A certain amount of glass chips and dust will be generated during the scribing and cutting process of various glasses, and the requirements for dust of various glasses are inconsistent. It is necessary to ensure that the dust pollution on the glass surface is minimized during the scribing and breaking process of the glass, and the surface quality requirements of the glass are improved. Especially during the breaking process of the glass, the glass chips will splash, raise dust and fall, which will adhere to the glass surface, cause scratches on the product surface, or adhere to the glass surface at high temperature and cannot be cleaned, resulting in surface protrusions, causing unqualified appearance quality, unqualified products, affecting the output, and causing waste of resources.

[0031] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] When the above-mentioned patent is actually used, due to its open dust suction method, the dust and debris generated by the glass debris during processing have a large dispersion range, so that the generated dust cannot be comprehensively sucked in, which will cause damage to the surrounding staff. At the same time, some debris with larger mass will fall onto the workbench surface and easily cause damage during glass processing.

[0033] Therefore, the present invention provides a hot cutting dust suction device for display glass production. See Figures 1-9As shown in the figure, it includes a workbench frame 1. One side of the workbench frame 1 is fixed with a work box 2, so that a relatively enclosed space is formed during glass cutting to prevent dust from escaping. In order to facilitate the entry of glass into the work box 2, an input port 5 is provided on one side of the work box 2 close to the workbench frame 1. In order to facilitate the removal of the cut glass from one side of the work box 2, an output port 6 is provided on the other side of the work box 2. Support columns 3 are fixed at both end corners of the lower ends of the workbench frame 1 and the work box 2. A cutting assembly is arranged inside the work box 2 for cutting the glass. A dust suction assembly is arranged at a position corresponding to the cutting assembly inside the work box 2 for sucking the dust generated during cutting. The dust suction assembly includes a plurality of dust suction covers 9, and the plurality of dust suction covers 9 are respectively and evenly arranged inside the work box 2. A guide air pipe 7 is fixed at the top end of the dust suction cover 9. One end of the guide air pipe 7 far from the dust suction cover 9 extends to one end of the top of the work box 2. A dust suction pump 8 is fixed at one end of the top of the work box 2. The suction end of the dust suction pump 8 is fixedly connected to the guide air pipe 7. A positioning assembly is arranged at the top of the workbench frame 1 for positioning the glass during movement; a plurality of conveying rollers 4 are evenly arranged at the top of the workbench frame 1, and the plurality of conveying rollers 4 are all rotatably connected to the workbench frame 1. Through the structural design of the conveying rollers 4, it is convenient for the glass to move when moving the glass closer to the work box 2, thus saving the labor intensity of the laborers;

[0034] The cutting assembly includes an adjusting screw 10. The adjusting screw 10 is horizontally arranged at the top inner position of the work box 2. The adjusting screw 10 is rotatably connected to the work box 2. One end of the adjusting screw 10 far from the dust suction pump 8 extends to the outside of the work box 2. In order to facilitate providing power for the rotation of the adjusting screw 10, a driving motor 19 is fixed at the top end of the work box 2 far from the dust suction pump 8. The output end of the driving motor 19 is fixedly connected to the adjusting screw 10.

[0035] During work, first move the glass through the workbench frame 1 and the positioning assembly in the direction close to the work box 2. When the glass enters the work box 2 through the output port 6 and is adjusted to a suitable position for cutting, start the driving motor 19, so that the driving motor 19 drives the adjusting screw 10 to rotate. When the adjusting screw 10 rotates, it drives the moving connection seat 11 threadedly connected thereto to move along the axial direction of the adjusting screw 10. When the moving connection seat 11 moves, start the electric telescopic rod 12 at the same time, so that the electric telescopic rod 12 drives the cutting head 13 to move in the direction close to the glass. Subsequently, the glass is cut through the lateral movement of the cutting head 13. During cutting, through the dust suction pump 8, the dust suction pump 8 absorbs the dust generated during cutting through the guide air pipe 7 and the dust suction covers 9, thereby achieving the dust suction effect. And through the structural design of the work box 2, the dust will not escape to the external space during cutting, effectively improving the dust suction effect.

[0036] Further, refer toFigures 3-5 As shown, fixed rotating rollers 14 are rotatably connected to the lower inner ends of the input port 5 and the output port 6, and movable rotating rollers 15 are arranged at the upper inner ends of the input port 5 and the output port 6. Through the structural design of the fixed rotating rollers 14 and the movable rotating rollers 15, the glass can be clamped to prevent the glass from shaking. Both ends of the movable rotating roller 15 are rotatably connected with connecting sliders 16. The connecting sliders 16 are slidably connected with the working box 2. A fixed sliding rod 17 is arranged inside the connecting slider 16. The fixed sliding rod 17 is slidably connected with the connecting slider 16 and fixedly connected with the working box 2. Furthermore, through the structural design of the connecting slider 16 and the fixed sliding rod 17, when the glass enters the inside of the input port 5, it can move up and down according to the thickness of the glass, thereby improving the sealing effect of the working box 2 and being able to clamp the glass. A first spring 18 is sleeved on the outer side of the fixed sliding rod 17 and at the top position of the connecting slider 16. One end of the first spring 18 is fixedly connected with the working box 2, and the other end of the first spring 18 is fixedly connected with the connecting slider 16. Through the structural design of the first spring 18, the connecting slider 16 of the glass can be limited, so that a continuous force is applied to the connecting slider 16 in the direction close to the fixed rotating roller 14;

[0037] The positioning component includes two positioning plates 20, which are respectively symmetrically arranged at both ends of the side of the workbench frame 1 far from the working box 2. The end of the positioning plate 20 far from the working box 2 is rotatably connected with the workbench frame 1. A plurality of rotating wheels 21 are evenly rotatably connected to the side of the two working boxes 2 close to each other. Furthermore, through the structural design of the rotating wheels 21, when the glass is moved in the direction close to the working box 2, the glass can be guided and positioned while the glass is moving, without affecting the movement of the glass; A connecting rod 22 is arranged on the side of the positioning plate 20 close to the working box 2 and far from the rotating wheel 21. Connecting plates 23 are fixed at both ends of the connecting rod 22. The connecting plates 23 are fixedly connected with the positioning plate 20. A movable slider 24 is slidably connected to the outer side of the connecting rod 22. A spring telescopic rod 25 is fixed on the side of the workbench frame 1 close to the movable slider 24. The telescopic end of the spring telescopic rod 25 is rotatably connected with the movable slider 24. Through the combined structural design of the connecting rod 22, the movable slider 24 and the spring telescopic rod 25, when positioning glass of different widths, it can play an adaptive role, so as to be able to position glass of different widths.

[0038] During operation, the operator first makes the two end corners at one end of the glass contact the rotating wheels 21 respectively, and then moves the glass towards the working box 2. When the glass moves, it drives the rotating wheels 21 to rotate. At the same time, both sides of the glass squeeze the positioning plate 20 through the rotating wheels 21, causing the positioning plate 20 to rotate. When the positioning plate 20 rotates, it squeezes the spring telescopic rod 25, causing the spring telescopic rod 25 to contract. At the same time, the moving slider 24 slides on the outside of the connecting rod 22. At this time, when the spring telescopic rod 25 compresses, it generates a reaction force, which thus plays a role in pushing the glass located between the two rotating wheels 21, making the glass in the middle position between the two rotating wheels 21, and thus playing a positioning role.

[0039] Among them, as shown in Figures 7-9 In order to avoid the accumulation of relatively large debris inside the working box 2, a material discharge port is provided at the lower end inside the working box 2. A fixed box 26 is fixed at the lower end of the working box 2 and corresponding to the material discharge port. In order to facilitate the collection of debris, a collection box 27 is slidably connected to the inside of the fixed box 26; a handle 28 is fixed to the side of the collection box 27 away from the fixed box 26; two insertion holes 29 are symmetrically provided at the lower end of the side of the collection box 27 away from the fixed box 26, and an insertion component is provided at the position of the fixed box 26 corresponding to the insertion holes 29; in order to facilitate the limitation of the collection box 27 and prevent the collection box 27 from sliding out of the inside of the fixed box 26, the insertion component includes a second spring 31. The second spring 31 is provided inside the fixed box 26 and at the position corresponding to the insertion hole 29. One end of the second spring 31 is fixedly connected to the fixed box 26, and the other end of the second spring 31 is fixed with an insertion block 30. The insertion block 30 is inserted and connected to the collection box 27 through the insertion hole 29; conveyor belts 32 are provided on both sides at the top end of the material discharge port. Through the structural design of the conveyor belts 32, the debris falling on the inclined surface of the material discharge port can be conveyed into the collection box 27, and at the same time, the accumulation of debris can be avoided.

[0040] During operation, the debris with a large mass that cannot be sucked away will fall into the interior of the collection box 27 through the material discharge port to complete the collection work. When it is necessary to remove the collection box 27 from the inside of the fixed box 26, the handle 28 can be pulled, so that the handle 28 drives the collection box 27 to move away from the fixed box 26. When the collection box 27 moves, it will squeeze the plug-in block 30, causing the plug-in block 30 to move towards the second spring 31. When the plug-in block 30 moves out of engagement with the plug-in hole 29, the plug-in block 30 cancels the limit on the collection box 27, enabling the collection box 27 to be removed from the inside of the fixed box 26. Then, the debris can be concentrated for processing. When it is necessary to restore the collection box 27 to the inside of the fixed box 26, the collection box 27 is moved towards the inside of the fixed box 26. When the collection box 27 moves to a position where the plug-in hole 29 corresponds to the plug-in block 30, the plug-in block 30 is pushed into the inside of the plug-in hole 29 under the elastic action of the second spring 31, thereby completing the limit on the collection box 27 through the plug-in block 30, and the operation can be completed. Through the cooperative structural design of the fixed box 26, the collection box 27 and the plug-in assembly, the collection of debris with a large mass during cutting is realized, thereby avoiding the accumulation of debris from affecting subsequent glass processing and improving the practicability of the device.

[0041] In summary, it effectively solves the problem that in the actual use of the above patent, due to its open dust suction method, the dust and debris generated by the glass debris during processing have a large dispersion range, so the generated dust cannot be comprehensively sucked in, which will cause damage to the surrounding staff. At the same time, some debris with a large mass will fall onto the workbench surface and easily cause damage during glass processing.

[0042] Working principle:

[0043] During operation, the operator first makes the two end corners at one end of the glass contact the rotating wheels 21 respectively, and then moves the glass towards the working box 2. When the glass moves, it drives the rotating wheels 21 to rotate. At the same time, both sides of the glass will squeeze the positioning plate 20 through the rotating wheels 21, causing the positioning plate 20 to rotate. When the positioning plate 20 rotates, it will squeeze the spring telescopic rod 25, causing the spring telescopic rod 25 to contract. At the same time, the moving slider 24 will slide on the outside of the connecting rod 22. At this time, when the spring telescopic rod 25 compresses, it will generate a reaction force, which will push the glass located between the two rotating wheels 21, making the glass in the middle position between the two rotating wheels 21, thus playing a positioning role. When the glass enters the inside of the working box 2 through the input port 5 and is adjusted to the appropriate position for cutting, by starting the driving motor 19, the driving motor 19 drives the adjusting screw rod 10 to rotate. When the adjusting screw rod 10 rotates, it drives the moving connection seat 11 threadedly connected to it to move along the axial direction of the adjusting screw rod 10. When the moving connection seat 11 moves, the electric telescopic rod 12 is started at the same time, so that the electric telescopic rod 12 drives the cutting head 13 to move towards the glass. Subsequently, the glass is cut by the lateral movement of the cutting head 13. During cutting, through the dust suction pump 8, the dust suction pump 8 absorbs the dust generated during cutting through the air duct 7 and the dust suction hood 9, thus achieving the effect of dust suction. And through the structural design of the working box 2, the dust will not escape to the external space during cutting, effectively improving the dust suction effect. During cutting, the chips with larger mass that cannot be sucked away will fall into the inside of the collection box 27 through the blanking port to complete the collection work. When it is necessary to move the collection box 27 out of the inside of the fixed box 26, the handle 28 can be pulled, so that the handle 28 drives the collection box 27 to move away from the fixed box 26. When the collection box 27 moves, it will squeeze the plug-in block 30, causing the plug-in block 30 to move towards the second spring 31. When the plug-in block 30 moves out of the plug-in hole 29, the plug-in block 30 cancels the limit on the collection box 27, enabling the collection box 27 to be removed from the inside of the fixed box 26. Then the chips can be concentrated for treatment. When it is necessary to restore the collection box 27 to the inside of the fixed box 26, the collection box 27 is moved towards the inside of the fixed box 26. When the collection box 27 moves to the position where the plug-in hole 29 corresponds to the plug-in block 30, under the elastic action of the second spring 31, the plug-in block 30 is pushed into the inside of the plug-in hole 29, thereby completing the limit on the collection box 27 through the plug-in block 30, and the operation can be completed. Through the combined structural design of the fixed box 26, the collection box 27 and the plug-in assembly, it is realized that during cutting, the chips with larger mass can be collected, thus avoiding the accumulation of chips from affecting the subsequent glass processing and improving the practicality of the device.
