Description

Technical Field

[0001] This utility model relates to the field of fabric coating technology, and in particular to a fabric coating device. Background Technology

[0002] In the textile industry, fabric coating is one of the key processes for improving fabric performance. By coating the fabric surface with specific materials, multiple functions such as waterproofing, stain resistance, antibacterial properties, and flame retardancy can be imparted to the fabric, making it widely used in outdoor clothing, sports equipment, automotive interiors, medical protective equipment, and many other fields. As the market's demand for fabric functionality continues to increase, and as requirements for product quality and production efficiency become increasingly stringent, higher standards are being set for the performance of fabric coating equipment.

[0003] In the prior art, traditional fabric coating devices have significant drawbacks in use. For example, traditional coating devices often use a nozzle to spray the coating onto the fabric surface and then use a scraper to smooth it. However, most traditional scrapers are straight strips, and there is a certain gap between the nozzles. When smoothing, uneven coating is likely to occur, affecting the coating effect. Therefore, this utility model proposes a fabric coating device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device for fabrics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fabric coating device includes a base, four rectangularly arranged vertical plates fixedly connected to the upper end of the base, a material roller rotatably connected between two of the vertical plates on the same side, and a take-up roller rotatably connected between the other two vertical plates. A fixing frame is fixedly connected to the upper end of the base, and a smoothing mechanism for smoothing the coating is provided between the inner walls of the two ends of the fixing frame. The smoothing mechanism includes a scraper fixedly connected between the inner walls of the two ends of the fixing frame. The scraper has a "V" shape design, and the lower end of the scraper contacts the upper end of the fabric. A limiting mechanism for limiting the fabric is provided inside the fixing frame.

[0007] Preferably, the limiting mechanism includes two limiting rollers rotatably connected between the inner walls of both ends of the fixed frame, and the two limiting rollers are arranged symmetrically.

[0008] Preferably, the fixing frame has an internal cavity, and multiple nozzles communicating with it are installed on the inner top of the fixing frame, with the multiple nozzles arranged at equal intervals.

[0009] Preferably, a pump body is installed on the side wall of the fixed frame, the pump body is connected to the cavity through a discharge pipe, and a feed pipe is provided at the lower end of the pump body.

[0010] Preferably, a collection box is provided at the upper end of the base.

[0011] Preferably, the collection box is located directly below the mounting bracket.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a smoothing mechanism, the scraper adopts a "V" shape design. When the fabric passes through the scraper, the coating it carries passes through the scraper, and the scraper can smooth the coating. At the same time, because the scraper is "V" shaped, it can push the coating on the upper part of the fabric to both ends, so that the coating can be evenly applied to the surface of the fabric and improve the uniformity of coating.

[0014] 2. By setting up a collection box, the scraper can push the paint to both sides of the fabric. Excess paint will fall over the edge of the fabric and enter the collection box, thus collecting the excess paint, avoiding paint waste, and improving the practicality of the device.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1-6 A coating device for fabric includes a base 1. Four rectangular vertical plates 2 are fixedly connected to the upper end of the base 1. A material roller 3 is rotatably connected between two of the vertical plates 2 on the same side, and a take-up roller 7 is rotatably connected between the other two vertical plates 2. A fixing frame 4 is fixedly connected to the upper end of the base 1. A scraping mechanism for scraping the coating is provided between the inner walls of the two ends of the fixing frame 4. The scraping mechanism includes a scraper 11 fixedly connected between the inner walls of the two ends of the fixing frame 4. The scraper 11 is designed in a "V" shape, and the lower end of the scraper 11 contacts the upper end of the fabric.

[0024] Specifically, the fixed frame 4 is provided with a limiting mechanism for limiting the fabric. The limiting mechanism includes two limiting rollers 9 rotatably connected between the inner walls of both ends of the fixed frame 4. The two limiting rollers 9 are arranged symmetrically.

[0025] Specifically, the fixed frame 4 has a cavity 13 inside, and multiple nozzles 10 connected to it are installed on the top of the fixed frame 4. The multiple nozzles 10 are arranged at equal intervals. A pump body 12 is installed on the side wall of the fixed frame 4. The pump body 12 is connected to the cavity 13 through a discharge pipe 5. A feed pipe 6 is provided at the lower end of the pump body 12.

[0026] Specifically, a collection box 8 is provided at the upper end of the base 1. The collection box 8 is located directly below the fixing frame 4. Since the scraper 11 is designed in a "V" shape, it can push the paint on the upper end of the fabric to both ends, so that the paint can be evenly coated on the surface of the fabric and improve the uniformity of coating. The scraper 11 can push the paint to both sides of the fabric. Excess paint will fall through the edge of the fabric and enter the collection box 8, so as to collect the excess paint.

[0027] In use, one end of the fabric on the material roller 3 is pulled out and passed through the lower ends of the two limiting rollers 9 and the lower end of the scraper 11. Then, the pulled-out end of the fabric is fixed to the take-up roller 7. The take-up roller 7 is rotated by the winding machine to take up the fabric. At the same time, the pump body 12 is driven. The pump body 12 draws the paint in through the feed pipe 6 and pumps it into the cavity 13 through the discharge pipe 5. Then, it is sprayed onto the surface of the fabric by the nozzle 10. When the fabric passes through the scraper 11, the scraper 11 can smooth the paint due to its "V" shape design. At the same time, the scraper 11 can push the paint on the upper end of the fabric to both ends due to its "V" shape design, so that the paint can be evenly coated on the surface of the fabric, improving the uniformity of coating. The scraper 11 can push the paint to both sides of the fabric. Excess paint will fall through the edge of the fabric and enter the collection box 8 to collect the excess paint and avoid paint waste.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
