Intelligent anti-sticking spool for 3D printing

Abstract

The invention belongs to the technical field of 3D printing and provides an intelligent anti-sticking spool for 3D printing. The intelligent anti-sticking spool comprises a control module and a spoolholder, wherein a unidirectional extruding mechanism, a consumable driving mechanism and a laser ranging device are arranged on the spool holder; the unidirectional extruding mechanism comprises a discharging box, a ratchet wheel, a feeding mechanism and a code disc counter; a clearance is left between the feeding mechanism and the ratchet wheel to allow a filament to pass through; the code disc counter is arranged above the ratchet wheel and used for measuring the rotational speed of the ratchet wheel; the consumable driving mechanism comprises a driving motor, a connecting shaft and a central shaft, which is connected with an output shaft of the driving motor through the connecting shaft; a consumable is fixedly arranged at the periphery of the central shaft; the laser ranging device isused for measuring the radius of the consumable; and the control module is used for measuring the drawing speed of a printer according to a measurement value of the code disc counter and for controlling the rotational speed of the driving motor according to the drawing speed of the printer and the radius of the spool. The intelligent anti-sticking spool can prevent sticking during printing and canbe widely used in the field of 3D printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an intelligent anti-jamming tray for 3D printing. Background technique [0002] The FDM 3D printers currently on the market, due to defects in the quality control of the manufacturer and improper operation by the user, can easily lead to material jams and knotted wires during the printing process. In daily 3D printing work, it is impossible to supervise 24 hours a day. The material phenomenon may make ten or even dozens of hours of printing work fall short, ranging from wasting consumables to delaying the planned construction period. After summarizing experience and research, the main reasons for the material tray jamming problem are: 1. The quality control problem of the manufacturer, there is a wire winding problem when leaving the factory; 2. Improper operation by the user, the wire is loose when it is idle, and the wire is wound in disorder. Re-tighten the wi...

[0002] The FDM 3D printers currently on the market, due to defects in the quality control of the manufacturer and improper operation by the user, can easily lead to material jams and knotted wires during the printing process. In daily 3D printing work, it is impossible to supervise 24 hours a day. Material phenomenon may make ten or even dozens of hours of printing work fall short, ranging from wasting consumables to delaying the planned construction period

After summarizing experience and research, the main reasons for the material tray jamming problem are: 1. The quality control problem of the manufacturer, there is a wire winding problem when leaving the factory; 2. Improper operation by the user, the wire is loose when it is idle, and the wire is wound in disorder. Re-tighten the wire when it is used again, which may cause the wire to be stuck

Therefore, in order to solve the waste of consumables, time, electricity, and machine wear and tear caused by material jams and printing failures, it is necessary to improve the printer tray to avoid waste of consumables and time, and improve the printing experience
