Description

Technical Field

[0001] The utility model relates to the technical field of adjustment devices, in particular to a tension adjustment device for processing composite fiber materials. Background Art

[0002] The tension adjustment device in fiber material processing is a key device used to ensure that fibers (such as yarns, filaments or fiber tapes) maintain stable tension during processing. This device is crucial to ensuring product quality because it can prevent problems such as fiber breakage due to excessive tension or fiber relaxation and knotting due to low tension.

[0003] After searching, the document of announcement number "CN221216523U" mentioned that "the utility model discloses a tension adjustment device for processing composite fiber materials, which relates to the field of adjustment devices, including a support frame, a support rod is arranged at the bottom of the support frame, a motor is fixed to the top of the support rod, a first rotating rod is fixed to the output end of the motor, the other end of the first rotating rod is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a tension roller. The utility model sets a tension roller, a winding roller, a motor, a first rotating rod, a connecting rod and a limit groove. When the composite fiber material body is wound up, the sensor on the tension roller senses the tension of the composite fiber material body on the tension roller. When the tension is too small or too large, the sensor transmits a signal to the controller, and the controller controls the motor to start, driving the connecting rod to move up and down in the limit groove to adjust the pressure on the composite fiber material body, thereby adjusting the composite fiber material body. The device is configured to adjust the tension of the composite fiber material body as evenly as possible by providing a tension roller, a winding roller, a motor, a first rotating rod, a connecting rod, a support rod, and a limit slot. When the composite fiber material body is wound, a sensor on the tension roller senses the tension of the composite fiber material body on the tension roller. When the tension is too low or too high, the sensor transmits a signal to the controller, which starts the motor, driving the first rotating rod to rotate, thereby driving the connecting rod to rotate. The connecting rod moves upward within the limit slot to reduce the pressure on the composite fiber material body, thereby reducing the tension, or moves downward within the limit slot to increase the pressure on the composite fiber material body, thereby increasing the tension, thereby adjusting the winding tension. However, the motor of the device generates vibrations during operation, and these vibrations are transmitted to the tension adjustment device, causing tension fluctuations and affecting the stability and quality of fiber material processing.

[0004] Therefore, we provide a tension adjustment device for processing composite fiber materials to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the setting of the working mechanism, when the motor generates vibration during operation, the vibration force is first transmitted to the connecting plate, and the connecting plate then transmits the force to the mounting frame. After being subjected to the force, the mounting frame squeezes the piston rod, and the sliding rod outside the piston rod moves relative to each other in the sliding groove to form a friction surface. Due to the contact pressure between the two friction surfaces, friction is generated between them. As the sliding rod moves, the friction force does work, converting the vibration energy into heat energy, thereby reducing the amplitude and duration of the vibration. In addition, the first spring further offsets the vibration force from the motor through its elastic deformation, plays a buffering role, and reduces the vibration transmitted to other structural components. At the same time, the second spring controls the rebound of the piston rod to avoid excessive rebound of the piston rod due to vibration, further reducing the vibration transmitted to the entire device, thereby continuously absorbing and dissipating vibration energy during the operation of the motor, ensuring that the entire tension adjustment device maintains smooth operation during operation.

[0016] 2. Through the setting of the working components, the motor provides power to the tension roller, and the tension roller is used to apply and adjust the tension of the fiber material to ensure the stability of the tension during the processing, thereby ensuring the uniformity of the material and the stability of product quality.
