Description

The utility model relates to devices for extrusion molding, i.e. passing the formed material through dies or nozzles that give the desired shape, and can be used to process plastic waste from 3D printing into a plastic filament rod for 3D printing.

Known device Strooder, designed for the manufacture of a plastic filament rod from plastic granules, mainly ABS and PLA plastic, intended for use in 3D printing, consisting of a device body, an extruder body, a heating element, a feed screw, a screw motor, a feed mouth and a nozzle ( https://www.kickstarter.com/projects/omnidynamics/strooder-first-truly-consumer-3d-printing-filament).

The disadvantage of the known device is the inability to use plastic waste from 3D printing as a raw material for the manufacture of a filament rod, which leads to the accumulation of plastic waste, which the user of the 3D printer usually throws away, and the lack of the possibility of processing it into a filament rod does not allow the user of the 3D printer save on the purchase of filament for 3D printing.

The task to be solved by the proposed utility model is to eliminate the above-described shortcoming.

The technical result, which allows solving the problem, is the expansion of the capabilities of the device, which consists in the processing of plastic 3D printing waste into a plastic filament rod.

The technical result is achieved by the fact that the device for processing plastic 3D printing waste into a plastic filament, consisting of a device body, an extruder body, a heating element, a feed screw, a screw motor, a feed mouth and a nozzle, additionally contains a feed hopper in the upper part of the feed mouth, installed above the loading mouth, the bottom of which is a metal plate with slots and a rectangular hole in the center, connected to the loading hopper by means of two linear guides located parallel to each other and allowing the loading hopper to move along the plane of the metal plate with slots and a rectangular hole in the center plate, under which there is a planer shaft with blades connected to the engine by means of a belt drive.

The cutterhead is installed in such a way that the blades mounted on the cutterhead can contact the 3D printing waste loaded into the feed hopper during its rotation through a rectangular hole, thereby crushing the 3D printing waste. With the ability to pre-shred 3D printed waste using a cutterhead and feed hopper mounted on linear guides above the feed inlet, the user is able to use 3D printed waste as raw material for making a 3D printing filament rod.

The technical result is illustrated by drawings:

in fig. 1 - A device for processing plastic waste from 3D printing (side view with a local section);

in fig. 2 - A device for processing plastic waste from 3D printing in operation (side view with a local section);

in fig. 3 - A device for processing plastic waste from 3D printing (top view with a local section).

The device for processing plastic 3D printing waste into plastic filament contains a device body 1, an extruder body 2, a heating element 3, a feed screw 4, a screw motor 5 4, a loading mouth 6, a nozzle 7, a loading hopper 8 in the upper part of the loading mouth 6, a metal plate 9 with a rectangular hole 11 and slots 14, linear guides 10, a planer shaft 12 with blades 13 connected to the engine 15 by means of a belt drive 16.

A device for processing plastic waste from 3D printing into plastic filament works as follows: waste from 3D printing is loaded from above into a loading bin 8 mounted on a metal plate 9 with a rectangular hole 11 and slots 14 and fixed to it through linear guides 10, with with which the loading hopper 8 is moved along the metal plate 9 in reciprocating movements so that the waste from 3D printing moves over the hole 11 of the rectangular shape of the metal plate 9 and at the same time comes into contact with the rotating cutter shaft 12 and the blades 13 mounted on it, which grind the waste from 3D printing to the state of fine crumbs, and the cutter shaft 12 is driven by an engine 15 connected to the cutter shaft 12 by means of a belt drive 16, after which the waste from 3D printing in crushed form is spilled into the feed neck 6 of the body 1 of the device for recycling plastic waste from 3D printing, getting there both through the rotation of the cutter shaft 12, and waking up through the slots 14 of the metal plate 9, after which, under its own weight, the crushed waste from 3D printing along the sheer walls of the loading neck 6 enter the extruder body 2, where with the help of the feed screw 4 , driven by the motor 5 of the screw 4, are pushed inside the extruder body 2 towards the nozzle 7 into the section of the extruder body 2, on which the heating element 3 is installed, which heats the extruder body 2 to a temperature suitable for melting the crushed waste from 3D printing , thereby turning the shredded waste from 3D printing into a heated plastic mass, which, under the pressure of the feed screw 4, is pushed through the nozzle hole 7 in the form of a filament rod.

Waste from 3D printing, processed in this way into a rod of filament, which can be wound on a spool using an auxiliary device (not shown in the drawing), makes it possible to obtain, after processing, a plastic filament ready for reuse in 3D printing.
