Patent ID: 8235032

Claim:
A V-groove processing apparatus for cutting and V-groove processing, comprising a processing unit for processing V-grooves in an engineered stone raw plate fixed on a table while being transferred by a transfer unit, wherein the processing unit comprises: a circular saw blade disposed at a front of a cutting panel to cut the engineered stone raw plate; one or more cutters disposed on a front of a cutter housing to form a V-groove inside a cut surface; a first rise and fall unit transferring the circular saw blade to a cutting location during the cutting of the engineered stone raw plate and restoring the circular saw blade to an original place after the cutting of the engineered stone raw plate; and a second rise and fall unit transferring the circular saw blade and the cutters to a V-groove forming location during the formation of the V-groove and restoring the circular saw blade and the cutters to original places after the formation of the V-groove; wherein the first rise and fall unit comprises: a first screw rod vertically disposed at one side of the cutter housing adjacent to the cutting panel; a first rise and fall motor fixedly disposed at one side of the cutter housing so as not to be interfered with the first screw rod and the cutting panel; a first chain connecting the first screw rod and the first rise and fall motor; and a first screw nut block mounted on one end of the cutting panel adjacent to the first screw rod and penetrated by the first screw rod; and wherein the second rise and fall unit comprises: a second rise and fall motor mounted on an upper portion of a column vertically extending from an upper surface of the cutter housing; a second screw rod comprising one end thereof connected to the second rise and fall motor and the other end thereof connected to an upper portion of the cutter housing along the column; and a second screw block disposed at a rear side of the column and penetrated by the second screw rod.
