A new type of wire feeder with automatic material change and continuous printing

Abstract

The invention provides a novel wire feeding machine achieving automatic material replacing and continuous printing of material breakage. The novel wire feeding machine achieving automatic material replacing and continuous printing of material breakage comprises a motor, a wire feeding wheel installing plate, a bearing installing plate and a fixing plate which are sequentially arranged; the four portions are connected in a detachable manner; an output shaft of the motor is sleeved with a gear; a gear penetrate-out hole is formed in the wire feeding wheel installing plate which is further provided with an upper wire feeding wheel and a lower wire feeding wheel; the gear is engaged with the upper wire feeding wheel and the lower wire feeding wheel; a wire feeding channel, an upper wire feeding wheel containing hole, a lower wire feeding wheel containing hole, an upper installing groove and a lower installing groove are formed in the bearing installing plate, and the upper wire feeding wheel containing hole and the lower wire feeding wheel containing hole are located in one side of the channel, and the upper installing groove and the lower installing groove are located in the other side of the channel; the wire feeding channel is divided into an upper segment and a lower segment; and the channel upper segment is communicated with the upper installing groove and the upper wire feeding wheel containing hole and can contain a plurality of wire materials side by side at the same time. By means of the novel wire feeding machine achieving automatic material replacing and continuous printing of material breakage, when the wire materials are used up or because of accidental wire breakage, continuous printing cannot be performed, it is not needed to temporarily stop the printing process, and manual material replacing is not needed.

Description

technical field [0001] The invention relates to a three-dimensional printer based on FDM fused deposition manufacturing technology, in particular to a new type of wire feeder for automatic material change and continuous printing when material is cut off. Background technique [0002] Three-dimensional printing technology began in the mid-1990s. According to different printing materials and molding methods, it can be divided into many types. Among them, Fused Lamination Modeling (FDM), that is, fused deposition 3D printing technology, has a simple structure, so The use of materials is easy to obtain, many advantages such as low manufacturing cost, are widely used. The 3D printer using fused lamination molding technology (FDM) heats and melts the filamentary hot-melt material, and at the same time, under the control of the computer, the 3D nozzle selectively coats the material on the workbench according to the cross-sectional profile information. After rapid cooling, a layer ...
