Description

Technical Field

[0001] The utility model relates to a carbon fiber winding mechanism, in particular to a constant tension carbon fiber winding mechanism. Background Art

[0002] In the process of processing and reproducing carbon fiber, the rolled carbon fiber filaments need to be unwound, spread out, collected and then used in production. Carbon fiber winding is a very important process, and its quality and efficiency have a vital impact on the operation of the entire production line.

[0003] Conventional control of winding tension is through a tension swing shaft structure, with a swing arm set on the swing shaft, a yarn guide roller installed at one end of the swing arm, a spring-type tension device installed at the other end, and then a tension sensor installed at the end to control the tension. The disadvantage of this method is that the tension adjustment range of the spring is limited, and the response sensitivity is not enough. Utility Model Content

[0004] The utility model provides a constant tension carbon fiber winding mechanism for overcoming the defects of poor tension adjustment range and insufficient sensitivity of the winding mechanism in the prior art.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a constant tension carbon fiber winding mechanism, comprising a frame, one end of a tension swing arm is installed on the upper end of the frame through a tension swing arm rotating shaft, the other end is provided with a yarn guide roller, the lower end of the frame is provided with a winding device, the winding device is located below the yarn guide roller, and the carbon fiber yarn sheet is wound up by the winding device after passing through the yarn guide roller.

[0007] Furthermore, one end of the tension swing arm shaft is connected to the output end of the planetary reducer servo motor, and the other end is installed with an angle sensor.

[0008] Furthermore, one end of the winding device is connected to a winding motor as a power element.

[0009] Furthermore, the tension swing arm swings up and down as the tension of the carbon fiber yarn sheet changes.

[0010] Furthermore, the winding device comprises a winding shaft, on which a winding drum head is arranged, and both ends of the winding drum head are provided with baffles for limiting the position of the carbon fiber yarn sheet.

[0011] The beneficial effect achieved by the utility model is that the planetary reducer servo motor and the angle sensor are coaxially installed at the two ends of the tension swing arm shaft respectively, and the carbon fiber yarn sheet will generate tension when passing through the yarn guide roller and being wound up by the winding mechanism. When the tension changes, the signal of the rotation of the tension swing arm shaft will be received by the angle sensor, and then a command will be sent to the servo motor, and the servo motor will actively adjust the torque to achieve the purpose of constant tension. At the same time, the servo motor can be arbitrarily set according to the tension required for carbon fiber yarn sheets of different specifications when winding. BRIEF DESCRIPTION OF THE DRAWINGS
