Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a material tray structure of an FDM printer. Background Art

[0002] FDM printer is a kind of 3D printer. The material of FDM is generally thermoplastic material, such as wax, ABS, nylon, etc., which is fed in filament form. The material is heated and melted in the nozzle. The nozzle moves along the cross-sectional contour and filling trajectory of the part, and the molten material is extruded at the same time. The material solidifies rapidly and condenses with the surrounding material.

[0003] The material tray of a conventional 3D printer is usually connected by bolts. Replacing the material tray requires re-disassembly, which is troublesome to operate. In addition, there are problems such as poor positioning accuracy and large feeding resistance. Long-term use will reduce the working performance of the 3D printer's wire feeding mechanism.

[0012] Beneficial effects of the utility model:

[0013] By setting a fixed structure, when in use, the raw material tray is inserted into the clamping rod, and then the connecting frame is sleeved on the supporting rod. The clamping groove on the limit plate below the connecting frame will be connected with the clamping rod, thereby limiting the raw material tray, and at the same time, the fixing plate is pressed to allow it to enter the fixed groove block. After it is fully entered, the clamping spring will push the fixing plate back to its original position, thereby fixing the connecting frame to the supporting rod, so that the device can easily disassemble the raw material tray and facilitate the loading of the raw material tray.

[0014] By setting up a rotating motor, when in use, the raw material line on the raw material tray is connected to the inside of the printer body through the first pulley member and the second pulley member. When the printer body starts working, the rotating motor is started to drive the raw material tray to operate synchronously through the clamping rod, so as to avoid the raw material line from getting stuck when entering the printer body, so that the device can reduce the resistance during feeding and make the device safer when in use.
