Abstract

The invention relates to an electronic jacquard machine with electromagnetic valve-jacquard needle linkage. Its features are that the pumping fluctuating plate and the vertical fluctuating plate has the same frequency but opposite sense of displacement; the up quadrate hole of the first and second jacquard needles has different height. Its advantages are that the jacquard machine can reduce electromagnetic valve and jacquard needle by 50% and omit the pulley block and pulley rope to shorten 45% volume, lighten weight, and reduce the cost; because of the vertical fluctuating plate and the fluctuating plate are linkage and their sense of displacement are opposite, the sum of the amplitudes of the raised and descendent warps are equal to opening amplitude to reduce warp strain, broken ends, complete machine abrasion, and prolong the useful life of the jacquard machine.

Description

Solenoid valve-jacquard needle linkage electronic jacquard machine

technical field

The invention relates to a single-action electronic jacquard machine, in particular to an electronic jacquard machine with electromagnetic valve-jacquard needle linkage.

Background technique

Commonly used electronic jacquard machines, such as the heald rod positioning device provided by CN 85109519 and CN 89107890, each jacquard unit of the device contains a solenoid valve made of valve seat, electromagnetic coil, and magnetizer, two hooks, two The jacquard needle, the hook and the valve seat are integrated, and are located on the left and right sides of the upper part of the valve body. If a jacquard unit wants to lift a warp yarn, the first jacquard needle that moves up and down reciprocatingly drives the first jacquard needle to rise to the position. , the electromagnetic coil is energized, and the upper end of the first jacquard needle is attracted by the magnetic force of the magnetic conductor to deviate, so that the first jacquard needle stops hanging on the first hook, and then the second lifting knife that reciprocates up and down drives the second jacquard needle to rise In place, at this point a warp thread is lifted into place. A jacquard unit of the device needs to adopt a solenoid valve and 2 jacquard needles to lift a warp yarn. Obviously, the electronic jacquard machine that adopts this type of device has many components, large volume and high cost.

Contents of the invention

The object of the present invention is to provide an electronic jacquard machine with solenoid valve-jacquard needle linkage. Each solenoid valve is equipped with 2 jacquard needles, and each jacquard needle lifts a warp independently. For jacquard machines with the same number of needles, this solution is adopted , the number of electromagnetic valves and jacquard needles used is reduced by 50%, which has the advantages of fewer parts for the jacquard machine, small size, light weight, and low cost. At the same time, the warp tension is reduced and the service life of the jacquard machine is extended.

An electronic jacquard machine with solenoid valve-jacquard needle linkage, comprising a solenoid valve 1 composed of a valve seat 1a, an electromagnetic coil 1b, and a magnetizer 1c, a first jacquard needle 2a, a second jacquard needle 2b, and the valve seat 1a. The first hook 3a and the second hook 3b are integral, and the heights of the first hook 3a and the second hook 3b are the same. The lifting plate 4 of 2b has a through hole for arranging the first jacquard needle 2a and the second jacquard needle 2b on the lifting plate 4 and the first hinge 4a and the second hinge 4b are housed, and the first rotating shaft 01 and the second hinge 4b of the jacquard machine A first eccentric wheel 5a and a second eccentric wheel 5b are respectively housed on the second rotating shaft 02 of the jacquard machine, and the first eccentric wheel 5a, the second eccentric wheel 5b and the first hinge 4a and the second hinge 4b are connected by a first connecting wheel respectively. The rod 6a is connected with the second connecting rod 6b, the first jacquard needle 2a and the second jacquard needle 2b are equipped with a boss for resting the jacquard needle on the lifting plate 4; there is a longitudinal lifting plate 7 and its guide rail 8, and the solenoid valve 1 Be fixed on the longitudinal lifting plate 7, the third eccentric wheel 9a and the fourth eccentric wheel 9b are respectively housed on the third rotating shaft 03 of the jacquard machine and the fourth rotating shaft 04 of the jacquard machine, the third eccentric wheel 9a and the fourth eccentric wheel 9b are connected with The vertical lifting plates 7 are respectively connected with the third connecting rod 10a and the fourth connecting rod 10b; The height of the square through hole on the 2b is higher than the height of the square through hole on the first jacquard needle 2a; The frequency is the same and the direction of displacement is opposite.

The working process of this electronic jacquard machine is: the frequency of the reciprocating motion of the lifting plate 4 for up and down reciprocating motion and the vertical lifting plate 7 for down and up reciprocating motion is the same, and the displacement direction is opposite, the first jacquard needle 2a and the second jacquard needle 2a The second jacquard needle 2b reciprocates up and down following the lifting plate 4, and the longitudinal lifting plate 7 equipped with a solenoid valve reciprocates up and down. The height of the square through hole on the second jacquard needle 2b is higher than that on the first jacquard needle 2a. In the case of the height of the square through hole, when the first jacquard needle 2a rises to the position, the electromagnetic coil 1b is energized, and the first jacquard needle 2a stops and hangs on the first hook 3a through the square through hole thereon. At this time, the first jacquard needle 2a One jacquard needle lifts the yarn, and the square through hole on the second jacquard needle 2b does not lift the yarn because the height is higher than the first hook 3a; then the second jacquard needle 2b descends with the lifting plate, and when it falls down to the second hook quickly At the moment when 3b is nearly flush, the electromagnetic coil 1b is energized again, and the second jacquard needle 2b hangs on the second hook 3b through the square through hole thereon, and the second jacquard needle 2b lifts the yarn. The warp opening width is 110-130mm, and the opening width is adjustable.

If the height of the square through hole on the first jacquard needle is higher than the height of the square through hole on the second jacquard needle, when the second jacquard needle rises to the right position, the electromagnetic coil is energized for the first time, and the second jacquard needle stops hanging On the second hook, the second jacquard needle lifts the warp yarn, and the first jacquard needle does not lift the yarn; then the first jacquard needle follows the lifting plate and descends to the moment when the square through hole on the jacquard needle is close to being flush with the first hook, and the electromagnetic The coil is energized again, the first jacquard needle stops and hangs on the first hook, and then the first jacquard needle lifts the yarn. Or after the second jacquard needle lifts the yarn for several motion cycles, the first jacquard needle follows the lifting plate and descends to the moment when the square through hole on the jacquard needle is close to being flush with the first hook, and the electromagnetic coil is energized again, then the first jacquard needle Jacquard needle jacquard.

Compared with the prior art, the outstanding advantages of the present invention are: 1) the number of electromagnetic valves and jacquard needles configured by the jacquard machine is reduced by 50%, and the pulley blocks and pulley ropes used with the jacquard needles are omitted, the volume is reduced by 45%, and the weight is reduced by 45%. 2) Since the longitudinal lifting plate 7 is linked with the lifting plate 4, and the displacement direction is opposite, the sum of the lift of the lifted warp yarn and the decline of the unlifted warp yarn is equal to the opening width, so that the warp yarn tension is significantly reduced, The warp broken end is reduced correspondingly, the wear and tear of the whole machine is small, and the service life of the jacquard machine is prolonged.
