Description

A kind of yarn paper tube

Technical field

The utility model relates to a kind of yarn paper tube.

Background technology

Present employed yarn paper tube; Be to roll into the paper tube shape mostly with the paper that multilayer cuts into the slanted bar shape; But this paper tube that rolls into can form burr and sharp-pointed corner in the end at two, in the process of winding yarn, cuts off yarn and causes spinning work to pause through regular meeting.

In order to address the above problem; The structure of another kind of yarn paper tube (or claiming U type yarn paper tube) 90; As shown in Figure 1, through with the end limit of yarn paper tube 90 91 toward the inner bending closings in the inside of yarn paper tube 90, the outer end of yarn paper tube 90 is modified to circular-arc U type head 92.

Yet the U type head 92 of this yarn paper tube 90 is resistant to pressure not, and is vulnerable to weight and deforms.This yarn paper tube 90 is placed on the arbor 95 of spinning machine and during along with rotating shaft 95 high speed revolutions; This yarn paper tube 90 process bending processes ability closings are in 90 in-to-in end limits, the 91 meeting perks a little of yarn paper tube; Except meeting cause said yarn paper tube 90 block rotating shaft 95 and can't the axis of rotation 95 on the situation of taking out, to such an extent as to more can cause the U type head 92 of this yarn paper tube 90 to collude the yarn that breaks and twining because distortion is broken.And, the U type head of this yarn paper tube 90 92 in case distortion just must abandon, can not repeated usage, so the service life of this yarn paper tube 90 is shorter, influence economic benefit.

The utility model content

In view of this, the technical matters that the utility model will solve can reusable yarn paper tube for providing a kind of ability under pressure, indeformable.

For solving the problems of the technologies described above; The utility model provides a kind of yarn paper tube; Cut the material tube wall with what the tube wall front end of yarn paper tube cut into integral structure; Constitute jointly by a cephalic par, one first cut surface and one second cut surface, thus can be so that the end of yarn paper tube possesses tolerance weight and indeformable characteristics; The said cephalic par of cutting the material tube wall; Be formed in said outer end of cutting the material tube wall; And thickness is between 2-15mm; Be made up of jointly an interior round nose angle, a tack end face and a cylindrical naricorn, round nose angle is to constitute circular arc chamfering with first radius R 1 in this, and this butt end mask is equipped with plane width L1 and this cylindrical naricorn is to constitute circular arc chamferings with second radius R 2; Said first cut surface of cutting the material tube wall is to begin to be first inclined angle alpha and this second cut surface crossing from the crossing face with the interior round nose angle of this cephalic par; Said second cut surface of cutting the material tube wall begin to constitute a cut surface to be second angle of inclination beta from the crossing face with this first cut surface, and the angle between first cut surface and second cut surface is the obtuse angle.

The yarn paper tube of the utility model has following beneficial effect through the tube wall end construction is improved:

1, the tube wall front end of yarn paper tube be integral structure cut the material tube wall, possess tolerance weight and indeformable characteristics;

When 2, the yarn paper tube was placed on the rotating shaft high speed revolution of spinning machine, the end of yarn paper tube was difficult for deforming or breaking, and more can not cause the clamping stagnation rotating shaft or collude the broken yarn line; And

3, the yarn paper tube can reclaim repeated usage and increase service life.

Reference numeral

Like Fig. 2 and shown in Figure 3; The yarn paper tube 10 of the utility model; Be to be wound into a hollow circuit cylinder body 11 with the multilayer synthetic paper; And tube wall 12 structures of this hollow circuit cylinder body 11 are with cutting the front end of tube wall 12 to be formed one to cut material tube wall 13, and its structure comprises a cephalic par 14, one first cut surface 15 and one second cut surface 16.

Said cephalic par 14 is formed in this outer end of cutting material tube wall 13; And its thickness is made up of an interior round nose angle 14a, a tack end face 14b and a cylindrical naricorn 14c, wherein between 2-15mm; Should constitute circular arc chamfering with first radius R 1 by interior round nose angle 14a; This tack end face 14b is the end face that possesses plane width L1, and this cylindrical naricorn 14c constitutes circular arc chamferings with second radius R 2, and meets the following conditions:

1mm≦R1≦7.5mm；

0mm≦L1≦13mm；
