Description
Technical field
The utility model relates to the electromagnetic heater technical field, relates in particular to a kind of plastic machine electromagnetic heater.
Background technology
Plastic machine on the present stage market adopts the resistance-type heating collar mostly, and the mode by the contact conduction passes to heat on the barrel, has only the heat of close barrel inboard to be absorbed and used, and the most of loss of the heat in the outside.Along with improving constantly of electromagnetic heating technique, the electromagnetism heating is applied to the heating part of plastic machine gradually.But the plastic machine barrel adopts manual mode parcel thermal insulation material to be used for insulation, the bad grasp of thickness mostly at present, cause the plastic machine barrel uneven like this, when the winding electromagnetic heating coil is installed, add thermal effect for reaching best electromagnetism, the specification requirement height, and, when handling different materials such as rubber or plastics, need different temperature, when from high-temperature to the low temperature process, because plastic machine barrel outer wall is made by insulation material, heat radiation slowly needs long time.
The utility model content
The technical problem that the utility model solves is twined that the electromagnetic heating coil difficulty is little, the electromagnetism heating is effective, is needed short plastic machine electromagnetic heater of time during cooling with regard to providing a kind of the installation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the insulated coil that is positioned at the plastic machine barrel outside, be with the coil brace that surrounds vacuum cavity by insulation inwall and insulation outer wall in the described plastic machine barrel outside, described coil brace is fixed by the bracing frame and the plastic machine barrel that are positioned at the axial both ends of coil brace, and described insulated coil is wrapped in described insulation outer exterior wall.
Its additional technical feature is:
Surround the wind chamber between the described plastic machine barrel outside and the insulation inwall;
Be positioned at position, wind chamber at described bracing frame and be provided with plurality of air;
Be provided with air blast in described bracing frame one side;
Described insulation outer exterior wall face is the face of cylinder;
Described insulation outer exterior wall face is provided with groove;
Described coil brace is formed at least two sub-coil supports that surround the annulus tube mutually, and each sub-coil support is provided with vacuum separately and divides cavity.
Plastic machine provided by the utility model with electromagnetic heater compared with prior art, have the following advantages: one, owing to comprise the insulated coil that is positioned at the plastic machine barrel outside, be with the coil brace that surrounds vacuum cavity by insulation inwall and insulation outer wall in the described plastic machine barrel outside, described coil brace is fixed by the bracing frame and the plastic machine barrel that are positioned at the axial both ends of coil brace, described insulated coil is wrapped in described insulation outer exterior wall, vacuum cavity can improve heat insulation effect, and the coil brace outer wall is provided with shape as required, when the winding electromagnetic heating coil is installed, only needing the general staff to twine gets final product, specification requirement is not high, is easy to install, and need not to adorn post debugging, save time, the saving of labor has saved installation cost; Its two because insulation outer exterior wall face is the face of cylinder, is more conducive to improve electromagnetism and adds thermal effect; Its three because described bracing frame is provided with plurality of air and is provided with air blast in bracing frame one side, when pending material requirements was low than the material temperature of handling, as first processing nylon material, the temperature of its requirement was 250 ℃; Post processing polypropylene material, the temperature of its requirement are 200 ℃, like this, just plastic machine barrel temperature inside need be reduced to 200 ℃, present device just needs to wait for for a long time, and this device only need be opened the air port and gets final product, faster if desired, then open blower fan; Its four because described insulation outer exterior wall face is provided with groove, made things convenient for the winding of insulated coil, and can be convenient to the insulation of coil so that separated by a distance between the insulated coil; Its five because described coil brace is formed at least two sub-coil supports that surround the annulus tube mutually, each sub-coil support is provided with vacuum separately and divides cavity, has made things convenient for the installation of coil brace.
Description of drawings
Fig. 1 is the structural representation of the utility model plastic machine with electromagnetic heater;
Fig. 2 is B-B cutaway view of Fig. 1;
Fig. 3 is the bracing frame side view;
Fig. 4 is the structural representation of two sub-coil supports for coil brace.
The specific embodiment
Below in conjunction with accompanying drawing structure and the use principle of the utility model plastic machine with electromagnetic heater is described in further details.
As depicted in figs. 1 and 2, the utility model plastic machine is included in the outside coil brace 2 that is with and the insulated coil 3 that is wrapped on the coil brace 2 of plastic machine barrel 1 with electromagnetic heater, coil brace 2 is made up of insulation inwall 21 and insulation outer wall 22, and insulation inwall 21 and insulation outer wall 22 surround the cavity 23 of vacuum.Insulation inwall 21 and insulation outer wall 22 adopt insulation insulation and non-magnetic material to make.Coil brace 2 is fixing with plastic machine barrel 1 by the bracing frame 4 that is positioned at coil brace 2 axial both ends.Because cavity 23 be vacuum, prevented the heat loss, improved fractional energy savings, reduced production cost, and coil brace 2 fully and plastic machine barrel 1 size be complementary, apparatus structure is fixed, and is easy to installation, need not to adorn post debugging, has reduced the Installation and Debugging cost.Convenient and the raising electromagnetism thermal efficiency for winding around, insulation outer wall 22 lateral surfaces of coil brace 2 are cylindrical.Certainly, according to the design needs, insulation outer wall 22 lateral surfaces also can be other shape.In order to prevent that insulated coil 3 is short-circuited, insulation outer wall 22 lateral surfaces are provided with groove 24, and insulated coil 3 snaps in the groove 24, and separated by a distance between the adjacent insulated coil 3.
In the plastic cement process, the raw material that often adopts a machine processing different temperatures to require, for example: handle nylon material earlier, the temperature of its requirement is 250 ℃; Post processing polypropylene material, the temperature of its requirement are 200 ℃, like this, just plastic machine barrel temperature inside need be reduced to 200 ℃, because coil brace 2 heat-insulating properties are good especially, need to wait for for a long time, have reduced production efficiency.In order to reduce the stand-by period, accelerate temperature and underspeed, as shown in figures 1 and 3, the outside of plastic machine barrel 1 and insulation inwall 21 clear width certain distances, bracing frame 4 is provided with plurality of air 5, and when needs were lowered the temperature, cold air entered the outside of plastic machine barrel 1.Enter the outside of plastic machine barrel 1 in order to accelerate cold air, be provided with when needs are lowered the temperature in bracing frame 4 one sides, open air blast 7, cold air enters the outside of plastic machine barrel 1 rapidly.
As shown in Figure 4, for convenience coil brace 2 is installed on the plastic machine barrel 1, coil brace 2 is that semi-circular sub-coil support 25,26 is formed by two cross sections, and sub-coil support 25,26 is provided with vacuum separately and divides cavity 27,28.Certainly, coil brace 2 also can be made up of two above sub-coil supports, and each sub-coil support surrounds the annulus tubular mutually, and the sub-coil support is provided with vacuum separately and divides cavity.
