[0002] Fiberglass cloth is an inorganic non-metallic material with good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. In order to enhance the wear resistance of fiberglass cloth, the existing technology usually sprays a wear-resistant coating onto the surface of the fiberglass cloth, thereby avoiding severe wear and tear that could lead to cracking of the fiberglass cloth during use.

[0003] Chinese Patent No. CN220991431U discloses a surface coating device for fiberglass fabric, relating to the field of fiberglass fabric processing technology. This invention utilizes the combined action of a roll clamping block, a clamping block shaft, a first gear, a turntable, an outer toothed groove, an annular slide rail, a rotating ring, a second motor, and the second gear and inner toothed groove. The rotation of the roll clamping block is controlled by the second motor, facilitating rapid clamping of the fiberglass fabric roll and improving feeding efficiency, thereby increasing the efficiency of fiberglass fabric coating.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In order to improve the wear resistance of fiberglass cloth, it is necessary to spray wear-resistant coating on both sides. The above-mentioned spraying device can only spray coating on one side of the fiberglass cloth roll at a time. When the other side of the fiberglass cloth roll needs to be sprayed, the fiberglass cloth roll needs to be removed and readjusted, which reduces the spraying efficiency. Utility Model Content

Detailed Implementation

[0020] Example 1

[0021] like Figures 1 to 4 As shown, this utility model proposes an electronic-grade fiberglass cloth spraying device, including a base 1, tension rollers 3, flattening rollers 4, a spraying mechanism, and a drying mechanism. A spraying box 101 is located in the middle of the base 1, with baffles at both ends to prevent paint from leaking out and causing contamination during spraying. A winding mechanism 2 is located at both the left and right ends of the base 1. Two sets of tension rollers 3 are symmetrically installed inside the spraying box 101 at both ends. Two sets of flattening rollers 4 are symmetrically distributed inside the spraying box 101 and positioned above the two sets of tension rollers 3. The flattening roller 4 is driven to rotate by a motor installed on the spray box 101; the spraying mechanism consists of a feed pipe 5 installed on the inner wall of the spray box 101, a multi-component diversion pipe 501 installed at the output end of the feed pipe 5, and a multi-component nozzle 502 installed on the diversion pipe 501. The multi-component diversion pipe 501 is symmetrically distributed vertically; the drying mechanism is located at the output end of the spraying mechanism. The drying mechanism consists of an air inlet pipe 6 installed on the inner wall of the spray box 101 and two sets of uniform air boxes 601 installed at the output end of the air inlet pipe 6. The two sets of uniform air boxes 601 are symmetrically arranged, and each set of air outlets 603 is provided at one opposite end of the two sets of uniform air boxes 601.

[0022] Furthermore, the winding mechanism 2 consists of two sets of oppositely arranged conical platforms 201. The two sets of conical platforms 201 are respectively inserted into both ends of the roller wound with fiberglass cloth. One set of conical platforms 201 is rotatably connected to the base 1, while the other set of conical platforms 201 is driven by a drive mechanism to rotate and move horizontally along the base 1. The drive mechanism consists of a first hydraulic rod mounted on the base 1 and a motor mounted on the output end of the first hydraulic rod. The motor is connected to the conical platform 201 for transmission. The first hydraulic rod can drive one set of conical platforms 201 to insert and press the roller wound with fiberglass cloth against the other set of conical platforms 201. The controller starts the motor to drive the conical platforms 201 to rotate, thereby driving the roller to rotate to unload or wind up the fiberglass cloth, making installation convenient and quick.

[0023] Furthermore, two branch pipes 501 are installed at both the upper and lower output ends of the feed pipe 5. The nozzles 502 on the two adjacent branch pipes 501 are spaced apart. The nozzles 502 are fan-shaped nozzles. A solenoid valve is installed at the connection between the nozzles 502 and the branch pipes 501. The spaced nozzles 502 on the two adjacent branch pipes 501 can improve the uniformity of spraying the fiberglass cloth. The fan-shaped nozzles make the paint contact with the fiberglass cloth more uniform and save paint.

[0024] Furthermore, multiple sets of partition plates 602 are evenly installed inside the air distribution box 601. These partition plates 602 divide the inner cavity of the air inlet pipe 6 into multiple air distribution chambers. The air outlet 603 corresponds to the air distribution chamber. Multiple sets of air distribution pipes 604 are arranged between the output end of the air inlet pipe 6 and the air distribution box 601, and the output end of the air distribution pipes 604 is connected to the air distribution chamber. It should be noted that both the feed pipe 5 and the air inlet pipe 6 can be made into flexible hoses. The input ends of both the feed pipe 5 and the air inlet pipe 6 extend to the outside of the spray box 101. The diversion pipe 501 and the air distribution box 601 can be connected to the spray box 101 through a second hydraulic rod. The corresponding second hydraulic rod can drive the two sets of air distribution boxes 601 to move closer or further apart. The corresponding second hydraulic rod can also drive the multiple diversion pipes 501 arranged vertically to move closer or further apart, thereby adjusting the drying and spraying effects. The adjustment is convenient and quick.

[0025] Furthermore, a collection box 503 is slidably connected below the spraying mechanism and on the base 1. The side wall of the spray box 101 is provided with a clearance opening 102 corresponding to the spray box 101. Excess paint can be collected through the collection box 503 to avoid contamination of the base 1, and excess paint can be recycled.

[0026] In this embodiment, a roller wound with fiberglass cloth is installed on the winding mechanism 2 at the input end of the base 1, and an empty set of rollers is installed on the winding mechanism 2 at the output end of the base 1. The end of the fiberglass cloth passes through the bottom of the first set of tension rollers 3, then through the top of the two sets of flattening rollers 4, then through the bottom of the other set of tension rollers 3, and finally connects to the roller at the output end. The fiberglass cloth is fed and wound up by the two sets of winding mechanisms 2. The fiberglass cloth is stretched and flattened by the two sets of tension rollers 3 and the two sets of flattening rollers 4. The fiberglass cloth between the two sets of flattening rollers 4 is located between the upper and lower multi-group flow pipes 501 and between the upper and lower sets of uniform air boxes 601. It is supplied by an external coating mechanism. The coating is fed into the feed pipe 5 by the feed pipe 5. The coating is diverted by the multi-group diversion pipe 501 and sprayed onto both sides of the fiberglass cloth by the multi-group nozzles 502. The width of the spray area can be adjusted according to the width of the fiberglass cloth by the solenoid valve, which can further save coating. The external drying mechanism is connected to the input end of the air inlet pipe 6 to feed the drying air into the air inlet pipe 6. The drying air is then diverted by the multi-group uniform air pipes 604 and enters the corresponding uniform air chambers. Then it is sprayed outward from the air outlet 603. The drying air can be evenly distributed and blown onto both sides of the fiberglass cloth to quickly dry the coating on both sides of the fiberglass cloth. After drying, the fiberglass cloth is wound up by the winding mechanism 2 at the output end.

[0027] Example 2

[0028] like Figure 2 As shown, the electronic-grade fiberglass cloth spraying device proposed in this utility model, compared with the first embodiment, has a tensioning mechanism at the connection between the tensioning roller 3 and the spray box 101. The tensioning mechanism includes a mounting base 301 and a slider 302. Two sets of mounting bases 301 are provided, and the two sets of mounting bases 301 are symmetrically installed on the inner wall of the spray box 101. The elastic element 303 is U-shaped. The slider 302 is slidably connected to the inner wall of the mounting base 301. The two ends of the tensioning roller 3 are connected to the two sets of corresponding sliders 302. The top and bottom ends of the slider 302 are provided with elastic elements 303. The end of the elastic element 303 away from the slider 302 is connected to the mounting base 301. The mounting base 301 is also provided with a fixing rod. The slider 302 and the elastic element 303 are slidably sleeved on the outside of the fixing rod, which improves the sliding stability of the slider 302 relative to the mounting base 301.

[0029] In this embodiment, when the tension of the fiberglass cloth changes, the slider 302 will slide up and down along the inner wall of the elastic element 303 under the elastic force of each set of elastic elements 303, so as to drive the tension roller 3 to adjust adaptively, thereby adjusting the tension of the fiberglass cloth, avoiding the fiberglass cloth being stretched too tight or too loose, and improving the subsequent spraying effect.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
