Description

Combined electronic jacquard yarn-selecting unit

Technical field

The utility model relates to a kind of double-lift electronic jacquard machine, particularly a kind of combined electronic jacquard yarn-selecting unit.

Background technology

Traditional electronic jacquard yarn-selecting unit, as a kind of vertical screw mandrel detent mechanism that is used for loom that CN89107890.8 provides, each detent mechanism 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 bottom, a turning point is arranged between bottom and the top, the edge of both sides, support top is provided with groove, support top has two openings that are used to arrange solenoid, the edge 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 limit wall of the degree of depth of groove and pole piece 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 magnetic pole strength, when heald bar stops hanging on the hook, between heald bar and pole piece, can form a space, have several heald bar detent mechanisms to be fitted together, the used detent mechanism 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.

Summary of the invention

The purpose of this utility model provides a kind of simple and compact for structure, economy, energy consumption is low, reliable, the electronic jacquard yarn-selecting unit that can be fit to big line pin electronic jacquard machine, control warp thread by the control swing arm, avoided moving up and down of knitting needle, the static that produces, overcome the adverse effect of static and remanent magnetism, improved the reliability of selecting yarn mechanism, can improve weaving efficiency significantly.

A kind of combined electronic jacquard yarn-selecting unit, comprise that several select the yarn unit, each selects the yarn unit to contain housing 1, electromagnet 2, hook 3, drag hook 4, the bottom of drag hook (4) is connected with chain wheel rope, it is characterized in that: be provided with 2 bearing pins 5,2 swing arms 6,2 springs 7 and a guide pad 8, wherein bearing pin 5 is positioned at the outside of electromagnet 2, and becomes one with housing 1, and its back is provided with and another blind hole of selecting the bearing pin of yarn unit to cooperatively interact, the installing hole of swing arm 6 is sleeved on the bearing pin 5, its upper outside is provided with one swing arm 6 is carried out spacing outer lug boss 1a, and its upper inner is provided with the serriform groove 6a of mounting spring 7 usefulness, and serriform groove 6a inboard is provided with inner convex platform 1b, spring 7 is arranged between serriform groove 6a and the inner convex platform 1b, above-mentioned outer lug boss 1a and inner convex platform 1b and housing 1 become one, and hook 3 is positioned at the bottom of swing arm 6, and become one with swing arm 6, guide pad 8 is fixed on the housing 1 between two drag hooks 4; The spigot surface of guide pad 8 is V-shaped, and the coupler body of drag hook 4 is provided with an elasticity and helps and inhale body 4a, and the hook of hook 3 is to the inboard of housing, and cooperatively interacts with drag hook 4.

Griffe to drive drag hook 4 and do and pump, move to highest order when griffing to drive drag hook 4, if the coil no power of electromagnet 2, drag hook 4 successively stops hanging over hook 3 o'clock, and warp thread forms shed open; If the coil electricity of electromagnet 2, swing arm 6 and electromagnet 2 adhesives, hook 4 breaks away from drag hooks 3, if the coil electricity of electromagnet 2, griffes to drive drag hook 4 and does and pump, and warp thread does not form shed open.

With prior art relatively, the utlity model has following advantage: 1) rational in infrastructure simple, the swing arm hunting range is very little, has improved the operating frequency of swing arm, and has improved the production efficiency of loom; 2) drag hook is formed by plastic injection-moulded, and drag hook can not produce static up and down, has avoided electrostatic interference; 3) help the suction body because the lower end of drag hook is provided with elasticity, the gap between swing arm and the electromagnet armature is minimum, and the needed electric current of adhesive is just little; 4) this electronic jacquard yarn-selecting unit magnet spool support is vertical layout, and traditional coil brace that selects yarn mechanism is lateral arrangement, and the coil turn that this mechanism arranged is multiplied, and the electromagnetism the suction-combining force of generation increases, and energising voltage reduces, and reduces power consumption.
