Abstract
Description
Technical Field
[0001] This utility model relates to the field of tablet manufacturing technology, and in particular to a feeding device for tablet manufacturing. Background Technology
[0002] Tablets are solid dosage forms that are formed by uniformly mixing drugs with suitable excipients and then compressing them into round or irregularly shaped tablets. They are the most common type of modern drug dosage form. Preparing drugs into tablets makes them easier to swallow and allows for controlled dosage.
[0003] In actual production, the feeding hopper is installed on the corresponding tablet press for feeding, and the tablets are pressed into tablets by the tablet press. The tablets are then ejected and collected.
[0004] However, when the feeding hopper discharges material, if the material particles are irregular in shape and vary greatly in size, small particles may fill the gaps between larger particles, resulting in poor overall material flowability and forming an arch-like structure that blocks the flow of subsequent material, causing blockage. When a blockage forms, manual cleaning and unblocking operations are required. Manually cleaning the blockage requires stopping the operation of the feeding hopper and related equipment, opening the corresponding parts of the equipment (such as outlet valves, pipe connections, etc.), and using tools (such as shovels, brushes, etc.) to remove the blockage bit by bit, which is quite troublesome. Therefore, a feeding device for tablet production is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a feeding device for tablet production, which aims to improve the problem of the cumbersome manual cleaning and unblocking of the feeding hopper outlet in the prior art.

A worm is fixedly connected to the bottom end of the rotating column, the outer arc surface of which is rotatably connected to the inner wall of the positioning block. The right end of the worm meshes with the left end of the worm gear.
[0012] As a further description of the above technical solution:
[0013] The rear end of the elliptical plate is fixedly connected to the front end of the worm gear, and the top end of the support column is fixedly connected to the bottom end of the worm.

[0022] This utility model has the following beneficial effects:
[0023] 1.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of a feeding device for tablet production, including a feeding barrel 1. A valve is provided on the inner wall of the bottom end of the feeding barrel 1 to control the discharge of the material to be processed. The bottom end of the feeding barrel 1 can be installed on a tablet press. The installation operation is prior art and will not be explained in detail here. A clearing mechanism 2 is provided at the top of the feeding barrel 1. The clearing mechanism 2 can clear the bottom of the feeding barrel 1 to prevent blockage. The clearing mechanism 2 includes a motor 201, and a rotating column 202 is fixedly connected to the output end of the motor 201. The output end of the motor 201 drives the rotating column 202 to rotate, thus avoiding manual clearing. A positioning block 210 is fixedly connected to the inner side wall of the feeding barrel 1. Columns are provided at both ends of the positioning block 210 for easy connection. A connecting component is provided on the inner wall of the positioning block 210. An elliptical plate 203 is rotatably connected to the front end of the positioning block 210. The movement of the connecting components causes the elliptical plate 203 to rotate, thereby achieving the purpose of unblocking. A support column 207 is rotatably connected to the bottom end of the positioning block 210. A conical plate 206 is fixedly connected to the bottom outer wall of the support column 207. The rotation of the support column 207 can cause the conical plate 206 to rotate, thereby improving the unblocking effect. A movable seat 204 is slidably connected to the top outer arc surface of the support column 207. The top of the movable seat 204 is provided with an inclined surface, and the bottom is cylindrical. The inclined surface facilitates the downward discharge of materials. A dispersing plate 208 is rotatably connected to the bottom outer arc surface of the movable seat 204. Multiple sets of dispersing plates 208 are provided, and they can move closer together to perform dispersing and unblocking operations. A stirring mechanism 3 is provided at the top of the positioning block 210 to ensure that the materials are uniform.
[0033] Reference Figures 1-3 The bottom end of the motor 201 is fixedly connected to the top end of the feeding hopper 1, which supports the motor 201. The top end of the rotating column 202 is rotatably connected to the inner wall of the top end of the feeding hopper 1, and the bottom end of the rotating column 202 is rotatably connected to the inner wall of the top end of the positioning block 210. The rotational arrangement drives the unblocking mechanism 2 to move, avoiding manual unblocking. The connecting component includes a worm gear 212, the center of which is rotatably connected to the inner wall of the positioning block 210. The two move along the same trajectory. The bottom end of the rotating column 202 is fixedly connected to a worm 211, the outer arc surface of which is rotatably connected to the inner wall of the positioning block 210. The right end of the worm 211 meshes with the left end of the worm gear 212. The rotation of the worm 211 drives the worm gear 212 to rotate.
[0034] Reference Figures 1-3The rear end of the elliptical plate 203 is fixedly connected to the front end of the worm gear 212, and their movement trajectories are consistent. The top end of the support column 207 is fixedly connected to the bottom end of the worm gear 211, and the rotation setting avoids movement interference. The top end of the movable seat 204 contacts the bottom end of the elliptical plate 203, and the contact between the two allows the movable seat 204 to move downward. The outer wall of the dispersing plate 208 is rotatably connected to the bottom outer arc surface of the support column 207, and the connection point is the rotation center. The movable seat 204 and the support column 207 are connected by an elastic telescopic rod 205. One end of the elastic telescopic rod 205 is fixedly connected to the bottom end of the movable seat 204, and the other end of the elastic telescopic rod 205 is fixedly connected to the bottom outer wall of the support column 207. The elastic telescopic rod 205 is composed of two sets of sleeve rods that are interlocked, and they can slide relative to each other to change its overall length. In addition, the elastic telescopic rod 205 has a built-in spring, which gives it a certain elasticity. The elasticity of the elastic telescopic rod 205 enables the movable seat 204 to have a reset function.
[0035] Reference Figures 2-4 The stirring mechanism 3 includes a positioning column 301, on which a second bevel gear 303 is fixedly connected. The positioning column 301 can support the second bevel gear 303. A flap 304 is rotatably connected to the outer wall of the rotating column 202. The rotation of the flap 304 improves the stirring effect. A first bevel gear 302 is fixedly connected to one end of the flap 304 near the second bevel gear 303. The rotation of the first bevel gear 302 drives the flap 304 to rotate. The bottom end of the positioning column 301 is fixedly connected to the top end of the positioning block 210. The bottom end of the first bevel gear 302 meshes with the top end of the second bevel gear 303. The meshing of the two allows the flap 304 to rotate together with the first bevel gear 302 when it rotates.
[0036] Working principle: When material needs to be fed, the bottom of the feeding hopper 1 is first installed on the corresponding tablet press. Then, the motor 201 is started, causing the output end of the motor 201 to rotate, which in turn drives the rotating column 202 to rotate. The rotation of the rotating column 202 drives the worm gear 211 to rotate, causing the worm wheel 212 to rotate. At this time, the elliptical plate 203 also rotates. When the elliptical plate 203 rotates to the bottom, it contacts and squeezes the top inclined surface of the movable seat 204, causing the movable seat 204 to move downward. When the movable seat 204 moves downward, it drives multiple sets of dispersing plates 208 to move inward. When the elliptical plate 203 is no longer in contact with the inclined surface of the movable seat 204, the elasticity of the elastic telescopic rod 205 causes the movable seat 204 to return to its original position. This disperses and clears the material near the feeding hopper 1. The rotation of the worm gear 211 drives multiple sets of conical plates 206 to rotate, thereby improving the clearing effect and avoiding blockages, thus avoiding manual cleaning.
[0037] When the rotating column 202 rotates, it will drive multiple sets of flaps 304 to rotate (rotate around the center of the rotating column 202). The rotation of the flaps 304 will drive the first bevel gear 302 to rotate. Since the first bevel gear 302 meshes with the second bevel gear 303, the second bevel gear 303 will rotate, which will cause the flaps 304 to rotate, thereby improving the stirring effect.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
