Description

Technical Field

[0001] This utility model relates to the field of tablet press technology, and in particular to a rotating mechanism for a drug tablet press. Background Technology

[0002] In the pharmaceutical manufacturing process, pulverized raw materials typically need to be compacted to form tablets. Modern tableting machines, under the action of a feeder, introduce powdered drug into the tableting cavity. Then, by activating the tableting mechanism, the press head compacts the powdered drug within the cavity, thus forming tablets. After compression, the tablets are automatically unloaded by an automatic feeding mechanism.

[0003] However, most existing high-speed drug tablet presses use a cleaning rod to clean the pressed tablets. Since the tablets are moved by the cleaning rod immediately after pressing, they are affected by impact, making them easy to loosen or damage the surface, thus reducing the quality of the finished product. In view of this, we propose a rotating mechanism for a drug tablet press. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a rotating mechanism for a drug tableting machine.

[0005] The technical solution of this utility model: A rotating mechanism for a drug tableting machine includes a processing table, a controller installed on the front wall of the processing table, a support frame connected to the side wall of the processing table, a feeding assembly connected to the top of the support frame, a collection box inserted into the inlet of the front wall of the processing table, second buffer blocks symmetrically installed on the inner wall of the processing table, a first buffer block disposed between the two second buffer blocks, a rotating assembly installed on the top wall of the processing table, the rotating assembly including a support plate, a feeding tray disposed below the support plate, an annular transparent cover disposed above the feeding tray, a support block disposed on the outer surface wall of the feeding tray, a first motor and a hydraulic cylinder installed on the top wall of the support plate, and a pressure head (28) sleeved at the output end of the hydraulic cylinder.

[0006] Preferably, the inner arc surfaces of the four support blocks are fixedly connected to the outer surface wall of the annular transparent cover, and the support blocks are installed at the top opening of the feeding tray cavity.

[0007] Preferably, the output end of the first motor is connected to a first rotating shaft, and a through hole is provided in the middle part of the feeding tray, into which the bottom end of the first rotating shaft is inserted.

[0008] Preferably, each of the four support blocks has an arc-shaped groove on its inner arc-shaped wall, and a guide ring is fitted onto the outer surface wall of the feeding disc, with part of the guide ring structure disposed in the arc-shaped groove.

[0009] Preferably, the bottom wall of the support plate is welded with reinforcing ribs, and the top wall of the reinforcing ribs and the top wall of some of the support blocks are connected to the bottom wall of the support plate.

[0010] Preferably, the feeding assembly includes a feeding pipe, a hopper is intercepted at the top opening of the feeding pipe, a second motor is installed on the side wall of the feeding pipe, the output end of the second motor is connected to a second rotating shaft, and an auger is sleeved on the outer surface wall of the second rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This invention achieves automatic feeding by starting a second motor to drive a second rotating shaft, which in turn drives an auger to rotate. Under the drive of a first motor, the first rotating shaft drives the feeding disc to deliver the powder to the area below the pressing head, thereby activating a hydraulic cylinder to push the pressing head down, achieving the purpose of tableting the powder. The different diameter settings on the feeding disc allow for timely adjustments based on the tablet production size, improving the flexibility and applicability of the equipment. Simultaneously, the rotation allows the finished tablets to pass through the first and second buffer blocks and be guided into the collection box for collection, reducing the risk of drug breakage caused by conventional feeding and improving feeding safety.

[0019] Example

[0020] like Figures 1 to 4 As shown, the present invention discloses a rotating mechanism for a drug tableting machine, comprising a processing table 1 and a controller 9. The controller 9 is fixedly installed on the front wall of the processing table 1 for easy operation by the operator. The processing table 1 is equipped with a rotating assembly 2, which includes a support plate 21, a first motor 22, a first rotating shaft 23, a feeding disc 24, a guide ring 25, a support block 26, a hydraulic cylinder 27, a pressing head 28, and reinforcing ribs 29. Four reinforcing ribs 29 are symmetrically installed on the bottom wall of the support plate 21, and the opposite walls of the four reinforcing ribs 29 are fixedly connected to the front wall and the back wall of the processing table 1, providing support for the support plate 21. Four support blocks 26 are installed in a circular array on the top wall of the processing table 1, and the top walls of two of the support blocks 26 are fixedly connected to the bottom wall of the support plate 21, also providing support for the support plate 21.

[0021] The first motor 22 is fixedly mounted on the top wall of the support plate 21. A rotating hole is provided on the top wall of the support plate 21, the position of which corresponds to the position of the through hole on the feeding disc 24. The top end of the first rotating shaft 23 is positioned in the rotating hole and connected to the output end of the first motor 22, facilitating the rotation of the first rotating shaft 23. The bottom end of the first rotating shaft 23 is inserted into the through hole in the middle of the feeding disc 24. Part of the outer wall of the feeding disc 24 is connected to the wall of the through hole, which facilitates the rotation of the feeding disc 24 by the first rotating shaft 23. The feeding disc 24 has a ring-shaped... The equipment has molding cavities arranged in a pattern, with the size of the cavities increasing sequentially to facilitate the subsequent pressing of the powder into tablets of different diameters, thus expanding the equipment's applicability. A guide ring 25 is fixedly sleeved on the outer surface wall of the feeding tray 24. Part of the guide ring 25 is set in an arc-shaped groove on the inner arc wall of the support block 26 to guide the feeding tray 24 in a rotating state and maintain its stable rotation. A discharge port is provided on the top wall of the processing table 1, with the diameter of the discharge port being the same as the diameter of the largest molding cavity, facilitating subsequent material discharge.

[0022] The hydraulic cylinder 27 is fixedly installed on the top wall of the support plate 21. The top wall of the support plate 21 also has a movable opening. The output end of the hydraulic cylinder 27 passes through the movable opening and is connected to the pressure head 28 located below the support plate 21. The outer surface wall of the output end of the hydraulic cylinder 27 is provided with threads, and the top wall of the pressure head 28 is provided with a threaded groove. This allows the pressure head 28 to be fixed at the output end of the hydraulic cylinder 27 by the cooperation of the threaded groove and the thread, which makes it convenient for the staff to replace the pressure head 28 according to the size. This is beneficial for the subsequent pressing of tablets of different diameters. The annular transparent cover 3 is fixedly installed on the inner arc surface wall of the four support blocks 26 and covers the top opening of the molding cavity of the feeding tray 24, which protects the tablets and powder inside.

[0023] Furthermore, the support frame 5 is fixedly installed on the side wall of the processing table 1. The support frame 5 and the top wall of the processing table 1 are equipped with a feeding assembly 4. The feeding assembly 4 includes a feeding pipe 41, a hopper 42, a second motor 43, a second rotating shaft 44 and an auger 45. The bottom wall of the feeding pipe 41 is fixedly connected to the top wall of the processing table 1 and the top wall of the support frame 5. The support frame 5 and the processing table 1 support the feeding pipe 41. The hopper 42 is fixedly installed on the top wall of the feeding pipe 41. The bottom outlet of the hopper 42 corresponds to the top opening of the feeding pipe 41, which facilitates the introduction of the powder into the feeding pipe 41 and is beneficial for subsequent conveying.

[0024] The second motor 43 is fixedly installed on one side wall of the feeding pipe 41. Auxiliary holes and grooves are respectively provided on the outer and inner walls of one side of the feeding pipe 41. Sealed bearings are arranged in both the auxiliary holes and grooves. The two ends of the second rotating shaft 44 are respectively located in the auxiliary holes and grooves, so that the two sealed bearings are sleeved on the outer surface wall of the second rotating shaft 44 to assist in the rotation of the second rotating shaft 44 and to seal the auxiliary holes. One end of the second rotating shaft 44 is connected to the output end of the second motor 43, facilitating the second motor 43 to drive the second rotating shaft 44 to rotate within the feeding pipe 41. An auger 45 is installed inside the feeding pipe 41, sleeved on the outer surface wall of the second rotating shaft 44, facilitating automatic feeding during rotation. The inner cavity of the feeding pipe 41 is cylindrical, which is beneficial for cooperating with the auger 45 for feeding. A solenoid valve is installed at the bottom opening of the feeding pipe 41 for convenient discharge control.

[0025] Furthermore, the collection box 6 is inserted into the opening of the processing table 1 facing the wall, so that the opening of the collection box 6 is located inside the processing table 1, which facilitates the collection of tablets entering the processing table 1; the first buffer block 7 and the second buffer block 8 are both fixedly installed on the inner wall of the processing table 1, the two second buffer blocks 8 are symmetrically arranged, and the first buffer block 7 is located between the two second buffer blocks 8, which facilitates the protection and cushioning of the tablets during the feeding process, so as to prevent the tablets from falling directly into the collection box 6 and being damaged, thereby reducing the risk of product quality; the second buffer block 8, the first buffer block 7 and the collection box 6 are all made of food-grade rubber.

[0026] In this embodiment, by starting the second motor 43 to drive the second rotating shaft 44 to rotate the auger 45, the solenoid valve in the open state can guide the powder into the inlet at the top of the annular transparent cover 3 and into the corresponding molding cavity on the feeding tray 24, realizing automatic feeding of the powder. At the same time, driven by the first motor 22, the first rotating shaft 23 drives the feeding tray 24 to rotate, thereby adjusting the molding cavity carrying the powder to a position below the pressure head 28. The hydraulic cylinder 27 is started to drive the pressure head 28 to descend, so that the pressure head 28 passes through the working opening at the top of the annular transparent cover 3 and compacts the powder in the molding cavity, thereby achieving the production of tablets and completing the manufacturing process. After processing, the tablets can be moved to the discharge port by the rotation of the feeding tray 24, allowing the tablets to enter the processing table 1. The first buffer block 7 and the second buffer block 8 are used to buffer the tablets, reducing the risk of damage caused by directly moving the tablets. At the same time, during the feeding process of the feeding tray 24, due to the annular array distribution of the molding cavities, the other molding cavities of the same size can be filled with powder and compacted, so that the manufacturing, filling and discharging can be carried out simultaneously, improving production efficiency. Furthermore, since the pressure head 28 can be twisted and disassembled, it is convenient to replace the pressure head 28 according to the size of the tablets being manufactured, which is beneficial for subsequent processing of tablets of different diameters, improving the applicability and flexibility of this equipment.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
