[0031] like Figures 1 to 4 As shown, the present embodiment provides a traction device for UD cloth, including three driven rollers 3 arranged horizontally and spaced apart on a frame 1, a driving roller 4 arranged at intervals just above the driven roller 3, and a UD cloth placed between the driven roller 3 and the driving roller 4; the driven roller 3 and the driving roller 4 have the same diameter, which is 300-350 mm, and the driving roller 4 is arranged vertically with the driven roller 3, and the centers are vertically aligned. The driving roller and the driven roller with the same diameter and vertically aligned centers rotate in unison, and the traction force on the UD cloth is uniform, the tension and conveying effect are good, and the UD cloth has good flatness and high quality.

[0032] In this embodiment, one end of the active roller 4 is rotatably connected to the reducer 5, and a servo motor 6 is arranged on the top of the reducer 5, and the servo motor 6 drives the reducer 5 to rotate. The three servo motors 6 have the same speed when working; the power is the same, all of which are 50W. Compared with the 40 kilowatts of the existing equipment, the operating energy consumption of the equipment is greatly reduced. The three servo motors 6 drive the reducer 5 to rotate respectively, and the reducer 5 increases the torque driving the active roller 4, which can then drive the active roller 4 to rotate. The overall structure of the equipment is simple and the volume is small, which realizes the traction of the UD cloth by the low-power servo motor, greatly reducing the operating energy consumption of the equipment, and thus reducing the production cost.

[0033] In this embodiment, three groups of circular fixing frames 31 are symmetrically arranged on the frame 1, and the bearing seats 32 are fixed in the circular fixing frames 31. The bearing seats 32 are rotatably connected to the roller shafts at both ends of the driven roller 3. The driven roller 3 is a hollow structure, and heating oil is arranged in the hollow cavity; the roller shaft at one end of the driven roller 3 is a through-tube structure, one end of the roller shaft is connected to the hollow cavity of the driven roller 3, and the other end of the roller shaft is rotatably connected to the joint assembly 33; the joint assembly 33 is provided with an oil inlet 331 and an oil outlet 332, and the oil inlet 331 and the oil outlet 332 are respectively connected to one end of the oil pipe 333, and the other end of the oil pipe 333 is connected to the oil mold machine 2. The oil mold machine 2 controls the heating oil in the hollow cavity of the driven roller 3 to be 90 degrees Celsius. The oil mold machine 2 realizes the circulation heating of the heating oil in the hollow cavity of the driven roller 3 through the oil inlet 331 and the oil outlet 332, so that it is kept at 90 degrees Celsius, and the heating is uniform at 90 degrees Celsius, and the UD cloth heating molding effect is good.

[0034] In this embodiment, an adjustable bearing seat 41 is arranged on the top surface of the return-shaped fixing frame 31. The adjustable bearing seat 41 rotates the roller shaft connected to the active roller 4. The adjustable bearing seat 41 is used to adjust the distance between the active roller 4 and the driven roller 3. The distance between the active roller 4 and the driven roller 3 is 0.5mm to 3mm. A support plate 42 is arranged on the side of the return-shaped fixing frame 31. A reducer 5 is arranged on the support plate 42. Bolts are arranged through the support plate 42 from the bottom, and the top of the bolts abuts against the bottom of the reducer 5. The adjustable bearing seat 41 can adjust the distance between the active roller 4 and the driven roller 3 to adapt to UD cloths of different thicknesses. The hand wheel of the adjustable bearing seat 41 is rotated to drive the active roller 4 to move upward or downward, thereby adjusting the distance between the active roller 4 and the driven roller 3. After adjusting the appropriate distance, the bolts arranged through the support plate 42 from the bottom are rotated so that the top of the bolts abuts against the bottom of the reducer 5, which is used to position and support the bottom of the reducer 5.
