Novel jacquard shedding device

Abstract

The invention discloses a novel jacquard shedding device, and belongs to the field of textile machinery. The novel jacquard shedding device structurally comprises a cam mechanism, a swing arm mechanism, a lifting plate mechanism and a box mechanism, and is characterized in that the cam mechanism is mounted in the box mechanism, the cam mechanism is fixedly connected with the swing arm mechanism, and the lifting plate mechanism is fixedly connected with the swing arm mechanism. The novel jacquard shedding device has the advantages of high stability, high precision, wider adaptability, light transmission, low energy consumption, simple structure, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a novel opening device for a jacquard machine. Background technique [0002] At present, the cloth exported from China needs smooth edges, so many rapier looms of many weaving manufacturers are equipped with tuck-in devices. This conjugate cam is the core component of the tuck-in device. The mechanical structure of the conjugate cam currently on the market is a split type, that is, two cams are assembled after being processed. Because the cam is a kind of component that is difficult to process and detect, especially the two-piece conjugate cam, it is quite difficult to manufacture. The single-piece cam is relatively easy to process, but the conjugate accuracy of the two-piece cam is very low. Difficult to guarantee, the assembled conjugate cam is easy to cause the slack of the assembled fastener during operation and shock vibration, so that the relative position of the two cams...

Problems solved by technology

Because the cam is a kind of component that is difficult to process and detect, especially the two-piece conjugate cam, it is quite difficult to manufacture. The single-piece cam is relatively easy to process, but the conjugate accuracy of the two-piece cam is very low. Difficult to guarantee, the assembled conjugate cam is easy to cause the slack of the assembled fastener during operation and shock vibration, so that the relative position of the two cams will be displaced, the conjugate precision is not good, and the machine will produce shock vibration, rough sound, and accelerate the wear of cams and rollers, and limit the operating speed of the tuck-in device

[0003] Ordinary jacquard machines mostly use eccentric connecting rods or sprockets to directly drive the lifting plate to reciprocate up and down to realize the reciprocating opening, which makes the force extremely unreasonable, the lifting weight is doubled, and the inertial force cannot be balanced to promote the mechanism The movement produces huge vibration, which cannot adapt to high speed and is easy to be damaged and replaced frequently, which makes the maintenance cost high
