Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and 2, the solid tablet crushing apparatus includes a hollow accommodating cylinder 11 and a crushing device; the crushing device comprises a rotary driving motor, a rotary column 23, a fixed ring 18, a crushing blade 20, a sliding rod 19, a first connecting rod 17, a grinding sheet 14 and a second connecting rod 15; the side end of the rotating column 23 is provided with a sliding groove, the sliding rod 19 is arranged in the sliding groove in a sliding way, and one end of the sliding rod 19 back to the sliding groove is fixed with the inner side end of the fixed ring 18; one end of the first connecting rod 17 is rotatably connected with the lower end of the fixed ring 18, and the other end of the first connecting rod is rotatably connected with the upper end of the grinding sheet 14; one end of the second connecting rod 15 is rotatably connected with the groove wall of the sliding groove, and the other end of the second connecting rod is rotatably connected with the grinding sheet 14; the number of the pulverizing blades 20 is plural, and the plurality of pulverizing blades 20 are fixedly provided at the side end of the fixed ring 18.
When it is necessary to crush tablets using the solid tablet crushing apparatus, the tablets may be placed in the accommodating cylinder 11. The rotation driving motor drives the rotation column 23 to rotate. Since the sliding rod 19 is slidably disposed in the sliding groove, the sliding rod 19 drives the fixing ring 18 to move slightly in the vertical direction due to the centrifugal force, and the tablet can be crushed when the crushing blade 20 contacts with the tablet. When the fixing ring 18 moves in the vertical direction, the first connecting rod 17 drives the grinding sheet 14 to rotate relative to the second connecting rod, and the tablet powder is positioned between the grinding sheet 14 and the accommodating cylinder 11 and is ground again, so that the obtained powder particles are more uniform and are more favorable for being absorbed by patients.
In order to make the up-and-down movement amplitude of the slide bar 19 larger, the crushing device further comprises an upper elastic member 22, wherein one end of the upper elastic member 22 is fixed with the wall of the slide groove, and the other end is fixed with the slide bar 19.
In order to make the amplitude of rotation of the grinding sheet 14 larger, the crushing device further comprises a lower elastic member 16, wherein one end of the lower elastic member 16 is fixed with the wall of the sliding groove, and the other end is fixed with the grinding sheet 14.
In this embodiment, the grinding sheet 14 has an arc shape, and the convex side and the inner side wall of the accommodating cylinder 11 form a gap for grinding the solid tablet. The arc-shaped rolling sheet 14 is matched with the shape of the inner side wall of the accommodating cylinder 11, so that the grinding of the medicine powder between the two is facilitated.
In the present embodiment, the lower end of the accommodating cylinder 11 is communicated with a powder outlet pipe 110.
In this embodiment, the lower end of the rotary column 23 is provided with a grinding head 12, and the side end of the grinding head 12 is fixedly provided with a lower pulverizing blade 21. The pulverizing blade 21 at the lower end of the rotating column 23 can be more directly contacted with the medicine powder, so that the pulverizing effect is better.
In order to facilitate the installation of the rotary driving motor, the upper end of the rotary column 23 is provided with a screw seat 24, and the output end of the rotary driving motor is fixedly connected with the screw seat 24 in a screw mode.
In this embodiment, the powder outlet pipe 110 is provided with an on-off valve. By controlling the on-off valve, the powder can be evenly ground and then enter the nasal feeding tube from the powder outlet tube 110, and if the particle size does not reach the requirement, the grinding time can be prolonged.
In this embodiment, the lower end of the powder discharge tube 110 is fixedly connected to the nasal feeding tube.
