Abstract

The utility model discloses a mechanical tight spinning drafting mechanism, relates to a drafting mechanism used with a ring spinning frame, and particularly belongs to the mechanical tight spinning drafting mechanism. The mechanical tight spinning drafting mechanism is provided with a three-roller drafting device including three pairs of rollers which are a pair of pull-in rollers, a pair of intermediate rollers and a pair of output rollers; and a yarn guide leather roller 7 and a bundling component 8 are arranged in front of the output rollers. The mechanical tight spinning drafting mechanism is characterized in that the diameter of a lower output roller 6 is 30 to 60 mm; the inclined angle of a roller stool is 30 DEG to 40 DEG; the operation route of a yarn from the yarn bundling component 8 to a position between the lower output roller 6 and the yarn guide leather roller 7 is a straight line, which can effectively reduce back-surrounded arcs. Therefore, the mechanical tight spinning drafting mechanism has the advantages of reasonable structure, low energy consumption, little end breakage, and high spinning quality.

Description

Mechanical type compact spinning drafting mechanism

Technical field

The utility model relates to a kind of and the matching used drafter of ring spinning frame, particularly belongs to a kind of mechanical type compact spinning drafting mechanism.

Background technology

Compact spinning is a kind of novel yarn resultant yarn technology that rise in the later stage nineties in last century Europe, thereby effectively reduces resultant yarn filoplume raising single thread force because of reducing twist triangle zone, and yarn quality obviously is better than the traditional ring spinning yarn.Compact spinning apparatus is mainly suction type and mechanical type both at home and abroad at present.Suction type need consumed power in the running, and apparatus for collecting needs periodic cleaning, the operating cost height owing to increased a negative-pressure air fan; Mechanical type is installed and is transformed conveniently, do not have extra energy consumption, but there is reverse arc of contact in twist triangle zone, and broken end is many than suction type.

What illustrate in Fig. 1 is the drafting system of existing common ring spinner, and it comprises one, and to draw in roller right, drawing in pressure roller 3 and draw in lower roll 4 and form by the feeding ribbon.Right along the intermediate calender rolls of forming by middle pressure roller 2 and middle lower roll 5 on the direction of motion of ribbon, and by this roller to guiding two aprons runnings.Draw in roller to and intermediate calender rolls between for the preliminary draft district of ribbon.It is right to be provided with the outlet roller that output press roll 1 and output lower roll 6 form at the output of three roller drafting devices.Intermediate calender rolls to and outlet roller between be the main drawing area of ribbon, ribbon becomes desired fineness through the drawing-off of preliminary draft district and main drawing area.Drawing-off ribbon twist with the fingers into the finished product yarn by means of spinning rotation, with the interface of the right clamping line of outlet roller on constitute the twist triangle zone of spinning, as far as possible little for what twist triangle zone was controlled, at outlet roller to a beaming device preceding is set, as shown in Figure 2, before main drawing area, increased boundling parts 8 and output lower roll 7, ribbon has been carried out the boundling guiding, compressed the back by the guide roller and twist with the fingers into the finished product yarn by the spinning rotation by this beaming device.But install the magnetic force compact spinning apparatus additional in existing three roller drafting devices after, the place can form reverse arc of contact at the output lower roll, influences yarn quality, increases end breakage rate.

Summary of the invention

The purpose of this utility model promptly is to provide a kind of new mechanical formula compact spinning drafting mechanism, to overcome the problem that existing machinery formula compact spinning exists, eliminates reverse arc of contact, reduces Yarn break, improves yarn quality.

Mechanical type compact spinning drafting disclosed in the utility model mechanism, have three roller drafting devices, promptly comprise by draw in pressure roller 3 and draw in that lower roll 4 forms draw in roller to, the intermediate calender rolls formed by middle pressure roller 2 and middle lower roll 5 to, by output press roll 1 with to export the outlet roller that lower roll 6 forms right; Intermediate calender rolls is set pin 10 to guiding two apron runnings in the following apron; Outlet roller is to preceding being provided with guide roller 7 and boundling parts 8; It is characterized in that the diameter of output lower roll 6 is 30～60 millimeters; The angle of inclination of roller stool 9 is 30 °～40 °; Yarn from boundling parts 8 to the running route between output lower roll 6 and the guide roller 7 linearly.

Because lower roll of the present utility model has bigger diameter with respect to the lower roll of the drafting system of routine, thus pressurization roller and guide roller easy arrangement, and the boundling parts can be arranged between two rollers simply, and can reduce reverse arc of contact.Roller stool of the present utility model has littler angle of inclination with respect to the roller stool of conventional drafting system, can further reduce reverse arc of contact.Therefore, the utlity model has that reasonable structural arrangement, energy consumption are little, little breakage, characteristics that spinning quality is high.

Description of drawings

Accompanying drawing partly discloses specific embodiment of the utility model, wherein:

Fig. 1, the drafting system schematic diagram of the ring spinner of prior art;

Fig. 2, the mechanical type compact spinning drafting device schematic diagram of prior art;

Fig. 3, structural representation of the present utility model;

Fig. 4, the structural representation of the utility model output lower roll.

The specific embodiment

As shown in Figure 3, the utility model is taked three roller drafting devices, and parts constitute with arrangement roughly the same with prior art.But adopted the less roller stool 9 in angle of inclination, and diameter is obviously greater than the output lower roll 6 of common roller.In the present embodiment, roller stool 9 angles of inclination are 36 °, and output lower roll 6 diameters are 60 millimeters.In the mechanical type compact spinning drafting device of prior art shown in Figure 2, yarn forms tangible reverse arc of contact at boundling parts 8 to output lower roll 6 and guide roller 7 places.And as shown in Figure 3, the utility model institute yarn, is involved between output lower roll 6 and the guide roller 7 then by boundling parts 8, and institute is a straight line through route.Can find out obviously relatively that thus the utility model can be eliminated reverse arc of contact effectively, thereby reduce broken end, improve yarn quality.

Though the utility model has adopted and the visibly different output lower roll 6 of prior art, pressurization roller 1 and guide roller 7 can adopt common ring ingot spinning roller and not need special making, thereby effectively reduce production costs.

As shown in Figure 4, in order to be applicable to existing mill type modification, output lower roll 6 is only at local location, and the working face 6-1 position that promptly contacts with yarn, enlarged diameter to 30～60 millimeter, all the other positions then still keep 25 millimeters or 27 millimeters of diameters in the national standard.In addition, for reducing to export the rotary inertia of lower roll 6, strengthen the stability of its running then, the output lower roll 6 in the present embodiment is established groove 6-2 on the corresponding roll body of working face 6-1, to reduce the moving-mass at this position.
