Abstract
Description
Technical Field
[0001] This utility model relates to the field of tablet presses, and in particular to a tablet press feeding device. Background Technology
[0002] An existing patent (publication number: CN218701626U) discloses a feeding device for a tablet press, including a feeding seat. The lower end of the feeding seat is connected to a feeding pipe, and an anti-powder-falling component is connected to one side of the feeding pipe. A cleaning component is connected to one side of the upper end of the feeding seat. A first motor drives a concave rod to rotate, so that the sealing ball is no longer sealed to the feeding pipe, thereby allowing the material inside the feeding seat to be discharged. However, this device "further removes the sealing ball from the feeding pipe, so that the sealing ball is no longer sealed to the feeding pipe, thereby allowing the material inside the feeding seat to be discharged" controls the material discharge time by controlling the opening and closing time of the sealing ball, thereby controlling the amount of material discharged. The amount discharged each time is difficult to control precisely, thus affecting the overall feeding effect. Summary of the Invention
[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a tablet press feeding device where, during the feeding operation of a tablet press, when the quantitative feeding groove of the quantitative feeding wheel aligns with the upper feed pipe, the powder stored in the powder storage tank falls into the corresponding quantitative feeding groove. Simultaneously, the dial drive motor controls the rotation of the quantitative feeding wheel via the active dial and groove wheel connection mechanism, causing the quantitative feeding groove to gradually rotate until it aligns with the lower feed pipe. The powder inside the quantitative feeding groove is then discharged, completing one feeding operation. Each feeding operation involves the same amount of powder added as the volume inside the quantitative feeding groove, resulting in more precise control and better feeding effect.
[0004] The objective of this utility model is achieved through the following technical solution:

[0006] The inclined lifting platform has a vertical surface corresponding to the quantitative feeding groove, the knocking block is matched with the knocking groove, the knocking block is connected with the knocking groove, the knocking block slides in the knocking groove, the knocking block top has a knocking block positioning column, one side of the feeding mechanism mounting table has an inner protective cover connecting table, the feeding mechanism mounting table is connected with the outer protective cover on the side corresponding to the inner protective cover connecting table, the outer protective cover has outer protective cover connecting tables on both sides, and the outer protective cover connecting tables are connected with the inner protective cover connecting table through screws.
[0007] The outer protective cover has a knocking block mounting table in the middle, the knocking block mounting table has a knocking block positioning groove in the middle, the knocking block positioning groove is matched with the knocking block positioning column, the knocking block positioning groove is connected with the knocking block positioning column, the knocking block positioning column slides in the knocking block positioning groove, the knocking block is connected with the knocking block mounting table through a spring, and the knocking block is pressed on the surface of the knocking groove.
[0008] Beneficial effects: 1. When the quantitative feeding wheel has a quantitative feeding groove corresponding to the upper feeding pipe, the powder stored in the powder storage groove falls into the corresponding quantitative feeding groove, the quantitative feeding wheel is controlled to rotate by the driving dial and the groove wheel connecting mechanism of the dial driving motor, the quantitative feeding groove is gradually rotated to correspond to the lower feeding pipe, the powder in the quantitative feeding groove is discharged at this time, and one feeding operation is completed. The amount of feeding each time is equal to the volume of the quantitative feeding groove, and the control is more accurate and the feeding effect is better.
[0009] 2. The knocking block and the knocking block mounting table are connected through a spring, and when the quantitative feeding groove corresponds to the lower feeding pipe, the knocking block slides to the knocking groove from the top of the inclined lifting platform, and one knocking is completed. Through this knocking, part of the powder adhered in the quantitative feeding groove directly below is shaken off, and the residual powder in the quantitative feeding groove does not affect the accuracy of the feeding process.
[0010] 3. The knocking block is provided with a vertical surface on one side, so that the knocking block can not be hindered by the inclined lifting platform during the process of approaching the knocking groove after being disconnected from the inclined lifting platform, and the impact degree of the knocking process is ensured.
[0011] 4. The wheel groove mechanism is adopted between the groove wheel and the driving dial, so that the quantitative feeding wheel can stop for a period of time after rotating 60° each time, so that the device has enough time to load the powder into the quantitative feeding groove and discharge the powder from the quantitative feeding groove, and the accuracy of each feeding is further increased.
