[0038] This invention is a novel planar paper rotation mechanism, particularly for the rotation of paper financial products. Combined with a cutting box mechanism, it removes the waste edges of the financial products, changing the traditional method of three-sided cutting box waste edge removal and providing a completely new way to remove waste edges along the cutting line.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figures 1-3 As shown, this embodiment of the invention provides a planar paper rotation mechanism suitable for paper financial products.

The paper financial product trimming production line includes a paper feeding device 8, a conveying panel 9, a paper walking 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 rotary 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 walking power shaft 10. The lower follower rotary 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 equipped with a paper financial product conveying pressure strip 2, an upper rotating pressure plate mechanism 4, and a rotating lifting mechanism 5.

[0041] After the main equipment on the paper financial product edge trimming production line is powered on, the paper financial product is conveyed to the flat paper rotating mechanism 6 through the paper feeding device 8. The upper rotating pressure plate 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, and the upper rotating pressure plate mechanism 4 is started to rotate 90° counterclockwise to trim the right side. The upper rotating 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 for waste edge removal through the paper walking power shaft 10.

[0042] After cutting off the waste edge on the right side, the paper financial product is pulled back to the rotating position by the paper walking power shaft 10. The upper rotating pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5. The paper walking power shaft 10 is moved out of the rotation range. The upper rotating pressure plate mechanism 4 is started to rotate 180° clockwise to cut the left side. The upper rotating pressure plate mechanism 4 is raised by the rotating lifting mechanism 5. The paper financial product is pushed to the cutting knife box 11 by the paper walking power shaft 10 for waste edge removal.

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

[0044] like Figure 4 As shown, in this embodiment of the invention, the planar rotating mechanism support frame 1 and the production line support frame 7 are connected by locking bolts. After debugging, the two frames are welded together to ensure that no vibration or other unnecessary movements occur during equipment use. The planar rotating mechanism support frame 1 is made of solid carbon structural steel. The planar rotating mechanism support frame 1 includes: a vertical connecting column 101, an upper horizontal connecting beam 102, a lower horizontal connecting beam 103, a guide rail mounting plate 104, and a cylinder mounting plate 105. The vertical connecting column 101 connects to the production line support frame and forms a frame structure with the upper horizontal connecting beam 102 and the lower horizontal connecting beam 103. The guide rail mounting plate 104 and the cylinder mounting plate 105 are mounted on this frame structure. The upper rotating pressure plate mechanism 4 and the rotating lifting mechanism 5 are mounted on the guide rail mounting plate 104.

[0045] like Figures 5-6 As shown in the embodiment of the present invention, the paper financial product conveying strip 2 is used to place on the surface of the paper financial product to prevent the paper financial product from curling or warping during rotation and conveying. The paper financial product conveying strip 2 includes: a mechanism mounting plate 201, a first lifting cylinder 202, a right-angle connector 203, and a stainless steel strip 204. The mechanism mounting plate 201 is mounted on the planar rotating mechanism support frame 1. The first lifting cylinder 202 is mounted on the mechanism mounting plate 201. One side of the right-angle connector 203 is connected to the output end of the first lifting cylinder 202, and the other side of the right-angle connector 203 is connected to the stainless steel strip 204. The stainless steel strip 204 contacts the paper financial product. When the paper financial product passes by, the first lifting cylinder 202 extends, causing the stainless steel strip 204 to descend and make slight contact with the paper financial product.

[0046] like Figures 7-8As shown in the embodiment of the invention, the lower follower rotary disk mechanism 3 includes: a rotary disk connecting base plate 301, a lower rotary disk 302, and a load-bearing angular contact bearing 303. The rotary disk connecting base plate 301 is mounted on the support frame of the production line, and the load-bearing angular contact bearing 303 is mounted on the rotary disk connecting base plate 301. The machining clearance of the rotary disk connecting base plate 301 ensures the fit between the two. The lower rotary disk 302 is mounted on the load-bearing angular contact bearing 303. It is necessary to ensure that the frictional force of the follower rotation is not greater than the frictional force of the paper surface itself, and to ensure the running space between the various components. The lower follower rotary disk mechanism 3 is used for auxiliary rotation during the rotation of the upper rotary pressure plate. The lower follower rotary disk mechanism 3 is mounted on the support frame of the production line and is part of the conveying panel. The lower follower rotary disk mechanism 3 is slightly higher than the conveying panel. It is necessary to ensure the smooth rotation of the paper financial products and the smoothness of paper conveying before and after rotation, and to avoid the financial paper curling or warping.

[0047] like Figure 9 As shown in the embodiment of the present invention, the upper rotating pressure plate mechanism 4 includes: a lifting guide rail slider 401, a rotating frame 402, a servo motor 403, a cycloidal reducer 404, and an upper pressure plate 405.

The end of the cycloidal reducer 404 is connected to the upper pressure plate 405, and the rotational power is transmitted to the paper financial product through the upper pressure plate 405 to realize the rotational action of the paper financial product. 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 upper pressure plate 405 has openings on its surface and the surface is flat.

[0048] like Figure 10 As shown, in this embodiment of the invention, the rotary lifting mechanism 5 includes: a second lifting cylinder 501, a cylinder connecting seat 502, a cylinder front end shaft connector 503, and a connecting seat 504. The connecting seat 504 is installed on the back of the rotary frame 402. The cylinder front end shaft connector 503 is connected to the connecting seat 504. The second lifting cylinder 501 is connected to the cylinder front end shaft connector 503. The lifting and pressing actions of the rotary frame 402 are controlled by the second lifting cylinder 501. The intake volume and pressing force are adjusted by the exhaust throttle valve and the air control valve at the two intake ports of the second lifting cylinder 501.

[0049] Combination Figures 1-10 The planar paper rotating mechanism of this invention is specifically used for:

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

[0051] After the waste edge on the right side is cut off, the paper financial product is pulled back to the rotating position by the paper walking power shaft. The upper rotating pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the second lifting cylinder 501 of the rotating lifting mechanism 5. The paper walking power shaft is moved out of the rotation range. The servo motor 403 of the upper rotating pressure plate mechanism 4 is started, which drives the upper pressure plate 405 to rotate 180° clockwise, so that the left side of the paper financial product faces forward. The upper rotating pressure plate mechanism 4 is raised by the second lifting cylinder 501. The paper financial product is pushed to the cutting knife box for waste edge removal by the paper walking power shaft.

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

[0053] As a novel production method for cutting lines, the planar paper rotating mechanism provided by this invention is the core mechanism of a "one-to-one" production line. Large sheets of financial paper are manually loaded and then conveyed to the working area of ​​the planar paper rotating mechanism via a conveyor. The planar paper rotating mechanism rotates and repositions the product, achieving the removal of waste edges on both sides, thus saving on the number of cutter boxes and reducing the floor space required. Existing planar rotating support frames are relatively unstable vertical frames on a standalone planar paper rotating mechanism. However, due to the presence of the paper travel drive shaft, the two mechanisms are connected, forming a three-dimensional spatial frame mechanism, ensuring stability during lifting and rotation.

[0054] After the conveying mechanism transports the product to the working area of ​​the flat paper rotating mechanism in this embodiment of the invention, the flat paper rotating mechanism receives a signal and its own program starts running. The rotating lifting mechanism 5 operates, lowering the upper rotating pressure plate mechanism 4 to contact the large sheet of financial product. The conveying mechanism then moves out of the product's rotating working range. Upon reaching the designated position, the flat paper rotating mechanism's own program runs, the servo motor 403 starts working, driving the upper pressure plate 405 to rotate counterclockwise by 90° so that the right side of the paper financial product faces forward. The rotating lifting mechanism 5 then drives the upper rotating pressure plate mechanism... 4. Lifting: By opening holes and leveling the surface of the upper pressure plate 405, the mechanism can prevent negative pressure from being applied to the financial product during the lifting process, thus avoiding misalignment and suction. After lifting, the paper travel drive shaft pushes the product to the cutting knife box for side cutting. After completion, the paper travel shaft pulls the product back to the working area of ​​the planar paper rotation mechanism and repeats the above work to continue cutting the side of the product. After both sides are cut, the product is pulled back to the rotation working area, the rotation mechanism resets the product, and then the X-axis cutting and conveying mechanism pushes the product to cut the two front and rear sides and perform the cutting work.

[0055] This invention also provides a method for rotating flat paper suitable for paper financial products. The method includes a flat paper rotating mechanism 6, which is installed on a support frame 7 of a 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 walking power shaft 10, a cutting knife box 11, and an X-axis paper pushing mechanism. The flat paper rotating mechanism 6 includes a flat rotating mechanism support frame 1 and a lower follower rotating disk mechanism 3. The flat rotating mechanism support frame 1 is installed on the support frame 7 of the production line and connected to the paper walking 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 flat rotating mechanism support frame 1 is equipped with a paper financial product conveying pressure strip 2, an upper rotating pressure plate mechanism 4, and a rotating lifting mechanism 5.

[0056] like Figure 11 As shown, the method for rotating a flat sheet of paper includes:

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

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

[0059] S3. After cutting off the waste edge on the left side, the paper financial product is pulled back to the rotating position by the paper walking power shaft 10. The upper rotating pressure plate mechanism 4 is lowered to the surface of the paper financial product and pressed by the rotating lifting mechanism 5. The paper walking power shaft 10 is moved out of the rotating range. The upper rotating pressure plate mechanism 4 is started to rotate 90° counterclockwise and return to the normal conveying position. The upper rotating pressure plate mechanism 4 is raised by the rotating lifting mechanism 5. 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 specific advantages:

[0061] 1. In the field of paper financial products, banknotes have cutting edges on both sides, which need to be removed by a cutting box. The traditional cutting mechanism is a three-sided cutting box mechanism, which occupies a large area and is costly. This invention rotates the paper clockwise and counterclockwise so that the two sides are aligned with the cutting box, and the waste edges on both sides are removed. The cutting box mechanism that needs to be cut is reduced to one set. The method of this invention is applicable to all fields that require the rotation of flat paper products.

[0062] 2. The mechanism provided by this invention can rotate the paper plane to transfer the waste edges that originally needed to be cut on both sides to the product's travel direction, greatly saving the production line's floor space. The rotation action eliminates the need for adjusting the width of both sides to accommodate various products, significantly reducing on-site production line changeover work; it can be completed simply by switching control modes. The mechanism provided by this invention can also eliminate the need for a side-cutting box device, reducing debugging difficulty and the overall production line failure rate.

[0063] 3. The novel method introduced by this invention pioneers a new edge trimming technique for cutting lines. This invention employs a rotary disc clamping friction mechanism, using a cylinder to descend and press the product. Servo rotation is achieved through surface friction. The force with which the cylinder descends and presses the product can be adjusted by increasing or decreasing the air pressure. Due to the special nature of paper financial products, rotation must not cause scratches or other damage. The rotation angle can be adjusted as needed; both forward and reverse rotation are possible. After rotation, the rotary disc is raised, preventing misalignment or separation of the paper financial products.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
