Description

Technical Field

[0001] The utility model relates to a fabric coating device, in particular to a sun-proof and anti-ultraviolet fabric spraying device. Background Art

[0002] Fabrics can achieve UV protection through a variety of processes, such as the addition of functional sunscreen additives. By adding special sunscreen additives to fabrics, the fabric itself has the ability to reflect or absorb UV rays, thereby reducing damage to the skin. These additives are usually tightly bonded to the fabric fibers and are not easily shed, providing long-lasting sun protection. Functional sunscreen fabrics also have good breathability and moisture absorption, making them comfortable to wear. Another example is sunscreen coating, which coats the surface of the fabric with a special material that effectively reflects and scatters UV rays, thereby reducing direct contact with the skin. The most common is silver-coated fabric, which not only provides excellent UV protection but is also relatively affordable.

[0003] Fabrics that achieve sun protection and UV resistance through the addition of coatings undergo a coating process. Coating can be performed by spraying or roller coating. Compared to spraying, roller coating offers advantages such as high coating efficiency, controllable film thickness, and minimal pollution. However, roller coating is prone to uneven coating, especially when the coating concentration or viscosity fluctuates, which can easily lead to coating quality issues. Summary of the Invention

[0004] The utility model provides a sun-proof and anti-ultraviolet fabric spraying device, which solves the problem of uneven glue discharge in roller coating in the prior art.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a sun-proof and anti-ultraviolet fabric spraying equipment, including a feeding box, a coating roller and a carrying roller, the coating roller and the carrying roller are in abutment with each other, the feeding box is composed of a front template and a rear template, two side plates are sealed and fixed on both sides of the front template and the rear template, a liquid storage tank is formed in the feeding box, a feeding roller is horizontally rotatably connected between the two side plates, the feeding roller is partially exposed in the liquid storage tank, a first input arc groove with equal spacing is formed between the front template and the feeding roller, and a first input arc groove with equal spacing is formed between the rear template and the feeding roller. The width of the first input arc groove is greater than the width of the first output arc groove; the coating roller is also horizontally rotated and connected between the two side plates, the upper part of the coating roller is embedded in the bottom of the feed box, and the lower part is exposed. The first output arc grooves with equal spacing are formed between the front template and the coating roller, and the second input arc grooves with equal spacing are formed between the rear template and the coating roller. A connecting groove is connected between the first input arc groove and the second output arc groove; a power component for driving the coating roller and the feed roller to rotate is provided on the side plate, and the linear speed of the feed roller is required to be higher than the linear speed of the coating roller.

[0006] The liquid storage tank in the present invention is used to store paint. When the feed roller begins to rotate, the adhesion between the paint and the surface of the feed roller continuously drives the paint into the first input circular arc groove. Since the surface finish of the feed roller is basically consistent and the linear speed is consistent at all locations, the traction effect on the paint tends to be consistent, ultimately making the paint flow speed at all locations in the first input circular arc groove tend to be consistent. Since the gap of the first output circular arc groove is smaller, most of the paint in the first input circular arc groove flows downward along the connecting groove. The rotating coating roller drives the paint to flow into the second output circular arc groove, and finally adheres to the surface of the coating roller to participate in the coating of the fabric. The linear speed of the feed roller is required to be higher than that of the coating roller. The purpose is to ensure that the paint supply speed of the connecting groove is greater than the consumption speed, so that the connecting groove is in a positive pressure state. This helps to ensure that the coating thickness on the coating roller is uniform and continuous.

[0007] Furthermore, a valve stem is provided between the two side plates for horizontal rotation. The valve stem body is cylindrical with a through opening formed in the middle. The valve stem extends through the connecting groove. By rotating the valve stem, the orientation of the opening can be switched. When the opening is oriented vertically, the upper and lower sides of the connecting groove are connected. When the opening is oriented horizontally, the upper and lower sides of the connecting groove are disconnected.

[0008] Furthermore, the top cover of the feed box is provided with a cover body, and the cover body is provided with a feeding pipe and a liquid level sensor. When the liquid level sensor detects that the liquid level of the paint has reached a low level, the paint can be injected through the feeding pipe. When the liquid level sensor detects that the liquid level of the paint has reached a high level, the feeding pipe stops injecting the paint. In this way, the utility model has the function of autonomous feeding.

[0009] Furthermore, the spacing of the second input arcuate grooves is not less than the spacing of the second output arcuate grooves, and the spacing of the second output arcuate grooves is 0.2 to 0.5 mm. After coating, the coating thickness on the coating roller is significantly thinner. Therefore, the spacing within the second input arcuate grooves is significantly greater than the residual coating thickness on the coating roller, which effectively prevents coating accumulation at the ends of the second input arcuate grooves.

[0010] Therefore, compared with the prior art, the present invention has the following characteristics: 1. As the feed roller rotates, the surface adhesion effect between the paint and the feed roller will continuously drive the paint to flow into the first input circular arc groove, so that the paint flow speed at various locations in the first input circular arc groove tends to be consistent. The linear speed requirement of the feed roller is higher than the linear speed of the coating roller. The purpose is to ensure that the paint supply speed of the connecting groove is greater than the consumption speed, so that the connecting groove is in a positive pressure state, and ultimately the coating thickness on the coating roller is uniform and continuous, and the fluidity requirement for the paint itself is relatively low.

[0014] The technical solution of the present invention will be further specifically described below with reference to the embodiments and the accompanying drawings.

[0016] Example 1: See Figure 1 A sunscreen and anti-ultraviolet fabric spraying equipment includes a feed box 10, a coating roller 20 and a carrying roller 30. The coating roller and the carrying roller are both rubber rollers and are abutted up and down. The feed box is composed of a front template 40 and a rear template 50. The front template and the rear template are sealed and fixed with two side plates 60 on both sides. A liquid storage tank 70 is formed in the feed box. A feed roller 80 is horizontally connected between the two side plates. The feed roller is partially exposed in the liquid storage tank. A first input arc groove 81 with equal spacing is formed between the front template and the feed roller. A first output arc groove 82 with equal spacing is formed between the rear template and the feed roller. The first input arc groove The width is 1 to 1.5 mm, and the width of the first output arc groove is 0.2 to 0.5 mm; the coating roller is also horizontally rotated and connected between the two side plates, the upper part of the coating roller is embedded in the bottom of the feed box, and the lower part is exposed. A second output arc groove 21 with equal spacing is formed between the front template and the coating roller, and a second input arc groove 22 with equal spacing is formed between the rear template and the coating roller. A connecting groove 11 is connected between the first input arc groove and the second output arc groove; a power component for driving the coating roller and the feed roller to rotate is provided on the side plate, and the linear speed of the feed roller is required to be higher than the linear speed of the coating roller.

[0017] The reservoir in this embodiment is used to store the paint. When the feed roller begins to rotate, the adhesion between the paint and the surface of the feed roller continuously drives the paint into the first input circular groove. Since the surface finish of the feed roller is essentially uniform and the linear speed is consistent at all locations, the traction effect on the paint tends to be consistent, ultimately making the paint flow rate at all locations within the first input circular groove tend to be consistent. Since the gap between the first output circular groove is smaller, most of the paint in the first input circular groove flows downward along the connecting groove. The rotating coating roller drives the paint to flow into the second output circular groove, where it eventually adheres to the surface of the coating roller and participates in the coating of the fabric. The linear speed of the feed roller is required to be higher than that of the coating roller. This is to ensure that the paint supply rate of the connecting groove is greater than the paint consumption rate, thereby maintaining a positive pressure state within the connecting groove. This helps to ensure a uniform and continuous coating thickness on the coating roller.

[0018] See Figure 1 A valve stem 90 is installed horizontally between the two side plates. The main body of the valve stem is cylindrical, with a through opening 91 formed in the middle. The valve stem is a connecting groove. By rotating the valve stem, the direction of the opening can be switched. When the opening is vertical, the upper and lower sides of the connecting groove are connected. When the opening is horizontal, the upper and lower sides of the connecting groove are disconnected.

[0019] See Figure 2The side plate is rotatably connected to a cylinder 92, and a shift rod 93 is fixed to the outer end of the valve stem. The shift rod is rotatably connected to the cylinder rod of the cylinder. A first limit rod 94 and a second limit rod 95 are also fixed to the side plate; when the shift rod is pushed by the cylinder to abut against the second limit rod, the valve stem is in a normally open state, and when the shift rod is pulled by the cylinder to abut against the first limit rod, the valve stem is in a normally closed state.

[0020] See Figure 2 and Figure 3 The power assembly includes a reduction motor 61 fixed to the side panel, a multi-stage synchronous pulley 62 coaxially connected to the feed roller, a synchronous pulley 63 coaxially connected to the coating roller, and a synchronous belt 64. By switching the connection position of the synchronous belt and the multi-stage synchronous pulley, the speed ratio between the feed roller and the coating roller can be adjusted to meet different coating requirements.

[0021] See Figure 1 The top cover of the feed box is provided with a cover body 12, on which a feeding pipe 13 and a liquid level sensor 14 are provided. When the liquid level sensor detects that the liquid level of the paint has reached a low level, the paint can be injected through the feeding pipe. When the liquid level sensor detects that the liquid level of the paint has reached a high level, the feeding pipe stops injecting the paint. In this way, this embodiment has the function of autonomous feeding.

[0022] Furthermore, the spacing of the second input arcuate grooves is no less than the spacing of the second output arcuate grooves, and the spacing of the second output arcuate grooves is 0.2 to 0.5 mm. After coating, the coating thickness on the coating roller is significantly thinner. Therefore, the spacing within the second input arcuate grooves is significantly greater than the residual coating thickness on the coating roller, which effectively prevents coating accumulation at the ends of the second input arcuate grooves.

[0023] See Figure 1 A first clamping plate 51 is fixed on the rear template, a second clamping plate 52 is bolted to the first clamping plate, and at least two clamping holes 53 are formed between the two clamping plates.

[0024] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
