Background

The die cutting process is the most commonly used process for packaging printed matters, namely, the forming process of rolling and cutting the printed matters or other ring-packed blanks into required shapes or cutting marks by using a die cutting knife to combine into a die cutting plate according to patterns of product design requirements under the action of pressure. The indentation process is to press line marks on the plate material under the action of pressure by using a line pressing knife or a line pressing die, or to bend and form the plate material according to a preset position by using a line rolling wheel. Generally, the die cutting and indentation process is a process of combining a die cutting knife and a line pressing knife in the same template and simultaneously performing die cutting and indentation processing on a die cutting machine, which is referred to as die cutting for short.

An automatic die cutting waste removing machine is special equipment for realizing a die cutting process, and comprises the working procedures of feeding a plate material, die cutting, removing waste, packaging finished products and the like. The waste cleaning process is to remove the waste materials of the holes and the grooves on the plate processed by the die cutting process, and relates to an upper template, a middle template and a lower template. The upper and lower templates are respectively provided with a punch head at the position corresponding to the hole and the groove of the plate. When different products are replaced, the punches on the upper and lower templates need to be arranged according to the positions of the holes and the grooves of the new product patterns. The common packaging printed matter is generally designed with more than dozens of holes and grooves, and more than 100 holes and grooves, so that the waste template is corrected on the machine once, the waste template is cleaned up and down, the correction time is less, tens of minutes are needed, and more than several hours are needed.
