The screw extruder comprises a speed reducing box and a sleeve which both are fixed on a base, an extrusion rod is arranged in the sleeve, a spiral blade is fixed on the outer surface of the extrusion rod, the input end of the speed reducing box is connected with a drive motor, one end of the sleeve is provided with a feeding hopper communicated with a cavity in the sleeve, and the other end of the sleeve is provided with a discharging pipe communicated with the cavity in the sleeve. The screw extruder is characterized in that the discharging pipe is provided with a manual valve adjustable in open degree. According to the screw extruder for polyamide fiber production, six slices of polyamide entering the cavity of the sleeve are extruded, the extrusion force of the six slices of polyamide in the sleeve can be adjusted by changing the opening degree of the manual valve, and the performance of materials processed by the screw extruder is guaranteed. The two ends of the extrusion rod are fixed on the sleeve in a rotating mode through a first bearing and a second bearing, friction of the extrusion rod in the rotating process is lowered, and energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of nylon fibre production screw extruder, in particular, relates in particular to a kind of nylon fibre production screw extruder that can regulate extruding dynamics.
Background technology
Chinlon 6 section, claims again polyamide 6 section, nylon 6 slice.Because containing amido link (one CO-NH mono-) in large molecule, therefore be called polyamide.The chinlon 6 section cylindrical particle shape that is conventionally white in color, fusing point is 210-220 ℃, decomposition temperature is 300 ℃ of left and right.Polyamide fibre is the best fiber of anti-wear performance in synthetic fiber.
The production process of nylon fibre comprise successively the dry section of polyamide fibre 6, section conveying, screw extruder, manifold, static mixer, measuring pump, filament spinning component, lateral blowing cooling forming, to silk oil, cold traction, sizing and coiling.Wherein to use screw extruder the chinlon 6 section of sending into is pushed, chinlon 6 section suffered extruding degree in screw extruder, the directly performance of the follow-up fiber of weaving out of impact.The suffered extruding of chinlon 6 section is excessive or too small, also can reduce the efficiency of wire vent.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of nylon fibre production screw extruder that can regulate extruding dynamics.
Nylon fibre production screw extruder of the present utility model, comprise that reduction box and the inside be fixed on base are the sleeve of cylindrical cavity, in the internal cavities of described sleeve, be provided with pressure ram, on the outer surface of pressure ram, be fixed with the screw blade that the chinlon 6 section to entering pushes; The input of reduction box is connected with drive motors, and the output shaft of reduction box is connected with one end of pressure ram by shaft coupling; One end of sleeve arranges the feed hopper communicating with the internal cavities of sleeve, and the other end is provided with the discharge nozzle communicating with the internal cavities of sleeve; Its special feature is: on described discharge nozzle, be provided with the adjustable manually-operated gate of aperture.
Base plays fixing and supporting role, and drive motors is used for ordering about pressure ram and rotates, and reduction box is arranged between drive motors and pressure ram, between reduction box and pressure ram, is provided with shaft coupling.Pressure ram is arranged in the internal cavities of sleeve, screw blade is fixed on the outer wall of pressure ram, in the internal cavities that chinlon 6 section enters sleeve by feed hopper, pressure ram is in the process of rotating, drive screw blade to realize the extruding to chinlon 6 section, chinlon 6 section after extruding is discharged by discharge nozzle 8, enters subsequent processing.Manually-operated gate is arranged on discharge nozzle, and can carry out regulation; By manually-operated gate, regulate the aperture of discharge nozzle, can change the be squeezed degree of chinlon 6 section in sleeve.
Nylon fibre production screw extruder of the present utility model, the two ends of described pressure ram are fixed on sleeve by clutch shaft bearing and the second bearing respectively.Pressure ram is fixed by clutch shaft bearing and the second bearing, effectively reduced pressure ram suffered friction in rotation process, effectively reduces the consumption of energy.
The beneficial effects of the utility model are: nylon fibre production screw extruder of the present utility model, by the pressure ram with screw blade is set in sleeve, pressure ram orders about by drive motors, has effectively realized entering the squeezing action of the chinlon 6 section in sleeve cavity; By manually-operated gate is set on discharge nozzle, by changing the aperture of manually-operated gate, adjustable chinlon 6 section suffered extruding force in sleeve, has guaranteed the performance of the material that processes by screw extruder.The two ends of pressure ram are fixed on sleeve rotationally by clutch shaft bearing and the second bearing, have reduced suffered frictional force in pressure ram rotation process, have reduced the consumption of the energy.
Accompanying drawing explanation
Fig. 1 is that nylon fibre of the present utility model is produced the structural representation with screw extruder.
In figure: 1 base, 2 drive motors, 3 reduction boxes, 4 shaft couplings, 5 sleeves, 6 pressure rams, 7 feed hoppers, 8 discharge nozzles, 9 manually-operated gates, 10 screw blades, 11 clutch shaft bearings, 12 second bearings.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, provided nylon fibre of the present utility model and produced the structural representation with screw extruder, it comprises base 1, drive motors 2, reduction box 3, sleeve 5, pressure ram 6, feed hopper 7, discharge nozzle 8 and manually-operated gate 9; Shown 1 fixing and supporting role of base, reduction box 3 and sleeve 5 are all fixed on base 1.The output shaft of drive motors 2 is connected with the input of reduction box 3, and the output shaft of reduction box 3 is connected with the left end of pressure ram 6 after shaft coupling 4.The inside of sleeve 5 is cylindrical cavity, and pressure ram 6 is arranged in the internal cavities of sleeve 5, and the outer surface of pressure ram 6 is screw blade 10.The two ends, left and right of pressure ram 6 are fixed on sleeve 5 rotationally by clutch shaft bearing 11 and the second bearing 12 respectively.
Feed hopper 7 and discharge nozzle 8 are arranged at respectively left end and the right-hand member of sleeve 5, and are all connected with the internal cavities of sleeve 5.Chinlon 6 section enters by feed hopper 7 in the internal cavities of sleeve 5, and pressure ram 6 rotates under the drive of drive motors 2, the squeezing action realizing chinlon 6 section by screw blade 10.Chinlon 6 section after extruding is discharged by discharge nozzle 8, to enter subsequent processing.On discharge nozzle 8, be provided with manually-operated gate 9, by changing the aperture of manually-operated gate 9, stressed in screw extruder of adjustable chinlon 6 section, meets the requirements polyamide fibre 6 materials that process.
