The large-convolution paper cutter is an important machine in a high-speed automatic production line of toilet paper and kitchen paper, and can greatly improve the automation degree and the production efficiency of the production line.
At present, the feeding mode of a large-convolution paper cutter is that single paper stock independently feeds, in order to ensure the smoothness of the edges of two ends of a finished product, the head and the tail of the paper stock need to be cut off, and because two continuous position detection feedbacks close to the paper head and the paper tail of a long-strip paper stock are lacked, a control system cannot know the accurate position of the paper stock, the next paper stock can be fed into a paper inlet only after the last paper stock is cut off in the feeding process, the paper head and the paper tail of each long-strip paper stock need to be discharged twice, and the efficiency is lower.
In order to improve the efficiency and remove the head and the tail of the paper material more quickly, a double-machine continuous working mode is adopted, namely, the head and the tail of the paper material are cut off by a first paper cutting machine independently, and then the treated paper material is put into a second paper cutting machine and cut into small sections according to the size requirement of a finished product. However, the first paper cutter is in an idle running state at a time between the completion of the cutting of the head portion and the cutting of the tail portion, so that the running cost of the paper cutter is increased, the occupied area is large due to the adoption of a double-machine working mode, and each machine needs to be independently provided with an operator to operate, so that the cost is increased.
