Description
Technical field
The invention belongs to extruding machine technical field, especially relates to a kind of extruding machine heater.
Background technology
In plastic article industry, plastic products complete on extruding machine, in production process by the feedstock transportation of liquid state in feed pipe, under the effect of screw rod by feedstock transportation in mould, then through supercooling, required plastic products are formed under the effect of mould, in order to ensure the quality requirement of plastic products, require that the raw material entered in mould keeps certain temperature, in prior art, the mode taked to reach this requirement is mostly at feed pipe peripheral hardware having heaters, ecto-entad provides heat, such as application number be 201120444913.4 application take this mode of heating, the shortcoming of this mode of heating is that heat outwardly runs off, and then cause increasing of production cost.
Summary of the invention
In view of this, the invention is intended to propose a kind of extruding machine heater, the problem of heat losses during to solve feed pipe external heat in prior art.
For achieving the above object, the technical scheme of the invention is achieved in that
A kind of extruding machine heater, comprise feed pipe, hollow shaft, screw blade and water back, described hollow shaft is arranged on support, and this hollow shaft is connected with holder pivots, one end of described hollow shaft is blind end, the other end of this hollow shaft is open end, the blind end of described hollow shaft extend in feed pipe, described screw blade is positioned at feed pipe, and described screw blade is fixed in the axle surface of hollow shaft, described hollow shaft is connected with motor in open end, described water back is positioned at hollow shaft, and the open end of injection hollow shaft is worn in one end of this water back, described water back is circumscribed with hot gas source.
Further, exhaust mechanism is provided with between described hollow shaft and water back, described exhaust mechanism is arranged on the open end of hollow shaft, described exhaust mechanism comprises circular cover plate, described cover plate is socketed on water back, be provided with seal between described cover plate and hollow shaft, described cover plate is provided with multiple air-vent, is respectively equipped with plug stifled in described multiple air-vent.
Further, the outer circumference surface of described cover plate is provided with seal groove, and described seal is positioned at seal groove.
Further, described air-vent quantity is four, and these four air-vents are arranged into an array.
Further, described motor is connected by belt with hollow shaft.
Relative to prior art, the extruding machine heater described in the invention has following advantage:
(1) the extruding machine heater structure described in the invention is simple, extraneous hot gas source provides heat by water back to hollow shaft, hollow shaft carries out heat trnasfer, transfer heat to the raw material in feed pipe, ensure that raw material temperature, ensure that carrying out smoothly of extrusion molding, and then ensure that the quality of plastic products, in this transfer mode, heat can not outwardly distribute, because this reducing production cost.
(2) in the extruding machine heater described in the invention, controlled the capacity of returns of hot gas by the number that adjustment plug is stifled in the arranging of exhaust mechanism, and then the temperature in control hollow shaft, ensure that the raw-material temperature in feed pipe, further ensure the quality of plastic products.
