Feeding device

The utility model belongs to the technical field of packaging machinery, and discloses a feeding device which comprises a machine frame, at least two sets of sliding pairs are arranged on a platform, and the sliding pairs can be locked; the two ends of the sliding ways are connected with the rack through the fast-assembly sliding pairs, and the distance between every two adjacent sliding ways can be adjusted on the platform; a stock bin is formed above the position between the at least two sliding ways and can be adjusted along with the distance between the sliding ways. The material pushing mechanism is arranged below the slide way and extends towards the material bin area to form at least one pushing block, and the pushing block can move in a reciprocating mode in the extending direction of the slide way. According to the scheme provided by the utility model, the slideway is directly adjusted through the locking structure on the sliding pair, so that the use of relatively expensive electrical elements is av
