Description

Technical Field

[0001] The utility model relates to the technical field of fiber production and processing, and particularly relates to a fiber dipping device. Background Art

[0002] Due to its excellent strength, corrosion resistance and light weight characteristics, glass fiber has become an important reinforcing material. However, the mechanical properties and durability of single glass fiber are limited. Therefore, it is necessary to combine it with adhesives such as resin through a dipping process to improve the overall performance of the material.

[0003] In the prior art, through retrieval, it is found that the Chinese patent discloses "a composite fiber deep dipping device" with the application number "201920394335.4". The above patent mainly includes a fiber roller, a fiber heater, a separator and a dipping tank; the fiber roller is located at the front end of the fiber heater, the fiber heater is located at the front end of the dipping tank, and the separators are symmetrically distributed at both ends of the dipping tank; dipping rods are installed at the bottom end inside the dipping tank. Although the above utility model has a simple structure and is convenient to use, it can not only evenly soak the sizing agent between the composite fiber raw materials, but also improve the dipping effect and ensure the quality of the fiber. However, by directly immersing the fiber in the sizing agent, the sizing amount on the fiber surface cannot be precisely controlled. The fiber will be affected by various factors during the immersion process, such as immersion time, sizing agent concentration, fiber moving speed, etc. All these may lead to inconsistent sizing agent amounts on the fiber surface. Too much or too little sizing agent amount will affect the dipping effect, and further affect the subsequent processing and use performance of the fiber. Therefore, the utility model provides a fiber dipping device to solve the problems raised in the above background art. Summary of the Utility Model

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1-3 , an embodiment of the present utility model provides a fiber impregnation device, which includes a box body 1, a mounting rack 6 provided on the top of the box body 1, and a glue receiving funnel 10. The inside of the box body 1 is a hollow structure to form a glue storage bin 2 for storing impregnating liquid. A plurality of impregnation components are provided between the glue storage bin 2 and the mounting rack 6 to ensure the efficiency of automated production. The plurality of impregnation components are arranged adjacent to each other in sequence;

[0023] The impregnation component includes an impregnation roller 3 installed inside the glue storage bin 2, pressure rollers 4 installed at the bottom of the mounting rack 6 and on both sides of the impregnation roller 3, a glue amount scraper 5 installed on one side of the box body 1 and close to the impregnation roller 3, a lower scraper 7 installed on one side of the box body 1 and opposite to the glue amount scraper 5, and an upper scraper 8 installed on one side of the mounting rack 6 and vertically opposite to the lower scraper 7. Two wing plates 9 are provided on the side of the lower scraper 7 and the upper scraper 8 close to each other. The four wing plates 9 are spaced apart, and the side of the wing plate 9 close to each other is an arc structure to prevent the wing plate 9 from damaging the moving glass fiber.

[0024] After the non-impregnated glass fiber is conveyed from the right side, the pressure roller 4 presses the glass fiber onto the surface of the impregnation roller 3. During the forward movement of the glass fiber, the impregnation roller 3 is driven to rotate. The glue liquid inside the glue storage bin 2 adheres to the surface of the impregnation roller 3, so that the glue liquid can be immersed into the glass fiber. The rotating impregnation roller 3 scrapes off the excess glue liquid on the surface of the impregnation roller 3 through the glue amount scraper 5, so that the amount of glue immersed into the glass fiber is the same when the glass fiber contacts the impregnation roller 3, which is beneficial to controlling the thickness of the glue liquid and enhancing the uniformity of the glue liquid. When the glass fiber passes through the lower scraper 7 and the upper scraper 8, the excess glue liquid on the surface of the glass fiber is scraped off. The wing plates 9 arranged between the lower scraper 7 and the upper scraper 8 play a role in scraping glue. The spaced wing plates 9 form two contact points up and down, which can further accurately control the thickness of the glue liquid, effectively ensuring the stability of the impregnation amount of the glass fiber continuously passing through the impregnation device and realizing automated and standardized production.

[0025] The glue receiving funnel 10 is provided on one side of the mounting rack 6 and above the glue storage bin 2 for filling the glue liquid into the glue storage bin 2. The conveying direction of the glass fiber to be impregnated moves from the glue amount scraper 5 to the side of the upper scraper 8, and the glass fiber passes through the bottom of the right pressure roller 4, the top of the impregnation roller 3, the bottom of the right pressure roller 4, and between the lower scraper 7 and the upper scraper 8 in sequence, ensuring the contact between the glass fiber and the glue liquid and the control of the glue amount on the glass fiber.

[0026] Working principle: The glass fiber passes through successively from the bottom of the right pressing roller 4, the top of the sizing roller 3, the bottom of the left pressing roller 4, and between the lower scraper 7 and the upper scraper 8;

[0027] After the non-sized glass fiber is conveyed from the right, the pressing roller 4 presses the glass fiber onto the surface of the sizing roller 3. During the forward movement of the glass fiber, the sizing roller 3 is driven to rotate. The sizing liquid inside the sizing liquid storage bin 2 adheres to the surface of the sizing roller 3, so that the sizing liquid can be immersed into the glass fiber. The rotating sizing roller 3 scrapes off the excess sizing liquid on the surface of the sizing roller 3 through the sizing amount scraper 5, so that the amount of sizing liquid immersed into the glass fiber is consistent when the glass fiber contacts the sizing roller 3, which is beneficial to controlling the thickness of the sizing liquid to enhance the uniformity of the sizing liquid. When the glass fiber passes through the lower scraper 7 and the upper scraper 8, the excess sizing liquid on the surface of the glass fiber is scraped off. The fin plate 9 is arranged between the lower scraper 7 and the upper scraper 8 to play a role in scraping the sizing liquid. The spaced fin plates 9 form two contact points up and down, which can further accurately control the thickness of the sizing liquid, and can effectively ensure the stability of the sizing amount of the glass fiber continuously passing through the sizing device, realizing automated and standardized production.

[0028] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
