Problems solved by technology

[0004] However, in the prior art, when collecting the carbon fiber tow, it is necessary to accurately fix the end of the carbon fiber tow on the collecting device at the initial stage, and the carbon fiber material has a strong brittleness, especially the position of the end of the fiber, and the carbon fiber The diameter of the tow is small. The above two factors will make it difficult to ensure the integrity of the carbon fiber tow and the accuracy of the connection with the collection equipment when fixing the carbon fiber tow, which seriously reduces the efficiency of the carbon fiber tow collection work.

Embodiment 1

[0036] Example 1, such as Figure 1-8 As shown, the present invention provides a carbon fiber tow collection device for carbon fiber production, comprising a tow collection tray 1, a tow stopper 3, a drive fixing ring 4, a rotating motor 5 and a fixed base 6, the tow The outside of the bottom of the collecting tray 1 is installed movably with the top of the drive fixing ring 4, and the bottom axis of the drive fixing ring 4 is plugged with a rotating shaft 50, and the outside of the bottom of the rotating shaft 50 is movable with the top axis of the rotating motor 5. The installation is used for the rotating motor 5 to drive the fixed ring 4 through the rotating shaft 50, thereby driving the tow collecting disc 1 to rotate at a uniform speed, so that the carbon fiber tow can be wound to the outside of the tow collecting disc 1, and the bottom outside of the rotating motor 5 It is fixedly installed with the top axis of the fixed base 6, and is used to limit the bottom of the ro...

Embodiment 2

[0042] Embodiment 2, on the basis of Embodiment 1, two magnetic clamps 7 are installed symmetrically on the outside of the tow deflection groove 11, which is used to limit the deflection of the carbon fiber tow that is wound on the outside of the tow collection tray 1 at the initial stage. Angle, the two magnetic clamps 7 all include a shell 701, one end of the shell 701 is fixedly installed on one side of the tow deflection groove 11, and the other end of the shell 701 is fixedly installed with a limit block 704, the shell The inner side of the part 701 is provided with a movable groove 702, and the inner side of the movable groove 702 is movably installed with a magnet 703, and the driving and fixing ring part 4 includes an outer ring part 401 and a drive block 404, and the top of the outer ring part 401 is uniformly fixed with four Connecting clamps 402, the tops of the four connecting clamps 402 are clamped with the bottom of the tow collection tray 1, and the inner side of...

Abstract

The invention provides a carbon fiber tow collection device for carbon fiber production, which relates to the technical field of carbon fiber production and manufacturing equipment, including a tow collection plate, a tow limiter, a driving and fixing ring, a rotating motor and a fixed base. The axis of the tow collection disc is provided with an axis hole, and one side of the axis hole is provided with a tow deflection groove. The tow collection plate is the winding matrix of the carbon fiber tow, which facilitates the collection of the carbon fiber tow. material operation. The present invention solves the problem that when collecting the carbon fiber tow, the end of the carbon fiber tow needs to be accurately fixed on the collecting device at the initial stage, and the carbon fiber material is very brittle, especially the position of the end of the fiber, and the carbon fiber tow The diameter of the tow is small, and the above two factors will make it difficult to ensure the integrity of the carbon fiber tow and the accuracy of the connection with the collection equipment when the carbon fiber tow is fixed, which seriously reduces the problem of carbon fiber tow collection work efficiency.

Description

technical field [0001] The invention relates to the technical field of carbon fiber production and manufacturing equipment, in particular to a carbon fiber tow collection equipment used for carbon fiber production. Background technique [0002] Carbon fiber is a fibrous carbon material with a carbon content of more than 90%. It is prepared by high-temperature solid-state reaction processes such as pre-oxidation, carbonization, and graphitization of organic fibers—polyacrylonitrile fibers, viscose fibers, and pitch fibers. It is made of graphite microcrystals with preferred orientation, so it has high strength and elastic modulus. When the production of carbon fiber materials is completed, it is often in the form of filaments, and it needs to be stored and transported after it is collected . [0003] In the prior art, such as Chinese Patent No.: CN112873912A "A Tow Collection Equipment for Carbon Fiber Production", which includes a tow collection equipment body, an outer fra...
