Description

Technical Field

[0001] This utility model relates to the field of packaging carton processing technology, specifically to an automatic bonding device for packaging cartons. Background Technology

[0002] Packaging carton bonding equipment is a post-processing device used in carton manufacturing, primarily for bonding cardboard through processes such as gluing and folding. Currently, after the cardboard sheets are cut to the appropriate shape, it is usually necessary to fold both sides of the cardboard sheet before subsequent gluing and bonding. For fragmented orders, manual folding of the sides of the sheet is required using creases. However, some cardboard sheets do not have reinforced structures and lack support after folding, making them prone to realignment and affecting the subsequent gluing effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic bonding device for packaging cartons. It has the advantage of being able to position and fix the side panels of the cartons after folding, thereby facilitating glue application. This solves the problem in existing technologies where some cardboard does not employ a reinforced structure, lacks support after folding, and is prone to repositioning, thus affecting the subsequent glue application effect.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automatic bonding device for packaging cartons includes a worktable serving as the main body of the device. An L-shaped bracket is fixedly connected to the worktable. An electric push rod for pressing the bottom plate of the carton is mounted on the L-shaped bracket. A positioning mechanism for effectively fixing the side plates of the carton is provided on the electric push rod. The positioning mechanism includes a connecting block fixedly connected to the movable end of the electric push rod. Small electric telescopic rods are mounted on multiple sides of the connecting block. Fixing blocks are fixedly connected to the movable ends of the multiple small electric telescopic rods. Right-angle brackets are fixedly connected to the bottom of the multiple fixing blocks to correspond to the four corners inside the carton. Sliding grooves are opened on both sides of the multiple right-angle brackets. Sliding blocks are slidably connected in the multiple sliding grooves. A spring is fixedly connected to one side of the sliding block. A clamping plate is fixedly connected to one end of the spring to clamp and fix the folded four side plates to prevent them from resetting.

[0005] Preferably, a rubber pad is fixedly connected to one side of each of the multiple clamping plates to avoid damage to the cardboard, and a stop strip is fixedly connected to one side of the slider to facilitate adaptation to different side plate heights.

[0006] Preferably, a circular plate is rotatably connected to the bottom of the L-shaped bracket, an adjusting turntable is installed on the top of the L-shaped bracket, a damping rotating rod is installed between the adjusting turntable and the circular plate, and the bottom of the circular plate is connected to an electric push rod.

[0007] Preferably, the top of the workbench has a circular groove, a rotating rod is installed at the center of the circular groove, and a base is fixedly connected to the rotating rod.

[0008] Preferably, a plurality of ball bearings are installed on the side of the chassis to reduce the friction between the chassis and the side of the circular groove.

[0009] Preferably, the bottom of the workbench is equipped with multiple support columns, and the top surface of the chassis is provided with roller patterns.

[0010] By means of the above technical solution, this utility model provides an automatic bonding device for packaging cartons, which has at least the following beneficial effects: 1. This utility model enables the device to position and fix the four side panels of the folded carton by setting a positioning mechanism. By adjusting the small electric telescopic rod, the positions of multiple right-angle frames correspond to the four corners inside the carton. The electric push rod drives the multiple right-angle frames to descend, thereby fixing the bottom plate of the carton. During the descent of the right-angle frames, multiple baffles are blocked by the side plates, allowing the slider to move in a direction within the slide groove. After the bottom plate is fixed, the clamping plate is pulled to further fix the four side panels of the carton, ensuring the stability of the subsequent glue coating of the carton.

[0011] 2. This utility model enables the carton to be easily rotated after it is fixed by setting an adjusting turntable and a damping rod. After the glue is applied to one side of the carton, the carton can be rotated synchronously by rotating the adjusting turntable to apply glue to the other side, which improves the glue application efficiency. The rollers and balls on the chassis keep the carton and the chassis relatively stationary, avoiding wear on the bottom of the carton. Attached Figure Description

[0014] 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.

[0015] For fragmented orders, manual folding of the board material on both sides by pressing lines is required. However, some cardboard does not have a reinforced structure and lacks support after folding, making it prone to repositioning and affecting the subsequent gluing effect. The following describes an automatic bonding device for packaging cartons provided by some embodiments of this utility model with reference to the accompanying drawings.

[0016] Example 1: To ensure the coating effect of the cardboard boxes, combined with Figures 1-4 As shown, an automatic bonding device for packaging cartons is proposed. The device consists of a workbench 1 as the main body, an L-shaped bracket 3 fixedly connected to the workbench 1, an electric push rod 4 installed on the L-shaped bracket 3, which is used to press and fix the bottom plate of the carton, and a positioning mechanism 5 is provided on the electric push rod 4, which is used to effectively fix the side plate of the carton.

[0017] To ensure the proper fit of the carton side panels, a positioning mechanism 5 is proposed. A connecting block 501 is fixedly connected to the movable end of an electric push rod 4. Multiple small electric telescopic rods 502 are mounted on various sides of the connecting block 501. Fixing blocks 503 are fixedly connected to the movable ends of the multiple small electric telescopic rods 502. Right-angle brackets 504 are fixedly connected to the bottom of the multiple fixing blocks 503 to correspond to the four corners inside the carton. Slide grooves 505 are provided on both sides of the multiple right-angle brackets 504. Sliding sliders 506 are slidably connected within the multiple slide grooves 505. A spring 508 is fixedly connected to one side of the slider 506. A clamping plate 509 is fixedly connected to one end of the spring 508 to clamp and fix the folded side panels, preventing them from resetting. Rubber clamps are fixedly connected to one side of each clamping plate 509. Pad 510 is used to prevent damage to the cardboard. A stop bar 507 is fixedly connected to one side of the slider 506 to accommodate different side panel heights. By adjusting the small electric telescopic rod 502, the positions of multiple right-angle frames 504 correspond to the four corners inside the carton, which can accommodate square cartons of different sizes. The electric push rod 4 drives the multiple right-angle frames 504 to descend, so that the right-angle frames 504 correspond to the four corners inside the carton, thereby fixing the bottom plate of the carton. During the descent of the right-angle frames 504, the multiple stop bars 507 are blocked by the side panels, so that the slider 506 moves in a direction within the slide groove 505. After the bottom plate is fixed, the clamping plate 509 is pulled by the spring 508 to further fix the four side panels of the carton, preventing repositioning and ensuring the stability of the subsequent glue coating of the carton.

[0018] Example 2: The technical solution proposed in Example 1 is used to solve the problem that some cardboard in the prior art does not adopt a reinforced structure, lacks support after folding, and is prone to repositioning, thus affecting the subsequent gluing effect. However, after the bottom plate and side plate of the carton are fixed, the carton should be able to rotate easily in order to stir and change the position of the coating during gluing.

[0019] To facilitate easy switching of the glue application location on the cardboard box, combined with Figure 1 and Figure 4As shown, a circular plate 9 is rotatably connected to the bottom of an L-shaped bracket 3. An adjusting turntable 11 is installed on the top of the L-shaped bracket 3. A damping rotating rod 10 is installed between the adjusting turntable 11 and the circular plate 9. The bottom of the circular plate 9 is connected to an electric push rod 4. A circular groove 6 is opened on the top of the workbench 1. A rotating rod is installed in the center of the circular groove 6. A base plate 7 is fixedly connected to the rotating rod. Multiple ball bearings 8 are installed on the side of the base plate 7 to reduce the friction between the base plate 7 and the side of the circular groove 6. Multiple support columns 2 are installed at the bottom of the workbench 1. The top surface of the base plate 7 is provided with roller patterns to increase the friction between the base plate 7 and the bottom of the carton. After the glue is applied to one side of the carton, the carton is rotated synchronously by rotating the adjusting turntable 11, causing multiple right-angle brackets 504 to apply glue to the other side, thereby improving the glue application efficiency. The roller patterns and ball bearings 8 on the base plate 7 keep the carton relatively stationary during rotation, avoiding wear on the bottom of the carton and improving the glue application efficiency of the carton.
