[0001] This invention relates to the field of metformin hydrochloride sustained-release tablets, and more specifically to a metformin tablet compression machine. Background Technology

[0002] Metformin hydrochloride extended-release tablets mainly lower blood sugar by reducing hepatic glucose output and improving peripheral insulin resistance. They are suitable for type 2 diabetes patients whose blood sugar cannot be well controlled by diet and exercise alone.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0030] According to one aspect of the invention, such as Figure 1-8 As shown, a metformin tablet compression machine is provided, including an operating table 1, a lower mold mechanism 2 slidably connected to the upper surface of the operating table 1, an upper mold mechanism 3 fixedly installed on the upper surface of the operating table 1 to the left of the lower mold mechanism 2, a feeding mechanism 4 fixedly installed on the upper surface of the operating table 1 to the left of the upper mold mechanism 3, and an injection mechanism 5 fixedly installed on the upper surface of the operating table 1 to the right of the lower mold mechanism 2.

[0031] When using this device, the lower mold mechanism 2 is moved to the lower part of the injection mechanism 5 by the control panel 1, and the material to be pressed is injected by the injection mechanism 5. Then, the lower mold mechanism 2 is moved to the lower part of the upper mold mechanism 3 by the control panel 1, and the upper mold mechanism 3 presses and shapes the material. Finally, the material is unloaded by the unloading mechanism 4.

[0032] In this embodiment, the operating table 1 includes a platform plate 101. A horizontal groove 6 is formed on the upper surface of the platform plate 101. A horizontal groove 7 is formed on the upper surface of the platform plate 101 in front of and behind the horizontal groove 6. A connecting groove 8 is integrally formed between the horizontal groove 6 and the horizontal groove 7. A motor 102 is fixedly installed on the right side of the platform plate 101. A screw 103 is fixedly connected to the left end of the output shaft of the motor 102 inside the horizontal groove 6. Support legs 104 are symmetrically fixedly connected to the lower surface of the platform plate 101. Universal wheels 105 are symmetrically fixedly connected to the bottom of the support legs 104.

[0033] The screw 103 inside the horizontal groove 6 can rotate under the drive of the motor 102. In conjunction with the limiting strip 203 of the horizontal groove 7, and the connection of the connecting groove 8 and the connecting piece 202, the screw block 201 can slide along the screw 103. The support leg 104 supports the device at a certain height for easy operation, and the caster wheel 105 facilitates the overall movement of the device.

[0034] In this embodiment, the lower mold mechanism 2 includes a screw block 201, which is threadedly connected to the screw rod 103. The front and rear surfaces of the screw block 201 are fixedly connected to connecting pieces 202 inside the connecting groove 8. The two connecting pieces 202, located away from the screw block 201, are fixedly connected to limit strips 203 inside the two horizontal grooves 7. A lower template 204 is fixedly connected above the opposite sides of the two limit strips 203. The upper surface of the lower template 204 is provided with multiple forming holes 9. The inner sidewall of the forming hole 9 is integrally formed with a retaining ring 10 and a retaining ring 11 from top to bottom. A forming baffle 12 is provided above the retaining ring 10. Multiple springs 13 are fixedly connected between the forming baffle 12 and the retaining ring 11.

[0035] Under the limitation of the connecting piece 202 and the limiting strip 203, the screw block 201 can slide with the screw 103, thereby driving the lower template 204 to move. The forming hole 9 and the forming baffle 12 are used for injecting liquid medicine to form. The forming baffle 12 is restricted from descending by the set baffle ring 10. The forming baffle 12 is connected to the baffle ring 11 through the spring 13, so that the forming baffle 12 can slide upward along the forming hole 9, thereby facilitating the pushing of the formed tablet out of the forming hole 9.

[0036] In this embodiment, lifting grooves 14 are provided on opposite sides of the two limiting bars 203. Lifting blocks 15 are slidably connected to the inner side of the lifting grooves 14. Spring 16 is fixedly connected between the lifting blocks 15 and the lifting grooves 14. A lifting plate 17 is fixedly connected between the two lifting blocks 15. Threshing rods 18 are fixedly connected to the upper surface of the lifting plate 17 inside the multiple forming holes 9. Threshing plates 19 are fixedly connected to the top of the threshing rods 18. The upper surface of the threshing plates 19 is in contact with the lower surface of the forming baffle 12.

[0037] By utilizing the lifting groove 14, lifting block 15 and spring 16, under normal conditions, the lower surface of the lifting plate 17 is in contact with the top of the screw block 201 under the pull of spring 16. When the lifting plate 17 moves upward, it will drive the threshing plate 19 on the threshing rod 18 to rise, thereby pushing the forming baffle 12 to rise.

[0038] In this embodiment, an auxiliary plate 20 is symmetrically fixedly connected to the upper surface of the platform plate 101 on the left side of the lifting plate 17. A slope 21 is integrally formed on the right side of the auxiliary plate 20, and a plurality of shaking grooves 22 are integrally formed on the outer side wall of the slope 21.

[0039] When the lifting plate 17 moves to the left, it comes into contact with the slope 21 on the auxiliary plate 20 and is pushed up by the pressure. Under the influence of the shaking groove 22, the lifting plate 17 will shake as it rises, so that when the threshing tablet 19 pushes the forming baffle 12, it will shake and push upward, which makes it easier for the tablet to separate from the forming baffle 12.

[0040] In this embodiment, the upper mold mechanism 3 includes a U-shaped frame 301. A hydraulic rod 302 is fixedly connected to the upper surface of the U-shaped frame 301. An upper template 303 is fixedly connected to the bottom end of the hydraulic rod 302 inside the U-shaped frame 301. An airbag ring 304 is fixedly connected to the lower surface of the upper template 303. An air cavity 305 is opened inside the upper template 303. Multiple telescopic holes 306 are integrally formed on the lower surface of the air cavity 305. Two ventilation grooves 307 are integrally formed between the air cavity 305 and the airbag ring 304. A piston plate 308 is slidably connected to the inner side of the air cavity 305. A pressing column 309 is fixedly connected to the lower surface of the piston plate 308 inside the multiple telescopic holes 306.

[0041] The hydraulic rod 302 on the U-shaped frame 301 moves downward through the output end, causing the upper template 303 to descend. When the airbag ring 304 contacts the lower template 204, it is squeezed and the internal gas is introduced into the air chamber 305 through the air exchange groove 307, thereby causing the piston plate 308 to descend. Then, the pressing column 309 in the telescopic hole 306 will slide down, thereby pressing and shaping the liquid medicine in the forming hole 9.

[0042] In this embodiment, the feeding mechanism 4 includes a fixed plate 401. Two transmission rollers 402 are symmetrically rotatably connected between the opposite sides of the two fixed plates 401 via a rotating shaft. Two transmission belts 403 are connected to the outer side walls of the two transmission rollers 402. A scraper 404 is connected to the outer side walls of the two transmission belts 403. A motor 405 is fixedly connected to the front surface of the fixed plate 401 located in front of the feeding mechanism 4. The rear end of the output shaft of the motor 405 is fixedly connected to the front end of the central shaft of the transmission roller 402 located to the right of the fixed plate 401.

[0043] Start motor 405, which causes the transmission belt 403 to drive the scraper 404 to move, thereby allowing the shaped tablets to be fed out.

[0044] In this embodiment, the injection mechanism 5 includes a U-shaped frame 501. A mounting block 502 is fixedly connected to the lower surface of the U-shaped frame 501, and a material box 503 is fixedly connected to the upper surface of the mounting block 502. The top of the material box 503 extends through to the top of the U-shaped frame 501. Multiple injection tubes 504 are fixedly connected to the lower surface of the material box 503, and the bottom ends of the injection tubes 504 extend through to the bottom of the mounting block 502. A movable plate 505 is slidably connected to the inner side of the material box 503. Springs 506 are symmetrically fixedly connected between the movable plate 505 and the material box 503. A linkage plate 507 is provided on the right side of the material box 503. The lower surface of 07 is integrally formed with multiple trapezoidal strips 508. A connecting rod 509 is fixedly connected between the linkage plate 507 and the movable piece 505. The lower surface of the mounting block 502 is provided with a mounting groove 510. The upper surface of the inner part of the mounting groove 510 is provided with a through movable groove 511. A guide rod 512 is fixedly connected inside the mounting groove 510. A movable plate 513 is slidably connected to the outer wall of the guide rod 512. A trapezoidal strip 514 is integrally formed on the upper surface of the movable plate 513 located inside the movable groove 511. A spring 515 is symmetrically fixedly connected between the movable plate 513 and the mounting groove 510.

[0045] When the template 204 moves to the right and comes into contact with the moving plate 513, it pushes the moving plate 513 to move to the right. With the cooperation of trapezoidal strip 1 508 and trapezoidal strip 2 514, as well as the linkage of connecting rod 509 and linkage plate 507, the movable piece 505 can be driven to move up and down repeatedly along the material box 503.

[0046] In this embodiment, an extrusion plate 516 is slidably connected inside the material box 503 below the movable plate 505. A rotating connector 517 is fixedly connected to the upper surface of the extrusion plate 516. A connecting rod 518 is rotatably connected to the front surface of the rotating connector 517 via a rotating shaft. A groove 519 is provided on the lower surface of the movable plate 505. A crossbar 520 is fixedly connected inside the groove 519. A rotating connector 521 is slidably connected to the outer wall of the crossbar 520. The front surface of the rotating connector 521 is rotatably connected to the left end of the connecting rod 518 via a rotating shaft. A spring 522 is sleeved on the outer wall of the crossbar 520. The two ends of the spring 522 are fixedly connected to the opposite sides of the rotating connector 521 and the groove 519, respectively.

[0047] By utilizing the crossbar 520, the rotating connector 521, and the spring 522 set inside the groove 519 of the movable piece 505, along with the rotating connector 517 and the connecting rod 518, the movable piece 505 moves up and down, which drives the extrusion piece 516 to move up and down along the material box 503. This allows the material inside the material box 503 to be extruded. When the lower template 204 moves to the right, the material is gradually squeezed into the rows of forming holes 9. When the lower template 204 moves to the rightmost position and then to the left, the material is squeezed into the rows of forming holes 9 again, so that the raw material can fill the forming holes 9.

[0048] The working principle of this device is as follows: When using this device, the lower mold mechanism 2 is moved to the lower part of the injection mechanism 5 by the control panel 1, and the material to be pressed is injected by the injection mechanism 5. Then, the lower mold mechanism 2 is moved to the lower part of the upper mold mechanism 3 by the control panel 1, and the upper mold mechanism 3 presses and shapes the material. Finally, the material is unloaded by the unloading mechanism 4.
