Description

Technical Field

[0001] The utility model mainly relates to the technical field of carbon fiber prepreg production, and particularly relates to a device for manufacturing carbon fiber prepreg. Background Art

[0002] Carbon fiber prepreg is a composite material formed by compounding epoxy resin on carbon fiber through high-pressure and high-temperature technology. It is made of carbon fiber yarn, epoxy resin, release paper and other materials, and is processed through processes such as coating, hot pressing, cooling, film laminating, and winding. It is also known as carbon fiber prepreg.

[0003] When manufacturing carbon fiber prepreg, it is necessary to unroll the composite material. However, the existing device for manufacturing carbon fiber prepreg has poor unrolling effect. After searching, the patent with the publication number CN215882225U provides a device for manufacturing carbon fiber prepreg. In this device, the leveling blocks on the two first rotating shafts can drive the composite material on the conveyor belt to be leveled to both sides. However, the leveling blocks on the first rotating shaft of this device are at a 90° angle to the conveyor belt, which easily causes the material to be overstretched to both sides when the leveling block contacts the composite material, affecting the quality of the carbon fiber composite material. Summary of the Utility Model

[0004] The utility model mainly provides a device for manufacturing carbon fiber prepreg to solve the technical problems proposed in the above background art.

[0012] Furthermore, the center of the first gear is located on the axis of the connecting shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] For the embodiments, please refer to the attached Figures 1-3 , a device for manufacturing carbon fiber prepreg, comprising a machine table 10 and a machine body 20. There is a feeding chute 21 provided between the machine table 10 and the machine body 20. A conveyor belt 40 is installed on the machine table 10 in the area of the feeding chute 21. A driving motor 60 is installed on one side of the conveyor belt 40. A plurality of ultra-high frequency electromagnetic wave generators 30 are installed on the inner top of the machine body 20;

[0024] An extension mechanism 50 is installed in the area of the conveyor belt 40. The extension mechanism 50 includes two coupling shafts 51 installed on both sides of one end of the conveyor belt 40, and a plurality of extension wheels 55 installed obliquely at equal distances on both sides of the top of the conveyor belt 40. One of the coupling shafts 51 is connected to the driving motor 60. First gears 52 are installed on both of the two coupling shafts 51. Transmission shafts 56 are installed at the outer ends of the plurality of extension wheels 55. Transmission wheels 57 are installed on the transmission shafts 56. Transmission belts 58 are sleeved on the transmission wheels 57 on adjacent pairs of the transmission shafts 56. A third gear 54 is installed on the transmission shaft 56 of the transmission wheel 57 close to the first gear 52. A second gear 53 is installed between the first gear 52 and the third gear 54. The first gear 52, the second gear 53 and the third gear 54 are meshed with each other.

[0025] In addition, it should be noted that the electrical components of this device are all electrically connected to a conventional PLC controller.

[0026] Specifically, please refer to the appendix Figure 2 On both sides of the second gear 53, there are vertical rods rotatably connected, and the vertical rods are fixedly connected to the inside of the machine table 10;

[0027] In this embodiment, it should be noted that the position of the second gear 53 is fixed and can continuously mesh with the first gear 52.

[0028] Specifically, please refer to the appendix Figure 2 The tooth number ratio of the first gear 52, the second gear 53, and the third gear 54 is 1:1:1;

[0029] In this embodiment, it should be noted that the transmission ratios between the first gear 52, the second gear 53, and the third gear 54 are the same, which can ensure that the movement speeds of the conveyor belt 40 and the extension wheel 55 are the same, so that the composite material will not be overextended.

[0030] Specifically, please refer to the appendix Figure 2 The included angle between the extension wheel 55 and the conveyor belt 40 in the width direction is 30°;

[0031] In this embodiment, it should be noted that when the extension wheel 55 rotates, the composite material can be extended outwards when being transported on the conveyor belt 40, and the 30° inclination angle can prevent overextension and ensure that part of the extension wheel 55 acts in the advancing direction of the composite material.

[0032] Specifically, please refer to the appendix Figure 3 Inside the machine table 10, there is also a lifting mechanism 70 installed. The lifting mechanism 70 includes a cylinder 71 installed inside the machine table 10 and a U-shaped frame 72 installed on the top of the cylinder 71. On both sides of the top of the U-shaped frame 72, there are cross plates 73 installed, and the multiple rotating shafts 56 are respectively rotatably connected to the corresponding cross plates 73;

[0033] In this embodiment, it should be noted that when installing the composite material on the conveyor belt 40, the composite material needs to pass through the feeding slot 21. At this time, the cylinder 71 can be started to make the multiple extension wheels 55, rotating shafts 56, transmission wheels 57, transmission belts 58, and third gears 54 of the extension mechanism 50 move upwards, exposing the gap between the extension wheels 55 and the conveyor belt 40, which is convenient for placing the composite material on the conveyor belt 40. After installation, the cylinder 71 can be lowered to make the extension wheels 55 contact the composite material;

[0034] In addition, it should be noted that the cross plate 73 on one side in the appendix Figure 2 is shortened for better showing the structure at the gear position, and the rotating shaft 56 where the third gear 54 is located is also rotatably connected to the cross plate 73.

[0035] Furthermore, the center of the first gear 52 is located on the axis of the coupling shaft 51;

[0036] In this embodiment, it should be noted that when the connecting shaft 51 rotates, the oblique first gear 52 will not be in an eccentric state, thereby affecting the transmission with other gears.

[0037] The specific operation mode of the utility model is as follows:

[0038] First, the composite material is passed through the feed slot 21 and laid on the conveyor belt 40, and then the cylinder 71 is lowered to make the extension wheel 55 contact with the composite material. Subsequently, the drive motor 60 is operated to rotate the connecting shaft 51, and then the first gear 52, the second gear 53, and the third gear 54 are engaged and transmitted to realize the synchronous rotation of the first extension wheel 55. At the same time, through the transmission of multiple transmission wheels 57 and the transmission belt 58, the synchronous and unidirectional rotation of multiple extension wheels 55 can be realized. During the transportation process, the composite material will contact the oblique extension wheel 55 and generate an oblique force. The force is split into two directions, one in the conveying direction and the other in the extension direction on both sides, to ensure that the composite material is stretched without causing excessive stretching. Finally, the ultra-high frequency electromagnetic wave generator 30 emits electromagnetic waves to heat the composite material to complete the carbon fiber impregnation process.

[0039] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
