Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber production equipment, specifically a glass fiber tension self-balancing winding device. Background Technology

[0002] In the production of fiberglass, the winding process is one of the most crucial steps. During the winding process, the fiberglass needs to maintain a stable tension to ensure the quality of the wound fiberglass roll and avoid problems such as looseness, wrinkles, or uneven tension that could lead to fiberglass breakage.

[0003] Most existing fiberglass winding devices use a fixed tension control method, which makes it difficult to adjust in real time according to the actual tension changes of the fiberglass during the winding process. Mechanical tensioners have a narrow adjustment range, pneumatic / hydraulic systems have complex structures, and electronic closed-loop control requires frequent calibration and is not suitable for the high temperature and high humidity environment of fiberglass production lines.

[0004] To address the problems existing in the above-mentioned technologies, a fiberglass tension self-balancing winding device is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a glass fiber tension self-balancing winding device, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass tension self-balancing winding device, comprising: a frame, a winding shaft, a yarn guide, and a tension self-balancing mechanism;

[0007] The tension self-balancing mechanism consists of a floating tension roller group, a lever counterweight system, and an elastic damping module.

[0008] When the fiberglass tension increases, the guide roller will rise to achieve balanced fiberglass tension; when the fiberglass tension decreases, the guide roller will sink to achieve adaptive relaxation compensation.

[0009] As a preferred embodiment of the present invention, the floating tension roller group includes at least one yarn guide roller.

[0010] As a preferred technical solution of this utility model, the lever counterweight system consists of a pair of levers, with the fulcrum of the levers located on the frame. The short arm end is connected to the end of the yarn guide roller via a linear bearing, and the long arm end is provided with a mounting rod. The lever ratio ranges from 1:2.5 to 1:4.

[0011] As a preferred embodiment of this invention, a weight is suspended on the configuration rod, and the counterweight is set according to the yarn specifications.

[0012] As a preferred technical solution of this utility model, the elastic damping module is composed of a pneumatic damper integrated and installed at the end of the long arm. The damping coefficient is adjustable, and the resonance caused by yarn vibration can be suppressed by the pneumatic damper.

[0013] As a preferred technical solution of this utility model, the surface of the yarn guide roller is covered with a polyurethane wear-resistant layer with a thickness of ≥3mm.

[0014] As a preferred embodiment of this utility model, the yarn guide is located 300±50mm upstream of the yarn guide roller, and the center line of the ceramic eye of the yarn guide is 80-100mm lower than the center line of the floating roller.

[0015] As a preferred technical solution of this utility model, the inner wall of the ceramic eye of the yarn guide is provided with a composite ceramic curved surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By sensing changes in yarn tension in real time through a floating tension roller group, the changes are amplified by a lever counterweight system and driven to reverse balance by a counterweight block. Combined with an elastic damping module, high-frequency vibration is eliminated. The entire process is conducted without the involvement of electronic sensors, which solves the problems of high yarn breakage rate and difficult equipment maintenance in glass fiber winding and significantly improves the consistency of roll material quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3A fiberglass tension self-balancing winding device includes: a frame 1, a winding shaft 2, a yarn guide 3, and a tension self-balancing mechanism;

[0024] The tension self-balancing mechanism consists of a floating tension roller group, a lever counterweight system, and an elastic damping module.

[0025] When the fiberglass tension increases, the guide roller 5 will rise upwards to achieve balanced fiberglass tension. When the fiberglass tension decreases, the guide roller 5 will sink downwards to achieve adaptive relaxation compensation.

[0026] Specifically, the floating tension roller assembly includes at least one yarn guide roller 5.

[0027] Specifically, the lever counterweight system consists of a pair of levers 4, with the fulcrum of the levers 4 located on the frame 1. The short arm end is connected to the end of the yarn guide roller 5 via a linear bearing, and the long arm end is equipped with a mounting rod 6. The lever ratio ranges from 1:2.5 to 1:4.

[0028] Specifically, weights 7 are suspended on the configuration rod 6, and the counterweight is set according to the yarn specifications.

[0029] Specifically, the elastic damping module consists of a pneumatic damper 8 integrated and installed at the end of the long arm. The damping coefficient is adjustable, and the pneumatic damper 8 can suppress resonance caused by yarn vibration.

[0030] Specifically, the surface of the yarn guide roller 5 is coated with a polyurethane wear-resistant layer with a thickness of ≥3mm.

[0031] Specifically, the yarn guide 3 is located 300±50mm upstream of the yarn guide roller 5, and the center line of the ceramic eye of the yarn guide 3 is 80-100mm lower than the center line of the floating roller.

[0032] Specifically, the inner wall of the yarn guide's ceramic eye is provided with a composite ceramic curved surface 301.

[0033] Working principle: The counterweight 7 is set according to the yarn specifications. The knob of the air pressure damper 8 is adjusted until the yarn is free from vibration. During operation, the yarn passes under the guide roller 5, and the tension fluctuation is converted into lever displacement. The counterweight system automatically cancels the disturbance.
