Overall stroke adjustment device for heald motors

technical field

The invention relates to a total stroke adjustment device for a heald motor.

Background technique

At present, before each loom weaves, about 8000-15000 raw warp fibers need to pass through each heald on the loom according to a certain rule, and then pass through the beat-up steel according to another rule. Each reed seam on the reed cannot be threaded wrongly. The driving force of the heald wire in the existing automatic heald threading equipment mainly comes from the heald wire motor. However, due to the different lengths of the heald wire, the heald wire motor needs to be adjusted. The relative height, on the other hand, since the heald motor is running under load, the position stability during its operation needs to be considered. How to realize a device for controlling the position and stability of the heald motor suitable for the heald automation equipment is the object of research by those skilled in the art.

The invention provides an overall stroke adjusting device for a heald motor with simple structure, controllable position and stable operation.

A total stroke adjustment device for a heald motor, the total stroke adjustment device comprises an elongated total stroke seat, a first nut and a second nut are respectively connected inside the total stroke seat, the first nut and the second The nuts are respectively connected with the first screw rod and the second screw rod, the tops of the first screw rod and the second screw rod are respectively connected with a first rapid ratchet wrench and a second rapid ratchet wrench, the first screw rod and the second screw rod are connected with the first rapid ratchet wrench and the second There is a top cover between the quick ratchet wrenches. The side of the top cover is connected to the sliding guide rail installed on the side of the total travel seat. A connecting seat is installed on the sliding guide rail. The connecting seat drives the driving wheel through the heald motor, and the driving wheel is driven by the belt. The driven wheel is connected with a spline shaft, which is mainly used to improve the stability of the output torque. The overall adjustment device combines the position of the heald motor with the overall seat. Since the overall seat is the girder of the entire heald automation equipment, its position is relatively stable, and serves as a basic stability as a connecting part of the heald motor. The first screw rod and the second screw rod cooperate with the first nut and the second nut to realize the up and down movement ability of the top cover under the driving of the first quick ratchet wrench and the second quick ratchet wrench. The motor has the performance of up and down movement, and the control mode of the two screws can realize the reverse locking performance of the axial direction.

The top cover is internally connected with a tensioning block that matches the first screw, and the tensioning block is provided with two screw holes, and the radial locking performance after the first screw is adjusted in place is realized by the two screws being matched one after the other. .

The side of the sliding guide rail is provided with a tension adjusting guide rail installed on the total travel seat. The tension adjusting guide rail is an accessory accessory in the present invention, which is mainly used to cooperate with the needle hanging belt on the heald equipment to extend the hanging force. The service life of the needle belt.

The top cover is internally connected with a sensor installed on the sensor base, and the main function of the sensor is to determine the rotational position of the first screw, and indirectly achieve the technical purpose of accurately controlling the position of the heald motor.

The side of the general seat is provided with a grounding spring to prevent the equipment from conducting electricity to improve the safety of the equipment, and the grounding spring can be connected to the grounding wire.

The length of the first screw is longer than that of the second screw, the height of the two screws with different lengths is mainly adjusted by the first screw, and the second screw controls the locking force.

The present invention adopts the first screw rod and the second screw rod to cooperate with the first nut and the second nut to realize the up and down movement ability of the top cover driven by the first quick ratchet wrench and the second quick ratchet wrench. The heald motor has the performance of up and down movement, so as to achieve the technical purpose of precise adjustment of the position of the heald motor.
