Description

Technical Field

[0001] This utility model belongs to the technical field of capsule pharmaceutical production and processing equipment, and in particular relates to a polishing and dust removal device for capsule processing. Background Technology

[0002] In the production of Yandan Yixin Capsules, in order to ensure that the drug can reach the corresponding organs in the human body, it is necessary to ensure that the capsule shell has sufficient anti-dissolution properties. In addition to the composition of the capsule shell raw materials, the smoothness of the capsule shell also affects the dissolution properties of the capsule shell. The smoother the capsule shell surface, the higher the anti-dissolution stability of the capsule shell.

[0003] Currently, most capsule polishing machines have a straight cylindrical structure, with material fed on one side for polishing and finished product output on the other side. To ensure polishing quality, the cylinder needs to be long enough. However, this increases the polishing time. Polishing is a friction process, and a longer processing time will generate more heat, which can easily cause heat deformation of the capsule shell and affect product quality. Therefore, a polishing machine that can improve the above problems is needed to meet the processing needs of capsule pharmaceutical production. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] A polishing and dust removal device for capsule processing includes a polishing chamber, a polishing assembly, a drive box 5, a central collection box 4, a dust removal pipe assembly 6, and a dust removal fan 7. The polishing chamber is fixedly mounted on the top of the central collection box 4, and the outlet of the polishing chamber is connected to the central collection box 4. The polishing assembly is installed in the polishing chamber. The drive box 5 is fixedly mounted on the outer wall of the polishing chamber and located on one side of the drive end of the polishing assembly. The drive assembly is installed in the drive box 5 and is connected to the polishing assembly in a transmission manner. The dust removal fan 7 is fixedly mounted on the top surface of the central collection box 4. A dust removal window 12 is opened on the wall of the polishing chamber. The dust removal window 12 is connected to the air inlet of the dust removal fan 7 by a dust removal pipe assembly 6 for ventilation. When a capsule is placed into the polishing chamber, the drive assembly is started to drive the polishing assembly to polish the capsule. The dust removal fan 7 operates to remove the dust generated during polishing through the dust removal pipe assembly 6. The polished capsule is pushed into the central collection box 4 by the operation of the polishing assembly for centralized storage.

[0022] The polishing chamber includes polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3, all of identical shape and size. Polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3 are all horizontally arranged and parallel to each other, forming a horizontal equilateral triangle. Polishing cylinder 1 and polishing cylinder 3 are located on the same longitudinal plane, while polishing cylinder 2 is located on another longitudinal plane, situated between polishing cylinder 1 and polishing cylinder 3 in the height direction. The discharge end of polishing cylinder 1 and the feed end of polishing cylinder 2 are on the same side, connected by a guide pipe 21. The discharge end of polishing cylinder 2 and the feed end of polishing cylinder 3 are on the same side, connected by a guide pipe 22. A feeding hopper 11 is fixedly installed above the feed end of polishing cylinder 1, and the discharge end of polishing cylinder 3 is connected to a collection box 4.

[0023] The polishing assembly includes three polishing rollers 9, which are rotatably installed in polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3, respectively. The shafts of the three polishing rollers 9 are all connected to the drive box 5 and driven by the drive assembly. When the polishing capsule is put into the feeding hopper 11, the polishing rollers 9 are driven by the drive assembly to rotate, polishing and pushing the capsule.

[0024] Dust removal windows 12 are opened at the upper ends of polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3. Three dust collection hoods are installed on the dust removal pipe assembly 6, which are aligned with the three dust removal windows 12. The three dust collection hoods are sealed and fixedly connected to the three dust removal windows 12 respectively. A dust removal rod 13 is fixedly suspended at each of the dust removal windows 12. Each dust removal rod 13 is parallel to the rotation axis of the polishing roller brush 9. The dust removal rod 13 is inserted into the bristles of the polishing roller brush 9. When the bristles of the polishing roller brush 9 rotate to the dust removal rod 13, they strike the dust removal rod 13. At the same time, the polishing roller brush 9 continues to rotate, and the bristles are moved to remove the dust. The dust removal fan 7 operates to discharge the dust. The exhaust end of the dust removal fan 7 can be connected to dust treatment equipment according to specific production needs. The dust treatment equipment needs to be purchased externally as needed.

[0025] The drive assembly includes a drive motor 51, a transmission chain 52, and three sprockets 53. The three sprockets 53 are coaxially fixed on the shafts of the three polishing rollers 9. The transmission chain 52 is fitted onto the three sprockets 53 to form a chain drive pair. The drive end of the drive motor 51 is coaxially connected to any one of the sprockets 53. When the drive motor 51 is running, it drives the three polishing rollers 9 to rotate and perform the polishing process through the chain drive pair.

[0026] Multiple deceleration ridges 14 are protruding from the inner bottom surface of both the first guide tube 21 and the second guide tube 22. Each deceleration ridge 14 is parallel to the rotation axis of the polishing roller brush 9. When the capsule exits one polishing cylinder and enters the next polishing cylinder during the polishing process, the deceleration ridges 14 increase the obstruction of the capsule's slippage process, prolonging the time the capsule stays in the first guide tube 21 and the second guide tube 22. This reduces the temperature of the capsule caused by the rolling friction polishing of the polishing roller brush 9, effectively preventing the capsule from deforming due to heat.

[0027] The discharge end of the polishing cylinder 3 is located at one end of the collection box 4. The other end of the collection box 4 is provided with a discharge opening, and a box door 8 is hinged on the discharge opening. The bottom of the collection box 4 is inclined with one end higher than the other end. A transparent observation window 81 is provided on the box door 8. Hooks 82 are hinged on both edges of the box door 8. A hooking protrusion is provided on the outer wall of the collection box 4 at the position where the two hooks 82 are aligned. When the box door 8 is closed, the two hooks 82 are hooked onto the two hooking protrusions respectively, so that the box door 8 remains in a stable closed state. The user can observe the amount of capsules in the collection box 4 through the observation window 81.

[0028] Each of the polishing roller brushes 9 has bristles arranged in a spiral shape, and the direction of rotation is set according to the direction in which the capsule moves from the feed end of polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3 towards the discharge end when the polishing roller brush 9 rotates.

[0029] The bottom of the central box 4 is equipped with multiple support legs, which raises the height of the device and makes it more comfortable to use.

[0030] Working principle: The capsules to be polished are fed into polishing cylinder 1 from the feeding hopper 11. The drive motor 51 runs and drives each polishing roller brush 9 to rotate through the chain drive pair. During the polishing process, the capsules pass through polishing cylinder 1, guide tube 21, polishing cylinder 2, guide tube 22, and polishing cylinder 3 in sequence before entering the collection box 4 for centralized storage. The polishing roller brushes 9 polish the capsules in polishing cylinder 1, polishing cylinder 2, and polishing cylinder 3 respectively. The capsules dissipate heat when passing through guide tube 21 and guide tube 22.

[0031] The dust removal fan 7 operates continuously, and the dust shaken off by the rotating polishing roller brush 9 after striking the dust removal rod 13 is sucked away by the dust removal fan 7 through the dust removal pipe group 6.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
