The working principle of the die cutting machine is as follows: the printing product or the paperboard is rolled and cut into a certain shape by applying a certain pressure through the embossing plate by using a steel knife, a hardware mould and a steel wire (or a template carved by a steel plate). So-called die cutting, which cuts the entire print into individual graphic products; pressing marks or leaving bent groove marks on the printed product by using a steel wire, wherein the mark is called an indentation; the removal of the parts except the certified products is called waste discharge; these techniques may be collectively referred to as die cutting techniques.
The die cutting process is the most commonly used process in the processing process of packaging printed matters, namely, the forming process of combining a die cutting plate by a die cutter according to the design pattern of a product and rolling and cutting the printed matters or other ring-packed blanks into required shapes or cutting marks 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. The main process of the die cutting process comprises the following steps: the method comprises the steps of printing, adjusting pressure → determining a gauge → pasting a base material auxiliary material → testing pressure and die cutting → formal die cutting indentation → waste clearing → finished product rolling or sheet cutting → counting and packaging.
The die cutting process is the final process of production and is typically used to cut a large imposition print into a plurality of small products. The waste products generated in the process are difficult to select, and great loss is brought to customers. The problems that often appear in the existing die cutting process are as follows: the printed matter is placed in an incorrect direction, the printed matter has shape defects and color defects, the printed matter lacks certain procedures, the concave-convex characteristics on the printed matter cannot reach the standard, and when an error is found on an individual printed matter, the machine needs to be stopped for inspection and adjustment, thereby influencing the production efficiency.
With the market competition becoming more and more intense, the requirements of customers on printed matters become stricter and stricter, and the qualification rate of the printed matters is also continuously improved. The quality detection of the conventional die-cutting machine mainly depends on manual sampling, and the manual sampling has instability, and has human factors such as missing detection or judgment deviation, so that the product qualification rate cannot be guaranteed, and the problem of low sampling speed exists, and the overall production efficiency is influenced.
In view of the above, it is necessary to provide a quality detection device for a die cutting machine to solve the above problems.
