[0032] As Figures 1-7 shown, a pusher mechanism for a pipe cutting machine includes:

[0033] A frame 1;

[0034] A pipe cutting component, which includes a first driving member 21, a cutter holder 22 and a cutter 23.

[0035] A pusher component, the pusher component includes a first pusher wheel set and a second pusher wheel set. The first pusher wheel set includes a first push belt 51 and two first pusher wheels 52. The two first pusher wheels 52 are rotatably installed on the frame 1, and the first push belt 51 is adapted to connect the two first pusher wheels 52;

[0036] The second pushing wheel set includes a second pushing belt 53 and two second pushing wheels 54. The two second pushing wheels 54 are rotatably installed on the frame 1, and the second pushing belt 53 is adapted to connect the two second pushing wheels 54;

[0037] The first pushing wheel set and the second pushing wheel set are arranged oppositely, and a pushing channel 55 adapted to pass through and clamp the pipe is formed between the first pushing belt 51 and the second pushing belt 53;

[0038] The stacking device includes a driving support 31, a stacking driving member 32 and a stacking box 33. The driving support 31 is installed on the frame 1, the stacking driving member 32 is installed on the driving support 31, the stacking box 33 is slidably fitted on the frame 1, the movable end of the stacking driving member 32 is connected to the stacking box 33, the stacking box 33 is provided with a placing groove 331, and the stacking driving member 32 is adapted to move the stacking box 33 on the frame 1 to collect the cut pipes.

[0039] In this embodiment, the moving direction of the cutting knife 23 is the same as the moving direction of the stacking box 33. The first pushing belt 51 and the second pushing belt 53 are provided with uniform protrusions adapted to increase the grasping force. The protrusions contact the surface of the pipe, increasing the friction between the first pushing belt 51 and the second pushing belt 53 and the pipe, and can effectively prevent the pipe from sliding or slipping during transportation, ensuring that the pipe can be stably transported to the cutting position.

[0040] Specifically, as Figure 3 shown, the pushing mechanism for the pipe cutting machine further includes a guiding component. The guiding component includes a first guiding plate 41. The first guiding plate 41 is installed on the frame 1, and the first guiding plate 41 is provided with a first guiding hole 411.

[0041] Specifically, as Figures 1-3 shown, an adjusting component is provided between the first pushing belt 51 and the second pushing belt 53. The adjusting component is adapted to be actuated to adjust the size of the pushing channel 55.

[0042] Specifically, as Figures 1-3As shown in the figure, the adjusting assembly includes an adjusting block group, a second driving member, a driving gear 63, a first rack 64 and a second rack 65. The adjusting block group includes a first adjusting block 61 and a second adjusting block 62. The first adjusting block 61 is adapted to abut against the first pushing belt 51, and the second adjusting block 62 is adapted to abut against the second pushing belt 53. The first rack 64 is mounted on the first adjusting block 61, and the second rack 65 is mounted on the second adjusting block 62. The driving gear 63 is mounted between the first rack 64 and the second rack 65. The driving gear 63 is adapted to mesh with the first rack 64 and the second rack 65. The movable end of the second driving member is connected to the driving gear 63.

[0043] In this embodiment, the second driving member can be a driving motor. The first adjusting block 61 and the second adjusting block 62 can be elastic blocks with a certain elasticity. The second driving member drives the driving gear 63 to rotate. The driving gear 63 meshes with the first rack 64 and the second rack 65. When the driving gear 63 rotates counterclockwise, it can drive the first rack 64 and the second rack 65 to move towards each other, thereby driving the first adjusting block 61 and the second adjusting block 62 to approach each other. The first adjusting block 61 abuts against and drives the first pushing belt 51 to move towards the second pushing belt 53, and the second adjusting block 62 abuts against and drives the second pushing belt 53 to move towards the first pushing belt 51. At this time, the pushing channel becomes narrower and can accommodate pipes with a smaller diameter.

[0044] When the driving gear 63 rotates clockwise, it can drive the first rack 64 and the second rack 65 to move away from each other, thereby driving the first adjusting block 61 and the second adjusting block 62 to separate from each other. The first pushing belt 51 and the second pushing belt 53 rebound to the initial state. At this time, the pushing channel returns to the initial state and can accommodate pipes with a larger diameter.

[0045] Specifically, as Figures 1-3 shown, the pushing member further includes a rotation driving mechanism adapted to drive the two first pushing wheels 52 and / or the two second pushing wheels 54 to rotate.

[0046] Specifically, as Figures 1-3 shown, the rotation driving mechanism includes a third driving member 71, a main transmission gear 72 and a slave transmission gear 73. The third driving member 71 is mounted on the frame 1. The main transmission gear 72 is connected to one of the second pushing wheels 54. The movable end of the third driving member 71 is connected to the main transmission gear 72. The slave transmission gear 73 is connected to one of the first pushing wheels 52. The main transmission gear 72 meshes with the slave transmission gear 73.

[0047] In this embodiment, the third driving member 71 can be a driving motor. The third driving member 71 drives the main transmission gear 72 to rotate clockwise. Since the main transmission gear 72 meshes with the driven transmission gear 73, the driven transmission gear 73 rotates counterclockwise. The main transmission gear 72 drives one of the second pushing wheels 54 to rotate clockwise, and the driven transmission gear 73 drives one of the first pushing wheels 52 to rotate counterclockwise, driving the first pushing belt 51 and the second pushing belt 53 to move towards the cutting knife 23, thereby pushing the pipe towards the cutting knife 23 for conveying.

[0048] Specifically, as Figures 1-5 shown, the guiding member further includes a second guiding frame 81. The second guiding frame 81 is installed on the frame 1, and a second guiding hole 82 is provided on the second guiding frame 81.

[0049] Specifically, as Figures 6-7 shown, an adjusting mechanism is provided on the second guiding hole 82. The adjusting mechanism includes a fourth driving member 83 and an adjusting plate 84. The fourth driving member 83 is adapted to drive the adjusting plate 84 to move to adjust the size of the second guiding hole 82 and clamp the pipe passing through the second guiding hole 82.

[0050] In this embodiment, the fourth driving member can be a driving cylinder.

[0051] Specifically, as Figures 1-5 shown, the guiding member further includes a guiding through pipe 9. The guiding through pipe 9 is installed on the frame 1, and a guiding channel is provided in the guiding through pipe 9. The guiding channel is adapted to convey the cut pipe to the stacking box 33.

[0052] Specifically, as Figures 1-5 shown, the stacking box 33 is slidably fitted on the frame 1 through at least one guide rail slider pair; wherein,

[0053] the guide rail slider pair includes:

[0054] a guide rail 34 installed on the frame 1;

[0055] a slider 35 installed on the stacking box 33.

[0056] In the present utility model, a pipe to be cut is conveyed to a pushing channel 55 between a first pushing wheel set and a second pushing wheel set through a first guide plate 41 by an external traction device. Concave-convex structures for increasing friction are provided on a first pushing belt 51 and a second pushing belt 53. The pipe is pushed into a second guide hole 82 by the first pushing belt 51 and the second pushing belt 53. A fourth driving member 83 on a second guide frame 81 is started to drive an adjusting plate 84 to move upward to reduce the size of the second guide hole 82 to clamp the pipe in the second guide hole 82. Subsequently, a first driving member 21 is started to drive a cutter 23 on a cutter holder 22 to move and cut the pipe. After the cutting is completed, the pipe falls into a placement groove 311 in a stacking box 32 through a guiding channel of a guiding through-pipe 9. A stacking driving member drives the stacking box 33 to reciprocate on a frame, and the moving direction of the stacking box 33 is the same as the moving direction of the cutter, so that the cut pipes are sequentially stacked in the placement groove. At this time, the fourth driving member 83 drives the adjusting plate 84 to move downward so that the pipe can move. The above process is repeated until the stacking box 33 is full.
