Description

Technical Field

[0001] The invention relates to the technical field of book cover pasting, and in particular to a synchronous transmission mechanism of a book cover pasting machine. Background Art

[0002] In the book cover production and bookbinding industries, precise alignment of book pages with the book block is crucial for ensuring the quality of the finished product. Traditional cover machines often employ an integrated transmission system, where the same transmission mechanism drives the book page transport, creasing, and alignment with the book block. While this integrated design simplifies the mechanical structure to a certain extent, it can present numerous problems under high-speed conditions.

[0003] Firstly, because the pages and book block need to move synchronously to the bonding station at the same time and speed, the transmission system requires extremely high precision. Traditional integrated transmission systems, when operating at high speeds, can easily lead to inaccurate and unstable alignment between pages and book blocks due to the accumulation of factors such as inertia, friction, and transmission errors between components. This can affect the binding quality of the book and even increase the scrap rate.

[0004] On the other hand, the transmission system of traditional cover machines is usually complex and bulky, especially the part that drives the book pages to fit and align. Since it needs to undertake multiple tasks such as book page transportation, line pressing, and fitting and alignment at the same time, its structure is large and heavy, which not only increases the manufacturing cost and maintenance difficulty of the equipment, but also limits the operating stability and accuracy of the equipment under high-speed conditions.

[0005] In addition, as the bookbinding industry's requirements for equipment versatility and flexibility continue to increase, traditional cover machines often require complex adjustments to the entire transmission system when changing book page sizes, which not only increases the difficulty and cost of equipment adjustments, but also reduces production efficiency.

There is no need to make complex adjustments to the entire transmission system, which greatly improves the versatility and flexibility of the equipment, reduces the difficulty and cost of equipment adjustment, and improves production efficiency.

[0016] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the book cover production and bookbinding industries, precise alignment of book pages with the book block is crucial for ensuring the quality of the finished product. Traditional cover machines often employ an integrated transmission system, where the same transmission mechanism drives the book page transport, creasing, and alignment with the book block. While this integrated design simplifies the mechanical structure to a certain extent, it can present numerous problems under high-speed conditions.

[0021] Firstly, because the pages and book block need to move synchronously to the bonding station at the same time and speed, the transmission system requires extremely high precision. Traditional integrated transmission systems, when operating at high speeds, can easily lead to inaccurate and unstable alignment between pages and book blocks due to the accumulation of factors such as inertia, friction, and transmission errors between components. This can affect the binding quality of the book and even increase the scrap rate.

[0022] On the other hand, the transmission system of traditional cover machines is usually complex and bulky, especially the part that drives the book pages to fit and align. Since it needs to undertake multiple tasks such as book page transportation, line pressing, and fitting and alignment at the same time, its structure is large and heavy, which not only increases the manufacturing cost and maintenance difficulty of the equipment, but also limits the operating stability and accuracy of the equipment under high-speed conditions.

[0023] In addition, as the bookbinding industry's requirements for equipment versatility and flexibility continue to increase, traditional cover machines often require complex adjustments to the entire transmission system when changing book page sizes, which not only increases the difficulty and cost of equipment adjustments, but also reduces production efficiency.

[0024] Regarding the above technical issues, such as Figures 1 to 6 As shown, the present embodiment provides a synchronous transmission mechanism of a cover laminating machine, including a frame body, the frame body is provided with a first feeding table 1 and a second feeding table 2 aligned horizontally, a crimping roller assembly 3 is provided between the first feeding table 1 and the second feeding table 2; the first feeding table 1 is provided with a first slit 4 extending along the feeding direction, a first sprocket assembly 5 is provided below the first feeding table 1, a first chain 6 of the first sprocket assembly 5 is extended along the first slit 4, the first chain 6 is provided with a plurality of first push blocks 7 at intervals, the upper end of the first push block 7 extends out of the first slit 4; the second feeding table 2 is provided with a second slit 8 extending along the feeding direction, the first sprocket assembly 5 is provided below the first feeding table 1, a first chain 6 of the first sprocket assembly 5 is extended along the first slit 4, a plurality of first push blocks 7 are provided at intervals, and the upper end of the first push block 7 extends out of the first slit 4; the second feeding table 2 is provided with a second slit 8 extending along the feeding direction, A second sprocket assembly 9 is provided below the second feeding table 2, and the second chain 10 of the second sprocket assembly 9 extends along the second slit 8. The second chain 10 is provided with a plurality of second push blocks 11 at intervals, and the upper end of the second push block 11 extends out of the second slit 8; a third sprocket assembly 12 is provided on one side of the crimping roller assembly 3; the third sprocket assembly 12 includes a first sprocket 13, a second sprocket 14, a third sprocket 15, a fourth sprocket 16 and a third chain 17 connecting the above four sprockets; the third sprocket 15 is connected to the second sprocket assembly 9 for driving the second chain 10 to move; the fourth sprocket 16 is connected to the first intermediate sprocket 41 rotating coaxially, and the first intermediate sprocket 41 is connected to the third sprocket assembly 12 for driving the crimping roller assembly 3 to move; the fifth sprocket 18 of the first sprocket assembly 5 is connected to the servo motor 19; the second sprocket 14 is connected to the sixth sprocket 20 rotating coaxially, and the sixth sprocket 20 is connected to the transmission box, and the transmission box is connected to an external power.

[0025] The book pages are first placed on the second feed table 2. As the second chain 10 of the second sprocket assembly 9 moves, the second push block 11 begins to move forward. When the second push block 11 contacts the book page, it pushes the page forward. As the page is pushed forward, it passes through the crimping roller assembly 3, which crimps the page so that it can better fit the book block. After the page is crimped, it enters the first feed table 1 area. As the first chain 6 of the first sprocket assembly 5 moves, the first push block 7 begins to move forward. The first push block 7 pushes the page, causing it to move to the laminating station.

[0026] The servo motor 19 drives the entire first sprocket assembly 5, causing the first chain 6 to drive the first push block 7 forward. External power is transmitted to the sixth sprocket 20 through the transmission box. The sixth sprocket 20 drives the second sprocket 14 to rotate. The second sprocket 14, through the third chain 17, drives the first sprocket 13, the third sprocket 15, and the fourth sprocket 16 to rotate synchronously. The fourth sprocket 16 drives the first intermediate sprocket 41 to rotate, which in turn drives the crimping roller assembly 3. The third sprocket 15 drives the entire second sprocket assembly 9, causing the second chain 10 to drive the second push block 11 forward.

[0027] In this embodiment, the process of pressing the book pages and fitting them into position is divided into three motion components for driving, namely the first sprocket assembly 5, the pressing roller assembly 3 and the second sprocket assembly 9. The second sprocket assembly 9 is used to transport the book pages to the pressing roller assembly 3, which is used to press the book pages, and the first sprocket assembly 5 is used to push the book pages after pressing the line to the fitting station and align them with the book core. Since the book pages and the book core need to move synchronously to the fitting station at the same time and speed, extremely high accuracy is required. In this embodiment, the first sprocket assembly 5 is separated from the pressing roller assembly 3 and the second sprocket assembly 9, thereby achieving the lightweighting of the first sprocket assembly 5 for driving the book pages to fit and align. By using a separate servo motor 19 as a drive, high-precision control can be achieved under high-speed conditions, effectively solving the problems of inaccurate and unstable alignment under high-speed conditions.

[0028] The first sprocket assembly 5 is independently controlled by a servo motor 19, facilitating adjustment of the overall phase of the first chain 6 and the first push block 7. When the book block and page sizes change, the first push block 7 can be moved forward or backward as a whole to accommodate pages of varying sizes. This improves the versatility and flexibility of the device and reduces the difficulty and cost of equipment adjustments associated with changing page sizes.

[0029] In some embodiments, the third sprocket 15 is connected to the first shaft 22 through the fourth sprocket assembly 21, and the first shaft 22 is connected to the seventh sprocket 23 of the second sprocket assembly 9; the third sprocket 15 is connected to the coaxially rotating eighth sprocket 24, and the eighth sprocket 24 is connected to the second shaft 26 through the fifth sprocket assembly 25, and the second shaft 26 is connected to the ninth sprocket 27 of the second sprocket assembly 9.

[0030] The third sprocket 15 is connected to the second sprocket assembly 9 via two transmission paths to achieve power transmission. First, the third sprocket 15 is connected to the first shaft 22 via the fourth sprocket assembly 21. The first shaft 22 is further connected to the seventh sprocket 23 of the second sprocket assembly 9. When the third sprocket 15 rotates, the fourth sprocket assembly 21 drives the first shaft 22 to rotate, which in turn drives the seventh sprocket 23 to rotate, partially transferring power to the second sprocket assembly 9. Second, the third sprocket 15 is connected to the coaxially rotating eighth sprocket 24. The eighth sprocket 24 is further connected to the second shaft 26 via the fifth sprocket assembly 25. The second shaft 26 is connected to the ninth sprocket 27 of the second sprocket assembly 9. Thus, when the third sprocket 15 rotates, the eighth sprocket 24 rotates synchronously, which in turn drives the second shaft 26 via the fifth sprocket assembly 25, ultimately driving the ninth sprocket 27 to rotate, further transmitting power to the second sprocket assembly 9. This ensures that the second sprocket assembly 9 can stably and effectively drive the second chain 10 and the second push block 11 to complete the page pushing operation.

[0031] The dual-path transmission method enhances the stability and reliability of power transmission. When one of the transmission paths has a minor fault or is disturbed, the other path can continue to provide power, reducing the risk of equipment downtime due to transmission failure and ensuring the continuity of the page pushing process.

[0032] In some embodiments, a planar gap is provided between the first feeding table 1 and the second feeding table 2; the crimping roller assembly 3 includes four rotating shafts 28, two of which are located on the upper side of the planar gap, and the other two rotating shafts 28 are located on the lower side of the planar gap; each rotating shaft 28 is provided with a crimping wheel 29, and the four crimping wheels 29 are arranged opposite to each other in pairs, and in each pair of opposite crimping wheels 29, one of the crimping wheels 29 is provided with a crimping groove, and the other crimping wheel 29 is provided with a crimping line that cooperates with the crimping groove; each rotating shaft 28 is provided with a number of first guide wheels 30.

[0033] When a book page is pushed from the second feed table 2 to the flat gap, it enters between the upper and lower opposing creasing rollers 29. As the rotating shaft 28 rotates, the creasing rollers 29 begin to operate, inserting the creasing lines into the creasing grooves to creasing the book page. Simultaneously, each rotating shaft 28 is also equipped with a number of first guide rollers 30. During the movement of the book page, the first guide rollers 30 guide and assist the book page in smoothly passing through the creasing roller assembly 3, ensuring that the book page can accurately and smoothly complete the creasing process and continue to move toward the first feed table 1.

[0034] The crimping rollers 29, each with a pair of opposing crimping grooves and lines, provide precise and uniform crimping for the pages. The close fit between the lines and grooves ensures the depth and clarity of the crimping, laying the foundation for the subsequent lamination of the pages to the book block. Furthermore, several first guide wheels 30 guide and support the pages as they pass through the crimping roller assembly 3, reducing friction and resistance during movement, preventing page bulges, and ensuring stability and accuracy in the crimping process. In some embodiments, the two rotating shafts 28 located on the upper side of the plane gap are respectively connected to the first gear 31 and the second gear 32, and the two rotating shafts 28 located on the lower side of the plane gap are respectively connected to the tenth sprocket 33 and the eleventh sprocket 34; the twelfth sprocket 35 and the third gear 36 are coaxially connected to the frame body; the twelfth sprocket 35 is connected to the tenth sprocket 33 and the eleventh sprocket 34 through the fourth chain 37, and the third gear 36 is meshed with the first gear 31 and the second gear 32, respectively; the eleventh sprocket 34 is connected to the coaxially rotating second intermediate sprocket 42, and the second intermediate sprocket 42 is connected to the fourth sprocket 16 through the fifth chain 38.

[0035] The power transmission path is as follows: On the one hand, the twelfth sprocket 35, the tenth sprocket 33, and the eleventh sprocket 34 are connected by the fourth chain 37. When power is transmitted to the eleventh sprocket 34, the fourth chain 37 drives the twelfth sprocket 35 and the tenth sprocket 33 to rotate, thereby driving the two rotating shafts 28 below the plane gap to rotate. On the other hand, the third gear 36 meshes with the first gear 31 and the second gear 32 respectively, causing the two rotating shafts 28 above the plane gap to rotate synchronously, ultimately achieving the four rotating shafts 28 driving the line pressing wheel 29 to press the book pages. In addition, the eleventh sprocket 34 is also connected to the fourth sprocket 16 via the second intermediate sprocket 42 and the fifth chain 38, connecting the transmission assembly of the entire line pressing roller assembly 3 to the third sprocket assembly 12, allowing the line pressing roller assembly 3 to work in conjunction with it, ensuring that the line pressing operation and the page conveying process are precisely coordinated when the book pages pass through the line pressing roller assembly 3.

[0036] In some embodiments, the first feeding table 1 is provided with two first slits 4, two parallel and synchronously moving first sprocket assemblies 5 are provided below the first feeding table 1, and two first chains 6 are respectively extended along the corresponding first slits 4; the second feeding table 2 is provided with two second slits 8, two parallel and synchronously moving second sprocket assemblies 9 are provided below the second feeding table 2, and two second chains 10 are respectively extended along the corresponding second slits 8.

[0037] When the servo motor 19 drives one of the first sprocket assemblies 5 to move, it drives the other first sprocket assembly 5 to move synchronously through the synchronization shaft, thereby causing the two first chains 6 to move forward synchronously. The first push blocks 7 on the two first chains 6 also move forward synchronously, and together push the pages. The second sprocket assembly 9 operates in the same manner.

[0038] The double chain and double push block structure can increase the force points during the book page pushing process, making the book pages more evenly stressed during the pushing process. The two sprocket assemblies are parallel and move synchronously, ensuring that the book pages will not tilt due to uneven force on both sides during the pushing process, further improving the quality of book page transportation.

[0039] In some embodiments, the first sprocket 13 is connected to a coaxially rotating second guide wheel 39, and the upper side of the second guide wheel 39 protrudes from the first feeding table 1; the fourth sprocket 16 is connected to a coaxially rotating third guide wheel 40, and the upper side of the third guide wheel 40 protrudes from the second feeding table 2.

[0040] The friction force generated by the rotation of the two guide wheels guides and assists in the transportation of book pages on the first feeding table 1 and the second feeding table 2, respectively, so that the book pages can move steadily and smoothly in the predetermined direction and path, ensuring that the book pages can accurately reach the subsequent pressing and bonding process positions.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
