Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing and granulation technology, and in particular to an extrusion granulator. Background Technology
[0002] An adjustable twin-screw extruder granulator is a piece of equipment used in plastic processing. It is primarily used to produce granular products from plastic raw materials through processes such as heating, melting, mixing, and extrusion. Diverse production needs can be met by adjusting screw speed, heating temperature, and die changes.
[0003] During the extrusion process of a twin-screw granulator, the raw material moves towards the discharge port under pressure and friction. When the raw material is almost used up, some material remains at the discharge port and accumulates there. Therefore, it needs to be cleaned in time. However, the existing cleaning method requires the complete removal of the blades and the discharge port sealing plate, which is time-consuming and labor-intensive.
[0004] Therefore, it is worthwhile to further study how to provide more optimized and convenient twin-screw extruders for plastic processing to solve the above problems. Utility Model Content

[0015] Compared with existing technologies, the advantages of this utility model are:
[0016] I. This utility model, through its designed disassembly and assembly components, allows for simultaneous pressing of the telescopic locking block below the first fixed plate with both hands at the end of each granulation operation, and pulling down the connecting plate to disengage the telescopic locking block and the first insert rod from the first through hole, and the connecting plate and the step plate from the step groove. At this point, the raw material residue at the outlet of the mixing hopper can be cleaned. After cleaning, the step plate is installed back into the step groove following the steps described above. This design, with its quickly detachable step plate, facilitates timely cleaning of residue at the outlet of the mixing hopper, saving time and effort, and making operation convenient.
[0017] II. In this utility model, by setting up a protective component, when it is necessary to clean the raw material residue at the outlet of the mixing hopper, the second rod on the second fixed plate is pulled upward, so that the second rod moves upward along the third through hole. The lower end of the second rod moves out of the second through hole and pulls the U-shaped baffle along the slide groove, so that one end of the U-shaped baffle is attached to the sealing plate. At this time, the blade is located above the U-shaped baffle.
