[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0018] Please see Figure 1-5 In the field of color printing and packaging production, material feeding is a crucial initial step in accurately and efficiently transporting raw cardboard boxes to the production line (such as belt conveyors). However, traditional material feeding structures have many limitations and are difficult to adapt to the high requirements of flexibility and efficiency in modern production.

[0019] First, existing equipment generally lacks effective height adjustment and adaptive clamping mechanisms. Because the printed packaging cartons vary in size and thickness, fixed-height feeding devices cannot accommodate raw materials of different specifications, leading to frequent machine stops for manual adjustment and severely impacting production efficiency. Simultaneously, traditional pushing or clamping mechanisms, when in contact with the cartons, are prone to uneven or excessive pressure, causing scratches, deformation, or damage to the printed layers of the soft-surfaced cartons, directly affecting the quality of the final product.

[0020] Secondly, for lightweight and structurally unstable thin printing materials, traditional mechanical clamping and pushing methods are often unreliable. During handling, the materials are prone to slippage or detachment, causing loading failures or even production line interruptions. Although vacuum adsorption technology has been applied to material handling in other fields, how to intelligently combine it with mechanical extrusion and pushing mechanisms in the color printing and packaging loading process, automatically switching or coordinating its operation according to the characteristics of the materials to achieve multi-functionality, remains a technical challenge. Therefore, this application protects an adjustable feeding structure for color printing packaging. Raw material cartons are evenly placed on a platform. A pair of lifting screw modules in the processing sidewalls of the processing bracket on the platform operate, driving a lifting support plate. This allows the equipment at the bottom of the lifting support plate to be adjusted according to the height of the cartons. The lifting support plate drives a concave support block for stable lifting. The concave support block drives multiple extrusion drive shafts, which in turn drive extrusion rollers. Multiple convex telescopic grooves on the extrusion rollers, along with telescopic spring columns inside these grooves, drive convex telescopic blocks and arc-shaped extrusion blocks for stable expansion. The feeding drive mechanism operates, driving a feeding gear set at its drive end. The feeding gear set drives multiple extrusion drive shafts, which in turn drive the extrusion wheels to rotate vertically, thus achieving flexible extrusion of the carton and horizontal rotational pushing. When the raw material to be printed is too light, the electric push rods on the inner side of the two pairs of lifting shafts on the lifting support plate extend and retract, driving the U-shaped bracket on the push end to rise and fall stably. The U-shaped bracket drives multiple negative pressure adsorption tubes on it to rise and fall stably, thus squeezing the negative pressure adsorption tubes into contact with the raw material. The negative pressure pump on the U-shaped bracket operates, causing the air inside the diversion adsorption tube, negative pressure hose, and negative pressure adsorption tube to be discharged, thereby adsorbing and fixing the raw material on multiple negative pressure adsorption tubes. The raw material is then transported to the belt conveyor by a pair of horizontal electric guide rails. In summary, the process involves placing the raw material cartons on the placement platform. Based on the carton's height, the lifting screw module adjusts the height of the lifting support plate and concave support block to accommodate the extrusion rollers. The feeding drive motor, via the feeding gear set, rotates the extrusion drive shaft, causing the extrusion rollers to rotate accordingly. The arc-shaped extrusion blocks on their surfaces flexibly press the carton against the telescopic spring column, pushing it horizontally. For lightweight printing materials, the lifting and transporting electric push rod lowers the U-shaped support, bringing the negative pressure adsorption tube into contact with the material surface. After the negative pressure pump starts, air is drawn through the diversion adsorption tube and negative pressure hose to adsorb and fix the material. Then, a horizontal electric guide rail transfers it to a belt conveyor. The entire system is controlled by a centralized control panel, allowing for efficient and adjustable feeding operations via the horizontal electric guide rail and the lifting and transporting electric push rod.

[0021] 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.
