AI Technical Summary

Technical Problem

In existing photopolymer 3D printing equipment, the adjustment of the liquid level in the material tank relies on manual intervention, which leads to high labor intensity for operators, making it difficult for them to adapt to long-term continuous printing, thus affecting printing accuracy and continuity.

Method used

A liquid level control device including a follow-up mechanism, an adjustment mechanism, and a feeding mechanism was designed. By sensing changes in the liquid level, the device automatically adjusts the liquid level in the tank and links the feeding mechanism to achieve automatic feeding, thus maintaining a stable liquid level.

Benefits of technology

It achieves automated control of the material tank level, reduces manual intervention, adapts to long-term continuous printing, improves printing accuracy and production efficiency, and reduces the labor intensity of operators.

Abstract

The utility model relates to 3D printing technical field, concretely for a kind of liquid level control device for photocuring 3D printing equipment, including trough, follow-up mechanism, adjusting mechanism, make-up pipe and make-up mechanism;Trough side wall is provided with communicating pipe, the inlet of communicating pipe is communicated with the bottom of trough side wall;Follow-up mechanism is arranged at one side of trough, and one end of follow-up mechanism is communicated with trough by communicating pipe;Adjusting mechanism is arranged at one side of trough for adjusting the height of liquid level in trough, and one end of follow-up mechanism extends into adjusting mechanism;Make-up pipe is arranged in trough;Make-up mechanism is arranged at one side of trough, and the discharge end of make-up mechanism is communicated with adjusting mechanism.The utility model is set up by the cooperation between follow-up mechanism, adjusting mechanism and make-up mechanism, device can automatically maintain the stable liquid level in trough, avoid that printing layer and trough wall are adhered due to liquid level being too high, or the defects such as printing layer material shortage, fault are caused by liquid level being too low.
