Abstract

The invention provides an overflowing waterfall type sand spraying device which comprises a left sand spraying assembly and a right sand spraying assembly, wherein the left sand spraying assembly andthe right sand spraying assembly are symmetrically mounted and have the same structure; the left sand spraying assembly comprises a sand inlet pipe, a hose, a connector, an adjusting and fixing assembly and a nozzle body assembly; the adjusting and fixing assembly comprises a connecting block, a fixing block, a pressure block, a locking screw, a pin and an adjusting screw; and the nozzle body assembly comprises a nozzle body, a pipe assembly, a clapboard, a guide plate, a spring and a discharge lifting rod. By utilizing the overflowing waterfall type sand spraying device provided by the invention, sand liquid can overflow in the nozzle body and is then guided by the sloped guide plate to form waterfall to be sprayed to workpieces, thereby ensuring that the waterfall formed by the sand liquid is uniform in workpiece cutting regions and long in delivery lift and can effectively arrive at multi-line cutting regions inside large-size workpieces.

Description

technical field [0001] The invention relates to a sandblasting device for a multi-wire cutting machine, in particular to a sandblasting device for a multi-wire cutting machine for Taineng silicon wafers. Background technique [0002] With the upgrade of multi-wire cutting technology for solar silicon wafers, the original mortar wire cutting method has been gradually upgraded to the diamond wire cutting method. Material cutting and diamond wire cutting will also generate a lot of heat, and at the same time, the diamond particles and debris that fall off will affect the cutting accuracy and surface quality, so it is very important to have a uniform and sufficient amount of cooling water. [0003] At present, most solar silicon wafers are sandblasting structures of closed cavity sand liquid extrusion. When forming waterfalls, the lifts on the left and right sides are too small, and the waterfalls are unevenly formed, which cannot meet the technical requirements for high-speed c...
