Description
Technical field
The utility model relates to the printing equipment technical field, especially a kind of electromagnetic heater for the film extruder barrel.
Background technology
Current, along with the high speed development of national economy, electric power is as a kind of cleaning, secondary energy sources easily, disparities between supply and demand day is becoming tight, simultaneously, along with increasingly sharpening of inter-industry competition, the control of strengthening manufacturing cost is the important means that enterprise improves profit, dominates the market.In every cost, electric energy is a prime cost, and all there is the situation of " low load with strong power " in most consumer, and the very large energy saving space is arranged, and reduces costs by economize on electricity, improves profit margin imperative.
At present, use the film extruder at packing and plastic products, its barrel is all generally to adopt the Resistant heating circle, resistance wire heating after energising, and the mode by thermal energy conduction makes the machine barrel heating, thereby reaches the purpose that adds thermal material.The advantage of this mode of heating is simple in structure, low price, and shortcoming is that heat energy distributes in a large number, causes the heat temperature raising time long, has not only reduced the efficiency of heating surface, has increased energy consumption, and has dwindled the range of work of plasticizing, has worsened working environment.This mode of heating efficient is lower, the effective rate of utilization of electric energy is often lower than 40%, and heat energy dissipation in air, causes a large amount of waste of energy on the one hand greatly, also make simultaneously the environment temperature in workshop increase, and the long-time use of resistance wire also can reduce service life because of oxidation.
Electromagnetic induction heating is a kind of ripe heating technique, and it is high with thermal effect, heating is fast, power and energy saving, the plurality of advantages such as safe and reliable play an important role in our daily life, as electromagnetic oven etc.Because plant equipment has higher instructions for use to heating system, the reason such as abominable in high-power, long-time heating, environment for use, so that electromagnetic induction heating technology uses lessly on plant equipment, and especially the barrel heating at the film extruder is difficult to realize.
The utility model content
The purpose of this utility model is the electromagnetic heater of a kind of film extruder barrel of designing for the deficiencies in the prior art, barrel adopts the Electromagnetic Heating structure, the high-frequency alternating magnetic field that barrel is responded to converts the high-frequency alternating electric current to directly makes the interior material of barrel directly heat, and thermal effect is high, heating is fast, power and energy saving, safe and reliable.
The purpose of this utility model is achieved in that a kind of electromagnetic heater of film extruder barrel, be characterized in that machine barrel that film is extruded is provided with several and the electromagnetic generator electromagnetic induction heating circle of corresponding setting one by one, several electromagnetic induction heating snares are contained on machine barrel, fill heat preserving and insulating material therebetween, electromagnetic induction heating circle and electromagnetic generator are for being electrically connected; Described several electromagnetic generators are electrically connected electrical power control cabinet.
Described machine barrel is provided with the temperature monitor that is electrically connected with instrument or PC, and instrument or PC and electrical power control cabinet are electrically connected.
The utility model has compared with prior art that firing rate is fast, and heating efficiency is high, and is simple in structure, safe and reliable, long service life, and intelligent control, energy-saving effect is remarkable, has extraordinary application prospect.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
Consult accompanying drawing 1, the utility model is comprised of electromagnetic generator 3, electrical power control cabinet 4, temperature monitor 6 and several electromagnetic induction heating circles 2 of being arranged on machine barrel 1, and several electromagnetic induction heating circles 2 are sleeved on machine barrel 1, fill heat preserving and insulating material therebetween; Described electromagnetic generator 3 is several and electromagnetic induction heating circle 2 corresponding and electric connection one by one; Described several electromagnetic generators 3 are electrically connected electrical power control cabinet 4; Described machine barrel 1 is provided with the temperature monitor 6 that is electrically connected with instrument or PC 5, and instrument or PC 5 are electrically connected with electrical power control cabinet 4, and temperature monitor 6 is fixedly connected with machine barrel 1 outer wall.
the utility model is like this work: electrical power control cabinet 4 with the 220V AC power of access through rectification, filtering accesses electromagnetic generator 3 after becoming direct current, electromagnetic generator 3 accesses electromagnetic induction heating circle 2 direct current is modulated the high-frequency alternating electric current that is reverse into 20 ~ 30kHz through the pulse wide cut after, the high-frequency alternating electric current converts high-frequency alternating magnetic field to by the coil of electromagnetic induction heating circle 2, this high-frequency alternating magnetic field produces powerful eddy current and makes machine barrel 1 self-heating on machine barrel 1, the interior material of machine barrel 1 is heated up to be heated, because machine barrel 1 outer wrap heat-insulating heat-preserving material, all heats are kept at all almost that machine barrel 1 is interior to be heated material, temperature monitor 6 is with the temperature of charge input instrument or the PC 5 that detect, temperature by instrument or 5 pairs of these detections of PC shows, analyze and export control signals to electrical power control cabinet 4, electrical power control cabinet 4 carries out temperature according to control signal by 3 pairs of machine barrels of electromagnetic generator 1 and controls.
The utility model heat energy is preserved fully and is utilized, greatly reduce environment temperature, energy-saving effect is (30%～70%) significantly, can be widely used in plastics machinery, food machinery, heating crude oil conveying, chemical machinery and other heating industries, has application prospect very widely.
More than just the utility model being further described, is not to limit this patent, and all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
