Cloth clamping adjusting device of cloth pulling machine

Abstract

The invention discloses a cloth clamping adjusting device of a cloth pulling machine. The cloth clamping adjusting device comprises a lower cloth pressing roll shaft, an upper cloth pressing roll shaft, cloth pressing side plates, a driving mechanism and upper machine plates. The two ends of the lower cloth pressing roll shaft are installed on the upper machine plates on the corresponding sides. The two ends of the upper cloth pressing roll shaft are installed on the cloth pressing side plates on the corresponding sides. Two electric push rods are arranged at the positions close to the corresponding cloth pressing side plates and can push the two cloth pressing side plates to rotate synchronously. The upper cloth pressing roll shaft is close to or away from the lower cloth pressing roll shaft under the drive of the cloth pressing side plates, and then the cloth clamping gap between the upper cloth pressing roll shaft and the lower cloth pressing roll shaft is adjusted. The cloth clamping adjusting device of the cloth pulling machine has the advantages that the two cloth pressing side plates can be pushed by the two electric push rods to rotate synchronously, the cloth pressing side plates drive the upper cloth pressing roll shaft to move relative to the lower cloth pressing roll shaft, and therefore the cloth clamping gap is adjusted; and meanwhile, due to the fact that the two electric push rods act synchronously during adjustment, the cloth clamping gap can be adjusted with higher precision, it is ensured that the width of the whole gap is uniform, and then the cloth clamping effect is improved.

Description

technical field [0001] The invention relates to a cloth spreading machine, in particular to a cloth clamping adjustment device of the cloth spreading machine. Background technique [0002] Cloth stretching machine is an important cloth spreading and stacking tool in the garment production industry. It can save a lot of manpower. It is mainly used for stretching and cutting cloth, so that the whole roll of cloth can be pulled out to an appropriate length, and then cut and cut. It becomes a fabric with an appropriate size, and can achieve automatic feeding and automatic edge alignment. [0003] Since a cloth stretching machine needs to be suitable for cloths of different thicknesses, a cloth clamp adjustment device is installed on the cloth stretcher, and the cloth clamp adjustment device is used to adjust the gap between the lower cloth pressing roller shaft and the upper cloth pressing roller shaft , to ensure that the cloth clamping device has sufficient clamping force on ...

AI Technical Summary

Problems solved by technology

The existing cloth clamping adjustment device is mainly realized by manual adjustment, such as adjusting the position of the upper pressing roller shaft by adjusting bolts. Generally, there are two adjusting bolts and they are respectively arranged at positions close to the two ends of the upper pressing roller shaft. , it is necessary to adjust the two adjusting bolts, and the adjustment is troublesome. Moreover, due to the low adjustment accuracy of manual adjustment, not only is it not easy to adjust the gap to the size required for cloth clamping, but it is also easy to cause the upper pressure roller shaft There is a difference in height at both ends, resulting in inconsistent dimensions at both ends of the gap, which adversely affects the clamping cloth
