Abstract
The invention discloses an infrared heating plastic extruder which comprises a machine shell (1), and is characterized in that a heating layer (4) is arranged outside the machine shell (1); an extrusion screw rod (2) is arranged in the machine shell (1); the extrusion screw rod (2) is connected with a motor (3); the extrusion screw rod (2) is internally provided with a cavity (5); the cavity (5) is internally provided with an infrared generator (8). According to the infrared heating plastic extruder, infrared heating is adopted, and an infrared ray has penetrating power and is capable of heating the inside and the outside at the same time in the heating process, so that the infrared heating plastic extruder is uniform in heating and good in heat efficiency; furthermore, infrared heating is rapid in temperature rise, easy in temperature control and high in safety. Compared with the prior art, the infrared heating plastic extruder has the advantages of being simple in structure, rapid in temperature rise, easy in temperature control, uniform in heating, and convenient to operate.
Description
Technical field
The present invention relates to a kind of infrared heating plastic extruder, belong to plastic extruder technical field.
Background technology
In prior art, plastic extruder generally adopts the mode of heating of casing outside.Shortcoming is that interior external heat is uneven, extrudes effect bad.Therefore some plastic extruder adds the heating element heater such as resistance wire, electrothermal tube in extrusion screw rod inside, makes homogeneous heating inside and outside plastic extruder,
But resistance wire, electrothermal tube firing rate are slow, and its mode of heating causes in the temperature near extrusion screw rod high, cannot penetrate in casing fast, uniformly by heat.
Summary of the invention
The object of the invention is to: provide a kind of infrared heating plastic extruder, firing rate is fast, more even to overcome the deficiencies in the prior art.
The present invention is achieved in that infrared heating plastic extruder, and it comprises casing, outside casing, be provided with zone of heating, in casing, be provided with extrusion screw rod, and extrusion screw rod connects motor, is provided with cavity, in cavity, places infrared generator in extrusion screw rod.
Aforesaid infrared heating plastic extruder, described extrusion screw rod is provided with temperature inductor.
Aforesaid infrared heating plastic extruder, is provided with radome outside described zone of heating.
The present invention adopts infrared heating, in heating process, because infrared ray has penetration power, heats inside and outside energy, homogeneous heating simultaneously, and the thermal efficiency is good, and infrared heating heats up rapidly, and temperature controls easily, and security is also high.Therefore compared with the existing technology, it is simple that the present invention has structure, heats up rapidly, the advantages such as temperature controls easily, homogeneous heating, easy to operate.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Detailed description of the invention
Embodiments of the invention: infrared heating plastic extruder, as shown in Figure 1, make casing 1, at casing 1 outer installation zone of heating 4, in casing 1, install extrusion screw rod 2, extrusion screw rod 2 connects motor 3, in extrusion screw rod 2, produce cavity 5, in cavity 5, place infrared generator 8.In order to temperature control is more accurate, on extrusion screw rod 2, multiple temperature inductor 6 can be established in subregion.At the outer radome 7 installed an aluminium sheet and make of zone of heating 4, in case infrared generator 2 fault causes infrared ray to leak.
During work, plastics are put into infrared heating plastic extruder, plastics are heated by zone of heating 4 and infrared generator 8 simultaneously.And according to the temperature that temperature inductor 6 is monitored, the in time power of adjustment infrared generator 8, whole extruder is heated evenly.Can also arrange multiple infrared generator 8 in extrusion screw rod 2, subregion is heated, and regulates more flexible.
Claims (3)
1. an infrared heating plastic extruder, it comprises casing (1), it is characterized in that: outside casing (1), be provided with zone of heating (4), extrusion screw rod (2) is provided with in casing (1), extrusion screw rod (2) connects motor (3), be provided with cavity (5) in extrusion screw rod (2), in cavity (5), place infrared generator (8).
2. infrared heating plastic extruder according to claim 1, is characterized in that: described extrusion screw rod (2) is provided with temperature inductor (6).
