Description

Technical Field

[0001] The utility model belongs to the field of carbon fiber production, and more specifically, relates to a simulation device for a carbon fiber oxidation furnace. Background Art

[0002] During the pre-oxidation stage of carbon fiber, wire breakage and wire bundle entanglement on the roller are likely to occur. Therefore, on-site personnel need to have a high emergency handling ability to ensure that sudden problems can be safely handled without stopping the production. This can ensure that the wire bundle can proceed smoothly during the oxidation stage without affecting the product output and quality.

[0003] On-site personnel can only practice wire connection and roller entanglement by cutting good wires during the oxidation stage. This will affect the output of carbon fiber and is prone to the risk of fire in the oxidation furnace, bringing extremely unstable hidden dangers to production.

[0004] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a simulation device for a carbon fiber oxidation furnace. By manufacturing the simulation device, on-site personnel can be separated from on-site production, the practice frequency is increased, and the safety of the production site can be ensured.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present utility model is as follows:

[0008] A plurality of simulation rollers, with a part of the simulation rollers mounted on one of the mounting sides of the mounting frame and the other part of the simulation rollers mounted on the other mounting side of the mounting frame;

[0009] A first tension roller and a second tension roller, which are respectively mounted at the upper position and the lower position on the same mounting side of the mounting frame;

[0010] The carbon fiber wire bundle sequentially passes through the first tension roller, the simulation roller, the second tension roller and the first tension roller, and is connected end to end to form a closed loop; the driving mechanism drives the simulation roller, the first tension roller and the second tension roller to rotate to simulate the working process of the carbon fiber oxidation furnace.

[0011] Further, the simulation rollers are of the same specification, are staggeredly mounted on the two opposite mounting sides of the mounting frame, and the distance between two adjacent simulation rollers on the same side is the same.

[0012] Advantageously, the design of misaligned installation of the simulation rollers on the opposite two installation sides of the mounting frame not only helps to precisely control the traveling path and tension distribution of the carbon fiber tow, but also reduces friction and damage, improving the accuracy and reliability of the simulation.

[0013] Further, the simulation rollers rotate at the same speed driven by the drive mechanism.

[0014] Advantageously, the design of the same specifications of the simulation rollers, the same spacing between two adjacent simulation rollers on the same side, and rotation at the same speed together enhances the performance and reliability of the simulation device.

[0015] Further, the axial directions of both the first tension roller and the second tension roller are the same as that of the simulation roller.

[0016] Further, the first tension roller is mounted on the mounting frame through a bearing seat, and the mounting position of the first tension roller on the mounting frame can be adjusted through the bearing seat.

[0017] Advantageously, the up-and-down arrangement of the first tension roller and the second tension roller, the relative position relationship with the simulation roller, and the design of installation through the bearing seat and the adjustable position of the first tension roller together enhance the accuracy and flexibility of the simulation device when simulating the working state of the carbon fiber oxidation furnace.

[0018] Further, the simulation rollers, the first tension roller, the second tension roller, and the drive mechanism are connected to each other through gears and chains.

[0019] Further, the carbon fiber oxidation furnace simulation device is further provided with: a tension detector for detecting the tension value of the carbon fiber tow; and judging whether to adjust the position of the first tension roller on the mounting frame according to the tension value of the carbon fiber tow detected by the tension detector.

[0020] Further, the tension detector detects the tension value of the carbon fiber tow. If the detected tension value of the carbon fiber tow exceeds the preset tension value range, the position of the first tension roller on the mounting frame is changed by adjusting the bearing seat of the first tension roller to adjust the tension received by the carbon fiber tow.

[0021] Advantageously, by detecting and adjusting the position of the first tension roller on the mounting frame to adjust the tension of the carbon fiber tow, this simulation device can better simulate the actual working state of the carbon fiber oxidation furnace and provide more accurate data support for related research and tests.

[0022] Further, the carbon fiber oxidation furnace simulation device is further provided with a speed detection unit for monitoring the rotation speed of the simulation roller and judging whether to adjust the rotation speed of the simulation roller according to the monitoring result.

[0023] Furthermore, the speed detection unit monitors the rotation speed of the simulation roller. When the rotation speed exceeds the preset rotation speed range value, the rotation speed of the simulation roller is adjusted by adjusting the rotation speed of the drive mechanism.

[0024] Advantageously, the addition of the speed detection unit further improves the functionality and reliability of the carbon fiber oxidation furnace simulation device, providing a more accurate and stable simulation environment for related research and testing.

[0039] Such as Figure 1 And Figure 2As shown in the figure, the present utility model provides a carbon fiber oxidation furnace simulation device, including: an installation frame 300 with two opposite installation sides; a driving mechanism 500; a plurality of simulation rollers 100, part of the simulation rollers 100 are installed on one of the installation sides of the installation frame 300, and the other part of the simulation rollers 100 are installed on the other installation side of the installation frame 300; a first tension roller 210 and a second tension roller 220 are respectively installed at the upper position and the lower position on the same installation side of the installation frame 300; the carbon fiber tow sequentially passes through the first tension roller 210, the simulation roller 100, the second tension roller 220 and the first tension roller 210, and is connected end to end to form a closed loop; the driving mechanism drives the simulation roller 100, the first tension roller 210 and the second tension roller 220 to rotate to simulate the working process of the carbon fiber oxidation furnace.

[0040] In this embodiment, the carbon fiber oxidation furnace simulation device includes: an installation frame 300, simulation rollers 100, a first tension roller 210, a second tension roller 220 and a driving mechanism 500. The simulation rollers 100, the first tension roller 210, the second tension roller 220 and the driving mechanism 500 are all installed on the installation frame 300; the carbon fiber tow sequentially passes through the first tension roller 210, the simulation roller 100, the second tension roller 220 and the first tension roller 210, and is connected end to end to form a closed loop. The driving mechanism 500 drives the simulation roller 100, the first tension roller 210 and the second tension roller 220 to rotate, driving the carbon fiber tow to rotate to simulate the working process of the carbon fiber oxidation furnace.

[0041] In this embodiment, the carbon fiber oxidation furnace simulation device includes an installation frame 300, and simulation rollers 100, a first tension roller 210, a second tension roller 220 and a driving mechanism 500 installed on the opposite installation sides of the installation frame 300. When working, the driving mechanism 500 is started, and drives the simulation roller 100, the first tension roller 210 and the second tension roller 220 to rotate through a transmission mechanism. The carbon fiber travels along a predetermined path under the guidance of the simulation roller 100, the first tension roller 210 and the second tension roller 220 in the simulation device; meanwhile, the first tension roller 210 and the second tension roller 220 apply appropriate tension to the carbon fiber to simulate the tension state in actual production. The entire carbon fiber oxidation furnace simulation device simulates the working state of the carbon fiber oxidation furnace, providing convenience for related research and testing.

[0042] Further, the simulation rollers 100 have the same specifications, are installed in a staggered manner on the two opposite installation sides of the installation frame 300, and the distance between two adjacent simulation rollers 100 on the same side is the same.

[0043] Further, the simulation rollers 100 rotate at the same speed driven by the driving mechanism 500.

[0044] In this embodiment, the simulation rollers 100 are arranged on the opposite mounting sides of the mounting frame 300 with a dislocation, and the carbon fiber tow sequentially passes through the simulation rollers 100 arranged on the mounting frame 300. The dislocation-mounted simulation rollers 100 can ensure that the carbon fiber tow can smoothly transition from one simulation roller 100 to another during the traveling process, avoid twisting or winding of the tow, and can accurately control the traveling path and tension distribution of the carbon fiber tow.

[0045] In this embodiment, simulation rollers 100 of the same specification are provided, and the distances between two adjacent simulation rollers 100 on the same side are the same, and a driving mechanism 500 provides a driving force for the simulation rollers 100, so that the simulation rollers 100 rotate at the same speed. The simulation rollers 100 with the same size and the same rotation speed can further enhance the stability of the carbon fiber tow during the simulation process, as well as the control of the path and the distribution of the tension.

[0046] Further, the axial directions of the first tension roller 210, the second tension roller 220 and the simulation roller 100 are the same.

[0047] Further, the first tension roller 210 is mounted on the mounting frame 300 through a bearing seat 400, and the mounting position of the first tension roller 210 on the mounting frame 300 can be adjusted through the bearing seat 400.

[0048] In this embodiment, the first tension roller 210 and the second tension roller 220 are respectively arranged on the upper and lower sides of the simulation roller 100 on the same mounting side of the mounting frame 300, and both have the same axial direction as the simulation roller 100. Moreover, the first tension roller 210 is mounted on the mounting frame 300 through a bearing seat 400, and the mounting position of the first tension roller 210 on the mounting frame 300 can be adjusted through the bearing seat 400. The first tension roller 210 and the second tension roller 220 are arranged at the upper and lower parts on the same mounting side of the mounting frame 300, which helps to apply a stable vertical tension to the carbon fiber tow; and by respectively arranging the first tension roller 210 and the second tension roller 220 on the upper and lower sides of the simulation roller 100, the carbon fiber can be affected by the tension rollers before and after passing through the simulation roller 100, ensuring that the carbon fiber tow is always under the control of the tension during the traveling process, so as to simulate a more realistic working state of the carbon fiber oxidation furnace.

[0049] Further, the simulation roller 100, the first tension roller 210, the second tension roller 220 and the driving mechanism 500 are connected to each other through gears and chains.

[0050] In this embodiment, the driving mechanism 500, the simulation roller 100, the first tension roller 210 and the second tension roller 220 are connected by gears and chains. The driving force generated by the driving mechanism 500 is transmitted among the simulation roller 100, the first tension roller 210 and the second tension roller 220 through the gears and chains, and makes them rotate at a predetermined speed and in a predetermined direction. Meanwhile, the transmission efficiency of the gears and chains is high, which can reduce energy loss and improve the operation efficiency of the entire simulation device.

[0051] Further, the carbon fiber oxidation furnace simulation device is further provided with: a tension detector for detecting the tension value of the carbon fiber tow;

[0052] According to the tension value of the carbon fiber tow detected by the tension detector, it is judged whether to adjust the position of the first tension roller 210 on the mounting frame 300.

[0053] Further, the tension detector detects the tension value of the carbon fiber tow. If the detected tension value of the carbon fiber tow exceeds the preset tension value range, the position of the first tension roller 210 on the mounting frame 300 is changed by adjusting the bearing seat 400 of the first tension roller 210, so as to adjust the tension received by the carbon fiber tow.

[0054] In this embodiment, the carbon fiber oxidation furnace simulation device is further provided with a tension detector to detect the tension received by the carbon fiber tow, and judges whether to adjust the position of the first tension roller 210 according to the detected tension value, so as to adjust the tension applied by the first tension roller 210 on the carbon fiber tow.

[0055] Specifically, if the tension value detected by the tension detector is higher than the preset tension range, the distance between the two tension rollers is shortened by adjusting the bearing seat 400 of the first tension roller 210, so as to reduce the tension applied by the tension rollers on the carbon fiber tow and make it drop to the preset tension range; if the tension value detected by the tension detector is lower than the preset tension range, the distance between the two tension rollers is increased by adjusting the bearing seat 400 of the first tension roller 210, so as to increase the tension applied by the tension rollers on the carbon fiber tow and make it rise to the preset tension range; if the tension value detected by the tension detector is within the preset tension range, no adjustment is made, and the normal operation of the carbon fiber oxidation furnace simulation device is maintained, and the tension received by the carbon fiber tow is continuously detected during the operation.

[0056] Further, the carbon fiber oxidation furnace simulation device is further provided with a speed detection unit to monitor the rotation speed of the simulation roller 100, and judge whether to adjust the rotation speed of the simulation roller 100 according to the monitoring result.

[0057] Further, the speed detection unit monitors the rotation speed of the simulation roller 100. When the rotation speed exceeds the preset rotation speed range value, the rotation speed of the simulation roller 100 is adjusted by adjusting the rotation speed of the drive mechanism 500.

[0058] In this embodiment, the carbon fiber oxidation furnace simulation device is further provided with a speed detection unit to monitor the rotation speed of the simulation roller 100 and determine whether to adjust the rotation speed of the simulation roller 100 according to the monitoring result.

[0059] Specifically, the speed detection unit provided in the carbon fiber oxidation furnace simulation device monitors the rotation speed of the simulation roller 100. If the rotation speed is higher than the preset rotation speed range value, the rotation speed of the drive mechanism 500 is reduced to reduce the rotation speed of the simulation roller 100; if the rotation speed is lower than the preset rotation speed range value, the rotation speed of the drive mechanism 500 is increased to increase the rotation speed of the simulation roller 100; if the rotation speed is within the preset rotation speed range value, the carbon fiber oxidation furnace simulation device is operated at this rotation speed, and the rotation speed of the simulation roller 100 is monitored during the operation.

[0060] The carbon fiber oxidation furnace simulation device of the present invention can simulate the oxidation process of carbon fiber in the oxidation furnace, enabling post personnel to practice the handling of emergency problems in the oxidation furnace for a long time without being on-site for production. It can not only ensure the safety of the practice process, but also ensure the safety of the carbon fiber product production process and product quality. At the same time, a tension detector and a speed detection unit are provided, which can improve the accuracy and reliability of the entire simulation device and reduce the labor intensity of operators.
