Description

Sock suction pipe assembly moving mechanism in sock machine Technical Field The invention belongs to the technical field of knitting machinery, and particularly relates to an integrated intelligent hosiery machine, in particular to a sock suction pipe assembly moving mechanism in the hosiery machine. Background After the sock is knitted, the sock needs to be sewn, namely, the toe part of the sock is sewn and sealed. In the technology of automatic sock sewing, the main technical scheme is published in China patent No. 2009801088587. The circular knitting machine represented by the patent comprises an upper part and a lower part which are respectively arranged above and below a middle area, wherein the middle area is provided with a device for supporting and hanging socks, after the socks enter a sock suction pipe assembly at the lower part, the sock suction pipe is inserted upwards to pass through the unsealed socks to reach the upper part, the socks are outwards turned outside the sock suction pipe, and then the stitching operation is carried out, so that the socks enter the sock suction pipe better, and the sock suction pipe assembly has an inclined action relative to the vertical direction. On this basis, many improvements have been made by those skilled in the art in order to allow longer socks to enter the sock tube smoothly. For example, publication number CN107345336A, CN208201288U, CN109576884a, they have the common feature that the lower assembly (i.e. sock suction tube assembly) has a track, which can move it to a more advantageous position, and then cooperate with the technical features of negative pressure, up-down movement, etc. of the sock suction tube, so that the sock can enter the sock suction tube earlier and faster. For example, the publication CN113943999a, the sock is drawn back by negative pressure for many times to make the sock enter the sock sucking tube, so that the sock can be suitable for a relatively long sock. In all the prior art, the sock suction tube assembly needs to integrally make a certain movement as one assembly, or make an inclination angle rotation, or make a translation along the track up and down and left and right, or a combination of the two movements, and in general, the movement of the sock suction tube assembly is performed on a plane. We have found that the motion of the sock tube assembly in the prior art is in a two-dimensional plane of x-axis and y-axis and does not involve motion in the z-axis direction, from the perspective of an observer standing in front of the machine, with the left-right direction being defined as the x-axis, the up-down direction being defined as the y-axis, and the front-back direction being defined as the z-axis. However, with the development of technology, more and more additional components on the stocking machine inevitably occupy more and more space, and the movement plane of the stocking pipe assembly just blocks part of the installation space in front of the stocking machine, and if other components are arranged in the installation space, movement interference can be generated with the stocking pipe assembly. Disclosure of Invention The invention aims to provide a sock suction pipe assembly moving mechanism in a sock machine, which has a more reasonable moving path and can release a space in front of the sock machine.
