Filling machine

The utility model discloses a filling machine, which comprises a needle frame and a needle head, wherein the needle frame comprises a through hole through which the needle head penetrates; a first limiting table is arranged on the needle head; the needle frame penetrates through the first limiting table and supports the needle head; and the first limiting table and a body of the needle head can be fixedly connected and can also be integrated, so as to limit relative movement between the first limiting table and the body of the needle head. The downward movement of the first limiting table is limited by the needle frame, so that descending of the needle head is further prevented; and the descending of the needle head caused by loosening of a clamping element can be prevented. Therefore, according to the filling machine, the problem that the needle head in the needle frame of the filling machine easily falls is effectively solved.
