[0003] When cutting pipes, most pipe cutting machines can only cut one at a time. Since different types of pipes have different diameters, the required fixing dimensions for the fixing and driving structures also vary. However, most existing cutting mechanisms are inconvenient for stably driving and fixing pipes of different diameters, and their cutting efficiency is low. Utility Model Content

A cutting cylinder is installed on one side of the cutting frame, and a cutting blade is fixed to the output end of the cutting cylinder. A cutting table is fixed inside the cutting frame on one side of the cutting blade. A slide rail is installed on the other side of the cutting blade and mounted on the side of the cutting frame. A support frame is fixed to the top surface of the cutting frame on the side of the cutting blade. Drive rollers are symmetrically rotatably connected inside the cutting frame below the support frame. The rear ends of the two drive rollers extend to the outside of the cutting frame and are connected via pulleys and belt drive. A motor is installed on the cutting frame behind one of the drive rollers, and the output end of the motor is fixed to the drive roller. Limiting rollers are installed above both drive rollers, and both ends of the limiting rollers are rotatably connected to moving screws via bearings. Each moving screw is slidably inserted into an adjustment groove in the support frame, and a fixing clamp is threaded onto the end of the moving screw extending to the outside of the support frame.

Sliding rods that are slidably inserted into the top of the fixed pressure plates on both sides of the servo cylinder are fixed to the top surface of the fixed pressure plates.

[0008] Preferably, a limiting guide plate is provided on the side of the cutting table away from the support frame, and a support plate is provided below the limiting guide plate. The support plate is adjustablely connected to the cutting machine frame. A servo cylinder is provided in the middle of the top surface of the support plate, and sleeves are fixed on the top surfaces of the support plate at both ends of the servo cylinder.

A cutting table 5 is fixed inside the cutting frame 1 on one side of the cutting blade 3. A slide rail 4 is located on the other side of the cutting blade 3 and is mounted on the side of the cutting frame 1. A support frame 6 is fixed to the top surface of the cutting frame 1 on the side of the cutting blade 3, and drive rollers 7 are symmetrically rotatably connected inside the cutting frame 1 below the support frame 6. The two drive rollers 7 are located behind... The end extends to the outside of the cutting frame 1 and is connected by a pulley and belt drive. A motor 8 is installed on the cutting frame 1 behind one side of the drive roller 7, and the output end of the motor 8 is fixed on the drive roller 7. A limit roller 9 is installed above both drive rollers 7, and both ends of the limit roller 9 are rotatably connected to a moving screw 10 through bearings. Both moving screws 10 are set as horizontally placed "I" shape. Each moving screw 10 is slidably inserted into the adjustment groove 11 opened in the support frame 6, and a fixing clamp 12 is threaded on the end of the moving screw 10 extending to the outside of the support frame 6.

[0024] The specific settings and functions of this embodiment are described below: The support frame 6 is configured as an inverted "U" shape that cooperates with the cutting machine frame 1. The top surfaces of the two drive rollers 7 are flush with the top surface of the support frame 6. An arc-shaped auxiliary groove is provided on the outer surface of the limiting roller 9 for limiting the pipe. A servo cylinder 13 is provided in the middle of the top surface of the support frame 6. A fixed pressure plate 22 is fixed at one end of the output end of the servo cylinder 13 that slides through into the inside of the support frame 6. The length of the fixed pressure plate 22 is less than the distance between the two limiting rollers 9. Sliding rods 14 that are slidably inserted into the top of the support frame 6 are fixed on the top surfaces of the fixed pressure plates 22 on both sides of the servo cylinder 13. The pipe is fixed by pressing the pipe down by the downward movement of the fixed pressure plate 22.

[0025] Example 2

[0026] like Figure 1-4 As shown, a limiting guide plate 20 is provided on the side of the cutting table 5 away from the support frame 6, and a support plate 15 is provided below the limiting guide plate 20. The support plate 15 is adjustablely connected to the cutting machine frame 1. A servo cylinder 19 is provided in the middle of the top surface of the support plate 15, and sleeves 21 are fixed on the top surfaces of the support plate 15 at both ends of the servo cylinder 19. Insert rods are fitted inside the two sleeves 21, and the top surfaces of the insert rods are fixed to the bottom surface of the limiting guide plate 20.

[0027] The overall effect of this embodiment is that the support plate 15 is symmetrically fixed with adjusting plates 16 on the side facing the cutting frame 1. The two adjusting plates 16 are slidably fitted with fixing screws 17, and the bottom surface of the fixing screws 17 is fixed to the bottom surface inside the cutting frame 1. The fixing screws 17 on the top surface of the two adjusting plates 16 are threaded with fixing nuts 18. The two support plates 15 are provided with sliding grooves that cooperate with the fixing screws 17. The diameter and width of the fixing nuts 18 are greater than the width of the sliding grooves. Each fixing screw 17 is set as a "T" shape to prevent the fixing nuts 18 from separating from the fixing screws 17. Through the movable design of the support plate 15, the distance between the limiting guide plate 20 and the cutting table 5 can be adjusted according to the cutting length.

[0028] The operating method and working principle of this device are as follows: When cutting pipes, first adjust the distance between the limiting roller 9 and the drive roller 7 according to the pipe's dimensions. During adjustment, tighten the fixing blocks 12 on both sides to release the clamping of the fixing blocks 12 onto the support frame 6, thereby pulling the limiting roller 9 to adjust the distance between the limiting roller 9 and the drive roller 7. After adjustment, tighten the fixing blocks 12 again to clamp the support frame 6. Then, tighten the fixing nut 18 to release the clamping of the fixing nut 18 onto the adjusting plate 16, thereby pulling the support plate 15 to adjust the distance between the limiting guide plate 20 and the cutting table 5. After adjustment, tighten the fixing nut 18 to re-fix it. During cutting, the servo cylinder 19 operates. Pushing the limiting guide plate 20 upwards so that it is located on the side of the top surface of the cutting table 5, the pipes are passed one by one between the limiting roller 9 and the drive roller 7, and the pipes are aligned with the arc groove of the limiting roller 9 so that the pipes abut against the limiting guide plate 20, thus realizing feeding and positioning. At this time, the servo cylinder 13 runs, driving the fixed pressure plate 22 to move down and press the pipes. The cutting cylinder 2 runs, driving the cutting blade 3 to move down to cut. After cutting, the servo cylinder 19 drives the limiting guide plate 20 to move down, the limiting of the pipes is released, the motor 8 runs, driving the drive roller 7 to continue to rotate, driving the pipes to feed, and pushing the cut pipes down. After pushing down, the servo cylinder 19 pushes the limiting guide plate 20 up again, so that the cutting operation can continue.
