Device for controlling sinker to be opened and closed and full-automatic computerized flat knitting machine adopting device

Abstract

The invention relates to a device for controlling a sinker to be opened and closed. The device comprises a bottom plate, a left sliding triangle component, a right sliding triangle component, a gear, a rack cam, a left sliding block and a right sliding block. The left sliding triangle component and the right sliding triangle component are arranged in a first long circular groove in the bottom plate in parallel. The gear is engaged with the rack cam. The rack cam is provided with a groove, and rollers drive the left sliding triangle component and the right sliding triangle component to slide up and down along the first long circular groove during sliding. The left sliding block and the right sliding block are installed on the bottom plate through pins, when the rack cam moves leftwards and rightwards, the left sliding block or the right sliding block is pressed by the rack cam, and then one time of closing action of the sinker is achieved. The rack cam moves linearly leftwards and rightwards in a reciprocating mode to press the left sliding block or the right sliding block, the re-closing action is added based on original action of the sinker, the closing-opening-closing motion trail is formed, it is guaranteed that old thread loops are not taken up after a knitting needle returns to the original position, and looping and loop transferring quality is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of fully automatic computerized flat knitting machines, in particular to a device for controlling the opening and closing of sinkers and a fully automatic computerized flat knitting machine. Background technique [0002] The power for opening and closing of the sinker comes from the sinker control device installed on the head of the automatic computerized flat knitting machine. The gear installed on the stepping motor drives the rack cam to realize reciprocating motion, and then drives the left and right sliding triangle components to control The opening and closing action of the sinker realizes the holding and pulling effect on the coil forming coil or the coil stripping coil. [0003] When the knitting needle rises with the knitting triangle assembly to complete the knitting, the sinker installed on the weaving mouth of the front and rear needle beds starts to close gradually through the above-mentioned sinker contr...

Problems solved by technology

[0004] Yet, the biggest drawback that exists in this sinker opening and closing device at present is: after the hook on the knitting needle finishes feeding new yarn, the sinker It is always in the process of opening. When the new loop is being looped and pulled down, it is easy to bring up the old loop in the weaving mouth, causing the old loop to float up, which affects the quality of knitting needle looping and loop transfer.
