Description
Technical field
This utility model relates to a kind of extruder.
Background technology
Extruder mainly includes screw rod, machine barrel, hopper, head and mould, and plastics are plastified uniformly by extruder
Under melt, and set up pressure, by screw rod continuous print extruder head.
Wherein feed hopper bottom is equipped with cutting device, in order to adjust and cut off stream, and the side of hopper is equipped with window and demarcation
Metering device.
The cutting device of prior art is mainly used in after machine breaks down stopping it to overhaul or manual operation
Adjust flow, function singleness；And the pressure of feed hopper bottom also can by the difference of inventory (namely the degree of depth of material is different)
Difference, causes under each phase scenario, and same hopper outlet has different flows and causes discharging uneven；Furthermore, extrusion
Machine lacks material alarm device, needs hand inspection clout, improves the fussy degree of operation, and inconvenience produces.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of extruder.
For achieving the above object, this utility model provides following technical scheme: includes packing cylinder, feeding chamber, hopper, subtract
Speed machine and the screw rod being arranged in packing cylinder, described feeding chamber is arranged at the top of hopper, and described packing cylinder is arranged at hopper
Lower section, described reductor is connected to screw rod, and described feed hopper bottom is provided with cutting device, it is characterized in that: also include display screen,
PLC and pressure transducer, described pressure transducer is provided with multiple, and is respectively arranged at the side of hopper and feeding chamber
Wall；Described cutting device includes motor and regulation valve, and the output shaft of described motor is connected to regulate the regulation wheel of valve；Described display
Screen, motor and pressure transducer are all electrically connected at PLC.
Its sidewall can be produced a pressure, side by the material existed in technique scheme, packing cylinder and in hopper
The pressure transducer of wall can sense this pressure, the pressure transducer when topmost sense pressure interval scale its at full capacity,
Not recycling；Lack less than the material in pressure interval scale hopper when the pressure transducer of bottom senses, need to increase material；
Each pressure transducer represents the amount of a material, by the connection of pressure transducer Yu PLC, the number of inventory
And pace of change is shown on display screen, PLC judges the material in hopper according to the pressure data received simultaneously
Pressure bottom the degree of depth and packing cylinder, thus control to adjust the opening degree of valve to control hopper discharging by controlling motor
Speed, makes discharging more stable, uniformly.
Preferably, the regulation wheel of described regulation valve being arranged porose, the inside edge in described hole is provided with internal gear, described electricity
The outer edge of the output shaft of machine is provided with the external gear being meshed with internal gear.
By technique scheme, output shaft engages each other fixing connection with regulation wheel by internal gear and external gear.
Preferably, described reductor is electrically connected at PLC.
By technique scheme, PLC controls the speed of reductor, to adapt to charging and discharging needs.
Preferably, the plurality of pressure transducer longitudinal arrangement is arranged.
By technique scheme, the pressure transducer of longitudinal arrangement is to detect the degree of depth of material.
Preferably, described PLC is also associated with alarm device and multiple display lamp.
By technique scheme, driven by PLC when the pressure transducer of bottom does not sense pressure and report to the police
Device is reported to the police, and reminds workman to need charging, and the pressure transducer of the top and bottom is all to having corresponding display lamp, just simultaneously
Observe intuitively in operator is convenient.
