Cooling circulation water tank system of engraving machine

The utility model discloses an engraving machine cooling circulation water tank system which comprises a water tank base, a first flow channel and a second flow channel are arranged in the water tank base, and the input end of the first flow channel is communicated with an inner cavity of an engraving machine through a filtering device. The output end of the first flow channel communicates with an inner cavity of the carving machine through a first circulating water pump and a first water outlet pipe to form a first cooling circulating water path. The input end of the second flow channel communicates with the interior of the spindle motor through a second water inlet pipe, and the output end of the second flow channel communicates with the interior of the spindle motor through a second circulating water pump and a second water outlet pipe to form a second cooling circulating water path. The cooling circulation water tank system of the carving machine has the advantages of being high in integration degree and
