[0002] A pharmaceutical tablet compressor is a specialized piece of equipment used in the pharmaceutical industry to compress granular or powdered drug raw materials into tablets with a specific shape, weight, and hardness. It uses mechanical pressure to tightly bind drug particles, forming tablets that meet quality standards, and is one of the core pieces of equipment in the tablet manufacturing process.

[0003] In Chinese patent CN218701581U, a pharmaceutical tablet press is mentioned. The specification discloses that a cylinder drives a pressure plate and a pressure head to move downward and extend into the forming hole to press the tablet. A drive assembly can move the mold in conjunction with the movement of the pressure plate, thereby moving the fixed push rod relative to the forming hole and pushing out the tablet, thus achieving the function of convenient tablet removal.

[0004] In the aforementioned application, the compressed tablets are pushed out of the hole through the meshing transmission of gears and racks. However, after the tablets are pushed out of the hole, the staff still needs to collect the pushed-out tablets, which is a rather troublesome operation. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical tablet press to solve the problem that existing pharmaceutical tablet presses are not convenient for quickly removing the pressed tablets.

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1-4 As shown, this utility model provides a pharmaceutical tablet compressor, including a worktable 1. A support frame 2 is fixedly connected to the end face of the worktable 1. An electric push rod 3 is fixedly installed on the surface of the support frame 2. A pressure plate 4 is fixedly connected to the output end of the electric push rod 3. Multiple pressure columns 5 are fixedly connected to the bottom surface of the pressure plate 4. Multiple discharge holes 6 are opened on the end face of the worktable 1. Support columns 7 are slidably inserted into the inner walls of the multiple discharge holes 6. A support plate 8 is fixedly connected to the bottom end of the multiple support columns 7. A fixed seat 9 is fixedly installed on the side wall of the worktable 1. A servo motor 10 (any model that meets the requirements of this utility model can be used, and no specific limitation is made here) is fixedly connected to the surface of the fixed seat 9. A support rod 11 is fixedly connected to the output end of the servo motor 10.

[0024] In this embodiment, the servo motor 10 drives the support rod 11 to rotate by 90 degrees each time it starts, thereby achieving the effect of adjusting the height of the support plate 8.

[0025] In an optional embodiment: the support rod 11 is located below the support plate 8, the support plate 8 has a circular arc shape in cross-section, and the support rod 11 has an elliptical shape in cross-section.

[0026] It should be noted that when the support rod 11 rotates, it will press against the support plate 8. Since the cross-sectional shape of the support rod 11 is elliptical, the height of the support plate 8 can be adjusted.

[0027] In an optional embodiment: a first spring 12 is fitted onto the arc surface of one of the support columns 7, and the two ends of the first spring 12 are fixedly connected to the worktable 1 and the support plate 8, respectively.

[0028] It should be noted that the first spring 12 serves to stabilize the position of the support column 7 and also facilitates the rebound of the support column 7.

[0029] In an optional embodiment: the end face of the workbench 1 is provided with a feeding frame 13, the bottom surface of the feeding frame 13 is provided with a plurality of drainage holes 14 that are adapted to the feeding holes 6, the surface of the feeding frame 13 is fixedly connected with a fixing block 15, the surface of the pressure plate 4 is fixedly connected with two support rods 19, the end of the two support rods 19 away from the pressure plate 4 is fixedly connected with a rectangular block 20, the surface of the feeding frame 13 is fixedly connected with two round rods 16, the arc surfaces of the two round rods 16 are slidably fitted with fixing sleeves 17, and the two fixing sleeves 17 are fixedly connected to the end face of the workbench 1.

[0030] It should be noted that when the fixed block 15 is squeezed and moved, it will cause the round rod 16 to slide along the inside of the fixed sleeve 17.

[0031] In an optional embodiment: a second spring 18 is sleeved on the arc surface of the round rod 16, and the two ends of the second spring 18 are fixedly connected to the fixed sleeve 17 and the round rod 16 respectively.

[0032] It should be noted that the second spring 18 facilitates the rebound of the feeding frame 13. Through the rebound of the feeding frame 13, the edge of the feeding frame 13 will squeeze the tablets pushed out by the support column 7 and push the tablets away, thus minimizing the need for staff to manually pick up the tablets.

[0033] In an optional embodiment: the cross-sectional shape of the fixing block 15 is a right triangle, and the rectangular block 20 fits against the inclined surface of the fixing block 15.

[0034] It should be noted that the fixed block 15 can slide after being squeezed by the rectangular block 20.

[0035] The working principle of this utility model is as follows: During use, medicine powder is placed in the feeding frame 13. The medicine powder flows through the leakage hole 14 into the feeding hole 6 and contacts the support column 7. After multiple feeding holes 6 are filled, the electric push rod 3 is activated, driving the pressure plate 4 and pressure column 5 downwards. At this time, the rectangular block 20 moves downwards and squeezes the fixed block 15. Since the side of the fixed block 15 being squeezed is inclined, the fixed block 15 will drive the round rod 16 to slide along the inside of the fixed sleeve 17. The second spring 18 is in a stretched state, and the rectangular block 20 will slide along the inclined surface of the fixed block 15. Finally, the leakage hole 14 will move away from the feeding hole 6, and the pressure column 5 will enter the feeding hole 6 to squeeze the medicine powder, forming the medicine powder. After pressing, the electric push rod 3 is retracted and the servo motor 10 is activated. The output of the servo motor 10 drives the support rod 11 to rotate 90 degrees. The rotation of the support rod 11 compresses the support plate 8, which in turn drives the support column 7 to move upward. The support column 7 then pushes the compressed tablets out of the discharge hole 6. At the same time, as the electric push rod 3 retracts, the second spring 18 rebounds, forcing the discharge frame 13 back to its original position, that is, the position of the drain hole 14 coincides with the discharge hole 6. The edge of the discharge frame 13 will squeeze the tablets pushed out by the support column 7 and push them away. The staff can place a collection box next to it in advance to collect the tablets. Then, the servo motor 10 is restarted, and the output of the servo motor 10 rotates 90 degrees. At this time, the support plate 8 will drive the support column 7 to move downward, and the medicine powder in the discharge frame 13 will continue to flow from the drain hole 14 into the discharge hole 6.
