[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 As shown, an embodiment of the present invention proposes a plastic pipe cutting device, which is driven by a conveying device to continuously move axially. The cutting device includes a dual-axis motor 4, a cutting disc 5, a telescopic rod 2, a controller, a base plate 1, a movable plate 3 and a connecting assembly. The base plate 1 is horizontally arranged, and a support frame is provided at the bottom of the base plate 1 so that the base plate 1 corresponds to the height of the plastic pipe 12. The movable plate 3 is a rectangular plate, and the movable plate 3 is slidably connected to the top surface of the base plate 1. The fixed section and the movable section of the telescopic rod 2 are fixedly connected to the base plate 1 and the movable plate 3 respectively, and the telescopic rod 2 is used to push the movable plate 3 to slide. The sliding direction of the movable plate 3 is parallel to the short side of the movable plate 3. The output shaft of the dual-axis motor 4 is horizontally arranged, and the dual-axis motor 4 is slidably connected to the top surface of the movable plate 3. The sliding direction of the dual-axis motor 4 is perpendicular to the sliding direction of the movable plate 3, and the sliding direction of the dual-axis motor 4 is parallel to the axis of the plastic pipe 12. The cutting disc 5 is fixedly connected to the output shaft of one end of the dual-axis motor 4. The connecting assembly is connected to the output shaft of the other end of the dual-axis motor 4 and the movable plate 3. The connecting assembly is used to move the dual-axis motor 4 on the movable plate 3. The controller is electrically connected to the telescopic rod 2 and the dual-axis motor 4. When the cutting disc 5 cuts the plastic pipe 12, the output shaft of one end of the dual-axis motor 4 passes through the connecting assembly, causing the dual-axis motor 4 to move on the movable plate 3 at a speed corresponding to the axial movement speed of the plastic pipe. The diameter of the plastic pipe 12 is cut by the cutting disc 5.
[0017] like Figure 2As shown, the connecting assembly preferably includes a first gear 6, a second gear 7, and a connecting frame 8. The first gear 6 is coaxially fixedly connected to one end of the output shaft of the dual-axis motor 4. The axis of the second gear 7 is vertically arranged and perpendicular to the axis of the first gear 6. The second gear 7 and the first gear 6 are both bevel gears that mesh with each other. The second gear 7 is provided with an extension shaft 15, which extends downward and is fixedly provided with a coaxial third gear 14. The movable plate 3 is provided with horizontally arranged bar teeth 11, and the third gear 14 meshes with the bar teeth 11. The connecting frame 8 is fixedly connected to the body of the dual-axis motor 4 and is rotatably connected to the extension shaft 15. When the output shaft of the dual-axis motor 4 rotates, it drives the first gear 6 to rotate, which in turn drives the second gear 7 and the third gear 14 to rotate. Since the third gear 14 meshes with the bar teeth 11, the dual-axis motor 4 moves when the third gear 14 rotates. In this embodiment, a reducer is provided at the end where the dual-axis motor 4 is connected to the connecting assembly.
[0018] Preferably, a sliding block 16 is provided at the bottom of the dual-axis motor 4, and a first sliding groove 9 is provided on the movable plate 3. The vertical section of the first sliding groove 9 is T-shaped, and the sliding block 16 is adapted to the first sliding groove 9. The bar teeth 11 are provided on one side of the first sliding groove 9. The second gear 7 is located below the bottom plane of the sliding block 16 and is smaller than the width of the sliding block 16. The third gear 14 is meshed with the bar teeth 11, so that when the dual-axis motor 4 body slides, the sliding block 16 is provided to reduce the wear of the dual-axis motor 4 caused by sliding. The sliding block 16 cooperates with the first sliding groove 9 so that the dual-axis motor 4 can perform stable linear motion.
[0019] Preferably, a second sliding groove 10 is provided on the top surface of the base plate 1, and a sliding member is provided on the bottom of the movable plate 3, which is adapted to fit into the second sliding groove 10. In this embodiment, the vertical cross-section of the second sliding groove 10 is T-shaped. When the telescopic rod 2 pushes the movable plate 3 to move, the second sliding groove 10 ensures more stable reciprocating movement of the movable plate 3.
[0020] Preferably, two telescopic rods 2 are provided, and the telescopic rods 2 are respectively arranged at both ends of one side of the movable plate 3 to avoid that the single telescopic rod 2 is unstable in pushing after the dual-axis motor 4 has an excessively long stroke and the length of the movable plate 3 is lengthened.
[0021] Preferably, a connecting sleeve 13 is fixedly mounted on the connecting frame 8. The connecting sleeve 13 is rotatably connected to the extension shaft 15. The connecting frame 8 passes through both sides of the first gear 6 and is fixedly connected to the main body of the dual-axis motor 4. The rotatable connection between the connecting sleeve 13 and the extension shaft 15 prevents the third gear 14 from deviating from the extension shaft 15 after being subjected to force, thereby affecting the meshing of the various gears.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
