Clearing device capable of automatically stretching in nozzle of 3D printer

Abstract

The invention relates to the technical field of intelligent office cleaning, and discloses a clearing device capable of automatically stretching in a nozzle of a 3D printer. The device comprises a nozzle, a heating head and a throat pipe, wherein a cooling liquid storage pipe is arranged in the middle of the interior of a shell, a rotary table is fixedly connected to the front end of the cooling liquid storage pipe, a sealing ring is fixedly connected to the top end of the rotary table, a push rod is arranged at the tail end of the shell and extends into the shell, a motor is arranged at the front end of the push rod, a cleaning rotating pipe is fixedly connected to the top end of the sealing ring and extends to the tail end of the sealing ring, and barb devices are arranged on the surfaceof the cleaning rotating pipe. The cleaning rotating pipe, the push rod and the barb devices are arranged, so that the effect of directly clearing impurities without device dismounting is achieved, the clearing device is more convenient to use, and due to arrangement of barbs, the springs and the motor structure, the purposes of freely stretching and clearing in the nozzle and achieving the better cleaning effect are realized.

Description

technical field [0001] The invention relates to the technical field of intelligent office cleaning, in particular to a cleaning device that can automatically expand and contract in the nozzle of a 3D printer. Background technique [0002] 3D printing technology is a printing technology that has gradually become popular in recent years. It has played a very good role in various fields of life and work, especially in some aspects of shape creation. Some original industrial designs and models are in the It used to take a long time to make it, but using 3D printing technology to model the design, it only takes a few days to print the model, which greatly saves costs and improves speed. [0003] A 3D printer will melt and extrude hundreds of kilograms of material during its service life, and all the material will be extruded from the nozzle, and the diameter of the nozzle is small, and it will be clogged after a long time, making the extrusion of the nozzle There are many reason...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cleaning device that can automatically expand and contract in the nozzle of the 3D printer. After the printer heats the nozzle, insert the cleaning device into the nozzle, and set barbs and springs on the surface of the cleaning tube. Under the action of centrifugal force, the cleaning position is changed by the expansion and contraction of the spring in the nozzle. It has the advantages of no need to disassemble the nozzle, easy to use, and good cleaning effect, which solves the problems of troublesome disassembly of the nozzle and poor cleaning effect.
