[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 6 shown, the present invention provides a book cover flap forming device, which includes a book transmission mechanism 1 fixedly arranged inside a flap machine. The book transmission mechanism 1 can drive the movement of the book, and the book transmission mechanism 1 adopts the prior art and its structural principle will not be described in detail. At the same time, a separation device for separating the two covers of the book from the book pages is also arranged inside the flap machine, so that the two covers respectively enter into two cover entry ports 13.

[0027] Fixing sleeves 2 are fixedly arranged at the four corners of the installation end of the book transmission mechanism 1. A moving column 3 is longitudinally slidably arranged inside the four fixing sleeves 2. Threaded fastening bolts 8 are arranged on the surfaces of the four fixing sleeves 2. The rod part of the fastening bolt 8 is located inside the fixing sleeve 2, and the end part of the fastening bolt 8 abuts against the surface of the moving column 3 to fix the moving column 3. Folding plates 5 are fixedly arranged at the upper ends of two of the moving columns 3, and angle plates 4 fixedly arranged at one end of the two folding plates 5 are fixedly arranged at the upper ends of the other two moving columns 3. The surfaces at the connection parts of the angle plates 4 and the folding plates 5 are both smoothed and are in the same plane, so that the folded covers can smoothly pass through the connection parts of the angle plates 4 and the folding plates 5.

[0028] By arranging the longitudinally movable moving column 3, the angle plates 4 and the folding plates 5 can be driven to move longitudinally, so that the flap device can adjust the folding opening according to the sizes of different books. At the same time, one end of a support plate 7 can also be connected to the movable end of a linear driving mechanism (not shown in the figure), and then adjusted according to the size of the book, so that the two covers can be smoothly folded.

[0029] A support plate 7 is inserted inside the lower ends of the angle plate 4 and the folding plate 5. The upper and lower ends of the support plate 7 are both provided with rounded corners to reduce the friction with the side of the cover and effectively protect the cover from damage. The contact positions of the angle plate 4, the folding plate 5 and the cover are all provided with smooth surfaces and rounded corners. One end of the support plate 7 is fixed to the inner wall of the flap machine, and the connection method of one end of the support plate 7 can be set according to actual needs. The other end of the support plate 7 is suspended, so that the cover with the folded edge is separated from the support plate 7 and moves to the next process. A cover inlet 13 for the book pages to enter is provided between the support plate 7 and the first hypotenuse 6. The support plate 7 intersects with the first hypotenuse 6. This intersecting setting enables the cover to be bent at 90 degrees. The book pages are arranged between the support plate 7 and the second hypotenuse 10. When the second hypotenuse 10 extends towards the angle plate 4, the distance between it and the support plate 7 gradually becomes smaller, so that the cover is bent at 180 degrees, and one end of the book pages is folded by the limit of the support plate 7; The book pages are the cover.

[0030] On one side of the horizontal end of the folding plate 5, a first hypotenuse 6 is provided. The surface of the first hypotenuse 6 in contact with the cover is provided with a rounded corner to facilitate the passage of the cover and protect the cover. On one side of the vertical end of the folding plate 5, a third hypotenuse 11 is provided. The surface of the third hypotenuse 11 in contact with the cover is provided with a rounded corner to facilitate the passage of the cover and protect the cover. On one side of the vertical end of the folding plate 5 located on one side of the support plate 7, a second hypotenuse 10 is provided. On one side of the end of the angle plate 4 facing the support plate 7, an elastic plate 9 corresponding to the support plate 7 is fixed. The surface of the elastic plate 9 and the surface of the second hypotenuse 10 are smoothly transitioned to facilitate the passage of the cover after the folded edge. There is a gap for the deformation of the elastic plate 9 between the upper end of the elastic plate 9 and the surface of the angle plate 4.

[0031] It also includes an adjustment mechanism 12 for adjusting the elastic plate 9. The adjustment mechanism 12 includes a fixed seat 122 fixed on the side of the elastic plate 9 away from the folding plate 5. One end of the fixed seat 122 is provided with a T-shaped groove 123. A T-shaped column 124 is rotatably arranged and limited in the T-shaped groove 123. A screw 121 that abuts against one end of the T-shaped column 124 is threadedly arranged at the relative position of the angle plate 4 and the T-shaped column 124.

[0032] The principle and process of the present utility model:

[0033] When the covers at both ends of the book enter the cover inlet 13, the book is moved under the drive of the book transmission mechanism 1. First, the cover will move in the cover inlet 13 and abut against the first hypotenuse 6 and continue to be tightly abutted. Subsequently, under the limit of the support plate 7, the cover is bent at 90 degrees above the support plate 7. Subsequently, the support plate 7 is wrapped by the cover and the folded edge slides on the surface of the support plate 7;

[0034] When the upper part of the bent cover contacts the third hypotenuse 11 and slides on the surface of the third hypotenuse 11 and keeps the upper part of the cover intact. When it is finally bent at 180 degrees, the upper part and the lower part of the cover are flush. At this time, the bent cover will enter between the second hypotenuse 10 and the support plate 7;

[0035] The bent cover moves continuously on the surface of the second bevel edge 10 and is squeezed by the second bevel edge 10, causing the upper and lower parts of the cover to slowly fit together. Subsequently, the bent cover enters between the corner plate 4 and the elastic plate 9. The distance between the elastic plate 9 and the support plate 7 is smaller. When the bent cover passes through, the elastic plate 9 can squeeze the flap to make the upper and lower parts of the cover fit more tightly, improving the effect of the flap.

[0036] The user can rotate the screw 121 through the sleeve tool. The rod part of the screw 121 rotates and moves on the corner plate 4. The end face of the rod part of the screw 121 rotates and pushes the T-shaped column 124 and the fixing seat 122 to move on the surface of the T-shaped column 124, thereby pushing one end of the elastic plate 9 to move and then changing the distance between the elastic plate 9 and the support plate 7. This distance can be set according to the thickness of the cover, which can better crimp the cover and prevent the cover from warping at the end of the crimping.

[0037] With the above settings, the device can realize the formation of the flap of the booklet through the folding plate 5, the corner plate 4 and the elastic plate 9, and can continuously crimp the flap, effectively improving the working efficiency of the device and the forming effect of the flap.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
