Description

Technical Field

[0001] The utility model relates to the technical field of prepreg production equipment, in particular to a carbon fiber prepreg yarn spreading device. Background Art

[0002] Carbon fiber prepreg is an advanced composite material consisting of carbon fibers pre-impregnated with resin. During the manufacturing process, the carbon fibers are typically woven into cloth or otherwise arranged into sheets, then pre-impregnated with resin. This treatment makes the carbon fiber cloth easier to shape during use because the resin is partially cured while still retaining a certain degree of flexibility.

[0003] However, during the unwinding operation of carbon fiber prepreg, due to the characteristics of the prepreg, a small amount of prepreg will easily remain on the surface of the prepreg. During the unwinding process, the prepreg will adhere to the surface of the conveyor roller. The prepreg residue will affect the surface quality and friction characteristics of the conveyor roller, resulting in uneven stretching of the carbon fiber prepreg and fiber breakage. Therefore, a carbon fiber prepreg unwinding device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 and Figure 3An embodiment of the utility model provides a carbon fiber prepreg yarn spreading device, comprising: a mounting frame 10, a yarn feed port 13 and a yarn spreading roller 12, a plurality of yarn spreading rollers 12 are installed between the mounting frame 10, an ultrasonic vibrator 11 for controlling the yarn spreading roller 12 is installed on the outside of the mounting frame 10, and the number of ultrasonic vibrators 11 is the same as the number of yarn spreading rollers 12, a cleaning plate 15 is installed inside the mounting frame 10, the cleaning plate 15 is sleeved under one of the yarn spreading rollers 12, the cleaning plate 15 is located below the yarn feed port 13, a plurality of cleaning brushes 17 are evenly installed on the inside of the cleaning plate 15 through a plurality of elastic components 19, and a plurality of liquid outlets 18 are evenly opened on the inside of the cleaning plate 15.

[0020] According to the above technical solution, the mounting frame 10, the spreading roller 12 and the ultrasonic vibrator 11 constitute the spreading equipment of the carbon fiber prepreg, which can realize the spreading operation of the carbon fiber prepreg. The ultrasonic vibrator 11 can control the ultrasonic vibration to influence and optimize the spreading of the carbon fiber prepreg and the quality of the cloth, thereby improving the quality of the carbon fiber prepreg spreading. During operation, the cleaning brush 17 continuously contacts and wipes the surface of the spreading roller 12 as the spreading roller 12 rotates, scrapes the residual prepreg liquid and pushes it onto the cleaning plate 15. Then, the cleaning plate 15 discharges the removed liquid to the outside of the cleaning plate 15 through the liquid outlet 18, thereby achieving the function of cleaning the spreading roller 12, avoiding the prepreg liquid residue on the spreading roller 12 from affecting the spreading effect, and at the same time, avoiding the spreading efficiency affected by the breakage of the carbon fiber prepreg.

[0021] Furthermore, a yarn outlet for discharging yarn is provided on a side opposite to the yarn inlet 13 .

[0022] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the elastic component 19 includes a receiving groove 193, which is opened inside the cleaning plate 15, and the inside of the receiving groove 193 is fixedly connected to a spring 192, and the inside of the receiving groove 193 is slidably connected to a connecting block 191, and the side of the connecting block 191 away from the receiving groove 193 is fixedly connected to the cleaning brush 17.

[0023] According to the above technical solution, the cleaning brush 17 can move in the accommodating groove 193 by cooperating with the connecting block 191 and the spring 192, ensuring that the cleaning brush 17 can adapt to the shape of the surface of the yarn spreading roller 12 during the yarn spreading process and maintain appropriate contact pressure, thereby effectively cleaning the prepreg residue remaining on the surface of the yarn spreading roller 12, thereby improving the quality of the carbon fiber prepreg fabric spreading and avoiding situations such as fiber breakage.

[0024] In one embodiment of the present invention, Figure 2As shown, the cleaning plate 15 is constructed in an arc shape. Through this arrangement, the cleaning plate 15 can better adapt to the curved shape of the yarn spreading roller 12, ensuring that the cleaning brush 17 can fit the surface of the yarn spreading roller 12 to achieve a more effective cleaning effect.

[0025] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, an opening is provided at the top of the cleaning plate 15, and the diameter of the opening of the cleaning plate 15 is larger than the diameter of the yarn spreading roller 12. Through such a setting, the cleaning plate 15 can cover the outside of the yarn spreading roller 12, so that the cleaning brush 17 can clean the yarn spreading roller 12.

[0026] In one embodiment of the present invention, Figure 1 As shown, a recovery box 16 is installed inside the mounting frame 10, and the recovery box 16 is located below the cleaning plate 15. Through such a setting, the pre-impregnation liquid residue will fall directly into the recovery box 16 after being cleaned by the cleaning brush 17, avoiding the dripping or overflow of the pre-impregnation liquid in the working area, thereby ensuring the cleanliness of the working environment.

[0027] In one embodiment of the present invention, Figure 3 As shown, the cleaning brush 17 and the liquid outlet 18 are arranged at intervals. Through such an arrangement, it can be ensured that the liquid outlet 18 will not be affected by the cleaning brush 17, the liquid outlet 18 can be kept unobstructed and clean, and the pre-soak residue can be smoothly discharged from the cleaning plate 15.
