Description

Technical Field

[0001] This invention relates to the field of imitation stone brick cutting devices, specifically a dustproof device for imitation stone brick cutting based on negative pressure adsorption. Background Technology

[0002] The stone-look brick cutting device is a high-precision processing equipment specifically designed for new building materials such as stone-look ceramic tiles and quartz bricks. It primarily addresses problems associated with traditional cutting methods, such as edge chipping, excessive dust, and low efficiency. By optimizing blade materials, such as using diamond saw blades, and cooling methods, typically employing automatic water circulation cutting, this device achieves smooth, flat edges on stone-look bricks, maximizing the reproduction of the natural texture of stone. Its structure usually includes high-precision guide rails, an adjustable cutting angle worktable, and a high-power motor to accommodate bricks of varying thicknesses and sizes.

[0003] For a specific example of an existing imitation stone brick cutting device, please refer to application number CN202422655011.5, which describes a PC imitation stone brick cutting device with a quick-change blade. The device includes: a support frame; a fixed frame is fixedly connected to one side of the support frame; a housing is fixedly connected to one side of the fixed frame; a shaft is rotatably connected to the middle of the other side of the housing; a drive mechanism is provided at one end of the shaft; a fixed sleeve is fixedly connected to the other end of the shaft; a cutting blade and a first positioning disc are respectively fitted on the outer side of the fixed sleeve from the outside to the inside; and a second positioning disc is connected to the end of the fixed sleeve. By simultaneously pulling the four arc-shaped sleeves outwards and compressing the return spring, the positioning shaft is removed from the inside of the second insertion hole. This facilitates the sliding of the first positioning disc, allowing the positioning disc to be removed from the outside of the fixed sleeve. Simultaneously, the insertion rod is removed from the inside of the third insertion hole and the first insertion hole, thus facilitating the removal and replacement of the cutting blade from the outside of the fixed sleeve. The aforementioned device does not include a dustproof component. Since a large amount of dust will be generated when cutting imitation stone bricks, if the dust generated during cutting is not absorbed and treated in time, it will easily lead to pollution of the working environment and thus threaten the health of the workers. Therefore, in order to address the above problem, a dustproof device for cutting imitation stone bricks based on negative pressure adsorption is proposed. Summary of the Invention

The other end of the third fixing frame 39 is fixedly connected to the top of the filter element 29. The top of the fixing block 31 is fixedly connected to the bottom of the fixing box 41. The inside of the fixing box 41 is fixedly connected to the guide rod 42. The front and rear ends of the outer side of the guide rod 42 are also fitted with moving blocks 43, and the guide rod 42 is slidably connected to the moving blocks 43. The guide rod 42 has a round rod design. The front and rear ends of the outer side of the guide rod 42 are also fitted with third return springs 44. One end of the third return spring 44 is fixedly connected to the fixed box 41, and the other end of the third return spring 44 is fixedly connected to the moving block 43; the top end of the moving block 43 is fixedly connected to the bottom end of the first fixed seat 45, the top of the first fixed seat 45 is sleeved on the outer side of the top end of the first fixed seat 45, and the first fixed seat 45 is rotatably connected to the first rotating head 46, the top end of the first rotating head 46 is fixedly connected to the bottom end of the rotating rod 47, the top end of the rotating rod 47 is fixedly connected to the bottom end of the second rotating head 48, the second rotating head 48 is sleeved on the outer side of the bottom end of the second fixed seat 49, and the second rotating head 48 is rotatably connected to the second fixed seat 49, the top end of the second fixed seat 49 is fixedly connected to the bottom end of the top plate 50, the top end of the top plate 50 abuts against the bottom end of the second fixed platform 38, and the top plate 50 is square in design; During operation, the motor 12 below the mobile cutting table 2 is started. When the motor 12 starts, it drives the turbine 11 to rotate inside the fan body 10. The second fixing frame 23 is used to fix and support the position of the fan body 10. At the same time, when the turbine 11 rotates, it will generate suction. Through the cooperation of the first connecting pipe 13 and the dust suction head 14, the dust generated by cutting above the mobile cutting table 2 is sucked into the fan body 10. The baffle box 15 can prevent large stones from being sucked into the fan body 10 and damaging the turbine 11. Then, the fan body 10 transports the dust to the filter water tank 25 through the second connecting pipe 24. At this time, the filter water tank 25 is filled with water, so the dust directly mixes with the filter water. The water inside tank 25 undergoes a first-stage filtration process, followed by gas that is transported through the third connecting pipe 27 to the exhaust head 28 for discharge. Simultaneously, as the gas is discharged through the exhaust head 28, it undergoes a final-stage filtration by the filter element 29. The sealing ring 30 abutting against the outer side of the filter element 29 provides a seal, preventing unfiltered gas from escaping through the gap between the exhaust head 28 and the filter element 29. When replacing the filter element 29 and the wastewater inside the filtered water tank 25 after prolonged filtration, simply rotate the sealing cover 52. As the sealing cover 52 rotates, it will rotate along the outer side of the bottom end of the fourth connecting pipe 51 and move downwards until it is completely detached from the outer side of the fourth connecting pipe 51. The wastewater inside the filtered water tank 25 will then be discharged. Exhaust air is discharged outward through the fourth connecting pipe 51. Then, in the opposite direction, the sealing cap 52 is turned to seal again along the bottom end of the fourth connecting pipe 51. Then, the pressing plates 33 on both sides of the exhaust head 28 are pressed inward simultaneously. When the pressing plates 33 are pressed inward, they will simultaneously drive the pressing rod 32 to retract and move along the inside of the fixing block 31. At the same time, the second return spring 34 inside the fixing block 31 is compressed and retracts and moves synchronously. When the pressing rod 32 moves, it will simultaneously drive the positioning rod 36 to move along the first slide groove 35 and the inside of the insert box 37 until the positioning rod 36 is completely disengaged from the inside of the insert box 37. When the positioning rod 36 is disengaged from the inside of the insert box 37, the third return spring 44 inside the fixing box 41 will automatically rebound. 4. Upon rebound, the moving blocks 43 at both ends of the guide rod 42 will move simultaneously towards the center. As the moving blocks 43 move towards the center, they will cause the first fixed seat 45 and the first rotating head 46 to move synchronously. During this movement, the first rotating head 46 will rotate along the outer side of the first fixed seat 45. Simultaneously, the first rotating head 46 will cause the rotating rod 47 to rotate and move. When the rotating rod 47 rotates, it will cause the second rotating head 48 to rotate along the outer side of the second fixed seat 49, applying an upward push to the second fixed seat 49, thereby pushing the top plate 50 upward. When the top plate 50 moves upward, it simultaneously pushes the second fixed platform 38 upward. When the second fixed platform 38 moves upward...Simultaneously, the insertion box 37 will move upward along the outside of the fixing block 31, and the insertion box 37 will also move upward along the outside of the positioning block 40 until it is completely detached. Then, as the second fixing platform 38 moves upward, it simultaneously moves the third fixing bracket 39 and the filter element 29 downward. As the filter element 29 moves upward, it will move upward along the inside of the exhaust head 28 until it is completely detached, allowing for replacement. When water needs to be added, it can be injected into the filter water tank 25 through the exhaust head 28. The first fixing platform 26 provides support for the filter water tank 25. When the moving cutting table 2 moves, the fourth connecting pipe 51 will move along the inside of the third sliding groove 54, and the first connecting pipe 13 will move along the inside of the second sliding groove 53. The first fixing bracket 16 supports and fixes the vacuum head 14.

[0021] Example 2: Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown in the comparative embodiment 1, which is another implementation of the present invention, the vacuum head 14 is also fixedly connected to the left and right sides with a first fixing plate 17. The rear end of the first fixing plate 17 is fixedly connected to the front end of the fixing sleeve rod 18. The front end of the moving rod 19 is inserted inside the fixing sleeve rod 18, and the moving rod 19 is slidably connected to the fixing sleeve rod 18. The rear end of the moving rod 19 is fixedly connected to the front end of the second fixing plate 20. The side end of the second fixing plate 20 is fixedly connected to the blocking box 15. A first return spring 21 is provided inside the fixing sleeve rod 18. The front end of the first return spring 21 is fixedly connected to the front end inside the fixing sleeve rod 18, and the rear end of the first return spring 21 is fixedly connected to the front end of the moving rod 19. The moving rod 19 is a circular rod design. Limiting sliders 22 are also provided at the upper and lower ends near the front end of the outer side of the moving rod 19. The outer side of the moving rod 19 is fixedly connected to one end of the limiting slider 22, and the other end of the limiting slider 22 is inserted into the inner wall of the fixing sleeve rod 18. The limiting slider 22 is slidably connected to the fixing sleeve rod 18. During operation, when the blocking box 15 is hit by a stone, the impact energy will push the blocking box 15 to retract and move along the outside of the suction head 14. At the same time, when the blocking box 15 moves, it will drive the second fixing plate 20 and the moving rod 19 to move simultaneously. When the moving rod 19 moves, it will move along the inside of the fixing sleeve rod 18 and pressurize the first return spring 21 inside the fixing sleeve rod 18 to retract, thereby relieving the impact energy. The first fixing plate 17 is used to fix and support the position of the fixing sleeve rod 18. At the same time, when the moving rod 19 moves, it will drive the limiting slider 22 to move along the inner wall of the fixing sleeve rod 18.
