Description

Technical Field

[0001] The present invention relates to the technical field of indentation devices, and particularly to a positioning indentation device for processing packaging cartons and its usage method. Background Art

[0002] An indentation device is a common device in the processing of packaging cartons, mainly used to press an indentation line on cardboard for subsequent folding and forming. Its core operation is to form a mark at a specific position on the cardboard through the relative movement of mechanical components, including extrusion or sliding.

[0003] Traditional indentation devices usually use fixed baffles or manual adjustment of the cardboard position, and cannot automatically adjust and fix the indentation position according to the change of cardboard size, which easily leads to indentation deviation or asymmetry. It is difficult to achieve multi-angle indentation of cardboard, and it is necessary to manually flip the cardboard or replace the mold, resulting in low efficiency and large errors of the indentation device. At the same time, cardboard with indentation defects needs to be manually detected and removed, and the high missed inspection rate and untimely sorting may lead to defective products flowing into the next process.

[0004] Therefore, in view of the problem that the above-mentioned indentation device cannot automatically adjust and fix the indentation position according to the change of cardboard size, which easily leads to indentation deviation or asymmetry, and cardboard with indentation defects also needs to be manually detected and removed, resulting in a high missed inspection rate, a positioning indentation device for processing packaging cartons and its usage method can be designed. Summary of the Invention

At the center of the upper end of the supporting bottom plate, on one side of the discharge end of the first belt conveyor, a stable material conveying mechanism for transporting and positioning the cardboard to be processed is installed. A bottom adjusting mechanism for rotating and lifting and adjusting the position of the cardboard to be processed is installed at the lower end of the stable material conveying mechanism, and the bottom of the bottom adjusting mechanism is fixed on the supporting bottom plate. On the side of the stable material conveying mechanism away from the first belt conveyor, a second belt conveyor for conveying the cardboard after indentation is installed. A positioning and indentation mechanism is installed at the upper end of the stable material conveying mechanism. On one side of the adjacent ends of the first belt conveyor and the second belt conveyor, a blanking inclined plate for recycling and conveying the defective products with indentation defects is installed. A third belt conveyor is installed at the upper end of the supporting bottom plate and located below the blanking inclined plate. The inside of the stable material conveying mechanism includes a processing table on one side of the discharge end of the first belt conveyor. On both sides of the upper end of the processing table, gantry support frames are fixedly connected. A protective control frame plate is installed at the lower end of the gantry support frame. A servo motor is installed at one end of the outer side of the protective control frame plate, and an adjusting lead screw is installed at the output end of the servo motor.

[0007] Furthermore, a lead screw slider is threadedly connected to the outside of the adjusting lead screw.

Before rotation, the cardboard needs to be released by the suction cup, and after rotation in place, it is adsorbed and fixed again; Step 4: The second cylinder on the support frame plate extends downward, so that the positioning pressure rod at the lower end of the moving side plate contacts the edge of the cardboard, pressing and positioning the two side edges of the cardboard to be processed to ensure the accuracy of the indentation position, and the distance between the two positioning pressure rods can be adjusted by the second bidirectional adjustment cylinder to adapt to cardboard of different sizes; Step 5: The first bidirectional adjustment cylinder drives the pushing plate to move along the length direction of the cardboard, so that the indentation knife at the lower end of the indentation device presses a preset trace on the cardboard surface; Step 6: The cardboard after indentation is adsorbed by the suction cup, start the servo motor to drive the adjusting screw rod to move, so that the screw rod slider drives the cardboard on the suction cup to move. When it moves to the second belt conveyor, release the adsorption, and it is conveyed by the second belt conveyor to enter the subsequent process; Step 7: If indentation defects are detected, including fracture and position deviation, start the rotating motor to drive the processing table to rotate, so that the discharging port of the processing table is located above the blanking inclined plate.

The positioning indentation mechanism can press and fix the cardboard while adjusting the indentation position to prevent certain errors during the processing. The qualified cardboard with indentation completed can be conveyed to the subsequent process through the second belt conveyor, and the defective products with defective indentation can be recycled and conveyed through the third belt conveyor, achieving the effects of rapid processing and sorting.
