Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceuticals, in particular to a roller structure of a high-efficiency coating machine. Background Art

[0002] Coating is to coat sugar or other film-forming materials on the outer surface of solid drug preparations in specific equipment according to a specific process, so that after drying, it becomes a layer or several layers of multifunctional protective layers of different thickness and elasticity that are tightly adhered to the surface. Film coating of tablets has many advantages. It can ensure the dryness of tablets, achieve the effect of light protection and moisture protection, improve the stability of drugs, cover up bad smells, and improve patient compliance. Two drugs with different mechanisms of action can sometimes be used together to improve the efficacy, but when there are incompatibility taboos between the two, the two can be granulated, coated, and tableted separately to avoid direct contact between the two. Many tablets have small differences in appearance, which can easily cause inconvenience to pharmacists in dispensing and nurses in placing medicines, resulting in the phenomenon of taking the wrong medicine and using the wrong medicine; and the tablets are too similar, which is not conducive to patients' medication. The use of different color coatings can increase the recognition of different tablets and increase the safety of medication. Change the location and speed of drug release. Gastric-soluble, enteric-soluble, sustained-release and controlled-release drugs usually need to be swallowed as a whole tablet to avoid destroying the coating structure and affecting the effects of gastric-soluble, enteric-soluble, and sustained-release controlled-release drugs.

[0003] In the prior art, during the operation of the drum mechanism of the coating machine, the medicine particles in the drum are continuously stirred as the drum rolls, and the coating nozzle is used to spray the coating liquid on the medicine particles in the stirring process. During this process, since the medicine particles are piled up in the drum and rotate and stir, some medicine particles are always located at the bottom of the drum and cannot be fully mixed with the sprayed liquid medicine, resulting in insufficient coating of some medicine particles, which affects the subsequent use of the medicine particles. Utility Model Content

[0004] (I) Technical problems solved: In view of the shortcomings of the prior art, the utility model provides a high-efficiency coating machine drum structure, which can fully mix the drug particles with the drug solution and quickly coat each drug particle, thus solving the problem of uneven contact between some drug particles and the drug solution and low mixing efficiency during the drug coating process.

[0005] (ii) Technical solution: In order to achieve the above-mentioned purpose of fully mixing the medicine particles with the medicine liquid and quickly coating each medicine particle, the utility model provides the following technical solution: a high-efficiency coating machine drum structure, including a box body, a medicine particle drum, an opening and closing assembly is arranged on the front end surface of the box body, a liquid spraying assembly is arranged on the opening and closing assembly, a rotating rod is arranged in the inner cavity of the medicine particle drum through a support rod, the support rod is arranged in the inner cavity of the medicine particle drum parallel to the center line of the medicine particle drum, an S-shaped rotating blade is arranged on the rotating rod, the center of the rotating blade is connected to the rotating rod, and a rotary spring is sleeved on both ends of the rotating rod, one end of the rotary spring is connected to the support rod, and the other end is connected to the end face of the rotating blade.

[0006] Preferably, the opening and closing assembly comprises a circular door, the circular door is connected via a connecting rod, and the connecting rod is connected to the front end surface of the box body.

[0007] Preferably, the liquid spraying assembly comprises a liquid spraying rod, and a liquid spraying head is arranged on the liquid spraying rod.

[0008] Preferably, the connecting rod is hingedly connected to the front end surface of the box body via a hinge.

[0009] Preferably, the medicine pellet drum comprises a central cylindrical surface, and the left and right ends of the central cylindrical surface are connected to a trapezoidal frustum surface.

[0010] (III) Beneficial effects: Compared with the prior art, the utility model provides a high-efficiency coating machine drum structure, which has the following beneficial effects:

[0011] 1. The drum structure of the high-efficiency coating machine can stir the medicine particles to be sprayed in the medicine particle drum through the setting of the rotating blades, so that the medicine particles are fully contacted with the medicine liquid sprayed from the spray head, thereby ensuring the uniformity of the medicine particle coating. During the rotation of the medicine particle drum, when the rotating blades rotate to the bottom of the inner cavity of the medicine particle drum, the medicine particles accumulated at the bottom are blocked by the rotating blades, and the rotating blades are pushed to compress the rotary spring connected to the rotating blades. When the rotating blades hold part of the medicine particles and continue to rise with the medicine particle drum, due to the reduction of the medicine particles, the weight of the medicine particles is lower than the rotation force of the rotary spring, and the rotary spring drives the rotating blades to flip so that the medicine particles on the rotating blades are splashed out. The rotating blades rotate with the medicine particle drum in a cycle. Every time the rotating blades in the medicine particle drum rotate to the bottom of the medicine particle drum, the medicine particles at the bottom of the medicine particle pile can be brought up and turned over to contact with the medicine liquid, thereby ensuring the high efficiency and uniformity of the medicine particle coating.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The drum structure of the high-efficiency coating machine includes a box body 1 and a medicine grain drum 8. The box body 1 includes medicine grain loading and unloading components, which are common components in the prior art and are not described in detail here. An opening and closing component 2 is arranged on the front end surface of the box body 1, and a liquid spraying component 3 is arranged on the opening and closing component 2. A rotating rod 5 is arranged in the inner cavity of the medicine grain drum 8 through a support rod 4. The support rod 4 is arranged in parallel with the center line of the medicine grain drum 8 in the inner cavity of the medicine grain drum 8. An S-shaped rotating blade 6 is arranged on the rotating rod 5. The center of the rotating blade 6 is connected to the rotating rod 5. Rotating springs 7 are sleeved on both ends of the rotating rod 5. One end of the rotating spring 7 is connected to the support rod 4, and the other end is connected to the end face of the rotating blade 6.

[0020] Install the medicine grain drum 8 in the housing 1 to ensure that the medicine grain drum 8 can rotate freely. Install the support rod 4 in the inner cavity of the medicine grain drum 8 parallel to the center line of the medicine grain drum 8. Fix the rotating rod 5 on the support rod 4 to ensure that the rotating rod 5 is stable and does not shake. Install the S-shaped rotating blade 6 on the rotating rod 5 to ensure that the center of the rotating blade 6 is tightly connected to the rotating rod 5. Open the circular door 201 of the opening and closing component 2, and add the medicine grains to be coated into the inside of the medicine grain drum 8. Close the circular door 201 to ensure that the medicine grain drum 8 is sealed. Start the equipment to make the medicine grain drum 8 start to rotate. Spray the medicine liquid into the inside of the medicine grain drum 8 through the spray head 302 of the spray component 3. During the rotation of the medicine pellet drum 8, the S-shaped rotating blade 6 turns up the medicine pellets at the bottom, so that the medicine pellets are fully in contact with the liquid medicine. When the rotating blade 6 rotates to the bottom and encounters the accumulation of medicine pellets, the medicine pellets push the rotating blade 6 to compress the rotary spring 7. When the rotating blade 6 rises with the drum and encounters a decrease in medicine pellets, the rotary spring 7 recovers and splashes the medicine pellets out to achieve uniform distribution of the medicine pellets. When the medicine pellets are coated, stop the equipment, open the circular door 201, and take out the coated medicine pellets. Clean the equipment and prepare for the next use.

[0021] Through the interaction between the S-shaped rotating blades 6 and the rotary springs 7, the medicine particles can be continuously turned up and evenly distributed, so as to fully contact with the medicine liquid, greatly improving the coating efficiency. The design of the rotating blades 6 allows each medicine particle to be evenly coated, avoiding the problem of uneven coating and improving the quality of the medicine. The setting of the opening and closing component 2 and the liquid spraying component 3 makes the operation of the equipment easier, and the operator can easily add medicine particles and spray the medicine liquid. The setting of the support rod 4 and the rotating rod 5 makes the medicine particle drum 8 structure stable, and it is not easy to shake during the rotation, ensuring the stable operation of the equipment.

[0022] The opening and closing assembly 2 includes a circular door 201 , and the circular door 201 is connected via a connecting rod 202 , and the connecting rod 202 is connected to the front end surface of the box body 1 .

[0023] The circular door 201 is designed to fit tightly on the front face of the housing 1 to form an effective seal. This ensures that during the coating process, the drug solution will not leak out of the drug pellet drum 8, thereby maintaining the stability of the coating environment. At the same time, good sealing performance also helps to reduce the waste of drug solution and environmental pollution, and improves the economy and environmental protection of drug production. The connecting rod 202 of the opening and closing component 2 is connected to the front face of the housing 1 by a stable connection method (such as hinged connection), ensuring the stability and safety of the circular door 201 during the opening and closing process. This design avoids the risk of equipment damage or personal injury due to improper operation, and improves the overall safety and reliability of the equipment.

[0024] The design of the opening and closing assembly 2 makes the cleaning and maintenance of the equipment more convenient. When it is necessary to clean the medicine pellet drum 8 or replace parts, the operator can easily open the circular door 201 for operation. This design reduces the difficulty and time cost of maintenance work and improves the maintenance efficiency of the equipment.

[0025] The liquid spraying assembly 3 comprises a liquid spraying rod 301, and a liquid spraying head 302 is arranged on the liquid spraying rod 301. The connecting rod 202 is connected to the front end surface of the box body 1 by a hinge 203 in an articulated manner.

[0026] The design of the liquid spraying rod 301 and the liquid spraying head 302 enables the liquid medicine to be sprayed evenly and accurately onto the medicine grains in the medicine grain drum 8. The liquid spraying head 302 is mounted on the liquid spraying rod 301 and can be adjusted as needed to ensure that the coverage and spraying amount of the liquid medicine reach the best state. This design not only improves the uniformity and efficiency of the coating, but also reduces the waste of the liquid medicine and reduces the production cost. The connecting rod 202 in the opening and closing assembly 2 is connected to the front end face of the casing 1 by a hinge 203 in an articulated manner, and this connection mode brings convenience and stability in operation. The articulated design enables the circular door 201 to be opened and closed flexibly without the need for complicated operations or tools. At the same time, the articulated connection mode also ensures that the circular door 201 can fit tightly on the front end face of the casing 1 when closed, forming an effective seal to prevent the liquid medicine from leaking out.

[0027] The medicine pellet drum 8 comprises a central cylindrical surface, and the left and right ends of the central cylindrical surface are connected to a trapezoidal frustum surface.

[0028] The central cylindrical surface design of the medicine pellet drum 8 enables the medicine pellets to rotate and roll smoothly inside the drum. When the medicine pellet drum 8 rotates, the medicine pellets are evenly distributed on the central cylindrical surface, thereby ensuring that each medicine pellet can fully contact the liquid medicine sprayed by the liquid spraying assembly 3. This design greatly improves the uniformity of the coating, so that each medicine pellet can obtain a uniform and complete coating layer. The design of the trapezoidal frustum surface enables the medicine pellet drum 8 to have smaller openings at both ends, which can more effectively concentrate the medicine pellets in the center of the medicine pellet drum 8 for flipping and stirring. At the same time, the inclination angle of the trapezoidal frustum surface helps the medicine pellets to form effective rolling and flow inside the drum. When the medicine pellet drum 8 rotates, the medicine pellets can more easily roll to the central area of ​​the drum under the guidance of the trapezoidal frustum surface, so as to make more sufficient contact with the rotating blades 6 and the liquid medicine. This design improves the rolling efficiency of the medicine pellets and further enhances the coating effect.

[0029] Working principle: after adding the medicine particles to be coated into the medicine particle drum 8, the medicine particle drum 8 is driven to rotate. During the rotation of the medicine particle drum 8, the rotating blades 6 can flip the medicine particles at the bottom of the inner cavity of the medicine particle drum 8 back to the upper surface of the medicine particle pile. The specific process is that when the rotating blades 6 rotate to the bottom of the inner cavity of the medicine particle drum 8, the medicine particles accumulated at the bottom are blocked by the rotating blades 6, and the rotating blades 6 are pushed to compress the rotary springs 7 connected to the rotating blades 6. When the rotating blades 6 hold some of the medicine particles and continue to rise with the medicine particle drum 8, due to the reduction of the medicine particles, the weight of the medicine particles is lower than the rotation force of the rotary springs 7. The rotary springs 7 drive the rotating blades 6 to flip over so that the medicine particles on the rotating blades 6 are splashed out, and the rotating blades 6 rotate with the medicine particle drum 8 in a cycle. Each time the rotating blades 6 in the medicine particle drum 8 rotate to the bottom of the medicine particle drum 8, the medicine particles at the bottom of the medicine particle pile can be brought up and turned over for contact with the medicine liquid, thereby ensuring the high efficiency and uniformity of the medicine particle coating.
