Abstract

The utility model belongs to an automatic yarn selecting mechanism of the flat knitting machine and relates to the technical field of the knitting machine, in particular to an automatic yarn selecting mechanism of the flat knitting machine, realizing through the following technical project: a main support is fixed on the machine frame. Electromagnets with the staggered position in two rows are fixed on the main support. An upper lever shaft and a lower lever shaft are mounted on the axle seats on both sides of the main support. The middle part of the lever hinged with the upper lever shaft is U-shaped, and an elongated grooved pin shaft arranged on the lever is connected with the electromagnet core in the upper row. A lever pin shaft hinged with the lower lever shaft is connected with the electromagnet core in the lower row. Two rows of the levers are crisscross mounted. The position with the U-shaped in the middle part of the lever is corresponding to the position of the lower lever shaft. The upper end of the lever is connected with the pullback spring fixed on the main support. The lower end of the lever is movably connected with a slip line ear. The slip line ear is arranged in the chute of the slide seat, and the hole for passing the yarn is arranged on the slip line ear. A yarn nozzle with the automatic thread-changing is fixed on the head section. The utility model has the advantages of reasonable structure, easy operation, greatly decreasing the time of the yarn-changing, omitting the superfluous rail, simplifying the structure and reducing the friction and the probability of the yarn cutting of the yarn.

Description

Horizontal volume machine selects yarn mechanism automatically

Technical field:

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

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 be to provide a kind of rational in infrastructure, easy and simple to handle, both saved unnecessary guide rail, the horizontal volume machine that simplifies the structure again selects yarn mechanism automatically.

The utility model is achieved by the following technical solution: main supporting is fixed on the frame, being the staggered electromagnet of two rows and position is fixed in the main supporting, on, following two lever shafts are installed on the axle bed of main supporting both sides, its middle part of lever that is hinged on the upper lever axle is the U type, elongate slots bearing pin on it is connected on row's the electromagnet core, the lever bearing pin that is hinged on down on the lever shaft is connected down on row's the electromagnet core, the staggered installation of two row's levers, and the position that its middle part of lever is the U type is suitable with following lever shaft position, the upper end of lever is connected with extension spring on being fixed on main supporting, the lower end of lever is connected with the line of slide ear, the line of slide ear is inserted in the chute of slide, and offers through wires hole on the line of slide ear; 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 saved unnecessary guide rail, simplifies the structure again, also reduced friction, also reduced the broken string probability of yarn.

The specific embodiment:

See accompanying drawing 1～4, the utility model comprises: main supporting 2 is fixed on the frame, being the staggered electromagnet 6 of two rows and position is fixed in the main supporting 2, on, following two lever shafts 4 are installed on the axle bed 3 of main supporting 2 both sides, lever 5 its middle parts that are hinged on the upper lever axle 4 are the U type, elongate slots 51 bearing pins on it are connected on row's the electromagnet core 61, lever 8 bearing pins that are hinged on down on the lever shaft 4 are connected down on row's the electromagnet core 61, two row's levers 5,8 staggered installations, and the position that lever 5 its middle parts are the U type is suitable with following lever shaft position, lever 5,8 upper end is connected with extension spring 9 on being fixed on main supporting 2, lever 5,8 lower end is connected with line of slide ear 12, line of slide ear 12 is inserted in the chute of slide 11, and offers the hole 121 of entrying on the line of slide ear 12; Be fixed with V-shaped on the head and yarn is chewed the 11 automatic thread-changing yarn mouths 1 towards a left side.

See accompanying drawing 1～6, when using the utility model, if electromagnet 6 is not charged, under the effect of extension spring 9, lever 5,8 rotates around upper and lower two lever shafts 4 respectively, and outwards swing the lower end of lever 5,8, like this, lever 5,8 just will offer 12 groups in the line of slide ear in the hole 121 of entrying to the outer end of the chute of slide 11, and also angle of deflection thereupon of the yarn 7 in the hole 121 of entrying; At this moment, move right on guide rail through yarn and when returning if head drives automatic thread-changing yarn mouth 1, yarn is outward-dipping to make yarn on the automatic thread-changing yarn mouth 1 chew 11 can not to capture these yarns; When needs are changed the yarn of certain color, corresponding electromagnet core 61 is under the effect of control system, the energising adhesive, electromagnet core 61 moves inwards, driving corresponding lever 5 or 8 moves inwards, with the yarn band to the inside, yarn is in plumbness, head drives automatic thread-changing yarn mouth 1 and moves right on guide rail through yarn and when returning, the yarn of plumbness make the yarn on the automatic thread-changing yarn mouth 1 chew 11 easily the pond capture these yarns and weave, the yarn of changing then can automatically break away from yarn and chew 11.Suitable with following lever shaft position because of the position that lever 5 its middle parts are the U type, when it took place around 4 swings of upper lever axle, the moulding of U type can not interfere phenomenon with upper lever axle 4.If adopt the structure of the electromagnet 6 of single row, then can be, but the increase of the length of main supporting 2 only with a lever shaft 4, the stroke of head is reduced, and can implement the technical program equally, also at the row of this patent protection.
