Description

A loom transmission mechanism based on variable speed motor

technical field

The invention relates to the technical field of textile machinery, in particular to a loom transmission mechanism based on a variable speed motor.

Background technique

The loom generally includes a weft insertion mechanism and a beating-up mechanism. The loom is disengaged after the weft yarn is broken. Since the transmission mechanism is still rotating, a section of the weft yarn will not be woven, which needs to be reversed through the transmission mechanism. Weaving is carried out after the weft is introduced.

2 is a schematic diagram of the transmission mechanism of the loom in the prior art, including a common three-phase motor 10, a small pulley 11, a V-belt 12, a large pulley 13, a main clutch 14, a small gear 15, a large gear 16, and a ring gear 17 , main drive shaft 18, intermediate wheel 19, output gear 20, output shaft 21, reversing clutch 22, reversing large gear 23, reversing device 24; wherein, the output shaft 21 is connected with the output gear 20, and the output end of the reversing device 24 is connected to the reversing The large gear 23 is meshed and connected, and the reversing clutch 22 is connected with the large reversing gear 23 . During its working process, the three-phase motor 10 drives the large pulley 13 to rotate through the V-belt 12, and connects the large gear 16 with the pinion 15 through the main clutch 14, and the pinion 15 drives the large gear 16 to drive the main drive shaft 18 to rotate. , and drive the output gear 20 to rotate in turn through the ring gear 17 and the intermediate wheel 19; if the weft yarn breaks during the weaving process, the reversing gear 23 needs to be controlled by the reversing device 24 to rotate, so that the reversing clutch 22 is connected with the output gear 20, and then passes through The cooperation of the three-phase motor 10 completes the reversing, and then the weft yarn is introduced to continue weaving. The disadvantages are: (1) There are many types of parts, many installation and production processes, and high manufacturing costs; (2) The transmission mechanism is complex, resulting in many transmission steps, many reversing steps, and low work efficiency; (3) In the process of finding the weft , It is necessary to adjust the speed and reverse the car at a slow speed, but the reversing device and the ordinary three-phase motor cannot change the speed, and can not achieve stable slow-speed reversing.
