Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery, and in particular relates to a single / double-drive plug-in needle type belt transmission sley. Background Art

[0002] The main components of the sley are the screw nut drive mechanism in the cavity of the sley profile, the reed hinge attached to the outside of the profile, and the multi-toothed reed blade installed on the reed hinge. The defects of the existing reed blades and reed chains are as follows: the reed blade is a welded body of multiple reed needles and a reed blade bottom plate, but when a reed needle fails due to rust or other reasons, the entire reed blade needs to be replaced. The reed blade is installed on the reed hinge, not the reed needles are hinged to each other, and the distance between the reed needles at the transition of the two reed blades cannot be consistent with the distance between the reed needles on the same reed blade. The distance between the reed needles is very narrow, and it is very difficult to arrange the reed needles evenly on the reed blade bottom plate and weld them together, and the manufacturing cycle is long. The arrangement of the reed needles is often set to periodic helical teeth according to production needs. Because the number of helical teeth required by each user is different, it is difficult to pre-manufacture a large number of reed blades.

[0003] In addition, the existing mechanism has a major defect, that is, in the textile environment, the flying flowers enter the inside of the sley and entangle the screw rod, thereby blocking the thread pair. Secondly, there is no device inside the sley to prevent the nut from reaching the limit position. When it is blocked and stuck at the limit position, the screw rod and the screw are screwed and it is difficult to reversely loosen them, so that the reed chain cannot be extended or retracted.

[0004] Therefore, it is necessary to develop a single / double-drive plug-in needle belt transmission sley in order to solve the above-mentioned technical problems. Summary of the invention

Since the second transmission device is meshed with the first transmission device's gear complex through the gear complex, the second transmission device moves relative to the first transmission device. This causes the reed chain to shrink. The internal position check switch controls the limit of the first drive movement. When the limit position is exceeded, the control circuit is cut off, so that the motor no longer runs.
