Description

The structure of anti-circular knitting machine guide channel flocking accumulation

The utility model relates to a kind of anti-knitting machine flocking accumulation structure, is particularly useful for piling up the flocking place near the anti-syringe guide channel.

As everyone knows, circular knitting machine is by the general a large amount of productions that apply to knitting cloth, but, owing to utilize the round needle loom to carry out the knitting man-hour that adds, once must use over one hundred spool to work simultaneously, when especially weaving with cotton yarn, the fibre bits that float and from Yarn supply device and feed carrier, dust fall is very many, and these fiber fines will along with air float and attached to compile fine machine in, on outer each position element, after long-time accumulation, these fiber flockings will seriously hinder the moving element action of machine, cause motion to have some setbacks, even the defective of generation broken yarn or braiding, quality of finished is reduced, especially at precise treatment, the seam loop of high speed is even more serious.

Generally speaking, the braiding portion of circular knitting machine is the most responsive to the influence of fiber flocking, and especially near the accumulation flocking the syringe guide channel is more felt puzzlement; Because a convex guide plate is made in existing braiding portion sinker (flying shuttle sheet Sinker) lower end, offer a corresponding guide channel in the syringe outside, make sinker when braid movement, can not float (sticking up) and rise, keep action accurately, but have following shortcoming:

Guide channel in sinker pushes syringe; when the cotton thread lopping is broken away from; though sinker can not float; but; this guide channel is interior after action after a while; can accumulate many fiber flockings; these flockings can interfere with the convex guide plate of sinker lower end, hinder the regular event of stretching sheet, cause institute to weave cotton cloth and expect the mesh inequality; rough surface; even collude yarn and break and can't proceed braid movement, therefore, must shut down cleaning once after the operation for several days; in cleaning, also to dismantle sinker; element such as bearded needle and tripod; could remove totally, reduce production efficiency.

At present, in order to overcome the often trouble of cleaning of guide channel Integrated Chip, near the improved device of removing flocking of a kind of knitting machine top cylinder convex mouth is proposed, as Fig. 1, shown in 2, mainly be in the syringe guide channel of knitting machine, be drilled with at interval and arrange a plurality of ventilation small sircle holes 15 that run through circlewise, and brush from the guide channel opposite side is jet with an air nozzle, blow the fiber cotton bits that are deposited in the syringe guide channel open, avoid guide channel 17 to pile up the convex guide plate 18 front and back action that flocking hinders sinker 12, yet, this structure also is can prolong some to shut down when clearing up apart from (cleaning in one section 10-14 days once), but can't solve the problem of accumulation flocking in the guide channel 17 fully, mainly be alternately because of the small sircle hole 15 that is bored, and the fiber flocking is different with the fine sand flying dust, their bar shaped fiber can tangle mutually, place, dead angle, interval at circular hole and circular hole can deposit flocking, and the flocking that is deposited can often connect more fiber flocking gradually, can hinder the sinker action, even small sircle hole 15 obstructions of will ventilating, the air-flow that air nozzle is blown out loses effectiveness; In addition; air-flow blows to spraying into flocking from guide channel 17; and bearded needle and sinker 12 that the knitting machine outer rim is all gathered and is provided with; so the gas that in guide channel 17, brushed, therebetween contained fibres of cotton flocks some can be accumulated in bearded needle and the sinker member limits on the guide channel track 16 of its action; therefore; make this two member that running take place through regular meeting and have some setbacks, even produce fault and akinesia.

In view of this, the purpose of this utility model provides the structure of a kind of anti-circular knitting machine guide channel bits accumulation, does not brush the flocking dead angle, and the guide plate of sinker also has the cleaning of striking off and deposits the flocking structure, and in addition, cleaning eye can be for the artificial accumulation flocking of removing in the guide channel.

The purpose of this utility model is achieved in that the structure of anti-round needle loom guide channel flocking accumulation comprises the guide plate of sinker, the guide channel and the pressure-air nozzle of syringe, arc, its upper and lower ora terminalis that the guide plate front end of sinker is indent have the sharp-pointed sword of scraping, and guide plate two sides are the cambered surface of indent, its upper and lower ora terminalis be sharp scrape scrape sword; In the guide channel of syringe, offer a plurality of pass through window thread a needle the ellipse cleaning aperture of a perisporium and the tangent arrangements in big nose end both sides in each aperture; The jet aperture of pressure-air nozzle is over against guide plate one side of sinker.

Owing to adopt such scheme: the flocking accumulation is few, and it is also easy to remove, and need not shut down cleaning, enhances productivity.

Present embodiment mainly is to offer a plurality of cleaning apertures 11 that are the prolate shape through hole that are periphery at circumference at its guide channel 10 of syringe 1 upper edge of circular knitting machine, as Fig. 3, shown in 4, it is big in this cleaning aperture 11 is, outer little taper hole, and the big nose end of each hole is arranged in the tangent state in both sides, as Fig. 8, shown in 9, the front end of sinker guide plate 2 has the indent arc, make, lower extreme point becomes the more sharp-pointed point 21 of scraping, as shown in Figure 5, and dual side-edge also has the indent arc, make, lower rim form sharp scrape scrape sword 22, as shown in Figure 6, one pressure-air nozzle 3 is arranged on a side of sinker, and make the guide plate 2 of its jet aperture 31, pressure-air can be blown in the syringe guide channel 10 over against sinker.

When sinker stretches into the guide channel 10 of syringe with its guide plate 2 in, doing forward and backward motion, pressure-air nozzle 3, be blown into high pressure draught from sinker guide plate 2 sides, making wafts is attached to the high pressure draught that the fiber flocking on sinker guide plate 2 or the syringe guide channel 10 brushed at once and takes away, and is rejected to the external world by cleaning aperture 11; In this process, because cleaning aperture 11 is cut state at syringe guide channel 10 by both sides, forming does not have cleaning dead angle structure, brushes down at high pressure draught, and flocking noresidue dead angle almost on sinker guide plate 2 or syringe guide channel 10 reaches the effect of cleaning flocking; Shown in Fig. 7,8; Pressure-air nozzle 3 is arranged on a side of sinker guide plate 2 again, make the air-flow that contains fibres of cotton flocks, discharge in the self-cleaning aperture, do not accumulate part and there is flocking, moreover remaining small part flocking heap for a long time can move back and forth by sinker guide plate 2 in the guide channel 10, scrape point 21 and side with its front end and scrape sword 22 and produce and remove flocking, get rid of through high pressure draught again.

Than outside, when adopting the still residual flocking of said structure, have to shut down, scrape with front end band commonly used and collude thin rod (not shown), self-cleaning aperture 11 is stretched in the guide channel 10, with the flocking soil release, and need not dismantle any member.
