[0001] This utility model relates to a tablet press, and more particularly to a tablet weight quantitative adjustment device for a tablet press. Background Technology

[0002] A tablet press is a device that compresses powdered materials into tablets, and it is widely used in pharmaceutical, food, and chemical industries. It mainly consists of a die, a feeding device, and a pressure mechanism. The pressure mechanism applies pressure to the material, compressing it into tablets within the die. It features high production efficiency, diverse tablet shapes, and stable quality.

[0003] However, existing tablet presses usually cannot adjust the tablet weight. One tablet press can only press tablets with a fixed weight. Tablets with different weights need to be pressed by different tablet presses, which has poor applicability and increases production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a tablet weight quantitative adjustment device for a tablet press, which can adjust the amount of raw material powder to be processed as needed, thereby achieving tablet weight adjustment, improving applicability, and saving production costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tablet weight quantitative adjustment device for a tablet press is provided, comprising a worktable, a first mounting frame fixedly connected to the lower surface of the worktable, a first hydraulic cylinder fixedly connected to the upper surface of the first mounting frame, a first moving rod fixedly connected to the upper surface of the first hydraulic cylinder, a pressing groove formed on the upper surface of the worktable, the first moving rod located inside the pressing groove, a connecting plate fixedly connected to the outer surface of the first moving rod, a first electrode plate fixedly connected to the lower surface of the connecting plate, a second electrode plate fixedly connected to the upper surface of the connecting plate, a first motor fixedly connected to the lower surface of the worktable, a double-threaded lead screw fixedly connected to the output end of the first motor, a first moving block threadedly connected to the outer surface of the double-threaded lead screw, two first moving blocks being provided, a deflection arm movably mounted on the lower surface of each first moving block, a moving plate movably mounted on the end of the deflection arm away from the first moving block, a third electrode plate fixedly connected to the upper surface of the moving plate, and a fourth electrode plate fixedly connected to the lower surface of the worktable.

[0006] Optionally, a limiting plate is fixedly connected to the lower surface of the workbench, and there are two limiting plates. A limiting groove is formed on the side wall of the first moving block, and the limiting plate is located inside the limiting groove.

[0007] Optionally, a second mounting bracket is fixedly connected to the upper surface of the workbench, a second hydraulic cylinder is fixedly connected to the lower surface of the second mounting bracket, and a second moving rod is fixedly connected to the output end of the second hydraulic cylinder, with the second moving rod located above the first moving rod.

[0008] Optionally, a second motor is fixedly connected to the upper surface of the workbench, a lead screw is fixedly connected to the output end of the second motor, a second moving block is threadedly connected to the outer surface of the lead screw, and a storage box is fixedly connected to the side wall of the second moving block.

[0009] Optionally, a top cover is fixedly connected to the upper surface of the storage box, a discharge port is fixedly connected to the upper surface of the top cover, a funnel groove is provided inside the storage box, and a discharge groove is provided on the inner surface of the funnel groove.

[0010] Optionally, the upper surface of the workbench is provided with a film dropping groove, and a placement box is fixedly connected to the lower surface of the workbench. The placement box is located below the film dropping groove, and a film storage box is provided inside the placement box. A pull ring is fixedly connected to the side wall of the film storage box, and a blocking block is fixedly connected to the side wall of the placement box. The blocking block includes an inclined block and a flat block. A stop block is fixedly connected to the side wall of the placement box, and the lower surface of the flat block is in contact with the upper surface of the stop block.

[0011] As can be seen, the lower surface of the workbench is fixedly connected with four legs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention comprises a first motor, a double-threaded lead screw, a first moving block, a deflection arm, a moving plate, a third electrode plate, a first electrode plate, a first moving rod, and a pressing groove. When the weight of the tablet needs to be adjusted, the amount of raw material powder added is changed. The first motor is controlled to rotate, causing the double-threaded lead screw to rotate, which in turn moves adjacent first moving blocks closer or further apart. To increase the weight, adjacent first moving blocks are brought closer together, causing the deflection arm to deflect, which in turn moves the moving plate and the third electrode plate downwards. This increases the maximum distance between the first moving rod and the third electrode plate when they contact each other, meaning the first moving rod's position in the pressing groove has decreased, increasing the amount of raw material powder entering the pressing groove and thus increasing the weight. To decrease the weight, adjacent first moving blocks are moved further apart. This invention allows for adjustment of the amount of raw material powder to be processed, thereby adjusting the tablet weight, improving applicability, and saving production costs.

[0026] Reference Figure 1-6The present invention will now be described. A tablet weight adjustment device for a tablet press includes a worktable 1. A first mounting bracket 2 is fixedly connected to the lower surface of the worktable 1. A first hydraulic cylinder 3 is fixedly connected to the upper surface of the first mounting bracket 2. A first moving rod 4 is fixedly connected to the upper surface of the first hydraulic cylinder 3. A pressing groove 5 is formed on the upper surface of the worktable 1. The first moving rod 4 is located inside the pressing groove 5. A connecting plate 6 is fixedly connected to the outer surface of the first moving rod 4. A first electrode plate 7 is fixedly connected to the lower surface of the connecting plate 6. A second electrode plate 8 is fixedly connected to the upper surface of the connecting plate 6. A first motor 9 is fixedly connected to the lower surface of the worktable 1. A double-threaded screw 10 is fixedly connected to the output end of the first motor 9. A first moving block 11 is threadedly connected to the outer surface of the double-threaded screw 10. There are two first moving blocks 11. A deflection arm 12 is movably mounted on the lower surface of the first moving block 11. The deflection arm 12 is located away from the first moving block 11. A movable plate 13 is installed at the end, and a third electrode plate 14 is fixedly connected to the upper surface of the movable plate 13. When it is necessary to adjust the weight of the tablet, that is, to change the amount of raw material powder added, the first motor 9 is controlled to work, driving the double threaded screw 10 to rotate, thereby causing the adjacent first movable blocks 11 to move closer or further apart. If it is necessary to increase the weight of the tablet, the adjacent first movable blocks 11 are controlled to move closer together, causing the deflection arm 12 to deflect, thereby causing the movable plate 13 and the third electrode plate 14 to move downward. At this time, the first movable rod 4 moves downward until the maximum distance when the third electrode plate 14 contacts the first electrode plate 7 increases, that is, the position of the first movable rod 4 in the pressing groove 5 moves downward, and the amount of raw material powder entering the pressing groove 5 increases, thereby increasing the weight of the tablet. If it is necessary to decrease the weight of the tablet, the adjacent first movable blocks 11 are controlled to move further apart. A fourth electrode plate 35 is fixedly connected to the lower surface of the worktable 1.

[0027] The tablet weight quantitative adjustment device for tablet presses provided by this utility model, compared with the prior art, can adjust the amount of raw material powder to be processed as needed, thereby realizing the adjustment of tablet weight, improving applicability and saving production costs.

[0028] Please refer to another embodiment of this utility model as well. Figures 1 to 6Two limit plates 15 are fixedly connected to the lower surface of the worktable 1. A limit groove 16 is formed on the side wall of the first moving block 11. The limit plates 15 and the limit groove 16 cooperate to restrict the movement of the first moving block 11. The limit plates 15 are located inside the limit groove 16. A second mounting bracket 17 is fixedly connected to the upper surface of the worktable 1. The second mounting bracket 17 is for mounting a second hydraulic cylinder 18. The lower surface of the second mounting bracket 17 is fixedly connected to the second hydraulic cylinder 18. A second moving rod 19 is fixedly connected to the output end of the second hydraulic cylinder 18. The second moving rod 19 is located above the first moving rod 4. A second motor 20 is fixedly connected to the upper surface of the worktable 1. A wire is fixedly connected to the output end of the second motor 20. The outer surface of the lead screw 21 is threaded with a second moving block 22. A storage box 23 is fixedly connected to the side wall of the second moving block 22. The storage box 23 is used to hold the raw material powder to be processed. A top cover 24 is fixedly connected to the upper surface of the storage box 23, and a discharge port 25 is fixedly connected to the upper surface of the top cover 24. The discharge port 25 is used to add the raw material powder to be processed into the storage box 23. A funnel groove 26 is provided inside the storage box 23. Both the funnel groove 26 and the discharge groove 27 are designed to allow the powder to enter the pressing groove 5 more effectively. The inner surface of the funnel groove 26 has a discharge groove 27. Initially, the first moving rod 4 is stationary, and the second hydraulic cylinder 18 operates, driving the second moving rod 19 upwards, thereby controlling the second motor 20 to operate and drive the lead screw 21. 1. Rotation causes the second moving block 22 and the storage box 23 to move to the right, aligning the discharge chute 27 with the pressing chute 5. The raw material powder to be processed falls into the pressing chute 5 along the discharge chute 27. Then, the second motor 20 operates, causing the storage box 23 to move to the left and reset. The second hydraulic cylinder 18 operates, causing the second moving rod 19 to move down and compress the raw material powder into tablets. Then, the second hydraulic cylinder 18 operates, causing the second moving rod 19 to return to its original position. At the same time, the first hydraulic cylinder 3 operates, causing the first moving rod 4 to move up until the second electrode plate 8 contacts the fourth electrode plate 35 and stops moving. At this time, the tablet is just removed from the pressing chute 5. Then, the second motor 20 operates, continuing to move the storage box 23 to the right. At this time, the storage box 23 pushes the tablet to the right and it falls into the tablet dropping chute 2. In step 8, the first moving rod 4 then moves down again until the first electrode plate 7 contacts the third electrode plate 14 and stops moving. The raw material powder continues to fall into the pressing groove 5 along the discharge chute 27. Repeating the previous operation can realize the automated production of tablets. The upper surface of the workbench 1 is provided with a tablet dropping groove 28, and the lower surface of the workbench 1 is fixedly connected to a placement box 29.
