[0017] Figure 3 yes Figure 1 A schematic diagram of the structure after the cover plate is lowered. Detailed Implementation

[0018] The following is combined with Figures 1 to 3 The technical solution of this utility model will be further illustrated through specific embodiments.

[0019] like Figure 1 The isostatic graphite impregnation apparatus shown is used for impregnating isostatic graphite plates 22. It includes a workbench 11, an impregnation tank 1, a cover plate 2, a support 3, a roller 15, and a ball bearing retainer 9. The impregnation tank 1 is mounted on the workbench 11 and extends downwards. An inlet valve 12 is located on the upper side of the impregnation tank 1, connected to an impregnation liquid pipe, allowing the impregnation liquid to be introduced into the impregnation tank 1. A drain valve 13 is located at the bottom of the impregnation tank 1 to control the discharge of the impregnation liquid, facilitating cleaning of the impregnation tank 1 after impregnation production.

[0020] The cover plate 2 is vertically and flexibly positioned above the impregnation tank 1. In this embodiment, the workbench 11 is provided with guide columns 8 located on both sides of the impregnation tank 1 and extending upward through the cover plate 2 to guide the lifting and lowering of the cover plate 2. A fixing plate 6 is provided at the top of the guide column 8, and a hydraulic cylinder 6 connected to the cover plate 2 is provided on the fixing plate 6. The hydraulic cylinder 6 can be controlled by a solenoid valve to extend and retract, driving the lifting and lowering of the cover plate 2.

[0021] like Figure 1 As shown, a flange 14 is provided around the top edge of the impregnation tank 1 on the workbench 11, and a sealing ring 7 corresponding to the flange 14 is provided at the bottom of the cover plate 2. Figure 2 As shown, the sealing ring 7 descends with the cover plate 2 and contacts the flange 14, thus sealing the impregnation tank 1. A vacuum pipe connector 21 is provided on the cover plate 2. The vacuum pipe connector 21 is connected to an external vacuum pump, which can be used to evacuate the impregnation tank 1 to ensure the impregnation effect of the isostatic graphite plate 22.

[0022] The bracket 3 is positioned at the bottom of the cover plate 2 and points downward toward the impregnation tank 11. The bracket 3 can be fixed to the bottom of the cover plate 2 with screws and moves up and down with the cover plate 2. Several horizontally spaced and upwardly extending guide grooves 4 are recessed at the bottom of the bracket 3 to limit the left and right movement of a single isostatic graphite plate 22.

The cover plate 2 drives multiple isostatic graphite plates 22 to descend synchronously into the impregnation tank 1. Figure 2 As shown, this improves impregnation efficiency, and the small contact area between the roller 15 and the ball bearings 10 and the isostatic graphite plate 22 reduces the coverage of the isostatic graphite plate.

[0026] like Figure 1As shown, one end of the roller 15 is provided with a first sprocket 16, the vertical plate 17 is provided with a motor 19 above the first sprocket 16, the rotating shaft of the motor 19 is provided with a second sprocket 20 corresponding to the first sprocket 16, and the first sprocket 16 and the second sprocket 20 are provided with a chain 18, so as to indirectly drive the roller 15 by the motor 19, the motor 19 can be controlled by PLC to rotate reciprocatingly at a small angle, drive the roller 15 to rotate reciprocatingly, drive the longitudinal micro-motion of the isostatic pressure graphite plate 22, further reduce the coverage of the roller 15 and the ball 10 on the isostatic pressure graphite plate 22, and ensure the comprehensiveness of the surface impregnation of the isostatic pressure graphite plate 22.
