Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing equipment, and particularly relates to a printing positioning and conveying device for corrugated cardboard boxes. Background Art

[0002] Corrugated cardboard boxes are one of the most widely used and common packaging materials in the world, and are widely used in various fields, such as manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods. Especially in transportation packaging, corrugated cardboard boxes have become one of the most common packaging methods.

[0003] In order to improve the aesthetics of the use of corrugated cardboard boxes and the convenience of identifying and explaining the internal packaged products, printing is usually carried out on the surface of corrugated cardboard. During the printing process of corrugated cardboard, a conveying device is equipped to convey the corrugated cardboard. However, in order to improve the accuracy of the printing position of the printed pattern on the corrugated cardboard, a positioning device is usually set in the conveying device to ensure that the printed pattern corresponds to the preset printing area on the corrugated cardboard.

[0004] For example, Chinese Patent Application No. (CN202323019924.X) discloses a printing positioning device for corrugated cardboard, including a conveyor. A positioning mechanism is arranged on one side of the upper end of the conveyor. The positioning mechanism includes two arc-shaped positioning plates and a rotating shaft. Two fixing plates are fixedly installed on one side of the arc-shaped positioning plate. The fixing plates are in an L-shaped structure. A connecting plate is fixedly connected between the two fixing plates. This application guides and positions the corrugated cardboard along the direction perpendicular to its moving direction through the arranged positioning mechanism, and the adjustment is convenient. However, this application does not position the corrugated cardboard along its moving direction. When the corrugated cardboard moves on the conveyor, there must be differences in the intervals between adjacent corrugated cardboard, which will lead to differences in the time intervals for entering the printing equipment and the printing time intervals of the printing equipment for the corrugated cardboard, and it is easy to cause the printed pattern to shift in the moving direction of the corrugated cardboard, affecting the printing effect.

[0081] A second guiding plate 51, which is slidably connected to the feeding platform 30 along the direction perpendicular to the movement direction of the corrugated cardboard;

[0082] A second slider 52, which is slidably connected to the feeding platform 30 and is connected to the second guiding plate 51;

[0083] A second driving member 53, which is installed on the feeding platform 30 and is used to drive the second slider 52 to drive the second guiding plate 51 to slide on the feeding platform 30;

[0084] Among them, the feeding platform 30 is provided with a second sliding groove 54 adapted to the second slider 52;

[0087] The second driving member 53 can be a cylinder.

[0088] As can be seen from this embodiment, through the first introduction plate 50 and the second introduction plate 51, it is convenient to position the corrugated cardboard box after it enters the feeding platform 30, ensuring the position accuracy of the corrugated cardboard box on the feeding platform 30. Moreover, the second driving member 53 drives the second introduction plate 51 to slide, capable of clamping the corrugated cardboard box entering the feeding platform, thereby ensuring the accuracy of the position of the corrugated cardboard box in the direction perpendicular to its moving direction, and avoiding deviation due to the conveying mechanism 2 entering the feeding platform.

[0089] Embodiment 5:

[0090] This embodiment provides a printing, conveying and positioning device for corrugated cardboard boxes. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The second positioning mechanism 5 further includes:

[0091] A correction assembly 55, installed in the material passing channel 32 and used for correcting the position of the corrugated cardboard box in its moving direction.

[0092] As can be seen from this embodiment, through the correction assembly 55, cooperating with the first introduction plate 50, the corrugated cardboard box can be clamped, thereby ensuring the accuracy of the position of the corrugated cardboard box in its moving direction. Cooperating with the second introduction plate 51 and the pushing assembly 33, precise positioning is carried out before the corrugated cardboard box enters the printing mechanism, so that the intervals of multiple corrugated cardboard boxes in terms of time and position are the same, ensuring the accuracy of printing and improving the printing effect.

[0093] Embodiment 6:

[0094] This embodiment provides a printing, conveying and positioning device for corrugated cardboard boxes. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The correction assembly 55 includes:

[0095] A flipping plate 550, hingedly connected to the bottom end of the baffle 31;

[0096] Magnetic attraction plates 551, installed at both ends of the flipping plate 550;

[0097] Magnets 552, installed on the bracket 1 and located on both sides of the flipping plate 550, and arranged corresponding to the magnetic attraction plates 551;

[0098] Among them, the magnetic attraction plates 551 can be made of a metal material that can be adsorbed by the magnets 552. At the same time, the magnetic attraction between the magnetic attraction plates 551 and the magnets 552 can push the corrugated cardboard box, and can be separated under the push of the pushing assembly 33.

[0099] Furthermore, when the magnetic attraction plate 551 is attracted to the magnet 552, the gap between the flip plate 550 and the feeding platform should be smaller than the thickness of the corrugated carton board, so as to ensure the correction of the corrugated carton board.

[0100] It can be seen from the present embodiment that the flip plate 550 is used to perform fine-tuning on the corrugated cardboard board on the feeding platform before it enters the printing mechanism to ensure printing accuracy. Specifically, due to the setting of the baffle 31 and the first introduction plate 50, the offset of the corrugated cardboard board in its moving direction is usually small, and the adsorption of the magnetic plate 551 and the magnet 552 can eliminate the offset to ensure the accuracy of the position of the corrugated cardboard board, and the adsorption between the magnetic plate 551 and the magnet 552 can be pushed open by the pushing component 33, so as not to affect the corrugated cardboard board entering the printing component.
