[0002] Metformin extended-release tablets generally refer to metformin hydrochloride extended-release tablets, which are mainly used to lower blood sugar, reduce the production of glucose in the liver and the absorption of glucose in the intestine, and increase peripheral glucose uptake and utilization, thereby improving insulin sensitivity and lowering basal and postprandial blood sugar.

[0003] During the production process of metformin sustained-release tablets, the raw materials need to be mixed and dried into solids, the solid drugs are then crushed to obtain raw powder, and finally the powder is pressed into tablets for storage and use. Most of the existing tablet pressing equipment used in tablet pressing operation uses a single tablet pressing mold, that is, the equipment moves downward once during operation to press out a tablet of medicine. This type of tablet pressing equipment has a low finished product output rate per unit time and low tablet pressing efficiency.

[0004] Therefore, we made improvements to this and proposed a metformin sustained-release tablet production device. Utility Model Content

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figures 1 to 3 As shown, the utility model is a metformin sustained-release tablet production device, including a frame 1, a front side of the frame 1 is provided with a slot, and one side of the frame 1 is also provided with an existing control switch for controlling the operation of the electrical components in the present application, such as controlling the operation of cylinder 1 13, cylinder 2 15 and motor 3.

[0022] The top of the frame 1 is provided with a mounting cavity 2, and a mounting plate is detachably mounted on the front of the mounting cavity 2. A mounting shaft 6 is rotatably mounted in the mounting cavity 2, and a rotating shaft 4 is rotatably mounted in the mounting cavity 2. A gear 1 5 is fixedly sleeved on the rotating shaft 4, and a gear 2 7 is fixedly sleeved on the mounting shaft 6, and the gear 1 5 is meshed with the gear 2 7 for transmission. A motor 3 is mounted on the top surface of the mounting cavity 2, and the output end of the motor 3 is fixedly connected to the top of the rotating shaft 4. When the motor 3 is working, it will drive the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 will drive the gear 1 5 thereon to rotate, and the gear 1 5 will mesh with the gear 2 7 to drive the gear 2 7 to rotate, thereby driving the mounting shaft 6 fixedly connected to the gear 2 7 to rotate.

[0023] The bottom end of the mounting shaft 6 is fixedly connected with a turntable 1 9, the bottom of the turntable 1 9 is rotatably provided with a turntable 2 10, the bottom of the turntable 2 10 is rotatably provided with a turntable 3 11, and the turntable 1 9 and the turntable 3 11 are fixedly connected; when the mounting shaft 6 rotates, the turntable 1 9 will rotate together, the turntable 1 9 can drive the turntable 3 11 to rotate, and the turntable 2 10 remains stationary.

[0024] A plurality of molds 14 are evenly and fixedly arranged along the circumference of the turntable 10, a hopper 8 is installed on the top surface of the turntable 19, a discharge port 12 is connected to the bottom end of the hopper 8, and the discharge port 12 extends to the bottom of the turntable 19; a quantitative electric valve (not shown in the figure) is arranged in the hopper 8, when the discharge port 12 is aligned with the mold 14, the quantitative electric valve controlled by the control switch will open, and the powdered raw material in the hopper 8 will be injected into the mold 14 through the discharge port 12.

[0025] The bottom surface of the turntable 1 9 is also provided with a cylinder 13, and the telescopic end of the cylinder 13 is fixedly connected with a pressing plate 22; the top surface of the turntable 3 11 is installed with a cylinder 2 15, and the telescopic end of the cylinder 2 15 is fixedly connected with a baffle 16; the cylinder 13 is arranged on one side of the turntable 1 9, and when the turntable 1 9 rotates, the raw material in the hopper 8 is first injected into the mold 14. Before the injection, the cylinder 2 15 corresponding to the hopper 8 drives the baffle 16 to cover the bottom end of the mold 14 to prevent the powder from falling out. And it remains in a shielded state during the injection process. It should be noted that the baffle 16 on the cylinder 2 15 located at the bottom of the discharge port 12 is an arc-shaped structure and can simultaneously shield the bottom ends of the three molds 14. Therefore, after the raw materials are injected and the cylinder 13 drives the pressing plate 22 downward to compact the powder, the baffle 16 is still located at the bottom end of the mold 14. When it then moves to the bottom end of another mold 14, the cylinder 13 pushes the compressed tablets downward out of the mold 14.

[0026] A plurality of connecting rods 1 20 are evenly and fixedly arranged between the turntable 1 9 and the turntable 3 11 along the circumferential direction, and connecting rods 21 are fixedly arranged at the top and bottom ends of the turntable 2 10, and the connecting rods 21 are respectively rotatably connected to the turntable 1 9 and the turntable 3 11. When the turntable 1 9 rotates, the turntable 3 11 can be driven to rotate through the connecting rods 1 20, and the turntable 2 10 remains stationary during the whole process.

[0027] The mold 14 is provided with a through slot, which passes through the turntable 10; the pressing plate 22 matches the through slot, and the baffle 16 is larger than the through slot. The pressing plate 22 can enter the mold 14 to compress the powder, while the baffle 16 plays a shielding role.

[0028] The bottom end of the turntable 3 11 is rotatably provided with a support plate, which is fixedly connected to the inner wall of the frame 1; a material discharge trough 17 is provided through the turntable 3 11, which facilitates the falling of the tableted medicine. The support plate can support and connect the turntable 3 11 without affecting the rotation of the turntable 3 11.

[0029] A material receiving box 19 is slidably arranged in the frame 1 and at the bottom of the turntable 3 11. A guide plate 18 is fixedly arranged in the frame 1 and between the turntable 3 11 and the material receiving box 19, and the guide plate 18 is inclined toward the pulling direction of the material receiving box 19. After the medicine is squeezed out of the mold 14, it passes through the feeding chute 17 and enters the material receiving box 19 under the guidance of the guide plate 18 to be collected. The material receiving box 19 is made of transparent polyethylene material, which is convenient for observing the tablet pressing during tablet production.

[0030] During operation, as the turntable 9 rotates, the raw material powder in the hopper 8 will be injected into the mold 14 one by one. During the injection process into the mold 14, the cylinder 15 drives the baffle 16 to cover the bottom end of the mold 14. After the raw material is injected, the turntable 9 continues to rotate to send the raw material powder into the next mold 14. At this time, the cylinder 13 on the turntable 9 will drive the pressing plate 22 to enter the previous mold 14 injected with the raw material powder for tableting. When the tableting is completed, the cylinder 15 first drives the baffle 16 to move away, and the cylinder 13 drives the pressing plate 22 downward again to push the tabletted tablet out of the mold 14. The production device can greatly improve the production efficiency of tablets through the mutual cooperation of various components.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
