Description

The leaf hook slide controller of electronic jacquard machine

Technical field

The present invention relates to a kind of double-lift electronic jacquard machine, particularly a kind of leaf hook slide controller of electronic jacquard machine.

Background technology

Traditional Healds rod positioner, as a kind of Healds rod positioner that is used for loom that CN89107890.8 provides, each Healds rod positioner contains a holder part, a pair of solenoid, a pair of pole piece.The both sides on support top extreme direction on it is tapered, the both sides of support bottom are tapered towards its following extreme direction, a turning point or oncus are arranged between the upper and lower, the edge of both sides, support top is respectively equipped with groove, support top has two openings that are used to arrange solenoid, the limit wall of a pair of pole piece is installed in respectively on the above-mentioned groove, by rivet solenoid is fixed on the pole piece, this rivet guarantees to have good magnetic contact between solenoid and the pole piece, and the thickness of the degree of depth of groove and pole piece limit wall should be selected like this, when pole piece is rack-mount, the central elevation part of support side should be stretched out the outer surface of limit wall, link up with on the appropriate location of the lateral parts that is positioned at protuberance, and form with support; A pair of pole piece is when solenoid is activated, and one of them pole piece forms the N utmost point, and another pole piece forms the S utmost point.At the heald bar that support both sides work pumps, when coil was activated, heald bar successively stopped to hang on the hook, and corresponding warp thread is raised the formation shed open.At this moment, the part that heald bar surpasses turning point is in case of bending, because support both sides central elevation is partly stretched out the outer surface of pole piece, when heald bar stops hanging on the hook, between heald bar and pole piece, can form a space, have several Healds rod positioners to be fitted together, the used positioner quantity of loom can be handled the maximum quantity of warp thread corresponding to this loom, and described heald bar also is called the sheet hook.The defective that this scheme exists is:

1) heald bar is to rely on electromagnetic attracting force and stop hanging on the hook, and heald bar does not contact with pole piece, has magnetic gap between the two, and the electric current that causes activating solenoid is bigger, the coil temperature rise height;

2) behind the coil blackout, coil and pole piece have remanent magnetism to exist, and can influence the further raising of weaving speed;

3) the frequent crooked of heald bar can influence its service life.

CN 91104341.1 provides a kind of control device of comprehensive bar descending operation, described heald bar is also referred to as the sheet hook, this control device is that a pair of double armed lever is set in housing, double armed lever is installed on the housing by pivot pin, the upper arm outside of each double armed lever is provided with the projection of an energy locking plate hook, the both sides of housing have breach corresponding to the prominence of double armed lever, the hole of haunting as projection, between the upper arm inboard of a pair of double armed lever, connect with spring, a vertical electromagnetic wand of arranging is housed between its underarm, and this electromagnetic wand is made by magnetic material, and the electromagnetic wand bottom is provided with an electromagnet; When electromagnet was switched on, electromagnetic wand produced magnetic pole N-S, and its magnetic force overcomes the elastic force of spring, and this moment, the underarm of double armed lever was open, and play in the projection indentation housing of hook effect, and sheet is hooked in to griffe to act on down and keeps pumping; In case during the electromagnet no power, the magnetic force of electromagnetic wand disappears, under the elastic force effect of spring, two projections are stretched out hull outside and are pinned the sheet hook, and corresponding warp thread is raised the formation shed open.The advantage of this scheme is that the two sides of housing are smooth planes, and the sheet hook is not bent, long service life, and the volume that its defective one is electromagnet and electromagnetic wand is bigger, and it is compact that structure is owed; The 2nd, during the electromagnet energising, in the projection indentation housing, the not jacquard weave of sheet hook, and during the electromagnet no power, it is fixed to the sheet hook lock that projection is stretched out hull outside, the jacquard weave of sheet hook is because the period sum of not jacquard weave of sheet hook is much larger than sheet hook jacquard weave period sum, promptly in the most of the time of jacquard weaving machine operation, electromagnet is in "on" position, consequently power consumption is big, and the electromagnet temperature rise is unfavorable for improving the weaving speed of loom.

Summary of the invention

The leaf hook slide controller that the purpose of this invention is to provide a kind of electronic jacquard machine of novel structure can overcome the adverse effect of remanent magnetism, improves the reliability of controller work, can improve the weaving speed of loom again significantly, reduce the coil electricity electric current, temperature rise is lower, and power consumption is littler.

A kind of leaf hook slide controller of electronic jacquard machine, comprise housing 1, location washer 2, sheet hook 3, coil 4, double armed lever 6, bearing pin 7, spring 8, housing 1 and location washer 2 are fixed on the frame, and two double armed levers 6 are installed on the housing 1 by bearing pin 7 respectively, its upper end is bent to form hook 6a laterally, the both sides of housing 1 are provided with the groove 1a that feed hook 3 works pump, and its top has breach with the corresponding position of hook 6a, connects with spring 8 between two double armed lever 6 tops, it is characterized in that: inboard, two double armed lever 6 bottoms is posted magnet steel 5 respectively, coil 4 is arranged between two magnet steel 5, and the ordering of the polarity of magnet steel 5 is followed successively by NS-NS from left to right, perhaps is SN-SN.Double armed lever 6 can be swung flexibly around bearing pin 7, the double armed lever 6 of the same side, magnet steel 5, hook 6a are connected as a single entity, setting be positioned at the same side the sheet hook, griffe, link up be first hook, first griffe, first the hook, the sheet hook of opposite side, griffe, link up be second hook, second griffe, second the hook, when first hook 3 by first griffe to promote put in place, coil 4+-when energising end, first hook 3 stops hanging on the open first hook 6a, second hook 3 griffed to promote by second and put in place subsequently, second hook 3 stops hanging on the open second hook 6a, forms shed open.During coil 4 outages, under the effect of spring 8, hook 6a resets immediately.

With Healds rod positioner relatively, advantage of the present invention is: coil and magnet steel are contained in enclosure interior and away from hook, can eliminate the adverse effect of remanent magnetism; The sheet hook is pasting the housing side and is not bending along the groove moving linearly, and no remanent magnetism exists, and the coil electricity electric current is little, and temperature rise is low, and power consumption is little; Be provided with magnet steel and spring, the hook flexible movements are reliable; Compare with the control device of combining the bar descending operation, more compact structure, cost is low, weaving speed is higher, reach 800～1200 shuttles/minute.
