Technical Field

[0001] This utility model relates to the technical field of paper box forming equipment, and in particular to the pre-pressing device of rapid paper box forming equipment. Background Technology

[0002] With the development of commerce, the use of cardboard boxes for product packaging is increasing. Before being folded from cardboard, these boxes often require printing. To facilitate subsequent processing, pre-pressing is necessary before printing. Existing technology publication CN214522250U discloses a pre-pressing device for cardboard box printing, comprising a first housing with symmetrically arranged support legs at its bottom, a second housing fixed above the first housing, a positioning rod inside the second housing, sliding blocks symmetrically fitted around the positioning rod, a first telescopic rod at the bottom of each symmetrically arranged sliding block, and a connecting housing at the output end of the symmetrically arranged first telescopic rod. The connecting housing contains a rotating shaft, and the rotating shaft has indentation wheels around its outer periphery. However, this device can only perform one flattening operation, resulting in poor flattening effect and making it inconvenient for flattening cardboard boxes of different thicknesses, thus limiting its applicability. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pre-pressing device for a rapid prototyping equipment for paper boxes, which can adjust the pressing position according to the paper thickness, facilitate multiple pressing of the paper box, and improve the pressing efficiency and pressing effect.

[0004] The pre-pressing device of this utility model for rapid prototyping equipment for paper boxes includes a worktable, multiple support legs, a conveying and flattening component, a creasing component, a secondary flattening component, and a limiting and guiding component. Support legs are fixedly installed at the four corners of the bottom of the worktable. The conveying and flattening component is installed on the right side of the worktable, and the creasing component is installed in the middle of the top of the worktable. The secondary flattening component is installed on the left side of the top of the worktable. The conveying and flattening component can adjust the flattening position according to the paper thickness, which facilitates the function of flattening the paper box multiple times, thereby making the flattening efficiency higher and the flattening effect better. It is convenient to flatten paper boxes of different thicknesses. The creasing component can creasing, and the limiting and guiding component can position the paperboard to prevent deviation during the creasing process and prevent the paperboard from getting stuck on the creasing edge. At the same time, the secondary flattening component can pre-press the creasing paperboard again to make the paperboard flat.

[0005] Preferably, the conveying and flattening component includes multiple conveying rollers, a support frame, multiple electric telescopic rods, an adjusting plate, multiple pressure rollers, multiple drive shafts, a mounting frame, a double-position sprocket, multiple drive wheels, and a drive motor. A conveying trough is provided at the right end of the worktable, and multiple conveying rollers are rotatably installed within the conveying trough. The support frame is installed at both the front and rear ends of the right side of the worktable. Multiple electric telescopic rods are installed at the top of the support frame, and adjusting plates are installed at the telescopic ends of the electric telescopic rods. Multiple pressure rollers are rotatably installed at the bottom of the adjusting plates. An adjusting groove is provided at the front end of the support frame, and a drive shaft is installed through the adjusting groove at the front input end of the pressure rollers.

Drive wheels are installed at the front ends of the left and right drive shafts. The double-position sprocket and the drive wheels are connected by a drive chain. Starting the drive motor rotates the double-position sprocket, which in turn drives multiple drive shafts to rotate synchronously via the drive chain and drive wheels. The drive shafts drive the pressure rollers to rotate, placing the cardboard between the conveyor rollers and the pressure rollers. The pressure rollers and conveyor rollers then perform a leveling and pressing action, facilitating multiple flattening operations on the cardboard box, resulting in higher flattening efficiency and better flattening effect. Activating the electric telescopic rod pushes the adjusting plate downwards, adjusting the distance between the pressure rollers and the conveyor rollers, facilitating the flattening of cardboard boxes of different thicknesses.

[0006] Preferably, it also includes multiple limiting plates and multiple guide rods. Limiting plates are installed at the four corners of the adjusting plate and are slidably installed on the outer walls of the left and right sides of the support frame. Multiple guide rods are evenly installed on the top of the adjusting plate and are slidably installed on the top of the support frame.

A second pressure roller is installed on the left side of the bottom of the mounting plate. Activating the second electric telescopic rod pushes the mounting plate downward, causing the creasing wheel to contact the cardboard and perform a pre-pressing action on the cardboard. When the cardboard moves, it drives the second pressure roller to rotate, preventing the cardboard from getting stuck on the creasing wheel and optimizing the processing effect. Activating the adjusting motor drives the threaded rod to rotate, allowing the movable block to slide on the transverse slide bar, which facilitates the adjustment of the distance between the creasing wheels and increases the applicability.

[0008] Preferably, the secondary flattening component includes an adjusting plate, multiple third electric telescopic rods, and a pressing plate. The flattening frame is installed on the top left side of the workbench, and a support plate is installed at the bottom of the flattening frame.
