PVC pipe cutting mechanism

Abstract

The invention provides a PVC pipe cutting mechanism which comprises a first rotating disc, a first rotating shaft, a rotation driving mechanism, a swing arm, a second rotating shaft, a first rotation synchronizing wheel, a saw blade synchronizing wheel, a saw blade synchronizing part, a saw blade, a second rotating disc, a fixing part, a feeding driving mechanism and a revolution driving mechanism, wherein the first rotating shaft is pivotally arranged on the first rotating disc in a penetrating manner; the autorotation driving mechanism is connected with the first rotating shaft; one end of the swing arm is rotatably arranged on the first rotating shaft in a sleeving manner, the second rotating shaft is rotatably arranged at the other end of the swing arm in a penetrating manner, and the first autorotation synchronizing wheel is arranged on the first rotating shaft; the saw blade synchronizing wheel is arranged on the second rotating shaft, the saw blade synchronizing part is wound on the first autorotation synchronizing wheel and the saw blade synchronizing wheel, and the saw blade is connected with the second rotating shaft; the fixing part is fixedly connected between the first rotating disc and the second rotating disc; the feeding driving mechanism is connected with the swing arm and can drive the swing arm to swing around the first rotating shaft. The revolution driving mechanism is connected with the first rotating disc and can drive the first rotating disc to rotate.

Description

technical field [0001] The invention relates to the technical field of pipe extrusion production, in particular to a PVC pipe cutting mechanism. Background technique [0002] The PVC pipe cutting machine is used in the PVC pipe extrusion line to cut the extruded pipe to the set length. Due to the physical characteristics of PVC pipes, it is generally necessary to cut them with a saw blade. When the diameter of the PVC pipe is large, the cutting arm and the motor that drive the saw blade to rotate need to revolve around the pipe during the cutting process. Since the cable powered by the motor cannot always follow the revolution, it is generally used here. Electric slip rings are used to power the saw blade motor and a hydraulic power unit is used to provide the feed movement of the cutting arm. And the prior art solutions for cutting PVC pipes on the market, because the structural layout takes up a lot of space, the cutting box is very heavy. Moreover, during use, due to s...
