Lifting yarn nozzle

The technical field is as follows:

the utility model belongs to the technical field of spinning machine, in particular to over-and-under type yarn mouth.

Background art:

the existing full-computerized flat knitting machine mostly adopts computer signals to control a yarn nozzle to start working or stop working at any place in a knitting width range, for example, the inventor proposes a ZL201410218898.X Chinese invention patent in advance, and discloses a control system and a control method of a self-running yarn nozzle of the flat knitting machine, the self-running yarn nozzle system and the control method of the flat knitting machine provided by the invention have the advantages that the position control is accurate, the phenomena that the yarn nozzle cannot hook the yarn, the yarn is hooked and staggered, and even the knitting needle can be damaged due to the deviation of the yarn nozzle parking position are avoided, and the running safety of the equipment is ensured; and the accurate parking of the yarn nozzle makes some special processes easier to realize; the number of the yarn mouths can be increased or decreased at will, the expansion adaptability is strong, and the use is convenient.

However, compared with the yarn feeder of the flat knitting machine, the self-running yarn feeder has the advantages that the operation of the yarn feeder is more accurate, quicker and more efficient, but the adjustment is more difficult when the yarn feeder weaves more complicated patterns.

The utility model has the following contents:

the utility model aims at providing a yarn mouth that can go up and down to adjust.

The utility model adopts the technical scheme as follows:

an elevating yarn feeder, comprising:

the lower part of the yarn nozzle sliding block is connected with a yarn nozzle rod, and the yarn feeding nozzle is arranged at the lower part of the yarn nozzle rod;

a drive mechanism comprising:

the pressing wheel is used for converting the power of the head motor into downward driving force;

the first driving block is made of rigid materials, is arranged in a sliding groove on the yarn feeder sliding block and is connected with the pressing wheel;

the second driving block is made of flexible materials, is arranged in the first sliding groove on the yarn nozzle rod and is connected with the first driving block;

the sliding block is arranged in a second sliding groove on the yarn nozzle rod and is connected with a second driving block;

one end of the reset unit is arranged on the first driving block, and the other end of the reset unit is arranged on the yarn nozzle sliding block.

The further setting is that:

the reset unit is a spring.

The first sliding groove and the second sliding groove are communicated into a whole.

The first driving block is made of cast iron, stainless steel or aluminum alloy.

The second driving block adopts an adhesive tape or an adhesive tape.

The second driving block adopts an adhesive tape with a steel wire core.

The yarn nozzle rod is made of flexible materials.

The yarn mouth rod adopts any one of adhesive tapes or adhesive tapes.

The yarn feeding nozzle is connected with the sliding block;

the working principle of the utility model is as follows:

(1) unique yarn nozzle lifting mechanism design:

from the slider of running formula yarn mouth make reciprocating motion back and forth along flat-bed machine guide rail, when needs weave complicated flower type, through the drive of flat-bed machine aircraft nose motor, the pinch roller is pushed down by aircraft nose motor, under the effect of pinch roller, first drive block slides down along the spout, compression spring, and then drive second drive block, the slider, thereby the drive send yarn mouth downstream to assigned position, accomplish and send the yarn back, the aircraft nose motor further motion, break away from the pinch roller, at this moment, spring action, actuating mechanism upward movement, the drive sends yarn mouth upward movement and accomplishes the restoration.

(2) The utility model discloses a drive mechanism that rigidity and flexibility combined together:

the existing yarn feeder lifting mechanism mostly adopts a rigid driving mechanism, for example, the Chinese patent of CN201811112886.3, adopts a motor, a gear and a rack to drive the yarn feeder to complete the lifting motion, and the rigid driving mechanism still easily causes the contact and collision among the yarn feeders when the yarn feeders of the flat knitting machine are linearly distributed.

The utility model discloses a drive mechanism that rigidity and flexibility combined together, through the aircraft nose motor of flat-bed machine promptly, the drive pinch roller, pinch roller compression spring drive earlier and set up first drive block (rigidity) in the yarn mouth slider, under the effect of first drive block, second drive block (flexibility) of redriving yarn mouth slider below to the drive slider drives and send the yarn mouth to push down. Therefore, the second driving block for driving the yarn feeding nozzles can generate certain deformation while driving is completed, and therefore contact and collision caused by the layout problem of the yarn feeding nozzles among multiple groups of yarn feeding nozzles can be avoided.

The following detailed description is made with reference to the accompanying drawings and embodiments of the present invention.

Description of the drawings:

fig. 1 is a schematic assembled structure of the present invention;

fig. 2 is a schematic structural diagram of the lifting driving mechanism of the present invention.
