Description

Technical Field

[0001] The utility model relates to printed matter processing equipment, in particular to an automatic waste cleaning machine. Background Art

[0002] In the production process of printed products, the die-cutting device first cuts out multiple printed product units on the cardboard according to the designed printed product shape, and then transfers them to the waste stripping machine, where the waste stripping machine separates the scraps from the printed product units. In order to avoid the misalignment or falling off of the printed product units during the transfer of the printed product from the die-cutting device to the waste stripping machine, the current die-cutting devices all adopt an incomplete cutting method, that is, after die-cutting, each printed product unit and the scrap are adhered together by small tooth blocks. Therefore, after die-cutting by the die-cutting machine, the entire stack (multiple sheets) of die-cut cardboard needs to be placed on the waste stripping machine for scrap removal, that is, the small tooth blocks between each printed product unit and the scrap are disconnected to separate each printed product unit from the scrap.

[0003] At present, there are more and more personalized customized printed products, and the batch quantity is getting smaller and smaller. Therefore, before cleaning, it is necessary to adjust the position of the cleaning needle of the cleaning template in the cleaning machine according to the layout drawings of different products. The adjustment frequency is relatively frequent. However, the current adjustment method is usually manual adjustment, which takes a long time and has low efficiency, is not conducive to rapid production conversion, and indirectly causes an increase in production costs.
