Abstract
The invention provides a heating component for a plastic extruding machine and belongs to the technical field of plastic extruding machines. The heating component comprises at least three heating devices installed outside a charging barrel in a sleeving ode and a shell installed outside the heating devices in a sleeving mode to protect the heating devices, wherein the heating devices are infrared heating devices or electromagnetic heating devices. The heating component is simple in structure, convenient to install, and capable of being used in cooperation with a charging barrel of the plastic extruding machine and a screw extruder quickly. Due to the fact that the infrared or electromagnetic heating devices are adopted to replace original resistance wires for heating, heating efficiency is improved, and energy waste is reduced.
Description
Technical field
The present invention relates to extruding machine technical field, particularly relate to a kind of extruding machine heating component.
Background technology
During extruding machine work, utilize the screw rod of given shape, rotate in the machine barrel of heating, extrude by the plastic master batch sent here in hopper forward, plastic master batch is plastified (i.e. melting) equably, by head and difform mould, plastic matrix is made to be squeezed into the successional required plastic layer of various shape or the product of other shapes.Existing extruding machine adopts screw technique, and heater is arranged on outside barrel, and existing heater mostly is Resistant heating, and Resistant heating efficiency is low on the one hand, and power consumption is large, adds production cost; On the other hand, during Resistant heating, barrel is heated uneven, affects the melting of plastic master batch, affects the quality of final products.
Summary of the invention
The problem to be solved in the present invention is that the heating of existing extruding machine adopts Resistant heating, and barrel is heated uneven, and the efficiency of heating surface is lower.
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of extruding machine heating component, comprises and is sleeved at least three group heaters outside barrel and is sleeved on the shell that heater protected outward by heater.
Described heater is infrared heating device or electromagnetic heater.
Preferably, described heater is evenly distributed along the axis of barrel.
Described screw rod has auxiliary heating passage; Described auxiliary heating passage is U-shaped, and the axisymmetrical along screw rod is arranged on screw rod; An end face of screw rod has the inlet and liquid outlet that are connected with auxiliary heating passage.
Described liquid outlet and inlet are equipped with valve, and described auxiliary heating passage is connected with the circulating pump storing heating liquid with liquid outlet by inlet.
Heat-insulation layer is set with between described shell and heater.
The material of described heat-insulation layer is rock wool or Polystyrene heat insulation material.
Also comprise the base of supporting outer, described base is arranged on the below of shell, removably connects with shell.
The cooling system of cooled enclosure and screw rod is provided with in described base.
The advantage that the present invention has and good effect are: structure of the present invention is simple, arrange conveniently, can support the use with the barrel of extruding machine and screw extrusion apparatus quickly, adopt infrared or electromagnetic heater, replace original Resistant heating, improve the efficiency of heating surface, decrease the waste of the energy.Be provided with at least three group heaters in the present invention, heat respectively the different phase of Screw Extrusion, the temperature needed for different material melting and the process of deformation can arrange different heating temperature range, further ensure the carrying out that raw materials melt is extruded.On screw rod, be also provided with auxiliary heating passage in the present invention, heating liquid flows in auxiliary heating passage, heats screw rod itself, prevents the excessive temperature differentials between screw rod and fused raw material, affects extruding of raw material.
