DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Please refer to Figures 1-6 The present application provides a technical scheme:

[0025] Please refer to Figures 1-6 As shown in the figure, a glass fiber cloth sticking tool includes a bearing platform 1, the upper portion of the bearing platform 1 is provided with a mounting block 13, the mounting block 13 is rotatably connected with a compression roller 2, a flow guide pipe 5 is arranged on one side of the compression roller 2, the shape of the flow guide pipe 5 is set as an inverted U type, the flow guide pipe 5 is fixedly installed with a first mounting plate 11 and a second mounting plate 12, the first mounting plate 11 and the second mounting plate 12 are both fixedly installed with an extension pipe 3, the other end of the extension pipe 3 is fixedly installed on the mounting block 13, the extension pipe 3 is composed of a slide rod and a sleeve, the slide rod and the sleeve are fixedly installed with a first contraction spring 4; a second scraper 7 is fixedly installed on one side of the flow guide pipe 5 close to the compression roller 2, the top of the second scraper 7 is fixedly installed with a first scraper 6, the first scraper 6 and the second scraper 7 form an included angle, a plurality of through holes 8 are arranged on one side of the first scraper 6 close to the second scraper 7, the side of the first scraper 6 and the second scraper 7 away from the compression roller 2 is in abutment with the compression roller 2, the first scraper 6 and the second scraper 7 are both arranged in an inclined manner.

[0026] After spraying, the coating glue on the surface of the glass fiber cloth may have uneven thickness, and the pressure roller 2 can flatten the coating to some extent, making the coating more evenly distributed between the tooling and the glass fiber cloth. When the pressure roller 2 rotates clockwise, the outer wall of the pressure roller 2 will first abut the sharp side of the first scraper 6, and the pressure roller 2 will rub against the first scraper 6 when it rolls, allowing the first scraper 6 to clean the glue on the pressure roller 2 for the first time. The second scraper 7 is below the first scraper 6, and the sharp side of the second scraper 7 also abuts the outer wall of the pressure roller 2. The second scraper 7 can clean the glue for the second time. The glue scraped off by the first scraper 6 flows into the flow guide pipe 5, and the glue of the second scraper 7 flows through the through hole 8 to the flow guide pipe 5, and then flows out from both ends of the flow guide pipe 5. The first scraper 6 and the second scraper 7 are always in contact with the surface of the pressure roller 2, continuously and stably playing the role of glue scraping and cleaning, without the need to stop for cleaning, avoiding production interruption caused by equipment start and stop, saving time, allowing the production line to always run, improving the sticking yield of glass fiber cloth per unit time, and greatly improving production efficiency. At the same time, the surface of the pressure roller 2 can be cleaned in time to prevent glue from accumulating and drying on the surface of the pressure roller 2, thereby maintaining the flatness and smoothness of the surface of the pressure roller 2. If glue accumulates on the surface of the pressure roller 2, it will change the surface profile, causing uneven force on the glue during rolling, resulting in uneven distribution of glue on the glass fiber cloth, and causing local over-thickness or under-thickness, affecting the bonding quality of the product.

[0027] The glue flowing out of the flow guide pipe 5 can be collected and recycled using a collection box.

[0028] Referring to Figure 4 , the cross section of the first scraper 6 and the second scraper 7 is trapezoidal, and the sharp side of the first scraper 6 and the second scraper 7 abuts the outer wall of the pressure roller 2.

[0029] The cross section of the first scraper 6 and the second scraper 7 is trapezoidal, and the sharp side abuts the outer wall of the pressure roller 2. This shape can well fit the curved surface of the pressure roller 2, and in the glue scraping process, the sharp side can tightly contact the glue on the pressure roller 2, ensuring that the glue is fully scraped off and there is no missed glue due to poor fit between the scraper and the pressure roller 2, thereby improving the precision and effect of glue scraping.

[0030] Referring to Figure 4 , the material of the first scraper 6 and the second scraper 7 is spring steel, and the included angle between the first scraper 6 and the second scraper 7 is 20 degrees.

[0031] The 20° angle between the first scraper 6 and the second scraper 7 facilitates their coordinated work. During scraping, the glue is driven by the pressure roller 2 through the scrapers. This small angle allows the glue to flow orderly between the two scrapers. First, a portion of the glue is initially scraped off by the first scraper 6. Then, guided by the 20° angle, the remaining glue is smoothly scraped off by the second scraper 7, thereby improving the efficiency and thoroughness of scraping.

[0032] See Figure 3 The lengths of the first scraper 6 and the second scraper 7 are greater than that of the pressure roller 2.

[0033] The lengths of the first scraper 6 and the second scraper 7 are greater than that of the pressure roller 2. This allows the scraper to completely cover the axial length of the pressure roller 2 during the glue scraping process. Regardless of the distribution range of the glue on the pressure roller 2, the scraper can scrape off all the glue on the surface of the pressure roller 2. This avoids the situation where the glue at both ends or other positions of the pressure roller 2 cannot be scraped off due to insufficient scraper length, thus ensuring the integrity of glue scraping.

[0034] A longer scraper can better handle the glue on the edge of the pressure roller 2. If the scraper length is the same as or less than the pressure roller 2, the glue is likely to accumulate on the edge of the pressure roller 2 because the glue in these positions may not be effectively scraped off. However, a scraper that is longer than the pressure roller 2 can extend beyond the edge of the pressure roller 2, effectively scraping off the glue on the edge and preventing the glue from accumulating on the edge, thus further optimizing the glue scraping effect.

[0035] See Figures 1-2 A second contraction spring 9 and a guide telescopic rod 10 are fixedly installed between the mounting block 13 and the bearing platform 1. The second contraction spring 9 is sleeved on the outside of the guide telescopic rod 10, and the pressure roller 2 abuts against the glass fiber cloth.

[0036] The combination of the second contraction spring 9 and the guide telescopic rod 10 enables the pressure roller 2 to adaptively apply pressure to the fiberglass cloth. After the adhesive is sprayed onto the fiberglass cloth, uniform pressure is crucial for the spread of the adhesive. When the pressure roller 2 rolls, the pressure applied by the pressure roller 2 to the cloth surface remains relatively uniform because the second contraction spring 9 can adjust the pressure according to the slight undulations and unevenness of the fiberglass cloth surface. This uniform pressure can evenly squeeze and spread the adhesive, avoiding the situation where the adhesive accumulates or is not fully spread in some areas due to excessive or insufficient local pressure. For example, without this pressure adjustment mechanism, when the fiberglass cloth has slight wrinkles, the pressure roller 2 may apply excessive pressure to the wrinkles, causing too much adhesive to be squeezed to both sides of the wrinkles, resulting in uneven distribution of adhesive.

[0037] The guide telescopic rod 10 ensures that the pressure roller 2 moves vertically up and down, so that the pressure direction of the pressure roller 2 on the fiberglass cloth is always perpendicular to the cloth surface. This helps to squeeze the glue vertically onto the cloth surface and prevents the glue from flowing obliquely on the cloth surface due to pressure direction deviation, thereby further ensuring that the glue can be evenly distributed on the entire surface of the fiberglass cloth.

[0038] See Figures 1-2 A glue spraying device 14 is provided on one side of the pressure roller 2. The glue spraying device 14 is fixedly installed on the top of the bearing platform 1. A roll unwinding mechanism 15 is provided on one side of the glue spraying device 14.

[0039] By placing the glue spraying device 14 and the unwinding mechanism 15 on one side of the pressure roller 2, the process of bonding fiberglass cloth is made more continuous. After the fiberglass cloth is released from the unwinding mechanism 15, it directly enters the working area of ​​the glue spraying device 14 for glue spraying.

[0040] See Figures 1-2 On the other side of the pressure roller 2, a cutting mechanism 16 is provided. The cutting mechanism 16 is fixedly installed on the top of the bearing platform 1. Multiple cylinders are fixedly installed on the inner top wall of the cutting mechanism 16, and the telescopic end of the cylinder is connected to a cutting blade.

[0041] The cutting mechanism 16 is set on the other side of the pressure roller 2, so that the glass fiber cloth can be cut immediately after the adhesive is sprayed, forming a continuous production process. During the operation of the tooling, the glass fiber cloth is released from the unwinding mechanism 15, sprayed with adhesive by the adhesive spraying device 14, pasted by the pressure roller 2, and finally cut by the cutting mechanism 16. The whole process is completed in one go, without the need to transfer the pasted glass fiber cloth to other equipment for cutting, reducing the time wasted in the intermediate links and greatly improving production efficiency.

[0042] See Figures 1-2 The through holes 8 are linearly and equidistantly opened on the first scraper 6, and the guide pipe 5 is located below the through holes 8.

[0043] The equidistant linear through holes 8 can guide the flow of glue on the squeegee in an orderly manner. When the glue is scraped onto the first squeegee 6, the through holes 8 provide a clear flow path for the glue, avoiding disorderly accumulation of glue on the squeegee and blockage. If the glue is blocked on the squeegee surface, it will affect the glue scraping effect and the uniform distribution of glue. The presence of through holes 8 can effectively avoid this situation and improve the glue scraping efficiency of the squeegee.
