Description

Technical Field

[0001] The utility model relates to the technical field of MPP pipe production, in particular to an angle-adjustable MPP pipe production cutting device. Background Art

[0002] MPP pipe is also called MPP power cable protection pipe. MPP pipe uses modified polypropylene as the main raw material. It has excellent electrical insulation, high temperature resistance, and external pressure resistance. It is widely used in municipal, telecommunications, electricity, gas, tap water, heat and other pipeline projects.

[0003] The patent with publication number CN220348515U discloses a cutting device for MPP power pipes with adjustable cutting angle, including a workbench, a rotating shaft and a stand. A cutting device is provided on the top of one side of the workbench, connecting blocks are provided on both sides of the cutting device, and an electric lifting and retracting rod is fixedly connected to the bottom of the connecting block. One side of the rotating shaft is fixedly connected to the two sides of the cutting device, and the side of the rotating shaft away from the cutting device is fixedly connected to the connecting block. The stand is located at the top of both sides of the workbench, the stand is in an inverted U shape, and the two ends of the bottom are fixedly connected to the top of the workbench; the rotating shaft is provided to facilitate the adjustment of the cutting angle of the cutting device, thereby improving the diversity of the cutting device in cutting the pipe body, and further improving the practicality of this device.

[0004] During the specific use of the above-mentioned prior art, the second motor outputs to the rotating shaft, the rotating shaft drives the cutting device to tilt, and then the first motor outputs to the electric lifting and retracting rod, the electric lifting and retracting rod drives the cutting device located above the pipe body to descend at a uniform speed, so that the cutting device runs to cut the pipe body. However, since the pipe body is clamped and fixed by the first positioning block, the second positioning block and the clamping block, the electric lifting and retracting rod can only drive the cutting device to move vertically downward. When the electric lifting and retracting rod drives the cutting device to descend at a uniform speed, the blade of the cutting device will be squeezed with the surface of the pipe body. The cutting device can only cut the pipe body at the beginning, and then the pipe body and the cutting device are against each other, resulting in the cutting device being unable to continue to move downward. If you want to smoothly cut the pipe body at an inclined angle, the cutting device needs to move obliquely to achieve inclined cutting. Therefore, the above-mentioned prior art cannot achieve inclined cutting of the pipe body in actual use. In view of this, we propose an angle-adjustable MPP pipe production cutting device.
