The roller set is vertically arranged and conveys the plate bodies. Each roller set comprises at least two water-blocking rollers 10 arranged side by side. A channel for the plate bodies to pass through is formed between the two water-blocking rollers 10. The two water-blocking rollers 10 are vertically arranged. A transmission shaft 20 is arranged axially in the interior of the water-blocking roller 10. The end of the water-blocking roller 10 is provided with an elastic blade 30. The transmission shaft 20 penetrates the elastic blade 30. The elastic blade 30 can elastically deform when subjected to force. The driving member is in driving connection with the transmission shaft 20 at one end of the water-blocking roller 10 and drives the two water-blocking rollers 10 to rotate.
