Description

Electromagnetism hot-air heating type EPE heat-sealing machines

Technical field

A kind of heat-sealing machine is the utility model is related to, particularly a kind of electromagnetism hot-air heating type EPE heat-sealing machines.

Background technology

In EPE (polyethylene foams) process of producing product, it is often necessary to by heat-sealing machine by relatively thin EPE materials After high-temperature heating, local hot melt, then by extruding the certain thickness EPE products of thermal synthesis.In the prior art, in heat-sealing machine On generally have to the heating means of EPE materials following two, one kind is heated by heat radiation caused by fuel gas buring, another It is to lean on heat radiation caused by resistance wire to heat.But existed by the way of fuel gas buring and heat uneven, dangerous, environment The problem of pollution；Heated using heat radiation caused by resistance wire, there is that heat is not concentrated, thermo-lag is larger, is not easy accurately to control The problem of warm, and because the heat of resistance wire largely scatters and disappears in atmosphere, heat loss is big, so high energy consumption, can also be caused Environment temperature raises, and operating environment is become severe, on the other hand because the service life of resistance wire is short, so changing, maintenance Workload is also very big.

Utility model content

The problem of for background technology, the utility model provide a kind of electromagnetism hot-air heating type EPE heat-sealing machines, the heat-sealing machine Solve the problems, such as heat-sealing machine mode of heating temperature control of the prior art it is inaccurate, using it is dangerous, do not save, short life, together When can also improve working environment.

The purpose of this utility model realizes that it includes by such technical scheme：

A kind of electromagnetism hot-air heating type EPE heat-sealing machines, including 2 pressure rollers, the axially in parallel neighbouring setting of 2 pressure rollers, 2 pressures Gap between roller forms heat seal portion, it is characterised in that：More electromagnetism storage heaters are provided with below the heat seal portion；Institute Stating electromagnetism storage heater includes flow-guiding mouth, heating part, air pump and heating controller；The heating part by tubular sheath, more Steel pipe, coil and heat-insulation layer composition；The steel pipe is arranged in the inner chamber of tubular sheath, the axial direction of steel pipe and the axle of tubular sheath To parallel to each other；The heat-insulation layer is wrapped in the peripheral outer wall of tubular sheath, and the coil is wrapped in the week of heat-insulation layer outwards On wall；One end of the tubular sheath connects with the inlet end of flow-guiding mouth, and the other end of tubular sheath and the output end of air pump connect It is logical；The coil is connected with heating controller；The outlet side of the flow-guiding mouth is strip shape gob, axial direction and the heat seal portion of strip shape gob Axially in parallel, outgassing direction and the heat seal portion of strip shape gob align, and the outlet side of multiple flow-guiding mouths axially arranges along heat seal portion.

Electromagnetism storage heater in the utility model is a kind of to convert electrical energy into heat energy using electromagnetic induction principle Device, by heating controller by AC rectification into direct current, then direct current changed into high-frequency high-voltage current, work as high-frequency and high-voltage When electric current flows through the coil being wrapped in outside tubular sheath, the alternating magnetic field that the steel pipe in sheath produces change at a high speed forms vortex, The vortex makes the iron atom high speed random motion of steel pipe, and iron atom collides with each other, rubbed and produces heat energy.When caused by air pump When gas with certain pressure is by steel pipe in tubular sheath, the energy heats caused by steel pipe, become hot blast, the hot blast Blown out by the strip shape gob of flow-guiding mouth, on integrated distribution to heat seal portion, the material in heat seal portion is heated, treated by pressure roller The material of bonding is extruded so as to realize the heat seal to material.

By adopting the above-described technical solution, the utility model has the following advantages：Because coil substantially will not in itself Heat is produced, carrys out hot gas mainly by the steel pipe heating inside tubular sheath, plus being additionally provided with insulation on sheath outer peripheral face Layer, heat concentrated on inside tubular sheath, substantially without lost, and hot blast is applied into heat to concentrate by the strip shape gob of flow-guiding mouth The axial range in conjunction portion, Btu utilization is abundant, thus saves the energy；Because coil does not generate heat in itself, the stagnant small, thermal inertia of thermal resistance Low, temperature control is accurate in real time；And coil surface temperature is only slightly higher than room temperature, can with safe touch, without high temperature protection, Securely and reliably, the rise of environment temperature while will not be also caused, substantially improves the working environment of production scene；Magnet coil sheet Body does not produce heat, service life length, reduces replacing, maintenance cost.
