3D printer heating plate supporting transmission structure

Abstract

The invention discloses a 3D printer heating plate supporting transmission structure which comprises an X-direction supporting transmission device and a Y-direction supporting transmission device. The Y-direction supporting transmission device comprises a chassis, two Y-direction linear guide rails arranged on the chassis, Y-direction sliding blocks matched with the Y-direction linear rails and a Y-direction belt pulley transmission mechanism driven by a Y-direction stepping motor. The X-direction supporting transmission device comprises a supporting frame, two X-direction linear guide rails arranged on the supporting frame, X-direction sliding blocks matched with the X-direction linear guide rails, a heating plate supporting a printer heating platform and an X-direction belt pulley transmission mechanism driven by an X-direction stepping motor. The heating plate is arranged on the X-direction sliding blocks, and the supporting frame is arranged on the Y-direction sliding blocks. According to the 3D printer heating plate supporting transmission structure, the movement of the heating plate in the X-axis direction and the movement of the heating plate in the Y-axis direction are completely independent and do not affect each other, displacement compensation between the X-axis direction displacement and the Y-axis direction displacement of the heating plate do not need to be computed, and post processing processes of data are simplified.

Description

(1) Technical field: [0001] The invention relates to the internal structure of a printer, in particular to a 3D printer heating plate supporting transmission structure. (2) Background technology: [0002] At present, the structure used to support and drive the heating plate of a 3D printer generally adopts a cylindrical slide rail support and screw drive system. [0003] As a support structure, cylindrical slides have many disadvantages. For example, cylindrical sliding rails generally adopt a fixing method with two ends fixed, and two parallel rails are often used as a whole, and the two cylindrical sliding rails must be completely parallel to ensure accuracy. This places high requirements on the positioning of the four fixed points for fixing the two slide rails, which makes it difficult to ensure the accuracy of the system and increases the difficulty of installation. [0004] Another disadvantage of the above structure is that once the two cylindrical slide rails are installed,...

Problems solved by technology

This places high requirements on the positioning of the four fixing points that fix the two slide rails, and it is difficult to ensure the accuracy of the system, which increases the difficulty of installation.

[0004] Another disadvantage of the above structure is that once the two cylindrical slide rails are installed, it is inconvenient to disassemble, which is not conducive to the maintenance and upgrading of the machine in the later period

[0005] Another disadvantage is that the cylindrical slide rail is used as the support structure of the heating plate, and when the heating plate slides, it will inevitably produce a large noise

[0006] The transmission structure of the screw has some of the disadvantages mentioned above, and also has its own inconveniences: for example, the transmission efficiency is low, the friction coefficient of the screw itself is large, and the rotation rate is limited, which reduces the work of the entire mechanical system. efficiency
