Description

Technical Field

[0001] This invention relates to the field of sheet metal production equipment technology, specifically to an integrated conveying, sawing, and sealing machine. Background Technology

[0002] In the continuous process of industrialized gypsum board production, from the formation of gypsum slurry into board blanks to the final finished board that meets market standards, alignment, trimming, and edge wrapping are key processes to ensure the dimensional accuracy and edge integrity of the board.

[0003] In current mainstream gypsum board production lines, the trimming and edge-wrapping processes generally use two independent machines. The trimming station requires a separate gypsum board sawing device, while the edge-wrapping station is equipped with a corresponding gypsum board edge-wrapping machine. A transfer device is needed between each station, and the boards need to be transferred and transported between them. This transfer efficiency is low, resulting in low overall production efficiency. In the existing edge-wrapping process, during the transport of boards at the edge-wrapping station, a hard impact method is usually used to maintain the required spacing between adjacent boards. This reduces the yield rate, and the boards may tilt during the hard impact process, affecting the edge-wrapping effect. A dedicated transfer device and two separate sets of equipment are required, leading to high equipment costs. Furthermore, the two machines occupy a large area, resulting in low space utilization and increasing the company's infrastructure and layout costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated conveying, sawing, and sealing machine.

[0005] To achieve the above objectives, the technical solution of the present invention is: a conveying saw sealing integrated machine, comprising a support frame, a conveying mechanism, an alignment mechanism, an edge trimming mechanism, and an edge wrapping mechanism;

[0006] The support frame is equipped with a conveying mechanism for conveying the sheet metal;

[0007] The conveying mechanism is provided with an alignment mechanism for positioning and aligning the plates, an edge trimming mechanism for cutting the plates, and an edge banding mechanism for sealing the plates on both sides in sequence.

[0008] The conveying mechanism includes a conveying track, an alignment conveying mechanism, an edge trimming conveying mechanism, and an edge wrapping conveying mechanism. The alignment conveying mechanism, the edge trimming conveying mechanism, and the edge wrapping conveying mechanism are arranged near the conveying track along the conveying direction of the board. The edge trimming conveying mechanism has a stroke intersection with the alignment conveying mechanism and the edge wrapping conveying mechanism, respectively.

[0009] When the sawing and sealing machine is working,

[0010] The alignment conveyor mechanism drives the sheet material into the alignment station, and the alignment mechanism aligns the sheet material.

[0011] After the board is aligned, the alignment conveyor and the trimming conveyor work together to move the board into the trimming station, where the trimming mechanism trims the edges of the board.

[0012] When the trimming conveyor reaches a certain distance from the edge-wrapping conveyor, the edge-wrapping conveyor starts operating and conveys the board to complete the edge-wrapping and cutting work.

[0013] Furthermore, the alignment conveying mechanism is connected to a lifting drive mechanism, which can drive the end or the whole of the alignment conveying mechanism to move up and down. When the conveying surface of the alignment conveying mechanism is in a horizontal conveying state, its horizontal height is higher than that of the conveying track.

[0014] The trimming and conveying mechanism includes several pusher assemblies, which are used to push the sheet material to move along the sheet material conveying direction.

[0015] When the sawing and sealing machine is working,

[0016] First, the alignment conveyor mechanism drives the sheet material into the alignment station;

[0017] The end of the alignment conveyor or the entire structure descends, the sheet is placed on the conveyor track, and the alignment mechanism aligns the sheet;

[0018] After the plates are aligned, the end or the entire structure of the alignment conveying mechanism rises, and the alignment conveying mechanism drives the plates to move; at the same time, the push plate assembly of the trimming conveying mechanism pushes the plates to move, and under the combined action of the alignment conveying mechanism and the push plate assembly of the trimming conveying mechanism, the plates enter the trimming station.

[0019] The trimming mechanism cuts and trims the edges of the sheet material, and the pusher assembly of the trimming conveyor pushes the sheet material along the conveyor track. When the pusher assembly pushes the sheet material a certain distance away from the edge-wrapping conveyor, the edge-wrapping conveyor starts to run. When a portion of the sheet material has completed the edge-wrapping operation, the edge-wrapping conveyor stops running.

[0020] When the next set of boards is conveyed to a certain distance from the edge-sealing conveyor, the edge-sealing conveyor restarts, the edge-sealing mechanism completes the edge-sealing operation of the boards, and the boards enter the next workstation.

[0021] Furthermore, the alignment conveying mechanism includes an alignment conveyor belt and an alignment drive device for controlling the rotation of the alignment conveyor belt. The alignment conveyor belt is connected to a lifting drive mechanism at its conveying end or bottom. The lifting drive mechanism controls the alignment conveyor belt to rotate around the conveying start end or controls the alignment conveyor belt to move up and down.

[0022] Furthermore, the pusher plate assembly is evenly arranged on the conveyor chain, and a conveyor sprocket that cooperates with the conveyor chain is provided inside the conveyor chain. A trimming drive device for controlling the rotation of the conveyor sprocket is provided on one side of the conveyor sprocket. The pusher plate assembly includes a base arranged on the conveyor chain, a pusher plate is hinged to the base, and rollers are provided on both sides of the pusher plate. A guide rail is provided inside the conveyor track, and the rollers of the pusher plate assembly can move within the guide rail of the conveyor track.

[0023] Furthermore, a trimming roller for pressing the plate is provided on one side of the trimming mechanism.

[0024] Furthermore, the edge-sealing conveyor mechanism includes an edge-sealing conveyor belt and an edge-sealing drive device for controlling the rotation of the edge-sealing conveyor belt, and a plurality of edge-sealing pressure rollers are arranged above the edge-sealing conveyor belt.

[0025] Furthermore, the edge-binding conveyor belt is provided with a first support and a second support. One end of the second support is hinged to the support frame and / or the first support, and the other end is connected to the lifting drive component. When the second support descends, the front end of the edge-binding sheet falls into the next work station, and the rear end falls onto the conveyor track.

[0026] Furthermore, a conveying drive wheel is provided at the top of the end of the edge-binding conveying mechanism, and a pressure wheel drive device for controlling the movement of the conveying drive wheel is provided at the top of the conveying drive wheel; when the sheet material for edge-binding is completed and conveyed to the next work station, the conveying drive wheel provides pressure to the sheet material, and the sheet material for edge-binding enters the next work station.

[0027] Furthermore, the conveying track includes two parallel tracks for providing support during the conveying of the sheet material.

[0028] Furthermore, a support plate is provided in the middle of the support frame, and several sets of pulleys are provided at the rear end of the support plate.

[0029] Furthermore, a position sensor for detecting the state of the sheet material is provided at the inlet end of the conveying mechanism.

[0030] The beneficial effects achieved by this invention are as follows:

[0031] This invention enables simultaneous alignment, trimming, and edge banding of sheet metal on a single sawing and sealing machine. Through continuous power connection of the conveying mechanisms (the alignment conveyor feeds material to the trimming conveyor, which in turn connects directly to the edge banding conveyor), it achieves seamless, gapless processing of the sheet metal, improving production efficiency and overall production capacity. Simultaneously, it reduces equipment costs, increases space utilization, significantly reduces the area occupied by the equipment, and lowers enterprise infrastructure and layout costs. After the alignment process, the sheet metal moves under the combined action of the pusher components of the alignment and trimming conveyors, increasing the acceleration force at startup and improving conveying efficiency. Once the pusher components have pushed the sheet metal a certain distance from the edge banding conveyor, the edge banding conveyor begins operation. It stops when a portion of the sheet metal has completed the edge banding process, improving transfer efficiency and preventing collisions between multiple sheets, thus avoiding hard impacts and increasing the yield. It also meets the spacing requirements between adjacent sheets at the edge banding station. Flexible control prevents sheet metal tilting caused by hard impacts, ensuring the edge banding effect and further improving the yield.

[0032] 2. This invention integrates the alignment mechanism, trimming mechanism, and edge-wrapping mechanism into the same support frame. Through the intersection design of the conveying mechanism's stroke, the entire process of "alignment-trimming-edge-wrapping" can be completed in a single device without the need to allocate separate workstations for each process. Compared with traditional solutions, the production line occupies less space, making it particularly suitable for small and medium-sized workshops with limited space, directly reducing the initial investment costs for enterprise factory construction and equipment layout.

[0033] 3. The trimming conveying mechanism of the present invention adopts a trimming servo motor to independently control the conveying sprocket. When the position sensor detects a movement deviation in the left and right push plate assemblies, the control system can receive the deviation signal in real time and adjust the speed of the trimming servo motor on the offset side separately to make the offset push plate assembly produce a compensating movement and restore the synchronization with the trolley on the other side. The entire correction process does not require machine stoppage, which avoids the scrapping of the sheet metal caused by machine stoppage and ensures the continuous operation of the production line, significantly reducing the production loss of the enterprise.

[0038] To better understand the purpose, structure, and function of this invention, the following detailed description of an integrated conveying saw sealing machine is provided in conjunction with the accompanying drawings.

[0039] like Figures 1 to 3 As shown, a conveyor saw sealing integrated machine includes a support frame 1 and a control system.

[0040] The support frame 1 is equipped with a conveying mechanism 2 for conveying the board material. On both sides of the conveying mechanism 2, there are an alignment mechanism 3 for aligning the board material, an edge trimming mechanism 4 for cutting the board material, and an edge banding mechanism 5 for sealing the board material.

[0041] The conveying mechanism 2 includes a conveying track 11 mounted on the support frame 1 to support the sheet metal. The conveying track 11 includes two parallel tracks that provide support during sheet metal conveying. Near the conveying track 11, along the conveying direction of the sheet metal, are an alignment conveying mechanism 21, an edge trimming conveying mechanism 22, and an edge wrapping conveying mechanism 23. The alignment conveying mechanism 21 and the edge trimming conveying mechanism 22 intersect in their strokes, as do the edge trimming conveying mechanism 22 and the edge wrapping conveying mechanism 23. The strokes of these three mechanisms overlap, ensuring that the sheet metal receives stable power throughout the entire "alignment-edge trimming-edge wrapping" conveying process, preventing sheet metal stagnation, shifting, or decreased processing accuracy due to power interruption.

[0042] The horizontal height of the alignment conveyor 21 is higher than that of the conveyor track 11. Specifically, the height of the alignment conveyor 21 is slightly higher than that of the conveyor track 11, so that the alignment conveyor 21 can smoothly transport the board into the trimming conveyor 22.

[0043] The alignment conveyor mechanism 21, as a pre-processing unit in the sheet metal processing flow, provides reliable pre-positioning assurance for the sheet metal to enter subsequent precision processing through dynamic adjustment and power transmission coordination. It includes an alignment conveyor belt 211 and an alignment drive device that controls the rotation of the alignment conveyor belt 211. The alignment drive device is preferably an alignment servo motor 212. The end of the alignment conveyor belt 211 is connected to a lifting drive mechanism. The connection between the alignment conveyor belt 211 and the lifting drive mechanism is hinged. The lifting drive mechanism is preferably an alignment lifting cylinder 213. The alignment lifting cylinder 213 controls the end of the alignment conveyor belt 211 to rotate around the beginning of the conveyor.

[0044] The conveying start of the alignment conveyor belt 211 is connected to the support frame 1, and the conveying end is movably connected to the support frame 1 through a hinge structure, forming a rotatable adjustable fulcrum. The alignment servo motor 212 serves as a power source, driving the alignment conveyor belt 211 continuously through a transmission assembly, providing stable conveying power to the sheet material and ensuring that the sheet material maintains a preset movement rhythm on the conveyor belt. The alignment servo motor 212 can adjust the conveying speed of the alignment conveyor belt 211 in real time according to the operating rhythm of the subsequent alignment mechanism 3 and trimming conveying mechanism 22, ensuring that the sheet material conveying rate is precisely matched with the downstream process rate, avoiding sheet material compression or excessive gaps due to speed differences.

[0045] At the bottom of the conveyor end of the alignment conveyor belt 211, an alignment lifting cylinder 213 is connected. The fixed end of the alignment lifting cylinder 213 is hinged to the support frame 1, and the telescopic end is connected to the conveyor end of the alignment conveyor belt 211. By extending and retracting the telescopic end of the alignment lifting cylinder 213, the end of the conveyor belt can be driven to rotate up and down around the hinge point at the beginning. When it is necessary to adjust the posture of the alignment conveyor belt 211, the telescopic end of the alignment lifting cylinder 213 extends, which will apply an upward thrust to the end of the alignment conveyor belt 211. At this time, the adjustment fulcrum of the conveyor end rotates upward around the hinge axis, driving the end of the alignment conveyor belt 211 to rise, so that the conveyor belt is kept in a horizontal state to meet the receiving requirements of the upstream plate. When the telescopic end of the alignment lifting cylinder 213 retracts, the adjustment fulcrum rotates downward around the hinge axis, driving the end of the alignment conveyor belt 211 to descend. At this time, the end of the alignment conveying mechanism 21 is tilted downward and its height is lower than that of the conveying track 11, so that the plate stays on the conveying track 11, which facilitates the alignment of the plate. By adjusting the flexible rotation of the fulcrum and the coordinated action of the alignment lifting cylinder 213, the overall tilt angle of the alignment conveyor belt 211 can be adjusted to ensure that the alignment conveyor belt 211 conveys the plate when it is in a horizontal state and aligns the plate when it is in an inclined state.

[0046] When the sheet material enters the alignment conveyor mechanism 21 from the upstream conveying stage, the position sensor 14 installed in the entrance area detects the presence of the sheet material. The position sensor 14 is preferably a photoelectric switch, and it transmits a signal to the control system. After receiving the signal, the control system controls the alignment lifting cylinder 213 to operate according to the preset program instructions, so that the end of the alignment conveyor belt 211 is at the same horizontal height as the beginning, ensuring that the entire conveying plane remains flat.

[0047] Once the sheet material enters the working range of the alignment mechanism 3 under the continuous conveying of the alignment conveyor belt 211, the control system will again instruct the alignment lifting cylinder 213 to operate. At this time, the telescopic end of the alignment lifting cylinder 213 retracts, causing the end of the alignment conveyor belt 211 to rotate downwards, causing the alignment conveyor belt 211 to disengage from the sheet material surface and reach a power failure state. This design ensures that the alignment conveyor belt 211 no longer provides conveying power to the sheet material, causing the sheet material to lose its forward momentum and stably stop within the positioning area of ​​the alignment mechanism 3. The alignment mechanism 3 then performs positioning operations on the sheet material in the left-right and front-back directions. After the alignment mechanism 3 completes the alignment work of the sheet material, the control system will instruct the alignment lifting cylinder 213 to rotate the alignment conveyor belt 211 back to a horizontal state, restoring the contact between the conveyor belt and the sheet material. Simultaneously, the pusher assembly 224 of the trimming conveyor mechanism 22 begins to operate, applying a pushing force to the sheet material. At this point, the conveying power of the aligned conveyor belt 211 and the pushing force of the pusher assembly 224 work together to drive the plate to start. The superposition of the dual power significantly improves the starting speed of the plate, effectively shortens the transition time of the plate from stationary to stable conveying, and thus improves the plate conveying efficiency, laying the foundation for the speed-up of the entire production line.

[0048] The alignment conveyor belt 211 of the alignment conveyor mechanism 21 mainly plays two roles during equipment operation. The first role is reflected in the coordinated acceleration of the sheet material: after the sheet material is positioned in the alignment mechanism 3, when the pusher assembly 224 of the trimming conveyor mechanism 22 is ready to push the sheet material to the trimming station, the control system will instruct the alignment lifting cylinder 213 to operate, lifting the alignment conveyor belt 211 upwards, so that the surface of the conveyor belt is in close contact with the bottom surface of the sheet material. At this time, the alignment conveyor belt 211 and the pusher assembly 224 operate synchronously, jointly applying conveying power to the sheet material. The alignment conveyor belt 211 can share the acceleration force of the pusher assembly 224 when the sheet material starts, greatly reducing the acceleration resistance of the pusher assembly 224, allowing the pusher assembly 224 to reach the preset uniform speed conveying state more quickly, avoiding the problem of slow acceleration caused by excessive single power load, and is more efficient than existing production process equipment. The second function is reflected in the receiving and conveying of the boards: the conveyor track 11 of the sawing machine itself does not have the power to actively convey the boards. When the boards enter this sawing machine from the previous conveyor line, it mainly relies on the conveying power of the alignment conveyor belt 211 to smoothly and accurately send the boards into the positioning position of the alignment mechanism 3, ensuring that the boards can accurately enter the subsequent alignment process and avoiding the boards from staying on the track due to insufficient receiving power, which would affect the continuous operation of the production line.

[0049] In another embodiment, the alignment conveyor mechanism 21 includes an alignment conveyor belt 211 and an alignment servo motor 212 that controls the rotation of the alignment conveyor belt 211. A lifting drive mechanism that controls the lifting and lowering of the alignment conveyor belt 211 is provided at the bottom of the alignment conveyor belt 211. In this embodiment, the lifting drive mechanism uses an alignment lifting cylinder 213, whose fixed end is rigidly connected to the support frame 1, and whose telescopic end is fixed to the support frame at the bottom of the alignment conveyor belt 211 via a connector, forming a stable lifting transmission structure. The alignment conveyor belt 211 moves up and down as a whole under the drive of the alignment lifting cylinder 213. After rising, the alignment conveyor belt 211 is in a horizontal conveying state, its height higher than the conveying track 11, used for conveying the sheet metal. After falling, the alignment conveyor belt 211 is in a horizontal avoidance state, its height lower than the conveying track 11, used to avoid the sheet metal, allowing the sheet metal to fall onto the conveying track 11 for easy alignment. The alignment servo motor 212 serves as a power source, driving the alignment conveyor belt 211 to operate continuously through the transmission components, providing stable conveying power to the sheet metal and ensuring that the sheet metal maintains a preset movement rhythm on the conveyor belt.

[0050] The trimming conveyor mechanism 22 includes a conveyor chain 221. To ensure seamless connection of the sheet metal between processes, the travel of the conveyor chain 221 intersects with the travel of the upstream alignment conveyor belt 211. When the sheet metal is output from the end of the alignment conveyor belt 211, it can directly enter the effective range of the conveyor chain 221 without waiting or transfer, avoiding sheet metal offset or power interruption caused by process intervals. Several push plate assemblies 224 are evenly arranged on the conveyor chain 221 at fixed intervals. Each push plate assembly 224 is connected to the chain through a base 2241 to ensure synchronous movement with the chain. The push plate 2242 is connected to the base 2241 through a hinge structure, so that the push plate 2242 can adaptively adjust its angle according to the flatness of the rear end of the sheet metal, always maintaining a tight fit. Rollers 2243 are arranged on both sides of the push plate 2242. The rollers 2243 are adapted to the guide rails in the conveyor track 11 to form a guiding constraint. Specifically, the rollers 2243 are embedded in the guide rails in the conveyor track 11. A conveyor sprocket 222 meshes with the inner side of the conveyor chain 221. The conveyor sprocket 222 is connected to the trimming drive device via a drive shaft. The trimming drive device is preferably a trimming servo motor 223. The power output by the trimming servo motor 223 is converted into the cyclic motion of the conveyor chain 221 via the conveyor sprocket 222, driving the push plate assembly 224 to form a continuous thrust output, so that the board passes through the trimming mechanism 4 at a uniform speed. A trimming pressure roller 225 is provided on one side of the trimming mechanism 4 to press the board. The trimming pressure roller 225 is located above the conveyor chain 221 and presses the board being sawn inside the trimming mechanism 4 to prevent the board from shifting or producing poor trimming results due to sawing.

[0051] After prolonged operation, factors such as tension in the conveyor chain 221, wear of the conveyor sprocket 222, or settlement of the installation foundation may cause relative positional deviations in the pusher plate assemblies 224 on both sides. If not corrected in time, this can lead to uneven stress on the plates, causing tilting and affecting trimming accuracy. In this case, the operator can directly input the detected deviation value through the human-machine interface of the control system. The control system then independently controls the trimming servo motor 223 of each pusher plate assembly 224, causing a slight compensating movement in the misaligned assembly. This unilateral adjustment mechanism eliminates the need to stop the machine to adjust the conveyor chain 221; it precisely corrects only the deviation area, ensuring that the pusher plate assemblies 224 on both sides quickly regain positional consistency while avoiding increased costs due to downtime adjustments.

[0052] The edge-binding conveyor mechanism 23 includes an edge-binding conveyor belt 231 and an edge-binding drive device for controlling the rotation of the edge-binding conveyor belt 231. The edge-binding drive device is preferably an edge-binding servo motor 232. Several edge-binding pressure rollers 233 are arranged above the edge-binding conveyor belt 231, and a conveyor drive wheel 234 is arranged above the end of the edge-binding conveyor belt 231. A pressure roller drive device for controlling the movement of the pressure rollers is arranged on the top of the conveyor drive wheel 234. The pressure roller drive device is preferably a pressure roller cylinder 235. The push plate assembly 224 of the trimming conveyor mechanism 22 is driven by the trimming servo motor 223 through the conveyor chain 221, maintaining a preset uniform speed throughout the process. The edge-binding conveyor belt 231 is powered by the edge-binding servo motor 232, and through precise speed control of the edge-binding servo motor, the edge-binding conveyor belt 231 is accelerated from a standstill. When the pusher assembly 224 pushes the rear plate to a distance from the edge-wrapping station, that is, when the front and rear plates reach a certain distance, a detection sensor is set on the conveyor track 11 or the frame near the edge-wrapping mechanism. The detection sensor detects the signal of the rear plate, and the detection signal triggers the control system to control the edge-wrapping conveyor belt 231 to start from a standstill. At this time, the rear plate is driven by the pusher assembly 224 to maintain a constant speed, while the front plate begins to accelerate under the drive of the edge-wrapping conveyor belt 231, forming a situation where the rear plate catches up with the front plate. As the speed of the front plate increases, the distance between the two plates continuously decreases. When the speed of the front plate is the same as that of the rear plate, the distance reaches its shortest. Traditional equipment relies on a pusher trolley to provide power for conveying, which requires simultaneously driving the front and rear plates, resulting in high resistance and limited speed. In contrast, in this device, the pusher assembly 224 is only responsible for conveying the rear plate, while the edge-wrapping conveyor belt 231 independently provides power for the front plate. This significantly reduces the load on the pusher assembly 224, enabling it to increase speed while maintaining stable operation. In conjunction with the edge-wrapping servo motor 232, the movement of the front plate is precisely controlled. Through the dynamic process of the rear plate chasing the front plate, the distance between the front and rear plates is reduced to the optimal distance. This ensures the continuity and precision of the edge-wrapping process, reduces wear and tear on core components, lowers maintenance costs and the risk of downtime, and significantly improves overall production efficiency and stability.

[0053] Above the edge-sealing conveyor belt 231, several edge-sealing pressure rollers 233 are evenly arranged along the conveying direction. These rollers are rigidly connected to the support frame 1 via a dedicated bracket. The bracket height can be finely adjusted according to the thickness of the sheet material to ensure stable and appropriate contact between the bottom of the rollers 233 and the sheet surface, generating constant pressure. The rollers 233 increase friction by pressing the sheet material, preventing slippage during conveying and avoiding distance deviations when two sets of sheets are joined. When the edge-sealing conveyor belt 231 drives the front plate, the constant pressure applied by the rollers ensures a tight fit between the sheet material and the conveyor belt surface, preventing slippage caused by uneven sheet surface, slight conveyor belt vibration, or load changes. If slippage occurs, the actual moving speed of the front plate will deviate from the preset speed, disrupting the precise control of the distance between the two plates during the follow-up process. This may result in excessive spacing or collisions when the two plates are joined, affecting the continuity and precision of the edge-sealing process. The edge-sealing roller 233, through stable friction, ensures that the front panel always moves synchronously with the edge-sealing conveyor belt 231, providing reliable support for controlling the distance between the front and rear panels.

[0054] Inside the edge-sealing conveyor belt 231, there are a first support 2311 and a second support 2312, which work together to provide support and attitude adjustment for the edge-sealing conveyor belt 231. The first support 2311 serves as a fixed support structure, rigidly connected to the support frame 1, ensuring that the front half of the edge-sealing conveyor belt 231 (the side closest to the edge-trimming conveyor mechanism 22) maintains a stable horizontal posture during operation, providing a foundation for precise conveying of the sheet metal during edge-sealing. The second support 2312 adopts a movable design; one end is flexibly hinged to the support frame 1 via a hinge shaft 2314, forming a rotatable fulcrum, while the other end is connected to a lifting drive component, preferably a lifting drive cylinder 2313. The lifting drive cylinder 2313 has the advantages of rapid response and stable thrust. The second support 2312, the lifting drive cylinder 2313, and the hinge shaft 2314 constitute a complete attitude adjustment mechanism.

[0055] After the edge banding of the sheet metal and the cutting of the edge banding strip between adjacent sheets are completed, the control system will instruct the lifting drive cylinder 2313 to operate: when the telescopic end of the lifting drive cylinder 2313 retracts, it will apply a downward pulling force to the free end of the second support 2312, causing the second support 2312 to rotate clockwise around the hinge axis 2314, thereby driving the rear half of the edge banding conveyor belt 231 (the side away from the edge trimming conveyor 22 and closer to the next process) to tilt and descend synchronously, forming a gentle slope transitioning from horizontal to the subsequent conveying station. This tilting design can guide the finished sheet metal to slide smoothly onto the conveyor track 11 by its own weight and the residual force of the conveyor belt, avoiding impact or jamming of the sheet metal due to height difference during process connection.

[0056] A conveyor drive wheel 234 is installed above the end of the edge-sealing conveyor belt 231, and a pressure roller cylinder 235 is connected to the top. The pressure roller cylinder 235 controls the lifting and lowering of the conveyor drive wheel 234. After the edge-sealing and cutting of the board is completed, the board is conveyed to the next station by its own gravity and the residual power of the edge-sealing conveyor belt 231. The control system will synchronously trigger the pressure roller cylinder 235 to drive the conveyor drive wheel 234 to move downward and press the surface of the board. Through the friction between the conveyor drive wheel 234 and the subsequent conveyor belt, a continuous and stable propulsion force is provided for the board, ensuring that the board smoothly and accurately enters the next processing step, further ensuring the continuous operation efficiency of the entire production line.

[0057] A support plate 12 is installed in the middle of the support frame 1. When the width of the board is large, relying solely on the support of the two side conveying mechanisms 2 can easily cause the middle part to sag due to its own weight. Long-term conveying may cause damage such as edge cracking and surface deformation of the board. The support plate 12, by contacting the bottom surface of the middle part of the board, can directly support the weight of the middle part of the board, forming a three-point support structure of "two-side conveying + middle support". This fundamentally avoids the risk of deformation caused by insufficient support for wide boards, and at the same time ensures that the board remains horizontal during the conveying process, providing a basic guarantee for the accuracy of subsequent alignment and trimming processes. Several sets of pulleys 13 are installed at the rear end of the support plate 12. The pulleys 13 are located in the middle area of ​​the alignment conveying mechanism 21. When the board moves forward under the drive of the alignment conveyor belt 211, the middle part of its bottom surface contacts the surface of the pulley 13, which can reduce the wear between the bottom surface of the board and the support plate 12, avoid scratches on the surface of the board, and directly reduce the power load of the alignment conveyor belt 211.

[0058] Alignment mechanism 3 is used to align the conveyed sheet metal in all directions, ensuring it is transported at a preset angle. This prevents edge trimming angle deviations caused by sheet metal tilt, which could result in the final sheet metal failing to meet production standards. Alignment mechanism 3 includes a left-right alignment mechanism and a front-back alignment mechanism. The left-right alignment mechanism includes a left push plate and a right push plate respectively positioned on the left and right sides of the support frame 1. A push plate cylinder is located on one side of the left push plate. When the position sensor 14 detects the sheet metal entering, the push plate cylinder drives the left push plate to move to the right, cooperating with the right push plate to clamp the sheet metal, achieving left-right alignment. The front-back alignment mechanism 3 includes a front-back alignment cylinder mounted on the support frame 1, hinged to it. An alignment push plate is located at the telescopic end of the front-back alignment cylinder. The front-back alignment cylinder controls the alignment push plate to move in an arc. After the sheet metal is aligned left and right, the front-back alignment cylinder extends its piston rod, pushing the front end of the sheet metal to align with a preset baseline, completing the front-back positioning. The sheet metal then passes through the alignment conveyor mechanism 21, ensuring accurate subsequent edge trimming dimensions.

[0059] The trimming mechanism 4 is used to trim the edges or burrs around the board, ensuring accuracy for the subsequent edge-wrapping operation. The trimming mechanism 4 includes a main frame; a flipping frame with its lower edge rotating and positioned in the lower half of the main frame; and a small saw assembly mounted on the flipping frame, including a small saw blade, a rotary drive mechanism one, a small saw blade base, and a lifting drive component. The small saw blade is mounted on the output shaft of the rotary drive mechanism one, which is mounted on the small saw blade base. The lifting drive component controls the rotation of the small saw blade base. The sawing device also includes a large saw assembly, which includes a large saw blade, a rotary drive mechanism two, and a large saw assembly frame. The large saw blade is mounted on the output shaft of the rotary drive mechanism two, which is mounted on the large saw assembly frame. The large saw assembly frame is mounted on the flipping frame.

[0060] The edge-wrapping mechanism 5 is used to wrap the edges of the board. After the board is output from the trimming mechanism 4, the edge-wrapping mechanism 5 automatically feeds the edge-wrapping tape. There are many types of edge-wrapping tape; here, paper tape is selected to match the type of board. The paper tape is attached to the edge of the board. After the edge-wrapping is completed, the excess paper tape is cut off or slit by the cutting component of the edge-wrapping mechanism to ensure that the edge-wrapped edge is neat. During edge-wrapping, edge-wrapping mechanisms 5 are set on both sides of the edge-wrapping conveying mechanism 23. The boards on the edge-wrapping conveying mechanism 23 are conveyed intermittently, one by one according to the rhythm of "run-stop-run". With the conveying rhythm of the boards, the edge-wrapping mechanism 5 can continuously wrap the corresponding side of the board. A certain distance is maintained between adjacent boards on the edge-wrapping conveying mechanism 23. This distance is used to allow the cutting component to cut the edge-wrapping paper tape connecting adjacent boards.

[0061] The working process of this invention is as follows:

[0062] Upstream produced boards (such as gypsum board) enter the inlet of conveyor mechanism 2. Position sensor 14 at the inlet continuously monitors the board's position, size, and conveying status, transmitting signals to the control system. Based on feedback from position sensor 14, the control system determines whether the board meets processing requirements.

[0063] The qualified boards first enter the alignment conveyor mechanism 21. The alignment servo motor 212 drives the alignment conveyor belt 211 to move the boards towards the alignment mechanism 3. At this time, the alignment lifting cylinder 213 is activated, first raising the end of the alignment conveyor belt 211 to provide forward power for the boards. After the boards have completely entered the alignment area, the alignment lifting cylinder 213 drives the end of the conveyor belt to fall, and the power is temporarily interrupted to prevent the boards from moving continuously and affecting the positioning.

[0064] The left and right alignment mechanism 3 uses a push plate cylinder to drive the left push plate to move to the right, which, together with the fixed right push plate, clamps the plate and achieves left and right alignment. Then, the front and rear alignment mechanism 3 uses a front and rear alignment cylinder to extend the piston rod and push the alignment push plate to make an arc motion, so that the front end of the plate fits with the preset baseline and completes the front and rear positioning.

[0065] After alignment, the alignment lifting cylinder 213 actuates again, driving part or the entire structure of the alignment conveyor belt 211 to rise, making it re-contact the board and providing conveying power. Simultaneously, the trimming servo motor 223 of the trimming conveyor mechanism 22 starts, driving the conveyor sprocket 222 to rotate, which in turn causes the conveyor chain 221 to move the pusher assembly 224. The pusher plate 2242 of the pusher assembly 224 then contacts the rear end of the board. Under the combined action of the alignment conveyor belt 211 and the pusher assembly 224, the board accelerates into the trimming station. The rollers 2243 of the pusher assembly 224 move within the guide rails of the conveyor track 11, ensuring conveying stability. Under the combined action of the alignment conveyor belt 211 and the pusher assembly 224, the board is pushed into the trimming mechanism 4 at a uniform speed. After entering the trimming station, the trimming pressure roller 225 on one side of the trimming mechanism 4 presses the board firmly, preventing it from shifting due to vibration or force during the trimming process. The tilting frame of the trimming mechanism 4 is adjusted to make the small saw assembly and the large saw assembly fit the size of the board. The lifting drive controls the rotation of the base of the small saw blade, which, together with the first rotary drive mechanism, drives the small saw blade to rotate, and performs fine trimming of the burrs and irregular parts of the board edge. At the same time, the second rotary drive mechanism of the large saw assembly drives the large saw blade to complete the precise trimming of the overall edge of the board, ensuring that the board size meets the standard.

[0066] If the left and right push plate assemblies 224 deviate from their normal motion after long-term operation, the control system can receive the deviation signal and adjust the speed of the single-sided trimming servo motor 223 independently to make the offset push plate assembly 224 produce a slight compensating motion. Synchronization can be restored without stopping the machine, thus ensuring trimming accuracy.

[0067] When the pusher assembly 224 pushes the trimmed sheet material to a certain distance from the edge-sealing conveyor 23, the control system detects a signal and instructs the edge-sealing servo motor 232 of the edge-sealing conveyor 23 to start, driving the edge-sealing conveyor belt 231 to operate. At this time, the pusher assembly 224 continues to push the sheet material towards the edge-sealing conveyor 23. After the sheet material partially enters the edge-sealing conveyor belt 231, the pusher assembly 224 separates from the sheet material, and the sheet material is transported separately by the edge-sealing conveyor belt 231.

[0068] After the board enters the edge-wrapping station, the edge-wrapping mechanism 5 starts and automatically conveys the edge-wrapping tape (such as paper tape) to adhere the edge-wrapping tape to the edge of the board. At the same time, the edge-wrapping pressure roller 233 above the edge-wrapping conveyor belt 231 presses the board tightly. The edge-wrapping pressure roller 233 increases the friction by pressing the board tightly to prevent slippage during conveying and avoid deviation in distance when the two sets of boards are joined.

[0069] When a portion of the board is finished with edge binding, the edge binding conveyor 23 stops operating; when the next set of boards is conveyed to a certain distance from the edge binding conveyor 23, the edge binding conveyor 23 restarts, and the cutting component of the edge binding mechanism 5 cuts the edge binding strip connecting adjacent boards to ensure neat edge binding. After the edge banding tape is cut off, the control system commands the lifting drive cylinder 2313 inside the edge banding conveyor belt 231 to operate. Since one end of the second bracket 2312 is hinged to the support frame 1, its other end is lowered by the lifting drive cylinder 2313, causing the second bracket 2312 to rotate around the hinge point, thereby causing the rear half of the edge banding conveyor belt 231 to tilt and descend, and the edge-banded board falls down. At this time, the rear half of the board is on the conveyor track 11, and the front half is on the rear conveyor belt (another device besides the sawing and sealing machine). The pressure roller cylinder 235 at the top of the end of the edge banding conveyor mechanism 23 drives the conveyor drive wheel 234 to descend. The friction between the conveyor drive wheel 234 and the board provides auxiliary power for the board, increases the friction between the conveyor belt behind the sawing and sealing machine and the board, and ensures that the board is quickly sent away by the rear conveyor and enters the next station.
