Improvement Method Of Refueling And Cutting Device Of Sanitary Napkin Pe Film Packaging Production Line

1. Production of pe film packaging

In the pe film packaging production line of sanitary napkins, since the pe film packaging material is printed with patterns, it is necessary to ensure that the length of each piece of pe film packaging is consistent with the position of the pattern when cutting, but the ends of the pe film packaging material are usually not complete The pattern, when cutting, the cutter is cut according to a certain time interval, which will cause the new material to be unable to cut the complete pattern when changing the material. At this time, a pendulum bar is needed to adjust the position of the pe film packaging material. Usually, the adjustment amount is 1-2mm each time. According to the coincidence degree of the old and new materials, the guide rod needs to be adjusted a few times or hundreds of times. The coating with incomplete patterns produced during the adjustment process is waste. , because many volumes of coating materials are replaced every day in the coating production line, so more waste of coating materials will be generated during the refueling process, which increases the production cost.

In order to overcome the deficiencies of the existing technology, Jin Tong, Wang Yidong, Li Zhongmian, Wu Jun and others provided a cost-reducing refueling and cutting device for the sanitary napkin coating production line: a device for sanitary napkin coating production line The refueling and cutting device is suitable for the production line provided with the refueling cursor point on the pe film packaging, including a frame, and the adjacent first discharge roller and the second discharge roller are arranged on the frame, and the Both the first discharge roller and the second discharge roller are provided with the coating film, and a material change cutting mechanism is arranged between the first discharge roller and the second discharge roller, and the material change cutting mechanism A refueling sensor and a time delay sensor are set on it.

2. Beneficial effects of the device

By setting the refueling sensor and delay sensor on the refueling and cutting mechanism, when the refueling sensor recognizes the refueling cursor point on the pe film packaging, the refueling and cutting process starts, and the clapper on the refueling and cutting mechanism will The tail material of the pe film packaging to be replaced and the head material of the stock are clapped together, and the delay sensor starts to work at the same time, and provides the recognized distance information between the two cutting cursor points to the delay processing module, The delay time of cutting is converted. When the delay sensor recognizes the first cutting cursor point, it does not cut, and when it recognizes the second cutting cursor point, it cuts again. There is no need to use pendulum in the subsequent process. The rod adjusts the pe film packaging, almost no waste of the pe film packaging material is generated, and the production cost is reduced.
