The rollers are connected by a gear pair, and the direction of the linear velocity has the same size. The gear pair and a system changeover gear compose a drawing mechanism, the rollers are fixed on a support foot through an aligning bearing, and the upper side of a block bar base is provided with a block bar which prevents a continuous-filament pony roll from colliding and inversing mutually when the continuous-filament pony roll is operated. The active continuous-filament output mechanism is also provided with an adjustable positioning device which is used for controlling the output position of the continuous-filament, and the adjustable positioning device can be arranged on a member of the used machine and the use of the member has no influence. The installation length of the mechanism can be lengthened or shortened according to the need, and the support foot can simply make the mechanism and the selected machine connected together.

Description

Long filament is output mechanism initiatively

The utility model relates to the traditional spinning machine of a kind of confession, twisting machine spins the long filament active output mechanism that elastomeric yarn is used.

Traditional spinning machine twisting machine with pull mode with the long filament unwinding after with fiber yarn and incompatible production cladded yarn, but this mode has following defective:

1. be difficult to quantitatively control the long filament output speed;

2. in whole process of production, the tension force of long filament is inhomogeneous;

3. the cladded yarn of Sheng Chaning reveals core easily.

The purpose of this utility model is to provide a kind of can initiatively export long filament, can quantitatively control thread-tension in long filament output speed, the production process evenly and the cladded yarn of being produced and the bag long filament output mechanism initiatively of twisting thread and being difficult for revealing core.

Another purpose of the present utility model is to provide a kind of long filament active output mechanism that just can produce cladded yarn and bag twist yarn with at present traditional spinning machine and twisting machine simple combination that needs only.

The purpose of this utility model is achieved in that provides initiatively output mechanism of a kind of friction-type long filament, it has the forward and backward roller of the horizontal positioned that a pair of diameter is identical, the surface is very smooth, this is connected by gear pair roller, linear velocity direction size is identical, and gear pair and system changeover gear constitute drafter.Roller is fixed on the stand-off by self-aligning bearing, has one to prevent the gear stick that the long filament bobbin collides mutually and lodges in the running, and gear stick is installed on the gear stick base.The adjustable locator that also has a control long filament outgoing position, locator can be installed on the parts of machine at place, and the installation length of mechanism can extend or shorten as required, and stand-off can be simply links together this mechanism with required machine.

Because between forward and backward roller of the present utility model and the long filament bobbin is frictional drive, guaranteed that therefore the long filament bobbin is initiatively exported long filament with the surface of roller linear velocity of setting and output speed keeps stable, can not change with the vary in diameter of bobbin.In addition,, can guarantee that long filament is in the centre of gyration, make it twist with the fingers the width of cloth and equal zero that fiber or yarn then clad around long filament, thereby form cladded yarn or bag twist yarn owing to used locator.In addition, owing to the utility model can be simply can be linked together with traditional required machine, therefore, be to save foreign exchange, for the range of application that enlarges homemade traditional spinning machine provides new approach, also provide new method for production cladded yarn, bag twist yarn.

Below in conjunction with Fig. 1 with a preferred embodiment the utility model is specifically described.

Fig. 1 is the initiatively schematic perspective view of output mechanism of long filament of the present utility model.

Fig. 2 is that the utility model is used for the structural scheme of mechanism that twisting machine (B601, A631) comes coated yarn spinning.

Fig. 3 is the schematic diagram of correlation between explanation roller of the present utility model and the machine delivery roller.

See also Fig. 1 earlier.The utility model is an initiatively output mechanism of friction-type long filament, and it is as follows that it forms structure: the forward and backward roller 4,7 of the horizontal positioned that a pair of diameter is identical, the surface is very smooth is connected by gear pair, and linear velocity direction size is identical.Gear pair and system changeover gear 12 constitute drafter 12a, and the power of drafter 12a is taken from power or other independent power source of place machine.Roller 7,4 is fixed on the stand-off 13 by self-aligning bearing 2, has one to prevent long filament bobbin 1 gear stick 3 of collision and lodging mutually in the running, and gear stick 3 is installed on the gear stick base 6.The adjustable locator 11 (referring to Fig. 2) that also has a control long filament outgoing position.Locator 11 can be installed on the parts of machine at place, and can not influence the use of these parts, and the installation length of mechanism can extend or shorten as required, and stand-off 13 can be simply links together this mechanism with required machine.

See also Fig. 2 and Fig. 3 below, be introduced on B601 and A631 twisting machine, using the technology of the utility model coated yarn spinning.

As shown in Figures 2 and 3, the utility model links to each other with yarn-twisting machine by the stand-off 13 that is fixed on the yarn-twisting machine column 5, and locator 11 of the present utility model is fixed on the frame, and the power of drafter 12a is taken from yarn-twisting machine delivery roller 10.Long filament bobbin 1 is placed between the front roller 7 and rear roller 4 of horizontal positioned of the present utility model, has gear stick 3 to separate between bobbin, collides at the volley or lodges to prevent the long filament bobbin.Gear stick 3 is installed on the gear stick base 6.Gear stick base 6 is fixed on the stand-off 13, adjusts the change gear 12 of drafter 12a, makes the linear resonance surface velocity of front roller 7 and rear roller 4 and the speed difference of twisting machine delivery roller 10 (filament drawing coefficient) reach designing requirement.After the driving, the long filament bobbin of putting 4 of front roller 7 and rear rollers 1 rotates output long filament with the rotation of rear roller 4 by designing requirement with front roller 7, long filament enters pincers mouth 9 through locator 11 with yarn 8, adjusts the locator 11 that is fixed on the twisting machine, makes long filament be in the centre of gyration.Yarn 8 is twisted by steel traveler after long filament goes out pincers mouth 9, because long filament is in the centre of gyration, its sth. made by twisting width of cloth equals zero during twisting, therefore is enclosed in the inside tightly by yarn, forms the cladded yarn that does not reveal core.

By those cladded yarn and bag twist yarns that uses homemade wool spinning frame, twisting machine and cotton spinning frame, twisting machine of the present utility model to spin, the examination and test of products is the result show: resultant yarn tension draft multiple meets the requirements and tension stability, and long filament does not have the core of revealing phenomenon.
