The handle 401 is fixedly connected to the upper surface of the adjusting rod 402, and the adjusting rod 402 is fixedly connected to the upper end of the lead screw 404. The adjusting rod 402 is located above the limiting plate 403, which is fixedly connected to the outer left side surface of the main wall panel 3. The lead screw 404 is threadedly connected to the inside of the limiting plate 403, and its lower end is rotatably connected to the inside of the limiting block 414. The guide groove 405 is fixedly connected to the outer left side surface of the main wall panel 3 and is located on the limiting plate. Below 403, the movable base plate 406 is slidably connected to the groove of the guide groove 405. The movable base plate 406 is threadedly connected to the outer surface of the lead screw 404. The motor bracket 407 is fixedly connected to the outer left side of the movable base plate 406. The stepper motor 408 is fixedly connected to the outer left side of the motor bracket 407. The pulley 409 is fixedly connected to the output end of the stepper motor 408. The synchronous pulley 411 is fixedly connected to the outer left side of the connecting shaft 412. The synchronous belt 410 is fitted on the outer surfaces of the pulley 409 and the synchronous pulley 411. The connecting shaft 412 is rotatably connected to the inside of the main wall plate 3. The main roller 413 is fixedly connected to the outer right side of the connecting shaft 412. The outer surface of the main roller 413 is fitted with the main belt 1. The limiting block 414 is fixedly connected to the outer left side of the main wall plate 3 near the bottom.

[0026] A tensioning and correction mechanism is provided, wherein a correction device 8 is provided on the lower surface of the belt support 2 near the rear edge. The correction device 8 includes a fixed block 801, a movable column 802 and a correction roller 803. The fixed block 801 is fixedly connected to the lower surface of the belt support 2 near the rear edge. The movable column 802 is slidably connected in the groove of the fixed block 801. The correction roller 803 is rotatably connected to the outer surface of the movable column 802. The outer surface of the correction roller 803 cooperates with the main belt 1.

[0027] Working principle: Rotating handle 401 drives adjusting rod 402 to rotate, which in turn drives lead screw 404 to rotate. Lead screw 404 then moves movable base plate 406 within guide groove 405. The movement of movable base plate 406 moves stepper motor 408 and synchronous pulley 411, which in turn moves connecting shaft 412. Connecting shaft 412 then moves main roller 413. Since the outer surface of main roller 413 engages with main belt 1, the tension of main belt 1 is adjusted. Rotating handle 401 clockwise loosens main belt 1, making it easier to remove and replace. Rotating handle 401 counterclockwise tightens main belt 1. The tension stops when main belt 1 reaches the appropriate level. Turning handle 401 starts the stepper motor 408, which drives pulley 409. Since pulley 409 and synchronous belt 410 cooperate, and synchronous belt 410 in turn cooperates with synchronous pulley 411, synchronous pulley 411 also rotates. Synchronous pulley 411 drives connecting shaft 412 to rotate, which in turn drives main roller 413 to rotate. Main roller 413 drives main belt 1 to rotate. When main belt 1 deviates, the corresponding moving column 802 is pulled to the side it deviates from. The movement of moving column 802 causes the correction roller 803 to move, and main belt 1 returns to its initial path under the influence of correction roller 803. At this point, moving column 802 can be reset. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
