Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric punching and embossing, and particularly relates to a high-speed non-woven fabric punching and embossing machine and a production line. Background Art

[0002] During the production process of plain non-woven fabric, heat setting and punching and embossing are often not carried out on the same production line, but are divided into two production lines. One is for heat setting the non-woven fabric, and the other is for punching and embossing. Currently, for the punching and embossing machine, the outer diameter of the punching and embossing roller is usually 15 cm. Limited by the rotation speed of the punching and embossing roller and the preheating efficiency, the punching and embossing speed of the non-woven fabric needs to be controlled below 80 meters per minute to ensure that the temperature during punching and embossing meets the requirements. When the punching and embossing speed is too fast, the non-woven fabric will not reach the specified temperature due to insufficient preheating, which will affect the punching and embossing effect. Currently, the punching and embossing speed of the punching and embossing machine is much lower than the non-woven fabric production speed, resulting in the accumulation of non-woven fabric after production due to untimely punching and embossing. This not only requires more space to accommodate the accumulated non-woven fabric to be punched and embossed, but also affects the production efficiency of the finished non-woven fabric, resulting in low non-woven fabric efficiency. Currently, to solve this problem, usually 2 punching and embossing production lines are set up, which in turn causes one of the punching and embossing production lines to be often idle, reducing the utilization rate of the equipment. Therefore, it is crucial to solve a series of problems caused by the current low punching and embossing speed without increasing the punching and embossing production line. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the defect of low punching and embossing speed of non-woven fabric during the operation of the punching and embossing machine in the prior art, and to provide a high-speed non-woven fabric punching and embossing machine and a production line.
