[0033] More specifically, the relative position of the third guide roller 673, the scraper main body 62 and the second guide roller 55 is adjusted by moving the second roller frame 671 along the pushing arm 64 (by cooperating the second adjusting groove 9 with the third screw 672), so that the cloth can be smoothly led out after scraping, and wrinkles or deviation caused by tension changes are avoided; the rotation direction of the third guide roller 673 is consistent with the cloth conveying direction, which reduces the friction on the surface of the cloth and protects the coating from being damaged.

[0035] More specifically, the core function of the input unit 7 is to provide pre-guiding for the cloth before entering the scraping area, to ensure the stability of the cloth conveying path, and the specific process is as follows: Synchronous distance adjustment: when the relative distance of the moving arm 53 is adjusted by the screw rod 52 to adapt to different thicknesses of the cloth, the moving arm 53 drives the third roller frame 71 to move synchronously, so that the distance between the pair of fourth guide rollers 72 is always consistent with the distance between the pair of second guide rollers 55 (because both are driven by the moving arm 53), ensuring that the limiting width on both sides of the cloth always matches the thickness of the cloth when the cloth enters the fourth guide roller and the second guide roller area, avoiding offset or wrinkles caused by improper width adaptation.

[0036] Multi-directional conveying guide: when the device is in a horizontal coating state, the axes of the fourth guide roller 72 and the second guide roller 55 are horizontally aligned, and after the cloth is guided by the fourth guide roller 72, it is conveyed horizontally to the right to the second guide roller 55 area, entering the doctor blade coating process; when the collecting structure 5 is adjusted to a vertical coating state by the turnover structure 4, the fourth guide roller 72 is synchronously turned over with the moving arm 53, its guiding direction is adaptively adjusted, cooperating with the second guide roller 55 to guide the cloth to turn upward, ensuring that the cloth can still be stable on the vertical path.

[0037] Cooperative guiding: the fourth guide roller 72 and the second guide roller 55 form a continuous guiding channel, and under the support and limiting of the two, the surface tension of the cloth is uniform, avoiding deformation caused by external forces during the conveying process, providing a flat substrate basis for the accurate doctor blade coating of the subsequent doctor blade coating structure 6.

[0038] The fourth guide roller 72 of the input unit 7 and the third guide roller 673 of the output unit 67 form a complete cloth conveying path: the length of the third guide roller 673 is greater than the length of the supporting plate 54, and it can penetrate the upper part of the middle part of the supporting plate 54, and it and the fourth guide roller 72 are respectively located on both sides of the doctor blade coating area, through the symmetrical guiding action, it ensures that the cloth always moves along the preset path during the entire doctor blade coating process, further improving the conveying stability.

[0039] The detailed connection means is a well-known technology in the art, and the working principle and process are described below. The specific work is as follows.

[0040] The glass fiber cloth is conveyed by an external traction mechanism, first guided by the first guide roller 3 on the base 1; then enters the input unit 7, and forms lateral limiting through the fourth guide roller 72 on the third roller frame 71, that is, it can enter between the two supporting plates 54 and be guided and output through the output unit 67 above the supporting plate 54, that is, guided and output by the third guide roller 673; According to the production requirements, when single-sided coating, adjust the orientation of the collecting structure 5 and the doctor blade coating structure 6 through the turnover structure 4: start the hydraulic cylinder main body 44, the extension end drives the rack 45 to descend, the rack 45 meshes with the gear 43 to drive the swing arm 42 to rotate, and then the other end of the swing arm 42 is turned over to horizontal on the wheel frame 41, at this time the two supporting plates 54 are symmetrically located on the upper and lower sides of the cloth; When double-sided coating, the reverse drive rack 45 guides the cloth upward through the output unit, vertically upward, and the supporting plate 54 is located on both sides of the cloth.

[0041] Then, the aggregate is matched with the cloth, for example, when double-sided coating: The existing glue is gathered: the closed area formed between the left baffle 51, the right baffle 58, the baffle 56, and the supporting plate 54 limits the silicone between the supporting plates 54, realizes the gathering of the glue, and the glue is located on both sides of the cloth; Thickness matching: rotating the screw rod 52 drives the moving arm 53 to move relatively on the left baffle 51, adjusts the distance between the supporting plate 54 and the second guide roller 55, so that it matches the thickness of the current glass fiber cloth, ensures that the cloth is stable and fully contacts the glue when passing through, and at the same time seals the space between the second guide rollers 55 to prevent leakage; At the same time, the movement of the moving arm 53 synchronously drives the fourth guide roller 72 of the input unit 7 to adjust the distance, so that the fourth guide roller 72 has the same distance as the second guide roller 55; and the moving arm 53 drives the supporting plate 54 to adjust the distance, which also relatively synchronously adjusts the distance of the scraping structure 6.

[0042] Scraping and thickness and width control: Coating thickness control: by sliding the sliding seat 61 in the trapezoidal groove 10 of the slide 57, and being fixed by the first bolt 63 passing through the first adjusting groove 8, the relative distance between the scraper main body 62 and the cloth is adjusted, and when the cloth passes, the scraper main body 62 scrapes the excess thickness of the silicone on the surface, so that the coating thickness is consistent with the preset distance; At the same time, in order to ensure the same double-sided scraping, the second roller frame 671 is moved by means of the second adjusting groove 9, and the third bolt 672 is fixed to adjust the distance of the third guide roller 673. Since the third guide roller 673 is located above the scraper main body 62, the cloth is limited to be vertically upwardly conveyed.
