Abstract
The utility model relates to a selecting needle device of a high-density low-power consumption electronic jacquard, characterized in that a vertical needle which is connected with a lifter is driven by the movable end of an armature of an electromagnet to deflect and finish selecting the needle; and simultaneously a permanent-magnet piece is added between the armature and the vertical needle, thereby ensuring that the vertical needle is clung on one side of the armature, and largely advancing the reliability of the needle selecting. The utility model has another characteristic that the utility model employs the component structure. The size of the smallest component is 6*28mm<2>. The movement of the armature is that the movable end of the armature is pushed to a magnetic pole of the electromagnet through the armature block on the vertical needle is acted by a lifting knife. The clearance is quite small. Thereby, under the quite small power (not larger than 200MW), the armature is in an adhesive condition, and the release of the armature is realized through the constriction of a tension spring.
Description
Affiliated technical field
The utility model relate to a kind of on jacquard employed device, the needle selecting device of a kind of high density of more specifically saying so, low-power consumption, the universal electric jacquard that can in jacquard, use.
Background technology
The general character of needle selecting device is the effect by electromagnet in the electronic jacquard machine, make the perpendicular pin that moves up and down produce or not produce the position skew, thereby make perpendicular needle set that different deviation posts be arranged, in order to make perpendicular needle movement reliable, clear in the flat skew or the necessary position of non-migration of erecting pin on the needle selection position of combining, that is to say that should there be certain distance two positions, usually between 2--3MM.In the prior art, needle selecting device generally is to be made of the electromagnetic valve of a fixed position and perpendicular pin, electromagnetic valve is made of valve body and electromagnet, perpendicular pin is made by sheet metal, if electromagnet is switched on, then perpendicular pin is also directly hung on the valve body by electromagnetic actuation, if the electromagnet no power during work, then perpendicular pin breaks away from valve body by its elastic force, returns to the equilbrium position.The shortcoming of this type of needle selecting device is: it is big to produce remanent magnetism during the high speed adhesive, cause to discharge difficulty, the manufacture process requirement strictness, the electromagnetism power consumption is big, ordinary maintenance is very inconvenient, so easily produce misoperation and require lower environment temperature when using in the high-velocity electrons jacquard.
Though in patent 98233276.9 and 98233275.0, use magnetic sheet to reduce remanent magnetism and power consumption, as shown in Figure 1.But,, therefore be difficult to produce in batches so draw point is required to carry out the strictness debugging because electromagnet directly drives draw point.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned patent and the needle selecting device of a kind of general electronic jacquard machine that provides, as shown in Figure 2.This device will erect pin (4) and change into by electromagnet armature (2) and promoting, change two permanent magnetic sheets into a magnetic sheet (3), this magnetic sheet is installed on the armature, by the effect of permanent magnetic sheet, prevent the perpendicular shake of pin in migration process, improve the reliability of needle selection greatly.Because use armature to promote perpendicular pin, armature (2) should rotate around a garden heart (10) so.
When the utility model needle selecting device uses in single-lift jacquard, in order to reduce open height, improve the stability of machine operation, by the effect of fixed pulley, under same open height, shorten the stroke that half is griffed, this fixed pulley (8) is connected on the perpendicular pin end, do elevating movement with perpendicular pin, chain wheel rope (14) one ends on the fixed pulley (8) are fixed, and the other end connects heald (9).
The perpendicular pin that the utility model needle selecting device uses, the upper end is a steel disc, the lower end is plastics, can lifting in needle track (12), because employing the utility model needle selecting device so the processing of steel disc is not had specific (special) requirements, can drop into batch process.Because electromagnet and armature adopts is soft iron material, then remanent magnetism seldom can satisfy the requirement of high speed needle selection again.
The electromagnet of the utility model needle selecting device adopts " " type clapper-type electromagnetic system that uses in the general relay, and winding directly is wound on the iron core of insulation, and sensitivity is higher, and armature can move more flexible around the fixed point rotation.
The utility model needle selecting device adopts modular structure, except that fixed pulley, all is installed in one 6 * 28 the integrated package among Fig. 2, is combined into a unit block by 16 integrated packages.
The utility model needle selecting device, owing to adopt the low level needle selection, the needle selection reliability increases, power consumption is extremely low, does not require the air-conditioning temperature-reducing environment, and maintenance easily can be changed any shedding parts separately.
In sum, the utility model can cover all jacquard weave industries, has versatility widely, and its technology is in advanced international standard.
Description of drawings Fig. 1 is that the needle selecting device Fig. 2 that uses at present is that embodiment structure chart Fig. 3 of the present utility model is 1. electromagnet among the needle selection process status figure figure, 2. armature, and 3. permanent magnetic sheet, 4. perpendicular pin, 5. armature pushing block, 6. spring,
7. griffe, 8. fixed pulley, 9. heald, the 10. armature garden heart, 11. gib heads, 12. needle tracks,
13. the line bag, 14. chain wheel ropes.
The specific embodiment
The utility model adopts the low level needle selection, when perpendicular pin during: if when the left side electromagnet is in to electricity condition in extreme lower position, griffing to be installed in the extruding that the armature pushing block (5) on the perpendicular pin (4) is griffed under the effect of (7), drive the magnetic pole of armature movable end near electromagnet (1), because armature movable end is very little with gap between the magnetic pole of electromagnet, under very little electrical power, can produce very big suction, be enough to overcome the effective pull of spring (6), keep attracting state, shown in Fig. 2 left side.By the perpendicular pin of permanent magnetic sheet (3) sorption, when griffing to rise, the gib head of this perpendicular pin (11) is not hooked on griffes on (7), thus perpendicular pin do not rise with griffing, shown in Fig. 3 left side; If the right side electromagnet is in when not giving electricity condition, because the contraction of extension spring (6), armature rotates around fixed point (10), make armature movable end leave the magnetic pole of electromagnet, shown in Fig. 2 right side, perpendicular pin produces due inclination under the promotion of armature, the gib head (11) of perpendicular pin is hooked on the griffing of rising (7), and perpendicular pin rises with griffing.Shown in Fig. 3 right side.
Claims (4)
1. the needle selecting device of highly dense low consumption universal electric jacquard, by electromagnet (1) and armature (2) and perpendicular pin (4) formation, it is characterized in that: electromagnet and armature constitute magnetic loop, and perpendicular pin is near armature.
