Description

Simple jacquard needle board

The present invention relates to the selecting mechanism of jacquard, specifically a kind of no card selecting mechanism on the jacquard.

Jacquard is the corollary apparatus of loom, mainly is made up of shedding mechanism and selecting mechanism two parts, and 19 beginnings of the century, Frenchman Jia Kate (IM.Jacguard) makes the Jia Kate jacquard, and jacquard still is the indispensable device of weaving big-pattern fabric so far.Traditional selecting mechanism comprises card, cylindrical fireworks, eedles etc., controls the lifting of organizine usually by rolling porose or atresia on card, and porose or atresia and woven decorative pattern on the card match, therefore, a kind of fabric of spending the type kind of every design, just necessary rolling corresponding card, complicated large-scale pattern fabric, required card quantity is big, the reading-off cycle in man-hour is long, the expense height, and, card is subjected to the impact of cylindrical fireworks upset big, has limited the raising of jacquard speed.For this reason, the clear 58-109652 of JP, the clear 60-028541 of JP, JP62-243844 disclose the technical scheme of several relevant selecting mechanisms, wherein the motion of cross bar all is that suction or thrust by calutron produces, i.e. the magnetic field force that is produced by the magnetic plug energising that is contained in the cross bar direction.Because the density of arranging of jacquard eedles is very big, the pin hole spacing only is 4 millimeters, it is suitable difficulty less than 4 millimeters magnetic plug that hundreds of or more than 1,000 diameter is installed on the relative same plane of eedles, the magnetic line of force phase mutual interference that magnetic plug produced of dense arrangement is to cause the principal element that selecting mechanism can not precision maneuver, and, the efficient of magnetic plug is extremely low, promote beam movement, each magnetic plug needs about 10 watts of rated power approximately, in above-mentioned machinery, all adopt synchronous driving mode, required dc source power is huge, the cost height.CN86105745 discloses a kind of " selecting mechanism of knitting machine ", and its selecting mechanism has adopted piezoelectric element, but, the deformation quantity that present piezoelectric element produces in energising is very little, still the difficult control of satisfying beam movement, and CN88203213 disclosed " loom does not have the card jacquard attachment ", be characterized in having used a limited number of pounders, pounder is controlled by microprocessor in rectilinear motion, to the knitting needle completion status set of its scope that impacts.Thereby the more above-mentioned patent of the rated power of required dc source is little, but, the pin number that its a pounder correspondence will be hit is more, and the discreteness of the elastic force of the reed that the pin of each pin colludes is bigger, makes the hitting power of pounder be difficult for adapting to, cause the strike incomplete phenomena easily, moreover the loom bent axle circles for every time, and pounder need hit tens times at least, tens times at most, the working life of pounder generally is difficult to satisfy jacquard attachment and turns round for a long time.

The objective of the invention is to utilize microprocessor data processing speed height, capacity big, revise advantage easily, for loom provides a kind of power consumption little, the needle selection precise control, long working life, jacquard speed is fast, and is simple in structure, the simple jacquard needle board that production cost is low.

Realize that purpose of the present invention mainly is by box body, controller, cross bar, it is characterized in that montant in addition, spring, location-plate, restoring board is formed, before the box body, after, on, correspondence is arranged with multirow row through hole on the lower plate, device had the location-plate corresponding with parallel with the every capable hole of header board in box was stopped, a plurality of location-plates are stepped to be fixed in the lid, on every location-plate pilot hole is arranged, the spacing of two adjacent location-plates is bigger than the diameter of section of cross bar, cross bar be through between the location-plate and head preceding, in the hole of back plate, group's bar is arranged on the cross bar, spring assembly is outside box body on the cross bar, the montant head is last, in the hole of lower plate, controller is installed in an end of the outer montant of box body, on box body, lower plate and each inboard root erect between root and the controller and spring are housed, pilot hole on montant and the location-plate and the corresponding matching device in box body of the group's bar on the cross bar.

The outstanding advantage of the present invention is: 1, the beam movement driving force is compressed spring force, and this power is big more than the suction or the thrust of magnetic plug, and its installation dimension is little, and motion is reliable;

2, adopt the controller of calutron to be installed on montant direction vertically, thereby its installation dimension can expand, can make big helix tube type electromagnetic block, its magnetic circuit seals, and adjacent electromagnetic interference is very little, can not cause misoperation.

3. electromagnet is not to make driving element, and just as a kind of control piece, thereby each electromagnet power demand is little with element power more than doing driving, in addition in the jacquard crank up part-time in one week, by the flower type controller every group of electromagnet (a group about tens) pulse is scanned, thereby required dc source rated power is very little;

4, the jacquard bent axle circles for every time, and electromagnet on average moves 1/2 time, and operating frequency is low, and its working life can adapt to jacquard running year in year out;

5. simple in structure, manufacture craft is less demanding, and production cost is low.
