Abstract

The utility model relates to an electronic needle selection mechanism for jacquard machine, including a stand, a coil skeleton, a permanent magnet sheet, and a top needle. A magnet sheet slot and a top needle slot perpendicular to the magnet sheet slot are provided on the stand. Each of the two permanent magnet sheets has one end inserted into the magnet sheet slot, and the other end overhung. Theoverhung ends of the two permanent magnet sheets are same in polarity, and the two permanent magnet sheet are eccentric. The coil skeleton is sleeved on the overhung ends of the two permanent magnetsheets, and capable of up-and-down sliding on the permanent magnet sheets. A coil is wound on the coil skeleton, and a block is provided on one end of the skeleton. The electronic needle selection mechanism for jacquard machine is simple in structure, easy for installation.

Description

The jacquard electronic needle selection mechanism for jacquard

Technical field

The utility model relates to a kind of jacquard electronic needle selection mechanism for jacquard of computer control, belongs to the weaving and knitting preparation field, is applicable to that mainly the mechanical jacquard of card control changes computer control into, is electromechanical integrated product.

Background technology

The big jacquard of domestic traditional machinery is to control eedles with the porose atresia of big string cardboard (thousands of), pushes perpendicular pin and jacquard weave weaves different pattern fabrics.By plan of weave to last machine test weaving, to pass through a series of miscellaneous processes, comprise and re-pack, go here and there knot, last machine debugging etc., expend a large amount of artificial and funds, the production set-up procedure is chronic, and a cover flower type cardboard cost is very high, and it is very difficult to take care of, revise the flower type, complex operation, and electronic jacquard machine price height.Chinese patent ZL03143995.0 " Electronic card " has proposed a method preferably, it is made of the bistable state needle selection electromagnetic valve of some ladder promulgations, the coil rack of this electromagnetic valve has block, coil is inserted in iron core and can slides up and down, two ends unshakable in one's determination respectively are placed with two blocks of permanent magnets, coil is as if the electric current by different directions, magnetic field that coil produced and two ends permanent magnet effect, then coil drive block moves up and down, block blocks or does not block and the corresponding thimble of eedles, and form porose nothing, poroid attitude, thus the perpendicular pin of cardboard control replaced, mention harness cord and weave different pattern fabrics, but this mechanism is still complicated, and the permanent magnet volume is bigger, when needle gage is 4 millimeters (16 row) less than 5.12 (12 rows), relatively difficulty is installed.

Summary of the invention

The purpose of this utility model just provides a kind of jacquard electronic needle selection mechanism for jacquard simple in structure, easy for installation.

Jacquard electronic needle selection mechanism for jacquard of the present utility model, comprise support, coil rack, permanent magnet pieces and thimble, have on the support magnet film trap and with the thimble groove of magnet film trap vertical direction, two permanent magnet pieces end separately inserts respectively in the magnet film trap, the other end is all unsettled, the polarity of two permanent magnet pieces free ends is identical, and two permanent magnet pieces are concentric, coil rack is enclosed within on the free end of two permanent magnet pieces, can slide up and down at permanent magnet pieces, the outside of coil rack is wound with coil, and coil rack is provided with block.

Jacquard electronic needle selection mechanism for jacquard of the present utility model is simple in structure, easy for installation, and its operation principle is, when feeding forward current in the coil of coil rack, coil drives on coil rack and the block and moves, get out of the way thimble, thimble is pressed in the thimble groove by eedles, and it is porose that this state is equivalent to card; When feeding reversing the current in the coil, coil drives block and moves down, and block blocks thimble, and eedles can not be pressed into thimble the thimble groove, and this state is equivalent to the card atresia.

Fig. 3 is a working state schematic representation of the present utility model.

The specific embodiment

A kind of jacquard electronic needle selection mechanism for jacquard, comprise support 1, coil rack 4, permanent magnet pieces and thimble 8, have on the support 1 magnet film trap 2 and with the thimble groove 7 of magnet film trap vertical direction, two permanent magnet pieces 3, permanent magnet pieces 6 end separately inserts respectively in the magnet film trap 2, the other end is all unsettled, the polarity of two permanent magnet pieces free ends is identical, and two permanent magnet pieces are concentric, coil rack 4 is enclosed within two permanent magnet pieces 3, on the free end of permanent magnet pieces 6, can slide up and down at permanent magnet pieces, coil rack is wound with coil 5 on 4 outsides, and an end of coil rack 4 is provided with block 9.

Among Fig. 2, when feeding forward current in the coil 5, the coil top produces S utmost point below and produces the N utmost point, the N utmost point that is subjected to magnetic sheet is then inhaled mutually with the S utmost point, and the S utmost point and the S utmost point repel each other, and makes coil 5 upwards, the N utmost point of below is inhaled mutually with the S utmost point of following permanent magnet pieces 6, and the N utmost point of the N utmost point repels each other, and propelling coil 5 makes progress, and four power move upward coil rack 4.

On the contrary, when feeding reversing the current in the coil 5, as shown in Figure 3, coil top produces N utmost point below and produces the S utmost point, and then the top N utmost point and the N utmost point that are subjected to magnetic sheet repels each other, and the S utmost point is inhaled mutually with the N utmost point, make coil downward, the S utmost point of below repels each other with the S utmost point of following permanent magnet pieces 6, and the S utmost point is inhaled mutually with the N utmost point, propelling coil 5 is downward, and four power move downward coil rack 4.Thereby this mechanism's strength is bigger more stable and volume is littler.

Claims

1, a kind of jacquard electronic needle selection mechanism for jacquard, comprise support, coil rack, permanent magnet pieces and thimble, it is characterized in that: have on the support magnet film trap and with the thimble groove of magnet film trap vertical direction, two permanent magnet pieces end separately inserts respectively in the magnet film trap, the other end is all unsettled, the polarity of two permanent magnet pieces free ends is identical, and two permanent magnet pieces are concentric, coil rack is enclosed within on the free end of two permanent magnet pieces, be wound with coil on the coil rack, an end of coil rack is provided with block.
