Description

Technical Field

[0001] This utility model relates to the field of carbon felt production technology, and in particular to a tension winding device for carbon felt. Background Art

[0002] With the development of technology, carbon fiber, due to its excellent physical and chemical properties such as high strength, low weight, and corrosion resistance, has been widely used in many high-tech fields such as aerospace, automotive industry, and sporting goods. Carbon fiber usually exists in the form of carbon felt, which is a sheet material formed from carbon fiber through specific processes. In the production process of carbon felt, the continuous furnace is one of the key pieces of equipment, and the treatment of the winding end directly affects the quality of the final product and production efficiency.

[0003] Currently, most carbon felt manufacturers still use a relatively primitive manual rotating handle method for winding during continuous furnace production. This traditional method is not only inefficient, but also frequently results in the fabric roll being wound too tightly or too loosely due to differences in operator skill, seriously affecting product quality. Furthermore, manual winding also suffers from high labor intensity, high costs, and difficulty in ensuring consistency. Although some companies have attempted to use ordinary motors for automatic winding, the inability to precisely control winding speed and tension easily leads to the following problems:

[0004] Excessive speed: Excessive motor speed will cause the fabric roll to become increasingly taut, which may eventually break the fabric roll, resulting in material waste and production interruption.

[0005] Too slow speed: If the motor speed is too slow, the fabric roll will accumulate too much, causing wrinkles or even damage to the fabric roll, which will also affect product quality and production efficiency. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a tension winding device for carbon felt, aiming to solve the problems existing in the prior art by precisely controlling the tension during the winding process.

[0007] This utility model is achieved through the following technical solution: a tension winding device for charcoal felt, comprising a winding mechanism, the key technical points of which are: a tension control mechanism is provided at the front position of the winding mechanism; the tension control mechanism includes a tension platform frame; tension sensors are symmetrically arranged on the left and right sides of the upper part of the tension platform frame, and a middle bearing seat is fixedly arranged above the tension sensors; fixed plates are correspondingly arranged at the front and rear positions of the tension sensors and fixedly connected to the tension platform frame; an inverted bearing seat is fixedly arranged on the outside of the fixed plate; a guide roller is arranged between the middle bearing seat and the inverted bearing seat; a through hole is provided on the fixed plate for the guide roller to pass through; the height of the inverted bearing seat is lower than the height of the middle bearing seat; and a control alarm system is also provided on the tension platform frame.

[0008] Furthermore, the winding mechanism includes a winding platform frame, bearing seats fixedly mounted on the upper part of the winding platform frame, a winding roller disposed between the bearing seats, and a servo motor for controlling the rotation of the winding roller.

[0009] Furthermore, the control alarm system includes an electrical cabinet, a touch screen and alarm installed on the electrical cabinet, and a PLC controller and tension amplifier installed inside the electrical cabinet.

[0010] Compared with the prior art, the beneficial effects and features of this utility model are as follows:

[0011] Improved winding accuracy: By incorporating tension sensors and a tension control mechanism, the tension of the carbon felt during the winding process can be monitored and precisely controlled in real time. Especially under the control of a servo motor, the winding speed can be dynamically adjusted based on the feedback signal from the tension sensor, ensuring that the tension of the carbon felt remains within the set range and avoiding problems such as the roll being too tight or too loose due to uneven tension.

[0012] Improved production efficiency: Compared to traditional manual winding methods, this invention offers a higher degree of automation, reducing manual intervention and increasing production efficiency. Precise control of the servo motor ensures a smoother winding process, minimizing downtime and adjustment time caused by human error.

[0013] Reduced human error: Through the PLC controller and touchscreen interface, operators can easily set and monitor various parameters, reducing human error. Simultaneously, the alarm system can promptly issue alerts in case of abnormal tension, prompting operators to inspect and address the issue, further improving system reliability and safety.

[0021] The device mainly consists of two parts: a winding mechanism and a tension control mechanism.

[0022] I. Tension Control Mechanism

[0023] Tension platform frame 1: Serves as the support frame for the entire tension control mechanism, used for installing and securing other components.

[0024] Tension sensor 2: Two tension sensors 2 are symmetrically arranged on the upper left and right sides of the tension platform frame 1 to monitor the tension of the carbon felt in real time during the winding process. In this embodiment, the tension sensor selected is the Mitsubishi WZZC-2-30KG model, with a range of 0-30KG, which can meet the tension detection requirements of carbon felt of different thicknesses.

[0025] Central bearing seat 3: A central bearing seat 3 is fixedly installed on the upper part of each tension sensor 2 to support the guide roller.

[0026] Fixing plate 4: Fixing plates 4 are provided at the front and rear positions of tension sensor 2 and are fixedly connected to tension platform frame 1 to fix inverted bearing seat 5.

[0027] Inverted bearing seat 5: An inverted bearing seat 5 is fixedly installed on the outside of the fixed plate 4. Its height is lower than that of the middle bearing seat 3, and it is used to support the other end of the guide roller.

[0028] Guide rollers: Guide rollers are provided between the central bearing housing 3 and the inverted bearing housing 5, through which the carbon felt is guided and tension is adjusted. The fixed plate 4 is provided with through holes for the guide rollers to pass through.

[0029] Control and alarm system: A control and alarm system is also installed on the tension platform frame 1, including an electrical cabinet 10, a touch screen 11, an alarm 12, and a PLC controller and tension amplifier installed inside the electrical cabinet. The tension amplifier is a WFBS-4 model from the Kodi brand.

[0030] II. Receiving Organization

[0031] Rewinding platform frame 6: Serves as a support frame for the rewinding mechanism, used for mounting and securing other components.

[0032] Bearing seat 7: A bearing seat 7 is fixedly installed on the upper part of the winding platform frame 6 to support the winding roll 8.

[0033] Take-up roller 8: Located between two bearing seats 7, used for taking up carbon felt.

[0034] Servo motor: controls the rotation of the take-up roller 8. The winding speed and tension of the carbon felt are controlled by adjusting the speed of the servo motor.

[0035] The working principle of this utility model:

[0036] The operator sets the desired tension value, such as 5KG, via touchscreen 11. Tension sensor 2 monitors the tension of the carbon felt in real time and transmits the electrical signal to the tension amplifier. The tension amplifier amplifies the electrical signal and transmits it to the PLC controller. The PLC controller compares the received tension signal with the preset value and adjusts the servo motor speed through logical operations. When the tension exceeds the preset value (e.g., 10KG), the PLC controller immediately stops the servo motor and triggers alarm 12 to alert the operator to check for abnormalities.

[0037] How to use this utility model:

[0038] Preparation: Fix the guide rollers to the tension sensor 2 and calibrate the tension sensor 2 to ensure that the force on the tension sensor is 0KG when there is no fabric. Pass the charcoal felt 13, which will be removed from the continuous furnace processing end, through the three guide rollers and fix it to the winding roller 8 of the winding mechanism.

[0039] Parameter settings: The desired tension value is set via the touchscreen 11. In this embodiment, a 2.5mm thick carbon felt is selected, and the tension is set to 5KG. A PLC program is written to convert the electrical signal from the tension sensor 2 into a 0-30 digital signal via a tension amplifier, which is then transmitted to the PLC controller.

[0040] Operation Process: The servo motor is started to begin winding the charcoal felt. When the tension exceeds 5 kg, the PLC controller decelerates the servo motor to reduce the tension of the charcoal felt; when the tension is less than 5 kg, the PLC controller accelerates the servo motor to increase the tension of the charcoal felt. By continuously adjusting the speed of the servo motor, the tension of the charcoal felt is maintained at approximately 5 kg, ensuring the stability and quality of the winding process. If the tension exceeds 10 kg, the PLC controller will immediately stop the servo motor and trigger alarm 12, reminding the operator to check for material jamming or other abnormalities.
