[0002] In the carton manufacturing process, the gluing machine is a key piece of equipment for achieving carton forming and bonding. However, after the gluing machine completes the gluing, the carton is prone to positional shifts when transported via a transfer structure (such as a conveyor belt), leading to misalignment at the joints and severely affecting the carton's forming quality, structural strength, and subsequent stacking and packaging efficiency. Currently, some production lines still rely on manual alignment, which is not only inefficient and labor-intensive but also lacks precision, failing to meet the demands of modern high-speed production. Existing simple mechanical alignment devices generally suffer from poor adaptability, inability to flexibly adjust to different carton sizes, and potential damage to the carton surface. Therefore, there is an urgent need for a device that can be integrated into the production line, is highly automated, and can flexibly and non-destructively complete carton alignment and sorting to improve production automation and product qualification rates.

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.

[0013] Please see Figure 1 - Figure 3 A carton alignment device for a carton gluing machine includes a transfer table 1, a mounting frame 2, an alignment component and a flattening component. A conveyor belt 101 is provided on the transfer table 1, the mounting frame 2 is provided on the top of the transfer table 1, and the flattening component is provided on the top of the inner wall of the mounting frame 2. The inner walls of both sides of the mounting frame 2 are provided with first mounting grooves 201. A lead screw 3 is provided in the first mounting groove 201. The bottom of the lead screw 3 is rotatably connected to the first mounting groove 201, and the top of the lead screw 3 is driven to the output end of the motor 301 located on the top of the mounting frame 2. A transmission block 4 is threadedly connected to the lead screw 3. The two sides of the first mounting groove 201 are provided with second mounting grooves 202. A guide rod 5 is provided in the second mounting groove 202. A slider 6 is slidably connected to the guide rod 5. An alignment component is provided on the side of the transmission block 4 and the slider 6 near the transfer table 1. The alignment assembly includes a first connecting plate 7, a first electric telescopic rod 8, and a clamping plate 9. The transmission block 4 and the slider 6 are fixedly connected to one side of the first connecting plate 7 near the transfer table 1. The other side of the first connecting plate 7 is fixedly connected to one end of a plurality of first electric telescopic rods 8. The other end of the first electric telescopic rods 8 is fixedly connected to one side of the clamping plate 9. A flattening assembly is provided on the top of the inner wall of the mounting frame 2.

[0014] Through the above technical solution, a lead screw 3 driven by a top motor 301 is installed in the first mounting groove 201 on both sides of the mounting frame 2. The transmission block 4 threaded on the lead screw 3 is fixedly connected to one side of the first connecting plate 7. At the same time, the guide rod 5 and the slider 6 slidably connected to it, which are located in the second mounting groove 202, are connected to the first connecting plate 7 to form a stable guide support structure. The other side of the first connecting plate 7 is connected to the clamping plate 9 through multiple first electric telescopic rods 8, thus forming a complete alignment assembly. This structure ensures that when the motor 301 is driven, the transmission block 4 can drive the entire alignment assembly to rise and fall smoothly along the lead screw 3, and the cooperation between the guide rod 5 and the slider 6 effectively prevents deflection, allowing the clamping plate 9 to be accurately adjusted to a suitable height according to the thickness of the carton, providing a reliable foundation for subsequent clamping and alignment actions.

[0015] This utility model provides a technical solution in which the flattening assembly includes a second electric telescopic rod 10, a second connecting plate 11, a telescopic rod 12, a mounting plate 14, and a pressure plate 18. Multiple second electric telescopic rods 10 are provided on the top of the inner wall of the mounting bracket 2. The bottom output end of the second electric telescopic rod 10 is fixedly connected to the top of the second connecting plate 11. Telescopic rods 12 are provided at the four corners of the bottom of the second connecting plate 11. The bottom of the telescopic rods 12 is fixedly connected to the top of the mounting plate 14. A first spring 13 is provided on the outer periphery of the telescopic rods 12. Both ends of the mounting plate 14 are detachably connected to the pressure plate 18 through the mounting components.

[0016] Through the above technical solution, multiple second electric telescopic rods 10 set on the top of the mounting frame 2 drive the second connecting plate 11 to rise and fall as a whole; the four corners of the bottom of the second connecting plate 11 are connected to the mounting plate 14 through telescopic rods 12, and the first springs 13 set on the outer periphery of the telescopic rods 12 together form an elastic buffer system; the mounting plate 14 is detachably connected to the pressure plate 18 that performs the flattening operation through the mounting components at both ends of its end.

[0017] This structure allows the pressure to be buffered by the deformation of the first spring 13 when the second electric telescopic rod 10 is driven to press down, thereby transforming rigid pressing into flexible contact. This effectively avoids indentation damage to the carton surface caused by excessive pressure or uneven carton thickness. At the same time, the modular connection method facilitates the quick replacement of pressure plates 18 of different specifications according to the carton size, significantly improving the applicability of the device and the convenience of operation and maintenance.

[0018] This utility model provides a technical solution in which the installation component includes a second spring 15, a limiting plate 16, and a limiting block 17. Both ends of the mounting plate 14 are provided with a third mounting groove 1401. A second spring 15 is provided in the middle of the third mounting groove 1401. Both ends of the second spring 15 are fixedly connected to one side of the limiting plate 16. Openings are provided above both ends of the second spring 15 at the top of the third mounting groove 1401. The top of the limiting plate 16 passes through the opening and can move within the opening. The other side of the limiting plate 16 is fixedly connected to one end of the limiting block 17. The top of the pressure plate 18 is provided with a groove 19. The inner wall of the groove 19 is provided with a slot 1901 corresponding to the position of the limiting block 17. The bottom of the limiting block 17, which is away from the limiting plate 16, is provided with an inclined surface.

[0019] With the above technical solution, during installation, the groove 19 on the top of the pressure plate 18 is aligned with the mounting plate 14 and pushed upward. The inclined surface at the bottom of the limiting block 17 is squeezed when it contacts the edge of the groove 19, which causes the limiting plate 16 to compress inward and the second spring 15 to retract into the third mounting groove 1401, so that the pressure plate 18 can be smoothly installed. When the limiting block 17 moves to the position aligned with the groove 1901 on the inner wall of the groove 19, the restoring force of the second spring 15 pushes the limiting plates 16 and the limiting block 17 at both ends to extend outward and be inserted into the groove 1901, thereby firmly locking the pressure plate 18.

[0020] During disassembly, simply pinch the tops of the exposed limiting plates 16 at both ends of the mounting plate 14 to compress the second spring 15 again and cause the limiting block 17 to disengage from the slot 1901, and the pressure plate 18 can be removed.

[0021] The working principle of this utility model is as follows: After the glued carton is conveyed by the conveyor belt 101 to the designated position below the mounting frame 2, the conveyor belt 101 stops; then, the motor 301 starts, drives the lead screw 3 to rotate, and drives the transmission block 4 threaded to it to move in the vertical direction. At the same time, the slider 6 slides on the guide rod 5 to provide stable guidance, thereby driving the alignment assembly consisting of the first connecting plate 7, the first electric telescopic rod 8 and the clamping plate 9 to rise and fall to a suitable height; then, the first electric telescopic rod 8 extends synchronously, pushing the clamping plates 9 on both sides to move towards each other, clamping and correcting the position of the carton from both sides, and completing the alignment. After alignment, the flattening assembly begins operation. The second electric telescopic rod 10 extends, pushing the second connecting plate 11 downward. Through the telescopic rod 12 and the buffer spring 13, the mounting plate 14 and the pressure plate 18 are flexibly pressed onto the top of the carton, making it flat. After the flattening process is completed, each component is reset in sequence, the conveyor belt 101 restarts, and the processed carton is sent out to enter the next process.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
