Description

Technical Field

[0001] The utility model relates to the technical field of extruder screw maintenance, in particular to an extruder screw cleaning device. Background Art

[0002] The extruder screw is a key component in a plastic extrusion line. It is primarily used to heat and pressurize solid granular raw materials (such as plastic pellets) and convey them through the extruder head to form a continuous melt stream, ultimately extruding them into the desired shape. During use, material may adhere to the screw. If not cleaned promptly, these residues will not only contaminate the product but may also accelerate wear of the screw and other mechanical components. Therefore, it is generally necessary to clean the screw after use.

[0003] At present, screws are usually cleaned by screw cleaning machines. The existing cleaning machines have a cleaning table with symmetrically arranged rotating cleaning brushes on the cleaning table. The machine places the screw on the working table of the cleaning machine, and then the staff moves the screw so that the cleaning brush on the cleaning machine can fully brush off the material on the screw. The existing method of cleaning the screw by manually cooperating with the cleaning machine can brush off the material on the screw, but due to the heavy weight of the screw, it is relatively difficult to move it manually, which is time-consuming and labor-intensive. In addition, during the cleaning process, if the screw tilts to the side, it is difficult to correct the screw manually, which may cause the screw to collide with the cleaning machine, thereby damaging the screw and affecting the service life of the screw.

[0004] Therefore, the existing method of manually cooperating with a cleaning machine to brush off the material on the screw has the problem of difficulty in manual movement, and it is difficult to correct the side tilt by manpower, which causes the screw to collide and reduces the service life of the screw.

[0035] In this embodiment, the screw is fixed by the screw bracket 3, the roller brush 22 is rotated inward to clean the screw, and the base 21 slides back and forth in the track on the guide rail plate frame 1 to drive the roller brush 22 to fully clean the screw, thereby achieving the effect of automatically cleaning the screw and avoiding collision of the screw during the cleaning process.

[0036] In order to enable the sweeper 2 to slide on the guide rail plate frame 1 and clean the screw, the following preferred embodiments are proposed.

[0037] like Figure 1 As shown, the track of the guide rail plate frame 1 includes a track groove 11, two guide rods 12 are arranged in the track groove 11, the base 31 is slidably installed on the two guide rods 12, and both sides of the track groove 11 pass through the side walls of the guide rail plate frame 1.

[0038] A fixing frame 33 is symmetrically provided on the base 31, and the roller brush 32 is mounted on the fixing frame 33;

[0039] A cleaning motor 34 is provided on the side of the fixing frame 33 , and the shaft of the cleaning motor 34 is connected to the roller shaft of the roller brush 32 via a cleaning belt 341 .

[0040] Specifically, the cleaning motor 34 can drive the roller brush 32 to clean, and then slide back and forth on the guide rod 12 through the base 31 to fully clean the screw.

[0041] The two sides of the track groove 11 penetrate the side walls of the guide rail plate frame 1, making it easy to clean the debris brushed off.
