Description

Technical Field

[0001] The utility model relates to the field of glass fiber cloth preparation, in particular to a coating device for glass fiber cloth preparation. Background Art

[0002] Fiberglass woven fabric is a plain weave fabric with untwisted rovings and is an important base material for hand-laid fiberglass reinforced plastics. The strength of woven fabric lies primarily in the warp and weft directions. For applications requiring high strength in either the warp or weft direction, woven fabric can also be made into a unidirectional fabric, which can have more untwisted rovings arranged in either direction, resulting in a single warp or single weft fabric.

[0003] A search of the patent document with publication number CN211897385U discloses "a glass fiber cloth coating device, wherein the glass fiber cloth coating device of this device uses the bristles on the brush roller to pick up the coating liquid to coat the glass fiber cloth passing through the coating area. As the brush roller rotates, the bristles on the two brush rollers respectively contact the two sides of the glass fiber cloth, so that the coating liquid carried by the bristles on the brush rollers is squeezed and penetrates into the glass fiber cloth, and a coating layer is formed on the surface of the glass fiber cloth, thereby improving the coating effect of the glass fiber cloth. The scraper assembly can scrape the coating layer on the glass fiber cloth flat, so that the coating layer on the glass fiber cloth has a certain smoothness, and can control the thickness of the coating layer on the surface of the glass fiber cloth. At the same time, the coating liquid scraped off by the scraper assembly will fall back into the accommodating chamber, thereby improving the utilization rate of the coating liquid."

[0004] When the above device is in operation, since the above device needs to pass the glass fiber cloth through the window, a certain distance needs to be left at the window for the glass fiber cloth to pass through. As a result, when the above device coats the glass fiber cloth through the brush roller, excessive coating liquid adhered to the outer ring of the brush roller is easy to flow out of the device through the window, thereby resulting in waste of coating liquid.

A fixing frame 31 is provided between the corresponding two transverse sliding blocks 3, and the fixing frame 31 is fixed to the liquid storage tank 2. Both ends of the fixing frame 31 are fixed with a first spring 32, and the other end of the first spring 32 is fixed to the corresponding transverse sliding block 3. A coating roller 33 is rotatably connected between the two corresponding transverse sliding blocks 3 at the front and rear. The corresponding ends of the two coating rollers 33 are fitted together, and the lower end of the coating roller 33 is lower than the upper end of the cloth-discharging square ring frame 21. Two fixed plates 34 are fixed to the bottom of the plate surface of the pad frame 1, and a first guide roller 35 is rotatably connected between the two fixed plates 34. The pad frame 1 is opened at the position corresponding to the cloth-discharging square ring frame 21. There is a through groove, and one end of the first guide roller 35 is located in the middle position of the through groove of the cloth-discharging square ring frame 21 and the pad frame 1. A fixed rod 36 is provided above the two coating rollers 33, and the fixed rod 36 is fixed to the inner wall of the liquid storage tank 2, and the outer periphery of the fixed rod 36 is rotatably connected to the second guide roller 37; through the sliding connection between the transverse slider 3 and the liquid storage tank 2 and the elasticity of the first spring 32, the two coating rollers 33 can be pushed apart during operation, so that the glass fiber cloth can pass between the two coating rollers 33, and when the two coating rollers 33 are not under force, the two coating rollers 33 can clamp the glass fiber cloth, so that when the glass fiber cloth is conveyed, it can drive the two coating rollers 33 to roll, thereby coating the glass fiber cloth.

[0030] The recovery mechanism includes a liquid collecting frame 4, which is fixed to the lower end of the pad raising frame 1, and the position of the liquid collecting frame 4 corresponds to the position of the cloth discharging square ring frame 21. A liquid guide plate 41 is fixed to the inner wall of the liquid collecting frame 4, and a pump 42 is installed at one end of the liquid collecting frame 4. The liquid guide plate 41 is inclined at 45 degrees, and the water inlet of the pump 42 is located at the bottom of the liquid collecting frame 4. A connecting pipe 43 is fixed to the output end of the pump 42, and the output end of the connecting pipe 43 extends into the liquid storage tank 2. An inclined frame 44 is fixed to the upper end of the liquid storage tank 2. The inclined frame 44 is inclined at 15 degrees, and a groove is provided at the lower end of the inclined frame 44. The inner walls of both ends of the inclined frame 44 are slidably connected with a longitudinal slider 45. The lower end of the longitudinal slider 45 is fixed with a second spring 46, and the lower end of the second spring 46 is fixed to the upper end surface of the inclined frame 44. It is rotatably connected to a squeezing roller 47; through the setting of the liquid collecting frame 4, the coating liquid leaked through the cloth outlet square ring frame 21 when the device is in operation can be recovered and processed, and through the inclined setting of the liquid guide plate 41 and the water inlet of the pump 42 being located at the bottom of the liquid collecting frame 4, even if a small amount of coating liquid is collected inside the liquid collecting frame 4, the water inlet of the pump 42 can be submerged, so that when the pump 42 is started, the coating liquid in the liquid collecting frame 4 can be drawn back into the liquid storage tank 2 to the maximum extent. After the glass fiber cloth is coated, it is rolled on it by the squeezing roller 47, so that the excess coating liquid on the outer layer of the glass fiber cloth can be rolled out, and then through the inclined setting of the inclined frame 44, the rolled out coating liquid can flow along the inclined frame 44 into the liquid storage tank 2 for recovery. In this way, the waste and loss of coating liquid can be minimized during operation of the device.

[0031] Working principle: When the device is in operation, first fill the liquid storage tank 2 with coating liquid so that the water level of the coating liquid is lower than the uppermost end of the cloth-discharging square ring frame 21, and the coating liquid can cover the bottom of the coating roller 33. Through the sliding connection between the transverse slider 3 and the liquid storage tank 2 and the elasticity of the first spring 32, the two coating rollers 33 can be pushed apart during operation, so that the glass fiber cloth can pass between the two coating rollers 33. When the two coating rollers 33 are not under force, the two coating rollers 33 can clamp the glass fiber cloth. In this way, when the glass fiber cloth is being transported, the two coating rollers 33 can be driven to roll, thereby coating the glass fiber cloth. The setting of the liquid collecting frame 4 can pass through the cloth-discharging square ring when the device is in operation. The coating liquid leaked from the frame 21 is recovered and processed, and through the inclined setting of the liquid guide plate 41 and the water inlet of the pump 42 being located at the bottom of the liquid collecting frame 4, even if a small amount of coating liquid is collected inside the liquid collecting frame 4, the water inlet of the pump 42 can be submerged, so that when the pump 42 is started, the coating liquid in the liquid collecting frame 4 can be pumped back into the liquid storage tank 2 to the maximum extent. After the glass fiber cloth is coated, the squeezing roller 47 rolls it out to roll out the excess coating liquid on the outer layer of the glass fiber cloth, and then through the inclined setting of the inclined frame 44, the rolled-out coating liquid can flow along the inclined frame 44 into the liquid storage tank 2 for recovery. In this way, the device can minimize the waste and loss of coating liquid during operation.
