The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] The following is for reference. Figures 1-6 A glue applicator for perfect binding according to an embodiment of the present invention is described.

[0040] like Figures 1-6 As shown, the perfect binding glue applicator includes a frame 100 and a glue tank 110 mounted on the frame 100. As part of the glue application process in the book production line, the books to be glued on the transport line enter the glue application area from one side of the glue tank 110 and complete the perfect binding process when they come out from the other side of the glue tank 110.

[0041] The glue coating area of ​​the glue tank 110 includes an adaptive glue coating mechanism 200, which can transfer the glue in the glue tank 110 to the glue-to-book area to achieve glue transfer. Different books have different requirements for glue coating thickness and glue coating method. In order to meet the glue coating requirements of different books, at least one set of adaptive glue coating mechanism 200 is provided in the glue tank 110.

[0042] Specifically, the adaptive gluing mechanism 200 includes a gluing roller 210 rotatably connected to the glue tank 110, a thickness adjustment component 220 disposed on one side of the gluing roller 210, and an adaptive drive component 230 for driving the thickness adjustment component. The gluing roller 210 rotates continuously within the glue tank 110. When the glue enters the roller surface of the gluing roller 210, the glue adheres to the roller surface of the gluing roller 210 and rotates with the gluing roller 210. When the glue passes through the thickness adjustment component 220, the thickness adjustment component 220 can scrape off the glue on the roller surface of the gluing roller 210 to achieve a set thickness of glue on the roller surface. The gluing roller 210 then contacts the book to transfer the glue onto the book, completing the perfect binding process.

[0043] The existing glue coating equipment on the production line only has a fixed coating thickness. When different coating thicknesses are needed, the machine must be stopped, and staff must manually adjust the equipment to the required thickness. This adjustment process is cumbersome and time-consuming, and the production line is shut down, impacting production efficiency. Furthermore, if the coating thickness is not adjusted correctly, the above steps must be repeated, causing significant losses to production and operations.

[0044] In this embodiment, the adaptive drive component 230 is connected to the thickness adjustment unit, enabling real-time adjustment of the thickness adjustment unit's position during production line operation to change the adhesive thickness of the coating roller 210. The high-precision control of the adaptive drive component 230 allows for adjustment of the adhesive thickness or the implementation of different coating methods, such as dot-matrix coating, strip-interval coating, and coating with varying adhesive thickness areas. Existing coating equipment requires additional equipment and manual calibration to achieve these effects, increasing the production line's footprint and production costs, which is detrimental to the modification of existing production lines.

[0045] The perfect binding glue applicator includes a control component (not shown in the attached drawings) and a glue application drive mechanism. The control component is electrically connected to the adaptive drive component 230 and is used to control the operation of the adaptive drive component 230. The control component automatically adjusts the thickness adjustment component 220; operators only need to input parameters in the background to change the working angle of the thickness adjustment component 220 in real time, thereby achieving any glue thickness. The glue application drive mechanism is located in the glue tank 110 and is connected to the glue application roller 210. The glue application drive mechanism drives the glue application roller 210 to apply glue to the books on the transport line.

[0046] The thickness adjustment component 220 includes an adjustment roller 221 rotatably connected within the adhesive tank 110. An adhesive scraper 222 is positioned on the adjustment roller 221 corresponding to the position of the coating roller 210, and rotates synchronously with the adjustment roller 221. The adjustment roller 221 is connected to an adaptive drive component 230 via a swinging part 223. The adaptive drive component 230 adjusts the scraping angle of the adhesive scraper 222 in real time. The adhesive scraper 222 has an inclined scraping surface on the side closest to the coating roller 210, which is used to push and scrape the adhesive from the surface of the coating roller 210.

[0047] Specifically, the adjusting roller 221 and the colloid doctor blade 222 rotate synchronously. When the angle of the adjusting roller 221 is changed, the distance between the colloid doctor blade 222 and the coating roller 210 is adjusted accordingly, thereby changing the colloid thickness on the surface of the coating roller 210. The swing part 223 is connected to the adjusting roller 221, and the adaptive drive assembly 230 can change the rotation angle of the adjusting roller 221, thereby realizing real-time adjustment of the colloid doctor blade 222.

[0048] In some embodiments of the present invention, such as Figures 1-5 As shown, the adaptive component includes a pitch motor 231 and a lead screw module 232. The pitch motor 231 is electrically connected to the control, and the lead screw module 232 is drive-connected to the pitch motor 231. The lead screw module 232 is provided with a slidingly connected adjusting slider 233, and the adjusting slider 233 is connected to the swing part 223.

[0049] When the adjusting slider 233 moves, the swinging part 223 drives the colloid scraper 222 to swing at a certain angle. Specifically, the pitch motor 231 can be a stepper motor or a servo motor, both of which have the advantage of high precision and can accurately control the swing angle of the colloid scraper 222. The pitch motor 231 is connected to the lead screw of the lead screw module 232 through a belt, chain, or coupling, thereby driving the lead screw to rotate and causing the adjusting slider 233 to move along the lead screw direction. The adjusting slider 233 is connected to the swinging part 223. When the adjusting slider 233 slides, the swinging part 223 follows to adjust the angle of the adjusting roller 221. The lead screw module 232 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0050] In other embodiments, the adjustable pitch motor 231 can also be directly connected to the lead screw of the lead screw module 232 for transmission.

[0051] In a further embodiment, such as Figures 1-5 As shown, the swing part 223 is provided with a swing block 223a at one end near the adjusting slider 233, and the adjusting slider 233 is provided with a swing groove seat 233a. The swing block 223a moves in the swing groove seat 233a. When the adjusting slider 233 slides, the swing groove seat 233a drives the swing block 223a to swing at a certain angle.

[0052] Specifically, the swinging part 223 has a rod-shaped structure. A protruding swing block 223a is provided at one end of the swinging part 223 near the swinging groove seat 233a. The swing block 223a moves within the swinging groove seat 233a, allowing the adjusting slider 233 to drive the swinging part 223 to swing. When the adjusting slider 233 moves, the swinging groove seat 233a moves horizontally, causing the swing block 223a to move horizontally. Since the swing block 223a is connected to the swinging part 223, it moves horizontally while simultaneously displacing vertically along the swinging groove seat 233a. The swinging part 223 swings around the adjusting roller 221, thus preventing the swinging part 223 from getting stuck. Throughout the adjustment process, the movement path of the swing block 223a is an arc centered on the adjusting roller 221.

[0053] In a further embodiment, such as Figures 1-5 As shown, one end of the swing part 223 is connected to the adjusting roller 221, and the other end is rotatably connected to the swing block 223a. The diameter of the swing block 223a is equal to the groove width of the swing groove seat 233a.

[0054] Specifically, in order to improve the adjustment accuracy of the adaptive glue application mechanism 200, the width of the swing block 223a is equal to the width of the swing groove seat 233a, reducing the play in the movement of the swing block 223a and the inner wall of the swing groove seat 233a, thereby making the transmission efficiency between the adaptive drive component 230 and the thickness adjustment component 220 higher.

[0055] In some embodiments of the present invention, such as Figures 1-3 As shown, the system includes two sets of adaptive gluing mechanisms 200, which are located at the same horizontal level. Specifically, in this embodiment, the glue tank 110 is equipped with two sets of adaptive gluing mechanisms 200, and the tangents of the top roller surfaces of the gluing rollers 210 of the two sets of adaptive gluing mechanisms 200 are located on the same plane, ensuring that the books on the transport line obtain stable glued quality in the gluing area.

[0056] In some embodiments of the present invention, such as Figure 6 As shown, the adhesive application drive mechanism includes a drive motor (not shown in the figure), a driven gear 320, and a driving gear 310. The driven gear 320 is connected to the adhesive application roller 210. The driven gears 320 of the two adhesive application rollers 210 are connected by a transmission gear 330, which enables the two adhesive application rollers 210 to rotate in the same direction. The driving gear 310 is connected to either adhesive application roller 210, and the drive motor drives the driving gear 310 to simultaneously drive the two adhesive application rollers 210 to rotate in the same direction.

[0057] Specifically, the glue application drive mechanism can simultaneously drive two sets of glue application rollers 210 to rotate through the transmission combination of driven gear 320, driving gear 310 and transmission gear 330. The two glue application rollers 210 rotate synchronously, resulting in more stable glue binding quality.

[0058] Using a glue-driving mechanism to simultaneously drive two glue-driving rollers 210 is not the only implementation method. In some other embodiments, two sets of glue-driving mechanisms can be directly connected to the two glue-driving rollers 210 respectively, according to actual production needs. The two glue-driving mechanisms can rotate synchronously or differentially to achieve different rotation conditions of the glue-driving rollers 210.

[0059] In some embodiments of the present invention, such as Figures 1-3 As shown, the control component is electrically connected to the adaptive drive component 230 of the two adaptive glue application mechanisms 200 respectively, and the glue scraper 222 of the two adaptive glue application mechanisms 200 can be adjusted independently.

[0060] Specifically, the operator controls the adaptive drive component 230 via a control unit, enabling the two thickness adjustment components 220 to operate independently, allowing the two coating rollers 210 to be set to different coating thicknesses. Adhesive thickness adjustment can be performed remotely without stopping the production line, significantly reducing the adhesive thickness adjustment time, ensuring continuous production without downtime, and improving production efficiency.

[0061] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a guide mechanism 400 is rotatably connected above one side of the adhesive tank 110 and located on one side of the adhesive roller 210. The guide mechanism 400 is connected to the driven gear 320. Specifically, the guide mechanism 400 is mainly used for auxiliary conveying of books on the transport line. The guide mechanism 400 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0062] In some embodiments of the present invention, such as Figures 1-5 As shown, the colloid scraper 222 is detachably connected to the adjusting roller 221. Specifically, the colloid scraper 222 is connected to the mounting surface of the adjusting roller 221 by screws, which facilitates the replacement of the colloid scraper 222 later.

[0063] In some embodiments of the present invention, such as Figures 2-4 As shown, the blade width of the glue scraper 222 is not less than the roller width of the glue coating roller 210. This ensures that the glue thickness on the roller surface of the glue coating roller 210 is consistent, thus improving the glue coating quality in the glue binding process.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
