The device includes a chassis with two motors fixedly connected to the top. The output shafts of the two motors are fixedly connected to drive rods. Before use, the gypsum board is placed on top of a conveyor belt. The conveyor belt drives the gypsum board to contact the outer wall of a saw blade.

Description

Technical Field

[0001] This invention relates to the field of gypsum board cutting equipment technology, specifically to a gypsum board cutting device and its cutting method. Background Technology

[0002] Gypsum board is a lightweight board made from building gypsum as the main raw material through a series of processes. It has the advantages of light weight and high strength. In order to meet construction needs, gypsum board needs to be cut, such as different sizes of walls and ceilings. Cut gypsum board can be more easily installed and spliced ​​to meet various architectural design requirements.

[0003] When cutting gypsum board, due to the material properties of gypsum itself, dust generated by the gypsum will be directly sprayed out when the gypsum board comes into contact with the saw blade, causing large-scale pollution of the processing environment. In order to address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a gypsum board cutting device, including a chassis, two motors fixedly connected to the top of the chassis, drive rods fixedly connected to the output shafts of the two motors, and a conveyor belt rotatably connected to the outer wall of the two drive rods;

[0005] The extrusion mechanism includes a support frame fixedly connected to the top of the chassis. An inclined plate is fixedly connected to one end of the support frame away from the chassis. A fixed rod is fixedly connected to the top of the chassis. Several rollers are rotatably connected to the bottom of the fixed rod. A cutting blade is fixedly connected to the side wall of the fixed rod.

[0006] The cutting mechanism includes a housing fixedly connected to the top of the chassis. A partition is fixedly connected to the inner wall of the housing, and a discharge pipe is connected through the inner wall of the partition. A rotating column is rotatably connected to the side wall of the discharge pipe. A transmission belt is fitted onto the outer wall of the rotating column, and a gear is fixedly connected to the outer wall of the rotating column. A rotating rod is rotatably connected to the side wall of the discharge pipe, and toothed grooves are formed on the side wall of the rotating rod. A saw blade is fixedly connected to the outer wall of the rotating rod. A collecting assembly is fixedly connected to the inner wall of the housing. Utilizing the hard and brittle nature of gypsum board, the equipment is equipped with an extrusion mechanism and a cutting mechanism. Before use, the gypsum board is placed on top of the conveyor belt, and then the motor power is turned on. At this time, the motor forces the conveyor belt along the outer wall of the inclined plate via the drive rod. During the sliding process, the conveyor belt drives the plasterboard into contact with the outer wall of the saw blade. As the drive rod rotates, it drives the rotating column to rotate in the same direction via the transmission belt. The rotating column, through gear one and its tooth marks, drives the rotating rod and saw blade to rotate in the opposite direction. At this time, the saw blade cuts the bottom of the plasterboard, creating a cutting line. As the conveyor belt continues to move, influenced by the inward tilt of the two inclined panels, the bottom of the plasterboard gradually becomes hollowed out as it follows the conveyor belt. After the top of the plasterboard contacts the outer wall of the roller, the roller, influenced by the downward tilt of the fixed rod, applies pressure to the top of the plasterboard, forcing it to fold downwards along the bottom cutting line, presenting a shape like... Figure 6 In the G state, the conveyor belt continues to move the broken plasterboard, and the cutting blade will cut the crack in the plasterboard to remove the paper material on the outer wall of the plasterboard. Through the application of the above components, the cutting area is reduced, and finally the plasterboard is broken by applying pressure, which greatly reduces the total amount of dust generated during plaster cutting.

[0007] Preferably, the collection assembly further includes a dust baffle plate fixedly connected to the inner wall of the housing, a second gear rotatably connected to the inner wall of the housing, and a first inclined gear fixedly connected to the side wall of the second gear.

[0008] Preferably, the collection assembly further includes a fixed bracket fixedly connected to the inner wall of the housing, a rotating tube rotatably connected to the inner wall of the fixed bracket, and an installation box connected through the bottom of the rotating tube.

[0009] Preferably, the collection component also includes a second inclined gear fixedly connected to the top of the rotating tube, four fan blades fixedly connected to the side wall of the mounting box, an inclined plate fixedly connected to the inner wall of the discharge pipe, and a cleaning component fixedly connected to the inner wall of the mounting box. Utilizing the characteristics of the saw blade cutting the bottom of the gypsum board, a cutting mechanism and a collection component are set inside the equipment. When the first gear rotates, the first gear drives the second inclined gear to rotate through the second gear and the first inclined gear. The second inclined gear drives the mounting box and the fan blades at the bottom to rotate through the rotating tube, causing the fan blades to generate a downward suction force. During this process, most of the gypsum powder produced by the saw blade cutting will enter the bottom of the outer casing through the discharge pipe along the inner wall of the inclined plate.

[0010] Preferably, the cleaning component includes a counterweight block slidably connected to the side wall of the fan blade, a hydraulic telescopic rod fixedly connected to the side wall of the counterweight block, and an L-shaped tube penetrating the inner wall of the mounting box. The end of the hydraulic telescopic rod away from the counterweight block is penetrating the side wall of the L-shaped tube. As the gypsum board is driven by the conveyor belt, it completely covers the top of the cutting mechanism. At this time, the dust baffle, the bottom of the gypsum board, and the partition box restrict the fine particles generated by cutting, making it difficult for them to drift to the surroundings. At this time, the mounting box at the bottom and the fan blade generate downward airflow, which forces most of the dust to flow downward through the discharge pipe and various gaps. Through the application of the above components, most of the dust generated during saw blade cutting is collected, reducing the amount of dust flowing outward.

[0011] Preferably, the cleaning component further includes a piston block slidably connected to the inner wall of the L-shaped tube. A linkage rod is fixedly connected to the top of the piston block, a ring is fixedly connected to the top of the linkage rod, and a spring is fixedly connected to the top of the ring. The end of the spring away from the ring is fixedly connected to the inner wall of the helical gear two. Utilizing the centrifugal force generated by the rotation of the fan blades driven by the aforementioned mounting box, a cleaning component is installed inside the equipment. As the rotation speed of the mounting box continuously increases, the centrifugal force on the counterweight also increases synchronously. During this process, the counterweight will move outward along the outer wall of the fan blades. During the displacement of the counterweight, it will scrape and clean the outer wall of the fan blades. When moving outward, the counterweight drives the hydraulic telescopic rod to extend outward synchronously, allowing the liquid inside the L-shaped tube to enter the hydraulic telescopic rod. This forces the piston block to drive the linkage rod to slide downward along the inner wall of the L-shaped tube. When the linkage rod drives the ring downward, it forces the spring to deform and accumulate mechanical power. After the equipment completes the cutting, the motor stops running, and the spring releases the mechanical power, which drives the piston block to reset through the linkage rod. The piston block then drives the counterweight to reset along the inner wall of the fan blade. After the equipment stops running, the counterweight will clean the outer wall of the fan blade again. Through the application of the above components, it is effectively prevented that dust particles adhere to the outer wall of the fan blade, affecting the efficiency of the fan blade in driving airflow.

[0012] Preferably, the outer wall of the second helical gear meshes with the outer wall of the first helical gear, the outer wall of the second gear meshes with the outer wall of the first gear, the outer wall of the first gear meshes with the inner wall of the toothed groove, the end of the transmission belt away from the rotating column is rotatably connected to the outer wall of the drive rod, and the outer wall of the inclined plate is slidably connected to the inner wall of the transmission belt. Utilizing the characteristic that the aforementioned multiple counterweights drive the piston block to slide up and down along the inner wall of the L-shaped tube, a ring is set inside the equipment. If a large gypsum board particle is adhered to the outer wall of one of the fan blades, the corresponding counterweight will have difficulty moving outward. When the obstructed counterweight is unable to move outward, the corresponding piston block also stops moving on the inner wall of the L-shaped tube. The obstructed piston block will restrict the linkage rod from continuing to move downward, and the obstructed linkage rod will force the ring to stop running. The stopped ring will restrict the operation of the remaining counterweights. Through the application of the above components, it is ensured that the speed and length of the counterweights moving laterally on the corresponding outer wall of the fan blade are equal, avoiding unequal positions of the counterweights, which would cause the rotation center of gravity of the fan blade to shift and affect the exhaust effect of the fan blade.

[0013] A cutting method for a gypsum board cutting device includes the following steps:

[0014] S1: Place the board material;

[0015] S2: Power on;

[0016] S3: Begin cutting.

[0017] The present invention has the following beneficial effects:

[0018] (1) This invention utilizes the hard and brittle characteristics of gypsum board. An extrusion mechanism and a cutting mechanism are installed inside the equipment. Before use, the gypsum board is placed on top of the conveyor belt, and then the motor power is turned on. At this time, the motor forces the conveyor belt to slide along the outer wall of the inclined panel through the drive rod. During the operation of the conveyor belt, the conveyor belt causes the gypsum board to contact the outer wall of the saw blade. When the drive rod rotates, the drive rod drives the rotating column to rotate in the same direction through the transmission belt. The rotating column drives the rotating rod and the saw blade to rotate in the opposite direction through gear one and tooth marks. At this time, the saw blade will cut the bottom of the gypsum board, creating a cutting line at the bottom. As the conveyor belt continues to move, influenced by the inward tilt of the two inclined panels, the bottom of the gypsum board will gradually become hollow as it moves with the conveyor belt. After the top of the gypsum board contacts the outer wall of the roller, the roller, influenced by the downward tilt of the fixed rod, will apply pressure to the top of the gypsum board, forcing the gypsum board to fold downwards with the bottom cutting line as the center line, presenting as... Figure 6 In the G state, the conveyor belt continues to move the broken plasterboard, and the cutting blade will cut the crack in the plasterboard to remove the paper material on the outer wall of the plasterboard. Through the application of the above components, the cutting area is reduced, and finally the plasterboard is broken by applying pressure, which greatly reduces the total amount of dust generated during plaster cutting.

[0019] (2) This invention utilizes the characteristics of the saw blade cutting the bottom of the gypsum board. A cutting mechanism and a collection component are installed inside the equipment. When gear one rotates, gear one drives gear two through gear two and inclined gear one to rotate. Inclined gear two drives the mounting box and fan blades at the bottom to rotate through the rotating tube, causing the fan blades to generate a downward suction force. During this process, most of the gypsum powder generated by the saw blade cutting will enter the bottom of the outer casing through the discharge pipe along the inner wall of the inclined plate. Furthermore, because the gypsum board is completely covered by the top of the cutting mechanism under the drive of the conveyor belt, the dust baffle, the bottom of the gypsum board, and the partition box restrict the fine particles generated by cutting, making it difficult for them to disperse. At this time, the downward airflow generated by the mounting box and fan blades at the bottom forces most of the dust to flow downwards through the discharge pipe and various gaps. Through the application of the above components, most of the dust generated during saw blade cutting is collected, reducing the amount of dust flowing outwards.

[0020] (3) This invention utilizes the centrifugal force generated by the rotation of the fan blades driven by the above-mentioned mounting box. A cleaning component is installed inside the equipment. As the rotation speed of the mounting box increases, the centrifugal force on the counterweight also increases synchronously. During this process, the counterweight will move outward along the outer wall of the fan blade. During the displacement of the counterweight, the outer wall of the fan blade will be scraped and cleaned. When the counterweight moves outward, the counterweight drives the hydraulic telescopic rod to extend outward synchronously, allowing the liquid inside the L-shaped tube to enter the hydraulic telescopic rod. This forces the piston block to drive the linkage rod to slide downward along the inner wall of the L-shaped tube. When the linkage rod drives the ring to move downward, it forces the spring to deform and accumulate mechanical power. After the equipment completes the cutting, the motor stops running, and the spring releases the mechanical power. The linkage rod drives the piston block to reset, and the piston block drives the counterweight to reset along the inner wall of the fan blade. After the equipment stops running, the counterweight will clean the outer wall of the fan blade again. Through the application of the above components, dust particles are effectively prevented from adhering to the outer wall of the fan blade, affecting the efficiency of the fan blade in driving airflow.

[0021] (4) This invention utilizes the feature that the above-mentioned multiple counterweights drive the piston block to slide up and down along the inner wall of the L-shaped tube. A ring is set inside the equipment. If a large gypsum board particle is stuck to the outer wall of one of the fan blades, the corresponding counterweight will have difficulty moving outward. When the obstructed counterweight has difficulty moving outward, the corresponding piston block will also stop moving on the inner wall of the L-shaped tube. The obstructed piston block will restrict the linkage rod from continuing to move downward, and the obstructed linkage rod will force the ring to stop running. The stopped ring will restrict the operation of the other counterweights. Through the application of the above components, the speed and length of the counterweights moving laterally on the corresponding outer wall of the fan blade are equal, avoiding the uneven position of the counterweights, which would cause the rotation center of gravity of the fan blade to shift and affect the exhaust effect of the fan blade.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1 - Figure 6 The present invention is a gypsum board cutting device, including a chassis 1, two motors 11 are fixedly connected to the top of the chassis 1, the output shafts of the two motors 11 are fixedly connected to drive rods 12, and a conveyor belt 13 is rotatably connected to the outer wall of the two drive rods 12.

[0038] The extrusion mechanism 2 includes a support frame 21 fixedly connected to the top of the chassis 1. An inclined plate 22 is fixedly connected to one end of the support frame 21 away from the chassis 1. A fixed rod 23 is fixedly connected to the top of the chassis 1. Several rollers 25 are rotatably connected to the bottom of the fixed rod 23. A cutting blade 24 is fixedly connected to the side wall of the fixed rod 23.

[0039] The cutting mechanism 3 includes a housing 31 fixedly connected to the top of the chassis 1. A partition 32 is fixedly connected to the inner wall of the housing 31. A discharge pipe 39 is connected through the inner wall of the partition 32. A rotating column 33 is rotatably connected to the side wall of the discharge pipe 39. A transmission belt 34 is sleeved on the outer wall of the rotating column 33. A gear 35 is fixedly connected to the outer wall of the rotating column 33. A rotating rod 36 is rotatably connected to the side wall of the discharge pipe 39. Tooth marks 37 are formed on the side wall of the rotating rod 36. A saw blade 38 is fixedly connected to the outer wall of the rotating rod 36. A collecting assembly 4 is fixedly connected to the inner wall of the housing 31. Taking advantage of the hard and brittle nature of gypsum board, an extrusion mechanism 2 and a cutting mechanism 3 are set inside the equipment. Before use, the gypsum board is placed on top of the conveyor belt 13. Then, the power supply of the motor 11 is turned on. At this time, the motor 11 forces the conveyor belt 13 along the conveyor belt 13 via the drive rod 12. The outer wall of the inclined panel 22 slides. During the operation of the conveyor belt 13, the conveyor belt 13 drives the plasterboard to contact the outer wall of the saw blade 38. When the drive rod 12 rotates, the drive rod 12 drives the rotating column 33 to rotate in the same direction through the transmission belt 34. The rotating column 33 drives the rotating rod 36 and the saw blade 38 to rotate in the opposite direction through the gear 35 and tooth mark 37. At this time, the saw blade 38 will cut the bottom of the plasterboard, so that a cutting line appears at the bottom of the plasterboard. As the conveyor belt 13 continues to move, affected by the inward tilt of the two inclined panels 22, the bottom of the plasterboard will gradually become hollow as the plasterboard moves with the conveyor belt 13. After the top of the plasterboard contacts the outer wall of the roller 25, the roller 25 will apply pressure to the top of the plasterboard due to the downward tilt of the fixed rod 23, forcing the plasterboard to fold downward with the bottom cutting line as the center line, presenting as Figure 6 In the middle G state, the conveyor belt 13 continues to move the broken plasterboard, and the cutting blade 24 cuts the crack in the plasterboard to remove the paper material on the outer wall of the plasterboard. Through the application of the above components, the cutting area is reduced, and finally the plasterboard is broken by applying pressure, which greatly reduces the total amount of dust generated during plaster cutting.

[0040] Example 2, please refer to Figure 7 - Figure 11 The present invention is a gypsum board cutting device. Based on the first embodiment, the collecting component 4 further includes a dust baffle 41 fixedly connected to the inner wall of the outer shell 31, a gear 42 rotatably connected to the inner wall of the outer shell 31, and a helical gear 43 fixedly connected to the side wall of the gear 42.

[0041] The collection component 4 also includes a fixed bracket 44 fixedly connected to the inner wall of the housing 31, a rotating tube 45 rotatably connected to the inner wall of the fixed bracket 44, and a mounting box 47 connected through the bottom of the rotating tube 45.

[0042] The collecting component 4 also includes a second inclined gear 46 fixedly connected to the top of the rotating tube 45, four fan blades 48 fixedly connected to the side wall of the mounting box 47, an inclined plate 49 fixedly connected to the inner wall of the discharge pipe 39, and a cleaning component 5 fixedly connected to the inner wall of the mounting box 47. Taking advantage of the characteristics of the saw blade 38 in cutting the bottom of the gypsum board, a cutting mechanism 3 and a collecting component 4 are set inside the equipment. When the first gear 35 rotates, the first gear 35 drives the second inclined gear 46 to rotate through the second gear 42 and the first inclined gear 43. The second inclined gear 46 drives the mounting box 47 and the fan blades 48 at the bottom to rotate through the rotating tube 45, so that the fan blades 48 generate a downward suction force. During this process, most of the gypsum powder produced by the saw blade 38 will enter the bottom of the outer casing 31 through the discharge pipe 39 along the inner wall of the inclined plate 49.

[0043] The cleaning component 5 includes a counterweight 51 slidably connected to the side wall of the blade 48. A hydraulic telescopic rod 52 is fixedly connected to the side wall of the counterweight 51. An L-shaped tube 53 is connected through the inner wall of the mounting box 47. The end of the hydraulic telescopic rod 52 away from the counterweight 51 is connected through the side wall of the L-shaped tube 53. As the gypsum board is driven by the conveyor belt 13, it completely covers the top of the cutting mechanism 3. At this time, the dust baffle 41, the bottom of the gypsum board and the partition box 32 restrict the fine particles generated by cutting, making it difficult for them to drift around. At this time, the mounting box 47 at the bottom and the blade 48 generate downward airflow, which will force most of the dust to flow downward through the discharge pipe 39 and various gaps. Through the application of the above components, most of the dust generated when the saw blade 38 is cutting is collected, reducing the amount of dust flowing out.

[0044] The cleaning component 5 also includes a piston block 54 slidably connected to the inner wall of the L-shaped tube 53. A linkage rod 55 is fixedly connected to the top of the piston block 54, and a ring 56 is fixedly connected to the top of the linkage rod 55. A spring 57 is fixedly connected to the top of the ring 56, and the end of the spring 57 away from the ring 56 is fixedly connected to the inner wall of the helical gear 46. Utilizing the centrifugal force generated by the rotation of the fan blade 48 driven by the mounting box 47, the cleaning component 5 is installed inside the equipment. As the rotation speed of the mounting box 47 increases, the centrifugal force on the counterweight 51 also increases synchronously. During this process, the counterweight 51 will move outward along the outer wall of the fan blade 48. During the displacement of the counterweight 51, it will scrape and clean the outer wall of the fan blade 48. When in motion, the counterweight 51 drives the hydraulic telescopic rod 52 to extend outward synchronously, allowing the liquid inside the L-shaped tube 53 to enter the hydraulic telescopic rod 52. This forces the piston block 54 to drive the linkage rod 55 to slide downward along the inner wall of the L-shaped tube 53. When the linkage rod 55 drives the ring 56 to move downward, it forces the spring 57 to deform and accumulate mechanical power. After the equipment completes the cutting, the motor 11 stops running, and the spring 57 releases the mechanical power, which drives the piston block 54 to reset through the linkage rod 55. The piston block 54 then drives the counterweight 51 to reset along the inner wall of the fan blade 48. After the equipment stops running, the counterweight 51 will clean the outer wall of the fan blade 48 again. Through the application of the above components, it is effectively prevented that dust particles adhere to the outer wall of the fan blade 48, affecting the efficiency of the fan blade 48 in driving airflow.

[0045] The outer wall of the second helical gear 46 meshes with the outer wall of the first helical gear 43; the outer wall of the second gear 42 meshes with the outer wall of the first gear 35; the outer wall of the first gear 35 meshes with the inner wall of the tooth mark 37; the end of the transmission belt 34 away from the rotating column 33 is rotatably connected to the outer wall of the drive rod 12; the outer wall of the inclined plate 22 is slidably connected to the inner wall of the transmission belt 13. Utilizing the characteristic that the aforementioned multiple counterweights 51 drive the piston block 54 to slide up and down along the inner wall of the L-shaped tube 53, a ring 56 is provided inside the equipment. If a large particle of gypsum board adheres to the outer wall of one of the fan blades 48, the corresponding counterweight... When the counterweight 51 is unable to move outward, the corresponding piston block 54 also stops moving on the inner wall of the L-shaped tube 53. The obstructed piston block 54 will restrict the linkage rod 55 from moving downward, and the obstructed linkage rod 55 will force the ring 56 to stop running. The stopped ring 56 will restrict the operation of the remaining counterweights 51. Through the application of the above components, the speed and length of the counterweight 51 moving laterally on the outer wall of the corresponding fan blade 48 are ensured to be equal, avoiding the uneven position of the counterweights 51, which would cause the rotation center of gravity of the fan blade 48 to shift and affect the exhaust effect of the fan blade 48.

[0046] The cutting method of this gypsum board cutting equipment includes the following steps:

[0047] S1: Place the board material;

[0048] S2: Power on;

[0049] S3: Begin cutting.

[0050] A specific application of this embodiment is as follows: Before use, the plasterboard is placed on top of the conveyor belt 13, and then the power supply of the motor 11 is turned on. At this time, the motor 11 forces the conveyor belt 13 to slide along the outer wall of the inclined panel 22 through the drive rod 12. During the operation of the conveyor belt 13, the conveyor belt 13 drives the plasterboard to contact the outer wall of the saw blade 38. When the drive rod 12 rotates, the drive rod 12 drives the rotating column 33 to rotate in the same direction through the transmission belt 34. The rotating column 33 drives the rotating rod 36 and the saw blade 38 through the gear 35 and the tooth mark 37. Saw blade 38 rotates in the opposite direction, cutting the bottom of the plasterboard and creating a cutting line. As the conveyor belt 13 continues to move, influenced by the inward tilt of the two inclined panels 22, the bottom of the plasterboard gradually becomes hollow as it follows the conveyor belt 13. After the top of the plasterboard contacts the outer wall of the roller 25, the roller 25, influenced by the downward tilt of the fixing rod 23, applies pressure to the top of the plasterboard, forcing it to fold downwards along the bottom cutting line, resulting in a shape resembling... Figure 6 In the middle G state, the conveyor belt 13 continues to move the broken plasterboard, and the cutting blade 24 cuts the crack in the plasterboard to remove the paper material on the outer wall of the plasterboard. Through the application of the above components, the cutting area is reduced, and finally the plasterboard is broken by applying pressure, which greatly reduces the total amount of dust generated during plaster cutting.

[0051] Utilizing the cutting characteristics of the saw blade 38 at the bottom of the gypsum board, a cutting mechanism 3 and a collecting assembly 4 are installed inside the equipment. When gear 35 rotates, gear 35 drives inclined gear 46 to rotate via gear 42 and inclined gear 43. Inclined gear 46 drives the mounting box 47 at the bottom and the fan blade 48 to rotate via the rotating tube 45, causing the fan blade 48 to generate a downward suction force. During this process, most of the gypsum powder produced by the saw blade 38 will enter the outer wall along the inclined plate 49 through the discharge pipe 39. The bottom of shell 31; Furthermore, because the gypsum board, driven by the conveyor belt 13, completely covers the top of the cutting mechanism 3, the dust baffle 41, the bottom of the gypsum board, and the partition box 32 restrict the fine particles generated during cutting, making it difficult for them to disperse. At the same time, the mounting box 47 at the bottom and the fan blades 48 generate downward airflow, forcing most of the dust to flow downwards through the discharge pipe 39 and various gaps. Through the application of these components, most of the dust generated during saw blade 38 cutting is collected, reducing the amount of dust flowing outwards.

[0052] Utilizing the centrifugal force generated by the rotation of the fan blade 48 driven by the mounting box 47, a cleaning component 5 is installed inside the equipment. As the rotation speed of the mounting box 47 increases, the centrifugal force on the counterweight 51 also increases synchronously. During this process, the counterweight 51 moves outward along the outer wall of the fan blade 48, scraping and cleaning the outer wall of the fan blade 48 during its displacement. As the counterweight 51 moves outward, it drives the hydraulic telescopic rod 52 to extend outward synchronously, allowing the liquid inside the L-shaped tube 53 to enter the hydraulic telescopic rod 52, forcing the piston block 54 to drive the linkage. As rod 55 slides downward along the inner wall of L-shaped tube 53, the linkage rod 55 drives the ring 56 to move downward, forcing the spring 57 to deform and accumulate mechanical power. After the equipment completes the cutting, the motor 11 stops running, and the spring 57 releases the mechanical power, which drives the piston block 54 to reset through the linkage rod 55. The piston block 54 drives the counterweight block 51 to reset along the inner wall of the fan blade 48. After the equipment stops running, the counterweight block 51 will clean the outer wall of the fan blade 48 again. Through the application of the above components, dust particles are effectively prevented from adhering to the outer wall of the fan blade 48, affecting the efficiency of the fan blade 48 in driving airflow.

[0053] Utilizing the characteristic that the aforementioned multiple counterweights 51 drive the piston block 54 to slide up and down along the inner wall of the L-shaped tube 53, a circular ring 56 is provided inside the equipment. If large gypsum board particles are adhered to the outer wall of one of the fan blades 48, the corresponding counterweight 51 will have difficulty moving outward. When the obstructed counterweight 51 cannot move outward, the corresponding piston block 54 will also stop moving on the inner wall of the L-shaped tube 53. The obstructed piston block 54 will restrict the linkage rod 55 from continuing to move downward, and the obstructed linkage rod 55 will force the circular ring 56 to stop running. The stopped circular ring 56 will restrict the operation of the remaining counterweights 51. Through the application of the above components, it is ensured that the speed and length of the counterweight 51 moving laterally on the outer wall of the corresponding fan blade 48 are equal, avoiding unequal positions of the counterweights 51, which would cause the rotation center of gravity of the fan blade 48 to shift and affect the exhaust effect of the fan blade 48.
