Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting equipment, and particularly relates to a cutting equipment for wood board processing. BACKGROUND

[0002] In the production process of wood products, cutting equipment is usually used to cut the board to meet different production needs. At present, double-edge cutting machines are generally used for double-edge cutting to improve the processing efficiency of the board.

[0003] The existing double-edge cutting machine usually has two independent cutting machines placed on the same base, and the distance between the two cutting machines is adjustable. When cutting, the board is carried on the cutting seats of the two cutting machines, the upper belt and the lower belt on the cutting machine are used to clamp the board, and the board can be conveyed forward by providing opposite rotating power to the upper belt and the lower belt. During the conveying process, the cutting knife on the side of the cutting machine cuts the board to cut the excess material on the side of the board.

[0004] However, at the moment when the board is sent in, the upper edge of the board will impact the upper belt, and the surface of the upper belt will be worn out over time. The worn-out part is usually smooth, which reduces the friction between the board and the upper belt, and makes the board prone to "slip" during conveying, further causing the cutting process to be prone to board jumping, resulting in board deviation and affecting the cutting of the board. SUMMARY

[0005] In order to improve the problem that the cutting process is prone to board jumping, resulting in board deviation and affecting the cutting effect in the related art, the present application provides a cutting equipment for wood board processing.

[0006] The present application provides a cutting equipment for wood board processing, which adopts the following technical scheme:

[0007] The application discloses a cutting device for wood board processing, which comprises a base, two machine bases arranged on the base, a cutting seat and a lifting seat arranged on the machine bases, the lifting seat is arranged oppositely to the cutting seat, an upper belt is arranged on the lifting seat, a lower belt is arranged on the cutting seat, a belt groove is arranged on the lifting seat and used for arranging the upper belt, the opening of the belt groove faces the lower belt, the lower belt of the upper belt protrudes from the opening of the belt groove, a pressing plate is arranged in the belt groove and used for pressing the lower belt of the upper belt, the pressing plate is movably arranged between the upper belt and the lower belt, a swing assembly is arranged between the upper belt and the lower belt, and one end of the swing assembly is connected to the pressing plate; the swing assembly comprises an L-shaped rod arranged in the belt groove and a connecting rod, the top end of the L-shaped rod is hinged to the inner wall of the belt groove and forms a first hinge point, the other end is hinged to the connecting rod and forms a second hinge point, and the other end of the connecting rod is fixedly connected to the pressing plate; and a driving assembly is arranged in the belt groove and used for driving the L-shaped rod to swing up and down around the first hinge point.

[0008] By adopting the technical scheme, when cutting the board, the height of the lifting seat is adjusted, the upper belt is slightly higher than the surface of the board, and the abrasion of the upper belt is reduced when the board is put in. Then the board is put in, and the L-shaped rod is driven to rotate around the first hinge point by the driving assembly after the board is put in. After the L-shaped rod rotates, the end connected with the connecting rod approaches or moves away from the lower belt of the upper belt. When the L-shaped rod approaches the lower belt of the upper belt, the connecting rod also approaches the lower belt of the upper belt, so that the pressing plate presses the lower belt of the upper belt and the lower belt of the upper belt is tightly pressed against the surface of the board. When the lower belt of the upper belt is tightly pressed against the board, the board is clamped by the upper belt and the lower belt and is conveyed forward. It is worth mentioning that the connecting rod is hinged to the L-shaped rod, so that the connecting rod rotates around the second hinge point under the gravity of the pressing plate, the pressing plate approaches the lower belt of the upper belt better, and the pressing plate is more closely connected to the lower belt of the upper belt. The technical scheme reduces the abrasion of the upper belt, and increases the pressure of the lower belt on the board through the cooperation of the pressing assembly and the pressing plate, so that the board is further clamped by the upper belt and the lower belt, the slipping or jumping of the board in the conveying process is reduced, and the stability of the cutting effect is ensured.

[0009] Preferably, the number of the pressing plates is two, the number of the swing assemblies is two, and the driving assembly is used for synchronously driving the two swing assemblies to swing.

[0010] By adopting the technical scheme, the pressure range of the upper belt is larger through the arrangement of the two pressing plates, so that the upper belt is more closely connected to the board, and the clamping force of the upper clamp plate and the lower clamp plate on the board is larger.

[0011] Preferably, the driving assembly comprises a first bidirectional cylinder fixedly arranged in the belt groove and two slide rods slidably arranged on the groove wall of the belt groove, the slide rods are arranged in parallel with the conveying direction of the plate material, and the two slide rods are respectively connected to the piston rods of the first bidirectional cylinder, one end of the slide rod away from the first bidirectional cylinder is provided with a slide sleeve, the slide sleeve is sleeved on one end of the L-shaped rod close to the first hinge point, and the slide sleeve and the L-shaped rod are in sliding fit.

[0012] By adopting the above technical scheme, when the first bidirectional cylinder drives the two slide rods to move, the L-shaped rod starts to rotate, and the connection point of the L-shaped rod and the slide rod changes, and since the slide rod and the L-shaped rod are in sliding connection, the change of the connection point of the L-shaped rod and the slide rod can be adapted, so that the L-shaped rod is rotated by the thrust of the slide rod.

[0013] Preferably, the groove wall of the belt groove is provided with two guide sleeves corresponding to the two slide rods respectively, the slide rods are arranged in the guide sleeves and are in sliding fit with the guide sleeves.

[0014] By adopting the above technical scheme, the guide sleeve can make the sliding direction of the slide rod more stable, so as to better drive the L-shaped rod to swing.

[0015] Preferably, the cutting seat is provided with a clamp for clamping the front end of the plate material, and the cutting seat is also provided with a bidirectional conveying assembly for driving the clamp to move back and forth along the conveying direction of the plate material.

[0016] By adopting the above technical scheme, when the plate material is placed, the clamp clamps the edge of the plate material, and at the same time, the clamp moves at the same speed as the plate material under the conveying of the conveying belt, which can further reduce the "slip" of the plate material, so that the plate material is conveyed more stably, and the cutting effect is further ensured.

[0017] Preferably, the bidirectional conveying assembly comprises a driving roller rotatably arranged on the cutting seat, a driven roller, a driving mechanism for driving the driving roller to rotate, and a conveying belt surrounding the driving roller and the driven roller, the conveying belt is arranged in parallel with the lower belt, and one end of the clamp is connected to the upper belt of the conveying belt.

[0018] By adopting the above technical scheme, the driving mechanism drives the driving roller to rotate, so as to drive the conveying belt to rotate, and then the clamp moves along the conveying direction of the plate material. The output end of the driving mechanism reverses the operation, so that the conveying belt reverses the rotation, so as to realize the back movement of the clamp.

[0019] Preferably, the clamp comprises a mounting base connected with the conveying belt, a mounting rod connected with the mounting base, and an upper clamping plate and a lower clamping plate slidingly arranged on the mounting rod along the length direction of the mounting rod, and a second bidirectional air cylinder is arranged on one side of the mounting rod, and the piston rods at both ends of the second bidirectional air cylinder are respectively connected with the upper clamping plate and the lower clamping plate.

[0020] By adopting the technical scheme, the piston rods of the second bidirectional air cylinder are extended to drive the upper clamping plate and the lower clamping plate to move away from each other along the vertical direction of the mounting rod, so as to realize the opening of the two clamping plates. When clamping the plate, the piston rods of the second bidirectional air cylinder are retracted to make the upper clamping plate and the lower clamping plate close to each other and tighten the plate.

[0021] Preferably, the mounting rod comprises a fixed segment fixedly connected with the mounting base and a rotating segment hingedly connected with the fixed segment, the rotating segment is arranged in an L shape, the rotating segment comprises a vertical part slidingly matched with the upper clamping plate and the lower clamping plate, and an inclined part hingedly connected with the fixed segment and arranged in an upward inclination, a third hinge point is formed at the hinged position of the inclined part and the fixed segment, and a rotating assembly for driving the rotating segment to rotate around the third hinge point is arranged on the mounting base.

[0022] By adopting the technical scheme, when the plate is cut and has not completely left the lower belt, the clamp needs to be sent back to the initial clamping position to ensure that the next plate to be cut is clamped in time. Due to the blockage of the current plate, the clamp needs to be processed when it is sent back. Through the driving of the rotating assembly, the rotating segment is rotated around the third hinge point to the direction away from the plate, so that the rotating segment is folded to achieve the effect of giving way, so that the clamp is conveyed back to the initial clamping position from the lower side of the plate.

[0023] Preferably, the rotating assembly comprises a cylinder vertically arranged on the mounting base, a force applying rod connected with the piston rod of the cylinder, and a force applying block connected with one end of the force applying rod, the piston rod of the cylinder is arranged upward, the force applying rod is connected with the top end of the piston rod of the cylinder, the force applying block is provided with a through hole, the rotating segment is provided with a support rod, the support rod extends to the side facing the cylinder, the support rod passes through the through hole, and the hole wall of the through hole and the support rod have a movable gap.

[0024] By adopting the technical scheme, when the piston rod of the cylinder retracts, the force applying rod moves downward and presses the force applying block downward, so that the force applying block moves downward. When the force applying block abuts against the supporting rod, the piston rod of the cylinder continues to retract, so that the force applying block exerts a downward pressure on the supporting rod. The supporting rod is subjected to the downward pressure, and the rotating section starts to rotate in a direction away from the plate. When the rotating section rotates, the supporting rod also rotates and presents an inclination change in the through hole, the movable gap is arranged between the hole wall of the through hole and the supporting rod, so that the supporting rod can be smoothly inclined and slide against the force applying block, and then the rotating section is turned over in a direction away from the plate.

[0025] Preferably, a spring is arranged between the inclined part and the mounting seat, and two ends of the spring are correspondingly connected to the inclined part and the mounting seat respectively.

[0026] By adopting the technical scheme, when the rotating section rotates, the spring is compressed, and when the piston end of the cylinder extends upward, the spring restores and assists the rotating section to better reset.

[0027] To sum up, the present application has at least one of the following beneficial technical effects:

[0028] 1. By increasing the height of the upper belt and increasing the pressing plate to press the lower belt of the upper belt, the wear of the upper belt is reduced, and the pressure exerted by the upper belt on the plate is increased, the jumping or slipping of the plate is reduced, and the stability of cutting is ensured; 2. The clamps are arranged during cutting to hold the plate, which can better convey the plate and further reduce the poor cutting effect caused by the "slipping" of the plate.

[0037] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0038] A cutting device for wood panel processing, see attached figure. Figure 1 The system includes a cuboid base 1, two machine bases 2 spaced apart along the length of the base 1, and a cutting seat 3 and a lifting seat 4 mounted on the machine bases 2. The lifting seat 4 and the cutting seat 3 are arranged vertically opposite each other. One side of the machine base 2 is the feeding side 23, and the other side is the discharging side 24. Both feeding sides 23 of the machine base 2 are horizontally equipped with feeding racks 25, which are located on the same horizontal plane and are parallel to each other. One end of the feeding rack 25 is fixedly connected to the cutting seat 3, and the other end extends away from the cutting seat 3. Guide plates 26 are provided on the opposite sides of the two feeding racks 25. One end of the guide plate 26 is fixedly connected to the machine base 2, and the other end extends away from the machine base 2. The top of the guide plate 26 is higher than the top of the feeding rack 25, and a trapezoidal guide opening 27 is formed between the two guide plates 26, which gradually narrows towards the machine base 2. A connecting rib 28 is provided between the guide plate 26 and the feeding rack 25 to enhance the stability of the guide plate 26.

[0039] Referring to the drawings Figure 2 and the drawings Figure 3 Two machine bases 2 are arranged on the base 1, one of which is fixedly arranged on the base 1, and the other is slidably arranged on the base 1, so as to adjust the distance between the two machine bases 2, so as to adapt to the cutting needs of different plates. Specifically, the guide rail 29 is arranged on the base 1 along the length direction, and the sliding groove 30 is arranged at the bottom of the machine base 2, and the sliding groove 30 is slidably matched with the guide rail 29. The driving structure 31 for driving the machine base 2 to slide is arranged on the base 1, one end of the driving structure 31 is connected with the machine base 2, and in the embodiment, the driving structure 31 can be one of a lead screw motor, a pneumatic cylinder or an oil cylinder. The guide rod 32 is arranged on the base 1 along the length direction of the base 1, and the guide block 33 is arranged on one side of the machine base 2 which can slide, and the guide rod 32 passes through the guide block 33. By cooperating the guide block 33 with the guide rod 32, the sliding of the machine base 2 is more stable.

[0040] Referring to the drawings Figure 2 and the drawings Figure 3 The lower belt 6 is arranged horizontally on the cutting seat 3, and a plurality of discharge ports 34 for allowing the wood chips generated during cutting of the plate to fall are arranged on the lower belt 6. The upper belt 5 is arranged horizontally on the lifting seat 4, and the upper belt 5 is arranged opposite to the lower belt 6. The cutting knife 35 is arranged on one side of the cutting seat 3 close to the machine base 2, and the cutting knife 35 is a disc cutting knife.

[0041] During cutting, the lifting seat 4 is driven to descend, so that the gap for the plate to pass through is formed between the upper belt 5 and the lower belt 6, then the plate is placed on the feeding rack 25, and the plate is pushed forward. During the pushing process, as the guide port 27 gradually narrows, the plate gradually centers during the forward pushing process, and the front end of the plate enters between the upper belt 5 and the lower belt 6. Then, the upper belt 5 and the lower belt 6 on the cutting machine are used to clamp the plate, and the plate can be conveyed forward by providing opposite rotating power to the upper belt 5 and the lower belt 6. During the forward conveying process, the cutting knife 35 is used to cut the plate to cut the excess material on the side of the plate.

[0042] Referring to the drawings Figure 3 and the drawings Figure 4, specifically, the lifting seat 4 is provided with a belt groove 7, and the opening of the belt groove 7 faces the lower belt 6. The driving master roller 36 and the driving slave roller 37 are arranged in the belt groove 7, the upper belt 5 is wound around the driving master roller 36 and the driving slave roller 37, and the lower belt of the upper belt 5 protrudes from the opening of the belt groove 7. The base 1 is provided with a power assembly for driving the driving master roller 36 to rotate, and the power assembly includes a power motor 381 arranged on the base 1, a driving gear 382 sleeved on the output shaft of the power motor 381, a protective cover 383 arranged on the base 1, a driven gear 384 rotatably arranged in the protective cover 383, and a transmission chain 385 arranged between the driving gear 382 and the driven gear 384. The two ends of the transmission chain 385 are engaged with the driving gear 382 and the driven gear 384. In this embodiment, the power motor 381 is an existing motor, the top end of the protective cover 383 is higher than the cutting table, the driven gear 384 is arranged inside the top end of the protective cover 383, and the shaft of the driven gear 384 penetrates out of the protective cover 383 and faces one side of the lifting table.

[0043] Referring to the accompanying Figure 3 and the accompanying Figure 4 The end of the driven gear 384 penetrating out of the protective cover 383 is provided with a first hinged seat 39, one end of the driving master roller 36 penetrating out of the lifting seat 4 faces one side of the protective cover 383, and the end penetrating out of the driving master roller 36 is provided with a second hinged seat 40. The first hinged seat 39 and the second hinged seat 40 are provided with universal shaft couplings 41, and the two ends of the universal shaft couplings 41 are provided with hinged tables 42 hinged with the first hinged seat 39 and the second hinged seat 40. The hinged tables 42 and the first hinged seat 39 and the second hinged seat 40 are provided with activity gaps 43 for the upward and downward movement of the universal shaft couplings 41, so that the shaft of the driven gear 384 and the driving master roller 36 can maintain normal transmission connection when the lifting seat 4 is lifted.

[0044] When the output of the power motor 381 drives the drive gear 382 to rotate, the transmission chain 385 meshes with both the drive gear 382 and the driven gear 384. Therefore, when the drive gear 382 rotates, its teeth pass into the gaps between the rollers of the transmission chain 385, thereby driving the transmission chain 385 to rotate, which in turn causes the driven gear 384 to rotate synchronously. As the driven gear 384 rotates, the universal coupling 41 also rotates, causing the drive roller 36 to rotate. When the drive roller 36 rotates, under the transmission action of the upper belt 5, it drives the driven roller 37 to rotate, ultimately causing the entire upper belt 5 to rotate. When the lifting seat 4 rises and falls, the upper belt 5 rises and falls accordingly, causing the end of the universal coupling 41 that is hinged to the second hinge seat 40 to move vertically. Since the other end of the universal coupling 41 is connected to the driven gear 384, and the horizontal height of the driven gear 384 remains unchanged, the two ends of the universal coupling 41 are hinged together so that they can rotate up and down within the reserved movable gap 43, thereby adapting to the adjustment of the vertical height of the belt groove 7.

[0045] See attached document Figure 5 Two L-shaped rods 91 are inclinedly arranged inside the belt groove 7, symmetrically positioned between the upper and lower belts of the upper belt 5. The top ends of the L-shaped rods 91 are hinged to the inner wall of the belt groove 7, forming a first hinge point 20. The L-shaped rods 91 can move closer to or away from the lower belt of the upper belt 5 around the first hinge point 20. The other end of the L-shaped rods 91 is hinged to a connecting rod 92. Two connecting rods 92 are symmetrically arranged, and each connecting rod 92 is connected to a pressure plate 8 for pressing against the lower belt of the upper belt 5. The hinge point between the connecting rod 92 and the L-shaped rod 91 is the second hinge point 21. When the L-shaped rod 91 rotates around the first hinge point 20 towards the lower belt of the upper belt 5, the connecting rod 92 also moves closer to the lower belt of the upper belt 5, thereby causing the pressure plate 8 to press down against the lower belt of the upper belt 5, making the lower belt of the upper belt 5 protrude further out of the opening of the belt groove 7, thus pressing the plate tightly.

[0046] See attached document Figure 5 The belt groove 7 is also provided with a drive assembly 10 for driving the L-shaped rod 91 to rotate around the first hinge point 20. The drive assembly 10 includes a first bidirectional cylinder 101 fixedly disposed on the groove wall of the belt groove 7 and two slide rods 102 slidably disposed on the groove wall of the belt groove 7.

[0047] See attached document Figure 5Specifically, the groove wall of the belt groove 7 is provided with two groups of guide sleeves 12, which extend along the conveying direction of the plate. Each slide rod 102 is correspondingly provided in a guide sleeve 12 and is in sliding cooperation with the guide sleeve 12. The two slide rods 102 are respectively connected to the piston rods at the two ends of the first double-acting cylinder 101. The end of the slide rod 102 away from the first double-acting cylinder 101 is provided with a sliding sleeve 11, which is sleeved on the end of the L-shaped rod 91 close to the first hinge point 20 and is in sliding cooperation with the L-shaped rod 91. When the first double-acting cylinder 101 drives the two slide rods 102 to move, the L-shaped rod 91 starts to rotate, and the connection point of the L-shaped rod 91 and the slide rod 102 changes. Since the slide rod 102 is in sliding connection with the L-shaped rod 91, it can adapt to the change of the connection point of the L-shaped rod 91 and the slide rod 102, so that the L-shaped rod 91 is rotated by the thrust of the slide rod 102.

[0048] Referring to the accompanying drawings Figure 6 The cutting seat 3 is provided with a clamp 13 for clamping the front end of the plate and a double-acting conveying assembly for driving the clamp 13 to move back and forth along the conveying direction of the plate. The double-acting conveying assembly includes a driving roller 141 rotatably arranged on the cutting seat 3, a driven roller 142, a driving mechanism 143 for driving the driving roller 141 to rotate, and a conveying belt 144 surrounding the driving roller 141 and the driven roller 142. The conveying belt 144 is arranged between the lower belt 6 and the cutting knife 35 and is arranged parallel to the lower belt 6. One end of the clamp 13 is connected to the upper belt of the conveying belt 144. After the plate is placed, the clamp 13 clamps the edge of the plate. Then the driving mechanism 143 drives the driving roller 141 to rotate, so that the driven roller 142 rotates and drives the entire conveying belt 144 to rotate, thereby making the clamp 13 move at the same speed as the plate under the conveying of the conveying belt, so as to achieve the effect of assisting the plate conveying, further reducing the "slip" of the plate, and ensuring the cutting stability.

[0049] Referring to the accompanying drawings Figure 6 and the accompanying drawings Figure 7 Further, the clamp 13 includes a mounting seat 131 connected with the conveying belt 144, a mounting rod arranged vertically on the mounting seat 131, and an upper clamp plate 133 and a lower clamp plate 134 arranged in sliding cooperation along the length direction of the mounting rod. One side of the mounting rod is provided with a second double-acting cylinder 15, and the piston rods at the two ends of the second double-acting cylinder 15 are respectively connected to the upper clamp plate 133 and the lower clamp plate 134. The piston rods of the second double-acting cylinder 15 are extended to drive the upper clamp plate 133 and the lower clamp plate 134 to move away from each other in the vertical direction of the mounting rod, so as to realize the opening of the two clamp plates. When clamping the plate, the piston rods of the second double-acting cylinder 15 are retracted to make the upper clamp plate 133 and the lower clamp plate 134 close to each other and tighten the plate.

[0050] When the plate is cut but not completely away from the lower belt 6, the clamp 13 needs to be sent back to the starting clamping position to ensure timely clamping of the next plate to be cut. Due to the obstruction of the current plate, the clamp 13 needs to be sent back and needs to be processed.

[0051] Referring to the accompanying drawings Figure 7 , specifically, the mounting rod includes a fixed segment 1321 fixedly connected with the mounting base 131 and a rotating segment 1322 hingedly connected with the fixed segment 1321, the rotating segment 1322 is L-shaped, and includes a vertical portion slidingly matched with the upper clamp plate 133 and the lower clamp plate 134 and an inclined portion hingedly connected with the fixed segment 1321 and upwardly inclined. A third hinge point 22 is formed at the hinged connection of the inclined portion and the fixed segment 1321, and the mounting base 131 is provided with a rotating assembly 16 for driving the rotating segment 1322 to rotate around the third hinge point 22. Through the driving of the rotating assembly 16, the rotating segment 1322 is rotated around the third hinge point 22 away from the plate, i.e. the rotating segment 1322 is folded, achieving the effect of giving way, so that the clamp 13 is conveyed back from below the plate to the starting clamping position.

[0052] Referring to the accompanying drawings Figure 7 , the rotating assembly 16 includes a cylinder 161 vertically arranged on the mounting base 131, a force applying rod 162 connected to the piston rod of the cylinder 161, and a force applying block 163 connected to one end of the force applying rod 162. The piston rod of the cylinder 161 is upwardly arranged, the force applying rod 162 is arranged parallel to the conveying direction of the plate, one end of the force applying rod 162 is fixedly connected to the top end of the piston rod of the cylinder 161, and the other end is fixedly connected to the force applying block 163. The force applying block 163 is provided with a through hole 17, and the connection between the rotating segment 1322 and the fixed segment 1321 is provided with a support rod 18 parallel to the conveying direction of the plate, the support rod 18 extends toward the side of the cylinder 161 and passes through the through hole 17, and the hole wall of the through hole 17 and the support rod 18 have a movable gap therebetween.

[0053] When the piston rod of the cylinder 161 retracts, the force applying rod 162 moves downward with it and presses downward on the force applying block 163, so that the force applying block 163 moves downward. When the force applying block 163 moves to abut against the support rod 18, the piston rod of the cylinder 161 continues to retract, so that the force applying block 163 exerts a downward pressure on the support rod 18. After the support rod 18 is subjected to the downward pressure, the rotating segment 1322 starts to rotate around the third hinge point 22 away from the plate. When the rotating segment 1322 rotates, the support rod 18 also rotates and presents an inclined change in the through hole 17. By providing a movable gap between the hole wall of the through hole 17 and the support rod 18, the support rod 18 can smoothly incline and slide against the force applying block 163, thereby realizing the overturning of the rotating segment 1322 away from the plate.

[0054] Referring to the accompanying drawings Figure 7Further, the supporting rod 18 is provided with a limiting block at one end close to the cylinder 161 for limiting the sliding of the force applying block 163 out of the supporting rod 18.

[0055] In order to better reset the clamp 13 after folding, a spring 19 is vertically arranged between the inclined part and the mounting base 131, and the two ends of the spring 19 are correspondingly connected to the inclined part and the mounting base 131. When the rotating section 1322 rotates, the spring 19 is compressed, and when the piston end of the cylinder 161 extends upward, the spring 19 resets to assist the rotating section 1322 to better reset.

[0056] Referring to the drawings Figure 7 In addition, in order to further increase the clamping force of the clamp 13, a non-slip pad 44 is arranged on the opposite side of the upper clamping plate 133 and the lower clamping plate 134. The friction between the non-slip pad 44 and the wood plate is greater, so that the clamping force of the clamp 13 is greater.

[0057] The implementation principle of the embodiment is that when cutting the plate, the height of the lifting seat 4 is first adjusted, so that the upper belt 5 is slightly higher than the surface of the plate, thereby reducing the wear of the upper belt 5 when the plate is put in. Then the plate is put in, and after the plate is put in, the first double-action cylinder 101 drives the sliding rod 102 to slide in the guide sleeve 12, so that the L-shaped rod 91 rotates around the first hinge point 20. After the L-shaped rod 91 rotates, one end connected with the connecting rod 92 approaches or moves away from the lower belt of the upper belt 5. When the L-shaped rod 91 approaches the lower belt of the upper belt 5, the connecting rod 92 also approaches the lower belt of the upper belt 5, thereby making the pressing plate 8 press the lower belt of the upper belt 5 and making the lower belt of the upper belt 5 tightly abut against the surface of the plate. After the lower belt of the upper belt 5 abuts against the plate, the plate is clamped by the upper belt 5 and the lower belt 6 and is conveyed forward.

[0058] On the other hand, when the plate is put in, the second double-action cylinder 15 drives the clamp 13 to clamp the front end of the plate. When the clamp 13 clamps the plate, the driving motor 381 and the driving mechanism 143 are started, respectively driving the upper belt 5 and the conveying belt 144 to rotate, so that the plate and the clamp 13 move at the same speed. Under the auxiliary conveying of the clamp 13 and the conveying belt 144, the conveying of the plate is also more stable.

[0059] After the plate is cut, the second double-action cylinder 15 drives the clamp 13 to loosen the plate, and the piston rod of the cylinder 161 retracts, the force applying rod 162 moves downward and presses the force applying block 163 downward, so that the force applying block 163 moves downward. When the force applying block 163 abuts against the supporting rod 18, the piston rod of the cylinder 161 continues to retract, so that the force applying block 163 exerts downward pressure on the supporting rod 18. The supporting rod 18 is subjected to the downward pressure, so that the rotating section 1322 starts to rotate about the third hinge point 22 away from the plate. When the rotating section 1322 rotates, the supporting rod 18 also rotates and presents an inclination change in the through hole 17. By arranging a movable gap between the hole wall of the through hole 17 and the supporting rod 18, the supporting rod 18 can smoothly incline and slide against the force applying block 163, so as to realize the overturning of the rotating section 1322 away from the plate.

[0060] After the rotating section 1322 overturns, the driving mechanism 143 drives the conveying belt 144 to reversely convey, so that the clamp 13 returns to the starting clamping position from below the current plate. After returning to the starting clamping position, the piston rod of the cylinder 161 extends upward, and the rotating section 1322 is driven to reset, so as to continue to clamp the next plate to be cut.

[0061] The technical scheme reduces the wear of the upper belt 5, and increases the pressure of the lower belt 6 on the plate through the cooperation of the downward pressing assembly and the pressing plate 8, so that the plate is further clamped by the upper belt 5 and the lower belt 6, thereby reducing the slipping or jumping of the plate during conveying, and ensuring the stability of the cutting effect. The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
