Description

Technical Field

[0001] The utility model belongs to the field of carbon fiber chopped fibers and relates to a multi-station fiber withdrawal device for producing chopped carbon fibers. Background Art

[0002] As a kind of raw material, carbon fiber chopped fiber has excellent mechanical properties and chemical stability, and is widely used in various fields such as aerospace, automobiles, and sports equipment. The production of chopped fibers is to unwind the fibers wound on the shaft into a certain length and a certain number of fiber bundles, and then use the chopped machine to produce chopped fibers. In the conventional production of carbon fiber chopped fibers, the carbon fibers on the shaft are manually pulled and unfolded into fiber bundles, and the reciprocating pulling is carried out until the amount of the bundle is sufficient for the chopped machine to cut. However, manual unwinding has the following disadvantages: 1. The fiber is unevenly stressed, making the fiber extremely easy to break; 2. Manual unwinding requires two people to operate at the same time, one person pulling at one end and one person cutting at the other end, which is not efficient; 3. The number of fibers in each bundle is not fixed; 4. The unwinding speed is slow. Utility Model Content

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the utility model is to provide a multi-station wire withdrawal device for the production of short-cut carbon fibers, so as to solve the technical problems of uneven fiber force, low wire withdrawal efficiency and non-fixed number of fibers in each bundle during manual wire withdrawal.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a multi-station wire withdrawal device for the production of short-cut carbon fibers, comprising a wire guide hole plate and a wire winding disk through which the carbon fibers pass in sequence; the wire winding disk is connected to a driving fixing device;

[0006] The wire guide hole plate is evenly provided with a plurality of wire guide holes; the wire winding disc is provided with a plurality of wire winding grooves, and the positions of the wire winding grooves correspond to the positions of the wire guide holes;

[0007] A shearing opening is provided on the side of the wire winding disc.

[0008] In a specific implementation process, the wire winding disc is a coaxially arranged cage roller.

[0009] In a specific implementation process, the diameter of the winding drum is 1 to 2 m, and the winding drum can realize the withdrawal of 3 to 5 m of carbon fiber bundles.

[0010] In the specific implementation process, the wire guide hole plate is a ceramic wire guide hole plate; the wire winding reel is an aluminum alloy wire winding reel.

[0011] In a specific implementation process, the driving and fixing device includes a driving device and a fixing device; the driving device is arranged on the fixing device.

[0012] In a specific implementation process, the driving device is a motor, and the rotation speed of the motor matches the strength of the carbon fiber.

[0013] In a specific implementation, the fixing device includes a motor seat and a base;

[0014] The motor is arranged on a motor seat, and the motor seat is arranged on a base.

[0015] In a specific implementation process, the wire winding reel is connected to the motor, and the wire winding reel and the motor are arranged on a motor seat and a base.

[0016] In a specific implementation process, the plurality of wire guide hole arrays are arranged on a wire guide hole plate.

[0017] In a specific implementation process, the height of the wire guide hole is higher than the height of the wire winding reel.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model provides a multi-station wire withdrawal device for the production of short-cut carbon fibers. The wire guide holes evenly arranged on the wire guide hole plate ensure the uniform distribution of the carbon fibers during the wire withdrawal process, prevent the fibers from crossing or winding, facilitate the accurate positioning and smooth passage of the fibers, and reduce the resistance of the fibers during the wire withdrawal process. The rotation of the wire reel is achieved through a driving device, which provides a continuous and stable tension for the carbon fibers and avoids the problem of breakage caused by intermittent force. The wire reel grooves arranged on the wire reel correspond to the positions of the wire guide holes, ensuring that the fibers can be accurately and orderly rolled into the wire reel grooves, improving the wire withdrawal efficiency and the uniformity of the fibers. The shear cut design on the side facilitates the shearing of the fibers after the wire withdrawal is completed, which is convenient for subsequent processing or storage. The multi-station design is achieved by combining multiple wire guide holes and a wire reel, which increases the number of axes for each wire withdrawal, improves the wire withdrawal efficiency, and reduces the space occupied by the machine. The multi-station design allows the wire withdrawal process to be carried out simultaneously, further improving production efficiency.

[0020] Furthermore, the speed of the winding disc can be adjusted according to the fiber strength through the speed regulating motor, ensuring the stability and integrity of the fiber during the unwinding process. When the fiber strength is high, the speed of the winding disc can be increased, and vice versa. The flexible speed adjustment adapts to the unwinding requirements of fibers of different strengths and improves the applicability and operational flexibility of the equipment.
