Electronic shedding device of jacquard loom

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 rod mechanism, 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.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to an electronic opening device of a large jacquard machine. Background technique [0002] The opening device of the traditional jacquard machine includes two groups of lifting mechanism, each group of lifting mechanism includes the lifting beam arranged on the left and right sides, and the lifting knife whose two ends are respectively connected with the lifting beam on the left and right sides, the main shaft of the jacquard machine and The opening device is driven by a combined mechanical structure such as a cam or a link mechanism, thereby converting the rotary motion of the main shaft of the jacquard machine into the up and down reciprocating motion of the lifting mechanism, and the main shaft of the jacquard machine is connected to the main shaft of the loom through a coupling. Therefore, the opening device of the jacquard machine is powered by the moto...

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.
