▎ 摘　　要

NOVELTY - The device has a fixing plate (14) whose upper end is fixedly installed with a loading plate (15) through a connecting column (16). The side of the fixing plate is fixedly connected with a first connecting plate (17). One end of the first connecting plate is fixedly connected with a second connecting plate. An electric push rod is fixedly installed on one side of the second connecting plate. One end of the piston rod of the electric push rod is fixedly connected with a box case (19). A second screw rod is rotatably installed inside the box case. A third connecting plate is fixedly installed on one side of the second screw rod screw seat. An air outlet is fixedly installed at the lower end of the third connecting plate. One side of the box case is provided with a first through hole (21). The air outlet is located inside the first through hole. USE - Quick freezing device for graphene three-dimensional (3D) printer. ADVANTAGE - The temperature of the product during the product printing process is reduced, the forming speed of the product is accelerated, the product is not easy to deform in the printing process, the quality of the product is improved to a certain extent, and does not need to independently cool the product after printing. The working efficiency is improved to a certain extent. The working intensity of the worker is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the quick freezing device for graphene 3-D printer.
