Yarn twining method and yarn twining device for carbon fiber baseball

Abstract

The invention discloses a yarn twining method and a yarn twining device for a carbon fiber baseball. The yarn twining device comprises a workbench provided with a screw rod, a coiled yarn stand and a support frame for clamping and fixing a baseball core shaft; the coiled yarn stand and the support frame are both arranged on the workbench; as the baseball core shaft is fixed on the yarn twining device, coiled yarn moves left and right along the core shaft for continuous twining yarn so as to reduce labor power and time and improve production efficiency; a chuck is driven to rotate by a motor, rotate speed is uniform and stable, and force and gaps for twining the yarn are uniform, so that a defect that the yarn is not twined flat in the prior art is overcome, accordingly rigidity and strength of finished product can be better ensured, not only is rejection rate reduced, a carbon fiber layer of the product is flat, wall thickness is uniform and the product does not deform, but also product size can be effectively controlled.

Description

technical field [0001] The invention relates to a method for making a carbon fiber baseball, in particular to a method for covering a mandrel of a baseball with carbon fiber yarn and special equipment for covering the yarn. Background technique [0002] Due to the high cost of carbon fiber materials, the carbon fiber products made of them are basically shells. During production, multi-layer carbon fiber cloth is wrapped on the body that is consistent with the shape of the product and slightly smaller than the product size to make a semi-finished product, and then put it Inflate, pressurize, and heat the mold to solidify the carbon fiber layer, then take out the green body and process it to obtain a carbon fiber product; in order to increase the strength of the carbon fiber product, the textures of adjacent carbon fiber cloths must be staggered at a certain angle when making carbon fiber products , layer by layer to achieve the required thickness and strength of the product. ...

AI Technical Summary

Problems solved by technology

In this way, it takes a long time to wrap the carbon fiber layer, and the workload is heavy, and the workers need to stand for a long time during operation, which not only has low production efficiency, but also has a high labor intensity for the workers; because the force used for manual winding is unstable each time, the winding distance Unevenness, resulting in uneven wall thickness and carbon yarn texture of the formed product, so that the strength and rigidity of the product cannot be well guaranteed. Even if the baseball player uses the same strength, the effect of hitting the ball with different strokes is not the same. , cannot be controlled, resulting in the user not being able to perform well

[0004] From the above description, it can be seen that the coating of the carbon fiber layer alone needs to be coated for a long time. Quality: In order to meet the width, length and texture requirements of the product, fiber cloth is constantly cut, resulting in a large waste of materials, and because carbon fiber cloth cannot be recycled, in order to reduce costs and reduce the impact on the environment, the utilization rate of materials needs to be improved
