[0011] In the figure, two pieces of vertical seat bearings 2 are respectively installed on the mounting base plates 1 on both sides and fixed with bolts. The middle shaft of the long aluminum guide roller 3 is installed on the vertical seat bearing 2, and the shaft holes match. The long aluminum guide roller 3 is fixed with the set screws on the vertical seat bearing 2 to prevent axial penetration. The square clamp 4 also matches the shaft hole of the long aluminum guide roller 3. The square clamp 4 is fixed to the long aluminum guide roller 3 using the set screws on the square clamp 4. Two cylinder swing arms 5 are respectively installed on the inner side of the square clamp 4 and fixed with screws. The end faces of both ends of the connecting shaft 8 are machined with threaded holes, which match the surface light holes of the cylinder swing arm 5 and are installed together with bolts. The middle light hole of the cylinder joint 9 is matched with the shaft hole clearance of the connecting shaft 8. The other end face of the cylinder joint 9 is machined with a threaded hole, which matches the external thread of the telescopic push rod end of the cylinder 10. The cylinder ear plate 11 is installed with the rear base of the cylinder 10 using a pin shaft, and the cylinder ear plate 11 is installed with the cylinder fixed seat 12 The cylinder fixing seat 12 is fixed on the supporting profile 13, and the supporting profile 13 is installed on the mounting base plate 1 and fixed by bolts. The upper and lower ends of the aluminum guide roller swing arm 6 are respectively installed on the square clamp block 4. The square clamp block below the aluminum guide roller swing arm 6 is also installed on the floating roller 7, and the fixing bolts on the square clamp block are used to fix it on the main shaft of the floating roller 7. Two L-shaped brackets 14 are installed on the mounting base plate 1. The tension sensor bracket 15 is installed at the mounting position below the side of the L-shaped bracket 14 and fixed with bolts. The tension sensor 16 is installed on the tension sensor bracket 15 and fixed with bolts. The tension roller 17 is installed on the tension sensor 16 at both ends and the shaft hole matches. The tension sensor 16 is connected to the PLC programmable controller. The T-shaped support 18 is installed at the mounting position above the side of the L-shaped support 14 and fixed with bolts. The short aluminum guide roller 19 is installed on the T-shaped support 18, and the shaft hole is assembled and clamped and fixed with the bolts on the T-shaped support 18.

[0012] During the release process, the material will exert pressure on the tension roller 17 (the pressure value reflects the tension value on the surface of the material). At this time, the pressure is applied to the tension sensor 16 through the tension roller 17. At this time, the tension sensor 16 will compare the detected tension value with the tension value set by the device itself, thereby adjusting the unwinding tension of the material unwinding device. However, time needs to be reflected during the material tension adjustment process, and rapid and timely adjustment cannot be achieved. At this time, the floating roller 7 will adjust its position state in the first time when the tension suddenly increases or decreases - lowering or raising, so that the material tension changes little, thereby ensuring constant material tension.
