The invention discloses an automatic washing
production line for plastic boards. The automatic washing
production line comprises a feeding rack, a washing main
machine and a collecting rack; the automatic washing
production line further comprises a hot
air drying chamber and a
cooling chamber. After the plastic boards are conveyed through the feeding rack into the washing main
machine for washing,
drying through the hot
air drying chamber and cooling through the
cooling chamber are carried out, and discharging is achieved through the discharging rack. The washing main
machine comprises a washing box, a water squeeze roller pair, spraying water pipes and a
brush roller pair which are arranged side by side are arranged in the washing box, the water squeeze roller pair and the
brush roller pair are arranged in a vertically-symmetric mode, and space for the plastic boards to pass through is reserved between upper rollers and lower rollers; the spraying water pipes include the upper spraying
pipe and the lower spraying
pipe, spraying openings of the upper spraying
pipe and the lower spraying pipe point to the plastic boards, a guide plate is arranged between the upper spraying pipe and the lower spraying pipe and connected the adjacent lower roller of the water squeeze roller pair or the
brush roller pair, and a water passing hole is formed in the position, corresponding to the spraying opening of the lower spraying pipe, of the guide plate. According to the automatic washing production line,
high pressure spraying and brush roller washing are used, dust on plastic separating sheets can be rapidly removed, and the plastic separating sheets can be washed more thoroughly, more hygienically, more rapidly and more efficiently.
