Description
[technical field]
The utility model relates to a kind of electronic jacquard machine, especially belongs to the electromagnetic needle selector of a kind of adapted on jacquard.
[background technology]
The appearance of Electronic card (or claiming electronic needle selection mechanism for jacquard, electronic figure pattern card etc.) has changed the mode that selecting mechanism that traditional mechanical jacquard relies on mechanical cylindrical fireworks, magic flower mechanism and card to constitute carries out needle selection, and the high purpose of province's material efficient has realized saving time." electronic figure pattern card " of China Patent No. 012394505 (hereinafter to be referred as " patent 1 ") introduced a kind of electromagnetic needle selector for jacquard, and its structure mainly is made of chassis, electromagnet stent, electromagnet and moving iron core, cross bar, actuating coil and resetting coil etc.Electromagnet stent is fixed on the chassis, has the vertical blind hole and the cross through hole of mutual perforation on it, and moving iron core is arranged in the vertical blind hole.When resetting coil was switched on, moving iron core moved down the right part of blocking cross bar, and along with being moved to the left of whole chassis, cross bar drives eedles and is moved to the left, and is considered as card " atresia ", and corresponding warp is sunk.The effect of actuating coil is opposite with resetting coil, during the actuating coil energising, moves on the moving iron core, forms " porose ", makes and carries the formation shed open on the corresponding warp.
A kind of " Electronic card " that China Patent No. 031439950 (hereinafter to be referred as " patent 2 ") relates to, its structure comprises frame, eedles, reciprocating lever, and contain several electromagnetism valve plates and every electromagnetism valve plate by restoring board, substrate, push pin, the bistable state needle selection electromagnetic valve of the stepped distribution of some one-tenth, flexible circuit constitute, described bistable state needle selection electromagnetic valve is made of solenoid valve seat, coil rack, coil, iron core, permanent magnet.Have horizontal pilot hole and vertical special-shaped groove on the solenoid valve seat, one end of coil rack has block, one end has terminals, there is a through hole centre, iron core is placed in the through hole of coil rack, permanent magnet is located at the upper and lower of iron core, the excitation system that iron core and permanent magnet constitute is fixed in the vertical special-shaped groove of solenoid valve seat, but coil rack moves with respect to the iron core easy on and off, one end of flexible circuit is fixed on the terminals of coil rack and with the lead-in wire of coil and is connected, the other end is fixed on the substrate, have on the restoring board and the corresponding through hole of eedles, pushing pin is made of a head and the needle body, and its head is greater than the through hole on the restoring board, the through hole that the afterbody of pushing pin passes on the restoring board is inserted in the pilot hole of solenoid valve seat, and its head leans on mutually with the end of eedles or be mutually close.The principle of this patent is to utilize the forward and reverse electric current in the magnetic of permanent magnet and the coil to change, realize iron core move down or on carry, form " porose " or " atresia " state, compare patent 1 and can omit a resetting coil, thereby simplify the structure.
There are the following problems for above-mentioned known technology: patent 1 adopts actuating coil and resetting coil by moving iron core, forms " atresia " or " porose " state control eedles, realizes shed open, and remanent magnetism is big, complex structure.
[summary of the invention]
For overcoming the problems referred to above, the utility model aims to provide a kind of electromagnetic needle selector for jacquard, and this installs in use, and coil lead phenomenon of rupture, good reliability can not occur.
For achieving the above object, the utility model has adopted following technical scheme:
This electromagnetic needle selector for jacquard, comprise valve body, actuating coil and iron core thereof, has a containing cavity of admitting actuating coil and iron core thereof on the valve body, one side of containing cavity is adjacent with the working face of valve body, it is characterized in that: the front shape of described iron core is " worker " font, side direction is installed in the described containing cavity, and two side end faces of transverse sheet one side of " worker " font iron core expose on the working face of valve body; The working face of described valve body is rectangular, has a projection between two exposed side end faces of transverse sheet, has concave through grooves corresponding to two side end faces on the projection, is equipped with armature pins respectively in two concave through grooves; Concave through grooves is stretched out in described armature pins lower end, offsets with a spring after concave through grooves is stretched out in the armature pins upper end.
Aforesaid needle selecting device is characterized in that: the needle body cross section of described armature pins is a rectangle, and the needle body top of stretching out the concave through grooves upper port has one to expand body portion.
Aforesaid needle selecting device is characterized in that: described projection and valve body split, both are connected into integral body with the dovetail groove plug-in type.
Aforesaid needle selecting device is characterized in that: the other end of described spring and a spring base offset, spring base and valve body split, and both are connected into integral body with the dovetail groove plug-in type.
Aforesaid needle selecting device is characterized in that: described spring base is provided with a projection in the corresponding position of admitting spring, and spring is nested with between projection and armature pins.
Beneficial effect: compared with prior art, the utility model adopts actuating coil, armature pins and spring structure to carry out needle selection, both can omit resetting coil, overcome big, the baroque defective of remanent magnetism, also solve the problem of the connecting line easy fracture between actuating coil and the circuit board.In the work, the spring force of described spring can guarantee that armature pins in time is in reset position, when actuating coil gets electric work, electromagnetic force will be carried in the armature pins adhesive (during adhesive, carry on the whole needle selecting device), " porose " state of realization, actuating coil dead electricity spring force in time resets armature pins, forms " atresia " state.Because in realizing " porose " or " atresia " two states, all be that relative position by armature pins changes and realizes, and the relative position between actuating coil and the circuit board does not change, therefore, there is not the problem of fracture naturally in connecting line.
