Description

Technical Field

[0001] This invention relates to the field of folding box packaging machine technology, and in particular to a fully automatic folding box packaging machine and its working method. Background Technology

[0002] In the printing workshop, after the printed materials are produced (finished products), they need to be packaged or boxed. Some printed materials are bundled before being boxed, while others are boxed directly. Under normal circumstances, the boxing process requires manual loading of the printed materials into boxes according to the orders. If sub-boxing is involved, manual repacking is also required. After manual boxing, the materials are transported to labeling and packaging equipment for labeling and securing. This boxing method involves a lot of manual intervention, which can easily lead to errors or labeling mistakes, resulting in significant cost losses. It also places a high labor intensity on the workers. Moreover, during periods of high business volume, additional manpower is needed to complete the boxing task, which can easily lead to cost losses such as missing or incorrect packing.

[0003] Furthermore, due to the specific nature of the products (printed goods), the required packaging box sizes vary depending on the type and specifications. Therefore, cross-shaped cardboard, which is easier to manufacture and more adaptable, is often used, abandoning the traditional corrugated cardboard, which has high production costs and limited packaging capabilities, as well as its associated box-gluing machines. Most cardboard box-forming equipment uses the box-forming mechanism of the box-gluing machine. For example, invention patent application number 202510287537.9 discloses a cardboard box top packaging equipment and method, and invention patent application number 2024116845919 discloses a corrugated cardboard box-forming machine and method, which forms a space inside the cardboard box to complete the box's closing action, thereby completing the material packaging. This is suitable for semi-finished cardboard boxes (the corrugated cardboard has already been glued, but it is not stretched into a box), and requires the corrugated cardboard to have a fixed size. Therefore, it cannot solve the problems of rapid box-forming and automatic box folding of cross-shaped cardboard blanks, nor can it conveniently adjust the box specifications according to the material size. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic folding box packaging machine and its working method, so as to solve the problem of rapid box forming and automatic folding of cross-shaped cardboard blanks, and to realize the problem of convenient adjustment of box specifications according to material size.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fully automatic box folding and packaging machine, comprising: A frame, on which a belt conveyor is mounted, and on the conveyor belt of the belt conveyor are a pair of limiting plates; A feeding mechanism is provided on the frame and adapted to the feed end of the belt conveyor. The feeding mechanism places a cross-shaped cardboard on the conveyor belt and is located between a pair of limiting plates. The cross-shaped cardboard is formed into a box with the opening facing upward. A folding mechanism is provided on the frame and adapted to the discharge end of the belt conveyor. The folding mechanism is provided with a working end that folds the four sides of the box body, so that the box body is formed into a sealed packaging box.

[0006] A further technical solution is as follows: the feeding mechanism includes a storage rack, a picking arm, a negative pressure suction cup, and multiple folding plates. The storage rack is set on the frame and is used to store multiple cross-shaped cardboards. The picking arm is rotatably mounted on the frame and driven by a motor. The negative pressure suction cup is set on the picking arm and is used to pick up the cross-shaped cardboards. The four folding plates are respectively set around the feeding end of the belt conveyor, and the four folding plates are adapted to the four sides of the cross-shaped cardboards.

[0007] A further technical solution is that: the belt conveyor is provided with clearance spaces on both sides for the material handling arm to pass through.

[0008] A further technical solution is as follows: the folding mechanism includes a longitudinal pressure plate, a lateral pressure plate, and a first cylinder. The longitudinal pressure plates are symmetrically arranged and rotatably mounted on the frame, and the two longitudinal pressure plates are located between the two conveyor belts. The longitudinal pressure plates are driven by a motor. The lateral pressure plates are symmetrically arranged and rotatably mounted on both sides of the frame. The two ends of the first cylinder are rotatably connected to the lateral pressure plates and the frame, respectively.

[0009] A further technical solution is that both the longitudinal pressure plate and the lateral pressure plate are arc-shaped plates.

[0010] A further technical solution is: a pressure rod is provided at the outer end of the lateral pressure plate, and the end of the pressure rod is provided with an upwardly curved portion.

[0011] A further technical solution is as follows: a clamping assembly is provided on the frame, the clamping assembly includes a gantry, a second cylinder, a pressure roller and a connecting rod, the gantry is mounted on the frame, the second cylinder is rotatably mounted on the gantry, one end of the connecting rod is rotatably connected to the gantry, the pressure roller is rotatably mounted on the other end of the connecting rod, the power output end of the second cylinder is rotatably connected to the connecting rod, and the pressure roller is adapted to the folding mechanism.

[0012] A further technical solution is: a third cylinder is inclinedly arranged on the gantry frame, and the third cylinder is directed toward the feed end of the folding mechanism.

[0013] The operating procedure for a fully automatic folding box packaging machine is as follows: S1. Paper picking: Place a stack of cross-shaped cardboard on the storage rack of the feeding mechanism. The picking arm uses a negative pressure suction cup to pick up the cross-shaped cardboard between two limiting plates on the conveyor belt. Under the action of multiple folding plates, the cross-shaped cardboard will form a box with the opening facing upward. S2, Feeding: The belt conveyor carries the cross-shaped cardboard forward. Before entering the folding mechanism, the material can be placed into the box by manual labor or a robotic arm. The height of the material shall not exceed the depth of the box. S3, Sealing: The box containing the material moves forward with the conveyor belt to the folding mechanism. The two longitudinal pressure plates work first to fold the two flaps on the longitudinal side of the box together. Then the two lateral pressure plates work to fold the two flaps on the transverse side of the box together to form a packaging box. Finally, the two longitudinal pressure plates are reset and the packaging box continues to move forward. When moving forward, the clamping components can be used to press down the seams of the packaging box; When folding vertically, the third cylinder can be used to eliminate the influence of the folding plate on the vertical end fold of the box in advance; S4. Strapping: A strapping machine is installed at the discharge end of the fully automatic folding box packaging machine to strap the packaging boxes.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a fully automatic folding box packaging machine. When using the feeding mechanism, that is, when picking up and placing the cross-shaped cardboard onto the limiting plate, the machine can achieve a rapid box-forming effect, which is faster than the traditional corrugated cardboard box-forming process. On this basis, the machine has a simple box-forming structure, and the position of the limiting plate and the feeding mechanism can be easily adjusted. It can adapt to the box-forming requirements of cross-shaped cardboard of different specifications and can also meet the packaging needs of printed products of different sizes.

[0015] When sealing the box, the folding mechanism folds the four flaps from all four sides of the cardboard box. After folding, the flaps are automatically pressed together. The process is smooth and fast. The folding mechanism has a simple structure, does not require too many mechanical structures and controls, has low cost, is easy to control, and has high work efficiency.

[0016] After the boxes are formed, the fully automatic folding and packaging machine can work in conjunction with printing equipment and cutting equipment to pack the printed materials into the boxes, achieving automated and efficient production. Then, the folding mechanism closes and presses the boxes to arrange the printed materials and packaging boxes, making it easier to fix the boxes, such as by bundling or sealing, thus improving the adaptability and automation of the equipment.
