesh. This allows the cardboard to undergo coarse crushing by the first cutter rollers 201 and then fine crushing by the second cutter rollers 301, thereby improving the crushing accuracy of the cardboard and meeting the subsequent processing requirements.
