Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production equipment, in particular to a gypsum board cutting device used for gypsum board production and processing. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels currently being developed. Gypsum board has been widely used in various buildings such as residential, office buildings, shops, hotels and industrial plants as interior partition walls, surface base boards and various decorative boards. When using gypsum board, it is often necessary to cut the gypsum board according to the specific space size requirements to ensure that the board can perfectly fit the surface of the wall or ceiling, making the overall decoration effect more beautiful.

[0003] Among them, the most common way to cut gypsum board is to use an electric saw to cut the gypsum board. However, electric saw cutting may cause burrs on the surface paper at the edge of the cut of the gypsum board, which requires secondary trimming. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a gypsum board cutting device for gypsum board production and processing, comprising a cutting table, a fixed frame fixedly connected to the top of the cutting table, two roller frames slidably connected to the top of the cutting table, screws rotatably connected to the side walls of the two roller frames, the outer walls of the two screws are threadedly connected to the inner wall of the cutting table, a fixed block fixedly connected to the top of the fixed frame, a motor fixedly connected to the side wall of the fixed block, a connecting rod 1 fixedly connected to the output end of the side wall of the motor, and a scribing assembly provided at the bottom of the fixed frame;

[0005] The cutting mechanism comprises a sliding block slidably connected to the inner wall of the fixed frame, a connecting rod 2 is rotatably connected at the side wall of the sliding block, the inner wall of the connecting rod 2 is rotatably connected to the outer wall of the connecting rod 1, the inner wall of the sliding block is fixedly connected to the fixing rod, a cutting knife is provided at the bottom of the fixed frame, the inner wall of the cutting knife is slidably connected to the outer wall of the fixing rod, a fixing plate 1 is fixedly connected to the side wall of the fixing rod, a connecting rod 1 is fixedly connected to the side wall of the cutting knife, a spring return rod 1 is fixedly connected to the side of the cutting knife away from the connecting rod 1, the outer wall of the spring return rod 1 is slidably connected to the inner wall of the fixing plate 1, a concave and convex block is fixedly connected to the side wall of the fixed frame, and the side wall of the concave and convex block is slidably connected to the side of the connecting rod 1 away from the cutting knife;

[0006] The clamping mechanism includes a connecting plate fixedly connected to the side wall of the sliding block, and a spring pressure plate is fixedly connected to the bottom of the connecting plate. A lifting assembly is provided on the inner wall of the cutting table. The staff places the gypsum board on the cutting table, and then drives the roller frame to move by rotating the screw, so that the roller frame contacts the gypsum board, so that the gypsum board can move horizontally, and then pushes the gypsum board to the position of the cutting knife, and adjusts the size to be cut. After the adjustment is completed, the motor is started to drive the connecting rod 1 to rotate, and the connecting rod 2 is rotated, and the connecting rod 2 is rotated around the output shaft of the motor as the center of the circle. When the connecting rod 2 rotates, it will push the sliding block up and down. When the connecting rod 1 rotates one circle, the sliding block completes a complete up and down reciprocating motion. When the sliding block moves downward, it will move the fixed rod downward, allowing the cutting knife to drop, so that the cutting knife contacts the gypsum board. At the same time, when the sliding block drops, it will also drive the connecting rod When the cutting knife is in contact with the gypsum board, the spring pressure plate will also come into contact with the gypsum board, squeezing the gypsum board to prevent the gypsum board from moving when being cut. When the cutting knife descends, it will also drive the connecting rod to descend and slide at the side wall of the concave and convex block. When the connecting rod moves from the concave position of the concave and convex block to the convex position, the connecting rod will be squeezed and move toward the fixed plate, driving the cutting knife to move, so that the spring return rod is squeezed and accumulates rebound force. When the connecting rod moves to the concave position of the concave and convex block, the cutting knife is returned to its position by the rebound force of the spring return rod. This reciprocating process makes the cutting knife squeeze the gypsum board and move horizontally at the same time to cut the gypsum board. When the cutting knife performs horizontal cutting, it has a smaller cutting force, which helps to reduce the tearing of the surface paper of the gypsum board and effectively prevents burrs from appearing after the surface paper of the gypsum board is cut.

[0007] Preferably, the marking assembly includes a sliding frame arranged at the bottom of the cutting knife, a plurality of cutting wheels are rotatably connected to the inner wall of the sliding frame, sliding rods are fixedly connected to the left and right sides of the sliding frame, and a bevel extrusion block is fixedly connected to the outer walls of the two sliding rods.

[0008] The camming mechanism is constructed so that when the camming tool is operating, the two cams will move upwards to move the tool away from the drive rails and away from the drive rails, thereby reducing the risk of damage to the tool train.

[0009] Preferably, the scribing assembly further comprises a spring ramp block fixedly connected to the side wall of the right sliding rod, the left and right sides of the cutting table are both slidably connected to connecting frames, and the inner walls of the two connecting frames are both slidably connected to the outer wall of the sliding rod;

[0010] Among them, the side walls of the connecting frame are fixedly connected to the side walls of the spring support block, and the side wall of the right connecting frame is fixedly connected with a second inclined extrusion block, and the inner wall of the cutting table is fixedly connected with two oil pipes. The inner walls of the two oil pipes are provided with hydraulic oil, which squeezes the surface paper of the gypsum board. When the sliding rod descends, it will squeeze the spring in the spring support block. At the same time, the sliding rod on the right side will also drive the spring inclined block to descend, so that the inclined surface of the spring inclined block contacts the inclined surface of the inclined extrusion block 2, so that the spring inclined block is squeezed, and the spring inclined block is brought close to the connecting frame, so that the sliding rod moves, driving the sliding frame to move horizontally, and allowing the cutting wheel to pre-cut the surface paper of the gypsum board.

[0011] The cam is fixedly mounted on the top of the two guide rails, and the two guide rails are connected to the hydraulic cylinder to move upwards, so that the hydraulic cylinder will not move downwards, and the hydraulic cylinder will not move downwards, thereby making the hydraulic cylinder move upwards and downwards.

[0012] Preferably, the jacking assembly includes two placement grooves provided on the inner wall of the cutting table, the inner walls of the two placement grooves are rotatably connected to a rotating frame, the inner walls of the two rotating frames are slidably connected to a jacking rod, and the side walls of the two spring support blocks are fixedly connected to a connecting rod 2. When the spring support block is away from the oil pipeline, it will also drive the connecting rod 2 to move. As the spring connecting rod 2 continues to move, the connecting rod 2 will contact the rotating frame, push the rotating frame to rotate, cause the rotating frame to tilt, and push the jacking rod to rise.

[0013] Preferably, the jacking assembly also includes a sliding plate slidably connected to the inner wall of the fixed frame, the bottom of the sliding plate is fixedly connected to two spring return rods three, the outer walls of the two spring return rods three are slidably connected to the inner wall of the cutting table, the top of the sliding plate is fixedly connected to a spring jacking plate, and the side walls of the fixed frame are fixedly connected to two fixed frames, which jack up the sliding plate and simultaneously drive the spring return rod three to move, allowing the spring return rod three to accumulate rebound force. When the sliding plate rises, it will also make the spring jacking plate rise, allowing the spring jacking plate to contact the bottom of the gypsum board, and slightly lift the surface paper of the cut at the bottom of the gypsum board.

[0014] The jacking assembly further comprises a sliding connection to the inner wall of the fixed frame, and the tops of the two extrusion plates are fixedly connected to two connecting rods three. A fixed plate three is provided on the left and right sides of the cutting table, and the side walls of the two fixed plates three are fixedly connected to the side walls of the jacking rod, and the side walls of the two fixed plates three are fixedly connected to the side walls of the connecting rod three. The two fixed frames are fixedly connected with a jet plate on one side near the cutting knife. When cutting is completed, the sliding block rises, so that the cutting knife rises, and at the same time, the connecting plate rises, the squeezing force on the piston rod one disappears, the rebound force of the spring return rod two is released, and the spring support block returns to its position, so that the connecting rod two is separated from the rotating frame, and the driving force on the rotating frame disappears, and the rebound force of the spring return rod three is released, so that the sliding plate returns to its position, the lifting rod returns to its position, and the lifting rod descends, driving the fixed plate three to descend, the connecting rod three to descend, and the squeezing plate descends to squeeze the gas in the fixed frame.

[0015] The present invention has the following beneficial effects:

[0016] (1) When the present invention is used, the staff places the gypsum board on the cutting table, and then drives the roller frame to move by rotating the screw, so that the roller frame contacts the gypsum board and the gypsum board can move horizontally, and then pushes the gypsum board to the position of the cutting knife, adjusts the size to be cut, and after the adjustment is completed, starts the motor to drive the connecting rod 1 to rotate, and drives the connecting rod 2 to rotate, and drives the connecting rod 2 to rotate around the output shaft of the motor as the center of the circle. When the connecting rod 2 rotates, it will push the sliding block to move up and down. After the connecting rod 1 rotates one circle, the sliding block completes a complete up and down reciprocating motion. When the sliding block moves downward, it will make the fixed rod move downward, and the cutting knife will drop, so that the cutting knife contacts the gypsum board. At the same time, when the sliding block drops, it will also drive the connecting plate and the spring pressure plate to drop. When the cutting knife contacts the gypsum board, the spring pressure plate When the connecting rod moves from the recessed position of the concave-convex block to the raised position, the connecting rod is squeezed and moves toward the fixed plate, driving the cutting knife to move, so that the spring return rod is squeezed and accumulates rebound force. When the connecting rod moves to the recessed position of the concave-convex block, the cutting knife is returned to its position by the rebound force of the spring return rod. This reciprocating process causes the cutting knife to squeeze the gypsum board while moving laterally to cut the gypsum board. When the cutting knife performs transverse cutting, it has a smaller cutting force, which helps to reduce the tearing of the surface paper of the gypsum board and effectively prevents burrs from appearing on the surface paper of the gypsum board after cutting.

[0017] (2) When the spring pressure plate of the present invention descends, it will also drive the inclined plate 1 to descend, so that the inclined surface of the inclined plate 1 contacts the inclined surface of the inclined plate 2, squeezes the inclined plate 2, and makes the inclined plate 2 move away from the cutting wheel, pulls the spring inclined rod to move, and makes the spring inclined rod accumulate rebound force, and at the same time, makes the inclined surface of the spring inclined rod contact the inclined surface of the inclined surface extrusion block 1, squeezes the inclined surface extrusion block 1, and makes the inclined surface extrusion block 1 descend, thereby driving the sliding rod to descend, and makes the sliding frame and the cutting wheel descend, so that the cutting wheel contacts the gypsum board and squeezes the surface paper of the gypsum board. When the sliding rod descends, it will squeeze the spring in the spring support block. At the same time, the sliding rod on the right side will also drive the spring inclined block to descend, so that the inclined surface of the spring inclined block contacts the inclined surface of the inclined surface extrusion block 2, so that the spring inclined block is squeezed, and the spring inclined block is close to the connecting frame, so that the sliding rod moves, drives the sliding frame to move horizontally, and makes the cutting wheel pre-cut the surface paper of the gypsum board. The hydraulic oil in the oil pipe is squeezed out, and the squeezed hydraulic oil pushes the piston rod to move, thereby allowing the spring support block to move away from the oil pipe, and driving the sliding frame and the cutting wheel to move through the sliding rod, so that the cutting wheel is away from the cutting knife, so that the cutting knife can smoothly descend and contact the gypsum board. At the same time, the spring support block will also drive the spring return rod second to move, allowing the spring return rod second to accumulate rebound force, and pre-cut the surface paper of the gypsum board to provide a cutting trajectory for the cutting knife, thereby reducing the extrusion force of the cutting knife on the gypsum board, and effectively preventing the cutting knife from squeezing the gypsum board, which may cause the gypsum near the cutting port of the gypsum board to crack, affecting the flatness of the cutting port.

[0018] (3) When the spring support block of the present invention is away from the oil pipeline, it will also drive the connecting rod 2 to move. As the spring connecting rod 2 continues to move, the connecting rod 2 will contact the rotating frame, push the rotating frame to rotate, and make the rotating frame tilt, push the lifting rod to rise, lift the sliding plate, and at the same time drive the spring return rod 3 to move, so that the spring return rod 3 accumulates rebound force. When the sliding plate rises, it will also make the spring lifting plate rise, so that the spring lifting plate contacts the bottom of the gypsum board, and slightly lift the surface paper of the cut at the bottom of the gypsum board. At this time, the cutting knife will also contact the surface paper at the bottom of the gypsum board. By lifting the surface paper at the bottom of the gypsum board, the contact pressure between the cutting knife and the bottom surface paper is increased, which makes it easier for the cutting knife to cut the bottom surface paper better, and effectively prevents the cutting knife from having insufficient contact pressure on the bottom surface paper of the gypsum board, which may make it difficult to completely penetrate the surface paper.

[0019] (4) When the cutting is completed, the sliding block of the present invention rises, causing the cutting knife to rise. At the same time, the connecting plate rises, the squeezing force on the piston rod 1 disappears, the rebound force of the spring return rod 2 is released, the spring support block returns to its position, and the connecting rod 2 is separated from the rotating frame. The driving force on the rotating frame disappears, the rebound force of the spring return rod 3 is released, the sliding plate returns to its position, the lifting rod returns to its position, the lifting rod descends, and the fixed plate 3 descends, causing the connecting rod 3 to descend, and the squeezing plate descends, squeezing the gas in the fixed frame. The squeezed gas is sprayed toward the cutting knife through the jet plate, and the dust of the gypsum board attached to the cutting knife is removed, so as to avoid the cutting knife from cutting frequently, resulting in excessive dust attached to the surface of the cutting knife, affecting the cutting effect.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For example 1, please refer to Figure 1-Figure 5 The present invention is a gypsum board cutting device for gypsum board production and processing, comprising a cutting table 1, a fixed frame 11 being fixedly connected to the top of the cutting table 1, two roller frames 12 being slidably connected to the top of the cutting table 1, screws 13 being rotatably connected to the side walls of the two roller frames 12, the outer walls of the two screws 13 being threadedly connected to the inner wall of the cutting table 1, a fixed block 14 being fixedly connected to the top of the fixed frame 11, a motor 15 being fixedly connected to the side wall of the fixed block 14, a connecting rod 16 being fixedly connected to the output end of the side wall of the motor 15, and a scribing assembly 4 being provided at the bottom of the fixed frame 11;

[0035] The cutting mechanism 2 includes a sliding block 21 slidably connected to the inner wall of the fixed frame 11, and a connecting rod 22 is rotatably connected to the side wall of the sliding block 21. The inner wall of the connecting rod 22 is rotatably connected to the outer wall of the connecting rod 16, and a fixing rod 23 is fixedly connected to the inner wall of the sliding block 21. A cutting knife 24 is provided at the bottom of the fixed frame 11, and the inner wall of the cutting knife 24 is slidably connected to the outer wall of the fixing rod 23. A fixing plate 231 is fixedly connected to the side wall of the fixing rod 23, and a connecting rod 241 is fixedly connected to the side wall of the cutting knife 24. A spring return rod 242 is fixedly connected to the side of the cutting knife 24 away from the connecting rod 241, and the outer wall of the spring return rod 242 is slidably connected to the inner wall of the fixing plate 231. A concave and convex block 25 is fixedly connected to the side wall of the fixed frame 11, and the side wall of the concave and convex block 25 is slidably connected to the side of the connecting rod 241 away from the cutting knife 24;

[0036] The pressing mechanism 3 includes a connecting plate 31 fixedly connected to the side wall of the sliding block 21, and a spring pressure plate 32 is fixedly connected to the bottom of the connecting plate 31. A lifting assembly 5 is provided at the inner wall of the cutting table 1. The staff places the gypsum board on the cutting table 1, and then drives the roller frame 12 to move by rotating the screw 13, so that the roller frame 12 contacts the gypsum board, so that the gypsum board can move horizontally, and then pushes the gypsum board to the position of the cutting knife 24 to adjust the size to be cut. After the adjustment is completed, the motor 15 is started to drive the connecting rod 16 to rotate, so that the connecting rod 22 rotates, and the connecting rod 22 rotates around the output shaft of the motor 15 as the center of the circle. When the connecting rod 22 rotates, it will push the sliding block 21 to move up and down. After the connecting rod 16 rotates one circle, the sliding block 21 completes a complete up and down reciprocating motion. When the sliding block 21 moves downward, the fixed rod 23 will move downward, allowing the cutting knife 24 to descend, so that the cutting knife 24 contacts the gypsum board. At the same time, when the sliding block 21 descends, it will also drive The connecting plate 31 and the spring pressure plate 32 descend. When the cutting knife 24 contacts the gypsum board, the spring pressure plate 32 will also contact the gypsum board to squeeze the gypsum board to prevent the gypsum board from moving when being cut. When the cutting knife 24 descends, it will also drive the connecting rod 1 241 to descend and slide on the side wall of the concave-convex block 25. When the connecting rod 1 241 moves from the concave position of the concave-convex block 25 to the convex position, the connecting rod 1 241 will be squeezed and move toward the fixing plate 1 231, driving the cutting knife 24 When the connecting rod 241 moves to the recessed position of the concave-convex block 25, the spring return rod 242 returns the cutting knife 24 to its original position through the rebound force of the spring return rod 242. This reciprocating motion allows the cutting knife 24 to squeeze the gypsum board while moving laterally to cut the gypsum board. When the cutting knife 24 performs transverse cutting, it has a smaller cutting force, which helps to reduce the tearing of the surface paper of the gypsum board and effectively prevents burrs from appearing on the surface paper of the gypsum board after cutting.

Two sliding grooves 47 are provided on the inner wall of the cutting table 1. The inner walls of the two sliding grooves 47 are slidably connected to spring support blocks 471. The inner walls of the two spring support blocks 471 are slidably connected to the outer wall of the sliding rod 44. When the spring pressure plate 32 descends, it also drives the inclined panel 1 43 to descend. , let the inclined surface of inclined panel 1 43 contact the inclined surface of inclined panel 2 431, squeeze inclined panel 2 431, let inclined panel 2 431 move away from the cutting wheel 42, pull the spring inclined rod 432 to move, let the spring inclined rod 432 accumulate rebound force, and at the same time, let the inclined surface of spring inclined rod 432 contact the inclined surface of inclined surface extrusion block 1 441, squeeze inclined surface extrusion block 1 441, let inclined surface extrusion block 1 441 descend, thereby driving the sliding rod 44 to descend, let the sliding frame 41 and the cutting wheel 42 descend, and make the cutting wheel 42 contact with the gypsum board.

[0039] The marking assembly 4 also includes a spring ramp block 473 fixedly connected to the side wall of the right sliding rod 44. The left and right sides of the cutting table 1 are both slidably connected to connecting frames 472.

At this time, the blocking force on the inclined extrusion block 1 441 disappears. The rebound force of the spring in the spring support block 471 will be released, allowing the sliding rod 44 to return to its position, so that the cutting wheel 42 is separated from the gypsum board. At this time, the fixed plate 2 45 that follows the connection plate 31 to descend will contact the piston rod 1 461, allowing the piston rod 1 461 to squeeze the hydraulic oil in the oil pipe 46. The squeezed hydraulic oil will push the piston rod 2 462 to move, thereby allowing the spring support block 471 to move away from the oil pipe 46, and drive the sliding frame 41 and the cutting wheel 42 to move through the sliding rod 44, so that the cutting wheel 42 is away from the cutting knife 24, allowing the cutting knife 24 to smoothly descend and contact the gypsum board.

When the cutting is completed, the sliding block 21 rises, so that The cutting knife 24 rises, and at the same time, the connecting plate 31 rises, the squeezing force on the piston rod 1 461 disappears, the rebound force of the spring return rod 2 475 is released, the spring support block 471 returns to its position, the connecting rod 2 513 is separated from the rotating frame 511, the driving force on the rotating frame 511 disappears, the rebound force of the spring return rod 3 521 is released, the sliding plate 52 returns to its position, the lifting rod 512 returns to its position, the lifting rod 512 descends, the fixed plate 3 54 descends, the connecting rod 3 552 descends, the squeezing plate 551 descends, and the gas in the fixed frame 55 is squeezed.

[0045] A specific application of this embodiment is as follows: when the present invention is used, the staff places the gypsum board on the cutting table 1, and then drives the roller frame 12 to move by rotating the screw 13, so that the roller frame 12 contacts the gypsum board, so that the gypsum board can move horizontally, and then pushes the gypsum board to the position of the cutting knife 24, adjusts the size to be cut, and after the adjustment is completed, starts the motor 15 to drive the connecting rod 16 to rotate, so that the connecting rod 22 rotates, and the connecting rod 22 rotates around the output shaft of the motor 15 as the center of the circle. When the connecting rod 22 rotates, it will push the sliding block 21 to move up and down. After the connecting rod 16 rotates one circle, the sliding block 21 completes a complete up and down reciprocating motion. When the sliding block 21 moves downward, it will make the fixed rod 23 move downward, so that the cutting knife 24 drops, so that the cutting knife 24 contacts the gypsum board. At the same time, when the sliding block 21 drops, it will also drive the connecting plate 31 and the spring pressure plate 32 to drop. When the cutting knife 24 contacts the gypsum board When the spring pressure plate 32 is in contact with the gypsum board, the spring pressure plate 32 will also come into contact with the gypsum board, squeezing the gypsum board to prevent the gypsum board from moving when being cut. When the cutting knife 24 descends, it will also drive the connecting rod 1 241 to descend and slide on the side wall of the concave-convex block 25. When the connecting rod 1 241 moves from the concave position of the concave-convex block 25 to the convex position, the connecting rod 1 241 will be squeezed and move toward the fixed plate 1 231, driving the cutting knife 24 to move, so that the spring return rod 1 242 is squeezed and accumulates rebound force. When the connecting rod 1 241 moves to the concave position of the concave-convex block 25, the rebound force of the spring return rod 1 242 allows the cutting knife 24 to return to its original position. This reciprocating process causes the cutting knife 24 to squeeze the gypsum board and move horizontally at the same time to cut the gypsum board. When the cutting knife 24 performs horizontal cutting, it has a smaller cutting force, which helps to reduce the tearing of the surface paper of the gypsum board and effectively prevents burrs from appearing on the surface paper of the gypsum board after cutting.

[0046] Secondly, when the spring pressure plate 32 descends, it also drives the inclined plate 1 43 to descend, so that the inclined surface of the inclined plate 1 43 contacts the inclined surface of the inclined plate 2 431, squeezes the inclined plate 2 431, and makes the inclined plate 2 431 away from the cutting wheel 42, pulls the spring inclined surface rod 432 to move, and makes the spring inclined surface rod 432 accumulate rebound force. At the same time, the inclined surface of the spring inclined surface rod 432 contacts the inclined surface of the inclined surface extrusion block 1 441, squeezes the inclined surface extrusion block 1 441, and makes the inclined surface extrusion block 1 441 descend, thereby driving the sliding rod 44 to descend, so that the sliding frame 41 and the cutting wheel 42 descends, causing the cutting wheel 42 to contact the gypsum board and squeeze the surface paper of the gypsum board. When the sliding rod 44 descends, it squeezes the spring in the spring support block 471. At the same time, the sliding rod 44 on the right side also drives the spring inclined surface block 473 to descend, allowing the inclined surface of the spring inclined surface block 473 to contact the inclined surface of the inclined surface squeezing block 2 474, so that the spring inclined surface block 473 is squeezed, and the spring inclined surface block 473 is close to the connecting frame 472, so that the sliding rod 44 moves, driving the sliding frame 41 to move horizontally, so that the cutting wheel 42 pre-cuts the surface paper of the gypsum board. As the spring presses The continuous descent of the plate 32 will separate the spring inclined rod 432 from the inclined extrusion block 1 441. At this time, the blocking force on the inclined extrusion block 1 441 disappears, and the rebound force of the spring in the spring support block 471 is released, allowing the sliding rod 44 to return to its original position, so that the cutting wheel 42 is separated from the gypsum board. At this time, the fixed plate 2 45 that follows the connection plate 31 to descend will contact the piston rod 1 461, allowing the piston rod 1 461 to squeeze the hydraulic oil in the oil pipe 46. The squeezed hydraulic oil will push the piston rod 2 462 to move, thereby allowing the spring support block 471 to move away from the oil pipe 46. The movable rod 44 drives the sliding frame 41 and the cutting wheel 42 to move, so that the cutting wheel 42 moves away from the cutting knife 24, allowing the cutting knife 24 to smoothly descend and contact the gypsum board. At the same time, the spring support block 471 also drives the spring return rod 275 to move, so that the spring return rod 275 accumulates a rebound force, and pre-cuts the surface paper of the gypsum board to provide a cutting track for the cutting knife 24, thereby reducing the squeezing force of the cutting knife 24 on the gypsum board, and effectively preventing the gypsum near the cut of the gypsum board from cracking when the cutting knife 24 squeezes the gypsum board, thereby affecting the flatness of the cut.

[0047] When the spring support block 471 is away from the oil pipe 46, the second connecting rod 513 is driven to move. As the spring connecting rod 513 continues to move, the second connecting rod 513 contacts the rotating frame 511, pushing the rotating frame 511 to rotate, causing the rotating frame 511 to tilt, pushing the lifting rod 512 to rise, and lifting the sliding plate 52. At the same time, it drives the spring return rod 3 521 to move, allowing the spring return rod 3 521 to accumulate rebound force. When the sliding plate 52 rises, it also causes the spring lifting plate 53 to rise, allowing the spring lifting plate 53 to contact the bottom of the gypsum board, slightly lifting the surface paper of the cutting opening at the bottom of the gypsum board. At this time, the cutting knife 24 will also contact the surface paper at the bottom of the gypsum board, by lifting the surface paper at the bottom of the gypsum board, increasing the contact pressure between the cutting knife 24 and the bottom surface paper, making it easier for the cutting knife 24 to cut the bottom surface paper, and effectively preventing the cutting knife 24 from having insufficient contact pressure on the surface paper at the bottom of the gypsum board, which may make it difficult to completely penetrate the surface paper.

[0048] The second spring 521 of the spring return rod 521 is released, and the sliding plate 52 is returned to its original position, so that the lifting rod 512 is returned to its original position, and the lifting rod 512 is lowered, driving the fixed plate 3 54 to descend, so that the connecting rod 3 552 is lowered, and the extrusion plate 551 is lowered, squeezing the gas in the fixed frame 55. The squeezed gas is ejected toward the cutting knife 24 through the jet plate 553, and the dust of the gypsum board attached to the cutting knife 24 is removed, so as to avoid the cutting knife 24 from cutting frequently, resulting in excessive dust attached to the surface of the cutting knife 24, affecting the cutting effect.
