Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and in particular to a plate cutting machine. Background Art

[0002] In the field of modern industrial manufacturing, laser cutting technology has been widely used. Laser cutting machines can accurately cut various materials to meet diverse production needs. However, after the laser cutting process is completed, the material unloading process becomes a significant problem.

[0003] In some current technical solutions, a gripper is used to grab the cut material for unloading. Although this method has achieved automation to a certain extent, it has obvious limitations. The gripper's grabbing efficiency is limited by its own mechanical structure and movement speed, and cannot meet the production requirements of unloading a large number of cut materials at the same time. When a large amount of cut materials needs to be processed, the gripper's grabbing speed is far behind the cutting speed, resulting in a bottleneck in the entire production process.

[0004] Manual unloading is a traditional unloading method. Several operators manually remove the cut materials from the cutting table. This method has serious inefficiency problems. The operating speed and endurance of people are limited. When facing a large number of cut materials, it takes a lot of time and manpower. Moreover, manual operation is prone to fatigue and mistakes, which may damage the cut materials and affect product quality.

[0005] Whether it is grabbing with a gripper or manual unloading, there is the problem of difficulty in separating waste materials from cut materials. In the laser cutting process, for some closely connected waste materials and cut materials, the existing unloading methods cannot effectively separate them. In some cases, it is necessary to use the primitive method of manual knocking or throwing to separate waste materials and cut materials. This method is inefficient and increases production costs and production cycles. In summary, the existing laser cutting machine unloading technology has problems such as low efficiency and difficulty in waste separation, which seriously restricts the application of laser cutting technology in efficient production. A new unloading technology is urgently needed to solve these problems. Summary of the invention

After the conveying plate approaches the clamping space, the conveying plate begins to tilt and swing, so that the waste frame and the finished product fall freely into the clamping space. The clamping space clamps the edge of the waste frame. After the conveying plate slides at least a distance of the finished product according to the set program, the sliding plate begins to slide in the opposite direction. Since the conveying plate is in an inclined state at this time, with the reverse sliding of the conveying plate and the clamping of the clamping space, the cut waste frame slides down from the conveying plate little by little, and the finished product falls into the receiving cavity from the blanking gap. After the sliding plate slides in the opposite direction, the clamping space and the waste frame on the conveying plate are supported. A driving member can be designed to drive the sliding plate to reset later, or manual reset can be used. After manual reset, the waste frame on the sliding plate can be removed for the next operation. Since the laser cutting machine in this embodiment completely cuts the finished product, the distance between the conveying plate and the sliding plate during the reverse sliding process is at least the distance of a finished product, so the finished product will fall into the material receiving chamber below from the blanking gap between the conveying plate and the sliding plate, and the waste frame is supported by the sliding plate. Through the coordinated action of the above-mentioned sliding plate and conveying plate, the separation and collection of the two can be well achieved, which speeds up the material unloading efficiency.

[0040] Compared with the traditional manual unloading or gripping method, the unloading and separation process of the plate cutting machine is more efficient. It can quickly and orderly process a large amount of cut materials after cutting. Whether it is a small batch or a large batch of plate cutting operations, the finished product and the waste frame can be quickly separated and collected, which greatly improves production efficiency and reduces the time waste in the unloading link. In addition, the unloading structure is simple, low-cost and easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings.

[0056] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0058] Reference Figure 1 to Figure 12, which is the first embodiment of the present invention, proposes a plate cutting machine for cutting plates to form finished products and waste frames after cutting, including a frame 1, the frame 1 has a material receiving chamber 16; a sliding plate 2 is slidably arranged on the frame 1, and after the sliding plate 2 slides, it slides into or out of the material receiving chamber 16; a clamp 6 is arranged on the frame 1 and is located above the sliding plate 2, and the clamp 6 has a clamping space 61; a conveying plate 3 is slidably and rotatably arranged on the frame 1, and the finished product and the waste frame are placed on the conveying plate 3, with the direction of the conveying plate 3 approaching the material receiving chamber 16 as the positive direction, after the conveying plate 3 slides and rotates positively, one end of the waste frame slides into the clamping space 61, and after the conveying plate 3 slides in the reverse direction, a blanking gap is formed with the sliding plate 2, and the finished product passes through the blanking gap and enters the material receiving chamber 16, and after the sliding plate 2 slides in the reverse direction, it supports the waste frame.

[0059] In this embodiment, in an industrial production workshop, the plate is placed on the cutting table of a laser cutting machine for cutting. After the cutting is completed, a finished part and a surrounding waste frame are formed. The conveying plate 3 slides forward toward the receiving chamber 16 through its sliding and swinging mechanism. After the conveying plate 3 approaches the clamping space 61, the conveying plate 3 begins to tilt and swing, allowing the waste frame and the finished product to fall freely. The end of the waste frame close to the clamping space 61 slides into the clamping space 61, and the clamping space 61 clamps the edge of the waste frame. After the conveying plate 3 slides at least the distance of a finished product according to the set program, the sliding plate 2 starts to slide in the opposite direction. Since the conveying plate 3 is in an inclined state at this time, with the reverse sliding of the conveying plate 3 and the clamping of the clamping space 61, the cut waste frame slides down from the conveying plate 3 little by little, and the finished product falls into the receiving chamber 16 from the blanking gap. After the sliding plate 2 slides in the reverse direction, the clamping space 61 and the waste frame on the conveying plate 3 are supported. A driving member can be designed to drive the sliding plate 2 to reset later, or manual reset can be used. After manual reset, the waste frame on the sliding plate 2 can be removed for the next operation. Since the laser cutting machine in this embodiment completely cuts the finished product, the distance between the conveying plate 3 and the sliding plate 2 during the reverse sliding process is at least the distance of a finished product, so the finished product will fall from the blanking gap between the conveying plate 3 and the sliding plate 2 into the receiving chamber 16 below, and the waste frame is supported by the sliding plate 2. Through the above-mentioned coordinated action of the sliding plate 2 and the conveying plate 3, the separation and collection of the two can be well achieved, which speeds up the efficiency of material unloading.

[0060] Compared with the traditional manual unloading or gripping method, the unloading and separation process of the plate cutting machine is more efficient. It can quickly and orderly process a large amount of cut materials after cutting. Whether it is a small batch or a large batch of plate cutting operations, the finished product and the waste frame can be quickly separated and collected, which greatly improves production efficiency and reduces the time waste in the unloading link. In addition, the unloading structure is simple, low-cost and easy to maintain.

[0061] Furthermore, one end of the conveying plate 3 close to the receiving chamber 16 is rotatably and slidably set on the frame 1, the first telescopic member 4 is slidably set on the frame 1, and the other end of the conveying plate 3 is set on the first telescopic member 4. After the first telescopic member 4 contracts, it drives the conveying plate 3 to rotate.

[0062] In this embodiment, after the finished product and the waste frame after cutting are sent to the conveying plate 3, the first telescopic member 4 located on the frame 1 starts to start. Since the first telescopic member 4 is slidably arranged on the frame 1, the first telescopic member 4 can slide forward and backward following the conveying plate 3. After the conveying plate 3 drives the first telescopic member 4 to slide into place, the first telescopic member 4 starts to extend according to the preset program. During the extension process, due to the swing connection restriction at one end of the conveying plate 3, the conveying plate 3 will swing around the swing connection point between it and the frame 1, and the other end of the conveying plate 3 will gradually lift up, so that the conveying plate 3 tilts toward the clamping space 61, and the finished product and the waste frame slide toward the clamping space 61. After the edge of the waste frame slides into the clamping space 61, it is clamped by the clamping space 61. Then, the conveying plate 3 drives the sliding plate 2 to slide in the opposite direction. As mentioned above, the finished product passes through the blanking gap and falls into the receiving cavity 16. The sliding plate 2 slides in the opposite direction, and the waste frame falls on the sliding plate 2. The automatic telescopic movement of the first telescopic member 4 further improves the automation level of the entire plate cutting machine. After the cutting is completed, there is no need for manual intervention in the movement of the conveying plate 3, and the equipment can automatically complete the conveying of the cut material and the subsequent material separation operation according to the preset program, which reduces the labor intensity of manpower.

[0063] Furthermore, the supporting plate 31 is slidably and swingably set on the frame 1, and the other end of the supporting plate 31 is set on the first telescopic member 4; the movable plate 32 is swingably set on the other end of the supporting plate 31, and after the movable plate 32 is colinear with the supporting plate 31, it is used to transport the waste frame and the finished product. After the movable plate 32 swings, it is perpendicular to the supporting plate 31, and is used to push the waste frame and the finished product to slide into the clamping space 61.

[0064] In this embodiment, the plate is too heavy, resulting in excessive friction between the plate and the conveying plate 3, which causes the waste frame and the finished product to be unable to slide down after the conveying plate 3 is tilted. Therefore, in this embodiment, after the conveying plate 3 slides, the movable plate 32 is driven to flip to a vertical state, and the scrap frame and the finished product after cutting are assisted to slide during the flipping process. The movable plate 32 is in line with the supporting plate 31, and the movable plate 32 and the supporting plate 31 jointly support the scrap frame and the finished product. As the supporting plate 31 and the movable plate 32 slide, the movable plate 32 gradually swings to the supporting end face of the supporting plate 31, and is perpendicular to the supporting end face, exerting a force on the scrap frame and the finished product, so that the edge of the scrap frame slides into the clamping space 61.

[0065] The combined design of the support plate 31 and the movable plate 32 makes the conveying plate 3 have more flexible and diverse functions. The support plate 31 is mainly responsible for transporting the cut plates to an area close to the sliding plate 2 within a larger range, while the movable plate 32 can perform pushing operations at key material unloading nodes. This division of labor and cooperation can adapt to the transportation needs of cut materials of different shapes, sizes and weights. For large and heavy plates, the support plate 31 can provide stable support and transportation; for small or difficult to push directly cut materials, the movable plate 32 can be adjusted and pushed through its rotation and sliding movements, which improves the success rate and efficiency of unloading.

[0066] Furthermore, the frame 1 has a first protrusion 11 and a second protrusion 12, and the first protrusion 11 and the second protrusion 12 form a sliding space 13. The conveying plate 3 is slidably arranged in the sliding space 13. One end of the third connecting rod 51 is arranged on the movable plate 32, and the other end is rotatably arranged on the supporting plate 31. After the third connecting rod 51 swings, it drives the movable plate 32 to swing; the fourth connecting rod 52 is arranged on the third connecting rod 51, and the third connecting rod 51 and the fourth connecting rod 52 have an angle. After the fourth connecting rod 52 slides forward, it abuts against the first protrusion 11, and after the fourth connecting rod 52 slides reversely, it abuts against the second protrusion 12.

[0067] In this embodiment, in the plate cutting production line, after the laser cutting process is completed, the supporting plate 31 starts to slide forward under the drive of the power device, because the conveying plate 3 composed of the supporting plate 31 and the moving plate 32 is slidably arranged in the sliding space 13 formed by the first protrusion 11 and the second protrusion 12 of the frame 1. When the supporting plate 31 slides forward, the third connecting rod 51 and the fourth connecting rod 52 slide together with the supporting plate 31, and when sliding to a certain position, the fourth connecting rod 52 contacts the second protrusion 12. Due to the obstruction of the second protrusion 12, as the supporting plate 31 continues to slide forward, the second protrusion 12 will apply a force to the fourth connecting rod 52, so that the fourth connecting rod 52 drives the third connecting rod 51 to start rotating around the rotation connection point between the third connecting rod 51 and the supporting plate 31, and during the rotation, the third connecting rod 51 will drive the moving plate 32 to swing. The moving plate 32 gradually rotates from a state colinear with the supporting plate 31 to a vertical state, thereby pushing the cut plate onto the sliding plate 2.

[0068] After the unloading operation is completed, the supporting plate 31 starts to slide in the reverse direction. During the reverse sliding process, the fourth connecting rod 52 will abut against the first protrusion 11. The first protrusion 11 will generate a reaction force on the fourth connecting rod 52. This force is transmitted to the moving plate 32 through the third connecting rod 51, driving the moving plate 32 to perform a reset operation.

[0069] With the help of the design of the first protrusion 11, the second protrusion 12, the third connecting rod 51 and the fourth connecting rod 52 on the frame 1, the action conversion and cooperative work between the supporting plate 31 and the movable plate 32 are realized. In different working stages, such as when the conveying plate 3 is conveying forward and resetting in the reverse direction, the posture of the movable plate 32 can be automatically adjusted according to the interaction of the mechanical structure, ensuring that the cut material can be properly handled in each unloading operation, and improving the reliability of the unloading process. The mechanical structure realizes the action control of each part of the conveying plate 3 through the interaction of the physical structure. Compared with the complex electronic control system to control the movement of the supporting plate 31 and the movable plate 32 respectively, it greatly simplifies the design and programming difficulty of the control system. It reduces the dependence on high-precision sensors, complex controllers and a large number of control circuits, and reduces the manufacturing cost of the equipment. At the same time, since the mechanical structure is relatively stable and reliable, the risk of equipment shutdown due to electronic component failure is reduced, the overall stability and maintainability of the equipment are improved, and the maintenance cost and maintenance difficulty of the equipment are reduced.

[0070] Furthermore, one end of the supporting plate 31 has a slot 54, and one end of the sliding plate 2 has a snap-in protrusion 33. After the supporting plate 31 swings, the snap-in protrusion 33 snaps into the slot 54, and the supporting plate 31 and the sliding plate 2 form a blanking gap. After the supporting plate 31 slides in the reverse direction, it drives the sliding plate 2 to slide in the reverse direction.

[0071] In this embodiment, after the support plate 31 rotates, due to the clamping effect of the clamping protrusion 33 and the clamping groove 54, the support plate 31 can drive the sliding plate 2 connected thereto to slide in the opposite direction when sliding in the opposite direction. The design of the clamping protrusion 33 and the clamping groove 54 realizes the power transmission between the support plate 31 and the sliding plate 2. Even if the clamping groove 54 and the clamping protrusion 33 are connected, a blanking gap is still formed between the sliding plate 2 and the conveying plate 3. Two telescopic rods can be designed at one end of the support plate 3 close to the clamping space 61. The two telescopic rods are located on both sides of the conveying plate 3, and the clamping groove 64 is designed on the telescopic rod. In this way, the blanking gap can be formed, and the conveying plate 3 can drive the sliding plate 2 to slide in the opposite direction. The size of the blanking gap can also be adjusted by adjusting the length of the telescopic rod to be extended, thereby separating finished products and waste frames of different sizes. This telescopic rod cannot be automatically extended and retracted, and can only be extended and retracted manually. After the manual extension, the length of the telescopic rod is fixed. In the process of reverse sliding, this connection method can effectively transmit the power of the support plate 31 to the sliding plate 2, ensuring that the sliding plate 2 moves according to a predetermined trajectory and speed. This type of clamping structure can withstand greater tension and shear forces, and will not cause connection failure due to changes in the weight of the cutting material or vibration during movement. It improves the reliability and stability of the equipment during the material unloading process, reduces equipment downtime caused by power transmission failure, and is conducive to improving production efficiency.

[0072] This snap-on connection structure is relatively simple. Compared with some complex transmission methods to realize the linkage between the support plate 31 and the sliding plate 2, it does not require a large number of precision parts and complex assembly processes. This not only reduces the manufacturing cost of the equipment, but also makes it more convenient and quick during equipment maintenance and repair. If the snap-on protrusion 33 or the slot 54 is worn or damaged, the cost and difficulty of replacing a single component are relatively low, and there is no need to disassemble and debug the entire transmission system on a large scale, which reduces the maintenance time and cost of the equipment and improves the overall maintainability and service life of the equipment.

[0073] Furthermore, the frame 1 has a sliding hole 14, the sliding plate 2 is reciprocatingly slidably arranged in the sliding hole 14, the supporting plate 62 is arranged in the sliding hole 14, and the pressing plate 63 located above the sliding plate 2 is lifted and lowered in the sliding hole 14, the supporting plate 62 and the pressing plate 63 form a clamping space 61, and after the pressing plate 63 descends, it is used to squeeze the waste frame with the supporting plate 62.

[0074] In this embodiment, the sliding plate 2 is slidably arranged in the sliding hole 14 of the frame 1 and the supporting sheet 62 above the sliding plate 2 plays the role of supporting the waste frame. Subsequently, the pressing sheet 63 begins to descend under the action of the lifting drive device. For example, when cutting a heavy plate, the edge of the waste frame may be driven by the conveying plate 3 to slide in the opposite direction. After the pressing sheet 63 descends, it cooperates with the supporting sheet 62 to squeeze the edge of the waste frame from the top and bottom directions. During the squeezing process, the waste frame is subjected to pressure, and the waste frame slides relative to the conveying plate 3. The waste frame stays in the clamping space 61 more stably. The arrangement of the supporting sheet 62 and the pressing sheet 63 effectively improves the stability of waste collection.

[0075] Further, the sliding plate 2 has guide grooves 21 on both sides, and the guide grooves 21 have a first inclined groove 211, a first horizontal groove 212, a second inclined groove 213 and a second horizontal groove 214 that are connected in sequence. One end of the first connecting rod 8 is rotatably set on the pressing plate 63, and the other end is slidably set in the guide groove 21. After the other end of the first connecting rod 8 slides along the first inclined groove 211, it drives the pressing plate 63 to descend. After the other end of the first connecting rod 8 is slidably set in the first horizontal groove 212, it drives the pressing plate 63 to squeeze the waste frame. After the other end of the first connecting rod 8 slides along the second inclined groove 213, it drives the pressing plate 63 to rise. After the other end of the first connecting rod 8 is slidably set in the second horizontal groove 214, the pressing plate 63 and the supporting plate 62 form a clamping space 61; the guide plate 160 is rotatably set in the first horizontal groove 212, and the other end of the first connecting rod 8 passes through the guide plate 160 and slides from the first horizontal groove 212 into the second inclined groove 213.

[0076] After the sliding plate 2 slides forward, due to the obstruction of the guide plate 160, the other end of the first connecting rod 8 rises along the second inclined groove 213, the pressing plate 63 rises, and the waste frame is stopped. The sliding plate 2 drives the waste frame through the sliding hole 14, and the sliding plate 2 drives the waste frame to pass through the sliding hole 14, and the waste frame is reciprocated in this way. The waste frame on the sliding plate 2 can be removed mechanically or manually.

[0077] The design of the first chute 211 and the second chute 213 controls the descending height and speed of the pressing sheet 63, thereby avoiding the adverse effects of the pressing sheet 63 descending too fast or too slowly on the separation of the waste frame and the finished product. To adjust the descending height of the pressing sheet 63, the first connecting rod 8 can be designed as a telescopic structure, and the driving member or manual active control of its telescopic structure is fixed after telescopic. The longer the length of the first connecting rod 8, the thicker the waste frame that the pressing sheet 63 can squeeze. The first horizontal groove 212 can accurately limit the squeezing position and strength of the pressing sheet 63 in the horizontal direction, improve the accuracy and effectiveness of waste material processing, and thus improve the quality and stability of the entire unloading process. The second horizontal groove 214 prevents the waste frame from being unable to slide out of the receiving cavity 16 following the sliding plate 2. This mechanical structure simplifies the structure of the equipment and reduces the manufacturing cost of the equipment. At the same time, a simple mechanical structure also means fewer failure points and lower maintenance difficulty, reducing the maintenance cost and downtime of the equipment, which is conducive to enterprises reducing operating costs in the long-term production process. In order to ensure that the first connecting rod 8 slides along the first inclined groove 211 after the sliding plate 2 slides in the reverse direction, another guide plate 160 and a torsion spring can be designed on the second horizontal groove 214 to prevent the other end of the first connecting rod 8 from sliding along the second horizontal groove 214 when the sliding plate 2 slides in the reverse direction.

[0078] Furthermore, the frame 1 has several first mounting holes 15, and the mounting plates 9 have several mounting plates 9. The mounting plates 9 are lifted and lowered in the frame 1. The several mounting plates 9 are arranged in sequence and are located above the receiving chamber 16. The mounting plates 9 have several second mounting holes 91, and the first mounting holes 15 correspond to the second mounting holes 91 one by one; there are several lifting rods 10, which pass through the first mounting holes 15 and are detachably arranged in the second mounting holes 91. The lifting rods 10 correspond to the finished products one by one. After the lifting rods 10 descend, the finished products are driven to descend; one end of the elastic member 110 is arranged on the frame 1, and the other end is arranged on the mounting plate 9. The elastic member 110 is used to provide a force for the mounting plate 9 to rise.

[0079] In this embodiment, in order to facilitate the separation of the finished product and the waste frame, a plurality of mounting plates 9 arranged in sequence in the frame 1 start to function after the sliding plate 2 slides. These mounting plates 9 are lifted and lowered in the frame 1 by the telescopic rod 5, and each mounting plate 9 is provided with a plurality of second mounting holes 91. The frame 1 is pre-set with a plurality of first mounting holes 15, and the two correspond one to one. Then, a plurality of lifting rods 10 are respectively passed through the corresponding first mounting holes 15, and can be, but not limited to, screwed into the corresponding second mounting holes 91, to ensure that each lifting rod 10 corresponds to a finished product.

[0080] When it is necessary to separate the finished product from the waste frame and make it fall into the receiving chamber 16, the conveying plate 3 slides in the reverse direction for a distance, driving the sliding plate 2 to start sliding in the reverse direction. After the sliding plate 2 slides in the reverse direction, the lifting rod 10 descends. After the lifting rod 10 descends, the finished product is separated from the waste frame and falls into the receiving chamber 16. Then the elastic member 110 drives the lifting rod 10 to rise, and the sliding plate 2 slides over a row of waste frames separated from the finished product, and so on. Since the lifting rod 10 and the mounting plate 9 can be threadedly connected, this unloading structure can separate finished products and waste frames of different shapes and sizes.

[0081] Through the cooperation of the lifting rod 10 and the mounting plate 9, the finished products can be separated accurately. Each lifting rod 10 corresponds to a finished product, so that finished products of different shapes and sizes can be individually controlled during the separation process. This one-to-one correspondence can more accurately move the finished product from the top of the waste frame to the material receiving chamber 16. This structural design composed of the frame 1, the mounting plate 9, the lifting rod 10 and the elastic member 110 is relatively flexible and can adapt to different production scenarios and plate cutting requirements. Whether it is a small number of large finished products formed by cutting large plates, or a large number of small finished products produced by cutting small plates, the needs of unloading and waste separation can be met by adjusting the number and installation position of the lifting rods 10.

[0082] Furthermore, the slider 120 is slidably arranged in the frame 1, and the slider 120 has a chamfer. After the slider 120 slides, the chamfers squeeze the mounting plate 9 down in turn; there are two second connecting rods 130, one end of the second connecting rod 130 is arranged on one end of the sliding plate 2, and the other end is arranged on the slider 120. The two second connecting rods 130 are respectively located on both sides of the slider 120. After the sliding plate 2 slides, it drives the slider 120 to slide.

[0083] In this embodiment, since one end of the sliding plate 2 is connected to the two second connecting rods 130, and the other ends of the two second connecting rods 130 are respectively arranged on both sides of the slider 120, the sliding of the sliding plate 2 will drive the slider 120 to slide in the frame 1. During the sliding process, the slider 120 will sequentially squeeze the mounting plates 9 arranged in sequence in the frame 1, driving the mounting plates 9 to descend. As the slider 120 sequentially drives the mounting plates 9 to descend, the mounting plates 9 drive the finished products to descend to the material receiving chamber 16 through the lifting rod 10. The waste frame, due to its own structural characteristics, remains on the sliding plate 2 during this process, and then as the sliding plate 2 moves further, the waste frame moves out of the material receiving chamber 16, thereby completing the entire separation and collection process of the finished product and the waste frame.

[0084] The linkage mechanism between the slider 120 and the sliding plate 2 through the second connecting rod 130 makes the entire material removal and waste separation process more efficient. The movement of the sliding plate 2 can be directly and orderly transmitted to the slider 120, thereby driving the mounting plate 9 to complete the separation operation of the finished product, reducing the complex control links and power transmission components in the middle. This linkage method can ensure that the waste separation process is quickly started after the cutting is completed, improves production efficiency, and enables the equipment to quickly process the cut materials in large-scale plate cutting production to meet the needs of efficient production.

[0085] The structural design consisting of the sliding plate 2, the second connecting rod 130, the slider 120 and the mounting plate 9 is relatively compact. No large and complex transmission mechanism or multiple independent power sources are required to separate the finished product from the waste frame. The equipment takes up less space in the production workshop, which is convenient for the layout and installation of the equipment. At the same time, the number of failure points caused by too many components and complex structure is reduced, the maintenance difficulty and maintenance cost of the equipment are reduced, and the overall stability and operability of the equipment are improved.

[0086] Furthermore, the laser knife 140 is movably set on the frame 1, and the laser knife 140 is used to cut the plate; there are a plurality of support racks 150, and the plurality of support racks 150 are cyclically transported on the frame 1, and the support racks 150 are used to support the cut plate. After the support racks 150 move, they are used to transport the cut plate to the supporting plate 31.

[0087] In this embodiment, in the plate cutting and processing workshop, the plate to be cut is first placed on the circulating support rack 150. These support racks 150 run stably on the frame 1 according to the preset track and speed to ensure that the plate is in a stable support state before cutting. When the cutting operation starts, the laser knife 140 set on the frame 1 is started according to the pre-set cutting program and accurately cuts the plate. During the cutting process, the support rack 150 continues to provide stable support to prevent the plate from being displaced or deformed due to the cutting force. After the cutting is completed, the support rack 150 continues to move to transport the cut plate containing the finished product and the waste frame to the support plate 31. Then, through the linkage action of a series of components such as the conveying plate 3 and the sliding plate 2 as described above, the separation and collection of the finished product and the waste frame are realized.

[0088] The cyclic conveying function of the support rack 150 enables the cut plates to be quickly conveyed to the support plate 31, realizing a seamless connection between the cutting and unloading links. Compared with the traditional manual handling or intermittent conveying method, the residence time of the materials between different processes is greatly shortened, thereby improving production efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
