[0046] Furthermore, in order to use different types of cardboard boxes, the spacing between the first conveyor belt 211 and the second conveyor belt 212 can be flexibly adjusted by the adjustment unit 213 to adapt to the conveying requirements of cardboard boxes of different sizes, ensuring that the cardboard boxes are stable and do not deform during the conveying process, thereby improving the versatility and production efficiency of the equipment.

[0047] The removal unit 224 described above can be an actuator such as a cylinder, push rod, or linear motor. The appropriate removal method can be selected based on actual needs to ensure smooth removal of the carton. Furthermore, the lifting power unit 222 can be electrically, pneumatically, or hydraulically driven (e.g., cylinders, hydraulic cylinders, or linear motors) to provide stable and controllable lifting force, adapting to different production environments. The overall structure is compact, easy to operate, and has low maintenance costs, significantly improving the practicality and market competitiveness of the carton sealing machine.

[0048] like Figure 1As shown, in this embodiment, the frame 10 includes a housing frame 101 and a raised frame 102 mounted on the housing frame 101; a horizontal conveying unit 21, a glue spraying unit 23, and a lifting power unit 222 are mounted on the housing frame 101, while a folding plate 223 and a removal unit 224 are mounted on the raised frame 102. Thus, the housing frame 101 provides a stable support structure and mounting space on the top surface, facilitating the integration and coordinated operation of each unit; simultaneously, the space within the housing frame 101 can also be used to install auxiliary facilities such as electrical wiring, air supply pipes, or hydraulic pipes, maintaining the overall clean appearance of the equipment.

[0049] Furthermore, the elevated frame 102 forms a tiered frame 10, which facilitates the installation of corresponding structures, such as the folded edge plate 223 and the removal unit 224, above the horizontal conveying unit 21, making the entire structure more three-dimensional, optimizing space utilization, and reducing the size of the equipment.

[0050] Furthermore, in this embodiment, a movable wheel 104 and a fixed support foot are provided below the housing frame 101 to facilitate flexible movement and stable fixation of the equipment in different working scenarios, thereby improving the flexibility and practicality of use.

[0051] In this embodiment, the elevated frame 102 is provided with an output slide 1021 with its starting end aligned with the removal unit 224, so that the sealed cardboard box can be smoothly slid down from the folding plate 223 to the collection area, avoiding accumulation and blockage, and ensuring the continuity of the production process.

[0052] like Figure 2 As shown, in this embodiment, a support plate 214 is provided between the first conveyor belt 211 and the second conveyor belt 212, and a top pressure plate 215 is provided on the frame 10 above the support plate 214. In this way, the support plate 214 and the top pressure plate 215 can better limit the conveying of the paper box, prevent the paper box from shifting or deforming during the conveying process, and ensure the stability and forming quality of the paper box.

[0053] like Figure 2 As shown, in this embodiment, the top pressure plate 215 is provided with a first strip-shaped hole 2151 for adjusting its own horizontal height, and / or the support plate 214 is provided with a lifting power unit that drives its own lifting and lowering. The lifting power unit can be a cylinder, hydraulic cylinder, or linear motor, etc. By adjusting the height of the top pressure plate 215 or the support plate 214, the needs of cartons of different thicknesses can be met, ensuring that the cartons remain flat during transportation and improving sealing quality. At the same time, the adjustment mechanism of the top pressure plate 215 simplifies the operation process, reduces maintenance difficulty, and further enhances the adaptability and working efficiency of the equipment. This allows for adjustment according to the size of the cartons, further improving the adaptability and flexibility of the equipment and meeting diverse production needs.

[0054] like Figure 2 As shown, in this embodiment, the first conveyor belt 211 is provided with a plurality of first baffles 2111 arranged at equal intervals, and the second conveyor belt 212 is provided with a plurality of second baffles 2121 arranged at equal intervals.

Each width-limiting plate 2131 is provided with a second strip-shaped hole 2132 or a horizontal power unit for adjusting the distance between itself and the other width-limiting plate 2131. The horizontal power unit can be a cylinder, hydraulic cylinder, or linear motor, etc. By adjusting the distance between the two width-limiting plates 2131, the needs of cartons of different widths can be met. The output of the end-limiting switches ensures that the cartons remain stable during transport, avoiding deviation or tilting due to varying widths, thereby improving the overall forming effect and sealing quality of the cartons, and ensuring efficient and precise production.

[0056] Furthermore, the folding plate 223 is provided with a moving unit 225 that moves itself to adjust the distance between itself and the cardboard box. The moving unit 225 can be a cylinder, hydraulic cylinder or linear motor, etc., and is adjusted synchronously with the width limiting plate 2131 to fold the cardboard box.

[0057] like Figure 2 and Figure 4 As shown, in this embodiment, the frame 10 is equipped with a position sensor 103 electrically connected to the glue spraying unit 23. The position sensor 103 can be of various types, such as an infrared sensor or a photoelectric sensor. The infrared sensor is model IR-2025, and the photoelectric sensor is model PS-3000, both capable of accurately detecting the position of the cardboard box and ensuring accurate glue spraying timing. That is, when the cardboard box is transported to the designated position, the position sensor 103 immediately triggers the glue spraying unit 23 to precisely spray glue, followed by folding by the folding plate 223 to ensure the cardboard box is firmly bonded. This completes the overall automated processing of the cardboard box, reducing manual intervention, ensuring consistent cardboard box forming quality, improving production efficiency, reducing costs, and meeting the high-efficiency and precise needs of the modern packaging industry.

[0058] like Figure 1As shown, this embodiment also includes a controller 30. The position sensor 103 is electrically connected to the input terminal of the controller 30, and the glue spraying unit 23 is electrically connected to the output terminal of the controller 30. The horizontal conveying unit 21 and the lifting unit 22 are also electrically connected to the output terminal of the controller 30. The controller 30 can be a PLC or a microcontroller, such as a Siemens S7-1200 PLC or a 51 series microcontroller, or it can be used with computer or other control equipment. The controller 30 enables automated folding and glue spraying operations, ensuring the quality of the cardboard box forming.

[0059] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
