Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a sheet metal processing production line turnover machine and a sheet metal turnover process. Background Technology

[0002] Board materials, as a fundamental material in building decoration and structural applications, come in a wide variety, including wood-based panels, metal panels, composite panels, and ceramic panels. Among them, foamed ceramic panels, as a new type of green building material, possess excellent properties such as lightweight, fire resistance, heat insulation, and durability, and are widely used in building decoration. In the process of processing foamed ceramic panels into decorative moldings, it is often necessary to flip the cut rectangular strips, changing them from a flat to an upright position, in order to perform subsequent beveling, sanding, and other processing. Traditional strip flipping often relies on manual labor or simple machinery, which presents the following problems:

[0003] 1. Slats are easily damaged: During the flipping process, the edges and corners of the slats are easily bumped and broken, resulting in material waste and a decrease in yield.

[0004] 2. Poor positioning accuracy: Manual flipping makes it difficult to ensure that the slats are in the same position, which affects the alignment of subsequent processing and the accuracy of the finished product;

[0005] 3. Low level of automation: Traditional flipping methods are difficult to automate with upstream and downstream processes, which restricts the overall efficiency and integration level of the production line. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a flipping machine for sheet metal processing production lines. The flipping machine integrates the two actions of flipping and transferring into one, completing the key posture transformation of rectangular strips from "lying flat" (long side horizontal) to "standing upright" (long side vertical), realizing automatic, stable, and precise flipping of the strips, thereby improving the quality of strip production.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a turning machine for a sheet metal processing production line, comprising: a multi-segment conveying assembly, including at least three spaced conveyor belts with gaps between adjacent conveyor belts; a turning assembly, including at least two rotating rods, one end of each rotating rod extending into the gap, and the other end fixedly connected to a rotating shaft, the rotating shaft being driven by a forward and reverse rotation motor; and a transfer assembly, located at the output end of the multi-segment conveying assembly, including a transfer frame and multiple transfer rollers arranged side by side, for receiving the sheet metal strips turned by the turning assembly.

[0008] Furthermore, the multi-segment conveying assembly includes a conveyor frame, a drive shaft, a first driven shaft, a second driven shaft, and a third driven shaft; the drive shaft is driven by a drive motor and is connected to the first driven shaft, the second driven shaft, and the third driven shaft via the first conveyor belt, the second conveyor belt, and the third conveyor belt, respectively; a first gap is formed between the first conveyor belt and the second conveyor belt, and a second gap is formed between the second conveyor belt and the third conveyor belt.

[0009] Furthermore, the flipping assembly includes a first rotating rod and a second rotating rod; the first end of the first rotating rod extends into a first gap, and the first end of the second rotating rod extends into a second gap; the second ends of both the first rotating rod and the second rotating rod are fixed on the same rotating shaft and are driven to rotate synchronously by a forward and reverse rotation motor.

[0010] Furthermore, the top surfaces of the first and second rotating rods are not higher than the conveying surface of the conveyor belt when not in operation.

[0011] Furthermore, a first abutting component is provided on the side of the first rotating rod away from the second rotating rod, and a second abutting component is provided on the side of the second rotating rod away from the first rotating rod.

[0012] Furthermore, the first abutting component includes a first fine-tuning screw, a first screw seat for mounting the first fine-tuning screw, and a first lifting motor for driving the first screw seat to rise and fall; the second abutting component includes a second fine-tuning screw, a second screw seat for mounting the second fine-tuning screw, and a second lifting motor for driving the second screw seat to rise and fall.

[0013] Furthermore, the transfer frame includes a first frame and a second frame arranged side by side. The end of the transfer roller away from the flipping assembly is mounted on the top of the first frame via a first bearing and on the top of the second frame via a second bearing. A sprocket is fixed between the first bearing and the second bearing of the transfer roller. The sprockets of multiple transfer rollers are connected together by a chain to rotate synchronously.

[0014] Furthermore, the transfer frame roller is a polyurethane roller.

[0015] On the other hand, the slat flipping process of the flipping machine includes the following steps:

[0016] S1: The slats are conveyed to the preset position via a multi-segment conveyor assembly;

[0017] S2: Control the rotating rod of the flipping component to rise from the gap in the conveyor belt and lift the slats;

[0018] S3: The forward and reverse rotation motor drives the rotating rod to rotate 90°, flipping the slats and placing them on the transfer assembly;

[0019] S4: The transfer assembly conveys the flipped slats to the next process.

[0020] Furthermore, the strip is a rectangular strip made of foamed material, and after being flipped, its long side at the end face changes from horizontal to vertical.

[0021] The flipping machine and strip flipping process of the sheet metal processing production line of the present invention have the following beneficial effects:

[0022] 1. The flipping machine integrates flipping and transfer operations into one unit. It not only completes the crucial posture transformation of rectangular strips from "lying flat" (long side horizontal) to "standing upright" (long side vertical), significantly increasing the effective height for subsequent processing, but also removes the flipped rectangular strips from the current workstation and transports them to the next process, greatly simplifying the process and improving space utilization and production efficiency. The multi-segment conveying assembly forms the physical space (first gap, second gap) for the flipping mechanism (rotating rod). It can stably convey the blank / strip during cutting and provide execution space for the subsequent flipping process. It is a key transitional device connecting the longitudinal cutting and flipping processes, achieving seamless connection between processes. The flipping assembly utilizes the two gaps formed by the multi-segment conveying assembly, allowing the rotating rod to be hidden under the conveying surface when not in operation; during operation, it rises, using the bottom of the strip as a fulcrum, and achieves a smooth 90° flip using two-point support. The structure is simple, the action is precise, and the impact on the rectangular strips is minimal. The transfer assembly forms a transition platform that receives the flipped rectangular strips and continues to transport them forward. Its structure is simple and reliable. Through multiple synchronously rotating transfer rollers, it can not only smoothly receive the rectangular strips, but also transport them to the slant cutting machine in the correct direction, ensuring the smooth connection of the processes.

[0023] 2. The slat flipping process uses a multi-segment conveying component, flipping component, and transfer component to achieve automatic 90° flipping and transfer of slats, replacing manual operation and greatly improving flipping efficiency and safety; the flipping process is stable and precise, effectively avoiding damage to the edges and corners of rectangular slats and improving the yield; the overall structure is seamlessly connected with the preceding and following processes, supports continuous and automated production, and is suitable for reliable flipping of slats of different specifications.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see the appendix Figure 1 The diagram illustrates the transformation of a slab into strips. The slab 101 has dimensions of 240cm*120cm*12cm. After longitudinal cutting, a rectangular strip 102 with dimensions of 16cm*120cm*12cm is obtained. After beveling, a triangular strip 103 with three sides of 16cm*12cm*20cm is obtained. Finally, the 20cm beveled edge is ground and processed into a strip 104 with a specific shape. Preferably, in this invention, the slab 101 is a foamed ceramic slab 101. Example 1

[0050] As attached Figure 6-10As shown, this embodiment provides a flipping machine 4 for a sheet metal processing production line. The flipping machine 4 includes a multi-segment conveying assembly 9, a flipping assembly 41 that flips a rectangular strip 102 by 90° so that the long side of the end face of the rectangular strip 102 faces upward, and a transfer assembly 42 that receives and transfers the strip. The multi-segment conveying assembly 9 is located below the slitting machine 3 and includes at least three conveyor belts spaced apart, with gaps formed between adjacent conveyor belts. The flipping assembly 41 includes at least two rotating rods, one end of each rotating rod extending into the gap, and the other end fixedly connected to a rotating main shaft, which is driven by a forward and reverse rotation motor. The transfer assembly 42 is located at the output end of the multi-segment conveying assembly 9 and includes a transfer frame 421 and multiple transfer rollers 422 arranged side by side, for receiving the rectangular strip 102 flipped by the flipping assembly 41. The flipping machine 4 integrates the flipping and transfer actions into one unit. It not only completes the key posture transformation of the rectangular strip 102 from "lying flat" (long side horizontal) to "standing upright" (long side vertical), thus significantly increasing the effective height during subsequent processing, but also removes the flipped rectangular strip 102 from the current workstation and transports it to the next process, greatly simplifying the process and improving space utilization and production efficiency.

[0051] As attached Figure 7 As shown, the multi-segment conveying assembly 9 includes a conveyor frame 91, a drive shaft 92, a first driven shaft 93, a second driven shaft 94, and a third driven shaft 95. The drive shaft 92 is located at the front end of the conveyor frame 91 and is driven by a drive motor. The first driven shaft 93, the second driven shaft 94, and the third driven shaft 95 are located at the rear end of the conveyor frame 91. The drive motor and the drive shaft 92 are mounted on the conveyor frame 91. The first driven shaft 93 is connected to the drive shaft 92 via a first conveyor belt, the second driven shaft 94 is connected to the drive shaft 92 via a second conveyor belt, and the third driven shaft 95 is connected to the drive shaft 92 via a third conveyor belt. The first conveyor belt, the second conveyor belt, and the third conveyor belt are spaced apart to form a first gap 96 between the first driven shaft 93 and the second driven shaft 94, and a second gap 97 between the third driven shaft 95 and the second driven shaft 94. The core design of the multi-segment conveyor assembly 9 lies in the physical space (first gap 96, second gap 97) formed for the interleaving and flipping mechanism (rotating rod). It not only stably conveys the slab / strip during cutting but also provides execution space for the subsequent flipping process. It is a crucial transitional device connecting the longitudinal cutting and flipping processes, achieving seamless integration between them. The conveyor frame 91, drive shaft 92, three driven shafts, and three conveyor belts constitute three independent narrow-width conveyor belt structures, jointly supporting and conveying the slab. The first gap 96 and second gap 97 reserve space, allowing the flipping assembly 41 (rotating rod) of the flipping machine 4 to rise from below, lifting and flipping the slab, which is a key structure for coordinated operation.

[0052] As attached Figure 8As shown, the flipping assembly 41 includes a first rotating rod 411, a second rotating rod 412, a rotating shaft 413, and a forward / reverse rotation motor 414. The first rotating rod 411 and the second rotating rod 412 serve as actuators. The rotating shaft 413 and the forward / reverse rotation motor 414 provide power for the two rotating rods to rotate synchronously at a fixed angle (90° forward rotation or reverse rotation to return to position). The first end of the first rotating rod 411 extends into the first gap 96, and the first end of the second rotating rod 412 extends into the second gap 97. The second ends of both the first rotating rod 411 and the second rotating rod 412 are fixed on the same rotating shaft 413 and are driven to rotate synchronously by the forward / reverse rotation motor 414. The top surfaces of the first rotating rod 411 and the second rotating rod 412 are not higher than the conveying surface of the conveyor belt when not in operation, thus avoiding interference with the conveying of the rectangular slats 102. The flipping assembly 41 is an ingenious, reliable, and non-interfering flipping structure. Utilizing the two gaps formed by the multi-segment conveyor assembly 9, the rotating rod can be hidden under the conveyor surface when not in operation; during operation, it rises and uses the bottom of the slat as a fulcrum to achieve a smooth 90° flip using two-point support. The structure is simple, the action is precise, and the impact on the rectangular slat 102 is minimal. To avoid cutting the conveyor belt, a connection with a thickness of less than 0.5mm is left between the bottom of the longitudinally cut slab 101 and the rectangular slat 102. Due to the material characteristics of foamed ceramic, this extremely thin connection will be torn off by the flipping action.

[0053] As attached Figure 8-9 As shown, the first rotating rod 411 has a first abutting component 43 for abutting the slab during cutting on its side away from the second rotating rod 412, and the second rotating rod 412 has a second abutting component 44 for abutting the slab during cutting on its side away from the first rotating rod 411. The first abutting component 43 includes a first fine-tuning screw 431, a first screw seat 432 for mounting the first fine-tuning screw 431, and a first lifting motor 433 for driving the first screw seat 432 to rise and fall. The second abutting component 44 includes a second fine-tuning screw, a second screw seat for mounting the second fine-tuning screw, and a second lifting motor for driving the second screw seat to rise and fall. The first abutting component 43 and the second abutting component 44 play a positioning role in the longitudinal cutting process. Before cutting, the fine-tuning screw rises and abuts the front end of the slab, counteracting the conveying power at the rear end, ensuring the absolute stillness of the slab at the moment of cutting, thereby ensuring the accuracy of the cutting size and the quality of the cut. The fine-tuning design of the fine-tuning screw can adapt to the positioning requirements of rectangular slabs 102 of different specifications. The lifting motor drives the screw seat and the fine-tuning screw to move vertically, thus achieving the action of pressing and releasing.

[0054] As attached Figure 10As shown, the transfer assembly 42 includes a transfer frame 421 and multiple transfer rollers 422 arranged side by side. One end of the transfer roller 422 is mounted on the transfer frame 421, and the other end faces the flipping assembly 41. The transfer frame 421 includes a first frame 4211 and a second frame 4212 arranged side by side. The end of the transfer roller 422 away from the flipping assembly 41 is mounted on the top of the first frame 4211 via a first bearing 423 and on the top of the second frame 4212 via a second bearing 424. A sprocket is fixed between the first bearing 423 and the second bearing 424 of the transfer roller 422. The sprockets of the multiple transfer rollers 422 are connected together by a chain and can be driven by a motor to rotate synchronously. The transfer assembly 42 constitutes a transition platform that receives the flipped rectangular strip 102 and continues to transport it forward. Its structure is simple and reliable. Through multiple synchronously rotating transfer rollers 422, it can not only smoothly receive the rectangular strip 102, but also transport it to the slitting machine 5 in the correct direction, ensuring the smooth connection of the processes. The second frame 4212 is provided with a baffle 45 to prevent the rectangular slats 102 from falling. Preferably, the transfer roller 422 is a polyurethane roller, which is relatively soft and can effectively avoid scratching the surface of the rectangular slats 102.

[0055] The slat flipping process of the flipping machine 4 in this embodiment includes the following steps:

[0056] S1: The slats are conveyed to the preset position via the multi-segment conveyor assembly 9;

[0057] S2: The rotating rod of the control tilting assembly 41 rises from the gap in the conveyor belt to lift the slats;

[0058] S3: The forward and reverse rotation motor 414 drives the rotating rod to rotate 90°, flipping the strip and placing it on the transfer assembly 42; after flipping, the long side of the strip end face changes from horizontal to vertical;

[0059] S4: Transfer assembly 42 transports the flipped slats to the next process.

[0060] This slat flipping process utilizes a multi-segment conveying assembly 9, a flipping assembly 41, and a transfer assembly 42 to achieve automatic 90° flipping and transfer of slats, replacing manual operation and significantly improving flipping efficiency and safety. The flipping process is stable and precise, effectively preventing damage to the edges and corners of rectangular slats 102 and improving the yield rate. The overall structure is seamlessly connected with the preceding and following processes, supporting continuous and automated production, and is suitable for reliable flipping of slats of different specifications. Example 2

[0061] Please see the appendix Figure 1-12This embodiment provides a sheet metal processing production line 200, which includes, in sequence, a sheet metal feeding machine 1 for placing sheet metal blanks 101, a sheet metal loading machine 2 for picking up sheet metal blanks 101, a longitudinal cutting machine 3 for cutting sheet metal blanks into rectangular strips 102, a flipping machine 4 for flipping and transferring the rectangular strips 102 (for specific structure, refer to Embodiment 1), a beveling machine 5 for beveling the rectangular strips 102 into two triangular strips 103, a diverting conveyor 6 for separately conveying the two triangular strips 103, and a line grinding machine 7 for grinding the triangular strips 103. The feeding machine 1 stores the slab blanks 101 in an orderly manner; the loading machine 2 realizes automated blank picking, replacing manual handling, improving efficiency and ensuring operational safety, and ensuring that the slab blanks enter the next process in the correct posture; the slitting machine 3 is responsible for cutting the large panel blanks into rectangular strips 102 of preset width along the width direction, which is the basic step for subsequent shaping processing; the flipping machine 4 performs key spatial posture conversion (flipping 90°) and station transfer, providing the correct strip orientation for the subsequent beveling process; the beveling machine 5 divides the upright rectangular strips 102 into two triangular strips 103 along the diagonal, which is the key forming step for transforming the blanks into linear products; the diverting conveyor 6 can solve the problem of the two triangular strips 103 naturally adhering after beveling, separating them smoothly and without damage and guiding them to different paths, preparing for parallel grinding; the line grinding machine 7 performs fine processing on the beveled edges and surface of the triangular strips 103, grinding out the required decorative shape (such as wave shape), and finally forming the product.

[0062] This invention constructs a highly integrated and automated continuous processing line 200 for processing slabs 101 into strips 104, including orderly serial processes of blank taking, longitudinal cutting, flipping, oblique cutting, separation, and grinding. It solves the problems of traditional thick slabs being difficult to foam, low efficiency of segmented operations, high damage rate during transportation, and difficulty in ensuring processing accuracy, and realizes large-scale, standardized, and automated production of strips 104.

[0063] As attached Figure 3As shown, the loading machine 2 is mounted above the roller conveyor assembly 8 via a gantry frame. The loading machine 2 includes a fixed frame 21, a hinge unit 22, and a suction unit 23. The fixed frame 21 is mounted on the movable crossbeam of the gantry frame. One end of the hinge unit 22 is fixedly connected to the bottom of the fixed frame 21, and the other end is fixedly connected to the suction unit 23. The loading machine 2 achieves a wide range of movement via the gantry frame. Through the rotation of the hinge unit 22, the suction unit 23 can flexibly switch between horizontal suction and vertical placement positions. The movement is precise and the impact is small, effectively preventing the edges and corners of the slab from being damaged by rigid collisions during the loading and unloading process. The fixed frame 21 is an intermediate support connecting the movable crossbeam and the hinge unit 22. Preferably, the number of hinge units 22 in this invention is two. Each hinge unit 22 includes a first hinge plate and a second hinge plate rotatably connected by a pin shaft, forming a mechanical joint whose rotation angle can be precisely controlled. This is the core mechanism for realizing the rotation of the suction plate unit 23. Specifically, the first hinge plate is fixedly connected to the fixed frame 21, and the second hinge plate is fixedly connected to the suction plate unit 23. It also includes a rotation drive motor that drives the pin shaft to rotate, providing precise and controllable power for the rotation of the hinge unit 22, thereby driving the second hinge plate to rotate, so that the suction plate unit 23 rotates between the plate feeder 1 and the roller conveying assembly 8.

[0064] As attached Figure 3 As shown, the suction plate unit 23 includes a transverse connecting strip 231 and multiple longitudinal mounting strips 232. The transverse connecting strip 231 is fixedly connected to the hinge unit 22. The multiple longitudinal mounting strips 232 are arranged side by side and are all fixedly connected perpendicularly to the transverse connecting strip 231. Multiple vacuum suction cups 233 are provided on the side of any longitudinal mounting strip 232 away from the transverse connecting strip 231. The suction plate unit 23, through the grid layout of "transverse connecting strip 231 + multiple longitudinal mounting strips 232", achieves stable and balanced adsorption of large-sized, high-weight slab blanks 101. The multiple vacuum suction cups 233 are evenly distributed, providing sufficient adsorption force and effectively preventing the slab blank from bending or falling off due to uneven force during movement and rotation. The transverse connecting strip 231 serves as the main load-bearing structure and is fixed to the hinge unit 22; the longitudinal mounting strip 232 expands the adsorption area, forming multiple parallel adsorption zones to adapt to the large-area structure of the slab; the vacuum suction cup 233 directly contacts the slab surface, using negative pressure to generate adsorption force, and its flexible contact can adapt to the slight unevenness of the slab surface.

[0065] As attached Figure 4As shown, the roller conveying assembly 8 includes a support frame 81 and multiple roller conveying units 82 that are equidistantly spaced and transversely arranged on the support frame 81. Each roller conveying unit 82 includes a rotating main shaft 821, multiple polyurethane rollers 822 fixedly sleeved on the rotating main shaft 821, and a reduction motor 823 that drives the rotating main shaft 821 to rotate. The two ends of the rotating main shaft 821 are mounted on the support frame 81 through bearing assemblies 824. The multiple polyurethane rollers 822 are equidistantly spaced. The bearing assembly 824 includes a bearing and a bearing seat. The bearing is installed in the bearing seat, and the bearing seat is fixedly installed on the support frame 81. Each rotating main shaft 821 is provided with a sprocket 825, and the sprockets 825 of the multiple rotating main shafts 821 are connected together by a chain to rotate synchronously. The roller conveyor assembly 8 provides a stable, low-damage, and highly synchronized sheet material conveying solution. The rotating spindle 821 and polyurethane roller 822 directly support and drive the slab 101 forward. The polyurethane roller 822 has a relatively soft cylindrical material, which can effectively avoid scratching the surface of the slab 101. The bearing assembly 824 ensures that the rotating spindle 821 rotates flexibly and with low resistance. All rotating spindles 821 are linked through a sprocket and chain structure to ensure that multiple rotating spindles 821 rotate mechanically synchronously, eliminating slab slippage, offset, or twisting caused by speed differences, and laying the foundation for subsequent precise positioning and cutting.

[0066] As attached Figure 5 As shown, the slitting machine 3 is mounted above the multi-section conveying assembly 9 via a gantry frame. The slitting machine 3 includes a mounting base 31, a transverse drive unit 32 for driving the mounting base 31 to move laterally, a cutting unit 33, and a lifting cylinder 34 for driving the cutting unit 33 to rise and fall. The mounting base 31 is located on the crossbeam of the gantry frame. The transverse drive unit 32 and the lifting cylinder 34 are mounted on the mounting base 31. The cutting unit 33 is fixedly mounted on the output end of the lifting cylinder 34. The cutting unit 33 includes a saw blade, a cutting motor for driving the saw blade to cut, and a rotary motor for driving the saw blade to rotate. The slitting machine 3 achieves automatic, precise, and efficient cutting of the slab 101. By controlling the transverse drive unit 32 to feed the saw blade laterally along the width direction of the slab, and by controlling the cutting and lifting of the saw blade by the lifting cylinder 34, combined with the cutting motor and the rotary motor, high-quality straight cutting can be completed, accurately dividing the large slab into rectangular strips 102 of the required width. The lifting cylinder 34 controls the vertical movement of the saw blade, enabling cutting in during cutting and avoidance during non-cutting; the cutting motor drives the saw blade to rotate at high speed for cutting; the rotating motor adjusts the cutting angle of the saw blade.

[0067] As attached Figure 11As shown, the beveling machine 5 includes a beveling conveyor assembly 51 and a beveling assembly 52. ​​The beveling conveyor assembly 51 is equipped with a guide rail 53 for limiting the strips. The beveling conveyor assembly 51 is a belt conveyor assembly. The beveling assembly 52 includes an inclined saw blade and a beveling motor that drives the saw blade to rotate. The front end of the guide rail 53 is provided with an expansion plate 54 inside the guide rail 53 to facilitate the entry of the rectangular strip 102. The beveling machine 5 realizes the function of beveling the rectangular strip 102 at a fixed angle. The beveling conveyor assembly 51 provides stable forward power, and the belt conveyor helps to maintain the stability of the upright strip. The guide rail 53 guides and limits the rectangular strip 102, ensuring that it passes through the saw blade along a precise path and ensuring the accuracy of the diagonal cut. The design of the expansion plate 54 reduces the difficulty of the strip entering the guide rail 53 and improves the smoothness of feeding.

[0068] As attached Figure 12As shown, the diversion conveyor 6 sequentially includes a first diversion mechanism 61 that separates the two triangular strips 103 and a second diversion mechanism 62 that separately conveys the two triangular strips 103. The diversion conveyor 6 provides an efficient and gradual separation scheme for the triangular strips 103. First, the tightly fitted triangular strips 103 are initially separated by air force (first diversion mechanism 61), and then the two are smoothly guided to different conveying paths or subsequent equipment by a gradually changing mechanical guiding device (second diversion mechanism 62). The entire process avoids rigid scraping or hard bending, effectively protecting the edges and cut surfaces of the brittle ceramic strips. The first diversion mechanism 61 includes a first diversion conveying assembly 611 and a blower 612 disposed above the first diversion conveying assembly 611. The first diversion conveying assembly 611 includes a diversion bracket 6111, a plurality of rotating rollers 6112 arranged side by side on the diversion bracket 6111, and a plurality of buffer rods 6113 disposed on both sides of the diversion bracket 6111. The buffer rods 6113 are inclined downward from the side of the diversion bracket 6111 towards the middle of the diversion bracket 6111, and the ends of the buffer rods 6113 are provided with elastic buffer heads 6114. The blower 612 of the first diversion mechanism 61 uses airflow to seep in from the seam to generate a separation force, realizing the initial flexible separation of the two triangular strips 103. The buffer rods 6113 and the elastic buffer heads 6114 can prevent the triangular strips 103 from deviating excessively from or impacting the bracket during the conveying process, playing a protective and limiting role. The second diversion mechanism 62 includes a second diversion conveying assembly 621 and multiple guide plate assemblies 622 sequentially mounted on the second diversion conveying assembly 621. The second diversion conveying assembly 621 is a belt conveyor assembly. The guide plate assembly 622 includes a first vertical rod 6221, a horizontal rod 6222, and a second vertical rod 6223. The first vertical rod 6221 and the second vertical rod 6223 are respectively located on both sides of the second diversion conveying assembly 621. The two ends of the horizontal rod 6222 are connected to the first vertical rod 6221 and the second vertical rod 6223 respectively. A hanging member 6224 is provided in the middle of the horizontal rod 6222, and two guide plates 6225 arranged in a figure-eight shape are provided at the bottom of the hanging member 6224. The guide plates 6225 of the multiple guide plate assemblies 622 are arranged in a trumpet shape. The second diversion mechanism 62 guides the two triangular strips 103 to both sides gradually and smoothly through the trumpet-shaped channel formed by a series of figure-eight guide plates 6225, completing the complete spatial diversion.

[0069] As attached Figure 2 As shown, the line grinding machine 7 is a four-head double-sided line grinding machine 7, which can grind the inclined edges of two triangular strips 103 at the same time. Multiple grinding heads perform different processes such as rough grinding and fine grinding, which improves the grinding efficiency and processing accuracy of the triangular strip 103 shaping surface and ensures the appearance quality of the final product.

[0070] The working principle of the slat processing production line 200 in this embodiment is as follows:

[0071] The loading machine 2 first picks up the slab 101 and feeds it into the roller conveyor assembly 8. The roller conveyor assembly 8 then conveys the slab 101 to the multi-segment conveyor assembly 9. The fine-tuning screws of the first abutting assembly 43 and the second abutting assembly 44 rise and abut the front end of the slab 101. The cutting unit 33 of the slitting machine 3 descends and cuts the slab 101 into rectangular strips 102 along the width direction. At this time, the two long sides (L1 and L2) of the end face of the rectangular strip 102 are distributed vertically, and the two short sides (S1 and S2) are distributed horizontally. The fine-tuning screws of the first abutting assembly 43 and the second abutting assembly 44 descend, and the forward and reverse rotation motor 414 of the flipping assembly 41 controls the two rotating rods to rotate forward. The two rotating rods lift the rectangular strip 102 from the bottom and flip it 90° onto the transfer roller 422 of the transfer assembly 42. At this time, the two long sides (L1 and L2) of the end face of the rectangular strip 102 are distributed vertically, and the two short sides (S1 and S2) are distributed horizontally. The rectangular strips 102 are distributed horizontally (S1 and S2) and vertically (S1 and S2). The transfer component 42 sends the rectangular strip 102 to the oblique cutting conveyor component 51. The oblique cutting component 52 obliquely cuts the rectangular strip 102 into two triangular strips 103 with triangular end faces along the length direction of the rectangular strip 102. The oblique cutting conveyor component 51 conveys the two triangular strips 103, which are still in an up-and-down attached state, to the first diversion conveyor component 611 of the first diversion mechanism 61. The blower 612 is controlled to blow air downwards to separate the two triangular strips 103 relative to each other. The two triangular strips 103 continue to move forward into the second diversion conveyor component 621 of the second diversion mechanism 62. The guide plate component 622 separates the two triangular strips 103 and sends them into the line mill 7. The line mill 7 grinds the triangular strips 103 into finished strips 104 of the required shape.

[0072] The slab processing line 200 in this embodiment achieves fully automated and continuous production of slabs 104 through the coordinated operation of the slab feeder 1, slab loading machine 2, slitting machine 3, turning machine 4, beveling machine 5, diverting conveyor 6, and line grinding machine 7, from "slab blank - rectangular slab - triangular slab → separation → fine grinding of finished product". Its overall technical effects are significant: it enables the production of high-height products from thin slab blanks; the unique turning machine 4's turning design reduces the requirement for the original slab thickness, making production easier; automation replaces manual labor, with seamless connections between processes, eliminating waiting and handling time in traditional models, enabling 24-hour continuous operation, thus greatly improving production efficiency and capacity; and through mechanical positioning, synchronous conveying, precise cutting, and grinding, it ensures the dimensional accuracy and quality of the finished product.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
