Description

Technical Field

[0001] This utility model relates to the field of fiber processing equipment, and more specifically, to a stretching and shaping mechanism for radiation-resistant rare earth composite fibers. Background Technology

[0002] Due to their unique properties, radiation-shielding rare earth composite fibers have broad application prospects in many fields such as electronics, medical, and aerospace. In the production process of radiation-shielding rare earth composite fibers, stretching and setting is one of the key steps, directly affecting the fiber's performance and quality. A search revealed an existing patent (publication number: CN220114166U) disclosing a radiation-resistant elastic micro-wrinkled fabric, belonging to the field of elastic fabric technology. The fabric includes a base layer and a radiation-resistant layer. The base layer is woven from base warp and weft yarns in a plain weave, and both the base warp and weft yarns are composite fiber yarns. The surface of the base layer has a micro-wrinkled structure. The radiation-resistant layer is located on the surface of the base layer and is woven using silver ion fibers as warp and nylon fibers as weft. This invention, through the combined action of the base layer and the radiation-resistant layer, utilizes composite fiber yarns (both warp and weft) made of elastic cotton fibers, effectively ensuring the fabric's elasticity. The presence of the radiation-resistant layer gives the fabric excellent radiation protection performance.

[0003] The existing radiation-resistant rare earth composite fiber matrix is ​​prone to thermal shrinkage after stretching, which squeezes the rare earth particles inside. Some particles are easy to fall off from the fiber surface, resulting in local agglomeration of rare earth particles inside the fiber. At the same time, the patent documents cited above do not propose any solutions to solve the above problems. Therefore, a stretching and shaping mechanism for radiation-resistant rare earth composite fibers is proposed to address the above problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0019] As attached Figures 1 to 4 The stretching and shaping mechanism of the radiation-proof rare earth composite fiber shown includes a base 1, a shaping box 13 is provided on the upper end of the base 1, a temperature and humidity sensor 15 is provided on one side inside the shaping box 13, a humidifier 16 is symmetrically arranged at both ends inside the temperature and humidity sensor 15, atomizing nozzles 17 are evenly spaced on opposite sides of the humidifier 16, and an electric heating tube 18 is provided on one side of each humidifier 16.

[0020] Specifically, by setting atomizing nozzles 17, water vapor is evenly sprayed into the shaping box 13, so that the humidity inside the box can be quickly raised to the preset range. The uniform spacing design of the atomizing nozzles 17 can ensure that the water vapor is evenly distributed in the box, avoiding local humidity that is too high or too low. Example

[0021] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the base 1 has symmetrical grooves 8 at both ends. A micro motor 9 is installed on one side of the groove 8, and a lead screw 10 is connected to the other side of the micro motor 9. Furthermore, by installing the micro motor 9, the slider 11 is driven to move horizontally along the groove 8, thereby changing the position of the active roller 5 connected to the slider 11, so as to achieve precise adjustment of the distance between the active roller 5 and the driven roller 6.

[0022] In a preferred embodiment, the lead screw 10 is externally threaded with a slider 11, which is fitted inside the slide groove 8, and a column 2 is fixedly provided on the upper end of the slider 11. Furthermore, by providing the slide groove 8, the slide groove 8 constrains the movement direction of the slider 11, preventing the slider 11 from deviating during movement, ensuring that the active roller 5 moves only in the horizontal direction, and avoiding uneven fiber stretching force caused by roller body deviation.

[0023] In a preferred embodiment, a connecting seat 3 is fixedly installed at the upper end of the column 2, and a drive motor 4 is installed inside the connecting seat 3. A drive roller 5 is connected to one side of the drive motor 4. Furthermore, by installing the drive roller 5, the drive roller 5 provides stable power for fiber conveying by using friction with the fiber, ensuring that the fiber continuously enters the stretching and shaping stage at a preset speed.

[0024] In a preferred embodiment, a driven roller 6 is provided on one side of the active roller 5, and a base 1 is connected to the bottom of the driven roller 6 through a connecting column. A limiting block 12 is fixedly provided on one side of the slide groove 8. Furthermore, by providing the limiting block 12, the limiting block 12 can limit the maximum travel of the slider 11, preventing the active roller 5 and the driven roller 6 from being too far apart, which would cause the fibers to detach, or too close apart, which would cause the rollers to collide and be damaged.

[0025] In a preferred embodiment, a tension sensor 7 is provided on one side of the driven roller 6, and a pressure sensor 20 is provided on the other side of the tension sensor 7. Furthermore, by providing the tension sensor 7, the actual tension value during the fiber stretching process can be collected in real time and the data can be transmitted to the controller 19 to avoid fiber breakage and rare earth particle shedding due to excessive tension, or insufficient stretching due to insufficient tension.

[0026] In a preferred embodiment, guide rollers 14 are symmetrically arranged at both ends of the shaping box 13, and a controller 19 is fixedly arranged on one side of the column 2; furthermore, by providing guide rollers 14, the rotation characteristics of the guide rollers 14 can buffer the instantaneous tension change of the fiber when entering and leaving the shaping box 13, and prevent the fiber from shifting position during the shaping process due to sudden tension change.

[0027] The working process of this utility model is as follows: First, the radiation-resistant rare earth composite fiber raw material to be processed is pulled at one end, through the gap between the driven roller 6 and the driving roller 5, and then introduced into the shaping box 13 through the guide roller 14 on one side of the shaping box 13. The guide roller 14 reduces the frictional resistance during the fiber conveying process by rotating itself, while ensuring that the fiber always moves along the preset path, avoiding fiber deviation that would cause uneven stretching or shaping in the later stages. The pressure sensor 20 monitors the clamping force of the driving roller 5 and the driven roller 6 on the fiber in real time. If the clamping force does not reach the set threshold, the micro motor 9 in the slide groove 8 at both ends of the base 1 drives the lead screw 10 to rotate. The lead screw 10 is threadedly engaged with the slider 11, driving the slider 1 1. The slider 11 moves horizontally along the chute 8, thereby moving the column 2, connecting seat 3, and drive roller 5, which are fixedly connected to the slider 11, as a whole. This changes the distance between the drive roller 5 and the driven roller 6 until the pressure sensor 20 returns the value within a safe pressure range, ensuring that the fiber is stably clamped and not damaged. The tension sensor 7 on the driven roller 6 side collects the actual tension value of the fiber in real time and transmits the data to the controller 19, achieving precise control of the fiber stretching force and preventing rare earth particles from agglomerating or falling off due to uneven stretching. In addition, the limiting block 12 on the chute 8 side can limit the movement stroke of the slider 11, preventing the drive roller 5 and the driven roller 6 from moving together. Excessive or insufficient spacing can cause equipment malfunction or fiber damage. The stretched fibers enter the setting chamber 13 via guide roller 14. A temperature and humidity sensor 15 on one side of the setting chamber 13 monitors the temperature and humidity data in real time and transmits the data to the controller 19. When the temperature and humidity sensor 15 detects that the temperature inside the chamber is lower than a preset value, the controller 19 activates the electric heating element 18 on one side of the humidifier 16. The electric heating element 18 heats up, raising the temperature inside the setting chamber 13. Once the temperature reaches the preset range, the electric heating element 18 switches to a heat preservation mode to maintain a stable temperature. When the humidity inside the chamber is detected to be lower than a preset value, the controller 19 activates the humidifier... The humidifier 16 converts water into water vapor, which is then evenly sprayed into the setting chamber 13 through atomizing nozzles 17 with equal spacing on their opposite surfaces. This causes the humidity inside the chamber to rise rapidly to a preset range. The even spacing of the atomizing nozzles 17 ensures that the water vapor is evenly distributed inside the chamber, avoiding excessively high or low humidity in certain areas. This ensures that the setting chamber 13 is always in a temperature and humidity environment that meets the requirements for setting radiation-resistant rare earth composite fibers, promoting stable cross-linking of fiber molecular chains, reducing fiber thermal shrinkage, and preventing rare earth particles from being squeezed out. The fibers that have completed the setting process are discharged from the outlet end of the setting chamber 13, completing the entire stretching and setting process.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
