Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper production equipment, and in particular to the corrugated paper sizing structure. Background Technology

[0002] Corrugated cardboard is an indispensable material in the modern packaging industry, and the sizing process is a key step that determines the bonding strength of the cardboard and the quality of the final product. The corrugated cardboard sizing system, as the core equipment in this process, directly affects production efficiency and product qualification rate.

[0003] Traditional corrugated paper sizing structures typically involve applying adhesive to the corrugated core paper using a sizing roller, and using a metering rod to control the thickness of the adhesive layer on the roller, thereby adjusting the amount of adhesive applied. However, in existing technologies, the adjustment of the metering rod position is often rather crude, relying heavily on manual adjustment or simple mechanical transmission, making it difficult to achieve fast and precise positioning. This results in an inability to accurately match the optimal amount of adhesive when facing production demands of different basis weights and speeds, easily leading to unstable adhesive application and affecting the bonding quality of the corrugated board.

[0004] Meanwhile, during high-speed production, the sizing roller inevitably experiences vibrations and impacts due to paper movement and mechanical transmission. These vibrations are directly transmitted to the entire sizing structure, especially between the metering bar and the sizing roller. Even with precise initial adjustments, this vibration can cause momentary changes in the gap between the metering bar and the sizing roller, thereby disrupting the uniformity of the glue layer and creating irregular glue marks on the paper surface, severely reducing sizing quality. Furthermore, continuous impacts and vibrations accelerate the wear of critical components such as the sizing roller and metering bar, shortening the equipment's lifespan.

[0005] In summary, existing corrugated paper sizing structures generally suffer from the core problem of balancing adjustment precision and operational stability. Simply improving adjustment precision or implementing basic vibration reduction measures cannot fundamentally guarantee the uniformity and reliability of sizing under high-speed operation.

[0006] Therefore, this utility model proposes a corrugated paper sizing structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing corrugated paper gluing structure, such as insufficient accuracy in adjusting the position of the metering rod and the susceptibility of the gluing roller to impact and vibration during the gluing process, which affects the uniformity of gluing and thus the product quality and equipment service life, this utility model aims to provide a corrugated paper gluing structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a corrugated paper gluing structure, including an operating table, a metering rod and a gluing roller, and the operating table is provided with an adjustment mechanism and a buffer mechanism.

[0009] The adjustment mechanism includes a mounting box containing an electric push rod. The drive end of the electric push rod is connected to a connecting plate, and a transmission rod is rotatably connected to the connecting plate. The other end of the transmission rod is rotatably connected to a sliding block. The top of the sliding block is rotatably connected to a transmission rod, and the other end of the transmission rod is rotatably connected to a sliding plate. A measuring rod is rotatably connected inside the sliding plate. The adjustment mechanism moves the measuring rod by extending and retracting the electric push rod to adjust its position.

[0010] Furthermore, the buffer mechanism includes a guide rod, a second limiting rod, two second sliding blocks, a first spring, a third transmission rod, a connecting block, and the second spring. The guide rod is fixedly connected to the operating table. The glue roller is rotatably connected to the third transmission rod through the connecting block. The third transmission rod drives the second sliding block to slide along the second limiting rod. The two ends of the first spring are respectively connected between the two second sliding blocks. The second limiting rod slides along the guide rod. One end of the second spring is connected to the inside of the operating table, and the other end is connected to the outer wall of the second limiting rod. The first spring and the second spring together form a double buffer structure.

[0011] Preferably, the adjustment mechanism further includes a limiting component, which includes a limiting plate and a limiting rod. The limiting rod and the limiting plate are fixedly connected inside the mounting box. A sliding block is slidably fitted to the outer wall of the limiting plate, and the other end of the measuring rod is slidably fitted to the inner wall groove of the limiting plate.

[0012] Furthermore, the design of the limiting component ensures that the metering rod slides smoothly along the preset trajectory when it moves under the drive of the electric push rod, effectively avoiding lateral deviation or shaking of the metering rod, thereby ensuring precise control of the amount of adhesive applied and improving the uniformity and stability of adhesive application.

[0013] Preferably, the connecting plate has two transmission rods rotatably connected inside.

[0014] Furthermore, using two transmission rods connected together can make the force during the transmission process more balanced, reduce the off-center load that may be caused by unilateral transmission, thereby improving the stability and transmission accuracy of the adjustment mechanism, and also enhancing the overall rigidity of the mechanism.

[0015] Preferably, when the application roller is subjected to pressure, the pressure is transmitted to the transmission rod three through the connecting block. The transmission rod three deflects and pushes the sliding block two to slide along the limiting rod two, thereby compressing or stretching the spring one to achieve initial buffering.

[0016] Furthermore, the initial buffer mechanism can quickly respond through the spring when the application roller is subjected to instantaneous pressure, absorbing most of the impact energy in time, effectively preventing the pressure from being directly transmitted to other critical components, protecting the application roller and metering rod, and reducing wear.

[0017] Preferably, when the second sliding block slides, it causes the second limiting rod to slide along the guide rod, thereby compressing or stretching the second spring to achieve further buffering.

[0018] Furthermore, based on the initial buffering, the second spring acts as a second-level buffer, which can absorb residual or continuous impact force again, forming a more complete buffering effect, completely eliminating the slight vibrations that may occur during the application of adhesive, and ensuring the ultimate uniformity of adhesive application.

[0019] Preferably, in the adjustment mechanism, the extension and retraction of the electric push rod can precisely control the position of the measuring rod.

[0020] Furthermore, by precisely controlling the stroke of the electric actuator, the metering rod can be adjusted at the millimeter or even sub-millimeter level, thereby meeting the requirements for fine adjustments to different corrugated paper types, glue viscosity, and glue application amount, greatly improving production flexibility and product quality consistency.

[0021] Preferably, the guide rod and the second limiting rod have a sliding fit structure.

[0022] Furthermore, the adoption of a sliding fit structure ensures that the second limiting rod can slide smoothly and without obstruction on the guide rod, reducing friction and jamming, ensuring the response speed and buffering efficiency of the buffer mechanism when subjected to impact, and improving the reliability of the system.

[0023] This utility model has the following beneficial effects: 1. This utility model solves the problem of insufficient position accuracy of the metering rod adjustment mechanism in the existing corrugated paper gluing structure by setting a precision adjustment mechanism driven by an electric push rod. It realizes precise control of the position of the metering rod, greatly improves the accuracy of gluing metering, and meets different gluing needs.

[0024] 2. This utility model solves the problems of uneven glue application and shortened equipment lifespan caused by impact and vibration on the glue application roller in the prior art by setting a buffer mechanism composed of double springs. It effectively absorbs the impact and vibration on the glue application roller during the glue application process, ensures the uniformity of glue application, and extends the service life of the equipment.

[0025] 3. This utility model solves the problem of the inability to balance the accuracy and stability of glue application in the prior art through the synergistic effect of the adjustment mechanism and the buffer mechanism, making the glue application metering operation accurate and efficient, and significantly improving product quality.

[0026] 4. This utility model solves the problem of inaccurate glue application caused by the easy deviation of the measuring rod in the prior art by using the limiting component to stably guide the movement trajectory of each component in the adjustment mechanism, thus ensuring the smoothness and accuracy of the measuring rod movement.

[0029] The following combination Figures 1-4 This application will be described in further detail below.

[0030] Reference Figures 1 to 4 This utility model provides a corrugated paper gluing structure, which aims to solve the problems of insufficient gluing amount adjustment accuracy and poor gluing roller operation stability in the existing technology.

[0031] The corrugated paper sizing structure includes an operating table 1, an adjusting mechanism 2, a metering rod 3, a buffer mechanism 4, and a sizing roller 5. The adjusting mechanism 2 and the buffer mechanism 4 are both installed on the operating table 1. The adjusting mechanism 2 is used to set the position of the metering rod 3, and the buffer mechanism 4 is used to ensure the stable operation of the sizing roller 5. The two work together to achieve accurate and efficient sizing metering.

[0032] The adjustment mechanism 2 uses the mounting box 21 as its operating frame to adjust the position of the measuring rod 3. The mounting box 21 is fixedly connected to the operating table 1. An electric push rod 22 is installed inside the mounting box 21. The drive end of the electric push rod 22 is fixedly connected to the connecting plate 23. Two transmission rods 24 are rotatably connected inside the connecting plate 23. The other end of each transmission rod 24 is rotatably connected to a sliding block 25. A transmission rod 26 is rotatably connected to the top of the sliding block 25. The other end of each transmission rod 26 is rotatably connected to a sliding plate 27. The measuring rod 3 is rotatably connected inside the sliding plate 27. By activating the electric push rod 22, its extension and retraction movement is achieved through the linkage of the connecting plate 23, transmission rods 24, sliding block 25, and transmission rod 26, ultimately pushing the measuring rod 3. The sliding plate 27 and the internal measuring rod 3 move, and the extension and retraction of the electric push rod 22 can precisely control the position of the measuring rod 3. To ensure the smoothness and accuracy of the adjustment process, the adjustment mechanism 2 is also equipped with a limiting component 28 located in the mounting box 21. The limiting component 28 includes a limiting rod 281 and a limiting plate 282. The limiting rod 281 and the limiting plate 282 are fixed together in the mounting box 21. The outer side of the sliding block 25 slides and engages with the outer wall of the limiting plate 282, and the other end of the measuring rod 3 slides and engages with the groove opened in the inner wall of the limiting plate 282. The limiting rod 281 and the limiting plate 282 together ensure the stability of the trajectory of each moving part in the adjustment mechanism 2, effectively preventing the measuring rod 3 from deviating during the movement.

[0033] The buffer mechanism 4 is mounted on a guide rod 41, which is fixedly connected to the inside of the operating table 1. A limiting rod 42, which can reciprocate along its length, is slidably fitted on the guide rod 41. Two sliding blocks 43 are symmetrically slidably connected to both sides of the limiting rod 42. The two sliding blocks 43 are connected by a spring 44, and the two ends of the spring 44 are fixed to the corresponding sliding blocks 43. One end of a spring 47 is also connected to the outer wall of the limiting rod 42, and the other end of the spring 47 is fixed to the inside of the operating table 1. The glue roller 5 is rotatably connected to the transmission rod 45 through a connecting block 46. One end of the transmission rod 45 is connected to the connecting block 46, and the other end is rotatably connected to both sliding blocks 43.

[0034] In the assembled state, the pressure or impact experienced by the glue application roller 5 during glue application is transmitted to the transmission rod 45 via the connecting block 46, causing the transmission rod 45 to deflect. This, in turn, pushes the two sliding blocks 43 to slide towards or away from each other along the limiting rod 42. This sliding process compresses or stretches the spring 44 connected between them, and the deformation of the spring 44 achieves initial absorption of impact energy. At the same time, the sliding block 43 drives the limiting rod 42 to slide along the guide rod 41. This sliding process compresses or stretches the spring 47, and the deformation of the spring 47 further absorbs impact energy. This double spring buffer structure composed of spring 44 and spring 47 ensures that the glue application roller 5 can receive effective and multi-level buffer protection when subjected to impact, greatly improving the uniformity and stability of the glue application process.

[0035] In a preferred embodiment, the adjusting mechanism 2 further includes a limiting component 28, which includes a limiting plate 282 and a limiting rod 281. The limiting rod 281 and the limiting plate 282 are fixedly connected inside the mounting box 21. The outer side of the sliding block 25 is slidably fitted to the outer wall of the limiting plate 282. The other end of the measuring rod 3 is slidably fitted to a groove opened in the inner wall of the limiting plate 282. The connecting plate 23 is rotatably connected to two transmission rods 24. These two transmission rods 24 work together to drive the sliding block 25 to move.

[0036] When the glue application roller 5 is subjected to pressure, the pressure is transmitted to the transmission rod 45 through the connecting block 46. The transmission rod 45 deflects and pushes the sliding block 43 to slide along the limiting rod 42, thereby compressing or stretching the spring 44. The deformation of the spring 44 achieves initial buffering. Subsequently, when the sliding block 43 slides, it drives the limiting rod 42 to slide along the guide rod 41, thereby compressing or stretching the spring 47. The deformation of the spring 47 achieves further buffering. This double buffering structure effectively ensures the uniformity of glue application. The guide rod 41 and the limiting rod 42 adopt a sliding fit structure to reduce frictional resistance and ensure smooth and reliable buffering action.

[0037] The implementation principle of this application embodiment is as follows: the operating table 1 sets the position of the metering rod 3 through the adjustment mechanism 2, and the buffer mechanism 4 ensures the stable operation of the glue application roller 5. The two work together to make the glue application metering operation of the operating table 1 accurate and efficient, and improve the glue application quality and equipment service life. The adjustment mechanism 2 uses the mounting box 21 as its operating frame. It drives the metering rod 3 to adjust its position. Activating the electric push rod 22 inside the mounting box 21 moves the connecting plate 23. The two transmission rods 24 rotatably connected inside the connecting plate 23 deflect accordingly, pushing the sliding block 25 rotatably connected at its other end to slide along the outer wall of the limiting plate 282 in the limiting assembly 28. The sliding block 25 drives the top-rotating transmission rod 26 to deflect, pushing the sliding plate 27 and the internally rotating metering rod 3 to move. The other end of the metering rod 3 slides along the groove on the inner wall of the limiting plate 282, ensuring smooth movement. The position of the metering rod 3 can be precisely controlled by the extension and retraction of the electric push rod 22, meeting different glue application metering requirements. The limiting rod 281 and the limiting plate 282 together ensure the stability of the movement trajectory of each component, preventing the metering rod 3 from deviating.

[0038] The buffer mechanism 4 uses the guide rod 41 as its mounting base to provide buffer protection for the glue application roller 5. During the glue application process, the pressure on the glue application roller 5 is transmitted to the connecting block 46. The connecting block 46 pushes the transmission rod 3 45 to deflect. The transmission rod 3 45 drives the sliding block 2 43 to slide along the limiting rod 2 42. The compression or tension spring 1 44 is connected to two sliding blocks 2 43 at both ends. The deformation of the spring 1 44 initially buffers the pressure. At the same time, the limiting rod 2 42 slides along the guide rod 41. One end of the compression or tension spring 2 47 is connected to the inside of the operating table 1, and the other end is connected to the outer wall of the limiting rod 2 42. The deformation of the spring 2 47 further absorbs the impact. The double spring buffer structure effectively weakens the vibration and impact on the glue application roller 5, ensuring the uniformity of glue application. The guide rod 41 and the limiting rod 2 42 ensure the smooth sliding of each component and ensure the reliable operation of the buffer mechanism 4.
