Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In figure: axle sleeve 1, extruder 2, feeding inlet 3, support plate 4, temperature sensor 5, screw rod 6, heater 7.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Referring to attached drawing 1, this sealing system disclosed in the utility model is changed on the basis of existing extruder
Into its feeding inlet is directed at the material feeding region in the middle part of it, is divided into low-temperature space, material feeding region and feeding along axis inside entire extruder
Three, area region controls its regional temperature by control heater realization.
Sealing system includes screw rod 6 and axle sleeve 1.Both ends inside extruder 2 are separately provided for the branch of studdle 6
Fagging 4, screw rod is rack-mounted inside extruder along extruder axis direction, and bearing is set between screw rod and support plate.
It is divided into the low-temperature space of intermediate material feeding region B, left side inside extruder along its axial direction, according to material conveying direction
The feed zone C of A and right side.Having heaters 7 and temperature sensor 5, temperature sensor and setting are respectively set in each region
Controller outside extruder is wirelessly connected, and realizes data transmission.For material requirement, controlled by the control to heater
Actual temperature in each region processed, temperature sensor are used to monitor the actual temperature in region.Temperature sensor will be in region
Actual temperature be sent to controller by being wirelessly connected, after controller receiving data signal, after via controller processing, control plus
Hot device starting is closed, or the heating aperture of control heater, realizes the control to temperature in region.
The feeding inlet 3 of extruder is corresponding with intermediate material feeding region.
Screw rod is second level screw rod, and the screw thread including the opposite rotation direction of two-stage: it is anti-for being placed in the screw thread of the screw surface of low-temperature space
To thread segment, the screw thread of the screw surface of material feeding region and feed zone is placed in as positive thread segment.The reverse thread section of screw surface
Account for the 1/4-1/3 of entire spiro rod length.The screw thread of the reverse thread section of screw surface is low thread, and thread height is 0.5-
1.5mm.The screw thread of the forward screw thread section of screw surface is high thread, and thread height is 2-3mm.The length of axle sleeve accounts for the screw rod
The 1/2-2/3 of surface reverse thread segment length.
Low-temperature space A is provided with an axle sleeve 1, which is arranged concentrically with screw rod, and one end of axle sleeve is fixedly installed in support plate
Side on, or to be welded and fixed, or to be screwed.The internal diameter of axle sleeve is greater than the screw surface reverse thread section outer diameter 1-
1.5mm.Gap between axle sleeve and screw rod constitutes sealing area.
The preset temperature of the low-temperature space is 85-98 DEG C；The preset temperature of the feed zone is 180-200 DEG C；It is described go out
The preset temperature for expecting area is 120-160 DEG C.
The temperature of low-temperature space is significantly lower than the temperature of material feeding region, and after material drops down onto material feeding region by feeding inlet, material is with screw rod
It rotates and is sent by two-stage screw thread to opposite both direction, be sent to the material of low-temperature space, since temperature is lower in the area,
The phenomenon that will appear condensation, and the material for being delivered to sealing area between axle sleeve and screw rod slowly can be accumulated and be condensed, and constitute one
A closely knit sealing shroud, and the length of sealing shroud is more than or equal to the length of axle sleeve, the tail end of sealing shroud close to material feeding region, behind into
Entering can rotate after the material in the region is stopped by sealing shroud with screw rod to feed zone movement.Although low-temperature space temperature be lower than into
Expect area and feed zone, but its temperature can also guarantee that material in liquefaction, is wrapped in the outside of screw rod reverse thread section simultaneously
As the rotation of screw rod rotates together.Forward screw thread section realizes the normal conveying of material, and low-temperature space adds heating amount to be significantly lower than
Heating region and temperature in extruder cavity are reduced in other two regions, reduce energy consumption, improve working efficiency and quality.
