Provided is a tablet-filling device, pertaining to the technical field of pharmaceutical machinery.The tablet-filling device comprises a spiral feeder, multiple layers of flow-guide channels and a tablet control device. The spiral feeder is connected to the tablet control device by means of the obliquely-arranged multi-layer flow-guide channels. The number of the multiple layers of flow-guide channels is the same as that of tablets filled by a single capsule. The number of flow-guide channels in each layer is the same as that of capsule bodies in a capsule lower module. The tablet-filling device has following beneficial effects: the tablet-filling device is capable of intermittently and continuously completing production operation and has simple processes and fine pouring effect; processes and cost are saved; fine sealing effect of capsules is obtained; due to easy dissolution, the capsules are absorbed by people; by cooperative effect among the spiral feeder, a dosage adjusting mechanism, a main body, toggling and clutch mechanisms, dosage for filling and logistics speed can be controlled; the tablet-filling device can timely start or stop filling such that an overall filling process is controllable; and the tablet-filling device occupies little space and requires few people for operation and is easily operated, cleaned and repaired.
