Description

Technical Field

[0001] The utility model relates to the technical field of screw extruders, in particular to a feeding device for a parallel twin-screw extruder. Background Art

[0002] Twin-screw extruder is a common engineering plastic molding equipment, widely used in the filling, reinforcement, toughening and other blending modifications of plastics, engineering plastics, thermoplastics, rubber and other polymer materials, as well as special fibers, special adhesives and other processing fields.

[0003] A twin-screw extruder typically consists of a barrel, twin screws rotating within the barrel, an extrusion head, and a hopper connected to the barrel. The extrusion head is mounted at the barrel's output end. Mixed plastic masterbatch enters the barrel from the hopper, where the meshing twin screws push the plastic forward. The plastic is then extruded through the extrusion head to form plastic strands.

[0004] Regarding the above-mentioned related technologies, the inventors believe that if metal debris is mixed into the plastic masterbatch during the production and feeding process, it will not only affect the quality of the plastic output, but also damage the twin-screw, affecting the plastic processing and production process.

The rotation of the output end of the first motor 7 can drive the rotating shaft 5 and the stirring rod 6 to rotate at the same time, and the plastic masterbatches in the shell 4 can be stirred to mix the different types of plastic masterbatches.

[0037] A pair of electromagnets 8 are provided on the inner lower end surface of the housing 4;

[0038] The staff electrically connects the electromagnet 8 to an external power source, which can generate a magnetic field to absorb the metal debris in the plastic masterbatch and improve the quality of the plastic masterbatch;

[0039] The conveying device is provided on the upper end surface of the carrying plate 3 and is used to convey the plastic masterbatch in the shell 4 to the feed hopper 2 .

[0040] Specifically, the conveying device includes:

[0041] The conveying shell 9 is fixedly mounted on the upper end surface of the carrying plate 3;

[0042] The feed pipe 10 is connected to the housing 4 at one end and to the conveying shell 9 at the other end;

[0043] The auger 11 is rotatably mounted in the conveying shell 9;

At the same time, the plastic masterbatch in the shell 4 can flow from the feed pipe 10 to the conveying shell 9. At this time, the auger 11 rotates to convey the plastic masterbatch in the conveying shell 9, and the plastic masterbatch flows from the discharge pipe 13 to the feed hopper 2.

[0047] Specifically, two pairs of moving wheels 14 are rotatably mounted on the lower end surface of the carrying plate 3;

[0048] Under the action of the two pairs of moving wheels 14 , it is convenient for workers to move the carrying plate 3 .

The rotation of the output end of the first motor 7 can drive the rotating shaft 5 and the stirring rod 6 to rotate at the same time. At this time, the staff adds different types of plastic masterbatches into the shell 4. At this time, the rotation of the stirring rod 6 can stir different types of plastic masterbatches and mix them. At the same time, when the plastic masterbatches are mixed, the electromagnet 8 can adsorb metal debris in the plastic masterbatch, which can improve the quality of the plastic masterbatch. At this time, the mixed plastic masterbatch flows from the feed pipe 10 to the conveying shell 9. At this time, the second motor 12 is started, and the second motor 12 can drive the auger 11 to rotate. At this time, the rotation of the auger 11 can convey the plastic masterbatch in the conveying shell 9, so that the plastic masterbatch flows from the discharge pipe 13 to the feed hopper 2, and fills the twin-screw extruder body 1, which facilitates the twin-screw extruder body 1 to process the plastic masterbatch, bringing convenience to people.
