When the fabric moves, it drives the tension roller 6 to rotate. At this time, the servo motor B74 can rotate. When the servo motor B74 rotates, it drives the rotating rod 73 to rotate. When the rotating rod 73 rotates, it drives the front and rear movable gears 72 to rotate synchronously. When the movable gears 72 rotate, they drive the rack plate 75 on the right side to move up and down synchronously. When the rack plate 75 moves, it drives the n-shaped plate 76 to move up and down. When the n-shaped plate 76 moves up and down, it drives the... The sliding blocks 77 on the front and rear sides move synchronously. As the sliding blocks 77 move, they drive the tension roller 6 via the fixed rod and tension sensor 78, thus adjusting the fabric tension. The tension sensor 78 monitors the change in fabric tension. Once the appropriate tension is achieved, a signal is transmitted to the control panel 8. The control panel 8 then stops the servo motor B74. During conveying, the drive motor 585 can run. The drive motor 585 drives the first rotating shaft, which in turn drives the left rotating roller 3. The rotation of the left rotating roller 3, in turn, drives the right rotating roller 3 via the conveyor belt 4. Simultaneously, the conveyor belt 4 rotates synchronously. The rotation of the first rotating shaft drives the driving bevel gear 584, which in turn drives the driven bevel gear 583. The driven bevel gear 583 then drives the square tube 582. The square tube 582, in turn, drives the driving gear 58 via the square rod 581. The driving gear 58, in turn, drives the transmission rod via the driven gear 57. The transmission rod, in turn, drives the rotating bevel gear 56. The rotating bevel gear 56, in turn, drives the movable rod via the transmission bevel gear 55. The movable rod, in turn, drives the conveyor rollers. When the conveyor roller 51 rotates, it can cooperate with the conveyor belt 4 to convey the fabric. The height of the conveyor roller 51 can be adjusted as needed. The operation of the servo motor A54 can drive the front threaded rod 53 to rotate. Then, under the transmission of the synchronous belt 531, the front and rear threaded rods 53 will rotate synchronously. When the threaded rod 53 rotates, it will drive the adjacent movable block 52 to move up and down synchronously, which can drive the conveyor roller 51 to move up and down. When it moves, it will also drive the square rod 581 to slide in the inner cavity of the square tube 582 without affecting the rotation of the conveyor roller 51. After adjusting to a suitable height, the servo motor A54 can be stopped.
