Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a carbon fiber unwinding frame with adjustable tension. Background Art

[0002] Carbon fiber woven fabric is the basic element of carbon fiber composite materials. In various fields of carbon fiber application, various prefabricated parts with carbon fiber fabric as reinforcement are the main form of carbon fiber products.

[0003] Conventional control of carbon fiber unwinding tension is done by setting a friction disk on the bobbin seat, then winding a belt around the friction disk, with one end of the belt fixed and the other end connected to an elastic device such as a spring, and then adjusting the tension of the spring to change the friction between the belt and the friction disk to control the tension of the bobbin when unwinding. This control method is difficult to control due to the consistent tension of the spring, and the tension data cannot be visualized. The tension of the bobbin when unwinding is adjusted entirely by feeling and observation. Utility Model Content

[0004] The utility model provides a carbon fiber unwinding creel with adjustable tension, which is used to overcome the defects in the prior art that the carbon fiber unwinding tension is difficult to control and the tension data is not intuitive.

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

[0006] The utility model discloses a carbon fiber unwinding yarn frame with adjustable tension, comprising a yarn frame outer frame, on which a plurality of constant tension yarn tube seats are evenly distributed, each of which has a yarn guide rod on its upper side, one side of the constant tension yarn tube seat is sleeved with a carbon fiber yarn tube, and the other side is equipped with a torque motor for realizing individual adjustment of the tension of the carbon fiber yarn tube.

[0007] Furthermore, the carbon fiber yarn tube is sleeved on one side of the constant tension yarn tube seat through a yarn tube support, and the torque motor is installed on the other side of the constant tension yarn tube seat through a motor seat.

[0008] Furthermore, the output end of the torque motor is connected to one end of the yarn bobbin support through a coupling installed in the motor seat, and a bearing is sleeved on the yarn bobbin support.

[0009] Furthermore, rollers are installed at the bottom of the outer frame of the creel for easy movement.

[0010] Furthermore, anchor screws are provided beside the rollers, which are used to adjust the level of the outer frame of the creel and provide auxiliary support.

[0011] Furthermore, the outer frame of the yarn rack is electrically connected to a control cabinet, and a screen of the control cabinet is used to display the tension reading of each carbon fiber yarn tube.

[0012] The beneficial effect achieved by the utility model is that each constant tension yarn drum seat is controlled by an independent torque motor, so the tension of each carbon fiber yarn drum can be adjusted individually, ensuring that each carbon fiber yarn drum does not interfere with each other when the yarn is discharged through the yarn guide rod, and the corresponding tension reading of each carbon fiber yarn drum is displayed on the screen of the control cabinet.
