Abstract

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.

Description

technical field

[0001] The invention relates to plastic extrusion processing extrusion die mouth and die outlet surface treatment equipment in wire and cable production, in particular to an auxiliary open flame heating device for plastic extrusion processing surface quality. Background technique

[0002] In the wire and cable manufacturing process, the plastic is heated and melted step by step by an extruder, pushed by a rotating screw, and extruded outside the cable core through a molding die. The heating method of the extruder is to use electric heating tiles, but the heating tiles cannot be installed at the molding die, and can only be heated indirectly by the heating tiles at the machine head through metal conduction. Therefore, the temperature of the molding die, which is a key device that restricts the quality of the plastic extrusion surface, cannot be adjusted and changed by itself. In order to achieve the best molding and plasticizing temperature of the plastic at ...
