With the high-end of diaper production equipment and the messiness of equipment structure, the price of equipment is getting higher and higher, and users have put forward higher requirements for equipment life and utilization. Equipment modularization, on the one hand, will make the equipment upgrade, add new features and product specifications easier, shorter time, lower cost, and then extend the equipment service life, improve equipment utilization, transport users to pay back to the return; on the other hand, to meet the diversity of terminal products on the flexibility of the equipment requirements, improve the conversion efficiency of equipment when users produce different products, reduce downtime and production costs, and then meet the market's demand for terminal product diversity, differentiation, small batches, fast cycles.
