Description

Technical Field

[0001] The utility model relates to the technical field of paper box processing, in particular to a full-automatic die-cutting machine capable of quickly cutting paper boxes. Background Art

[0002] Carton die-cutting is a processing method that uses a die-cutting machine to cut cardboard or paper into specific shapes and sizes to make various cartons or cardboard products. This processing method can be used to produce various types of boxes such as packaging boxes, gift boxes, document boxes, etc.

[0003] The U-shaped tube and the dust removal joint are provided with a U-shaped tube and a dust removal joint. When the cutting knife tends to the carton inside the notch of the processing table, the pressure rod drives the piston to squeeze downward on the right side of the U-shaped tube, and the volume inside the U-shaped tube decreases and the pressure increases. The air inside the U-shaped tube moves from the left end of the U-shaped tube to the inside of the corresponding air guide tube. The air entering the air guide tube enters the dust removal joint. Then the air inside the dust removal joint sprays the upper wall of the notch of the processing table from the left outlet, and the dust on the surface of the carton is blown to the inside of the chip removal hole on the right side of the notch of the processing table. The dust entering the inclined surface of the chip removal hole falls along the inclined surface into the slot of the recovery box on the right side below the processing table, which plays a role in cleaning the dust on the surface of the carton and improves the quality of the processed carton.

[0004] Based on the above patent, the air inside the dust removal joint is sprayed from the left outlet onto the upper wall of the paper box in the recess of the processing table, and the dust on the surface of the paper box is blown toward the inside of the chip removal hole on the right side of the recess of the processing table. The dust entering the inclined surface of the chip removal hole falls along the inclined surface into the groove of the recovery box on the right side below the processing table, thereby cleaning the dust on the surface of the paper box. However, the position of the dust removal joint in the above device is fixed, and therefore the range of the above effect is limited, resulting in poor cleaning effect of the device and a decrease in the quality of the paper box. Utility Model Content

[0009] Furthermore, a dust removal nozzle is fixedly connected to the right end of the first transfer rod.

[0010] Furthermore, the compressed air assembly includes a connecting rod slidably connected to the right end of the pressure plate and a U-shaped tube fixedly connected to the bottom end of the dust removal nozzle. A piston is slidably connected to the right inner wall of the U-shaped tube, and the top of the piston is fixedly connected to the bottom end of the connecting rod.

[0016] The U-shaped tube is moved by the first transfer rod and the second transfer rod is lifted up, and the slider is moved forward with the second transfer rod. The connecting rod pushes the piston downward while the connecting rod moves forward, so that the volume in the U-shaped tube is reduced, the pressure is increased, and the air in the U-shaped tube is squeezed and discharged into the dust removal nozzle. The discharged airflow will synchronously blow the dust on the surface of the paper box into the waste box on the right side with the movement of the dust removal nozzle. The dust will float on the dust filter net and adhere to it when entering the waste box, and pass through the pressure plate The second transfer rod drives the first connecting rod to rotate downward, and drives the second connecting rod to move downward to push the slider backward, causing the dust removal nozzle to move backward with the U-shaped tube, and the connecting rod moves upward while moving backward, and drives the piston to be lifted, so that the internal space of the U-shaped tube increases, the pressure decreases, and the dust removal nozzle generates an adsorption airflow, and in the process of the dust removal nozzle moving, the die-cut paper scraps are sucked into the waste box on the left and fall into the cavity of the waste box. The above can realize the movement of the dust removal nozzle when cleaning dust or collecting paper scraps, thereby increasing the effect and range, improving the cleaning efficiency, and thus improving the quality of the paper box.

When the pressure plate 5 moves downward, the connecting plate 7 and the connecting rod 12 move downward synchronously. When the connecting plate 7 moves downward, the rack 8 is pushed downward, and the gear 11 meshing with it rotates, so that the second transfer rod 19 drives the first connecting rod 15 to lift up, and then drives the second connecting rod 16 to lift up and slide the slider 18 forward, and then moves the dust removal nozzle 9 forward through the first transfer rod 17, the hydraulic rod 4 is recovered to drive the pressure plate 5 to move upward, and at the same time, the rack 8 moves upward to reverse the gear 11, so that the second transfer rod 19 drives the first connecting rod 15 to rotate downward, and drives the second connecting rod 16 to move downward to push the slider 18 to move backward, causing the dust removal nozzle 9 to move backward.
