Detailed Description

Please refer to fig. 1, which is a schematic diagram of the overall structure of the present embodiment, the apparatus includes a housing 10, a feed inlet and a discharge outlet are provided on the housing 10, a grinding mechanism 20 for grinding medicinal materials is provided inside the housing 10, and the medicinal materials enter the grinding mechanism 20 from the feed inlet, and can be ground along with the operation of the grinding mechanism 20, and then discharged from the discharge outlet after finishing the grinding.

As shown in fig. 2 and 3, the grinding mechanism 20 includes a conical cavity 21 disposed below the feed inlet, grinding blades 22 are rotatably connected in the conical cavity 21, the grinding blades 22 are uniformly distributed on a rotating shaft 23, and an upper end of the rotating shaft 23 is fixedly connected with an output shaft of a driving motor 24. In the process of rotating the driving motor 24, the rotating shaft 23 is driven to rotate by matching with the output shaft, and the rotating shaft 23 drives the grinding blades 22 to rotate in the conical cavity 21 so as to grind the medicine entering from the feeding hole; a sieve plate 25 is fixedly arranged at the bottom of the conical cavity 21, and when the ground drug particles accord with sieve holes of the sieve plate 25, the drug particles can directly pass through the sieve plate 25 and then are discharged from a discharge hole.

Further, the grinding blade 22 is rotatably connected to a pressing roller 26 on an end surface of the inner wall near the conical cavity 21, the pressing roller 26 is in contact with the inner wall of the conical cavity 21, and the grinding blade 22 can roll inside the conical cavity 21 along with rotation of the grinding blade. In this embodiment, the medicine adhered to the inner wall can be crushed by the rolling pressing roller 26. A part of the crushed material falls back onto the screen plate 25 and a part is ground under pressure.

As shown in fig. 4 and 5, after the secondary grinding, the medicine is firmly adhered to the inner wall of the conical cavity 21, and in the case of normal grinding, there is a problem that the medicine sticks to the wall, so on the basis of the pressing roller 26, a toggle mechanism 30 is provided on the grinding blade 22, the toggle mechanism 30 includes a fixed frame 31 fixedly installed on the grinding blade 22, the inside of the fixed frame 31 is slidably connected with an L-shaped plate 32, a connecting spring 33 is provided between one end of the L-shaped plate 32 and the inside of the fixed frame 31, the other end is rotatably connected with a connecting rod 34, the connecting rod 34 is provided with a toggle wheel 35 on one end far from the L-shaped plate 32, the angle of the toggle wheel 35 is consistent with the inclination angle of the inner wall of the conical cavity 21, and the toggle wheel 35 can be adhered to the inner wall of the conical cavity 21. In this embodiment, when the driving motor 24 cooperates with the output shaft to drive the rotation shaft 23 to rotate clockwise, the grinding blade 22 also rotates clockwise, and in the process of rotating the grinding blade 22, along the rotating direction, the stirring wheel 35 is in front of the pressing roller 26, the stirring wheel 35 stirs the medicine adhered to the inner wall of the conical cavity 21, and the pressing roller 26 immediately follows again rolls the new medicine for the second time, so as to improve the uniform grinding effect.

Preferably, as shown in fig. 6, the fixing frame 31 is disposed on a radius of a circle formed by the rotation of the rotation shaft 23, and the rotation angle of the connection rod 34 is 0-60 degrees. The connecting rod 34 is provided with a return coil spring. When the angle of the connecting rod 34 is 0 degrees, the connecting rod 34 is at the radius of the rotation shaft 23 at this time, and the connecting rod 34 can be deflected only in the direction in which the rotation shaft 23 rotates clockwise. The dial wheel 35 is thus always in contact with the interior of the conical cavity 21 during clockwise rotation of the grinding mechanism 20. Thus, the click wheel 35 will clean the viscous medicine from the conical cavity 21 both at the beginning and at the end.

However, when the interior of the conical cavity 21 needs to be cleaned after finishing grinding, the driving motor 24 is controlled to rotate reversely, the grinding mechanism 20 rotates anticlockwise, so the grinding blade 22 is driven to rotate anticlockwise, the pressing roller 26 still contacts with the interior of the conical cavity 21, but when the rotation speed is increased, due to the gravity of the poking wheel 35, the circle center deflection angle along the connecting rod 34 is larger along with the increase of the rotation speed, the poking wheel 35 is separated from the inner wall of the conical cavity 21, therefore, in the embodiment, when the grinding device needs to be cleaned, the driving motor 24 starts to rotate reversely, because the speed does not reach the force for driving the connecting rod 34 to deflect, during the period, the poking wheel 35 still contacts with the inner wall of the conical cavity 21, but gradually reaches the highest speed and keeps the speed, the poking wheel 35 is separated from the inner wall of the conical cavity 21 along with the increase of the speed, and when the cleaning is finished, the speed of the driving motor 24 is slowly reduced along with the reduction of the speed, and the speed is reduced according to the formulaIt will be appreciated that as the speed decreases, the centripetal force decreases, and therefore the connecting rod 34 gradually resets and contacts the inner wall of the conical cavity 21 under the action of the return coil spring. This arrangement can effectively protect the click wheel 35 and extend the service life of the click wheel 35 when the grinding device is cleaned. Because the poking wheel 35 is present to solve the problem of sticking the medicine, it is required to be always in contact with the inner wall of the conical cavity 21; in the cleaning process, the poking wheel 35 is not required to be always contacted with the inner wall of the conical cavity 21, so that the poking wheel 35 is arranged to be in contact with the inner wall when the driving motor 24 rotates reversely, the cleaning liquid is firstly used for wetting the inner wall rapidly, the poking wheel 35 is separated from the inner wall when the grinding blade 22 rotates at a uniform speed, the poking wheel 35 is not required to be always contacted with the inner wall in the cleaning process, the cleaning efficiency is not improved, the contact time between the poking wheel 35 and the inner wall is only increased, the service life of the poking wheel 35 is reduced, the speed is reduced when the cleaning work is finished, the poking wheel 35 is in contact with the inner wall again, the poking wheel 35 can rotate for a plurality of circles under the action of inertia force, and at the moment, scales can be effectively removed, so that the poking wheel 35 is protected, and the efficiency of cleaning the conical cavity 21 is ensured.

Furthermore, in the design of the connecting spring 33, when the stirring wheel 35 contacts with the inner wall of the conical cavity 21, under the action of the connecting spring 33, the stirring wheel 35 can be attached more tightly, and the stirring effect of the medicine sticking to the wall can be better.

However, on the basis of the above, there is a problem that, as the grinding blade 22 rotates continuously, although the medicine can be ground to meet the requirement of passing through the screen plate 25, part of the medicine particles are present at the upper end of the grinding blade 22, so that the medicine cannot be completely discharged out of the conical cavity 21, and thus the medicine remains in the conical cavity 21, resulting in waste of the medicine. Therefore, as shown in fig. 8, a purging mechanism 40 is disposed in the conical cavity 21, the purging mechanism 40 includes a toothed ring 41 fixedly mounted on the top of the conical cavity 21, and a fixing rod 42 disposed on the rotating shaft 23, the rotating shaft 23 is rotatably connected in the support cylinder 50, the support cylinder 50 is fixedly connected with the housing 10, the rotating shaft 23 can rotate in the support cylinder 50, a rotating ring 43 is rotatably connected to the bottom of the support cylinder 50, the rotating ring 43 is fixedly connected with the fixing rod 42, the fixing rod 42 can be driven to rotate in the conical cavity 21 when the rotating ring 43 rotates, and a blowing device 421 is fixedly mounted on the end surface of the fixing rod 42 away from the rotating shaft 23, and moves along with the fixing rod 42, during the movement, the blowing device 421 blows the medicine particles on the grinding blade 22, so as to leave the grinding blade 22 and be discharged through the screen plate 25.

Further, as shown in fig. 9, the fixing rod 42 is provided with a power mechanism 422 at one end and outside the air blowing device 421, the power mechanism 422 includes a support plate 4221 fixedly connected with the fixing rod 42, a rotation gear 4222 engaged with the toothed ring 41 is rotatably connected to the support plate 4221, a guide rod 4223 is rotatably connected to an eccentric position of the rotation gear 4222, the air blowing device 421 includes an air cylinder 4211 fixedly connected with the fixing rod 42, and a piston rod 4212 which is disposed inside the air cylinder 4211 and is capable of sliding, and the piston rod 4212 is movably connected with the guide rod 4223. In this embodiment, when the rotating ring 43 is rotated and the fixing rod 42 is matched to drive the air blowing device 421 and the power mechanism 422 to move synchronously, the rotating gear 4222 rotates around the inner wall of the conical cavity 21 due to the toothed ring 41, so that the eccentric guide rod 4223 drives the piston rod 4212 to draw back and forth in the air cylinder 4211 to form an air flow, and the air flow is discharged downwards through the air channel arranged below to blow onto the grinding blade 22, so that particles on the grinding blade 22 can be blown away.

Further, a cleaning roller 4224 is rotatably connected to the lower portion of the support plate 4221, and the cleaning roller 4224 is connected to the shaft center of the rotation gear 4222 and rotates synchronously with the rotation gear 4222. The cleaning roller 4224 plays a role of mechanical cleaning.

The purge mechanism 40 may clean the grinding blade 22, but is not required to rotate continuously with the grinding blade 22, and therefore, a limiting plate 423 is fixedly installed below the fixing rod 42; the connecting ring 424 is fixedly installed on the rotating shaft 23, a sliding groove 4241 is formed in one side of the guide rod extending outwards of the connecting ring 424, a trigger block 4242 is slidably connected in the sliding groove 4241, and a return spring 4243 is arranged between the trigger block 4242 and the sliding groove 4241. In this embodiment, after the trigger block 4242 contacts the limiting plate 423, the rotation shaft 23 drives the rotation ring 43 to rotate under the supporting cylinder 50 due to the limiting effect, so as to complete the above-mentioned actions.

However, because the rotation shaft 23 has a process of acceleration, which indicates that the grinding operation is started, and a uniform speed, which indicates that the grinding operation is in progress, and deceleration, which indicates that the grinding operation is completed, the device is being turned off. As shown in fig. 10, when the centrifugal force acts on the trigger block 4242 to move outside in the sliding groove 4241 and press the return spring 4243, the trigger block 4242 cannot contact the limiting plate 423 due to the change of the position at this time, the rotating ring 43 is not driven to rotate, so that the trigger block 4242 can cooperate with the limiting plate 423 to drive the purging mechanism 40 to work as long as the acceleration process and the deceleration process are performed, and before grinding is started, the purging mechanism 40 can work to blow the medicine to be ground by using gas, so that the puffing treatment is performed, and the subsequent grinding blade 22 is convenient to work; and after finishing the grinding, the purging mechanism 40 is again operated, so that the particles on the grinding blade 22 are blown off. Improving the grinding efficiency of the medicine and avoiding waste. And at the same time, it is avoided that during the grinding process, the operation of the purge mechanism 40 causes the ground medicament to float in the space of the conical cavity 21.

The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
