Embodiment 1
[0033] Embodiment 1 is a fixed-point adjustment device. As shown in Figure 1: belt-shaped moving object tension difference adjustment correction equipment, there are offset sensors, tension rollers and tension drive devices connected to both ends of the tension rollers, and tension control connected to the offset sensors device, the tension adjusting device is connected with the tension driving device through the tension control device. The specific structure can be as shown in Figure 2: the offset sensor is a travel switch 1 arranged on the frame, the tension driving device is a cylinder 2,3, and the tension regulating device is a pressure reducing valve 4,5. The tension control device is electromagnetic valve 6,7.
[0034] The specific connection mode is: the air compressor 16, the filter 17, the switch valve 18 are connected, the output of the switch valve 18 is connected with the pressure reducing valve 4,5 respectively, and the output of the pressure reducing valve 4,5 i...
Embodiment 2
[0038] Embodiment 2 is a continuous adjustment device. As shown in Figure 1: The belt-shaped moving object tension difference adjustment correction device has an offset sensor, and a tension control device is connected to the offset sensor. The tension adjustment device communicates with the tension force through the tension control device. The drives are connected.
