[0020] Specifically, the top of the receiving seat 10 is provided with a U-shaped groove for receiving granular or powdered catalysts. One end of the bottom of the receiving seat 10 is fixedly connected to one end of the elastic sealing strip 12, and the other end of the elastic sealing strip 12 is fixedly connected to the bottom wall of the metering chamber 8. The sealing strip 12 ensures the sealing of the bottom of the receiving seat 10 and prevents granular or powdered catalysts from falling between the receiving seat 10 and the bottom wall of the metering chamber 8.

[0021] Specifically, the scraper component 13 includes a support base 131, a slide groove 132, a U-shaped plate 133, a sliding opening 134, a support groove 135, a spring 136, an anti-detachment disc 137, a cylindrical block 138, and an elastic rubber strip 139. One end of the support base 131 is fixedly connected to the piston rod end of the cylinder 2. The bottom of the support base 131 is provided with a slide groove 132, and the U-shaped plate 133 is slidably sleeved in the slide groove 132. The top two ends of the U-shaped plate 133 are respectively recessed with support grooves 135. One end of the support groove 135 is recessed in the support groove.

[0022] Specifically, the guide groove 14 has a hexagonal structure, and the two corners of the guide groove 14 are respectively provided with recessed grooves 141. One end of the grooves 141 is connected to the guide ramps 142, and the guide ramps 142 are symmetrically arranged in parallel.

[0023] The working principle and process are as follows: Feed pipe 3 connects to the granular or powdered catalyst storage bin. A tubular auger conveyor is installed on the pipeline to transport the granular or powdered catalyst to the metering chamber 8. The catalyst falls into the U-shaped groove of the receiving seat 10. The weighing sensor 11 is a WSSCLC type, electrically connected to a control panel with a display screen. The control panel is fixedly installed on the outer wall of the housing 1 and displays the weighing value. When the required addition amount is reached, the solenoid valve 3 stops, cutting off the conveying of the granular or powdered catalyst. Then, cylinder 2 operates, driving the scraper 13 to move towards the receiving seat 10. One end of the metering chamber 8 has an embedded... The groove is used to receive the scraper 13. The cylindrical blocks 138 on both sides of the scraper 13 move in the guide groove 14. The cylindrical blocks 138 first move diagonally downward along the guide ramp 142 on the right side of the guide groove 14, which in turn drives the U-shaped plate 133 to move downward. The U-shaped plate 133 moves diagonally downward from the embedded groove, and then the elastic rubber strip 139 contacts the inner wall of the U-shaped groove of the receiving seat 10. Then the scraper 13 moves linearly along the bottom horizontal groove of the guide groove 14. The elastic rubber strip 139 cooperates with the U-shaped plate 133 to scrape the catalyst in the U-shaped groove of the receiving seat 10. The catalyst finally falls into the discharge port at the bottom of the metering chamber 8. The discharge port is connected to the discharge hopper 7. The catalyst is discharged from the discharge hopper 7 to the pharmaceutical processing equipment. During preparation, the cylindrical block 138 moves to the leftmost end of the guide groove 14 and, under the elastic force of the spring 136, extends into the groove 141, preventing the cylindrical block 138 from moving along the bottom horizontal groove of the guide groove 14 during retraction. Then, the cylinder 2 retracts, driving the scraper 13 to retract. The cylindrical block 138 of the scraper 13 moves along the upper horizontal groove of the guide groove 14, causing the U-shaped plate 133 to rise. The elastic rubber strip 139 detaches from the inner wall of the U-shaped groove of the receiving seat 10 and finally moves into the embedded groove of the metering chamber 8. At the same time, under the elastic force of the spring 136, the cylindrical block 138 extends into the groove 141 at the rightmost end of the guide groove 14, preventing the cylindrical block 138 from moving out of the guide groove 14 during retraction. The horizontal groove above the trough 14 moves; when liquid catalyst needs to be added, the feed pipe 2 4 connects to the liquid catalyst storage tank, the solenoid valve 1 41 opens, the electric telescopic rod 6 works, the electric telescopic rod 6 drives the piston 15 to move in the cylindrical cavity 9, thereby drawing liquid catalyst into the cylindrical cavity 9. The required volume is determined by the scale line on the observation window 101. When the required amount is reached, the electric telescopic rod 6 stops, the solenoid valve 1 41 closes, the solenoid valve 2 51 opens, the discharge pipe 5 connects to the pharmaceutical processing equipment, the electric telescopic rod 6 works, pushing the piston 15 to move, the piston 15 squeezes out the liquid catalyst in the cylindrical cavity 9, and finally the liquid catalyst is discharged into the pharmaceutical processing equipment through the discharge pipe 5.

[0024] It should be noted that the specific models and specifications of cylinders, solenoid valves, electric telescopic rods, weighing sensors, and control panels need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be described in detail here.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
