[0038] In the specific use of this embodiment, when it is necessary to press the filter cotton, the adjusting motor 79 is first started by the external PLC, and the output shaft of the adjusting motor 79 rotates to drive the rotating shaft 710 coaxially connected thereto to rotate, and the rotating shaft 710 rotates to drive the pulley 77 coaxially fixed thereto on the same side to rotate, and the rotation of the pulley 77 drives another pulley 77 connected thereto through a belt 78 to rotate, and the rotation of the other pulley 77 drives the rotating rod 76 coaxially fixed thereto to rotate, and the rotation of the rotating rod 76 drives the rotating column 72 coaxially fixed thereto on the same side to rotate, and the rotation of the rotating column 72 drives the two-way screw 73 coaxially fixed thereto to rotate, and the rotation of the two-way screw 73 drives the two connecting rods 74 threadedly connected thereto to move away from or approach each other, and the connecting rod 74 moves under the guidance of the guide block 75 on the same side and the guide groove on the top surface of the working plate 1, and the movement of the two connecting rods 74 drives the two adjusting plates 712 to move away from or approach each other, and when the distance between the two adjusting plates 712 is appropriate, the adjusting motor 79 is turned off by the external PLC;

[0039] Subsequently, the guide motor 53 and the edge pressing motor 65 are started through the external PLC, and the bottom surface of the filter cotton is brought into contact with the top surface of the guide roller 54. The output shaft of the guide motor 53 rotates to drive the guide rod 52 coaxially connected thereto to rotate, and the guide rod 52 rotates to drive the guide roller 54 coaxially fixed thereto to rotate, so that the filter cotton can be guided. At the same time, the output shaft of the edge pressing motor 65 rotates to drive the edge pressing rod 62 coaxially connected thereto on the same side to rotate, and the edge pressing rod 62 rotates to drive the edge pressing roller 63 coaxially fixed thereto on the same side to rotate, and the edge pressing rod 62 rotates to drive the gear 64 coaxially fixed thereto on the same side to rotate, and the gear 64 rotates to drive another gear 64 meshing with it to rotate, and the other gear 64 rotates to drive another edge pressing rod 62 coaxially fixed thereto to rotate, and the edge pressing rod 62 rotates to drive another edge pressing roller 63 coaxially fixed thereto to rotate, so that the two edge pressing rollers 63 can rotate in opposite directions, and the filter cotton can be transported between the two edge pressing rollers 63 through the guiding action of the guide roller 54, and then the filter cotton can be edge pressed.
