Abstract

The invention discloses a special granulation extruder for FEP powder materials. An extruder body is included; a storage hopper is fixedly installed on the top of one side of the extruder body; the bottom of the storage hopper is connected with a guide-out pipe; the guide-out pipe is located in the extruder body; a spiral conveying shaft is rotationally installed in the extruder body; a verticallyarranged linkage pushing rod is welded to the outer wall of one side of the spiral conveying shaft; a movable sealing plate corresponding to the linkage pushing rod is further arranged at the bottomof the guide-out pipe; one side of the movable sealing plate is provided with a discharging port; one end of the movable sealing plate is connected with a sliding plate perpendicular to the movable sealing plate; the two sides of the sliding plate are each connected with a supporting sliding rod in a sliding manner; each supporting sliding rod is provided with a spring; and a movable sliding rod matched with the linkage pushing rod is welded to the bottom of the other side of the movable sealing plate. According to the special granulation extruder for the FEP powder materials, design and arrangement are reasonable, the purpose that material conveying and quantitative feeding are performed at the same time is achieved, cost is low, and the machining quality of the extruder is improved.

Description

technical field [0001] The invention relates to the technical field of FEP powder processing, in particular to a special granulation extruder for FEP powder. Background technique [0002] The full name of FEP is Fluorinated ethylene propylene, translated as fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer) English trade name: Teflon*FEP, is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. FEP can be applied to soft plastics, and its tensile strength, abrasion resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide temperature and frequency range. Existing granulation extruders for FEP powder processing are simple in structure and relatively single in performance, making it difficult to achieve the purpose of quantitative feeding. It usually performs one-time feeding of required materials during material pro...
