The filter box 2 can be used more flexibly and can have a larger capacity. For example, the new filter material also uses a double filter material roll solution in the form of a roll. When starting, a new filter material roll has a diameter of 150 mm. At this time, the recovery roll is empty but has to reserve a space of 150 mm in diameter. The rolls must add up to 300 mm in width. The filter box is more flexible and can make full use of the height direction. For example, the recovery roll has a diameter of 150 mm as above, and if the new filter side can set the height to 300, this is the height of the filter box. The material box needs to have the same capacity as the 150 mm diameter filter roll, and its width only needs about 60 mm, so the distance required in the width direction is only 60+150=210 mm, instead of the double roll solution 300 mm, saving 30%.
