Problems solved by technology

However, the above-mentioned multi-nozzle solution has the problem of relatively complicated control. For example, to control multiple nozzles to work at the same time, it is necessary to independently control the supply of each nozzle. With the increase of nozzles, existing general control chips, such as STM32 The series of single-chip microcomputers have the problem of insufficient output channels, and the multi-chip solution involves the coordination of each chip
Moreover, in the process of programming the control software, due to the problem that the working range of each nozzle must overlap with each other, the division of each part needs to be redesigned according to different parts, and the control is difficult, especially for each different part. Write control software or need more setting parameters, which affects work efficiency and puts higher demands on operators

Embodiment 1

[0033] like Figures 1~5 Among them, a multi-nozzle 3D printing system includes a bracket 1, a nozzle bracket 13 is movably connected to the bracket 1, the nozzle bracket 13 and the bracket 1 are relatively reciprocated along the Y direction, one end of the line feed cylinder 8 is connected to the nozzle bracket 13, and the other end is connected to the nozzle bracket 13. Connect with bracket 1;

[0034] The nozzle bracket 13 is provided with a plurality of X-direction trolleys 4 running along the X-axis, and each X-direction trolley 4 is provided with a nozzle 6, and the nozzle 6 and the X-direction trolley 4 reciprocate relatively along the Y-direction. With this structure, each nozzle 6 in the multi-nozzle structure has an independent Y-direction drive. Compared with the scheme of sharing the Y-direction drive, each nozzle 6 can be as Image 6 As shown in the figure, the graphics in the block area of ​​A1~A6 are completed separately, unlike the scheme of sharing the Y-dire...

Embodiment 2

[0052] On the basis of Embodiment 1, the scheme of 6 groups of nozzles 6 is used for description in this example. In this example, at least 7 main control chip schemes are adopted, all of which use STM32F series chips. like Figure 7 As shown in the figure, one of them is used as the master chip, and the other 6 are used as slave chips. The master chip is used to send the cut graphics to each slave chip, and to control the Z-direction motor 2 and the line feed cylinder 8. The slave chip is used to control the X-direction motor 5 and the Y-direction motor 42. The control program of each slave chip is exactly the same as the control program in the prior art, and only the part of the cutting pattern of the master chip needs to be set. It is very convenient to set up and operate, and the requirements for the operator are not high. First, input the workpiece graphics to the main control device, and the main chip of the main control device divides each layer of the workpiece graphi...

Abstract

The invention provides a multi-nozzle 3D printing system, comprising a bracket, the nozzle bracket and the bracket are movably connected, the nozzle bracket and the bracket are relatively reciprocated along the Y direction, one end of the line feed cylinder is connected with the nozzle bracket, and the other end is connected with the bracket; the nozzle bracket; There are a plurality of X-direction trolleys running along the X-axis, and each X-direction trolley is provided with a nozzle, and the nozzle and the X-direction trolley move relatively reciprocatingly along the Y-direction. By setting up multiple X-direction trolleys, and setting each X-direction trolley with a nozzle that can reciprocate along the Y-direction, with a nozzle bracket that can switch positions, it can greatly reduce the difficulty of control while improving work efficiency. Control method It is basically the same as the usual single nozzle solution, which can reduce the requirements for operators. The solution of the present invention enables each nozzle to have an independent Y-direction drive, which can greatly improve the processing efficiency compared with the solution of sharing the Y-direction drive.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a multi-nozzle 3D printing system. Background technique [0002] 3D printing has been widely used as a forming technology for small batch parts. It uses a nozzle to heat the filament and spray it out, and stack it layer by layer to realize the forming of 3D parts. Existing 3D printing has the problem of taking a long time. In order to overcome this problem, the prior art proposes a multi-nozzle printing solution to shorten the printing time, for example, a multi-nozzle structure 3D printer and a printing method thereof described in Chinese patent document CN111619113A. CN111376478A A device for calibrating the relative coordinates of the discharge port of a multi-nozzle 3D printer. However, the above-mentioned multi-nozzle solution has the problem of complicated control. For example, to control multiple nozzles to work at the same time, it is necessary to control the feeding of each ...
