The principle of the scheme is as follows: when the parts are processed, the parts firstly enter the cleaning unit and enter the parts in the cleaning barrel, and the cleaning barrel realizes cleaning treatment on the parts in the barrel in the process that the cleaning barrel rotates on the first base; meanwhile, the part moves along the spiral groove in the cleaning barrel correspondingly and moves out from the other end of the cleaning barrel. After the parts are removed from the cleaning barrel, the parts enter the dripping unit and fall onto the filter plate. The filter plate that the slope set up not only can play the effect of filtering moisture content to the part, still transmit the part in order to next processing unit simultaneously. The parts fall to the lower end of the filter plate under the action of gravity, enter the rinsing unit and enter the rinsing barrel. The rinsing bucket carries out rinsing cleaning process once more to the part, and the in-process of rinsing bucket pivoted on the second base, rinsing bucket carries out the degree of depth through centrifugal force to the part and takes off dirty to make the part move according to the spiral groove orbit in the bucket, move to the other end of rinsing bucket and accomplish the cleanness and follow and move out in the rinsing bucket until the part. The parts moving out of the rinsing barrel enter another water dripping unit, the parts fall on a filter plate, and the filter plate filters the parts to remove water; at the same time, the parts slide down the filter plate and enter the drying unit.

The parts enter the drying unit, fall into the rotary drum, the rotary drum is arranged in an inclined mode, the parts correspondingly slide in the drum in the rotating process of the rotary drum, and the parts fall onto the conveying unit from the other end of the rotary drum. The conveying unit finishes the collection and the transfer of the parts so as to facilitate the next processing of the parts. Through the process, the cleaning machine finishes the cleaning treatment of the parts and finishes the treatment of the nickel preplating of the parts.

When the parts enter the drying unit, the rotating drum is a net-shaped rotating drum, so that the air permeability of the rotating drum is good, and the moisture on the dried parts can be evaporated conveniently; in the process of rotating the rotary drum, starting a plurality of fans in the third base to work, wherein one surface of the third base, which is close to the rotary drum, is a net surface, and the fans in the third base directly blow air to the rotary drum through the net surface; therefore, the drying and water removal treatment of the parts by the drying unit is further enhanced. The rotary drum is also internally provided with plush layers at intervals, and the plush layers have good water absorption, so that the surfaces of parts entering the rotary drum can be subjected to mechanical water removal treatment.

And the heater on the baffle is started, and the heat generated by the baffle is directly supplied to the rotary drum, so that the drying effect of the parts is further accelerated. Because the aperture of the baffle through hole is larger than the shaft diameter of the rotating shaft, the baffle has certain mobility on the rotating shaft, the baffle is vertically positioned on the rotating shaft under the action of gravity, in the rotating process of the rotating shaft, under the condition that the baffle rotates or does not rotate on the rotating shaft, a gap is formed between the vertical baffle and the end part of the inclined rotating drum, and the parts in the rotating drum are limited to be orderly moved out through the gap and fall into the conveying unit.

The water dripping units arranged between the cleaning unit and the rinsing unit and between the rinsing unit and the drying unit are used for dewatering and draining the parts in the previous treatment process, so that the sewage on the parts can be prevented from entering the next treatment working section, and the cleaning and dirt removing effects of the parts are improved.

The rotary drum of the drying unit is a reticular rotary drum, and the rotary drum is internally provided with plush layers at intervals, and the plush layers can wipe and absorb water on the surface of the part; the reticular rotary drum has good ventilation effect, and the rotary drum is convenient for removing moisture on parts in the rotating process; a fan in the third base blows air to the rotary drum; in this way, the parts in the drum are further dried and dewatered. In the process of blowing air to the rotating drum by the fan, parts can be uniformly dried due to the rotation of the drum. The heater that sets up on the baffle can heat up the heat treatment to the rotary drum is inside, further accelerated the drying process of part. The drying unit of the scheme has good drying effect through multi-stage and multi-directional drying and dewatering treatment; meanwhile, the parts are dried in a soft mode, and negative effects caused by traditional high-temperature drying treatment are avoided. The plush layer absorbs water, blows air, drains off and is subjected to heat treatment, so that water stain marks flowing down on the surface of the part are avoided while the part is dried, and the surface of the part is protected.

Furthermore, the filter plate is arranged on the support frame in a vibrating manner, and the upper end of the support frame is also provided with a nozzle which faces the upper surface of the filter plate; the filter plate vibrating machine further comprises a first motor used for controlling the vibrating operation of the filter plate.
