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

[0029] As a description of the second embodiment of the present invention, only the differences from the above-mentioned first embodiment will be described below. The above-mentioned pair of elastic plates are replaced by a pair of springs, and one end of one of the springs in the pair of springs is fixed to the bottom of the base. On the side wall, one end of the other spring is fixed on the corresponding position of the face cover, and the other ends of the pair of springs are fixed with pressure blocks. When the face cover is installed on the base, the two pressure blocks are tightly pressed and form a cross-sectional area smaller than The cross-sectional area of ​​the filament channel.

[0031] As a description of the third embodiment of the present invention, only the differences from the above-mentioned first embodiment are described below, and the above-mentioned substrate and the control memory, sensor and display screen, elastic plate and alarm are replaced by a mechanical counter. The device is installed on the mechanical counter, and the rotating shaft of the mechanical counter is fixedly connected with the rotating shaft of the counting wheel. In this example, the elastic plate is electrically connected with the alarm as the opening switch of the alarm.

[0032]The idea of ​​the present invention is mainly to provide a metering unit for measuring the amount of wire used near the outlet of the wire box, a friction unit for controlling the force and speed of the wire output from the wire box, and a friction unit for displaying the wire output of the wire box. A display unit for the remaining or used amount of silk in the silk box; it is convenient for mon...

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...
