Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber winding equipment, and in particular to a carbon fiber yarn frame. Background Technology

[0002] In carbon fiber winding, the yarn register is used to store and supply carbon fiber yarn, and its structure and performance have a significant impact on winding quality and production efficiency. Existing carbon fiber winding yarn registers have some shortcomings. For example, the yarn tension is prone to instability during unwinding, leading to uneven distribution of the wound carbon fiber and affecting product quality. Furthermore, the traditional yarn register design is not flexible enough to accommodate different specifications and quantities of yarn rolls, and changing yarn rolls is cumbersome, time-consuming, and labor-intensive, reducing production efficiency. In addition, during high-speed winding, the friction between the yarn and the yarn register components is significant, easily causing yarn wear and affecting the performance of the carbon fiber. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as unstable yarn tension during unwinding, resulting in uneven distribution of wound carbon fibers and affecting product quality; the inflexible structure of traditional yarn frames, which cannot adapt to different specifications and quantities of yarn packages, and the cumbersome, time-consuming, and labor-intensive operation of changing yarn packages, thus reducing production efficiency. Furthermore, the high friction between the yarn and the yarn frame components during high-speed winding easily causes yarn wear, affecting the performance of the carbon fibers. Therefore, this invention proposes a carbon fiber yarn frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A carbon fiber yarn frame includes a carbon fiber skeleton, with multiple unwinding mechanisms installed on one side of the inner side of the carbon fiber skeleton, multiple horizontal yarn guide rollers arranged inside the carbon fiber skeleton, multiple vertical yarn guide mechanisms arranged on one side of the carbon fiber skeleton, and multiple tension detection mechanisms arranged inside the carbon fiber skeleton, with the tension detection mechanisms located between the horizontal yarn guide rollers and the vertical yarn guide mechanisms. The number of unwinding mechanisms, horizontal yarn guide rollers, vertical yarn guide mechanisms, and tension detection mechanisms is the same.

[0006] In one possible design, the unwinding mechanism includes a servo motor, a bearing housing, a motor adjustment mounting plate, and an air shaft. The motor adjustment mounting plate is installed inside the carbon fiber skeleton. The bearing housing and the servo motor are fixedly connected to the top of the motor adjustment mounting plate. The air shaft is located inside the bearing housing, and the output shaft of the servo motor is fixedly connected to one end of the air shaft.

[0007] In one possible design, the bearing housing is provided with an elastic retaining ring and a bore spring retaining ring inside, both of which are used in conjunction with the bearing housing and the air shaft. The bearing housing is also provided with a bearing and a spacer inside, which are used in conjunction with the air shaft.

[0008] In one possible design, the bearing housing is further provided with an adjustment device, which includes a screw plug that is threadedly fitted to the inner hole of the bearing housing to press against the bearing, an adjustment shim that is threadedly connected to the adjustment screw plug to restrict the rotation of the screw plug, and a bearing cover that is provided on the opening of the inner hole of the bearing housing to seal it.

[0009] In one possible design, the yarn vertical guide mechanism is provided with a bidirectional adjustment mounting plate and double-sided vertical guide rollers.

[0010] In one possible design, the tension detection mechanism includes a hollow tube guide shaft to prevent falling, double-sided horizontal guide rollers, and a tension detection sensor.

[0011] In one possible design, the carbon fiber skeleton is equipped with a yarn-separating guide roller and a tension calibration roller inside, and a control box is embedded on one side of the carbon fiber skeleton.

[0012] In this application, the yarn frame is assembled as follows: First, the frame components are assembled according to the design requirements, and the components are securely connected using bolts or other connectors. Then, according to the specifications and quantity of the carbon fiber yarn to be wound, the yarn mounting shaft is mounted on the adjustable motor mounting base, and the mounting base is mounted on the frame. By adjusting the position and angle of the mounting base on the frame, the yarn mounting shaft is positioned appropriately.

[0013] Installing the yarn package: Install the yarn package on the yarn mounting shaft and use the air shaft structure to fix the yarn package, ensuring that the yarn package is firmly installed and can rotate freely.

[0014] Tension Adjustment: Based on the carbon fiber winding process requirements, the servo motor torque is adjusted via a controller to set the appropriate yarn tension. During the winding process, a tension detection device monitors the carbon fiber tension in real time and feeds it back to the servo system. The servo system adjusts the motor torque based on the real-time tension value to maintain a constant carbon fiber tension.

[0015] Winding operation: Initiate carbon fiber winding. The yarn passes through guide rollers with a low-friction coating and winds along a predetermined path. During the winding process, continuously monitor the yarn tension and winding condition to ensure winding quality.

[0016] Beneficial effects: By setting an adjustable tension regulating device, precise control of the tension of each yarn can be achieved, ensuring uniform distribution of the wound fibers and improving product quality.

[0017] The modular and adjustable installation structure allows the yarn rack to adapt to different specifications and quantities of yarn packages, making yarn package replacement easy and improving production efficiency.

[0018] The friction-reducing components effectively reduce friction between the yarn and the yarn frame components, reduce yarn wear, ensure the performance of carbon fiber, and extend the service life of the yarn frame. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The tension detection mechanisms 5 are located between the yarn horizontal guide rollers 3 and the yarn vertical guide mechanisms 4. The number of unwinding mechanisms 2, yarn horizontal guide rollers 3, yarn vertical guide mechanisms 4 and tension detection mechanisms 5 are the same.

[0026] The unwinding mechanism 2 includes a servo motor 9, a bearing housing 10, a motor adjustment mounting plate 11, and an air shaft 12. The motor adjustment mounting plate 11 is installed inside the carbon fiber frame 1. The bearing housing 10 and the servo motor 9 are fixedly connected to the top of the motor adjustment mounting plate 11. The air shaft 12 is located inside the bearing housing 10, and the output shaft of the servo motor 9 is fixedly connected to one end of the air shaft 12. The flexible installation structure features a modular design, with its frame composed of multiple detachable components. The yarn mounting shaft is mounted on the frame via an adjustable motor mounting base. The mounting base can move horizontally and vertically on the frame and can rotate at a certain angle to accommodate yarn packages of different specifications and placement requirements. In addition, the yarn frame is equipped with a device for quick yarn package replacement, such as an air shaft 12 mounting structure. Simply inflating or deflating the air shaft allows for quick loading and unloading of the yarn package. The bearing housing 10 contains an elastic retaining ring 13 and a hole spring retaining ring 15, both of which cooperate with the bearing housing 10 and the air shaft 12. The bearing housing 10 also contains a bearing 16 and a spacer 17, which cooperate with the air shaft 12. Tension adjustment mechanism: The yarn frame includes multiple yarn mounting shafts, each equipped with a servo motor 9. A tension detection device is installed in each yarn path. This tension detection device measures the real-time tension of the yarn and feeds it back to the servo system. By changing the torque of the servo motor 9, the real-time tension of the yarn is adjusted, thereby achieving precise control of the yarn tension.

[0027] The bearing housing 10 is also provided with an adjustment device 14. The adjustment device 14 includes a screw plug that is threadedly fitted to the inner hole of the bearing housing 10 and presses against the bearing 16, an adjustment shim that is threadedly connected to the adjustment screw plug and restricts the rotation of the screw plug, and a cover for the bearing 16 that is provided on the opening of the inner hole of the bearing housing 10.

[0028] This application can be used in the field of carbon fiber winding equipment, or in other fields applicable to this application.

[0029] Example 2

[0030] refer to Figure 1-3An improvement upon Example 1: A carbon fiber yarn frame, applied to the field of carbon fiber winding equipment, includes a bidirectional adjustment mounting plate 18 and double-sided vertical guide rollers 19 on the yarn vertical guide mechanism 4. The tension detection mechanism 5 includes an anti-drop hollow tube guide shaft 20, double-sided horizontal guide rollers 21, and a tension detection sensor 22. The carbon fiber frame 1 internally houses a yarn-separating guide roller 6 and a tension calibration roller 7. A control box 8 is embedded on one side of the carbon fiber frame 1. Friction-reducing components: Low-friction coefficient coatings, such as polytetrafluoroethylene coatings, are applied to the contact points between the yarn and the yarn frame, such as the surface of the yarn mounting shaft and the yarn guide components. Simultaneously, various horizontal and vertical rolling guide rollers are installed along the yarn guide path. These guide rollers are made of lightweight, wear-resistant materials, such as aluminum alloy coated with polyurethane rubber, to reduce friction between the yarn and the guide components and decrease yarn wear.

[0031] However, as is well known to those skilled in the art, the working principle and wiring method of the tension detection sensor 22, the control box 8 and the servo motor 9 are commonplace. The adjustment device 14 is consistent with the bearing limit adjustment device proposed in CN104165191A. They are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.
