Abstract

The present invention relates to a leaf hook lash selecting mechanism for an electronic jacquard, which is characterized in that reeds (5) arranged longitudinally are respectively arranged on a coil (3) and both sides of an iron core (3'), wherein the lower ends of the reeds are respectively fixed on a shell body (1), and the upper end of each reed is respectively provided with a pull hook (6) used for pushing the upper part of a leaf hook (2) to move inwards, or the upper end of each reed is respectively provided with a pushing arm (7) used for pulling the leaf hook (2) to move outwards. Compared with the prior art, the present invention has the advantages that the action of the leaf hook is free from the influence of remanence, the reeds have flexible and reliable action, the current in the coil after powering on is small and the power is only 2 watts. The present invention also has the advantages of low temperature rise, simple structure and low manufacturing cost.

Description

A kind of sheet hook lash-selecting mechanism of electronic jacquard machine

Technical field

The present invention relates to a kind of double-lift electronic jacquard machine, particularly a kind of sheet hook lash-selecting mechanism of electronic jacquard machine.

Background technology

The sheet hook lash-selecting mechanism of traditional electronic jacquard machine is at the front and back on the plastic casing top of this mechanism a permeability magnetic material plate to be installed respectively, 2 solenoids are housed between the permeability magnetic material plate, and the hook of sheet hook is positioned at the left and right side on housing top and with the housing injection molded; The sheet hook pumps by griffing to drive, when solenoid switch on the electromagnetic force of generation respectively the sheet hook is sucked about link up with.Its defective is: the sheet hook is to rely on electromagnetic attracting force and stop hanging on the hook, because magnetic gap is bigger between sheet hook and the housing upper side, common magnetic gap reaches 1～2mm, so the coil electricity electric current is bigger, temperature rise, and remanent magnetism is bigger behind the coil blackout, influences the raising of weaving efficiency.

In the prior art, the someone utilizes telescopic hook, and when hook stretched out hull outside, successively being risen by sheet hook about griffing to drive put in place, and on the hook about stopping respectively to hang over, this moment, corresponding warp was raised the formation shed open.A kind of technical scheme as CN 91104341.1 is: the sheet hook lash-selecting mechanism by housing, electromagnetic valve, slide plate, about hook and stage clip constitute, the two sides of housing have for the flexible through hole of hook, have two symmetries open oblique slot that makes progress on the slide plate, fixedly connected with the bar magnet of electromagnetic valve in its lower end, compression spring sleeve is on bar magnet, the lower end of hook is arranged on the housing by the pin of living, about the hook the middle part protruding pin respectively is housed, this protruding pin slide over respectively slide plate two oblique slots in, and can make arc swing around the sliding pin of lower end.Also drop-down slide plate when magnetized electromagnetic valve affects bar magnet stretches out outside the housing through-hole hook.When electromagnetic valve magnetic force disappeared, stage clip upwards pushed away, and slide plate pushes away on following, and hook resets about making.Its defective is that structure is comparatively complicated, the cost height, and the solenoid electrical current is big, and power consumption is big, temperature rise.

Summary of the invention

A kind of sheet hook lash-selecting mechanism of electronic jacquard machine comprises and griffing, housing 1, sheet hook 2, coil 3 and iron core 3 thereof ', hook 4, griffe to drive sheet hook 2 and pump, housing 1 both sides are provided with the vertical groove of arranging sheet hook 2 usefulness, have through hole on its both sides, top predetermined position.It is characterized in that: coil 3 and iron core 3 ' both sides be respectively equipped with the reed 5 of vertical layout, the bottom of this reed is fixed on respectively on the housing 1, its upper end is equipped with respectively and is used to spur the drag hook 6 that inwards move on sheet hook 2 tops, perhaps is equipped with respectively to be used for pushing piece hook 2 push arm 7 of side shifting outwardly.Adopt the structure of Fig. 1, Fig. 2, when coil 3 energisings, reed 5 is subjected to iron core 3 ' magnetic attraction and inwards moves, and the sheet hook 2 of drag hook 6 pullings successively stops hanging on the hook 4, and corresponding warp thread forms shed open; Adopt the structure of Fig. 3, Fig. 4, when the coil no power, push arm 7 stretches out housing 1 outside, push sheet hook 2 tops open, make the sheet hook not stop to hang on the hook 4, if coil 3 energisings, push arm 7 moves in the housing 1, and sheet hook 2 successively stops hanging on the hook 4, and corresponding warp thread forms shed open.

With prior art relatively, advantage of the present invention is, the influence of remanent magnetism is avoided in the action of sheet hook, and the reed flexible movements are reliable, and the coil electricity electric current is especially little, and energising power is 2 watts only, and temperature rise is low, and is simple in structure, and cost is lower.

The specific embodiment

Embodiment 1:

A kind of sheet hook lash-selecting mechanism of electronic jacquard machine, as shown in Figure 2, the two sides on housing 1 top are the inclined-plane, during coil 3 energisings, its top of sheet hook that puts in place of rising is subjected to drag hook 6 pullings, successively stops to hang on the Hook 4, corresponding warp thread is raised the formation shed open, and weaving speed is per minute 1000 times.Adopt single coil and iron core thereof, its power of coil electricity is 2 watts.

Embodiment 2:

The sheet hook lash-selecting mechanism of another kind of electronic jacquard machine, as shown in Figure 3, Figure 4, the both sides of housing 1 are parallel to each other, and during the coil no power, the sheet hook lash-selecting mechanism is in reset mode; During coil electricity, the sheet hook that puts in place that rises successively stops to hang on the hook, and corresponding warp thread is raised the formation shed open, and weaving speed is per minute 1100 times.Adopt single coil and iron core thereof, its power of coil electricity is 2 watts.
