Description

A kind of yarn winding device convenient for fixed the end of a thread

Technical field

The utility model is related to a kind of spinning equipment, more particularly to a kind of yarn winding device convenient for fixed the end of a thread.

Background technology

Before being wound to yarn, the end of a thread by yarn one end is needed to be fixed on wind-up roll, it could be to subsequent yarn Line is smoothly wound, and existing wind-up roll uses a roll body, and manually one end of the end of a thread is wound up on roll body, is then passed through Two loop yarn lines compress the end of a thread, but since roll body surface is smooth, cloth one end is wound up on roll body by inconvenience, to also be unfavorable for The winding work of follow-up cloth.

Yarn is in coiling process, if uneven by retracting power, it is easy to which there is a situation where broken yarn, yarn coiling processes In, since diameter gradually increases, by the realization of being swung left and right of yarn releasing roll around however still there is the mutation of end winding diameter The case where, cause yarn stress to change suddenly, not only influence yarn takes up uniformity, but also there are the danger of broken yarn Danger；After the completion of retracting, the fixation of the end of a thread is also that more stubborn problem, the end of a thread is not easily found, and passes through traditional clampingslot type knot Structure, it is easy to the end of a thread be caused to lose or be difficult to take out.

Utility model content

The purpose of this utility model is the existing above problem in view of the prior art, is provided a kind of convenient for fixed the end of a thread Yarn winding device, technical problem to be solved in the utility model are how two the end of a thread of yarn to be fixed, and make it just In installation and take out.

The purpose of this utility model can be realized by following technical proposal：A kind of yarn winding device convenient for fixed the end of a thread, It is characterized in that, yarn winding device includes a retracting roller, retracting roller includes ontology and shaft, and installation is offered in the middle part of the ontology Hole, the shaft are plugged in mounting hole, and obstruct ontology by one between the inner wall of the hole installing and shaft outer wall revolves around the shaft The damping structure turned is connected, and the both ends of the ontology are respectively provided with end plate, and the outside of the end plate, which has, to be set in shaft Latch, several locating slots are offered on the lateral surface of the end plate, the locating slot includes being between one and shaft axis The inclined surface one of 30~70 ° of angles, have on the latch with the one-to-one inserted block of locating slot, have on the inserted block The inclined surface two being adapted to inclined surface one；It is connected by a torsional spring between the latch and end plate, the torsional spring drives inclination Face one and inclined surface two are pressed.

The end of a thread can be fixed by inserted block and locating slot, be opened up before yarn, pull latch outward, make locking Plate is far from end plate one end distance, under the action of torsional spring, while latch moves outward, still wants to the direction rotation of inclined surface one Turn, forms the installation space of the end of a thread between the inner wall of inserted block and locating slot in addition to inclined surface one, after the end of a thread is installed, pine Open locking plate can be such that the end of a thread is fixed in locating slot by inserted block by the guiding role of inclined surface one and inclined surface two.

Latch is strip, forms stress space between latch and end plate and also allows for entirely furling convenient for putting forth effort The carrying and placement of roller.

In a kind of above-mentioned yarn winding device convenient for fixed the end of a thread, there are two the locating slots, and is evenly distributed on end On plate.

In a kind of above-mentioned yarn winding device convenient for fixed the end of a thread, the damping structure includes that several axial directions are distributed in Damper assembly between shaft and ontology, the damper assembly include the mounting groove that several are uniformly opened in shaft circumference One, offer on the inner wall of the mounting hole with one one-to-one mounting groove two of mounting groove, be embedded in the mounting groove one Permanent magnets are embedded with iron block in the mounting groove two, and the shaft is made of aluminum alloy material.

Multiple damper assemblies can make to be positioned between shaft and ontology, and dismounting is extremely convenient, directly by shaft It is inserted into suitable position, and after being inserted into, is positioned, had reliable between the equal countershaft of each damper assembly and ontology Spend high advantage.

At the same time, ontology needs to overcome the adsorption capacity between permanent magnets and iron block relative to shaft rotation, larger in appearance When tension variation, overcomes adsorption capacity that ontology can be made to be rotated relative to shaft, yarn is protected, in the case of normal work, The structure also has the function of buffering and adjust to the variation of yarn tension.

In a kind of above-mentioned yarn winding device convenient for fixed the end of a thread, the lateral surface and shaft outside wall surface of the permanent magnets it Between distance be more than the distance between inner wall of the hole installing and shaft outside wall surface.

Permanent magnets are arranged in shaft, it is convenient that it is cleared up and is safeguarded, in the process that ontology is rotated relative to shaft In, relative friction does not occur between permanent magnets and iron block, keeps operating reliable, permanent magnets is avoided to wear, and permanent magnets and iron block The structure of indent can be also used for storage lubricating oil, iron filings etc., avoid running between shaft and ontology unsmooth.
