[0028] Refer to Figure 1 , Figure 1 shows a schematic structural diagram of a glue scraping plate in an embodiment of the present utility model. An embodiment of the present utility model provides a glue scraping plate for use in a sizing pre-impregnating machine. The glue scraping plate includes a square shaft 100 and a scraping plate 200. The square shaft 100 is connected to the sizing pre-impregnating machine, and the angle of the square shaft 100 is adjustable; the scraping plate 200 is detachably connected to the square shaft 100. At least one glue scraping edge 210 is formed on the scraping plate 200. The extending direction of the glue scraping edge 210 is the same as the extending direction of the square shaft 100. The glue scraping edge 210 can act on the glass cloth to scrape off the excess glue.
[0029] The present technical solution provides a glue scraping plate. Among them, the square shaft 100 is connected to the sizing pre-impregnating machine, and the angle of the square shaft 100 is adjustable. At least one glue scraping edge 210 is provided on the scraping plate 200 so that the excess glue on the glass cloth can be scraped off by the glue scraping edge 210 on the scraping plate 200. By detachably connecting the scraping plate 200 and the square shaft 100, after the glue scraping edge 210 on the scraping plate 200 is worn, it is convenient to replace the new scraping plate 200, or after the scraping plate 200 is detached from the square shaft 100, the glue can be scraped directly by the edge of the square shaft 100. In this way, compared with the prior art of detaching the square shaft 100, the disassembly and assembly time is saved, and moreover, the price of the scraping plate 200 is cheaper than that of the square shaft 100, so the production cost is also reduced.
[0030] In one embodiment, the squeegee 200 is configured with a flat square structure. The length direction of the squeegee 200 is consistent with the extending direction of the square shaft 100. One of the edges of the flat square structure is configured as the glue scraping edge 210.
[0031] By configuring the squeegee 200 into a flat square structure, on the one hand, it is easy to form the glue scraping edge 210 on the flat square structure. On the other hand, the flat square structure is easy to be connected to the square shaft 100. In addition, it occupies less space. By setting the length direction of the squeegee 200 to be consistent with the extending direction of the square shaft 100, it is convenient to form the glue scraping edge 210 in the extending direction of the square shaft 100.
[0032] Further, one end of the squeegee 200 in the width direction extends out of the side surface of the square shaft 100. The edge of the extended end of the squeegee 200 away from the edge of the square shaft 100 is configured as the glue scraping edge 210. By setting one end of the squeegee 200 in the width direction to extend out of the side surface of the square shaft 100 and configuring the edge of the extended end away from the edge of the square shaft 100 as the glue scraping edge 210, so that the glue scraping edge 210 is located at the most prominent position after the squeegee 200 is connected to the square shaft 100, thus facilitating adjusting the angle of the square shaft 100 to make the glue scraping edge 210 contact the glass cloth, so as to facilitate scraping the glue liquid on the glass cloth.
[0033] In one embodiment, both ends of the squeegee 200 in the width direction extend out of the two opposite side surfaces of the square shaft 100. The edges of the two extended ends of the squeegee 200 away from the edge of the square shaft 100 are configured as the glue scraping edges 210. By making both ends of the squeegee 200 in the width direction extend out of the two opposite side surfaces of the square shaft 100 and configuring the edges of the two ends of the squeegee 200 extending out of the side surface of the square shaft 100 away from the edge of the square shaft 100 as the glue scraping edges 210, so that there are two glue scraping edges 210 on the same squeegee 200. When one glue scraping edge 210 is worn, by adjusting the angle of the square shaft 100, the other glue scraping edge 210 corresponds to the glass cloth, so that the glue liquid can be scraped off without disassembling the squeegee 200. While saving time, the squeegee 200 can be reused multiple times, thus saving the production cost.
[0034] In one embodiment, the four edges at both ends of the squeegee 200 in the width direction are configured as glue scraping edges 210. In this embodiment, the four edges at both ends of the squeegee 200 in the width direction are all set as glue scraping edges 210, so that after the two opposite edges on one side are worn, by removing the squeegee 200 from the square shaft 100 and then turning it over, the other side faces outward, so that the remaining two glue scraping edges 210 can be used to scrape off the glue on the glass cloth. Until all the glue scraping edges 210 are worn, the squeegee 200 can be removed from the square shaft 100, and another squeegee 200 can be replaced or the edge of the square shaft 100 can be directly used to scrape off the glue.
[0035] In one embodiment, the squeegee 200 and the square shaft 100 are fixedly connected by bolts. Specifically, a plurality of through holes 220 are arranged at intervals along the length direction of the squeegee 200, and a plurality of bolt holes corresponding to the through holes 220 are arranged on one side of the square shaft 100. Bolts pass through the through holes 220 and are in threaded cooperation with the bolt holes. The number of bolts corresponds to the number of through holes 220. Connecting the squeegee 200 and the square shaft 100 by bolts has a simple structure, is convenient for production and processing, and is also convenient for disassembly, thereby reducing the disassembly time and lowering the production cost. By arranging a plurality of through holes 220 at intervals along the length direction of the squeegee 200 and arranging a plurality of threaded holes corresponding to the through holes 220 on the square shaft 100, it is convenient to connect with bolts. In this embodiment, 9 through holes 220 are arranged on the squeegee 200, and M8 bolts are used.
[0036] In one embodiment, the material of the squeegee 200 is stainless steel. Specifically, the length of the squeegee 200 is configured to be 1600 mm, the width is configured to be 60 mm, and the thickness is configured to be 8 mm. Selecting the material of the squeegee 200 as stainless steel, on the one hand, it has high strength and wear resistance. In addition, stainless steel has strong anti-rust ability, which is beneficial to ensuring the service life of the squeegee 200 in the glue scraping process.
[0037] An embodiment of the present utility model further provides a sizing and impregnating machine, which includes the squeegee plate as described above. In this embodiment, the above-mentioned squeegee plate is applied to the sizing and impregnating machine. The squeegee plate is connected to the sizing and impregnating machine by connecting the square shaft 100, and the angle of the square shaft 100 is adjustable. At least one sizing edge 210 is provided on the squeegee 200 so that the excess glue on the glass cloth can be scraped off by the sizing edge 210 on the squeegee 200. By detachably connecting the squeegee 200 and the square shaft 100, after the sizing edge 210 on the squeegee 200 is worn, it is convenient to replace the new squeegee 200, or after the squeegee 200 is detached from the square shaft 100, the glue can be scraped directly by the edge of the square shaft 100. In this way, compared with the prior art of disassembling the square shaft 100, the disassembly and assembly time is saved, and the price of the squeegee 200 is cheaper than that of the square shaft 100, so the production cost is also reduced.
[0038] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0039] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
