Wire box

Abstract

The invention relates to a silk box for a three-dimensional (3D) printer. The silk box comprises a box body with a silk outlet and a reel which is rotatably arranged in the box body. The silk box also comprises a metering unit, a friction unit and a display unit, wherein the metering unit is arranged beside the silk outlet of the silk box and is used for metering the use amount of the silk; the friction unit is used for controlling the silk outlet strength and rate of the silk box; the display unit is used for displaying the balance or the used amount of the silk in the silk box. The balance or the used amount of the silk in the silk box can be provided, so that whether the silk box needs to be replaced is conveniently decided according to further printing demands, and the silk feed rate of a feed roller to an extrusion head can be improved, and the silk feed strength is controlled.

Description

technical field [0001] The invention relates to a component of a 3D printer, in particular to a filament box for a 3D printer. Background technique [0002] A 3D printer is a device based on a digital model that uses materials such as powdered metal or plastic to construct three-dimensional objects by layer-by-layer printing. One of the 3D printers supplies molding materials to the extrusion head in the form of filaments. The molding materials are heated to a molten state by electric heating in the extrusion head. The extrusion head will follow the extrusion head generated by the 3D printer host. The path moving relative to the substrate prints the three-dimensional object layer by layer. The molding material is wound in the filament box in the form of filaments. When the filament of a filament box is printed, the filament box needs to be replaced to allow the 3D printer to continue printing. [0003] The existing low-cost 3D printer mainly adopts the filament box describe...

AI Technical Summary

Problems solved by technology

In order to save costs, the controller of the low-cost 3D printer cannot calculate the remaining amount of wire in the wire box, so when there is no wire in the wire box, it cannot remind the user to replace the wire box; When modeling an object, you can initially estimate the corresponding amount of filament used, but since the remaining amount of filament in the filament box cannot be estimated, it is impossible to judge whether the remaining filament in the filament box is sufficient, which may cause problems during the printing process. If the filament is not enough, the filament box needs to be replaced, which will affect the printing process and printing quality; because the filament 02 in the reel 01 is in a loose state, it is not conducive to the feeding speed and strength of the feeding roller 0321 and 0322 to the extrusion head 031 control; because the reel 01 has no shell protection, for ABS thermoplastics and other moisture-sensitive materials, the filament is easy to contact with moisture in the air, and it is easy to become damp, which will affect the printing quality
