Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a dust removal and cutting device for assembled building panels. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated building panels mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc.

[0003] At present, in the production process of prefabricated panels, it is necessary to cut the prefabricated building panels to facilitate transportation and assembly. However, the current cutting device often only uses a cutting machine to cut horizontally, and other external methods are required to center and clamp the prefabricated building panels. In addition, a large amount of dust will be generated during the cutting process. If the dust is not handled, the diffuse dust will cause harm to the surrounding environment and human body.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1.

[0021] 4. When the cutting machine cuts the assembled building board, by setting the rotating rod, V-shaped rod and rack and other structures, the water inside the rectangular tube can be squeezed to multiple atomizing nozzles to spray out to form micron-sized water mist particles. When the diameter of the water mist particles is similar to that of the dust particles, adsorption, filtration and condensation will be formed between them. These fine water mist particles can quickly absorb various sizes of dust particles in the air, adhere to each other, aggregate, and settle under the action of their own gravity, thereby achieving the purpose of dust reduction;

[0022] 5. The V-shaped rod will also drive the slide plate to reciprocate in the vertical direction through the rectangular tube that slides through it, so the slide plate will drive multiple atomizing nozzles fixedly connected to its side wall to move in the vertical direction, thereby increasing the range of water mist particles sprayed by the atomizing nozzles, thereby improving the dust processing capability generated during the cutting process;

The sealing cover 38 can penetrate the matching hole 3 after sliding a certain distance. The inner wall of the sealing cover 38 is symmetrically provided with through holes 37. The assembled building board penetrates the through holes 37. The inner wall of the support column 2 is slidably connected with a base 30, and the base 30 is located below the conveying platform 1.

The clamping plate 36 has a concave structure, and the side wall of the second wedge block 45 is provided with a return spring 35.

[0037] One end of the return spring 35 is fixedly connected to the side wall of the back plate 33 , and the other end of the return spring 35 is fixedly connected to the side wall of the second wedge block 45 .

[0038] A mounting plate 8 is fixedly connected to the side wall of the rectangular frame 4 , a motor 9 is mounted on the mounting plate 8 , a driving shaft 7 is fixedly connected to the output end of the motor 9 , and the driving shaft 7 and the circular plate 6 are eccentrically fixedly connected.

[0039] A sliding hole 44 is formed in the inner wall of the support column 2 , and a sliding rod 43 is symmetrically fixedly connected to the side wall of the base 30 . One end of the sliding rod 43 away from the base 30 passes through the sliding hole 44 and is rotatably connected to the connecting rod 41 .

[0040] The top wall of the rectangular frame 4 is symmetrically connected to the top rod 39, the top wall of the support column 2 is provided with a groove 42, the inner wall of the groove 42 is rotatably connected to the swing rod 40, one end of the swing rod 40 is rotatably connected to the top rod 39, and the other end of the swing rod 40 is rotatably connected to the end of the connecting rod 41 away from the sliding rod 43.

[0041] The gear 16 is meshed with the rack 13 , and the first one-way pipe 28 is fixedly connected with the external water tank. The first one-way pipe 28 only allows external water to enter the rectangular tube 26 .

[0042] In the present invention, the user places the assembled building board on the conveying platform 1, and then turns on the motor 9. The output end of the motor 9 drives the driving shaft 7 fixedly connected thereto to rotate, and the driving shaft 7 drives the circular plate 6 eccentrically fixedly connected thereto to rotate. Since the circular plate 6 is embedded and rotated on the side wall of the sliding block 5, when the circular plate 6 rotates, the circular plate 6 will first drive the rectangular frame 4 to move upward in the vertical direction for a distance through the sliding block 5, and then the circular plate 6 drives the sliding block 5 to slide to the left in the horizontal direction for a distance inside the rectangular frame 4, and then the circular plate 6 drives the rectangular frame 4 to move downward in the vertical direction for a distance through the sliding block 5, and finally the circular plate 6 drives the sliding block 5 to slide to the right in the horizontal direction for a distance (such as Figure 1 and Figure 3 Then the above process is repeated continuously.

[0043] When the circular plate 6 drives the rectangular frame 4 to slide downward in the vertical direction through the sliding block 5, the rectangular frame 4 will drive the sealing cover 38 to move downward synchronously. At this time, the top rod 39 symmetrically connected to the top of the rectangular frame 4 will drive one end of the swing rod 40 connected to it for rotation to move downward, and then the other end of the swing rod 40 will drive the connecting rod 41 connected to it for rotation to move upward for a distance, and then the connecting rod 41 will drive the sliding rod 43 connected to it for rotation to move upward, so that the sliding rod 43 drives the base 30 to move upward synchronously until the bottom end of the sealing cover 38 passes through the matching hole 3 and is inserted into the matching groove 31. At this time, the sealing cover 38 forms a barrier around the assembled building board to prevent a large amount of dust from overflowing during the cutting process and causing pollution.

[0044] And in the process of the base 30 moving upward, the first wedge block 32 symmetrically fixed on the base 30 will move a distance and then slide against the second wedge block 45. Then the second wedge block 45 will drive the spring telescopic rod 34 fixedly connected to it to slide a distance, so that the clamping plate 36 fixedly connected to the other end of the spring telescopic rod 34 pushes the two sides of the prefabricated building board on the conveying platform 1 to achieve the purpose of centering and positioning, which is convenient for subsequent cutting processing. When the prefabricated building board is completed after the centering and positioning, the two second wedge blocks 45 continue to slide and will squeeze the spring telescopic rod 34. The built-in buffer spring part of the spring telescopic rod 34 is compressed, thereby clamping and fixing the two sides of the prefabricated building board.

[0045] When the cutting machine 19 is turned on, the disc-type cutting blade of the cutting machine 19 will rotate rapidly, and the sliding block 5 will drive the cutting machine 19 to move downward synchronously through the connecting frame 18 until the end of the stroke. Then, when the circular plate 6 drives the sliding block 5 to slide horizontally to the right inside the rectangular frame 4, the cutting machine 19 will also move synchronously, and then the disc-type cutting blade of the cutting machine 19 will perform horizontal cutting on the prefabricated building board.

[0046] When the connecting frame 18 drives the cutting machine 19 to cut the assembled building board, the two gears 16 arranged inside the connecting frame 18 will rotate under the action of the rack 13 meshing with it, and the gear 16 will drive the rotating rod 17 eccentrically arranged on its side wall to rotate during the rotation process, and the rotating rod 17 will drive the first rod 20 to move during the rotation process, so that the first rod 20 drives the corresponding V-shaped rod 22 to reciprocate forward and reverse for a certain angle, and the V-shaped rod 22 will drive the piston 27 to slide back and forth in a sealed manner inside the rectangular cylinder 26, and the piston 27 will pump water from the outside into the rectangular cylinder 26 through the first one-way pipe 28, and then through The second one-way tube 29 squeezes the water inside the rectangular tube 26 to multiple atomizing nozzles 25 to spray out to form micron-sized water mist particles. When the diameters of the water mist particles are similar to those of the dust particles, adsorption, filtration and condensation effects will be formed between them. These fine water mist particles can quickly absorb various sizes of dust particles in the air, adhere to and aggregate with each other, and settle under the action of their own gravity, thereby achieving the purpose of dust reduction. In addition, negative ions are generated when water mist is formed, which combine with positive ions in the dust to further accelerate the dust reduction process. At the same time, the water mist contacts the dry dust, increases the humidity of the air, and absorbs a large amount of air latent heat, which plays a cooling role.

[0047] In addition, the V-shaped rod 22 will also drive the slide plate 24 to reciprocate in the vertical direction through the rectangular tube 11 sliding therethrough. Then the slide plate 24 will drive multiple atomizing nozzles 25 fixedly connected to its side wall to move in the vertical direction, thereby increasing the range of water mist particles sprayed by the atomizing nozzles 25, thereby improving the ability to handle dust generated during the cutting process.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
