Sheet feeding device

The utility model relates to a sheet feeding device which comprises a rack, an unwinding mechanism, a first guide mechanism, a flattening mechanism, a second guide mechanism and a compression roller set. The flattening mechanism comprises more than one pressing rod; one end of the pressing rod is fixed on the first fixing part through a fastener; the pressing roller set comprises an upper pressing roller and a lower pressing roller. The utility model has the advantages that: (1) the structure is simple, the disassembly and assembly are convenient, and the flattening mechanism and the compression roller group are arranged to flatten the unreeled sheet twice, so that the flatness of the sheet before compounding is ensured; and (2) feeding of the sheets is facilitated, the sheets can rapidly and manually penetrate into the gap between the flattening mechanism and the compression roller set in the initial stage of overhauling or feeding, and the situation that the flattening effect is affected due to the fact tha
