Granular preparation quantitative subpackaging device

The utility model provides a granular preparation quantitative subpackaging device which comprises a dispensing mechanism, and the dispensing mechanism comprises a cavity used for temporarily containing a preparation; the first sliding block and the second sliding block move relatively to control the volume of the cavity and move synchronously to transfer the preparation; and the driving mechanism is used for respectively driving the first sliding block and the second sliding block to do relative movement and synchronous movement. The driving mechanism is arranged to drive the first sliding block and the second sliding block to do relative movement and synchronous movement respectively, the volume of the cavity used for temporarily containing the preparation is variable, and meanwhile the quantitative precision of the quantitative subpackaging device on the granular preparation can be improved. 本实用新型提供了一种颗粒制剂定量分装装置，包括调剂机构，所述调剂机构包括：空腔，用于临时容纳制剂；第一滑块和第二滑块，相对运动以控制空腔容积、同步运动以转移制剂；还包括用于分别驱动第一滑块、第二滑块进行相对运动和同步运动的驱动机构。
