The layered storage cylinder 44 can be divided into a storage area, a pre-buffer area, a buffer area and a loading area from top to bottom according to four separated layers. In a default state, the exit of the storage area and the exit of the buffer area are blocked by the layered loading frame 43, and the pre-buffer area is not blocked. At the first feeding, the feeding cylinder 42 pushes forward a distance of the width of the discharge port, at which time only the exit of the pre-buffer is blocked, and since the height of the pre-buffer is set to the height of five bearings, when the feed cylinder 42 is retracted to the default position, only the exit of the stocker and the buffer are blocked, the bearings of the stocker do not enter the pre-buffer, all five bearings of the pre-buffer enter the buffer, the first bearing will temporarily stay and fill the empty space when entering the first position of the buffer, the second bearing will roll into the second empty space due to the gradient of the buffer, and so on until all five empty spaces are filled, when the feeding cylinder 42 moves forward the distance, only the pre-buffer outlet is blocked and the bearings are to be cleaned, the bearings in the buffer enter the feeding area at an angle to the vertical and are moved into a specific position of the storage rack 45 to be gripped. The circulation of the feeding and pre-feeding states can be realized by repeating the actions of the feeding cylinder 42.

The upper cleaning gland 63 is evenly distributed with five spray pipes 69. When the bearing clamping device rotates to the station position, the cleaning cylinder 64 pushes the upper cleaning gland 63 down to be closed with the fixed lower cleaning gland 62, the upper and lower glands are provided with parallel slender positioning strips at each bearing position to fix the positions, at the moment, the oil inlet valve 65 is opened, the cleaning agent completes the cleaning action through the oil tank 1, the hydraulic pump 61, the oil inlet header 68, the oil inlet valve 65, the oil inlet pipe branching unit 66, the respective oil inlet pipe 67 and the spray pipe 69, and the sprayed cleaning agent returns to the oil tank through the respective oil return port 610, the respective oil return pipe 611, the oil return pipe branching unit 613 and the oil return header 614 from the oil return port of the oil tank 1 to be reused. After the cleaning is completed, the oil feed valve 65 is closed, and the cleaning cylinder 64 is returned to its original position, at which time the cleaning is completed. As shown in fig. 1, the upper mounting height of the lower blowing hood 96 is identical to the upper mounting height of the lower cleaning hood 62 in the blowing station. The upper air supply gland 95 has the same structure as the lower air supply gland 96, and five air nozzles 97 are uniformly distributed on each air nozzle. When the action is executed, the air supply cylinder 91 pushes down the upper air supply gland 95, the upper gland and the lower gland are provided with parallel slender positioning strips at each bearing position to fix the position of the upper gland and the lower gland, the fan 910 is started, and the air supply cylinder 91 returns to the initial position after the drying is finished.
