Description
Technical field
The utility model relates to the plastic machine technical field, is specifically related to a kind of energy-saving electromagnetic and adds the thermoplastic blow moulding machine.
Background technology
At present; In the plastic cement commercial production, need extensively use electrical heating; And 90 percent above what use is the resistance wire mode of heating, and this mode of heating mainly is to be abutted against to touch conduction and come transferring heat energy; With various heating plates, the circle that resistance wire is processed, the heat that only abuts against the barrel inner side surface just can pass on the barrel.
There is following shortcoming in this traditional heater:
(1) heat loss is big: the mode of heating that existing enterprise adopts is by the resistance wire coiling, two-sided heating inside and outside the circle, and the heat of its inner face (being close to the barrel part) is transmitted on the barrel, and the heat major part of outside is lost in the air, causes the loss and waste of electric energy.
(2) environment temperature rises: because heat scatters and disappears in a large number; Ambient temperature is very big to the production environment influence in rising, especially summer, and the work on the spot temperature has all surpassed 45 ℃; Some enterprise has to adopt air-conditioning to reduce temperature, and this causes the secondary waste of the energy again.
(3) service life is short, maintenance capacity is big: owing to adopt the resistance wire heating, its heating-up temperature up to 800 ℃ about, resistance wire blows because of high temperature ageing easily, therefore, the workload of maintenance is relatively large about about half a year service life for electric heating coil commonly used.
In addition the conventional point heater also has the slow characteristics that heat up, and causes inefficiency, and the resistance wire heating to also have a shortcoming be exactly that power density is low, need the higher heating occasion of temperature just can't adapt at some.
The utility model content
The utility model technical problem to be solved is to provide the electromagnetism of characteristics such as a kind of efficient, energy-conservation to add the thermoplastic blow moulding machine.
The utility model technical problem to be solved adopts following technical scheme to realize.
A kind of energy-saving electromagnetic adds the thermoplastic blow moulding machine; Comprise frame and be located at the barrel on the frame, said barrel one end is provided with feed hopper, and the barrel other end is provided with extrusion die; Said barrel inside is provided with extrusion screw rod; Said extrusion screw rod end is connected with transmission mechanism, it is characterized in that: said barrel circumference is provided with electromagnetic heater, and described electromagnetic heater is electrically connected with the electromagnetic heater switch board.
Described electromagnetic heater comprises shell and is wrapped in the high frequency coil of enclosure.
Described barrel surface is provided with heat-insulation layer.
Described heat-insulation layer is the pearl cotton material.
Described high frequency coil adopts insulating materials and high-temperature cable manufacturing to form.
The utility model is that a kind of electromagnetic heater that utilizes electromagnetic induction principle to process converts electrical energy into heat energy; Utilize high frequency electric source to switch on to electromagnetic heater; The high frequency coil that the electric current that changes at a high speed flows through electromagnetic heater can produce the magnetic field that changes at a high speed; The magnetic line of force in magnetic field is through barrel and extrusion screw rod, and the huge eddy current of the inner generation of barrel and extrusion screw rod makes barrel and extrusion screw rod heating at a high speed voluntarily itself.
The utility model has following beneficial effect to be:
(1) good energy-conserving effect is compared former resistance wire heating collar power savings all more than 30%.
(2) environment protecting is good, can significantly reduce indoor operating ambient temperature.
(3) long service life, the continuous running temperature of heating collar has only about 100 ℃, and the problem that does not exist heating collar to change has reduced the secondary input with respect to former resistance wire heating.
(4) can improve product yield,, can significantly reduce the heating-up time, improve product yield because the heating efficiency of this device is high.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of energy-saving electromagnetic adds the thermoplastic blow moulding machine, comprises frame 1 and is located at the barrel 3 on the frame 1; Barrel 3 one ends are provided with feed hopper 7, and barrel 3 other ends are provided with extrusion die 6, and barrel 3 inside are provided with extrusion screw rod 2; Extrusion screw rod 2 ends are connected with transmission mechanism, and barrel 3 circumference are provided with electromagnetic heater 5, and electromagnetic heater 5 is electrically connected with the electromagnetic heater switch board; Electromagnetic heater 5 comprises shell and is wrapped in the high frequency coil of enclosure; Barrel 3 surfaces are provided with heat-insulation layer 4, and heat-insulation layer 4 is the pearl cotton material, and high frequency coil adopts insulating materials and high-temperature cable manufacturing to form.
The utility model is that a kind of electromagnetic heater 5 that utilizes electromagnetic induction principle to process converts electrical energy into heat energy; Utilize high frequency electric source to give electromagnetic heater 5 energisings; The high frequency coil that the electric current that changes at a high speed flows through electromagnetic heater 5 can produce the magnetic field that changes at a high speed; The magnetic line of force in magnetic field is through barrel 3 and extrusion screw rod 2, and barrel 3 and the huge eddy current of extrusion screw rod 2 inner generations itself generate heat barrel 3 and extrusion screw rod 2 voluntarily at a high speed.
Energy-saving electromagnetic adds in the process of thermoplastic blow moulding machine work; Granular plastic raw materials gets into barrel 3 from feed hopper 7; Extrusion screw rod 2 rotations are sent raw material to barrel 3 inside; Barrel 3 melts plastic grain with the high temperature that the magnetic field that the high speed that extrusion screw rod 2 produces at electromagnetic heater 5 changes produces down, and the plastics that under the drive of extrusion screw rod 2, melted are from extrusion die 6 ejaculations of barrel 3.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
