[0030] Reference Figures 1 to 3 , which is a flower pot cutting machine of an embodiment of the utility model, comprises a machine base 100, two supporting rollers 200, a splitting mechanism 300 and a rotary drive mechanism 400. The two supporting rollers 200 are rotatably arranged on the machine base 100 and the rotation axes are parallel to each other. The supporting rollers 200 are arranged in the horizontal direction, the supporting rollers 200 are arranged at intervals and a workpiece receiving position is formed between two adjacent supporting rollers 200, and the supporting rollers 200 are provided with a fixed center convex portion 210; the splitting mechanism 300 is provided with a splitting knife 310, the splitting knife 310 is movably arranged on the machine base 100 and can approach or move away from the workpiece receiving position, and the splitting knife 310 is opposite to the fixed center convex portion 210; the rotary drive mechanism 400 is arranged on the machine base 100 and is used to drive the workpiece to rotate.

[0031] When placing the hollow part, the middle groove of the hollow part can be placed on the supporting roller 200 facing the fixed center convex part 210, so as to directly complete the positioning, and then the rotary drive mechanism 400 drives the workpiece to rotate, during which the dividing knife 310 of the dividing mechanism 300 moves toward the workpiece accommodating position, and gradually divides the rotating workpiece into two flower pots along the middle groove, and then the dividing knife 310 is reset, and the rotary drive mechanism 400 stops driving the workpiece to rotate, and the two flower pots can be taken off the supporting roller 200. The above-mentioned flower pot cutting machine completes the alignment of the dividing knife 310 and the middle groove of the hollow part during the process of placing the hollow part, which is simple to operate and has high production efficiency.

[0032] It is conceivable that in other embodiments, three or more support rollers 200 may be arranged at intervals, and those skilled in the art may configure the support rollers 200 according to actual needs. It is conceivable that some of the support rollers 200 may be provided with the centering convex portion 210, or all of the support rollers 200 may be provided with the centering convex portion 210.

[0033] In the embodiment, the centering convex portion 210 is an annular plate, and the annular plate is arranged around the outer circumference of the supporting roller 200. The centering convex portion 210 is an annular plate, which facilitates the support roller 200 to rotate to any angle. When the hollow part is placed on the support roller 200, the middle groove of the hollow part can also be directly in contact with the centering convex portion 210. The centering convex portion 210 automatically centers and positions the hollow part, and the support roller 200 and the hollow part rotate smoothly.

[0034] In the embodiment, the thickness of the annular plate gradually decreases in the radial outward direction of the supporting roller 200, so as to facilitate matching with the middle groove shape of the hollow part, and facilitate alignment of the middle groove shape of the hollow part with the fixed center convex part 210 during the placement process, so as to facilitate alignment of the segmentation knife 310 with the middle part of the hollow part, and the structure is simple and has a guiding effect. It is conceivable that the annular plate can also be a plate body with uniform thickness in other embodiments, and those skilled in the art can make specific configurations according to actual needs.

[0035] It is conceivable that the centering protrusion 210 may also be other structures. For example, the centering protrusion 210 is a plurality of centering convex teeth arranged around the support roller 200. Those skilled in the art may configure the structure according to actual needs.

[0036] In the embodiment, two supporting rollers 200 are provided, and both supporting rollers 200 are provided with a fixed center convex portion 210, and the two fixed center convex portions 210 are opposite to each other. Two supporting rollers 200 are sufficient to support the hollow part, and both supporting rollers 200 are provided with a fixed center convex portion 210. When the hollow part is placed in the workpiece accommodating position, the fixed center convex portion 210 is more easily aligned with the middle groove of the hollow part, and the hollow part is not easily offset relative to a supporting roller 200 when rotating, so that it is convenient for the segmentation knife 310 to align with the middle part of the hollow part.

[0037] In the embodiment, the segmentation knife 310 is located between the centering convex portions 210 of the two support rollers 200, so that the segmentation knife 310 can cut the hollow part in a more stable position. It is conceivable that the segmentation knife 310 can also be located at other positions, for example, the segmentation knife 310 is located on one side of all the support rollers 200 and the segmentation knife 310 is aligned with the centering convex portion 210.

[0038] In the embodiment, the rotation axes of the two supporting rollers 200 are located in the same horizontal plane, and the outer diameters of the two supporting rollers 200 are the same, so that the two supporting rollers 200 have a relatively balanced supporting effect on the hollow part placed at the workpiece accommodating position, making it difficult for the hollow part to fall over the supporting rollers 200 on either side.

[0039] In an embodiment, the segmentation knife 310 is movably arranged on the machine base 100, and the segmentation mechanism 300 also includes a segmentation driver 320, which is arranged on the machine base 100 and can drive the segmentation knife 310 to move close to or away from the workpiece accommodation position. The segmentation driver 320 is provided, and the segmentation knife 310 can be driven close to or away from the hollow part, providing a physical basis for equipment automation. Specifically, the segmentation driver 320 is a cylinder, and the cylinder is connected to the machine base 100. The piston rod of the cylinder is connected to the segmentation knife 310. The segmentation knife 310 is indirectly arranged on the machine base 100 through the cylinder, so that the segmentation knife 310 can move relative to the machine base 100. It is conceivable that the segmentation knife 310 can also be slidably connected to the machine base 100 through a slide rail slider, and the segmentation knife 310 is driven to move by the segmentation driver 320; the segmentation driver 320 can also be other structures, such as electric cylinders, oil cylinders, etc., which output linear power.

[0040] It is conceivable that in other embodiments, the dividing knife 310 can also be moved closer to or farther away from the workpiece receiving position by other means. For example, the dividing knife 310 is rotatably connected to the machine base 100 and moves closer to or farther away from the workpiece receiving position by swinging. At this time, the dividing driver 320 can adopt a reduction motor, a rotary cylinder or other structures to drive the dividing knife 310 to rotate.

[0041] In an embodiment, the rotary drive mechanism 400 includes a lifting frame 410, a driving roller 420, a rotation driver 430 and a lifting driver 440. The driving roller 420 is rotatably arranged on the lifting frame 410 and the rotation axis is parallel to the rotation axis of the supporting roller 200. The rotation driver 430 is arranged on the lifting frame 410 and can drive the driving roller 420 to rotate. The lifting frame 410 is movably arranged on the machine base 100 in the vertical direction and can make the driving roller 420 approach or move away from the workpiece accommodating position. The lifting driver 440 is connected to the lifting frame 410 and can drive the lifting frame 410 to move. The driving roller 420 is located above the workpiece accommodating position. When the lifting drive 440 causes the lifting frame 410 to drive the driving roller 420 to approach the workpiece receiving position, the driving roller 420 can better clamp and fix the hollow part together with the supporting roller 200, and then the rotating drive 430 causes the driving roller 420 to rotate. The friction of the driving roller 420 drives the hollow part to rotate, and the rotating part drives the supporting roller 200 to rotate, so that the driving roller 420, the hollow part and the supporting roller 200 are all rolling friction. The rotating drive mechanism 400 can not only drive the hollow part to rotate, but also better clamp and position the hollow part together with the supporting roller 200.

[0042] Specifically, the machine base 100 is provided with a slide rail, and the lifting frame 410 is provided with a slider, which is slidably connected to the slide rail, so that the lifting frame 410 can be close to or away from the workpiece accommodation position relative to the machine base 100. It is conceivable that the machine base 100 can also be provided with a guide column, and the lifting frame 410 can be provided with a guide sleeve, and the guide column is inserted into the guide sleeve, so that the lifting frame 410 can be close to or away from the workpiece accommodation position relative to the machine base 100.

[0043] Specifically, the rotation driver 430 is a motor, which drives the driving roller 420 to rotate. It is conceivable that the rotation driver 430 can also be a structure in which an internal combustion engine can output rotational power.

[0044] Specifically, the lifting drive 440 includes a servo motor, a ball screw and a screw nut. The screw nut is connected to the lifting frame 410. The ball screw is arranged vertically. The ball screw and the screw nut are threadedly matched. When the servo motor drives the ball screw to rotate, the lifting frame 410 can be driven to rise and fall through the screw nut.

[0045] It is conceivable that the lifting driver 440 may also be other structures. For example, the lifting driver 440 is a structure that outputs linear power, such as an air cylinder, an oil cylinder, or a linear motor.

[0046] It is conceivable that the rotary drive mechanism 400 can also be other structures. For example, the rotary drive mechanism 400 includes two top clamping blocks and a motor. The two top clamping blocks are pivotally connected to the base 100 and can clamp the two ends of the hollow part. One of the top clamping blocks is connected to the output shaft of the motor to drive the hollow part to rotate.

[0047] In an embodiment, the diameter of the driving roller 420 is larger than the diameter of the supporting roller 200, so as to better clamp the hollow part. It is conceivable that in other embodiments, the diameter of the driving roller 420 may be smaller than the supporting roller 200 or the same as the supporting roller 200.

[0048] Specifically, the driving roller 420 is made of polyurethane.

[0049] In the embodiment, the segmentation knife 310 is movably disposed on the machine base 100 in the vertical direction, and the segmentation knife 310 is located below the workpiece accommodating position, and the segmentation knife 310 is vertically opposite to the driving roller 420. The driving roller 420 presses down the hollow part, so that when the segmentation knife 310 cuts into the workpiece upward, the driving roller 420 provides a counteracting force, so that the workpiece is not likely to shake upward, thereby improving the safety of the flower pot cutting machine when in use.
