Description
Technical field
The utility model relates to plastic grain extrusion equipment field, particularly relates to a kind of twin-screw extrusion machine head for plastic grain.
Background technology
Plastic grain double screw extruder is mainly used in one or more plastic grain melt blending modifications processing, by twin-screw in the same way or rotate backward, realize the heating and melting to plastic grain, promote that between fused mass, various chain reaction is fully carried out in melt flows process, the melt-processed simultaneously realizing plastics is shaping.Plastic grain double screw extruder can carry out the processing of multiple plastic grain; but the melt processing temperature of each plastic grain there are differences; in process; often there will be the situation causing material fluidity difference because temperature adjusting is improper; at twin-screw extrusion machine head place because equipment internal-external temperature difference and pressure change cause plastics at head place semi-solid preparation; silt accumulation up, cause twin-screw extrusion machine head to block, the equipment that affects runs well.The solution of usual employing makes material melts mobility strengthen for significantly heating up to equipment or artificial unloading's head cleaning tamper, the former is time-consuming, equipment heating and cooling all need the long period, the latter requires great effort, and cross-head cooling is comparatively slow, head cooling during dismounting, plastics solidification, head blocking place equipment component and plastic bonding, dismounting difficulty.
Summary of the invention
According to above technical problem, the utility model provides a kind of twin-screw extrusion machine head for plastic grain, comprise hold-down support, heat block, mouth mould, it is characterized in that: also comprise instant heating device, described instant heating device comprises heat outlet washer, screw, filter screen, temperature sensor, heating controller, temperature indicator, power switch; Described hold-down support has screwed hole, described heat block is embedded is installed on hold-down support inwall, described heat outlet washer is connected by screw on fixing heat block, described filter screen is inlayed and is arranged in heat outlet washer, described mouth mould and hold-down support screw are connected and fixed, described heating controller is connected with heat outlet washer by wire, described heating controller is provided with temperature indicator and power switch, described sensor is fixedly mounted on heat outlet washer and filter screen junction, and described temperature sensor is connected with temperature indicator.
Described temperature sensor has N number of, and N >=2 are starlike is distributed in heat outlet washer and filter screen junction.
The beneficial effects of the utility model are: the utility model has installed instant heating device at head place; instant heating device can heat up to the plastics Fast Heating of head blocking, makes head place block material Flashmelt, and blocking material fluidity strengthens; smoothly by head, guarantee that flow channel is unimpeded.Instant heating device is the independent heating parts at head place, avoids the slow process that the overall heating, cooling in extruder temperature control zone is experienced, and decreases the too high impact caused plastic melt of thermal treatment zone bulk temperature.Heat outlet washer heat conductivility is good, heats up fast, for the head blocking that different materials causes, carries out corresponding temperature setting by heating controller, simple to operation.The conductive force of filter screen makes to fail the rapid melting of bulky grain plastics of complete melting under twin-screw shearing force by opening of sieve, reduces the risk of head blocking.The utility model can reduce the unconventional disassembling section of equipment except maintenance, has saved the time of operator, avoids the wearing and tearing of plant equipment in unloading process simultaneously.The utility model adopts intellectualized operation, improves materials processing speed, production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model instant heating device structural representation.
In figure, 1-hold-down support, 2-heat block, 3-mouth mould, 4-heat outlet washer, 5-screw, 6-filter screen, 7-temperature sensor, 8-heating controller, 9-temperature indicator, 10-power switch.
Detailed description of the invention
Shown in composition graphs 1, Fig. 2, the utility model is further described.
As Fig. 1, Figure 2 shows that a kind of twin-screw extrusion machine head for plastic grain, hold-down support 1 is plastic grain double screw extruder body junction component, heat block 2 is embedded is installed on hold-down support 1 inwall, heat outlet washer 4 is connected and fixed on heat block 2 by screw 5, filter screen 6 is inlayed and is arranged in heat outlet washer 4, mouth mould 3 is fastenedly connected by screw 5 with hold-down support 1, heating controller 8 is connected with heat outlet washer 4 by wire, heating controller 8 is provided with temperature indicator 9 and power switch 10, temperature sensor 7 is fixedly mounted on heat outlet washer 4 and filter screen 6 junction, temperature sensor 7 is connected by wire with temperature indicator 9.The starlike junction being distributed in heat outlet washer 4 and filter screen 6 of temperature sensor 7.
When head blocks, switch on power switch 10, according to rapidoprint temperature setting heating controller 8 temperature, heat outlet washer 4 is under the control of heating controller 8, rapid temperature increases is to temperature required, head place blocking plastics are under the heating of heat outlet washer 4, be rapidly heated melt-flow, temperature sensor 7 can Real-Time Monitoring melt temperature, melt plastics are monitored, filter screen 6 is under the heat transfer effect of heat outlet washer 4, melt plastics are heated, melt plastics are flowed to machine head port mould 3 place under the effect of device interior pressure, during by filter screen 6, fail the bulky grain plastics of complete melting under the pressure effect between the high temperature and molten plastic of filter screen 6, melting liquefaction is through the mesh of filter screen 6.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
