Technical Field

The invention relates to the technical field of preparation methods of polylactic acid three-dimensional printing consumables.

Background

3D printing consumables on the existing market can only produce the printing consumables of single colour if need produce the colorful printing consumables of gradual change, then need the manual work constantly to put into the formula of different colours, and this process consumes a large amount of manual works, can have the colour mixture moreover and lead to the problem of colour difference, consequently need carry out technical upgrade.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a preparation method of a polylactic acid three-dimensional printing consumable, which has the advantages of producing multicolor polylactic acid printing consumables, reducing chromatic aberration, improving product quality and improving production efficiency.

The technical scheme adopted by the invention is as follows:

the preparation method of the polylactic acid three-dimensional printing consumable comprises the following steps:

a double-screw extruder is adopted, and a plurality of blanking devices and a controller are also adopted; the controller is electrically connected with the double-screw extruder, the switching device and each blanking device; each blanking device is provided with a plurality of feeding devices; the controller controls one blanking device to feed, the controller controls the switching device to communicate the blanking device with the interior of the extruder, the rest blanking devices are disconnected from the double-screw extruder and communicated with the interior of the extruder, after the time H, the controller controls the other blanking device to feed, the controller controls the switching device to communicate the blanking device with the interior of the double-screw extruder, and the rest blanking devices are disconnected from the double-screw extruder; the extruder melts and extrudes the received materials to obtain a product; the switching device comprises a plurality of conveying pipes, a plurality of electromagnetic valves, a collecting pipe and a discharge pipe; one end of each conveying pipe is correspondingly arranged below one blanking device and is communicated with the corresponding blanking device; the other end of each conveying pipe is communicated with an electromagnetic valve; the other end of each electromagnetic valve is communicated with the collecting pipe; one end of the discharge pipe is communicated with the collecting pipe; the other end of the discharge pipe is communicated with the double-screw extruder.

The switching device is a multi-way switching valve, the feeding device with the color which is about to be adopted is communicated with the double-screw extruder, the feeding devices with other colors are communicated in a cutting mode, residual toner in the charging barrel does not need to be cleaned in the whole process, and color difference change is avoided.

Namely, the controller is electrically connected with a plurality of color sensors.

The invention has the beneficial effects that: can produce the poly lactic acid printing consumables of polychrome, reduce the colour difference, promote product quality, improve production efficiency's advantage.
