Inker cam device capable of freely ascending, descending and moving leftwards and rightwards

Abstract

The invention relates to a sinker cam device capable of freely ascending, descending and moving leftwards and rightwards. The sinker cam device comprises a base plate, a sinker cam, a guide supporting plate, a pulling plate and a lifting sliding block. A pulling plate groove and a lifting sliding block groove are formed in the base plate; the pulling plate is installed in the pulling plate groove, the lifting sliding block is installed in the lifting sliding block groove, the pulling plate moves left and right to drive the lifting sliding block to ascend and descend up and down, sedimentation ascending and descending synchronously ascend and descend along with lifting sliding, in addition, the guide supporting plate can move left and right, and meanwhile, the guide supporting plate is connected with the sinker cam and can drive the sinker cam to move left and right. According to the invention, the sinker cam can be lifted and can further translate left and right, when a machine head moves leftwards, the sinker cam moves rightwards to the rightmost end and simultaneously moves to the lowest position, the normally-closed sinker is opened, so that a coil slides down to a looping position to form a tissue, and when the machine head moves rightwards, the sinker cam moves leftwards to the leftmost end and simultaneously moves to the highest position, and at the moment, the normally-closed sinker is closed to press the yarn.

Description

technical field [0001] The invention relates to the technical field of computerized flat knitting machines, in particular to a sinking cam device capable of freely moving up and down and left and right. Background technique [0002] The sinker mechanism in the computerized flat knitting machine is used to press the knitted fabric in the process of knitting downward to assist the knitting needle to withdraw the loop. The sinker of the two needle beds can be rotated and opened relative to the needle bed opening to make room for knitting. , which is beneficial for closing, bending, looping and pulling during the weaving process. The sinker mechanism usually mainly includes two parts: the sinker and the sinker assembly. The sinker presses down the yarn or lifts and loosens the yarn by using the sinker assembly to drive the sinker. [0003] Sink components include a sinker cam, which acts on the sinker by moving left and right, causing the sinker to rotate, thereby lifting and r...

Problems solved by technology

For example, the patent with the publication number CN212611184U discloses a sinker and sinker mechanism for flat knitting machines. The sinker mechanism in this patent includes a Sink assembly, and the middle Sink triangle in the Sink assembly can move left and right, but cannot be raised or lowered. When moving, when the needle is shoveled, the local loop is hung on the knitting needle for a long time when it is knitting in other parts, waiting for the next action. At this time, when the middle Xinke triangle passes through this part and waits for the loop, it is not necessary to make the sinker happen. action, but because the middle Xinke triangle cannot be lifted, it will make the normally closed sinker on the waiting coil do unnecessary opening and closing actions, causing the coil to be squeezed and pulled many times, and the yarn is easy to break, affecting the fabric quality, therefore, it is necessary to improve and optimize it
