Printing nozzle convenient to replace for 3D printer

Abstract

The invention discloses a printing nozzle convenient to replace for a 3D printer, comprising a mounting plate. A first motor and a second motor are mounted on the two sides of the top surface of the mounting plate, respectively; the first motor is in key connection with a first gear through an output shaft; the second motor is in key connection with a second gear through an output shaft; the firstgear and the second gear are both arranged in the mounting plate; the interior of the mounting plate is slidably connected with a first rack and a second rack; and the first rack is connected with the side wall of the first gear in an engaged manner. The invention aims to provide a printing nozzle convenient to replace for a 3D printer; by controlling the first motor and the second motor to rotate forwards and backwards, the first rack and the second rack move in the mounting plate, and then, a first limiting block and a second limiting block are clamped and unclamped, so that mounting and dismounting of the printing nozzle are completed conveniently.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an easy-to-replace print nozzle for a 3D printer. Background technique [0002] 3D printer print head is an accessory for 3D printers. Its main function is to manufacture three-dimensional objects by printing layers of adhesive materials by using special wax, powdered metal or plastic and other adhesive materials. It is an indispensable device in existing 3D printing. [0003] However, common printing nozzles have certain disadvantages. Common 3D printing nozzles are often inconvenient to replace during use. When replacing printing nozzles, it is often time-consuming and laborious, and the delay is long, which affects printing efficiency. And because 3D printing materials are often It is a material that solidifies quickly. If it takes a long time to replace the 3D printing nozzle, it will often have a certain impact on the printed product. Contents of the invention [000...
