Description

Technical Field

[0001] The present invention relates to the field of surface treatment of composite fibers, and more specifically, it relates to an integrated surface treatment device for composite fibers and a method for using the same. Background Art

[0002] Composite fibers are fibers composed of two or more different components, polymers with different structures, or other functional materials, and have a variety of excellent properties, and are widely used in the fields of textiles, medicine, aerospace, etc. In the production process of composite fibers, surface treatment is an important link. Through surface treatment, the hydrophilicity, wear resistance, antistatic property, etc. of the fibers can be improved to meet different usage requirements.

[0003] Traditional composite fiber surface treatment equipment usually consists of independent cleaning units, modification units, coating units, etc. The connection layout between each unit is chaotic, and the conveying path of the composite fibers is non-linear. This not only causes problems such as entanglement and bending of the fibers during the conveying process, but also makes it difficult to achieve coordinated work because each unit needs to be independently operated and controlled, resulting in low production efficiency and increased labor operation costs. In addition, due to the lack of effective tension control means, when the composite fibers are transmitted between different treatment units, the tension fluctuates greatly, and conditions such as slack or excessive tightness are likely to occur, resulting in problems such as incomplete cleaning, uneven spraying of modifiers, and poor coating adhesion effect, seriously affecting the quality stability and consistency of the composite fiber surface treatment, and it is difficult to meet the requirements of modern industrial production for high-quality composite fibers.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an integrated surface treatment device for composite fibers and a method for using the same. Summary of the Invention

[0015] The method of using the composite fiber integrated surface treatment device comprises the following steps: Step 1: Push the feeding mechanism, receiving mechanism, cleaning unit, modification unit and coating unit to move, so that the sliding sleeves at their bottoms move along the slide rod. After adjusting the positions of each mechanism / unit, lock the linear rollers around the bottom to fix the positions of each mechanism / unit on the slide rod; Step 2: Hold the handle, fix the inner column by the connecting rod and the rotating rod C so that it cannot rotate, start the motor B to drive the outer column to rotate, stagger the through groove A on the outer column and the locking block of the inner column, at this time the locking block is squeezed into the outer column, align the inner peripheral surface groove of the composite fiber winding drum with the positioning protrusion of the outer column, push it axially until the composite fiber winding drum is completely fitted, at this time the through groove A of the outer column is aligned with the through groove B of the composite fiber winding drum, keep the inner column immobile, rotate the outer column to align the locking block with the through groove A, the spring pushes the locking block out of the through groove A and the through groove B, clamps the composite fiber winding drum, completes the installation, installs the composite fiber winding drum with wound composite fibers on the feeding mechanism, installs an empty composite fiber winding drum on the receiving mechanism, connects one end of the composite fiber installed on the composite fiber winding drum on the feeding mechanism with the composite fiber winding drum on the receiving mechanism, so that the composite fiber is transported between the two mechanisms; Step 3: Unwind the composite fiber winding reel of the feeding mechanism.

If a new roll needs to be replaced, repeat Step 2.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating multiple processing units with unified control, the present invention forms a linear processing path of "feeding - cleaning - modification - coating - winding", and at the same time forms a dynamic balance system of "transportation - processing - tension control". It not only solves the technical pain points of the traditional equipment layout being chaotic, poor coordination, and unstable tension, but also constructs a fully controllable system from raw material input to finished product output, significantly improving the quality stability and production efficiency of composite fiber surface treatment, meeting the stringent requirements for high-performance fibers in the high-end manufacturing field, so as to solve the problem of chaotic connection layout between units in the background technology, the non-linear composite fiber conveying path, and the lack of a proposed continuous tension control means; 2. The present invention uses a tension sensor to monitor the stress state of the fiber in real time: when the feeding speed of the feeding mechanism fluctuates and causes the fiber to become slack, it is immediately and rapidly adjusted through two tensioning devices at the inlet and outlet. Relying on their linkage mechanism, the traction force is synchronously increased at a very fast speed. The inlet tensioning device applies a pulling force from the source to prevent the fiber from continuing to slack and accumulate, and the outlet tensioning device cooperates to tighten at the rear end of the unit to ensure that the fiber in the unit always maintains a constant tension; 3. The present invention provides a structure of an installation roller and a composite fiber winding reel that is convenient for disassembly and assembly, which can effectively improve the replacement efficiency of the composite fiber winding reel, thereby facilitating the improvement of the efficiency of composite fiber surface treatment and processing; 4. The feeding mechanism, material collecting mechanism, cleaning unit, modification unit, and coating unit of the present invention are sleeved on the sliding rod through the sliding sleeves at the bottom, and can slide on the sliding rod, which is convenient for adjusting the positions of each mechanism and unit. At the same time, it can also play a guiding role to a certain extent to ensure that they are on the same straight line. The linear rollers with locking functions installed around the bottom of the cleaning unit, modification unit, and coating unit can, on the one hand, assist each unit in moving on the sliding rod, and on the other hand, when the positions of each unit are determined, the linear rollers can be locked to fix the positions of each unit and prevent them from moving randomly, and the operation is relatively convenient.

[0019] Embodiment 1 As Figure 1 , Figure 4 and Figure 5 shown, the present invention provides an integrated surface treatment device for composite fibers, including a feeding mechanism 1 and a winding mechanism 2 for feeding and winding the composite fibers. Between the transportation of the feeding mechanism 1 and the winding mechanism 2, the composite fibers sequentially pass through a cleaning unit 4 (including drying), a modification unit 5, and a coating unit 6. The feeding mechanism 1, the winding mechanism 2, and each unit are kept in a straight line. The cleaning unit 4 is used for cleaning the composite fibers, the modification unit 5 is used for surface modification treatment of the composite fibers, and the coating unit 6 is used for coating treatment of the composite fibers. The work of the feeding mechanism 1, the winding mechanism 2, the cleaning unit 4, the modification unit 5, and the coating unit 6 is controlled by a unified control device; Tensioning devices 7 that are linked front and back are installed at the inlet and outlet parts of the cleaning unit 4, the modification unit 5, and the coating unit 6, so that the composite fibers maintain a constant tension between each processing unit, ensuring the stability of the processing process.

[0020] The feeding mechanism 1 and the material collecting mechanism 2, as the starting and ending points of fiber transmission, connect the cleaning unit 4, the modification unit 5, and the coating unit 6 in series through a straight-line layout, forming a linear processing path of "feeding - cleaning - modification - coating - material collecting" (integrating multiple processing units). Compared with the non-linear complex path of traditional equipment, this layout enables the composite fiber to maintain a straight movement trajectory under the action of gravity and traction force, eliminating the spatial conditions for fiber entanglement and bending from the physical structure, ensuring a smooth and interference-free conveying process, laying a foundation for subsequent processing procedures. The control device, as the "nerve center" of the equipment, synchronously regulates parameters such as the feeding speed of the feeding mechanism 1, the winding tension of the material collecting mechanism 2, the spraying frequency of the cleaning unit 4, the reagent spraying amount of the modification unit 5, and the roller pressing pressure of the coating unit 6 through preset programs or real-time instructions. When the cleaning time of the cleaning unit 4 needs to be adjusted due to changes in the fiber impurity content, the control device will synchronously instruct the feeding mechanism 1 and the feeding mechanism 2 to reduce the conveying speed to ensure that the processing rhythm of the modification unit 5 and the coating unit 6 is completely matched with the cleaning process, avoiding the problem of processing disconnection caused by the independent operation of each unit of traditional equipment and achieving precise coordination of the entire process. The front and rear linkage tensioning devices 7 installed at the inlets and outlets of the cleaning, modification, and coating unit 6 real-time monitor the stress state of the fiber through tension sensors: when the feeding speed of the feeding mechanism 1 fluctuates and causes the fiber to slacken, it immediately adjusts quickly through the two tensioning devices 7 at the inlet and outlet (due to linkage, both of them tighten almost simultaneously, with a faster tightening speed). Relying on their linkage mechanism, it synchronously increases the traction force at an extremely fast speed. The inlet tensioning device 7 applies a pulling force from the source to prevent the fiber from continuing to slacken and accumulate, while the outlet tensioning device 7 cooperates to tighten at the rear end of the unit to ensure that the fiber inside the unit always maintains a constant tension, preventing problems such as unsmooth conveying and poor processing effects caused by slackening, greatly improving the timeliness and effectiveness of the equipment in responding to speed fluctuations, thereby avoiding affecting the surface treatment effect of the composite fiber.

[0021] During use, the fiber is first fed into the cleaning unit 4 at a constant speed by the feeding mechanism 1, and the surface oil and impurities are removed through high-pressure spraying or ultrasonic cleaning; the cleaned fiber is smoothly introduced into the modification unit 5 through the inlet tensioning device 7, and the surface activity is activated under the action of modification processes such as corona treatment and plasma spraying; the modified fiber enters the coating unit 6 while maintaining tension through the outlet tensioning device 7, and solution coating, melt coating, or vapor deposition is carried out according to process requirements, and finally the material collecting mechanism 2 completes the winding according to the set coil diameter. During the whole process, the control device automatically switches the processing parameters of each unit according to the fiber type (such as glass fiber, carbon fiber), and the tensioning device 7 real-time adapts to the tension requirements in different processing stages (such as the weight change caused by material adhesion during the coating process), forming a dynamic balance system of "conveying - processing - tension control".

[0022] In summary, by integrating multiple processing units with unified control, this device not only solves the technical pain points of traditional devices such as chaotic layout, poor coordination, and unstable tension, but also constructs a fully controllable system from raw material input to finished product output, significantly improving the quality stability and production efficiency of composite fiber surface treatment, and meeting the stringent requirements for high-performance fibers in the high-end manufacturing field.

[0023] Embodiment 2 As Figures 1 - 5 shown, this embodiment gives the specific structure of the tensioning device 7 in Embodiment 1, as well as the specific structure for maintaining the relative straightness of the feeding mechanism 1, the winding mechanism 2, the cleaning unit 4, the modification unit 5, and the coating unit 6.

[0024] The following is the specific structure of the tensioning device 7: The tensioning device 7 includes four bearing seats 701 fixed on both sides of the surfaces of the cleaning unit 4, the modification unit 5, and the coating unit 6. Bearings A702 are installed inside the bearing seats 701. Rotating rods A703 are fixedly connected to the inner ring parts of the bearings A702. A lead screw 704 is installed between the upper and lower rotating rods A703. A rod sleeve 706 is installed on the outer side wall of the lead screw 704. Guide rails 707 for the slider 708 to slide are also fixedly connected to both sides of the surfaces of the cleaning unit 4, the modification unit 5, and the coating unit 6. The side ends of the slider 708 are respectively connected to the rod sleeve 706 through connecting plates A709. The other ends of the rod sleeve 706 and the connecting plate A709 are connected to the tensioning roller 705 through connectors 710. Tension sensors are installed on the tensioning roller 705 at the inlet of each unit. The rotating rod A703 at the bottom of one of the lead screws 704 is driven by a motor A711 installed on each unit. A transmission mechanism 8 is installed between the rotating rods A703 at the top of the lead screw 704 to drive the rotation of the other lead screw 704. The transmission mechanism 8 includes a gear A801 fixed to the top end of one of the rotating rods A703, and a pulley A805 fixed to the other rotating rod A703. The upper parts of the surfaces of the cleaning unit 4, the modification unit 5, and the coating unit 6 are respectively connected to bearings B803 through connecting plates B802. A rotating rod B804 is fixedly connected to the inner ring part of the bearing B803. A pulley B806 is fixedly connected to the bottom end of the rotating rod B804. The pulley A805 and the pulley B806 are driven by a belt. A gear B807 meshing with the gear A801 is fixedly connected to the bottom end of the pulley B806, so that the two lead screws 704 rotate in opposite directions.

[0025] It should be noted that the composite fiber passes under the tensioning roller 705 at the inlet of each unit, and this tensioning roller 705 is tensioned by lifting. The composite fiber passes under the tensioning roller 705 at the outlet of the unit, and this tensioning roller 705 is tensioned by pressing down.

[0026] When the composite fiber enters below the tension roller 705 at the inlet part of each unit, if the feeding speed of the feeding mechanism 1 fluctuates and causes the fiber to slacken, the tension sensor on the inlet tension roller 705 detects the tension change and transmits the signal to the control device. The control device drives the motor A711 to drive one of the lead screws 704 to rotate through the lever A703 connected to its transmission end. The lever A703 at the upper and lower ends of the lead screw 704 rotates along the inner ring part of the bearing A702, and its inner ring rotates along the outer ring of the bearing A702. The lever A703 is rotationally supported by the bearing A702. At the same time, the rotation of the lever A703 also drives the rotation of the gear A801. Since the gear A801 meshes with the gear B807, it will drive the gear B807 to rotate in the opposite direction. When the gear B807 rotates, it will drive the rotation of the lever B804, and the lever B804 is rotationally supported by the bearing B803. At the same time, the gear B807 also drives the pulley B, and the pulley B drives the rotation of the pulley A805 through the belt. Finally, it drives the lever A703 and the lead screw 704 on the other side to rotate in the opposite direction. The bushings 706 on the two lead screws 704 also move in the opposite direction. At the same time, the bushings 706 on the two lead screws 704 drive the slider 708 to move through the connecting plate A709. The slider 708 moves linearly along the guide rail 707, so as to maintain the up and down linear movement of the bushing 706. The bushing 706 drives the inlet and outlet tension rollers 705 to act synchronously through the connecting piece 710 - the inlet tension roller 705 is lifted and the outlet tension roller 705 is pressed down, applying tension to the fiber from the upper and lower directions respectively, increasing the fiber wrap angle and contact length, thereby increasing the tension force; if the fiber tension is too large, the motor A711 rotates in reverse, the inlet tension roller 705 descends and the outlet tension roller 705 ascends, reducing the tension force. In the whole process, the inlet and outlet tension device 7 is linked through the control device to realize the rapid and accurate adjustment of the fiber tension, so that the fiber maintains a constant tension in the whole processing unit.

[0027] The following is the specific structure for maintaining the relative straightness of the feeding mechanism 1, the winding mechanism 2, the cleaning unit 4, the modification unit 5 and the coating unit 6; the bottom ends of the feeding mechanism 1, the winding mechanism 2, the cleaning unit 4, the modification unit 5 and the coating unit 6 are all fixedly connected with sliding sleeves 9, and they are slidably connected to the sliding rod 10 through the sliding sleeves 9. Linear rollers 11 with locking functions are installed around the bottom ends of the cleaning unit 4, the modification unit 5 and the coating unit 6. Counterweight seats 12 are fixedly connected to both ends of the sliding rod 10.

[0028] The feeding mechanism 1, the material collecting mechanism 2, the cleaning unit 4, the modification unit 5, and the coating unit 6 are sleeved on the sliding rod 10 through the sliding sleeves 9 at the bottom, and can slide on the sliding rod 10, which is convenient for adjusting the positions of each mechanism and unit. At the same time, it can also play a guiding role to a certain extent to ensure that they are on the same straight line. The linear rollers 11 with locking functions installed around the bottom of the cleaning unit 4, the modification unit 5, and the coating unit 6 can, on the one hand, assist each unit in moving on the sliding rod 10, and on the other hand, when the positions of each unit are determined, the positions of each unit can be fixed by locking the linear rollers 11 to prevent them from moving randomly, and the operation is relatively convenient. The counterweight seats 12 fixedly connected to both ends of the sliding rod 10 play a role of balance and stability, increasing the stability of the entire equipment, reducing the shaking caused by the offset of the equipment's center of gravity or external forces, thereby maintaining the linear layout between the feeding mechanism 1, the material collecting mechanism 2, and each unit, ensuring the linearity of the composite fiber during transportation, and avoiding problems such as winding and bending.

[0029] Example 3 As Figure 1 、 Figures 4 - 9 shown, this example gives the specific structures of the feeding mechanism 1 and the material collecting mechanism 2: Both the feeding mechanism 1 and the material collecting mechanism 2 include a support platform 13 and a support plate A 14 located at the top of the support platform 13. An installation roller 16 driven by a motor B 15 is installed on the support plate A 14. The installation roller 16 is used to install the composite fiber winding reel 3. When in use, the composite fiber winding reel 3 is installed on the installation roller 16. In this way, when the motor B 15 drives the installation roller 16 to rotate, it will also drive the rotation of the composite fiber winding reel 3 to realize the winding or unwinding of the fiber (the speed and rotation direction of the motor B are precisely regulated by the control device to match the processing speed and tension requirements of the composite fiber). In order to improve the efficiency of the surface treatment and processing of the composite fiber, this embodiment provides a structure for the installation roller 16 and the composite fiber winding reel 3 that is convenient for disassembly and assembly: The installation roller 16 includes an outer column 1601 and an inner column 1602 located inside the outer column 1601, and the two rotate relative to each other. A plurality of positioning protrusions 1603 arranged in a circumferential array are provided on the outer peripheral surface of the outer column 1601. A plurality of grooves 301 arranged in a circumferential array and matching the positioning protrusions 1603 are opened on the inner peripheral surface of the composite fiber winding reel 3. Locking blocks 1604 are installed at both ends of the inner column 1602. A through groove A 1605 for the locking block 1604 to pass through is opened on the outer column 1601, and a through groove B 302 for the locking block 1604 to pass through is opened on the outer side wall of the composite fiber winding reel 3. When the through groove A 1605 is not aligned with the locking block 1604, the locking block 1604 is extruded inside the outer column 1601. When the through groove A 1605 is aligned with the locking block 1604, the locking block 1604 extends out from the through groove A 1605.

[0030] During use, first hold the inner column 1602 to prevent it from rotating. At the same time, drive the outer column 1601 of the mounting roller 16 to rotate by the motor B15 (the transmission shaft of the motor B15 is connected to the mounting roller 16), so as to rotate the locking block 1604 to a position where it is not aligned with the through groove A1605, and squeeze the locking block 1604 inside the outer column 1601. Then, the composite fiber winding reel 3 can be sleeved on the outer column 1601, and at the same time, the groove 301 is also inserted on the positioning protrusion 1603, so as to axially position the composite fiber winding reel 3 relative to the outer column 1601 (the composite fiber winding reel 3 cannot rotate along the outer column 1601). When the composite fiber winding reel 3 is completely inserted on the outer column 1601, the through groove A1605 and the through groove B302 are exactly aligned. Then, hold the inner column 1602 again to prevent it from rotating, and at the same time drive the rotation of the outer column 1601 by the motor B15, so that the locking block 1604 is aligned with the through groove A1605. Without obstruction, the locking block 1604 pops out from the through groove A1605 and also passes through the through groove B302, and the composite fiber winding reel 3 can be fixed on the outer column 1601. Similarly, hold the inner column 1602 again to prevent it from rotating, and at the same time drive the rotation of the outer column 1601 by the motor B15, so as to squeeze the locking block 1604 in the outer column 1601, and the fixation of the composite fiber winding reel 3 and the outer column 1601 can be released. Pull the composite fiber winding reel 3 off the outer column 1601 to complete the disassembly of the composite fiber winding reel 3. The disassembly and assembly are very convenient, which can effectively improve the replacement efficiency of the composite fiber winding reel 3.

[0031] Furthermore, four support plates B1606 are fixedly connected to both ends of the inner column 1602. The surfaces of the support plates B1606 are all connected to the four locking blocks 1604 through springs 1607. The two sides of the locking block 1604 are provided with bevel edges A16041, and the two sides of the through groove A1605 are provided with bevel edges B16051 adapted to the bevel edges A16041. An expansion rod 1608 is also installed between the locking block 1604 and the support plate B1606. Both sides inside the outer column 1601 are fixedly connected with bearings C1609. A rotating rod C1610 is fixedly connected to the inner ring part of the bearing C1609. The inner column 1602 is fixed between the two rotating rods C1610. One end of one of the rotating rods C1610 is fixedly connected with a connecting rod 1611. A circular through groove 1612 for the connecting rod 1611 to pass through is provided on the side end of the outer column 1601. A handle 1613 is fixedly connected to the head of the connecting rod 1611.

[0032] That is, by holding the connecting rod 1611 with the handle 1613, the connecting rod 1611 restricts the inner column 1602 through the rotating rod C1610 to prevent it from rotating. When the outer column 1601 is driven by the motor B15 to rotate, the outer column 1601 drives the rotation of the outer ring of the bearing C1609 (the outer ring of the bearing C1609 is fixed to the outer column 1601). The outer ring of the bearing C1609 rotates relative to the inner ring of the bearing C1609, so that the outer column 1601 rotates relative to the inner column 1602 fixed in the inner ring of the bearing C1609 through the rotating rod C1610. When the locking block 1604 is aligned with the through groove A1605, there is no longer any obstruction to the locking block 1604 and the spring 1607. The spring 1607 will support the locking block 1604, so that it penetrates out of the through groove A1605. At this time, when the outer column 1601 is rotated again, the hypotenuse B16051 of the through groove A1605 on the outer column 1601 will squeeze the hypotenuse A16041 on the locking block 1604 (the inclination angles of the inclined plate A16041 and the hypotenuse B1605 match each other), so as to press the locking block 1604 into the outer column 1601. When the locking block 1604 moves back and forth, the telescopic rod 1608 between the locking block 1604 and the support plate B1606 will also expand and contract accordingly, so that the locking block 1604 can move back and forth in a straight line, preventing the locking block 1604 from getting out of position and at the same time preventing the spring 1607 from being damaged by oblique pulling.

[0033] The present invention also provides a method for using the integrated surface treatment equipment for the above composite fiber: Step 1: Push the feeding mechanism 1, the material receiving mechanism 2, the cleaning unit 4, the modification unit 5 and the coating unit 6 to move, so that the sliding sleeves 9 at their bottoms move along the sliding rods 10. After adjusting the positions of the respective mechanisms / units, lock the linear rollers 11 around the bottoms of them to fix the positions of the respective mechanisms / units on the sliding rods 10; Step 2: Hold the handle 1613, fix the inner column 1602 through the connecting rod 1611 and the rotating rod C1610 to prevent it from rotating, start the motor B15 to drive the outer column 1601 to rotate, stagger the through groove A1605 on the outer column 1601 with the locking block 1604 of the inner column 1602, at this time the locking block 1604 is squeezed into the outer column 1601, align the inner circumferential groove 301 of the composite fiber winding drum 3 with the positioning protrusion 1603 of the outer column 1601, and push it axially until the composite fiber winding drum 3 is completely fitted, at this time the through groove A1605 of the outer column 1601 is aligned with the through groove B302 of the composite fiber winding drum 3, keep the inner column 1602 stationary, and rotate the outer Column 1601 (drives motor B15 through control device to drive outer column 1601 to rotate slightly), so that locking block 1604 is aligned with through slot A1605, spring 1607 pushes locking block 1604 to pass through through slot A1605 and through slot B302, clamps composite fiber take-up drum 3, and completes installation, installs composite fiber take-up drum 3 with wound composite fiber on feeding mechanism 1, installs empty composite fiber take-up drum 3 on receiving mechanism 2 (to receive composite fiber), connects one end of composite fiber on composite fiber take-up drum 3 installed on feeding mechanism 1 with composite fiber take-up drum 3 on receiving mechanism 2, so that composite fiber can be transported between the two mechanisms; Step 3: The composite fiber reel 3 of the feeding mechanism 1 unwinds, and the composite fiber enters the cleaning unit 4, where impurities are removed and the fiber is dried by high-pressure spraying or ultrasonic cleaning; after cleaning and drying, the fiber passes through the modification unit 5, where surface activity is activated by corona treatment or plasma spraying; the modified fiber is sent to the coating unit 6, where solution coating or melt coating is performed according to process requirements; Step 4: If the feeding speed fluctuates and causes the composite fiber to relax, the tension sensor of the unit inlet tensioning roller 705 will provide real-time feedback signals, and the control device will drive the motor A711 to synchronously adjust the inlet and outlet tensioning rollers 705 (lift up at the inlet and press down at the outlet) to increase the tensioning force; if the tension is too large, adjust it in the opposite direction to ensure that the fiber tension is constant. The treated fiber enters the receiving mechanism 2 through the outlet tensioning roller 705 of the coating unit 6 (press down to tension), and is wound up by the composite fiber winding drum 3 according to the set winding diameter; Step 5: After the surface treatment process is completed, the coating unit 6, the modification unit 5, and the cleaning unit 4 are shut down in sequence through the control device. After the fiber is completely rolled up, the motor B15 of the feeding mechanism 1 and the receiving mechanism 2 is turned off, and the handle 1613 is held to fix the inner column 1602. The motor B15 is started to rotate the outer column 1601 so that the bevel B16051 of the through groove A1605 squeezes the bevel A16041 of the locking block 1604, and the locking block 1604 is pressed into the outer column 1601 until the locking block 1604 is completely disengaged from the through groove B302, and the composite fiber winding drum 3 is pulled out axially to complete the disassembly. If a new roll needs to be replaced, repeat step 2.

[0034] An integrated surface treatment device for composite fibers and its usage method according to the present invention have the following advantages: By integrating multiple processing units and unified control, a linear processing path of "feeding - cleaning - modification - coating - winding" is formed, and at the same time, a dynamic balance system of "conveying - processing - tension control" is formed. It not only solves the technical pain points of traditional equipment such as chaotic layout, poor coordination, and unstable tension, but also constructs a fully controllable system from raw material input to finished product output, significantly improving the quality stability and production efficiency of composite fiber surface treatment, and meeting the strict requirements for high-performance fibers in the high-end manufacturing field; The stress state of the fiber is monitored in real time by a tension sensor: when the feeding speed of the feeding mechanism 1 fluctuates and causes the fiber to slack, it is immediately and quickly adjusted by two tensioning devices 7 at the inlet and outlet. With their linkage mechanism, the traction force is synchronously increased at a very fast speed. The inlet tensioning device 7 applies a pulling force from the source to prevent the fiber from continuing to slack and pile up, and the outlet tensioning device 7 cooperates to tighten at the rear end of the unit to ensure that the fiber in the unit always maintains a constant tension; A structure of the mounting roller 16 and the composite fiber winding drum 3 that is convenient for disassembly and assembly is provided, which can effectively improve the replacement efficiency of the composite fiber winding drum 3, thereby facilitating the improvement of the efficiency of composite fiber surface treatment processing; The feeding mechanism 1, the winding mechanism 2, the cleaning unit 4, the modification unit 5, and the coating unit 6 are sleeved on the sliding rod 10 through the sliding sleeves 9 at the bottom and can slide on the sliding rod 10, facilitating the position adjustment of each mechanism and unit. At the same time, it can also play a guiding role to a certain extent to ensure that they are on the same straight line. The linear rollers 11 with locking functions installed around the bottom of the cleaning unit 4, the modification unit 5, and the coating unit 6 can, on the one hand, assist each unit in moving on the sliding rod 10, and on the other hand, when the positions of each unit are determined, the positions of each unit can be fixed by locking the linear rollers 11 to prevent them from moving randomly, and the operation is relatively convenient.

Step 2: Hold the handle (1613), fix the inner column (1602) through the connecting rod (1611) and the rotating rod C (1610) so that it cannot rotate. Start the motor B (15) to drive the outer column (1601) to rotate, and stagger the through slot A (1605) on the outer column (1601) from the locking block (1604) of the inner column (1602).

Align the inner circumferential groove (301) of the composite fiber winding reel (3) with the positioning protrusion (1603) of the outer column (1601), and axially push it until the composite fiber winding reel (3) is fully sleeved. At this time, the through slot A (1605) of the outer column (1601) is aligned with the through slot B (302) of the composite fiber winding reel (3). Keep the inner column (1602) stationary and rotate the outer column (1601) to align the locking block (1604) with the through slot A (1605).
