Description

Technical Field

[0001] This utility model is a glass fiber cloth coating device, belonging to the field of fiber cloth coating. Background Technology

[0002] Fiberglass roving is a plain weave fabric made of untwisted rovings, and it is an important base material for hand lay-up fiberglass. The strength of the roving is mainly in the warp and weft directions. For applications requiring high strength in either the warp or weft, it can also be woven into a unidirectional fabric, which can have more untwisted rovings in either the warp or weft. During the manufacturing process of unidirectional fabric, the fiberglass cloth usually needs to be coated to ensure its corrosion resistance.

[0003] In a glass fiber cloth coating device with patent number CN202323300685.5, the patent describes that the dust attached to the upper and lower surfaces of the glass fiber cloth is cleaned by setting a cleaning mechanism, that is, setting a cleaning brush, so as to avoid the dust affecting the coating effect of the glass fiber cloth.

[0004] However, during the dust cleaning process described in the above patent, some fine dust particles come into contact with the cleaning brush. Due to the reduced mass of the dust particles, they are easily suspended in the working air, causing pollution to the surrounding working environment and secondary pollution to the fabric. Therefore, this utility model proposes a glass fiber cloth coating device that can absorb and clean. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A fiberglass cloth coating device includes a working box with an inlet window and an outlet window. A flattening roller and a coating roller are installed inside the working box, with the flattening roller near the inlet window and the coating roller near the outlet window. A flat plate is fixed inside the working box below the flattening roller. A coating assembly is installed on the working box. An electric push rod is fixed on the outer wall of the working box, with an upper cleaning brush connected to its bottom end. A lower cleaning brush, located on the same side as the inlet window, is also fixed on the outer wall of the working box. A suction hood is fixed at the top of the outer wall of the working box, containing a negative pressure fan. The suction hood has a suction pipe and a dust discharge pipe. The suction pipe connects to a suction frame, which is hollow inside. Suction heads are evenly arranged on the inner side of the suction frame, facing the inlet window. A collection assembly is also installed at the top of the outer wall of the working box, with the dust discharge pipe connected to the collection assembly.

[0007] Furthermore, both the upper and lower cleaning brushes include a fixing plate and a cleaning plate, with cleaning brushes on the cleaning plate.

[0008] Furthermore, the coating assembly includes a container, with a discharge pipe extending into the working chamber at the bottom of the container. The discharge pipe has a valve, and a spray pipe is connected to the bottom of the discharge pipe. Spray heads are evenly distributed at the bottom of the spray pipe.

[0009] Furthermore, a material pump is fixedly installed at the top of the working box. The material pump has a material pumping pipe and a connecting pipe. The material pumping pipe is located inside the working box and passes through the flat plate. A collection frame is set at the bottom of the flat plate, and the material pumping pipe is located at the bottom of the collection frame.

[0010] Furthermore, an overflow window is provided through the flat surface, and mounting ears are fixed on the collection frame. The mounting ears are fixed to the bottom of the flat surface with screws, and a door is fixed on one side of the outer wall of the work box.

[0011] Furthermore, the middle part of the dust exhaust pipe is a flexible hose, and the collection assembly includes a collection box. The top of the collection box is fixed with a cover plate with screws. The tail of the dust exhaust pipe passes through the cover plate and is inserted into the collection box. The collection box stores dust-reducing water, and the cover plate has multiple ventilation holes.

[0012] Furthermore, two drive motors are installed on the outer wall of the working box. The output end of the drive motor goes into the inside of the working box and is connected to the corresponding flattening roller and coating roller. The other end of the flattening roller and coating roller goes out of the working box and is connected to a bearing. The bearing is fixed on the outer wall of the working box.

[0013] Furthermore, a heating frame is fixedly installed on the top of the outer wall of the work box, a dust extraction fan is fixedly installed inside the heating frame, a heating element located on one side of the dust extraction fan is fixedly installed inside the heating frame, a heat outlet pipe is also installed on the heating frame, the other end of the heat outlet pipe is connected to the heat outlet frame, the inside of the heat outlet frame is hollow, and heat outlet heads are evenly arranged on the inner side of the heat outlet frame, and a dustproof net is installed on the inner side of the air inlet port of the heating frame.

[0014] The beneficial effects of this utility model are: Pass one end of the fiberglass cloth through the feed window and discharge it from the discharge window. Turn on the electric push rod to drive the upper cleaning brush to descend. Adjust the distance between the upper and lower cleaning brushes to ensure that the fiberglass cloth effectively cleans the dust.

[0015] During the dust cleaning process, the negative pressure fan inside the suction hood is turned on.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a fiberglass cloth coating device, including a working box 1 with a feeding window 2 and a discharging window 3. A flattening roller 4 and a coating roller 5 are installed inside the working box 1. The flattening roller 4 is near the feeding window 2, and the coating roller 5 is near the discharging window 3. A flat plate 6 is fixedly installed inside the working box 1 below the flattening roller 4. A coating assembly is provided on the working box 1. An electric push rod 7 is fixedly installed on the outer wall of the working box 1, and an upper cleaning brush 8 is connected to the bottom end of the electric push rod 7. A cleaning brush 8 is also fixedly installed on the outer wall of the working box 1. A lower cleaning brush 9 is fixedly located on the same side as the feed window 2. A suction hood 10 is fixedly installed at the top of the outer wall of the working box 1. A negative pressure fan 11 is installed inside the suction hood 10. The suction hood 10 has a dust suction pipe 12 and a dust discharge pipe 13. The dust suction pipe 12 is connected to the dust suction frame 14. The dust suction frame 14 is hollow inside, and dust suction heads 15 are evenly arranged on the inner side of the dust suction frame 14. The dust suction heads 15 are arranged facing the feed window 2. A collection component is also installed at the top of the outer wall of the working box 1, and the dust discharge pipe 13 is connected to the collection component.

[0023] See Figure 2 Both the upper cleaning brush 8 and the lower cleaning brush 9 include a fixing plate 16 and a cleaning plate 17. The cleaning plate 17 has a cleaning brush. Both the upper cleaning brush 8 and the lower cleaning brush 9 are divided into a fixing plate 16 and a cleaning plate 17. It should be noted that the fixing plate 16 and the corresponding cleaning plate 17 are fixed together with screws to ensure that the corresponding cleaning plate 17 can be disassembled and replaced later. The bottom end of the electric push rod 7 is specifically fixedly connected to the fixing plate 16 of the upper cleaning brush 8, while the fixing plate 16 of the lower cleaning brush 9 is fixedly integrated on the outer wall of the work box 1.

[0024] See Figure 1The coating assembly includes a container 18, with a discharge pipe extending into the working chamber 1 at its bottom. The discharge pipe has a valve and a spray pipe 19 connected to its bottom. Spray nozzles are evenly distributed at the bottom of the spray pipe 19. A suction pump 20 is fixedly mounted on the top of the working chamber 1. The suction pump 20 has a suction pipe 21 and a connecting pipe. The suction pipe 21 is located inside the working chamber 1 and penetrates a flat plate 6. A collecting frame 22 is located at the bottom of the flat plate 6, and the suction pipe 21 is located inside the bottom of the collecting frame 22. The plate 6 has an overflow window 23 that runs through it. A mounting ear plate 24 is fixed to the bottom of the plate 6 with screws on the collection frame 22. A door 25 is fixed to one side of the outer wall of the work box 1. The collection frame 22 is detachable, and its interior is cleaned periodically. The container 18 serves as a paint storage container, providing a continuous material source for the entire coating operation, avoiding frequent paint additions that could cause work interruptions, and ensuring continuous production. The discharge pipe is connected to a spray pipe 19. The uniformly arranged spray heads at the bottom of the plate 6 can spray the coating evenly onto the surface of the fiberglass cloth in a surface manner, rather than dripping from a single point. This ensures that the coating is initially evenly distributed before contacting the coating roller 5, reducing the workload of the coating roller and further improving the uniformity of the final coating. The collection frame 22 at the bottom of the plate 6 can collect excess coating that overflows from the surface of the plate 6 or drips from the fiberglass cloth, preventing the coating from directly scattering to the bottom of the working box 1 and causing accumulation and pollution. This provides a centralized material collection space for subsequent recycling. The pump 20, through the suction pipe 21 that penetrates the plate 6 and extends to the bottom of the collection frame 22, can pump the collected excess coating back into the holding box for reuse. The overflow window 23 that runs through the surface of the plate 6 can quickly guide excess coating that does not flow into the collection frame 22 in time into the collection frame, preventing the coating from accumulating and overflowing on the plate, further ensuring the integrity of the recycling system. The door 25 on one side of the outer wall of the working box 1 facilitates the disassembly of the collection frame 22.

[0025] See Figure 1 , Figure 4 and Figure 5The dust exhaust pipe 13 has a flexible hose in the middle. The collection assembly includes a collection box 26. A cover plate is fixed to the top of the collection box 26 with screws. The tail of the dust exhaust pipe 13 passes through the cover plate and is inserted into the collection box 26. The collection box 26 stores dust-reducing water. Multiple ventilation holes are provided on the cover plate. Two drive motors 27 are installed on the outer wall of the working box 1. The output end of the drive motor 27 passes into the working box 1 and is connected to the corresponding flattening roller 4 and coating roller 5. The other end of the flattening roller 4 and coating roller 5 passes out of the working box 1 and is connected to a bearing 28. 28 is fixed to the outer wall of the working box 1. A heating frame 29 is fixed to the top of the outer wall of the working box 1. A dust collector is fixed inside the heating frame 29. A heating element 30 located on one side of the dust collector is fixed inside the heating frame 29. A heat outlet pipe 31 is also provided on the heating frame 29. The other end of the heat outlet pipe 31 is connected to a heat outlet frame 32. The heat outlet frame 32 is hollow inside, and heat outlet heads are evenly arranged on the inner side of the heat outlet frame 32. A dustproof net 33 is provided inside the air inlet of the heating frame 29. The dust-reducing water source is stored inside the collection box 26. This allows the dust-laden airflow introduced by the dust exhaust pipe 13 to directly contact and merge with the water. Therefore, the adsorbed dust particles are absorbed and settled by the water, effectively collecting the dust, reducing the dust concentration in the working environment, and protecting the health of operators. Multiple vents on the cover allow clean airflow to be discharged from the collection box 26 after the dust settles, preventing excessive air pressure inside the box from hindering dust removal. The screw-fixed cover of the collection box facilitates regular cleaning of the settled dust. The collection box 26 can be installed in a conventional manner, that is, it can be fixed to the outer wall of the work box 1 with screws. At the top, the collection box 26 can be disassembled to process the dust collected inside. Two independent drive motors 27 are connected to the flattening roller 4 and the coating roller 5 respectively to achieve the flattening and coating of the fabric. The bearing setting can reduce the frictional resistance when the roller rotates. The heating element 30 in the heating frame 29 heats the air inside the heating frame 29. The hot air is sent to the surface of the fiberglass cloth by the dust suction fan to heat and dry it, so as to improve the processing effect. The dustproof net 33 on the inside of the air inlet of the heating frame 29 can filter the dust in the outside air entering the heating system.

[0026] During use, one end of the fiberglass cloth is passed through the feed window 2 and discharged from the discharge window 3. The electric push rod 7 is turned on, causing the upper cleaning brush 8 to descend. Therefore, the distance between the upper cleaning brush 8 and the lower cleaning brush 9 is adjusted to ensure effective dust removal from the fiberglass cloth. During the dust removal process, the negative pressure fan 11 inside the suction hood 10 is turned on. The negative pressure fan 11 adsorbs the dust generated during cleaning through the suction head 15 of the dust suction frame 14, and then guides it into the collection component through the dust discharge pipe 13 for centralized dust treatment. This protects the working environment and avoids secondary contamination of the cloth. The flattening roller 4 is close to the feed port to pre-treat the fiberglass cloth, smoothing out wrinkles to improve the uniformity of subsequent coating. The coating roller 5 is close to the discharge port and undertakes the core coating operation to ensure the coating adhesion effect. The flat plate 6 below the flattening roller 4 provides support for the flattening operation. The support surface ensures that the force of the flattening roller is evenly transmitted to the fabric, preventing flattening failure due to lack of support. The coating component is used to store and transport the coating, providing material support for the coating roller operation. Therefore, this utility model has the function of effectively cleaning dust from the surface of the fiberglass cloth. After pretreatment by the flattening roller, the coating is finally completed by the coating roller. The components are compactly arranged and complementary in function, which not only ensures the coating quality but also improves the cleanliness and continuity of the operation. The connection between the suction pipe 12 and the suction frame 14 is installed using a flange, ensuring the communication between the inside of the suction pipe 12 and the inside of the suction frame 14. The suction frame 14 can be disassembled later, making it convenient to replace. The other end of the heat outlet pipe 31 is connected to the heat outlet frame 32, which is also connected by a flange. The heat outlet frame 32 can also be disassembled and is designed to be detachable.

[0027] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
