[0043] Compared with the prior art, the beneficial effects of the present invention are as follows: The length of the cut plastic water pipe is inspected initially to determine if its length is acceptable. If the length is too long, the conveyor belt speed is increased. If the length is slightly long, the roughness of the cut edge of the plastic water pipe is inspected to further determine whether the quality of the cut water pipe meets the preset standard. Furthermore, if the cut edge is determined to be too rough, the descent speed of the cutter is increased to avoid the cutter failing to quickly and vertically cut the water pipe due to a slow descent speed, resulting in an uneven cut edge. If the cut edge is determined to be relatively rough, it is determined that insufficient cutter pressure prevents a complete and smooth cut of the plastic water pipe. Therefore, the pressure of the hydraulic press is increased to ensure a smooth cut edge and that the cutting length meets the standard, thereby further improving the cutting quality of the plastic water pipe.

[0044] Furthermore, when the determination module determines that the operating parameters of the cutting module meet the preset standards, the perimeter of the cutting opening is obtained to further determine whether the cutting opening of the plastic water pipe cut by the cutter is simultaneously perpendicular to the receiving platform and the water pipe. In order to reduce the transmission speed of the conveyor belt when the cutting opening of the plastic water pipe is uneven, so as to facilitate the positioning and cutting of the cutter, thereby improving the cutting quality of the plastic water pipe.

[0045] Furthermore, when the determination module determines that the operating parameters of the cutting module do not meet the preset standards a certain number of times, it determines that the poor cutting effect is caused by the cutter not meeting the preset standards. The cutter is then inspected and replaced in a timely manner, which further improves the cutting quality of plastic water pipe cutting.

[0046] Furthermore, when it is determined that the descent speed of the adjusted hydraulic press is greater than the preset maximum speed, the transmission speed of the conveyor belt is reduced to coordinate the transmission speed of the conveyor belt with the descent speed of the cutter, so as to further improve the cutting quality of the plastic water pipe.
