Description

The leaf hook slide controller of electronic jacquard machine

Technical field

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

Background technology

The leaf hook slide controller of existing electronic jacquard machine, the Healds rod positioner that uses on the broadcloth electronic jacquard machine as the Britain Bao Nasi machinery BonasMachine Company Ltd of Co., Ltd design, the housing of this device is microscler working of plastics, spacing between its left surface and the right flank is inequality, middle left and right side partly is a parallel surface, from front view, the left and right side, top is splayed, the left and right side of bottom and left and right side, top are symmetrical, the left and right side, top and the bottom is partly far away more far from the centre, and the spacing between the left and right side is more little; The front and back on top is installed a permeability magnetic material plate respectively, and 2 solenoids are housed between 2 permeability magnetic material plates, and hook is positioned at housing top and with the housing injection molded; First and second heald bars are griffed to drive by first and second respectively and are pumped, when rising, first heald bar puts in place and during the solenoid energising, owing to be subjected to electromagnetic attracting force, the first heald bar upper end is offset to the inside to be stopped hanging on first hook, second heald bar rising subsequently puts in place, be subjected to electromagnetic attracting force to stop hanging on second hook, this moment, corresponding warp thread was raised the formation shed open that puts in place.Above-mentioned heald bar also is called the sheet hook, and Healds rod positioner also is called leaf hook slide controller or electromagnetic valve.The defective of prior art: the one, heald bar is to rely on electromagnetic attracting force and stop hanging on the hook, yet magnetic gap is bigger between heald bar and the housing upper side, and magnetic gap reaches 1～2mm usually, consequently under the situation of equal coil, the electric current of coil electricity is bigger, the coil temperature rise height; The 2nd, the front and back on housing top must be installed permeability magnetic material to improve magnetic circuit; The 3rd, there are remanent magnetism in coil and permeability magnetic material behind coil blackout, because coil, permeability magnetic material and heald bar close together, remanent magnetism needs certain hour just to eliminate gradually behind the coil blackout, heald bar top just relies on self elasticity and breaks off relations, because remanent magnetism exists, misoperation can occur and influence the further raising of weaving speed.

Summary of the invention

The purpose of this utility model provides a kind of leaf hook slide controller of electronic jacquard machine of novel structure, by strengthening sheet hook rigidity, and sheet is hooked in to griffe to drive down only makes rectilinear motion up and down in the vertical groove of housing both sides, make coil away from hook, thereby overcome the adverse effect of remanent magnetism, improve the reliability of controller work, can improve the weaving speed of loom significantly.

A kind of leaf hook slide controller of electronic jacquard machine, comprise frame, griffe, housing 1, location washer 2, sheet hook 3, coil 4, housing 1 and location washer 2 are fixed on the frame, griffing to drive sheet hook 3 pumps, it is characterized in that housing 1 both sides are provided with the vertical groove 1a that feed hook 3 slides, the both sides on its top have breach, and 2 double armed levers 6 are housed in the housing 1, this double armed lever 6 is fixed on the housing 1 by pivot pin 7, magnet steel 5 is posted in its inboard, bottom, and the upper end is bent to form hook 6a, the double armed lever 6 of the same side laterally, magnet steel 5, hook 6a is connected as a single entity, coil 4 is arranged between 2 magnet steel 5, connect with back-moving spring 8 between 2 double armed lever 6 tops, the polarity ordering of magnet steel 5 is followed successively by NS-NS, perhaps SN-SN from left to right.

Double armed lever 6 can be swung flexibly around pivot pin 7, the double armed lever 6 of the same side, magnet steel 5, hook 6a is connected as a single entity, setting is positioned at the sheet hook of housing the same side, griffe, hook is first hook, first griffes, first hook, the sheet hook of opposite side, griffe, hook is second hook, second griffes, second hook, griffe to promote by first when first hook 3 and put in place, coil 4+-when end is switched on, first hook 3 stops hanging on the open first hook 6a, second hook 3 griffed to promote by second and put in place subsequently, coil 4 work, second hook 3 stops hanging on the second hook 6a, forms shed open.During coil 4 outages, under the effect of back-moving spring 8, hook 6a resets immediately.

With prior art relatively, the utlity model has following outstanding advantage: 1) coil and magnet steel are contained in enclosure interior and away from hook, can eliminate the adverse effect of remanent magnetism; 2) the sheet hook is pasting the housing side and is not bending along the groove moving linearly, and no magnetic gap exists, and the coil electricity electric current is little, and temperature rise is low, and power consumption is little; 3) be provided with magnet steel and back-moving spring, the hook flexible movements are reliable; 4) simple in structure, cost is low, complete machine working stability, weaving speed reach 800～1200 shuttles/minute.

The drawing explanation
