Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber wire collecting machines, in particular to a wire guiding device of a carbon fiber wire collecting machine. Background Art

[0002] Carbon fiber is an inorganic polymer fiber with a carbon content of more than 92%. Carbon fiber has high axial strength and modulus, no creep, good fatigue resistance, specific heat and conductivity between non-metal and metal, and small thermal expansion coefficient. The fiber is widely used in aerospace, high-speed rail transportation, sporting goods, chemical machinery, textile machinery and other fields. The carbon fiber wire collecting machine is the last step in the manufacture of carbon fiber. It is used to collect and wind up the carbon fiber to facilitate subsequent processing. The carbon fiber entering the wire collecting machine needs to pass through the wire guide device to guide the carbon fiber into the wire collecting machine.

[0003] The existing wire guide devices have a fixed spacing and cannot thread carbon fiber filaments of different widths. It is troublesome to replace different wire guide devices. After long-term use, the rollers are worn and gaps are directly generated in the rollers, affecting the stability of threading. The surface of the rollers of the existing wire guide devices is relatively smooth. In actual use, there may be a risk of carbon fiber fibers being offset and falling off, affecting the quality of the wire collection machine. When the rollers of the existing wire guide devices are damaged, it is troublesome to replace them. Tools are required to remove the screws, and the entire roller needs to be replaced at one time, which is relatively wasteful. Therefore, in view of the above problems, a wire guide device for a carbon fiber wire collection machine is proposed. Utility Model Content

Under the action of the spring, the rotating shaft and the roller can be adjusted up and down according to the thickness of the carbon fiber fiber, and are compatible with carbon fiber fibers of different sizes, thereby solving the problem that the existing wire guide devices have a fixed spacing and cannot be used to thread carbon fiber wires of different widths, and it is troublesome to replace different wire guide devices. After long-term use, the rollers are worn, and gaps are directly generated in the rollers, which affects the stability of threading.
