Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a sheet metal processing production line and processing technology. 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, water resistance, heat insulation, and durability, and have broad application prospects in areas such as interior and exterior decorative moldings. Traditional production methods for board materials (especially foamed ceramic panels) decorative moldings typically employ processes such as "first making thick slabs, then cutting them into shapes" or "segmented production, then hand-assembling." These traditional methods have several bottlenecks:

[0003] 1. Low production efficiency, low board utilization, and high breakage rate: Each process (cutting, flipping, transferring, and grinding) relies heavily on manual labor or semi-automated equipment. The connection between processes is not smooth, the production pace is slow, and the capacity is limited. When cutting large boards into narrow strips, especially when the strips need to be flipped and stood upright for subsequent processing, improper manual operation often causes the edges and corners of the strips to be bumped and broken, resulting in material waste.

[0004] 2. Foamed thick slabs are not easy to form: Traditional foaming processes produce thicker original blanks (such as those with a thickness > 16cm), which increases the difficulty of foaming and may also cause defects such as deformation and cracking in the blanks during the foaming process.

[0005] 3. Insufficient automation and continuity: The lack of a continuous production line that can integrate processes such as blank taking, longitudinal and transverse cutting, automatic spatial orientation conversion, slitting and separation, and fine grinding restricts the large-scale and modern development of the industry. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a sheet metal processing line and process that enables automated, continuous, and high-precision production of sheet metal strips, particularly enabling the production of high-height products from thin sheet metal blanks. Through a unique multi-segment conveying assembly and a rotating transplanter, the requirements for the original sheet metal blank thickness are reduced, making production easier.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a sheet metal processing production line, comprising, in sequence, a plate loading machine for absorbing sheet metal blanks, a longitudinal cutting machine for cutting sheet metal blanks into rectangular strips, a transfer machine for flipping and transferring the rectangular strips, a beveling machine for beveling the rectangular strips into two triangular strips, a diverting conveyor for separately conveying the two triangular strips, and a line grinding machine for grinding the triangular strips.

[0008] Furthermore, the loading machine is mounted above the roller conveyor assembly via a gantry frame; the loading machine includes a fixed frame, a hinge unit, and a suction plate unit. The fixed frame is mounted on the movable crossbeam of the gantry frame, and one end of the hinge unit is fixedly connected to the bottom of the fixed frame, while the other end is fixedly connected to the suction plate unit.

[0009] Furthermore, the slitting machine is mounted above the multi-segment conveying assembly via a gantry frame; the multi-segment conveying assembly includes a conveyor frame, a drive shaft, a first driven shaft, a second driven shaft, a third driven shaft, and a drive motor for driving the drive shaft to rotate. The drive motor and the drive shaft are mounted on the conveyor frame. The first driven shaft is connected to the drive shaft via a first conveyor belt, the second driven shaft is connected to the drive shaft via a second conveyor belt, and the third driven shaft is connected to the drive shaft via a third conveyor belt. The first, second, and third conveyor belts are spaced apart, a first gap is formed between the first and second driven shafts, and a second gap is formed between the third and second driven shafts.

[0010] Furthermore, the transplanter includes a flipping component that flips the rectangular strips by 90° so that the long side of the end face of the rectangular strips is distributed to the left and right, and a transfer component that receives and transfers the strips.

[0011] Furthermore, the flipping assembly includes a first rotating rod, a second rotating rod, a rotating shaft, and a forward and reverse rotation motor; the first end of the first rotating rod extends to a first gap, the first end of the second rotating rod extends to a second gap, and the second ends of both the first and second rotating rods are fixedly connected to the rotating shaft and can rotate forward or reverse simultaneously under the drive of the forward and reverse rotation motor.

[0012] Furthermore, the side of the first rotating rod away from the second rotating rod is provided with a first abutting component for abutting the strip during cutting, and the side of the second rotating rod away from the first rotating rod is provided with a second abutting component for abutting the strip during cutting.

[0013] Furthermore, the transfer assembly includes a transfer frame and multiple transfer rollers arranged side by side; one end of the transfer roller is mounted on the transfer frame and the other end is positioned towards the flipping assembly; 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, and the sprockets of the multiple transfer rollers are connected together by a chain to rotate synchronously.

[0014] Furthermore, the oblique cutting machine includes an oblique cutting conveying assembly and an oblique cutting assembly, wherein the oblique cutting conveying assembly is provided with a guide rail with a limiting plate.

[0015] Furthermore, the diversion conveyor sequentially includes a first diversion mechanism that separates two triangular strips and a second diversion mechanism that separately conveys the two triangular strips; the first diversion mechanism includes a first diversion conveying assembly and a blower disposed above the first diversion conveying assembly; the first diversion conveying assembly includes a diversion bracket, multiple rotating rollers arranged side by side on the diversion bracket, and multiple buffer rods disposed on both sides of the diversion bracket, with elastic buffer heads at the ends of the buffer rods; the second diversion mechanism includes a second diversion conveying assembly and multiple guide plate assemblies sequentially mounted on the second diversion conveying assembly; the guide plate assembly includes a first vertical rod, a horizontal rod, and a second vertical rod; a hanging member is disposed in the middle of the horizontal rod, and a guide plate is disposed at the bottom end of the hanging member; the guide plates of the multiple guide plate assemblies are arranged in a trumpet shape.

[0016] On the other hand, a strip processing technology includes the following steps:

[0017] S1: The loading machine picks up the slab and feeds it into the roller conveyor assembly, which then conveys it to the multi-stage conveyor assembly. S2: The fine-tuning screws of the first and second abutting assemblies rise and press against the front end of the slab. The cutting unit of the slitting machine descends and cuts the slab into rectangular strips along its width. At this point, the two long sides of the rectangular strips are vertically distributed, and the two short sides are horizontally distributed. S3: The fine-tuning screws of the first and second abutting assemblies descend, and the forward and reverse rotation motors of the flipping assembly control the two rotating rods to rotate forward. The two rotating rods lift the rectangular strips from the bottom and flip them 90° onto the transfer rollers of the transfer assembly. At this point, the two long sides of the rectangular strips are horizontally distributed. S4: The transfer component sends the rectangular strip to the oblique cutting conveyor component, which obliquely cuts the rectangular strip into two triangular strips with triangular end faces along the length of the rectangular strip; S5: The oblique cutting conveyor component conveys the two triangular strips, which are still in an up-and-down attached state, to the first diversion conveyor component of the first diversion mechanism, and controls the blower to blow air downwards to separate the two triangular strips relative to each other; S6: The two triangular strips continue to move forward to the second diversion conveyor component of the second diversion mechanism, and the guide plate component separates the two triangular strips and sends them into the line grinding machine; S7: The line grinding machine grinds the triangular strips into finished strips of the required shape.

[0018] 1. The sheet metal processing production line of this invention has the following beneficial effects: Through the coordinated operation of the sheet metal feeding machine, sheet metal loading machine, slitting machine, transplanting machine, beveling machine, diverting conveyor, and line grinding machine, the entire process of "sheet metal blank - rectangular sheet metal - triangular sheet metal - separation - fine grinding of finished product" is automated and continuous. Its overall technical effect is significant, realizing the production of high-height products from thin sheet metal blanks. Through the unique flipping design of the transplanting machine, the requirements for the thickness of the original sheet metal blank are reduced, making production easier. Automation replaces manual labor, and the processes are seamlessly connected, eliminating the waiting and handling time in the traditional mode. It can achieve 24-hour continuous operation, thereby greatly improving production efficiency and capacity. Furthermore, through mechanical positioning, synchronous conveying, precise cutting and grinding, the dimensional accuracy and quality of the finished product are ensured.

[0019] 2. The processing technology of this invention realizes the large-scale, standardized, and automated processing of slabs into strips: the steps from S1 to S7 are clear and the parameters are controllable, which simplifies production management; the steps are closely linked, such as the cooperation between the supporting component and the slitting machine in S2, the connection between flipping and transfer in S3, and the separation of airflow and mechanical flow in S5-S6, which demonstrates a high degree of equipment synergy; in addition, by adjusting the slitting width, bevel cutting angle, grinding and shaping, the process can flexibly produce strips of different specifications and cross-sectional shapes, which has strong market adaptability.

[0044] 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.

[0045] 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.

[0046] Please see the appendix Figure 2-12 The present invention provides a processing line 200 for slab strips 104, which includes, in sequence, a board feeder 1 for placing slab blanks 101, a board loading machine 2 for picking up slab blanks 101, a longitudinal cutting machine 3 for cutting slab blanks into rectangular slab strips 102, a transplanting machine 4 for flipping and transferring the rectangular slab strips 102, a beveling machine 5 for beveling the rectangular slab strips 102 into two triangular slab strips 103, a diverting conveyor 6 for separately conveying the two triangular slab strips 103, and a line grinding machine 7 for grinding the triangular slab 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 transplanting machine 4 performs key spatial posture conversion (90° rotation) 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.

[0047] 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.

[0048] As attached Figure 3 As 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.

[0049] 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.

[0050] As attached Figure 4 As 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.

[0051] 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 it to cut in during cutting and avoid obstacles when not 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.

[0052] As attached Figure 6-7As 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, a third driven shaft 95, and a drive motor for driving the drive shaft 92 to rotate. The drive shaft 92 is located at the front end of the conveyor frame 91, and 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 conveying 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 transplanter 4 to rise from below, lifting and flipping the slab, making it a key structure for coordinated operation.

[0053] As attached Figure 6 As shown, the transplanter 4 includes a flipping component 41 that flips the rectangular slats 102 by 90° so that the long side of the end face of the rectangular slats 102 is distributed to the left and right, and a transfer component 42 that receives and transfers the slats. The transplanter 4 integrates the flipping and transfer actions into one unit, which not only completes the key posture transformation of the rectangular slats 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 slats 102 from the current workstation and transports them to the next process, greatly simplifying the process and improving space utilization and production efficiency.

[0054] 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 synchronous, fixed-angle (90° forward rotation or reverse rotation to return to position) rotation power for the two rotating rods. The first end of the first rotating rod 411 extends to the first gap 96, and the first end of the second rotating rod 412 extends to the second gap 97. The second ends of both the first rotating rod 411 and the second rotating rod 412 are fixedly connected to the rotating shaft 413 and can rotate forward or reverse simultaneously under the drive of the forward / reverse rotation motor 414. When placed horizontally, the top surfaces of the first rotating rod 411 and the second rotating rod 412 are not higher than the first conveyor belt, the second conveyor belt, and the third conveyor belt, 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.

[0055] 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.

[0056] 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 strips 102 from falling off.

[0057] As attached Figure 11 As 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.

[0058] As attached Figure 12 As 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] The sheet metal processing line 200 of this invention, through the coordinated operation of the sheet metal feeder 1, sheet metal loading machine 2, slitting machine 3, transplanting machine 4, beveling machine 5, diverting conveyor 6, and line grinding machine 7, achieves fully automated and continuous production of sheet metal strips 104 from "slab blank - rectangular strip - triangular strip → separation → fine grinding of finished product". Its overall technical effects are significant: it enables the production of high-height products from thin sheet blanks; the unique flipping design of the transplanting machine 4 reduces the requirement for the original sheet blank thickness, making production easier; automation replaces manual labor, with seamless connection between each process, eliminating waiting and handling time in the traditional mode, enabling 24-hour continuous operation, thereby 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.

[0063] As attached Figure 1-12 As shown, the present invention also provides a processing method for processing a slab 101 into a strip 104, comprising the following steps:

[0064] S1: The plate feeder 2 picks up the slab 101 and feeds it into the roller conveyor assembly 8. The roller conveyor assembly 8 then conveys the slab 101 into the multi-stage conveyor assembly 9.

[0065] S2: The fine-tuning screws of the first abutting component 43 and the second abutting component 44 rise and abut the front end of the slab 101; the cutting unit 33 of the longitudinal cutting 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.

[0066] S3: The fine-tuning screws of the first abutting component 43 and the second abutting component 44 descend, and the forward and reverse rotation motor 414 of the flipping component 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 component 42. At this time, the two long sides (L1 and L2) of the end face of the rectangular strip 102 are distributed left and right, and the two short sides (S1 and S2) are distributed up and down.

[0067] S4: 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.

[0068] S5: The oblique conveying assembly 51 conveys the two triangular strips 103, which are still in an up-and-down attached state, to the first diversion conveying assembly 611 of the first diversion mechanism 61, and controls the blower 612 to blow air downwards to separate the two triangular strips 103 relative to each other.

[0069] S6: The two triangular strips 103 continue to move forward into the second diversion conveying assembly 621 of the second diversion mechanism 62, and the guide plate assembly 622 separates the two triangular strips 103 and feeds them into the line mill 7.

[0070] S7: The line grinding machine 7 grinds the triangular strip 103 into the finished strip 104 of the required shape.

[0071] The processing technology of this invention realizes the large-scale, standardized and automated processing of slab 101 into strip 104: the steps from S1 to S7 are clear and the parameters are controllable, which simplifies production management; the steps are closely linked, such as the cooperation between the supporting component and the slitting machine 3 in S2, the connection between flipping and transfer in S3, and the separation of airflow and mechanical flow in S5-S6, which demonstrates a high degree of equipment synergy; in addition, by adjusting the slitting width, bevel angle, grinding and shaping, the process can flexibly produce strips 104 of different specifications and cross-sectional shapes, which has strong market adaptability.
