Embodiment Construction

[0037] Such as figure 1 As shown in -11, the present invention discloses a device including a mounting frame 1, an extruding device, a displacement device and a processing platform 4. The displacement device is arranged on the mounting frame 1 and drives the extrusion device along the horizontal, vertical and horizontal directions relative to the mounting frame 1. Move vertically, the processing platform 4 is set on the installation frame 1 and is located below the extrusion head, the extrusion device includes an extrusion support 2, a heating mechanism 21 and an extrusion pipeline 22, and the extrusion pipeline 22 is vertically arranged on the extrusion support 2, The extrusion pipe 22 is provided with an extrusion passage for the linear printing material to pass through. The heating mechanism 21 is arranged around the lower end of the extrusion pipe 22. The extrusion pipe 22 is provided with a cooling mechanism 23 for cooling the printing material in the pipe. The cooling me...

Abstract

The invention relates to a 3D printer. The 3D printer comprises an installation frame, an extrusion device, a displacement device, a discharge device and a processing platform. The discharge device comprises a wire outlet installation base, an upper wire outlet pipeline, a lower wire outlet pipeline, a wire outlet motor, a wire outlet driving wheel and a wire outlet auxiliary wheel. A wire conveying cavity is formed by the peripheral face of the wire outlet driving wheel and the peripheral face of the wire outlet auxiliary wheel. The wire outlet auxiliary wheel is in running fit with the wire outlet installation base. The wire outlet motor drives the wire outlet driving wheel to rotate. The upper wire outlet pipeline and the lower wire outlet pipeline are used for allowing printing materials to penetrate and are vertically and sequentially arranged on the wire outlet installation base. A wire conveying partition is arranged between the upper wire outlet pipeline and the lower wire outlet pipeline. The position of the wire conveying partition corresponds to the position of the wire conveying cavity. A swing arm is arranged on the wire outlet installation base. An adjustment bolt is arranged on the swing arm in the swinging direction. An adjustment nut limited to the end face of the other end, relative to the swing arm, of the wire outlet installation base and a limiting clamping ring limited to the end face of the other end, relative to the wire outlet installation base, of the swing arm are arranged on the adjustment bolt. Due to the adoption of the scheme, the 3D printer which is stable in printing material discharge is provided.

Description

technical field [0001] The invention relates to a printing device, in particular to a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on digital model files and uses special wax, powdered metal or plastic and other bondable materials. By printing layers of adhesive materials to create three-dimensional objects, it is widely used in the manufacture of products at this stage. [0003] The existing 3D printer includes a mounting frame, an extrusion device, a displacement device and a processing platform. The displacement device is arranged on the mounting frame and drives the extrusion device to move horizontally, vertically and vertically relative to the mounting frame. The processing platform is arranged on the mounting frame. And located under the extrusion head, wherein the extrusion device includes an extrusion support, a...
