Traditional Chinese medicine tablet transferring mechanism and method

Technical Field

The invention belongs to the technical field of traditional Chinese medicine pharmacy production, and particularly relates to a traditional Chinese medicine tablet transfer mechanism and a method thereof.

Background

The pharmaceutical industry, including traditional chemical pharmaceuticals, biopharmaceuticals, traditional Chinese medicine pharmaceuticals and pharmaceutical preparations, some pharmaceutical intermediate manufacturing enterprises and some health product manufacturing enterprises are also related to pharmaceutical engineering specialties. Because the global importance of human health is increasing, the attention of "medicine" as one of the most important commodities for ensuring human health is increasing, and higher requirements on the variety, quality, effect and the like of the medicine are provided.

When traditional Chinese medicine is prepared into tablets, powdered medicines are required to be processed into tablets through pharmaceutical equipment, usually tablet forming is carried out through a tablet pressing device, and the existing tablet pressing device can be used for pressing circular tablets, lettering tablets, special-shaped tablets, double-layer tablets, multi-layer tablets, annular tablets, core-spun tablets and other tablet types, and the tablet types are various. For example, the chinese utility model patent publication No. CN210047129U, entitled (20200211) discloses a high-efficiency tablet pressing device for powdery drugs, which comprises a storage hopper, a tablet pressing box, a dosing assembly and a tablet pressing table, the utility model discloses a rotating plate drives the bottom end of a material guiding pipe to rotate, when moving to the upper part of a forming plate, the moving plate drives a baffle to move through a first magnet and a first electromagnet, and a dosing hole on the baffle is communicated with a first dosing hole and a second dosing hole, so that the powder falls into the forming hole of the forming plate through a dosing hole; repeatedly moving the pressing plate and the forming block up and down through the cam to extrude and form the medicinal powder; when the second magnet position on third magnet and the shaping plate is relative repulsion, make the shaping plate outwards remove, shaping hole and the hole alignment of giving medicine to the next round of writing, the tablet is discharged and is collected from the hole of giving medicine to the next round of writing, then the rotor plate rotates, and second magnet and third magnet position stagger, and the shaping plate returns rapidly under the effect of second spring and spring plate, and shaping hole bottom seals.

The traditional Chinese medicine tablet at present has the following problems in the production process: the existing equipment needs to transfer the traditional Chinese medicine tablets in the production process and then perform punch forming, two steps are needed to be performed separately, and the traditional Chinese medicine tablets and the two steps cannot be well connected, so that the processing efficiency of the whole production line is low; secondly, a plurality of air cylinders and a plurality of motors are required to be applied in the production process of the traditional Chinese medicine tablets, the uniformity of movement cannot be ensured through the air cylinders, and the uniformity of rotation cannot be ensured through the motors, so that the deviation of a moving position is easy to occur during use, the moving precision is reduced, and the equipment cost is increased due to multiple uses; (III) in traditional chinese medicine tablet stamping forming process, most all punch the likeness slice of stamping with the mould through upper end pressure head down-stamping with likepowder traditional chinese medicine tablet, only punch through one end, can't guarantee the completeness and the pleasing to the eye degree of traditional chinese medicine tablet shape easily to still need snatch traditional chinese medicine tablet through the manipulator after the punching press, complex operation increases the cost.

Especially, the air cylinder is mostly used for transferring in the transferring process of the traditional Chinese medicine tablets, and the air cylinder is easy to have moving errors after working for a long time, so that the traditional Chinese medicine tablets cannot be accurately moved to a stamping position for stamping, the shapes of the traditional Chinese medicine tablets after stamping are incomplete and uniform, and the quality of the traditional Chinese medicine tablets is greatly reduced.
