The inner end of the first wheel rod 1123 is installed on the lower pressure shaft 1122, the outer end of the first wheel rod 1123 is arranged to extend downwardly and tilted, and the outer end of the first wheel rod 1123 forms a first rod head, and the first rod head is used to install the lower pressure wheel 1121, the inner end of the second wheel rod 1124 is installed on the lower pressure shaft 1122, the outer end of the second wheel rod 1124 is arranged to extend downwardly and tilted, and the outer end of the second wheel rod 1124 forms a second rod head, and the second rod head is used to install the lower pressure wheel 1121.

[0032] In this way, under the action of each first wheel rod 1123 and each second wheel rod 1124, the installation of the lower pressure wheel 1121 is realized. At the same time, the first wheel rod 1123 and the second wheel rod 1124 are extended and arranged correspondingly along the lower pressure axis 1122 in opposite directions, so that the overall force of the lower pressure device is balanced and more stable.

Along the axial direction of the down-pressing shaft 1122, the first pressure blocks 1125 are arranged in a corresponding manner at intervals, and the second pressure blocks 1126 are arranged in a corresponding manner at intervals. The first pressure blocks 1125 and the second pressure blocks 1126 are respectively mounted on the down-pressing shaft 1122.

A conveying channel is formed between adjacent limiting rings 1132, and adjacent conveying rings 1131 are arranged to synchronously contact the items to be washed. In this way, under the action of the conveying ring 1131, a driving force for conveying the items to be washed is achieved, which facilitates conveying the items to be washed in a straight line. Under the cooperation of the adjacent limiting rings 1132, the conveying position of the items to be washed is positioned and limited, so as to avoid deviation of the items to be washed during conveyance and ensure that the items to be washed are conveyed in a straight line.

[0036] The conveying ring 1131 and the limiting ring 1132 are integrally formed, which facilitates the production and manufacture of the conveying roller 113 and also facilitates the assembly of the conveying roller 113 .

[0037] A hollow area 114 is formed between adjacent conveying rings 1131 , and the lower pressing wheel 1121 is arranged correspondingly to the hollow area 114 .

[0046] The gap between the partition 21 and the feed belt 23 is smaller than the thickness of the items to be washed, that is, the items to be washed cannot escape from the feed channel 22 through the gap, thereby preventing the items to be washed from erroneously escaping from the feed channel 22 .
