The invention discloses an auxiliary open fire heating device for improving the surface quality of extruded plastics. The auxiliary open fire heating device comprises a bracket base device and a fire jetting combustion furnace tray device and is characterized in that the bracket base device comprises a base and a support frame, and the support frame is mounted on the base; the fire jetting combustion furnace tray device comprises a gas inlet valve, a gas guide pipe and nozzle devices; the gas inlet valve is mounted at an inlet of the gas guide pipe; the nozzle devices are mounted on the gas guide pipe; and the fire jetting combustion furnace tray device is mounted on the bracket base device through the support frame. The auxiliary open fire heating device has the advantages of simplicity, convenience and feasibility and also has the advantages of being convenient to use, high in efficiency, high in practicability, light in structure and convenient to mount, disassemble and operate. Generally, when large-molecular-weight plastics of a molecular chain net structure, such as organosilane crosslinked polyethylene, are processed and produced, the auxiliary open fire heating device is directly mounted on a nose of the existing extruder by using magnetic absorption and utilizes open fire to carry out auxiliary open fire heating on a forming die orifice and an extruded wire so as to improve the poor surface quality of the extruded product.

The invention discloses a polyethylene plastic submerged material impurity removing system. The polyethylene plastic submerged material impurity removing system structurally comprises a main control computer, supporting legs, a supporting filter layer and an imbedding opening, wherein the main control computer is connected with a main control wheel through a wire, the supporting legs are welded tothe lower surface of the supporting filter layer, objects are extruded into an adhesive supporting head, can be adhered by an adhesive head at first, the extrusion force stacked at the rear end enables the objects to be continuously extruded, the rear end of the object is buffered and dragged by an adhesive tape, and is changed according to the moving direction of an object, so that the object can be smoothly extruded into the interior through adhesion of the adhesive supporting head, the surface of the object can be adsorbed when the object is guided into machining equipment, batting of theobject can be separated, water is placed in the interior, the residual batting can be separated from the object through impulsive force of the water and can smoothly slide into bag grids to be placedso that the foreign object can smoothly slide, the rear end of a position expanding strip is uniformly stressed by uniform force balls, the batting further left on the surface of the object and is separated through the water when the submerged material is separated, and the batting can be intercepted for storage.
