[0051] (1) By setting up a cleaning mechanism, the two sides of the solid box are in close contact with the transmission belt of the feeder through the clamping strips, and the static electricity is eliminated by the electrostatic fan. The air circulation inside the two sides of the solid box can avoid the problem of powder raw materials floating. At the same time, the air flow is used to drive the brush roller to rotate, and the residual impurities on the surface of the transmission belt can be cleaned.

[0052] (2) By setting up a spray assembly, liquid water can be sprayed on the surface of the transmission belt using a nozzle and a spray hole, further improving the cleaning effect. The rubber roller rotates synchronously with the transmission belt, and the rotating rod can be used to drive the spiral rod to rotate to pressurize the liquid water, thereby improving the spraying effect, and the spraying effect is ensured by increasing the spraying speed.

[0053] (3) By setting up a reflux component, the air inside the fixed boxes on both sides circulates through the circular sleeve, the reflux pipe and the circular hole. During the flow, the water vapor in the air can be recovered through the sponge column to avoid moisture on the surface of the transmission belt. In addition, since the circular holes are set at equal angles, they can automatically adjust their positions by gravity after absorbing full load of water vapor.

[0054] (4) By setting up a water squeezing unit, when the circular hole is aligned with the fixed sleeve through rotation, the sliding rod pushes the sliding column into the circular hole, and can cooperate with the filter plate to squeeze the sponge column, so that the water vapor absorbed by the sponge column is condensed and discharged, so that the sponge column can perform continuous filtering.

[0055] (5) By setting up a driving module and utilizing the connection between the missing gear and the rotating shaft, the kinetic energy of the rotation of the circular plate can be recovered, and through the transmission of the sliding frame, the push block drives the sliding rod to move through the effects of gravity, magnetism and friction, thereby providing driving force for the water squeezing work.
