[0021] After the paper roll is cut, it can be moved by the transmission roller 10. Another transmission wheel 3 is installed at one end of the transmission roller 10. The two transmission wheels 3 are jointly installed with a transmission belt 4. The pressing mechanism includes a baffle 7. Two brackets 5 are fixedly installed on the top surface of the base 1, and the rolling roller 6 is rotatably connected to the two brackets 5. The two brackets 5 are jointly installed with a baffle 7. A groove is opened in the baffle 7. A sponge pad 15 is slidably connected in the groove. A plurality of springs 14 are jointly installed on the bottom wall of the groove and the side of the sponge pad 15. The sponge pad 15 prevents the paper roll itself from being damaged during the rolling process.
[0022] A telescopic mechanism is provided in the cutting box 2, and the telescopic mechanism is connected to an assembly seat 13. A telescopic plate 18 is fixedly installed on the bottom surface of the assembly seat 13, and a cutting blade 20 is slidably connected in the assembly seat 13. The telescopic mechanism includes a support plate 12, and the support plate 12 is fixedly installed on the two side walls of the cutting box 2. A plurality of electric telescopic rods are fixedly installed on the bottom surface of the support plate 12, and the other end of each electric telescopic rod is fixedly installed on the top surface of the assembly seat 13. The height of the assembly seat 13 can be set by the electric telescopic rod. When the telescopic plate 18 is not in contact with the cutting seat 16, the cutting blade 20 is hidden. Cutting seats 16 are fixedly installed on the two side walls of the cutting box 2, and rollers 11 are rotatably connected to the two side walls of the cutting box 2. Through grooves 8 are provided on the corresponding sides of the cutting box 2, and the through grooves 8 can facilitate the placement of the paper roll path.
[0023] A driving mechanism is provided in the assembly seat 13, and the driving mechanism drives the cutting blade 20 to reciprocate. The driving mechanism includes a second motor 17, and the second motor 17 is fixedly mounted on one side of the assembly seat 13. A cavity is opened on the bottom surface of the assembly seat 13. The output shaft of the second motor 17 is connected to a threaded rod 19, and the other end of the threaded rod 19 is rotatably connected to the side wall of the cavity, and the cutting blade 20 is threadedly connected to the threaded rod 19. By starting the second motor 17, the threaded rod 19 can be driven to rotate, thereby moving the cutting blade 20. At the same time, the cutting blade 20 is slidably connected to the cavity opening, so that the cutting blade 20 cannot rotate, thereby limiting the cutting blade 20.
[0024] When the utility model is used, the staff first passes the external roll of paper through the through slot 8 opened on one side of the cutting box 2, and then passes it through the transmission roller 10 and the rotating roller 11. It is worth noting that at this time, the transmission roller 10 and the rotating roller 11 are both against the roll of paper, and then passes through the bottom of the assembly seat 13, and is fixed on the winding roller 6 from the side of the baffle 7, and then the first motor 9 is started, and the output shaft of the first motor 9 is connected to the transmission roller 10, thereby driving the transmission roller 10 to rotate, and then pushing the roll of paper forward. At the same time, the transmission roller 10 is connected to the winding roller 6 through a transmission belt mechanism, thereby driving the winding roller 6 to rotate, and then driving the roll of paper to be rolled on the winding roller 6.
[0025] It is worth mentioning that the paper roll passes through the side of the baffle 7, and a groove is opened in the baffle 7, and a plurality of springs 14 are installed together with the sponge pad 15 slidably connected with the groove on the baffle 7, so that the sponge pad 15 is against the paper roll, and the paper roll can be pressed when the paper roll is just rolled up to prevent it from being loosely rolled during the rolling process, and there is no need for manual pressing by the staff.
[0026] When the paper roll is completed, the electric telescopic rod on the bottom of the support plate 12 can be started, so that the assembly seat 13 moves downward until the telescopic plate 18 installed under the assembly seat 13 is against the cutting seat 16 fixedly installed in the cutting box 2. It should be noted that when the assembly seat 13 moves downward, the telescopic plate 18 is squeezed with the cutting seat 16, so that the cutting blade 20 is exposed and against the paper roll pressed by the telescopic plate 18, and then the cutting blade 20 pierces the paper roll, and then the second motor 17 is started to drive the threaded rod 19 to rotate, and then the cutting blade 20 threadedly connected to the threaded rod 19 is driven to cut the paper roll. This operation can hide the cutting blade 20 when there is no need to cut the paper roll, so as to prevent the staff from accidentally touching the cutting blade 20 when pulling the remaining paper roll and causing injury.
