Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] refer to Figure 1 、 Figure 2 、 Figure 3 The external hot water source enters the preheating box plate 102 from the water inlet pipe. The preheating box plate 102 can contact the bottom of the raw glass fiber cloth product, so that the paint falling on its surface is heated, which plays the role of preheating and accelerating solidification, improving the quality of coating, and preventing the paint from flowing. The guide roller 103 can guide the movement of the raw material product and can form a V shape with the contact hemisphere 207, thereby ensuring the stability of the paint.

[0024] The coating assembly 2 includes a coating shell 204, the upper part of the coating shell 204 is detachably connected to the upper cover 203, the middle part of the upper cover 203 is fixedly connected to the coating inlet pipe 201, the interior of the coating shell 204 is fixedly connected to the filter screen plate 202, the coating shell 204 is in an inverted triangle shape, the bottom of the coating shell 204 is provided with a contraction cavity 206, the contraction cavity 206 is gradually contracted from top to bottom, and an air bag 205 that can block the coating is provided in the contraction cavity 206. The air bag 205 is overall in an elongated shape and is adapted to the inner cavity of the coating shell 204. The air bag 205 is interconnected with an external air source, and the lower part of the contraction cavity 206 is provided with a coating port, and the coating port is fixedly connected to a contact hemisphere 207;

[0025] refer to Figure 1 、 Figure 2 、 Figure 3 During the coating operation, the electric push rod 104 drives the coating shell 204 and the upper cover 203 to move downward, and the external coating enters from the coating inlet tube 201, passes through the filter plate 202, and then falls, passes through the air bag 205 and enters the contraction cavity 206. When it is necessary to control the flow of the coating, the external air source is injected into the air bag 205, and the gas inside the air bag 205 becomes more, and then the volume becomes larger, thereby reducing the flowable space. The greater the air pressure, the smaller the flow. The air pressure value can be displayed by an existing barometer, and the outer circular surface of the contact hemisphere 207 is arc-shaped, which can guide the fabric product to each other, reducing the contact area between the contact hemisphere 207 and the fabric, thereby reducing the coating adhesion on the contact hemisphere 207, saving coating materials, saving costs, and being easy to use.

The length of the blowing nozzle 106 is greater than the length of the coating assembly 2, and the lower part of the blowing nozzle 106 has a blowing port.

[0027] refer to Figure 2 During the air drying operation, the hot air blower 107 is powered on to generate a hot air flow which passes through the connecting air duct 105 into the blowing nozzle 106 and is blown out from the blowing port, thereby drying the paint on the fabric, further solidifying the paint and improving the coating quality.

[0028] By setting up the coating component 2, the inflation amount in the airbag 205 is controlled, which can increase the volume of the airbag 205, thereby reducing the flow rate of the paint and controlling the amount of paint, thereby saving coating costs and facilitating use; by setting up the preheating box plate 102, the bottom of the product can be preheated, thereby accelerating the drying and solidification of the paint and improving the coating quality.

[0029] Working principle: The external hot water source enters the preheating box plate 102 from the water inlet pipe. The preheating box plate 102 can contact the bottom of the raw glass fiber cloth product, so that the paint falling on its surface is heated, which plays the role of preheating and accelerating solidification, improving the quality of coating, and preventing the paint from flowing. The guide roller 103 can guide the movement of the raw material product and form a V shape with the contact hemisphere 207 to ensure the stability of the coating. During the coating operation, the electric push rod 104 drives the coating shell 204 and the upper cover 203 to move downward, and the external paint enters from the paint inlet pipe 201, passes through the filter plate 202, and then falls, passes through the air bag 205 and enters the contraction chamber 206. When it is necessary to control the flow of the paint, The external air source is injected into the airbag 205, the gas inside the airbag 205 becomes more, and then the volume becomes larger, thereby reducing the flowable space. The greater the air pressure, the smaller the flow rate. The air pressure value can be displayed by an existing barometer, and the outer circular surface of the contact hemisphere 207 is arc-shaped, which can guide the fabric product to each other, reducing the contact area between the contact hemisphere 207 and the fabric, thereby reducing the adhesion of the paint on the contact hemisphere 207, saving paint materials, saving costs, and being easy to use. During the air drying operation, the hot air blower 107 is powered on to generate a hot air flow through the connecting air duct 105 into the blowing nozzle 106 and blown out from the blowing port, which can air-dry the paint on the fabric, further solidify the paint, and improve the coating quality.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
