The fixing plate 20 is provided with an integrally formed arc-shaped rib 25, and the inner surface of the arc-shaped rib 25 is tangent to the outer side of the secondary folding plate 22.

The length of the rotary piece 33 is from the center point of the motor C32 to 1/2-2/3 of the diameter of the fixed plate 20. The distance between adjacent teeth on the rack 4 and the gear 6 is the thickness of 1-2 pieces of filter paper, the distance between the teeth on the rack 4 and the gear 6 is the same, and the length of the rack 4 is larger than the height of the paper storage cylinder 2.

The frame 1 is a hollow structure, and the circuit of the electric control part, the air pressure parts of all cylinders, the circuit and the like are arranged in the frame 1. The electric cabinet of the device is arranged outside, and can be convenient for debugging and setting each parameter. In the device, the connection part is generally fixed by welding or screws, and parts of the connection part can be connected by hardware fittings.

When the paper needs to be folded, the rotatable top plate 3 is pushed open, then the filter paper is placed into the paper storage cylinder 2, and the push plate 8 receives the filter paper. And resetting the top plate 3 and starting the debugged electric cabinet. The motor 7 pushes the push plate 8 upwards through the gear 6 and the rack 4, and the effect of the motor 7 connected with the differential gear can be better and more conveniently controlled. If the differential gear is not used, small current needs to be input in a short time every time, so that excessive filter paper is prevented from being jacked. At this time, the top plate 3 may also be raised to prevent the filter paper from being raised too much, and the distance between the top plate 3 and the top edge of the paper storage cylinder 2 is between the thickness of 2 pieces of filter paper, i.e. slightly higher than the paper pushing plate 13. After the filter paper is jacked up, the motor 7 stops working, and then the cylinder 9 works, so that the paper pushing plate 13 is pushed to separate the filter paper from the filter paper layer. The filter paper layers are loose, so that the possibility of pushing out the filter paper layers simultaneously is generally avoided. The filter paper is further separated by the arc-shaped structure which is thinner than the lower end of the paper pushing plate 13. The filter paper is pushed onto the circular plate and then the cylinder 9 is reset.

When the filter paper reaches the circular plate, the cylinder C30 lifts the motor C32, then the motor C32 drives the rotary piece 33 to come above the fixed plate 20, and then the cylinder C30 descends.

After the primary folding plate 21 is folded, the motor B24 connected with the secondary folding plate 22 is reset, and the motor B24 starts to work and turns over about 160-170 degrees. The arc-shaped rib 25 prevents the filter paper from falling off due to an external force during the folding process. The secondary folding plate 22 is folded and then restored.

Then the cylinder C30 is lifted to bring the folded filter paper to the storage cylinder 40 and enter the paper storage slot, and then the cylinder D36 pushes the piston rod on the needle cylinder 35 to make the air in the needle cylinder 35 enter the balloon 34, thereby spreading the folded filter paper. The balloon 34 is elastic and does not damage the filter paper. The breakage rate of the filter paper in the working process is effectively reduced. The inflated balloon 34 is maintained for a period of 3-5 seconds and then the cylinder D36 is reset and the balloon 34 is also reset.

The cylinder E42 pulls the scraping plate 43 back to scrape the spread filter paper off the rotary blade 33 into the paper storage slot. The stroke of the cylinder E42 is different each time the squeegee 43 is pulled. Or define the same stroke, but a short distance each time. Different modes can be selected according to actual conditions. At this point, a whole process is completed. And the process is repeated again, or the adjustment is carried out according to actual needs.
