Description

[0002] Carbon felt, as a novel carbonaceous material, has been widely used in environmental protection, energy storage, and other high-tech fields due to its advantages such as broad adsorption properties, large capacity, low resistance, and rapid adsorption. The production process of carbon felt typically involves multiple high-temperature treatment steps to ensure that its physical and chemical properties meet specific requirements.

[0003] Currently, the trimming process for charcoal felt mainly relies on manual or semi-automatic trimming devices. Traditional manual trimming methods are inefficient, labor-intensive, and struggle to guarantee uniformity and accuracy in the cuts. While existing semi-automatic trimming equipment partially solves these problems, it still has shortcomings.

[0004] Most existing trimming devices use a fixed unwinding and rewinding structure, which cannot be adjusted in real time according to the actual offset of the charcoal felt. When the charcoal felt shifts laterally during transport, if the position cannot be corrected in time, it will lead to uneven trimming on both sides, resulting in wavy edges or over-trimming.

[0040] The structure and function of this utility model:

[0041] The unwinding and correction system 1 includes:

[0042] Unwinding base 101: The unwinding base 101 serves as the support platform for the entire unwinding and correction system. Two parallel guide rails 1011 are provided on its upper part to support and guide the slider 1012. These guide rails ensure the translational movement of the unwinding support frame 102 in the left and right directions to accommodate the lateral offset of the carbon felt.

[0044] Translation drive component 103 includes:

[0045] Support 1031: Fixedly connected to unwinding support frame 102, serving as the mounting base for servo motor 1033 and other transmission components.

[0046] Planetary reducer 1032: Used to amplify the torque output of the servo motor and slow down the speed, thereby achieving smooth and precise displacement control.

[0047] Servo motor 1033: A high-precision, high-performance AC servo motor with position feedback function is selected to ensure that the position of the unwinding support frame can be adjusted in real time according to the signal provided by the laser sensor 2041.

[0048] Rack 1034 and gear 1036: The rack is fixed on the unwinding base 101, and the gear is installed on the output shaft of the planetary reducer. The two work together to realize the linear movement of the unwinding support frame.

[0049] Rack bracket 1035: Used to fix the rack, ensuring its straightness and parallelism, and preventing deformation or displacement caused by external forces.

[0050] Working principle: When the laser sensor detects that the edge of the carbon felt has shifted, the control system sends a command to the servo motor, which drives the unwinding support frame to move laterally along the guide rail through the gear and rack transmission system, ensuring the accuracy of the cutting process.

[0051] The winding and cutting mechanism 2 includes

[0052] Winding support frame 201: The winding support frame 201 is the core component of the winding and cutting mechanism. Symmetrically arranged at its upper end are guide frames 2011 for the winding rod 2012, which restricts the vertical movement of the winding rod and maintains the stability of the charcoal felt roll. In addition, the winding support frame is equipped with two drive rollers 2013, fixed by bearing seats 2014, ensuring stable rotation of the drive rollers to drive the charcoal felt roll.

[0053] The take-up drive component 202 includes:

[0054] Drive motor 2021: Adopts a high-efficiency and energy-saving DC motor, featuring high power output and fast response, to meet the winding requirements of carbon felt of different specifications.

[0055] RV reducer 2022: Used to reduce motor speed while increasing output torque, ensuring that the drive roller has enough power to pull the carbon felt.

[0056] Sprockets 2023 and chains 2024: The sprockets are fixed on the drive rollers and transmit the power of the motor to the drive rollers through the chain drive, so as to realize the continuous winding of the carbon felt.

[0057] After startup, the drive motor reduces speed and increases torque through an RV reducer, then drives the drive roller to rotate via a sprocket and chain system, thereby pulling the charcoal felt to wind up. Throughout the process, the motor speed can be adjusted according to actual needs to ensure that the winding speed matches the charcoal felt production speed.

[0058] Charcoal felt trimming assembly 203 includes:

[0059] Rubber-coated roller 2031: The rubber-coated roller 2031 is fixed to the winding support frame via bearing seat 2032 and connector 2033. There are two rubber-coated rollers 2031, which are set up vertically. The lower rubber-coated roller is in close contact with the drive roller and rotates synchronously with the help of friction to assist in the transmission of carbon felt.

[0060] Cutter holder 2034: Fixed to the winding support frame, cutter holder 2034 is equipped with guide rail 2036 and slider 2037 for supporting the left and right movement of the disc cutter 2035. Slider 2037 is also equipped with slider 3 2039 and guide rail 3 2040 for supporting the up and down movement of the disc cutter 2035. The design of the cutter holder allows the operator to adjust the position of the disc cutter left and right according to the required finished product width.

[0061] Disc cutter 2035: It is connected to the cutter connector 2038 by thread, and the cutter connector 2038 is fixedly connected to the guide rail 2040.

[0062] Laser correction component 204 includes:

[0063] Laser sensor 2041: Mounted on sensor bracket 2045, its position can be freely adjusted via guide rail 2043 and slider 2044 to ensure accurate detection of changes in the edge of the carbon felt.

[0064] Sensor connector 2042: Used to fix the laser sensor and ensure its stability during operation.

[0065] Sensor bracket 2045: Fixed to the winding support frame, it provides a stable mounting platform for the laser sensor.

[0066] Working principle: The laser sensor monitors the position information of the carbon felt edge in real time and transmits the data to the control system. If a deviation of the carbon felt is detected, the control system immediately triggers the translation drive component to adjust the position of the unwinding support frame, so that the carbon felt is re-centered. This process is achieved through a closed-loop control system, ensuring the timeliness and accuracy of the correction action.

[0067] Guide roller 4: The guide roller 4 is fixed on the winding support frame 201 by the diamond-shaped belt bearing 5. There are two guide rollers 4, which are arranged horizontally at intervals. They are mainly used to support and guide the carbon felt to ensure its stability during transmission.

[0068] This invention features an integrated control system that coordinates the operation of various subsystems. The system includes key components such as a PLC controller, a touchscreen interface, and servo drives, enabling comprehensive monitoring and automatic control of the unwinding, rewinding, cutting, and web guiding processes. Through preset parameters and algorithms, the control system dynamically adjusts the working status of each component according to actual production conditions, ensuring efficient operation of the entire process. Operators can easily set parameters such as the specifications of the carbon felt, cutting width, and rewinding speed through the touchscreen interface, and view the equipment's operating status and alarm information in real time. Furthermore, the system supports remote monitoring and fault diagnosis functions, facilitating daily management and troubleshooting by maintenance personnel.

[0069] The working process of this utility model is as follows:

[0070] Preparation: Install the carbon felt roll 3 on the air expansion shaft 1021, adjust the initial position, and ensure that the carbon felt can be wound onto the threading rod 2012 in sequence through the guide roller 4 and the rubber-coated roller 2031.

[0071] Parameter setting: Set the required specifications of the finished charcoal felt through the touch screen interface, including parameters such as cutting width and winding speed, and start the control system.

[0072] Unwinding correction: The servo motor 1033 adjusts the position of the unwinding support frame 102 in real time based on the feedback information provided by the laser sensor 2041 to prevent the carbon felt from shifting.

[0073] Winding and Cutting: The drive motor 2021 drives the drive roller 2013 to rotate and begin winding the charcoal felt; at the same time, the disc cutter 2035 precisely cuts both sides of the charcoal felt to ensure that the edges are neat and uniform.
