Abstract

The utility model relates to a paper tube winding spindle, which comprises a spindle casing, a spindle blade, rolling bearing arranged on a spindle blade end, a sealing cover, a bearing cover, elastic washers, and fixing screws fixed to form a body. The utility model is characterized in that the spindle casing comprises a front spindle casing and a back spindle casing relatively embedded, and a buckled pipe ring is made from polyurethane rubber. A middle support block is formed on the outer circumference of the embedded end of one of the front spindle casing and the back spindle casing for making a yarn cop bear the yarn tension and obtaining the qualified bobbin yarn. The utility model has the advantages of convenient loading and unloading and long service life.

Description

Can bear the paper tube type Winding spindle of high yarn tension

The utility model relates to a kind of doff spindle, relates to a kind of circular cone paper tube type spindle with the rolling bearing supporting specifically.

The applicant has disclosed a kind of circular cone paper tube type spindle with the rolling bearing supporting in state's utility model patent 90207037.1 therein, solve the axially movable problem between lubrication problem and spindle blade and spindle shell effectively, but also there is following problems: because spindle only cooperates with small end two places at big end with paper tube, the intermediate portion does not contact, and this mid portion length is bigger, therefore when after being wound with the yarn of high-tension on the paper twine pipe, the mid portion of paper twine pipe will shrink distortion, thereby but, mid portion do not cause the paper twine bore to shrink to diminish to bite the spindle small end because of having to support, pull out to get off after a yarn is finished, the result be to prescind whole networks around yarn after just can take off spool; Because original set button pipeloop is to make with the ordinary rubber material, do not change the number of times increase thereby therefore be durable to make; In addition, because the spindle shell is all-in-one-piece, therefore install and change button pipeloop inconvenience.

At existing problem in the above-mentioned prior art, a purpose of the present utility model provide a kind of can bear the high-tension reel for yarn around the paper tube type Winding spindle, specifically, this Winding spindle can be avoided taking place contraction distortion owing to paper twine pipe mid portion and make the problem of a yarn under pulling out not when having the winding yarn of high-tension.

Another purpose of the present utility model provides a kind of the minimizing and changes the number of times of detaining pipeloop and install and remove the paper tube type Winding spindle that the button pipeloop can bear high yarn tension easily.

For achieving the above object, the paper tube type Winding spindle that bears high yarn tension of the present utility model comprises: one has the spindle shell of button pipeloop, one passes ten spindle blades of described spindle shell, two rolling bearings that are installed in respectively on the described spindle two ends, one is arranged on the hold-down screw on the described spindle blade front end, two are located at the seal cover on the described bearing outside respectively, balance or cancel each other and be located at bearing cap on the bearing cone, and a elastic washer on the described spindle blade that is set between the front bearing retainer outside and the described hold-down screw, the inwall of described spindle shell forms a frustum of a cone at the inboard place of described bearing and describes oil pocket; Its characteristics are, described spindle shell by relative scarf one before flyer body and a back flyer body form, also be included in an integrally formed intermediate supports ring on the excircle of scarf end of one of described forward and backward flyer body.

The problem that a yarn can not be pulled out down owing to adopted described intermediate supports ring structure, spool after bearing yarn tension, can not produce the internal diameter contraction distortion, thus guarantee the tube yarn that obtains to conform to quality requirements, and improved the efficient of doff; While has reduced because of changing the number of times of the dismounting spindle of detaining pipeloop thereby therefore improved because the button pipeloop has used durable rubber to make its service life; Because flyer is two sections scarf structures, therefore mounting or dismounting button pipeloop is very convenient simultaneously.

Below specify the purpose of this utility model and characteristics by a most preferred embodiment of the present utility model.

Fig. 1 is half longitudinal section of an embodiment of the paper tube type Winding spindle of anti-high yarn tension of the present utility model.

As shown in the figure, the utility model paper tube type Winding spindle comprises: a flyer body 9 and a back flyer body 7 before one.The rear end of flyer body 9 forms one along axis and is recessed groove before described, then form an outer groove on the front end periphery of flyer body 7, so that can locate by relative scarf with the front end of back flyer body 7 rear end of preceding flyer body 9, on the periphery of preceding flyer body 9 described rear ends, form an intermediate supports ring 10, the nearly middle part of described back flyer body is embedded the button pipeloop 8 of a durable rubber, adopt polyurethane rubber to make in this example, also comprise: one pass mutual scarf before, the spindle blade 1 of back flyer body, be installed in the scroll forward and backward bearing 12 on the two ends of spindle blade 1 respectively, 4, be located at described bearing 12 respectively, go forward in 4 outsides,

back seal cover

13,3, support respectively and be located at front and back bearings 12, before on 4 inner rings,

rear bearing cover

11,2, one is located at hold-down screw 15, on the front end of spindle blade 1 is set in elastic caoutchouc packing ring 14 on the spindle blade part between front bearing retainer 11 outsides and the hold-down screw 15; Forward and backward

flyer body

9,7 forms Frusto-conical appearance oil pocket 5,4 respectively on the inwall at place, the inboard of forward and backward bearing 12,4.

As mentioned above, a because integrally formed intermediate supports ring 10 on the rear end periphery of the preceding flyer body 9 of one of front and back flyer body, therefore after the paper twine pipe is provided on the spindle shell (front and back flyer body), can increase the ability of bearing yarn tension greatly, the contraction that can avoid taking place the spool internal diameter diminishes and bites the spindle small end and pull out the not situation of doffing yarn; In addition, the spindle housing is divided into two sections, the structure of promptly forward and backward

flyer body

9,7, the dismounting that can be convenient to detain pipeloop 9, simultaneously since button pipeloop 9 adopted as polyurethane in this class durable rubber, thereby improved its service life and reduce and change the button pipeloop and the number of times of dismounting spindle.

Claims

1. paper tube type Winding spindle that can bear high yarn tension, comprise that one has the spindle shell of button pipeloop, one passes the spindle blade of described spindle shell, two rolling bearings that are installed in respectively on the described spindle blade two ends, two are located at the seal cover on the described bearing outside respectively, balance or cancel each other and be located at bearing cap on the bearing cone, one hold-down screw and that is arranged on the described spindle blade front end is set in outside the front bearing retainer and the elastic washer on the spindle blade between described hold-down screw, and the inwall of described spindle shell forms a frustum of a cone at the inboard place of described bearing and describes oil pocket; It is characterized in that described spindle shell is made up of a preceding flyer body and a back flyer body of relative scarf; Also be included in integrally formed intermediate supports ring on the excircle of scarf end of one of described front and back flyer body.
