The design of the small * is reasonable, the technological properties are good, the quantity of roiled silk is large, the inherent quality and the air and water permeability of the raw silk are good, the labor intensity of workers is alleviated, the raw silk material is saved, and the productivity is increased.

Description

Concave reel

The device of coiling raw silk when the utility model relates to a kind of filature, it is one of critical piece of silk reeling industry reeling machine.

Existing both at home and abroad little

Two kinds of basic structures are arranged: a kind of is that polygonal is little

, another kind is that cydariform is little

1, polygonal is little

(compile textile industry publishing house and publish the 141st page of Fig. 6-7 in December, 1985 referring to " the theoretical and management of automatic silk reeling machine " Hangzhou textile machinery factory, Hangzhou Silk Mill of Xinhua), its formation is: have ten

The angle, it and silk sheet contact-making surface be shape linearly,

The angle with Connect by gusset between the core,

The core two ends are provided with each one in the interior cover of separate type, are provided with spring leaf between the two interior covers, and power transmission shaft passes interior trepanning, and the frictional force between dependence axle and the spring leaf makes little

Revolution, at this moment,

The angle surface raw silk of just reeling; Its weak point is: a, rectilinear ten

The angle, because It is limited that angle and gusset bear the pressure of a sheet, and the silk amount too much can make its fracture, so the undrawn yarn amount is few; Simultaneously, also be subjected to its structural limitations, when increasing silk sheet width, wire ring easily to

The angle small end is deviate from, and generates bad silk; Tension variation is big when b, strand coiling, easily causes a sheet tension force inhomogeneous, can influence the correctness of perception when particularly adopting denierer to control raw silk size to automatic silk reeling machine, simultaneously, can not adapt to high-speed winding; In the c, separate type cover with

The core joint is difficult for coupling, if tight slightly, then after spring leaf wore and tore, it was inconvenient to change dismounting, if loose partially, then in use interior cover easily comes off.2, cydariform is little (referring to the same " the theoretical and management of automatic silk reeling machine ".The 142nd page of Fig. 6-8), its formation is: do not have

The angle, circumferential rounded cancave cambered surface, arc chip gusset with Core is connected,

The interior cover of core also is a separate type, respectively establishes one of spring catch, relies on the frictional force between axle and the spring catch to make little

Revolution; Its weak point is: a, owing to do not have

The angle, when occurring broken end in the winding process, operator's change is abandoned the silk difficulty, and can cause the raw silk waste therefrom, and is simultaneously, because spring catch pressure is big, when change is abandoned thread, little

Be difficult for falling back, workman's operation is effort very, has increased labour intensity; B, because this is little

Be closed arc surface with silk sheet contact-making surface, so hot-air is difficult for circulation and enters a sheet inside during its filature, influence is dry, very during the light dewing, causes dewing irregular again, so in during the rereeling unwinding, the internal layer broken end is many, influences production efficiency, increased labour intensity.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and provide that a kind of coiling raw silk amount is many, the raw silk inherent quality is good, ventilative, good water permeability, arcs of recesses is little easily for operation

The purpose that the utility model proposed can be achieved through the following technical solutions: this is little The angle is arcs of recesses with the contact-making surface of silk sheet, and is little Small end links to each other with the seal wire ring.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Following the utility model will further describe by embodiment.

Referring to Fig. 1, this is little

Comprise

Angle 1,

Core 4 and gusset 3,

Be connected by gusset 3 between angle 1 and the core 4, gusset 3 adopts cross wide cut degree structures, Angle 1 is arcs of recesses with the contact-making surface of silk sheet,

Angle 1 small end and an annulus join, and form seal wire ring 2,

Angle 1 big end joins with another annulus, and formation stops

Ring 5; Present embodiment is little Circumferentially uniform 20

Angle 1, wherein ten is to have gusset Angle 1 ', other ten are no gusset

Angle 1 ", be between them alternately that (promptly one has gusset

Angle 1 ', a no gusset again Angle 1 ", one gusset is arranged again

Angle 1 ' ... be provided with so at interval), certainly, Angle 1 has been gusset

Angle 1 ' also be fine. Interior cover 8 in the core 4 is designed to monoblock type, and the one end can be designed to protective cover 6, when interior cover 8 passes

Behind the core 4, the other end can be threaded for 8 one-tenth with interior cover by end cover 9, in the interior cover 8 spring leaf 7 is installed.

When filature is produced, In axle (power transmission shaft) passes trepanning borrow spring leaf 7 and between centers (or in having concurrently cover 8 with

4 in core) frictional force comes transmission little

, make its revolution coiling raw silk.

This is little

Monoblock type in the cover 8, its with

4 in core both can adopt tight fit, also can adopt movingly, when interior cover 8 with When 4 in core adopts tight fit,

Frictional force between axle dependence and the spring leaf 7 makes little Revolution; When interior cover 8 with When 4 in core adopts movingly, Axle rely on spring leaf 7 and in cover 8 with The frictional force that core is 4 makes little Revolution.

In the present embodiment, this is little

In Angle 1, seal wire ring 2, gusset 3,

Core 4 and stopping Ring 5 designs are in aggregates, available engineering plastics single injection-molded.Certainly, also available metal is made.

The utility model compared with prior art has following remarkable advantage: 1, becauseThe angle is arcs of recesses, and forms wire guide ring with its small end, so, increased little

Bearing capacity, a silk sheet width can increase (but not producing bad silk), and is little

The undrawn yarn amount can increase, and has improved labor productivity; And little

Winding tension more even; 2, becauseThe angle does not form closed arc surface with a silk sheet contact-making surface, so, ventilative, water permeability is good, be conducive to a sheet drying and evenly reach the infiltration of vacuum dewing evenly; The formation of wire guide ring makes the rereeling unwinding smooth, has reduced workman's operating time, and has alleviated labour intensity, has saved the raw silk raw material. 3, owing to adopt the monoblock type inner sleeve, and with being threaded, this structure make inner sleeve with

The transmission of axle is turned to tighter and tighter, so it can not come off, and after spring leaf wearing and tearing, the dismounting transposing easily; Simultaneously, inner sleeve is monoblock type, can guarantee concentricity requirement, makes little

Smooth running is conducive to correctly control raw silk size; And since inner sleeve with

Not only can adopt tight fit between core, but also can adopt movingly, so when in silk reeling process, needing change to abandon thread, little

It is flexible, light to fall back, and has alleviated labour intensity. 4, this is little

{。##.##1},

The angle,

Core, gusset, wire guide ring and stopEncircle available engineering plastics one-shot forming, easily manufactured, any surface finish; The assembling of inner sleeve conjunction, dismounting are easily; Whole little

Simple in structure, novel, processing performance is good, and is applicable to automatic silk reeling machine and the multiends reeling machine of various models, widely applicable.
