[0028] Embodiment

[0029] Refer to Figures 1-4, this embodiment provides a bending device for the telescopic tube of a vacuum cleaner, including a bottom plate 1. On one side of the top of the bottom plate 1, a feeding mechanism 2 is provided, and on the other side, a bending mechanism 3 is provided. More specifically, the feeding mechanism 2 includes a platform 15 fixedly connected to the bottom plate 1. The platform 15 is used to place the tube. A bracket 16 is arranged on the platform 15. A sprocket 17 is rotatably connected to the bracket 16. A chain 18 is sleeved on the sprocket 17. The chain 18 is fixedly connected to a jaw cylinder 19. The output end of the jaw cylinder 19 is two jaws. To improve the stability of the jaw cylinder 19, a smooth shaft 35 is fixed to the bracket 16, and the smooth shaft 35 is slidably connected to the jaw cylinder 19. When in use, place the tube on the platform 15. The two jaws are respectively on the front and back sides of the tube. Operate the jaw cylinder 19 to make the jaws clamp the tube, and then make the sprocket 17 and the chain 18 act. The chain 18 drives the jaw cylinder 19 and the tube to slide along the smooth shaft 35, so as to push the tube to move;

[0030] A cutting mechanism 4 is arranged between the feeding mechanism 2 and the bending mechanism 3. More specifically, the cutting mechanism 4 includes a linear mechanism two 13 fixedly connected to the bottom plate 1. The output end of the linear mechanism two 13 is a cutting saw 14. By controlling the linear mechanism two 13, the cutting saw 14 can be controlled to move, so that the cutting saw 14 cuts off the tube;

[0031] A material taking mechanism 5 is arranged below the bending mechanism 3. More specifically, the bending mechanism 3 includes a fixing plate 6 fixedly connected to the bottom plate 1. A linear mechanism one 7 is fixed to the fixing plate 6. The output end of the linear mechanism one 7 is a semi-circular pressing plate 8. Two supporting wheels 9 are rotatably connected to the fixing plate 6. The two supporting wheels 9 are respectively on both sides of the pressing plate 8. Arc-shaped grooves are arranged on the surfaces of the pressing plate 8 and the supporting wheels 9 to limit the tube;

[0032] The material taking mechanism 5 includes a sliding plate 10 slidably connected to the bottom plate 1. A fourth linear mechanism 34 is fixed to the bottom plate 1, and the output end of the fourth linear mechanism 34 is connected to the sliding plate 10. Vertically, a first top block 11 and a second top block 12 are slidably connected to the sliding plate 10. Both the first top block 11 and the second top block 12 are provided with arc-shaped grooves for the pipeline to enter. And in order to adapt to the shape of the bent pipeline, the arc-shaped groove on the first top block 11 is arc-shaped, and the arc-shaped groove on the second top block 12 is inclined. The first top block 11 is located below the middle of the two support wheels 9, and the second top block 12 is located between the cutting mechanism 4 and one of the support wheels 9. More specifically, one end of a first telescopic rod 20 is fixed to the bottom end of the first top block 11. A first rotating shaft 21 is rotatably connected to the sliding plate 10. One end of a first driving rod 22 is fixed to the first rotating shaft 21. The other end of the first driving rod 22 is rotatably connected to one end of a second driving rod 23, and the other end of the second driving rod 23 is rotatably connected to the first top block 11. A first power mechanism 24 for driving its rotation is fixed to the end of the first rotating shaft 21. One end of a second telescopic rod 25 is fixed to the bottom end of the second top block 12. A second rotating shaft 26 is rotatably connected to the sliding plate 10. One end of a first pushing rod 27 is fixed to the second rotating shaft 26. The other end of the first pushing rod 27 is rotatably connected to one end of a second pushing rod 28, and the other end of the second pushing rod 28 is rotatably connected to the second top block 12. A second power mechanism 29 for driving its rotation is fixed to the end of the second rotating shaft 26. When in use, as Figure 3 shown, the first driving rod 22 and the second driving rod 23 form a V shape, and the first pushing rod 27 and the second pushing rod 28 form a V shape. When the first power mechanism 24 drives the first rotating shaft 21 to rotate, since the first top block 11 can only move longitudinally under the action of the first telescopic rod 20, under the action of the second driving rod 23, the first top block 11 can move up and down. Similarly, the second top block 12 moves up and down when the second power mechanism 29 acts. The purpose of such a setting is that the first driving rod 22 and the second driving rod 23, and the first pushing rod 27 and the second pushing rod 28 occupy a relatively small height, which is more convenient for arrangement.

[0033] As a preferred solution of the present invention, an electric telescopic rod 30 is also inclinedly arranged on the sliding plate 10. The electric telescopic rod 30 is located between the first top block 11 and the second top block 12. The output end of the electric telescopic rod 30 is a push plate 31, and the push plate 31 is inclined towards the first top block 11. By controlling the electric telescopic rod 30, the movement of the push plate 31 can be controlled.

[0034] As a preferred solution of the present invention, a third linear mechanism 32 is fixed to one end of the platform 15 close to the cutting mechanism 4. The output end of the third linear mechanism 32 is a clamping plate 33. Before cutting, operate the third linear mechanism 32 to make the clamping plate 33 press the pipeline, and then perform cutting, which can prevent the pipeline from shifting.

[0035] The utility model is a bending device for a telescopic tube of a vacuum cleaner. The working process is as follows: the tube is placed on a platform 15, and the two clamps are respectively located at the front and rear sides of the tube. The clamp cylinder 19 is operated to clamp the tube with the clamp, and then the sprocket 17 and the chain 18 are actuated. The chain 18 drives the clamp cylinder 19 and the tube to slide along the optical axis 35, thereby pushing the tube to move. When the tube is placed on the two supporting wheels 9, the chain 18 is stopped, the linear mechanism three 32 is operated to compress the tube, and then the linear mechanism two 13 is operated to move the cutting saw 14 to cut the tube. After cutting, the linear mechanism one 7 is operated to lower the pressing plate 8. Under the action of the two supporting wheels 9, the pressing plate 8 bends the pipe, both ends of the pipe are tilted upward, then operate the linear mechanism 1 7 to restore the pressure plate 8 to its initial position, the pipe is on the two support wheels 9, then operate the power mechanism 1 24 and the power mechanism 2 29 to make the top block 11 and the top block 2 12 contact with the bent pipe, and move the pipe upward to disengage it from the support wheels 9, then operate the linear mechanism 4 34 to move the sliding plate 10, the top block 11, the top block 2 12 and the pipe forward to stagger with the pressure plate 8, then operate the electric telescopic rod 30 to move the push plate 31, the push plate 31 pushes the bent pipe to rotate, the pipe disengages from the top block 2 12, and disengages from the top block 11 under the action of gravity to achieve material unloading.

[0036] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
