During work, filter paper passes through the front paper feeding roller set (3) at a specified position by the paper guide stick (1), and then enters the paper receiving-folding mechanism formed by the intersection of protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8), the intersection height of the protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8) is adjusted to conform to an order, and a paper feeding speed is also adjusted to conform to a paper receiving speed. Meanwhile, paper folding is heated and sized by using the heating device (15). In this way, the circumference of the paper feeding roller and the protruding parallel sheets of the conveyer belts all conduct linear motion, and their speeds can be adjusted to be very high, so that the paper folding efficiency can be very high. in addition, as the filter paper folding height can be controlled only by adjusting the intersection height of the protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8), the operation is convenient.
