[0002] In the production of molybdenum slabs, a certain mass of molybdenum powder needs to be filled into rubber molds according to the required density and then pressed using an isostatic press. The current production process involves manually placing a rubber sleeve into a steel sheath to prevent deformation, then weighing a certain mass of molybdenum powder and filling it into the rubber sleeve in stages. During filling, the molds need to be continuously shaken to compact the powder and ensure the required density is achieved. This filling method easily causes dust to fly around, and inhaling the extremely fine molybdenum powder can harm human health. Furthermore, it requires at least two people working together, and the compaction process is very physically demanding. Utility Model Content

[0022] The weighing hopper and guide hopper mechanism includes two sets of tiltable weighing hoppers 6, each located below two vibrating feeders 5. A weighing sensor 7 is positioned below each weighing hopper 6, and the weighing sensor 7 and weighing hopper 6 are mounted on a sensor mounting plate 17, which is installed on a moving platform 9 below it. Each set of weighing hoppers 6 has a conical guide hopper 12 below it. The two conical guide hoppers 12 are fixed to a guide hopper support plate via a mounting plate. The guide hopper support plate is mounted on the moving platform 9 via two sets of guide hopper lifting guide columns 20 and a guide hopper lifting drive cylinder 18. The moving platform 9 is mounted on an intermediate platform via two sets of linear guide rails and a moving platform drive cylinder 8. The weighing hoppers 6 below the vibrating feeders 5 receive real-time feedback from the weighing sensor 7. The control instrument uses the weight signal from the weighing sensor 7 to control the feeding speed and start / stop of the vibrating feeder 5, ensuring accurate quantification of the material and precise control of the material in the weighing hoppers 6 to reach the set weight.

[0023] The steel sheath translation mechanism includes multiple sets of parallel clamping cylinders 24 located below the moving platform 9. The parallel clamping cylinders 24 are fixed on the steel sheath moving seat 22. Below the steel sheath moving seat 22 is the front and rear moving platform 21 of the steel sheath moving seat. The steel sheath moving seat 22 is mounted on the lower platform via linear guide rails and drive cylinders.

[0024] The vibration platform mechanism includes a vibration support plate 13 located below the parallel clamping cylinder 24.

The weighing hopper 6 below the vibrating feeder 5 controls the feeding speed and start / stop of the vibrating feeder 5 through real-time feedback from the weighing sensor 7, ensuring that the material is accurately quantified. When the rubber sleeve placed inside the steel sheath reaches the filling station, the guide hopper descends and extends into the rubber sleeve, and the weighing hopper 6 flips to fill the material into the rubber sleeve. The two weighing systems correspond to the two filling stations, and the primary filling volume and secondary filling volume are set respectively. The rubber sleeve fills the material according to the required weight and density through the sequence of primary filling, vibration, secondary filling, and vibration, realizing the automation of material filling.

The weighing hopper 6 and the guide hopper fixed on it move to the filling position accordingly. The guide hopper lifting drive cylinder 18 drives the conical guide hopper 12 to move downward. The guide hopper 12 is guided into the rubber sleeve by the guide teeth provided at the lower outlet of the conical guide hopper 12. The dustproof sponge adhered to the lower flange of the conical guide hopper 12 completely seals the opening of the rubber sleeve to prevent dust from flying. The opening cylinder pushes the weighing hopper 6 to flip and fill the rubber sleeve with material. At the same time, the pneumatic vibrator 19 installed on one side of the conical guide hopper 12 is activated to prevent material from adhering.

[0030] At least two sets of parallel clamping cylinders 24 are provided below the mobile platform 9; the steel sheath moving seat 22 is installed on the lower platform through the cross-arranged linear guide rails and the front and rear drive cylinders 10 and the left and right drive cylinders 23 of the steel sheath moving seat; the parallel clamping cylinders 24 perform a reciprocating motion of extending, clamping the steel sheath, moving to the right, releasing the steel sheath, retracting, and moving to the left to reset under the drive of the cross-arranged linear guide rails and the front and rear drive cylinders 10 and the left and right drive cylinders 23 of the steel sheath moving seat, so as to place the steel sheaths on the left stepping platform 11 into each work station in sequence.

[0031] After the material is filled, the geared motor 15 starts and forces the vibrating plate 13 and its steel sleeve and rubber sleeve to vibrate up and down simultaneously through the cam 16 and the vibrating plate guide post 14, so that the material in the rubber sleeve is compacted.

[0032] After one steel sheath is removed from the left stepping platform 11 (and placed on the right stepping platform 11), the stepping platform 11 moves one position under the drive of the positioning cylinder and the stepping cylinder, and the left stepping platform 11 sends the next steel sheath to the position to be removed (leaving an empty space on the right stepping platform 11).
