Description

Technical Field

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

[0002] Currently, bound books are generally glued using glue rollers on a glue-coating machine, applying glue to the corresponding positions. However, due to the extremely stringent requirements for precision in graphic design and layout of modern books, even higher standards have been placed on the accuracy of glue application on the rollers.

[0003] Currently, traditional gluing machines, while featuring pre-defined gluing zones on the rollers for precise gluing, rely on a method of adjusting the roller's position by slowly rotating it little by little using a push-button control motor. This method is inaccurate, cumbersome, and often requires repeated adjustments by the operator. Furthermore, frequent starting and stopping of the motor for adjustments negatively impacts the overall gluing accuracy and lifespan of the machine over time. Therefore, the roller adjustment mechanism in current gluing machines has limitations that affect the desired gluing effect. Consequently, existing technology requires improvement and development. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a gluing machine that aims to solve the problem of cumbersome adjustment operation of existing glue rollers.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model provides a gluing machine, comprising:

[0007] Rubber rollers are used to apply adhesive to substrates.

[0008] A drive motor and a gluing machine phase adjustment mechanism, wherein the drive motor drives the glue roller to rotate and apply glue through the gluing machine phase adjustment mechanism;

[0009] The phase adjustment mechanism of the glue applicator includes a motor drive section, a manual adjustment section, and a glue roller drive section according to the direction of the transmission stroke. The manual adjustment section includes an adjustment drive shaft for adjusting the transmission stroke of the glue roller drive section, which affects the phase angle of the glue roller. The adjustment drive shaft is detachably connected to an adjustment handwheel.

[0010] Compared to traditional equipment whose lifespan is shortened due to frequent motor operation, this design utilizes a manual adjustment mechanism. This mechanism includes a phase adjustment section comprising a motor drive section, a manual adjustment section, and a rubber roller transmission section. A detachable handwheel in the manual adjustment section allows operators to easily adjust the roller manually. By influencing the transmission stroke of the rubber roller transmission section, the rotation angle of the rubber roller is altered, achieving precise control over the application position and ensuring the application area on the roller is positioned correctly. This effectively reduces the number of motor start-stop cycles during traditional adjustments, significantly extending the equipment's lifespan and operational stability. This improvement not only enhances application accuracy, meeting the demands of high-precision application, but also increases operational flexibility and convenience, reduces equipment wear and tear, thereby improving production efficiency and product quality.

[0011] Furthermore, the motor drive section includes:

[0012] A first drive shaft has two gears coaxially arranged on it. One gear meshes with the drive gear of the drive motor, and the other gear meshes with a first synchronous belt.

[0013] The adjusting transmission shaft is coaxially equipped with two gears, one of which meshes with the first synchronous belt, and the other gear meshes with the second synchronous belt;

[0014] The rubber roller drive section includes:

[0015] The third drive shaft has two gears coaxially arranged. One gear meshes with the second synchronous belt, and the other gear meshes with the third synchronous belt. The third synchronous belt meshes with the roller shaft gear of the rubber roller.

[0016] In this invention, by adding an adjusting drive shaft between the motor drive section and the rubber roller transmission section, the rotation angle of the rubber roller can be controlled more precisely. The adjusting drive shaft allows for fine-tuning of the transmission stroke, thereby achieving precise control of the rubber roller phase and meeting the requirements of high-precision glue application.

[0017] Furthermore, a planetary gear system is provided between the adjusting handwheel and the adjusting transmission shaft, the planetary gear system including a sun gear, planet gears, a planet carrier and a gear ring;

[0018] The sun gear is coaxially connected to the adjusting handwheel;

[0019] The planetary gears are mounted on the planetary gear carrier and mesh with the sun gear and the ring gear. The central axis of the planetary gears is coaxially connected to the adjusting transmission shaft through the planetary gear carrier.

[0020] In this invention, by introducing a planetary gear system between the adjusting handwheel and the adjusting drive shaft, the rotational motion of the adjusting handwheel can be slowed down and transmitted, resulting in a smaller angular change in the adjusting drive shaft. This means that the operator can crank the adjusting handwheel multiple times while the adjusting drive shaft only rotates slightly, thereby achieving high-precision adjustment of the rubber roller phase.

[0021] Furthermore, the adjusting handwheel is a circular disc-shaped wheel located at one end of the adjusting transmission shaft, and a handle is provided on the adjusting handwheel, with the handle facing away from the adjusting transmission shaft.

[0022] Furthermore, the coating machine also includes a fastening wheel, which is a threaded knob installed on the side of the adjusting handwheel relative to the adjusting drive shaft. The fastening wheel engages with a threaded hole in the middle of the adjusting handwheel through the thread, and is used to control the engagement / disengagement state of the adjusting handwheel and the sun gear.

[0023] Furthermore, the gluing machine also includes a conveyor belt for moving the adhesive substrate, and the drive motor drives the conveyor belt to rotate through the motor drive section.

[0024] Furthermore, the conveyor belt includes a conveyor gear, and a gear coaxially arranged on the first conventional shaft to drive the conveyor gear is engaged with the conveyor gear. The conveyor gear is engaged with a fourth synchronous belt, which is engaged with the roller gear of the conveyor belt.

[0025] Furthermore, each of the first, second, third, and fourth synchronous belts has a tensioning pulley on one side that abuts against it, and each is used to adjust the tension of the first, second, third, and fourth synchronous belts.

[0026] Beneficial Effects: This utility model's gluing machine is driven by a drive motor and transmitted through a phase adjustment mechanism, causing the glue roller to rotate and apply glue to the substrate. In this utility model, the phase adjustment mechanism, including a motor drive section, a manual adjustment section, and a glue roller transmission section, ensures smooth transmission. A detachable adjustment handwheel in the manual adjustment section allows for convenient manual adjustment by the operator. By affecting the transmission stroke of the glue roller transmission section, the rotation angle of the glue roller is changed, achieving precise control of the gluing position. This ensures that the gluing area on the glue roller is positioned correctly, allowing for precise gluing of substrates such as paper with intricate patterns, and preventing glue overflow.

Detailed Implementation

[0029] This utility model provides a gluing machine. 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.

[0030] Reference Figure 1 This utility model provides a gluing machine, which includes:

[0031] 100 rubber roller is used to apply adhesive to the substrate.

[0032] The drive motor 200 and the glue applicator phase adjustment mechanism 300 drive the glue roller 100 to rotate and apply glue through the glue applicator phase adjustment mechanism 300.

[0033] The phase adjustment mechanism 300 of the glue applicator includes a motor drive section 310, a manual adjustment section 320 and a glue roller drive section 330 according to the direction of the transmission stroke. The manual adjustment section 320 includes an adjustment drive shaft 321, which is used to adjust the transmission stroke of the glue roller drive section 330 and affect the phase angle of the glue roller 100. The adjustment drive shaft 321 is detachably connected to an adjustment handwheel 322 (not shown in the figure).

[0034] This invention relates to a gluing machine driven by a drive motor 200 and transmitted through a phase adjustment mechanism 300, causing the glue roller 100 to rotate and apply glue to the substrate. The phase adjustment mechanism, comprising a motor drive section 310, a manual adjustment section 320, and a glue roller transmission section 330, ensures smooth transmission. A detachable adjustment handwheel 322 in the manual adjustment section 320 allows for convenient manual adjustment by the operator before startup. By influencing the transmission stroke of the glue roller transmission section 330, the rotation angle of the glue roller 100 is changed, achieving precise control of the gluing position. This ensures the gluing area on the glue roller 100 is positioned correctly, allowing for precise gluing of substrates with intricate patterns, such as paper, and preventing glue overflow. Compared to traditional equipment where frequent motor operation shortens lifespan, this design effectively reduces the number of motor starts and stops during manual adjustment, significantly improving the equipment's lifespan and operational stability. This improvement not only enhances the application precision, meeting the demand for high-precision application, but also increases operational flexibility and convenience, reduces equipment wear and tear, thereby improving production efficiency and product quality.

[0035] In this invention, all the components can be mounted on the frame of the laminating machine.

[0036] In one specific embodiment of this utility model, the motor drive section 310 includes:

[0037] The first drive shaft 311 has two gears coaxially arranged. One gear meshes with the drive gear of the drive motor 200 (not shown in the figure), and the other gear meshes with the first synchronous belt 312.

[0038] The adjusting drive shaft 321 is coaxially equipped with two gears, one gear meshing with the first synchronous belt 312 and the other gear meshing with the second synchronous belt 323;

[0039] The rubber roller drive section 330 includes:

[0040] The third drive shaft 331 has two gears coaxially arranged. One gear meshes with the second synchronous belt 323, and the other gear meshes with the third synchronous belt 332 (not shown in the figure). The third synchronous belt 332 meshes with the roller shaft gear of the rubber roller 100.

[0041] In this invention, by adding an adjusting transmission shaft 321 between the motor drive section 310 and the rubber roller transmission section 330, the rotation angle of the rubber roller 100 can be controlled more precisely. The adjusting transmission shaft 321 can fine-tune the transmission stroke, thereby achieving precise control of the phase of the rubber roller 100 and meeting the requirements of high-precision glue application. Operators can flexibly adjust the phase of the rubber roller 100 by adjusting the adjusting handwheel 322 on the transmission shaft 321 without frequently starting and stopping the drive motor 200, making the adjustment process smoother and more convenient. Since the adjustment function can be achieved by adjusting the adjusting transmission shaft 321, the number of starts and stops of the drive motor 200 and load changes are reduced, thereby reducing motor wear and extending the motor's service life. This invention, through the combined design of multi-segment transmission shafts and synchronous belts, makes the transmission path more reasonable, better adaptable to the overall layout of the equipment, and improves the stability and reliability of the transmission system. At the same time, the modular transmission structure facilitates individual maintenance and adjustment of each transmission segment. For example, the tension and position of the motor drive section 310, the manual adjustment section 320, or the rubber roller drive section 330 can be adjusted independently, simplifying the equipment maintenance process.

[0042] In one specific embodiment of this utility model, a planetary gear system is provided between the adjusting handwheel 322 and the adjusting transmission shaft 321. The planetary gear system includes a sun gear, planet gears, a planet gear carrier, and a gear ring.

[0043] The sun gear and the adjusting handwheel 322 are coaxially connected;

[0044] The planetary gears are mounted on the planetary gear carrier and mesh with the sun gear and the ring gear. The central shaft of the planetary gears is coaxially connected to the adjusting drive shaft 321 through the planetary gear carrier.

[0045] In this invention, by introducing a planetary gear system between the adjusting handwheel 322 and the adjusting transmission shaft 321, the rotational motion of the adjusting handwheel 322 can be slowed down and transmitted, resulting in a smaller angular change in the adjusting transmission shaft 321. This means that the operator can crank the adjusting handwheel 322 multiple times while the adjusting transmission shaft 321 rotates only slightly, thereby achieving high-precision adjustment of the phase of the glue roller 100. This is particularly important for glue applicators that require precise control of the glue application position, significantly improving the accuracy and quality of glue application. The planetary gear system also increases the transmission torque while slowing down the machine, allowing the adjusting transmission shaft 321 to drive the glue roller transmission section 330 more stably. This ensures that even when encountering resistance or requiring a larger torque to adjust the position of the glue roller 100, adjustments can be made smoothly, improving the reliability and stability of the equipment. By introducing a planetary gear system, this invention not only improves the accuracy and reliability of the phase adjustment of the glue applicator but also enhances the operational flexibility of the equipment, providing strong support for high-precision glue application operations.

[0046] In one specific embodiment of this utility model, the adjusting handwheel 322 is a circular disc and is disposed at one end of the adjusting transmission shaft 321. A handle is provided on the adjusting handwheel 322, and the handle faces away from the adjusting transmission shaft 321.

[0047] In this invention, by setting a handle with a suitable orientation on the adjusting handwheel 322, a more comfortable grip position and a larger lever arm are provided for the operator, making it easier to crank the adjusting handwheel 322 and facilitating quick adjustments by hand. Even when multiple turns of precise adjustment are required, it will not cause hand fatigue, thereby achieving precise adjustment of the position of the rubber roller 100.

[0048] The handle can be designed to be foldable, so that it can be placed close to the adjustment handwheel 322 when not in use, reducing the space occupied by the equipment when not in operation, and avoiding interference with other parts or operators.

[0049] In one specific embodiment of this utility model, the gluing machine also includes a fastening wheel, which is a threaded knob installed on the side of the adjusting handwheel 322 relative to the adjusting transmission shaft 321. The fastening wheel engages with a threaded hole in the middle of the adjusting handwheel 322 through the thread, and is used to control the engagement / disengagement state of the adjusting handwheel 322 and the sun gear.

[0050] In this invention, to improve the adjustment accuracy of the rubber roller 100, a planetary gear system is introduced for speed reduction. Consequently, when the motor is turned on for glue application, the adjusting handwheel 322 also rotates at a relatively high speed. Furthermore, a handle may be connected to the adjusting handwheel 322. This rotation can easily cause interference or danger, affecting production safety. This invention, by introducing a fastening wheel design, allows the operator to quickly switch the connection state between the adjusting handwheel 322 and the sun gear through simple tightening or loosening actions. This flexible clutch function allows for easy engagement when adjustment is needed and complete disengagement when adjustment is not required, avoiding unnecessary interference. Before starting the machine, when phase adjustment is required, tightening the fastening wheel allows the adjusting handwheel 322 to rotate freely, achieving precise phase adjustment and keeping the glue roller 100 running stably in the set position, ensuring the accuracy of glue application. After the adjustment is completed, loosening the fastening wheel ensures that the adjusting handwheel 322 is disengaged from the sun gear, preventing the adjusting handwheel 322 from rotating with the adjusting transmission shaft 321 after the drive motor 200 is started, thus eliminating potential dangers.

[0051] In one specific embodiment of this utility model, the glue applicator also includes a conveyor belt for moving the glue-bearing material, and the drive motor 200 drives the conveyor belt to rotate through the motor drive section 310.

[0052] In this invention, the drive motor 200 simultaneously drives the conveyor belt for conveying, and the glue roller 100 rotates to apply glue, so as to apply glue to a large number of substrates.

[0053] In one specific embodiment of this utility model, the conveyor belt includes a conveyor gear 401, and a gear coaxially arranged on the first transmission shaft 311 to mesh with and drive the conveyor gear 401. The conveyor gear 401 meshes with a fourth synchronous belt 402, and the fourth synchronous belt 402 meshes with the roller gear of the conveyor belt.

[0054] In this invention, the power source of the conveyor belt is combined with the main drive system of the gluing machine, avoiding the increased complexity and cost associated with a separate conveyor belt drive motor 200. This also improves the energy efficiency of the equipment. A single drive motor 200 can drive both the glue roller 100 and the conveyor belt, enabling a streamlined gluing process. Furthermore, the combination of gears and synchronous belts facilitates speed matching between the conveyor belt and the glue roller 100. This ensures that the speed of the substrate matches the rotational speed of the glue roller 100 during movement, improving the uniformity and accuracy of the gluing production line over long-term operation. Through its optimized transmission design, this invention enables the gluing machine to achieve more efficient, stable, and precise substrate delivery, providing a strong guarantee for high-quality gluing operations.

[0055] By adjusting the number of teeth on the gears and the specifications of the timing belt, the speed of the conveyor belt can be flexibly changed to adapt to different production speed requirements, thus enhancing the versatility and flexibility of the equipment.

[0056] In one specific embodiment of this utility model, the first synchronous belt 312, the second synchronous belt 323, the third synchronous belt 332 and the fourth synchronous belt 402 are each provided with a tensioning wheel 500 on one side, which is used to adjust the tension of the first synchronous belt 312, the second synchronous belt 323, the third synchronous belt 332 and the fourth synchronous belt 402.

[0057] In this invention, by setting a tensioning wheel 500, the tension of each synchronous belt is ensured, effectively preventing slippage or tooth skipping caused by insufficient tension, and ensuring good meshing between the synchronous belt and the pulley, thereby guaranteeing the accuracy and stability of power transmission. This reliability is crucial for the stable operation of the gluing machine during continuous production. Stable tension helps reduce vibration and swaying of the synchronous belt during operation, thereby reducing the noise level of the equipment and improving the smoothness of operation. This is very beneficial for improving the precision and quality of gluing. In addition, by ensuring the tension of the synchronous belt, it is convenient to manually adjust the phase of the glue roller 100 to a more precise position, avoiding errors caused by slippage. Moreover, the conveyor belt and glue roller 100 in this invention can be driven by the same drive motor 200. By setting the tensioning wheel 500, consistent power output during transmission is ensured, so that the conveyor belt and glue roller 100 in the gluing machine of this invention maintain the required speed coordination.

[0058] 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.
