Abstract
The utility model relates to an electromagnet needle-select device used in low-speed loom or high-speed loom or single acting upper (middle) opening or double-acting V-shaped opening, which is characterized in that the device adopts two flat needles to replace the vertical needle, namely a static needle (1) comprising a small window (4) comprising two magnetic slices (2,3) with opposite polarity to provide a hanger for a moveable needle by and a moveable needle (6) comprising a hanger (7) with a static needle-hang window and a step (8) for driving lifting knives.
Description
Affiliated technical field
The utility model relate to a kind of on jacquard employed device, the electromagnetic needle selector of a kind of universal high speed electronic jacquard machine of more specifically saying so.
Background technology
The general character of electromagnetic needle selector 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 movement positions be arranged, in order to make perpendicular needle movement reliable, skew and the necessary position of non-migration are clear on flat comprehensive needle selection position, that is to say that should there be certain distance two positions, usually between 2--4MM.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.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art and the electromagnetic needle selector of a kind of universal high speed electronic jacquard machine of providing.This device replaces a perpendicular pin with two flattened needle, the flattened needle that is fixed on electromagnetic valve (9) both sides is called decides pin (1), decides 1 groove (5) is set on the pin (1), wherein studs with 2 opposite polarity permanent magnetic sheets (2,3).Another root is called moving pin with griffing the flattened needle of lifting, and moving pin (6) is provided with to collude hangs hook (7) and step (8) that the confession of being suppressed by plastics is griffed to promote of decide the pin window, as shown in Figure 1.The characteristics of electromagnetic needle selection of the present utility model, as shown in Figure 2, when electromagnet coil (10) cuts off the power supply, the suction that produces by magnetic sheet (2,3) and make and decide the two sides that pin (1) is close to electromagnetic valve (9).When electromagnet coil (10) was switched on, electromagnet (11) produced electromagnetic force under the effect of coil (10) electric current, and its polarity is identical with the polarity of permanent magnetic sheet (2,3), thereby decided pin (1) to be subjected to repulsive force and leave the side of electromagnetic valve (9).This shows and decide pin deflection electromagnetic valve side and leave the electromagnetic valve side all to be applied with positive active force, and, lean on the elastic force of pin to return unlike having only an electromagnetic attraction in other electromagnetic needle selectors.So the utlity model has higher needle selection reliability, guarantee operation steady in a long-term, power consumption is lower simultaneously, need under air conditioner surroundings, not work, and also easy to maintenance.
Another outstanding advantage of the utility model is easy to maintenance; since moving pin with decide pin and separate; when plug electromagnetism valve plate, need not transfer to moving pin; and pulley that moving pin is hung down and heald cord are not driven down without exception; directly pulling up magnetic board can safeguard, changes also easily, tears open and drives a plate and only need 2-3 minute; shorten downtime like this, enhance productivity greatly.
In sum, the utility model can cover all jacquard weave industries, has versatility widely, and its needle selection speed has satisfied the use of high speed inkle loom greater than 1000 times/minute, and its technology is in advanced international standard.
Description of drawings one is of the present utility modelly to decide pin and moving needle construction figure figure two for 1. deciding pin among the moving needle movement state diagram figure in the course of work, 2. magnetic sheet, and 3. magnetic sheet is 4. decided the pin window, 5. bag 6. moves pin, 7. moving pinhock head, 8. step, 9. electromagnetic valve, 10. line bag, 11. electromagnet are 2. griffed
The specific embodiment
Decide pin and moving pin needle selection process is as follows: begin needle selection when pin window (4) is decided in the left side when moving pinhock head (7) moves to, if during electromagnet coil (10) no power, decide pin (1) and be close to electromagnetic valve (9) side, moving pinhock head (7) does not enter decides pin window (4), so moving pin (6) by step (8) with griffe (12) freely move downward, simultaneously the moving pin (6) in right side by step (8) with griffe (12) move upward, when gib head (7) moves to the right side and decides pin window (4), begin needle selection again, if during electromagnet coil (10) energising, because electromagnet (11) produces a repulsive force to deciding pin, make and decide pin (1) and leave electromagnetic valve (9) side, when moving pin (6) by step (8) with griffe (12) be hooked on when moving downward and decide on the pin window (4), at this moment, moving pin (6) can not continue with griffe (12) move downward, thereby realize jacquard weave.
Claims (4)
1. the electromagnetic needle selector of universal high speed electronic jacquard machine, by electromagnetic valve (9) and contain magnetic sheet decide pin (1) and moving pin (6) is formed, it is characterized in that: electromagnetic needle selector constitutes electromagnetic circuit by the iron core of I shape with the permanent magnetic sheet of deciding on the pin.
2. electromagnetic needle selector according to claim 1 is characterized in that: describedly decide to be provided with on the pin (1) groove (5), permanent magnetic sheet (2,3) is arranged in this groove (5).
3. electromagnetic needle selector according to claim 1 is characterized in that: describedly decide the pin lower end one window (4) is arranged.
4. electromagnetic needle selector according to claim 1 is characterized in that: there is a gib head (7) described moving pin upper end.
