Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiberglass cloth processing technology, and in particular to a resin-impregnated fiberglass cloth winding device with a guide groove. Background Technology
[0002] Resin-impregnated fiberglass cloth (prepreg) is a key intermediate material in composite material manufacturing, widely used in aerospace, wind turbine blades, and automotive lightweighting. In its production process, the fiberglass cloth needs to be impregnated with resin, guided, and wound to form a uniform prepreg roll.
[0003] In existing technologies, traditional fiberglass cloth winding devices require scraping the resin on the surface of the fiberglass cloth to ensure that excess resin is not wasted during the winding process. Therefore, scrapers and guide channels are needed. However, most traditional scrapers are straight plates. When scraping the resin, the resin is scraped in the opposite direction of winding. Although this can achieve the scraping effect, it cannot be discharged. The accumulation of resin will affect the normal winding. Therefore, this utility model proposes a resin-impregnated fiberglass cloth winding device with guide channels to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a resin-impregnated fiberglass cloth winding device with a guide groove.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A resin-impregnated fiberglass cloth winding device with guide grooves includes a base. Two symmetrically arranged support plates are fixedly connected to the upper end of the base. A winding roller is rotatably connected between the two support plates. A scraping mechanism for scraping the cloth wound by the winding roller is provided between the two support plates. The scraping mechanism includes a scraper fixedly connected between the two support plates. The scraper is designed in a "V" shape, and a guide groove is opened on the front side wall of the scraper. The guide groove is designed in a "V" shape and distributed on the front side of the scraper. A collection box is provided at the upper end of the base. A stirring mechanism for stirring the material is provided in the collection box.
[0007] Preferably, the stirring mechanism includes a rotating rod rotatably connected between the inner walls of both ends of the collection box, and a plurality of equally spaced stirring blades are fixedly connected to the side wall of the rotating rod.
[0008] Preferably, a motor is fixedly connected to the side wall of one of the support plates, and the end of the output shaft of the motor is fixedly connected to the end of the take-up roller.
[0009] Preferably, the output shaft of the motor and the end of the rotating rod are both fixedly fitted with synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt drive.
[0010] Preferably, the lower end of the base is provided with an anti-slip pad, and the anti-slip pad is made of rubber.
[0011] Preferably, the inner walls at both ends of the guide channel are provided with inclined surfaces.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. By setting up a scraper with a "V" shape design, during the winding of the fiberglass cloth, the resin sprayed from the nozzle remains on the upper part of the fiberglass cloth. When the fiberglass cloth passes through the scraper, the scraper can scrape up the excess resin on the upper part of the fiberglass cloth, and under the action of the "V" shaped scraper, the excess resin is scraped to both sides, avoiding the accumulation of resin on the fiberglass cloth and affecting normal winding. At the same time, the design of the guide channel and the inclined surface allows the scraped resin to enter the guide channel and flow into the collection box under the action of the inclined surface, realizing the collection of excess resin.
[0014] 2. By setting up a stirring mechanism, during the winding process, the output shaft of the drive motor rotates, driving the winding roller to wind up the fiberglass cloth. During this process, under the transmission of the synchronous pulley and synchronous belt, the rotating rod rotates, driving the stirring blade to rotate, thereby stirring the scraped resin and preventing the resin from solidifying and settling.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0022] Reference Figure 1-5 A resin-impregnated fiberglass cloth winding device with a guide groove includes a base 1. Two symmetrically arranged support plates 3 are fixedly connected to the upper end of the base 1. A winding roller 4 is rotatably connected between the two support plates 3. A scraping mechanism for scraping the cloth wound by the winding roller 4 is provided between the two support plates 3. The scraping mechanism includes a scraper 10 fixedly connected between the two support plates 3. The scraper 10 has a "V" shape design, and a guide groove 11 is opened on the front side wall of the scraper 10. The guide groove 11 has a "V" shape design and is distributed on the front side of the scraper 10. A collection box 2 is provided at the upper end of the base 1.
[0023] In this utility model, a stirring mechanism for stirring materials is provided inside the collection box 2. The stirring mechanism includes a rotating rod 9 rotatably connected between the inner walls of both ends of the collection box 2. Multiple sets of equally spaced stirring blades 8 are fixedly connected to the side wall of the rotating rod 9. A motor 6 is fixedly connected to the side wall of one of the support plates 3. The end of the output shaft of the motor 6 is fixedly connected to the end of the winding roller 4.
[0024] In this utility model, the output shaft of the motor 6 and the end of the rotating rod 9 are both fixedly sleeved with synchronous pulleys 7. The two synchronous pulleys 7 are connected by a synchronous belt 5. The lower end of the base 1 is provided with an anti-slip pad. The anti-slip pad is made of rubber. Under the action of the anti-slip pad, the friction between the base 1 and the ground can be increased, thereby improving the stability of the device.
[0025] In use, the output shaft of the drive motor 6 rotates, driving the winding roller 4 to wind the fiberglass cloth. The scraper 10 is designed in a "V" shape. During the winding process of the fiberglass cloth, the resin sprayed from the nozzle remains on the upper end of the fiberglass cloth. When the fiberglass cloth passes the scraper 10, the scraper 10 can scrape up the excess resin on the upper end of the fiberglass cloth. Under the action of the "V" shaped scraper 10, the excess resin is scraped to both sides to prevent the resin from accumulating on the fiberglass cloth and affecting normal winding. At the same time, with the design of the guide groove 11 and the inclined surface 12, the scraped resin can enter the guide groove 11 and flow into the collection box 2 under the action of the inclined surface 12, realizing the collection of excess resin. During the winding process, under the transmission of the synchronous wheel 7 and the synchronous belt 5, the rotating rod 9 rotates, driving the stirring blade 8 to rotate, realizing the stirring of the scraped resin and preventing the resin from solidifying and settling.
