Computer jacquard machine and transmission mechanism thereof

Abstract

The invention discloses a computer jacquard machine and a transmission mechanism thereof. The transmission mechanism comprises a main shaft and two sets of jacquard driving devices driven by the main shaft, wherein each jacquard driving device comprises an upper shaft and a lower shaft; a first oscillating bar, an upper fixing base and a second oscillating bar are successively sleeved and fixed on the upper shaft; the first and the second oscillating bars are arranged between inner and outer side plates of a stand and respectively fixed at the two sides of the upper fixing base; a third oscillating bar, an upper fixing base and a fourth oscillating bar are successively sleeved and fixed on the lower shaft; the third and fourth oscillating bars are arranged between the inner and outer side plates and respectively fixed at the two sides of the lower fixing base. According to the computer jacquard machine and the transmission mechanism thereof, the design form that the upper shaft and the lower shaft penetrate through is changed, the upper and lower jacquard devices are respectively driven by the left and right sets of jacquard driving devices, and barriers of the upper shaft and the lower shaft do not exist in the middle of the stand, so that the faulted upper and lower jacquard devices can be maintained conveniently without dismounting the upper shaft and the lower shaft; besides, the lengths of the upper shaft and the lower shaft are shortened, so that noise is further lowered.

Description

technical field [0001] The invention relates to a computerized jacquard machine, in particular to a computerized jacquard machine and its transmission mechanism. Background technique [0002] Electronic jacquard technology breaks through the limitation of the number of needles of traditional mechanical jacquard, which makes the fabric pattern more complicated, and the restriction on the number of products (batches) can be smaller, which can meet the needs of multiple varieties, small batches and individualization of textiles, thus Substantially increase the grade of textiles and the added value of products. From past experience, we know that the stability of the computerized jacquard machine is extremely important. If the jacquard machine has an accidental wrong action, it may lead to defects or even scrapping of textile products. [0003] When the knife lifting device in the existing computer jacquard machine lifts up the warp yarns under the drive of the transmission mech...
