[0003] When using a tablet press, the powder needs to be manually loaded into the mold with a spoon. Since the powder is relatively fine and easily adheres to the spoon, when pouring the powder into the mold, in order to ensure that the powder can be completely poured into the mold, the mold will be knocked with the spoon to make the spoon vibrate, and the powder attached to the spoon will be shaken off into the mold. However, knocking the spoon will cause the powder to scatter outside the mold, which not only causes powder waste, but also pollutes the table. At the same time, the powder needs to be manually pressed into tablets, which is a cumbersome operation. For this reason, the present application proposes an automatic powder tablet press.

[0019] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0020] Example

[0021] See also Figures 1 to 3 The utility model provides an automatic powder tablet press, comprising a box body 1, a top plate 2, a workbench 4 for placing a mold 3 and a feeding mechanism 5 for outputting powder to the mold 3. The workbench 4 is arranged on the box body 1, and a hydraulic telescopic mechanism (not marked) is installed in the box body 1. The movable end of the hydraulic telescopic mechanism (not marked) is connected to the workbench 4. The hydraulic telescopic mechanism is a prior art and will not be described here. The top plate 2 is fixed to the box body 1 by a number of columns 17, and the columns 17 can play the role of supporting the top plate 2. A screw 18 is threadedly connected to the top plate 2, and the upper end of the screw 18 is connected to a handwheel 22. By rotating the handwheel 22, the screw 18 can be adjusted so that the screw 18 moves down and fixes the mold 3 placed on the workbench 4. A fixed protective plate 19 is connected between the box body 1 and the top plate 2 for protection. The fixed protective plate 19 is a U-shaped protective plate, and a dynamic protective plate is slidably connected to the fixed protective plate 19. Plate 21, when putting in or taking out the mold 3, the dynamic protective plate 21 can be slid open, and the unloading mechanism 5 is slidably connected to the fixed protective plate 19. After the mold 3 is placed on the workbench 4, the unloading mechanism 5 is slid so that the unloading mechanism 5 is located directly above the mold 3 to transport powder to the mold 3. The unloading mechanism 5 includes a storage hopper 6, a discharge pipe 7 and a cover plate 10. The storage hopper 6 is slidably connected to the fixed protective plate 19 through a slide rod 11. The output port of the storage hopper 6 is connected to the discharge pipe 7, and the end of the discharge pipe 7 is connected to the cover plate 10. The storage hopper 6 is filled with powder, and the powder is output to the mold 3 through the discharge pipe 7. When the powder is output, the cover plate 10 covers the open end of the mold 3 to prevent the powder from scattering outside the mold 3. A control panel 20 is installed on the box body 1, and the control panel 20 is electrically connected to the hydraulic telescopic mechanism (not marked). The hydraulic telescopic mechanism is controlled by the control panel 20 to push the workbench 4 up to press the powder in the mold 3 into tablets.

[0022] See also Figure 1 and Figure 3The unloading mechanism 5 also includes a spiral conveying blade 12, a unloading rod 13 and a handle 14. The unloading rod 13 is connected to the spiral conveying blade 12, and the spiral conveying blade 12 is rotatably arranged in the discharge pipe 7. A sealing cover 15 is provided on the storage hopper 6. The unloading rod 13 is rotatably connected to the sealing cover 15. The unloading rod 13 is connected to the handle 14. The sealing cover 15 is provided with an inlet 16. The discharge pipe 7 includes a fixed discharge pipe 8 and a movable discharge pipe 9. The fixed discharge pipe 8 is connected to the output port of the storage hopper 6, and the movable discharge pipe 9 is slidably connected to the fixed discharge pipe 8. The cover plate 10 is connected to the end of the movable discharge pipe 9. When the discharge pipe 7 is located above the mold 3, the movable discharge pipe 9 is slid to drive the cover plate 10 to move down to cover the upper open end of the mold 3. The unloading rod 13 is rotated by the handle 14, and the unloading rod 13 drives the spiral conveying blade 12 to unload.

[0023] The workbench 4 is provided with a positioning block 23, and the base of the mold 3 is provided with a positioning groove, which can be quickly positioned to facilitate the alignment of the discharge pipe 7 for unloading.

The limit rod 25 limits the sliding position of the slide rod 11, so that the storage hopper 6 moves quickly and is positioned above the mold 3. When powder needs to be stored in the storage hopper 6, the limit rod 25 can be slid upward, and the slide rod 11 can be moved to the side close to the dynamic protective plate 21, which is convenient for powder storage.

[0025] When in use, the hand wheel 22 is turned to drive the screw 18 to move upward, thereby increasing the distance between the lower end of the screw 18 and the workbench 4. A positioning block 23 is provided on the workbench 4, and a positioning groove is provided on the base of the mold 3. The mold 3 is placed on the workbench 4. The positioning block 23 cooperates with the positioning groove to quickly position the mold 3. The storage hopper 6 is slid, and the limit rod 25 limits the sliding distance of the slide rod 11. When the discharge pipe 7 is located directly above the mold 3, the discharge pipe 9 is slid to move the cover plate 10 downward to cover the upper open end of the mold 3, thereby sealing the opening of the mold 3. At the mouth end, the handle 14 drives the discharge rod 13 and the spiral conveying blade 12 to rotate, and the powder is transported to the mold 3 through the storage hopper 6. The cover plate 10 covering the open end of the mold 3 can effectively prevent the powder from scattering onto the workbench 4. After the discharge is completed, the discharge mechanism 5 is slid backward so that the discharge mechanism 5 and the mold 3 are staggered, and the upper mold 3 is covered. The hand wheel 22 is rotated to move the screw 18 downward to fix the mold 3. The hydraulic telescopic mechanism is controlled by the control panel 20 to drive the workbench 4 to move up and down to press the powder in the mold 3 into tablets.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
