Abstract

The invention relates to the technical field of extruding machines, in particular to a high-efficiency and stable full-automatic plunger type PTFE strip extruder. The high-efficiency and stable full-automatic plunger type PTFE strip extruder comprises a rack, a material bin, an automatic weighing and feeding mechanism, a pre-pressing and blank-forming device and a long-strip extruding mechanism, wherein the pre-pressing and blank-forming device comprises a circulation conveying mechanism, a material injecting cylinder and a pre-pressing driving system; the high-efficiency and stable full-automatic plunger type PTFE strip extruder further comprises a first detection element arranged at the pre-pressing and blank-forming device and a second detection element arranged at the long-strip extrusion mechanism; and the high-efficiency and stable full-automatic plunger type PTFE strip extruder further comprises a controller which saves manpower consumption, reduces the influence of manual operation on the PTFE fiber finished product, improves the quality of the PTFE long fiber product, is small in occupied area and simple to operate, achieves integration, greatly improves the production efficiency, greatly improves the stability, and greatly improves the production processing efficiency.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to an efficient and stable full-automatic plunger type PTFE strip extruder. Background technique [0002] Polytetrafluoroethylene (PTFE) fiber is a very difficult to process organic special fiber, which has excellent high and low temperature resistance, chemical stability, good electrical insulation, non-adhesion, weather resistance, flame retardancy and Good self-lubricating property is an indispensable important material to solve many key technologies in the fields of scientific research, military industry and civil use and to improve the level of production technology. At present, PTFE fiber is widely used in chemical industry, petroleum, textile, medical treatment, machinery and other fields. In addition, it is also the preferred material for waste incineration space suits, fire protection suits, filter materials and aerospace materials. [0003] In recent years, my country's...
