DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, and "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" is solely for the purpose of distinguishing technical features and should not be understood to indicate or imply relative importance, or to implicitly indicate the number or order of the technical features indicated. "And / or" throughout the text represents three parallel solutions. For example, "A and / or B" means a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0031] In the description of the present invention, if there is a short sentence containing multiple parallel features, the attributive defines the closest feature. For example, "B, C, and E are arranged on A, and E is connected to D" means that B is arranged on A and E is connected to D, and does not constitute a limitation on C. However, attributives that express the relationship between features, such as "spaced arrangement" and "circular arrangement", do not fall into this category. If the word "all" is preceded by an attributive, it means that all features in the short sentence are limited. For example, "B, C, and D are all arranged on A" means that B, C, and D are all arranged on A. In a sentence with an omitted subject, the omitted subject is the subject of the previous sentence, that is, "B is arranged on A, including C" means that B is arranged on A and A includes C.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] The following combination Figures 1 to 5 Embodiments of the present invention are described.

[0034] This embodiment relates to a cover flattening mechanism, comprising: a frame 1, a flattening driver 2, a cover pressing head 3, a cover positioning driver 4, a spine push plate 5, a first cover positioning corner block 61, and a second cover positioning corner block 62;

[0035] The flattening driver 2 is provided on the frame 1.

[0036] The cover pressing head 3 is driven by the flattening driver 2 to move up and down;

[0037] The cover positioning driver 4 is provided on the frame 1;

[0038] The spine push plate 5 is driven by the cover positioning driver 4;

[0039] The first cover positioning angle block 61 and the second cover positioning angle block 62 together form a cover positioning groove 611 in a "U" shape with an opening facing the spine push plate 5.

[0040] The cover flattening mechanism of the present invention realizes positioning before pressing the cover on the top surface of the book core 8 by configuring the cover positioning driver 4, the spine push plate 5, the first cover positioning angle block 61 and the second cover positioning angle block 62, ensuring the accuracy of subsequent lamination of the book core 8 and the cover; after the book core 8 and the cover are positioned, the flattening driver 2 and the cover pressing head 3 press the cover on the top surface of the book core 8 to realize lamination of the cover and the book core 8, and the cover flattening mechanism automatically realizes lamination of the cover and the book core 8.

[0041] The cover flattening mechanism in this embodiment is used to process the cover of the semi-laminated book core 8. The semi-laminated book core 8 cover refers to the state where the bottom surface of the book core 8 is adhered to one side of the cover and the unadhered side of the cover extends vertically upward. In this state, lamination of the top surface of the book core 8 requires folding the other side of the cover upward to the top surface of the book core 8 before completion of lamination. Since the thickness of the hardcover is generally large, the labor intensity during folding the hardcover is relatively high.

[0042] Further, the cover flattening mechanism further includes a pre-pressing strip 7. The pre-pressing strip 7 is arranged to the left of the cover positioning driver 4 and above the spine push plate 5. The pre-pressing strip 7 is inclined, and the inclination direction of the pre-pressing strip 7 is inclined backward and downward. By configuring this pre-pressing strip 7, when the cover moves to the right, the side of the cover that is turned up is pre-folded downward to a certain extent under the inclined guidance of the pre-pressing strip 7, so as to facilitate the subsequent action of the top pressing driver to press the cover tightly.

[0043] Further, the top surface of the cover pressing head 3 is inclined, and the inclination direction of the cover pressing head 3 extends downward along the direction away from the spine push plate 5. By setting the cover pressing head 3 in an inclined form, when pressing the cover above the cover, the inclined cover pressing head 3 can press the part of the cover that exceeds the book core 8 under the top surface of the book core 8, offsetting a certain degree of the upward flipping tendency formed by the elasticity of the cover, thereby reducing the problem of warping deformation of the open side of the cover.

[0044] Furthermore, the first cover positioning corner block 61 is in an "L" shape, and includes a first positioning surface and a second positioning surface for positioning the two side edges of the cover respectively. The first positioning surface and the second positioning surface are provided with a first pad 63 and a second pad 64 respectively. The first pad 63 and the second pad 64 protrude toward the cover positioning groove 611 on the first positioning surface and the second positioning surface respectively. The cover flattening mechanism also includes a cover pad 65, and the cover pad 65 is fixed to the frame 1. The first pad 63 and the second pad 64 are both located above the cover pad 65. A cover extension groove is provided between the first pad 63 and the second pad 64 and the cover pad 65. When the hardcover cover is used to package the book block 8, after the book block 8 is placed on the hardcover cover, the edges of the cover usually protrude from the book block 8, which can better protect the book block 8. In this solution, a first pad 63 and a second pad 64 are arranged on the first cover positioning corner block 61. First, a cover extension groove is formed between the first pad 63 and the second pad 64 and the cover pad 65 on which the cover is placed. Therefore, when the cover and the book block 8 are pushed together by the cover positioning driver 4 through the spine push plate 5, the portion of the cover protruding from the book block 8 can just extend into the cover extension groove, and the book block 8 will be restricted by the first pad 63 and the second pad 64, ensuring that the spine push plate 5 does not push the book block 8 to be flush with the cover. In addition, when the cover pressing head 3 is driven by the flattening driver 2 to press down the upright side of the cover, the first pad 63 and the second pad 64 can also limit the depth to which the cover is pressed down. Therefore, when the cover is tilted downward by the first pad 63 and the second pad 64, it will not cause the cover to tilt too much, resulting in insufficient adhesion between the cover and the book block 8.

[0045] Furthermore, the upper opening of the cover positioning slot 611 formed by the first and second cover positioning corner blocks 61, 62 gradually expands upward. This upwardly expanding upper opening of the cover positioning slot 611 allows for smoother entry of the cover from above, minimizing scratches on the cover edge. Specifically, the upper sides of the first and second cover positioning corner blocks 61, 62 are both chamfered to form this upwardly expanding opening.

[0046] Furthermore, the cover flattening mechanism also includes a corner block adjustment rail 66 and a first corner block slide 67. The corner block adjustment rail 66 is arranged on the frame 1 in the left-right direction. The first corner block slide 67 slides along the corner block adjustment rail 66. The first corner block slide 67 is provided with a slide locking screw hole and a slide locking screw 68 that pass through the first corner block slide 67. The slide locking screw 68 is threadedly connected to the slide locking screw hole, and the tail of the slide locking screw 68 abuts the frame 1. The first cover positioning corner block 61 is provided on the first corner block slide 67. Thus, the position of the first cover positioning corner block 61 can be adjusted by sliding the first corner block slide 67 to accommodate different covers. Moreover, after adjustment, the first corner block slide 67 can be kept fixed by relocking the slide locking screw 68.

[0047] Furthermore, the spine push plate 5 includes a push plate base plate 51, a push plate vertical plate 52, an angle adjustment slide 53, an angle adjustment slide column 54, an angle adjustment connecting rod 55, and an angle adjustment locking pin. The cover positioning driver 4 is driven and connected to the push plate base plate 51. The angle adjustment slide 53 is fixed on the push plate base plate 51. The angle adjustment slide 53 is provided with an angle adjustment sliding hole. The angle adjustment slide column 54 slides along the angle adjustment sliding hole. The angle adjustment slide 53 is provided with an angle adjustment locking screw hole connected to the angle adjustment sliding hole. The angle adjustment locking pin is threadedly connected to the angle adjustment locking screw hole and the tail of the angle adjustment locking pin abuts against the angle adjustment sliding hole. One end of the angle adjustment slide column 54 is hinged to the angle adjustment connecting rod 55, and the angle adjustment connecting rod 55 is hinged to the push plate vertical plate 52. The push plate vertical plate 52 is rotatably connected to the push plate base plate 51. The spine push plate 5 is split into a rotatable push plate base 51 and a push plate upright 52. After the push plate base 51 is mounted on the cover positioning actuator 4, if positioning errors occur, resulting in a significant vertical deviation of the push plate upright 52, the error can be compensated by adjusting the angle between the push plate upright 52 and the push plate base 51. Specifically, to adjust the angle of the push plate upright 52, loosen the angle adjustment locking pin and then slide the angle adjustment slide 54. The angle adjustment slide 54 then rotates the push plate upright 52 via the angle adjustment connecting rod 55, changing the angle between the push plate upright 52 and the push plate base 51. After adjustment, re-tighten the angle adjustment locking screw to re-lock the angle adjustment slide 54, thereby re-locking the push plate upright 52.

[0048] Furthermore, the cover flattening mechanism also includes a cover support plate 56, which is fixed to the frame 1 and is located in front of the spine push plate 5. When the spine push plate 5 is driven to abut against the spine of the cover, a gap 521 is formed between the spine push plate 5 and the cover support plate 56 for the cover to bend, extrude and deform. The pre-pressed fold on the hardcover cover usually has a certain width to ensure that the side of the cover that is not bonded to the book block 8 has less resistance when folding upward. In the case of a certain width, the design of the gap 521 between the spine push plate 5 and the cover support plate 56, that is, between the push plate upright 52 and the spine push plate 5, can provide the corner portion of the cover with a larger bending and deformation space when the cover is bent, thereby further reducing the resistance when bending the cover.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
