Description

Technical Field

[0001] This utility model relates to the field of gypsum board production technology, and in particular to a dustproof cutting device for gypsum board production. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, and easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties, making it one of the new lightweight building materials currently under development. During production, gypsum board is cut to the corresponding specifications using a cutting device according to customer requirements.

[0003] A fan is installed near the cutting device. When the blade generates heat while cutting the plasterboard, the fan runs and blows cool air toward the blade. The airflow carries away the heat, thus cooling the board. A graduated scale is set on the workbench of the cutting device. The operator can visually observe and manually adjust the position of the plasterboard to align the cutting line with the scale, thereby ensuring consistent cutting length. A heavy weight is placed on top of the plasterboard to stabilize it. The shape and size of the weight can be selected according to the size of the plasterboard, and it is generally a rectangular or square metal block.

[0004] Air cooling has relatively low efficiency, and for blades that rotate at high speeds and cut for extended periods, it may not be able to reduce the blade temperature in a timely and effective manner. Moreover, the air blown out by the fan may blow plaster dust generated during cutting everywhere, affecting the working environment and the health of operators. It relies on the operator's experience and attention, and is prone to human error. Furthermore, frequent manual adjustment of the plasterboard position is tedious and inefficient in large-scale production. The pressure block is not precise enough, and due to its own weight or vibration during the cutting process, it leaves indentations on the surface of the plasterboard, affecting the appearance quality of the plasterboard. The pressure block cannot cover and fix the plasterboard well, resulting in a lot of wasted time and effort in the fixing process, reducing production efficiency. To address the above problems, a dustproof cutting device for plasterboard production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof cutting device for gypsum board production, which solves the problems of low efficiency of air cooling, inability to cool the blade in time, need for manual adjustment of the gypsum board position, limited accuracy of fixing the gypsum board, poor adaptability and easy damage to the gypsum board in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof gypsum board production cutting device, comprising a workbench, a gas storage tank fixedly connected to the top center of the workbench, an air pump fixedly connected to the bottom inner wall of the gas storage tank, a hose fixedly connected to the bottom of the air pump, the outer wall of the hose penetrating and fixedly connected to the top center of the workbench, a valve penetrating and fixedly connected to the middle of the outer wall of the hose, a vortex chamber penetrating and fixedly connected to the bottom of the hose, a separation orifice plate fixedly connected to the rear end of the inner wall of the vortex chamber, a cold end pipe fixedly connected to the inner wall of the separation orifice plate, a hot end pipe fixedly connected to the front end of the vortex chamber, a hot end control valve fixedly connected to the front end of the hot end pipe, an adjustment component for adjusting the size of the gypsum board provided on the top side of the workbench, and a fixing component for fixing the gypsum board provided on the bottom side of the workbench.

[0007] By adopting the above technical solution, the valve is opened and the air pump sends the compressed air from the gas storage tank into the vortex chamber through the hose. After the air forms a vortex in the chamber, it is divided into two parts, light and heavy, due to centrifugal force. After energy separation, the hot gas is discharged from the hot end pipe and the cold gas is blown from the cold end pipe toward the cutting blade, which quickly cools the cutting blade.

A cylinder is fixedly connected to the bottom of the fixing frame, and the output end of the cylinder is fixedly connected to the bottom of one of the sliding blocks.

[0009] By adopting the above technical solution, the cylinder is opened, and its output end causes the sliding block to move, which in turn moves the fixed plate and the first pull rod.

[0010] As a further description of the above technical solution: a fixed plate is fixedly connected to the top of the sliding block, the bottom outer wall of the fixed plate is slidably connected to both ends of the worktable, a uniformly distributed spring is fixedly connected to both ends of the fixed plate, a fixed block is fixedly connected to one end of the spring, and a roller is rotatably connected to the inner wall of the fixed block.

[0011] By adopting the above technical solution, the gypsum board is fixed by squeezing the rollers, which in turn drive the fixing block to squeeze the spring, effectively buffering the impact force and preventing damage to the gypsum board.

[0012] As a further description of the above technical solution: the adjustment component includes a rack, the outer wall of the rack is slidably connected to the middle of the top side of the worktable, a movable plate is fixedly connected to the top of the rack, and pointers are fixedly connected to the top of both ends of the movable plate.

[0013] By adopting the above technical solution, the rack moves, driving the moving plate to move, and the moving plate drives the pointer to move.

The top of the worm wheel is meshed with the bottom of the rack, and the bottom of the worm wheel is meshed with the top of the worm. A scale is fixedly connected to the top of both ends of one side of the workbench.

[0015] By adopting the above technical solution, the second motor is started, and its output end drives the worm to rotate, thereby causing the worm wheel to rotate, which in turn drives the rack to move, and the pointer moves to point to the scale.

[0016] As a further description of the above technical solution: a push rod motor is fixedly connected to the middle of the front end of the worktable, and a moving frame is fixedly connected to the output end of the push rod motor. The inner wall of the moving frame is slidably connected to the middle of the top of the worktable, and one side of the front end of the moving frame is fixedly connected to one side of the vortex chamber.

[0017] By adopting the above technical solution, the push rod motor is started, and its output end drives the moving frame to move. The moving frame can drive the vortex chamber to move, thereby cooling the blade.

[0018] As a further description of the above technical solution: a vacuum suction hose is fixedly connected to one side of the rear end of the mobile frame. The outer wall of the vacuum suction hose penetrates and is fixedly connected to the top rear end of the workbench. A vacuum suction hood is fixedly connected to the bottom of the vacuum suction hose. A collection box is penetrated and fixedly connected to the bottom of the vacuum suction hose. A fan is fixedly connected to the front end of the collection box. A filter screen is fixedly connected to the inner wall of the front end of the collection box.

[0019] By adopting the above technical solution, the fan is turned on, and the suction force it generates draws the dust produced by cutting plaster from the dust hood through the dust suction hose into the collection box. The filter screen inside the box can prevent impurities from damaging the fan.

[0020] As a further description of the above technical solution: a first motor is fixedly connected to the bottom of the movable frame, and a cutting blade is fixedly connected to the output end of the first motor.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0035] Combination Figure 1 and Figure 5This utility model discloses a dustproof gypsum board production cutting device, including a workbench 1. The workbench 1 provides a flat working surface for the gypsum board cutting operation. A fixing component for fixing the gypsum board is provided on one side of the bottom of the workbench 1. During the cutting process, the gypsum board will be subjected to the cutting force of the cutting blade 16. If it is not fixed, the gypsum board will move, resulting in problems such as inaccurate cutting dimensions and uneven cutting surfaces. The fixing component can keep the gypsum board stable during cutting, ensuring that the cutting operation can be carried out according to the predetermined requirements. A push rod motor 11 is fixedly connected to the middle of the front end of the workbench 1. A moving frame 12 is fixedly connected to the output end of the push rod motor 11. When the push rod motor 11 is started, its output end can drive the moving frame 12 to move. The inner wall of the moving frame 12 is slidably connected to the middle of the top of the workbench 1. One side of the front end of the moving frame 12 is fixedly connected to one side of the vortex chamber 17. The rear end of the moving frame 12 is... A vacuum hose 10 is fixedly connected to the side. The outer wall of the vacuum hose 10 passes through and is fixedly connected to the top rear end of the workbench 1. A vacuum hood 14 is fixedly connected to the bottom of the vacuum hose 10. A collection box 5 is fixedly connected to the bottom of the vacuum hose 10. A fan 4 is fixedly connected to the front end of the collection box 5. A filter screen 36 is fixedly connected to the inner wall of the front end of the collection box 5. When the fan 4 is turned on, it generates suction, which sucks in the dust generated when cutting plaster first through the vacuum hood 14, then through the vacuum hose 10, and finally into the collection box 5. The filter screen 36 in the collection box 5 can effectively block impurities and prevent the fan 4 from being damaged by impurities. A first motor 15 is fixedly connected to the bottom of the moving frame 12. A cutting blade 16 is fixedly connected to the output end of the first motor 15. The cutting blade 16 is a component that directly cuts the plasterboard. When the first motor 15 is turned on, its output end drives the cutting blade 16 to rotate and cut the plasterboard.

[0036] Combination Figures 1-3 and Figure 6A gas storage tank 9 is fixedly connected to the top center of the workbench 1. An air pump 37 is fixedly connected to the bottom inner wall of the gas storage tank 9. A hose 22 is fixedly connected to the bottom of the air pump 37, and the outer wall of the hose 22 penetrates and is fixedly connected to the top center of the workbench 1. A valve 18 is fixedly connected to the middle of the outer wall of the hose 22. A vortex chamber 17 is fixedly connected to the bottom of the hose 22. A separation orifice plate 20 is fixedly connected to the rear end of the inner wall of the vortex chamber 17. A cold end pipe 21 is fixedly connected to the inner wall of the separation orifice plate 20. A hot end pipe 23 is fixedly connected to the front end of the vortex chamber 17. A hot-end control valve 24 is fixedly connected to the end. After opening the valve 18, the air pump 37 sends compressed air from the gas storage tank 9 into the vortex chamber 17 through the hose 22. In the vortex chamber 17, the compressed air forms a high-speed vortex. Due to centrifugal force, the gas is divided into light and heavy parts. Energy separation occurs through molecular friction and collision. The hot gas is discharged from the hot-end pipe 23, and the cold gas is blown towards the cutting blade 16 from the cold-end pipe 21. The separation plate 20 promotes energy separation, effectively and quickly reducing the temperature of the cutting blade 16, reducing wear and thermal deformation caused by high temperature, ensuring the straightness and sharpness of the cutting edge, and making the cut edge of the gypsum board smoother. The sliding mechanism improves the pass rate and can accurately provide cooling based on the blade temperature, stabilizing the temperature. An adjustment assembly for adjusting the gypsum board size is installed on the top side of the workbench 1. The adjustment assembly includes a rack 28, whose outer wall is slidably connected to the middle of the top side of the workbench 1. A movable plate 8 is fixedly connected to the top of the rack 28, and pointers 7 are fixedly connected to the top of both ends of the movable plate 8. A second motor 25 is fixedly connected to one side of the inner wall of the workbench 1, and a worm gear 27 is fixedly connected to the output end of the second motor 25. A worm wheel 26 is rotatably connected to the other side of the inner wall of the workbench 1, and the top of the worm wheel 26 is connected to the rack. The bottom of the worm gear 28 is engaged with the bottom of the worm wheel 26, which is engaged with the top of the worm 27. A scale 6 is fixedly connected to the top of both ends of one side of the worktable 1. When the second motor 25 is turned on, its output drives the worm 27 to rotate. The rotation of the worm 27 causes the worm wheel 26 to rotate accordingly, which in turn drives the rack 28 to move. During the movement of the rack 28, the moving plate 8 moves synchronously. The pointer 7 on the moving plate 8 points to the scale 6, achieving precise adjustment of the length of the cut gypsum board, ensuring a fixed cutting position, uniform gypsum board dimensions, and reducing the defect rate caused by size issues. Operation is simple, requiring no complex training, and personnel can quickly adjust the cutting position according to production needs, effectively improving work efficiency and ensuring smooth production.

[0037] Combination Figure 1 and Figure 4The fixing assembly includes a fixing frame 3, which provides stable support for the fixing assembly. The top of the fixing frame 3 is fixedly connected to the bottom of one side of the worktable 1. A rotating shaft 29 is rotatably connected to the middle of the top of the fixing frame 3. A rotating plate 33 is fixedly connected to the outer wall of the rotating shaft 29. Fixing shafts 30 are fixedly connected to both sides of the rotating plate 33. A first pull rod 31 is rotatably connected to the outer wall of the left fixing shaft 30, and a second pull rod 38 is rotatably connected to the outer wall of the right fixing shaft 30. Sliding blocks 32 are rotatably connected to the bottom of the rear end of the first pull rod 31 and the bottom of the front end of the second pull rod 38. A cylinder 34 is fixedly connected to the bottom of the fixing frame 3. The output end of the cylinder 34 is fixedly connected to the bottom of one of the sliding blocks 32. A fixing plate 2 is fixedly connected to the top of the sliding block 32. The bottom outer wall of the fixing plate 2 is slidably connected to both ends of the worktable 1. When the cylinder 34 is opened, the output end of the cylinder 34 drives... One of the sliding blocks 32 begins to move. During the movement of the sliding block 32, it drives the fixed plate 2 and the first pull rod 31 connected to it to move together. The movement of the first pull rod 31 causes the rotating plate 33 to rotate, and the rotation of the rotating plate 33 drives the second pull rod 38 to move. Finally, the second pull rod 38 drives the other fixed plate 2 to move, thereby firmly fixing the gypsum board in the middle position, preventing the gypsum board from shifting during the cutting process, ensuring cutting accuracy, and adapting to gypsum boards of different sizes. Both ends of the fixed plate 2 are fixedly connected with evenly distributed springs 35. One end of the spring 35 is fixedly connected to a fixed block 19. The inner wall of the fixed block 19 is rotatably connected to a roller 13. The gypsum board applies force to the roller 13, and the roller 13 squeezes the fixed block 19, causing the spring 35 to be compressed. This effectively prevents the gypsum board from being damaged by hard impact, eliminates the possibility of cracks at the edges of the gypsum board, and ensures the integrity of the gypsum board.

[0038] Working principle: Plasterboard is placed on workbench 1, cylinder 34 is opened, and the output end of cylinder 34 drives one of the sliding blocks 32 to move. When sliding block 32 moves, it drives fixed plate 2 and first pull rod 31 to move. When first pull rod 31 moves, it drives rotating plate 33 to rotate. Rotating plate 33 drives second pull rod 38 to move. The movement of second pull rod 38, in turn, drives another fixed plate 2 to move. This can tightly fix the plasterboard in the middle, preventing displacement of the plasterboard during cutting and ensuring cutting accuracy. It can adapt to plasterboard of different sizes because no matter the width of the plasterboard, it can be firmly fixed by adjusting the distance between the fixed plates 2. When the plasterboard is fixed, the plasterboard squeezes roller 13, which in turn squeezes spring 3. 5. To prevent damage to gypsum board from hard impacts and to prevent edge breakage, vibration of the gypsum board is greatly reduced during cutting, keeping cutting errors within a very small range, improving product quality, reducing additional wear on the cutting device caused by gypsum board shaking during cutting, and making the force on each component of the cutting device more even, thereby extending the service life of key equipment such as cutting blades and motors. This not only saves equipment maintenance time and improves production efficiency, but also reduces the cost of frequent component replacements. It also prevents gypsum board from accidentally slipping during cutting, ensuring the personal safety of operators. The second motor 25 is activated, and its output drives the worm gear 27 to rotate. The rotation of the worm gear 27 drives the worm wheel 26 to rotate. The rotation of wheel 26 drives the rack 28 to move, which in turn moves the moving plate 8. The pointer 7 on the moving plate 8 points to the scale 6, thus precisely adjusting the length of the cut gypsum board. This ensures that the cutting dimensions of each gypsum board are consistent, meeting strict product standards. It guarantees that each cutting action is performed in the same position, resulting in highly consistent length, width, and other dimensions of the cut gypsum boards. This reduces product quality issues caused by dimensional differences. Operators do not require complex training and can quickly adjust the cutting position according to production requirements, improving work efficiency. Operators can quickly find the corresponding cutting dimensions on the scale 6 according to product order requirements and quickly adjust the position of the moving plate 8, reducing delays caused by equipment adjustments. This reduces production downtime, improves overall production efficiency, maintains stable cutting quality and speed, and allows for continuous and efficient operation, thereby increasing output per unit time. All cut gypsum boards are of consistent size, effectively avoiding defects caused by inaccurate cutting dimensions and improving product qualification rate. The push rod motor 11 is activated, and its output drives the moving frame 12. The first motor 15 is activated, and its output drives the cutting blade 16 to rotate, cutting the gypsum board. During cutting, valve 18 is opened, and the air pump 37 delivers compressed air from the gas storage tank 9 to the hose 22, which then enters the vortex chamber 17. The compressed air enters the vortex chamber 17, forming a high-speed rotating vortex. Due to centrifugal force...The gas is divided into two parts: heavier gas molecules are pushed to the outside of the vortex chamber 17, while lighter gas molecules gather towards the center. Due to friction and collision, energy separation occurs, causing high-temperature gas to exit through the hot-end pipe 23 and low-temperature gas to exit through the cold-end pipe 21. This low-temperature gas is then blown towards the cutting blade 16. The separation plate 20 promotes energy separation, rapidly reducing the temperature of the cutting blade 16 and maintaining its operating temperature within a low and stable range. This significantly reduces blade wear caused by high temperatures, effectively preventing thermal deformation of the blade and ensuring the straightness and sharpness of the cutting edge. This results in a smoother, more even cut edge on the gypsum board, reducing post-cutting stress. The continuous processing step improves the product qualification rate, stabilizes the blade temperature, and avoids excessive heat impact on the gypsum board, thus significantly reducing edge chipping during gypsum board cutting. This improves the product's appearance quality and dimensional accuracy. It can precisely provide the required cooling capacity according to the actual temperature requirements of the blade, achieving accurate blade cooling, which helps maintain the stability of the cutting process and reduces vibration and impact caused by blade thermal deformation or uneven wear. When the fan 4 is turned on, it generates suction, drawing dust generated from cutting the gypsum board into the suction hose 10 through the dust hood 14, and then into the collection box 5 through the suction hose 10. The filter screen 36 prevents impurities from damaging the fan 4.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
