Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard coating technology, and in particular to a cardboard coating device. Background Technology
[0002] In the paperboard processing industry, paperboard often requires the bonding of multiple layers of paper. For example, corrugated paperboard is composed of a corrugated core paper interlayer and paperboard, which has high mechanical strength. Traditional paperboard manufacturing plants mostly use glue coating equipment to automatically apply glue in order to reduce the intensity of manual labor, avoid the problem of uneven glue application by manual labor, and improve processing efficiency.
[0003] According to the Chinese announcement number CN222325551U, this utility model relates to the field of paperboard production technology, specifically to a paperboard gluing device, comprising: a base, on which a conveying mechanism for conveying paperboard is provided; and a gluing mechanism, which includes a U-shaped plate fixedly connected to the upper end of the base, a hollow rod inserted into the side wall of the U-shaped plate, a gluing roller fixedly connected to the side wall of the hollow rod, the gluing roller penetrating the side wall of the U-shaped plate, a plurality of first holes opened in the side wall of the hollow rod, and a plurality of second holes corresponding one-to-one with the plurality of first holes opened in the side wall of the gluing roller.
[0004] The aforementioned patent describes that "synchronously driving the first motor 12 and the second motor 19 to rotate, at which time the first gear 13 will drive the hollow rod 3 to rotate through the second gear 11, so that the coating roller 4 rotates to uniformly coat the cardboard, and under the action of multiple third gears 17 and toothed belts 18, multiple conveying rollers 16 can be driven to rotate, thereby realizing the coating process during the cardboard conveying process." However, in current cardboard coating, manual feeding of the cardboard is required, and it is not convenient to adjust the size of different cardboards, thus reducing the coating efficiency. Therefore, a cardboard coating device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cardboard coating device, which aims to improve the low efficiency of existing coating methods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cardboard coating device includes multiple support columns, with a fixed plate 1 fixedly connected inside each support column. A processing mechanism is provided at the top of the fixed plate 1, and a support plate is fixedly connected to the top of the fixed plate 1. A cleaning mechanism is provided inside the support plate. The processing mechanism includes a conveyor belt, which is sleeved on the top of the fixed plate 1. Two fixed plates 2 are fixedly connected to the top of the fixed plate 1. Guide columns are fixedly connected to adjacent sides of the two fixed plates 2. Two fixed blocks 2 and two fixed blocks 1 are slidably connected to the outside of the guide columns. A shielding frame and a baffle are fixedly connected to the outside of the two fixed blocks 1 and the two fixed blocks 2, respectively. Guide wheels are fixedly connected to the bottom ends of the two fixed blocks 1. A coating assembly is provided outside the support plate.
[0008] The above technical solution involves: a processing mechanism and a support plate at the top of a fixed plate; a cleaning mechanism within the support plate; and multiple support columns providing a solid and stable foundation for the entire device. This effectively ensures the stability of the device during long-term, high-intensity operation, preventing deviations in the gluing position due to shaking, thereby improving the accuracy of gluing and the product qualification rate. The conveyor belt smoothly and continuously transports the board, ensuring that the cardboard enters the gluing area at a uniform speed along a predetermined route, reducing the tedious manual handling and positioning operations, lowering labor costs. The shielding frame effectively restricts the transport of the board, and the baffle precisely limits the board, preventing it from shifting during transport and ensuring accurate gluing position, thus improving product quality. The guide wheels further guide and limit the board, ensuring that it always maintains a straight line, providing a strong guarantee for the smooth progress of subsequent gluing processes.
[0009] As a further description of the above technical solution:
[0010] The adhesive application assembly includes a connecting plate, which is externally fixedly connected to the rear end of the support plate. A pressure roller is rotatably connected to the bottom end of the connecting plate, and an adhesive application component is fixedly connected to the rear end of the connecting plate.
[0011] The above technical solution involves the pressure roller applying moderate pressure to the board as it passes through, ensuring full contact between the board and the gluing components. This guarantees even application of adhesive to the board surface, ensuring the stability and uniformity of the gluing operation, improving gluing quality, and effectively preventing product defects caused by uneven gluing. The gluing components precisely apply adhesive to the board according to a preset method, completing the gluing task. This precise gluing performance contributes to the production of high-quality coated paperboard products.
[0012] As a further description of the above technical solution:
[0013] Multiple plates are provided on adjacent sides of the two baffles, and the bottom ends of the multiple plates are located at the top of the conveyor belt;
[0014] Through the above technical solution, this layout design allows multiple boards to be arranged in an orderly manner on the conveyor belt. With the power of the conveyor belt, they pass through the gluing area in sequence, realizing continuous and efficient gluing operations. There is no need for frequent machine stops for reloading, which greatly improves production efficiency and meets the needs of large-scale production. At the same time, the limiting function of the baffles ensures that the boards will not shift or become disordered during the transmission process, ensuring the accuracy and consistency of gluing and improving the stability of product quality.
[0015] As a further description of the above technical solution:
[0016] The cleaning mechanism includes an eccentric wheel, the eccentric wheel is fixedly connected to the front end of the pressure roller, a fixed column is fixedly connected to the front end of the eccentric wheel, a transmission rod is rotatably connected to the front end of the fixed column, a cleaning brush is rotatably connected to the end of the transmission rod away from the fixed column, and an adjustment component is provided on the outside of the support plate.
[0017] Through the above technical solution: the cleaning mechanism cleverly utilizes the power of the rotating pressure roller to drive the eccentric wheel to rotate, and then converts the circumferential motion of the eccentric wheel into the reciprocating oscillation of the cleaning brush through the fixed column and transmission rod. The cleaning brush scrapes the top of the board before applying glue, which can effectively remove dust, debris and other impurities from the surface, avoid these contaminants from affecting the adhesion between the glue and the board, ensure the quality of glue application, reduce the defect rate and improve the reliability of the product. The setting of the adjustment component provides a method for flexible adjustment of the equipment, and can be operated accordingly according to different production needs.
[0018] As a further description of the above technical solution:
[0019] The top end of the cleaning brush is rotatably connected to the bottom end of the connecting plate, and the bottom end of the guide wheel is in contact with the top end of the plate.
[0020] The above technical solution, with its rotating connection between the cleaning brush and the connecting plate, ensures that the cleaning brush can flexibly swing back and forth with the connecting plate as the fulcrum, thereby cleaning the top of the board comprehensively and effectively, improving the cleaning effect. The contact between the guide wheel and the top of the board plays a good guiding and limiting role during the board's transmission process, ensuring that the board always moves along the predetermined path.
[0021] As a further description of the above technical solution:
[0022] The adjusting assembly includes a stud, the stud being externally threaded into the interior of the support plate, a sliding block being slidably connected to the outside of the stud, a gear being fixedly connected to the outside of the sliding block, and a rack being slidably connected to the interior of the support plate, with the rack and the gear being meshed together.
[0023] The above technical solution utilizes the principle of threaded transmission by rotating the stud, allowing the sliding block to slide smoothly within the support plate. This efficiently converts the rotational motion of the stud into linear motion. The sliding block drives the gear to rotate, and the meshing transmission between the gear and the rack plate enables the rack plate to slide precisely within the support plate. This design provides a precise and convenient way to adjust the height of the gluing assembly and cleaning mechanism. Operators can easily adjust the working height of the equipment according to the different thicknesses of the cardboard, enhancing the versatility and adaptability of the equipment and improving production efficiency and product quality.
[0024] As a further description of the above technical solution:
[0025] The bottom end of the rack plate is fixedly connected to the top end of the connecting plate, and the outside of the connecting plate is slidably connected to the inside of the support plate.
[0026] The above technical solution connects the rack plate and the connecting plate, allowing the rack plate to slide directly and move the connecting plate up and down, thereby enabling precise adjustment of the height of the adhesive application assembly and the cleaning mechanism.
[0027] As a further description of the above technical solution:
[0028] The gear is externally slidably connected to the inside of the support plate, and a control handle is fixedly connected to the end of the stud away from the sliding block.
[0029] The above technical solution ensures precise meshing between the rack and gear through gear rotation, while the control handle provides operators with a convenient and intuitive operating component.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, the adjustable fixing block adapts to plates of different widths, the conveyor belt automatically feeds the material, the guide wheel guides and limits the movement, and the pressure roller squeezes and cooperates with the glue application component to automatically apply glue, which effectively reduces the glue preparation time, significantly improves the glue application efficiency, and has good glue application and bonding effect.
[0032] 2. In this utility model, during the glue application process, the pressure roller rotates to drive the eccentric wheel, which in turn causes the cleaning brush to repeatedly scrape the top of the board to clean the surface, ensuring the glue application quality. At the same time, the operator can flexibly adjust the height of the glue application components and cleaning mechanism by controlling the handle, stud, gear rack and pinion and other structures to adapt to different thicknesses of cardboard.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a cardboard coating device, comprising multiple support columns 1, which provide stable support for the entire device, ensuring its stability during operation and preventing the coating effect from being affected by shaking. A fixing plate 2 is fixedly connected inside the multiple support columns 1. A processing mechanism 3 is provided at the top of the fixing plate 2. The processing mechanism 3 is the core part for cardboard coating. The proper arrangement of the processing mechanism 3 can efficiently complete the coating operation on the cardboard. A support plate 4 is fixedly connected to the top of the fixing plate 2. The support plate 4 provides a foundation for the installation and support of components such as the cleaning mechanism 5 and the coating assembly 309, ensuring that these components can work stably. The processing mechanism 3 includes a conveyor belt 301, which is sleeved on the top of the fixing plate 2. The conveyor belt 301 can smoothly and continuously transport the board 6, allowing the board 6 to move to the coating area along a predetermined route.
[0041] Two fixing plates 302 are fixedly connected to the top of fixing plate 1 2. Guide posts 303 are fixedly connected to the adjacent sides of the two fixing plates 302. Two fixing blocks 306 and two fixing blocks 304 are slidably connected to the outside of the guide posts 303. The two fixing plates 302 provide fixed support for the guide posts 303, ensuring the stability of the guide posts 303, and thus ensuring that the fixing blocks 304 and 306 can slide smoothly. This allows the fixing blocks 304 and 306 to be adjusted in position according to the width of the plate 6, improving the versatility of the device. A shielding frame is fixedly connected to the outside of each of the two fixing blocks 304 and 306. 305 and baffle 307, the bottom of the baffle 305 and the top of the conveyor belt 301 are left with a gap, only one plate 6 is allowed on the top of the conveyor belt 301 on one side. The baffle 307 can limit the plate 6 to ensure that the plate 6 will not deviate during the transmission. The bottom of the two fixed blocks 304 are fixedly connected with guide wheels 308. The guide wheels 308 can guide and limit the plate 6 to keep the plate 6 moving in a straight line during the transmission and ensure the accuracy of the glue application position. The support plate 4 is provided with a glue application component 309. The glue application component 309 is the key component to realize the glue application of the plate 6. The glue application component 309 can evenly apply the glue to the surface of the plate 6.
[0042] The glue application assembly 309 includes a connecting plate 3091, which is externally fixedly connected to the rear end of the support plate 4. The connecting plate 3091 provides a structural foundation for the installation and connection of the pressure roller 3092 and the glue application component 3093, ensuring that the pressure roller 3092 and the glue application component 3093 can work together. The bottom end of the connecting plate 3091 is rotatably connected to the pressure roller 3092. The pressure roller 3092 squeezes the plate 6 when it passes through, so that the plate 6 is in full contact with the glue application component 3093, ensuring the stability and uniformity of the glue application operation. The rear end of the connecting plate 3091 is fixedly connected to the glue application component 3093, which can apply glue to the surface of the plate 6 in a preset manner to complete the glue application task. Multiple plates 6 are arranged on the adjacent side of the two baffles 307. The bottom ends of the multiple plates 6 are set at the top of the conveyor belt 301. The conveyor belt 301 can drive the plates 6 to pass through the glue application area in sequence to realize continuous glue application operation.
[0043] Specifically, multiple support columns 1 provide stable support. The processing mechanism 3 on the fixed plate 1 2 is responsible for the cardboard processing flow. The conveyor belt 301 stably transports the board 6. The guide column 303 supported by the fixed plate 2 302, the fixed block 1 304 and the fixed block 2 306 can be adjusted according to the width of the board 6. The shielding frame 305 and the baffle 307 connected to it play a limiting role. The guide wheel 308 ensures the linear movement of the board 6. In the glue application assembly 309, the connecting plate 3091 supports the pressure roller 3092 and the glue application component 3093. The pressure roller 3092 squeezes the board 6 to ensure stable and uniform glue application. The glue application component 3093 completes the glue application. The entire processing mechanism 3 realizes automatic feeding and glue application, reduces preparation time, and greatly improves processing efficiency.
[0044] Reference Figures 2 to 4 The cleaning mechanism 5 includes an eccentric wheel 501, which is externally fixedly connected to the front end of the pressure roller 3092. When the pressure roller 3092 rotates, it can synchronously drive the eccentric wheel 501 to rotate, providing a power source for the cleaning mechanism 5. A fixed column 502 is fixedly connected to the front end of the eccentric wheel 501, and a transmission rod 503 is rotatably connected to the front end of the fixed column 502. A cleaning brush 504 is rotatably connected to the end of the transmission rod 503 away from the fixed column 502. The fixed column 502 acts as a bridge connecting the eccentric wheel 501 and the transmission rod 503, transmitting the rotational motion of the eccentric wheel 501 to the transmission rod 503. The transmission rod 503 rotates under the drive of the eccentric wheel 501, converting the circular motion of the eccentric wheel 501 into the reciprocating oscillation of the cleaning brush 504. The cleaning brush 504 oscillates back and forth at the bottom end of the connecting plate 3091 under the pull of the transmission rod 503, scraping the top of the plate 6 to effectively remove dust and impurities and ensure the quality of the adhesive coating.
[0045] An adjustment component 505 is provided on the outside of the support plate 4. The adjustment component 505 can adjust the height of the glue application component 309 and the cleaning mechanism 5 according to the thickness of the board 6 to adapt to the glue application and cleaning needs of boards 6 with different thicknesses. The top end of the cleaning brush 504 is rotatably connected to the bottom end of the connecting plate 3091. This connection method ensures that the cleaning brush 504 can swing back and forth with the connecting plate 3091 as the fulcrum. The bottom end of the guide wheel 308 contacts the top end of the board 6 to ensure that the guide wheel 308 can effectively guide and limit the board 6. The adjustment component 505 includes a stud 5052. The external thread of the stud 5052 is connected to the inside of the support plate 4. The height can be adjusted by rotating the stud 5052. A sliding block 5055 is slidably connected to the outside of the stud 5052. The sliding block 5055 slides inside the support plate 4 as the stud 5052 rotates, converting the rotational motion of the stud 5052 into linear motion.
[0046] A gear 5053 is fixedly connected to the outside of the sliding block 5055. The sliding block 5055 drives the gear 5053 to rotate, providing power for the sliding of the rack plate 5054. The rack plate 5054 is slidably connected inside the support plate 4. The rack plate 5054 and the gear 5053 are meshed. The rotation of the gear 5053 will drive the rack plate 5054 to slide inside the support plate 4. The bottom end of the rack plate 5054 is fixedly connected to the top end of the connecting plate 3091. The sliding of the rack plate 5054 will drive the connecting plate 3091 to slide. The 091 moves up and down, thereby adjusting the height of the glue application assembly 309 and the cleaning mechanism 5. The external sliding connection of the connecting plate 3091 is inside the support plate 4, ensuring that the connecting plate 3091 can move up and down smoothly under the support of the support plate 4. The end of the stud 5052 away from the sliding block 5055 is fixedly connected to the control handle 5051. The operator can easily control the rotation of the stud 5052 by rotating the control handle 5051, thereby adjusting the height of the glue application assembly 309 and the cleaning mechanism 5.
[0047] Specifically, the cleaning mechanism 5 uses the rotation of the pressure roller 3092 to drive the eccentric wheel 501, which in turn causes the cleaning brush 504 to swing back and forth at the bottom of the connecting plate 3091 through the fixed column 502 and the transmission rod 503, scraping the top of the board 6 to effectively remove dust and impurities and ensure the quality of the adhesive coating. The adjustment component 505 includes a stud 5052, a sliding block 5055, a gear 5053 and a rack plate 5054. The operator can easily adjust the height of the adhesive coating component 309 and the cleaning mechanism 5 by rotating the control handle 5051 to adapt to different thicknesses of cardboard, thus enhancing the applicability of the device.
[0048] Working principle: When the processing personnel need to apply glue to the cardboard, the fixing block 2 306 and fixing block 1 304 are adjusted to slide outside the guide post 303 according to the width of the board 6, so as to accommodate boards 6 of different sizes. Multiple boards 6 inside the two baffles 307 will be guided one by one by the conveyor belt 301 and move as the conveyor belt 301 slides. At the same time, the guide wheel 308 will guide and limit the board 6. At this time, the pressure roller 3092 will squeeze the cardboard to ensure that the glue application component 3093 can stably and automatically apply glue to the board 6. Through automatic feeding and glue application, the preparation time for glue application is reduced and the processing efficiency is improved. After the glue application is completed, the operator manually glues the boards and sends them to the stacking area.
[0049] While the gluing operation is underway, the rotation of the pressure roller 3092 drives the eccentric wheel 501 to rotate. The eccentric wheel 501 pulls the transmission rod 503 to rotate via the fixed column 502, causing the transmission rod 503 to pull the cleaning brush 504 to swing back and forth at the bottom of the connecting plate 3091, thereby scraping the top of the board 6 to achieve a cleaning effect and prevent dust and impurities from affecting the gluing operation, thus ensuring the quality of the gluing. At the same time, the operator adjusts the height of the gluing component 309 and the cleaning mechanism 5 according to the thickness of the cardboard. By rotating the control pin 5051, the stud 5052 drives the sliding block 5055 to rotate inside the support plate 4, thereby causing the gear 5053 to rotate, so that the rack plate 5054 slides inside the support plate 4, ultimately achieving the adjustment of the height of the connecting plate 3091.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
