Description

Technical Field

[0001] This utility model relates to the field of cardboard box sealing technology, and in particular to a hot melt adhesive coating device for sealing cardboard boxes. Background Technology

[0002] Hot melt adhesive coating equipment for sealing cardboard boxes achieves efficient and secure sealing by heating hot melt adhesive and precisely applying it to the seams. Based on automation levels, it can be categorized into manual, semi-automatic, fully automatic, and customized types. Manual models are portable and flexible, but rely on manual operation. Semi-automatic models use a conveyor belt and fixed nozzles, requiring manual placement of cardboard boxes. Fully automatic models integrate automatic feeding, shaping, and adhesive application, requiring no manual intervention throughout the process. Customized models can be designed with specific needs in mind. These devices generally feature hot melt adhesive compatibility, coating control, temperature control, and cardboard box compatibility. Selection should consider automation requirements and actual usage scenarios. During operation, the equipment should be preheated and settings adjusted. Regular cleaning, inspection, and maintenance are essential to ensure equipment lifespan and sealing quality.

[0003] Hot melt adhesive coating equipment for sealing cardboard boxes includes an adhesive storage unit for storing hot melt adhesive raw materials, equipped with heating to melt the adhesive, a coating execution structure, different types of nozzles responsible for accurately delivering the melted adhesive to the carton seam, a common conveyor belt for moving the carton along a set path in conjunction with the coating action, and a pressing structure, mostly roller assemblies, that applies pressure to the carton seam after coating to enhance the adhesion. Some equipment includes a shaping structure that adjusts the shape of the carton through mechanical components to ensure neat seams. Manual or semi-automatic models also have handheld operating components, while fully automatic models include automatic feeding and sorting mechanical components to ensure the mechanical coordination of the entire sealing process. However, existing hot melt adhesive coating equipment for sealing cardboard boxes is prone to cardboard box misalignment during operation, causing the adhesive coating to deviate from the seam, and the carton is also prone to deformation, resulting in poor pressing and adhesion, insufficient sealing strength, and unstable sealing quality and an increased failure rate.

Detailed Implementation

[0017] 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.

[0018] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a hot melt adhesive coating device for sealing the edges of cardboard boxes. The device includes a support base 1, a clamping mechanism 2 mounted on the top of the outer wall of the support base 1, which stabilizes the processing position of the cardboard box. A limiting mechanism 3 is mounted on the right side of the outer wall of the clamping mechanism 2, which automatically adapts to different specifications of adhesive. The clamping mechanism 2 includes a fixing block 201 mounted on the top of the outer wall of the support base 1. A connecting box 202 is fixedly connected to the right side of the outer wall of the fixing block 201. A bearing 203 is fixedly connected to the front side of the outer wall of the connecting box 202. A connecting block 204 is mounted on the rear side of the outer wall of the bearing 203. A roller 204 is rotatably connected to the front side of the outer wall of the connecting block 204. 05. A connecting block 206 is installed on the right side of the outer wall of roller 205. Roller 207 is fixedly connected to the front side of the outer wall of connecting block 206. A rotating component 208 is installed on the rear side of the outer wall of roller 207. The rotating component 208 includes a rotating handle 2081. The rotating handle 2081 is installed on the front side of the outer wall of connecting box 202. A threaded rod 2082 is fixedly connected to the rear side of the outer wall of rotating handle 2081. A slider 2083 is threadedly connected to the middle of the outer wall of threaded rod 2082. A connecting tube 2084 is fixedly connected to the rear side of the outer wall of slider 2083. A connecting block 2085 is fixedly connected to the rear side of the outer wall of connecting tube 2084. A connecting column 2086 is rotatably connected to the right side of the outer wall of connecting block 2085. Specifically, rotating the rotary handle 2081 installed on the front side of the connecting box 202 can drive the threaded rod 2082 to rotate smoothly within the connecting box 202 via the bearing 203. This drives the slider 2083 via threaded transmission, causing the connecting tube 2084 to slide along the guide structure of the connecting box 202. This pushes the connecting block 2085 to rotate the connecting post 2086 at an angle. The roller 205 installed on the front side of the connecting block 204 in the middle of the connecting post 2086 cooperates with the roller 207 on the front side of the connecting block 206 to form a clamping mechanism. The system is used to fix the cardboard boxes to be processed. When the connecting column 2086 rotates through the connecting block 204, the clamping force of the roller 207 and roller 205 can be adjusted, so that the heated coating adhesive is evenly applied through the roller 207 and tightly adhered to the seam of the cardboard box. This can stabilize and fix the position of the cardboard box, prevent the cardboard box from shifting during the sealing process, ensure that the coating adhesive is aligned with the seam, reduce the deformation of the cardboard box caused by uneven force, significantly improve the pressing and bonding degree, enhance the sealing firmness, and effectively optimize the sealing quality and operational stability of the equipment.

The outer walls of the gear 3052 are meshed with racks 3053 on both the left and right sides. The rear side of the outer wall of the right rack 3053 is fixedly connected to the slider 3054. The top of the outer wall of the slider 3054 is fixedly connected to the sliding ring 3055. Specifically, starting the servo motor 3051 installed in the fixed box 304 outputs a stable torque to drive the gear 3052 to rotate around the axis. Through the meshing transmission between the gear 3052 and the rack 3053, the two matching racks 3053 are driven to move synchronously in opposite directions. This, in turn, drives the slider 3054 fixed on the top of the rack 3053 to slide smoothly in the guide groove of the slide rail 303. The limiting plates 302 fixed on the front and rear sides of the support plate 301 form a rigid constraint, which can limit the maximum travel of the slider 3054 and avoid component interference. Finally, the distance between the two sliding rings 3055 can be precisely adjusted, which can quickly adapt to coating rolls of different specifications, eliminate the step of manual adjustment, greatly simplify the feeding and installation process, shorten the operation time, and avoid installation deviations caused by specification mismatch through mechanical positioning, ensuring the installation accuracy of coating rolls, effectively improving the feeding efficiency of the equipment and the adaptability to multiple specifications of materials, and enhancing production continuity.

[0020] Reference Figure 1 , Figure 2 and Figure 3Support columns 4 are fixedly connected to the four corners of the bottom of the outer wall of the support base 1. Shock-absorbing pads 5 are fixedly connected to the bottom of the outer wall of the multiple support columns 4. A display 6 is installed on the front side of the outer wall of the support base 1. A keyboard 7 is set on the right side of the outer wall of the display 6. A fixed frame 8 is installed on the top of the outer wall of the support base 1. A rotating shaft 9 is rotatably connected to the middle of the inner wall of the fixed frame 8. A fixed frame 10 is set on the right side of the outer wall of the rotating shaft 9. A rotating shaft 11 is rotatably connected to the middle of the inner wall of the fixed frame 10. A fixed frame 12 is fixedly connected to the top of the outer wall of the support base 1. A heating tube 13 is installed on the bottom of the inner wall of the fixed frame 12. A servo motor 14 is installed on the front side of the outer wall of the fixed frame 12. The servo motor 14 adopts the ILA1F572PB1A0 servo motor 14. According to the control mode, it is adjusted by feedback to achieve high-precision positioning. The output end of the servo motor 14 is fixedly connected to the rotating shaft 15. Specifically, the shock-absorbing pads 5 installed on the support column 4 are used to improve the shock absorption and anti-slip effect of the lifting device, while the display 6 is used to display the parameter information when the device is working, the keyboard 7 is used to edit the relevant parameter information, the rotating shaft 9 at the top of the fixed frame 1 8 is used to assist the operation of the limiting mechanism 3, the rotating shaft 11 inside the fixed frame 2 10 is used to assist the operation of the clamping mechanism 2, the heating tube 13 installed in the fixed frame 3 12 is used to melt the coating adhesive, and the rotating shaft 3 15 is driven to rotate by the servo motor 2 14.

[0021] Working principle: Rotating the rotating handle 2081 installed on the front side of the connecting box 202 allows the threaded rod 2082 to rotate within the connecting box 202 via the bearing 203. This drives the slider 2083 to slide the connecting tube 2084 within the connecting box 202, which in turn pushes the connecting block 2085 to rotate the connecting column 2086. The roller 205, installed in front of the connecting block 204 in the middle of the connecting column 2086, is used to clamp the cardboard box to be processed with the roller 207. When the connecting column 2086 rotates through the connecting block 204, the roller 207 installed in front of the connecting block 206 clamps the roller 207 with the roller 205. The heated adhesive is then bonded to the cardboard box via the roller 207, which can stably fix the position of the cardboard box, prevent the cardboard box from shifting during sealing, ensure that the adhesive is aligned with the seam, reduce cardboard box deformation, improve the pressing and bonding degree, enhance the sealing firmness, and optimize the sealing quality and stability of the equipment. Activating the servo motor 3051 installed in the fixed box 304 drives the gear 3052 to rotate, which in turn drives the two racks 3053 that mesh with the gear 3052 to move in opposite directions. This causes the slider 3054 fixed on the top of the rack 3053 to slide on the slide rail 303. The limiting plates 302 fixed on the front and rear sides of the support plate 301 limit the range of movement, thereby adjusting the distance between the two sliding rings 3055. This allows for automatic adaptation to different specifications of coating adhesive without manual adjustment, simplifying the material loading and installation process, reducing operation time, avoiding installation deviations caused by specification mismatch, ensuring the accuracy of coating adhesive installation, and improving the equipment loading efficiency and adaptability.
