Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and more specifically, to an adhesive application mechanism. Background Technology

[0002] Exercise books are indispensable stationery for students' daily studies, and their binding quality directly affects the user experience. During frequent flipping, the binding joints need sufficient adhesive strength to prevent problems such as loose pages or pages coming apart. As the core process of exercise book binding, the uniformity and accuracy of glue application directly determine the binding effect. Therefore, efficient and stable glue application technology is a key guarantee for the large-scale production of exercise books.

[0003] Currently, exercise book manufacturers mainly use two methods for applying adhesive: one is manual application using hand tools, relying on the operator's experience to control the amount of adhesive used and the application area, suitable for small-batch, multi-specification customized production; the other is batch application using simple mechanical devices. These devices typically employ a fixed adhesive application structure, using a transmission component to move the exercise books and complete the adhesive application, suitable for large-scale standardized production. Both methods are widely used in existing production scenarios, meeting basic production needs to a certain extent.

[0004] However, existing gluing technologies still have significant drawbacks and are difficult to adapt to the diverse and high-quality requirements of exercise book production. On the one hand, the paper thickness and binding edge width vary among different sizes of exercise books, making manual gluing inefficient and of inconsistent quality. The fixed structure of simple mechanical gluing devices cannot be flexibly adjusted, resulting in either excessive glue penetration into the inner pages or insufficient application affecting the bonding strength. On the other hand, the core gluing components of traditional gluing devices are cumbersome to disassemble and assemble, and subsequent cleaning and maintenance are time-consuming and labor-intensive. Furthermore, the lack of effective sealing and guiding design during glue supply can easily lead to problems such as glue leakage contaminating the equipment and exercise book misalignment causing gluing errors, which seriously affect production efficiency and product qualification rate. Therefore, we urgently need a glue application mechanism to solve the above problems. Utility Model Content

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-9 As shown, an adhesive application mechanism includes a frame 1 and a support plate 2 fixedly mounted on the frame 1.

[0026] It also includes a transmission frame 3 fixedly installed on the frame 1, with rollers 4 for conveying materials rotatably connected to the transmission frame 3, and a connecting plate 5 raised and lowered on the support plate 2 by a first driving component, with a transmission belt assembly 6 for driving the material to move fixedly connected to the connecting plate 5.

[0027] Here, the conveyor frame 3 serves as the basic support platform for material conveying. Its main body spans the working area of ​​the frame 1, forming a stable support structure. The rollers 4 are arranged in a linear array on the conveyor frame 3 along the material conveying direction. The axes of each roller 4 are parallel to each other and perpendicular to the conveying direction. Their top generatrices together form a horizontal support plane, which is used to smoothly carry and convey sheet materials such as workbooks. The rotating connection method of the rollers 4 effectively reduces the frictional resistance during the material conveying process and avoids scratches or jamming on the back of the material. At the same time, the gap arrangement of the rollers 4 also provides the necessary space redundancy for subsequent double-sided operation of the material from above and below.

[0028] Furthermore, the connecting plate 5 serves as the mounting carrier for the conveyor belt assembly 6. It achieves overall lifting and lowering through the first driving component, allowing the conveyor belt assembly 6 to flexibly adjust the distance between itself and the rollers 4 according to the material thickness and adhesive coating process requirements. The conveyor belt assembly 6 is typically made of an elastic material with a coefficient of friction. It circulates under the drive of the active roller and the driven roller. When the connecting plate 5 descends to the working position, the lower surface of the conveyor belt assembly 6 contacts the upper surface of the material, and the material is conveyed forward by means of friction. This clamping and conveying method of the upper-mounted conveyor belt combined with the lower-mounted rollers 4 not only ensures the stable transmission of conveying force, but also prevents the material from shifting due to uneven force during the adhesive coating process, thus ensuring the consistency of the adhesive coating position.

[0029] Furthermore, as a freely rotating driven component, roller 4 requires no additional power drive, has a simple and reliable structure, and when the material moves under the active traction of the conveyor belt assembly 6, roller 4 passively follows and rotates, with the linear speed between the two remaining consistent. This completely eliminates problems such as material rubbing and wrinkling caused by speed differences. This coordinated conveying mechanism provides a stable and precise material flow foundation for the entire coating mechanism.

[0030] The first driving component includes bearing seats 8 symmetrically mounted on the support plate 2. A rotating rod 9 is connected to the two sets of bearing seats 8. A first bevel gear 10 is symmetrically mounted on the rotating rod 9. A handwheel 11 for driving the rotating rod 9 to rotate is fixedly mounted at the end of the rotating rod 9. Guide rods 12 are fixedly connected to the four corners of the frame 1. Screws 13 are symmetrically rotated on the frame 1. The four corners of the connecting plate 5 are slidably connected to the corresponding guide rods 12. The connecting plate 5 is threadedly connected to the corresponding screws 13.

[0031] Here, the bearing housing 8 is symmetrically installed on the support plate 2, providing a stable double-fulcrum rotational support for the rotating rod 9, ensuring that the rotating rod 9 will not produce radial runout or bending deformation when subjected to torque. The rotating rod 9 spans the entire width of the equipment, and handwheels 11 are respectively installed at both ends. The operator can choose either side to operate according to the actual standing position, which reflects the convenient consideration of ergonomics. The symmetrically installed position of the first bevel gear 10 corresponds one-to-one with the top position of the two screws 13, ensuring the shortest transmission path and the maximum transmission efficiency.

[0032] Furthermore, the guide rods 12 fixedly connected at the four corners of the frame 1 are all smooth rod structures with precision machining and hardening treatment on their surfaces, resulting in high straightness and low friction coefficient. Linear bearings or self-lubricating bushings are correspondingly provided at the four corners of the connecting plate 5, forming a sliding fit with the guide rods 12. The distribution of the guide rods 12 forms a stable rectangular constraint frame, which strictly restricts all degrees of freedom of the connecting plate 5 except for vertical lifting, including forward and backward translation, left and right translation, and rotation around each axis. This multi-constraint mechanism ensures the absolute stability of the connecting plate 5 during the lifting process, without tilting or swaying.

[0033] Furthermore, the two symmetrically rotating screws 13 are respectively connected to the corresponding sides of the connecting plate 5 by threaded pairs. The threads of the screws 13 adopt the form of transmission threads such as trapezoidal threads or rectangular threads, which have self-locking ability. When the handwheel 11 stops rotating, the connecting plate 5 and the conveyor belt assembly 6 can be stably suspended at any height position without sliding down due to their own weight or working vibration, which fundamentally ensures the constancy and repeatability of the height parameters of the glue application operation.

[0034] The end of the guide rod 12 extends upward and is connected to the support plate 2. The end of the screw 13 passes through the support plate 2 and is fixedly installed with the second bevel gear 14. The first bevel gear 10 meshes with the second bevel gear 14. When the handwheel 11 is turned, the first bevel gear 10 on the rotating rod 9 drives the corresponding second bevel gear 14 and screw 13 to rotate. The connecting plate 5 moves along the path of the screw 13 and the guide rod 12 and forms a lifting area.

[0035] Here, the top end of the guide rod 12 extends upward to the support plate 2 and is fixedly connected to the support plate 2. This makes the entire lifting guide system and the upper drive system form a closed-loop rigid frame. The support plate 2 simultaneously supports the bearing seat 8 and the top end of the guide rod 12, and the overall rigidity and stability of the structure are significantly enhanced. The top end of the screw 13 penetrates through the support plate 2, and a bearing or bushing is provided at its penetration point to ensure that the screw 13 has good rotational alignment and low rotational resistance when rotating.

[0036] Furthermore, the first bevel gear 10 and the second bevel gear 14 form a pair of orthogonal shaft transmission pairs, which convert the rotational motion of the horizontal rotating rod 9 into the rotational motion of the vertical screw 13. The bevel gear transmission has the characteristics of precise transmission ratio, high transmission efficiency and smooth operation. By adopting a symmetrical double bevel gear pair layout, the screws 13 on both sides are driven simultaneously by a single rotating rod 9, which realizes the forced synchronous rotation of the two screws 13. This fundamentally avoids the phenomenon of tilting and jamming of the connecting plate 5 caused by the inconsistent speed of the screws 13 on both sides. It is a key technical means to ensure the stable formation of the lifting area.

[0037] Furthermore, the manual drive mode allows operators to flexibly control the lifting speed according to actual needs and sense changes in the internal resistance of the equipment in real time. Once abnormal resistance is detected, operation can be stopped to avoid damage to components caused by forced drive. The driving force of the handwheel 11 is transmitted to the connecting plate 5 through the rotating rod 9, bevel gear pair, and screw 13. This mechanical transmission chain does not rely on any electrical or hydraulic components, has extremely high inherent reliability, and has low manufacturing and maintenance costs.

[0038] Mounting plates 7 are provided on both sides of the transmission frame 3. The two sets of mounting plates 7 are connected to the frame 1 through a second driving component. The second driving component includes electric guide rails 15 symmetrically mounted on the frame 1 and connected to an external control unit. A slider 16 is symmetrically slidable on a single electric guide rail 15. A connecting frame 17 is fixedly mounted on the slider 16. A sliding groove 18 is provided on the connecting frame 17. A support frame 19 is slidably connected in the sliding groove 18. The mounting plate 7 on one side is connected to the corresponding support frame 19 to form an installation area. When the support frame 19 and the mounting plate 7 move to the corresponding position along the sliding groove 18, they are locked by bolts to form an adjustable installation area.

[0039] Here, the electric guide rail 15 is symmetrically arranged on both sides of the transfer frame 3 along the width direction of the frame 1 and is directly connected to the external control unit. It can realize automatic or semi-automatic adjustment of the position of the slider 16. The connecting frame 17 is connected to the electric guide rail 15 through the slider 16, providing the basic positioning capability for the coating part to move laterally. The electric guide rail 15 adopts the form of screw drive or synchronous belt drive, which has high positioning accuracy and repeatability, and can adapt to the width difference requirements of different batches of materials.

[0040] Furthermore, the sliding groove 18 on the connecting frame 17 and the support frame 19 constitute a second level of manual adjustment freedom. After the electric guide rail 15 completes the coarse positioning, the operator can loosen the bolts and push the support frame 19 along the guide direction of the sliding groove 18 for fine position adjustment. After adjusting to the ideal position, the bolts are tightened again. This dual-stage adjustment mechanism of electric coarse adjustment and manual fine adjustment takes into account both adjustment efficiency and adjustment accuracy. The groove wall of the sliding groove 18 forms a straight constraint on the sliding path of the support frame 19, ensuring that the position adjustment of the installation area is always carried out in the predetermined direction without any swaying.

[0041] Furthermore, the connection between the mounting plate 7 and the support frame 19 forms the mounting area, which is the foundation for the entire coating part. The mounting plate 7 on one side can be supported by one or more support frames 19, ensuring the flatness and rigidity of the mounting plate 7. When the bolts are tightened, a rigid connection is formed between the support frame 19 and the connecting frame 17. During the operation of the equipment, even if subjected to material friction and vibration generated by the rotation of the brush roller 23, the spatial position of the mounting plate 7 can remain stable, providing structural protection for the precise positioning and stable operation of the coating part.

[0042] The mounting plate 7 is detachably mounted with a coating component for applying adhesive to materials. The mounting plate 7 is L-shaped, and the short side of the mounting plate 7 is linearly and equidistantly provided with first magnetic suction holes 20. The coating component includes a rectangular frame 21. The bottom of the rectangular frame 21 is fixedly mounted with a first magnetic suction rod 22 that matches the first magnetic suction hole 20. When the first magnetic suction rod 22 is inserted into the first magnetic suction hole 20 and magnetically attracted to it, a quick-release connection area is formed. A brush roller 23 for coating materials is rotatably connected inside the rectangular frame 21.

[0043] Here, the L-shaped cross-section design of the mounting plate 7 has a dual function. Its long side is used to connect and fix with the support frame 19 to form a stable vertical mounting surface, while its short side extends horizontally to provide a flat horizontal support platform for the coated parts. The first magnetic suction holes 20 on the short side adopt a linear equidistant arrangement. This design provides a unified interface for the batch and standardized installation of multiple coated parts. Each coated part can be independently installed at any position of the first magnetic suction holes 20, and the number of coated parts can be increased or decreased according to process requirements to achieve flexible configuration.

[0044] Furthermore, the rectangular frame 21 serves as the main structure of the coated part. The first magnetic suction rod 22 fixed at its bottom and the first magnetic suction hole 20 form a quick-release connection structure. The outer diameter of the first magnetic suction rod 22 and the inner diameter of the first magnetic suction hole 20 are fitted with a small clearance to achieve accurate guidance and positioning during insertion. When the first magnetic suction rod 22 is fully inserted, the permanent magnet inside it generates a magnetic attraction force with the magnetic material or permanent magnet at the bottom of the first magnetic suction hole 20. This magnetic attraction force is sufficient to overcome the weight of the coated part itself and the slight vibration during normal operation, firmly adsorbing it onto the mounting plate 7. When disassembly is required, only a pull-out force exceeding the magnetic attraction force needs to be applied to remove the entire coated part. The entire process does not require any tools.

[0045] Furthermore, the brush roller 23 is rotatably connected inside the rectangular frame 21, with its two ends of the rotating shaft supported by bearings or bushings to ensure flexible rotation. The rectangular frame 21 provides the necessary structural protection and support for the brush roller 23, while the open surface of its frame structure allows the outer circumference of the brush roller 23 to fully contact the material. This modular coating component design integrates the brush roller 23, its mounting bearings, and the quick-release interface into an independent functional unit. Its interface is standardized and highly interchangeable, creating conditions for rapid equipment maintenance and process switching.

[0046] A sliding groove 24 is symmetrically provided on one side of the rectangular frame 21 near the conveyor frame 3. A cover plate 25 is slidably connected in the sliding groove 24. A spring 26 is provided in the sliding groove 24. The two ends of the spring 26 are connected to the inner wall of the sliding groove 24 and the cover plate 25 respectively to form an elastic support area. The bottom of the cover plate 25 and the extension platform 27 of the rectangular frame 21 form a guide area for material passage. A push plate 28 parallel to it is symmetrically installed on the conveyor belt assembly 6. When it is in the lifting area, the push plate 28 abuts against the cover plate 25 and moves along the path of the sliding groove 24, forming an adjustment state corresponding to the guide area.

[0047] Here, the opening direction of the chute 24 is perpendicular to the material's forward direction, that is, it extends along the width of the equipment. The cover plate 25 is slidably connected within the chute 24, allowing it to move in a lateral position, thereby changing the width of the guide zone formed between the bottom of the cover plate 25 and the extension platform 27. The guide zone is specifically a narrow channel, the height of which is determined by the distance between the bottom surface of the cover plate 25 and the top surface of the extension platform 27. It is used to constrain the edge passage of the material. Before the material enters the coating station, the guide zone corrects and regulates its position, ensuring that the material contacts the brush roller 23 in the correct posture and position.

[0048] Furthermore, the spring 26 is located inside the slide groove 24. Its function is to push the cover plate 25 to a preset position in the default state. When the push plate 28 does not apply external force to the cover plate 25, the elastic force of the spring 26 limits the maximum opening of the cover plate 25. This default opening corresponds to the width dimension of the standard material. When the conveyor belt assembly 6 is raised or lowered, the push plate 28 installed on it contacts the cover plate 25 and pushes it to slide along the slide groove 24. At this time, the spring 26 is compressed or stretched. The contact between the push plate 28 and the cover plate 25 is a rigid position transmission. The lifting height of the conveyor belt assembly 6 directly determines the lateral driving amount of the push plate 28 on the cover plate 25.

[0049] Furthermore, the aforementioned linkage structure achieves adaptive matching between the guide zone width and the coating height. When the connecting plate 5 drives the conveyor belt assembly 6 to rise and fall to adapt to materials of different thicknesses, the push plate 28 will simultaneously change the position of the cover plate 25, so that the lateral constraint of the guide zone forms the best matching relationship with the actual thickness of the material, preventing the material from shifting laterally or losing its guiding function due to excessive gaps when passing through. This process is fully automated and does not require additional manual adjustments by operators, greatly improving the equipment changeover efficiency.

[0050] A second magnetic suction hole 29 is provided at each of the four corners of the rectangular frame 21 on the side away from the slide 24. A placement plate 30 is provided on the rectangular frame 21. A glue plate 31 for connecting to an external glue supply device is fixedly installed on the placement plate 30. A second magnetic suction rod 32 is fixedly connected to the placement plate 30 at the corresponding second magnetic suction hole 29. When the second magnetic suction rod 32 is inserted into the second magnetic suction hole 29 and forms a magnetic attraction, the glue plate 31 contacts the brush roller 23 to form a glue supply area. Sealing gaskets 33 are fixedly installed on the placement plate 30 on both sides of the glue plate 31. When in the glue supply area, the sealing gaskets 33 abut against the inner wall of the rectangular frame 21 to form a sealing area.

[0051] Here, the placement plate 30 is magnetically assembled with the corresponding second magnetic holes 29 on the rectangular frame 21 via the second magnetic rods 32 at the four corners, forming a quick-assembly and disassembly structure for the glue supply module. The glue plate 31 is fixed on the side surface of the placement plate 30 facing the brush roller 23. Its interior has glue channels or a porous material structure, which can evenly transfer the glue supplied by the external glue supply equipment to the brush bristle surface of the brush roller 23. The four-corner magnetic engagement method ensures the precise assembly position of the placement plate 30, thereby ensuring the stability of the contact pressure and contact area between the glue plate 31 and the brush roller 23.

[0052] Furthermore, the sealing gaskets 33 are symmetrically installed on both sides of the glue plate 31, and when the glue supply area is formed, they tightly abut against the inner wall of the rectangular frame 21. This sealing fit surrounds the contact area between the glue plate 31 and the brush roller 23 in a relatively closed space, effectively preventing the glue from splashing or overflowing in all directions, maintaining the cleanliness of other areas inside the equipment. At the same time, the sealing area can slow down the evaporation rate of the solvent in the glue in the closed space, delay the skin formation on the glue surface, and maintain the good fluidity of the glue. The sealing gaskets 33 are usually made of chemically resistant elastic materials, such as silicone rubber or fluororubber, to adapt to different glue compositions.

[0053] Furthermore, the formation of the glue supply area relies on the stable maintenance of magnetic attraction, eliminating the need for an additional clamping mechanism. The glue plate 31 is a consumable accessory. After long-term use, if wear or glue blockage occurs, the entire rectangular frame 21 along with the placement plate 30 mounted on it can be removed by overcoming the magnetic attraction force. Then, a new glue plate 31 can be replaced or the entire corresponding module can be replaced. In the configuration mode of multiple coating parts, according to process requirements, the external glue supply equipment can be selectively connected to the glue plate 31 on any set of rectangular frames 21, making that station a glue supply and coating station. The other stations not connected to the glue supply equipment can be used as residual glue cleaning stations or spare stations.

[0054] In this invention, during operation, the conveyor frame 3 on the frame 1 supports the workpiece material using rollers 4. The operator rotates the handwheel 11, causing the rotating rod 9 inside the bearing seat 8 to rotate synchronously. The rotating rod 9, through the meshing of the first bevel gear 10 and the second bevel gear 14, drives the screw 13 to rotate. The connecting plate 5 moves up and down along the guide rod 12 and the screw 13, thereby adjusting the working height of the conveyor belt assembly 6 on the connecting plate 5. The operator can activate the electric guide rail 15 via an external control unit, causing the slider 16 to move laterally. The support frame 19 can slide into the sliding groove 18 of the connecting frame 17 to a suitable position and then be locked with bolts, thereby fine-tuning the installation position of the mounting plates 7 on both sides of the transmission frame 3; multiple sets of rectangular frames 21 rely on the first magnetic suction rod 22 installed at their bottom to magnetically connect and disassemble in the first magnetic suction hole 20 of the mounting plate 7, achieving quick assembly and disassembly. Each set of rectangular frames 21 is equipped with a placement plate 30. The second magnetic suction rod 32 on the placement plate 30 magnetically engages with the second magnetic suction hole 29 of the rectangular frame 21 to complete the positioning and installation. The rubber plate 31 on the placement plate 30 has dense sealing on both sides. The sealing gasket 33 is fitted to the inner wall of the rectangular frame 21 to form a sealed protection. In the initial working condition, only one of the glue plates 31 is connected to the external glue supply equipment, and the other glue plates 31 are not connected to the glue supply pipeline. The brush rollers 23 are rotatably installed inside each rectangular frame 21. The brush rollers 23 connected to the glue supply are responsible for applying glue to the workbook, and the other brush rollers 23 are used to scrape off excess glue from the surface of the material. During the lifting and lowering of the connecting plate 5, the push plate 28 on the conveyor belt assembly 6 will press against the cover plate 25 in the slide groove 24 of the rectangular frame 21, causing the cover plate 25 to slide and squeeze. The spring 26 is compressed to adaptively change the material passage guide range between the cover plate 25 and the extension platform 27. During the operation, the material is conveyed forward under the support of the roller 4 and driven by the conveyor belt assembly 6, and passes through each brush roller 23 to complete the glue application and residual glue cleaning. When any set of brush rollers 23 needs cleaning and maintenance, the external glue supply equipment can be switched and connected to other idle glue plates 31, and the rectangular frame 21 to be maintained can be magnetically picked up from the mounting plate 7 for individual cleaning. The whole process does not require the equipment to be stopped, and the coating operation can be kept running continuously.
