[0043] Please refer to Figure 5 and Figure 8 The conveying mechanism 6 includes a roller 61 and a driving member 62, the roller 61 is rotatably connected to the frame 2, and a plurality of grooves 16 are provided on the roller 61. The driving member 62 includes a first driving motor 621, a belt 622, a rotary drawer 623 and a connecting line 624. The first driving motor 621 is arranged on the frame 2, and the rotary drawer 623 is rotatably connected to the frame 2. The belt 622 is sleeved on the output shaft of the first driving motor 621 and the rotary drawer 623. The connecting line 624 is sleeved on the roller 61 and the rotary drawer 623. The limiting mechanism 7 includes a first limiting component 71 and a second limiting component 72. The first limiting component 71 includes a clamping plate 711, a first telescopic cylinder 712 and a first connecting plate 7 13. The first telescopic cylinder 712 is arranged on both sides of the frame 2. The first connecting plate 713 is connected to the output shaft of the first telescopic cylinder 712. The clamping plate 711 is connected to one end of the first connecting plate 713. The second limiting assembly 72 is arranged on the clamping plate 711, and the second limiting assembly 72 is used to limit the pipe. The second limiting assembly 72 includes a fixed plate 721, a first spring 722 and a limiting plate 723. The fixed plate 721 is fixedly connected to the top of the clamping plate 711.

The second limiting assembly 72 is provided with multiple groups.

[0044] With such arrangement, when a user uses an automatic pipe cutting machine, the user first places the pipe into the groove 16 provided on the roller 61 through the second through hole 4, and then the user starts the first telescopic cylinder 712, and the first telescopic cylinder 712 drives the first connecting plate 713 to move, and the first connecting plate 713 drives the clamping plate 711 to move toward the direction of the pipe, and when it reaches a suitable position, the first telescopic cylinder 712 is stopped, and the limiting plate 723 limits the pipe located on the groove 16 under the action of the first spring 722 to prevent the pipe from detaching from the groove 16, thereby improving the stability of the pipe, improving the safety, preventing damage to the subsequent cutting of the pipe, and improving the work efficiency, and then the user starts the first driving motor 621, and the first driving motor 621 is driven to move the first connecting plate 713. The motor 621 drives the belt 622 to rotate, the belt 622 drives the drawer 623 to rotate, the connecting line 624 rotates with the rotation of the drawer 623, and then the connecting line 624 drives the roller 61 to rotate.

It can ensure that the tube moves smoothly on the roller 61, avoid surface scratches or quality defects caused by vibration or impact, facilitate the subsequent cutting of the tube, and prevent the tube from slipping from the roller 61, thereby reducing the safety risk in the workplace.

The clamping plate 832 is connected to the output shaft of the second telescopic cylinder 831. The alignment assembly 84 includes a first screw rod 841, a second drive motor 842, a second sliding block 843 and a baffle 844. The first screw rod 841 is rotatably connected to the first sliding block 81.

[0046] With such arrangement, when the user uses the automatic pipe cutting machine, the user inputs the information of the pipe through the input module, and then the pipe moves toward the direction of the circular saw 91. At this time, the user starts the second drive motor 842 on the same side as the second through hole 4 through the console 5, and the second drive motor 842 drives the first screw rod 841 to rotate. As the first screw rod 841 rotates, the second sliding block 843 threadedly connected to the first screw rod 841 moves toward the direction of the roller 61. After the baffle 844 has completed its descent, the second drive motor 842 is stopped, and then the pipe moves, and one end of the pipe abuts against the baffle 844. When all the pipes of the roller 61 abut against the baffle 844, the user stops the first drive motor 621, and then moves the second sliding block 843 to the second sliding block 843. The baffle 844 on one side of the through hole 4 slides upward, which can align and ensure that the edge of the cut tube is neat and the size is accurate, so as to reduce cutting errors, improve the quality of tube cutting, avoid defects or quality problems caused by cutting deviations, and reduce material waste caused by cutting errors. The aligned tube can pass through the cutting machine more quickly, reducing the repeated adjustment time caused by improper position of the tube, thereby improving production efficiency. Then the user starts the first drive motor 621 again to move the tube on the roller 61. After the end of the tube close to the circular saw 91 passes through a small part of the circular saw 91, the first drive motor 621 is stopped, and the user makes the first sliding block 81 slide on the slide rail 82 to move the first sliding block 81 to the left side of the circular saw 91 Then the second drive motor 842 is started, and the second drive motor 842 drives the clamping plate 832 to move toward the direction of the pipe and fixes the pipe. Then the third drive motor 931 rotates the circular saw 91 through the second connecting plate 932, and the third telescopic cylinder 921 is started to drive the circular saw 91 to move toward the direction of the pipe. Because the pipe is hollow, when the circular saw 91 cuts the pipe, if the circular saw 91 cuts the pipe at a uniform speed, burrs may occur on the pipe, affecting the product quality. Therefore, the user inputs the radius and hardness coefficient of the pipe on the input module, and the input module transmits the information of the pipe to the processor. After processing, the processor controls the third telescopic cylinder 921, and the circular saw When cutting the pipe, the circular saw 91 contacts the outer circumference of the pipe. The contact area between the circular saw 91 and the pipe is small, but as the circular saw 91 moves, the contact area between the circular saw 91 and the pipe becomes larger and larger. The processor controls the third telescopic cylinder 921, and the third telescopic cylinder 921 controls the moving speed of the circular saw 91. Changing the speed gradient of the circular saw 91 can reduce local heat accumulation caused by friction and pressure concentration, which helps prevent material deformation and thermal stress. By adjusting the cutting speed, a smoother and more precise cutting edge can be obtained. Inconsistent speed can allow the cutting knife to adjust the cutting speed according to the characteristics of the material, so as to better adapt to the cutting needs of different materials. When cutting thinner parts of the pipe, using a lower cutting speed can save energy.Because it does not require too much force to overcome the resistance of the material, the wear of the tool can be reduced, thereby extending the service life of the tool. The part of one end of the pipe is cut off, so that the clamping plate 832 located on the left side of the circular saw 91 moves up and disengages from the pipe. Then the pipe moves again. After the laser rangefinder is used to obtain the required pipe length for processing, the first drive motor 621 is stopped. After the pipe moves to the transport block 1402, the first sliding block 81 on the left side of the circular saw 91 is displaced to the left side of the circular saw 91 through the slide rail 82, and the clamping plate 832 is moved to the left side of the circular saw 91 through the second telescopic cylinder 831. The pipe is clamped and fixed by the processor, and the processor sends a signal to the third telescopic cylinder 921 and the third drive motor 931 to drive the circular saw 91 to move toward the pipe and cut the pipe. After the cutting is completed, the clamping plate 832 on the left moves up and detaches from the pipe. The processor sends a signal to start the fourth drive motor 1403, and the fourth drive motor 1403 drives the second screw rod 1401 to rotate. The transport block 1402 threadedly connected to the second screw rod 1401 slides on the second screw rod 1401 and the second guide column 1404, and the pipe falls onto the feeding tray 12. The feeding tray 12 falls into the material box 13, and then the transport block 1402 continues to move to one side of the circular saw 91. After the movement is completed, the processor sends a signal to start the first drive motor 621, driving the tube to continue to move forward, and the laser rangefinder measures the distance of the tube. Repeat the above operation. After most of the tube is cut, the remaining tube can only be cut once. The laser rangefinder measures the distance of the tube. At the same time, the remaining tube moves forward, and the baffle 844 on the right side of the circular saw 91 drops to block the tube, and then the clamping plate 832 is pressed down to clamp and fix the tube. Afterwards, the circular saw 91 cuts the pipe. After the cutting is completed, the first sliding block 81 and the transport block 1402 move toward the feeding tray 12 at the same time, and then the clamping plate 832 located on the right side of the circular saw 91 moves up and separates from the pipe. The pipe separates from the transport block 1402 and falls into the material box 13. This can avoid the waste of pipe tails, process the pipe to the greatest extent, improve work output, improve work efficiency, make full use of processing materials, and control costs. The cover 11 is transparent, so that the user can observe the cutting status of the pipe at any time, which improves safety.

[0047] Embodiment 2:

[0048] The present application also provides a control method for an automatic pipe cutting machine. The control method for an automatic pipe cutting machine includes the following steps:

[0049] S1: The tube enters through the second through hole 4 and is placed on the groove 16 provided on the roller 61, and then the first driving motor 621 drives the tube to move forward;

[0050] S2: When the pipe moves, the second drive motor 842 drives the first screw rod 841 to rotate, and moves the baffle 844 toward the drum 61. The pipe is blocked by the baffle 844, and then the baffle 844 moves away from the drum 61. The pipe stops moving after passing through the circular saw 91. The circular saw 91 is driven by the third telescopic cylinder 921 and the third drive motor 931 to cut the protruding part of the pipe.

[0051] S3: After the cutting is completed, the pipe continues to move forward, passes through the laser rangefinder, and then moves to the transport block 1402, the laser rangefinder measures the distance, stops the first drive motor 621, and then the second telescopic cylinder 831 located on both sides of the circular saw 91 starts to drive the clamping plate 832 to press down to clamp the pipe, and then the third drive motor 931 drives the circular saw 91 to rotate, and the third telescopic cylinder 921 drives the circular saw 91 to move to cut the pipe;

[0052] S4: After the pipe is cut, the clamping plate 832 on the left side of the circular saw 91 moves up, the clamping plate 832 is separated from the pipe, the fourth driving motor 1403 drives the second screw rod 1401 to rotate, drives the transport block 1402 to slide on the second screw rod 1401, and moves the pipe to the feeding tray 12, and the clamping plate 832 moves up so that the pipe falls into the material box 13;

[0053] S5: When the pipe is being cut to the last part, the baffle 844 on the right side of the circular saw 91 descends to block the pipe, and then the clamping plate 832 clamps the pipe on the transport block 1402, and the circular saw 91 cuts the pipe.

[0054] Working principle: the pipe enters through the second through hole 4 and is placed on the groove 16 provided on the roller 61, and then the first driving motor 621 drives the pipe to move forward. When the pipe moves, the second driving motor 842 drives the first screw rod 841 to rotate, and moves the baffle 844 toward the roller 61. The pipe is blocked by the baffle 844, and then the baffle 844 moves away from the roller 61. The pipe stops moving after passing through the circular saw 91. The circular saw 91 is driven by the third telescopic cylinder 921 and the third driving motor 931 to cut the protruding part of the pipe. After the cutting is completed, the pipe continues to move forward, passes through the laser rangefinder, and then moves to the transport block 1402. The laser rangefinder measures the distance, stops the first driving motor 621, and then the second telescopic cylinders 831 located on both sides of the circular saw 91 The starting drives the clamping plate 832 to press down to clamp the pipe, and then the third driving motor 931 drives the circular saw 91 to rotate, and the third telescopic cylinder 921 drives the circular saw 91 to move to cut the pipe. After the pipe cutting is completed, the clamping plate 832 located on the left side of the circular saw 91 moves up, and the clamping plate 832 is separated from the pipe.
