Abstract

The invention discloses a PEEK plastic rod production device and process. The PEEK plastic rod production device comprises a main machine and an auxiliary machine. The main machine is an extruder and comprises an extruding system, a rotating system and a control system, wherein the extruding system is a gun barrel screw; the rotating system comprises a motor and a reduction box; the control system comprises an electric appliance instrument and an actuating mechanism; the auxiliary machine comprises a mold, a traction machine, an oil temperature machine, a cutting machine and an oven; the mold comprises a main mold, a guide plate, a heat insulation ring, a forming shaping barrel and a cooling water tank; the oil temperature machine is installed on a shaping section of a forming pipe; the traction machine mainly comprises a transmission device, a roller compression device and a brake device, and is installed behind a heat preserving device; the cutting machine is installed behind an outlet of the mold; the oven is a closed box body. The process comprises the steps of charging, drying, plasticizing extruding, homogenizing distributing, forming/shaping, pulling, cutting/stacking and thermal processing.

Description

technical field [0001] The invention discloses a PEEK plastic rod production equipment and process. Background technique [0002] PEEK rod extrusion molding is to add granular materials into the barrel of the extruder from the hopper, and the materials are conveyed forward and compacted by the friction between the inner wall of the barrel and the surface of the screw under the extrusion force of the screw rotation. The heating device and friction preheating on the outside of the barrel melt and plasticize under high temperature and high pressure conditions. Then, the continuously rotating screw pushes the molten material into the mold of the die, and the molten material extruded from the die is cooled and shaped into the required PEEK product. [0003] The previous production equipment and process are as follows: [0004] PEEK Rod Extrusion Line figure 1 As shown, the composition of the PEEK rod extruder molding production line: [0005] The production line of PEEK rod e...
