Referring to fig. 8, the pressure regulating mechanism 9 is also different from that in embodiment 2 in that a guide shaft 93 is fixedly disposed on the slider 92, the guide shaft 93 is disposed along the vertical direction, and the guide shaft 93 penetrates through the mounting frame 15 and is slidably connected thereto. When the slider 92 moves, the guide shaft 93 can push the mounting frame 15 to move in a direction close to or away from the extrusion wheel 2, and simultaneously, under the guiding effect of the arc-shaped guide rail 17, the mounting frame 15 can also slide up and down on the guide shaft 93, so that the function of rotating the mounting frame 15 around the axis of the conveying roller 61 is realized, and the structure is simple and practical.
The implementation principle of the continuous extruder in the embodiment of the application is as follows: through set up conveyer belt 6 and compression roller 7 in the below at extrusion wheel 2 and scraper 5, the waste material of scraping 5 scrapes off 1 inboards in the frame, and be banded and mixed and disorderly waste material when passing through compression roller 7, can be for comparatively regular shape by compression roller 7 compaction, the volume and the burr deckle edge of waste material have been reduced, make things convenient for follow-up collection processing to the waste material, the staff is difficult by the fish tail when carrying the waste material, the convenience of waste material clearance in the continuous extrusion machine of models such as MFCCE500 and MFCCE700 has been improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
