When the coating operation is carried out, the tablets are required to be tableted and then sub-packaged by film coating liquid, wherein the film coating liquid is a plastic film layer attached to the surface of the tablets, and before the coating operation is carried out, a coating film is required to be prepared.
In the prior art, when the coating film is prepared, as the coating powder and the passivation water are required to be mixed for preparation of the traditional coating film, when the coating powder is driven by a stirring shaft to be mixed and melted in the passivation water by the traditional mixing preparation equipment, the coating powder is inevitably contacted with the stirring shaft in the middle of the mixing container and adhered to the surface of the stirring shaft when the coating powder is added into the mixing container, so that the utilization rate of the coating powder is low, and the concentration of the prepared coating liquid is reduced.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention solves the problems that coating powder is easy to adhere to a stirring shaft when the existing coating liquid is prepared, so that the utilization rate of the coating powder is low, and the concentration of the prepared coating liquid is reduced.
The technical scheme adopted for solving the technical problems is as follows:
the film coating liquid for the Fuyankang tablet consists of the following raw materials in percentage by weight:
film forming material: 50% -60%;
and (3) a plasticizer: 28% -30%;
coloring agent: 10% -12%;
defoaming agent: 1% -2%;
wherein, the film forming material adopts modified methyl cellulose-HPMC; the plasticizer is composed of polyethylene glycol, talcum powder and titanium dioxide.
The preparation equipment of the film coating liquid of the Fuyankang tablet comprises a sealing cover and a mixing container; the sealing cover is connected to the top of the mixing container in a fit way; the bottom of the mixing container is provided with a base, and the top surface of the middle part of the base is fixedly connected with a screw rod; the screw rod is in threaded connection with the bottom of the mixing container; an embedded shell is fixedly connected inside the mixing container, and a rotating ring is rotationally connected inside the embedded shell; the outer side of the embedded shell is rotationally connected with a stirring blade, and the stirring blade is movably connected in the mixing container; the inside wall of swivel ring is provided with the internal thread, just the hob with swivel ring threaded connection is pouring coating powder into mixing vessel afterwards, utilizes the vortex state of purified water, avoids coating powder and mixing vessel inner wall contact, and then leads to the utilization ratio decline of coating powder.
Preferably, the top surface around the base is fixedly connected with a plurality of groups of straight rods which are circumferentially and symmetrically arranged; the tops of the straight rods are movably connected with a connecting plate, and the other ends of the connecting plates are fixedly connected with guard rings; the bottom of the mixing container is attached to the top of the guard ring; the straight rod is sleeved with a spring, two ends of the spring are fixedly connected with a connecting plate and a base respectively, when the mixing container moves downwards, the mixing container is driven to move upwards, and then the spiral rod and the rotating ring are driven to move reversely, so that the rotating ring rotates reversely, and then the stirring blades are driven to rotate reversely, so that vortex is reversed, and after coating powder and purified water are mixed, the coating powder and purified water can be fully mixed.
Preferably, the outer side of the embedded shell is fixedly connected with a first fixing seat; the stirring blade is connected in the first fixed seat in a sliding way; the inner side of the embedded shell is fixedly connected with a second fixing seat, and the rotating ring is connected in the second fixing seat in a sliding manner; one end of the stirring blade, which is close to the first fixing seat, is clamped with a first magnetic block, and one end of the rotating ring, which is close to the second fixing seat, is clamped with a second magnetic block; the first magnetic block is magnetically connected with the second magnetic block, so that when the follow-up coating powder is poured into the mixing container, the coating powder can be driven by purified water in a vortex state, the problem of adhesion caused by contact with the inner side wall of the mixing container is avoided, and the utilization efficiency of the coating powder is improved.
Preferably, the top of the sealing cover is provided with symmetrically arranged blanking grooves; the vertical line of the blanking groove is positioned between the side wall of the mixing container and the embedded shell; a slope block is arranged at the bottom of the mixing container; the outside of the top of the mixing container is fixedly connected with symmetrically arranged handles, wherein the discharging groove is in slope arrangement, so that when the coating powder is poured into the mixing container, the coating powder can enter purified water in a vortex state along the discharging groove.
The invention has the technical effects and advantages that:
according to the film coating liquid for Fuyankang tablets and the preparation equipment thereof, provided by the invention, the mixing container and the screw rod arranged at the bottom of the mixing container are arranged, the mixing container is manually pressed downwards, the rotating ring in the mixing container is driven to rotate in the embedded shell, the first magnetic block and the second magnetic block are connected by magnetic force, the screw rod can drive the rotating ring to rotate, the stirring blades are driven to rotate in the mixing container, the stirring blades are driven to rotate, purified water in the mixing container flows, vortex is generated, coating powder is led in, the coating powder is prevented from adhering to the inner wall of the mixing container, and the mixing effect of the coating powder and the purified water is realized.
