[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a cutting device for processing sewage pipes, comprising: a support box 1; a side fixing box 10 bolted to the top of the support box 1, with an inner rotating cylinder 15 rotatably arranged inside the side fixing box 10; a clamping slide 26 symmetrically slidably arranged inside the inner rotating cylinder 15, with a clamping block 18 bolted to the inner side of the clamping slide 26; a rotating rod 13 rotatably arranged inside the side fixing box 10, with a gear 14 fixedly connected to the outer side of the rotating rod 13, and multiple teeth 28 equidistantly fixed to the outer side of the inner rotating cylinder 15, meshing with the gear 14 and the teeth 28; two cylinders 2 (number one) bolted to the inside of the support box 1; a limiting guide rail 9 located at the top of the support box 1, with a movable slide 6 slidably arranged at the top of the limiting guide rail 9, and a cylinder 7 (number two) bolted to the top of the movable slide 6; a support part located at the output end of cylinders 2 (number one) and 7 (number two); and a pipe cutting part 27 located above the support box 1.

[0028] It should be noted that in this embodiment, the device supports the sewage pipe by driving the support base 4 with two cylinders 2 and 7. The output ends of the two cylinders 2 and 7 are all fixed to the support base 4. Two guide rollers 5 are symmetrically rotated on the inner side of the support base 4. When the sewage pipe is placed on the guide rollers 5, the guide rollers 5 can rotate with the movement of the sewage pipe to reduce friction and ensure that the sewage pipe can move smoothly during the support process. The bottom of the two support bases 4 is symmetrically fixed to a first limiting rod 3, which is slidably connected to the support box 1. The top of the other support base 4 is symmetrically fixed to a second limiting rod 8, which is slidably connected to the movable slide 6. This limiting structure ensures the stability of the support base 4 during movement, thereby ensuring accurate and reliable positioning of the sewage pipe during cutting, effectively improving cutting precision. The side fixing box 10 contains an inner rotating cylinder 15, with two fixed seats 17 symmetrically fixed to its outer side. A rotating ring 16 is fixed to the outer side of each fixed seat 17, rotatably connected to the side fixing box 10, providing stable support for the rotation of the inner rotating cylinder 15. Two clamping slides 26 are symmetrically slidably disposed inside the inner rotating cylinder 15 and slidably connected to one of the fixed seats 17. When the second servo motor 22 starts, it drives the bidirectional lead screw 19 to rotate, causing the two moving sliders 20 to move synchronously in opposite directions, thus driving the two clamping slides 26 to move synchronously in opposite directions. Clamping blocks 18 are bolted to the inner side of the clamping slides 26, enabling the clamping of sewage pipes of different diameters. The moving sliders 20 internally... The sliding mechanism has two limiting slide rods 21, which are fixed to the fixed base 17. These limiting slide rods 21 limit and guide the movement of the movable slider 20, ensuring the smoothness and accuracy of the movement. Both sides of the movable slider 20 are provided with accordion cloth 23 between it and the fixed base 17 to prevent debris from entering the fixed base 17 and affecting the operation of the equipment. When the first servo motor 12 is started, it provides power and drives the rotating rod 13 to rotate after being reduced in speed and torque by the reducer 11. The rotating rod 13 drives the gear 14 to rotate. The gear 14 drives the inner rotating cylinder 15 to rotate through meshing with the teeth 28, thereby realizing the rotation of the clamped sewage pipe and preparing for the subsequent ring cutting. The top of the support box 1 is bolted with a support frame 24. The pipe cutting part 27 is rotatably installed on the inner side of the support frame 24 through a rotating shaft. The pipe cutting part 27 includes a rotating bracket, a cutting disc, a pulley, a belt, a motor, a cylinder, and a connecting support.A cylinder is rotatably mounted on a support bracket on one side of the support housing 1 via a rotating shaft. The cylinder output is rotatably connected to the rotating bracket via the rotating shaft. The rotating bracket rotates inside the support frame 24 via the rotating shaft. When the motor starts, its output drives one of the pulleys inside the rotating bracket to rotate. This pulley is connected to another pulley connected to the cutting disc via a belt drive, thereby driving the other pulley to rotate. The other pulley drives the cutting disc to rotate. The cylinder output can drive the rotating bracket to rotate and adjust around the support frame 24, thereby adjusting the angle and position of the cutting disc. After the drain pipe is clamped and rotated to a suitable position, the position of the cutting disc is adjusted by the cylinder, so that the cutting disc cuts the clamped and positioned drain pipe. A protective cover is provided on one side of the pipe cutting section 27 to protect the cutting disc and improve operational safety. The support housing 1 has a debris collection channel 25 inside to collect debris generated during the cutting process.

[0029] The pipe cutting section 27 includes a rotating bracket, a cutting disc, pulleys, a belt, a motor, a cylinder, and a connecting support. A cylinder is rotatably mounted on the connecting support on one side of the support housing 1 via a rotating shaft. The output end of the cylinder is rotatably connected to the rotating bracket via a rotating shaft. The rotating bracket rotates on the inner side of the support frame 24 via a rotating shaft. The output end of the motor drives one of the pulleys inside the rotating bracket to rotate. One of the pulleys is connected to another pulley connected to the cutting disc via a belt drive, thereby driving the other pulley to rotate. The other pulley drives the cutting disc to rotate. The output end of the cylinder drives the rotating bracket to rotate and adjust around the support frame 24. The cutting disc cuts the sewage pipe after it has been clamped and positioned. A protective cover is also provided on one side of the pipe cutting section 27 to protect the cutting disc and improve safety.

[0030] The specific architecture and operating logic of the cylinder, electric motor and servo motor achieving coordinated control through an external controller in this application are consistent with the existing technology in this field. The servo motors used are all equipped with encoders, which can provide real-time feedback on the speed, position and other information of the servo motors. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.

[0031] In one embodiment, such as Figures 1 to 7 As shown, the support part includes a support base 4 and guide rollers 5. The output ends of the two cylinders 2 and 7 are all fixed to the support base 4. Two guide rollers 5 are symmetrically rotated on the inner side of the support base 4.

The top of the other support base 4 is symmetrically fixed to a second limiting rod 8, which is slidably connected to the movable slide 6.

[0032] It should be noted that in this embodiment, the support part drives the support base 4 through cylinder 2 and cylinder 7, and uses guide roller 5 to stably support the sewage pipe. At the same time, the first limiting rod 3 is slidably connected to the support box 1, and the second limiting rod 8 is slidably connected to the movable slide 6, which ensures the stability of the movement of the support base 4, thereby ensuring that the sewage pipe is accurately positioned and reliably fixed during the cutting process, and improving the cutting accuracy.

[0033] In one embodiment, such as Figures 1 to 7 As shown, two fixed seats 17 are symmetrically fixed to the outer side of the inner rotating cylinder 15.

Two movable sliders 20 are symmetrically installed on the outer side of the bidirectional lead screw 19. The movable sliders 20 are slidably connected to the fixed seat 17. One side of the movable slider 20 is fixedly connected to the clamping slide 26.

[0034] It should be noted that, in this embodiment, the two fixed seats 17 and the rotating ring 16 symmetrically fixed to the outer side of the inner rotating cylinder 15 are rotatably connected to the side fixed box 10, providing stable support for the rotation of the inner rotating cylinder 15. The two clamping slides 26 are slidably connected to one of the fixed seats 17, and are fixed to the clamping slides 26 through the two movable sliders 20 on the outer side of the bidirectional screw 19, so that when the bidirectional screw 19 rotates, it can drive the two clamping slides 26 to move synchronously in opposite directions, thereby realizing the clamping of sewage pipes of different diameters and improving the versatility of the equipment.

[0035] In one embodiment, such as Figures 1 to 7 As shown, a second servo motor 22 is bolted to one side of one of the fixed seats 17. The output end of the second servo motor 22 is fixedly connected to the bidirectional lead screw 19. Two limit slide rods 21 are symmetrically slidably arranged inside the movable slider 20. The limit slide rods 21 are fixedly connected to the fixed seat 17. Accordion cloth 23 is provided between both sides of the movable slider 20 and the fixed seat 17.

[0036] It should be noted that in this embodiment, the second servo motor 22 installed on one side of one of the fixed seats 17 provides power to the bidirectional lead screw 19 to realize the automatic movement of the clamping slide 26. The two limiting slide rods 21 that slide symmetrically inside the moving slider 20 are fixedly connected to the fixed seat 17, which plays a limiting and guiding role in the movement of the moving slider 20, ensuring the smoothness and accuracy of the movement.

[0037] In one embodiment, such as Figures 1 to 7 As shown, a support frame 24 is bolted to the top of the support box 1, and the pipe cutting part 27 is rotatably mounted on the inside of the support frame 24 via a rotating shaft. A miscellaneous channel 25 is provided inside the support box 1.

[0038] It should be noted that, in this embodiment, the support frame 24, which is bolted to the top of the support box 1, provides the mounting base for the pipe cutting part 27.

[0039] In one embodiment, such as Figures 1 to 7 As shown, a reducer 11 is installed on one side of the side fixing box 10. The output end of the reducer 11 is connected to the rotating rod 13. A first servo motor 12 is installed on one side of the side fixing box 10. The output end of the first servo motor 12 is connected to the input end of the reducer 11.

[0040] It should be noted that in this embodiment, a reducer 11 and a first servo motor 12 are installed on one side of the side fixing box 10. The first servo motor 12 provides power, which is reduced and increased in torque by the reducer 11 to drive the rotating rod 13 to rotate. In turn, the inner rotating cylinder 15 is driven to rotate through the meshing of the gear 14 and the teeth 28, thereby realizing the rotational cutting function of the sewage pipe and meeting different cutting requirements.
