Abstract

The utility model belongs to a hand-operated yarn collection mechanism of the flat knitting machine and relates to the technical field of the knitting machinery, in particular to a hand-operated yarn collection mechanism of the flat knitting machine, realizing through the following technical project, a plurality of through grooves arranged abreast are arranged on the main support in the shape of the door. One side of the main support in the shape of the door is provided with a hole corresponding to every through groove, and one end of the slide bar with the hole for passing the yarn is inserted into the hole, sheathing with a spring. A directional screw passes through the through groove on the main support, fixed on the slide bar. A locking plate is arranged on the upper side of the main support. The front end of the locking plate is provided with barbs corresponding to the through grooves on the main support, and the number of the barbs is same as the number of the corresponding through grooves. The screw passes through the elongated groove on the locking plate and makes the locking plate be movably locked on the main support. One end of the pullback spring is fixed on the main support, the other end is fixed on the locking plate, and the main support is fixed on the machine frame through the support. A yarn nozzle with the automatic thread-changing is fixed on the head section. The utility model is reasonable structure, easy operation, greatly decreasing the time of the yarn-changing, simplifying the structure and reducing the friction and the probability of the yarn cutting of the yarn.

Description

The moving yarn mechanism that selects of horizontal volume tractor driver

Technical field:

The utility model relates to technical field of knitting machinery, and that refers in particular to a kind of horizontal volume machine manually selects yarn mechanism.

Background technology:

Along with the technology of Knitting Machinery constantly develops, the mechanical, electrical brain machine of some automatic, semi-automatic horizontal volumes is constantly released in succession.But no matter if the horizontal volume machine of any form because by the versicolor reason of fabric, need carry out thread-changing (colour changing) and all rely on replacing yarn mouth to realize.Because of versicolor line all is to pass different yarn mouths.Manual colour changing is that the yarn mouth that will store up by hand on the yarn socket is changed on the yarn seat of head drive; On guide rail, wait for replacement and those automatic, automanual colour changings must be 6～8 yarn mouths, select needed yarn mouth by control system again, then, under the drive of head, on guide rail, slide and change.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of horizontal volume tractor driver is provided the moving yarn mechanism that selects.

The utility model is achieved by the following technical solution: the master who is a shape supports and offers some grooves that are arranged side by side, one side of the main supporting of door shape, corresponding each groove, be provided with a hole, slide bar one end that has the hole of entrying is plugged in the hole, and being with spring, directional bolt passes the groove in the main supporting, is installed on the slide bar; Locking plate places above the main supporting, groove in the corresponding main supporting of the front end of locking plate is provided with the barb of respective number, screw is tied the movable lock of locking plate in main supporting by the elongate slots on the locking plate, extension spring one end is fixed in the main supporting, the other end is fixed on the locking plate, will lead supporting by supporting and be fixed on the frame; Be fixed with V-shaped and yarn on the head and chew automatic thread-changing yarn mouth towards a left side.

The utility model is rational in infrastructure, and is easy and simple to handle, reduced greatly and changed the needed time of yarn, both simplifies the structure, and also reduced friction, also reduced the broken string probability of yarn.

The specific embodiment:

See accompanying drawing 1～4, the utility model comprises:: the main supporting on 1 that is a shape offers some grooves that are arranged side by side 11, one side of the main supporting 1 of door shape, corresponding each groove 11, be provided with a hole 12, slide bar 9 one ends that have the hole 91 of entrying are plugged in the hole 12, and are with spring 10, directional bolt 8 passes the groove 11 in the main supporting 1, is installed on the slide bar 9; Locking plate 3 places above the main supporting 1, groove 11 in the corresponding main supporting 1 of the front end of locking plate 3 is provided with the barb 31 of respective number, screw 6 is tied locking plate 3 movable locks in main supporting 1 by the elongate slots 32 on the locking plate 3, extension spring 5 one ends are fixed in the main supporting 1, the other end is fixed on the locking plate 3, will lead supporting and 1 be fixed on the frame by supporting 2; Be fixed with V-shaped on the head and yarn is chewed the 41 automatic thread-changing yarn mouths 4 towards a left side.

See accompanying drawing 1～6, when using the utility model, if do not advance slide bar 9 to move inwards, 9 of slide bars are under the effect of spring 10, an end that has the hole 91 of entrying outwards protrudes out, entry yarn 7 outward-dipping angles in the hole 91 move right through yarn 7 on guide rail and when returning if head drives automatic thread-changing yarn mouth 4, and yarn 7 is outward-dipping to make yarn on the automatic thread-changing yarn mouth 4 chew 41 can not to capture these yarns 7; If when need selecting any one thread 7, advance inwards with pointing the slide bar 9 that has the yarn 7 of the sort of color in the hole 91 of to entry, directional bolt 8 companions that are installed on the slide bar 9 are moved, and push barb 31 on the locking plate 3 open, snap in the barb 31, locking plate 3 resets under the effect of extension spring 5, at this moment, yarn 7 is in plumbness, and head drives automatic thread-changing yarn mouth 4 and moves right on guide rail through yarn 7 and when returning, and the yarn 7 of plumbness makes the yarn on the automatic thread-changing yarn mouth 4 chew 41 and captures these yarns 7 easily and weave, that root slide bar 9 that need change yarn 7 then can eject under the effect of spring 10 automatically, and yarn 7 automatically breaks away from yarn and chews 41.
