Background technology
In life now, plastic products are extensively used by every field, when producing required plastic products, usually need plastic grain to carry out melting, thus need to use specially for the device of plastics melting.In prior art, conventional plastics melting plant is that heater wraps transmission rod, and heater is heated the plastic grain transmitting rod conveying by electrically heated mode, thus reaches the object of molten plastic.The mode of this heating and melting needs a large amount of electricity, makes the production cost of plastic products higher, and many research and development have been done for this problem by a lot of manufacturer, constantly improve this problem.As the patent No. is: one section of patent of CN201320389412, by the transmission screw thread transmitted on rod is carried out density adjustment, make plastic grain friction occur in course of conveying and produce heat, thus reach the object of power saving.But this structure can not tackle the problem at its root, transmit rod and driven by electric energy, transmit rod and also can expend certain electric energy when impelling plastic grain to rub.And easily make plastic grain rub with transmission rod and heater, thus reduce the service life of whole process units.
Summary of the invention
It is simple, easy to use that the object of the invention is to provide a kind of structure, effectively can realize the plastics melting plant that plastic grain saves electricity as much as possible in melting process.
For realizing above-mentioned technical purpose, use following technical scheme:
A kind of plastics melting plant, comprise metal cylinder, transmit rod, frame, motor, insulation heat preservation layer and heater coil, transmit rod to be made up of round bar and the transmission screw thread being arranged at round bar surface, transmitting rod is arranged in metal cylinder, transmit screw thread and metal cylinder contact internal walls, between round bar and metal cylinder, under the effect transmitting screw thread, form transmission space; Driven by motor transmits rod, transmits screw thread, according to direction of motor rotation, metal cylinder two ends is divided into feed end and discharge end; Be enclosed with one deck insulation heat preservation layer at metal cylinder outer wall, heater coil wraps is on insulation heat preservation layer; Metal cylinder and motor are arranged in frame.
For making the present invention more be suitable for practicality, make further improvements below:
Also comprise temperature inductor and controller, described temperature inductor is arranged at metal cylinder inwall, and temperature controller is connected with heating cables, motor and temperature inductor respectively.Heating-up temperature and material transferring speed can both be controlled effectively.
Described feed end is provided with feed hopper, convenient when making charging, reduces the risk that material is unrestrained.
Described transmission rod is that metal is made, and makes eddy-current heating effect more excellent.
Described insulation heat preservation layer is for receiving the heat insulation soft felt one-tenth of base, and make to reach excellent heat insulation effect in metal cylinder, plant running is more stable.
Beneficial effect of the present invention is: utilize electromagnetic inductive heating principle, heats in metal cylinder, and heat is tightly locked in metal cylinder by the insulation heat preservation layer being wrapped in metal cylinder outer wall.Owing to being directly heat for metal cylinder, making to decrease heater and heat is passed to this heat transfer process of metal cylinder, improve the efficiency of heating surface, thus reach the object of saving electricity.
