AI Technical Summary
When the frame of an existing 3D printer moves close to the filament tray, the printing filament is prone to loosening, which can cause the filament to clump or accumulate, affecting the printing effect.
The system employs a coordinated approach involving a guide assembly, a moving frame, a translation assembly, a material feeding assembly, a lifting assembly, and a material unloading assembly to ensure that printing consumables always fall vertically and remain taut, preventing accumulation and tangling.
It effectively prevents printing consumables from tangling or piling up during transport, ensuring stable printing quality and improving printing results.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printer technology, and specifically to a 3D printer with a consumables guiding function. Background Technology
[0002] A 3D printer is a device that can create three-dimensional solid objects by stacking materials layer by layer based on three-dimensional model data. It integrates technologies from disciplines such as mechanics, electronics, materials, and computers, and is widely used in many fields. During printing, printing materials are fed to the print head, which heats and melts them, and then ejects them through nozzles to form the shape.
[0003] According to the search, for example, a 3D printer with a filament guiding function is proposed in the announcement number CN222116063U. The printer winds the printing filament onto a filament tray, and connects the other end to the print head through rollers on the frame. The frame can move back and forth and be adjusted, and the filament tray moves left and right on the drive screw, so that the printing filament and the print head can move synchronously.
[0004] However, since one end of the printing filament is inclined upwards through the frame and then vertically into the print head, if the frame moves closer to the filament tray, the printing filament is prone to loosening instead of tightening. As a result, the printing filament is prone to knotting or piling up during the process of moving to the print head, which leads to poor subsequent printing results. Utility Model Content
[0005] This invention proposes a 3D printer with a filament guiding function, which solves the problem in the prior art where the printing filament is loose and not tight when the frame moves close to the filament tray, which easily causes the printing filament to tangle or pile up when moving the printing filament.

There are two connecting plates 203, both of which are fixedly mounted on the side of the slide rail 201. The drive screw 204 is rotatably mounted between the two connecting plates 203.

The connecting block 206 is threadedly connected to the drive screw 204, and the side of the connecting block 206 is fixedly connected to the side of the slider 202.
[0029] In this embodiment, reference Figure 4 The feeding assembly includes a connecting rod 301, a fixing plate 302, a consumable tray 303, and a motor 304. There are two connecting rods 301, which are fixedly installed on both sides of the slider 202. There are two fixing plates 302, which are fixedly installed on the two connecting rods 301.

[0031] In this embodiment, reference Figure 5The material feeding assembly includes a mounting rod 501, a stop block 502, a second cylinder 503, and a top block 504.

[0032] It should be added that the side of the stop 502 has a wire groove, and the vertically moving printing consumable slides down along the wire groove of the stop 502. The stop 502 and the top block 504 are at the same horizontal position, and the mounting plate 4 has a sliding groove, in which the top block 504 is slidably installed.
[0033] Working principle: When printing, the printer first winds the printing filament onto the filament tray 303, then passes one end through the slot in the mounting plate 4 and into the print head 2. The print head 2 is then activated, melting the printing filament and ejecting it onto the base plate 1 for printing. During printing, motor 104 is activated, its output driving the reciprocating screw 103 to rotate. This causes the moving frame 3 to move back and forth on the reciprocating screw 103 and the slide rod 102, thereby moving the print head 2 back and forth. Simultaneously, motor 304 is activated, its output driving the filament tray 303 to move between two fixed... The plates 302 rotate, thereby conveying the printing consumables downwards and continuously feeding them into the print head 2. During this conveying process, as the printing consumables wrapped around the consumable tray 303 gradually decrease and move downwards, the second motor 205 can be activated. The output end of the second motor 205 drives the drive screw to rotate between the two connecting plates 203, causing the connecting block 206 to move on the drive screw 204, thereby causing the slider 202 to move left and right on the slide rail 201, which in turn causes the connecting rod 301 and the consumable tray 303 to move, thus ensuring that the downward-moving printing consumables are always vertically positioned directly above the print head 2, preventing the printing consumables from becoming loose or knotted.
[0034] If the printing filament gets tangled during the downward movement, cylinder 2 503 can be activated. Cylinder 2 503 drives the top block 504 to approach the stop block 502, thereby fixing the two sides of the printing filament. Then, motor 304 is activated. The output end of motor 304 reverses, unwinding the loose or excess printing filament onto the filament tray 303 to tighten it, and then it is conveyed again.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
