Abstract

The utility model discloses a tail yarn winding and locating device for a covering machine. The device comprises a yarn guide rod, an annular sleeve, a gasket, a fastening screw and a yarn guide hook made by a stainless steel wire. The annular sleeve is fixed on the yarn guide rod through the fastening screw, and the gasket and the yarn guide hook are both located between the annular sleeve and the fastening screw. A yarn input and output channel is arranged on the yarn guide hook. The tail yarn winding and locating device for the covering machine reduces friction to yarns, the quality of tail yarns is improved, and waste of a yarn material is reduced.

Description

Tail yarn coil positioning device for coating machine

Technical field

The utility model relates to a kind of registration device, particularly relates to tail yarn coil positioning device for a kind of coating machine.

Background technology

In the production process of hollow ingot wrap yarn, the yarn that completes looping twisting is exported under the guiding of drawing the yarn roller, walks around guide bar, and the thread eye through traversing with the guide bar that traverses, be wound up on spool, and spool is by the take up roll frictional transmission.The traverse that the guide bar that traverses back and forth traverses, determined the coiling traverse scope of yarn on spool.Needs for later process processing, at yarn, starting to reel is that blank pipe is while reeling, need to stay the tail yarn, when blank pipe starts to reel a few loop yarn line of beginning, be wound on outside the normal winding scope of spool, this part yarn is called as " tail yarn ", the purpose of doing like this is that the loose thread when starting to reel is stayed outside the normal winding layer, avoiding being wound layer hides, its effect is in following process, can find easily the yarn tail of bobbin yarn, and it and the loose thread of another cheese are connected together, when a bobbin unwinding is finished, because yarn tail and another are taken over the cheese loose thread and are joined, taking over the bobbin yarn starts unwinding and continues to export incessantly yarn, realized creeling and do not affected the continuous wave output of yarn.

Because being wound on outside the normal winding scope of tail yarn, therefore can not by the guiding of thread eye, realize reeling, but, by the coiling that is arranged on a special device on guide bar and locates the winding position of tail yarn and guide the tail yarn, this special device is tail yarn registration device.This device is sleeved on guide bar, after determining tail yarn winding position, can its position be fixed on guide bar by holding screw.When starting blank pipe coiling tail yarn, yarn is placed in to the yarn groove of this device, reel in bootable yarn coiling tail yarn position on spool, reel after a fixing turn, yarn is taken out from the yarn groove, be placed in the thread eye traversed with the guide bar that traverses in the normal winding scope, start normal winding.Like this, the yarn tail has just been stayed outside the normal winding scope, and can not hidden by the yarn of normal winding.

What existing hollow ingot coated the employing of tail yarn registration device is the yarn slot type, and for the needs of install and adjust installation site on guide bar, its material adopts rigid plastic, is shaped as ring-type, and has yarn guiding trough, when coiling tail yarn, as the passage of guide.

By application aborning, although find that this device can realize tail yarn guide function, there is following shortcoming:

One, yarn groove guide, yarn and yarn groove friction length are long, cause friction force larger;

Two, plastic material yarn guiding trough, due to material character and working accuracy reason, surface is bright and clean not, large to thread friction power.

Three, because the yarn groove is large to thread friction power, the scared phenomenon of tail yarn is serious, and Quality Down adds and the yarn of coiling tail yarn part need to be removed to joint again in later process man-hour, has caused the waste of yarn.

The utility model content

Technical problem to be solved in the utility model is to provide tail yarn coil positioning device for a kind of coating machine, and it reduces its friction to yarn, improves the tail yarn quality, reduces the waste of thread material.

The utility model solves above-mentioned technical matters by following technical proposals: tail yarn coil positioning device for a kind of coating machine, it comprises the guide wire that guide bar, ring-shaped sleeve, packing ring, holding screw and STAINLESS STEEL WIRE are made, described ring-shaped sleeve is fixed on guide bar by holding screw, and described packing ring, guide wire are all between ring-shaped sleeve and holding screw.

Preferably, described guide wire is provided with a yarn access way.

Positive progressive effect of the present utility model is: the utility model reduces its friction to yarn, improves the tail yarn quality, reduces the waste of thread material, has avoided that thread friction is scared, the generation of Quality Down phenomenon.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As shown in Figure 1 to Figure 3, the utility model coating machine comprises with tail yarn coil positioning device the guide wire 5 that guide bar 1, ring-shaped sleeve 2, packing ring 3, holding screw 4 and STAINLESS STEEL WIRE are made, ring-shaped sleeve 2 is fixed on guide bar 1 by holding screw 4, and packing ring 3, guide wire 5 are all between ring-shaped sleeve 2 and holding screw 4.Guide wire 5 is provided with a yarn access way 7.

Yarn can be by the turnover of yarn access way, and during normal guide, yarn is positioned at the annulus top.When the tail yarn is reeled, yarn is introduced to guide wire by the yarn access way, only contact with the guide wire top during yarn movement, because area of contact is very little, friction force is less, has solved the scared problem of the excessive yarn of friction.After the tail yarn has been reeled, yarn is taken out via the yarn access way, put into the thread eye traversed with the guide bar that traverses, start normal winding.Guide wire adopts the STAINLESS STEEL WIRE bending process to form, because STAINLESS STEEL WIRE hardness is large, and smooth surface, and little with the yarn area of contact, the friction force to yarn when guide reduces greatly, thus the scared phenomenon of thread friction while substantially having eliminated tail yarn coiling.

The utility model reduces its friction to yarn, improves the tail yarn quality, reduces the waste of thread material, has avoided that thread friction is scared, the generation of Quality Down phenomenon.

Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
