Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board cutting equipment, and specifically relates to a gypsum board cutting equipment and a cutting method thereof. Background Art

[0002] Gypsum board is a lightweight board mainly made of building gypsum through a series of processes, and has advantages such as light weight and high strength. Among them, in order to meet the construction requirements, it is necessary to cut the gypsum board, such as for walls and ceilings of different sizes. The cut gypsum board can be more easily installed and spliced to meet various requirements of architectural design.

[0003] When cutting the gypsum board, affected by the material of the gypsum itself, when the gypsum board contacts the saw blade, the dust generated by the gypsum will directly spray outwards, causing large-area pollution of the processing environment. In view of 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 equipment, including a chassis. Two motors are fixedly connected to the top of the chassis. The output shafts of the two motors are fixedly connected to driving rods. A conveyor belt is rotatably connected to the outer walls of the two driving rods.

[0005] An extrusion mechanism, the extrusion mechanism includes a support frame fixedly connected to the top of the chassis. One end of the support frame away from the chassis is fixedly connected to an inclined panel. A fixed rod is fixedly connected to the top of the chassis. A plurality of rollers are rotatably connected to the bottom of the fixed rod. A cutting knife is fixedly connected to the side wall of the fixed rod.

[0006] Cutting mechanism, the cutting mechanism includes a housing fixedly connected to the top of the chassis. There is a partition box fixedly connected to the inner wall of the housing. A discharge pipe is connected through the inner wall of the partition box. A rotating column is rotatably connected to the side wall of the discharge pipe. A transmission belt is sleeved on the outer wall of the rotating column. A first 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. Tooth marks are provided on the side wall of the rotating rod. A saw blade is fixedly connected to the outer wall of the rotating rod. A collection component is fixedly connected to the inner wall of the housing. Utilizing the characteristics of gypsum board being hard and brittle, an extrusion mechanism and a cutting mechanism are provided inside the equipment. Before use, place the gypsum board on the top of the conveyor belt, and then turn on the power of the motor. At this time, the motor forces the conveyor belt to slide along the outer wall of the inclined panel through the driving rod. During the operation of the conveyor belt, the conveyor belt drives the gypsum board to contact the outer wall of the saw blade. When the driving rod rotates, the driving rod drives the rotating column to rotate in the same direction through the transmission belt, and the rotating column drives the rotating rod and the saw blade to rotate in the reverse direction through the first gear and the tooth marks. At this time, the saw blade will cut the bottom of the gypsum, making a cut line at the bottom of the gypsum. As the conveyor belt continues to move, affected by the inward inclination of the two inclined panels, when the gypsum board moves with the conveyor belt, the bottom of the gypsum board will gradually become hollow, and after the top of the gypsum contacts the outer wall of the roller, affected by the downward inclination of the fixed rod, the roller will apply a pressure to the top of the gypsum board, forcing the gypsum board to fold downward with the cut line at the bottom as the center line, presenting a state as shown in Figure 6 G in the figure. The conveyor belt drives the broken gypsum board to continue moving, and the cutting knife will cut the crack of the gypsum board to remove the paper material on the outer wall of the gypsum board. Through the application of the above components, the cutting area is reduced, and finally the gypsum board is broken by applying pressure, greatly reducing the total amount of dust generated during gypsum cutting.

[0007] Preferably, the collection component further includes a dust baffle fixedly connected to the inner wall of the housing. A second gear is rotatably connected to the inner wall of the housing. A first bevel gear is fixedly connected to the side wall of the second gear.

[0008] Preferably, the collection component further includes a fixed bracket fixedly connected to the inner wall of the housing. A rotating tube is rotatably connected to the inner wall of the fixed bracket. An installation box is connected through the bottom of the rotating tube.

[0009] Preferably, the collection assembly further includes a bevel gear II fixedly connected to the top of the rotating pipe. Four fan blades are fixedly connected to the side wall of the installation box. An inclined plate is fixedly connected to the inner wall of the discharge pipe. A cleaning assembly is fixedly connected to the inner wall of the installation box. Taking advantage of the feature that the bottom of the gypsum board is cut by the above saw blade, a cutting mechanism and a collection assembly are provided inside the device. When the gear I rotates, the gear I drives the bevel gear II to rotate through the gear II and the bevel gear I. The bevel gear II drives the installation box and the fan blades at the bottom through the rotating pipe, 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 housing through the discharge pipe along the inner wall of the inclined plate.

[0010] Preferably, the cleaning assembly includes a counterweight slidably connected to the side wall of the fan blade. A hydraulic telescopic rod is fixedly connected to the side wall of the counterweight. An L-shaped pipe is connected through the inner wall of the installation box. The end of the hydraulic telescopic rod away from the counterweight is connected through the side wall of the L-shaped pipe. Since the gypsum board is driven by the conveyor belt and entirely covers the top of the cutting mechanism, at this time, restricted by the dust baffle, the bottom of the gypsum board, and the partition box, the fine particles generated by cutting will be difficult to disperse around. And at this time, the installation box and the fan blades at the bottom generate a downward air flow, which will force 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 the saw blade cutting is collected, reducing the amount of dust flowing outwards.

[0011] Preferably, the cleaning assembly further includes a piston block slidably connected to the inner wall of the L-shaped pipe. 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. 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 bevel gear II. Taking advantage of the feature that the installation box drives the fan blade to rotate to generate centrifugal force, a cleaning assembly is provided inside the device. As the rotation speed of the installation box continuously increases, the centrifugal force received by 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, it will scrape and clean the outer wall of the fan blade. When the counterweight moves outward, the counterweight drives the hydraulic telescopic rod to extend outward synchronously, causing the liquid inside the L-shaped pipe to enter the hydraulic telescopic rod, forcing the piston block to drive the linkage rod to slide downward along the inner wall of the L-shaped pipe. When the linkage rod drives the ring to move downward, it forces the spring to deform and accumulate mechanical power. After the device completes cutting, the motor stops running, and the spring will release the mechanical power, driving the piston block to reset through the linkage rod. The piston block drives the counterweight to reset along the inner wall of the fan blade. After the device stops running, the counterweight will clean the outer wall of the fan blade again. Through the application of the above components, it effectively avoids dust particles from adhering to the outer wall of the fan blade, affecting the efficiency of the fan blade driving air flow.

[0012] Preferably, the outer wall of the bevel gear II is meshed and connected with the outer wall of the bevel gear I, the outer wall of the gear II is meshed and connected with the outer wall of the gear I, the outer wall of the gear I is meshed and connected with the inner wall of the tooth marks, one end of the transmission belt away from the rotating column is rotationally connected with the outer wall of the driving rod, and the outer wall of the inclined panel is slidably connected with the inner wall of the transmission belt. By using the characteristic that the above-mentioned multiple counterweights drive the piston block to slide up and down along the inner wall of the L-shaped pipe, a ring is arranged inside the device. If a relatively large particle of gypsum board adheres to the outer wall of one of the fan blades, the corresponding counterweight will be difficult to move horizontally outwards. When the blocked counterweight is difficult to move outwards, the corresponding piston block will also stop moving along the inner wall of the L-shaped pipe. The blocked piston block will restrict the further downward movement of the linkage rod, and the blocked linkage rod will force the ring to stop operating. The stopped ring will restrict the operation of the remaining counterweights. Through the application of the above components, it is ensured that the horizontal movement speed and length of the counterweights on the outer wall of the corresponding fan blades are equal, avoiding the unequal positions of the counterweights and causing the rotation center of gravity of the fan blade to shift, which affects the exhaust effect of the fan blade.

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

[0014] S1: Place the board;

[0015] S2: Turn on the power supply;

[0016] S3: Start cutting.

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

[0018] (1) By utilizing the characteristics that the gypsum board is hard and brittle, an extrusion mechanism and a cutting mechanism are arranged inside the device. Before use, the gypsum board is placed on the top of the transmission belt, and then the power supply of the motor is turned on. At this time, the motor forces the transmission belt to slide along the outer wall of the inclined panel through the driving rod. During the operation of the transmission belt, the transmission belt drives the gypsum board to contact the outer wall of the saw blade. When the driving rod rotates, the driving rod drives the rotating column to rotate in the same direction through the transmission belt, and the rotating column drives the rotating rod and the saw blade to rotate in the reverse direction through the gear I and the tooth marks. At this time, the saw blade will cut the bottom of the gypsum, making a cutting line appear at the bottom of the gypsum. As the transmission belt continues to move, affected by the inward inclination of the two inclined panels, when the gypsum board moves with the transmission belt, the bottom of the gypsum board will gradually become hollow, and after the top of the gypsum contacts the outer wall of the roller, affected by the downward inclination of the fixed rod, the roller will apply a pressure to the top of the gypsum board, forcing the gypsum board to fold downwards with the cutting line at the bottom as the center line, presenting a state as shown in Figure 6 G in the figure. The transmission belt drives the broken gypsum board to continue to move, and the cutting knife will cut the crack of the gypsum board to remove the paper material on the outer wall of the gypsum board. Through the application of the above components, the cutting area is reduced, and finally the gypsum board is broken by applying pressure, greatly reducing the total amount of dust generated during gypsum cutting.

[0019] (2) By taking advantage of the characteristics that the above-mentioned saw blade cuts the bottom of the gypsum board, a cutting mechanism and a collection component are arranged inside the equipment. When the first gear rotates, the first gear drives the second bevel gear to rotate through the second gear and the first bevel gear, and the second bevel gear drives the installation box and the fan blade at the bottom to rotate through the rotating pipe, so that the fan blade generates a downward suction force. During this process, most of the gypsum powder generated by the saw blade cutting will enter the bottom of the housing along the inner wall of the inclined plate through the discharge pipe. In addition, since the gypsum board is driven by the conveyor belt and covers the top of the cutting mechanism as a whole, at this time, restricted by the dust baffle, the bottom of the gypsum board and the partition box, the fine particles generated by cutting will be difficult to disperse around. And at this time, the installation box and the fan blade at the bottom generate a downward air flow, which will force most of the dust to flow out downward through the discharge pipe and various gaps. Through the application of the above components, most of the dust generated during the saw blade cutting is collected, and the amount of dust flowing outwards is reduced.

[0020] (3) By taking advantage of the characteristics that the above-mentioned installation box drives the fan blade to rotate to generate centrifugal force, a cleaning component is arranged inside the equipment. As the rotation speed of the installation box continues to increase, the centrifugal force received by the counterweight also increases synchronously. During this process, the counterweight will move outwards 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 outwards, the counterweight drives the hydraulic telescopic rod to extend outwards synchronously, so that the liquid inside the L-shaped pipe enters the hydraulic telescopic rod, forcing the piston block to drive the linkage rod to slide down along the inner wall of the L-shaped pipe. When the linkage rod drives the ring to move down, the spring will be deformed and mechanical power will be stored. After the equipment finishes cutting, the motor stops running, and the spring will release the mechanical power, driving the piston block to reset through the linkage rod. 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, it effectively avoids dust particles adhering to the outer wall of the fan blade and affecting the efficiency of the fan blade driving air flow.

[0021] (4) By taking advantage of the characteristics that the above-mentioned multiple counterweights drive the piston block to slide up and down along the inner wall of the L-shaped pipe, a ring is arranged inside the equipment. If a relatively large particle of gypsum board adheres to the outer wall of one of the fan blades, the corresponding counterweight will be difficult to move outwards horizontally. When the blocked counterweight is difficult to move outwards, the corresponding piston block also stops moving along the inner wall of the L-shaped pipe. The blocked piston block will limit the linkage rod from continuing to move downwards, and the blocked linkage rod will force the ring to stop running. The stopped ring will limit the operation of the other counterweights. Through the application of the above components, it ensures that the horizontal movement speed and length of the counterweights on the outer wall of the corresponding fan blades are equal, avoiding the rotation center of the fan blade from shifting due to unequal positions of the counterweights and affecting the exhaust effect of the fan blade.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope 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 a driving rod 12. A transmission belt 13 is rotatably connected to the outer walls of the two driving rods 12;

[0038] An extrusion mechanism 2, the extrusion mechanism 2 includes a support frame 21 fixedly connected to the top of the chassis 1. One end of the support frame 21 away from the chassis 1 is fixedly connected to an inclined panel 22. A fixed rod 23 is fixedly connected to the top of the chassis 1. A plurality of rollers 25 are rotatably connected to the bottom of the fixed rod 23. A cutting knife 24 is fixedly connected to the side wall of the fixed rod 23;

[0039] Cutting mechanism 3, the cutting mechanism 3 includes a housing 31 fixedly connected to the top of the chassis 1. An isolation box 32 is fixedly connected to the inner wall of the housing 31. A discharge pipe 39 is connected through the inner wall of the isolation box 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 first 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 provided 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 collection assembly 4 is fixedly connected to the inner wall of the housing 31. Utilizing the characteristics that the gypsum board is hard and brittle, an extrusion mechanism 2 and a cutting mechanism 3 are provided inside the device. Before use, the gypsum board is placed on the top of the conveyor belt 13. Subsequently, 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 driving rod 12. During the operation of the conveyor belt 13, the conveyor belt 13 drives the gypsum board to contact the outer wall of the saw blade 38. When the driving rod 12 rotates, the driving rod 12 drives the rotating column 33 to rotate in the same direction through the transmission belt 34. And the rotating column 33 drives the rotating rod 36 and the saw blade 38 to rotate in the reverse direction through the first gear 35 and the tooth marks 37. And at this time, the saw blade 38 will cut the bottom of the gypsum, making a cutting line appear at the bottom of the gypsum. As the conveyor belt 13 continues to move, affected by the inward inclination of the two inclined panels 22, when the gypsum board moves with the conveyor belt 13, the bottom of the gypsum board will gradually present a hollow state. And after the top of the gypsum contacts the outer wall of the roller 25, the roller 25 will apply a pressure to the top of the gypsum board under the influence of the downward inclination of the fixed rod 23, forcing the gypsum board to fold downward with the cutting line at the bottom as the center line, presenting a state as shown in Figure 6 in G. The conveyor belt 13 drives the broken gypsum board to continue to move, and the cutting knife 24 will cut the crack of the gypsum board to remove the paper material on the outer wall of the gypsum board. Through the application of the above components, the cutting area is reduced, and finally the gypsum board is broken by applying pressure, greatly reducing the total amount of dust generated during gypsum cutting.

[0040] Embodiment 2, please refer to Figure 7 - Figure 11 In this invention, a gypsum board cutting device, on the basis of Embodiment 1, the collection assembly 4 further includes a dust baffle 41 fixedly connected to the inner wall of the housing 31. A second gear 42 is rotatably connected to the inner wall of the housing 31. A first bevel gear 43 is fixedly connected to the side wall of the second gear 42.

[0041] The collection assembly 4 further includes a fixed bracket 44 fixedly connected to the inner wall of the housing 31. A rotating tube 45 is rotatably connected to the inner wall of the fixed bracket 44. The bottom of the rotating tube 45 is connected through an installation box 47.

[0042] The collecting component 4 further includes a bevel gear II 46 fixedly connected to the top of the rotating pipe 45. Four fan blades 48 are fixedly connected to the side wall of the mounting box 47. An inclined plate 49 is fixedly connected to the inner wall of the discharge pipe 39. A cleaning component 5 is fixedly connected to the inner wall of the mounting box 47. Taking advantage of the feature that the bottom of the gypsum board is cut by the saw blade 38, a cutting mechanism 3 and a collecting component 4 are arranged inside the device. When the gear I 35 rotates, the gear I 35 drives the bevel gear II 46 to rotate through the gear II 42 and the bevel gear I 43. The bevel gear II 46 drives the mounting box 47 and the fan blades 48 at the bottom through the rotating pipe 45 to rotate, causing the fan blades 48 to generate a downward suction force. During this process, most of the gypsum powder generated by the cutting of the saw blade 38 will enter the bottom of the housing 31 along the inner wall of the inclined plate 49 through the discharge pipe 39.

[0043] The cleaning component 5 includes a counterweight block 51 slidably connected to the side wall of the fan blade 48. A hydraulic telescopic rod 52 is fixedly connected to the side wall of the counterweight block 51. An L-shaped pipe 53 is connected through the inner wall of the mounting box 47. One end of the hydraulic telescopic rod 52 away from the counterweight block 51 is connected through the side wall of the L-shaped pipe 53. Since the gypsum board is driven by the conveyor belt 13 and entirely covers the top of the cutting mechanism 3, at this time, restricted by the dust baffle 41, the bottom of the gypsum board, and the partition box 32, the fine particles generated by cutting will be difficult to disperse around. And at this time, the downward air flow generated by the mounting box 47 and the fan blades 48 at the bottom 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 during the cutting of the saw blade 38 is collected, reducing the amount of dust flowing outwards.

[0044] The cleaning component 5 further includes a piston block 54 slidably connected to the inner wall of the L-shaped pipe 53. A linkage rod 55 is fixedly connected to the top of the piston block 54. A circular ring 56 is fixedly connected to the top of the linkage rod 55. A spring 57 is fixedly connected to the top of the circular ring 56. One end of the spring 57 away from the circular ring 56 is fixedly connected to the inner wall of the bevel gear II 46. By using the characteristic that the above-mentioned installation box 47 drives the fan blade 48 to rotate to generate centrifugal force, a cleaning component 5 is arranged inside the device. As the rotation speed of the installation box 47 continuously increases, the centrifugal force received by the counterweight block 51 also synchronously increases. During this process, the counterweight block 51 will move outward along the outer wall of the fan blade 48. During the displacement of the counterweight block 51, the outer wall of the fan blade 48 will be scraped and cleaned. When the counterweight block 51 moves outward, the counterweight block 51 drives the hydraulic telescopic rod 52 to extend outward synchronously, so that the liquid inside the L-shaped pipe 53 enters the hydraulic telescopic rod 52, forcing the piston block 54 to drive the linkage rod 55 to slide downward along the inner wall of the L-shaped pipe 53. When the linkage rod 55 drives the circular ring 56 to move downward, the spring 57 is forced to deform and accumulate mechanical power. After the device completes cutting, the motor 11 stops running, and the spring 57 will release the mechanical power, driving 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 device stops running, the counterweight block 51 will clean the outer wall of the fan blade 48 again. Through the application of the above components, it effectively avoids dust particles from adhering to the outer wall of the fan blade 48 and affecting the efficiency of the fan blade 48 to drive air flow.

[0045] The outer wall of the bevel gear II 46 is meshed and connected with the outer wall of the bevel gear I 43. The outer wall of the gear II 42 is meshed and connected with the outer wall of the gear I 35. The outer wall of the gear I 35 is meshed and connected with the inner wall of the tooth mark 37. One end of the transmission belt 34 away from the rotating column 33 is rotatably connected to the outer wall of the driving rod 12. The outer wall of the inclined panel 22 is slidably connected to the inner wall of the transmission belt 13. By using the characteristic that the above-mentioned multiple counterweight blocks 51 drive the piston block 54 to slide up and down along the inner wall of the L-shaped pipe 53, a circular ring 56 is arranged inside the device. If a relatively large particle of gypsum board adheres to the outer wall of one of the fan blades 48, the corresponding counterweight block 51 will be difficult to move outward horizontally. When the blocked counterweight block 51 is difficult to move outward, the corresponding piston block 54 also stops moving on the inner wall of the L-shaped pipe 53. The blocked piston block 54 will limit the linkage rod 55 from continuing to move downward, and the blocked linkage rod 55 will force the circular ring 56 to stop running. The stopped circular ring 56 will limit the operation of the remaining counterweight blocks 51. Through the application of the above components, it ensures that the horizontal movement speed and length of the counterweight block 51 on the outer wall of the corresponding fan blade 48 are equal, avoiding the rotation center of the fan blade 48 from shifting due to unequal positions of the counterweight blocks 51 and affecting the exhaust effect of the fan blade 48.

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

[0047] S1: Place the board;

[0048] S2: Turn on the power supply;

[0049] S3: Start cutting.

[0050] A specific application of this embodiment is as follows: Before use, place the gypsum board on the top of the conveyor belt 13, and then turn on the power supply of the motor 11. At this time, the motor 11 forces the conveyor belt 13 to slide along the outer wall of the inclined panel 22 through the driving rod 12. During the operation of the conveyor belt 13, the conveyor belt 13 drives the gypsum board to contact the outer wall of the saw blade 38. When the driving rod 12 rotates, the driving rod 12 drives the rotating column 33 to rotate in the same direction through the transmission belt 34, and the rotating column 33 drives the rotating rod 36 and the saw blade 38 to rotate in the reverse direction through the first gear 35 and the tooth marks 37. At this time, the saw blade 38 will cut the bottom of the gypsum, creating a cutting line at the bottom of the gypsum. As the conveyor belt 13 continues to move, affected by the inward inclination of the two inclined panels 22, when the gypsum board moves with the conveyor belt 13, the bottom of the gypsum board will gradually become hollow, and after the top of the gypsum contacts the outer wall of the roller 25, the roller 25 will apply a pressure to the top of the gypsum board under the influence of the downward inclination of the fixed rod 23, forcing the gypsum board to fold downward with the cutting line at the bottom as the center line, presenting the state as shown in Figure 6 state G in the figure. The conveyor belt 13 drives the broken gypsum board to continue moving, and the cutting knife 24 will cut the crack of the gypsum board to remove the paper material on the outer wall of the gypsum board. Through the application of the above components, the cutting area is reduced, and finally the gypsum board is broken by applying pressure, greatly reducing the total amount of dust generated during gypsum cutting.

[0051] Utilizing the feature of the saw blade 38 cutting the bottom of the gypsum board, a cutting mechanism 3 and a collection component 4 are provided inside the device. When the first gear 35 rotates, the first gear 35 drives the second gear 42 and the first bevel gear 43 to drive the second bevel gear 46 to rotate. The second bevel gear 46 drives the installation box 47 and the fan blade 48 at the bottom through the rotating tube 45 to rotate, causing the fan blade 48 to generate a downward suction force. During this process, most of the gypsum powder generated by the cutting of the saw blade 38 will enter the bottom of the housing 31 along the inner wall of the inclined plate 49 through the discharge pipe 39; in addition, since the gypsum board is driven by the conveyor belt 13 and completely covers the top of the cutting mechanism 3, restricted by the dust-proof plate 41, the bottom of the gypsum board, and the partition box 32, the fine particles generated by cutting are difficult to disperse in all directions. At this time, the installation box 47 and the fan blade 48 at the bottom generate a downward air flow, forcing 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 during the cutting of the saw blade 38 is collected, reducing the amount of dust flowing outwards.

[0052] Taking advantage of the characteristic that the above-mentioned installation box 47 drives the fan blade 48 to rotate to generate centrifugal force, a cleaning component 5 is arranged inside the device. As the rotation speed of the installation box 47 continuously increases, the centrifugal force received by the counterweight block 51 also synchronously increases. During this process, the counterweight block 51 will move outward along the outer wall of the fan blade 48. During the displacement of the counterweight block 51, it will scrape and clean the outer wall of the fan blade 48. When the counterweight block 51 moves outward, the counterweight block 51 drives the hydraulic telescopic rod 52 to extend outward synchronously, causing the liquid inside the L-shaped pipe 53 to enter the inside of the hydraulic telescopic rod 52, forcing the piston block 54 to drive the linkage rod 55 to slide downward along the inner wall of the L-shaped pipe 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 device completes cutting, the motor 11 stops running, and the spring 57 will release the mechanical power, driving 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 device stops running, the counterweight block 51 will clean the outer wall of the fan blade 48 again. Through the application of the above components, it effectively avoids dust particles from adhering to the outer wall of the fan blade 48 and affecting the efficiency of the fan blade 48 in driving air flow.

[0053] Taking advantage of the characteristic that the above-mentioned multiple counterweight blocks 51 drive the piston block 54 to slide up and down along the inner wall of the L-shaped pipe 53, a ring 56 is arranged inside the device. If a relatively large particle of gypsum board adheres to the outer wall of one of the fan blades 48, the corresponding counterweight block 51 will be difficult to move horizontally outward. When the blocked counterweight block 51 is difficult to move outward, the corresponding piston block 54 also stops moving along the inner wall of the L-shaped pipe 53. The blocked piston block 54 will limit the linkage rod 55 from continuing to move downward, and the blocked linkage rod 55 will force the ring 56 to stop running. The stopped ring 56 will limit the operation of the remaining counterweight blocks 51. Through the application of the above components, it ensures that the horizontal movement speed and length of the counterweight block 51 on the outer wall of the corresponding fan blade 48 are equal, avoiding the rotation center of the fan blade 48 from shifting due to unequal positions of the counterweight blocks 51 and affecting the exhaust effect of the fan blade 48.
