Description

Technical Field

[0001] This invention relates to the field of rock wool insulation board production technology, specifically to a fiberglass cement substrate fabrication device for rock wool insulation board production. Background Technology

[0002] Rock wool insulation boards are made primarily from basalt and other natural minerals. After melting, the basalt melt is spun into discontinuous fibers of 4–7 μm using an internationally advanced four-roller centrifugal spinning process. A certain amount of binder, dust-proofing oil, and water-repellent agent are then added to the rock wool fibers. After sedimentation, curing, and cutting processes, a series of products with different densities are manufactured according to different applications. Rock wool insulation boards are suitable for thermal insulation and sound insulation of industrial equipment, buildings, and ships.

[0003] During the production of rock wool insulation boards, a fiberglass cement substrate needs to be adhered to both sides of the rock wool to increase the insulation effect and adhesion strength to the wall. In the production process of the fiberglass cement substrate on the surface of the rock wool insulation board, the cement-based coating is usually applied by scraping the cement slurry evenly onto the surface of the fiberglass cloth directly with a scraper. This production method results in poor roughness of the cement base on the surface of the fiberglass cement substrate, which leads to poor adhesion of the rock wool insulation board after production. Summary of the Invention

[0004] The purpose of this invention is to provide a fiberglass cement substrate fabrication device for the production of rock wool insulation boards. This device can effectively spray the surface of the fiberglass cloth, greatly improving the spraying effect on the cement base on the surface of the fiberglass cloth, thereby increasing the roughness of the cement base on the surface of the fiberglass cement substrate after production and improving the bonding strength between the fiberglass substrate and the wall.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A fiberglass cement substrate feeding device for rock wool insulation board production includes an installation frame, a placement rack fixedly connected inside the installation frame, multiple guide rollers fixedly connected inside the installation frame, a feeding mechanism disposed above the guide rollers, and a feeding mechanism fixedly connected to the installation frame via a pipe.

[0007] As a further aspect of the present invention: the fabric-laying mechanism includes two first threaded rods rotatably connected to the mounting frame. A first mounting block is threadedly fitted onto the outer surface of each first threaded rod. A guide rod, fixedly connected to the mounting frame, is slidably connected to the inner surface of the first mounting block. Two first nozzles are rotatably connected to the mounting block. A first transmission mechanism is drively connected to the outer surface of each first threaded rod. A first motor is fixedly connected to one side of the mounting frame. A second threaded rod, rotatably connected to the mounting frame, is fixedly connected to the output end of the first motor via a coupling. A second mounting block is threadedly fitted onto the outer surface of the second threaded rod. Two second nozzles are rotatably connected to the second mounting block. A second transmission mechanism, connected to the mounting frame, is drively connected to the outer surfaces of both the first and second nozzles. A connecting bend is rotatably connected to the top of each of the first and second nozzles. The connecting bend on the first nozzle is fixedly connected to the first mounting block, and the connecting bend on the second nozzle is fixedly connected to the second mounting block. A feed pipe, fixedly connected to the mounting frame, is fixedly connected to the top of the connecting bend via a flexible hose. The outer surface of the feed pipe is connected to a feeding mechanism via a pipe.

[0008] As a further aspect of the present invention: the first transmission mechanism includes a second motor fixedly connected to the mounting frame, the output end of the second motor is fixedly connected to a first rotating shaft via a coupling, a first gear is fixedly sleeved on the outer surface of the first rotating shaft, and a second gear fixedly sleeved on the outer surface of the first gear is meshed with the first threaded rod.

[0009] As a further aspect of the present invention: the second transmission mechanism includes a transmission gear that is fixedly sleeved with both the first nozzle and the second nozzle, and a transmission rack that meshes with the transmission gear is fixedly connected inside the mounting frame.

[0010] As a further aspect of the present invention: the feeding mechanism includes a feeding box fixedly connected to the mounting frame, a spraying machine is fixedly connected to the bottom of the feeding box via a pipe, the output end of the spraying machine is connected to the conveying pipe via a pipe, and a stirring mechanism is provided inside the feeding box.

[0012] As a further aspect of the present invention: a spiral rod is fixedly connected to the bottom end of the second rotating shaft.

[0013] The beneficial effects of this invention are:

[0014] (1) By placing the fiberglass cloth ring into the mounting frame, and then pulling the fiberglass cloth on the guide roller at a uniform speed, the first threaded rod is driven to rotate by the first transmission mechanism. The first threaded rod drives the first mounting block and the first nozzle to move left and right, forming an inclined spraying. Then, the second threaded rod is driven to rotate by the first motor. The second threaded rod drives the second mounting block and the second nozzle to move left and right, forming a horizontal spraying. This forms a cross spraying, which increases the complexity of the spraying. Then, the first nozzle and the second nozzle are driven to rotate by the cooperation of the second transmission mechanism to increase the spraying range, thereby greatly improving the spraying effect on the fiberglass cloth, thereby increasing the roughness of the surface of the fiberglass cement substrate after production, and thus improving the adhesion between the surface and the wall.

[0015] (2) The second shaft is driven to rotate by the third motor. The second shaft drives the stirring shaft and stirring rod to rotate through the third gear and the fourth gear. At the same time, the second shaft drives the screw rod to rotate, moving the cement slurry in the feed box up and down, thereby effectively mixing the raw materials in the feed box, preventing the raw materials in the feed box from settling, and improving the uniformity of the sprayed cement slurry.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 As shown, this invention is a fiberglass cement substrate fabrication device for producing rock wool insulation boards. It includes an installation frame 1, a placement rack 2 fixedly connected inside the installation frame 1, and multiple guide rollers 3 fixedly connected inside the installation frame 1. A fabrication mechanism is positioned above the guide rollers 3, and the fabrication mechanism is fixedly connected to a feeding mechanism fixedly connected to the installation frame 1 via a pipe. A roll of fiberglass fabric is placed onto the placement rack 2 inside the installation frame 1 and fixed, then guided by the guide rollers 3, and pulled by a feeding machine. Simultaneously, the fabrication mechanism and the feeding mechanism work together to uniformly and thoroughly spray cement base onto the surface of the fiberglass fabric, thereby increasing the surface roughness of the produced fiberglass cement substrate and improving the adhesion between the surface and the wall.

[0024] The fabric-making mechanism includes two first threaded rods 11 rotatably connected to the mounting frame 1. A first mounting block 12 is threaded onto the outer surface of each first threaded rod 11. A guide rod, fixedly connected to the mounting frame 1, is slidably connected to the inner surface of the first mounting block 12. Two first nozzles 13 are rotatably connected to the mounting block 1. A first transmission mechanism is drively connected to the outer surface of each first threaded rod 11. A first motor 14 is fixedly connected to one side of the mounting frame 1. The output end of the first motor 14 is fixedly connected to a second threaded rod 15 rotatably connected to the mounting frame 1 via a coupling. The outer surface of the first nozzle 13 is threaded with a second mounting block 16. Two second nozzles 17 are rotatably connected to the second mounting block 16. The outer surfaces of both the first nozzle 13 and the second nozzles 17 are driven by a second transmission mechanism connected to the mounting frame 1. The top ends of both the first nozzle 13 and the second nozzles 17 are rotatably connected to a connecting bend 18. The connecting bend 18 on the first nozzle 13 is fixedly connected to the first mounting block 12, and the connecting bend 18 on the second nozzle 17 is fixedly connected to the second mounting block 16. The top of the connecting bend 18 is fixedly connected to a material conveyor that is fixedly connected to the mounting frame 1 via a flexible hose. Pipe 19, the outer surface of the conveying pipe 19 is connected to the feeding mechanism through a pipe, and the first transmission mechanism drives the first threaded rod 11 to rotate back and forth. The first threaded rod 11 drives the first mounting block 12 to move left and right. The first mounting block 12 drives the first nozzle 13 to move left and right. Since the first nozzle 13 is designed to be perpendicular to the mounting frame 1, and because the fiberglass cloth is continuously conveyed, the first nozzle 13 sprays the cement base onto the surface of the fiberglass cloth at an angle. At the same time, the first motor 14 drives the second threaded rod 15 to rotate back and forth. (The first motor 14 is controlled by a PLC programming program, which can control the first...) The motor 14 rotates in both directions and at different angles. The second threaded rod 15 drives the second mounting block 16 to move back and forth. The second mounting block 16 drives the second nozzle 17 to move back and forth. Due to the inclined design of the second threaded rod 15 and the mounting frame 1, and the horizontal spraying of the cement-based nozzle on the fiberglass cloth during the conveying process, the spraying on the fiberglass cloth is achieved as an inclined horizontal cross-spraying, making the surface spraying texture more complex, thus greatly improving the spraying effect on the fiberglass cloth. At the same time, the second transmission mechanism drives the first nozzle 13 and the second nozzle 17 to rotate, increasing the spraying range.

[0025] The first transmission mechanism includes a second motor 21 fixedly connected to the mounting frame 1. The output end of the second motor 21 is fixedly connected to a first rotating shaft 22 via a coupling. A first gear 23 is fixedly sleeved on the outer surface of the first rotating shaft 22. A second gear 24 is meshed with the outer surface of the first gear 23 and fixedly sleeved on the first threaded rod 11. The second motor 21 is controlled by a PLC programming program, which can control the second motor 21 to rotate in both directions and the rotation angle. The second motor 21 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the first threaded rod 11 to rotate in both directions via the first gear 23 and the second gear 24.

[0026] The second transmission mechanism includes a transmission gear 25 that is fixedly sleeved with both the first nozzle 13 and the second nozzle 17. A transmission rack 26 that meshes with the transmission gear 25 is fixedly connected inside the mounting frame 1. During the process of the first mounting block 12 and the second mounting block 16 moving left and right through the first threaded rod 11 and the second threaded rod 15, the transmission gear 25 on the first nozzle 13 and the second nozzle 17 meshes with the transmission rack 26, causing the transmission gear 25 to rotate. The transmission gear 25 then causes the first nozzle 13 and the second nozzle 17 to rotate.

[0027] The feeding mechanism includes a feeding box 31 fixedly connected to the mounting frame 1. A sprayer 32 is fixedly connected to the bottom of the feeding box 31 through a pipe. The output end of the sprayer 32 is connected to the conveying pipe 19 through a pipe. A stirring mechanism is provided inside the feeding box 31. The cement slurry in the feeding box 31 is pumped into the conveying pipe 19 through the pipe and the sprayer 32. Then, the cement slurry is passed into the first nozzle 13 and the second nozzle 17 for spraying through the conveying pipe 19 and the hose.

[0028] The stirring mechanism includes a third motor 41 fixedly connected to the feed box 31. The output end of the third motor 41 is fixedly connected to a second rotating shaft 42 via a coupling. A third gear 43 is fixedly sleeved on the outer surface of the second rotating shaft 42. The outer surface of the third gear 43 is meshed with multiple fourth gears 44. A stirring shaft 45, which is rotatably connected to the feed box 31, is fixedly sleeved in the middle of the fourth gear 44. Multiple stirring rods 46 are fixedly connected to the outer surface of the stirring shaft 45. A spiral rod 47 is fixedly connected to the bottom end of the second rotating shaft 42. The third motor 41 drives the second rotating shaft 42 to rotate. The second rotating shaft 42 drives the stirring shaft 45 to rotate through the third gear 43 and the fourth gears 44. The stirring shaft 45 drives the stirring rods 46 to rotate. The stirring rods 46 stir the raw materials in the feed box 31 to prevent the cement slurry in the feed box 31 from settling, which would result in uneven spraying of cement slurry. At the same time, the spiral rod 47 drives the cement slurry in the feed box 31 to move up and down, thereby effectively mixing the raw materials in the feed box 31 and preventing the raw materials in the feed box 31 from settling.

[0029] The working principle of this invention is as follows: A roll of fiberglass cloth is placed and fixed onto the mounting frame 2 within the mounting frame 1. It is then guided by the guide roller 3 and pulled by the pulling machine. The first transmission mechanism drives the first threaded rod 11 to rotate reciprocally. The first threaded rod 11 drives the first mounting block 12 to move left and right reciprocally. The first mounting block 12 drives the first nozzle 13 to move left and right. Because the first nozzle 13 is designed perpendicular to the mounting frame 1, and because the fiberglass cloth is continuously conveyed, the first nozzle 13 sprays the cement-based coating onto the fiberglass cloth surface at an angle. Simultaneously, the first motor 14 drives the second threaded rod 15 to rotate reciprocally. (The first motor 14 is controlled by a PLC program, allowing for forward and reverse rotation.) (and the angle of rotation) The second threaded rod 15 drives the second mounting block 16 to move back and forth left and right, and the second mounting block 16 drives the second nozzle 17 to move back and forth left and right. Due to the inclined design of the second threaded rod 15 and the mounting frame 1, and the horizontal spraying of the cement-based nozzle on the fiberglass cloth during the conveying process, the spraying on the fiberglass cloth is achieved as an inclined horizontal cross spraying, making the surface spraying texture more complex, thereby greatly improving the spraying effect on the fiberglass cloth. At the same time, the second transmission mechanism drives the first nozzle 13 and the second nozzle 17 to rotate, increasing the spraying range, thereby greatly improving the cement-based spraying effect on the surface of the fiberglass cloth, thereby increasing the roughness of the surface of the fiberglass cement substrate after production and improving the adhesion between the surface and the wall.

[0030] The third motor 41 drives the second rotating shaft 42 to rotate. The second rotating shaft 42 drives the stirring shaft 45 to rotate through the third gear 43 and the fourth gear 44. The stirring shaft 45 drives the stirring rod 46 to rotate. The stirring rod 46 stirs the raw materials in the feed box 31 to prevent the cement slurry in the feed box 31 from settling, which would cause the sprayed cement slurry to be uneven. At the same time, the screw rod 47 drives the cement slurry in the feed box 31 to move up and down, thereby effectively mixing the raw materials in the feed box 31 and preventing the raw materials in the feed box 31 from settling.

[0031] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
