Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a device for improving the turning of special-shaped tablets used in high-efficiency coating machines. Background Art

[0002] High-efficiency coating machine for special-shaped tablets is a kind of equipment widely used in the pharmaceutical industry. It is mainly used for coating drugs. Its unique design can coat drugs of various shapes evenly and efficiently. The high-efficiency coating machine for special-shaped tablets uses a high-speed rotating drum as the main working part, and a number of special-shaped special-shaped tablet structures are fixed on its inner wall. During the working process, these special-shaped tablets will be effectively turned over by the rotation of the drum, and the coating liquid will be evenly sprayed on the surface of the drug with the airflow generated by the fan, and then dried by hot air to form a uniform film on the surface of the drug. In addition, the equipment adopts a fully enclosed design to effectively prevent cross-contamination of drugs during the production process.

[0003] At present, the special-shaped tablets used in existing coating machines are usually directly fixed on the inner wall of the drum in actual application. Although this turning and mixing structure is widely used due to its simplicity and low maintenance cost, however, since the special-shaped tablets in the existing device are fixed to the inner wall of the drum, when the drum drives the special-shaped tablets to rotate in the same direction, this turning and mixing structure is difficult to drive all the substrates to fully turn over, resulting in uneven drug coating thickness. In view of this, we provide a turning and improving device for special-shaped tablets used in high-efficiency coating machines. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a device for improving the turning of special-shaped tablets used in a high-efficiency coating machine.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for improving the flipping of special-shaped tablets for a high-efficiency coating machine, comprising a limit frame, a turning drum is rotatably connected to the inner center of the limit frame, and a limit shaft is rotatably connected to the inner center of the turning drum, the limit shaft is located on one side of the inner part of the limit frame, and the limit shaft is rotatably connected to the inner side of the limit frame through the turning drum, a synchronous gear is rotatably connected to the inner side of the limit frame, and the synchronous gear is rotatably connected to the limit shaft, the synchronous gear is located on one side of the outer wall of the turning drum, and the turning drum is rotatably connected to the inner center of the limit frame through the synchronous gear, the outer wall center of the synchronous gear is connected through one side of the inner wall of the limit frame, and the outer wall of one side of the synchronous gear is rotatably connected to one side of the inner side of the limit frame.

[0006] As mentioned above, a plurality of special-shaped metal plates are rotatably connected to the inside of the mixing drum, and a plurality of conical bars are rotatably connected to the inner edge of the mixing drum at the same time.

[0007] As described above, one side of the outer walls of the shaped metal plate and the conical strip is in contact with the inner wall of the stirring drum, and one side of the outer walls of the shaped metal plate and the conical strip is rotatably connected to the inner wall of the stirring drum.

[0008] As described above, one side of the outer walls of the shaped metal plate and the conical strip is fixedly connected to one side of the outer wall of the limiting shaft, and the shaped metal plate and the conical strip are rotatably connected to the inner edges of the stirring drum and the limiting frame through the limiting shaft.

[0009] As described above, one end of the outer wall of the limiting shaft is connected through the center of the inner wall of the stirring drum, and a driving gear is connected through and fixed to the center of the inner part of the stirring drum on one end of the outer wall of the limiting shaft. The driving gear is located at the center of the inner part of the limiting frame, and one side of the outer wall of the driving gear is rotatably connected to the center of one side of the stirring drum.

[0010] As described above, a meshing rack is provided on one side of the inner wall of the stirring drum, and one side of the outer wall of the synchronous gear is rotatably connected to the inner wall of the stirring drum through the meshing rack.

[0011] As described above, one side of the outer wall of the synchronous gear is rotatably connected to one side of the outer wall of the driving gear through gear meshing, and the synchronous gear is rotatably connected to one side of the inner part of the limiting frame through the driving gear.

[0012] Compared with the prior art, the shaped piece flipping improvement device for an efficient coating machine has the following beneficial effects:

[0013] First, the limiting frame of the present invention is installed inside the coating machine, and the limiting frame is fixedly connected to the center inside the coating machine. Since the limiting frame covers the outside of the stirring drum and limits the stirring drum, the stirring drum can rotate inside the coating machine through the limiting frame. By fixing the shaped metal plate and the conical strip on the outer wall of the limiting shaft respectively, and making the shaped metal plate and the conical strip in contact with the inner wall of the stirring drum, the shaped metal plate and the conical strip can follow the rotation of the limiting shaft and rotate along the inner wall of the stirring drum, and fully stir the base pieces inside the stirring drum, so as to facilitate the subsequent use of the synchronous gear as a transmission medium by the device to drive the stirring drum, the shaped metal plate and the conical strip to rotate simultaneously at the center of the inner part of the limiting frame, and fully stir the base pieces inside the stirring drum.

[0014] II. Inside the coating machine, by fixing the limit frame at the center, the mixing drum can be stably installed and limited. After the driving gear is connected to the driving shaft of the coating machine, the limit shaft rotates accordingly, and further drives the special-shaped metal plate and the conical strip to rotate inside the mixing drum, realizing the effective mixing of the substrates. At the same time, the synchronous gear is rotationally connected inside the limit frame and is connected to the outer walls of the mixing drum and the driving gear through the meshing rack and gear. When the driving gear is started by the driving system of the coating machine, the mixing drum can rotate along the inner wall of the limit frame in the opposite direction of the limit shaft. Thus, through the synchronous gear and its interaction with the meshing rack and the driving gear, the special-shaped metal plate and the conical strip can rotate in different directions simultaneously with the mixing drum, achieving more sufficient and delicate mixing. With the connection and rotation of the driving shaft and the driving gear inside the coating machine, the entire mixing drum is driven to rotate along the inner wall of the limit frame in the opposite direction of the rotation of the limit shaft. This reverse rotation mode optimizes the turning effect of the substrates, ensuring that each piece of medicine can evenly contact the coating liquid during the coating process, enabling the substrates to move not only horizontally but also vertically to obtain mixing power, achieving all-round mixing. Furthermore, this device can improve the coating uniformity through sufficient mixing of the substrates and minimize the unqualified rate of coating caused by insufficient mixing to the greatest extent.

[0015] Other advantages, objectives, and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, the present invention provides a technical solution: a special-shaped sheet turning improvement device for an efficient coating machine, including a limit frame 1. The center of the inside of the limit frame 1 is rotatably connected to a stirring drum 2. The center of the inside of the stirring drum 2 is rotatably connected to a limit shaft 201. The limit shaft 201 is located on one side inside the limit frame 1. The limit shaft 201 is rotatably connected to the limit frame 1 through the stirring drum 2. One side inside the limit frame 1 is rotatably connected to a synchronous gear 3. The synchronous gear 3 is rotatably connected to the limit shaft 201. The synchronous gear 3 is located on one side of the outer wall of the stirring drum 2. The stirring drum 2 is rotatably connected to the center of the inside of the limit frame 1 through the synchronous gear 3.

[0024] The limiting frame 1 is installed inside the coating machine, and the limiting frame 1 is fixedly connected to the center inside the coating machine. Since the limiting frame 1 is wrapped around the outside of the stirring drum 2 and limits the stirring drum 2, the stirring drum 2 can rotate inside the coating machine through the limiting frame 1. By fixing the special-shaped metal plate 202 and the tapered strip 203 on the outer wall of the limiting shaft 201 respectively, and making the special-shaped metal plate 202 and the tapered strip 203 fit the inner wall of the stirring drum 2, the special-shaped metal plate 202 and the tapered strip 203 can follow the rotation of the limiting shaft 201 and rotate along the inner wall of the stirring drum 2 to fully stir the substrates inside the stirring drum 2. After installing the stirring drum 2 inside the coating machine through the limiting frame 1, the driving shaft inside the coating machine is fixedly connected to the center of the outer wall of the driving gear 301 and drives the driving gear 301 to rotate. In view of the fact that one end of the outer wall of the limiting shaft 201 directly penetrates the inner wall of the stirring drum 2 and is fixedly connected to the center of one side of the driving gear 301, when the driving gear 301 rotates, it will drive the limiting shaft 201, the special-shaped metal plate 202 and the tapered strip 203 to rotate inside the stirring drum 2. At the same time, since a synchronous gear 3 is rotatably connected to one side inside the limiting frame 1, and both sides of the outer wall of the synchronous gear 3 are rotatably connected to one side of the inner wall of the stirring drum 2 and one side of the outer wall of the driving gear 301 through the meshing rack 302 and gear meshing respectively. As the driving gear 301 is driven by the coating machine, through the synchronous gear 3 as a transmission medium between the stirring drum 2 and the driving gear 301, the stirring drum 2 can follow the rotation of the driving gear 301 and rotate along the inner wall of the limiting frame 1 in the opposite direction of the rotation of the limiting shaft 201. Thus, through the interaction of the synchronous gear 3 with the meshing rack 302 and the driving gear 301, the special-shaped metal plate 202 and the tapered strip 203 can rotate in different directions simultaneously with the stirring drum 2 to achieve more sufficient and delicate stirring. As the driving shaft inside the coating machine is connected and rotates with the driving gear 301, the entire stirring drum 2 is driven to rotate along the inner wall of the limiting frame 1 in the opposite direction of the rotation of the limiting shaft 201. This rotation mode in the opposite direction optimizes the turning effect of the substrates, ensuring that each piece of medicine can uniformly contact the coating liquid during the coating process, so that the substrates not only move horizontally but also obtain stirring power vertically, realizing all-round stirring. Furthermore, this device can achieve the effect of improving the coating uniformity through sufficient stirring of the substrates, and also minimizes the unqualified coating rate caused by insufficient stirring.

[0025] Such as Figure 1 , Figure 2 and Figure 4As shown, a plurality of special-shaped metal plates 202 are rotatably connected to the inner periphery of the mixing drum 2, and a plurality of tapered strips 203 are rotatably connected to the inner edge of the mixing drum 2 at the same time. One side of the outer walls of the special-shaped metal plates 202 and the tapered strips 203 is in contact with the inner wall of the mixing drum 2, and one side of the outer walls of the special-shaped metal plates 202 and the tapered strips 203 is rotatably connected to the inner wall of the mixing drum 2. One side of the outer walls of the special-shaped metal plates 202 and the tapered strips 203 is fixedly connected to one side of the outer wall of the limiting shaft 201, and the special-shaped metal plates 202 and the tapered strips 203 are rotatably connected to the inner edges of the mixing drum 2 and the limiting frame 1 through the limiting shaft 201.

[0026] The limiting frame 1 is installed inside the coating machine, and the limiting frame 1 is fixedly connected to the center inside the coating machine. Since the limiting frame 1 covers the outside of the mixing drum 2 and limits the mixing drum 2, the mixing drum 2 can rotate inside the coating machine through the limiting frame 1. By fixing the special-shaped metal plates 202 and the tapered strips 203 to the outer wall of the limiting shaft 201 respectively and making the special-shaped metal plates 202 and the tapered strips 203 fit the inner wall of the mixing drum 2, the special-shaped metal plates 202 and the tapered strips 203 can follow the rotation of the limiting shaft 201 and rotate along the inner wall of the mixing drum 2, and fully mix the substrates inside the mixing drum 2, so as to facilitate the subsequent use of the synchronous gear 3 as a transmission medium to drive the mixing drum 2, the special-shaped metal plates 202 and the tapered strips 203 to rotate simultaneously at the center inside the limiting frame 1 and fully mix the substrates inside the mixing drum 2.

[0027] As Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the outer wall of the limiting shaft 201 is connected through the center of the inner wall of the mixing drum 2, and one end of the outer wall of the limiting shaft 201 penetrates and is fixedly connected to the center inside the mixing drum 2 with a driving gear 301. The driving gear 301 is located at the center inside the limiting frame 1, and one side of the outer wall of the driving gear 301 is rotatably connected to the center of one side of the mixing drum 2. A meshing rack 302 is provided on one side of the inner wall of the mixing drum 2, and one side of the outer wall of the synchronous gear 3 is rotatably connected to the inner wall of one side of the mixing drum 2 through the meshing rack 302. One side of the outer wall of the synchronous gear 3 is rotatably connected to one side of the outer wall of the driving gear 301 through gear meshing, and the synchronous gear 3 is rotatably connected to one side inside the limiting frame 1 through the driving gear 301.

[0028] After installing the mixing drum 2 inside the coating machine through the limit frame 1, the driving shaft inside the coating machine is fixedly connected to the center of the outer wall of the driving gear 301, and drives the driving gear 301 to rotate. Given that one end of the outer wall of the limit shaft 201 directly penetrates the inner wall of the mixing drum 2 and is fixedly connected to the center of one side of the driving gear 301, when the driving gear 301 rotates, it will drive the limit shaft 201, the special-shaped metal plate 202, and the tapered strip 203 to rotate inside the mixing drum 2. At the same time, since a synchronous gear 3 is rotatably connected to one side inside the limit frame 1, and both sides of the outer wall of the synchronous gear 3 are rotatably connected to one side of the inner wall of the mixing drum 2 and the outer wall of one side of the driving gear 301 through the meshing rack 302 and gear meshing respectively. As the driving gear 301 is driven by the coating machine, through the synchronous gear 3 as the transmission medium between the mixing drum 2 and the driving gear 301, the mixing drum 2 can follow the rotation of the driving gear 301 and rotate along the inner wall of the limit frame 1 in the opposite direction of the rotation of the limit shaft 201. Thus, through the interaction of the synchronous gear 3 with the meshing rack 302 and the driving gear 301, the special-shaped metal plate 202 and the tapered strip 203 can rotate in different directions simultaneously with the mixing drum 2 to achieve more sufficient and fine mixing. As the driving shaft inside the coating machine is connected and rotates with the driving gear 301, the entire mixing drum 2 is driven to rotate along the inner wall of the limit frame 1 in the opposite direction of the rotation of the limit shaft 201. This rotation mode in the opposite direction optimizes the turning effect of the substrate, ensuring that each tablet of medicine can uniformly contact the coating liquid during the coating process, enabling the substrate to not only move horizontally but also obtain mixing power vertically, thereby achieving all-round mixing. Furthermore, this enables the device to achieve the effect of improving the coating uniformity through sufficient mixing of the substrate, and also minimizes the unqualified rate of coating caused by insufficient mixing.

[0029] Working principle: The limit frame 1 is installed inside the coating machine, and the limit frame 1 is fixedly connected to the center inside the coating machine. Since the limit frame 1 covers the outside of the stirring drum 2 and limits the stirring drum 2, the stirring drum 2 can rotate inside the coating machine through the limit frame 1. By fixing the special-shaped metal plate 202 and the tapered strip 203 on the outer wall of the limit shaft 201 respectively, and making the special-shaped metal plate 202 and the tapered strip 203 fit with the inner wall of the stirring drum 2, the special-shaped metal plate 202 and the tapered strip 203 can follow the rotation of the limit shaft 201 and rotate along the inner wall of the stirring drum 2 to fully stir the substrates inside the stirring drum 2. After installing the stirring drum 2 inside the coating machine through the limit frame 1, the driving shaft inside the coating machine is fixedly connected to the center of the outer wall of the driving gear 301 and drives the driving gear 301 to rotate. In view of the fact that one end of the outer wall of the limit shaft 201 directly penetrates the inner wall of the stirring drum 2 and is fixedly connected to the center of one side of the driving gear 301, when the driving gear 301 rotates, it will drive the limit shaft 201, the special-shaped metal plate 202 and the tapered strip 203 to rotate inside the stirring drum 2. At the same time, since a synchronous gear 3 is rotatably connected to one side inside the limit frame 1, and both sides of the outer wall of the synchronous gear 3 are rotatably connected to one side of the inner wall of the stirring drum 2 and one side of the outer wall of the driving gear 301 through the meshing rack 302 and gear meshing respectively. As the driving gear 301 is driven by the coating machine, through the synchronous gear 3 as a transmission medium between the stirring drum 2 and the driving gear 301, the stirring drum 2 can follow the rotation of the driving gear 301 and rotate along the inner wall of the limit frame 1 in the opposite direction of the rotation of the limit shaft 201. Thus, through the synchronous gear 3 and its interaction with the meshing rack 302 and the driving gear 301, the special-shaped metal plate 202 and the tapered strip 203 can rotate in different directions simultaneously with the stirring drum 2 to achieve more sufficient and fine stirring.
