Abstract

The utility model relates to an electromagnetic yarn balancing roller which comprises a roller housing, an electric core and a built-in circuit. The electric core and the built-in circuit are embedded into the roller housing, and the roller housing is coaxial with the electric core. The electromagnetic yarn balancing roller is characterized in that an outer layer and an inner layer of the electric core are respectively a magnet group and a coil, a middle shaft is fixedly installed on the coil axis, one free end of the middle shaft extends out of the roller housing, and the electric ore is electrically connected with the built-in circuit. The defects existing in the prior art are overcome. A generator principle is adopted to design the electromagnetic yarn balancing roller which is capable of immediately adjusting yarn transformation tension and controlling brake force through the electric core embedded inside the roller housing, the higher the yarn motion speed is, the roller brake force is larger, the slower the yarn motion speed is, and the roller brake force is small. The electromagnetic yarn balancing roller has a function of achieving yarn tension fluctuation and is high in automation degree, flexible in response, real-time and quick.

Description

Electromagnetism yarn balance roller

Technical field

The utility model relates to a kind of spinning equipment accessory, relates in particular to a kind of electromagnetism yarn balance roller.

Background technology

On bobbin-winding machine and doubler, yarn conventionally can be by high-speed winding or unwinding, yarn movement process is because the friction force between each parts and yarn on the mutual winding of yarn and machine on unwinding wound packages, the yarn of high-speed motion there will be yarn tension unstable, even occur that yarn operation is made a pause and the situation of broken yarn, also can affect the moulding after yarn package simultaneously, in order to relax yarn tension, make its smooth running, reduce the amplitude of tension fluctuation, need between unwinding package and moulding package, increase yarn balance roller, yarn can be wound by pulsation-free, reduce broken yarn, improve Forming Quality.

Utility model content

The utility model has overcome the deficiencies in the prior art, and a kind of electromagnetism yarn balance roller simple in structure is provided.

For achieving the above object, the technical solution adopted in the utility model is: electromagnetism yarn balance roller, comprise: roller housing and be embedded in battery core and the built-in circuit of described roller enclosure interior, described roller housing is coaxial with described battery core, it is characterized in that, the skin of described battery core and internal layer are respectively group of magnets and coil, and described coil axis is installed with axis, described axis one free end stretches out described roller outside, and described battery core is electrically connected with described built-in circuit.

In preferred embodiment of the utility model, described built-in circuit is by forming for resistor or indicator lamp forms or resistor and indicator lamp form jointly.

In preferred embodiment of the utility model, on described roller enclosure interior axis, be also provided with bearing, described bottom bracket axle is on described bearing.

In preferred embodiment of the utility model, described roller housing is that two ends radius is large, the cylinder that middle radius is little, and described roller housing lateral edge is level and smooth camber line.

In preferred embodiment of the utility model, in the middle of described roller housing, skin is surrounded by a circle wearing layer, and described wearing layer outside face smoothly docks with described roller housing outer surface.

In preferred embodiment of the utility model, described axis stretches out one section of described roller outside and is provided with screw thread.

In preferred embodiment of the utility model, described group of magnets is fixedly embedded in described roller enclosure interior, and described coil can be arranged in described group of magnets in relative rotation.

The utility model has solved the defect existing in background technology, the utility model adopts generator principle to design aly can adjust yarn changing tension force immediately, by being embedded in the braking force of battery core control roller of roller enclosure interior, yarn movement speed is faster, and roller braking force is larger, yarn movement speed is slower, roller braking force is less, and the utility model can be realized the function that reduces Yarn tension fluctuation, and degree of automation is higher, be quick on the draw, real-time.

Detailed description of the invention

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As depicted in figs. 1 and 2, a kind of electromagnetism yarn balance roller, comprise the cylindricality roller housing 2 that radius large middle radius in two ends is little, the lateral edges camber line of roller housing 2 is comparatively level and smooth, like this design, yarn 20 is not easy slippage from roller after roller one circle, can not damage yarn 20, in order to allow roller, just face can be very soon by thread wear, and roller housing 2 outside faces are surrounded by a circle wearing layer 16 yet, wearing layer 16 outside faces dock with roller housing 2 outer surface smoother, can not cause damage to yarn 20.

Roller housing 2 inside are provided with battery core 4, battery core 4 is coaxial with roller housing 2, preferably battery core 4 skins are group of magnets 8, battery core 4 internal layers are coil 10, coil 10 central axis go out to fixedly mount axis 12, axis 12 1 free ends stretch out roller housing 2 outsides, axis 12 is enclosed within on the bearing 14 being provided with in roller housing 2, axis 12 can together rotate with respect to group of magnets 8 with coil 10, group of magnets 8 is relatively fixing with respect to roller housing 2, little electrical generator of group of magnets 8 and the common composition of coil 10, it is battery core 4, preferably battery core 4 is electrically connected indicator lamp and resistor, operating personal can judge yarn 20 rotative speeds and acceleration/accel according to the brightness of indicator lamp, yarn 20 rotative speeds are too fast, yarn 20 drives roller housing 2 and group of magnets 8 to rotate also too fast with respect to coil 10, now electromagnetic force is also larger, suitably hinder roller rotation, reduce too fast yarn 20 speed of yarn 20 running velocity balances, otherwise, yarn 20 running velocitys are excessively slow, the electromagnetic force that hinders roller rotation is less, yarn 20 running velocitys are comparatively steady on the whole like this, yarn 20 tension fluctuations are less, also more good to the package quality of yarn 20, screw thread 18 on axis 12 can or be with female parts to be used in conjunction with nut, for fixing roller.

When the utility model work, yarn 20 is around roller after one week, drive roller housing 2 and group of magnets 8 to rotate, coil 10 is relative with axis 12 fixing, because group of magnets 8 produces electro-motive force with the relative motion of coil 10, no matter be that yarn 20 drives roller rotative speed too fast or excessively slow, battery core 4 all can be adjusted yarn 20 running velocitys automatically because of the electromagnetic force producing, and the brightness meeting of indicator lamp is because running velocity and the acceleration/accel of yarn change.

Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine technical scope according to claim scope.
