Single-motor double printer head 3D printer head mechanism

Abstract

The invention discloses a single-motor double printer head 3D printer head mechanism and belongs to the field of printing devices. The purpose is to provide the single-motor double printer head 3D printer head mechanism which can perform bi-color printing through double printer heads driven by one motor. The motor is installed on a headstock, a driving gear is installed on a motor shaft of the motor and meshed with a left big gear and a right big gear, and a left gear shaft of the left big gear and a right gear shaft of the right big gear are fixed on the headstock; a triangular support is installed at the front end of the motor shaft, a left idle wheel and a right idle wheel are installed on the triangular support, a left clamping wheel is installed on the left big gear, a right clamping wheel is installed on the right big gear, and filaments pass through the space between the right idle wheel and the right clamping wheel and then enter throat tubes of the upper ends of the printer heads, and a support is installed between the bottom of the triangular support and the top of one printer head. The structure is compact and reasonable, operation is convenient and fast, people easily get the hang of the single-motor double printer head 3D printer head mechanism, the structure of one motor and the double printer heads is adopted, in other words, one motor is used for respectively controlling the two printer heads to work in a triangular support linkage mode, and therefore good conditions are created for the bi-color printing.

Description

technical field [0001] The invention belongs to the field of printing equipment. Background technique [0002] The printing equipment for printing 3D images is gradually recognized by people, and gradually widely used in various industries. The existing 3D printers are basically single-color, single-motor, and single-nozzle. When printing more than two colors, multiple printers need to be exchanged. It is very cumbersome. Correspondingly, there is a two-color 3D printer for printing. However, it uses two motors and two nozzles. If the weight of the nozzle is increased, it will cause vibration, which will not only affect the printing quality, but also slow down the printing speed. [0003] Take desktop 3D printers as an example: In the hot 3D market, there are various types of desktop 3D printers, whether domestic or foreign, but the structure of the "heart" nozzles is similar. The structure of traditional 3D printer nozzles is double motors and double nozzles (the motor is...

Problems solved by technology

The structure of traditional 3D printer nozzles is double motors and double nozzles (the motor is 42 motors), that is, two motors and two nozzles, and each motor drives and controls one nozzle to work independently. The weight of a single motor is about 235g, and the weight of a double motor It is conceivable that it is a bit bulky, and during the printing process, the torque output by the 42 motors is much greater than the torque required for actual wire feeding, resulting in a large torque waste; two 42 motors that are slightly bulky fixed on the base are enough Limit the printing speed, and at the same time, the fixed nozzle (cannot be lifted) also leaves hidden dangers for printing multi-color
