Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding technology for drying, and in particular to a feeding device for drying wet tablets and granules. Background Technology
[0002] In the pharmaceutical industry, drying wet tablets and granules is a crucial step in formulation production. During the drying process, wet granules are prone to clumping due to residual moisture or material properties. If they cannot be dispersed in time, it will lead to uneven drying, increased energy consumption, and even affect the final drug quality. Traditional drying equipment often relies on static conveying or simple mechanical pushing, which is insufficient to effectively solve the problem of granule clumping.
[0003] In existing technologies, the conveying and drying of wet tablet granules typically employs a fixed conveyor belt or a spiral pushing mechanism. A fixed conveyor belt, driven by a motor, moves the belt at a constant speed, transporting the wet granules from the inlet to the drying area; a spiral pushing mechanism uses rotating blades to propel the material forward. Additionally, some equipment uses an external vibrating motor or airflow to achieve particle dispersion, but the vibrating motor is usually installed independently outside the conveyor belt, resulting in insufficient contact with the material, while airflow dispersion can introduce impurities or cause particle splashing.
[0004] However, existing technologies have a significant drawback: due to the lack of an integrated dynamic vibration mechanism during the conveying process, wet granules are prone to agglomeration on the conveyor belt due to compression or moisture adhesion. For example, fixed conveyor belts rely solely on friction to push the material, which cannot effectively break up agglomerates; external vibration motors, due to limited installation locations, cannot accurately transmit vibration to the material layer. To address these issues, a pushing device for drying wet tablet granules is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a feeding device for drying wet tablet granules, which aims to improve the problem in the prior art where the lack of a vibration mechanism during tablet conveying causes the clumped wet tablet granules to be unable to disperse.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A feeding device for drying wet tablets and granules includes a connecting pipe, a protective cover fixedly connected to one end of the connecting pipe, a driving component provided on the side wall of the protective cover, an L-shaped connecting plate fixedly connected to the bottom of the protective cover, a second motor fixedly connected to the side wall of the L-shaped connecting plate, and a rotating wheel fixedly connected to the output end of the second motor. A vibration component is provided on the side wall of the rotating wheel.
[0008] The vibration assembly includes a second rotating column, the side wall of which is fixedly connected to the side wall of the rotating wheel. A third connecting plate is rotatably fixedly connected to the outer wall of the second rotating column. A first connecting plate is rotatably connected inside the third connecting plate. A first rotating column is rotatably connected inside the first connecting plate. One end of the first rotating column is fixedly connected to the side wall of the L-shaped connecting plate. A second connecting plate is rotatably connected to the outer wall of the first connecting plate. A connecting rod is rotatably connected inside the second connecting plate. One end of the connecting rod is fixedly connected to a rotating shaft.
[0009] As a further description of the above technical solution:
[0010] The drive assembly includes a second connecting frame, the side wall of which is fixedly connected to the side wall of the protective cover. A first motor is fixedly connected inside the second connecting frame, and a conveyor belt is fixedly connected to the output end of the first motor. The side wall of the conveyor belt is disposed inside the protective cover, and the outer wall of the rotating shaft is disposed inside the inner wall of the conveyor belt.
[0011] As a further description of the above technical solution:
[0012] The bottom of the protective cover is fixedly connected to a base, the side wall of the protective cover is fixedly connected to a diagonal brace, the top of the diagonal brace is fixedly connected to a first support plate, and the top of the first support plate is fixedly connected to a second support plate.
[0013] As a further description of the above technical solution:
[0014] The second support plate has a brush on its side wall, and the brush side wall is located on the outer wall of the conveyor belt.
[0015] As a further description of the above technical solution:
[0016] The brush has a first connecting frame inside, and a rotating disk is rotatably connected inside the first connecting frame.
[0017] As a further description of the above technical solution:
[0018] The rotating disk has a fixedly connected turntable inside, and the rotating disk has a hollow groove inside.
[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the rotating wheel drives the second rotating column to rotate, which in turn drives the first connecting plate to rotate. The first connecting plate then drives the second connecting plate and the connecting rod to rotate, causing the rotating shaft to sway. This achieves the effect of a vibrating conveyor belt, solving the problem that when tablets are being transported, the lack of a vibration mechanism prevents the clumping of wet tablet granules from being dispersed. This improves the practicality of the pusher device for drying wet tablet granules.
[0025] 2. In this utility model, by rotating the turntable, the turntable is driven to rotate, and then the locking pin is driven to rotate, and then the locking pin is disengaged from the inside of the brush, thus achieving the effect of disassembling the brush. This solves the problem that the brush cannot be quickly disassembled, which leads to a longer disassembly time during cleaning and maintenance, and improves the convenience of the feeding device for drying wet tablets and granules.
