Detailed Description

The first embodiment is as follows:

referring to fig. 1-5, a yarn guide for textile machinery comprises an L-shaped rod 1 and a winding coil 4, wherein an installation plate 2 is arranged on the L-shaped rod 1, a plurality of bolts are arranged on the installation plate 2, the installation plate 2 can enable equipment to be easily installed on textile equipment, a large space is not occupied, the use value of the equipment is increased, the yarn guide further comprises a rotating rod 3 inserted at the axial position of the winding coil 4, the rotating rod 3 penetrates through one end of the L-shaped rod 1, and the rotating rod 3 is rotatably connected with the L-shaped rod 1;

a plurality of bumps 5 are fixedly arranged at one end of the rotating rod 3 far away from the winding coil 4, and the bumps 5 are arranged at equal intervals;

an opening box 6 fixed below the rotating rod 3 through bolts, wherein the opening box 6 is filled with non-Newtonian fluid 7;

and a fixed rod 8 fixedly arranged on the L-shaped rod 1, wherein a first lead wheel 9 is arranged on the fixed rod 8.

The yarn can drive winding coil 4 and dwang 3 synchronous rotation at the pulling in-process, when the yarn stopped to move, winding coil 4 still has inertia, but because inside lug 5 immerses non-Newtonian fluid 7, will make non-Newtonian fluid 7 become the solid when lug 5 rapid draing, receive great resistance, if lug 5's rate of movement will be big more greatly receiving the resistance, consequently lug 5's removal can receive the restriction, consequently dwang 3 will stop fast, prevent that the yarn on the winding coil 4 is loose to knot, be favorable to improving work efficiency.

Because some textile machinery's on the market work efficiency is higher, the speed of inlet wire is very fast, consequently when the yarn of spurring suddenly, can break the yarn, consequently set up buffer gear for prevent the yarn fracture on the coil 4, buffer gear includes the slide bar 10 of slip insertion establishing in L shape pole 1 one end, and the slide bar 10 is close to the fixed movable rod 11 that is provided with in one end of coil 4, be provided with second lead wire wheel 12 on the movable rod 11, and be provided with reset spring 13 on the slide bar 10.

In actual use, the yarn bypasses the first lead wheel 9 and the second lead wheel 12, when the yarn is pulled, the second lead wheel 12 can drive the sliding rod 10 to move towards the direction far away from the winding coil 4 under the action of the pulling force, and the return spring 13 is compressed, so that the tension applied to the winding coil 4 in the process is small, the slow rotation can be realized, and the yarn breakage can not be caused.

Afterwards, when the yarn is not under the pulling force, the reset spring 13 will move the sliding rod 10 to the direction close to the winding coil 4, and slowly pull out the yarn on the winding coil 4, so repeatedly, the whole process of the slow rotation of the winding coil 4 will not cause the winding coil 4 to suddenly receive the larger pulling force, and the yarn breakage can be effectively prevented.

The lateral wall that dwang 3 and coil 4 contacted is provided with mounting 19 for fixed coil 4, mounting 19 adopt a plurality of metal shrapnels, and a plurality of metal shrapnels equidistant setting.

In use, because the shape of the winding coil 4 is large or small, the metal elastic sheet is arranged outside the rotating rod 3, so that the inner surface of the winding coil 4 can be abutted against the metal elastic sheet, mutual rotation between the winding coil 4 and the rotating rod 3 is effectively prevented, the winding coil 4 can also stop rotating when the rotating rod 3 stops rotating, the application range of equipment is increased, and the practical value is increased.

Still include stop gear, be used for preventing dwang 3 to rotate, stop gear is including the fixed U-shaped plate 14 that sets up under dwang 3, and the fixed branch 20 that sets up on slide bar 10, and it is provided with gag lever post 15 to slide to run through on the U-shaped plate 14, the lateral wall that L shape pole 1 was run through to the upper end of gag lever post 15 offsets with dwang 3, the fixed fender shoulder 16 that is provided with on gag lever post 15, and keep off shoulder 16 and be located U-shaped plate 14 inboard, the fixed sloping block 17 that is provided with of lower extreme of gag lever post 15, and the inclined plane of sloping block 17 offsets with branch 20, the fixed thrust spring 18 that is provided with in upper end that keeps off shoulder 16, and the upper end and the L shape pole 1 fixed connection of thrust spring 18.

In long-term use, the non-newtonian fluid 7 may spill or fail, and the device will fail, and the possibility of rotation of the yarn around the coil 4 will remain when the yarn is not under load, and therefore a limit mechanism is designed to prevent the rotation of the rotating rod 3.

When the slide bar 10 is reset under the action of the reset spring 13, the yarn on the winding coil 4 is pulled out, after the slide bar 10 moves a distance, the support rod 20 can prop against the inclined plane of the inclined block 17 to push the inclined block 17 upwards, so that the upper end of the limiting rod 15 upwards props against the rotating rod 3, the rotating rod 3 can be stopped rotating quickly due to large friction force, the rotation of the winding coil 4 can be prevented, the buffer mechanism can stop pulling the winding coil 4 at the moment, and the yarn is prevented from being loosened and knotted or broken.
