Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a consumable material selector for multi-color material replacement. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. The 3D printer used is also called a three-dimensional printer, which is a rapid prototyping process equipment, and multi-color printing is an inevitable direction of the development of 3D printers.

[0003] The multi-color schemes of existing fused filament manufacturing 3D printers are mostly multi-input and one-output, that is, multiple color filaments enter the printing nozzle from different channels and are ejected from one nozzle. In the multi-input and one-output multi-color printing mode, since multiple materials are extruded through a single nozzle, the nozzle needs to be cleaned when replacing different color materials to avoid color contamination. Therefore, there are problems such as affecting printing quality and printing efficiency. For this reason, we propose a consumables selector for multi-color material replacement.

[0007] Furthermore, the print head is connected to the inner wall of the bottom end of the material box through a thread, and the print head and the material box are connected through a pipe.

[0008] Furthermore, the material box forms a rotating structure through an axle frame and an outer frame, and the bottom end of the axle frame is sleeved on the axis of the pile frame.

[0009] Furthermore, the main body includes a main frame, and bases are distributed on both sides of the bottom end of the main frame, the bottom end of the base is connected to a cylinder frame, and the inner walls on both sides of the main frame are connected to guide rail frames, and the middle part of the guide rail frame is sleeved with a connecting frame.

[0010] Furthermore, the bottom end of the main frame is fixedly connected to the base, and the cylinder frame is connected to the base via screws around the periphery.

[0011] Furthermore, the connecting frame includes a guide rail block, and the guide rail frame is fitted around the inner wall of the guide rail block, a connecting plate is provided on one side of the guide rail block, and a sliding groove is opened on the outer wall of the connecting plate, a sliding block is provided on the inner wall of the sliding groove, and the outer wall of the sliding block is connected to a buckle plate.

[0012] Furthermore, the connecting plate is slidably matched with the guide rail frame through the guide rail block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The consumables selector uses a disc-shaped outer frame to store multiple groups of consumables of different colors in the form of a material box, so that they are integrated inside the outer frame. The user can select the required color consumables by rotating the shaft frame and cooperating with the material selection port for connection and use. The print head is connected and removed from the material box and docked with the material rack, so that it can be quickly put into use, saving preparation process and improving printing efficiency.

[0015] In order to maintain the stability of this structure when applied to the printer structure, this consumables selector uses the main frame of the gantry structure as the mounting frame, and forms a longitudinal sliding during the printing process through the base and cylinder frame on both sides of the bottom. At the same time, the guide frame is connected through the main frame to provide a stable mounting structure for the connection frame and the material frame.

[0016] In order to maintain stability and convenience when replacing consumables, this consumable selector has a connecting plate on one side of the guide block, so that its slider cooperates with the buckle plate to place the separated print head. The inner walls of the two sets of buckle plates are attached with soft rubber blocks, which can buckle the engaged print head stably, making the print head placement and removal process convenient and stable, and put into use more quickly.
