Embodiment

[0013] like figure 1 As shown, a feed throat, the feed throat is a hollow structure, the feed throat includes a feed throat mouth 1, the feed throat inner wall 2 and is arranged on the feed throat outer wall and is used for The feeding thread 3 fixed with the heating aluminum block, the inner wall 2 of the feeding throat is provided with a Teflon tube 4 or the inner wall 2 of the feeding throat is coated with a Teflon coating. The feed throat opening 1 includes an outer opening and an inner opening, the diameter of the outer opening is greater than that of the inner opening, and the inner opening coincides with the opening of the Teflon tube 4 .

[0014] Specific work engineering:

[0015] like figure 1 As shown, after the printing filament enters from the feed throat, it continues to be transported along the Teflon tube. The non-stick and sliding properties of the Teflon tube can greatly reduce the friction between the printing filament and the inner wall of the feed throat...

Abstract

The invention relates to a feeding throat pipe, in particular to a feeding throat pipe of an FDM type 3D printer, and belongs to the field of office supplies. The feeding throat pipe is of a hollow structure and comprises a feeding throat pipe opening, a feeding throat pipe inner wall and feeding threads which are arranged on a feeding throat pipe outer wall and are used for being fixed on a heating aluminum block. A Teflon pipe is arranged on the feeding throat pipe inner wall in a tight-attaching mode, or a Teflon pattern layer is arranged on the feeding throat pipe inner wall in a coating mode. According to the feeding throat pipe, the Teflon pipe or the Teflon pattern layer are added on the inner wall to lubricate the inner wall, the lubricating effect of the Teflon pipe is used for reducing friction force between printing filament materials and the feeding throat pipe inner wall as much as possible, so that filament outputting is smooth, and filament blocking cannot happen easily. The feeding throat pipe is simple in structure, easy to manufacture and great in using effect.

Description

technical field [0001] The invention relates to a feeding throat, in particular to a feeding throat of an FDM 3D printer, belonging to the field of office supplies. Background technique [0002] Filamentous material selective cladding (Fused Deposition Modeling) rapid prototyping process is a kind of rapid prototyping process that does not rely on laser as the molding energy, but heats and melts various filaments, such as engineering plastics ABS, polycarbonate PC, etc. method, referred to as FDM. [0003] The desktop FDM 3D printer has high printing accuracy, and its appearance is relatively small, which is easy to carry and install. The most important thing is that the manufacturing cost of this 3D printer is low, which is affordable by ordinary families. However, the existing FDM3D printers cannot solve the problem well When printing, the problem of wire blocking. Contents of the invention [0004] The present invention designs a feeding throat, and its purpose is ...
