[0023] Embodiment:

[0024] The corrugated pipe automatic non-chip cutting machine provided by the embodiments of the present utility model, as shown in Figures 1 to 3 includes a cutting dust-proof box 1 for corrugated pipes. A rotating plate 2 is rotatably connected inside the cutting dust-proof box 1. A servo motor I 3 is fixedly installed at the bottom of the cutting dust-proof box 1. The servo motor I 3 is connected to the rotating plate 2 through an output shaft. Support plates 4 are rotatably connected to both sides of the rotating plate 2. A cutting motor 5 is fixedly installed on the support plates 4. A cutting blade 6 is fixedly installed on the output shaft of the cutting motor 5. An electric push rod I 7 is rotatably connected to the rotating plate 2. The bottom of the electric push rod I 7 is rotatably installed on the rotating plate 2. With this structure, when the cutting motor 5 is started to drive the cutting blade 6 to rotate, and then the electric push rod I 7 is started to drive the support plate 4 to rotate downward, so that the cutting blade 6 moves downward to cut the corrugated pipe;

[0025] When the cutting disc 6 is worn, the servo motor 1 can be started to drive the rotating plate 2 to rotate, so that the cutting structure on the other side of the rotating plate 2 is transferred into the cutting cavity of the cutting dust-proof box 1. Then, the operator can replace the worn cutting disc 6 on the outside. The whole structure has a large operating space for replacing the cutting disc 6, which is convenient for replacement. Moreover, the cutting disc 6 can be replaced without stopping the machine, without delaying production, which is beneficial to improving the cutting efficiency of the corrugated pipe.

[0026] Reference Figures 1 to 3 As shown in the figure, a gantry frame 8 is fixedly connected to the top of the cutting dust-proof box 1. A lead screw 9 is rotatably connected to the upper part of the gantry frame 8. The lower end of the lead screw 9 is rotatably installed on the top of the cutting dust-proof box 1. A servo motor 2 10 is fixedly installed on the top of the gantry frame 8. The servo motor 2 10 is connected to the upper end of the lead screw 9 through an output shaft. A lifting plate 11 is threadedly connected to the lead screw 9. Two extension plates 12 are fixedly connected to the lifting plate 11. Sealing plates 13 are fixedly connected to both extension plates 12. Card slots 14 are formed on both sides of the sealing plate 13. One card slot 14 on the side of the sealing plate 13 is clamped with the rotating plate 2. Side plates 15 are fixedly connected to the opposite inner walls of the cutting dust-proof box 1. The other card slot 14 on the side of the sealing plate 13 is clamped with the side plate 15. In this structure, when the cutting disc 6 is rotated and switched in place, the servo motor 2 10 is started to drive the lead screw 9 to rotate at this time. The lead screw 9 drives the lifting plate 11 to move downward. At this time, the lifting plate 11 drives the sealing plate 13 on the extension plate 12 to move downward. At this time, the card slots 14 on both sides of the sealing plate 13 are respectively clamped with the side plate 15 and the rotating plate 2, so as to seal the space between the two sides of the rotating plate 2 and the cutting dust-proof box 1, thereby preventing cutting chips from overflowing from here and ensuring chip-free cutting of the corrugated pipe.

[0027] Reference Figures 1 to 3 As shown in the figure, a bottom frame 16 is fixedly connected to the bottom of the cutting dust-proof box 1. This structure uses the bottom frame 6 to support the entire cutting dust-proof box 1.

[0028] Reference Figure 1 As shown in the figure, a feed hole 17 is clamped on one side wall of the cutting dust-proof box 1. A discharge hole 18 opposite to the feed hole 17 is formed on the other side wall of the cutting dust-proof box 1. This structure uses the feed hole 2 to facilitate the corrugated pipe to extend into the cutting dust-proof box 1, and the discharge hole 18 facilitates the discharge of the corrugated pipe.

[0029] Reference Figures 1 to 3 As shown in the figure, a protective cover 19 is hinged to the cutting dust-proof box 1. Electric push rods 2 20 are rotatably connected to both sides of the protective cover 19. The bottoms of the electric push rods 2 20 are rotatably installed on the cutting dust-proof box 1. In this structure, when replacing the cutting disc 6, the electric push rod 2 20 is started to drive the protective cover 19 to rotate upward at this time, so as to open one side of the cutting dust-proof box 1, which is convenient for the operator to replace the cutting disc 6. At the same time, the protective cover 19 can ensure the safety of the operator during the replacement.

[0030] Reference Figures 1 to 3As shown, guide rods 21 are slidably connected to both sides of the lifting plate 11. The upper ends of the guide rods 21 are fixedly installed on the gantry 8, and the lower ends of the guide rods 21 are fixedly installed on the cutting dust-proof box 1. This structure uses the guide rods 21 to guide the movement of the lifting plate 11.

[0031] Reference Figures 1 to 3 As shown, two through holes 22 adapted to the cross-section of the sealing plate 13 are provided at the top of the cutting dust-proof box 1. The sealing plate 13 is slidably connected to the through holes 22. This structure of the through holes 22 facilitates the sealing plate 13 to extend into the cutting dust-proof box 1, and the adapted size design prevents chips from leaking at the gaps.

[0032] Reference Figures 1 to 3 As shown, a chip suction pipe 23 is connected to the bottom of the cutting dust-proof box 1, and a suction fan 24 is connected to the chip suction pipe 23. This structure starts the suction fan 24 to provide suction, so as to suck the waste chips from cutting the corrugated pipe into the chip suction pipe 23 and introduce them to a suitable collection place, thereby preventing the cutting dust-proof box 1 from scattering and realizing chip-free cutting.

[0033] It should be noted that: in the above embodiment, the cutting device is applied to drive the cutting by the corrugated pipe.

[0034] The implementation principle of the automatic chip-free cutting machine for corrugated pipes in the embodiment of the present application is as follows: When in use, start the cutting motor 5 to drive the cutting blade 6 to rotate, and then start the first electric push rod 7 to drive the support plate 4 to rotate downward, so that the cutting blade 6 moves downward to cut the corrugated pipe. During the cutting, start the suction fan 24 to provide suction, so as to suck the waste chips from cutting the corrugated pipe into the chip suction pipe 23 and introduce them to a suitable collection place, thereby preventing the cutting dust-proof box 1 from scattering and realizing chip-free cutting.

[0035] When the cutting blade 6 is worn, start the second servo motor 10 to drive the lead screw 9 to rotate at this time. The lead screw 9 drives the lifting plate 11 to move upward. At this time, the lifting plate 11 drives the sealing plate 13 on the extension plate 12 to move upward. Then start the first servo motor 3 to drive the rotating plate 2 to rotate, so as to transfer the cutting structure on the other side of the rotating plate 2 into the cutting cavity of the cutting dust-proof box 1. Then reverse-start the second servo motor 10 to drive the sealing plate 13 to move downward and return to its position. Then a new cutting blade can be used to continue cutting the corrugated pipe. During the cutting process, the operator can start the second electric push rod 20 to drive the protective cover 19 to rotate upward, so as to open one side of the cutting dust-proof box 1, which is convenient for the operator to replace the worn cutting blade 6. After replacement, close the protective cover 19, and then when the cutting blade 6 during cutting reaches the service limit, repeat the above operation.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
