Abstract
The utility model relates to a magnetic needle-selecting device for an electronic jacquard, which comprises a vertical needle and an electromagnet which can make the vertical needle generate displacement. The magnetic needle-selecting device for an electronic jacquard is characterized in that the vertical needle is overlapped with one end of a needle-selecting arm; the other end of the needle-selecting arm is hinged with a needle-selecting frame; the needle-selecting frame which is in a hollow tube structure is sheathed on one end of a needle-selecting rod; the other end of the needle-selecting rod is arranged on the lower part of the electromagnet, and the corresponding matched positions of the needle-selecting arm and the needle-selecting rod are respectively provided with a permanent magnet with the same polarity. Processing technique of the electromagnet is simplified; the displacement of the vertical needle is larger, and the magnetic needle-selecting device for an electronic jacquard is not easy to generate needle-selecting errors caused by dithering of the device.
Description
The utility model relates to electronic jacquard machine magnetic force needle selecting device.
Needle selecting device is the vitals of jacquard, and in the existing high-speed weaving machine, electronic jacquard machine has replaced mechanical jacquard.Needle selecting device in the electronic jacquard machine is directly to finish the needle selection task by electromagnet, promptly electromagnet directly with the adhesive and make perpendicular pin generation displacement mutually of perpendicular pin.There is following shortcoming in the magnetic force needle selecting device of said structure: because the line pin of jacquard is more, electromagnet can not be done very greatly, exciting curent also is subjected to the restriction of multiple factor simultaneously, therefore its magnetic force is generally also less, and then when needle selection, the displacement that perpendicular pin is produced is also little, and perpendicular pin has shake that the needle selection mistake just easily takes place slightly.On the other hand, electromagnet is as the strength member of electronic jacquard machine magnetic force needle selecting device, and consumption is big, if cut into conjuncted electromagnet or build up with rammed iron plate with whole block material, then the spillage of material in the process is very big, has further increased the cost of equipment.
The purpose of this utility model be to provide a kind of electromagnet directly with the adhesive mutually of perpendicular pin, but make the needle selecting device of perpendicular pin generation displacement by an interlinked mechanism.
For achieving the above object, the utility model has adopted following technical scheme: a kind of electronic jacquard machine magnetic force needle selecting device, comprise perpendicular pin and can make perpendicular pin produce the electromagnet of displacement, be characterized in that perpendicular pin overlaps mutually with an end of needle selection arm, the other end of needle selection arm and needle selection frame are hinged, the needle selection frame is an end of tubular structure and socket needle selection bar, and the needle selection bar other end is arranged on the below of electromagnet; On the position of above-mentioned needle selection arm and the corresponding coupling of needle selection bar, be respectively equipped with the same polarity permanent magnet, when electromagnet is not switched on, when promptly perpendicular pin was not selected, the permanent magnet of described needle selection arm and needle selection bar was on the position of repelling each other.The needle selection bar is connected with armature near on the end of electromagnet, and when electromagnet was switched on, this armature was connected with electromagnetic actuation.Electromagnet is by the stacked bending of the pure iron sheet structure that takes the shape of the letter U.
Owing to adopted technique scheme, electromagnet directly with the adhesive mutually of perpendicular pin, the processing technology of electromagnet is simplified, as long as the iron plate bending is superimposed, refining losses is little, cost is low.Simultaneously, electromagnet directly with the adhesive mutually of perpendicular pin, but on the position of needle selection arm and the corresponding coupling of needle selection bar, be respectively equipped with the same polarity permanent magnet, rely on the mutual expelling force of permanent magnet to finish the displacement of erecting pin, the magnetic force of permanent magnet unit are is much larger than the magnetic force of electromagnet unit are, and therefore perpendicular pin displacement is bigger, is not easy because of the shake of equipment the needle selection mistake to take place.

To be further described the technical solution of the utility model by drawings and Examples below.
As shown in Figure 1: in the present embodiment, comprise perpendicular pin 1 and can make perpendicular pin 1 produce the electromagnet 2 of displacement, but electromagnet 2 directly with the adhesive mutually of perpendicular pin 1, but make perpendicular pin 1 generation displacement by an interlinked mechanism.Perpendicular pin 1 relies on the elasticity of himself to overlap mutually with an end of needle selection arm 3, the other end of needle selection arm 3 and needle selection frame 4 are hinged, needle selection frame 4 is an end of tubular structure and socket needle selection bar 5, needle selection bar 5 is connected with armature 6 near on the end of electromagnet 2, when electromagnetism iron plate was switched on, this armature 6 can be connected with electromagnet 2 adhesives.On the position of above-mentioned needle selection arm 3 and needle selection bar 5 corresponding couplings, be respectively equipped with the permanent magnet 7 of same polarity.When electromagnet 2 is not switched on, when promptly perpendicular pin 1 was not selected, the permanent magnet 7 of described needle selection arm 3 and needle selection bar 5 was on the position of repelling each other.
As shown in Figure 2: when the needs needle selection, electromagnet 2 is energized excitatory when rising beginning, and move on the adhesive armature 6 drive needle selection bars 5, make the permanent magnet 7 of needle selection arm 3 and needle selection bar 5 break away from the position of repelling each other, perpendicular pin 1 is subjected to displacement under self flexible effect, get back to the position of being mentioned, thereby reach the purpose of needle selection by needle cutter 8.
As shown in Figure 3: electromagnet 2 is by the pure iron sheet 9 stacked bendings structure that takes the shape of the letter U.
