[0030] It needs to be explained: the avoiding slot that the inside of fixed frame 3 is equipped with, so that turnover lever 4 can rotate smoothly in the inside of fixed frame 3, will not be blocked, when turnover lever 4 is turned up paper from one end of fixed frame 3 to the other end of fixed frame 3, the next group of turnover levers 4 is ready for the next time overturning work, the paper after overturning moves through flattening roller 5 by conveying roller 6, because the direction of belt drive and gear drive is not identical, so that conveying roller 6 and conveying belt 2 rotation direction are identical, the flattening roller 5 above fixed frame 3 and conveying belt 2 rotation direction are opposite, so it is more helpful to the paper to move forward through flattening roller 5 to reach the conveying belt 2 of discharge end, the design of the chute on collection plate 17 can design the distance of L-shaped clamping plate 7 in the chute according to the size of paper, to ensure that paper can be collected neatly;

[0032] It should be noted that: when the paper is dried on both sides to reach the discharge end of the drying machine body 1, the paper is smoothly slid out through the inclined downward guide plate 20 and falls on the collecting plate 17, at the same time, the positioning mechanism starts to work, the electric push rod 14 drives the rack 15 to move, due to the meshing connection between the rack 15 and the gear one 16, the rotating disc 18 is driven to rotate, the arc-shaped grooves 19 in the rotating disc 18 are slidably connected with the bottoms of the L-shaped clamping plates 7, so that the L-shaped clamping plates 7 can move along with the rotation of the rotating disc 18, along with the movement of the L-shaped clamping plates 7, the paper is positioned on the collecting plate 17 in an orderly manner, the bottoms of the L-shaped clamping plates 7 are slidably connected with the bottom of the collecting plate 17, so that the L-shaped clamping plates 7 can stably move during clamping.

[0033] The working principle of the finished paper rapid drying device for papermaking is as follows:

[0034] I. Paper turning drying:

[0035] The paper on the paper production line is sent to the two symmetrical transmission belts 2 in the drying machine body 1 by the automatic paper feeder, along with the movement of the transmission belts 2, the paper enters the drying area of the drying machine body 1, and here, the paper is subjected to the action of the heat source in the drying machine, and starts to remove excess moisture;

[0036] When the paper reaches the fixed frame 3 at the connection position of the two transmission belts 2, the transmission mechanism starts to work, the motor 8 drives the transmission rod 9 to rotate, and then drives a plurality of groups of turnover rods 4 to rotate synchronously, the rotation of the turnover rods 4 turns the paper from one side to the other side, so that the front and back of the paper can be evenly dried;

[0037] The paper after turning over continues to move forward through the conveying roller 6 inside the fixing frame 3 and passes through the flattening roller 5, the movement of the conveying belt 2 is connected through the meshing of the driving gear 10 and the driven gear 11 and the belt driving connection of the driving pulley 12 and the driven pulley 13, which ensures the synchronous rotation of the flattening roller 5 and the conveying roller 6, the conveying roller 6 and the flattening roller 5 work together to ensure that the paper is flat during conveying, avoiding wrinkling or deformation, and after the paper passes through the conveying roller 6 and the flattening roller 5, it continues to move with the conveying belt 2 through the drying area for drying after turning over;

[0038] II. Collecting the paper neatly:

[0039] When the paper after drying on both sides reaches the discharge end of the drying machine body 1, the paper smoothly slides out through the downward inclined guide plate 20 and falls on the collection plate 17, at the same time, the positioning mechanism starts to work, the electric push rod 14 drives the rack 15 to move, due to the meshing connection of the rack 15 and the gear 1, in turn drives the rotating disc 18 to rotate, the arc-shaped groove 19 inside the rotating disc 18 is in sliding connection with the bottom of the L-shaped clamping plate 7, so that the L-shaped clamping plate 7 can move with the rotation of the rotating disc 18, with the movement of the L-shaped clamping plate 7, they will position the paper neatly on the collection plate 17;

[0040] With the continuous input and collection of the paper, the L-shaped clamping plate 7 continues to move and clamps the new paper. The continuous rotation of the rotating disc 18 makes the L-shaped clamping plate 7 neatly stack the paper on the collection plate 17, when the paper stack on the collection plate 17 reaches a certain number, the paper stack can be removed by manual or automatic mode to continue to collect new paper.

[0041] The above is only an embodiment of the present application, and does not limit the patent range of the present application, any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
