Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a mixing granulator for tablet production. Background Art

[0002] After searching the patent document with the announcement number CN214863336U, the movable head connected to the adhesive nozzle is rotated and controlled by changing the sliding position between the ball head rod and the fixed cylinder. When the nozzle is not in use, it is placed inside the ball sleeve. By shrinking the nozzle into the ball sleeve, dust will not block the nozzle of the nozzle.

[0003] The patent document discloses that when mixing and granulating the drug powder, the existing stirring and mixing device will leave some unmixed drug powder at the bottom edge of the mixing tank. When the adhesive is subsequently sprayed, the drug powder at this position will be stuck together again, resulting in uneven mixing of the drug powder in the drug granules. At the same time, the drug powder that is not stuck together will clump together to form larger particles under the action of the adhesive, and may be lifted up and attached to the nozzle during the stirring and mixing process, causing uneven spraying of the adhesive, and also causing trouble when the nozzle is retracted.

[0032] In this embodiment, the closing mechanism 3 includes a flip seat 36, which is fixed on the top of the base 6, and a flip cover plate 31 is hinged on the upper end of the flip seat 36. A flip hydraulic rod 32 is arranged on the lower side of the flip seat 36 to drive the flip cover plate 31 to flip. A vacuum pump 33 is fixed on the top of the flip cover plate 31. The air inlet end of the vacuum pump 33 is connected to a filter tube 34 through an air pipe. The lower end of the filter tube 34 passes through the flip cover plate 31 and extends into the top side of the granulating tank 1. The air outlet end of the vacuum pump 33 is connected to the filter tube 34 through an air pipe. The air pipe is connected to a blowing air frame 35, and a nozzle extending into the interior of the granulating tank 1 is arranged on the inner side of the blowing air frame 35. The telescopic part of the flip hydraulic rod 32 is shortened to drive the flip cover 31 to flip to close the top of the granulating tank 1, and then the vacuum pump 33 extracts and filters the interior of the granulating tank 1 through the filter tube 34, so that the gas is sent into the blowing air frame 35 through the air pipe by the vacuum pump 33, and the powder on the bottom side of the granulating tank 1 is purged by the blowing air frame 35 to accelerate its mixing.

[0033] In this embodiment, the mixing mechanism 5 includes a mixing frame 54, which is rotatably connected to the inside of the granulating tank 1, and two mixing paddles 56 are rotatably connected to the outside of the mixing frame 54. The end of the mixing paddle 56 extending into the mixing frame 54 is provided with teeth, and the lower side of the teeth of the mixing paddle 56 is meshed with a gear ring 55. The end of the mixing frame 54 extending into the bottom of the granulating tank 1 is provided with a driven bevel gear 53, and the mixing frame 54 is fixedly connected to the driven bevel gear 53, and the driven bevel gear 53 is meshed with a driving bevel gear 52 on one side. The driving bevel gear 52 is installed on the rotating part of the mixing motor 51. The motor 51 is fixed to one side of the base 6, the gear ring 55 is fixedly connected to the bottom side of the granulating tank 1, and mixing plates for turning up the powder are provided on the front and rear sides of the mixing frame 54. The rotating part of the mixing motor 51 drives the active bevel gear 52 to rotate, and the mixing frame 54 is driven to rotate inside the granulating tank 1 by the rotation of the active bevel gear 52 and the driven bevel gear 53. The mixing plate is used to turn up the powder by the rotation of the mixing frame 54, and the teeth of the mixing paddle 56 are meshed with the gear ring 55, so that the mixing paddle 56 can spin when the mixing frame 54 rotates.

[0034] In this embodiment: the discharge mechanism 4 includes a cylinder 41, which is fixed at the lower side of the turning seat 36, and a closing plate 42 is fixed to the telescopic part of the cylinder 41. The granulating tank 1 is provided with a discharge port at the position of the closing plate 42, and the base 6 is provided with a recess at the lower side of the granulating tank 1, and a discharge trough 7 for delivering the granules is provided at the lower side of the base 6. The discharge trough 7 corresponds to the discharge port of the granulating tank 1. The closing plate 42 is pulled and moved by the telescopic part of the cylinder 41 to open the discharge port of the granulating tank 1, and then the granules are guided into the discharge trough 7 of the base 6, and then the granules are delivered by the discharge trough 7.

[0035] Working principle: When in use, first, the telescopic part of the hydraulic rod 32 is extended and pushes the flip cover 31 to flip upward, and then the upper end of the granulation tank 1 is opened, and then the various medicinal powders to be mixed are poured into the granulation tank 1, and then the telescopic part of the hydraulic rod 32 is shortened and drives the flip cover 31 to flip downward to close the top of the granulation tank 1;

[0036] At this time, the rotating part of the mixing motor 51 drives the mixing frame 54 to rotate in the granulating tank 1 through the transmission of the active bevel gear 52 and the driven bevel gear 53, and the rotation of the mixing frame 54 drives its mixing plate to turn up the powder in the granulating tank 1. At the same time, through the meshing of the teeth of the mixing paddle 56 and the gear ring 55, the mixing paddle 56 is rotated when the mixing frame 54 rotates, thereby accelerating the mixing of the turned-up powder.

[0037] In addition, when the powder is mixed, the air at the filter tube 34 is sucked through the air inlet end of the suction pump 33, and then the filter tube 34 sucks the air on the upper side of the granulating tank 1 and filters the powder. The sucked air enters the blowing air frame 35 through the air pipe, and the air is blown back to the bottom side of the granulating tank 1 through the blowing air frame 35, and then the powder at the edge of the granulating tank 1 is turned up, so as to accelerate the mixing of the whole powder.

[0038] When the medicine powder is evenly mixed, the adhesive is sprayed into the granulation tank 1 through the spray pipe 2, and then the medicine powder and the adhesive are mixed by stirring to form medicine granules. After the medicine powder in the granulation tank 1 is completely formed into medicine granules, the closing plate 42 is driven by the telescopic part of the cylinder 41 to separate from the cooperation with the discharge port of the granulation tank 1, and then the medicine granules are sent out from the discharge port of the granulation tank 1 and enter the discharge trough 7, and the medicine granules are then sent out from the discharge trough 7. In addition, the vacuum pump 33 stops starting during the process of sending out the medicine granules.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
