Abstract

The invention relates to the field of production of plastics, in particular to a PVC (polyvinyl chloride) pipe chipless cutting mechanism in combined transmission of gears, a turntable and a bearing. The PVC pipe chipless cutting mechanism comprises the turntable, a motor, a driving gear and a cutting unit. The cutting unit consists of roller dovetail mounting plates, a roller bearing frame, a clamping wheel component, a bearing frame mounting plate, an input shaft gear, a cutter component, a blade bearing frame and a cutting feed lead screw, a fixed gear is meshed with the input shaft gear, the input shaft gear is connected with the cutting feed lead screw, the cutting feed lead screw is arranged vertically, the bearing frame mounting plate is horizontally fixedly arranged at the lower end of the cutting feed lead screw, the blade bearing frame is disposed on one side of the bearing frame mounting plate, the roller bearing frame is arranged on the other side of the bearing frame mounting plate, both the blade bearing frame and the roller bearing frame are provided with sliding plate grooves, and each sliding plate groove consists of an oblique groove section and a straight groove section which are communicated with each other. The cutting mechanism is simple in structure, can realize rolling depression for an arched flash at a joint-cutting position while cutting, and guarantees the quality of notches.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a chipless cutting mechanism and a cutting machine for a PVC pipe with a combined transmission of a gear turntable bearing. Background technique [0002] At present, domestic and foreign chipless cutting machines are usually used for cutting plastic polyethylene (PE) and tripropylene polyethylene (PPR) pipes. Polyvinylchloride (PVC) pipes are usually cut by saw blades. Cutting produces a lot of dust during the cutting process, which is difficult to collect and poses a hazard to the environment and the health of on-site operators. The traditional chipless cutting transmission mode: first, the rotation of the turntable installed with the cutting feed mechanism is completed by the motor driving the belt pulley, and the cutting feed depth (the maximum thickness of the cutting pipe diameter) is driven by the cylinder with damping function and installed on the pulley , Sliding plate ...
