Description

Technical Field

[0001] The utility model relates to food and medicine packaging equipment, in particular to a tablet feeding device and a capsule filling machine. Background Art

[0002] Microtablets used to fill capsules have factors that affect the loading amount of microtablets, such as easy rolling, easy to break, and easy to generate static electricity. At present, the common ways to fill capsules with microtablets are: 1. Install a cylinder control system and a microtablet support sheet, and set a microtablet outflow hole on the microtablet support sheet. This method has a complex structure, high cost, large space occupation, and loud noise when the cylinder is working; 2. Use compressed air to blow the tablets in the metering hole. The structure is relatively compact, occupies a small space, and can speed up the flow of tablets. However, the metering method is not accurate enough and the loading amount cannot be guaranteed; 3. Use a vibrator to make the tablets fall into the feed pipe in an orderly manner, and then push them to the lower module of the capsule by the metering plate, which is conducive to ensuring accurate loading, but it takes a certain amount of time for the microtablets to enter the metering plate from the feed pipe. When multiple microtablets need to be loaded at one time, this structure has a slow production speed. Utility Model Content

[0031] Embodiment 1

[0032] Figures 1 to 6 An embodiment of the tablet feeding device of the utility model is shown. The tablet feeding device of this embodiment includes a silo 1, a metering seat 2 and a feeding seat 3 arranged in sequence from top to bottom. The feeding seat 3 is provided with a feeding guide groove 31, and the metering seat 2 is provided with a metering hole assembly. The metering hole assembly includes more than two metering holes 21 distributed along the length direction of the feeding guide groove 31. The silo 1 is provided with a drop hole assembly. The drop hole assembly includes more than two drop holes 11 distributed along the length direction of the feeding guide groove 31. The metering seat 2 is connected to a driving mechanism 4 to drive the metering hole 21 to reciprocate between the drop hole 11 and the feeding guide groove 31.

[0033] In the tablet feeding device of this embodiment, the metering hole 21 is first aligned with the drop hole 11, so that the micro-tablets in the silo 1 fall into the metering hole 21, and the state (coaxial or intersecting with the metering hole 21) and the number of micro-tablets entering the metering hole 21 are adjusted by the size and height of the metering hole 21, so as to achieve accurate metering; after the target number of micro-tablets enter the metering hole 21, the driving mechanism 4 drives the metering seat 2 to move, so that the metering hole 21 is aligned with the feed guide groove 31 below, and since each metering hole 21 of the metering hole assembly is aligned along the feed guide groove The length direction distribution of 31 makes the micro-chips in each metering hole 21 gather in the feeding guide groove 31, and finally fill the lower bag of the capsule from the feeding guide groove 31, which is beneficial to improving the feeding efficiency. Compared with the prior art, the use of height difference to achieve the transfer of micro-chips is also beneficial to reducing the fragmentation rate, and there is no need to set up a cylinder control system, a compressed air system or a feeding pipe, etc. The overall structure is simple and the cost is low. After completing a feeding action, the driving mechanism 4 drives the metering seat 2 to reset, and the metering hole 21 is aligned with the feeding hole 11 again, and the cycle is repeated.

[0034] As a preferred embodiment, multiple feed guide grooves 31 are provided and distributed along the moving direction of the metering seat 2, and multiple groups of metering hole assemblies and drop hole assemblies are provided and distributed along the moving direction of the metering seat 2, which can multiply the feeding efficiency.

[0035] Furthermore, in this embodiment, a movable guide structure is provided between the metering seat 2 and the feeding seat 3. The movable guide structure provides a guide for the reciprocating movement of the metering seat 2, ensures the movement accuracy, avoids deviation, and reduces the resistance during the movement.

[0036] Furthermore, in this embodiment, the movable guide structure includes a guide sleeve 22 provided on the metering seat 2 and a guide column 32 provided on the feeding seat 3. The guide column 32 is passed through the guide sleeve 22. The structure is simple and effective, and the displacement of the metering seat 2 during the reciprocating movement is avoided.

[0037] Furthermore, in this embodiment, the feed guide 31 is an inclined structure and the lowest point is provided with a discharge port 311. After the microchips fall into the feed guide 31, they automatically gather toward the discharge port 311 under the effect of the height difference, and are finally filled into the lower capsule of the capsule through the discharge port 311, which is structurally reasonable and effective.

[0038] Furthermore, in this embodiment, the silo 1 is connected to a vibrator 12. The vibrator 12 drives the silo 1 to vibrate, so that the micro-sheets accumulated in the silo 1 enter the drop holes 11 in an orderly manner, and the structure is reasonable and effective.

[0039] Furthermore, in this embodiment, a support plate 5 is provided on opposite sides of the silo 1, a chute 51 is provided on the support plate 5, and a convex portion 13 extending into the chute 51 is provided on the silo 1. Micro-chip fragmentation usually occurs when the micro-chip enters the metering seat 2 from the silo 1 and enters the feeding seat 3 from the metering seat 2. The convex portion 13 cooperates with the chute 51 to form a drawer-type structure, which can realize the positioning of the silo 1 in the up-down and left-right directions on the one hand, and when fragments occur, the silo 1 can be drawn out of the support plate 5 for processing, which has a reasonable structure and is convenient to use.

[0040] Furthermore, in this embodiment, the silo 1 and the support plate 5 are connected by threaded fasteners (not shown in the figure, for example, bolts, screws, etc.). The threaded fasteners can be used to effectively fix the silo 1 and the support plate 5, and the silo 1 can be positioned in the front and rear directions. When the silo 1 needs to be pulled out to process the debris, the threaded fasteners can be loosened.

[0041] Furthermore, in this embodiment, the driving mechanism 4 includes a cam block 41 and a lifting driving member 42 (for example, a cylinder, an electric cylinder or a synchronous belt mechanism, etc.) for driving the cam block 41 to rise and fall. The cam block 41 is provided with a cam groove 411, and the metering seat 2 is provided with a rolling member 23, and the rolling member 23 is positioned in the cam groove 411. During operation, the lifting driving member 42 drives the cam block 41 to rise and fall, and the cam groove 411 on the cam block 41 pushes the rolling member 23 to move back and forth during the lifting and falling process, thereby realizing the reciprocating movement of the metering seat 2, which is conducive to ensuring the repeated positioning accuracy during the reciprocating movement of the metering seat 2. The friction resistance between the rolling member 23 and the cam groove 411 is small, which is conducive to ensuring the smooth lifting and falling process of the cam block 41, and the structure is reasonable and effective.

The capsule filling machine of this embodiment comprises a turntable 6 and a plurality of capsule molds 7 arranged along the circumference of the turntable 6. Two tablet feeding devices are arranged on the side of the turntable 6. Of course, in other embodiments, as the number of capsules on the capsule mold 7 changes, the number of tablet feeding devices can also be adjusted accordingly.

[0044] The capsule filling machine of this embodiment includes the above-mentioned tablet feeding device, and thus also has the above-mentioned advantages; more than two tablet feeding devices can simultaneously fill capsules in different rows of the capsule mold 7, which is beneficial to improving the filling efficiency.
