[0004] The technical solution of the utility model is to facilitate the cleaning of the screw barrel of the extruder, comprising a shell, wherein a cavity for placing the screw is provided in the shell, including

[0005] The mounting cylinder is detachably connected to the shell, and a mounting cavity is axially provided on the mounting cylinder. The inner wall of the mounting cavity is provided with bristles. When the mounting cylinder and the shell are mounted together, the bristles are arranged in the cavity and opposite to the screw.

[0006] The installation cylinder comprises a cylinder wall, and the cylinder wall is provided with an installation groove for the shell to extend into.

[0007] A plurality of the mounting tubes are provided, and the plurality of mounting tubes are detachably connected to each other.

[0008] The mounting tubes are provided with flanges, and the flanges of adjacent mounting tubes are connected by screws.

[0009] The flange is provided with a mounting hole, and the mounting hole is communicated with the mounting groove and is mounted to the housing via a fastener.

[0010] The bristles are steel brushes.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a convenient way to clean the screw barrel of the extruder, and the screw in the barrel can be cleaned conveniently without dismantling the entire machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below in conjunction with the accompanying drawings: As shown in the figure, it is convenient to clean the screw barrel of the extruder, comprising a housing 1, a cavity 3 for placing the screw 2, and a mounting barrel 4 detachably connected to the housing. The mounting barrel is provided with a mounting cavity in its axial direction, and a brush 41 is provided on the inner wall of the mounting cavity. When the mounting barrel and the housing are installed together, the brush is arranged in the cavity and opposite to the screw 10. The mounting barrel is removed during normal operation, and when cleaning is required, the mounting barrel is installed, and then water and cleaning agent are poured into the barrel. The screw is started, and the brush will brush off the residual material on the screw, thereby completing the cleaning.

[0016] In this embodiment, as shown in the figure, the installation cylinder includes a cylinder wall 42, and the cylinder wall is provided with an installation groove 421 for the shell to extend into. The side wall of the installation cylinder is provided with an installation groove, which can be a through groove or a sunken groove. When the shell is inserted, the inner wall of the installation cylinder will be inside the shell.

[0017] In this embodiment, as shown in the figure, the mounting barrel is provided with a plurality of barrels, and the plurality of mounting barrels are detachably connected to each other. When a longer barrel is used, it can be used better.

[0018] In this embodiment, as shown in the figure, the mounting tube is provided with a flange 43, and the flanges of adjacent mounting tubes are connected by screws. The flanges are passed through horizontally by screws and fixed with nuts.

[0019] In this embodiment, as shown in the figure, the flange is provided with a mounting hole 431, which is connected to the mounting slot and is mounted to the housing via a fastener. Threaded holes are also provided on the outer wall of the housing, and fasteners (which may be bolts) are passed through the mounting holes and then connected to the threaded holes to secure the mounting tube.

[0020] In this embodiment, as shown in the figure, the bristles are steel brushes.

[0021] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0023] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. The embodiments should not be construed as limiting the present invention, but any improvements based on the spirit of the present invention should fall within the scope of protection of the present invention.
