[0017] The following is a specific embodiment of the utility model and is combined with the drawings to further describe the technical scheme of the utility model, but the utility model is not limited to these embodiments.

[0018] Embodiment 1

[0019] As Figure 1 The utility model discloses a adjustable tension polyimide unidirectional prepreg warping device, including support frame 1, a plurality of reed 2, a plurality of disc head 3 and a plurality of driving part 4, a plurality of reed 2 all are through the optical axis 5 interval and are erected on support frame 1, a plurality of disc head 3 rotatable setting is in support frame 1, and is located below reed 2, a plurality of driving part 4 one one corresponds with disc head 3 drive connection, to drive disc head 3 with certain rate rotation, yarn is wound on disc head 3, and one end of yarn is drawn through the optical axis 5, passes through reed 2.

[0020] The utility model discloses a polyimide yarn is wound on disc head 3, and the rotating speed of disc head 3 is controlled through driving part 4, and then the unwinding tension of polyimide yarn is changed.

[0021] The utility model discloses not only can satisfy the demand of more total warp number of polyimide unidirectional prepreg, but also guarantees that yarn arrangement is neat, density is uniform and tension is evenly entered into release paper.

[0022] The device of this invention can also be used in other processes that require adjustment of yarn unwinding tension. It has a wide range of applications, high practicality, and is easy to operate.

[0023] Example 2

[0024] like Figure 1 As shown, the two ends of the optical shaft 5 are rotatably mounted on the support frame 1, and the reed 2 is fixed obliquely on the optical shaft 5. The rotatable mounting of the two ends of the optical shaft 5 on the support frame 1 reduces friction between the optical shaft 5 and the yarn, thus minimizing damage to the yarn, as one end of the yarn passes through the optical shaft 5 and then through the reed 2.

[0025] There are several ways in which the two ends of the optical axis 5 can be rotatably mounted on the support frame 1. For example, the two ends of the optical axis 5 are provided with bearing seats (not shown in the figure), the bearing seats are fixed on the support frame 1, and the two ends of the optical axis 5 can rotate relative to the bearing seats. The angle between the reed 2 and the horizontal plane containing the axis of the optical axis 5 can be 30-60°. Preferably, the angle can be 45°.

The output end of the servo motor 41 is connected to the other end of the head 3 via a coupling 6. The rotation speed of the head 3 is controlled by controlling the power of the servo motor 41, thereby changing the unwinding tension of the yarn.

[0029] The bottom of the support frame 1 is fixedly equipped with multiple casters 7, which not only facilitates the movement of the machine, but also provides better braking effect to resist the traction force of the polyimide yarn.
