A filling device for compact and uniform filling of a seam beautifying agent is provided with a
cart, traveling wheels, a seam beautifying agent tank and an agent filling
nozzle are arranged on the
cart, the filling device further comprises a beating mechanism arranged on the
cart and located behind the agent filling
nozzle, and the beating mechanism is used for beating
ceramic tiles in the traveling process of the cart so that the
ceramic tiles can vibrate. The beating mechanism comprises two swing rods arranged on the two sides of the cart respectively and a shifting rod used for shifting the corresponding swing rods to swing, one end of each swing rod is rotationally arranged on the cart, a matching portion allowing the corresponding shifting rod to shift upwards is formed at the other end of each swing rod, and beating pieces are arranged on the lower sides, close to the matching portions, of the swing rods. The striking piece is used for falling under the action of gravity to strike the
ceramic tile after the poking rod pokes the matching part of the swing rod to rotate upwards and break away from the matching part, and the poking rod is fixed on the wheel shaft of the advancing wheel close to the matching part and synchronously rotates along with the corresponding advancing wheel. According to the invention, the filling speed of the
sealant can be increased, and the filled
sealant can be denser and more uniform.
