Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a plastic extrusion device. Background Art

[0002] Extruders rely on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die. Extruders can be basically classified into twin-screw extruders, single-screw extruders, and the less common multi-screw extruders and screwless extruders. When processing plastics, they need to be extruded and formed through an extruder.

[0003] For example, a plastic extruder with the authorization announcement number "CN221540601U" screens the raw materials during transportation and collects larger nodules. At the same time, the nodules can be quickly crushed after being collected, ensuring the efficiency of raw material transportation and avoiding blockage of raw materials. However, when the device is extruding plastic, it is not convenient to adjust the shape of the extruded plastic. When extruding plastic, the molten plastic needs to be extruded into one or more strips, but when extruding plastic, it is not convenient to adjust the shape of the extruded plastic, etc., resulting in reduced functionality of the device during use.

[0025] Working principle:

[0026] When extruding plastic:

[0027] The molten plastic is added into the interior of the extruder body 1 through the funnel 5, the external power supply of the servo motor 6 is turned on, and the output shaft of the servo motor 6 is started to rotate to drive the injection screw inside the extruder body 1 to rotate, so that the internal plastic can be transported to the nozzle 12 for extrusion.

[0028] Replacement process:

[0029] When it is necessary to extrude the plastic into a different shape, the operator turns on the external power supply of the hydraulic cylinder 202, starts the telescopic end of the hydraulic cylinder 202 to extend and drive the frame 203 to move synchronously, so that the frame 203 drives the blocks 204 on both sides to move synchronously, so that the blocks 204 can no longer be pressed against the trapezoidal plate 11, and at the same time, the blocks 204 are moved past the rightmost end of the nozzle 12 (there will be no collision with the blocks 204 when the nozzle 12 rotates), turns on the external power supply of the servo motor 28, starts the output shaft of the servo motor 28 to rotate and drive the round block 901 to rotate 180°, so that the round block 901 can drive the nozzles 12 on both sides to exchange positions through the rotating rod 903, and according to the above reverse operation, the blocks 204 on both sides are again pressed against the trapezoidal plate 11, so that the replaced nozzle 12 can be pressed to the right end of the extruder body 1, completing the replacement of the nozzle 12 and realizing the extrusion of the plastic into different shapes.

[0030] Nozzle replacement process:

[0031] When both nozzles 12 cannot meet the processing requirements, the operator removes the bolt 902 on the surface of the unused nozzle 12, pulls and disassembles the nozzle 12, and replaces the new nozzle 12 and installs and fixes it again. Under the action of the insertion rod 904 and the bolt 902, the nozzle and the rotating rod 903 can be ensured to be in a straight line, and can correspond to the extruder body 1 when rotating.
