Abstract

The utility model discloses a compact spinning nesting device of a ring frame. The utility model comprises a double-rubber roller frame, a front rubber roller and an output rubber roller, wherein the front rubber roller and the output rubber roller are respectively arranged on the double-rubber roller frame. The utility model is characterized in that a buncher is arranged between the front rubber roller and the output rubber roller; an elastic pressurizing element is arranged on the buncher. Because the utility model is pressurized by using the elastic pressurizing element, structure is simple and pressurization is stable. Thus, a roller drive and an air sucking systems are not required for being added on the ring frame and the utility model is particularly suitable for an old ring frame. Compact spinning can be realized just by a way that an original delivery roller is changed into the nesting device supplied by the utility model, and thus, equipment modification, dynamic force and handling cost is saved. Because elastic pressurization and positioning are used, the utility model has the advantages of convenient operation, reliable use and noise reduction.

Description

A kind of tight-spinning collecting device of ring throstle

Technical field

The utility model relates to the tight-spinning collecting device of the spinning engineering in the caused by spinning industrial production, particularly ring throstle.

Technical background

Traditional ring throstle drafting system, at the yarn of front roller nip line output, the time spent is done in the twisting that is subjected to turning round air ring, and the defective that exists twist triangle zone on the front roller surface is the main cause that spun yarn produces filoplume.Now confirm, before yarn is finished the drawing-off effect and is implemented the twisting effect, increase apparatus for collecting and can make the yarn structure tight, after front roller output, eliminated the defective of the twist triangle zone of traditional ring throstle more basically, reduce fuzzy yarn, be called closely and spin.At present more existing apparatus for collecting are applied to fine spining machine, but structure more complicated (Chinese patent 03237190.X authorizes publication number CN2623717Y) need increase roller and air draft system on fine spining machine, increase the consumption of management and power simultaneously.

Summary of the invention

The purpose of this utility model is at the apparatus for collecting complex structure, need increase roller and air draft system on fine spining machine, increases the defective such as consumption of management and power simultaneously and apparatus for collecting that a kind of ring throstle of providing closely spins.

The purpose of this utility model is achieved in that

The apparatus for collecting that a kind of ring throstle closely spins, comprise two rubber roll framves, preceding rubber roll, output rubber roll, preceding rubber roll, output rubber roll are located at respectively on two rubber roll framves, and characteristics are to be provided with buncher between preceding rubber roll, the output rubber roll, and the buncher top is provided with the elasticity pressing means.

Described buncher upper center is provided with conical bore, bottom and is provided with that semicircle tubaeformly gathers the chamber, the bottom surface is an arc surface.

Described chamber two sides of gathering are offered guiding gutter respectively.

Described elasticity pressing means can be to add making leaf spring or pressing spring assembly, is arranged with the pressurization jag on the elasticity pressing means.

The utility model is owing to adopt the spacing and pressurization of elasticity pressing means, make features simple structure, it is more stable to pressurize, need not on fine spining machine, increase roller transmission and air draft system, especially adapting to old machine uses: the apparatus for collecting that only need change former delivery roller into the utility model provides just can be realized compact spinning, has saved scrap build, power and management cost greatly.Owing to adopt elasticity pressing means location, make easy to operate use reliable, easily manufactured, also reduced noise.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment one:

Consult Fig. 1,2,3, the utility model comprises that two rubber roll framves 1, preceding rubber roll 2, output rubber roll 3, buncher 4, elasticity pressing means 5 constitute (call in the following text and add making leaf spring), geometrical clamp 6 and hold-down screw 7 and form by adding making leaf spring; Preceding rubber roll 2, output rubber roll 3 are fixed on two rubber roll frame 1 front and back two sides, buncher 4 is placed in the centre of two rubber roll frame 1 two sides and preceding rubber roll 2 and output rubber roll 3, add making leaf spring 5 and be fixed folder 6 through hold-down screw 7 and be fixed in two rubber roll frame 1 middle parts, the pressurization jag 8 that adds making leaf spring 5 two sides contacts with buncher 4 upper ends central authorities conical bore 9 multiple degrees of freedoms cooperations; Buncher 4 bottoms are provided with the tubaeform chamber 10 of gathering of semicircle, and the face 12 that buncher 4 is positioned at the bottom is the arc surface identical with front roller curvature.

The axle core of rubber roll 2 is connected with the pressurized cradle of fine spining machine drafting system routinely before of the present utility model, when working, fine spining machine, force the preceding rubber roll 2 of apparatus for collecting closely to contact enforcement yarn effectively gripping and transmission with output rubber roll 3 and front roller because pressurized cradle presses down; Buncher 4 before being positioned in the middle of rubber roll 2 and the output rubber roll 3 makes the circular-arc face 12 in buncher 4 bottoms be adjacent to the front roller surface under the effect that adds making leaf spring 5, make buncher 4 bottom center gather chamber 10 and form the closed area with the front roller surface, when yarn therefrom passes through, be the tubaeform qualification of gathering curved surface of semicircle from big to small owing to gather chamber 10, make yarn retrain intensive gradually in this closed area, form tight yarn, reach the effect of compact spinning; Adding making leaf spring 5 is fixed folder 6 through hold-down screw 7 and is fixed on two rubber roll frame 1 middle parts, the pressurization jag 8 of its two side cooperates with central conical bore 9 multiple degrees of freedoms in buncher upper end and adds press contacts, making between buncher 4 and preceding rubber roll 2 and the output rubber roll 3 has appropriate gap, with rubber roll before guaranteeing and the normal transmission of output rubber roll.

Embodiment two:

Consult Fig. 4, elasticity pressing means 5 can be the pressing spring assembly, is made of pressurizing frame 16, pressing spring 14, pressurizing chamber 15 and pressurization prodger 13; Pressurizing frame 16 is pressed abd fixed on pair rubber roll frame 1 middle parts through hold-down screw 7, settles pressing spring 14 in the pressurizing chamber 15 of pressurizing frame 16 2 sides, to compress pressurization prodger 13, makes it to contact with the central conical bore 9 multiple degrees of freedoms cooperation in buncher 4 upper ends.

Chamber 10 2 sides of gathering in the buncher 4 of the present utility model offer guiding gutter 11, its objective is the air-flow that is obstructed between shunting buncher 4 and preceding rubber roll 2 and the output rubber roll 3, and the air-flow that prevents to be obstructed is taken fiber in the yarn out of yarn, stablizes spinning process.
