Electromagnetic transmission mechanism of electronic jacquard machine

Abstract

The invention discloses an electromagnetic transmission mechanism of an electronic jacquard machine. The electromagnetic transmission mechanism comprises a permanent magnet stator, a coil rotor assembly, a broach frame plate, a small pull rod component, a broach blade, a rack and an anti-abrasion roller, wherein the upper end of the permanent magnet stator and the rack form a revolute pair, and arevolute pair is formed between a connecting piece on the coil rotor assembly and the broach frame plate through a rolling bearing; the broach frame plate and the small pull rod component form a revolute pair through a rolling bearing; a revolute pair is formed between the small pull rod component and the broach blade through an anti-abrasion shaft sleeve; the broach blade and another mechanism assembly box of the electronic jacquard machine form a sliding pair to limit the displacement of the broach blade in the horizontal direction; and the anti-abrasion roller is installed on the connectingpiece of the coil rotor assembly on the right side, and the anti-abrasion roller and the rack form a sliding pair to limit the displacement of the coil rotor assembly on the right side in the horizontal direction. According to the invention, the transmission efficiency of the transmission mechanism of the jacquard machine is greatly improved, abrasion between parts is reduced, the energy utilization rate is increased, and meanwhile maintenance becomes easier and more convenient.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to an opening movement mechanism, in particular to an electromagnetic transmission mechanism of an electronic jacquard machine. Background technique [0002] The connecting rod type shedding mechanism is a mechanism composed of many rigid rods connected by low pairs. Its function is to complete the shedding of the warp yarns. At the same time, it also controls the lifting sequence of the heald frames according to the sequence set in the machine diagram on the fabric, so that the fabric can obtain required organizational structure. [0003] In the preparation process before weaving, the warp yarns are threaded into the heddle eyes of the heddles according to the order of the heald drawing, and sent to the loom together with the heald frame reed, etc. It is divided into upper and lower layers to form a channel through which the shuttle or weft insertion device and the weft ...
