Self-cleaning method and system for double-screw device

Abstract

The invention relates to a self-cleaning method and system for a double-screw device. According to the self-cleaning method and system for the double-screw device, the problem of material adhesion of a double-screw device in the prior art is solved. A protruding part I of a first screw and / or a protruding part II of a second screw are / is rotated to a preset position; the protruding part I relatively moves in the forward direction in one lead of the screw; it is judged that the relative distance between the protruding part I and the protruding part II is not smaller than a preset distance A, and the protruding part I is enabled to move in the counter direction in one lead of the screw; and it is judged that the relative distance between the protruding part I and the protruding part II is smaller than a preset distance B. The self-cleaning system for the double-screw device comprises a position detection unit and an input end of a control unit electrically connected with the position detection unit, and an output end of the control unit is electrically connected with two driving devices respectively; and the position detection unit is used for collecting and processing position information of the protruding parts, the control unit is used for controlling a first driving device and a second driving device to rotate, the first / second driving device is used for driving the first / second screw to rotate, the system can automatically clean adhered materials, and the disassembly process is reduced.

Description

technical field [0001] The invention relates to the technical field of twin-screw devices, in particular to a self-cleaning method and system for a twin-screw device. Background technique [0002] The twin-screw device is developed on the basis of the single-screw device. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, and extrusion stability, it has been widely used in the field of extrusion or conveying products. . [0003] However, during the use of the double-helix device, due to the high viscosity of the mixing particles, its solid particles or dust are easy to stick to the screw of the double-helix device. If it is not cleaned in time, it will affect the mixing process. Reduce the mixing efficiency of the twin-screw device and affect the quality of the extruded product at the same time. And because the overall structure of the double-helix device is closed, it is inconvenient to disassemble, and it takes a lot of time to...

AI Technical Summary

Problems solved by technology

[0003] However, during the use of the double-helix device, due to the high viscosity of the mixing particles, its solid particles or dust are easy to stick to the screw of the double-helix device. If it is not cleaned in time, it will affect the mixing process. Reduce the mixing efficiency of the twin-screw device, while affecting the quality of the extruded product

And because the overall structure of the double-helix device is closed, it is inconvenient to disassemble and assemble. It takes a lot of time to assemble and disassemble the screw each time, which is not convenient for daily maintenance.
