Description

Technical Field

[0001] This invention relates to the technical field of building material processing, and more particularly to the technical field of building material cutting and recycling, specifically an environmentally friendly recycling device for building materials. Background Technology

[0002] Building panels involve a variety of materials such as wood, metal and composite materials. Different materials of building panels correspond to different uses and are widely used in building structural support and decoration. As for wooden formwork, it is used in the construction of cast-in-place concrete structures to form temporary structures for concrete and is responsible for bearing the load of concrete. In order to comply with environmental protection policies and achieve resource recycling, and to reduce construction waste and reduce landfill pressure, it is necessary to recycle and reuse wooden formwork. The recycling method is to trim and refurbish slightly damaged wooden formwork for reuse, and to crush severely damaged wooden formwork for resource utilization.

[0003] For example, Chinese patent CN110405828B discloses an automatic sheet metal cutting device, including a front plate pressing mechanism, a main body, a sheet metal pushing mechanism, an adjustable cutting mechanism, and a backflow prevention and dust collection mechanism. The front plate pressing mechanism is connected to the main body, the main body is connected to the sheet metal pushing mechanism, the main body is connected to the adjustable cutting mechanism, and the main body is connected to the backflow prevention and dust collection mechanism. This device has the functions of cutting sheet metal, positioning and pushing sheet metal, compacting sheet metal, adjusting cutting blades, and dust collection. The device has a reasonable structure and is easy to operate.

[0004] Based on the aforementioned patents and in conjunction with existing solutions and actual production and processing applications, current building material cutting and recycling devices still have some problems, such as: The aforementioned patent uses a plate-pushing mechanism to position and advance the plate, and works in conjunction with an adjustable cutting mechanism to cut the plate. This patent is similar to existing building plate cutting and recycling devices, both of which can only handle simple plate cutting. However, in actual processing, if the waste edges after plate cutting are not processed in real time, they can easily accumulate and affect subsequent operations. In addition, the current method for handling waste edges generated after cutting boards usually involves manually separating the waste edges and then cumbersomely transferring them to waste edge processing equipment. This processing method, which cannot complete the waste edge recycling process in real time during board cutting, adds more cumbersome intermediate steps and increases the workload, thereby reducing the overall processing efficiency.

[0005] Therefore, we propose an environmentally friendly recycling device for building materials to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an environmentally friendly recycling device for building panels, in order to solve the problem mentioned in the background art that the waste edge cannot be recycled in real time during the panel cutting process, which increases the number of cumbersome intermediate steps and reduces the overall processing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly recycling device for building materials, comprising: A rack cabinet, wherein an electric circular saw for cutting edges of sheet metal is installed inside the rack cabinet; Also includes: The conveying mechanism is mounted on the rack cabinet and is used for automatic conveying of the board. The conveying mechanism and the electric circular saw cooperate to automatically cut the waste edges of the board. The conveying mechanism is equipped with a first clamping mechanism for temporarily clamping and positioning the cut waste edges. The second clamping mechanism is positioned directly in front of the first clamping mechanism. The second clamping mechanism clamps the waste edge away from the first clamping mechanism and automatically transports the waste edge into the crushing mechanism for real-time crushing and recycling of the waste edge.

[0008] Preferably, the conveying mechanism includes a main conveying frame and a secondary conveying frame arranged parallel to the main conveying frame. The main conveying frame is rotatably connected with main rollers at equal intervals, and drive rollers are arranged at equal intervals with the main rollers in the main conveying frame. The drive rollers are connected to the first motor through a pulley assembly, and the drive rollers are driven by the first motor to form a rotating structure in the main conveying frame, thereby automatically pushing the plate material to move. The auxiliary conveyor frame is equipped with rotatably connected auxiliary rollers at equal intervals, which assist in the stable conveying of the plate through the cooperation between the auxiliary rollers and the main roller.

[0009] Preferably, the secondary conveyor frame is provided with a fixed-length baffle for controlling the cutting length of the sheet metal, and the fixed-length baffle forms a sliding adjustment structure on the secondary conveyor frame.

[0010] Preferably, the main conveyor frame is driven by the first cylinder to form a lifting structure on the rack cabinet, and the main conveyor frame and the auxiliary conveyor frame form a relative motion structure, and the auxiliary conveyor frame is driven by the second cylinder to form a lifting structure on the rack cabinet.

[0011] Preferably, the first clamping mechanism includes main pressure rollers evenly spaced on the main conveyor frame and secondary pressure rollers evenly spaced on the secondary conveyor frame. The main pressure rollers form a sliding structure on the main conveyor frame, and a spring is installed at the sliding connection between the two. The secondary pressure rollers form a sliding structure on the secondary conveyor frame, and a spring is also installed at the sliding connection between the two. The main pressure roller is arranged in a synchronous motion structure with the main conveyor frame, and the main pressure roller is arranged in a corresponding manner with the auxiliary pressure roller. The auxiliary pressure roller is arranged in a synchronous motion structure with the auxiliary conveyor frame. The cut waste edge is clamped and positioned by the cooperation between the main pressure roller and the auxiliary pressure roller.

[0012] Preferably, a separating blade is provided between the first clamping mechanism and the conveying mechanism to separate the two. The separating blade is fixed to the frame cabinet and is on the same horizontal central axis as the electric circular saw. The separating blade actively separates the plate material from the waste edge after cutting.

[0013] Preferably, the second clamping mechanism includes a housing frame, an upper clamping wheel mirror-arranged about the vertical central axis of the housing frame, and a lower clamping wheel mirror-arranged about the vertical central axis of the housing frame. The housing frame is driven by a third cylinder to form a sliding structure on the rack cabinet. The upper and lower clamping wheels slide synchronously through the housing frame and are connected to the first clamping mechanism by a docking insertion method. The upper and lower clamping wheels form a relative sliding structure on the outer frame. The upper and lower clamping wheels cooperate to clamp and pick up the waste edge in the first clamping mechanism and are used for automatic conveying of the waste edge.

[0014] Preferably, the upper clamping wheel is driven by the first linkage frame to form a sliding structure on the outer shell frame, and the first linkage frame forms a flipping structure inside the outer shell frame; the lower clamping wheel is driven by the second linkage frame to also form a sliding structure on the outer shell frame, and the second linkage frame also forms a flipping structure inside the outer shell frame. The first and second linkage frames are both connected to the push-pull frame in a sliding manner. The first and second linkage frames are driven by the push-pull frame to move synchronously and form a relative flipping structure. The push-pull frame is driven by the fourth cylinder to form a sliding structure on the outer shell frame.

[0015] Preferably, the lower clamping wheel is provided with an integrated gear part, and the gear part in the lower clamping wheel is meshed with the driving gear rotatably connected in the outer casing. The driving gear is meshed with the driven gear rotatably connected in the outer casing. The driven gear is meshed with the gear part integrally provided on the upper clamping wheel. The drive gear and the second motor are connected by a pulley assembly. The drive gear is driven by the second motor to form a rotating structure within the housing frame. Through the transmission cooperation between the drive gear and the driven gear, the rotation direction of the lower clamping wheel on the second linkage frame is opposite to that of the upper clamping wheel on the first linkage frame.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: the environmentally friendly recycling device for building panels integrates the cutting and processing of waste edges of the panels with the crushing and recycling of waste edges in the same equipment, and the integrated process operation. During the cutting process, the waste edges are crushed in real time, which effectively reduces the cumbersome intermediate links such as manual separation and handling and equipment conversion, and improves the overall processing efficiency. 1. The automatic conveying mechanism transports the board material, and the electric circular saw automatically cuts off the waste edges of the board material. The cut waste edges are temporarily clamped and positioned by the first clamping mechanism. After the second clamping mechanism is connected to the first clamping mechanism, it clamps and picks up the waste edges on the first clamping mechanism. The waste edges are then automatically transported to the crushing mechanism for real-time crushing and recycling. The board material waste edge cutting and waste edge crushing and recycling are integrated into the same equipment, and the integrated process effectively reduces the cumbersome intermediate links such as manual separation and handling and equipment conversion, thereby improving the overall processing efficiency. Furthermore, after the second clamping mechanism is connected to the first clamping mechanism, it uses the upper and lower clamping wheels to clamp and pick up the waste edge, and uses the upper and lower clamping wheels that rotate in opposite directions to transport the waste edge to the crushing mechanism. During the cutting of the waste edge of the board, the waste edge is crushed in real time, and the waste edge is directly converted into recyclable scrap. By applying an environmentally friendly treatment method, the resource utilization rate is effectively improved. 2. The main conveyor frame moves on the upper bracket in the machine cabinet under the drive of the first cylinder, while the auxiliary conveyor frame moves on the platform in the machine cabinet under the drive of the second cylinder. The main and auxiliary conveyor frames form a relative motion structure, which allows for free adjustment of the gap between the main and auxiliary rollers. This allows for the limited conveying of plates of different thicknesses. In addition, the fixed-length baffle forms a sliding adjustment structure on the auxiliary conveyor frame, which allows for free adjustment of the gap between the fixed-length baffle and the electric circular saw. This allows for the adaptation to the edge cutting processing needs of different lengths, thus improving the applicability of this building material recycling device. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] This invention provides a technical solution: an environmentally friendly recycling device for building panels. This device addresses the problem that during the cutting and recycling of building panels, the waste edges cannot be recycled in real time, leading to accumulation and affecting operations. Furthermore, it requires manual separation and cumbersome transfer of the waste edges to the waste edge processing equipment, adding unnecessary intermediate steps and reducing overall processing efficiency. The device uses an electric circular saw 2 and a conveying mechanism 3 to automatically cut the waste edges of the panels. A first clamping mechanism 4 then temporarily clamps and positions the cut waste edges. Finally, a second clamping mechanism 5 picks up the waste edges, detaching them from the first clamping mechanism 4. The second clamping mechanism 5 then automatically transports the waste edges to a crushing mechanism 6 for real-time crushing and recycling.

[0021] This technical solution: Please refer to Figures 1-10 An environmentally friendly recycling device for building materials includes a rack cabinet 1, a platform is fixedly installed on the upper side of the rack cabinet 1, an integrated upper bracket is provided on the upper side of the platform, and an integrated front bracket is provided on the front side of the platform. An electric circular saw 2 for cutting the edges of the materials is installed inside the rack cabinet 1. It also includes a conveying mechanism 3 and a second clamping mechanism 5. The conveying mechanism 3 is located at the interval between the platform and the upper bracket in the rack cabinet 1 for automatic conveying of the board. The conveying mechanism 3 and the electric circular saw 2 work together to automatically cut the waste edges of the board. The first clamping mechanism 4 is located on the left side in front of the conveying mechanism 3. The first clamping mechanism 4 is used to temporarily clamp and position the cut waste edges. The second clamping mechanism 5 is located directly in front of the first clamping mechanism 4. The waste edges are clamped and released from the first clamping mechanism 4 by the second clamping mechanism 5. The crushing mechanism 6 is located to the right of the second clamping mechanism 5. The waste edges are automatically conveyed into the crushing mechanism 6 by the second clamping mechanism 5 for real-time crushing and recycling of the waste edges.

[0022] Specifically, in this technical solution, the waste edges of the board are automatically trimmed through the cooperation between the electric circular saw 2 and the conveying mechanism 3. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the conveying mechanism 3 includes a main conveying frame 7 and a secondary conveying frame 8. The main conveying frame 7 has main rollers 9 arranged in parallel at equal intervals, and drive rollers 10 are also arranged in parallel at equal intervals. The drive rollers 10 and the main rollers 9 are arranged at intervals. The secondary conveying frame 8 has secondary rollers 12 arranged in parallel at equal intervals. The main conveying frame 7 is arranged horizontally on the frame cabinet 1, and the main conveying frame 7 and the secondary conveying frame 8 are parallel, so that the main rollers 9, drive rollers 10 and secondary rollers 12 are arranged in parallel. Since the main roller 9 is set to extend downwards on the main conveyor frame 7, the drive roller 10 has the same dimensions as the main roller 9, that is, the drive roller 10 and the main roller 9 are set to be flush. Since the auxiliary roller 12 is set to extend upwards on the auxiliary conveyor frame 8, when the main conveyor frame 7 and the auxiliary conveyor frame 8 are connected, the main roller 9 and the auxiliary roller 12 correspond to each other, and the drive roller 10 also corresponds to the auxiliary roller 12. A gap is reserved between the main roller 9 and the auxiliary roller 12, which is the conveying space for the plate. The plate is inserted into the gap between the main roller 9 and the auxiliary roller 12. Because bearings are fixedly engaged at both ends of the central shaft of the main roller 9, after the main roller 9 is assembled with the main conveyor frame 7, the front and rear ends of the central shaft of the main roller 9, along with the bearings, are respectively inserted into the front and rear side walls of the main conveyor frame 7, thus forming a rotating structure within the main conveyor frame 7. Similarly, because bearings are fixedly engaged at both ends of the central shaft of the auxiliary roller 12, after the auxiliary roller 12 is assembled with the auxiliary conveyor frame 8, the front and rear ends of the central shaft of the auxiliary roller 12, along with the bearings, are respectively inserted into the front and rear side walls of the auxiliary conveyor frame 8, thus forming a rotating structure within the main conveyor frame 7. 2. A rotating structure is formed inside the auxiliary conveyor frame 8. The plate is inserted into the gap between the main roller 9 and the auxiliary roller 12, so that the upper side of the plate is in contact with the main roller 9 and the drive roller 10, and the lower side of the plate is in contact with the auxiliary roller 12. The clamping of the plate by the main roller 9 and the auxiliary roller 12 plays a limiting role, that is, the plate is limited to a horizontal state within the conveying mechanism 3 to prevent deviation and maintain centered movement. In addition, the plate is stably conveyed within the conveying mechanism 3 by the freely rotating main roller 9 and the auxiliary roller 12. Because the rear wall of the main conveyor frame 7 is hollow and serves as a frame box, bearings are fixedly fastened to both ends of the central shaft of the drive roller 10. After the drive roller 10 is assembled with the main conveyor frame 7, the front and rear ends of the central shaft of the drive roller 10, along with the bearings, are respectively inserted into the front and rear walls of the main conveyor frame 7. The rear end of the central shaft extends through the rear wall of the main conveyor frame 7 into the frame box. Furthermore, since the pulley assembly is composed of a toothed belt and pulleys (the pulley assembly is existing technology, and its working and assembly methods are not described in detail), the pulley assembly is housed within the frame box of the main conveyor frame 7. Multiple pulleys are provided, each pulley... For each drive roller 10, the rear end of the central shaft column of the drive roller 10 is sleeved with the pulley and fixed together with bolts. Multiple pulleys are driven by a toothed belt. After the first motor 11 is installed, it is fixed to the outside of the frame box of the main conveyor frame 7 with bolts. Its output end is movably inserted into the frame box of the main conveyor frame 7 and engaged with the pulley in the pulley assembly. When the first motor 11 is started, it is driven by the pulley assembly to drive multiple drive rollers 10 to rotate synchronously in the main conveyor frame 7. The drive rollers 10 and the main roller 9 are arranged at intervals. When the drive rollers 10 rotate, they automatically push the plate to move by friction. Since the right end of the conveying mechanism 3 is the plate entry end, and the left end is the plate exit end, the fixed length baffle 13 is placed on the right side of the front of the auxiliary conveying frame 8 and is set vertically on the auxiliary conveying frame 8. Since both the left and right ends of the auxiliary conveying frame 8 are set with rounded corners, it ensures that the plate and the fixed length baffle 13 can be smoothly connected. When the plate is inserted into the gap between the main roller 9 and the auxiliary roller 12, the waste edge of the plate is in contact with the fixed length baffle 13. When the conveying mechanism 3 automatically conveys the plate, the waste edge of the plate is in contact with the fixed length baffle 13 and slides. The fixed length baffle 13 plays a limiting role for the plate. In addition, the distance formed between the fixed length baffle 13 and the electric circular saw 2 is the cutting edge length of the waste edge in the plate. By limiting the plate with the fixed length baffle 13, the fixed-distance cutting is achieved, which ensures the cutting edge processing accuracy. Since the electric circular saw 2 is an electric cutting tool (where the electric circular saw 2 is existing technology and is not described in detail in the accompanying drawings), it uses an electric motor as a power source to drive the circular saw blade to rotate at high speed to cut the board. Since the electric circular saw 2 is in a vertical state, it is located in the middle of the front side of the conveying mechanism 3. During the automatic conveying of the board, the conveying mechanism 3 supports the board by clamping and limiting the main roller 9 and the auxiliary roller 12 to prevent the board from bouncing when the edge is cut. After the board passes through the electric circular saw 2, the high-speed rotating circular saw blade in the electric circular saw 2 automatically cuts off the waste edge of the board. The cut board continues to be conveyed by the conveying mechanism 3 until it leaves the building board recycling device.

[0023] Meanwhile, in the above technical solution, according to Figure 2 and Figure 3 As shown, since the rack cabinet 1 can be equipped with a dust collection device (which is existing technology and is not described in detail in the accompanying drawings), and since the electric circular saw 2 is assembled on the rack cabinet 1, the circular saw blade of the electric circular saw 2 moves through the through groove on the table of the rack cabinet 1, and the dust collection port of the dust collection device is connected to the through groove on the table of the rack cabinet 1, when the electric circular saw 2 is cutting the board, the dust collection device can effectively collect the wood chips and dust generated at the moment of cutting, greatly reducing the diffusion, thereby providing an environmentally friendly and healthy working environment.

[0024] Meanwhile, in the above technical solution, according to Figure 2 , Figure 3 and Figure 4As shown, an integrated assembly rod is horizontally and forward-facing on the right side of the front of the auxiliary conveyor frame 8. The assembly rods are evenly spaced on the auxiliary conveyor frame 8. The fixed length baffle 13 is connected to the assembly rods in the auxiliary conveyor frame 8 by a movable interlocking manner, so that the fixed length baffle 13 forms a sliding structure on the assembly rod. To adjust the cutting edge length at the waste edge of the board, the fixed length baffle 13 is slidably adjusted on the auxiliary conveyor frame 8, thereby adjusting and controlling the distance between the fixed length baffle 13 and the electric circular saw 2. Since a locking bolt is provided at the connection between the fixed length baffle 13 and the assembly rod in the auxiliary conveyor frame 8, the locking bolt is threaded onto the fixed length baffle 13. After the fixed length baffle 13 slides and adjusts on the assembly rod, the locking bolt is rotated so that the locking bolt presses against the assembly rod, thus locking the fixed length baffle 13 onto the auxiliary conveyor frame 8.

[0025] Meanwhile, in the above technical solution, according to Figure 3 and Figure 4 As shown, since the four corners of the upper side wall of the main conveyor frame 7 are vertically provided with integrated guide rods, and since the four corners of the upper bracket in the rack cabinet 1 are all provided with sleeves that are compatible with the guide rods in the main conveyor frame 7, after the main conveyor frame 7 is assembled with the upper bracket in the rack cabinet 1, the guide rods in the main conveyor frame 7 are movably inserted into the sleeves of the upper bracket in the rack cabinet 1, so that the main conveyor frame 7 is positioned on the upper bracket in the rack cabinet 1 in a movable state. Through the sliding fit between the guide rods and the sleeves, the main conveyor frame 7 is kept running stably along the predetermined trajectory when it moves up and down. Since the first cylinder 14 is symmetrically arranged about the vertical central axis of the main conveyor frame 7, after the first cylinder 14 is installed, it is fixedly mounted on the upper bracket of the rack cabinet 1 by bolts, and its output end moves through the upper bracket of the rack cabinet 1 and is fixedly connected to the upper side wall of the main conveyor frame 7 by bolts. When the first cylinder 14 is started to extend and retract, it drives the main conveyor frame 7 to move up and down on the upper bracket of the rack cabinet 1. Since the auxiliary conveyor frame 8 has integrated guide rods vertically installed at the four corners of the lower side wall, and since the auxiliary conveyor frame 8 has integrated sleeves at the four corners of the middle platform of the rack cabinet 1 that are compatible with the guide rods in the auxiliary conveyor frame 8, after the auxiliary conveyor frame 8 is assembled with the middle platform of the rack cabinet 1, the guide rods in the auxiliary conveyor frame 8 are movably inserted into the sleeves in the middle platform of the rack cabinet 1, so that the auxiliary conveyor frame 8 is positioned in a movable state on the middle platform of the rack cabinet 1, and moves in the same way as the main conveyor frame 7, thus maintaining the stability of the auxiliary conveyor frame 8 during lifting and lowering. Since the second cylinder 15 is symmetrically arranged about the vertical center axis of the auxiliary conveyor frame 8, after the second cylinder 15 is installed, it is fixedly installed in the rack cabinet 1 by bolts, and its output end moves through the middle platform of the rack cabinet 1 and is fixedly connected to the lower side wall of the auxiliary conveyor frame 8 by bolts. When the second cylinder 15 is started to extend and retract, it drives the auxiliary conveyor frame 8 to move up and down on the middle platform of the rack cabinet 1. Since the main conveyor frame 7 moves in the opposite direction to the auxiliary conveyor frame 8, the main conveyor frame 7 and the auxiliary conveyor frame 8 move relative to each other through the drive of the first cylinder 14 and the second cylinder 15, so as to adjust the gap between the main roller 9 and the auxiliary roller 12 to adapt to the processing requirements of plates of different thicknesses.

[0026] Specifically, in this technical solution, the first clamping mechanism 4 performs a temporary clamping and positioning operation on the cut waste edge, according to... Figure 2 , Figure 4 and Figure 6 As shown, the first clamping mechanism 4 is positioned forward and extends beyond the electric circular saw 2, corresponding to the waste edge to be cut in the board. The first clamping mechanism 4 includes a main pressure roller 16 and a secondary pressure roller 17. The main pressure rollers 16 are arranged in parallel and at equal intervals on the main conveyor frame 7, and the main pressure rollers 16 are flush with the main roller 9. The secondary pressure rollers 17 are arranged in parallel and at equal intervals on the secondary conveyor frame 8, and the secondary pressure rollers 17 are flush with the secondary roller 12. When the main conveyor frame 7 and the secondary conveyor frame 8 are connected, the main pressure rollers 16 and the secondary pressure rollers 17 correspond to each other. A gap is also reserved between the main pressure rollers 16 and the secondary pressure rollers 17 to accommodate the board conveying. During the automatic edge cutting operation of the waste edge of the board by the electric circular saw 2 in cooperation with the conveying mechanism 3, the cut waste edge is inserted into the first clamping mechanism 4, that is, the waste edge is inserted into the gap between the main pressure rollers 16 and the secondary pressure rollers 17. Since the main pressure roller 16 is composed of a pressure roller body and a "U"-shaped carrier, the pressure roller body is rotatably connected to the frame cavity of the "U"-shaped carrier through a shaft column. Since the overall structure of the auxiliary pressure roller 17 is the same as that of the main pressure roller 16, the waste edge is inserted into the gap between the main pressure roller 16 and the auxiliary pressure roller 17, so that the upper side of the waste edge is in close contact with the pressure roller body in the main pressure roller 16, and the lower side of the waste edge is in close contact with the pressure roller body in the auxiliary pressure roller 17. The main pressure roller 16 and the auxiliary pressure roller 17 clamp and position the plate. That is, the first clamping mechanism 4 completes the temporary clamping and positioning of the cut waste edge. In addition, during the cutting process, when the plate is stably conveyed in the conveying mechanism 3, the waste edge is stably conveyed in the first clamping mechanism 4 through the pressure roller body that can rotate freely on the main pressure roller 16 and the pressure roller body that can rotate freely on the auxiliary pressure roller 17. Because the main pressure roller 16 has a U-shaped carrier frame with nail-shaped guide rods fixed vertically by bolts, and the nail-shaped guide rods are symmetrically arranged about the vertical central axis of the main pressure roller 16, after the main pressure roller 16 is assembled with the main conveyor frame 7, the nail-shaped guide rods in the main pressure roller 16 move through the frame of the main conveyor frame 7. With the limiting assistance of the tail end of the nail in the nail-shaped guide rod, the main pressure roller 16 is positioned in a movable state on the left side of the front of the main conveyor frame 7. And because the main pressure roller 16 is fixed vertically by bolts, the main pressure roller 16 is positioned in a movable state on the left side of the front of the main conveyor frame 7. A spring 18 is installed at the sliding connection between the wheel 16 and the main conveyor frame 7. After the spring 18 is installed, it is movably sleeved on the nail-shaped guide rod in the main pressure wheel 16. One end of the spring 18 presses against the "U"-shaped carrier in the main pressure wheel 16, and the other end presses against the main conveyor frame 7. Through the elastic support of the spring 18 in the main pressure wheel 16, the pressure wheel body in the main pressure wheel 16 is kept in close contact with the waste edge, thereby effectively assisting the main pressure wheel 16 in clamping and positioning the waste edge. Since the main pressure roller 16 is assembled on the main conveyor frame 7 in the same way as the auxiliary pressure roller 17 is assembled on the auxiliary conveyor frame 8, the nail-shaped guide rod in the auxiliary pressure roller 17 moves through the frame of the auxiliary conveyor frame 8, so that the auxiliary pressure roller 17 is positioned in a movable state on the left side of the front of the auxiliary conveyor frame 8. Since a spring 18 is also installed at the sliding connection between the auxiliary pressure roller 17 and the auxiliary conveyor frame 8, and the arrangement of the spring 18 on the main pressure roller 16 is the same as the arrangement of the spring 18 on the auxiliary pressure roller 17, the elastic support of the spring 18 in the auxiliary pressure roller 17 keeps the pressure roller body in the auxiliary pressure roller 17 in close contact with the waste edge, thereby effectively assisting the auxiliary pressure roller 17 in clamping and positioning the waste edge.

[0027] Meanwhile, in the above technical solution, according to Figure 3 and Figure 6 As shown, since the main pressure roller 16 follows the main conveyor frame 7 to form a synchronous motion structure, and the auxiliary pressure roller 17 follows the auxiliary conveyor frame 8 to form a synchronous motion structure, when the main conveyor frame 7 and the auxiliary conveyor frame 8 move relative to each other and the gap size between the main roller 9 and the auxiliary roller 12 is adjusted, the gap size between the main pressure roller 16 and the auxiliary pressure roller 17 can be adjusted synchronously.

[0028] Meanwhile, in the above technical solution, according to Figure 3 and Figure 6 As shown, since both the main pressure roller 16 and the auxiliary pressure roller 17 are elastically supported by springs 18, when the waste edge is disengaged from the first clamping mechanism 4, the main pressure roller 16 slides on the main conveyor frame 7 with the assistance of the nail-shaped guide rod therein, and the spring 18 on the main pressure roller 16 undergoes elastic deformation. Similarly, the auxiliary pressure roller 17 slides on the auxiliary conveyor frame 8 with the assistance of the nail-shaped guide rod therein, and the spring 18 on the auxiliary pressure roller 17 undergoes elastic deformation. In this way, the main pressure roller 16 and the auxiliary pressure roller 17 are provided with a clearance space, making it easier for the waste edge to disengage from the first clamping mechanism 4.

[0029] Meanwhile, in the above technical solution, according to Figure 2 and Figure 3 As shown, after the material distribution knife 19 is installed, it is vertically fixed to the platform of the machine frame cabinet 1 by bolts. Since the material distribution knife 19 and the auxiliary conveyor frame 8 are connected by a movable interlocking method, when the main conveyor frame 7 and the auxiliary conveyor frame 8 move relative to each other for adjustment, the material distribution knife 19 does not affect the lifting and lowering movement of the auxiliary conveyor frame 8. Since the dividing blade 19 and the circular saw blade in the electric circular saw 2 are on the same horizontal central axis, and the thickness of the dividing blade 19 is greater than the thickness of the circular saw blade in the electric circular saw 2, and since the dividing blade 19 is adapted to the structural shape of the circular saw blade in the electric circular saw 2 and corresponds to the left side of the circular saw blade, and since the dividing blade 19 plays a separating role between the first clamping mechanism 4 and the conveying mechanism 3, when the electric circular saw 2 automatically cuts the waste edge of the board, the dividing blade 19 separates the waste edge from the board, reduces the squeezing of the waste edge on the circular saw blade, and prevents the waste edge from rebounding or clamping the circular saw blade, thereby reducing the risk of the circular saw blade getting stuck. In addition, the separating role of the dividing blade 19 also helps the waste edge to smoothly enter the first clamping mechanism 4.

[0030] Specifically, in this technical solution, the second clamping mechanism 5 performs a clamping and picking operation on the waste edge temporarily clamped on the first clamping mechanism 4, according to... Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the second clamping mechanism 5 is in a vertical state and is arranged parallel to the first clamping mechanism 4. The second clamping mechanism 5 includes an outer shell frame 20, an upper clamping wheel 21, and a lower clamping wheel 22. Since the four corners of the outer shell frame 20 are all fixedly connected with guide rods in a vertical state by bolts, and since the four corners of the front bracket in the rack cabinet 1 are all integrally set with sleeves that are compatible with the guide rods in the outer shell frame 20, after the outer shell frame 20 is assembled with the front bracket in the rack cabinet 1, the guide rods in the outer shell frame 20 move through the sleeves of the front bracket in the rack cabinet 1, so that the outer shell frame 20 is positioned on the front bracket in the rack cabinet 1 in a movable state. Through the sliding cooperation between the guide rods and the sleeves, the outer shell frame 20 is kept to move stably along a predetermined trajectory when it slides. Since the third cylinder 23 is installed on the front bracket in the rack cabinet 1 by bolts, and its output end moves through the front bracket in the rack cabinet 1 and is fixedly connected to the outer shell frame 20 by bolts, the third cylinder 23 is started to extend and operate, driving the outer shell frame 20 to slide towards the first clamping mechanism 4 on the front bracket in the rack cabinet 1. Conversely, the outer shell frame 20 is started to retract and operate, driving the outer shell frame 20 to slide away from the first clamping mechanism 4 on the front bracket in the rack cabinet 1. Since the overall structure of the upper clamping wheel 21 is the same as that of the lower clamping wheel 22, taking the docking method of the upper clamping wheel 21 with the main pressure roller 16 as an example, the length of the upper clamping wheel 21 is greater than the length of the main pressure roller 16, and the upper clamping wheel 21 can be completely inserted between two adjacent main pressure rollers 16. The docking method of the lower clamping wheel 22 with the auxiliary pressure roller 17 is the same. Furthermore, since the upper clamping wheel 21 and the lower clamping wheel 22 are on the same vertical central axis, and both the upper clamping wheel 21 and the lower clamping wheel 22 are mirror images of each other about the vertical central axis of the outer casing 20, and the upper clamping wheel 21 and the lower clamping wheel 22 are respectively connected to the main pressure roller 16... The main pressure roller 16 and the auxiliary pressure roller 17 are arranged in parallel. The upper clamping roller 21 is offset from the main pressure roller 16, corresponding to the middle position of two adjacent main pressure rollers 16. The lower clamping roller 22 is offset from the auxiliary pressure roller 17, corresponding to the middle position of two adjacent auxiliary pressure rollers 17. When the outer shell frame 20 is driven to slide towards the first clamping mechanism 4 for docking, the outer shell frame 20 drives the upper clamping roller 21 and the lower clamping roller 22 to slide synchronously, so that the upper clamping roller 21 docks and inserts between two adjacent main pressure rollers 16, and the lower clamping roller 22 docks and inserts between two adjacent auxiliary pressure rollers 17. Since the push-pull frame 26 is mirrored about the vertical central axis of the outer shell frame 20, the two push-pull frames 26 correspond to the two sets of first linkage frames 24 and second linkage frames 25 respectively. Since the push-pull frame 26 is arranged in a "V" shape, it is divided into upper and lower frames. The middle of the push-pull frame 26 is provided with an integrated wedge-shaped positioning block, and an integrated connecting block is provided on the wedge-shaped positioning block. Since the shell cavity wall of the outer shell frame 20 is provided with a wedge-shaped groove that matches the wedge-shaped positioning block in the push-pull frame 26, after the push-pull frame 26 is assembled with the outer shell frame 20, the wedge-shaped positioning block in the push-pull frame 26 is movably locked in the wedge-shaped groove in the outer shell frame 20, and the connecting block on the wedge-shaped positioning block moves through the wedge-shaped groove in the outer shell frame 20 and extends outward, so that the push-pull frame 26 is positioned in a movable state within the outer shell frame 20. Since the fourth cylinder 27 is a dual-output cylinder, with each output end corresponding to a push-pull frame 26, after the fourth cylinder 27 is installed, it is fixedly connected to the outer casing 20 by bolts, and its output end is fixedly connected to the connecting block in the push-pull frame 26 by bolts. When the fourth cylinder 27 is activated to retract, it drives the push-pull frame 26 to slide on the outer casing 20. Conversely, when the fourth cylinder 27 is activated to extend, it drives the push-pull frame 26 to return to its original position and slide on the outer casing 20. Because the shell cavity wall of the outer casing 20 is provided with an integrated shaft column, which is symmetrically arranged about the horizontal central axis of the outer casing 20, corresponding to the first linkage frame 24 and the second linkage frame 25 respectively. Furthermore, the first linkage frame 24 has a "V" shaped structure, divided into an input frame and an output frame. The input frame has a through-type sliding groove. The overall structure of the first linkage frame 24 is the same as that of the second linkage frame 25. Additionally, because the upper and lower ends of the push-pull frame 26 are provided with integrated pins, the push-pull mechanism... After the frame 26 is connected to the first linkage frame 24, the pin on the upper frame is movably inserted into the slide groove on the frame in the first linkage frame 24. After the push-pull frame 26 is connected to the second linkage frame 25, the pin on the lower frame is movably inserted into the slide groove on the frame in the second linkage frame 25. When the push-pull frame 26 is driven to slide, the pin in its upper frame slides on the frame in the first linkage frame 24, and the pin on its lower frame slides on the frame in the second linkage frame 25, simultaneously pushing the first linkage frame 24 and the second linkage frame 25 to rotate. Since the first linkage frame 24 is fixedly connected to the corner with a bearing, after the first linkage frame 24 is installed, its corner and bearing are movably sleeved on the shaft in the outer shell frame 20. The assembly method of the first linkage frame 24 on the outer shell frame 20 is the same as the assembly method of the second linkage frame 25 on the outer shell frame 20. Since the first linkage frame 24 and the second linkage frame 25 are arranged in opposite directions, after the first linkage frame 24 and the second linkage frame 25 are pushed, they both form a flipping structure on the outer shell frame 20, and the first linkage frame 24 and the second linkage frame 25 form a relative flipping structure. Because the outer shell 20 has a through-shaped arc-shaped groove on its cavity wall, the center of the arc-shaped groove coincides with the axis of the central column of the outer shell 20. Furthermore, because the upper clamping wheel 21 has an integrated column at its center, with a bearing fixedly attached to the column, after the upper clamping wheel 21 is assembled with the first linkage frame 24, the central column of the upper clamping wheel 21 moves through the arc-shaped groove in the outer shell 20. The central column, along with the bearing, is movably inserted into the output frame of the first linkage frame 24, making the upper clamping wheel 21 flexible. The upper clamping wheel 21 is positioned on the first linkage frame 24. Since the assembly method of the upper clamping wheel 21 and the first linkage frame 24 is the same as the assembly method of the lower clamping wheel 22 and the second linkage frame 25, the lower clamping wheel 22 is positioned on the second linkage frame 25 in a movable state. When the first linkage frame 24 and the second linkage frame 25 are flipped relative to each other, the first linkage frame 24 drives the upper clamping wheel 21 to move synchronously, and the second linkage frame 25 drives the lower clamping wheel 22 to move synchronously, so that the upper clamping wheel 21 and the lower clamping wheel 22 slide relative to each other, forming a clamping action. When the upper clamping wheel 21 and the lower clamping wheel 22 are inserted into the first clamping mechanism 4, the upper clamping wheel 21 and the lower clamping wheel 22, through relative sliding movement, clamp and pick up the waste edge temporarily clamped and positioned in the first clamping mechanism 4. The third cylinder 23 is activated to retract and operate, so that the outer shell frame 20 moves away from the first clamping mechanism 4 and returns to its original position, and the upper clamping wheel 21 and the lower clamping wheel 22 clamp the waste edge and disengage from the first clamping mechanism 4.

[0031] Specifically, in this technical solution, the waste edge is automatically conveyed to the crushing mechanism 6 by the second clamping mechanism 5 for real-time crushing and recycling. Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, the pulley assembly is housed in the cavity of the housing frame 20. The upper and lower pulleys are rotatably connected to the cavity wall of the housing frame 20 via bearings. The drive gear 28 is equipped with an integrated pulley, which is co-centered with the drive gear 28. Multiple pulleys are driven by a toothed belt. The second motor 30 is bolted to the housing frame 20 after installation. Its output end is bolted to the pulley in the pulley assembly. When the second motor 30 is started, it drives the drive gear 28 to rotate through the pulley assembly. Since the driven gear 29 has a bearing fixedly attached to its center position, after the driven gear 29 is installed, it is movably sleeved on the central shaft of the housing frame 20 along with the bearing. Since the specifications and dimensions of the driven gear 29 are the same as those of the driving gear 28, and the central position of the driving gear 28 has a bearing fixedly attached to it, after the driving gear 28 is installed, it is movably sleeved on the central shaft of the housing frame 20 along with the bearing. Since the driven gear 29 and the driving gear 28 are meshed together, when the driving gear 28 is driven, through the meshing action, the driving gear 28 rotates within the housing frame 20, and the driven gear 29 rotates within the housing frame 20. At this time, the rotation direction of the driven gear 29 is opposite to the rotation direction of the driving gear 28. Since the upper clamping wheel 21 is movably positioned on the output frame of the first linkage frame 24, a gear part with the same center is integrally arranged on the shaft of the upper clamping wheel 21. The gear part of the upper clamping wheel 21 is meshed and connected with the driven gear 29. Since the lower clamping wheel 22 is movably positioned on the output frame of the second linkage frame 25, a gear part with the same center is integrally arranged on the shaft of the lower clamping wheel 22. The gear part of the lower clamping wheel 22 is meshed and connected with the driving gear 28. When the driving gear 28 and the driven gear 29 rotate, through the meshing action, the upper clamping wheel 21 is driven to rotate on the first linkage frame 24, and the lower clamping wheel 22 is driven to rotate on the second linkage frame 25, so that the upper clamping wheel 21 and the lower clamping wheel 22 rotate in opposite directions. Since the upper clamping wheel 21 and the lower clamping wheel 22 are both gear-shaped, when the upper clamping wheel 21 and the lower clamping wheel 22 clamp and pick up the waste edge, the upper clamping wheel 21 and the lower clamping wheel 22 rotate in opposite directions, forming a biting effect on the waste edge. The friction force is used to drive the waste edge to move, ensuring stable conveying. Since the crushing mechanism 6 is an existing roller crusher (which is prior art and not described in detail in the accompanying drawings), after the upper clamping wheel 21 and the lower clamping wheel 22 clamp and pick up the waste edge, the outer casing 20 returns to its original position and slides, causing the waste edge to disengage from the first clamping mechanism 4 and correspond to the crushing mechanism 6. The upper clamping wheel 21 and the lower clamping wheel 22 rotate in opposite directions, automatically conveying the waste edge into the crushing mechanism 6. The crushing mechanism 6 crushes the waste edge by squeezing it through two oppositely rotating rollers.

[0032] Meanwhile, in the above technical solution, according to Figure 8 , Figure 9 and Figure 10 As shown, the rotation center of the first linkage 24 coincides with the rotation center of the driven gear 29. When the first linkage 24 drives the upper clamping wheel 21 to slide, the upper clamping wheel 21 can move around the driven gear 29, so that the gear part in the upper clamping wheel 21 and the driven gear 29 are always meshed. The rotation center of the second linkage 25 coincides with the rotation center of the driving gear 28, and the gear part in the lower clamping wheel 22 is also always meshed with the driving gear 28.
