Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a be used for 3D to print automatic leveling device, includes printer main part 1, the feed tray end 2, prints board 4 and levelling mechanism 5, including elevating system 3 on the 1 vertical face of printer main part, elevating system 3's lift portion is connected with prints board 4 and drives and goes up and down, printer main part 1's horizontal plane is including being provided with the feed tray end 2, the levelling mechanism 5 that has a plurality of upper and lower contractions is dismantled respectively to the bottom both sides of the feed tray end 2, print board 4 descends to exert pressure at the feed tray end 2, and the feed tray end 2 transmits for levelling mechanism 5 contractions, realizes printing board 4 and the feed tray end 2 pastes tightly and parallel.
