Abstract
The utility model relates to an electromagnetic needle selecting device for an electronic jacquard of a shuttle loom, which mainly solves the defects that the existing electromagnetic needle selecting device is not suitable for the shuttle loom with a large opening due to a small opening, is not suitable for large jacquard fabrics which are over 2688 needle due to small volume, etc. The utility model comprises a valve body, a vertical needle, an electromagnet and a needle support plate. The utility model is characterized in that two electromagnets are arranged on the valve body, an iron core between the two electromagnets are provided with a magnetic shielding piece, and the needle support plate carries out up-and-down movements. The utility model can be suitable for various electronic jacquards of shuttle looms.
Description
The utility model relate to a kind of on jacquard employed device, specifically a kind of on the fly-shuttle loom electronic jacquard machine employed electromagnetic needle selector.
In the prior art, the electromagnetic needle selector that is used on the electronic jacquard machine is that an electromagnet is installed on an electromagnetic valve body, drive the hard pin of sheet of electromagnetic valve body both sides, hang a warp thread by the hard pinhock of sheet, under the alternating action of griffing up and down, realize Warp opening, promptly belong to this kind structure as Chinese patent 95203911.7.Mainly there are following two shortcomings in this needle selecting device: the one, and its opening is little, is unsuitable for using on the electronic jacquard machine of the fly-shuttle loom of big opening; The 2nd, its volume is excessive, the figurative jacquard that incompatible 2688 pins are above, or will extend and griffe, complexity, making difficulty, production cost improve more to cause whole needle selecting system.
The purpose of this utility model is to provide a kind of opening big, the electromagnetic needle selector of the electronic jacquard machine that adaptation is used on the fly-shuttle loom of big opening, the volume of this electromagnetic needle selector is little, not only can adapt to the jacquard fabric of little pin number, and can adapt to the above figurative jacquard of 2688 pins.
For finishing above-mentioned purpose, technical solution provided by the utility model is: a kind of electromagnetic needle selector of fly-shuttle loom electronic jacquard machine, the electromagnet that comprises valve body 2, perpendicular pin 1, constitutes by electromagnetic core and coil, and the holder needle plate 8 that is positioned at perpendicular pin 1 below, described perpendicular pin 1 is provided with two opposite polarity permanent magnets 5, its special character is, on described valve body 2, be provided with two electromagnet 3,4, described holder pin 8 is the holder needle plates that can move up and down, first line 9 of described perpendicular pin 1 direct hook, first line 9 pass holder needle plate 8.
Between the electromagnetic core of two electromagnet 3,4 described in the above-mentioned technical solution magnetic screen sheet 6 can be set, can reduce so between the two because of influencing each other that leakage field produces.
The accompanying drawing drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the structural representation of this embodiment after perpendicular pin 1 quilt pushes away valve body 2;
Fig. 3 is this embodiment motion state schematic diagram in use.
Each label declaration is as follows among the figure:
1-erects pin 2-valve body 3,4-electromagnet
5-permanent magnet 6-magnetic screen sheet 7-cushions needle guard
The first line 10-of 8-holder needle plate 9-griffes
Referring to Fig. 1, Fig. 2 learns, this needle selecting device has valve body 2, valve body 2 is provided with two electromagnet 3,4, these two electromagnet 3,4 are made of the electromagnetic core and the coil that are fixed on the valve body 2 respectively, be provided with a magnetic screen sheet 6 between two electromagnetic cores, perpendicular pin 1 is positioned at valve body 2 both sides, the inboard of perpendicular pin 1 respectively is provided with a groove, be provided with two opposite polarity permanent magnets 5 in this groove, the lower end of perpendicular pin 1 is provided with the plastics buffering needle guard 7 of buckle, holder needle plate 8 is positioned at the below of perpendicular pin 1, this holder needle plate 8 can move up and down, holder needle plate in its structure and motion mode and the existing jacquard on the mechanical type needle selecting device is identical, and first line 9 of lower end hook of buffering needle guard 7, this head line 9 pass the line hole on the holder needle plate 8.During use, if electromagnet 3,4 is a power failure state, then perpendicular pin 1 leans against valve body 2 one sides under the driving of permanent magnet 5, as shown in Figure 1; If electromagnet 3,4 be electricity condition, it produces magnetic field under the effect of electric current, this magnetic force is identical with the magnetic pole of permanent magnet 5, under the double action of repulsive force and perpendicular pin elastic force, perpendicular pin 1 will be shifted to and leave valve body 2 one sides, as shown in Figure 2.
Referring to Fig. 3, the figure shows the foregoing description different operating state in use.First position is played on a left side among the figure, griffes 10 in extreme lower position, and holder needle plate 8 is comprehensive mean place in the extreme higher position, and perpendicular pin 1 gib head exceeds griffes 10 1 idle running distances; Second position, at comprehensive mean place, two electromagnet 3,4 on the valve body 2 are dead electricity all, and perpendicular pin 1 is leaned against valve body 2 both sides by the electromagnet wicking, and perpendicular pin 1 gib head so descend with holder needle plate 8, forms lower layer warp yarns away from griffing 10; The 3rd position, at comprehensive mean place, two electromagnet 3,4 on the valve body 2 all electric, perpendicular pin 1 is repelled by electromagnetic force, away from valve body 2 both sides, perpendicular pin 1 is hooked on griffes on 10,10 rises with griffing, and forms top line; The 4th position, at comprehensive mean place, valve body 2 left side electromagnet 3 dead electricity, right side electromagnet 4 electric, then the perpendicular pin 1 in left side descends with holder needle plate 8, the perpendicular pin 1 in right side 10 rises with griffing, and forms lower floor and top line respectively; The 5th position, at comprehensive mean place, valve body 2 left side electromagnet 3 get electric, right side electromagnet 4 dead electricity, just the perpendicular pin 1 in left side is with griffing 10 risings, and the right side is erected pin 1 and is descended with holder needle plate 8, forms the upper and lower warp thread respectively.
Can find out that in conjunction with above-described embodiment the utility model has following advantage compared to existing technology:
1, at a valve body two needle selection electromagnets are installed, are driven respectively perpendicular pin, but every perpendicular pin hook A warp thread griffing and holding in the palm under the alternating action of needle plate and realize Warp opening, makes its opening big, can be suitable for Fly-shuttle loom at big opening uses.
2, because its volume is little, not only can adapt to little pin and count jacquard fabric, also can adapt to above big of 2688 pins Jacquard fabric, thereby and make whole needle selecting system simple, be easy to produce, production cost reduces.
