Description

Technical Field

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

[0002] In logistics, transportation, and product packaging, corrugated boxes have become one of the most widely used packaging containers due to their advantages of being lightweight, high-strength, and recyclable. The creasing process is the core step in corrugated box forming—by using creasing wheels to press precise creases on the surface of the corrugated cardboard, it is possible to ensure that the corners of the box are neat and the joints are tight when folding and forming the box later, and to avoid problems such as crease breakage and folding misalignment, which directly affect the load-bearing capacity and appearance quality of the box.

[0003] Most creasing rollers in corrugated cardboard boxes are connected to the frame via fixed brackets, allowing only preset positions for creasing needs of a single box size. They cannot be flexibly adjusted according to changes in cardboard size or the number of creasing cycles. A few adjustable models require manual removal of fixing bolts, moving the bracket, and then re-tightening, which is not only cumbersome but also makes it difficult to guarantee the parallelism and positioning accuracy of the creasing rollers after adjustment. This results in poor creasing accuracy, inconsistent box forming quality, and inconsistent creasing performance for corrugated cardboard boxes of different sizes and sizes. The spacing and position of the creases vary, and the thickness of 3-11 layer corrugated cardboard differs, requiring the crease rollers to adapt to different crease depth requirements. Existing devices are inconvenient to adjust the position of the crease rollers. If they are forcibly adapted to different cardboard specifications, problems such as crease position deviation and uneven crease depth will easily occur. If the crease is too shallow, the cardboard will spring back when folded, resulting in gaps. If the crease is too deep, it will crush the corrugated core paper, reducing the strength of the carton. The device has low adaptability to multiple specifications and poor production changeover efficiency. Therefore, this utility model proposes a corrugated carton forming device to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a corrugated cardboard box forming device, which solves the problem of inconvenient position adjustment of the creasing wheel in the existing creasing mechanism.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a corrugated cardboard box forming device, including a fixed frame, support legs installed at the four corners of the bottom of the fixed frame, a conveying roller installed on the inner side of the fixed frame, an mounting frame installed at the top of the fixed frame, connecting rods installed on both sides inside the mounting frame, mounting plates symmetrically installed inside the mounting frame, an adjustment mechanism provided below the mounting plates, an indentation wheel installed at the bottom of the adjustment mechanism, a lifting mechanism provided below the mounting frame, and a guide mechanism provided above the conveying roller;

[0006] The adjustment mechanism includes a fixed groove, a movable block, a movable frame, a threaded hole, and a positioning bolt. The fixed groove is opened inside the mounting plate. The movable block is arranged inside the fixed groove. The movable frame is installed on the outside of the movable block. The bottom end of the movable frame is connected to the top end of the indentation wheel. A threaded hole is opened through one side of the movable frame. A positioning bolt is arranged through the threaded hole. A length scale is provided on one side of the mounting plate.

[0007] A further improvement is that the cross-section of the fixed groove is larger than the cross-section of the movable block, and the fixed groove and the movable block form a sliding structure.

[0008] A further improvement is made in that: the lifting mechanism includes a cylinder, a guide hole and a guide rod, the cylinder is installed on the top of the fixed frame, the top of the cylinder is connected to the bottom of the mounting frame, the guide hole is opened through at the corner of the mounting frame, the guide rod is provided inside the guide hole, and the bottom of the guide rod is connected to the top of the fixed frame.

[0009] A further improvement is that four guide rods are provided above the fixing frame, and the four guide rods are symmetrically distributed about the central axis of the fixing frame.

[0010] A further improvement is that the guiding mechanism includes a side plate, an electric telescopic rod, a guide plate, and a limiting structure. The side plate is installed on the top of the fixed frame, and an electric telescopic rod is installed at one end of the side plate. One end of the electric telescopic rod extends to the inside of the side plate, and a guide plate is installed at one end of the electric telescopic rod.

[0011] A further improvement is that the limiting structure includes a limiting hole and a limiting rod. The limiting hole is opened through both ends of the side plate, and the limiting rod is installed through the inside of the limiting hole. One end of the limiting rod is connected to one end of the guide plate.

[0012] The beneficial effects of this utility model are as follows: By providing an adjustment mechanism below the mounting plate, the distance between the two creasing rollers can be adjusted through the cooperation of the fixing groove, movable block, movable frame, threaded hole, and positioning bolt of the adjustment mechanism. This allows for flexible adaptation to the creasing requirements of corrugated cardboard of different specifications. The position of the creasing rollers can be adjusted without disassembling parts, significantly shortening production changeover time. It can accurately calibrate the creasing rollers, avoiding positional deviation and parallelism error, ensuring uniform creasing depth, preventing crushing of the corrugated core paper or crease rebound, improving the quality of carton forming, and reducing interference and wear between the creasing rollers and other components. This extends the equipment's lifespan and reduces maintenance costs. By installing a guiding mechanism above the conveyor rollers, the interaction between the guide mechanism's side plates, electric telescopic rods, guide plates, limiting holes, and limiting rods can correct offsets and tilts in the cardboard transmission in real time, ensuring precise movement along the preset path. This avoids misalignment of indentations and breakage of creases due to positional deviations, ensuring neat edges and corners of cartons. It can flexibly adapt to different cardboard specifications without cumbersome manual adjustments, shortening production changeover time. At the same time, it stabilizes the cardboard's posture, laying the foundation for subsequent folding and gluing processes, reducing scrap rates, and improving the device's practicality and production efficiency.
