The specific embodiment
The electronic jacquard that the utility model can form three warp thread positions selects yarn feeding device, and it is mainly separated the electronic jacquard that supports by several by side stand and medium-height trestle and selects the yarn unit to form.Each electronic jacquard selects the yarn unit to comprise a medium-height trestle, two identical, repeatedly put the electromagnet that together can work respectively and be fixed on the medium-height trestle both sides, four magnetic conduction swing arms lay respectively at the both sides of two electromagnet, one end of each magnetic conduction swing arm has an electromagnet armature to match with electromagnet, the other end has a Jian Zui to match with a drag hook, drag hook moves up and down with griffing under the effect griffing, two magnetic conduction swing arms of same electromagnet drive a fixed pulley group of being made up of two movable pulleys by rope, two running blocks are by a fixed pulley contact, plane, fixed pulley place is vertical with plane, electromagnet place, by the cooperation of two running blocks and a fixed pulley, realize three warp thread positions.Four magnetic conduction swing arms are controlled respectively by two electromagnet in couples and are fixed or do not fix four drag hooks, the rotation of paired magnetic conduction swing arm can not cause the distortion of self and selected mobile drag hook about two electromagnet, and this can be avoided the mechanical fatigue of these parts.
Below in conjunction with drawings and Examples the utility model is described in further detail, it is more obvious that the purpose of this utility model and effect will become.
As shown in the figure, the electronic jacquard that the utility model can form three warp thread positions selects yarn feeding device mainly to select the yarn unit to form by the electronic jacquard that several separate support by side stand and medium-height trestle (not shown). wherein, each electronic jacquard selects the yarn unit to comprise: medium-height trestle 1, two electromagnet 2,20, two pairs of magnetic conduction swing arms 3,23, two pairs of drag hooks 4,25, four movable pulleys 9,10,11,12, three ropes 7,8,13, fixed pulley 14,16. two electromagnet 2 of fixed block 15 and snap joint, 20 are separately fixed at medium-height trestle 1 both sides, two pairs of magnetic conduction swing arms 3,23 are enclosed within on the bearing pin 22 of medium-height trestle 1 head, lay respectively at two electromagnet 2,20 both sides. every pair of magnetic conduction swing arm 3, an end of 23 has a pair of electromagnet armature 17,21 with corresponding electromagnet 2,20 match, the other end has a pair of sharp mouth 19,24 with drag hook 4,25 cooperate, magnetic conduction swing arm 3,23 with electromagnet 2, be connected with spring 6 between 20, spring 6 is used for promoting magnetic conduction swing arm 3,23. four movable pulleys 9,10,11,12 by two running blocks of support 29 compositions, respectively by rope 7,8 and two pairs of drag hooks 4,25 link to each other. and the 3rd rope 13 is with fixed block 15, two running blocks, fixed pulley 14 and snap joint 16 polyphones get up. and fixed block 15 is fixed on the medium-height trestle 1, fixed pulley 14 also is fixed on the medium-height trestle 1, fixed pulley plane, 14 place and movable pulley 9,10,11, plane, 12 place is vertical.
Specifically, first movable pulley 9 and second movable pulley 10 are formed a running block, the 3rd movable pulley 11 and the 4th movable pulley 12 by support 29 and are formed a running block by support 29.First rope 7 is walked around first movable pulley 9, and two links to each other with two drag hooks of first pair of drag hook 4.Second rope 8 is walked around the 3rd movable pulley 11, and two links to each other with two drag hooks of second pair of drag hook 25.The 3rd rope 13 is walked around the 4th movable pulley 12, fixed pulley 14 and second movable pulley 10 successively, and two links to each other with snap joint 16 with fixed block 15 respectively.
As shown in Figure 1, when electromagnet 2,20 is not switched on work, mobile armature 17,21 under spring 6 effect away from the iron core of electromagnet 2,20.As shown in Figure 2, when electromagnet 2,20 energising work, the electromagnetic force of its generation is greater than the elastic force of spring 6, and the electromagnetic force elastic force that overcomes spring guarantees that mobile armature 17,21 is in binding site like this.
Fig. 3 shows operation principle of the present utility model, and in resting position, electromagnet 2,20 is not worked, and under the effect of spring 6, magnetic conduction swing arm 3,23 is promoted along the direction that makes drag hook 4,25 near the device center line, as shown in Figure 1.
When drag hook 4,25 during near its orbit centre upper dead center position, be positioned at the drag hook top 18,28 on drag hook 4,25 tops, because the inclined-plane of its conical in shape and sharp mouth 19,24 outer surfaces, top 18,28 is pushed sharp mouth 19,24 open and is made its center line away from device, when sharp mouth 19,24 is pushed on top 18,28 open, promote the electromagnet armature 17,21 of magnetic conduction swing arm 3,23 upper ends and contact with iron core 26,27 on the electromagnet 2,20.At this moment, electromagnet 2,20 can be worked or not work, as shown in Figure 2.
With a side griffe 5 the motion be example, as the device right side griffe 5, below described every pair of magnetic conduction swing arm 3,23, drag hook 4,25, electromagnet armature 17,21 in the magnetic conduction swing arm 3,23 and drag hook 4,25 all refer to the corresponding single part on right side among Fig. 3.
When electromagnet 2,20 no power whens work all, spring 6 is pushed magnetic conduction swing arm 3,23 open, 18,28 sharp relatively mouth 19,24 motions of drag hook top, the result makes sharp mouth 19,24 be fixed on the top 18,28 of drag hook 4,25, drag hook 4,25 is fixed on top dead center position on its track by sharp mouth 19,24, as the left hand view of Fig. 2.After the descending motion, if griffe 5 upwards push-and-pull hook 4,25 it is thrown off from sharp mouth 19,24, drag hook 4,25 remains on position shown in Fig. 3 (a) always.This moment, pulley 9,10,11,12,14 and rope 7,8,13 were all at original invariant position, shown in Fig. 3 (a).
When the 20 energising work of second electromagnet and first electromagnet 2 were not worked, electromagnet armature 21 overcame the elastic force of spring 6, abuts against on first iron core 26, shown in Fig. 2 right part of flg.Drag hook 25 descends and griffes 5 to engage from upper dead center position.This moment, first movable pulley 9 and second movable pulley 10 were still in situ constant, and the 3rd pulley 11 and the 4 12 simultaneously to bottom offset distance H, because the motion principle of movable pulley, make the snap joint 16 of the 3rd rope 13 lower ends walk around second pulley 10, the 4th movable pulley 12 and fixed pulley 14 in succession to bottom offset height 2H, reach position as Fig. 3 (b).
When first electromagnet 2 and second electromagnet 20 were switched on work simultaneously, electromagnet armature 17,21 overcame the elastic force of spring 6 simultaneously, abuts against on the iron core 27,26 of electromagnet 2,20.Drag hook 4,25 all descends from the top dead center position and griffes 5 to engage.This moment first movable pulley 9 and second movable pulley 10 to bottom offset distance H, the 3rd movable pulley 11 and the 4th movable pulley 12 also to bottom offset distance H, because the motion principle of movable pulley, therefore the snap joint 16 of the 3rd rope 13 lower ends of walking around second movable pulley 10, the 4th movable pulley 12 and fixed pulley 14 in succession to bottom offset apart from 2H+2H, be 4H, reached the position shown in Fig. 3 (c).
Therefore, electronic jacquard of the present utility model selects yarn feeding device can obtain three kinds of positions of snap joint in shown in Figure 3, compares with the former yarn feeding device that selects, and shed opening has realized increase at double, the warp thread position of also having realized three kinds of differing heights simultaneously.It is quite reliable that equipment the utility model electronic jacquard selects the weaving system of yarn feeding device to turn round under high speed, and power consumption is lower.Can be used for producing special fabric, particularly as plain velvet fabric or carpet.
