a driving mechanism for driving the sliding sleeve to move horizontally is arranged on the platform and comprises a mounting plate and a driving motor; the mounting plates are mounted at two ends of the platform, the guide rods are horizontally mounted between the mounting plates, and the sliding sleeves are slidably sleeved on the guide rods, so that the sliding sleeves can be prevented from being deviated when moving horizontally; still install the screw rod between the mounting panel, install drive screw pivoted driving motor on the mounting panel of one end wherein, the sliding sleeve is connected with the screw rod, and driving motor drives the screw rod and rotates, and the screw rod drives the sliding sleeve removal again, thereby the sliding sleeve drives the spiller and thinks that the printing product removes to will print the product and shovel.

As a further aspect of the present invention: bearing blocks are installed at two ends of the screw rod, so that the screw rod can rotate more stably.

As a further aspect of the present invention: the scraper knife is connected with the sliding sleeve through a bolt, so that the scraper knife is prevented from moving.

As a further aspect of the present invention: the scraper knife is made of stainless steel.

As a further aspect of the present invention: the handle is installed to the spiller upper end, and the dismouting is more convenient.

The utility model has the advantages that:

1. the utility model arranges a sliding sleeve which can slide horizontally on the platform, and a scraper knife is arranged in the sliding sleeve; the scraper knife on the sliding sleeve is driven by the driving mechanism to translate along the upper end face of the platform, so that the printed finished product on the platform can be scraped, and the printed finished product is separated from the platform; manual shoveling is not needed, so that the labor is saved;

2. meanwhile, the screw is used for transmission, the scraper knife advances at a constant speed, the cutting force is stable, the smoothness of the bottom surface of a printed finished product can be ensured, and the quality and the attractiveness of the finished product are ensured;

3. the scraper knife and the sliding sleeve are detachably mounted, so that the scraper knife can be quickly disassembled and assembled, and is convenient to replace and maintain.
