Description

Technical Field

[0001] The utility model relates to the technical field of threaded elements, in particular to a protective device for a twin-screw extrusion threaded element and the threaded element. Background Art

[0002] Screw elements are key components in extruders and certain types of mixing equipment, especially twin-screw extruders. They are designed to convey, mix, shear, and disperse materials.

[0003] On November 23, 2018, a Chinese utility model patent with publication number CN208135057U disclosed a prefabricated part transportation protection device, comprising a first protective component, a second protective component, and a metal rod. The first protective component is disposed on one side of a rectangular prefabricated part; the first protective component is provided with a through-hole, which overlaps with the through-hole on one side of the rectangular prefabricated part; the second protective component is disposed on the other side of the rectangular prefabricated part; the second protective component is provided with a through-hole, which overlaps with the through-hole on the other side of the rectangular prefabricated part; the metal rod is cylindrical in shape, with a radius smaller than the radius of the through-holes on both sides of the rectangular prefabricated part, and the metal rod passes through the through-holes on both sides of the rectangular prefabricated part. This utility model prevents damage to the edges and corners of the prefabricated part during transportation and assists in the erection of the prefabricated part.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing technology has low reliability and can only protect long-sized threaded components, but cannot protect short-sized threaded components, making the surface of the threaded components exposed to the air vulnerable to damage during transportation. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems that the existing technology has low reliability and can only protect long-sized threaded elements but cannot protect short-sized threaded elements, making the surface of the threaded elements exposed to the air easily damaged during transportation. A protective device for twin-screw extrusion threaded elements and the threaded elements thereof are provided.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The utility model describes a protective device for a twin-screw extruder threaded element and its threaded element, comprising two end cover plates; a first semicircular tube and a second semicircular tube are detachably fixedly connected between the two end cover plates; limiting grooves are provided in the first semicircular tube and the second semicircular tube; a movable semi-tube is slidably inserted in the limiting groove.

[0008] The utility model provides a protective device for a twin-screw extruder threaded element and the threaded element thereof, which has the following beneficial effects:

[0009] 1. The utility model provides limiting grooves in the first and second semicircular tubes, into which movable half-tubes are slidably inserted, so that long threaded elements can be placed in the movable half-tubes, and a large number of short threaded elements can also be placed at the same time;

[0010] 2. The utility model uses elastic parts to buffer and limit the left and right movement of the movable semi-tube in the first semi-circular tube and the second semi-circular tube, so that the movable threaded element is safer when used and no collision occurs during transportation.
