Description

Technical Field

[0001] This utility model relates to the technical field of packaging box processing equipment, specifically a packaging box bonding and molding equipment. Background Technology

[0002] Packaging box bonding molding is a process that uses adhesives to combine dispersed packaging materials into a complete box. First, the cardboard is folded according to the design, glue is applied to the seams, and pressure is applied to fix it after alignment. This process determines the stability of the box structure and is suitable for packaging in many fields such as food and electronics. It is efficient and can ensure a neat appearance.

[0003] However, after some packaging boxes are glued together, the glue applied is difficult to solidify quickly, which can easily cause the packaging boxes to come apart during subsequent packaging, handling and other operations, requiring rework. In addition, the equipment is generally customized and it is difficult to adapt and process packaging boxes of different widths and sizes.

[0004] In order to reduce or avoid the occurrence of packaging box delamination and improve the adaptability of bonding equipment, this application proposes a packaging box bonding and forming equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a packaging box bonding and molding equipment that reduces or avoids packaging box delamination while improving the adaptability of the bonding equipment.

A connecting frame is fixedly connected to the driving end of the electric push rod. Pressure rollers are rotatably connected to the inner walls of the front and rear ends of the connecting frame. Here, the electric push rod pushes the connecting frame, causing the pressure roller to form a straight downward trajectory.

[0009] Further description: Cylinders are fixedly connected to the inner wall of the top center of the concave frame, and connecting frame two is fixedly connected to the driving end of each cylinder. Smoothing rollers are rotatably connected to the inner walls of both the left and right ends of connecting frame two. Here, the cylinders provide the connecting frame two with a downward movement trajectory, and the opposite ends of the smoothing rollers and the opposite ends of the limiting rods are kept on the same horizontal plane.

[0010] Further description: A transfer frame is slidably connected to the lower side of the outer wall of the bending frame.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1-3 A packaging box bonding and molding device includes a transfer table 1. A shielding frame 2 is fixedly connected to the middle of the front and rear sides of the top of the transfer table 1. A cooler 3 is fixedly connected to the right side of the top of the shielding frame 2. Air ducts 12 are fixedly connected to both sides of the output end of the cooler 3. A cavity box 10 is fixedly connected to the other end of each air duct 12. Several air outlet slots 11 are opened on the left side of one opposite end of each cavity box 10. Storage cylinders 4 are fixedly connected to the left sides of both the front and rear ends of the shielding frame 2. A bent pipe 5 is fixedly connected to the bottom of each storage cylinder 4. The other end of each bent pipe 5 penetrates the inner wall of the shielding frame 2 and is fixedly connected to a nozzle 19. Each cavity box 10 has a concave frame 9 fixedly connected to its top end. Each concave frame 9 has a limit rod 8 fixedly connected to its bottom left side. Each limit rod 8 has a bending frame 7 fixedly connected to its opposite side middle. Each shielding frame 2 has an electric push rod 13 fixedly connected to its top left middle. Each electric push rod 13 has a connecting frame 15 fixedly connected to its drive end. Each connecting frame 15 has a pressure roller 17 rotatably connected to its front and rear inner walls. Each concave frame 9 has a cylinder 14 fixedly connected to its top middle inner wall. Each cylinder 14 has a connecting frame 16 fixedly connected to its drive end. Each connecting frame 16 has a smoothing roller 18 rotatably connected to its left and right inner walls.

[0025] To further explain, firstly, the packaged box containing the goods is placed between the two limiting rods 8, ensuring that the unsealed part of the box is positioned above the limiting rods 8. After starting the transfer table 1, the bottom of the box moves into the shielding frame 2 along with the transfer table 1, while the unsealed part is simultaneously conveyed above the limiting rods 8. When the box enters the shielding frame 2 at the set speed, the electric push rod 13 drives the connecting frame 15 to move the pressure roller 17 down to the top of the box, preventing the box from shifting during transport. Subsequently, the adhesive in the storage cylinder 4 is precisely sprayed through the nozzle 19 onto the edge of the box to be bonded. As the transport progresses, when the box reaches between the two smoothing rollers 18, the cylinders 14 on both sides are activated, and the drive end pushes the connecting frame 2 16 to move the smoothing roller 18 down, pressing the unsealed part of the box down to the edge to complete the initial bonding. The rolling and pressing of the smoothing roller 18 on the edge of the box further enhances the tightness of the bond, ensuring a firm fit.

[0026] Finally, the air cooler 3 is turned on, and the cold air it outputs is delivered to the cavity box 10 through the air duct 12 and then evenly discharged through the air outlet 11. When the packaging box is moved between the two cavity boxes 10, it will pass through the area corresponding to the air outlet 11. At this time, the discharged cold air directly acts on the adhesive edge of the packaging box, quickly reducing the temperature of the glue and accelerating its solidification. This step can effectively prevent the packaging box from coming apart during subsequent handling, packing, and transportation operations due to the glue not being completely solidified, reducing rework and ensuring production quality and efficiency.

[0027] In addition, the nozzle 19 is electronically controlled and sprays glue at precise points. In actual use, an infrared sensor will be installed inside the shielding frame 2 to monitor the real-time position of the packaging box and coordinate with the external central control device to ensure the start and stop of each operating component.

[0028] Example 2

[0029] Please see Figure 4 Further, based on Embodiment 1, a transfer frame 6 is slidably connected to the lower side of the outer wall of the bending frame 7. The top of the transfer frame 6 is fixedly connected to the left side of the bottom of the transfer table 1. The inner wall of the transfer frame 6 is fixedly connected to a retaining block 24 on the opposite side of the bending frame 7. The inner walls of the two retaining blocks 24 are rotatably connected to a bidirectional screw 23, which passes through the front and rear sides of the retaining blocks 24. The front and rear sides of the outer wall of the bidirectional screw 23 are respectively threaded to the lower inner wall of the opposite end of the bending frame 7. A motor 22 is fixedly connected to the middle of the right end of the transfer frame 6. The driving end of the motor 22 passes through the inner wall of the transfer frame 6 and is fixedly connected to a driving bevel gear 21. The outer wall of the bidirectional screw 23 is fixedly connected to a driven bevel gear 20 on the rear side of the driving bevel gear 21. The driven bevel gear 20 and the driving bevel gear 21 are meshed with each other.

[0030] To further explain, the distance between the two limiting rods 8 is adjusted according to the width of the packaging box. The motor 22 is started, and the drive end drives the active bevel gear 21 to rotate. The driven bevel gear 20 meshing with it is linked, which in turn drives the bidirectional screw 23 to rotate. With the help of the threaded structure on both sides of the surface of the bidirectional screw 23, the bending frame 7 slides along the thread in the adapter frame 6, and simultaneously drives the limiting rods 8 to move horizontally above the transfer table 1, thus realizing the adjustment of the distance between the two limiting rods 8. At the same time, the concave frame 9 will drive the cavity box 10 and the cylinder 14 to move synchronously, ensuring that the positions of each component are matched.

[0031] Working principle: First, the distance between the two limiting rods 8 is adjusted according to the width of the packaging box. Then, the motor 22 is started, causing its drive end to rotate the active bevel gear 21, which in turn causes the driven bevel gear 20, meshing with one end of the active bevel gear, to rotate the bidirectional screw 23. The threads on both sides of the bidirectional screw 23 then cause the bending frame 7 to slide within the inner threads of the adapter frame 6, thereby displacing the limiting rods 8 above the transfer table 1 and adjusting the distance between the two limiting rods 8. Finally, the concave frame 9 drives the hollow box 1... 0 and cylinder 14 move synchronously. After the product is placed inside the packaging box, it is positioned between the two limit rods 8. The sealed part of the packaging box must be placed on the upper part of the limit rod 8. After the transfer table 1 is started, the bottom of the packaging box moves towards the shielding frame 2 along with the transfer table 1. The unsealed part of the packaging box continues to move on the upper part of the limit rod 8. According to the set device operating speed, when the packaging box moves into the shielding frame 2, the electric push rod 13 will drive the connecting frame 15 to move down with the pressure roller 17 to the top of the packaging box. The packaging box is pressed to prevent it from shifting. Then, the adhesive in the storage cylinder 4 is sprayed onto the edge of the packaging box through the nozzle 19. When the packaging box moves between the two smoothing rollers 18, the two cylinders 14 are activated, causing their drive ends to push the connecting frame 16 and move the smoothing rollers 18 downwards. This causes the smoothing rollers 18 to press the unsealed part of the packaging box down to the edge of the packaging box for bonding. As the two smoothing rollers 18 roll on one side of the packaging box, the bonding effect can be further improved. By activating the cold air blower 3, cold air is generated at its output end and transported to the hollow box 10 along the connected air duct 12, and then discharged through the air outlet 11. When the packaging box moves between the two hollow boxes 10, it will pass through the part with the air outlet 11. At this time, the cold air discharged from the air outlet 11 will cool one side of the packaging box, thereby improving the effect of rapid curing of the adhesive. This prevents the packaging box with incompletely cured adhesive from coming unglued during subsequent handling, packing, and transportation, which would cause rework problems.
