Feeding device and grinding device

The utility model provides a feeding device and a grinding device. The feeding device comprises a base; the supporting plate is used for bearing a silicon rod and is movably arranged on the base; the clamping mechanism is arranged on the base, and the clamping mechanism can be used for clamping the silicon rod; the supporting plate is arranged on the base, the adjusting mechanism is arranged on the base, the supporting plate is connected to the adjusting mechanism, and the adjusting mechanism can drive the supporting plate to move. The technical scheme of the utility model has the advantages that the position of the silicon rod is adjusted by utilizing the adjusting mechanism, so that the feeding precision of the grinding machine is improved, the processing (grinding) precision of the silicon rod is improved, and the silicon loss of the silicon rod is reduced; the width size and the thickness size of the silicon rod can be obtained through the clamping device and the detection mechanism, the grinding amount o
