However, the manufacturing method of the composite wrapping material provided by the technical scheme has the defects of complex production process, high process requirement and high difficulty, high detection difficulty of qualified products and difficulty in removing defective products.
The specific expression is that firstly, no matter the annular opposite die cutting is carried out by using a cutter or laser, a common problem exists, namely, the die cutting depth of the composite wrapping material must be accurately controlled due to the die cutting, for example, the die cutting of an upper die cutting line opening needs to cut through an upper compact layer, a lower compact layer cannot be cut through, and the lower compact layer cannot be cut through, so that the processing precision requirement of the method is high, and the process difficulty is high; secondly, in the production process, whether the process quality of die cutting meets the requirements or not is difficult to detect one by one, and only spot check can be carried out. The problem caused by the method is that when the die cutting depth is not enough or exceeds the standard, a large number of defective products are produced, waste is caused, and the quality control difficulty in the production process is high; thirdly, when the product is delivered to a factory, the die cutting quality of the annular opposite die cutting is difficult to detect one by one, and only selective inspection can be carried out, so that the delivery quality is similar to a nominal value, and the hidden danger that unqualified products flow into the next process cannot be thoroughly eliminated; fourth, if the annular opposite die cutting is carried out by using the cutter, after the cutter works for a period, the control of the die cutting depth of the cutter is finally influenced due to the fact that the adhesive is continuously accumulated on the cutting edge, and risks are brought to the quality control of the production process.
