Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of printing devices, and particularly relates to a packaging box production device. BACKGROUND

[0002] In the field of packaging printing, circular packaging boxes are widely used in food, cosmetics, gift and other industries due to their beautiful appearance and comfortable feel. After the production and manufacturing of the packaging boxes, they generally need to be printed. In the process of printing the circular packaging boxes, the feeding relies on manual operation, and the workers need to place the packaging boxes one by one into the printing station, which not only has high labor intensity and low production efficiency, but also easily causes positioning deviation of the packaging boxes due to the instability of manual operation, thereby affecting the subsequent printing precision. Moreover, part of the automatic feeding equipment is only suitable for regular square or flat packaging boxes, and it is difficult to automatically grasp, convey and position the arc-shaped outer surface of the circular packaging boxes, and problems such as slipping and deviation are prone to occur.

[0003] Meanwhile, in the printing process, in order to ensure the clarity and position accuracy of printing, the packaging box needs to be fixed. The existing fixing device mainly adopts a simple clamp, and the traditional clamp clamps the two sides of the packaging box through mechanical force, which easily causes deformation of the packaging box due to uneven clamping force, or rotation due to unstable clamping of the arc-shaped surface, thereby causing misalignment of the printed pattern.

[0004] During the production and storage of the packaging box, dust and other impurities are easily attached to the surface. If direct printing is performed, the impurities will cause poor adhesion of the ink, and defects such as blurred pattern, bubbles and peeling will occur, thereby affecting the product quality. After printing is completed, the ink needs to be quickly dried to avoid pattern smearing caused by subsequent processes.

[0067] After the cleaning is completed, the control valves in the vent hole two 19 and the vent pipe 25 are closed, the control valve in the connecting pipe 33 is opened, the air pump 22 continues to work, the gas enters the vent cavity three 21 through the inflation pipe 23, and then enters the air blowing part 32 through the connecting pipe 33, the hydraulic rod two 29 works to adjust the position of the spray head 31 to the appropriate position, then the motor 11 drives the driving plate 9 to rotate, the driving plate 9 drives the temporary storage part 10 to rotate, the temporary storage part 10 drives the hydraulic rod one 8, the expanded fixing assembly and the fixed packaging box 12 to rotate, and the spray head 31 sprays and prints the packaging box 12, and then the printed packaging box 12 is rotated to the position of the air blowing part 32, the gas in the air blowing part 32 is discharged through the drying hole to dry the printing on the packaging box 12;

[0068] Then the air pump 22 stops working, the control valve in the vent pipe 25 is opened, and the hydraulic rod one 8 works to drive the push plate 15 to move away from the motor 11, in the moving process, the push plate 15 extrudes the elastic folding bag 16, the gas in the elastic folding bag 16 enters the vent pipe 25 through the vent hole three 24, and then enters the communication cavity 26 through the vent pipe 25, and finally is discharged from the air outlet hole 27, so that the printing on the surface of the packaging box 12 is dried again, until the push plate 15 is clamped into the slot hole 13.

[0069] After the motor 11 drives the temporary storage part 10 to rotate to the position of the falling hole 40 of the workbench 1, the motor 11 stops working, and the packaging box 12 with the clamping part 37 falls into the discharging box 41 through the falling hole 40, so as to be collected.

[0070] The motor 11 reversely rotates to drive the temporary storage part 10 to return to the initial position.
