[0002] In the field of pharmaceutical manufacturing, capsules, as a common form of drug packaging, their appearance quality has an important impact on the overall image of the drug and the acceptance of patients. Capsule polishing is an important link in the capsule production process. It can not only improve the appearance gloss of the capsule, but also remove impurities and fine particles that may adhere during the production process, ensuring the cleanliness and safety of the capsule. However, traditional capsule polishing machines often face problems such as raw material accumulation and uneven feeding during the feeding process, which not only affects the polishing efficiency, but also may cause unnecessary damage to the capsules.

[0003] In the prior art, the feeding process of capsule polishing machines mostly relies on manual operation, that is, the capsules to be polished are manually fed into the polishing machine, which is likely to cause uneven feeding and affect the polishing effect; resulting in raw material accumulation, causing poor feeding and even blocking the feeding channel; at the same time, the efficiency is low, and during the manual operation process, the operator is easily exposed to harmful substances such as high-speed rotating parts or dust, posing certain safety hazards.

[0004] The existing feeding equipment has complex operations, cannot be matched with all models of capsule polishing machines for use, has a narrow application range, and high costs. Summary of the Utility Model

[0027] The sliding mechanism 3 includes a plurality of sliding rods 31 vertically arranged at the edge position of the bottom plate 1, and the plurality of sliding rods 31 are arranged in a square array along the edge of the bottom plate 1.

[0028] The same sliding plate 33 is slidably installed on the sliding rods 31, and bearings 32 are fixedly installed at the positions where the sliding plate 33 is connected to each sliding rod 31.

[0029] All the sliding rods 31 penetrate through the corresponding bearings 32. With such a design, the sliding plate 33 slides on the sliding rods 31.

[0030] The power output end of the electric push rod 2 is fixedly connected to the sliding plate 33, that is, the electric push rod 2 drives the sliding plate 33 to slide on the sliding rods 31 to adjust the height of the sliding plate 33.

[0031] The screw pump assembly 4 includes a mounting bracket 42 fixedly installed at one end position of the sliding plate 33, and a screw pump 41 is fixedly installed on the mounting bracket 42.

[0032] The screw pump 41 can push and extrude the conveying medium axially through the eccentric rotation of the screw in the pump casing, realizing the stable conveyance of the conveying medium. Its specific working principle is already well-known in the prior art and will not be elaborated here in detail. Moreover, the screw pump 41 can be purchased from the market.

[0033] A first feed port 43 is communicated at the middle position of the screw pump 41, and a first discharge port 44 is arranged at one end of the screw pump 41 close to the conveying mechanism 5.

[0034] The conveying mechanism 5 includes a protective cover 51 fixedly installed on the sliding plate 33 at a position close to the first discharge port 44. The protective cover 51 is made by welding multiple stainless steel plates with different lengths.

[0035] The first discharge port 44 extends into the protective cover 51.

[0036] The same conveyor belt 52 is fixedly installed on both inner side walls of the protective cover 51, and one end of the conveyor belt 52 is located below the first discharge port 44.

[0037] With such a design, the material output from the first discharge port 44 falls onto the conveyor belt 52.

[0038] The area between the end of the protective cover 51 far from the first discharge port 44 and the conveyor belt 52 is set as a second discharge port 53. The end of the protective cover 51 far from the first discharge port 44 is located outside the edge of the sliding plate 33, that is, the second discharge port 53 is located outside the edge of the sliding plate 33.

[0039] With such a design, the material on the conveyor belt 52 is output from the second discharge port 53.

[0040] In this embodiment, the conveying principle of the conveyor belt 52 in the prior art is already well-known and will not be elaborated here in detail. The conveyor belt 52 can be directly purchased from the market.

[0042] An installation plate 64 is fixedly installed on the bracket 61, and a hopper 62 is fixedly installed on the installation plate 64. The hopper 62 penetrates through the installation plate 64 at the same time.

[0043] A second feed port 63 is opened on the upper surface of the hopper 62. A sealing cover is arranged on the second feed port 63, not marked in the figure. The function of the sealing cover is to prevent dust in the surrounding environment from falling into the hopper 62.

[0044] The lower part of the hopper 62 is funnel-shaped to facilitate material discharging, and the outlet end of the funnel under the hopper 62 is connected to a material conveying pipe 65.

[0045] The material conveying pipe 65 is connected to the first feeding port 43 through a flexible pipe 66.

[0048] During use, place the automatic feeding device of the capsule polishing machine at the position of the material inlet of the capsule polishing machine, control the start of the electric push rod 2, and the power output end of the electric push rod 2 drives the sliding plate 33 to slide up and down along the sliding rod 31. According to the height of the material inlet of the capsule polishing machine, make the second discharge port 53 located above the material inlet of the polishing machine to complete the position adjustment before feeding;

[0049] Put all the capsules to be polished into the hopper 62 from the second feeding port 63. Under the action of the hopper 62, the capsules to be polished gather at the position of the first feeding port 43. Adjust the rotation speed of the motor of the screw pump 41, and then control the conveying speed of the screw pump 41. Start the screw pump 41, and the capsules at the position of the first feeding port 43 can be conveyed to the position of the first discharge port 44 at the conveying speed of the screw pump 41. At the same time, adjust the conveying speed of the conveyor belt 52 to make the conveying speed of the conveyor belt 52 match that of the screw pump 41. Then the capsules output from the first discharge port 44 fall onto the conveyor belt 52. In this way, it can ensure that the capsules are evenly scattered on the conveyor belt 52. Under the action of the conveyor belt 52, the capsules to be polished evenly fall into the material inlet of the polishing machine and do not accumulate, and finally the capsules are polished.

[0050] When this device is applied to other capsule polishing machines with different heights, only need to control the electric push rod 2 to adjust the height of the sliding plate 33. The operation is convenient and it has a wide application range.

[0051] At the same time, this device can also be directly connected to the capsule production line, completely realizing the automation of capsule production. Just connect the capsule output pipe through the second feeding port 63. Under the control of the screw pump 41 and the conveyor belt 52, the polishing of the capsules is completed, further expanding the application range.

[0052] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and deformations made to the embodiments still fall within the protection scope of the present invention.
