Description

Technical Field

[0001] This utility model relates to the field of carton packaging production technology, and in particular to a carton gluing mechanism. Background Technology

[0002] In the production of carton packaging, applying glue to the ends of the carton is a key process to ensure packaging quality.

[0003] Currently, existing carton gluing mechanisms consist of a single liner roller and a glue applicator. The liner roller is positioned in the center of the glue applicator, which has four gluing points. The carton is sandwiched between the liner roller and the glue applicator. The liner roller and the glue applicator must rotate synchronously in opposite directions in a tangential state to apply glue to the four gluing points on the carton, ensuring that the ends of the carton are firmly glued after folding, thus guaranteeing the stability of the packaging structure and the integrity of its appearance. However, during production and transportation, the carton is prone to slight deformation at the ends due to humidity and mechanical stress. The single liner roller can only provide intermediate support and cannot accommodate this deformation. This disrupts the tangential relationship between the liner roller and the glue applicator, resulting in fewer or no glue points applied to the carton. Consequently, the carton is not firmly glued after folding, leading to defects such as loose packaging and curling edges, affecting product quality and production efficiency, and increasing quality inspection and rework costs.

[0004] Therefore, there is an urgent need for a carton gluing mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a strip box gluing mechanism that can stably support the strip box, effectively adapt to slight deformation of the strip box, ensure that the strip box end is firmly glued after folding, and guarantee that the quality of gluing and the number of glue dots meet the process requirements.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The carton gluing mechanism includes:

[0008] The glue application assembly includes a first rotating shaft and two glue applicators. The two glue applicators are spaced apart on the first rotating shaft along the axial direction, and the spacing is adapted to the width of the glue application area of ​​the strip box. Each glue applicator has two first glue application points spaced vertically along its inner side and two second glue application points spaced vertically along its outer side.

[0009] The auxiliary pressing assembly includes a second rotating shaft and two sets of liner rollers. The first rotating shaft is arranged parallel to the second rotating shaft. The two sets of liner rollers are spaced apart on the second rotating shaft along the axial direction of the second rotating shaft and correspond one-to-one with the two glue applicators. The distance between the glue applicator and the corresponding liner roller set is adapted to the thickness of the strip box.

[0010] Each roller assembly includes a first roller, a second roller, and a third roller arranged sequentially along the axial direction of the second rotating shaft. When the first rotating shaft rotates synchronously in opposite directions to the second rotating shaft, two first glue application points can extend into the gap between the first roller and the second roller of the corresponding roller assembly, and two second glue application points can extend into the gap between the second roller and the third roller of the corresponding roller assembly, so that when the strip passes between the roller assembly and the glue applicator, the area to be glued is pressed and glued.

[0011] As an optional solution for the carton gluing mechanism, the carton gluing mechanism further includes two gears and a drive component. The two gears are respectively fixed to the ends of the first rotating shaft and the second rotating shaft, and the two gears mesh with each other. The output end of the drive component is connected to one of the gears, and the drive component drives the gear connected to it to rotate, so as to drive the other gear to rotate synchronously in the opposite direction, so that the first rotating shaft and the second rotating shaft rotate synchronously in the opposite direction.

[0012] As an optional solution for the carton gluing mechanism, the first liner roller, the second liner roller, and the third liner roller all adopt a split structure design. The first liner roller, the second liner roller, and the third liner roller are all composed of two symmetrically arranged semi-cylindrical rollers, and the two semi-cylindrical rollers can be joined together to form a complete cylindrical liner roller.

[0013] As an optional solution for the carton gluing mechanism, the carton gluing mechanism also includes fasteners. Each of the two semi-cylindrical rollers has a connecting hole. The direction of the connecting hole is parallel to the radial direction of the semi-cylindrical roller, and the axes of the two connecting holes on the two semi-cylindrical rollers are collinear. The fastener can be inserted through the two connecting holes on the two semi-cylindrical rollers in sequence and then locked, so that the two semi-cylindrical rollers can be detachably fixed.

[0014] As an alternative solution for the carton gluing mechanism, the gluing assembly further includes a first guide roller assembly disposed on the first rotating shaft and located between the two gluing devices; the auxiliary pressing assembly further includes a second guide roller assembly disposed on the second rotating shaft and located between the two liner roller groups, the first guide roller assembly and the second guide roller assembly being configured to convey the carton sandwiched between them.

[0015] As an optional solution for the carton gluing mechanism, the first guide roller assembly includes three first guide rollers, which are evenly distributed and sleeved on the first rotating shaft along the axial direction; the second guide roller assembly includes three second guide rollers, which are evenly distributed and sleeved on the second rotating shaft along the axial direction, with the three first guide rollers corresponding one-to-one with the three second guide rollers.

[0016] As an optional solution for the strip box gluing mechanism, the first, second, and third liner rollers in the liner roller group can be independently adjusted in their installation positions.

[0017] As an alternative to the carton gluing mechanism, the outer circumferential surfaces of the first, second, and third liner rollers in each liner roller group are covered with an elastic layer.

[0018] As an alternative to the carton gluing mechanism, the carton gluing mechanism also includes a detection element configured to detect the position of the carton.

[0019] As an optional solution for the carton gluing mechanism, the carton gluing mechanism also includes a controller, which is communicatively connected to the glue applicator and the detection element. The detection element can transmit the position information of the carton to the controller, and the controller can adjust the glue dispensing timing of the glue applicator according to the position information of the carton.

[0020] Beneficial effects:

[0021] This utility model provides a carton gluing mechanism. When the carton gluing mechanism is working, the first rotating shaft and the second rotating shaft maintain synchronous counter-rotation. In the initial state where no carton passes through, the first gluing point of the gluing device precisely extends into the gap between the first and second liner rollers of the corresponding liner roller group, and the second gluing point extends into the gap between the second and third liner rollers of the corresponding liner roller group. When the carton is conveyed between the liner roller group and the gluing device, the distance between the liner roller group and the gluing device is adapted to the thickness of the carton to form a tight fit. The axial distance between the two gluing devices is adapted to the width of the area to be glued on the carton. The first and second gluing points, together with the gaps on the corresponding liner roller groups, work together to squeeze the area to be glued on the carton. By applying glue to the area to be glued on the carton at multiple points simultaneously, the gluing of the area to be glued on the carton is achieved. When the carton gluing mechanism applies glue dots to the carton, the first, second, and third liner rollers in the liner roller group can stably support the two ends of the carton, effectively adapt to the slight deformation of the carton, and work well with the gluing device to eliminate the problem of missing glue dots. This ensures that the ends of the carton are firmly glued after folding, avoids process quality defects such as loose packaging and curling edges, and guarantees that the quality and quantity of glue dots meet the process requirements. This significantly improves the stability of packaging quality and reduces the cost of quality inspection and rework. Attached Figure Description

[0034] This embodiment discloses a strip box gluing mechanism, such as Figures 1-3 As shown, the carton gluing mechanism includes a gluing component 1 and an auxiliary pressing component 2. The gluing component 1 includes a first rotating shaft 11 and two glue applicators 12. The two glue applicators 12 are spaced apart on the first rotating shaft 11 along its axial direction, and the spacing is adapted to the width of the area to be glued on the carton 100. Each glue applicator 12 has two first glue application points 121 spaced vertically along its radial direction on its inner side and two second glue application points 122 spaced vertically along its outer side. The auxiliary pressing component 2 includes a second rotating shaft 21 and two sets of rollers 22. The first rotating shaft 11 is parallel to the second rotating shaft 21. The two sets of rollers 22 are spaced apart on the second rotating shaft 21 along its axial direction and correspond one-to-one with the two glue applicators 12. The spacing between the glue applicator 12 and the corresponding set of rollers 22 is adapted to the thickness of the carton 100. Each roller assembly 22 includes a first roller 221, a second roller 222, and a third roller 223 arranged sequentially along the axial direction of the second rotating shaft 21. When the first rotating shaft 11 and the second rotating shaft 21 rotate synchronously in opposite directions, two first glue application points 121 can extend into the gap between the first roller 221 and the second roller 222 of the corresponding roller assembly 22, and two second glue application points 122 can extend into the gap between the second roller 222 and the third roller 223 of the corresponding roller assembly 22, so that when the strip box 100 passes between the roller assembly 22 and the glue applicator 12, the area to be glued is pressed and glued.

[0035] like Figures 1-3As shown, when the carton gluing mechanism is working, the first rotating shaft 11 and the second rotating shaft 21 maintain synchronous counter-rotation. In the initial state where no carton 100 passes through, the first gluing point 121 of the gluing device 12 precisely extends into the gap between the first liner roller 221 and the second liner roller 222 of the corresponding liner roller group 22, and the second gluing point 122 extends into the gap between the second liner roller 222 and the third liner roller 223 of the corresponding liner roller group 22. When the carton 100 is conveyed to the liner rollers... When the roller assembly 22 is between the roller assembly 22 and the glue applicator 12, the distance between the roller assembly 22 and the glue applicator 12 is adapted to the thickness of the carton 100 to form a tight fit. The axial distance between the two glue applicators 12 is adapted to the width of the area to be glued on the carton 100. The first glue application point 121 and the second glue application point 122 respectively cooperate with the gap on the corresponding roller assembly 22 to squeeze the area to be glued on the carton 100. By applying glue points at multiple points simultaneously, the glue application of the area to be glued on the carton 100 is achieved. When the carton gluing mechanism applies glue dots to the carton 100, the first liner roller 221, the second liner roller 222, and the third liner roller 223 in the liner roller group 22 can stably support the two ends of the carton 100, effectively adapt to the slight deformation of the carton 100, and cooperate well with the glue applicator 12 to prevent glue dot loss. This ensures that the ends of the carton 100 are firmly glued after folding, avoids loose packaging, curling edges, and other process quality defects, and ensures that the quality of the glue application and the quantity of glue dots meet the process requirements. This significantly improves the stability of packaging quality and reduces the cost of quality inspection and rework.

[0036] It is worth noting that the side opposite to the two glue applicators 12 is defined as the inner side of the glue applicator 12; the side opposite to each other of the two glue applicators 12 is defined as the outer side of the glue applicator 12; the side opposite to each other of the two liner roller groups 22 is defined as the inner side, and the side opposite to each other of the two liner roller groups 22 is defined as the outer side. In this embodiment, each liner roller group 22 is arranged with a first liner roller 221, a second liner roller 222, and a third liner roller 223 arranged sequentially from the inner side to the outer side along the axial direction of the second rotating shaft 21, and the two liner roller groups 22 are symmetrically arranged. The glue application points of the two glue applicators 12 and the gaps of the two liner roller groups 22 are matched, and the glue is applied synchronously at multiple points, which effectively adapts to the slight deformation of the carton 100, eliminates missing glue points, ensures that the ends of the carton 100 are firmly glued after folding, and improves the stability of packaging quality.

[0037] In this embodiment, the diameters of the first liner roller 221, the second liner roller 222, and the third liner roller 223 in the liner roller group 22 are all 70 mm. When the strip box 100 is conveyed through the liner roller group 22, the liner roller group 22 pushes the strip box 100 towards the glue applicator 12. When the glue applicator 12 applies glue, it generates a certain squeezing force on the end of the strip box 100, so that the strip box 100 has a certain degree of bending, ensuring that the quality of the glue application and the number of glue dots meet the process requirements. In other embodiments, the diameters of the first liner roller 221, the second liner roller 222, and the third liner roller 223 in the liner roller group 22 can also be 68 mm, 69 mm, 81 mm, 82 mm, etc., and are not specifically limited here.

[0038] like Figure 1 As shown, the carton gluing mechanism also includes two gears 3 and a drive unit (not shown). The two gears 3 are fixedly mounted on the ends of the first rotating shaft 11 and the second rotating shaft 21, respectively, and the two gears 3 mesh with each other. The output end of the drive unit is connected to one of the gears 3, and the drive unit drives the gear 3 connected to it to rotate, thereby driving the other gear 3 to rotate synchronously in the opposite direction, so that the first rotating shaft 11 and the second rotating shaft 21 rotate synchronously in the opposite direction. Through the cooperation of the two meshing gears 3 and the drive unit, the first rotating shaft 11 and the second rotating shaft 21 are driven to rotate synchronously in the opposite direction, ensuring that the movement of the glue applicator 12 and the liner roller group 22 is precise and synchronized. The stable transmission ensures that the gaps between the first glue application point 121, the second glue application point 122 and the liner roller group 22 are always precisely aligned, ensuring that the glue application pressure of the carton 100 is uniform, and further improving the stability of the glue dots and the reliability of the packaging quality.

[0039] In this embodiment, the output end of the drive unit is connected to the gear 3 on the end of the first rotating shaft 11. The drive unit drives the gear 3 on the end of the first rotating shaft 11 to rotate, thereby driving the gear 3 on the end of the second rotating shaft 21 to rotate synchronously in the opposite direction. This causes the first rotating shaft 11 and the second rotating shaft 21 to rotate synchronously in the opposite direction, thereby driving the glue applicator 12 on the first rotating shaft 11 and the roller group 22 on the second rotating shaft 21 to rotate synchronously in the opposite direction, thus achieving glue application to both ends of the strip box 100.

[0040] In this embodiment, the driving component is a servo motor, stepper motor, etc., and no specific limitation is made here.

[0041] like Figure 2As shown, the first liner roller 221, the second liner roller 222, and the third liner roller 223 all adopt a split structure design. Each of the three rollers is composed of two symmetrically arranged semi-cylindrical rollers, which can be joined together to form a complete cylindrical liner roller. On the one hand, the split semi-cylindrical roller design facilitates installation, debugging, and individual replacement after wear, improving maintenance convenience and the stability of adhesive drop quality. On the other hand, the symmetrical structure ensures the precision of the fit with the applicator 12, maintains stable gaps in the liner roller group 22, and ensures the uniformity of adhesive application pressure at the first adhesive application point 121 and the second adhesive application point 122.

[0042] like Figure 2 As shown, the carton gluing mechanism also includes fasteners (not shown). Each of the two semi-cylindrical rollers has a connecting hole 220. The direction of the connecting hole 220 is parallel to the radial direction of the semi-cylindrical roller, and the axes of the two connecting holes 220 on the two semi-cylindrical rollers are collinear. The fastener can be inserted through the two connecting holes 220 on the two semi-cylindrical rollers and then locked, allowing the two semi-cylindrical rollers to be detachably fixed. The cooperation between the connecting holes 220 and the fasteners enables the semi-cylindrical rollers to be detachably fixed. The two radially collinear connecting holes 220 ensure precise alignment, and the fastener locking ensures the stability of the complete cylindrical roller. This facilitates quick disassembly and maintenance while maintaining the overall accuracy of the roller, further improving replacement efficiency and the operational stability of the carton gluing mechanism.

[0043] Optionally, the fastener is a bolt, which can be passed through the connecting holes 220 on the two semi-cylindrical rollers in sequence, and then locked by a nut to achieve detachable fixing of the two semi-cylindrical rollers. This makes installation and disassembly convenient and facilitates later maintenance and replacement.

[0044] like Figures 3-4 As shown, the glue application assembly 1 also includes a first guide roller assembly 13, which is mounted on the first rotating shaft 11 and located between the two glue applicators 12. The auxiliary pressing assembly 2 also includes a second guide roller assembly 23, which is mounted on the second rotating shaft 21 and located between the two liner roller groups 22. The first guide roller assembly 13 and the second guide roller assembly 23 are used to convey the strip box 100 sandwiched between them. The first guide roller assembly 13 is located between the two glue applicators 12, and the second guide roller assembly 23 is located between the two liner roller groups 22. By clamping and conveying the strip box 100 through the first guide roller assembly 13 and the second guide roller assembly 23, the position of the strip box 100 is kept stable during the glue application process, ensuring the accurate conveying path of the strip box 100, avoiding the positional deviation of the strip box 100 from affecting the glue application accuracy, improving the alignment accuracy between the area to be glued and the glue applicator 12, and ensuring stable glue application quality.

[0045] like Figures 3-4 As shown, the first guide roller assembly 13 includes three first guide rollers 131, which are evenly distributed and sleeved on the first rotating shaft 11 along the axial direction. The second guide roller assembly 23 includes three second guide rollers 231, which are evenly distributed and sleeved on the second rotating shaft 21 along the axial direction. The three first guide rollers 131 and the three second guide rollers 231 correspond one-to-one. The three first guide rollers 131 of the first guide roller assembly 13 and the three second guide rollers 231 of the second guide roller assembly 23 correspond one-to-one, forming a multi-point clamping mechanism to stably transport the strip box 100, preventing the strip box 100 from shifting or wrinkling during transport, ensuring that the area of ​​the strip box 100 to be coated with glue is accurately aligned with the glue applicator 12 and the liner roller group 22, and improving the glue coating position accuracy and transport stability.

[0046] In other embodiments, the number of first guide rollers 131 in the first guide roller assembly 13 may be two, four, five, etc. Correspondingly, the number of second guide rollers 231 in the second guide roller assembly 23 may also be two, four, five, etc., without specific limitation here.

[0047] In this embodiment, the first liner roller 221, the second liner roller 222, and the third liner roller 223 in the liner roller group 22 can be independently adjusted in their installation positions. This independent adjustment allows for precise matching with the first and second glue application points 121 and 122 of the glue applicator 12. By fine-tuning the gap of the liner roller group 22, assembly errors and wear are compensated for, ensuring uniform extrusion pressure during glue application to the carton 100, improving the accuracy of the glue point position, and guaranteeing adhesion and packaging quality stability. Furthermore, by individually adjusting the first liner roller 221, the second liner roller 222, and the third liner roller 223, the glue application needs of carton 100 of different sizes can be met, improving the adaptability of the carton glue application mechanism.

[0048] In this embodiment, the outer circumferential surfaces of the first liner roller 221, the second liner roller 222, and the third liner roller 223 in each liner roller group 22 are all covered with an elastic layer. The elastic layer covering the outer circumference of the first liner roller 221, the second liner roller 222, and the third liner roller 223 in the liner roller group 22 can buffer the compressive stress during glue application, reduce indentations on the surface of the carton 100, enhance the adaptability to slight deformations of the carton 100, ensure uniform glue application, and improve the surface quality and adhesion reliability of the packaging.

[0049] Optionally, the elastic layer is made of silicone. The silicone cushions the pressure when the first liner roller 221, the second liner roller 222, and the third liner roller 223 come into contact with the strip box 100, preventing damage to the strip box 100 from hard contact. At the same time, it enhances the fit between the liner roller group 22 and the glue applicator 12, ensuring uniform pressure at the glue application points and improving the adhesion of the glue dots and the surface quality of the strip box 100.

[0050] In this embodiment, the strip box gluing mechanism also includes a detection element (not shown) for detecting the position of the strip box 100. The detection element monitors the position of the strip box 100 in real time, which can accurately trigger the coordinated action of the glue applicator 12 and the roller assembly 22. This avoids invalid gluing or missed areas when the strip box 100 is misaligned, ensuring that the gluing point accurately corresponds to the area to be glued, reducing quality defects caused by positional errors, and improving the automation accuracy of the gluing process.

[0051] In this embodiment, the strip box gluing mechanism also includes a controller (not shown). The controller is communicatively connected to the gluing applicator 12 and to a detection element. The detection element can transmit the position information of the strip box 100 to the controller, and the controller can adjust the gluing timing of the gluing applicator 12 according to the position information of the strip box 100. Precisely adjusting the gluing timing of the gluing applicator 12 avoids gluing too early or too late due to positional deviation of the strip box 100, ensuring that the glue dots are perfectly matched with the area to be coated, and further improving the gluing accuracy and process stability.

[0052] Specifically, in this embodiment, the detection element is a photoelectric sensor. When the photoelectric sensor is working, the transmitter emits a light beam, which illuminates the strip box 100 or is reflected by a reflector. The receiver receives the reflected or transmitted light and converts the light signal into an electrical signal. The position of the strip box 100 is determined by the change in the electrical signal, and the position information is then transmitted to the controller to achieve precise control of the strip box gluing mechanism.

[0053] Specifically, in this embodiment, the controller is a PLC controller. The PLC controller has high reliability, strong anti-interference ability, can adapt to the industrial environment, and is easy to operate and maintain. It has a fast response speed and can process the position information of the strip box 100 transmitted by the detection component in real time, accurately control the action of the glue applicator 12, and flexibly adapt to changes in production needs.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
