Abstract: PURPOSE: A braid grinder for coating paper is characterized by preventing thin braid from being fold and scratched, controlling an interval between an upper roller and a lower roller to minimize friction between the thin braids and to prevent the roller from being worn out, and improving the expected life span. CONSTITUTION: A braid grinder for coating paper comprises: a base part comprised of a guide block(311) guiding supply and exhaust of a braid, and axis installing members(301,302) installed on one side and the other side; a feed part supplying the braid inserted by rotation of an upper roller and a lower roller supported by the axis installing members; transfer parts transferring the braid supplied from the feed part and containing cylinder pressure upper rollers and lower rollers(332,342,372,382); a pressure part containing crown type upper rollers and steel roller bearings(352,362) and pressure-transferring the braid; a grinding part(50) containing a grinding roll grinding the braid; an exhaust part exhausting the ground braid by rotation of an upper and a lower exhausting rollers installed on ends of the axis installing members(301,302); and a power delivery part delivering driving power originated from a motor(500). The feed part comprises: an upper feed roller block pressurizing a rotating axis of the upper roller; and a feed roller block regulating device pressure-regulating the upper feed roller block. The transfer parts comprise: an upper cylinder part connected and fixed to the axis installing members(301,302) on an upper part of the cylinder pressure upper roller; a cylinder head which is connected with the upper cylinder part, rotatably-holding the cylinder pressure upper rollers by an elastic spring. The exhaust part comprises: the upper feed roller block pressurizing a rotating axis of an upper exhaust roller; and a feed roller block regulating device pressure-regulating the upper feed roller block. The power delivery part comprises: a lower gear of a feed roller containing the upper and the lower rollers; a first lower gear of a first transfer roller at a transfer roller set containing the cylinder pressure upper rollers and the lower rollers; a first driving gear which is geared between a lower gear of the feed roller lower gear and a first lower gear of a first transfer roller, rotation-driving an upper gear of a feed roller ; a second lower gear of a first feed roller and a first upper gear of a pressure roller rotation-driven by the feed lower roller gear geared in the first driving gear and an idle gear; a lower gear of an exhaust roller containing the upper and the lower rollers; a first lower gear of a second transfer roller containing the cylinder pressure upper rollers and the lower rollers; a second driving gear of a feed driving motor which is geared between a lower gear of the exhaust roller and a first lower gear of the second transfer roller , rotation-driving an upper gear of an exhaust roller upper gear; and a first lower gear of an exhaust roller which is geared in the second driving gear and the idle gear, rotation-driving a second lower gear of a second transfer roller and a second upper gear of a pressure roller .
