Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipe cutting, in particular to a feeding mechanism of a pipe cutting machine. BACKGROUND

[0002] Hydraulic plastic pipes, also known as hydraulic rubber pipes, hydraulic oil pipes and the like, are pipe fittings used in hydraulic systems to transport liquid with certain pressure and temperature. According to materials, the hydraulic plastic pipes can be divided into two categories of rubber materials and rubber-plastic materials. According to production processes, the hydraulic plastic pipes can be divided into steel wire braided rubber pipes, steel wire wound rubber pipes, wire braided rubber pipes and cloth wrapped rubber pipes. In application, the length and pipe opening of the pipes need to be processed according to the application environment. Therefore, many pipe cutting machines, pipe shrinking machines and the like appear on the market. Some of them are integrated to form pipe cutting and shrinking machines.

[0003] Through retrieval, the patent application No. CN 208614038 U discloses a feeding mechanism of a pipe cutting machine. The feeding mechanism comprises two feeding racks arranged at intervals. Each feeding rack is provided with a guide rod for placing a round pipe. One end of the guide rod is inclined downward, and the end is provided with a material taking device for taking the round pipe from the guide rod. The material taking device comprises a material taking seat, a material taking track and a first driver for driving the material taking seat to move back and forth along the material taking track. The material taking seat is hinged with a material taking arm and a second driver for driving the material taking arm to rotate around the hinge. When the round pipe needs to be taken, the second driver drives the material taking arm to rotate towards the guide rod and place below the round pipe. Then, the first driver drives the material taking seat to move a certain distance along the material taking track towards the guide rod, so that the material taking arm is placed directly below the round pipe. At this time, the second driver drives the material taking arm to rotate in the opposite direction to take the round pipe, realizing automatic feeding, improving production efficiency and reducing labor intensity.
