[0002] A vacuum loader is a type of pneumatic conveying device that uses a vacuum pump to create a vacuum to convey powder and granular materials. It mainly uses vacuum suction to convey granular and powdered materials in a dust-free, sealed pipeline. The vacuum loader uses the pressure difference between the vacuum and the ambient space to form a gas flow in the pipeline, driving the movement of powdered materials, granular and flake objects, thereby completing the conveying process. It is often used for drug packaging. Existing vacuum loaders are unable to weigh the drugs during loading, often resulting in insufficient or excessive drug weight. Consequently, workers are still required to weigh and mix the drugs during the loading process, which not only reduces efficiency but also increases labor intensity.

The tablet medicine is discharged from the unloading pipe to achieve the effect of quantitative unloading. The pressure sensor set on the control panel can sense the pressure to control the unloading amount of the tablet medicine each time. The operation is simple and convenient.

[0016] 2. The present invention is provided with a powder receiving plate and a collection box. During the process of loading the sheet medicine into the vacuum feeding box, the airflow generated by the suction generated by the vacuum air pump can absorb the powdered medicine, so that the powdered medicine is adsorbed on the outer surface of the gauze tube, reducing the amount of powder on the sheet medicine. Each time the weighed sheet medicine in the quantitative feeding box is unloaded, the control panel can be used to control the vacuum air pump to backflush and blow off the powdered medicine adhered to the outer surface of the gauze tube, so that the powdered medicine falls onto the powder receiving plate and falls into the collection box through the powder discharge port for collection, thereby achieving the effect of collecting the powdered medicine.

[0025] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a vacuum feeding type tablet weight automatic adjustment device, including a feed box 1, a feeding tube 2, a vacuum feeding box 3, a gauze cylinder 4, a vacuum air pump 5, a quantitative discharge box 6 and a weighing discharge assembly. A feeding tube 2 is provided on the left side of the bottom surface of the feed box 1, and a vacuum feeding box 3 is provided on the left end of the feeding tube 2. A gauze cylinder 4 is provided on the center of the upper surface of the vacuum feeding box 3, and a vacuum air pump 5 is fixedly installed on the inner side of the gauze cylinder 4. Slide grooves 301 are provided on the left and right sides of the interior of the vacuum feeding box 3, and a guide column 302 is fixedly provided in the slide groove 301. A quantitative discharge box 6 is embedded in the lower inner side of the vacuum feeding box 3, and sliders 601 are fixedly provided on the left and right sides of the quantitative discharge box 6. A discharge pipe 7 is provided on the bottom of the quantitative discharge box 6, and the discharge pipe 7 passes through the center of the bottom surface of the vacuum feeding box 3. A weighing unloading assembly is installed on the two left support legs of the vacuum feeding box 3.

[0026] In this embodiment, the slider 601 matches the slide groove 301, and the slider 601 slides in the slide groove 301, which facilitates the slider 601 to slide up and down along the slide groove 301, thereby achieving the effect of guiding the up and down movement of the quantitative discharge box 6.

[0027] In this embodiment, the guide post 302 passes through the slider 601 , further ensuring the stability of the slider 601 sliding in the slide groove 301 .

[0028] In this embodiment, the outer surface of the quantitative discharge box 6 matches the lower part of the inner surface of the vacuum loading box 3, and when the slider 601 slides to the top of the chute 301, the bottom horizontal height of the quantitative discharge box 6 is higher than the bottom horizontal height of the chute 301. When the slider 601 slides to the bottom of the chute 301, the top horizontal height of the quantitative discharge box 6 is higher than the top horizontal height of the chute 301, which facilitates the quantitative discharge box 6 to block the chute 301 and prevent the tablet medicine from falling into the chute 301.

[0029] In this embodiment, the weighing and unloading assembly includes a mounting plate 8, which is fixedly arranged above the two supporting legs on the left side. An electric telescopic rod 801 is fixedly installed above the mounting plate 8, and a trapezoidal plate 802 is fixedly arranged at the output end of the electric telescopic rod 801.

[0030] In this embodiment, a control panel 9 is installed on the right surface of the vacuum loading box 3 , and the control panel 9 is electrically connected to the pressure sensor 803 .

[0031] In this embodiment, when the slider 601 slides to the bottom of the slide groove 301, the bottom horizontal height of the discharge pipe 7 is equal to the bottom horizontal height of the trapezoidal plate 802. When the electric telescopic rod 801 is extended to the maximum length, the trapezoidal plate 802 is directly below the discharge pipe 7.

[0032] By providing a load-bearing component and a quantitative discharge box 6, when quantitatively discharging the tablet medicine, the control panel 9 is used to set the weight of the quantitative discharge box 6 and the medicine at each time of discharge, and the electric telescopic rod 801 extends to drive the trapezoidal plate 802 to move to the right, and the inclined surface at the right end of the trapezoidal plate 802 pushes the discharge pipe 7 and the quantitative discharge box 6 to move until the pressure sensor 803 on the trapezoidal plate 802 is on the discharge pipe 7. The pressure sensor 803 weighs the discharge pipe 7 and the quantitative discharge box 6, and then the control panel 9 controls the vacuum air pump 5 to start, and the vacuum air pump 5 evacuates the feeding box 3. Under the action of negative pressure, the tablet medicine in the feeding box enters the vacuum upper chamber from the feeding pipe 2. The material box 3 is filled with the medicine and falls into the quantitative discharge box 6. When the pressure sensed by the pressure sensor 803 is equal to the pressure set by the control panel 9, the control panel 9 controls the vacuum air pump 5 and controls the electric telescopic rod 801 to retract at the same time. The electric telescopic rod 801 drives the trapezoidal plate 802 to move to the left until the trapezoidal plate 802 does not block the discharge pipe 7.
