[0002] Prepreg is a kind of material form commonly used in composite material manufacturing, especially in the fields of manufacturing printed circuit board, aerospace and sports goods, etc., which is a sheet material made of fiber reinforced material (such as glass fiber, carbon fiber, etc.) soaked in partially cured thermosetting resin (such as epoxy resin).

[0003] In the process of producing and processing the prepreg, the glass fiber cloth needs to be treated by immersion, and is completely immersed in the resin glue solution. When the glass fiber cloth enters the glue tank, it inevitably carries a small amount of air. These air is released and rises in the glue solution, forming bubbles. These bubbles have a high degree of adhesion and are easy to adhere to the surface of the glass fiber cloth, thereby causing adverse effects on the appearance of the product. SUMMARY

DETAILED DESCRIPTION

[0018] The preferred technical scheme of the utility model is described in detail below in combination with the drawings.

[0019] A glue tank bubble blocking device of gluing machine, like Figures 1-4As shown, the system includes a glue tank 1, an overflow tank 2, a drive roller 3, a fiberglass cloth 4, a mounting base 5, a rotating wheel 6, a belt 7, a motor 8, a reciprocating screw 9, a sliding frame 10, a scraper 11, an adjusting mechanism, and a guide rod 14. The glue tank 1 has overflow tanks 2 on both its left and right sides. Multiple notches are opened at the connection points between the glue tank 1 and the overflow tanks 2 on both sides. The glue tank 1 contains glue liquid. Two drive rollers 3 are rotatably mounted inside the glue tank 1. The fiberglass cloth 4 enters the glue liquid from the left side of the glue tank 1, passes around the outside of the two drive rollers 3, and exits the glue liquid from the right side of the glue tank 1. Mounting bases 5 are located on both the front and rear sides of the left side of the glue tank 1. Rotating wheels 6 are located on the left and right sides of the opposite side of the two mounting bases 5. The point where the cloth 4 enters the adhesive is located between two rotating wheels 6 on the left and right sides. A motor 8 is installed on the rear side of the adhesive tank 1. The output shaft of the motor 8 is connected to one of the rotating wheels 6 on the rear side of the adhesive tank 1. A belt 7 is wound around the outside of the two rotating wheels 6 on the rear side of the adhesive tank 1. A reciprocating screw 9 is connected between the rotating wheels 6 on the front and rear sides of the adhesive tank 1. The point where the glass fiber cloth 4 enters the adhesive is located between the two reciprocating screws 9. A sliding frame 10 is threaded onto both reciprocating screws 9. An adjustment mechanism is installed on the sliding frame 10. The adjustment mechanism is connected to the scraper 11. The lower side of the scraper 11 is slightly lower than the liquid surface. Two guide rods 14 are connected between the mounting seats 5 on the front and rear sides of the adhesive tank 1. The sliding frame 10 is slidably connected to the guide rods 14.

[0020] In use, the motor 8 drives the rotating wheel 6 connected to its output shaft to rotate. The rotating wheel 6 drives another rotating wheel 6 on the same side to rotate via the belt 7. The rotating wheel 6 drives the reciprocating screw 9 to rotate. As the reciprocating screw 9 rotates, the sliding frame 10 threaded onto it will move back and forth. The sliding frame 10 drives the scraper 11 to move together. When the scraper 11 moves, it will scrape off the air bubbles on the surface of the adhesive, so that it does not come into contact with the fiberglass cloth 4 and affect the appearance of the product. When the liquid level drops or rises, the height of the scraper 11 can be adjusted by the adjustment mechanism to ensure that the scraper 11 is always in the best position to scrape off the air bubbles.

[0021] like Figure 4 As shown, the adjustment mechanism includes an adjusting screw 12 and an adjusting frame 13. The adjusting screw 12 is threadedly connected to the upper side of the sliding frame 10, and the adjusting frame 13 is rotatably connected to the lower side of the adjusting screw 12. The sliding frame 10 has two through holes in the middle in the vertical direction. The adjusting frame 13 has two sliding rods on its lower side, which are slidably connected to the two through holes of the sliding frame 10 respectively. The lower side of the adjusting frame 13 is connected to the scraper 11. When it is necessary to adjust the height of the scraper 11, the height of the adjusting frame 13 connected to the scraper 11 is adjusted up and down by rotating the adjusting screw 12, thereby realizing the adjustment of the height of the scraper 11.

[0022] like Figure 4As shown, the device also comprises guide plates 111, and the lower side of the scraper 11 is provided with a plurality of guide plates 111, which are uniformly arranged from left to right and gradually increase in length; the guide plates 111 help to more effectively guide and disperse the glue flow, reduce the resistance when the scraper 11 moves, reduce the energy consumption of the motor 8, and improve the work efficiency.

[0023] The scraper 11 is isosceles trapezoidal in shape, and one side close to the glass fiber cloth 4 is longer; since one side of the scraper 11 is longer, when the scraper 11 moves on the glue surface, it can effectively push the bubbles away from the glass fiber cloth 4, ensuring that the bubbles will not adhere to the glass fiber cloth 4 when scraping.

[0024] The moving range of the scraper 11 in the front-rear direction is greater than the width of the glass fiber cloth 4, ensuring that the scraper 11 can cover and process the glue surface of the entire peripheral area of the glass fiber cloth 4, reducing dead angles, and when the scraper 11 reaches the bottom of one side and moves in the opposite direction, the side of the scraper 11 may be attached to some bubbles, which will gradually detach during the movement of the scraper 11; a larger range can reduce the appearance of these bubbles in the peripheral area of the glass fiber cloth 4, reducing the possibility of bubble adhesion.

[0025] The lower side of the mounting seat 5 is provided with a slope matching the shape of the side surface of the scraper 11, and the slope is provided with a rubber pad, which can absorb the impact force generated by the reciprocating movement of the scraper 11, play a buffering role, and improve the service life of the equipment.

[0026] It should be understood that the embodiments are only used to illustrate the present application and not to limit the scope of the present application. In addition, it should be understood that after reading the content taught by the present application, those skilled in the art can make various changes or modifications to the present application, and these equivalent forms also fall within the scope defined by the claims attached to the present application.
