Plastic scraping plate

The utility model discloses a plastic scraping plate, which is installed on a coating machine. The plastic scraping plate comprises a flat plate which is parallel with a plastic pin plane of the coating machine. One surface of the flat plate, which is opposite to the plastic pin plane, is provided with pin slots, and the number of the pin slots is not less than that of plastic pins. The pin slots can contain the plastic pins. According to the plastic scraping plate adopting the technical scheme, when the plastic pins of the coating machine are automatically cleaned, the plastic pins are in contact into the corresponding pin slots and are in contact with the flat plate, and thus, residual plastic on the plastic pins can be removed; and meanwhile, slot humps among the pin slots are in contact with the residual plastic in gaps between the plastic pins and the plastic pins, and thus, the residual plastic in the gaps between the plastic pins and the plastic pins can be removed.
