Description

Technical Field

[0001] This application belongs to the field of non-metallic waste processing technology, specifically relating to a system and method for recycling and processing waste edges of sheet metal. Background Technology

[0002] Polycarbonate (PC) sheets are plastic sheets made primarily from polycarbonate. They are lightweight, impact-resistant, heat-insulating, and UV-resistant, and are widely used in building skylights, greenhouses, and advertising light boxes. During the production process, uneven thickness, burrs, or warping may occur at the edges of these sheets, failing to meet production standards. These defects are commonly referred to as "waste edges."

[0003] In existing technologies, production units typically cut off the waste edges on both sides during the sheet material conveying process, and then recycle and crush the waste edges to regranulate and reuse them. However, the recycled granules generated by regranulation can usually only be used for low-requirement products (or non-transparent products). This is because after one round of processing, the material properties and transparency of polycarbonate have decreased, and impurities such as dust and cutting debris are easily mixed in during the cutting, recycling, and crushing processes, causing color problems in the material.

[0004] As market demands become increasingly sophisticated, many users, driven by cost considerations, are showing a growing acceptance of products with lower requirements, and these acceptance standards are becoming more tiered. Against this backdrop, optimizing waste edge recycling processes to consistently produce high-quality recycled pellets has become a critical issue that urgently needs to be addressed. Summary of the Invention

[0005] This application provides a system and method for recycling waste edges of sheet metal, which aims to reduce the amount of dust and cutting debris adhering to the waste edges, thereby mitigating the impact of such impurities on the waste edges and ensuring the stability of high-quality recycled pellet production.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A system for recycling and processing waste edges of sheet metal is provided, comprising:

[0008] Two sets of vertical cutting components are used to be installed behind the injection molding equipment and the molding die, and are respectively installed on both sides of the width direction of the sheet material; the vertical cutting components are used to cut along the length direction of the sheet material at the junction of the waste edge and the sheet material, so that the waste edge is transformed into an edge body that maintains a connection with the sheet material;

[0009] A suction assembly is used to collect cutting debris generated by the vertical cutting assembly acting on the plate, as well as surrounding dust; and

[0010] Two sets of storage components are respectively set behind the two sets of vertical cutting components to allow the edge body to enter; each set of storage components is provided with a horizontal cutting component, which is used to cut along a direction perpendicular to the length of the board to separate the edge body from the board, and the separated edge body is located inside the storage component.

[0011] In one possible implementation, the storage component includes:

[0012] A support bracket is used to be mounted on one side of the sheet metal along its width; a rotating roller is rotatably mounted on the support bracket, the axis of the roller being parallel to the translational direction of the sheet metal, and a first rotating motor is connected to the support bracket for transmission; and

[0013] Multiple positioning parts are arranged at intervals around the outer periphery of the rotating roller, and each positioning part is connected to the rotating roller;

[0014] Each of the positioning parts is detachably provided with an insert; the rotating roller can rotate so that any one of the inserts is coaxially arranged with the edge body and the insert faces the edge body, so that the edge body can be inserted.

[0015] In one possible implementation, the positioning part has a strip groove on the side facing away from the rotating roller, and the strip groove passes through one end of the positioning part along the axial direction of the rotating roller;

[0016] The insert is adapted to be slidably inserted into the strip groove along the axial direction of the roller, and partially extends to the outside of the positioning part so as to be coaxially arranged with the edge body.

[0017] In one possible implementation, the cross-cutting assembly includes a plurality of cross-cutting blades respectively disposed on a plurality of positioning portions, each of the cross-cutting blades being slidably connected to the end face through which the strip groove passes, and the end face of the cross-cutting blade facing away from the rotating roller being its cutting edge.

[0018] The positioning part is provided with a first linear cylinder, and the power output axis of the first linear cylinder is perpendicular to the sliding direction of the cross-cutting blade.

[0019] The power output end of the first linear cylinder is hinged to a transmission arm, and the swing end of the transmission arm is hinged to the cross-cutting blade.

[0020] When the first linear cylinder is activated, the transmission arm swings and the cross-cutting blade moves toward or away from the rotating roller.

[0021] In one possible implementation, the suction component includes:

[0022] Suspension, used to mount above the sheet metal;

[0023] Two sealing boxes are both located on the underside of the suspension; each sealing box has a downwardly extending air intake pipe for facing the two edge bodies respectively; and

[0024] An air extraction component is connected to the two sealed boxes to extract the gas inside the sealed boxes, thereby creating a negative pressure state inside the sealed boxes.

[0025] The intake pipe has a first isolation mesh for intercepting coarse particles in the impurities, and the sealed box has a second isolation mesh for intercepting fine particles in the impurities.

[0026] In one possible implementation, the intake pipe is provided with a baffle extending along its axial direction to divide the interior of the intake pipe into a first chamber and a second chamber; the first chamber is used for airflow, and the lower end of the intake pipe is connected to a storage cover for sealing the second chamber;

[0027] The first isolation net includes:

[0028] A rotating frame is rotatably mounted on the upper surface of the partition plate and is connected to a second rotating motor; and

[0029] Multiple screen plates are arranged inside the rotating frame and spaced apart along the circumference of the rotating frame;

[0030] When the rotating frame rotates, any one of the screen plates is adapted to move to the inside of the second chamber so that the impurities attached to the screen plate fall into the second chamber;

[0031] Each of the screen plates has a degree of freedom to move along the axial direction of the rotating frame; a pushing assembly is provided in the second chamber, which is used to push the screen plate upward so that the screen plate moves upward; and each of the screen plates is connected to the rotating frame through an elastic reset member, which is used to drive the screen plate to move downward.

[0032] In one possible implementation, a reserved slot is provided on the upper surface of the partition, the second rotating motor is disposed in the reserved slot and connected to the rotating frame through a drive shaft;

[0033] The pushing assembly includes:

[0034] Two rotating arms are both disposed within the second chamber and are rotatably connected to the partition plate; and

[0035] The lifting arm has its two ends connected to the swing ends of the two rotating arms, respectively;

[0036] One of the rotating arms has a connecting rod coaxially arranged with its rotation axis, the connecting rod passing through the partition and extending into the reserved groove;

[0037] The extended end of the connecting rod is coaxially connected to a driven helical gear, and the drive shaft is coaxially connected to a driving helical gear that meshes with the driven helical gear.

[0038] In one possible implementation, the vertical cutting component includes:

[0039] A base; the upper side of the base has an adjustment seat that is rotatably connected to it in the vertical direction, and the adjustment seat and the base have a locking structure; a mounting plate is slidably arranged on the adjustment seat in the horizontal direction, and the mounting plate is driven by a linear drive component.

[0040] A vertical cutting blade, disposed at one end of the mounting plate, has a cutting surface oriented toward the translational direction of the plate; and

[0041] The vertical cutting saw disc is rotatably mounted at the other end of the mounting plate and is connected to a third rotating motor.

[0042] In one possible implementation, the vertical cutting blade is connected to the mounting plate via a hinge, so that the vertical cutting blade can swing about the central axis of the hinge to a horizontal or vertical state.

[0043] When the vertical cutting blade is in the vertical state, the cutting edge of the vertical cutting blade faces the direction of translation of the plate.

[0044] A blade housing is slidably disposed on the mounting plate; when the vertical cutting blade is in the horizontal state, the blade housing is adapted to move to fit around the outer periphery of the vertical cutting blade.

[0045] In this embodiment, two sets of vertical cutting components are used to vertically cut the waste edges on both sides, creating a gap between the waste edges and the board while maintaining a connection, forming edge bodies located on both sides of the board's width direction. During the vertical cutting process, the suction component can collect cutting debris and surrounding dust generated at the processing location, ensuring that the surface of the edge body is clean. Subsequently, the edge body moves synchronously with the translation of the board until it enters the storage component on the same side. On this basis, the transverse cutting component on the storage component can transversely cut the edge body, separating it from subsequent edge bodies, i.e., separating it from the board. Since the separated edge body is inside the storage component, the surface of this part of the edge body is still free of impurities that would interfere with its subsequent processing.

[0046] The waste edge recycling system for boards provided in this embodiment, compared with the prior art, can collect impurities through a suction component and isolate them through a collection component to prevent impurities from being recycled along with the waste edges, thereby avoiding the adverse effects of impurities on the preparation of recycled granules and improving the yield of high-quality recycled granules.

[0047] The technical solution adopted in this application also provides a method for recycling and processing waste edges of sheet metal, based on the waste edge recycling and processing system proposed in any of the foregoing claims, including the following steps:

[0048] A. Before starting the injection molding equipment, turn on the suction assembly to reduce dust in the environment;

[0049] B. Start the injection molding equipment and extrude the sheet backward; at the same time, turn on the two sets of vertical cutting components so that the waste edges on both sides of the sheet are transformed into edge bodies;

[0050] C. Adjust the storage components so that the two sets of edge bodies move synchronously with the board to enter the two sets of storage components respectively;

[0051] D. Open the cross-cutting component to separate the edge body located within the storage component from the board material, and the separated edge body is located inside the storage component;

[0052] E. Repeat steps C and D.

[0053] The beneficial effects of the waste edge recycling method for board provided in this embodiment are as follows: the pretreatment by the suction component can reduce the total amount of dust in the environment. On the one hand, it can avoid dust from interfering with the recycling of waste edges, and on the other hand, it can reduce the amount of dust adhering to the surface of the board.

[0054] In addition, the suction component plays a role in recycling cutting debris during the process of converting waste edges into edge bodies, thereby reducing the amount of impurities adhering to the surface of the waste edges and ensuring that the raw material level of high-quality recycled particles is maintained after the waste edges are converted into edge bodies.

[0055] After the edge body is generated, it can enter the storage component as the board moves to isolate it from the outside world and prevent external impurities from affecting its surface. At the same time, the edge body can be detached after being processed by the cross-cutting component, completing the recycling step. In addition, the cutting debris formed by the cross-cutting component in processing the edge body will be isolated on the outside of the storage component, ensuring the cleanliness of the edge body surface inside the storage component.

[0056] During the continuous recycling of edge bodies, when two adjacent edge body sections separate, their roots interact to cause surface debris to eject in an irregular trajectory, preventing it from completely adhering to the edge body surface and affecting subsequent recycling steps. Based on this, since there is a time interval between the recycling of two adjacent edge body sections (this interval is positively correlated with the maximum length of edge body that the storage component can store), the amount of cutting debris on each edge body section is limited and usually does not adversely affect subsequent processes.

[0057] Compared with existing technologies, this method can effectively reduce the amount of impurities attached to recycled waste edges, improve the recycling quality of board waste edges, and increase the yield of high-quality recycled granules. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0083] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0084] Please refer to the following: Figures 1 to 20 The waste edge recycling system for sheet metal provided in this application will now be described. The waste edge recycling system for sheet metal proposed in this application includes two sets of vertical cutting components 1, a suction component 2, and two sets of storage components 3.

[0085] Two sets of vertical cutting components 1 are used to be installed behind the injection molding equipment and the molding die to act on the injection-molded sheet material; and the two sets of vertical cutting components 1 are respectively installed on both sides of the sheet material width direction to act on the waste edges on both sides of the sheet material.

[0086] In practical use, the vertical cutting component 1 is used to cut along the length of the board at the junction of the waste edge and the board, so that the waste edge is transformed into an edge body that maintains a connection with the board, and there is a certain gap between the edge body and the cut surface of the board.

[0087] The suction component 2 is located on the outside of the board and is used to collect the cutting debris formed by the vertical cutting component 1 acting on the board, as well as the surrounding dust.

[0088] Two sets of storage components 3 are respectively set behind the two sets of vertical cutting components 1 so that edge bodies on the same side can enter; it should be noted that the edge bodies entering the storage components 3 are sealed to isolate external impurities.

[0089] In this embodiment, each storage component 3 is provided with a cross-cutting component, which is used to cut along a direction perpendicular to the length of the board, so that the edge body is separated from the board, and the separated edge body is inside the storage component 3.

[0090] In this embodiment, two sets of vertical cutting components 1 are used to vertically cut the waste edges on both sides, so that a gap appears between the waste edges and the board while maintaining a connection, forming edge bodies located on both sides of the board width direction; during the vertical cutting process, the suction component 2 can collect the cutting debris generated at the processing position, as well as the surrounding dust, to ensure that the surface of the edge body is clean.

[0091] Subsequently, the edge body moves synchronously with the translation of the board until it enters the storage component 3 on the same side. On this basis, the edge body can be transversely cut by the transverse cutting component on the storage component 3 so that the edge body is separated from the subsequent edge body, that is, separated from the board. Since the separated edge body is inside the storage component 3, the surface of this part of the edge body is still free of impurities that would interfere with its subsequent processing.

[0092] The waste edge recycling system for boards provided in this embodiment, compared with the prior art, can collect impurities through the suction component 2 and isolate the impurities through the collection component 3, so as to avoid the impurities being recycled along with the waste edges, thereby avoiding the adverse effects of impurities on the preparation of recycled particles and improving the yield of high-quality recycled particles.

[0093] In some embodiments, such as Figure 1 , Figure 19 and Figure 20 As shown, the storage component 3 includes a bracket 31 and multiple positioning parts 32.

[0094] A support 31 is used to be installed on one side of the sheet metal in the width direction. In this embodiment, the support 31 includes a flat plate portion for contacting the ground and two vertical plates spaced apart along the length direction of the sheet metal to form a U-shaped frame. A rotating roller 311 is rotatably mounted on the support 31. The axial direction of the roller 311 is parallel to the translational direction (i.e., the length direction) of the sheet metal, and both ends of the roller 311 are rotatably connected to the two vertical plates. Furthermore, the roller 311 is driven by a first rotating motor 312 for rotating it. The base of the first rotating motor 312 is fixed to the outside of one of the vertical plates, and the power output end is coaxially connected to the end of the roller 311.

[0095] Multiple positioning portions 32 are spaced around the outer periphery of the rotating roller 311, and each positioning portion 32 is connected to the rotating roller 311. Specifically, the positioning portions 32 are connected to the rotating roller 311 via connecting pieces extending toward the rotating roller 311; and there are reinforcing ribs between adjacent connecting pieces. As the rotating roller 311 rotates, each positioning portion 32 can be aligned with the edge body on the same side, even if the positioning portion 32 is close to the edge body, and the length direction of the positioning portion 32 is parallel to the translational direction of the edge body.

[0096] Each positioning part 32 is detachably provided with a plug 322; as the positioning part 32 approaches the edge body, and the length direction of the positioning part 32 is parallel to the translational direction of the edge body, the corresponding plug 322 can be coaxially arranged with the edge body, and the plug 322 faces the edge body, so that the edge body in the translational state can be inserted to realize the storage of the edge body.

[0097] In this embodiment, the end face of the inlet of the insert 322 adopts a concave structure to guide the edge body and ensure the continuous use of multiple positioning parts 32. Specifically, after the edge body is housed in the insert 322 and cut by the cross-cutting component, the first rotating motor 312 drives the rotating roller 311 to rotate, so that another positioning part 32 is aligned with the edge body, allowing the subsequent edge body to enter another insert 322. When the edge body enters the insert 322, it will first connect with the concave structure of the insert 322 so that the insert 322 and the edge body are coaxially set, thus optimizing the way the edge body is inserted into the insert 322.

[0098] In some embodiments, such as Figure 20 As shown, a strip groove 321 is provided on the side of the positioning part 32 facing away from the rotating roller 311, and the strip groove 321 passes through one end of the positioning part 32 along the axial direction of the rotating roller 311; in order to make the processing position of the cross-cutting component on the edge body closer to the suction component 2, so that the debris formed by the cross-cutting is separated from the edge body by the suction component 2, the through surface of the strip groove 321 is the end of the positioning part 32 facing the vertical cutting component 1.

[0099] The insert 322 is adapted to slide into the strip groove 321 along the axial direction of the roller 311. Specifically, the bottom of the strip groove 321 is provided with a groove body with a vertical cross section of T. The side of the insert 322 is provided with a T-shaped sliding strip that matches the groove body, so that after the insert 322 is inserted into the strip groove 321, the sliding strip and the groove body are connected to prevent the insert 322 from exiting along the opening of the strip groove 321.

[0100] Furthermore, after the insert 322 is inserted into the strip groove 321, a portion of the insert 322 extends to the outside of the positioning part 32 to be coaxially arranged with the edge body. By adopting this feature, the portion embedded between the edge body and the vertical section of the plate is the sidewall of the insert 322, and the positioning part 32 is located outside this area to avoid providing excessive torsional force to the edge body, thereby avoiding affecting the vertical section of the plate.

[0101] After the insert 322 is inserted into the slot 321, the opening surface of the insert 322 is flush with the end face through which the slot 321 passes; based on this, in some embodiments, such as Figure 19 and Figure 20 As shown, the cross-cutting assembly includes multiple cross-cutting blades 323 respectively disposed on multiple positioning parts 32. Each cross-cutting blade 323 is slidably connected to the end face through which the strip groove 321 passes, and the end face of the cross-cutting blade 323 facing away from the rotating roller 311 is its cutting surface, so that when the cross-cutting blade 323 moves, it can act on the edge body extending to the outside of the insert 322, thereby realizing the cross-cutting of the edge body, so that the cut edge body remains in the insert 322, and another part of the edge body can be inserted into another insert 322 as the rotating roller 311 rotates.

[0102] A first linear cylinder 324 is provided on the positioning part 32. The power output axis of the first linear cylinder 324 is parallel to the length direction of the positioning part 32 and perpendicular to the sliding direction of the cross-cutting blade 323. The power output end of the first linear cylinder 324 is hinged to a transmission arm 325, and the swing end of the transmission arm 325 is hinged to the cross-cutting blade 323. Both hinge axes are parallel to the extension direction of the cutting surface of the cross-cutting blade 323 (perpendicular to the sliding direction of the cross-cutting blade 323 and parallel to the end face through which the strip groove 321 passes), so that when the first linear cylinder 324 is activated, the transmission arm 325 swings and the cross-cutting blade 323 moves toward or away from the rotating roller 311, thereby realizing automated control and efficient operation of the edge body cross-cutting operation.

[0103] In some embodiments, such as Figures 2 to 7 As shown, the suction assembly 2 includes a suspension 21, two sealed boxes 22, and a suction component 23.

[0104] The suspension 21 is fixedly installed directly above the translational area of ​​the plate, and its length direction is parallel to the width direction of the plate.

[0105] Both sealing boxes 22 are located on the lower side of the suspension 21 and are slidably connected to the suspension 21. The sliding direction is parallel to the length direction of the suspension 21, that is, parallel to the width direction of the plate. Based on this, when the two sealing boxes 22 move towards each other or away from each other, this device can be adapted to waste edge cutting operations with different width requirements.

[0106] It should be noted that, in order to fix the position of the sealing box 22, the following structural design is made: the suspension 21 has a through hole extending in the vertical direction, which extends along the length of the suspension 21 to form a strip structure; the sealing box 22 has a U-shaped slider adapted to this strip structure, which slides into the hole to achieve a sliding connection between the sealing box 22 and the suspension 21. Based on this, a pressure plate is also provided on the upper side of the suspension 21, and the lower side of the pressure plate has an elastic block that can abut against the U-shaped slider; in actual use, by adjusting the preset locking plate on the suspension 21 (the locking plate and the suspension 21 are rotatably connected in the vertical direction to be adapted to rotate to the upper side of the pressure plate and abut against the pressure plate, or rotate to avoid the pressure plate), the pressure plate can be locked or unlocked; the locking plate in the locked state can apply a downward force to the pressure plate to ensure that the sealing box 22 is limited by the action of the elastic block, so as to fix the position of the sealing box 22.

[0107] Both sealed boxes 22 have downwardly extending air inlet pipes 6 for being directed toward the two edge bodies respectively; each air inlet pipe 6 is connected to the sealed box 22 so that the gas in the air inlet pipe 6 can enter the sealed box 22 to form an airflow that can entrain impurities in the area of ​​the air inlet pipe 6.

[0108] The suction component 23 is connected to two sealed boxes 22 to extract the gas inside the sealed boxes 22 so that the sealed boxes 22 are in a negative pressure state. In this embodiment, the suction component 23 includes a suction pump fixed to the outside of the equipment. The suction end of the suction pump is connected to a gas pipe, and the gas pipe is connected to two pipes through a connector. The two pipes are respectively connected to the two sealed boxes 22.

[0109] To prevent impurities in the area oriented towards the air inlet pipe 6 from entering the suction component 23, the air inlet pipe 6 has a first isolation mesh 4 for intercepting coarse particles within the impurities, and the sealed box 22 has a second isolation mesh 5 for intercepting fine particles within the impurities. It should be noted that the reason for distinguishing impurities according to particle size is that this allows for more efficient cleaning of the first and second isolation meshes 4 and 5, thereby improving the stability of the component during use. In other words, after a period of use, by removing, cleaning, and replacing the first and second isolation meshes 4 and 5, blockage by impurities can be prevented, thus avoiding any impact on the operating performance of the suction component 2.

[0110] In some embodiments, such as Figures 8 to 11As shown, an axially extending baffle 61 is provided inside the intake pipe 6 to divide the interior of the intake pipe 6 into a first chamber and a second chamber. In actual use, the first chamber is used for airflow, and the second chamber is used to contain coarse particulate impurities. For this purpose, a storage cover 62 for sealing the second chamber is connected to the lower end of the intake pipe 6. That is, the gas in the area oriented by the intake pipe 6 carries the corresponding impurities into the first chamber, and then the coarse part of the impurities falls into the second chamber and remains on the storage cover 62, while the fine part of the impurities passes through the first isolation mesh 4 and enters the sealed box 22. The outer peripheral surface of this storage cover 62 has a raised ridge, and the corresponding inner surface of the second chamber has a strip-shaped groove into which the raised ridge can be inserted; furthermore, the upper surface of the storage cover 62 has an inner groove for containing coarse particulate impurities, and the lower surface has a handle detachably connected to its surface. In use, the operator can easily remove the storage cover 62 by grasping the handle and applying downward force.

[0111] The partition 61 and the intake pipe 6 adopt a detachable connection structure. Specifically, when the partition 61 is inserted into the intake pipe 6, its lower side is flush with the lower end face of the intake pipe 6. The overlapping side of the partition 61 and the intake pipe 6 has a threaded groove. The intake pipe 6 has a through hole that can communicate with the threaded groove. The intake pipe 6 is also provided with a positioning bolt that can pass through the through hole and can be threadedly connected to the threaded groove.

[0112] It should be noted that, in order to avoid the partition chamber technique from occupying the inlet of the air inlet pipe 6 and to ensure the suction effect of the air inlet pipe 6, in this embodiment, the lower end of the air inlet pipe 6 adopts a funnel-shaped structure with an inner diameter that gradually increases from top to bottom.

[0113] Based on the foregoing, the first isolation net 4 includes a rotating frame 41 and multiple screen plates 42.

[0114] The rotating frame 41 is rotatably mounted on the upper surface of the partition 61 and is connected to a second rotating motor 411. By driving the rotating frame 41 to rotate through the second rotating motor 411, any part of the rotating frame 41 can be positioned in either the first chamber or the second chamber.

[0115] Multiple screen plates 42 are disposed within a rotating frame 41 and are arranged at intervals along the circumference of the rotating frame 41. Specifically, the rotating frame 41 includes an inner rotating disk connected to the upper end face of a partition plate 61, and an outer ring frame fitted around the outer circumference of the inner rotating disk. The outer circumference of the inner rotating disk has multiple isolation rods extending radially outward, and the extended end of each isolation rod is connected to the inner wall of the outer ring frame. Each screen plate 42 is disposed between two adjacent isolation rods, such that the side of the screen plate 42 facing the central axis of the inner rotating disk is connected to the outer wall of the inner rotating disk, the side of the screen plate 42 facing away from the central axis of the inner rotating disk is connected to the inner wall of the outer ring frame, and the two sides of the screen plate 42 facing the circumference of the rotating disk are respectively connected to two isolation rods on both sides.

[0116] By adopting the above technical solution, when the rotating frame 41 rotates, any one of the screen plates 42 is suitable to move to the inside of the second chamber so that the impurities attached to the screen plate 42 fall into the second chamber.

[0117] Each screen plate 42 has a degree of freedom to move along the axial direction (i.e., the vertical direction) of the rotating frame 41; a push assembly 7 is provided in the second chamber, which is used to push the screen plate 42 upward so that the screen plate 42 moves upward; and each screen plate 42 is connected to the rotating frame 41 through an elastic reset member 421, which is used to drive the screen plate 42 to move downward.

[0118] By adopting the above technical solution, after the rotating frame 41 rotates until any one of the screen plates 42 is in the second chamber, the pushing assembly 7 can lift the screen plate 42, and then it falls under the action of the elastic reset member 421 and its own gravity, so as to collide with the rotating frame 41, thereby allowing the coarse particles of impurities attached to the surface of the screen plate 42 to fall off stably. Furthermore, this process will not affect the other rotating frames 41, thus ensuring that the coarse particles of impurities inside the other rotating frames 41 can be stably attached to the corresponding screen plates 42.

[0119] It should be noted that the reason for using the elastic reset component 421 (instead of relying solely on the weight of the screen plate 42) is twofold: firstly, the pushing component 7 can quickly detach from the screen plate 42, thereby ensuring that the screen plate 42 is not affected by the pushing component 7 during reset and thus its impact process is not affected; secondly, the elastic reset component 421 can ensure that the screen plate 42 moves downward, thereby preventing impurities from being embedded on the lower side of the screen plate 42 and affecting its reset process.

[0120] In this embodiment, the elastic reset member 421 is a spring fixed on the upper side of the screen plate 42, which is located between the upper side of the screen plate 42 and the rotating frame 41. When the screen plate 42 is pushed upward by the push assembly 7, the spring changes from a natural state or an elastic compression state to a further elastic compression state to provide greater pressure to the screen plate 42.

[0121] In some embodiments, such as Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown, a reserved groove 611 is provided on the upper surface of the partition 61. The second rotating motor 411 is installed in the reserved groove 611 and is connected to the rotating frame 41 through the transmission shaft 412. Specifically, the power output shaft of the second rotating motor 411 and the rotating shaft of the rotating frame 41 are coaxially arranged and have a gap. The transmission shaft 412 is installed in the gap, and the lower end of the transmission shaft 412 is connected to the power output end of the second rotating motor 411, while the upper end of the transmission shaft 412 is connected to the rotating shaft of the rotating frame 41.

[0122] In this embodiment, in order to facilitate the removal of the second rotating motor 411 (for maintenance, upkeep, etc.), the reserved slot 611 extends through the partition 61 in the vertical direction, and the partition 61 is detachably connected to a support plug that can be embedded in the reserved slot 611 and can also support the second rotating motor 411; when it is necessary to remove the second rotating motor 411, the support plug can be removed.

[0123] Based on the foregoing, the jacking assembly 7 includes two rotating arms 71 and a lifting arm 72.

[0124] Both rotating arms 71 are disposed in the second chamber and are rotatably connected to the partition 61. Specifically, the two rotating arms 71 are spaced apart along the axial direction of the air intake pipe 6, and the rotation axes of the two rotating arms 71 are parallel to each other and perpendicular to the axial direction of the air intake pipe 6.

[0125] The two ends of the lifting arm 72 are connected to the swing ends of two rotating arms 71 respectively to form a cooperative transmission structure. Specifically, when one rotating arm 71 rotates, the position of the lifting arm 72 changes, and the other rotating arm 71 rotates synchronously. In this process, the actively rotating rotating arm 71 plays a transmission role, while the passively rotating rotating arm 71 restricts the movement trajectory of the lifting arm 72, ensuring that the upper end of the lifting arm 72 can move laterally and rise and fall simultaneously, thereby quickly contacting the screen plate 42 and quickly disengaging along an arc trajectory. Compared to vertical lifting, this movement ensures the rapid separation of the lifting arm 72 and the screen plate 42, thereby improving the stability of the process in which the screen plate 42 falls and impacts the rotating frame 41 under the aforementioned spring force.

[0126] To drive the rotating arm 71, one of the rotating arms 71 has a connecting rod 711 coaxially arranged with its rotation axis. The connecting rod 711 passes through the partition 61 and extends into the reserved slot 611. Based on this, a driven helical gear 7111 is coaxially connected to the extended end of the connecting rod 711, and a driving helical gear 4121 meshing with the driven helical gear 7111 is coaxially connected to the transmission shaft 412. When the second rotating motor 411 is started, the transmission shaft 412 is driven to rotate, so that the connecting rod 711 rotates synchronously under the action of the meshing relationship between the driven helical gear 7111 and the driving helical gear 4121, thereby driving the rotation of the rotating arm 71.

[0127] By adopting the above technical solution, the pushing assembly 7 can use the driving force of the rotating frame 41 to lift the screen plate 42. Furthermore, by adjusting the transmission ratio of the driven helical gear 7111 and the driving helical gear 4121, the efficiency of the lifting operation can be controlled, allowing for more precise control over the number of times a single screen plate 42 is pushed by the pushing assembly 7 when passing through the pushing area. In other words, when the transmission ratio is fixed, the number of times a single screen plate 42 is pushed during one rotation is fixed and is not affected by the efficiency of the second rotating motor 411. Compared to using two separate driving components, this not only saves on cost but also improves the stability of the device during use.

[0128] In some embodiments, such as Figures 14 to 18 As shown, the vertical cutting assembly 1 includes a base 11, a vertical cutting blade 12, and a vertical cutting saw disc 13.

[0129] The base 11 has a square structure and is used to fix it to the ground outside the equipment. The upper side of the base 11 has an adjustment seat 111 that is rotatably connected to it in the vertical direction. The adjustment seat 111 and the base 11 have a locking structure 8. Specifically, the locking structure 8 includes a pin that is slidably disposed on the outer side of the adjustment seat 111 in the vertical direction, and a frame that is fixedly disposed on the outer side of the base 11. After the adjustment seat 111 is rotated into position, the outer side of the base 11 and the outer side of the adjustment seat 111 are flush, and the pin can be inserted into the frame to restrict the rotation of the adjustment seat 111 relative to the base 11.

[0130] An mounting plate 112 is slidably disposed on the adjusting seat 111 in the horizontal direction. Specifically, the adjusting seat 111 has an inner cavity and a mounting hole that runs through and communicates with the inner cavity in the horizontal direction. The mounting plate 112 is slidably inserted into this mounting hole in the horizontal direction to achieve a sliding connection relationship between it and the adjusting seat 111.

[0131] Furthermore, the mounting plate 112 is connected to a linear drive component 1121. In this embodiment, the linear drive component 1121 includes a swing plate hinged to the upper side of the mounting plate 112 and a lifting block slidably disposed on the outer side of the adjusting seat 111 in the vertical direction. The swing end of the swing plate is hinged to the lifting block, and the hinge axis is parallel to the hinge axis of the swing plate. Both hinge axes are parallel to the horizontal plane and perpendicular to the sliding direction of the mounting plate 112. A vertical transmission screw is rotatably disposed within the inner cavity of the adjusting seat 111, and this transmission screw is connected to a fourth rotary motor. Correspondingly, the lifting block extends through the adjusting seat 111 and into the inner cavity, and the portion extending into the inner cavity is fixed with a transmission nut threadedly connected to the transmission screw. When the fourth rotary motor is started, the transmission screw rotates, and the corresponding transmission nut drives the lifting block to move in the vertical direction, thereby achieving translational control of the mounting plate 112.

[0132] The vertical cutting blade 12 is disposed at one end of the mounting plate 112 and has a cutting surface set toward the translational direction of the plate to achieve the first vertical cutting method (i.e., knife cutting) of the plate.

[0133] The vertical cutting saw disc 13 is rotatably mounted at the other end of the mounting plate 112 and is connected to a third rotating motor 131. When the third rotating motor 131 is started, the vertical cutting saw disc 13 rotates rapidly to achieve a second vertical cutting method (i.e. sawing) of the board.

[0134] When vertically cutting thin sheets, the first vertical cutting method is used; when vertically cutting thick sheets, the second vertical cutting method is used.

[0135] The two vertical cutting methods can be achieved by changing the orientation of the adjusting seat 111 and locking it through the locking structure 8; the vertical cutting position can be changed under the action of the linear drive component 1121 to ensure that the position can receive the action of the suction component 2, so that the debris formed by cutting can be recycled.

[0136] In some embodiments, such as Figure 15 and Figure 16 As shown, the vertical cutting blade 12 is connected to the mounting plate 112 via a hinge seat 9. Specifically, the hinge seat 9 includes an outer frame fixedly connected to the mounting plate 112, and a rotating disk rotatably disposed inside the outer frame. The outer side of the rotating disk has a connecting arm extending radially outward, and the vertical cutting blade 12 is fixedly disposed at the extension end of the connecting arm. The outer frame has holes spaced circumferentially therein, the rotating disk has a groove that can communicate with any of the holes, and the outer frame has a locking element that can pass through the hole and communicate with the groove.

[0137] By adopting the above technical solution, the vertical cutting blade 12 can swing to a horizontal or vertical state with the central axis of the hinge seat 9 as the axis; when the vertical cutting blade 12 is in the vertical state, the cutting surface of the vertical cutting blade 12 faces the translational direction of the plate, so that it can be used for the first vertical cutting method.

[0138] A blade housing 1122 is slidably disposed on the mounting plate 112; when the vertical cutting blade 12 is in a horizontal state, the blade housing 1122 is adapted to move to fit around the outer periphery of the vertical cutting blade 12, thereby preventing on-site personnel from being scratched by the vertical cutting blade 12 when it is idle.

[0139] Based on the same inventive concept, this application also provides a method for recycling and processing waste edges of sheet metal, which, based on the waste edge recycling and processing system proposed in any of the foregoing claims, includes the following steps:

[0140] A. Before starting the injection molding equipment, turn on the suction assembly 2 to reduce dust in the environment;

[0141] B. Start the injection molding equipment and extrude the sheet backward; at the same time, turn on the two sets of vertical cutting components 1 so that the waste edges on both sides of the sheet are converted into edge bodies;

[0142] C. Adjust the storage component 3 so that the two sets of edge bodies move synchronously with the board and enter the two sets of storage components 3 respectively;

[0143] D. Open the cross-cutting component to separate the edge body located inside the storage component 3 from the board material, and the separated edge body is inside the storage component 3;

[0144] E. Repeat steps C and D.

[0145] The beneficial effects of the waste edge recycling method for board provided in this embodiment are as follows: the pretreatment by the suction component 2 can reduce the total amount of dust in the environment. On the one hand, it can avoid dust from interfering with the recycling of waste edges, and on the other hand, it can reduce the amount of dust adhering to the surface of the board.

[0146] In addition, the suction component 2 plays a role in recycling cutting debris during the process of converting waste edge into edge body, thereby reducing the amount of impurities adhering to the surface of waste edge and maintaining the raw material level of high-quality recycled particles after it is converted into edge body.

[0147] After the edge body is generated, it can enter the storage component 3 as the board moves to isolate it from the outside world and avoid the influence of external impurities on its surface. At the same time, the edge body can be detached after being processed by the cross-cutting component, completing the recycling step. In addition, the cutting debris formed by the cross-cutting component in processing the edge body will be isolated on the outside of the storage component 3, ensuring the cleanliness of the surface of the edge body inside the storage component 3.

[0148] During the continuous recycling of edge bodies, when two adjacent edge body sections separate, their roots interact to cause surface debris to eject in an irregular trajectory, preventing it from completely adhering to the edge body surface and affecting subsequent recycling steps. Based on this, since there is a time interval between the recycling of two adjacent edge body sections (this interval is positively correlated with the maximum length of edge body that the storage component 3 can store), the amount of cutting debris on each edge body section is limited and usually does not adversely affect subsequent processes.

[0149] Compared with existing technologies, this method can effectively reduce the amount of impurities attached to recycled waste edges, improve the recycling quality of board waste edges, and increase the yield of high-quality recycled granules.

[0150] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
