[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 The utility model provides a technical solution: a paper tube cutting device, including a machine tool 1, on which a first roller 2 and a cutting mechanism 3 are provided. A rotating motor is provided at the end of the first roller 2, and the first roller 2 is driven to rotate by the rotating motor. A loading mechanism 4 and a unloading mechanism 5 are respectively provided at both ends of the first roller 2.

[0020] See also Figure 2-3The feeding mechanism 4 includes a plurality of rollers 41, which are symmetrically arranged on both sides of the first roller shaft 2. A fixed shaft 42 is provided on the roller 41, and the bottom of each fixed shaft 42 is fixed on a fixed plate 43. The fixed plates 43 are connected by a first telescopic rod 44, and the distance between the fixed plates 43 is changed by the telescopic movement of the first telescopic rod 44. A motor 45 is provided at the bottom of each fixed plate 43, and the motor 45 is connected to the fixed shaft 42. The fixed shaft 42 is driven by the motor 45 to rotate, thereby driving the rollers 41 to rotate. When feeding, the first telescopic rod 44 is shortened, and the distance between the fixed plates 43 is shortened, so that the rollers 41 on both sides of the first roller shaft 2 clamp the paper tube to be cut, and the paper tube is sleeved on the first roller shaft 2 by the rotation of the rollers 41. After the feeding is completed, the first telescopic rod 44 is extended, and the distance between the fixed plates 43 is lengthened. At this time, the rollers 41 release the paper tube.

[0021] See also Figure 4-5 The unloading mechanism 5 includes a linear motor 51, a moving platform 52 is provided on the linear motor 51, a folding rod 53 is provided on the moving platform 52, a unloading cylinder 54 is provided on the folding rod 53, and the unloading cylinder 54 is sleeved on the first roller 2. When unloading, the moving platform 52 moves on the linear motor 51, driving the unloading cylinder 54 to slide on the first roller 2, thereby pushing down the cut paper tube.

[0022] See also Figure 6 The cutting mechanism 3 includes a second roller 31, on which a plurality of cutting knives 32 are arranged, and connecting rods 33 are arranged at both ends of the second roller 31. The second roller 31 and the connecting rod 33 are movably connected, and the second roller 31 can rotate on the connecting rod 33. A second telescopic rod 34 is arranged on the connecting rod 33, and one end of the second roller 31 is provided with a rotating motor.
