Griffe transmission mechanism of electronic jacquard machine

Abstract

The invention discloses a griffe transmission mechanism of an electronic jacquard machine. The griffe transmission mechanism comprises a griffe on the lower end of a frame, a plurality of needle lifting arms on two sides of the frame for lifting the griffe, a plurality of links for connecting the needle lifting arms, and a transmission spindle installed by means of fixing plates at two sides of the upper end of the frame, wherein the transmission spindle is provided with driving chain wheels on the inner sides of the fixing plates; the outer sides of the fixing plates are provided with driving gears; the driving chain wheels are connected with eccentric driven chain wheels by chains; the driving gears are engaged with eccentric gears; and the outer sides of the fixing plates are provided with outer side cranks coaxial with the eccentric driven chain wheels while the inner sides of the fixing plates are provided with inner side cranks coaxial with the eccentric gears. According to the griffe transmission mechanism of the electronic jacquard machine in the invention, one transmission spindle is used to drive the eccentric driven chain wheels and the eccentric gears at two sides of the frame as well as the outer side cranks and the inner side cranks to stagger by 180 degrees in order to lift or drop four needle lifting arms connected with a loom, and to drive the griffe to synchronously lift jacquard needles to sequentially move upwards to form a scissors-like warp thread opening; and the whole transmission mechanism is simple in structure, skilful in design and smooth in operation.

Description

Technical field [0001] The invention relates to mechanical components of an electronic jacquard machine, and in particular to a power transmission mechanism for lifting a knife in an electronic jacquard machine. Background technique [0002] In the field of textiles, fabrics are usually woven with warp and weft threads. On the loom, it is necessary to divide the warp threads into upper and lower layers according to certain rules and alternately form a channel for the weft threads to pass through, that is, an opening. After the weft threads are introduced into the opening, the two layers of warp threads alternate up and down according to the fabric weave method to form a new weft thread. Open the opening and repeat this to complete the weaving process of the fabric. The warp formation of the warp opening is completed by the warp opening selection structure, which is the core step in textile technology. The warp opening selection structure must adapt to the needs of modern t...
