Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a cardboard flattening device for cardboard box processing. Background Technology

[0002] Cardboard boxes are widely used in logistics, food, electronics, and pharmaceutical industries. Their flatness directly affects printing quality, stacking stability, and automated packaging efficiency. However, cardboard is susceptible to factors such as humidity and pressure during storage, transportation, or processing, leading to warping and deformation, which makes subsequent processing (such as die-cutting, printing, and gluing) difficult and can even increase scrap rates. Therefore, it is necessary to design a cardboard flattening device for cardboard box processing.

[0003] To this end, patent CN222712984U discloses a cardboard flattening device for cardboard box processing, relating to the field of cardboard processing technology. This cardboard flattening device includes a conveyor table, a flattening assembly, and a preheating assembly. The flattening assembly is located above the conveyor table, and the preheating assembly is located to one side of the flattening assembly. The preheating assembly includes a mounting column, an air outlet box, a hot air blower, a T-shaped pipe, and connecting pipes. The mounting column is fixedly connected to the top of the air outlet box, and two sets of connecting pipes are fixedly connected to the front and rear sides of the air outlet box, respectively, arranged opposite to each other. This invention can preheat the cardboard, softening the fibers and resin in the cardboard, increasing its plasticity, making the cardboard easier to flatten and shape, reducing stress concentration and fiber breakage during the flattening process, reducing scratches and damage to the cardboard surface during flattening, protecting the surface quality of the cardboard, and making the cardboard deform more evenly during processing, thus improving the flattening effect.

[0004] Although the cardboard flattening device for cardboard box processing mentioned above can protect the surface quality of the cardboard during use, the cardboard is flattened on the conveyor belt during the flattening process, and the bottom of the cardboard lacks stable support, resulting in poor flattening effect. Therefore, it is necessary to design a cardboard flattening device for cardboard box processing. Utility Model Content

[0005] The purpose of this invention is to provide a cardboard flattening device for cardboard box processing, which solves the problem that existing cardboard flattening devices for cardboard box processing lack stable support at the bottom of the cardboard during the flattening process, resulting in poor flattening effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cardboard flattening device for cardboard box processing, including a base;

[0007] A conveying structure is provided on one side of the top of the base, and limiting plates are fixed on both sides of the top of the base. A heightening plate is fixed on the side of the top of the base away from the conveying structure.

[0008] A bracket is fixed to the top of the outer base of the heightening plate. A flattening structure is fixed to the inner wall of the top of the bracket. The flattening structure includes an electric push rod fixed to the inner wall of the top of the bracket. A connecting plate is fixed to the bottom of the electric push rod. A heating box is fixed to the bottom of the connecting plate. An electric heating wire is fixed inside the heating box. A guide rod is fixed at the corner position of the top of the electric push rod.

[0009] Furthermore, the conveying structure includes a reserved groove, conveying rollers, anti-slip rubber pads, connecting wheels, a conveying chain, and a drive motor. The reserved groove is opened on one side of the top of the base. Conveying rollers are evenly arranged inside the reserved groove. Anti-slip rubber pads are fixed on the outer side walls of the conveying rollers. The connecting wheels are evenly rotated and connected to the outer wall of one side of the base. The outer side of the connecting wheels is meshed with the conveying chain. The drive motor is fixedly installed on the outer wall of one side of the base.

[0010] Furthermore, both ends of the conveying roller are rotatably connected to the inner wall of the base, and the conveying rollers are evenly distributed inside the reserved groove.

[0011] Furthermore, one end of each conveying roller extends to the outside of the base and is fixedly connected to one side of the connecting wheel, and the output end of the drive motor is fixedly connected to one side of the connecting wheel.

[0012] Furthermore, the limiting plates are symmetrically distributed at both ends of the conveying roller.

[0013] Furthermore, the top ends of the guide rods all extend to the outside of the bracket and are slidably connected to the bracket, and the guide rods are symmetrically distributed on both sides of the electric push rod.

[0014] Furthermore, the heating wire has an "S"-shaped cross-section when viewed from above.

[0015] The advantages of the cardboard flattening device for cardboard box processing provided by this utility model are as follows:

[0016] By incorporating a flattening structure, an electric push rod provides controllable downward pressure, which, combined with a heating box to soften cardboard fibers and eliminate warping, and an "S"-shaped distribution of heating wires to ensure even heat distribution and prevent localized overheating that could damage the cardboard, and a guide rod to ensure vertical movement of the flattening structure to prevent uneven pressure from crushing the cardboard, this device achieves the function of facilitating stable downward pressure on the cardboard, thus improving the working efficiency of the cardboard flattening device in cardboard box processing.

[0017] With its conveying structure, the combined action of conveying rollers and anti-slip rubber pads ensures that the cardboard does not slip or shift during transport, improving flattening accuracy. The evenly spaced conveying rollers provide continuous support for the cardboard, preventing deformation caused by uneven local stress. The drive motor rotates the conveying rollers through the conveying chain and connecting wheels, ensuring continuous and stable transport of the cardboard. This device facilitates the transport of cardboard and improves the convenience and efficiency of the cardboard flattening device for cardboard box processing. Attached Figure Description
