Description

Technical Field

[0001] This utility model relates to the field of book page processing technology, and mainly to a book page pre-pressing mechanism. Background Technology

[0002] In the printing industry, lamination of book pages not only improves product quality and durability but also increases adhesion. However, during the lamination process, uneven stress can cause pages to bend. Furthermore, shrinkage stress can occur after the glue dries, leading to page deformation. This is especially true for laminated pages that form thicker cardboard; without proper treatment, the overall curvature will be more pronounced when the pages are bound. Poor page flatness negatively impacts binding, product appearance, and user experience. Therefore, it is necessary to provide a treatment structure to address page curvature issues. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a book page pre-pressing mechanism, which aims to solve the problem of cumbersome adjustment operation of existing rubber rollers.

[0004] The technical solution of this utility model is as follows:

[0009] The conveyor belt includes a first conveyor belt and a second conveyor belt, which are arranged side by side with a gap between them, forming an open area for the pusher block to pass through.

[0010] This application uses a conveyor belt to transport book pages, with a pressure roller assembly positioned above the conveyor belt. As the book pages pass through, the pressure roller assembly applies pressure to flatten them. By setting the conveyor belt as a first conveyor belt and a second conveyor belt with a gap between them for the pusher block to pass through, the book pages are pushed into the pressure area. The pressure applied by the pressure roller assembly ensures the flattening effect of the book pages and achieves effective pre-pressure on the pages.

[0017] Furthermore, the pressure roller assembly also includes:

[0018] The second pressure roller is disposed at the end of the conveyor belt;

[0019] A fixed roller is arranged side by side below the second pressure roller, and a gap is formed between the fixed roller and the second pressure roller for the pages to abut and pass through.

[0020] This application uses a second pressure roller at the end of the conveyor belt to apply pressure to the pages again, thereby stabilizing and ensuring the overall flatness of the pages.

[0027] The U-shaped guide frame is fixedly connected to the bottom end of the first sliding rod, and the connecting frame is rotatably connected to the first pressure roller through both ends of the U-shaped guide frame;

[0028] The first sliding rod is fitted with a first spring, which is disposed between the suspension and the U-shaped guide. The first pressure roller slides upward to compress the first spring.

[0029] Furthermore, the pressure roller assembly also includes:

[0031] The transmission assembly, according to the transmission direction, is disposed between the fixed roller and the second pressure roller, the fixed roller and the second pressure roller rotate in opposite directions, and the fixed roller and the second pressure roller drive the book pages away from the conveyor belt by rotation.

[0032] Furthermore, the pressure roller assembly also includes:

[0033] Second guide rail;

[0034] The second slider is slidably connected to the second guide rail, slides up and down along the second guide rail, and is rotatably connected to the second pressure roller.

[0036] Furthermore, the fixed roller is provided with a first synchronous gear that rotates coaxially, and the second pressure roller is provided with a second synchronous gear that rotates coaxially.

[0037] The transmission assembly includes:

[0038] A first transmission gear, which meshes with the first synchronizing gear;

[0039] The second transmission gear meshes with the first transmission gear and the second synchronizing gear;

[0040] A first connecting rod is provided with a first connecting hole and a second connecting hole.

[0044] An inclined rod is disposed above the working surface of the conveyor belt, and the inclination direction of the inclined rod corresponds to the conveying direction of the conveyor belt.

[0045] Beneficial effects: This application uses a conveyor belt to transport book pages, with a pressure roller assembly positioned above the conveyor belt.

[0051] This utility model provides a page pre-pressing mechanism. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description of this utility model. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit this utility model.

[0052] Reference Figures 1-4 This application provides a page pre-pressing mechanism, comprising:

[0053] Conveyor belt 100, drive belt 100 is used to transport book pages;

[0054] Pressure roller assembly 200 is disposed above the conveyor belt 100 and is used to apply pressure to the pages of the book.

[0055] Push block 300 moves along the conveying direction of conveyor belt 100 and is used to push the pages of the book.

[0056] The conveyor belt 100 includes a first conveyor belt 110 and a second conveyor belt 120. The first conveyor belt 110 and the second conveyor belt 120 are arranged side by side with a gap between them, and a gap area 130 is formed between the first conveyor belt 110 and the second conveyor belt 120 for the pusher block 300 to pass through.

[0057] The conveyor belt 100 can naturally be equipped with a corresponding drive device for driving. The first conveyor belt 110 and the second conveyor belt 120 can both be driven by the same drive device and can maintain the same conveying speed, which is beneficial to the stable transport of book pages.

[0058] Both the pressure roller assembly 200 and the conveyor belt 100 can be mounted on the frame.

[0059] In this application, the book pages are transported by placing them on the working surface of the conveyor belt 100. When the book pages are transported to the pressure roller assembly 200, the pressure roller assembly 200 can apply pressure to the book pages to restore the curved pages to flatness.

[0060] In situations where the pressure applied by the pressure roller assembly 200 is high enough to ensure the required flatness, or when the book pages are made of thick cardboard, the conveying effect of the conveyor belt 100 is not significant, and the book pages are easily "stuck" in front of the pressure roller assembly 200. This application addresses this by setting up a first conveyor belt 110 and a second conveyor belt 120 to transport the book pages. A gap area 130 is formed between the first conveyor belt 110 and the second conveyor belt 120 for the pusher block 300 to pass through, ensuring that the pusher block 300 can push the book pages into the pressure area. Furthermore, when the pages are conveyed to the pressure roller assembly 200, since the middle of the pages generally passes through the gap area 130, the pressure roller assembly 200 applies downward pressure, so the force on the middle of the pages is lower than that on the sides. The pressure roller assembly 200 can fix the sides of the pages, forming "end constraint". When the sides of the pages are fixed, the constraint force at both ends will force the middle of the pages to extend to both sides. At the same time, the internal stress generated by the initial bending in the middle is transformed into lateral tension in this process, and the degree of bending in the middle will be significantly reduced, which is beneficial to flattening the pages and can also flexibly cope with the bending of the pages.

[0061] The pre-pressing mechanism for the book pages can be equipped with a sprocket and a chain, and the pusher block 300 is fixed on the chain. The sprocket is driven to rotate by a drive device, and the pusher block 300 is moved to push the book pages.

[0062] Reference Figure 1 In one specific embodiment of this application, a pallet 140 is provided below the working surface of both the first conveyor belt 110 and the second conveyor belt 120, and the pallet 140 abuts against the bottom surface of the working surface of the conveyor belt 100 through the pressure roller assembly 200.

[0063] The tray 140 does not penetrate the gap area 130, and the tray 140 is arranged on the same plane.

[0064] The pallet 140 can be mounted on the frame.

[0065] In this application, the conveyor belt 100 is mainly used for transporting book pages. It is generally a flexible flat belt that can rotate around the rollers. If the pressure roller assembly 200 applies a large pressure, the structural limitations of the conveyor belt 100 make it difficult to provide a corresponding reaction force to ensure the flattening effect of the book pages, and it can also easily affect the transmission efficiency of the conveyor belt. In this application, a support plate 140 is set below the working surface of the conveyor belt 100. As a rigid structure, it can abut against the bottom surface of the working surface of the conveyor belt 100 through the pressure roller assembly 200, ensuring sufficient reaction force and helping to ensure the flattening effect of the book pages.

[0066] Reference Figure 1 In one specific embodiment of this application, the pressure roller assembly 200 includes:

[0067] The first pressure roller 210 is disposed above the working surface of the conveyor belt 100, and the first pressure roller 210 corresponds to the first conveyor belt 110 and the second conveyor belt 120.

[0068] The first pressure roller 210 corresponds to the first conveyor belt 110 and the second conveyor belt 120, indicating that the first pressure roller 210 can simultaneously apply pressure to the pages on the first conveyor belt 110 and the second conveyor belt 120, and the roller portion of the first pressure roller 210 does not cross the gap area 130.

[0069] In this application, since a gap region 130 is provided between the first conveyor belt 110 and the second conveyor belt 120, and the pallet 140 does not penetrate the gap region 130, if a first pressure roller 210 with an extension length spanning the gap region 130 is provided, it is easy to press a portion of the book page into the gap region 130 during pressure application, which may lead to unnecessary bending. This application, by providing a first pressure roller 210 corresponding to the first conveyor belt 110 and the second conveyor belt 120, helps to ensure the pressure-flattening effect of the book page.

[0070] Specifically, the length of the first pressure roller 210 can be set according to the width of the cardboard or the width of the pallet 140 to ensure that pressure can be applied evenly to both sides of the book page.

[0071] Reference Figure 3 In one specific embodiment of this application, the pressure roller assembly 200 further includes:

[0072] The second pressure roller 220 is disposed at the end of the conveyor belt 100;

[0073] A fixed roller 230 is arranged side by side below the second pressure roller 220, and a gap is formed between the fixed roller 230 and the second pressure roller 220 for the pages to abut and pass through.

[0074] The fixed roller 230 can be located below the second pressure roller 220, and the weight of the pressure roller can provide part of the pressure that needs to be applied.

[0075] In this application, by setting a second pressure roller 220 at the end of the conveyor belt 100, the book pages are flattened by the pressure applied by the first pressure roller 210, and then run to the end of the conveyor belt 100 and enter the gap between the second pressure roller 220 and the fixed roller 230. The second pressure roller 220 applies pressure to the entire book page, which helps to strengthen and stabilize the flatness of the book page.

[0076] Reference Figure 1 In one specific embodiment of this application, the pressure roller assembly 200 further includes:

[0077] First guide rail 211;

[0078] The first slider 212 is slidably connected to the first guide rail 211, and the first slider 212 slides left and right along the first guide rail 211.

[0079] The first slider 212 is provided with a suspension 213 that slides up and down along the first slider 212, and a connecting frame 214 that slides up and down along the suspension 213 is provided on the suspension 213. The connecting frame 214 is rotatably connected to the first pressure roller 210.

[0080] The first guide rail 211 can be mounted on the frame.

[0081] In this application, by setting the first slider 212 to slide left and right along the first guide rail 211, the suspension 213 can be controlled to slide left and right. The suspension 213 is provided with a connecting frame 214 that is rotatably connected to the first pressure roller 210, so that the first pressure roller 210 can be adjusted up and down and left and right to accurately adjust the position of the first pressure roller 210 and ensure that it corresponds to the page that needs to be pre-pressed.

[0082] Specifically, a guide rail can be set on the first slider 212, and a slider that is slidably connected to the guide rail can be set on the suspension 213. The vertical position of the suspension 213 can be adjusted or fixed by setting screws and nuts.

[0083] Reference Figure 1 In one specific embodiment of this application, the connecting frame 214 includes:

[0084] The first sliding rod 2141 is slidably connected to the suspension 213;

[0085] U-shaped guide frame 2142 is fixedly connected to the bottom end of the first sliding rod 2141, and the connecting frame 214 is rotatably connected to the first pressure roller 210 through both ends of the U-shaped guide frame 2142.

[0086] The first sliding rod 2141 is fitted with a first spring 2143, which is located between the suspension 213 and the U-shaped guide 2142. The first pressure roller 210 slides upward to compress the first spring 2143.

[0087] In this application, by mounting a first spring 2143 on the first sliding rod 2141, when the book page passes the first pressure roller 210, the thickness of the book page forces the first pressure roller 210 to move upward, driving the U-shaped guide 2142 fixedly connected to the first pressure roller 210 to also move upward. The first sliding rod 2141 slides upward towards the suspension 213. During this process, the U-shaped guide 2142 and the suspension 213 compress the first spring 2143, accumulating elastic potential energy, thereby causing the first spring 2143 to generate elastic force and continuously apply pressure to the book page, ensuring the pressure effect of the first pressure roller 210. By setting the first spring 2143 to apply pressure, the overall transition of the book page during the pressure application process is smoother, which helps to reduce the movement of the book page on the conveyor belt and helps to ensure the pressure effect.

[0088] Alternatively, by fixing the height of the first sliding rod 2141, the first spring 2143 can be kept in a compressed state so that the first pressure roller 210 abuts against the conveyor belt 100. This ensures that the book pages can enter and pass between the first pressure roller 210 and the conveyor belt 100, which is beneficial for the book pages to be flattened by the required preset pressure when passing through.

[0089] One end of the first sliding rod 2141 is fixedly connected to the U-shaped guide frame 2142, and the other end can be equipped with a limiting nut. A corresponding thread is provided on the first sliding rod 2141. The height of the first pressure roller 210 is controlled by rotating the limiting nut to meet the required production needs. The pressure applied by the first pressure roller 210 can be controlled by adjusting the elastic coefficient, initial compression degree, and page thickness of the first spring 2143, which can be set according to product requirements.

[0090] Reference Figure 2 and Figure 3 In one specific embodiment of this application, the pressure roller assembly 200 further includes:

[0091] The first driving device is used to drive the fixed roller 230 and the second pressure roller 220 to rotate.

[0092] The transmission assembly 240 is disposed between the fixed roller 230 and the second pressure roller 220 according to the transmission direction. The fixed roller 230 and the second pressure roller 220 rotate in opposite directions. The fixed roller 230 and the second pressure roller 220 drive the book pages away from the conveyor belt 100 by rotating.

[0093] In this application, the pages are conveyed by the friction of the conveyor belt 100, while the second pressure roller 220 needs to apply pressure to the pages. The gap between the second pressure roller 220 and the fixed roller 230 is small, which can easily cause resistance to the pages that need to enter, resulting in jamming. This application solves this problem by setting the fixed roller 230 and the second pressure roller 220 to be rotatable. By setting their rotation directions to be opposite and corresponding to the conveying direction of the pages, when the pages begin to leave the conveyor belt 100 and enter the gap between the second pressure roller 220 and the fixed roller 230, the second pressure roller 220 can apply pressure by contact while the two rollers clamp the pages and drive them away from the conveyor belt 100 through their rotation, so that subsequent processes can proceed.

[0094] Reference Figure 2 and Figure 3 In one specific embodiment of this application, the pressure roller assembly 200 further includes:

[0095] Second guide rail 215;

[0096] The second slider 216 is slidably connected to the second guide rail 215. The second slider 216 slides up and down along the second guide rail 215. The second slider 216 is rotatably connected to the second pressure roller 220.

[0097] A second sliding rod 217 is fixedly connected above the second slider 216. A second spring 2171 is sleeved on the second sliding rod 217. The second pressure roller 220 slides upward to compress the second spring 2171.

[0098] In this application, by setting a second spring 2171, when the book page enters the gap between the second pressure roller 220 and the fixed roller 230, the second pressure roller 220 is lifted upward, and the slider rotatably connected to it also moves upward, compressing the second spring 2171 sleeved on the second sliding rod 217. The pressure generated by the second spring 2171 is used as the pressure applied to the book page.

[0099] The second guide rail 215 can be mounted on the frame, and a top plate is provided above the second pressure roller 220. The second sliding rod 217 can move up and down through the top plate. The height of the second pressure roller 220 can be controlled by setting a thread similar to that of the first sliding rod 2141 and a corresponding limiting nut on the second sliding rod 217. The pressure control of the second pressure roller 220 is also similar to that of the first pressure roller 210.

[0100] Alternatively, the height of the second sliding rod 217 can be fixed to keep the sleeved second spring 2171 in a compressed state so that the second pressure roller 220 abuts against the fixed roller 230.

[0101] The second pressure roller 220 can also be kept under a certain pressure by the second spring 2171 and continuously abut against the fixed roller 230. This ensures that the book pages can enter and pass between the second pressure roller 220 and the fixed roller 230. This is beneficial for the book pages to be pressed flat by the required preset pressure when passing through, ensuring the overall pre-pressing and flattening effect of the book pages.

[0102] Reference Figure 2 and Figure 3 In one specific embodiment of this application, a first synchronous gear 231 that rotates coaxially is provided on the fixed roller 230, and a second synchronous gear 221 that rotates coaxially is provided on the second pressure roller 220;

[0103] Transmission assembly 240 includes:

[0104] The first transmission gear 241 meshes with the first synchronizing gear 231;

[0105] The second transmission gear 242 meshes with the first transmission gear 241 and the second synchronous gear 221.

[0106] The first connecting rod 243 is provided with a first connecting hole 2431 and a second connecting hole 2432. The first connecting hole 2431 is coaxially connected to the second transmission gear 242 through a bearing, and the second connecting hole 2432 is coaxially connected to the second pressure roller 220 through a bearing.

[0107] In this application, by sequentially meshing the first synchronous gear 231, the first transmission gear 241, the second transmission gear 242 of the fixed roller 230 and the second synchronous gear 221 of the second pressure roller 220, when the fixed roller 230 rotates, the second pressure roller 220 rotates simultaneously and in the opposite direction to the fixed roller 230, ensuring that the pages can pass smoothly through the gap between the fixed roller 230 and the second pressure roller 220.

[0108] Specifically, the first connecting hole 2431 of the first connecting rod 243 is coaxially connected to the second transmission gear 242 through a bearing, and the second connecting hole 2432 is coaxially connected to the second pressure roller 220 through a bearing. With this arrangement, when the second slider 216 moves, the first connecting rod 243 can rotate about the first connecting hole 2431 as the axis.

[0109] The second pressure roller 220 in this application is also rotatably connected to the second slider 216. This application connects the second pressure roller 220 by setting a first connecting rod 243 between the second transmission gear 242 and the second pressure roller 220, so as to control the sliding range of the second slider 216 within a certain stroke. This ensures that when the second slider 216 slides within this range, the second transmission gear 242 meshes with the fixed gear of the second pressure roller 220, so as to maintain the transmission of the second transmission gear 242 to the second pressure roller 220.

[0110] The first driving device can be a motor, which drives the fixed roller 230 to rotate by meshing with the drive gear of the motor and the roller shaft gear of the fixed roller 230 via a synchronous belt. Specifically, the transmission assembly 240 may also include a second connecting rod, which has connecting holes that are coaxially connected to the fixed roller 230, the first transmission gear 241 and the second transmission gear 242 via bearings to ensure transmission.

[0111] Reference Figure 1 and Figure 4 In one specific embodiment of this application, the page pre-pressing mechanism further includes a limiting component 400;

[0112] Limiting component 400 includes:

[0113] Side plate 410 is disposed on the working surface of conveyor belt 100 and on both sides of the page;

[0114] An inclined bar 420 is positioned above the working surface of the conveyor belt 100, and the inclination direction of the inclined bar 420 corresponds to the conveying direction of the conveyor belt 100.

[0115] The inclination direction of the inclined bar 420 corresponds to the conveying direction of the conveyor belt 100, with the inclined bar 420 tilting downwards towards the end of the conveyor belt 100. This application includes a first pressure roller 210 and a second pressure roller 220, forming two corresponding pressure areas. Depending on the conveying direction of the conveyor belt 100, the inclined bars 420 are positioned before the pressure areas, with their number corresponding to the pressure areas.

[0116] In this application, by providing side plates 410 on both sides of the book pages, it is possible to prevent the book pages from deviating from the predetermined pressure roller area during the conveyor belt 100 transport process. By providing diagonal bars 420, it is possible to prevent the book pages from stacking into the pressure roller area, which helps to ensure the pressure effect on the book pages. It also helps to prevent material jamming on the conveyor belt and affecting production.

[0117] Specifically, since the pressure area on the conveyor belt 100 involves the pressure roller assembly 200, and the pages are pressed by the first pressure roller 210 when passing through the pressure area, making them less prone to deviation, the side plate 410 can be respectively set in front of and behind the pressure area on the conveyor belt 100 and connected by a U-shaped connecting plate. The inlet of the side plate 410 can be set in a trumpet shape to facilitate the pages entering the channel formed by the limiting assembly 400.

[0118] In the specific implementation of the page pre-pressing mechanism provided in this application: by adjusting the sliding position of the first slider 212 on the first guide rail 211, the first pressure roller 210 is ensured to be in a suitable area; by adjusting the up-and-down sliding position of the suspension 213 on the first slider 212, the first pressure roller 210 is controlled to be at a suitable height; by adjusting the height of the second sliding rod 217, the height of the second slider 216 is controlled, ensuring that the gap between the second pressure roller 220 rotatably connected thereon and the fixed roller 230 is at a suitable height.

[0119] After preparation, the conveyor belt 100 and the first drive device are started. The book pages are placed on the conveyor belt 100. After passing through the flared entrance of the side plate 410, the book pages enter the channel formed by the limiting component 400. The inclined rod 420 in the limiting component 400 keeps the book pages passing one by one and prevents them from stacking. The book pages are pushed to the bottom of the first pressure roller 210 by the pusher block 300. Under the influence of the thickness of the book pages, the first pressure roller 210 moves upward. The first sliding rod 2141 moves upward and compresses the first spring 2143 through the U-shaped guide frame 2142. The first pressure roller 210 applies pressure to the book pages through the elastic force of the first spring 2143 and the reaction force of the support plate 140. Since the conveyor belt 100 is provided with a gap area 130, the first pressure roller 210 mainly applies pressure to the two sides of the book pages to flatten them.

[0120] After the book page leaves the pressure area on the conveyor belt 100, it continues to reach the end of the conveyor belt 100 through the channel formed by the limiting component 400. When the book page contacts the second pressure roller 220, the fixed roller 230 and the second pressure roller 220 are driven to rotate by the first driving device. The first synchronous gear 231, the first transmission gear 241, and the second transmission gear 242 of the fixed roller 230 and the second synchronous gear 221 of the second pressure roller 220 mesh in sequence, ensuring that the rotation directions of the fixed roller 230 and the second pressure roller 220 are opposite. The book page can be clamped by the second pressure roller 220 and the fixed roller 230 through the gap between them and move away from the conveyor belt 100. During this process, pressure is applied to the pages. The thickness of the pages forces the second pressure roller 220 to move the second slider 216 upward. As the second slider 216 moves upward, the second connecting hole 2432 on the first connecting rod 243 rotates around the first connecting hole 2431, ensuring that the second transmission gear 242 and the synchronous gear of the second pressure roller 220 remain engaged during the movement of the second slider 216, thus maintaining the transmission. A second sliding rod 217 is fixedly connected to the second slider 216. During the upward movement, the second spring 2171 sleeved on the second sliding rod 217 is compressed. The second pressure roller 220 applies pressure to the entire page and flattens it through the elastic force of the second spring 2171 and the reaction force of the fixed roller 230, stabilizing the flatness of the page and completing the pre-pressing process.

[0121] The page pre-compression mechanism provided in this application is simple and efficient in operation, and the pressure effect is easily adjustable with high precision, making it adaptable to different product requirements. This design effectively pre-compresses and flattens the pages, facilitating binding and ensuring product performance.

[0122] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of this utility model.
