This application discloses a counterweight-balanced brush adjustment device for a candy packaging machine, including a frame, a candy-carrying turntable, arrayed candy-limiting holes, and a brush assembly. The brush assembly is connected to the frame via an elastic connecting component. A counterweight balancing mechanism is provided between the brush assembly and the frame. The counterweight balancing mechanism includes a screw connected between the brush assembly and the frame, with a counterweight connected to the middle section of the screw. When the counterweight moves along the screw towards the brush assembly, the weight of the counterweight causes the brush assembly to pull the elastic connecting component downwards. When the counterweight moves away from the brush assembly, the brush assembly returns to its original position and rises under the action of gravity and the elastic connecting component. This counterweight-balanced brush adjustment device, by utilizing the movement of the counterweight along the screw, can flexibly adjust the pressure of the brush assembly for candies of different heights, ensuring a proper cleaning effect for both tall hard candies and short soft candies during the packaging process.
