Sinker control device of sock knitting machine

Abstract

The invention relates to a sinker control device of a sock knitting machine. The sinker control device comprises a sinker cover, a plurality of control units arranged on the sinker cover and a plurality of drive units arranged on the sinker cover and used for linking the control units, wherein the sinker cover is provided with an annular groove and a plurality of guide slot sets; and each controlunit is provided with a first control piece and a second control piece, the first control piece is provided with two guide pins inserted in the guide slot sets and two guide parts, and the second control piece is provided with two sliding guide parts mutually sleeved with the guide parts. The first control pieces are respectively driven by utilizing the drive units to displace along the annular direction, therefore a gap between the control units and the annular groove can be changed, and the purposes of accurately controlling the stroke of the pieces and improving the quality of knitted socks are reached.

Description

technical field [0001] The invention relates to a hosiery machine, in particular to a squeegee control device of the hosiery machine. Background technique [0002] Such as figure 1 As shown, there is an existing sham control device for a hosiery machine (China Taiwan certificate number M306592 case), which includes a body 1, two control sheets 2 and two drive units 3, and the body 1 has a bottom concave The ring groove 101 provided, the control piece 2 is L-shaped, each has a shaft connection portion 201 pivotally arranged in the ring groove 101, a stop portion 202 extending to the outer peripheral surface of the body 1, and an arc-shaped The guiding part 203 and the driving unit 3 each have a pneumatic element 301 and a driving rod 302 driven by the pneumatic element 301 to produce a telescopic movement. Using the pneumatic element 301 to drive the driving rod 302 to extend or retract, can drive the stop part 202 of the control piece 2 to pivot with the pivot joint 201 as...

Problems solved by technology

[0003] Although this kind of slush control device can achieve the expected operation purpose, it can be seen from the solid line and the imaginary line of the control sheet 2 that the guide part 203 will be different under the different states of the solid line or the imaginary line. Making the corresponding part of the guide part 203 have unequal diameters relative to the center point of the body 1 will result in inaccurate movement of the sack, that is, one end of the guide part 203 relative to the body 1 The center point is narrow, and the other end is wider than the center point of the main body 1, which will make the corresponding wider part of the raw gram sheet easily moved outward by centrifugal force, resulting in affecting the quality of hosiery knitting
