[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Embodiment 1

[0024] A glass fiber sizing agent coating device, comprising a rubber roller 4, a rubber box, the rubber roller 4 is located in the rubber box and is rotationally connected with the rubber box, the rubber box comprises an upper cover 1, a lower cover 2,

[0025] The front end of the upper cover 1 is provided with a baffle 3, the baffle 3 is inclined downward, and the orthographic projection of the baffle 3 can completely cover the rubber roller 4;

[0026] A plurality of air guide slots 31 are formed in the baffle 3, the air guide slots 31 are arranged in parallel with the rubber roller 4, and at least one air guide slot 31 is located on the side of the rubber roller 4 close to the upper cover 1.

[0027] Working principle: the device for preparing glass fiber drawing and coating in the utility model is based on the existing device, and the use method is the prior art, which will not be repeated here. The improvement of the utility model is that the baffle 3 is newly added at the end of the upper cover 1, which protects the rubber roller 4,

[0028] When there is a large amount of cooling water or water vapor on the coating device for spraying, a hot flow blowing downward will be formed, which will blow to the rubber roller 4, causing the sizing agent on the rubber roller 4 to be blown away, or water droplets to be blown to the rubber roller 4, so that the sizing agent cannot be well fused with the glass fiber bundle. Therefore, the innovation of the utility model is that the baffle 3 is arranged at the front end of the upper cover 1, and a plurality of air guide slots 31 are formed in the baffle 3. The arrangement of the air guide slots 31 will make the hot flow flow to the air guide slots 31, thereby reducing the impact on the rubber roller 4. In this way, the sizing agent on the rubber roller 4 will not be blown away, and water droplets will not be brought to the rubber roller 4, thereby maintaining good coating effect.

[0029] In the embodiment, at least one air guide slot 31 is close to the front end of the upper cover 1, and the orthographic projection of the air guide slot 31 is located between the upper cover 1 and the rubber roller 4. In this way, the hot flow can quickly flow out from the air guide slot 31 at the front end, that is, the flow path of the hot flow is changed, and the probability of the hot flow flowing to the rubber roller 4 is reduced.

[0030] In the embodiment, the low end of the front end face of the baffle 3 has a cofferdam 33 with a middle high and two ends low, for example, the cofferdam 33 can be designed as an inverted V-shaped or inverted U-shaped structure; in this way, the water flow possibly attached to the inner side of the baffle 3 can be quickly guided to the low ends of the two sides of the cofferdam 33 and discharged from the two sides, without gathering in the middle of the cofferdam 33, so that the water flow can be more completely discharged, avoiding the influence of the water flow on the rubber roller 4.

[0031] In the embodiment, the end of the cofferdam 33 is turned up to the inner side face of the baffle 3 and forms a water collecting groove 32; the two ends of the water collecting groove 32 are connected with a drain pipe 34; in this way, the water flow collected at the low end can be temporarily stored in the water collecting groove 32 and guided by the water collecting groove 32 to the drain pipe 34, so that the water flow can be discharged, and the water flow can be more completely guided and discharged, reducing the influence on the rubber roller 4.

[0032] In the embodiment, the inner side face of the baffle 3 is arc-shaped or linear; in this way, the water flow direction and flow rate can be better promoted, so that the influence on the rubber roller 4 is reduced.

[0033] The above is only the preferred embodiment of the utility model and is not used for limiting the utility model, for the person skilled in the art, the utility model can have various changes and changes.
