Description

Technical Field

[0001] The present application relates to the technical field of winding equipment, and in particular to a winding adjustment device. Background Art

[0002] Carbon fiber paper is a porous carbon / carbon composite material composed of carbon fiber and carbon matrix. Carbon fiber paper (hereinafter referred to as "carbon paper") is often used to process the gas diffusion layer (GDL) in proton exchange membrane fuel cells (PEMFC). As the supporting material of the diffusion layer of proton exchange membrane fuel cells (PEMFC), it has the dual functions of mass transfer and conductivity. It is currently an important matrix material of the gas diffusion layer. The structure and performance of carbon paper have an extremely important influence on the performance of proton exchange membrane fuel cells. Moreover, among various types of fuel cells, proton exchange membrane fuel cells (PEMFC) have attracted much attention in recent years due to their low operating temperature (about 80°C), high power density, fast startup, and fast response to load changes.

[0003] The finished carbon fiber paper needs to be rolled up for transportation, so a winding device is set in the production equipment to roll up the carbon fiber paper. During the rolling process, due to the long production line and the tension inside the carbon fiber paper, the conveying rate and the winding rate of the carbon fiber paper are easily inconsistent during rolling, resulting in excessive changes in the carbon fiber paper and causing damage. Therefore, an adjusting device that can automatically adjust the tension and the winding rate is urgently needed. Utility Model Content

[0004] In order to solve the problem in the prior art that the existing winding device has a constant speed during the winding process, which easily causes damage to the carbon fiber paper, the present application provides a winding adjustment device.

[0005] A winding adjustment device provided in the present application adopts the following technical solution: a winding adjustment device, including a bracket, a guide roller is rotatably arranged on the upper middle part of the bracket, a tension roller is rotatably arranged below the guide roller, a steering roller is rotatably arranged above one side of the tension roller, an adjustment component is arranged on the side of the tension roller close to the guide roller, the adjustment component includes an adjustment roller that can move up and down in a vertical direction, and a detection sensor for detecting the position of the adjustment roller is arranged on the side wall of the bracket.

During the winding process, when the winding speed is greater than the conveying rate of the carbon fiber paper, since the winding speed is faster and the production speed is slower, the carbon fiber paper between the guide roller and the tension roller is tightened, and the carbon fiber paper drives the adjusting roller to move upward. When the adjusting roller moves upward, the detection sensor detects the movement of the adjusting roller and transmits the signal to the control panel, and the control panel controls the tension roller and the winding device to reduce the speed to prevent excessive tension from being applied to the carbon fiber paper, causing damage to the carbon fiber paper.

[0012] By adopting the above technical solution, the counterweight assembly is arranged at one end of the rotating shaft. The position of the counterweight assembly on the connecting plate can be adjusted by rotating the screw rod by the handle, thereby changing the magnitude of the force required to drive the adjusting roller to move, so that the adjusting roller can meet the adjustment requirements under different working conditions.

[0013] Optionally, a limiting component for blocking and limiting the adjusting roller is provided on the side wall of the bracket.

[0014] By adopting the above technical solution, the limiting assembly is used to limit the up and down movement of the adjusting roller, so as to prevent the adjusting roller from excessively moving during the adjustment process and causing damage to the carbon fiber paper.

[0018] By adopting the above technical solution, when the carbon fiber paper needs to be cut, the piston rod in the cylinder extends, and the piston rod drives the connecting rod to rotate downward around the connection with the fixed ring, and the connecting rod drives the blade to move downward, and the blade is attached to the surface of the steering roller.

[0035] The implementation principle of a winding adjustment device in this embodiment is:

[0036] The produced carbon fiber paper is pulled to the top of the guide roller 2, pulled downward by the guide roller 2, passed through the adjusting roller 63 and then pulled to the top of the first tension roller 3. The carbon fiber paper passes between the first tension roller 3 and the second tension roller 4 and then is pulled upward around the second tension roller 4 to the steering roller 5, and is pulled to the winding device through the steering roller 5. During the winding process, the first tension roller 3 and the second tension roller 4 transport the carbon fiber paper in an S shape, so that the tension in the carbon fiber paper on both sides of the tension roller is different, and the tension of the carbon fiber paper between the tension roller and the steering roller 5 is constant. When the winding rate is greater than the conveying rate at the production end, due to the faster rotation speed of the tension roller, the tension between the tension roller and the guide roller 2 becomes larger, and the carbon fiber paper is tightened under the action of the tension, driving the adjusting roller 63 to move upward around the rotating shaft 64, and the adjusting roller 63 moves upward. The position of the inspection When the detection sensor 7 detects that the adjusting roller 63 moves upward, it transmits a signal to the control panel. The control panel controls the speed of the tension roller and the winding device to decrease, so that the tension in the carbon fiber paper between the guide roller 2 and the tension roller is reduced, and the adjusting roller 63 is reset under the action of gravity, so that the conveying rate at the production end is consistent with the winding rate of the winding device, thereby improving the winding efficiency. Similarly, when the winding rate of the winding device is lower than the conveying rate at the production end, the tension in the carbon fiber paper between the guide roller 2 and the tension roller is reduced, and the adjusting roller 63 moves downward under the action of gravity. When the detection sensor 7 detects that the adjusting roller 63 moves downward, it transmits a signal to the control panel. The control panel controls the speed of the tension roller and the winding device to increase, so that the conveying rate at the production end is consistent with the winding rate of the winding device, thereby improving the winding efficiency.

[0037] In summary, in the present application, an adjustment roller that can move up and down is set on one side of the tension roller. When the speed of the production end is inconsistent with the speed of the winding, the tension between the guide roller and the tension roller changes, thereby driving the position of the adjustment roller to change. By detecting the position of the adjustment roller and controlling the rotation speed of the tension roller and the winding roller, the winding process is automatically adjusted, which avoids damage to the carbon fiber paper during the winding process, improves the efficiency and quality of the winding, and the device has a simple structure and is easy to use. Therefore, the present application effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.
