3D printer with automatic clearing function

Abstract

The invention relates to the technical field of printer equipment, in particular to a 3D printer with an automatic clearing function. The 3D printer aims at solving the technical problems that an error is generated between the initial glue spraying moment of a nozzle and a program setting moment due to the fact that glue stock on the nozzle of an existing device is easily blocked, vibration is generated due to high-pressure release at the beginning moment of glue spraying, the quality of printing operation products is affected, waste is inconvenient to collect, clearing and maintenance are troublesome, and in order to solve the technical problem, the 3D printer with the automatic clearing function comprises a bearing arm, and the bearing arm is of a U-shaped structure. Through arrangement of a claw head and a scraping block, a moving plate and a bearing plate are driven by a step change device to generate separation action, so that the scraping block performs scraping action along the glue stock on the outer surface of the nozzle, blockage is avoided, stable and reliable operation is guaranteed, a piston plate instantly moves on the inner side of the piston pipe, negative pressure is generated at the position of an air inducing hole, and the scraped glue stock is collected.

Description

technical field [0001] The invention relates to the field of printer equipment, in particular to a 3D printer with an automatic cleaning function. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct by layer-by-layer printing. object technology. [0003] In the existing 3D printing process, rubber is widely used as a material with low cost, easy acquisition and high plasticity. [0004] In the process of implementing the prior art, the inventors found that the existing 3D printers have at least the following problems that have not been resolved: 1. The existing device tends to leave little glue on the surface of the hole on the bottom side of the nozzle after the glue spraying is completed, causing the nozzle to be blocked. , and in the next printing job, the initial time of nozzle glue ou...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a 3D printer with an automatic cleaning function, which solves the problem that the glue material of the nozzle of the existing device is easily clogged, which causes an error between the initial time of spraying the nozzle and the time of the program setting, and causes the error to occur during the glue spraying. At the beginning, vibration is generated due to the release of high pressure, which affects the quality of printing products, inconvenient collection of waste materials, and troublesome cleaning and maintenance.
