Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber felt net production, in particular to a spraying device in glass fiber felt production. Background Art

[0002] Glass fiber mat is a fiber product composed of continuous filaments or chopped filaments that are non-directionally combined by chemical binders or mechanical action. During the production process of glass fiber mat, a spraying device is used to evenly spray the resin liquid on the glass fiber mat. During the spraying process, the prepared resin liquid is evenly sprayed on one side of the glass fiber mat material to mix the resin liquid with the glass fiber mat.

[0003] In the prior art, the glass fiber felt mesh is usually transported horizontally, and then the nozzle for spraying the resin liquid is sprayed vertically onto the glass fiber felt mesh. However, after the resin liquid soaks the glass fiber felt mesh, the resin liquid will fall to one side of the glass fiber felt mesh due to gravity and the impact of the spray, and the resin liquid cannot be evenly coated on the glass fiber felt mesh, affecting the tensile strength and other mechanical properties of the glass fiber felt mesh after subsequent treatment, and affecting the processing quality of the glass fiber felt mesh. At the same time, after the resin liquid is sprayed on the glass fiber felt mesh, a certain pressure needs to be applied to the glass fiber felt mesh in the next step to help the resin liquid better penetrate and adhere to the glass fiber felt mesh. Then, the sprayed fiber mesh needs to be heated and dehumidified, which still requires another step to complete. The processing device of the heating and dehumidification device is relatively long, which increases the length of the glass fiber felt mesh production device and greatly occupies the factory processing space.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figures 1 to 6As shown, in this embodiment, the spraying device in the production of glass fiber mat includes a bracket 1, a guide roller 2 is rotatably installed on the top of one end of the bracket 1 through a bearing, a feeding motor 3 is fixedly installed on one side of the bracket 1 corresponding to the position of the guide roller 2, and the output end of the feeding motor 3 is fixedly connected to one end of the guide roller 2, and a first extrusion heating tube 4 and a second extrusion heating tube 5 are respectively installed on the bottom of the end of the bracket 1 away from the guide roller 2, and the first extrusion heating tube 4 and the second extrusion heating tube 5 can rotate synchronously in opposite directions, and the glass fiber mat is located between the first extrusion heating tube 4 and the second extrusion heating tube 5, and the first extrusion heating tube 4 and the second extrusion heating tube 5 are used to transport the glass fiber mat. An air inlet pipe 6 is rotatably installed between the ends of the first extrusion heating tube 4 and the second extrusion heating tube 5 through a mechanical seal, and the air inlet pipe 6 is connected to the air outlet end of the hot air blower. Exhaust holes 7 are equidistantly provided on the outer sides of the first extrusion heating tube 4 and the second extrusion heating tube 5. The hot air produced by the hot air blower will enter the interior of the first extrusion heating tube 4 and the second extrusion heating tube 5 through the air inlet pipe 6 and be discharged from the exhaust hole 7. The glass fiber felt mesh sprayed with resin liquid can be preheated while the first extrusion heating tube 4 and the second extrusion heating tube 5 extrude the glass fiber felt mesh. A storage pipe 8 is installed in the middle position of the bracket 1, and one end of the storage pipe 8 is connected to a feed pipe 9, and the feed pipe 9 is connected to a material storage tube 8 for storing the material. The pressure tanks of the resin liquid are connected to each other, an electromagnetic pump is installed in the middle of the feed pipe 9, and a nozzle 10 is fixedly installed at an equal distance in the middle of the storage pipe 8. The resin liquid in the pressure tank enters the interior of the storage pipe 8 through the feed pipe 9 through the electromagnetic pump and is sprayed out from the nozzle 10, so as to spray the surface of the glass fiber felt net with the resin liquid. The angle between the spray position of the nozzle 10 and the conveying plane of the glass fiber felt net is forty-five degrees. When the surface of the glass fiber felt net is sprayed with the resin liquid, the spray position of the nozzle 10 has a certain angle with the surface of the glass fiber felt net, so that the resin liquid sprayed from the nozzle 10 can be blown obliquely to the interior and surface of the glass fiber felt net, and the resin liquid on the surface of the upper part of the glass fiber felt net can be tilted into The glass fiber felt mesh is then injected into the interior and surface of the next part of the glass fiber felt mesh, and the glass fiber felt mesh can be sprayed as a whole. After the spraying operation, the glass fiber felt mesh will be transported to between the first extrusion heating tube 4 and the second extrusion heating tube 5, and the hot air produced by the hot air blower will enter the interior of the first extrusion heating tube 4 and the second extrusion heating tube 5 through the air inlet pipe 6 and be discharged from the exhaust hole 7.

The length of the heating and dehumidification device can be shortened, thereby reducing the space occupied by the glass fiber felt production device and improving the processing efficiency of the glass fiber felt mesh.

[0025] like Figures 1 to 6As shown, mounting blocks 11 are symmetrically fixedly installed at both ends of the material storage tube 8, and first limiting rods 12 are symmetrically fixedly installed at both ends of the mounting blocks 11. First limiting holes 13 are provided at the positions of the first limiting rods 12 on both sides of the bracket 1, and the first limiting holes 13 are slidably connected with the first limiting rods 12. A mounting frame 14 is fixedly installed at the middle of the material storage tube 8, and a guide groove 15 is provided on the top of the mounting frame 14. A fixing frame 16 is fixedly installed at the middle of the bracket 1, and a moving motor 17 is fixedly installed at the middle of the fixing frame 16.

[0026] The rotating plate 18 is driven to rotate by the mobile motor 17, and the guide rod 19 will make a circular motion along the central axis of the mobile motor 17. The first limiting rod 12 installed at both ends of the storage tube 8 will be driven to slide back and forth inside the first limiting hole 13 through the squeezing of the guide groove 15 by the guide rod 19, so that the injection position of the nozzle 10 can be adjusted at any time.

[0027] like Figures 1 to 6 As shown, a first pulley 20 is fixedly installed at one end of the guide roller 2, and both ends of the first extrusion heating tube 4 are rotatably installed on the bracket 1 through bearings. A second pulley 21 is fixedly installed at one end of the first extrusion heating tube 4, and a transmission belt 22 is installed between the second pulley 21 and the first pulley 20. Rubber wheels 23 are symmetrically fixedly installed at both ends of the first extrusion heating tube 4 and the second extrusion heating tube 5, and the rubber wheels 23 at corresponding positions on the first extrusion heating tube 4 and the second extrusion heating tube 5 are arranged in friction contact with each other.

[0028] The guide roller 2 is driven to rotate by the feeding motor 3. At the same time, the transmission of the second pulley 21 and the first pulley 20 by the transmission belt 22 will drive the first extrusion heating tube 4 to rotate synchronously. At the same time, the friction and compression contact between the rubber wheels 23 on the first extrusion heating tube 4 and the second extrusion heating tube 5 will drive the second extrusion heating tube 5 to rotate synchronously in the opposite direction, so that the glass fiber felt web between the first extrusion heating tube 4 and the second extrusion heating tube 5 can be continuously and stably transported.

[0029] like Figures 1 to 6As shown, a second limiting rod 24 is symmetrically fixedly installed at the bottom end of the bracket 1 corresponding to the two end positions of the second extrusion heating tube 5, and a mounting seat 25 is slidably installed between the two second limiting rods 24. The mounting seat 25 is provided with a second limiting hole 26 corresponding to the position of the second limiting rod 24, and the second limiting hole 26 is slidably connected to the second limiting rod 24. An extrusion spring 27 is sleeved on the outer side of the top end of the second limiting rod 24, one end of the extrusion spring 27 is fixedly connected to the top of the second limiting hole 26, and the other end of the extrusion spring 27 is fixedly connected to the bracket 1, and the second extrusion heating tube 5 is rotatably installed between the two mounting seats 25 through a bearing.

[0030] By lifting the second extruded heating tube 5, the mounting seats 25 installed at both ends of the second extruded heating tube 5 are driven to slide up along the second limit rod 24. At this time, the extrusion spring 27 is in a compressed state, and the glass fiber felt net is then passed between the first extruded heating tube 4 and the second extruded heating tube 5. Then, the lifting of the second extruded heating tube 5 is canceled, and the extrusion spring 27 pushes the mounting seat 25 to drive the mounting seat 25 to slide down along the second limit rod 24, which will drive the first extruded heating tube 4 and the second extruded heating tube 5 to extrude the glass fiber felt net, making it convenient to install the glass fiber felt net between the first extruded heating tube 4 and the second extruded heating tube 5.

[0031] like Figures 1 to 6 As shown, an exhaust box 28 is fixedly installed in the middle of the bracket 1, an exhaust hole 29 is opened on one side of the exhaust box 28, and an exhaust pipe 30 is fixedly installed in the middle of the exhaust box 28. The exhaust pipe 30 is connected to the interior of the exhaust box 28, and the exhaust pipe 30 is connected to the air inlet end of the suction fan through a pipeline.

[0032] The suction of the suction pipe 30 by the suction fan will drive the atomized resin liquid in the air that has not been sprayed on the surface of the glass fiber felt mesh to be absorbed into the interior of the suction box 28 through the suction hole 29, and the atomized resin liquid remaining in the air will be absorbed by the suction fan, so that the atomized resin liquid in the air can be absorbed, thereby improving the air cleanliness during the spraying process.

[0033] like Figures 1 to 6 As shown, the air extraction hole 29 is arranged at the injection position of the nozzle 10 .

[0034] Realize effective absorption of the sprayed atomized resin liquid.

[0035] The utility model provides a spraying device for glass fiber mat production, and the specific working principle is as follows:

[0036] When the device is in use, the glass fiber felt net is placed on the top of the guide roller 2, and the second extrusion heating tube 5 is lifted up to drive the mounting seats 25 installed at both ends of the second extrusion heating tube 5 to slide up along the second limit rod 24. At this time, the extrusion spring 27 is in a compressed state, and then the glass fiber felt net is passed between the first extrusion heating tube 4 and the second extrusion heating tube 5, and then the lifting of the second extrusion heating tube 5 is cancelled. The pushing of the mounting seat 25 by the extrusion spring 27 will drive the mounting seat 25 to slide down along the second limit rod 24, and will drive the first extrusion heating tube 4 and the second extrusion heating tube 5 to extrude the glass fiber felt net. In the process of conveying the glass fiber felt net, the guide roller 2 is driven to rotate by the feeding motor 3. At the same time, the transmission of the second pulley 21 and the first pulley 20 by the transmission belt 22 will drive the first extrusion heating tube 4 to rotate synchronously. At the same time, the friction and extrusion contact between the rubber wheels 23 on the first extrusion heating tube 4 and the second extrusion heating tube 5 will drive the second extrusion heating tube 5 to rotate synchronously in the opposite direction, so that the glass fiber felt net between the first extrusion heating tube 4 and the second extrusion heating tube 5 can be continuously and stably conveyed;

[0037] During the transportation of the glass fiber felt, the resin liquid in the pressure tank is passed through the feed pipe 9 into the storage pipe 8 by the electromagnetic pump and sprayed out from the nozzle 10 to spray the surface of the glass fiber felt with the resin liquid. In this process, the spraying position of the nozzle 10 has a certain angle with the surface of the glass fiber felt, and the resin liquid sprayed from the nozzle 10 can be blown obliquely to the inside and surface of the glass fiber felt, and the resin liquid on the surface of the upper part of the glass fiber felt can be obliquely entered into the inside and surface of the lower part of the glass fiber felt, so that the glass fiber felt can be sprayed as a whole.

[0038] When the glass fiber felt is sprayed, the rotating plate 18 is driven to rotate by the moving motor 17, and the guide rod 19 moves in a circle along the central axis of the moving motor 17. The first limiting rods 12 installed at both ends of the storage tube 8 are driven to slide back and forth inside the first limiting hole 13 by the extrusion of the guide rod 19 on the guide groove 15. The spray position of the nozzle 10 can be adjusted at any time, so as to spray the glass fiber felt uniformly.

[0039] When the glass fiber felt is sprayed, the nozzle 10 sprays the resin liquid, which is atomized and sprayed on the surface of the glass fiber felt. At the same time, the suction of the suction pipe 30 by the suction fan will drive the atomized resin liquid in the air that has not been sprayed on the surface of the glass fiber felt to be absorbed into the suction box 28 through the suction hole 29, and the atomized resin liquid remaining in the air is absorbed by the suction fan, so that the atomized resin liquid in the air can be absorbed, thereby improving the air cleanliness during the spraying process.

[0040] After the spraying operation, the glass fiber felt net will be transported between the first extrusion heating tube 4 and the second extrusion heating tube 5, and the hot air produced by the hot air blower will enter the interior of the first extrusion heating tube 4 and the second extrusion heating tube 5 through the air inlet pipe 6 and be discharged from the exhaust hole 7. While the glass fiber felt net sprayed with the resin liquid is extruded by the first extrusion heating tube 4 and the second extrusion heating tube 5, the glass fiber felt net can be preheated to improve the stability of the resin liquid inside the glass fiber felt net, and then pass through the heating and dehumidification device again. The length of the heating and dehumidification device can be shortened, which reduces the space occupied by the glass fiber felt production device and improves the processing efficiency of the glass fiber felt net.
