Needle allocation mechanism of flat knitting machine

Abstract

The invention provides a fashioning mechanism of a flat knitting machine, belonging to the technical field of knitting machinery. The mechanism comprises a pair of a first guide rail and a second guide rail, a pair of a first regulating block and a second regulating block, a pair of a third regulating block and a fourth regulating block, a shuttle box and a regulating block actuating device, wherein the first regulating block and the second regulating block are in sliding fit with the first guide rail; the third regulating block and the fourth regulating block are in sliding fit with the second guide rail; the shuttle box is in sliding fit with the first guide rail and the second guide rail; and the regulating block actuating device is arranged on a frame. The mechanism is characterized in that the regulating block actuating device comprises a cable pulley mechanism and a drive mechanism; the cable pulley mechanism is assembled on the first guide rail and the second guide rail, and is coupled with the first regulating block, the second regulating block, the third regulating block and the fourth regulating block; and the drive mechanism is arranged on the frame, is coupled with any one of the first regulating block, the second regulating block, the third regulating block and the fourth regulating block, and is matched with the side part of one end of the first guide rail or the second guide rail. The fashioning mechanism has the advantages that distance between the first guide rail and the second guide rail can be reduced, so as to ensure that volume of the flat knitting machine can be reduced, and the centered effect of the shuttle box can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, and in particular relates to a needle retracting and opening mechanism of a flat knitting machine. Background technique [0002] Chinese Utility Model Patent Authorization Announcement No. CN2576740Y discloses a needle retracting device for a flat knitting machine. The core of the patented technical solution is to install a lead screw on the frame, and design the respective threads of the two ends of the lead screw In contrast to each other, adjusting blocks are respectively arranged on the threads at both ends of the lead screw, and the adjusting block cooperates with the thread on the lead screw through its own internal thread, and the shuttle box (also called yarn guide shuttle) is set on a pair of adjusting between blocks. The above-mentioned technical scheme can conveniently set the moving range of the shuttle box, that is, it can only move between a pair of adjusting blocks, so t...

Problems solved by technology

[0003] Although the above-mentioned patented technical scheme has the advantages described in the 3rd to 6th lines on page 3 of its description, it has the following disadvantages: since the leading screw is located between a pair of guide rails (the patent claims guide rods), it is connected with a pair of guide rails. The length directions of the guide rails are parallel, so the distance between the guide rails is large, which is not conducive to reducing the overall volume of the flat knitting machine, especially the larger the distance between a pair of guide rails, the more difficult it will be for the centering of the shuttle box , affecting the yarn feeding effect
