Problems solved by technology

[0003] However, as the number of jacquard needles increases, the power consumed by the jacquard itself increases, the volume of the jacquard faucet increases, and the installation height of the jacquard on the loom increases, all of which increase the difficulty of transmitting power from the loom. When the load of the jacquard machine increases too much, beyond the original design of the loom, it will accelerate the damage of the main parts of the loom
[0004] At the same time, since the opening height (that is, the vertical movement displacement of the lifting knife) is required to be adjustable, the height of the front opening and the height of the rear opening are also required to be adjusted separately, which makes the structure of the opening device of the jacquard machine more complicated.

Embodiment 1

[0027] as attached figure 1 The electronic shedding device of the jacquard machine shown includes two sets of lifting mechanisms, and one set of lifting mechanisms consists of the lifting beam 11 and the lifting beam 4 on both sides and is connected between the lifting beam 11 and the lifting beam 4 A plurality of lifting knives 6 are formed (only one lifting knife is drawn in the figure), and another group of lifting knives mechanism is composed of lifting knife beams 12 and knife lifting beams 3 on both sides and a knife lifting beam connected between the two lifting knife beams. It is composed of multiple handles 5 (only one handle is shown in the figure), and two handle beams on the same side are provided with a transmission mechanism, including a transmission mechanism 1, a transmission mechanism 2, a transmission mechanism 9 and a transmission mechanism 10, Each transmission mechanism is composed of a gear and a chain tensioned on the gear. The two ends of each chain are...

Embodiment 2

[0032] The structure in embodiment two is basically the same as that in embodiment one, the difference lies in the transmission mechanism, as attached figure 2 As shown, the transmission mechanism 1' and the transmission mechanism 9' are transmitted through the transmission shaft 7, and the transmission mechanism 2' and the transmission mechanism 10' are transmitted through the transmission shaft 8, that is, in this specific embodiment, the transmission mechanism 1' and The transmission mechanism 2' is used as the driving side, and the transmission mechanism 9' and the transmission mechanism 10' are used as the driven side. Therefore, only two motors described in Embodiment 1 are required to drive the transmission mechanism 1' and the transmission mechanism 2' respectively. The combination of gears and chains can still be selected for the four transmission mechanisms. The connection mode between each transmission mechanism and the knife lifting mechanism is the same as that in...

Embodiment 3

[0035] The structure of the third embodiment is basically the same as that of the first embodiment, the difference lies in the transmission mechanism, as attached image 3 As shown, the transmission mechanism 1", the transmission mechanism 2", the transmission mechanism 9" and the transmission mechanism 10" are belt transmission mechanisms. The synchronous belt between the two, the connection mode of the knife lifting mechanism is the same as the connection mode in the first embodiment, and will not be repeated here, wherein the driving wheels are respectively connected to the output ends of the motor (shown in the figure) described in the first embodiment. Connection, the two lifting beams on the same side are respectively connected with the synchronous belts moving in opposite directions, so that when the angular displacement output by the motor makes the driving wheel rotate forward or reverse at a certain angle, it drives the synchronous belts on both sides to reciprocate u...

Abstract

The present invention relates to an electronic shedding device of a jacquard machine. Said device comprises at least two groups of synchronous jointing tool mechanism performing a up and down reciprocating motion with each group comprising jointing tool beams set at both ends, a plurality of jointing tools connected between two jointing tool beams; a plurality of motors transforming input electric signals into angular displacement output and running synchronously to a weaving machine; a plurality of transmission mechanisms connected to output terminals of motors and used for transforming the angular displacement of motor output into linearity displacement, and connected to two jointing tool beam locating at the same side for driving two groups of jointing tool mechanisms to perform synchronous up and down reciprocating motion. Furthermore, the present invention is also capable of adopting a linear motor to drive the jointing tool mechanisms to perform up and down reciprocating motion,meaning that the present invention replaces a mechanical shedding device in a conventional jacquard machine with an electronic shedding device. Therefore, by removing a complicated cam connecting rodmechanism, said device having a simple mechanical structure is capable of running stably with reduced vibrations, which shedding height is capable of being not mechanically but electrically adjusted.
