Description

Capsule cutting separator Technical Field The invention relates to the field of capsule manufacturing equipment, in particular to a capsule cutting and separating device for cutting and removing capsule slitter edges. Background The medicinal capsule comprises mutually inserted capsule bodies and capsule caps, and the manufacturing process mainly comprises the steps of sol, glue dipping, demoulding, cutting and the like. As shown in fig. 1, a capsule (including a capsule body and a capsule cap) blank is drawn from a mould column and demoulded, irregular ends exist at the open ends, and the irregular open ends of the capsule blank are cut off as redundant slitter edges. The existing capsule cutting device for cutting the waste edges of the capsule blanks comprises a roller, a cutting die column, an end face cam and a cutter, wherein a plurality of capsule accommodating grooves are formed in the peripheral surface of the middle portion of the roller along the circumferential direction, air suction holes are formed in the bottom of the groove, die column mounting holes corresponding to the capsule accommodating grooves are respectively formed in the roller body on the outer sides of the two ends of the capsule accommodating grooves, the center lines of the die column mounting holes and the center line of the roller are in the same direction, the two ends of the roller are respectively coaxially provided with the end face cam, the end face cam is fixedly arranged, the roller can rotate relative to the end face cam, the cutting die column is accommodated in the die column mounting holes, the front end shape of the cutting die column is matched with the inner cavity of the capsule, the capsule blanks accommodated in the capsule accommodating grooves can be inserted into the inner cavity of the cutting die column when the cutting die column moves forwards, the rear end of the cutting die column is provided with rolling bodies, the rolling bodies are matched with the track surfaces of the end face cam, the roller is driven by the end face cam to move in the die column mounting holes in the axial direction when the roller rotates relative to the end face cam, the end face cam is located on the radial side of the roller, the front of the end face cam, the cutting die column can rotate relative to the end face cam, the front end face cam and the cutting die blanks of the capsules are small in length of the capsule blanks, and the front of the capsule blanks are formed. According to the sequence that the waste edges and the qualified products of the capsules are separated from the cutting die columns, a qualified product collecting channel and a waste edge collecting channel are sequentially arranged on the lateral side of the roller, the qualified products of the capsules are collected firstly, and then the waste edges are collected, so that the separation and the collection of the waste edges and the qualified products of the capsules are realized.
