fig. 2 is a left side view schematic diagram of the present invention.

Description of the figures the symbols:

1. a guide wire wheel body; 2. a transverse shredding tank; 3. a guide wire wheel axle hole; 4. and a guide wire wheel bearing.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, so that those skilled in the art can implement the present invention.

Example (b):

as shown in fig. 1-2, the utility model discloses install on equipment support shaft, drive through the silk bundle, it is equipped with seal wire wheel body 1, and seal wire wheel body 1 terminal surface center is equipped with seal wire wheel shaft hole 3, and the built-in seal wire wheel bearing 4 that is equipped with in seal wire wheel shaft hole 3 realizes the rotation in a circumferential direction. The V-shaped groove is arranged along the circumferential direction of the yarn guide wheel body 1 and serves as a working surface, the bottom of the V-shaped groove is straight, two transverse yarn cutting grooves 2 perpendicular to the V-shaped groove are symmetrically formed in the working surface of the bottom of the V-shaped groove, and yarns wound on the working surface of the yarn guide wheel are processed, so that the working surface of the yarn guide wheel is prevented from being scratched when a bush-hook or a blade is used for processing wound yarns at other places outside the groove. A transverse filament cutting groove 2 is formed in the 180-degree direction of the circumference of the filament guiding wheel respectively, so that the problem of dynamic and static balance of the filament guiding wheel is solved, the number of filament cutting points is also ensured, chamfering treatment is carried out along the periphery of the transverse filament cutting groove 2, and filament damage is prevented.

The guide wire wheel body 1 is made of aluminum alloy material, and the working surface of the guide wire wheel body is treated by a hard anodic oxidation treatment method, so that the corrosion resistance, the wear resistance, the heat resistance and the insulativity of the aluminum alloy working surface can be improved, and the working surface has certain surface hardness. The hardness of the godet wheel body 1 is more than or equal to 650HV, the surface smoothness range is Ra1.2-Ra1.6, and the adhesion of tows on the working surface of the godet wheel is reduced by pear treatment on the working surface.

When the carbon filaments which are skimmed off are wound on the working surface of the guide wire wheel body 1, the more the carbon filaments are wound, the quality of a tow product is influenced, an operator can align with the blades with proper specifications on the working surface of the guide wire wheel body 1 successively and leave the transverse filament cutting groove 2 of the tow just after the carbon filaments are cut off from the groove to the groove quickly, after the two grooves are cut off successively, the blades and the transverse filament cutting groove 2 of the guide wire wheel are separated quickly, then the cut carbon filaments are removed from the working surface of the guide wire wheel body 1 by hands, the quality of the carbon filaments on the guide wire wheel body 1 is not influenced when the carbon filaments run to the next process, and the running period, the full-axis rate and the product appearance quality of the tow are ensured.
