Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a rapid registration device for packaging carton printing includes a fixed frame 1. A conveyor belt 20 is installed in the middle of the fixed frame 1. Mounting blocks 2 are symmetrically and slidably installed on both sides of the fixed frame 1. A rotating shaft 3 is rotatably installed between the two mounting blocks 2 through a bearing. A motor 4 is fixedly installed on one side of one of the mounting blocks 2. The output end of the motor 4 is fixedly connected to the end of the rotating shaft 3. A rotating cylinder 5 is installed in the middle of the rotating shaft 3. Rounded corner plates 6 are fixedly installed on the outer circle of the rotating cylinder 5 in an annular array with the central axis of the rotating cylinder 5 as the axis. The rounded corner plates 6 can squeeze the conveyed packaging cartons. Pushing plates 7 are slidably installed at both positions on both sides of the fixed frame 1. The pushing plates 7 move as the mounting blocks 2 move. Place the packaging carton on the conveyor belt 20. The conveyor belt 20 operates to convey the packaging carton. The motor 4 operates to drive the rotating cylinder 5 to rotate. The rounded corner plates 6 on the outer circle of the rotating cylinder 5 will contact and squeeze the packaging carton. Under the squeezing of the rounded corner plates 6 on the packaging carton, the mounting blocks 2 will be driven to rise, which can drive the two pushing plates 7 to approach each other, for centering the packaging carton and realizing rapid registration of printing. When centering packaging cartons with different thicknesses, the rounded corner plates 6 can still squeeze the packaging cartons, and the mounting blocks 2 can be controlled to slide and rise along the trajectory of the limiting rods 8, which can also drive the two pushing plates 7 to approach each other, realizing centering of packaging cartons with different thicknesses.

[0022] As Figures 1 to 5As shown in the figure, limiting rods 8 are symmetrically and fixedly installed on both sides of the fixing frame 1. The mounting block 2 is slidably installed between the two limiting rods 8. A first return spring 19 is sleeved on the outer side of the top end of the limiting rod 8. One end of the first return spring 19 is fixedly connected to the top of the mounting block 2, and the other end of the first return spring 19 is fixedly connected to the fixing frame 1. One side of the mounting block 2 is rotatably installed with a connecting rod 9 through a pin. Corresponding to the horizontal position of the limiting rod 8 on both sides of the fixing frame 1, sliding holes 10 are symmetrically opened. A sliding rod 11 is slidably installed inside the sliding hole 10. The push plate 7 is fixedly installed at the end between the two sliding rods 11. The end of the connecting rod 9 away from the mounting block 2 is rotatably connected to the end of the sliding rod 11 away from the push plate 7 through a pin.

[0023] When the rounded plate 6 squeezes the packaging carton, it can drive the mounting block 2 indirectly connected to the rounded plate 6 to slide and rise along the track of the limiting rod 8. Through the connection between the mounting block 2 and the sliding rod 11 by the connecting rod 9, the sliding rod 11 will be driven to slide inside the sliding hole 10 to control the two push plates 7 to approach each other.

[0024] As Figures 1 to 5 shown in the figure, the sliding rod 11 includes a mounting rod 12 and a sleeve 13. The mounting rod 12 is slidably installed inside the sliding hole 10. The end of the connecting rod 9 away from the mounting block 2 is rotatably connected to one end of the sleeve 13 through a pin. The mounting rod 12 is slidably installed inside the sleeve 13. A buffer spring 14 is fixedly installed at the end of the mounting rod 12 away from the push plate 7. The other end of the buffer spring 14 is fixedly connected to the inner wall of the end of the sleeve 13.

[0025] When controlling the two push plates 7 to approach each other to center the packaging carton, the mounting rod 12 can be driven to slide inside the sleeve 13 by the extrusion on both sides of the packaging carton. The buffer spring 14 can prevent the push plate 7 from over-extruding the packaging carton.

[0026] As Figures 1 to 5 shown in the figure, limiting blocks 15 are symmetrically and fixedly installed on the outer side of the rotating shaft 3. Limiting grooves 16 are opened at the positions corresponding to the limiting blocks 15 inside the rotating cylinder 5. The limiting blocks 15 are slidably connected to the limiting grooves 16.

[0027] When the two push plates 7 centrally extrude the packaging carton, the rounded plate 6 is in a state of constantly squeezing the packaging carton. During this process, the rotating cylinder 5 will be driven to slide along the outer side of the rotating shaft 3 through the extrusion friction force between the rounded plate 6 and the packaging carton to prevent the rounded plate 6 from wearing the packaging carton.

[0028] As Figures 1 to 5 shown in the figure, second return springs 17 are symmetrically sleeved on the outer sides of both ends of the rotating shaft 3. One end of the second return spring 17 is fixedly connected to the end of the rotating shaft 3, and the other end of the second return spring 17 is in indirect contact with the end of the rotating cylinder 5.

[0029] When the rotary drum 5 slides along the outer side of the rotating shaft 3, one of the second return springs 17 will be in a compressed state. When the packaging carton is conveyed without being squeezed by the rounded corner plate 6, the rotary drum 5 can be moved to the middle position of the rotating shaft 3 by the pushing of the second return spring 17 on the rotary drum 5, preventing excessive deviation of the rotary drum 5.

[0030] As Figures 1 to 5 shown, an installation ring 18 is fixedly installed at one end of the second return spring 17 away from the rotating shaft 3. The installation ring 18 is slidably installed on the outer side of the rotary drum 5, and the side of the installation ring 18 away from the second return spring 17 is in contact with the end of the rotary drum 5.

[0031] It is convenient to install and disassemble the rotary drum 5 by installing the end of the second return spring 17 on the installation ring 18.

[0032] The utility model provides a device for quickly aligning printing of a packaging carton. The specific working principle is as follows:

[0033] When the device is in use, the packaging carton is placed on the conveyor belt 20. The conveyor belt 20 operates to convey the packaging carton. The motor 4 operates to drive the rotating shaft 3 to rotate. The limit between the limit block 15 and the limit groove 16 drives the rotary drum 5 to rotate synchronously. The rounded corner plate 6 on the outer circle of the rotary drum 5 contacts and squeezes the packaging carton. Under the squeezing of the rounded corner plate 6 on the packaging carton, the mounting block 2 indirectly connected to the rounded corner plate 6 slides and rises along the track of the limit rod 8. The connection between the mounting block 2 and the sliding rod 11 through the connecting rod 9 drives the sliding rod 11 to slide inside the sliding hole 10, driving the two push plates 7 to approach each other for centering the packaging carton and realizing quick alignment of printing. During the process of the rounded corner plate 6 squeezing the packaging carton, the rotary drum 5 continues to rotate for continuous conveyance of the packaging carton.

[0034] Although the embodiments of the utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the appended claims and their equivalents.
