Description

Technical Field

[0001] This utility model belongs to the field of capsule processing, and in particular relates to a capsule polishing machine that prevents cell wall breakage. Background Technology

[0002] Capsule polishing machines are key auxiliary equipment in the production of capsules in the pharmaceutical and health product industries. Their core function is to remove impurities such as dust and oil from the surface of capsules, improve the cleanliness of the product's appearance and quality stability, and at the same time, they can help separate broken capsules and debris generated during the polishing process.

[0003] In practical applications, the rotation direction of the brushes in existing capsule polishing machines is mostly fixed. When the rotation direction of the brushes is opposite to the direction of capsule feeding, the two will form a reverse force, causing the capsules to be forcibly blocked and rubbed by the brushes during the feeding process. This not only reduces polishing efficiency, but also causes capsule shell damage due to excessive local force, especially for thin soft capsules or irregularly shaped capsules.

[0004] Meanwhile, during the polishing process of the capsules, because the inner cylinder is fixedly installed, if there are many capsules piled up in one place while the brush is rotating, the capsules will come into contact with the inner wall of the inner cylinder and cause compression, which can easily lead to cell wall breakage.

[0005] Therefore, there is an urgent need to develop a capsule polishing machine that can prevent capsules from being squeezed against the inner wall and ensure that the direction of capsule feeding is consistent with the direction of brush rotation to prevent cell wall breakage. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a capsule polishing machine that can prevent the capsule from being squeezed against the inner wall and ensure that the direction of capsule feeding is consistent with the direction of brush rotation to prevent cell wall breakage.

[0007] The technical solution is as follows: A capsule polishing machine to prevent cell wall breakage includes a mounting bracket, an outer cylinder, a discharge pipe, a hopper, polishing brushes, a motor, an inner cylinder, a conveying spiral blade, a dust collector, and a suction pipe. The outer cylinder is installed on the top of the bracket, and the outer cylinder is installed at an angle with the left side lower than the right side. The discharge pipe is located on the bottom right side of the outer cylinder, and the hopper is located on the top left side of the outer cylinder. The hopper has a feeding mechanism to change the direction of capsule feeding. The inner cylinder is coaxially installed on the inner wall of the outer cylinder through a flexible material. The inner cylinder has a dust outlet hole that communicates with the outer cylinder. Impurities generated during polishing are discharged through the dust outlet hole. The polishing brush is installed inside the outer cylinder along its axial direction. The polishing brush is inside the inner cylinder. The inner wall of the inner cylinder is provided with a conveying spiral blade. The conveying spiral blade cooperates with the rotating polishing brush to convey the capsules from left to right. The motor is located on the right side of the outer cylinder. The output shaft of the motor is connected to the right end of the polishing brush. The dust collector is fixedly connected to the lower part of the mounting bracket. The dust collector is connected to the lower left side of the outer cylinder through a suction pipe.

[0008] Furthermore, the inner wall of the outer cylinder is connected to the inner cylinder by a flexible pad, which is an air bladder. By changing the inflation volume of the air bladder, the tightness of the fixation between the inner cylinder and the outer cylinder can be changed.

[0009] Furthermore, the outer cylinder is divided into two chambers, left and right. The left chamber is the polishing chamber, and the motor is installed in the right chamber of the outer cylinder.

[0010] Furthermore, the feeding mechanism includes a feeding plate and a deflecting plate. The feeding plate is rotatably mounted in the lower part of the hopper via a shaft and a torsion spring. The shaft that rotatably mounts the feeding plate passes through the left wall of the hopper and is connected to the deflecting plate. The direction of the feeding plate can be changed by the deflecting plate.

[0011] Furthermore, it also includes an air cushion. An air cushion is installed at the bottom of the discharge pipe. When the polished capsule is discharged through the discharge pipe, the capsule falls on the air cushion to prevent the capsule from being damaged.

[0012] Furthermore, the interior of the polishing brush is hollow to reduce its weight.

[0013] Furthermore, it also includes an air inlet pipe and an air blowing nozzle. The polishing brush is provided with an air blowing nozzle along its circumference, and the left side of the polishing brush is connected to the dust collector by an air inlet pipe.

[0014] The beneficial effects of this utility model are as follows: This utility model changes the dropping direction of the capsules by using a feeding plate. The dropping direction of the capsules is exactly the same as the rotation direction of the polishing brush, so that the capsules will not be broken due to the reverse force during the dropping process. If the capsules accumulate in the inner cylinder, because the flexible pad is an air bladder, the inner cylinder has space to shift within the outer cylinder, so that the capsules will not be damaged due to partial accumulation during the polishing process.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Please refer to the following: Figures 1-4 This invention provides a capsule polishing machine for preventing cell wall breakage. The aforementioned capsule polishing machine includes a mounting bracket 1, an outer cylinder 2, a discharge pipe 21, a hopper 3, polishing brushes 4, a motor 5, an inner cylinder 6, a conveying spiral blade 8, a dust collector 9, and a suction pipe 10. The outer cylinder 2 is bolted to the top of the bracket and is installed at an angle with the left side lower than the right. The discharge pipe 21 is located on the bottom right side of the outer cylinder 2, and the hopper 3 is located on the top left side of the outer cylinder 2. The hopper 3 has a feeding mechanism that changes the direction of capsule feeding. The inner cylinder 6 is coaxially mounted on the inner wall of the outer cylinder 2 using a flexible material. The flexible pad 61 is an air bladder; by changing the inflation volume of the air bladder, the tightness of the fixation between the inner cylinder 6 and the outer cylinder 2 can be changed. The inner cylinder 6 has a dust outlet 7 communicating with the outer cylinder 2, through which impurities generated during polishing are discharged. Polishing brushes 4 are installed inside the outer cylinder 2 along its axial direction. The polishing brush 4 is located inside the inner cylinder 6. The interior of the polishing brush 4 is hollow to reduce its weight and the burden on the motor 5. The inner wall of the inner cylinder 6 is equipped with a conveying spiral blade 8, which works in conjunction with the rotating polishing brush 4 to transport the capsule from left to right. The outer cylinder 2 has two chambers, left and right. The left chamber is the polishing chamber. The motor 5 is installed in the right chamber of the outer cylinder 2. The output shaft of the motor 5 is connected to the right end of the polishing brush 4. The motor 5 controls the rotation direction and speed of the polishing brush 4. The lower part of the mounting bracket 1 is fixedly connected to the dust collector 9 by bolts. The dust collector 9 is connected to the lower left part of the outer cylinder 2 by a suction pipe 10. During the capsule polishing process, the dust collector 9 is controlled to work and suck away the dust generated during polishing. At the same time, the outer cylinder 2, which is installed at an angle with the left side lower than the right side, is also more conducive to dust cleaning.

[0022] In a preferred embodiment, the above-mentioned feeding mechanism can employ... Figure 4 The structure shown includes a feeding plate 31 and a deflecting plate 32. The feeding plate 31 is rotatably mounted in the lower part of the hopper 3 via a shaft and a torsion spring. The shaft that rotatably mounts the feeding plate 31 passes through the left wall of the hopper 3 and is connected to the deflecting plate 32. The direction of the feeding plate 31 can be changed by the deflecting plate 32, thereby changing the feeding direction of the capsule.

[0023] This embodiment provides a capsule polishing machine to prevent cell wall breakage. Compared with the prior art, when polishing capsules using this device, firstly, the motor 5 is controlled to rotate counterclockwise, which in turn drives the polishing brush 4 to rotate counterclockwise. Then, the capsule is placed in the hopper 3. Subsequently, the actuating plate 32 is rotated counterclockwise, causing the discharge plate 31 to rotate counterclockwise. The rear part of the discharge position of the hopper 3 is opened, and the capsule falls into the inner cylinder 6 through the opened position. Because the polishing brush 4 rotates counterclockwise, the capsule slides down along the rear side wall of the inner cylinder 6. In this way, the direction of capsule falling is exactly the same as the direction of rotation of the polishing brush 4, so that the capsule will not break due to the reverse force during the falling process. After the capsule falls into the inner cylinder 6, the polishing brush 4 polishes the capsule in the inner cylinder 6. Polishing is performed, and during the rotation of the polishing brush 4, the capsules are conveyed to the right for polishing due to the action of the conveying spiral blade 8. If the capsules accumulate in the inner cylinder 6, the flexible pad 61 is an airbag, and the inner cylinder 6 has space to shift within the outer cylinder 2, so that the capsules will not be damaged due to partial accumulation during the polishing process. After polishing, the capsules are discharged through the discharge pipe 21. During the polishing process, the dust collector 9 is started to work. Impurities generated during the polishing process are discharged through the dust outlet 7 and then sucked into the dust collector 9 along the inclined surface of the outer cylinder 2 and the air inlet pipe 11 for collection. After the capsules are polished, the motor 5 and the dust collector 9 are stopped, and the feeding plate 31 is reset by the actuating plate 32.

[0024] In a preferred embodiment, it can be adopted Figure 2 The structure shown also includes an air cushion 13. An air cushion 13 is installed at the bottom of the discharge pipe 21. When the polished capsule is discharged through the discharge pipe 21, the capsule falls on the air cushion 13 to prevent the capsule from being damaged.

[0025] In a preferred embodiment, it can be adopted Figure 4 The structure shown also includes an air inlet pipe 11 and an air blowing nozzle 12. The polishing brush 4 is provided with an air blowing nozzle 12 along its circumference. The left side of the polishing brush 4 is connected to the dust collector 9 by the air inlet pipe 11. During the polishing of the capsule, gas is injected into the polishing brush 4 through the air inlet pipe 11. The gas is sprayed out through the air blowing nozzle 12 to blow away the accumulated capsules. It can also be used to assist in polishing.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
