[0011] As a preferred embodiment of this utility model, there are two fixed blocks, two sliding grooves, and two sliding blocks. The two fixed blocks are located on the left and right sides of the material hole, respectively. There are two motors and two connecting lines. The two motors are synchronously controlled by the controller through the two connecting lines.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model has a cylinder fixedly installed behind a fixed plate, an output shaft fixedly installed at the output end of the cylinder, and a connecting plate fixedly installed on the side of the output shaft away from the cylinder. The connecting plate is fixedly connected to the baffle. Since the upper part of the feed inlet is connected to the mixing tank of raw materials, when it is necessary to press the medicine, the raw materials are first stirred evenly and then transferred to the inside of the feed inlet. At this time, the cylinder is started to push the connecting plate through the output shaft, so that the connecting plate drives the baffle to move forward through the sliding action of the slider and the chute, so that the feed inlet is moved above the material hole, and the raw materials inside the feed inlet move downward with gravity. After filling the material hole, the cylinder is started to drive the output shaft to retract, so that the material hole is exposed to facilitate the pressing block to squeeze the raw materials to form medicine. After pressing is completed, the cylinder is started again to repeat the action. At this time, since the pusher plate is located in front of the feed inlet and the pusher plate is in contact with the worktable, it will first contact the pressed medicine, thereby achieving automatic unloading and preventing secondary crushing.

This utility model has a turntable fixedly installed at the output end of motor two, a connecting block fixedly installed on the outside of the turntable, a positioning shaft rotatably connected inside the connecting block, and a striking ball fixedly installed on the outside of the positioning shaft. When filling, since the raw material is in powder form, it is easy for empty layers to appear inside the material hole after falling into the material hole due to gravity. At this time, motor two is started to drive the turntable to rotate, so that the striking ball is thrown up by centrifugal force and hits the bottom of the worktable, causing the whole device to vibrate. The vibration is not too large, just enough to make the powder accumulate more solidly inside the material hole, so that the medicine will not have empty layers and the thickness of the medicine after being compressed into tablets is uneven, thus ensuring the qualification rate of the medicine.

[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] like Figures 1 to 6 As shown, this utility model provides a tableting device for solid tablets, including a workbench 1. The workbench 1 has a material hole 2 and a slide groove 3 inside. A slider 4 is slidably connected inside the slide groove 3. A connecting rod 5 is fixedly installed on the outside of the slider 4. A pusher plate 6 is fixedly installed in front of the connecting rod 5. A feed inlet 7 is fixedly installed behind the pusher plate 6. A baffle 8 is fixedly installed behind the feed inlet 7. A fixing plate 9 is fixedly installed on the top of the workbench 1. A cylinder 10 is fixedly installed behind the fixing plate 9. An output shaft 11 is fixedly installed at the output end of the cylinder 10. A connecting plate 12 is fixedly installed on the side of the output shaft 11 away from the cylinder 10. The connecting plate 12 is fixedly connected to the baffle 8.
[0024] The feed inlet 7 is connected to the mixing tank of raw materials. When the medicine needs to be pressed, the raw materials are first mixed evenly and then transferred to the inside of the feed inlet 7. At this time, the cylinder 10 is started to push the connecting plate 12 through the output shaft 11. The connecting plate 12 drives the baffle 8 to move forward through the sliding action of the slider 4 and the slide groove 3, so that the feed inlet 7 is moved above the material hole 2. The raw materials inside the feed inlet 7 move downward with gravity and fill the material hole 2. Then, the cylinder 10 is started to drive the output shaft 11 to retract, so that the material hole 2 is exposed so that the pressing block 17 can squeeze the raw materials to form medicine. After the pressing is completed, the cylinder 10 is started again to repeat the action. At this time, since the pusher plate 6 is located in front of the feed inlet 7 and the pusher plate 6 is in contact with the worktable 1, it will first contact the pressed medicine, so as to achieve automatic unloading and prevent secondary crushing.
[0025] Among them, a fixing block 13 is fixedly installed above the workbench 1. A second sliding groove 14 is opened inside the fixing block 13. A second slider 15 is slidably connected inside the second sliding groove 14. A docking plate 16 is fixedly installed on the outside of the second slider 15. A pressure block 17 is fixedly installed at the bottom of the docking plate 16.
[0026] The pressing block 17 is located directly above the material hole 2. When the inside of the material hole 2 is filled with raw material, the connecting plate 16 moves downward through the sliding connection between the sliding groove 14 and the fixed block 13, so that the pressing block 17 enters the inside of the material hole 2 to crush the raw material and achieve the effect of tableting.
[0027] Among them, a motor 18 is fixedly installed above the fixed block 13, and a lead screw 19 is fixedly installed at the output end of the motor 18. The lead screw 19 meshes with the slider 15 and is located inside the slide groove 14.
[0028] When pressing is required, first start motor 18 to drive lead screw 19 to rotate, so that lead screw 19 meshes with slider 15, thereby driving docking plate 16 to move downward, so that pressing block 17 can move downward stably.
[0029] Among them, a connecting plate 20 is fixedly installed above the fixing block 13, and a controller 21 is fixedly installed above the connecting plate 20. A connecting wire 22 is electrically connected to the outside of the controller 21, and the connecting wire 22 is fixedly connected to the motor 18.
[0030] The main function of the controller 21 is to control the start and stop of the motor 18 through the connecting line 22, so that the motor 18 can start and rotate in the opposite direction at the appropriate time, thereby increasing the tableting efficiency.
[0031] Among them, a bracket 23 is fixedly installed at the bottom of the workbench 1, a cylinder 24 is fixedly installed at the bottom of the bracket 23, a connecting shaft 25 is fixedly installed at the output end of the cylinder 24, a connecting plate 26 is fixedly installed above the connecting shaft 25, and a bottom support platform 27 is fixedly installed above the connecting plate 26. The upper end of the bottom support platform 27 is always located inside the material hole 2.
[0032] When the medicine is being compressed, the bottom support platform 27 always supports the connecting shaft 25 through the cylinder 24, keeping the bottom of the material hole 2 sealed and the position of the bottom support platform 27 fixed. After the tablet is compressed, the cylinder 24 is activated to drive the connecting shaft 25 to move upward, causing the bottom support platform 27 to push the compressed medicine upward, thereby achieving the effect of automatic unloading.
[0033] The workbench 1 has a positioning plate 28 fixedly installed at the bottom, a motor 29 fixedly installed in front of the positioning plate 28, a turntable 30 fixedly installed at the output end of the motor 29, a connecting block 31 fixedly installed on the outside of the turntable 30, a positioning shaft 32 rotatably connected inside the connecting block 31, and a ball 33 fixedly installed on the outside of the positioning shaft 32.
[0034] When filling, since the raw material is in powder form, it tends to form empty layers inside the feed hole 2 as it falls into the feed hole 2 due to gravity. At this time, the motor 29 is started to drive the turntable 30 to rotate, so that the ball 33 is thrown up by centrifugal force and hits the bottom of the worktable 1, causing the whole device to vibrate. However, the vibration is not too great, which makes the powder accumulate more compactly inside the feed hole 2. This ensures that there are no empty layers in the medicine and that the medicine is not uneven in thickness after being compressed into tablets, thus ensuring the qualified rate of the medicine.
[0035] There are two baffles 8, both located on the left and right sides of the output shaft 11, and both located behind the feed inlet 7.
[0036] The bottoms of the two baffles 8 contact the worktable 1, so that when the feed inlet 7 moves back and forth, if some powder leaks out from the gap, the powder is limited to prevent it from entering other positions and causing a situation that is difficult to clean.
[0037] There are two fixed blocks 13, two chute 14 and two sliders 15. The two fixed blocks 13 are located on the left and right sides of the material hole 2, respectively. There are two motors 18 and two connecting lines 22. The two motors 18 are synchronously controlled by the controller 21 through the two connecting lines 22.
[0038] The main function of the controller 21 is to maintain the synchronization of the start and stop of the two motors 18, thereby ensuring the balance of the docking plate 16 and preventing uneven heights.
[0039] Working principle and usage process of this utility model:
[0040] First, after the raw materials are mixed evenly, they are transported to the inside of the feed inlet 7. At this time, the cylinder 10 is started to push the connecting plate 12 through the output shaft 11, so that the connecting plate 12 drives the baffle 8 to move forward through the sliding action of the slider 4 and the slide groove 3, so that the feed inlet 7 is moved above the material hole 2, and the raw materials inside the feed inlet 7 move downward with gravity to fill the material hole 2.
[0041] The cylinder 10 is started to drive the output shaft 11 to retract, so that the material hole 2 is exposed to facilitate the pressing block 17 to squeeze the raw material to form medicine. After pressing is completed, the cylinder 10 is started again to repeat the action. At this time, since the pusher plate 6 is located in front of the feed port 7 and the pusher plate 6 is in contact with the worktable 1, it will first contact the pressed medicine, so as to achieve automatic unloading and avoid secondary crushing.
[0042] Next, start motor 18 to drive lead screw 19 to rotate, so that lead screw 19 meshes with slider 15, thereby driving docking plate 16 to move downward, so that pressure block 17 can move downward stably to achieve the pressing effect.
[0043] Finally, during the filling process, since the raw material is in powder form, it tends to form empty layers inside the feed hole 2 as it falls into the feed hole 2 due to gravity. At this time, the motor 29 is started to drive the turntable 30 to rotate, causing the ball 33 to be thrown up by centrifugal force and hit the bottom of the worktable 1, which causes the whole device to vibrate. However, the vibration is not too great, which makes the powder accumulate more compactly inside the feed hole 2. This ensures that there are no empty layers in the medicine and that the medicine is not uneven in thickness after being compressed into tablets, thus ensuring the qualified rate of the medicine.
