Description
Technical Field
The utility model relates to the field of computerized flat knitting machines, in particular to a sinker of a flat knitting machine and a control structure thereof.
Background
The computerized flat knitting machine is a double-needle-plate latch needle weft knitting machine, the triangular system of the computerized flat knitting machine is just like a group of plane cams, the stitches of knitting needles can enter the channels of the cams, the triangular system is moved to force the knitting needles to do regular lifting motion in the needle grooves, and yarns can be knitted into knitted fabrics through the actions of needle hooks and needle latches. In the ascending process of the knitting needle, the loop gradually withdraws from the needle hook, opens the needle latch, and withdraws from the needle latch to be hung on the needle rod; in the descending process of the knitting needle, the needle hooks hook the newly laid yarn and pull and bend the newly laid yarn into loops, meanwhile, the original loops are separated from the needle hooks, the new loops pass through the old loops and are connected with the old loops in series, and a plurality of loops formed by knitting are connected with each other to form the knitted fabric.
In the existing flat knitting machine, the sinker only plays an auxiliary role when knitting loops, the downward pressure of the loops is mainly the pulling force acting on the fabric by the roller or the bottom plate, the knitting needle is not independently matched with the knitting capacity, the cloth piece is pulled down by the roller, a section of waste yarn needs to be knitted in advance as an acting point of the roller, the section of waste yarn needs to be treated after knitting is finished, and the production cost is also increased.
In the prior patent CN211471740, a sinker is disclosed, which has the function of directly knitting a cloth piece to press down and pull down the cloth piece without waste yarn, but the sinker has small swing amplitude and single control structure, and still has certain defects.
Accordingly, the present inventors have further studied this, and developed a sinker of a flat knitting machine and a control structure thereof, which have been produced thereby.
Disclosure of Invention
The utility model aims to provide a sinker of a flat knitting machine and a control structure thereof, so that the sinker has better independent knitting needle looping capacity.
In order to achieve the above object, the technical scheme of the present utility model is as follows:
sinker of a flat knitting machine comprising
A supporting part which is a rotation fulcrum of the sinker;
a butt part, which is positioned at one side of the supporting part;
the wire pressing part is positioned at the other side of the supporting part and is of an arc-shaped structure as a whole, a pressing tooth is arranged on the outer arc edge of the wire pressing part, and a wire blocking arc edge is arranged on one side of the pressing tooth;
the whole butt part from the supporting part to the thread pressing part is in an L-shaped or J-shaped structure.
A sinker control structure of a flat knitting machine comprises the sinker, a front sinker cam and a rear sinker cam;
the front settlement triangle acts between the supporting part and the line pressing part to enable the line pressing part to be pressed downwards;
the rear settlement triangle acts on the butt part and is used for pressing the butt part downwards to enable the thread pressing part to be lifted.
Through the structure, the sinker can have larger lifting or pressing amplitude, the pressing teeth can simultaneously perform the functions of drawing cloth or pressing yarn, the loop is prevented from being taken off, and the arc-shaped part can play a role of giving way without disturbing the yarn.
Further, the sinker is provided with a limiting pit or a limiting radian at the position corresponding to the positions acted by the front sedimentation triangle and the rear sedimentation triangle.
The limiting mode is based on that the sedimentation triangle can push the sedimentation piece to lift.
Further, the supporting part is a semicircular structure, and a abdication pit is arranged between the supporting part and the line pressing part.
The sinkers are generally arranged on spacers, and the relief pits are matched with the spacers to limit the swing amplitude of the sinkers.
Further, the thickness of the pressing line portion is smaller than that of the other portions.
A step is arranged between the line pressing part and the supporting part, so that the thickness of the line pressing part is smaller than that of other parts, and the thinned part is used for giving way to the spacing piece.
After the scheme is adopted, compared with the prior art, the utility model has the following advantages:
through the scheme, the independent knitting needle looping capacity of the sinker is realized, and the roller or the lifting plate is not required to provide tension, so that no waste yarn is generated when the fabric is started, and the structure is more reasonable than the design of the existing structure.

Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
As shown in fig. 1, a sinker of a flat knitting machine includes a pressing line portion, a supporting portion 11, and a butt portion 12, each sinker 1 corresponds to one spacer 4, the supporting portion 11 is disposed on the spacer 4, and is a rotation fulcrum of the sinker 1, a semicircular structure is disposed below the supporting portion 11, a yielding pit 14 is disposed between the supporting portion 11 and the pressing line portion 13, and the yielding pit 14 is matched with the spacer 4 to limit the swing amplitude of the sinker 1.
The butt portion 12 is located the left side of supporting part 11, and the line ball portion 13 is located the right side of supporting part 11, and butt portion 12 wholly is J-shaped structure through supporting part 11 to line ball portion 13, and line ball portion 13 wholly is the arc structure, is provided with on the outer arc edge of line ball portion 13 and presses tooth 131, presses tooth 131 one side to be provided with fender line arc limit 132, presses the tooth to be used for pressing yarn or granny rag, keeps off line arc limit can not cause the interference to the yarn when the sinker swings.
The butt portion 12 is relatively flat as a whole, and the junction between the butt portion 12 and the support portion 11, and between the presser portion 13 and the support portion 11 is an action point of the sinking triangle. The thickness of the pressing line part 13 is smaller than that of other parts, and a step 15 is arranged between the pressing line part 13 and the supporting part 11, so that the thickness of the pressing line part 13 is smaller than that of other parts, and the thinned parts are used for giving way to the spacing pieces 4.
