[0037] When cutting pipes, the adjustment of the cutting length of pipes in traditional equipment usually relies on complex manual positioning mechanisms, which are cumbersome to operate and difficult to achieve precise segmented cutting. Moreover, although some automated equipment adopts a multi-station design, it lacks a coordinated control mechanism for pipe conveying and cutting actions, resulting in redundant equipment structures and high risks of motion interference, making it difficult to achieve efficient continuous operation in a compact space.

[0038] An embodiment of the present invention provides a pipe cutting device, as Figure 1-4 shown, which includes a bottom plate 1, a roller 2, a cutting device 3, a rotating assembly 4, a lifting assembly 5, and a conveying assembly 6. The roller 2 is axially provided with a plurality of accommodating chambers, and pipes are placed in all the plurality of accommodating chambers. The roller 2 is arranged on the bottom plate 1, and the pipes are arranged parallel to the bottom plate 1. The fixed end of the cutting device 3 is connected to the bottom plate 1, and the movable end of the cutting device 3 is arranged on one side of the roller 2. The cutting device 3 is configured to cut the pipes. The fixed end of the rotating assembly 4 is connected to the bottom plate 1, the first movable end of the rotating assembly 4 is connected to the roller 2, and it is configured to drive the roller 2 to rotate.

[0039] Exemplarily, the pipe cutting device 3 is provided with two lifting assemblies 5 and two conveying assemblies 6. The two lifting assemblies 5 are respectively arranged at both ends of the roller 2. Two lifting grooves 21 are axially formed on the roller 2, and the two lifting grooves 21 respectively correspond to the positions of the two lifting assemblies 5. The conveying assembly 6 includes a rotating shaft 61 and a conveying wheel 62. One of the rotating shafts 61 is rotatably connected to the corresponding lifting assembly 5, and one of the conveying wheels 62 is sleeved on this rotating shaft 61 and connected thereto, and it can move in one of the lifting grooves 21. The other rotating shaft 61 is rotatably connected to the corresponding lifting assembly 5, and the other conveying wheel 62 is sleeved on this rotating shaft 61 and connected thereto, and it can move in the other lifting groove 21. By the forward and reverse rotation of the rotating assembly 4, the function of fixing or releasing the pipes by the conveying wheel 62 is realized.

[0040] Exemplarily, the second driving member 63 can drive the conveying wheel 62 to rotate, so as to achieve the technical effect that the conveying wheel 62 drives the pipes to move.

[0041] Exemplarily, the rotating assembly 4 has two rotating states. When the rotating assembly 4 rotates forward, the automatic indexing of the drum 2 can be achieved, and the lifting assembly 5 can move radially along the drum 2. When the rotating assembly 4 rotates in reverse, the drum 2 does not move, and the lifting assembly 5 can move radially along the drum 2; the function of fixing or releasing the pipe is realized, and the continuous switching of the pipe can be completed.

[0042] In the embodiment of the present application, as Figure 1-4 shown, the rotating assembly 4 includes a first driving member 41, a ratchet wheel 42, a ratchet tooth 43, a first elastic member 44, a main shaft 45, and a cam 46; the fixed end of the first driving member 41 is connected to the bottom plate 1, and the output end of the first driving member 41 is connected to the main shaft 45; the ratchet wheel 42 and the cam 46 are sequentially sleeved on the main shaft 45 and are both connected to the main shaft 45; one end of the ratchet tooth 43 abuts against one side of a tooth of the ratchet wheel 42, and the other end of the ratchet tooth 43 is rotatably connected to the drum 2; one end of the first elastic member 44 is connected to the drum 2, and the other end of the first elastic member 44 is connected to the ratchet tooth 43; the cam 46 abuts against the lifting assembly 5; when the first driving member 41 rotates forward, the ratchet wheel 42 drives the drum 2 to rotate through the ratchet tooth 43, and the cam 46 drives the lifting assembly 5 to move in a direction close to the main shaft 45; when the first driving member 41 rotates in reverse, the cam 46 drives the lifting assembly 5 to move in a direction close to the pipe, and the ratchet tooth 43 disengages from the engagement with the ratchet wheel 42, and the first elastic member 44 is in a compressed state, and the drum 2 stops rotating.

[0043] Exemplarily, the rotating assembly 4 is provided with two cams 46. The two cams 46 are arranged at intervals along the length direction of the main shaft 45.

[0044] Exemplarily, the cam 46 has a symmetric structure. The cam 46 is provided with a highest point and a lowest point. Four accommodating chambers are provided in the corresponding rolling member. When the first driving member 41 rotates forward, the main shaft 45 drives the ratchet 42 and the cam 46 to rotate forward. The ratchet 42 drives the roller 2 to rotate 90° through the ratchet teeth 43. At this time, the cam 46 also rotates 90°. During this process, the lifting assembly 5 moves in the direction close to the main shaft 45, so as to realize the function of loosening the pipe by the conveying wheel 62 when the roller 2 rotates; when the first driving member 41 rotates reversely, the main shaft 45 drives the ratchet 42 and the cam 46 to rotate reversely, the roller 2 does not move, and the cam 46 rotates 90°. During this process, the lifting assembly 5 moves in the direction away from the main shaft 45, so as to realize the function of fixing the pipe. The second driving member 63 can drive the conveying wheel 62 to rotate, so as to realize the function of the conveying wheel 62 conveying the pipe. It should be noted that the number of accommodating chambers is related to the shape setting of the cam 46, so as to ensure that when the first driving member 41 rotates forward, the rotation angle of the roller 2 just makes the next pipe located directly below the cutting machine 32, and the lifting assembly 5 is at the limit position closest to the main shaft 45.

[0045] In the embodiment of the present application, as Figure 1-4 shown, the lifting assembly 5 includes a support 51 and a second elastic member 52; one end of the support 51 abuts against the cam 46, and the other end of the support 51 is rotatably connected to the rotating shaft 61; one end of the second elastic member 52 is connected to the support 51, and the other end of the second elastic member 52 is connected to the roller 2.

[0049] Exemplarily, the air roller is connected to the rotating shaft 61, and the rotating shaft 61 is rotatably connected to the lifting assembly 5. When the inflatable roller 64 is inflated, it can flexibly clamp the pipe, thus avoiding damage to the pipe. After the inflatable roller 64 deflates, the pipe is precisely moved by the conveying wheel 62, which can ensure the consistency of the cutting length, thereby improving the accuracy of pipe cutting. By the forward and reverse rotation of the first driving member 41, the movement direction of the lifting assembly 5 can be controlled, so as to achieve the technical effect of fixing or releasing the pipe by the inflatable roller 64 during pipe cutting.

By the rotation of the gear, the movement of the gear on the rack can be realized, so that the movement of the slider 82 on the first slideway can be realized, and the third driving member drives the crankshaft to rotate, and the sliding of the crankshaft in the second slideway can realize the function of automatic limiting at the extreme position.
