[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: A tablet compressor with an automatic ejection structure includes a base 1, a vertical plate 2 fixedly connected to one side of the top of the base 1, and a cover plate 3 fixedly connected to the middle of the top of the base 1; a gear 4 is rotatably connected between the top of the base 1 and the cover plate 3, and the gear 4 is driven by a motor; a guide groove 5 is provided on the top of the base 1, and a pad block 6 is fixedly connected to the side of the guide groove 5 away from the vertical plate 2; equidistantly distributed moving blocks 7 are installed on the outside of the gear 4, and the moving blocks 7 are rotatably connected end to end to form a chain structure; a discharge chute 21 is fixedly connected to one side of the top of the cover plate 3, and the bottom of the discharge chute 21 and the top of the moving blocks 7 are in contact with each other. The material discharge chute 21 and the top of the moving block 7 are designed with an arc-shaped structure. The moving block 7 has a mounting hole 8 in the middle, and a mounting sleeve 9 is slidably connected inside the mounting hole 8. A top block 10 is slidably connected inside the mounting sleeve 9. The bottom of the top block 10 extends downward through the bottom of the moving block 7 and the bottom of the mounting hole 8. The lower end of the top block 10 is slidably connected inside the guide groove 5. The moving block 7 has a locking groove 11 on the side near the gear 4. The locking groove 11 is locked to the outside of the gear 4. Two hinge blocks 12 are symmetrically installed on the side of the moving block 7 near the gear 4. The moving block 7 is connected end to end through the mutual connection of the hinge blocks 12.

[0026] After the equipment starts operating, powder is first filled into the mounting sleeve 9 by the feeding hopper 20. The top block 10 is installed inside the mounting sleeve 9, forming a closed molding groove with its inner wall to accommodate the powder. The gear 4 rotates under the drive of the motor, driving the moving block 7 to move along a predetermined track. During the movement of the moving block 7, the lower end of the top block 10 at its bottom is slidably connected to the guide groove 5 to ensure stable movement. When the moving block 7 passes the bottom of the feeding hopper 20, the powder inside the feeding hopper automatically falls into the molding groove, completing the material filling.

[0027] As the moving block 7 continues to move forward, the forming groove carrying the powder will enter below the pressure block 18. At this time, the pressure block 18 will apply high pressure downward to compress the powder into tablets. During the pressing process, the top block 10 and the pressure block 18 work together to uniformly compress the powder, ensuring that the density and hardness of the tablets meet the requirements.

[0028] After pressing, the moving block 7 continues to move forward, carrying the formed tablets toward the discharge trough 21. When the moving block 7 moves to the top of the pad block 6, the pad block 6 contacts the top block 10, causing the top block 10 to move upward along the inside of the mounting sleeve 9, thereby ejecting the tablets. The tablets are lifted to the top of the moving block 7. When the moving block moves to the vicinity of the discharge trough 21, the tablets are intercepted by the edge of the discharge trough and eventually fall into the discharge trough, completing the collection.

[0029] The mounting sleeve 9 can be removed from the inside of the mounting hole 8 to separate it from the top block 10, making it easier to clean and replace molds of different specifications, thus adapting to the production of tablets of different sizes.

[0030] Example 2: Based on Example 1, the following structure is also disclosed: A mounting plate 13 is fixedly connected to one side of the top of the upright plate 2, and a self-tightening screw 15 is rotatably connected inside the mounting plate 13. The upright plate 2 has two mounting grooves 14, which are symmetrically distributed on both sides of the mounting grooves 14. An adjusting block 16 is slidably connected inside the mounting groove 14, and the middle of the adjusting block 16 is threadedly connected to the outside of the self-tightening screw 15. Two symmetrically distributed rotating blocks 17 are rotatably connected to the bottom of the adjusting block 16, and annularly distributed pressure blocks 18 are fixedly connected to the outside of the rotating blocks 17. A mounting hoop 19 is fixedly connected to the side of the upright plate 2 away from the mounting plate 13, and a feeding hopper 20 is fixedly connected inside the mounting hoop 19. The lower end of the feeding hopper 20 and the top of the mounting sleeve 9 are aligned with each other.

[0031] When the moving block 7 moves below the pressure block 18, the pressure block 18 moves downward and enters the mounting sleeve 9, applying pressure to the powder inside to form tablets. After completing one pressing cycle, the pressure block 18 moves away as the rotating block 17 rotates. At this time, a new pressure block 18 enters the working position, aligns with the next mounting sleeve 9, and continues to perform the pressing task, realizing continuous operation and improving production efficiency.

[0032] Users can manually or automatically control the rotation direction of the self-tightening screw 15, causing it to move the adjusting block 16 up and down. The movement of the adjusting block 16 will directly affect the position of the rotating block 17 and the pressure block 18 on it, thereby changing the pressure applied to the powder.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
