Description

The structure of knitting machine yarn feeder

Technical field

The utility model relates to mechanical, and particularly a kind of structure of knitting machine yarn feeder refers to a kind of structure that can control the yarn storage capacity of yarn storage wheel and effectively control the knitting machine yarn feeder of its operating condition especially.

Background technology

Growing along with textile industry, special weaving facility all need thread feeding apparatus irregular, intermittent yarn consumption, to adapt to various yarn feeding demand, because general yarn-feeding device can't sense institute's expense of yarn, cause situations such as regular generation yarn accumulation, winding, and then cause defectives such as tension change, the cloth surface of yarn itself is impaired.

The shortcoming of above-mentioned existence, there has been relevant dealer to improve, for example adopt the mode of optical sensor, though the storage consumption of its energy sensing yarn, but this induction mode is as the detecting media with light, therefore when light is obstructed, then can't reach the situation of detecting yarn storage consumption, situations such as yarn accumulation, winding in the past still can take place.

The utility model content

The purpose of this utility model is to provide a kind of structure of knitting machine yarn feeder, solve situations such as regular in the past generation yarn accumulation, winding, and problem such as tension change, the cloth surface of causing yarn itself is impaired, and the mode of employing optical sensor is as the detecting media, when light is obstructed, then can't reach the situation that the detecting yarn stores consumption, the problem of situation in the past still can take place.

A kind of structure of knitting machine yarn feeder, this yarn feeder is provided with the yarn feeding wheel that is driven a yarn storage wheel by a power transmission shaft, reach an arithmetic logic unit for control clutch device, wherein, this yarn feeder is adjacent to the yarn storage wheel end and is provided with a magnetic force induction device that is connected with this arithmetic logic unit, and this yarn storage wheel in an end be provided with one with the corresponding magnetic force control of this magnetic force induction device, deviate from this magnetic force control one end yarn amount control piece that then locks, this yarn amount control piece is provided with an elastic parts that is connected with this magnetic force control, like this, can control what of storage yarn amount through the interlock of this yarn amount control piece and this elastic parts, and use the magnetic force induction mode to control the motion of this arrangement of clutch again, and then control the rotary state of this yarn storage wheel, replenish with yarn at yarn storage wheel.

Wherein more comprise the brake gear of being located in this yarn feeder and being subjected to this arithmetic logic unit control;

Wherein the set magnetic force control of this yarn storage wheel is subjected to the interlock of this yarn amount control piece and this elastic parts to be a heeling condition;

Wherein this yarn amount control piece is a bolt;

Wherein this elastic parts is a spring.

Advantage of the present utility model is: the magnetic line of force can not be subjected to the influence of veil and the bad situation of signal takes place.

The specific embodiment

Shown in accompanying drawing 1 and accompanying drawing 2, schematic perspective view and generalized section for the utility model preferred embodiment, find out that by knowing among the figure the utility model comprises: yarn feeder 1 is provided with a yarn feeding wheel 4 by power transmission shaft 2 drive yarn storage wheels 3, reach an arithmetic logic unit 12 for control clutch device 10 and brake gear 11, wherein, this yarn feeder 1 is adjacent to these yarn storage wheel 3 ends and is provided with a magnetic force induction device 14 that is connected with arithmetic logic unit 12, and yarn storage wheel 3 in an end then be provided with one with magnetic force induction device 14 corresponding magnetic force controls 30, deviating from magnetic force control 30 1 ends then locks a yarn amount control piece 32 is arranged, this yarn amount control piece 32 is provided with an elastic parts 34 that is connected with magnetic force control 30, by this, what of storage yarn amount the interlock of warp thread amount control piece 32 and elastic parts 34 can control, and the running of using magnetic force induction mode control clutch device 10 or brake gear again by the signal computing of arithmetic logic unit 12, and then the rotary state of control yarn storage wheel 3.

By above-mentioned structure, form design, be described as follows with regard to use situation of the present utility model, as shown in Figures 3 to 5, section mode of operation schematic diagram for the utility model control yarn storage wheel storage capacity, the operating state schematic diagram of the full yarn of the yarn of yarn storage wheel and the yarn of yarn storage wheel lack the operating state schematic diagram of yarn, find out by knowing among the figure, yarn storage wheel 3 is equiped with yarn amount control piece 32 in an end, yarn storage wheel 3 other ends then are provided with magnetic force control 30, on yarn amount control piece 32, connect an elastic parts 34, this elastic parts 34 is attached to magnetic force control 30 to produce the interlock state, when user's desire is adjusted the storage yarn amount of yarn storage wheel 3, can be by yarn amount control piece 32 with elastic parts 34 tensions, because this moment, magnetic force control 30 elastic parts 34 elasticity numbers were higher, so it is more that yarn can store,, then yarn amount control piece 32 can be transferred pine if when needing less storage yarn amount, reduce the elasticity number of elastic parts 34, also can make the easy parallel induction in angle of inclination of magnetic force control 30.

After being adjusted to the appropriate tilt angle, magnetic force control 30 begins to store up yarn, because the relation that magnetic force control 30 tilts makes magnetic force control 30 and magnetic force induction device 14 can't produce the magnetic line of force, thereby arithmetic logic unit 12 starts arrangement of clutch 10 immediately, yarn feeding wheel 4 meetings this moment are turned round and are driven yarn storage wheels by arrangement of clutch 10 through power transmission shaft 2 and rotate, thereby allow yarn constantly continue to be wound in yarn storage wheel 3.

After yarn constantly increases, magnetic force control 30 was subjected to the weight increase of yarn and dwindled the angle of inclination gradually this moment, when magnetic force control 30 is line one level, then can produce magnetic field mutually with the magnetic force induction device 14 on the yarn feeder 1, yarn feeder 1 interior arithmetic logic unit 12 received the magnetic force signal and made arrangement of clutch 10 break away from power transmission shafts 2 this moment, after arrangement of clutch 10 breaks away from power transmission shaft 2, because of the inertia action presents idling conditions, brake gear 11 can slow down synchronously to power transmission shaft 2 and yarn storage wheel 3 simultaneously, and stops to mend yarn.

Otherwise, when the yarn on the yarn storage wheel 3 successively decreases gradually, magnetic force control 30 tilts gradually, when healing when big in the angle of inclination, then can interrupt and magnetic force induction device 14 between magnetic field, and arithmetic logic unit 12 can't be received the magnetic force signal, because arrangement of clutch 10 belongs to the state of continuous running, therefore when arithmetic logic unit 12 control clutch device 10 combine with power transmission shaft 2, its power can drive yarn storage wheels 3 synchronously and mend yarn by power transmission shaft 2, by said structure, can control what of storage yarn amount effectively, in addition, the magnetic line of force can not be subjected to the influence of veil and the bad situation of signal takes place.
