The specific embodiment

The utility model is mainly by flanged 11 mount pad 10, place the push rod 1 on the mount pad 10, footstock 3, doff electromagnet 2, tension spring pin 6, the pinch roller seat 8 of band pinch roller 14, the yarn detector seat 12 of the band photoelectricity yarn detector 13 and the electromagnet 9 that doffs, the handle 4 that connects push rod 1 and footstock 3, the pull bar 5 of connection push rod 1 and pinch roller seat 8 places the formations such as extension spring 7 between tension spring pin 6 and the pinch roller seat 8.

During use, the utility model is installed between the friction roller 16 and delivery roller 17 of rotor spinning machine, the flange 11 of band mount pad 10 is installed on the wallette plate 25 of rotor spinning machine and clamps fixing by fixture block 18, push rod 1, footstock 3, pinch roller seat 8 usefulness bearing pins are installed on the mount pad 10, block with back-up ring, rotate flexibly, handle 4 usefulness bearing pins connect footstock 3 and push rod 1, pull bar 5 usefulness bearing pins connect push rod 1 and pinch roller seat 8, tension spring pin 6 is installed on the mount pad 10 and blocks with back-up ring, 7 one of extension springs connect tension spring pin 6, an other connection pinch roller seat 8, pinch roller 14 is installed on the pinch roller seat 8 and is screwed, and visits silk device seat 12 and is screwed on mount pad 10, electromagnet 9 and the photoelectricity spy silk device 13 usefulness screws that doff are installed in to be visited on the silk device seat 12, and doff electromagnet 2 usefulness screws are installed on the mount pad 10.

The utility model is a cover lever connecting rod mechanism, by the motion transmission of a succession of lever connecting rod, realizes normally two duties such as spinning, joint preparation.During normal the spinning, guarantee that push rod 1 and yarn tube 15 have certain interval, 17 of pinch roller 14 and delivery rollers keep normal pressure simultaneously.During the joint SBR, push rod 1 holds up yarn tube 15, makes yarn tube 15 and friction roller 16 that certain interval be arranged, pinch roller 14 breaks away from delivery roller 17, with delivery roller 17 interval 6mm, footstock 3 is compressed into the iron core on the doff electromagnet 2 simultaneously, and iron core is held by doff electromagnet 2.When carrying out joint by lower contact button 20, at first feed roller 22 is given cotton; Behind the time-delay certain hour, the electromagnet 9 energising actions of doffing, heavy yarn begins, behind the time-delay certain hour, 2 outages of doff electromagnet, iron core resets under the effect of spring and promotes footstock 3, triggers the sleeve mechanism action, realizes that pinch roller 14 and yarn tube 15 fall, and finish joint.

During joint, carry out according to the following steps:

1, holds up spool stand 23.

2, touch the button 20, the feed roller 22 feeding small amount of fibers on the spinning organ.Keep the branch comb trigonum of " newly ", fiber loss, damage are lacked, 2 energisings of doff electromagnet.

3, press lower handle 4, push rod 1 lifts under the effect of each fixing point, pull bar 5 is depressed, pull bar 5 is depressed pinch roller seat 8, effect lower pressure wheel 14 at bearing pin also is lifted disengaging delivery roller 17, the iron core of doff electromagnet 2 is pressed in the electromagnet of energising under the effect of footstock 3, is held by electromagnet, and a whole set of linkage just is on the dead point.

4, open spinning organ 19, the revolving cup in the cleaning spinning organ 19 does not stay residual fiber, requires no-sundries in the revolving cup, and spinning organ 19 closes.

5 find out loose thread from yarn tube 15, pull out certain-length after, again spool stand 23 is put down yarn tube 15 is placed on the push rod 1 restfully.

6, yarn is successively walked around tension compensating bow 24, photoelectricity yarn detector 13, pinch roller 14, the iron core of the electromagnet 9 that doffs, the button 21 on the spinning organ 19, on the scale on the spinning organ, determined length of yarn (different technology, length of yarn also change to some extent).After length of yarn was determined, yarn laid out button 21, and the doffing tube outlet with the yarn loose thread is put into spinning organ 19 is sucked by spinning organ 19 negative pressure.

7, touch the button 20, feed roller 22 feeding slivers on the spinning organ 19, under electric control, doff and work behind the electromagnet 9 time-delay certain hours, iron core was inhaled in the electromagnet in moment, yarn falls down, effect yarn under working in negative pressure is inhaled in the revolving cup, also worked behind the doff electromagnet 2 time-delay certain hours, be pressed into the iron core in the doff electromagnet 2, ejected under the spring action in doff electromagnet 2, the iron core that footstock 3 is pressed in the doff electromagnet 2 flicks, a whole set of connecting rod has broken away from the dead point, under push rod 1 deadweight and extension spring 7 effects, hold pinch roller seat 8, make the pinch roller seat 8 other one a power of upwards lifting is arranged, promote push rod 1 by pull bar 5, push rod 1 is fallen down, broken away from yarn tube 15, yarn tube 15 drops on the friction roller 16 of rotation, and yarn tube 15 also begins rotation (coiling) under the effect of friction roller 16, handle 4 lifts under the effect of footstock 3 and push rod 1 simultaneously, pinch roller seat 8 is under the effect of extension spring 7, and pinch roller 14 and yarn have been pressed onto together on the delivery roller 17 of rotation, and then delivery roller 17 rotations of pinch roller 14, yarn is drawn out of in the revolving cup of rotation at a high speed, and joint is finished.
