DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] like Figures 1 to 3 As shown, a tablet pressing device comprises: a turning plate 1, a material magazine 2, a pressing plate 3 and a material receiving box 4.

[0018] A plurality of forming holes 11 are vertically opened on the top surface of the flip plate 1 , and a horizontal rotating shaft 12 is provided on one side of the flip plate 1 . The flip plate 1 is rotatably arranged around the rotating shaft 12 , and the rotating shaft 12 is driven by a motor.

[0019] The magazine 2 is arranged on the top surface of the flip plate 1, and the bottom surface of the magazine 2 is in sliding contact with the top surface of the flip plate 1. A discharge hole 21 is opened at the bottom of the magazine 2 for feeding materials into the forming hole 11. The top surface of the flip plate 1 at one end corresponding to the sliding direction of the magazine 2 has a flat portion 13. When the magazine 2 moves to the flat portion 13, the discharge hole 21 is in a closed state. The magazine 2 is provided with a detachable cover to facilitate the addition of powder and prevent the powder from spilling during the rotation of the flip plate 1.

[0020] The pressing plate 3 is arranged on one side of the rotating shaft 12, and a pressing head corresponding to the forming hole 11 is provided at the bottom of the pressing plate 3; when the flip plate 1 rotates to a predetermined position below the pressing plate 3, the pressing head on the bottom surface of the pressing plate 3 is coaxial with the corresponding forming hole 11, and the pressing plate 3 is moved in a direction perpendicular to the bottom surface. Specifically, the pressing plate 3 is moved by a cylinder, a hydraulic cylinder or a linear motor.

[0021] The receiving box 4 is arranged on the other side of the rotating shaft 12 , and the opening of the receiving box 4 faces upward. When the flip plate 1 rotates to a predetermined position above the receiving box 4 , the forming holes 11 on the top surface of the flip plate 1 are all located within the opening range of the receiving box 4 .

[0022] The tablet pressing process is as follows: the flip plate 1 is rotated to the bottom of the pressing plate 3, so that the top surface of the flip plate 1 faces upward, and the powder is added to the magazine 2. The magazine 2 is slid on the top surface of the flip plate 1, and the powder inside it will be discharged from the discharge hole 21, and in the process of the movement of the magazine 2, the powder is pushed into the forming hole 11. The magazine 2 can be pushed manually, or a telescopic device can be set on the flip plate 1 to push the magazine 2; through the structure of sliding contact between the bottom of the magazine 2 and the top surface of the flip plate 1, the powder can always be within the range of the discharge hole 21 to prevent the powder from scattering to the forming hole 11 and places outside the magazine 2. At the same time, the structure of sliding contact between the bottom of the magazine 2 and the top surface of the flip plate 1 is used to scrape the powder inside the forming hole 11 flat, so that the volume of the powder in all the forming holes 11 is the same as the volume of the corresponding forming hole 11, so as to accurately control the amount of powder in each tablet. The magazine 2 can slide back and forth on the flip plate 1 once or multiple times, and finally the magazine 2 is moved above the flattening part 13. The pressing plate 3 is moved downward so that the pressure head at the bottom of the pressing plate 3 is pressed into the forming hole 11, thereby pressing the powder in the forming hole 11 into shape, and then the pressing plate 3 is raised. The flip plate 1 is rotated to the top of the material receiving box 4, and the tablets in the forming hole 11 are poured downward into the material receiving box 4 by patting or utilizing the impact force between the flip plate 1 and the material receiving box 4 when the flip plate 1 rotates. The above scheme can quickly feed the powder into multiple forming holes 11, which can effectively improve the tableting efficiency. The tablets pressed in the forming hole 11 are automatically discharged by patting or impacting, which not only achieves the purpose of automatically collecting tablets, but also does not need to set a push rod to push the tablets, making the overall structure of the flip plate 1 simpler.

[0023] Preferably, Figures 1 to 3As shown, the top surface of the flip plate 1 is surrounded by side panels, the magazine 2 is located inside the side panels, and both ends of the magazine 2 are provided with guide rods 22 extending outward, and the side of the side panels corresponding to the guide rods 22 are provided with strip holes 14 consistent with the sliding direction of the magazine 2, and the guide rods 22 pass through the corresponding strip holes 14 and protrude from the outside of the side panels, and the sliding direction of the magazine 2 is perpendicular to the rotating shaft 12; the lower side of the pressure plate 3 is provided with linear mechanisms 5 on both sides of the corresponding flip plate 1, and the linear mechanisms 5 are provided with sliders 51, and their sliding directions are parallel to the pressure plate 3. The bottom surface is perpendicular to the rotating shaft 12, and the top surface of the slider 51 is provided with a card slot 511. When the flip plate 1 rotates to a predetermined position below the pressure plate 3, the guide rod 22 is inserted into the card slot 511 on the corresponding side. In this way, the linear mechanism 5 can be used to drive the material magazine 2 to move back and forth along the direction perpendicular to the rotating shaft 12 through the slider 51 and the guide rod 22, thereby achieving the purpose of adding medicine to the forming hole 11; when the flip plate 1 rotates toward the side of the material receiving box 4, the guide rod 22 will automatically separate from the card slot 511 upward; the linear mechanism 5 is a rodless cylinder or a linear motor.

[0024] Preferably, Figure 3 As shown, the flattened portion 13 is located at one end of the flip plate 1 close to the rotating shaft 12, and when the magazine 2 is located above the flattened portion 13, the magazine 2 moves to the limit position corresponding to the end of the flip plate 1, so that the magazine 2 can be prevented from moving toward the other end of the flip plate 1 during the rotation of the flip plate 1, so as to facilitate the guide rod 22 to automatically connect with the slot 511 again; at the same time, the weight of the magazine 2 is made closer to the rotating shaft 12 to reduce the torque required for the rotation of the rotating shaft 12.

[0025] Preferably, Figure 1 , Figure 2 As shown, the tablet pressing device also includes a base 6, a support plate is provided in the middle of the top surface of which, for mounting the rotating shaft 12, the receiving box 4 is arranged on the base 6, and a cushion block 61 is provided on the base 6 corresponding to the bottom of the pressing plate 3. When the flip plate 1 rotates to the bottom of the pressing plate 3 to press the tablets, the bottom surface of the flip plate 1 is supported on the top surface of the cushion block 61. Furthermore, the linear mechanism 5 can be arranged on the base 6.

[0026] Preferably, Figure 1 As shown, a worm wheel is coaxially provided at one end of the rotating shaft 12, and the worm wheel is meshed with a worm, and the worm is coaxially provided on the main shaft of a driving motor. The driving motor is used to drive the rotating shaft 12 to rotate through a worm and worm wheel transmission, thereby controlling the flipping of the flip plate 1, which can make the flipping of the flip plate 1 more stable and prevent the flip plate 1 from slipping around the rotating shaft 12.

[0027] Preferably, Figure 1 , Figure 2As shown, the tablet pressing device also includes a support column 7, which is arranged on the outside of the pressing plate 3, and the support column 7 is perpendicular to the pressing plate 3. A cantilever 71 is provided on the top of the support column 7. One end of the cantilever 71 is rotatably connected to the support column 7, and a pressure device 72 is provided on the top of the other end. The lower end of the pressure rod of the pressure device 72 is connected to the top surface of the pressing plate 3. The pressure device 72 is used to drive the pressing plate 3 to move. The pressure device 72 is a hydraulic cylinder or a cylinder. This solution can move the pressing plate 3 away from the top of the flip plate 1 through the cantilever 71 to reduce the distance between the pressing plate 3 and the flip plate 1, and at the same time, meet the flip plate 1's demand for rotation space to avoid the pressing plate 3 affecting the rotation of the flip plate 1.

[0028] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
