Description
Technical Field
The invention relates to the technical field of knitting equipment, in particular to a yarn nozzle disc lifting anti-winding device for a hosiery machine.
Background
With the continuous development of industrial automation technology, the field of hosiery knitters gradually develops towards automatic sock-sewing heads (sock-sewing and sock-head-sewing integrated hosiery machines). When snatching socks and make up the undertoe in automatic integrative hosiery machine of margin to seam, must lift yarn mouth dish and make grabbing device get into hosiery machine and weave the cylinder top, thereby can cause the yarn to relax and appear near yarn intertwine, hang spare part on the yarn mouth dish or curl by oneself and phenomenon such as knot at yarn mouth dish in-process that rises, yarn mouth dish decline and can cause the broken yarn phenomenon when getting into the circulation of weaving next time once more to greatly reduced hosiery machine and woven efficiency and weave the yields. The problem of yarn winding caused by the lifting of the yarn nozzle disc is not an effective solution so far, thereby restricting the development of the automatic head sewing integrated hosiery machine.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a yarn nozzle disc lifting anti-winding device for a hosiery machine, which can effectively control the yarn loosening phenomenon in the lifting process of the yarn nozzle disc, enables the yarn to be always kept in a tensioning state, does not extend the length of the yarn at two threading points, and has simple structure and convenient control.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a yarn nozzle dish goes up and down to prevent kinking device for hosiery machine, includes the swing arm and keeps the piece, follows the circumference that the swing arm keeps the piece is to articulated having a plurality of tensioning swing arms, the lower extreme of tensioning swing arm leans out the setting, the below that the swing arm keeps the piece is equipped with the elevator control dish with yarn nozzle dish subassembly fixed connection, the lower part of tensioning swing arm with elevator control dish sliding connection, tensioning swing arm bottom is equipped with a plurality of through-holes that supply the yarn to pass.
Every tensioning swing arm corresponds yarn mouth setting all the way, and the swing arm keeps the piece to be fixed in the creel upper end through the creel spliced pole, and the bottom and the yarn mouth dish subassembly of lift control dish are connected, and the lower extreme of tensioning swing arm leans out the setting, becomes certain oblique angle for lift control dish's rising direction. The yarn vertically penetrates through the electric eyelet porcelain ring hole at the upper end of the creel, firstly penetrates through the through hole at the lower end of the yarn tensioning swing arm, and then penetrates through the yarn nozzle hole on the yarn nozzle disc component. When the yarn nozzle disc assembly rises, the distance between the yarn nozzle disc and the electric eye is shortened, the lifting control disc rises to slide along the tensioning swing arm at the moment, so that the tensioning swing arm swings outwards, the shortened distance between the yarn nozzle disc assembly and the electric eye is just compensated, the original tension of the yarn is always kept, and the problem of yarn winding caused by the rising of the yarn nozzle disc assembly is effectively solved. The yarn nozzle disc component descends, the distance between the yarn nozzle disc and the electric eye returns to the initial state, at the moment, the lifting control disc loses acting force on the yarn tensioning swing arm, the yarn tensioning swing arm swings back to the original position along with the action of gravity, the yarn returns to the initial vertical threading state, and the smooth passing of the yarn during weaving is not influenced.
Furthermore, a first through groove and a second through groove for the tensioning swing arm to pass through are respectively formed in the circumferential direction of the swing arm retaining block and the circumference direction of the lifting control disc. The tensioning swing arm keeps the swinging direction in the first through groove, the lower section of the tensioning swing arm is inserted into the second through groove of the lifting control disc, and the lifting control disc slides along the tensioning swing arm through the second through groove to further limit in the ascending or descending process.
Furthermore, a swing arm clamping block is arranged above the swing arm retaining block, a fixing ring is arranged between the swing arm retaining block and the swing arm clamping block, and a rotating hole for the fixing ring to pass through is formed in the top end of the tensioning swing arm. The swing arm clamping block is fixed above the swing arm retaining block through screws, the swing arm fixing ring is clamped in the middle and fixed, the fixing ring penetrates through a rotating hole formed in the upper end of the tensioning swing arm, and the tensioning swing arm can rotate and swing in a first through groove of the swing arm retaining block by taking the rotating hole as a fulcrum.
Furthermore, a plurality of through grooves III corresponding to the through grooves I are formed in the circumferential direction of the swing arm clamping block, and the swing arm can be further guided and tensioned by the swing arm retaining block through the through grooves III.
Further, the fixing ring is a steel wire ring.
Furthermore, the tensioning swing arm comprises a first connecting section and a second connecting section which are fixedly connected, the first connecting section is arranged along the vertical direction, and the connecting sections are arranged in an outwards inclined mode. In the process that the yarn nozzle disc component rises, the lifting control disc rises to drive the tensioning swing arm to swing outwards, so that the occupied space of the tensioning swing arm can be increased, the upper end connecting section is vertically arranged, the outward-expanding occupied space of the tensioning swing arm can be reduced, and the structure is compact.
Furthermore, the first connecting section and the second connecting section are designed to be integrally formed.
Furthermore, the bottom of the second connecting section is provided with a horizontal plate, the through hole is formed in the horizontal plate, and a porcelain ring is installed in the through hole.
Furthermore, the lifting control disc is connected with the yarn nozzle disc assembly through a connecting support, the upper end face of the connecting support is fixedly connected with the lifting control disc through screws, and the lower end of the connecting support is fixedly connected with the yarn nozzle disc assembly through screws, so that the lifting control disc is connected with the yarn nozzle disc assembly and can lift along with the yarn nozzle disc assembly.
In conclusion, the yarn nozzle disc is opened outwards by the tensioning swing arm in the lifting process, so that the yarn is always kept in a tensioning state, and the yarn is prevented from being loosened; when the yarn nozzle disc descends to return to the initial knitting state, the yarn keeps vertical and smooth, the yarn conveying resistance is not increased, and the continuous hosiery knitting is not influenced.
