Abstract
The present invention relates to a jacquard weave chip-hook lash-selecting mechanism for an electronic jacquard, which is characterized in that a pair of double armed levers 5 which are symmetrical mutually are arranged in a shell body 1, wherein the double armed levers 5 are crosswise sheathed on a pin shaft 7 in a slide mode, and the pin shaft 7 is fixed on the shell body 1. The upper end of each double armed lever 5 forms a hook 5a, and permanent magnets 6 are respectively arranged in the inner side of the lower ends of the double armed levers, wherein an electromagnetic valve 4 is arranged between the two permanent magnets 6. Compared with the prior art, the present invention has the advantages that the electromagnetic valve and the permanent magnet are far away from the hook without magnetic gaps and a spring, which avoids the influence of remanence; action time is controlled by the time length of powered-one current so as to meet the requirements for high speed; an electromagnetic coil has small powered-on current, low temperature increase and small power dissipation; with simple structure, flexible and reliable action of the hook, high efficiency and low cost, the present invention is superior to the prior art, and is suitable for various jacquards with high speed.
Description
Technical field
The present invention relates to a kind of double-lift electronic jacquard machine, particularly a kind of pattern bit hook lash-selecting mechanism of electronic jacquard machine.
Background technology
The pattern bit hook lash-selecting mechanism of traditional electronic jacquard machine is in the plastic casing top front face of this mechanism and the back side 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 on the hook about stopping respectively to hang over, and this moment, corresponding warp was raised the formation shed open.Technical scheme as CN 91104341.1 is to have in the two sides of housing for the flexible through hole of hook, two hook levers and electromagnetic valve are contained in the inside of housing, the lever that is connected as a single entity with hook is sleeved on the pivot pin, pivot pin is fixed on the housing, two hook inboards are connected by spring, pivot pin is fixed on the housing, and the bar magnet of electromagnetic valve is arranged in the below of lever, and the electromagnetic valve bar magnet stretches between two levers.When the electromagnetic valve circle was switched on, hook stretched out hull outside respectively; During outage, since spring action, hook withdrawal enclosure interior.Its defective is: adopt spring reset, in long-time high-speed cruising process, the spring fatiguability lost efficacy, and caused the hook action malfunctioning, influenced service life.
Summary of the invention
A kind of pattern bit hook lash-selecting mechanism of electronic jacquard machine, comprise and griffing, housing 1, location washer 2, sheet hook 3, electromagnetic valve 4, double armed lever 5, permanent magnet 6, pivot pin 7, housing 1 and location washer 2 are fixed on the frame, griffe to drive sheet hook 3 and pump, housing 1 both sides are provided with the vertical groove 1a that arranges sheet hook 3 usefulness, have through hole on its both sides, top predetermined position, double armed lever 5 is arranged in the housing 1, bearing pin 7 is fixed on the housing 1, and inboard, double armed lever 5 bottom is equipped with permanent magnet 6 respectively, and electromagnetic valve 4 is arranged between two permanent magnets 6, it is characterized in that: double armed lever 5 intersections slide on the bearing pin 7, and these double armed lever 5 upper ends are provided with hook 5a and limit body 5b.The polarity of its polarity and two permanent magnets 6 is to repel mutually during electromagnetic valve 4 energisings; During outage, permanent magnet 6 is inhaled mutually with the iron core of electromagnetic valve 4, plays reset response.
The pattern bit hook lash-selecting mechanism course of work as shown in Figure 1, during electromagnetic valve 4 energisings, open the bottom of double armed lever 5, the through hole outside that hook stretches out housing 1 simultaneously, about sheet hook 3 under griffing to drive, successively stop hanging on the hook 5a, this moment, corresponding warp thread was raised the formation shed open; When electromagnetic valve 4 outages, the left and right sides, double armed lever 5 bottom permanent magnet 6 is inhaled mutually with the iron core of electromagnetic valve 4, in the through hole of hook 5a withdrawal housing 1 both sides.
With prior art relatively, the present invention has following outstanding advantage 1) electromagnetic valve and permanent magnet be away from hook, no magnetic gap, no spring, elimination remanent magnetism influences; 2) come the control action time with the electric current length of conduction time fully, to satisfy demand at a high speed; 3) the solenoid electrical current is little, and temperature rise is low, and power consumption is little; 4) simple in structure, the hook flexible movements are reliable, and the efficient height is better than prior art, and cost is low, is applicable to all kinds of high speed jacquard machines.

The specific embodiment
Embodiment 1:
A kind of pattern bit hook lash-selecting mechanism of electronic jacquard machine, structure as shown in Figure 1, sheet hook 3 thickness are 0.5mm, place in the groove 1a of housing 1 both sides, pump by griffing to drive, stroke is 80mm, hook 5a lateral displacement is 2.5mm, and the electromagnetic valve coil number of turn is 2000 circles, energising piezoelectricity 24V, electric current is 100mA, during electromagnetic valve 4 energisings, double armed lever 5 opens, and the sheet hook 3 that puts in place that successively rises stops respectively to hang on the hook 5a, corresponding warp thread is raised, and forms shed open; During the electromagnetic valve outage, by the power that attracts each other of permanent magnet 6, hook 5a resets, and weaving speed is per minute 1000 times.
