Abstract
The utility model relates to a heater for an internal heating plastic machine, which is composed of a barrel, a center screw, an electric heating component, a temperature sensor, a nozzle, a hopper, a shaft coupling, a driving shaft, etc., wherein, the center screw is made into a cylindrical blind hole, and a heating ceramic rod is inserted in the hole. High temperature conducting wires connected with the heating ceramic rod are fixed on a multi-head ring of an electrical brush, wherein, the multi-head ring of an electric brush is arranged on the tail part of the screw, the circular barrel is sheathed outside the screw, and a gap is kept between the center screw and the circular barrel. The electric brush is fixed on the barrel and is corresponding to the ring of an electrical brush, and a heat insulating layer is wrapped at the periphery of the barrel. The internal heating heater for the plastic machine has the advantages of fast heating, small heat loss, obvious energy saving effects and improved working environment, and puts an end to the accidents of electric shock and scalds.
Description
The utility model belongs to a kind of heater of molding machine, relates to a kind of heater of internal heat type molding machine.
Existing molding machine comprises various types of injection machines and extruder, all adopts the heater of external-heat.The design feature of this heater is: go into a solid screw at barrel liner, and the heating collar of heating usefulness is fixed on the machine barrel.The mode of heating of this structure, because of heating part all is arranged on outside the tube, so heat scatters and disappears in the space greatly, the thermal efficiency is quite low.Molding machine is not only power consumption in process of production, and causes workshop temperature height, and especially in the summer of sweltering heat, the high temperature that equipment gave out causes work under bad environment, gets an electric shock simultaneously, scalds also and happen occasionally.
The purpose of this utility model provides a kind of heater of internal heat type molding machine, the thermal efficiency of molding machine significantly improves and reduced the consumption of the energy, has stopped the generation of electric shock, scald accident, has improved working environment effectively.
The purpose of this utility model realizes by following scheme: the heater of internal heat type molding machine is by machine barrel, center bolt, electrothermal piece, compositions such as temperature sensor, nozzle, hopper, shaft coupling, driving shaft.Described center bolt is made blind cylindrical hole, inserts multi-stag heating porcelain rod in the hole.The high temperature wire that connects heating porcelain rod causes the center bolt afterbody, is connected on the bull brush ring that is fixed in screw rod tail.Center bolt is with circular machine barrel outward, leaves the slit between screw rod and machine barrel.Be fixed with brush on the machine barrel, brush is corresponding with bull brush ring, and the machine barrel periphery is wrapped in heat-insulation layer.
The heater of molding machine changes internal heat type into by external-heat, and heat is outwards transmitted by the center during heating, and heat is almost all absorbed by plastics, so thermal efficiency height; Because heating porcelain rod inserts in the cored screw, avoided in addition to space heat elimination; Add the insulation layer in the outside of machine barrel, make the thermal loss minimum, energy-saving effect is quite remarkable; Simultaneously because the cored screw diameter that adopts is bigger than the diameter of real core screw rod, then under identical preformed amount condition, plastics attenuation to be heated between screw channel, the plastics of required heating are warm easily, and are not only energy-conservation, and improved production efficiency, total energy-conservation reaching more than 30%.Meanwhile, improve working environment, improved the security of equipment, stopped the generation of electric shock and scald accident.
Fig. 1 is a generalized section of the present utility model
The utility model is described in further detail below in conjunction with drawings and Examples:
In accompanying drawing 1, center bolt 1 is a blind cylindrical hole, inserts multi-stag heating porcelain rod 2 in the hole.Heat the porcelain rod and make multi-stag, can respectively to each work section heating, when also being simultaneously the damage of porcelain rod, be convenient to single replacing according to producing needs.3 of high temperature wires that connect multi-stag heating porcelain rod adopt inserting mode, and high temperature wire is caused the center bolt afterbody, are connected on the bull brush ring 4 that is fixed in screw rod tail.Outside the center bolt 1, be with a circular machine barrel 8, leave the slit between screw rod and machine barrel.Be fixed with brush 5 on the machine barrel 8, brush 5 is corresponding with bull brush ring 4.Brush 5 is done relative motion along the tangential direction of brush ring 4 during work.Electricity can guarantee that in the elasticity of brush screw rod 1 has good the contact with the brush ring in rotary course, thereby supplies with heating porcelain rod electric energy continuously.The tail end of above-mentioned screw rod 1 joins by shaft coupling 6 and driving shaft 7.(when molding machine is extruder, then connect electric rotating machine by driving shaft; When molding machine is injection machine, then connecting hydraulic motor by driving shaft) described machine barrel 8 is fixed on the main engine bed, and dividing on the machine barrel on each work section of work section (before, during and after district) has a blind hole, inserts temperature sensor 9 in the small blind hole, with the control temperature.The coated outside of machine barrel 8 has the heat-insulation layer 10 of rock wool or other insulation material, and heat-insulation layer can prevent that heat scatters and disappears.The front end of machine barrel 8 adopts thread nozzle to connect nozzle 11, and there is feed opening machine barrel afterbody top, and feed opening joins by ring flange and hopper 12.
When molding machine is an injection machine, the plastics during production between machine barrel and the screw slot are heated to form molten molten shape, and plastics at this moment have plenty of the particle that gets off from the material mouth, the remaining cooling material piece that gets off when also having plenty of last work.After treating that plastics are molten molten, start driving shaft, drive screw rod 1 rotation, screw rod is done parallel motion in rotation.After a last action of injection was finished, screw rod was in position foremost.When screw rod begins to rotate, material between screw channel lead-screw in rotation moves backward, when screw rod is pulled to rearmost end, pre-plastic process is finished, injection cylinder by screw rod tail provides power again, lead-screw travels forward, and the plastics that melt molten shape is penetrated from nozzle 11, thereby finish the full course of work of injection.
When molding machine is an extruder, when multistage heating porcelain rod 2 heating reach uniform temperature, start the driving shaft place and connect motor during production, make screw rod 1 rotation.Because screw rod and machine barrel, support are fixed together, the interaction force that screw channel and plastics produce is pushed plastics to the place ahead, and passes through nozzle 11 with the plastic extruder tube.
