The outer surface of the positioning shaft 4 is plugged with the environmentally friendly paper tube body 5. The control panel 3 starts the motor inside the equipment box 2 to rotate the positioning shaft 4, and the environmentally friendly paper tube body 5 rotates with the positioning shaft 4. After the operator adjusts the position of the cutting tool 7, the cutting tool 7 is started and pressed down to make the blade of the cutting tool 7 rotate to cut the rotating environmentally friendly paper tube body 5, so as to realize the annular cutting of the environmentally friendly paper tube body 5. A sliding rod 6 is fixedly connected to the side wall of the equipment box 2 near the top of the positioning shaft 4, and the cutting tool 7 is movably connected at the top position of the sliding rod 6. The workbench 1 is fixedly connected to the limit plate 8 at the top position away from the equipment box 2, and the sliding rod 6 is fixedly connected to the side wall of the limit plate 8 to support the sliding rod 6.

[0031] The outer surfaces of the two-way threaded rod 12 at symmetrical positions are movably connected with slides 13, and the two slides 13 are clamped with bearings 19 near the inner part of the two-way threaded rod 12. The bearings 19 are engaged with the outer surfaces of the two-way threaded rod 12, and the bearings 19 can drive the slides 13 to move when they move. Two limit rods 14 are inserted into the side walls of the two slides 13, and the two limit rods 14 are fixed on the side walls away from the two-way motor 11. The limit rods 14 pass through the side walls of the two slides 13 to limit the lateral displacement of the slides 13.

[0032] Four support rods 15 are symmetrically arranged on the side walls of the two slides 13 away from the bidirectional threaded rod 12, and limit blocks 16 are arranged at the top positions of the eight support rods 15. The eight limit blocks 16 are divided into four groups according to the horizontal position, and the top positions of the four groups of limit blocks 16 are fixedly connected with support plates 17, and the outer surfaces of the support plates 17 are fixedly connected with support pads 18.

The operator starts the motor inside the equipment box 2 by controlling the control panel 3 to rotate the positioning shaft 4, and the environmentally friendly paper tube body 5 rotates with the positioning shaft 4. After the operator adjusts the position of the cutting tool 7, the cutting tool 7 is started and pressed down to make the blade of the cutting tool 7 rotate and cut the rotating environmentally friendly paper tube body 5, which can realize the circular cutting of the environmentally friendly paper tube body 5, and then the cut paper tube is removed from the outer surface of the positioning shaft 4 to complete the cutting operation.

[0034] Secondly, when replacing the environmentally friendly paper tube body 5 with a different inner diameter, it is necessary to first insert the environmentally friendly paper tube body 5 into the outer surface of the positioning shaft 4, control the control panel 3 to start the bidirectional motor 11, and the bidirectional motor 11 drives the bidirectional threaded rod 12 to rotate, and the bidirectional threaded rod 12 drives the bearing 19 to move to the middle position. When the bearing 19 moves, it can drive the slide plate 13 to move. When the slide plate 13 moves, it pushes the support rod 15 to support outward, so that the support plate 17 moves away from the slot 10. When the support pad 18 is supported on the inner wall of the environmentally friendly paper tube body 5, the fixed limit of the environmentally friendly paper tube bodies 5 with different inner diameters can be achieved.

[0035] Finally, the support pad 18 is made of rubber, which is soft and can prevent scratches when the support plate 17 is in direct contact with the environmentally friendly paper tube body 5. The support pad 18 has a rough surface and a high friction coefficient, which can improve the stability of the environmentally friendly paper tube body 5 when it is fixed.
