Description

TECHNICAL FIELD

[0001] The present application relates to the packaging box processing technical field, specifically to a packaging box processing device and packaging box processing technology. BACKGROUND

[0002] The packaging box is a box body for packaging products, which is used for single packaging of products to prevent the products from being damaged due to collision during handling and transportation, and to improve the grade of the products and make the products more elegant. The commonly seen packaging boxes on the market are made of various materials. Since paper material has the advantages of light weight, flexible folding, convenient printing decoration, and economic and environmental protection, the paper packaging box is one of the most commonly used packaging boxes. The paper material needs to go through multiple processes such as cutting, printing, indentation and folding assembly to be processed into a packaging box. Therefore, a rotating processing device is needed for paper packaging box production and processing.

[0003] The packaging box paper indentation device is a kind of packaging box processing device, which is used to press a notch on the position of the paper that needs to be folded, so as to facilitate the folding of the paperboard in the subsequent process, so that the paperboard forms a packaging box. The indentation device mainly consists of a driving assembly, a protruding strip and two pressing plates. The protruding strip is fixed to the inner side of one of the pressing plates. The paperboard is placed between the two pressing plates. The driving assembly drives the pressing plates to extrude the paperboard, so that the protruding strip presses a notch on the paperboard. The paperboard with the notch is folded along the notch.

[0004] Although the existing indentation device meets the user's use demand to a certain extent, it still has some defects in use. The specific problems are as follows. The local paperboard is prone to bending deformation under pressure. During the closing process of the two pressing plates, the notch first extrudes the paperboard before the pressing plates extrude the paperboard. The local surface of the paperboard is pressed, which causes the paperboard to bend and deform. Although the subsequent pressing plate can extrude the paperboard to restore the flatness, the deformed paperboard is forced to be pressed flat, which is prone to wrinkles, affecting the quality and appearance of the paperboard. In addition, the wrinkled paperboard is not convenient for printing, which will adversely affect the production of the packaging box. SUMMARY

[0005] The present application provides a packaging box processing device and packaging box processing technology, which can effectively solve the problems raised in the background art.

[0006] To achieve the above purpose, the present application provides the following technical scheme: a packaging box processing device, comprising a mounting frame, a notch mechanism fixedly connected to the top of the mounting frame, a feeding mechanism fixedly connected to one side of the mounting frame, edge cutting mechanisms installed on both sides of the notch mechanism, and a pushing mechanism installed at the bottom of the feeding mechanism.

[0007] The indentation mechanism comprises an indentation strip, a hydraulic rod for driving the indentation strip, a transmission push rod and a hydraulic cylinder, and a long bolt for locking the indentation strip;

[0008] The trimming mechanism comprises a limiting cylinder, a hose for connecting the limiting cylinder and the hydraulic oil cylinder, a piston column, a second spring for resetting the piston column, and a spring telescopic rod for pressing the paperboard and a pressing plate;

[0009] The feeding mechanism comprises a limiting frame for limiting the paperboard, a pressing plate for pressing the paperboard, a driving motor and a feeding roller for conveying the paperboard;

[0010] The pushing mechanism comprises a first pushing assembly and a second pushing assembly, and a servo motor, a half gear and a balance gear for driving and balancing the two assemblies respectively.

[0011] Compared with the prior art, the present application has the following advantages:

[0012] Firstly, after the paperboard is clamped and fixed by the pressing plate and the placing plate, the pressure in the pressing plate is increased or decreased by the extension or retraction of the hydraulic cylinder, the indentation strip is extended or retracted, and the indentation processing of the paperboard is realized.

[0013] The indentation strip can be selected according to the required length and shape of the indentation, and the unselected indentation strip is fixed to the pressing plate by the long bolt.

[0014] The hydraulic rod can drive the fixed cylinder and the piston push rod to move during extension, and the hydraulic oil in the hydraulic oil cylinder is pressurized by the piston push rod to drive the trimming mechanism.

[0015] Secondly, the pressing plate and the cutter are driven by the hydraulic rod and the piston column respectively, so that the paperboard is clamped and fixed by the pressing plate and the placing plate and is cut by the cutter at the same time.

[0016] The pressing plate presses the edge of the paperboard to be cut during cutting, avoids the edge of the paperboard from being raised to cause the cutter to press the paperboard and deform the paperboard, and makes the edge of the paperboard closely contact with the bearing plate to improve the cutting precision.

[0017] The position adjustment of the two sliding blocks is achieved by rotating the bidirectional screw rod, which facilitates the cutting of paperboards of different lengths and cutting different positions of the paperboard according to needs, and improves the use range.

[0018] Thirdly, the position of the limiting frame in the discharging box is adjusted by rotating the threaded column, the paperboard is limited, the feeding position of the paperboard is controlled, the required indentation position of the paperboard is controlled, the indentation position is more accurate, and different length paperboards can be conveniently fed;

[0019] The stacked paperboard is fed by the driving motor and the feeding roller, and under the limitation of the width of the discharging outlet of the discharging box, the feeding mode is single paperboard feeding one by one, which further facilitates the indentation processing of the paperboard.

[0020] Fourthly, the threaded rod is rotated by the forward and reverse motor to adjust the positions of the connecting block, the clamping plate and the bearing plate, the waste cut on the bearing plate is poured down for collection, the cleaning is maintained, and the influence of the waste on subsequent paperboard processing is avoided;

[0021] The processed paperboard is guided by the guide plate, and under the limiting action of the baffle, it always slides to a unified position, which facilitates the neat stacking and storage of the paperboard, and facilitates the packaging and transportation of the paperboard. The position of the baffle fixed in the guide plate can be adjusted, so that the guide assembly can be suitable for guiding paperboards of different widths.

[0022] Fifthly, the first and second pushing assemblies are driven by the two pairs of servo motors and half gears respectively, the second rack is driven to push the paperboard, the position of the paperboard under the pressing plate is controlled, and then the indentation position is adjusted.

[0023] The first rack is popped out by the elastic force, the processed paperboard is pushed out for unloading, the first and second pushing assemblies are used in combination, the automation degree of the device is greatly improved, the processing efficiency is improved, manual position adjustment and feeding and unloading of the paperboard are avoided, and the safety of the packaging box production and processing is improved.
