[0002] Since the mid-20th century, in order to improve the therapeutic effect of drugs and patient medication compliance, sustained-release and controlled-release technologies have been applied to the manufacture of tablets. Through special pharmaceutical formulation technologies, such as multi-layer coating and microencapsulation, drugs can be released slowly and continuously in the body. For example, some drugs for treating cardiovascular diseases, when made into sustained-release tablets, can reduce the frequency of medication for patients, maintain the effective concentration of the drug in the body, reduce the peak-valley effect of the drug, and improve the safety and efficacy of the drug.

[0003] In existing technologies, for most oral tablets in pharmaceutical companies, such as cold medicine tablets and antibiotic tablets, coating and granulation equipment is essential. After the core drug particles are made, these tablets need to be coated by the coating and granulation equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1:

[0025] The existing coating cylinders are typically inconvenient to disassemble, clean, and maintain. Furthermore, after coating, they usually require manual cleaning, increasing workload and time, and reducing the effectiveness of cleaning. Therefore, this invention provides a preferred embodiment of a coating and granulation device for tablet processing, for example... Figure 1-4 As shown: A coating and granulation device for tablet processing includes a body 1, with support legs 2 fixedly installed at equal intervals on both sides of the bottom of the body 1, an installation and disassembly assembly 3 provided on the surface of the body 1, a coating cylinder 4 provided on the surface of the installation and disassembly assembly 3, and an automatic cleaning assembly 5 provided on the top of the body 1.

[0026] The installation and disassembly assembly 3 specifically includes: a motor 311, which is fixedly installed between the inner walls of the body 1; a mounting groove box 312, which is fixedly installed at the output end of the motor 311; a magnet 313, which is fixedly installed on the inner wall surface of the mounting groove box 312; a connecting disc 314, which is fixedly installed on the back of the coating tube 4; a magnet 315, which is fixedly installed on the other side of the connecting disc 314; a groove block 316, which is circumferentially and equidistantly fixed on the outer wall of the connecting disc 314; and sliding grooves 317, which are respectively opened on both sides of the inner wall of the mounting groove box 312.

[0027] The outer wall of the connecting plate 314 engages with the inner wall of the mounting groove box 312, the surface of the second magnet 315 attracts the surface of the first magnet 313, and the outer wall of the groove block 316 engages with the inner wall of the mounting groove box 312.

[0028] The mounting recess box 312 has threaded holes on both sides. A knob screw 318 is threadedly connected to the inner wall of the threaded hole.

A positioning block 3111 is fixedly installed at equal intervals on the other side of the cross slide plate 319. The other side of the positioning block 3111 extends to the inner wall of the recessed locking block 316 and engages with it.

[0029] In this example, the coating tube 4 can be disassembled by setting the installation and disassembly assembly 3. The operator rotates the knob screw 318, and under the action of the threaded hole, the knob screw 318 drives the cross slide plate 319 and the positioning block 3111 to disengage from the locking of the groove block 316. Then, the connecting plate 314 and the groove block 316 are taken out from the installation groove box 312 through the coating tube 4, and the second magnet 315 is separated from the first magnet 313, thereby achieving the function of installation and disassembly.

[0030] Example 2:

[0031] Based on Embodiment 1, a preferred embodiment of the coating and granulation apparatus for tablet processing provided by this utility model is, for example... Figure 1-4 As shown: The automatic cleaning component 5 specifically includes: an external threaded connecting pipe 511, which is uniformly and circumferentially connected to the outer wall of the coating tube 4; an internal threaded cover 512, which is threadedly connected to the outer wall of the external threaded connecting pipe 511; a sealing rod 513, which is fixedly installed on the inner wall surface of the internal threaded cover 512; a sliding plate 514, which is fixedly installed on the top of the machine body 1; and a second motor 515, which is fixedly installed on one side of the machine body 1.

[0032] The other end of the sealing rod 513 moves through the inner wall of the external threaded connecting pipe 511 and extends into the inside of the coating tube 4. The output end of the motor 515 is fixedly installed with a lead screw 516. The outer wall of the lead screw 516 is threadedly connected to a sliding hanging plate 517. The outer wall of the sliding hanging plate 517 is slidably connected to the inner wall of the sliding groove plate 514. An electric telescopic rod 518 is fixedly installed on one side of the bottom of the sliding hanging plate 517.

[0033] The telescopic end of the electric telescopic rod 518 is fixedly installed with a connecting rod 519. The other end of the connecting rod 519 extends into the interior of the coating tube 4. The other end of the connecting rod 519 is fixedly installed with a water distribution tank 5111. Spray nozzles 5112 are evenly and equidistantly connected to the outer circumference of the water distribution tank 5111.

[0034] A support box 5113 is fixedly installed on the top of the sliding hanging plate 517. A high-pressure pump 5114 is fixedly installed on the top of the sliding hanging plate 517. Connecting pipes 5115 are installed on both sides of the high-pressure pump 5114. The other end of the connecting pipe 5115 is connected to the bottom of the support box 5113. The other end of the other connecting pipe 5115 is connected through the top of the sliding hanging plate 517 and extends into the interior of the coating cylinder 4 and is connected to the surface of the water distribution tank 5111. A delivery pipe 5116 is installed at equal intervals on the top of the support box 5113. A solenoid valve 5117 is provided on the outer wall of the delivery pipe 5116. A liquid storage tank 5118 is installed at the other end of the delivery pipe 5116.

[0035] In this example, the automatic cleaning component 5 enables automatic cleaning of the inside of the coating cylinder 4. One storage tank 5118 holds cleaning fluid, and the other holds clean water. When the solenoid valve 5117 is energized, the cleaning fluid enters the support box 5113 through the delivery pipe 5116. The high-pressure pump 5114 is started, and the cleaning fluid enters the water distribution tank 5111 through the connecting pipe 5115. Then, it is sprayed through the nozzle 5112. After that, the solenoid valve 5117 and the high-pressure pump 5114 are closed, and another solenoid valve 5117 is started, allowing clean water to fall into the support box 5113. The high-pressure pump 5114 is started again, and finally, the inside is rinsed through the nozzle 5112, thus achieving the effect of automatic cleaning.

[0036] Working principle: First, the starting motor 311 drives the mounting groove box 312 to rotate, which in turn drives the connecting disc 314, the groove locking block 316, and the coating tube 4 to rotate, allowing for the rotational processing of tablets. When the coating tube 4 needs to be disassembled for cleaning and maintenance, the operator rotates the knob screw 318. Under the action of the threaded hole, the knob screw 318 drives the cross slide plate 319 and the positioning block 3111 to disengage from the locking of the groove locking block 316. Then, the connecting disc 314 and the groove locking block 316 are released from the mounting groove box 312 via the coating tube 4. Remove the magnet from the recessed box 312, separating magnet two 315 from magnet one 313. When cleaning the inside of the coating cylinder 4 is required, one storage tank 5118 holds cleaning solution, and the other holds clean water. Power on the solenoid valve 5117, and the cleaning solution enters the support box 5113 through the delivery pipe 5116. Start the high-pressure pump 5114, and the cleaning solution enters the water distribution tank 5111 through the connecting pipe 5115, then is sprayed through the nozzle 5112. Afterward, close the solenoid valve 5117 and the high-pressure pump 5114. 14. Activate another solenoid valve 5117 to allow clean water to fall through the delivery pipe 5116 into the support box 5113. Start the high-pressure pump 5114, and clean water enters the water distribution tank 5111 through the connecting pipe 5115. Finally, the interior is rinsed through the nozzle 5112. When it is necessary to discharge wastewater from the coating cylinder 4, the operator rotates the inner threaded cover 512, separating the inner threaded cover 512 from the outer threaded connecting pipe 511. The sealing rod 513 disengages from the seal inside the outer threaded connecting pipe 511. At this time... Wastewater can be discharged from the external threaded pipe 511 under the action of gravity. When it is necessary to recycle the water distribution tank 5111, the electric telescopic rod 518 is started to work. The connecting rod 519 drives the water distribution tank 5111 to recycle. The motor 515 is started to drive the lead screw 516 to rotate. The rotation of the lead screw 516 drives the sliding hanging plate 517 to slide on the sliding groove plate 514. Finally, the electric telescopic rod 518 is driven to move the sliding hanging plate 517 to one side of the machine body 1, thereby achieving the functions of installation, disassembly and automatic cleaning.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
