Abstract
The utility model discloses a direct heating equipment for drawing dies for plastic flat fiber drawing processing, which comprises the drawing dies connected with the material injecting tee of a plastic extruding machine, a thermal-insulating material layer (8) covered and wrapped on the shell body of the drawing dies (6), and induction coils (9) electrically connected with a converter SB phase. By the direct heating character of the utility model using magnetic energy for energy conversion, the utility model can make the conversion efficiency of electricity and heat energy reach to 90% to shorten the preheat time of the drawing die bodies. The peripherical temperature of a heating device can be reduced to 80 DEG by arranging the thermal-insulating material layer. Compared with prior art, the utility model can save electricity up to more than 40% for reducing the temperature of manufacturing shops and improving the manufacturing environment of workers obviously.
Description
Affiliated technical field
The utility model relates to a kind of plastic flat fiber Wire Drawing device, relates to a kind of direct heater that is used for plastic flat fiber Wire Drawing membrane mould specifically.
Background technology
In existing plastic flat fiber wire-drawing processing method, its production and processing device unit front end is formed by extruder.Figure 1 shows that the extruder of existing general plastic flat filament Wire Drawing device unit front end, it comprises control unit 1, hopper 2, and barrel 3, material feeding threeway (threeway) 4 and membrane mould (claiming die head again) 6 five parts are formed.Its operation principle is that raw material is in hopper 2 enters barrel 3 cavitys, enter material feeding threeway 4 through flat filament wire drawing screw rod, impurities in raw materials is removed in insulation and filtration through material feeding threeway 4, flow into membrane mould 6, membrane mould 6 carries out the adjustment and the control of width and thickness with the raw material of molten state, and the water cooling of raw material in tank 7 that flows out membrane mould 6 forms the required film of subsequent production.The weak point of above-mentioned existing extrusion device is that 5 heating realize by conduction pattern membrane mould 6 required holding temperatures by the resistance wire heat block.According to hot propagation formula, the temperature difference is big more, and hot-fluid is big more, and area is big more, hot-fluid is big more, because temperature difference is bigger between existing resistance type heater and membrane mould, the peripheral temperature of heater reaches about 600 ℃, and its heat energy is bigger at the space volatile quantity, the direct result that causes is that the thermal efficiency is low, it is long to start heat time heating time, and power consumption is high, is difficult to reduce production costs.
Summary of the invention
The purpose of this utility model provides a kind of thermal efficiency height, and energy-saving effect significantly is used for the direct heater of plastic flat fiber Wire Drawing.
Of the present utility model can the realization by the following technical solutions: it comprises the membrane mould that links to each other with material feeding threeway on the plastic extruder, parcel, the induction coil that is wound with the insulation insulation material layer and is electrically connected with frequency converter SB on the membrane mould housing.
Described insulation insulation material layer directly wraps up on the membrane mould housing, and the induction coil that is electrically connected with frequency converter SB is wrapped in outside the insulation insulation material layer.
Above-mentioned induction coil also can be arranged between membrane mould housing and the insulation insulation material layer.
Principle of the present utility model is that power frequency supply is converted to AC power about single-phase 50KHZ through converter plant, flow to induction coil, produce magnetic field, make electronics and atom high velocity impact in the housing metal material produce the heat shock energy, adopt magnetic energy to carry out energy conversion, the membrane mould housing is directly generated heat, and utilize the adiabator layer that is wrapped on the housing, prevent heat-energy losses membrane mould housing insulation.
Direct heating of the present utility model (adopting magnetic energy to carry out power conversion) feature can make electricity, heat energy conversion efficient reach more than 90%, makes shortening preheating time of membrane mould housing.Be incubated the setting of insulation material layer, the peripheral temperature of heater is reduced to about 80 ℃ in addition.The utility model compared to existing technology, its power saving rate can reach more than 40%, and the temperature of workshop is minimized, and workman's production environment is significantly improved.
