[0043] After cutting the waste edge on the left side, the paper financial product is pulled back to the rotation position through the paper travel power shaft 10, and the upper rotary pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5, and the paper travel power shaft 10 is moved out of the rotation range, and the upper rotary pressure plate mechanism 4 is started to rotate it 90° counterclockwise and return to the normal conveying position, and the upper rotary pressure plate mechanism 4 is raised by the rotating lifting mechanism 5, and the subsequent strip cutting work is carried out by the X-axis paper pushing mechanism.

[0044] like Figure 4 As shown, in the embodiment of the present invention, the plane rotating mechanism support frame 1 is connected to the support frame 7 of the production line by locking bolts.

The lifting guide rail slider 401 is connected to the rotating frame 402, and the rotating frame 402 is connected to the rotating lifting mechanism 5; the surface of the upper pressure plate 405 is provided with openings and the surface is flat.

[0048] like Fig.10 As shown, in the embodiment of the present invention, the rotating lifting mechanism 5 includes: a lifting cylinder 501, a cylinder connecting seat 502, a cylinder front end shaft joint 503 and a connecting seat 504, the connecting seat 504 is installed on the back of the rotating frame 402, the cylinder front end shaft joint 503 is connected to the connecting seat 504, the lifting cylinder 501 is connected to the cylinder front end shaft joint 503, the lifting cylinder 501 is used to control the lifting and clamping actions of the rotating frame 402, and the exhaust throttle valve and the air control valve at the two air inlets of the lifting cylinder 501 are used to adjust the air intake and the clamping force.

[0049] Combination Figure 1-10 The plane paper rotating mechanism of the embodiment of the present invention is specifically used for:

[0050] After the main equipment on the paper financial product trimming production line is powered, the paper financial product is transported to the flat paper rotating mechanism through the paper feeding device, and the upper rotating platen mechanism 4 is lowered to the surface of the paper financial product and pressed by the lifting cylinder 501 of the rotating lifting mechanism 5, and the paper feeding device is moved out of the rotation range, and the servo motor 403 of the upper rotating platen mechanism 4 is started to drive the upper platen 405 to rotate 90° counterclockwise, so that the right side of the paper financial product faces forward, and the upper rotating platen mechanism 4 is raised by the lifting cylinder 501, and the paper financial product is pushed to the cutting knife box through the paper travel power shaft for waste edge removal;

[0051] After the right side waste edge is cut, the paper financial product is pulled back to the rotation position through the paper travel power shaft, and the upper rotating platen mechanism 4 is lowered to the surface of the paper financial product and pressed by the lifting cylinder 501 of the rotating lifting mechanism 5, and the paper travel power shaft is moved out of the rotation range, and the servo motor 403 of the upper rotating platen mechanism 4 is started to drive the upper platen 405 to rotate 180° clockwise, so that the left side of the paper financial product faces forward, and the upper rotating platen mechanism 4 is raised by the lifting cylinder 501, and the paper financial product is pushed to the cutting knife box through the paper travel power shaft for waste edge cutting;

[0052] After cutting the waste edge on the left side, the paper financial product is pulled back to the rotation position through the paper travel power shaft, and the upper rotating pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the lifting cylinder 501 of the rotating lifting mechanism 5, and the paper travel power shaft is moved out of the rotation range, and the servo motor 403 of the upper rotating pressure plate mechanism 4 is started to drive the upper pressure plate 405 to rotate 90° counterclockwise and return to the normal conveying position, and the upper rotating pressure plate mechanism 4 is lifted by the lifting cylinder 501, and the subsequent strip cutting work is carried out by the X-axis paper pushing mechanism.

[0053] As a new cutting line production method, the flat paper rotating mechanism provided by the present invention is the core mechanism of the "one-to-one" production line. After the large financial paper products are manually loaded, they are transported to the working area of ​​the flat paper rotating mechanism through the conveying mechanism. The flat paper rotating mechanism realizes the waste edge removal work on the left and right sides by rotating and displacing the products, which not only saves the number of knife boxes but also reduces the floor space. The existing flat rotating support frame is a vertical frame with poor stability on a separate flat paper rotating mechanism, but due to the existence of the paper travel power shaft, the two mechanisms are connected to make it a three-dimensional frame mechanism to ensure its stability during lifting and rotation.

[0054] After the conveying mechanism transports the product to the working area of ​​the flat paper rotating mechanism of the embodiment of the present invention, the flat paper rotating mechanism receives the signal, the flat paper rotating mechanism's own program starts to run, the rotating lifting mechanism 5 works, and the upper rotating pressure plate mechanism 4 is lowered to make it contact with the large financial product, and the conveying mechanism withdraws out of the product rotation working range; after reaching the specified position, the flat paper rotating mechanism's own program runs, the servo motor 403 starts to work, and drives the upper pressure plate 405 to rotate counterclockwise, rotating 90° so that the right side of the paper financial product faces forward, and the rotating lifting mechanism 5 drives the upper rotating pressure plate mechanism 4 rises, and by opening holes and leveling the surface of the upper pressure plate 405, the mechanism will not generate negative pressure on the financial products during the rising process, causing the product to be misplaced and sucked up; after lifting, the paper travel power shaft pushes the product to the cutting knife box to cut the side edge, and after completion, the paper travel shaft pulls the product back to the working area of ​​the plane paper rotating mechanism, repeats the above work, and continues to cut the side edge of the product; after both side edges are cut, pull it back to the rotating working area, the rotating mechanism resets the product, and then the X-axis cutting conveying mechanism pushes the product to cut the two front and rear edges and cut the strips.

[0055] The embodiment of the present invention also provides a planar paper rotation method suitable for paper financial products, and a planar paper rotation mechanism 6 is used for implementation. The planar paper rotation mechanism 6 is installed on the support frame 7 of the paper financial product trimming production line. The paper financial product trimming production line includes a paper feeding device 8, a conveying panel 9, a paper travel power shaft 10, a cutting knife box 11 and an X-axis paper pushing mechanism. The planar paper rotation mechanism 6 includes: a planar rotation mechanism support frame 1 and a lower follower rotating disk mechanism 3. The planar rotation mechanism support frame 1 is installed on the support frame 7 of the production line and is connected to the paper travel power shaft 10. The lower follower rotating disk mechanism 3 is installed on the support frame 7 of the production line and is higher than the conveying panel. The planar rotation mechanism support frame 1 is installed with a paper financial product conveying pressure strip 2, an upper rotating pressure plate mechanism 4 and a rotating lifting mechanism 5.

[0056] like Fig.11 As shown, the planar paper rotation method includes:

[0057] S1. After the main equipment on the paper financial product trimming production line is powered, the paper financial product is conveyed to the flat paper rotating mechanism 6 through the paper feeding device 8, the upper rotating platen mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5, the paper feeding device 8 is moved out of the rotation range, the upper rotating platen mechanism 4 is started to rotate 90° counterclockwise, the right side edge is cut, the upper rotating platen mechanism 4 is raised by the rotating lifting mechanism 5, and the paper financial product is pushed to the cutting knife box 11 by the paper travel power shaft 10 for waste edge cutting;

[0058] S2. After cutting the right side waste edge, the paper financial product is pulled back to the rotation position by the paper travel power shaft 10, and the upper rotary pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5, and the paper travel power shaft 10 is moved out of the rotation range, and the upper rotary pressure plate mechanism 4 is started to rotate 180° clockwise to cut the left side edge, and the upper rotary pressure plate mechanism 4 is raised by the rotating lifting mechanism 5, and the paper financial product is pushed to the cutting knife box 11 by the paper travel power shaft 10 to cut the waste edge;

[0059] S3. After cutting the waste edge on the left side, the paper financial product is pulled back to the rotation position by the paper travel power shaft 10, and the upper rotary pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5, and the paper travel power shaft 10 is moved out of the rotation range, and the upper rotary pressure plate mechanism 4 is started to rotate it 90° counterclockwise and return to the normal conveying position, and the upper rotary pressure plate mechanism 4 is raised by the rotating lifting mechanism 5, and the subsequent strip cutting work is carried out by the X-axis paper pushing mechanism.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] 1. In the field of paper financial products, since there are cutting edges on both sides of banknote paper, it is necessary to use a knife box to cut off the waste edges. The traditional trimming mechanism is a three-side knife box mechanism, which occupies a large area and is costly. The present invention rotates the paper clockwise and counterclockwise so that the two side edges are aligned with the knife box, and the waste edges on both sides are cut off, thereby reducing the knife box mechanism that needs trimming to one set. The method of the present invention is applicable to all fields that require rotation of flat paper products.

[0062] 2. The mechanism provided by the present invention can transfer the waste edges that originally need to be cut on the left and right sides to the direction of product travel through the plane rotation of the paper, which greatly saves the floor space of the production line. The mechanism that needs to adjust the width of both sides to adapt to a variety of products is omitted through the rotation action, which greatly saves the adaptation work of on-site production line change, and can be completed by switching the control mode. The mechanism provided by the present invention can omit the side knife box cutting device, reducing the difficulty of debugging and the failure rate of the entire production line.

[0063] 3. The new method brought by the mechanism of the present invention has created a new type of trimming method for the cutting line. The present invention adopts a turntable clamping friction form, and the cylinder descends and presses the product, and the servo rotation is performed through the surface friction. The force of the cylinder descending and pressing the product can be adjusted by increasing or decreasing the air pressure. Due to the particularity of paper financial products, it is required that the product should not be scratched or damaged during rotation. The rotation angle can be adjusted according to demand, and both forward and reverse rotation can be performed.
