[0014] Figure 2 yes Figure 1 Schematic diagram of the structure after the filter box in is flipped 180 degrees. DETAILED DESCRIPTION

[0015] Combine the following Figure 1-2 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The isostatic graphite powder automatic maintenance and screening device shown includes: a screening frame 3, a powder qualified product hopper 1, a powder rework hopper 2 and a motor 8. The powder qualified product hopper 1 is arranged on one side of the powder rework hopper 2. A connecting plate 9 is arranged between the powder qualified product hopper 1 and the powder rework hopper 2. The connecting plate 9 can be welded and fixed, thereby improving the relative position stability between the powder qualified product hopper 1 and the powder rework hopper 2.

[0017] The screening frame 3 is flippably arranged above the qualified powder product hopper 1. In the present embodiment, a screen 5 is arranged at the bottom of the screening frame 3, and a vibration generator 4 is arranged at the side of the screening frame 3. After the powder is introduced into the screening frame 3, the vibration of the screening frame 3 is utilized for screening, and the qualified powder falls into the qualified powder product hopper 1 below for collection.

[0018] like Figure 2 As shown, a first pin seat 14 is provided on one side of the screening frame 3 adjacent to the connecting plate 9, a second pin seat 12 is provided on the connecting plate 9, and a pin shaft 13 penetrating the second pin seat 12 is provided in the first pin seat 14 to support the flipping of the screening frame 3. After screening for a certain period of time, the screening frame 3 is flipped 180 degrees and transferred to the top of the powder rework hopper 2, and the powder particles with larger particle sizes retained in the screening frame 3 are transferred to the powder rework hopper 2, avoiding the problem of screen blockage and realizing automatic cleaning and maintenance.
