[0031] A sealing ring 322 is disposed between the baffle 32 and the support sleeve 311 .

[0032] The specific working process of this utility model:

[0033] When in use, the matrix is ​​firstly transported to the matrix inlet 12 of the dripper 1 through the matrix tube 13 in a continuous liquid supply manner, and finally dripped into the cooling solvent from the dripper 1; the liquid medicine is pumped to the connecting pipe 4 through the gear pump 5 and transported to the inner sleeve 33 of the dispensing device 3, and fills the entire sleeve 333. At this time, the liquid medicine forms a certain pressure in the sleeve 333, and the motor 34 is started, and the motor 34 drives the sleeve 333 to rotate. When the through hole 1 3331 of the sleeve 333 is connected with the through hole 2 3121 of the bushing 312, the liquid medicine is discharged from the through hole 1 333 of the sleeve 333. After passing through the second through hole 3121 of the bushing 312, the liquid 331 is discharged to the matrix tube 13 through the discharge port 3111, and then enters the liquid medicine inlet 11 of the dripper 1, and finally discharged from the core cavity of the dripper 1, forming a drop shape under the coating of the surface tension generated by the matrix, and discharged from the dripper 1 into the cooling solvent. When the first through hole 3331 rotates to be disconnected from the second through hole 3121, the liquid medicine stops being transported, thereby achieving the effect of pulse liquid supply. By controlling the speed of the motor 34, the frequency of liquid medicine discharge is controlled, thereby achieving the effect of intermittent liquid discharge.

[0034] A plurality of through holes 3331 are arranged in the sleeve 333 array of the inner sleeve 33, and the inner sleeve 33 is driven to rotate by the motor 34, so that the liquid medicine passes through the discharge port 3111 of the support sleeve 311 in an intermittent manner. The frequency of the pulse liquid supply provided by the distribution device 3 can be directly controlled by controlling the rotation speed of the motor 34. The distribution device 3 has a simple and compact structure, and the speed and accuracy of the pulse liquid supply are high, and the effect of producing capsules is better, which solves the efficiency problem of producing capsules below 3 mm and improves the production efficiency of capsules.

[0035] By providing a retaining spring 313 in the limiting groove 3112 to prevent the limiting sleeve 331 from coming out, and providing a sealing ring 322 between the baffle 32 and the supporting sleeve 311, leakage of the liquid medicine is avoided, the operation of the dispensing device 3 is more stable and reliable, and the production stability of the capsule is improved;

[0036] The liquid medicine is delivered to the dispensing device 3 by the gear pump 5 . The gear pump 5 has a simple and compact structure, a small volume, and reliable operation. The maintenance of the dripping device is simpler and more convenient.
