Description

Technical Field

[0002] In textile machinery, the drawing frame uses rollers and leather rollers to combine and stretch the dispersed cotton strips, which improves the uniformity of the cotton strips and the straightness and parallelism of the fibers, and makes the fibers of different qualities mixed more evenly in the cotton strips. The adjustment of the leather roller spacing can reduce the occurrence of uneven drafting and reduce the fluctuation of spinning quality. In order to better control the movement of fibers, the adjustment of the leather roller spacing is an indispensable condition for reasonable drafting.

[0003] The utility model with application number CN201920417907.6 discloses a drawing frame roller spacing adjustment device. The motor drives the screw rod to rotate, so that the nut and the transverse plate move horizontally, thereby pushing the roller to move horizontally.

[0004] The above device drives the transverse plate to move by rotating the lead screw driven by a motor, and can only move one leather roller transversely. However, in the drawing machine, the number of leather rollers is generally three to four, and all the leather rollers are driven to move by one lead screw. The leather rollers move together and the gauge cannot be adjusted. The gauge is always fixed, the adjustment effect is poor, and it cannot be adjusted in time.
