Cleaning device for FDM process extrusion wheel

Abstract

The invention relates to the technical field of FDM printing, in particular to a cleaning device for an FDM process extrusion wheel. The cleaning device comprises a base shell and feeding ports, two sets of limiting wheels are arranged in the base shell, driving wheels are rotationally installed on the side edges of the limiting wheels, a motor is installed outside the base shell and connected with the driving wheels, and the feeding ports are correspondingly formed in the top face and the bottom face of the base shell. And a cleaning assembly is rotationally mounted in the base shell and located on the side edge of the driving wheel, and the driving wheel at the bottom is connected with the cleaning assembly through a linkage assembly. Through linkage of the linkage assembly, the cleaning assembly is driven to rotate when the driving wheel moves, surface cleaning of the driving wheel is achieved, and the situation that discharging is not smooth due to the fact that the bite force of the driving wheel is reduced due to chipping adhesion is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of FDM printing, in particular to a cleaning device for an extrusion wheel of an FDM process. Background technique [0002] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and is gradually used for the direct manufacturing of some products. There are already parts printed using this technology. [0003] The extruder of the FDM printing equipment plays a driving role in the wire rod. Now all the extruders of the FDM process on the market, the extrusion wheel part, has not had any cleaning device for the extrusion part, and the extrusion wheel and the wire rod are constantly Friction, the extrusion wheel is covered with scraps of material. As the printing time goes on, the bite force between the extrusion wheel and the wire keeps decreasing, resulting in discontinuous extrusion. Therefore,...

Problems solved by technology

[0003] The extruder of the FDM printing equipment plays a role in driving the wire. Now all the extruders of the FDM process on the market, the extrusion wheel part has no cleaning device for the extrusion part. The extrusion wheel and the wire are constantly friction, the extrusion wheel is covered with material debris, and as the printing time continues, the bite force between the extrusion wheel and the wire continues to decrease, resulting in discontinuous extrusion. Therefore, it is necessary to provide a new The cleaning device of the FDM process extrusion wheel solves the above technical problems
