Abstract

The invention provides an extrusion device of a 3D printing pen. The extrusion device comprises an extrusion cylinder arranged between a penholder and a pen nozzle. An extrusion chamber is formed in the extrusion cylinder, communicates with the pen nozzle, and is internally provided with a heater for fusing a pen core and a spiral conveying assembly for conveying the fused pen core. The spiral conveying assembly comprises a rotating shaft and spiral blades arranged on the rotating shaft. One end of the rotating shaft extends into the pen nozzle, and the other end of the rotating shaft is connected to a motor located outside the extrusion chamber through a connecting rod. The motor is fixed in the penholder through a support. According to the invention, firstly the heater is utilized to heat and fuse the pen core; then the spiral blades are driven by the motor to convey the fused pen core to the pen nozzle; and finally the fused pen core is extruded from the pen nozzle. The extrusion device of the 3D printing pen is simple in structure, ingenious in design, and stable and reliable in effect, and is easy to carry out.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to an extrusion device for a 3D printing pen. Background technique [0002] 3D printing, also known as rapid prototyping, is a new type of industrial processing technology. For plastic materials, the principle of 3D printing is generally to melt the plastic and then spray it out. The sprayed material is cooled and solidified to form the desired shape. 3D printing systems for industrial processing are complex. The principle of 3D printing is applied to the paintbrush with a small structure, so that the paintbrush can realize the simple 3D printing function. The 3D printing pen not only increases the interest of the brush product, but also assists the design performance of the designer. However, since the internal space of the 3D printing pen is small, it is very important to design an extrusion device that has a simple structure and can satisfy a good extr...
