[0002] The dried and shaped gypsum boards are cut into different sizes according to production needs using a cutting machine.

[0041] 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.

[0042] like Figure 1 , Figure 2 As shown, the present invention provides a negative pressure synchronous slag collection gypsum board cutting device, comprising:

[0043] First cutting blade ruler 1;

[0044] The second cutting blade 2 is arranged opposite to the first cutting blade 1, and a cutting area is formed between the first cutting blade 1 and the second cutting blade 2;

[0045] The cutting power device 3 is connected to the first cutting blade 1 and the second cutting blade 2. The cutting power device 3 is used to control the first cutting blade 1 and the second cutting blade 2 to move towards each other or away from each other.

[0046] Conveying mechanism 4, through which gypsum board passes from the cutting area;

[0047] The sealing cover 5 is respectively installed on the outer wall of the first cutting blade 1 and the second cutting blade 2. The side of the sealing cover 5 near the gypsum board is in close contact with the surface of the gypsum board.

[0048] The buffer box 6 is located on the inner wall of the sealing cover 5;

[0049] The negative pressure device 7 has a suction port connected to the sealing cover 5 and a discharge port connected to the buffer box 6.

[0050] In this invention, a sealing cover 5 is provided on the outer wall of the first cutting blade 1 and the second cutting blade 2. The sealing cover 5 is in close contact with the gypsum board it passes through to form a relatively sealed environment. The first cutting blade 1 and the second cutting blade 2 complete the cutting action inside the sealing cover 5. At the same time, the negative pressure device 7 is activated to attract and collect the dust and waste particles generated during cutting into the buffer box 6. The cutting process and the collection process are carried out simultaneously, simplifying the operation process. At the same time, the sealed environment formed by the sealing cover 5 can lock the dust inside the sealing cover 5, minimizing the pollution of the working environment.

[0051] In this design, the buffer box 6 is placed inside the sealing cover 5, and the suction position and discharge position of the negative pressure device 7 are close to each other, reducing the negative pressure requirement of the negative pressure device 7. The negative pressure device 7 can be selected from existing technologies such as vacuum pumps or negative pressure fans.

[0052] like Figure 1 As shown, the first cutting blade 1 and the second cutting blade 2 are respectively connected to a rotating shaft 8, and the cutting power device 3 drives the first cutting blade 1 and the second cutting blade 2 to rotate through the rotating shaft 8;

[0053] When the cutting power device 3 drives the first cutting blade 1 and the second cutting blade 2 to rotate towards each other to the cutting area, the blade surfaces of the first cutting blade 1 and the second cutting blade 2 contact or even overlap, thereby cutting the gypsum board. During the time it takes for the cutting power device 3 to drive the first cutting blade 1 and the second cutting blade 2 to rotate one revolution, the length of the gypsum board passing through the cutting area is exactly the size required for production. The first cutting blade 1 and the second cutting blade 2 can be driven by the same cutting power device 3, or they can each be driven by a separate cutting power device 3.

[0054] A gas slip ring 9 is installed on the rotating shaft 8. An air inlet pipe 10 is provided at the air inlet of the gas slip ring 9. The end of the air inlet pipe 10 away from the gas slip ring 9 is connected to the sealing cover 5.

[0055] A feed pipe 11 is provided at the outlet of the gas slip ring 9. The end of the feed pipe 11 away from the gas slip ring 9 is connected to the suction port of the negative pressure device 7. A discharge pipe 12 is connected at the discharge port of the negative pressure device 7. The end of the discharge pipe 12 away from the negative pressure device 7 is connected to the buffer box 6.

[0056] The gas slip ring 9 can establish a reliable gas channel between the rotating shaft 8 and the negative pressure device 7, and can effectively avoid pipe entanglement or leakage caused by rotation. By installing the rotor inside the gas slip ring 9 on the rotating shaft 8, and connecting the external stator to the negative pressure device 7 and the sealing cover 5 respectively, dust and waste particles enter the air inlet pipe 10, feed pipe 11, and discharge pipe 12 in sequence, and finally enter the buffer box 6.

[0057] Since the buffer box 6 is located inside the sealing cover 5, if the buffer box 6 is full during the process of collecting dust and waste particles under negative pressure, it is difficult to clean the collected dust and waste particles inside the buffer box 6 in time. In order to clean and unclog the dust and waste particles inside the buffer box 6 in time, a storage box 13 is set near the outside of the sealing cover 5. The end of the buffer box 6 away from the discharge pipe 12 is connected to the storage box 13.

[0058] Specifically, a conveying pipe 26 is installed on the outer wall of the buffer box 6. The end of the conveying pipe 26 away from the buffer box 6 passes through the sealing cover 5 and is connected to a material passage pipe 27. The end of the material passage pipe 27 is connected to the storage box 13.

[0059] After dust and waste particles enter the buffer box 6 through the discharge pipe 12, they enter the conveying pipe 26 and the feeding pipe 27 in sequence under the action of compression and negative pressure, and finally enter the external storage box 13. In order to accommodate more dust and waste particles, the capacity of the storage box 13 is much larger than that of the buffer box 6. During the process of collecting dust and waste particles under negative pressure, the buffer box 6 can be prevented from being full by cleaning or replacing the storage box 13.

[0060] The bodies of the buffer box 6 and the storage box 13, as well as the interfaces with the pipes, are sealed to minimize the leakage of dust or even waste particles. Since the buffer box 6 is installed inside the sealing cover 5, the sealing of the body of the buffer box 6 and the interface with the pipes also minimizes the risk of the negative pressure device 7 sucking away the dust and waste particles in the buffer box 6 through the gas slip ring 9.

[0061] like Figure 3 , Figure 5 As shown, if the dust and waste particles in the buffer box 6 enter the storage box 13 only under the action of squeezing and negative pressure, the required negative pressure will be relatively large. In order to reduce the negative pressure requirement, a material transfer mechanism 14 is provided in the buffer box 6 below the position where the discharge pipe 12 is connected. The material transfer mechanism 14 is arranged along the length of the buffer box 6. The dust and waste particles in the discharge pipe 12 enter the buffer box 6 and fall directly onto the material transfer mechanism 14 below, and are transported to the conveying pipe 26 by the material transfer mechanism 14. In order to buffer more dust and waste particles, the buffer box 6 is arranged along the length of the sealing cover 5.

[0062] The material conveying mechanism 14 includes a drive roller 1401, a driven roller 1402, several idlers 1403, a conveyor belt 1404, and a drive structure 15;

[0063] The ends of the drive roller 1401 and the driven roller 1402 are rotatably mounted on the inner wall of the buffer box 6, and the ends of several idlers 1403 are fixedly mounted on the inner wall of the buffer box 6. The conveyor belt 1404 is sequentially sleeved on the outer wall of the drive roller 1401, the driven roller 1402, and the several idlers 1403.

[0064] One end of the drive roller 1401 passes through the side wall of the buffer box 6 and is connected to the drive structure 15.

[0065] The drive structure 15 drives the drive roller 1401 to rotate. The drive roller 1401 drives the conveyor belt 1404 to rotate through the friction between itself and the inner wall of the conveyor belt 1404. The driven roller 1402 and several idlers 1403 are used to support and tension the conveyor belt 1404 and fix the transport direction of the conveyor belt 1404. The edge of the conveyor belt 1404 fits tightly against the inner wall of the buffer box 6 to prevent dust and waste particles from falling from the edge of the conveyor belt 1404 to the bottom of the buffer box 6 during transportation. The length of the drive belt is as close as possible to the length of the buffer box 6.

[0066] After dust and waste particles enter the buffer box 6 from the discharge pipe 12, they fall directly onto the conveyor belt 1404 below. The drive structure 15 drives the conveyor belt 1404 to rotate, transporting the dust and waste particles to the conveying pipe 26. Once the conveying pipe 26 is full of dust and waste particles, subsequent dust and waste particles squeeze the existing particles in the conveying pipe 26, forcing them into the feed pipe 27, and then into the storage box 13. To facilitate the flow of dust and waste particles from the feed pipe 27 into the storage box 13, as follows... Figure 1 As shown, the feed pipe 27 can be installed vertically.

[0067] If the material transfer mechanism 14 and the rotating shaft 8 are driven by independent structures, when the cutting power device 3 drives the rotating shaft 8 to rotate faster, the rotating shaft 8 drives the first cutting blade 1 and the second cutting blade 2 to increase the cutting speed, thereby increasing the amount of dust and waste particles. In order to prevent blockage in the buffer box 6, the dust and waste particles need to be transferred out in time. However, the independent design makes it impossible for the first cutting blade 1, the second cutting blade 2 and the material transfer mechanism 14 to work in a completely synchronous manner. Therefore, the linkage design of the first cutting blade 1, the second cutting blade 2 and the material transfer mechanism 14 in this invention can ensure that when the first cutting blade 1 and the second cutting blade 2 accelerate their rotation, the material transfer mechanism 14 also accelerates its rotation speed, thereby speeding up the transfer of dust and waste particles out of the buffer box 6, and avoiding blockage in the buffer box 6 due to the relatively low transfer speed of the material transfer mechanism 14 caused by the increase in the amount of dust and waste particles.

[0068] like Figure 1 As shown, in order to make the material transfer mechanism 14 work synchronously with the rotating shaft 8, the present invention makes the following design. Specifically, the drive structure 15 includes a worm gear 1501, a worm 1502, an intermediate gear 1503, and a ring gear 1504.

[0069] The worm gear 1501 is connected to the end of the drive roller 1401. The worm gear 1501 meshes with the worm 1502. The intermediate gear 1503 is connected to the shaft end of the worm gear 1501. The intermediate gear 1503 meshes with the ring gear 1504. The ring gear 1504 is sleeved on the outer wall of the rotating shaft 8.

[0070] The power cut-off device 3 drives the rotating shaft 8 and the ring gear 1504 to rotate. The ring gear 1504 drives the intermediate gear 1503 and the worm gear 1502 to rotate. The worm gear 1502 drives the worm wheel 1501 to rotate. The worm wheel 1501 drives the drive roller 1401 to rotate, which in turn drives the conveyor belt 1404 to rotate.

[0071] like Figure 1 As shown, in order to both fix the intermediate gear 1503 and the worm 1502 and allow the worm wheel 1501 and the worm 1502 to rotate, a mounting hole is provided on the inner wall of the sealing cover 5. A bearing 16 is installed in the mounting hole, and the end of the worm 1502 passes through the intermediate gear 1503 and is connected to the inner ring of the bearing 16.

[0072] like Figure 1 , Figure 2 As shown, in order to fix the rotating shaft 8, a mounting bracket 17 is installed near the side wall of the sealing cover 5. The side wall of the sealing cover 5 opposite to the mounting bracket 17 is provided with through holes 18. One end of the rotating shaft 8 passes through the through hole 18 and is rotatably mounted on the mounting bracket 17. The other end of the rotating shaft 8 passes through the through hole 18 and is connected to the cutting power device 3.

[0073] The rotating shaft 8 rotates while the sealing cover 5 remains stationary. In order to fix the sealing cover 5, an insert ear 19 is provided on the outer wall of the sealing cover 5, and a pin ear 20 is provided on the mounting bracket 17. The insert ear 19 and the pin ear 20 are connected by bolts and nuts.

[0074] like Figure 4 As shown, the ends of the rotating shaft 8 pass through the sealing cover 5 respectively. If the sealing cover 5 is fixedly installed on the outer wall of the first cutting blade 1 and the second cutting blade 2, it will be difficult to inspect the components inside the sealing cover 5 (the first cutting blade 1, the second cutting blade 2, the material transfer mechanism 14, etc.). In order to facilitate the inspection of the components inside the sealing cover 5, the present invention designs the sealing cover 5 as a detachable cover structure. Specifically, the sealing cover 5 includes a first splicing cover 21 and a second splicing cover 22 formed by penetrating and dividing along its own length direction, and the dividing position is far away from the installation position of the buffer box 6. The first splicing cover 21 and the second splicing cover 22 divide the through hole 18 into two along the diameter direction of the through hole 18.

[0075] A fixing ear 23 is installed on the side wall of the first splicing cover 21, and a connecting ear 24 is installed on the outer wall of the second splicing cover 22. Both the fixing ear 23 and the connecting ear 24 have threaded holes 25 through them. Bolts can be threaded into the threaded holes 25. The fixing ear 23 and the connecting ear 24 are connected by bolts and nuts.

[0076] When the sealing cover 5 needs to be removed, first remove the bolts on the fixing ear 23 and the connecting ear 24, then remove the second splicing cover 22. After the second splicing cover 22 is removed, a notch is formed on the first splicing cover 21 that allows the rotating shaft 8 and the first splicing cover 21 to move relative to each other. Then move the first splicing cover 21 away from the rotating shaft 8 until the first splicing cover 21 is removed.

[0077] The sealing cover 5 is set along the length of the rotating shaft 8, so the sealing cover 5 needs to be cut along its own length to remove it;

[0078] The buffer box 6 is installed on the inner wall of the sealing cover 5. In order to prevent the buffer box 6 from being divided, the division position should be far away from the installation position of the buffer box 6.

[0079] The sealing cover 5 is connected to the rotating shaft 8 through the through hole 18. Therefore, the dividing position of the first splicing cover 21 and the second splicing cover 22 requires dividing the through hole 18 in two along its diameter direction in order to separate the rotating shaft 8 from the first splicing cover 21 and the second splicing cover 22.

[0080] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
