[0002] During the production process of plastic pipes, the formed plastic pipes need to be cut by a cutting device to ensure that the pipes of appropriate length can be processed to meet production needs.
[0003] The Chinese utility model patent with publication number CN213259718U discloses a pipe processing and cutting device, including a support plate, a mounting tube, a splicing rod, an adjusting bolt, a fixing seat, a buffer protection adjusting pipe cutting frame structure, a sealing protection pipe debris cleaning protection box structure, a mounting plate, a control switch, a sliding rod, a slider, a connecting rod, a clamp and a handle, wherein the mounting tube is bolted to the right side of the support plate; the splicing rod is longitudinally plugged into the upper part of the inner side of the mounting tube; the adjusting bolt is threadedly connected to the connection between the mounting tube and the splicing rod; and the fixing seat is bolted to the upper part of the splicing rod. The utility model clamps the pipe by the clamp, and then the handle is held close to the cutting machine to cut the pipe.
[0004] However, the above utility model still has some shortcomings:
[0005] During the use of the utility model, after the clamp clamps the pipe, the slider drives the connecting rod, the clamp and the pipe to move in the horizontal direction to approach the cutting machine, thereby cutting the pipe. However, the cutting in the horizontal direction causes uneven force on the pipe, which causes deformation at the cutting position of the pipe, affecting the quality of the finished pipe.
[0006] In addition, after the pipe is clamped by the clamp and then cut by the cutting machine, the operator is required to support the pipe on both sides of the clamp to prevent the pipe from falling downward due to its own gravity during the cutting process, causing the pipe to break at the cutting position and generating burrs at the cutting position.

[0027] See also Figure 1-4 The utility model provides a technical solution: a cutting device for processing plastic pipes, comprising a main base 1, the top of the main base 1 is connected to a top plate 3 through a supporting column 2, a mounting seat 4 is fixedly installed on the top of the main base 1, a circular ring box 5 is rotatably installed on the mounting seat 4, a plurality of external teeth 6 are fixedly connected to the curved side wall of the circular ring box 5, the circular ring box 5 is connected to a driving component 7 through the external teeth 6, and a mounting groove 8 is opened in the circular ring box 5, a plurality of gear sets 9 are installed in the mounting groove 8, a rack plate 10 is connected between every two adjacent gear sets 9, a sliding hole 20 is opened on the inner side wall of the circular ring box 5, the rack plate 10 is slidably arranged in the sliding hole 20, and a cutting blade 11 is fixedly connected to the inner side wall of the rack plate 10.
[0028] Specifically, the mounting seat 4 is provided with the same holes as those on the annular box 5, so as to facilitate the passage of the pipe to be cut; the driving assembly 7 can drive the outer teeth 6 to drive the annular box 5 to rotate, and simultaneously drive the rack plate 10 and the cutting blade 11 to cut so as to perform rotational cutting on the outer side wall of the pipe, thereby ensuring that during the cutting process, the outer side wall of the pipe can be subjected to uniform force, and ensuring that no deformation occurs at the cutting position of the pipe.
[0029] Furthermore, each gear set 9 includes an even number of gears 91 meshing with each other, and each gear 91 is rotatably mounted in the mounting groove 8 through a mounting rod 92. One end of one of the mounting rods 92 passes through the inner wall of the mounting groove 8 and is connected to the output shaft end of the motor 12. The motor 12 is mounted on the straight side wall of the annular box 5.
[0030] like Figure 3 As shown, the second gear 91 is sleeved and installed on the side wall of the mounting rod 92, and the mounting rod 92 is rotatably installed on the inner wall of the mounting groove 8; the number of the second gears 91 is set to an even number, so that when one of the second gears 91 rotates, all the meshing rack plates 10 can drive the corresponding cutting blades 11 to move synchronously to the inside or outside (the side close to the axis of the ring box 5 is the inside, and the side away from the axis of the ring box 5 is the outside);
[0031] In this embodiment, three sets of gear groups 9 are arranged in the annular box 5, and four gears 91 are arranged in each set of gear groups 9; the motor 12 controls the corresponding mounting rod 92 to drive the gear 91 to rotate, so that the corresponding gear group 9 operates to control all the rack plates 10 to drive the corresponding cutting blades 11 to move, so that the cutting blades 11 can fit the outer surface of the pipe.
[0032] Furthermore, the driving assembly 7 includes a gear 71, the teeth of the gear 71 are meshed with the external teeth 6, and the gear 71 is sleeved and installed on the outer side wall of the connecting rod 72, and the connecting rod 72 is connected to the output shaft end of the motor 73.
[0033] Specifically, the motor 1 73 operates to control the connecting rod 72 to drive the gear 1 71 to rotate, and drives the annular box 5 to rotate through the external teeth 6 to cut the pipe.
[0034] Furthermore, electric push rods 13 are installed on both sides of the annular box 5 and at the bottom of the top plate 3.

A plurality of balls 19 are rotatably installed on the inner side wall of the semicircular seat 2 18.
[0036] like Figure 4 As shown, the setting of the semicircular seat 18 is used to receive the pipe material. When the pipe material is cut, it does not need to be held by the staff, so as to avoid the pipe material from breaking at the cutting position due to its own gravity during the cutting process; wherein the setting of the ball 19 reduces the friction between the semicircular seat 18 and the lower half of the curved surface of the pipe material, and at the same time facilitates the pipe material to slide along the axis direction of the semicircular seat 18. The staff does not need to lift the pipe material to adjust the position of the pipe material on the semicircular seat 18, so as to facilitate the movement of the pipe material for the next cutting;
[0037] The setting of the semicircular seat 15 cooperates with the semicircular seat 2 18 to clamp and fix the pipe, ensuring the stability of the pipe during the cutting process; in addition, the setting of the rubber pad 16, when the semicircular seat 15 clamps the pipe, the rubber pad 16 and the upper half of the curved surface of the pipe fit together, increasing the friction between the pipe and the semicircular seat 15, preventing the pipe from rotating during the cutting process, and further increasing the stability of the pipe during the cutting process;
[0038] The left and right sides of the annular box 5 are both provided with a semicircular seat 15 and a semicircular seat 2 18, which can simultaneously receive and fix the pipe to be cut and the cut pipe, further freeing the hands of the operator.
[0039] Working principle and use process of the utility model: After the utility model is installed, the cut pipe is placed on the semicircular seat 2 18 on the left side and pushed to the right side, passing through the mounting seat 4 and the ring box 5 in sequence until it moves to the semicircular seat 2 18 on the right side, and the cutting blade 11 is aligned with the part to be cut on the pipe;
[0040] Two electric push rods 13 control the mounting plate 14 to drive the semicircular seat 15 to move downward and clamp the pipe. The motor 2 12 controls the corresponding mounting rod 92 to drive the gear 2 91 to rotate, so that the corresponding gear set 9 operates to control all the rack plates 10 to drive the corresponding cutting blades 11 to move inward until the cutting blades 11 are attached to the outer surface of the pipe.
[0041] The motor 73 runs and controls the connecting rod 72 to drive the gear 71 to rotate, and drives the annular box 5 to rotate through the external teeth 6 to cut the pipe, ensuring that the force on the outer surface of the pipe is uniform during the cutting process to avoid deformation and ensure the quality of the pipe.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
