The side wall of the front horizontal plate 2 is fixedly connected to a motor 6, and the output shaft of the motor 6 passes through the horizontal plate 2 and is rotatably connected thereto. The output shaft of the motor 6 is coaxially fixedly connected to the rotating roller 4 on the left, and can convey the packaging paper placed on the packaging paper conveyor belt 5.

[0022] A tensioning mechanism is provided on the rotating roller 4 on the right, and the tensioning mechanism includes a through hole set through each horizontal plate 2, and a slider 8 slidably connected thereto is provided in each through hole. The two ends of the rotating roller 4 on the right are rotatably connected to the two sliders 8 respectively, and each through hole is rotatably connected to a threaded rod 9. The front threaded rod 9 passes through the front horizontal plate 2 and is rotatably connected thereto, and one end of the front threaded rod 9 is fixedly connected to a handle 11, and the outer wall of the handle 11 is provided with a protective cover, and the material of the protective cover is rubber to increase comfort.

The outer wall of the threaded rod 9 and the inner wall of the through hole are respectively provided with matching external threads and internal threads. The outer walls of the two threaded rods 9 are jointly sleeved with a synchronous belt 10. The outer walls of the threaded rods 9 are fixedly connected with a synchronous pulley, and the synchronous belt 10 is sleeved on the outer walls of the two synchronous pulleys.

[0024] A detection mechanism is provided between the two horizontal plates 2, and the detection mechanism includes a fixed block 12 arranged on the top of each horizontal plate 2 and fixedly connected thereto, a front end of the fixed block 12 on the rear side is fixedly connected with a photoelectric sensor transmitter 13, and a rear end of the fixed block 12 on the front side is fixedly connected with a photoelectric sensor receiver 14, and the photoelectric sensor transmitter 13 and the photoelectric sensor receiver 14 are located below the upper packaging paper conveyor belt 5, and a signal is sent by the photoelectric sensor transmitter 13, and the photoelectric sensor receiver 14 receives the signal, so that it is known that the packaging paper conveyor belt 5 is tensioned. When the packaging paper conveyor belt 5 is loose, the photoelectric sensor receiver 14 is blocked from receiving the signal. At this time, an alarm light (electrically connected to the photoelectric sensor transmitter 13 and the photoelectric sensor receiver 14) set in the outside world gives an alarm to remind people that the packaging paper conveyor belt 5 is loose.

When the packaging paper conveyor belt 5 is loose, the packaging paper conveyor belt 5 will be blocked between the photoelectric sensor transmitter 13 and the photoelectric sensor receiver 14, so that the signal cannot be received. At this time, the staff member holds the handle 11 and rotates it to drive the front threaded rod 9, the synchronous belt 10, and the rear threaded rod 9 to rotate, so that the slider 8 slides on the inner wall of the through-hole, and then adjusts the position of the rotating roller 4 on the right side, and then adjusts the distance between the two rotating rollers 4, and adjusts the tension of the packaging paper conveyor belt 5 to ensure that the packaging paper conveyor belt 5 is straightened, which has a good effect on the transportation of packaging paper.
