Description

Technical Field

[0001] The invention relates to the technical field of aerogel cutting and forming, in particular to a device for continuous forming and cutting of aerogel thermal insulation materials. Background Art

[0002] Aerogel refers to a nano-scale porous solid material formed by using the sol-gel method to replace the liquid phase in the gel with gas in a certain drying method; such as gelatin, gum arabic, silica gel, hair, nails, etc.; aerogel also has the properties of gel, that is, it has expansion, thixotropic and slurry-release effects.

[0003] After searching for patents, it was found that the invention patent application with the prior art publication number CN116572359B disclosed a method for preparing building thermal insulation materials by aerogelation of fly ash, aiming to solve the technical problem of cutting and forming waste in the actual installation process of the current production of only rectangular plate-type fly ash aerogelation to prepare building thermal insulation materials, including a base, an installation frame, a forming mold mechanism, a pressing mechanism, a slide rail, a linkage adjustment structure, an axial adjustment mechanism and a pump filling mechanism. The invention combines and adjusts the shape of the inner cavity of the forming mold mechanism through the linkage adjustment structure and the axial adjustment mechanism, the slide rail and the pressing mechanism, so that the fly ash aerogel batch preparation of building thermal insulation materials forming device can be adapted to form rectangular and L-shaped exterior wall thermal insulation template materials, thereby matching the cutting and forming shapes required in the actual installation of exterior wall thermal insulation template materials, and through this production method, the cutting and forming required for conventional rectangular exterior wall thermal insulation template materials is reduced to reduce cutting and forming waste.

[0004] In the process of cutting and forming aerogel thermal insulation materials, the above-mentioned existing aerogel thermal insulation material cutting and forming device is prone to breakage or cracking when subjected to external force due to the brittleness and low strength of aerogel. Traditional mechanical cutting and forming methods, such as diamond wire cutting, high-pressure gas cutting or ultrasonic cutting, often lead to local stress concentration, thereby causing the material to crack at the cutting point or bottom. Ultrafast lasers have extremely high peak power and extremely short pulse width, which can achieve "cold processing" and reduce thermal damage to materials. They are suitable for cutting and forming sensitive materials such as aerogels. However, during the laser cutting and forming process, a certain taper will be formed on both sides of the cut, which will affect the cutting and forming quality of the aerogel, thereby making the cutting and forming process of the aerogel material difficult. Therefore, based on the above search and in combination with the existing problems, a continuous cutting and forming device for aerogel thermal insulation materials is provided.

[0037] See also Figure 1 to Figure 3 A conveying cylinder 202 is rotatably mounted on the upper end of the mounting frame 101, and the conveyor belt 201 is wound on the outer wall of the conveying cylinder 202. A conveying motor 203 is fixedly mounted on the upper end of the mounting frame 101 near the conveying cylinder 202, and the output end of the conveying motor 203 is fixedly mounted on one end of the conveying cylinder 202. A supporting plate 204 is fixedly mounted on the inner wall of the mounting frame 101 near the cutting mechanism 4, and the supporting plate 204 prevents the conveyor belt 201 from bending during the cutting and molding of the aerogel by the cutting mechanism 4, resulting in inaccurate cutting and molding positions. A driven cylinder 205 is rotatably mounted on one end of the mounting frame 101 away from the supporting plate 204, and a conveying rod 206 is fixedly mounted on one end of the driven cylinder 205. The outer surface of the driven cylinder 205 is set to a rough curved surface, so that the driven cylinder 205 is driven to rotate when the conveyor belt 201 moves.

[0038] See also Figure 1 to Figure 6 The limiting mechanism 3 includes a limiting frame 301, and the limiting frame 301 is fixedly installed on the side end of the mounting frame 101 close to the cutting mechanism 4, and a limiting rod 302 is symmetrically installed on one end of the limiting frame 301 away from the mounting frame 101, and a limiting cylinder 303 is fixedly sleeved on the upper end of the limiting rod 302, and a limiting belt 304 is wound on the outer wall of the limiting cylinder 303, and the moving speed of the limiting belt 304 is the same as the moving speed of the conveyor belt 201, and a driven gear 305 is fixedly installed on the lower end of the limiting rod 302, and a driving gear 306 is fixedly sleeved on the outer wall of the conveying rod 206 close to the driven gear 305, and the driving gear 306 is meshed with the driven gear 305. When the conveying rod 206 starts to rotate, the driving gear 306 drives the driven gear 305 to start rotating, the limiting rod 302 drives the limiting cylinder 303 to rotate, and the limiting belt 304 starts to move.

[0039] See also Figure 1 to Figure 6, a plurality of limit plates 307 are fixedly installed on the outer wall of the limit belt 304, and the limit plates 307 arranged on the limit belt 304 play a role of clamping and fixing the aerogel, so that the cutting and forming device can perform continuous processing of the aerogel more conveniently, and the side ends of the limit plates 307 are provided with sliding grooves 308, and the inner walls of the sliding grooves 308 are slidably provided with limit blocks 309, and the sliding grooves 308 are provided with spring telescopic rods 310, and the spring telescopic rods 310 are fixedly installed between the limit blocks 309 and the limit plates 307. Specifically, when the limit belt 304 is opened, When the limit plate 307 starts to move, the limit plate 307 moves. When the limit plate 307 moves to the position of the limit cylinder 303, the limit plate 307 rotates around the limit cylinder 303, so that the limit plate 307 opens. Baffles 311 are fixedly installed at both ends of the limit block 309. When the baffle 311 fixedly installed by the limit block 309 makes the aerogel move to the position of the baffle 311, the limit plate 307 fixes the aerogel, and the aerogel squeezes and pushes the baffle 311 to move. The limit block 309 squeezes the compression spring telescopic rod 310, thereby pushing the aerogel to be fixed at the center position of the conveyor belt 201.

[0040] See also Figure 1 to Figure 7 The cutting mechanism 4 includes a cutting frame 401, a rotating rod 402 is fixedly installed on the upper end of the cutting frame 401, a cutting disc 403 is fixedly installed on one end of the rotating rod 402, and a special-shaped groove 404 is provided at one end of the cutting disc 403 away from the rotating rod 402. The special-shaped groove 404 is set to an elliptical shape, so that when the cutting disc 403 rotates, the cutting and forming device moves up and down with the change of the special-shaped groove 404 in the cutting disc 403. A driven disc 405 is fixedly installed at one end of the cutting frame 401 away from the cutting disc 403, and a driving disc 406 is fixedly installed at one end of the transmission rod 206 close to the driven disc 405. A belt 407 is wound between the driving disc 406 and the driven disc 405. When the transmission rod 206 rotates, the driving disc 406 causes the driven disc 405 to start rotating through the belt 407, thereby providing power for the rotation of the cutting disc 403.

[0041] See also Figure 1 to Figure 7 A slide rail 408 is fixedly installed on the side end of the cutting frame 401 close to the cutting turntable 403, and a slide block 409 is slidably installed on the end of the slide rail 408 away from the cutting frame 401. A slide frame 410 is fixedly installed on the upper end of the slide block 409. A slide rod 424 is rotatably installed on the end of the slide frame 410 close to the cutting turntable 403, and the slide rod 424 is slidably set in the special-shaped groove 404. Specifically, when the cutting turntable 403 starts to rotate, the slide rod 424 starts to slide in the special-shaped groove 404, and the slide rod 424 drives the slide frame 410 to start moving up and down. When the slide frame 410 starts to move upward, no cutting and forming is performed, and when the slide frame 410 moves downward, the aerogel is cut and formed.

[0042] See also Figures 1 to 8 A laser frame 411 is fixedly installed at one end of the sliding frame 410 away from the sliding rail 408, a rotating motor 412 is fixedly installed at the lower end of the laser frame 411, a mold disk 413 is fixedly installed at the output end of the rotating motor 412, and a mold frame 414 for placing and fixing the mold is fixedly installed at the lower end of the laser frame 411 close to the mold disk 413. Specifically, when the set mold frame 414 can fix molds of different shapes on the mold frame 414, start the rotating motor 412, and the mold disk 413 starts to rotate, the cutting mechanism 4 can fit the edges of molds of different shapes.

[0043] See also Figures 1 to 8 The mold plate 413 is provided with a welt groove 415 near the lower end of the mold frame 414, and a welt block 416 is slidably installed in the welt groove 415. The welt block 416 is rotatably installed with a laser cutter 417 near the lower end of the welt frame. The laser cutter 417 is a prior art and will not be described in detail here. A winding spring 418 is provided at the rotation connection between the laser cutter 417 and the welt block 416. The winding spring 418 provided above enables the laser cutter 417 to start rotating a certain angle when the welt block 416 moves, and the angle is small. The mold frame 41 4 is fixedly installed with a retractable fixed telescopic rod 419 at the lower end, and a fixed telescopic clamp 420 is fixedly installed at the output end of the fixed telescopic rod 419. Specifically, when replacing aerogels of different thicknesses, the fixed telescopic clamp 420 fixes the aerogels of different thicknesses on the mold frame 414, and the control rope drives the edge block 416 to start moving, so that the laser cutter 417 rotates a certain angle, so that when the laser cuts the aerogel, the taper generated by the aerogel is matched with the angle of the laser cutter 417, thereby improving the cutting and molding quality of the aerogel.

[0044] See also Figures 1 to 8 , a vent pipe 421 is fixedly installed at the output end of the fixed telescopic clamp 420, and the above-mentioned vent pipe 421 is a retractable and bendable pipe, so that the edge block 416 can be fitted on the edge of the mold, and the force is not enough to push the laser cutter 417 to rotate, and a pneumatic telescopic rod 422 is fixedly installed at one end of the vent pipe 421 away from the fixed telescopic clamp 420, and the pneumatic telescopic rod 422 is rotatably installed on the side end of the edge block 416, and a push rod 423 is rotatably installed at the output end of the pneumatic telescopic rod 422, and the push rod 423 is rotatably installed on the side end of the laser cutter 417. Specifically, when the fixed telescopic clamp 420 is extended, the pneumatic telescopic rod 422 begins to contract, but the negative pressure in the pneumatic telescopic rod 422 can only drive the laser to rotate a small angle under the elastic force of the winding spring 418. When processing aerogels of different thicknesses, the inclination angle of the laser cutter 417 will change, thereby avoiding the generation of taper when the laser cuts the aerogel.

[0045] The working principle of the present invention is as follows: when the aerogel needs to be cut and formed, the mold is placed in the mold frame 414, and the mold is fixed by using the fixed telescopic clamp 420. When the fixed telescopic clamp 420 is extended, the pneumatic telescopic rod 422 begins to shrink. However, the negative pressure in the pneumatic telescopic rod 422 can only drive the laser to rotate a small angle under the elastic force of the winding spring 418. When processing aerogels of different thicknesses, the inclination angle of the laser cutter 417 will change, thereby avoiding the generation of taper when the laser cuts and forms the aerogel;

[0046] The aerogel is placed on the surface of the conveyor belt 201, and the conveying motor 203 is started. The conveyor drum 202 drives the conveyor belt 201 to start moving. The conveyor belt 201 moves and the driven drum 205 drives the conveying rod 206 to start rotating. The limiting belt 304 starts to move, so that the limiting plate 307 and the baffle 311 fix the aerogels one by one in sequence, so that the continuous processing of the aerogel is faster.

[0047] At the same time, when the conveying rod 206 rotates, the active disk 406 causes the driven disk 405 to start rotating through the belt 407, and the cutting turntable 403 starts to rotate, causing the laser cutter 417 to start moving up and down. When the aerogel moves below the laser cutter 417, the laser cutter 417 just moves to the bottom, the conveyor belt 201 stops moving, and the rotating motor 412 is started. The laser cutter 417 moves along the edge of the mold, so that the laser cutter 417 cuts and shapes the aerogel, thereby making it more convenient to process the aerogel into different shapes.

[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 in the present invention, which should be covered by the protection scope of the present invention.
