Description

Technical Field

[0001] This invention belongs to the field of differentiated fiber production technology, specifically relating to a segmented temperature-controllable differentiated fiber directional modification and impregnation device and its usage method. Background Technology

[0002] In fiber modification, solution modification is a key process for improving fiber performance. Its core requirement is to achieve differentiated solution treatment at different stages based on the fiber's modification needs. Existing solution modification devices mostly employ a single-chamber structure, which cannot achieve segmented temperature control or independent use of different solution solutions. This results in the fiber not achieving a gradient modification effect during solution modification, leading to poor solution uniformity. Simultaneously, existing devices have poor solution circulation, easily causing uneven solution concentrations, affecting fiber modification quality and reducing the stability and consistency of solution modification. Therefore, we propose a segmented, temperature-controlled, differentiated fiber-oriented modification solution modification device and its application method. Summary of the Invention

[0003] The purpose of this invention is to provide a segmented temperature-controllable differential fiber directional modification impregnation device and its usage method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a segmented temperature-controllable differentiated fiber orientation modification and impregnation device, comprising:

[0005] Support frame;

[0006] The immersion chamber has at least two chambers, which are arranged sequentially on the support frame, and each immersion chamber contains a different immersion solution.

[0007] A solution circulation assembly is provided at the bottom of each of the immersion chambers for circulating and fully mixing the immersion solution within the immersion chambers;

[0008] A heating temperature control component is provided on the outside of each of the impregnation chambers to achieve independent temperature control within each impregnation chamber.

[0009] Fiber guiding components are provided at both ends of the support frame to guide the fibers through the inlet and outlet of the device.

[0010] The impregnation guide component is provided in each of the impregnation chambers. It works in conjunction with the fiber guide component to guide the fiber through each impregnation chamber.

[0011] Preferably, the bottom of the support frame is provided with adjustable mounting feet.

[0012] Preferably, a heat insulation plate fixedly connected to the support frame is provided between adjacent immersion chambers. The size of the heat insulation plate is adapted to the end face size of the immersion chamber to block temperature crosstalk between adjacent immersion chambers.

[0013] Preferably, the solution circulation assembly includes a circulation pump, a solution circulation pipe, and a solution addition port;

[0014] The circulation pump is located on the bottom outside of the immersion chamber. The input and output ends of the circulation pump are connected to the inside of the immersion chamber through the solution circulation pipe to form a closed-loop circulation circuit for the immersion solution. The solution addition port is connected to the solution circulation pipe for adding the immersion solution.

[0015] Preferably, the heating temperature control assembly includes a heating insulation jacket and a temperature controller;

[0016] The heating and insulation jacket is wrapped in a ring around the outer wall of the immersion chamber. The heating and insulation jacket is tightly fitted to the outer wall of the immersion chamber. The temperature controller is mounted on the support frame and is electrically connected to the heating and insulation jacket.

[0017] Preferably, the heating temperature control assembly further includes a temperature sensor, which is disposed at the bottom of the immersion chamber and has its detection end extending to the bottom of the immersion chamber and in direct contact with the immersion solution inside the immersion chamber. This sensor is used to collect solution temperature data in real time and transmit it to the temperature controller. The temperature controller adjusts the heating power of the heating and insulation jacket based on the temperature signal fed back by the temperature sensor, thereby achieving independent temperature control in each of the immersion chambers.

[0018] Preferably, the fiber guiding assembly includes fiber guiding rollers, which are disposed at both ends of the support frame. The axis of the fiber guiding rollers is perpendicular to the fiber travel direction, and is used to guide the fiber and preliminarily adjust the tension to ensure that the fiber enters the impregnation chamber in a preset direction.

[0019] Preferably, the immersion guide assembly includes immersion guide rollers, and three immersion guide rollers are provided. The three immersion guide rollers are distributed in an inverted triangle in the immersion chamber, and the bottom of the lowest immersion guide roller is lower than the liquid level of the immersion solution in the immersion chamber, so that the fiber travels along the bottom of the immersion chamber after passing around the immersion guide roller, ensuring that the fiber is fully immersed in the immersion solution.

[0020] Preferably, the upper side of the impregnation chamber has a groove extending through both ends, and the upper part of the uppermost impregnation guide roller is higher than the groove, so that the fiber can move smoothly through the groove.

[0021] A method for using a segmented, temperature-controlled differential fiber orientation modification and impregnation device includes the following steps:

[0022] A. Device Debugging and Parameter Presetting: Adjust the adjustable mounting feet at the bottom of the support frame to keep the device horizontal and stable, and inject a preset type of impregnation solution into each impregnation chamber. Replenish the impregnation solution to the preset level through the solution addition port of the solution circulation component. Preset the target temperature of the impregnation solution in each impregnation chamber through the temperature controller of the heating temperature control component. The preset target temperature of each impregnation chamber can be adjusted independently. The temperature difference of the impregnation solution in two adjacent impregnation chambers is 5-20℃ to form a temperature gradient suitable for fiber segment modification. At the same time, set the traveling speed of the fiber to be modified. The traveling speed adjustment range is 0.1-0.5m / min to ensure that the temperature and type of impregnation solution in different impregnation chambers are suitable for the fiber segment modification requirements.

[0023] B. Fiber Orientation: One end of the differentiated fiber to be modified is passed through the fiber guide roller of the fiber guide assembly at one end of the support frame, and then sequentially through the grooves at both ends on the upper side of each impregnation chamber. The fiber passes around the impregnation guide rollers arranged in an inverted triangle in each impregnation chamber, so that the fiber travels along the bottom of the impregnation chamber after passing around the impregnation guide rollers, and the fiber is completely immersed in the impregnation solution. During fiber insertion, the tension of the fiber guide roller on the fiber is adjusted to keep the fiber tension at 5-20N. Finally, the other end of the fiber is passed through the fiber guide roller at the other end of the support frame to complete the fiber orientation insertion.

[0024] C. Heating Temperature Control: The heating temperature control component is activated, and the heating insulation jacket heats the corresponding immersion chamber. The temperature sensor at the bottom of the immersion chamber collects the immersion solution temperature data in real time and transmits it to the temperature controller. The temperature sensor collects the immersion solution temperature 1-5 times / minute. Based on the feedback temperature signal, the temperature controller independently adjusts the heating power of the heating insulation jacket corresponding to each immersion chamber to stabilize the immersion solution temperature in each immersion chamber at the preset target temperature, thereby achieving segmented differentiated temperature control.

[0025] D. Circulation of impregnation solution: Start the circulation pump of the solution circulation component at the bottom of each impregnation chamber. The operating speed of the circulation pump is 500-1500 r / min, and the circulation flow rate of the impregnation solution in the impregnation chamber is 0.3-1 m³ / h. This ensures that the impregnation solution is mixed evenly and does not cause severe disturbance that could damage the fibers. The circulation pump drives the impregnation solution in the impregnation chamber to form a closed loop circulation through the solution circulation pipe, so that the impregnation solution is fully mixed.

[0026] E. Uniform Fiber Travel and Solution Modification: Adjust the rotation speed of the fiber guide rollers at both ends of the support frame to drive the differentiated fibers through at a preset travel speed. By adjusting the rotation speed of the fiber guide rollers, the solution time of the fibers in each solution chamber is precisely controlled to ensure that the fibers are fully solution modified. The fibers pass through each solution chamber in sequence and complete the segmented directional solution modification in solution solutions of different types and temperatures until the fibers are output from the fiber guide roller at the other end of the support frame.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Significant effect of segmented temperature control: By setting independent heating and temperature control components on the outside of each impregnation chamber, combined with temperature sensors and heat insulation plates, independent and precise temperature control of each impregnation chamber can be achieved, which can form a temperature gradient suitable for fiber modification, avoid insufficient modification or fiber damage caused by a single temperature, and greatly improve the uniformity and stability of fiber modification.

[0029] 2. Good uniformity of impregnation: The solution circulation component realizes the closed-loop circulation of the impregnation solution, ensuring uniform solution concentration. At the same time, the impregnation guiding component guides the fiber to be fully immersed in the solution, prolonging the contact time. Combined with the orientation effect of the fiber guiding component, it avoids fiber deviation and entanglement, further improving the uniformity and sufficiency of impregnation modification.

[0030] 3. Convenient operation and high stability: Adjustable mounting feet facilitate device leveling, solution addition port facilitates solution replenishment, fiber threading and parameter adjustment are simple and easy to perform; all components are firmly connected, and the operation is stable, enabling continuous fiber impregnation modification and improving production efficiency;

[0031] 4. High adaptability: Multiple impregnation chambers can be configured with different types of impregnation solutions, and parameters such as temperature, travel speed, and tension can be flexibly adjusted, which can adapt to the segmented modification needs of different types of differentiated fibers and has a wide range of applications.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-7 The present invention provides a segmented temperature-controllable differential fiber directional modification impregnation apparatus, comprising:

[0042] The support frame 1 is equipped with adjustable mounting feet 101 at the bottom, which facilitates the adjustment of the level and installation height of the support frame 1, ensuring that the device can maintain horizontal stability in different installation environments, avoiding problems such as leakage of impregnation solution and fiber deviation caused by device tilting, and improving the stability of device operation.

[0043] At least two impregnation chambers 2 are provided and sequentially arranged on the support frame 1, and each impregnation chamber 2 contains a different impregnation solution; the arrangement of multiple impregnation chambers 2 realizes segmented differentiated impregnation modification of fibers. The different impregnation solutions in different impregnation chambers 2 can be configured according to the fiber modification requirements to meet the impregnation requirements of different stages of fibers and avoid the problem of poor modification effect caused by a single impregnation solution.

[0044] A heat insulation plate 102 fixedly connected to the support frame 1 is provided between adjacent impregnation chambers 2. The size of the heat insulation plate 102 is adapted to the end face size of the impregnation chamber 2. It is used to block temperature crosstalk between adjacent impregnation chambers 2, effectively isolate the temperature of adjacent impregnation chambers 2, avoid heat transfer between impregnation chambers with different temperatures, and ensure that the temperature in each impregnation chamber 2 can be stably maintained at the preset value, so as to achieve true segmented independent temperature control and ensure the effect of segmented fiber modification.

[0045] Solution circulation component 3: Each impregnation chamber 2 is equipped with a solution circulation component 3 at the bottom for circulating and fully mixing the impregnation solution in the impregnation chamber 2. Its function is to ensure that the concentration of the impregnation solution in the impregnation chamber 2 is uniform, avoid uneven fiber impregnation modification caused by excessively high or low local concentrations, and promote full contact between the impregnation solution and the fiber to improve the impregnation modification efficiency.

[0046] The solution circulation assembly 3 includes a circulation pump 301, a solution circulation pipe 302, and a solution addition port 303. The circulation pump 301 is located on the bottom outside of the immersion chamber 2. The input and output ends of the circulation pump 301 are connected to the inside of the immersion chamber 2 through the solution circulation pipe 302, forming a closed-loop circulation circuit for the immersion solution. The solution addition port 303 is connected to the solution circulation pipe 302 for adding the immersion solution. The circulation pump 301 provides power for the solution circulation. The closed-loop circulation of the immersion solution is achieved through the solution circulation pipe 302, which ensures that the immersion solution is fully mixed and the concentration is uniform. The solution addition port 303 allows for easy replenishment of the immersion solution at any time, maintaining a stable solution level and concentration in the immersion chamber 2 without disassembling the device, thus improving operational convenience.

[0047] Heating temperature control component 4: Each impregnation chamber 2 is equipped with a heating temperature control component 4 on its outer side. This component is used to achieve independent temperature control in each impregnation chamber 2. It can precisely adjust the temperature in each impregnation chamber 2 according to the temperature requirements of fiber segment modification, forming a gradient temperature environment to adapt to the modification requirements of different stages of fiber and avoid insufficient fiber modification or excessive damage caused by a single temperature.

[0048] The heating and temperature control assembly 4 includes a heating and insulation jacket 401 and a temperature controller. The heating and insulation jacket 401 is annularly wrapped around the outer wall of the immersion chamber 2, and the heating and insulation jacket 401 is tightly fitted to the outer wall of the immersion chamber 2. The temperature controller is mounted on the support frame 1, and the heating and insulation jacket 401 is electrically connected to the temperature controller. The heating and insulation jacket 401 can uniformly heat the immersion chamber 2, while also providing insulation to reduce heat loss and energy consumption. The temperature controller is used to control the heating state of the heating and insulation jacket 401, thereby achieving precise adjustment of the temperature inside the immersion chamber 2.

[0049] The heating temperature control assembly 4 also includes a temperature sensor 402. The temperature sensor 402 is located at the bottom of the impregnation chamber 2, and the detection end of the temperature sensor 402 extends to the bottom of the impregnation chamber 2 and is in direct contact with the impregnation solution in the impregnation chamber 2. It is used to collect solution temperature data in real time and transmit it to the temperature controller. The temperature controller adjusts the heating power of the heating and insulation jacket 401 based on the temperature signal fed back by the temperature sensor 402, so as to realize independent temperature control in each impregnation chamber 2. The temperature sensor 402 can collect the temperature data of the impregnation solution in real time and accurately, providing a basis for the adjustment of the temperature controller. The temperature controller can adjust the heating power in real time according to the temperature feedback, ensuring that the temperature in each impregnation chamber 2 is stable at the preset target temperature. The temperature control accuracy is high, and temperature fluctuations are avoided from affecting the fiber modification effect.

[0050] Fiber guiding component 5 is provided at both ends of the support frame 1 to guide the fiber through the device at the inlet and outlet ends; its function is to guide the fiber and make preliminary tension adjustment to ensure that the fiber enters the impregnation chamber 2 smoothly along the preset direction, and to avoid the fiber from running off course or getting tangled when entering and exiting the device, thus laying the foundation for subsequent directional impregnation.

[0051] The fiber guiding assembly 5 includes a fiber guiding roller 501, which is disposed at both ends of the support frame 1. The axis of the fiber guiding roller 501 is perpendicular to the fiber travel direction. It is used to guide the fiber and preliminarily adjust the tension to ensure that the fiber enters the impregnation chamber 2 in a preset direction. The fiber guiding roller 501 guides the fiber to travel smoothly by rotating. At the same time, the fiber tension can be preliminarily adjusted by adjusting the rotation speed and pressure of the roller to avoid the fiber from breaking due to excessive tension or running off course or getting tangled due to insufficient tension. This ensures that the fiber can smoothly enter the impregnation chamber 2 in a preset direction.

[0052] The immersion guide component 6 is provided in each immersion chamber 2. It works in conjunction with the fiber guide component 5 to guide the fiber through each immersion chamber 2. It can guide the fiber to travel along a preset path in the immersion chamber 2, ensuring that the fiber is fully immersed in the immersion solution, prolonging the contact time between the fiber and the immersion solution, and improving the uniformity and sufficiency of immersion modification.

[0053] The immersion guide assembly 6 includes immersion guide rollers 601, and three immersion guide rollers 601 are provided. The three immersion guide rollers 601 are arranged in an inverted triangle in the immersion chamber 2, and the bottom of the lowest immersion guide roller 601 is lower than the liquid surface of the immersion solution in the immersion chamber 2. This allows the fiber to pass around the immersion guide roller 601 and then travel along the bottom of the immersion chamber 2, ensuring that the fiber is fully immersed in the immersion solution. The inverted triangle arrangement of the immersion guide rollers 601 can guide the fiber to form a stable travel path, allowing the fiber to pass around the roller and then travel along the bottom of the immersion chamber 2, ensuring that the fiber is fully immersed in the immersion solution, avoiding the fiber floating on the solution surface and causing insufficient immersion, while also extending the contact time between the fiber and the solution and improving the uniformity of immersion modification.

[0054] The upper side of the impregnation chamber 2 has a groove 201 that runs through both ends. The upper part of the uppermost impregnation guide roller 601 is higher than the groove 201, which allows the fiber to move smoothly through. The groove 201 provides a passage for the fiber, ensuring that the fiber can smoothly enter the next impregnation chamber 2 from one impregnation chamber 2. At the same time, the uppermost impregnation guide roller 601 is higher than the groove 201, which can limit and guide the fiber, preventing the fiber from deviating from the preset path during the passage, and ensuring that the fiber completes the segmented impregnation smoothly and stably.

[0055] The method of using the segmented temperature-controllable differentiated fiber orientation modification and impregnation device provided by the present invention includes the following steps:

[0056] A. Device Debugging and Parameter Presetting: Adjust the adjustable mounting feet 101 at the bottom of the support frame 1 to keep the device horizontal and stable, and avoid tilting the device from affecting operation. Inject a preset type of impregnation solution into each impregnation chamber 2. Replenish the impregnation solution to the preset level through the solution addition port 303 of the solution circulation component 3 to ensure that the fiber can be fully impregnated. Preset the target temperature of the impregnation solution in each impregnation chamber 2 through the temperature controller of the heating temperature control component 4. The preset target temperature of each impregnation chamber 2 can be adjusted independently. The temperature difference of the impregnation solution in two adjacent impregnation chambers 2 is 5-20℃ to form a temperature gradient suitable for fiber segment modification. At the same time, set the traveling speed of the fiber to be modified. The traveling speed adjustment range is 0.1-0.5m / min to ensure that the temperature and type of impregnation solution in different impregnation chambers 2 are suitable for the fiber segment modification requirements.

[0057] B. Fiber Orientation: One end of the differentiated fiber to be modified is passed through the fiber guide roller 501 of the fiber guide assembly 5 at one end of the support frame 1, and then through the grooves 201 at both ends on the upper side of each impregnation chamber 2. The fiber passes around the impregnation guide rollers 601 arranged in an inverted triangle in each impregnation chamber 2, so that the fiber passes around the impregnation guide rollers 601 and then adheres to the bottom of the impregnation chamber 2. The fiber is completely immersed in the impregnation solution. During fiber insertion, the tension of the fiber guide roller 501 on the fiber is adjusted to keep the fiber tension at 5-20N. Finally, the other end of the fiber is passed through the fiber guide roller 501 at the other end of the support frame 1 to complete the fiber orientation insertion.

[0058] C. Heating Temperature Control: The heating temperature control component 4 is activated, and the heating insulation jacket 401 heats the corresponding immersion chamber 2. The temperature sensor 402 set at the bottom of the immersion chamber 2 collects the immersion solution temperature data in real time and transmits it to the temperature controller. The temperature sensor 402 collects the immersion solution temperature at a frequency of 1-5 times / minute. Based on the feedback temperature signal, the temperature controller independently adjusts the heating power of the heating insulation jacket 401 corresponding to each immersion chamber 2, so that the immersion solution temperature in each immersion chamber 2 is stabilized at the preset target temperature, thereby realizing segmented differentiated temperature control.

[0059] D. Circulation of impregnation solution: Start the circulation pump 301 of the solution circulation component 3 at the bottom of each impregnation chamber 2. The operating speed of the circulation pump 301 is 500-1500 r / min, and the circulation flow rate of the impregnation solution in the impregnation chamber 2 is 0.3-1 m³ / h. This ensures that the impregnation solution is mixed evenly and does not cause severe disturbance that could damage the fibers. The circulation pump 301 drives the impregnation solution in the impregnation chamber 2 to form a closed loop circulation through the solution circulation pipe 302, so that the impregnation solution is fully mixed.

[0060] E. Uniform Fiber Travel and Solution Modification: Adjust the rotation speed of the fiber guide rollers 501 at both ends of the support frame 1 to drive the differentiated fibers to travel uniformly at a preset speed. By adjusting the rotation speed of the fiber guide rollers 501, the solution time of the fibers in each solution chamber 2 is precisely controlled to ensure that the fibers are fully solution modified. The fibers pass through each solution chamber 2 in sequence and complete the segmented directional solution modification in solution solutions of different types and temperatures until the fibers are output from the fiber guide rollers 501 at the other end of the support frame 1.

[0061] The beneficial effects of this invention are as follows:

[0062] 1. Significant effect of segmented temperature control: By setting an independent heating temperature control component 4 on the outside of each impregnation chamber 2, together with the temperature sensor 402 and the heat insulation plate 102, the temperature in each impregnation chamber 2 can be independently and accurately controlled, which can form a temperature gradient suitable for fiber modification, avoid insufficient modification or fiber damage caused by a single temperature, and greatly improve the uniformity and stability of fiber modification.

[0063] 2. Good uniformity of impregnation: The solution circulation component 3 realizes the closed-loop circulation of the impregnation solution, ensuring uniform solution concentration. At the same time, the impregnation guide component 6 guides the fiber to be fully immersed in the solution, prolonging the contact time. Combined with the orientation effect of the fiber guide component 5, it avoids fiber deviation and entanglement, further improving the uniformity and sufficiency of impregnation modification.

[0064] 3. Convenient operation and high stability: The adjustable mounting feet 101 facilitate device leveling, the solution addition port 303 makes it easy to replenish the solution, and the fiber insertion and parameter adjustment are simple and easy to perform; all components are firmly connected and operate stably, enabling continuous fiber impregnation modification and improving production efficiency.

[0065] 4. High adaptability: Multiple impregnation chambers 2 can be configured with different types of impregnation solutions, and parameters such as temperature, travel speed, and tension can be flexibly adjusted, which can adapt to the segmented modification needs of different types of differentiated fibers and has a wide range of applications.

When inserting the fiber, adjust the tension of the fiber guide roller (501) on the fiber to keep the fiber tension at 5-20N. Finally, pass the other end of the fiber through the fiber guide roller (501) at the other end of the support frame (1) to complete the orientation insertion of the fiber. C. Heating temperature control: Start the heating temperature control component (4), and the heating insulation jacket (401) heats the corresponding immersion chamber (2). The temperature sensor (402) set at the bottom of the immersion chamber (2) collects the immersion solution temperature data in real time and transmits it to the temperature controller. The temperature sensor (402) collects the immersion solution temperature at a frequency of 1-5 times / minute. The temperature controller adjusts the heating power of the heating insulation jacket (401) corresponding to each immersion chamber (2) independently according to the feedback temperature signal, so that the immersion solution temperature in each immersion chamber (2) is stabilized at the preset target temperature, and segmented differentiated temperature control is realized. D. Circulation of impregnation solution: Start the circulation pump (301) of the solution circulation component (3) at the bottom of each impregnation chamber (2). The operating speed of the circulation pump (301) is 500-1500 r / min. The circulation flow rate of the impregnation solution in the impregnation chamber (2) is 0.3-1 m³ / h. This ensures that the impregnation solution is mixed evenly and does not cause severe disturbance that damages the fiber. The circulation pump (301) drives the impregnation solution in the impregnation chamber (2) to form a closed loop circulation through the solution circulation pipe (302) so that the impregnation solution is fully mixed. E. Uniform fiber movement and solution modification: Adjust the rotation speed of the fiber guide rollers (501) at both ends of the support frame (1) to drive the differentiated fibers to pass through at a preset speed. By adjusting the rotation speed of the fiber guide rollers (501), the solution time of the fibers in each solution chamber (2) is precisely controlled to ensure that the fibers are fully solution modified. The fibers pass through each solution chamber (2) in sequence and complete the segmented directional solution modification in different types and temperatures of solution until the fibers are output from the fiber guide rollers (501) at the other end of the support frame (1).
