Abstract

The utility model discloses the automatic threading yarn pipe of a kind of elasticity, aperture within one week, is offered uniformly as ring-type repiece region along barrel body, be provided with annular shell fragment in described barrel body inside with corresponding position, ring-type repiece region, the elastic surface of described annular shell fragment is being provided with and aperture burr one to one in bobbin surface direction; The utility model 360 °, ring-type repiece region scope offered some apertures in one week at barrel body, inner correspondence arranges shell fragment, and burr during shell fragment pressurized on it stretches out aperture, thus makes that yarn is sticky to be paid on burr, replace traditional repiece suede band, make automatic doffing repiece rate reach 100%; When annular shell fragment is not stressed, burr, then in retraction bobbin housing, makes bobbin surface smooth once again, realizes yarn noresidue, without the need to manual operation.

Description

The automatic threading yarn pipe of a kind of elasticity

Technical field

The utility model relates to field of textile machinery, is specifically related to a kind of fly frame.

Background technology

The flyer bobbin that in prior art, automatic doffing roving frame uses, its repiece principle is nearly all adopt to wrap up one deck suede band on flyer bobbin top or bottom, when starting to spin, allowing yarn glue and being posted on suede band, reaching the object of repiece.The repiece rate of rove, about 80%, also needs to be aided with artificial repiece, increases the work capacity of rove spinner.The reason that repiece rate is not high is embodied in the following aspects:

First, the flyer bobbin of current use, when repiece by the impact of flyer presser yarn outlet position, starting to spin, pressing device yarn outlet does not press close to bobbin suede band, yarn can not contact with suede band, head can be gathered around at fly frame scroll tube with upper part, cause rove repiece rate not high, be not well positioned to meet the requirement of the automatic repiece of rove;

Secondly, in use for some time, suede band can adhere to one deck fiber, even produce a large amount of electrostatic, the adhesive force of suede band can weaken the flyer bobbin used at present, and when causing repiece, yarn can not be attached on spool, affects automatic repiece rate;

Finally, the flyer bobbin used at present is suede band adhesion type, can be difficult to cleaning after rove attachment, causes tail yarn and removes unclean problem, needs to drop into labor cleaning and the situation creating rove waste.

From above-mentioned, current existing spool structure has not been well positioned to meet the requirement of the automatic repiece of automatic doffing roving frame, awaits improving further and developing.

Utility model content

Utility model object: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of and realizes automatic repiece, adheres to the good automatic threading yarn pipe of elasticity of yarn effect.

Technical scheme: the automatic threading yarn pipe of a kind of elasticity, aperture within one week, is offered uniformly as ring-type repiece region along barrel body, be provided with annular shell fragment in described barrel body inside with corresponding position, ring-type repiece region, the elastic surface of described annular shell fragment is being provided with and aperture burr one to one in bobbin surface direction.Annular shell fragment can make burr be passed by the aperture in ring-type repiece region when being stressed, thus makes yarn stick on burr; When annular shell fragment is not stressed, in burr automatic retraction bobbin housing, make bobbin surface smooth once again, realize yarn noresidue.

Further, the fixed form of annular shell fragment is that the upper and lower two ends of elastic surface of described annular shell fragment are fixed on the inwall of described barrel body, middle part is inwardly shunk and is formed concave surface, space between concave surface and barrel body inwall is for holding burr, when annular shell fragment is not stressed, burr is placed in barrel inner, can not embody in bobbin outside, ensure that bobbin outer wall is smooth.

Beneficial effect: the utility model 360 °, ring-type repiece region scope offered some apertures in one week at barrel body, inner correspondence arranges shell fragment, burr during shell fragment pressurized on it stretches out aperture, thus make sticky pair of yarn on burr, replace traditional repiece suede band, make automatic doffing repiece rate reach 100%; When annular shell fragment is not stressed, burr, then in retraction bobbin housing, makes bobbin surface smooth once again, realizes yarn noresidue, without the need to manual operation.

Detailed description of the invention

Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.

embodiment: the automatic threading yarn pipe of a kind of elasticity, as shown in Figure 1, is provided with the ring-type repiece region 2 it evenly being offered aperture 3 for 1 one weeks, the tube wall of the through barrel body 1 of aperture 3 along barrel body.As shown in Figure 2, be provided with annular shell fragment 4 in barrel body 1 inside with corresponding position, position, ring-type repiece region 2, the upper and lower two ends of elastic surface of annular shell fragment 4 are fixed on the inwall of barrel body 1, and formation concave surface is inwardly shunk at middle part.In the direction of concave surface facing barrel body 1 inwall, annular shell fragment 4 is provided with and aperture 3 burr 5 one to one.

Barrel body 1 is when fly frame starts to spin, annular shell fragment 4 is subject to spindle blade extruding, burr 5 reaches outside annular repiece region 2 through aperture 3, yarn adheres to when repiece on burr 5, thus achieve the winding of yarn on barrel body 1, reach the object of the automatic repiece of rove, make automatic doffing repiece rate reach 100%.After full yarn doffs, when barrel body 1 takes off from spindle blade, annular shell fragment 4 is not stressed and just restores to the original state, and it is inner that burr 5 is retracted to barrel body 1, achieves yarn and automatically disengage bobbin outer wall, improve rove degree of utilization, decrease the labor content of workman.

Claims

1. the automatic threading yarn pipe of elasticity, it is characterized in that: within one week, offer aperture uniformly as ring-type repiece region along barrel body, be provided with annular shell fragment in described barrel body inside with corresponding position, ring-type repiece region, the elastic surface of described annular shell fragment is being provided with and aperture burr one to one in bobbin surface direction.

2. the automatic threading yarn pipe of elasticity according to claim 1, is characterized in that: the two ends up and down of described annular shell fragment are fixed on the inwall of described barrel body, and formation concave surface is inwardly shunk at middle part.
