Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber plate production equipment, in particular to a production device for low-deformation carbon fiber plates. Background Art

[0002] At present, there is a disadvantage in the components processed by carbon fiber plates, that is, the deformation is large when subjected to stress, and the tensile elongation at break can reach more than 5%. Analysis of the reasons shows that the large deformation of carbon fiber plates is mainly due to the fact that the carbon fiber is not fully stretched during the production of carbon fiber plates, causing the carbon fiber to bend in the axial direction. When subjected to tension, the fiber cannot be fully straightened to bear the load, and it needs to go through a tensile deformation stage before it can be fully straightened to bear the load.

[0003] Publication No. CN 213767262 U proposes a production and manufacturing device for low-deformation carbon fiber plates, comprising a mold table, wherein first drafting rollers are provided on both upper and lower sides of the mold table, and second drafting rollers are provided on both left and right sides of the mold table. Bearings are fixedly mounted on the surfaces of both sides of each first drafting roller and each second drafting roller, and each bearing surface has a through hole in the middle position, each through hole has a nut inside, and each nut has a threaded rod inside. During use, due to the lack of a side limiting mechanism, prepreg fiber materials of different sizes may deviate to the side during the pulling process, resulting in the material not being effectively stretched, thereby affecting the processing effect and accuracy of the equipment. To this end, we propose a production device for low-deformation carbon fiber plates. Utility Model Content

[0019] A limiting mechanism consisting of a limiting disk 12 and a movable ring 13 is provided on both the first roller 11 and the second roller 23. The position of the limiting mechanism can be easily adjusted under the action of the limiting screw 14. The limiting mechanism can prevent the material from shifting to the side during traction, further ensuring the molding effect of the carbon fiber plate.

[0020] In the above solution, grooves 15 are formed on the sides of the first roller 11 and the second roller 23 , and the grooves 15 are connected to the clamping plates 17 via springs 16 .

[0021] By arranging the spring 16 and the clamping plate 17 structure in the groove 15, the material can be clamped and fixed quickly, which is simple and convenient to use. The elasticity of the spring 16 makes the two groups of clamping plates 17 approach each other and thus clamp the ends of the material.

[0022] In the above embodiment, threaded holes 18 and guide holes 19 are correspondingly formed on the first roller 11 and the second roller 23. These threaded holes 18 and guide holes 19 on the first roller 11 and the second roller 23 are used in conjunction with the first bidirectional screw rod 2, the first guide rod 21, the second bidirectional screw rod 24, and the second guide rod 25, respectively. The second bidirectional screw rod 24 is threadedly connected to the threaded hole 18 of the second roller 23.

[0025] In the above solution, the first roller 11 and the second roller 23 are arranged vertically.

Covering the top of the base 1 during processing can form a protective effect to prevent external impurities from entering the inner cavity of the base 1 and causing contamination, thereby effectively improving the processing quality.

[0027] Working principle:

[0028] When this low-deformation carbon fiber board production device is used, the two ends of the lower layer of prepreg fiber material are correspondingly clamped in the grooves 15 on the side of the first roller 11, and the elasticity of the spring 16 makes the two sets of clamping plates 17 approach each other to clamp the ends of the material. Then, the first motor 22 is started to drive the first bidirectional screw 2 to rotate, and the spacing between the two first rollers 11 is adjusted under its action. The material is tensioned by the cooperation of the two first rollers 11. Then, the two ends of the upper layer of prepreg fiber material are correspondingly clamped in the grooves 15 on the side of the second roller 23, and the above positioning process is repeated. The second motor 26 is started to adjust the spacing between the two second rollers 23 to tension the material so that the material can be effectively stretched. Under the action of the limiting screw 14, the position of the limiting mechanism can be conveniently adjusted so that the limiting plate 12 is correspondingly abutted against the side of the material from the outside. The limiting mechanism can prevent the material from deviating to the side during traction, thereby further ensuring the molding effect of the carbon fiber board.
