Embodiment Construction
[0016] See Figures 1 to 4:
[0017] The present invention provides a yarn feeder automatic lifting mechanism, which includes a yarn feeder seat 1, a yarn feeder 2 is arranged on the lower part of the yarn feeder seat 1 to move up and down, and a yarn feeder push rod 3 is connected to the upper part of the yarn feeder 2, and the yarn feeder The function of the mouth push rod 3 is to provide a stressed position for the yarn feeder, and its shape and position can be set as required. In addition, the yarn feeder 2 is also connected with an elastic element (not shown) that exerts force upwards, and its function is to make the yarn feeder 2 return to its original position without external force. A pair of yarn feeder drivers 5 mounted on the same shaft 4 are arranged above the yarn feeder push rod 3 , and the shaft 4 is fixed to the yarn feeder seat 1 so that the yarn feeder drivers 5 can rotate around the shaft 4 . Yarn feeder driver 5 is constituted like this: it is formed by the...

A yarn feeder automatic lifting mechanism is provided, which comprises a yarn feeder arranged in the lower part of a yarn feeder holder in a way that the yarn feeder can move vertically; a yarn feeder pusher connected with the upper part of the yarn feeder; a pair of yarn feeder drivers coaxially arranged on the top of the yarn feeder pusher and formed by the coaxial superposition of a gear part and a cam part, wherein the outer edge of the cam part is larger than that of the gear part and is abutted against the yarn feeder pusher; a toothed bar connected with the top of the gear part and engaged with the gear part, a leaf yarn feeder holder guard strip and a right yarn feeder holder guard strip which are both arranged on the top of the yarn feeder holder and which respectively have a first bench and a second bench, the toothed bar being have a protrusion higher than the second bench; a slide rail on which the yarn feeder holder is movably arranged; and a toothed bar pusher which is arranged above the leaf and right yarn feeder holder guard strips and capable of moving along the slide rail and stretching or retracting vertically, wherein the width of the toothed bar pusher being smaller than the distance between the leaf and right yarn feeder holder guard strips. In the invention, the toothed bar pusher dives the toothed bar which in turn moves the yarn feeder driver to rotate and thus to move the yarn feeder, thereby realizing the automatic lift / fall of yarn feeder.
Description
technical field [0001] The invention relates to a knitting machine component, in particular to an automatic lifting mechanism for a yarn feeder. Background technique [0002] The yarn feeder of the knitting machine needs to be pushed down when it is working, and it needs to be lifted up when it is not working. In order to realize these two actions of the yarn feeder of the knitting machine, the existing mechanisms are very complicated and bulky. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic raising and lowering mechanism for the yarn feeder, which has a simple structure, small volume and can realize automatic lifting. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a kind of yarn feeder automatic lifting mechanism is provided, a yarn feeder is arranged at the bottom of a yarn feeder seat which can move up and down, the ...
