Description

Technical Field

[0001] The invention relates to the technical field of packaging box marking, in particular to a full-automatic packaging box marking device. Background Art

[0002] Packing box marking refers to the process of marking and labeling on the surface of packaging boxes or goods. With the continuous development of global trade and the increasing complexity of logistics systems, the rapid and accurate identification, tracking and management of goods have become a crucial link in supply chain management. By marking and labeling on packaging boxes or goods, the identification, tracking and management of goods during transportation, warehousing and management can be achieved. The identification information on the packaging box usually includes product name, quantity, weight, production date, batch number, barcode, QR code, destination, etc.

[0003] The existing marking method usually uses a conveyor belt to transport the packaging box to a designated location, and then prints the mark on the carton through a marking device, which is similar to the marking method recorded in the application number "CN202021629783.7". This marking method mainly uses a marking device to mark it, and usually can only mark one side of the carton. When multiple sides need to be marked, the carton needs to be manually turned over and re-marked. This method is more troublesome. Another method is to use the patent number "CN202010967511.6" in It is recorded that after using a marking device to mark the box, a box flipping mechanism is used to flip the box over, and then the marking device is used to mark multiple surfaces of the box. This marking method is convenient for marking multiple surfaces, but the marking method for the packaging box is to fold the packaging box into a box and then perform the marking operation. The box is hollow in the middle and may collapse during the marking process due to its hollowness, making the marking unclear. In addition, the flipping operation of the hollow packaging box is also easy to bump the packaging box and damage the packaging box. Summary of the invention

[0004] 1. Technical issues to be resolved

[0017] Working principle: open the upper box of the packaging box and point the opening toward the position of the limiting device 6, then place the flip-covered cardboard at the box opening at the bottom and flatly place it on the surface of the conveyor belt 204, then drive the driving wheel 203 to rotate through the motor 202, and the driving wheel 203 drives the driven wheel group 208 to rotate through the transmission belt 207, thereby driving the conveyor belt 204 to move, and the movement of the conveyor belt 204 drives the packaging box to move through the guide plate 206 to automatically adjust the position of the box, and after moving to the position of the limiting device 6, the box is pushed by the push plate 205 and sleeved on the surface of the limiting column 601, and then the first cylinder 4 is started, and the first cylinder 4 drives the second bracket 10 to move downward. When the second bracket 10 moves downward, the toothed rod 7 and the arc-shaped toothed plate 8 begin to contact and mesh with each other, thereby driving the limit device 6 to rotate and move. When it moves to the upward position of the guiding inclined surface 602, the inclined plate 506 just contacts it and the toothed rod 7 is no longer meshed with the arc-shaped toothed plate 8. When it continues to move downward, the carton is slid up to the top of the inside of the moving box 502 through the inclined plate 506. At this time, the toothed rod 7 and the arc-shaped toothed plate 8 are no longer in contact. Then, the second cylinder 501 is started to move the moving block 503 downward, thereby driving the first marking stamp 507 to move downward. At the same time, the connecting rod 504 moves downward and slides through the inclined surface. The inclined surface of block 508 drives the moving plate 509, so that the second marking stamp 510 and the third marking stamp 511 set on the moving plate 509 are moved to the side of the carton and the carton surface of the carton opening flap respectively for marking, and the same operation is performed on the other carton surfaces. After the marking is completed, the moving block 503 is moved upward by the second cylinder 501, thereby driving the first marking stamp 507 to move upward. At the same time, the moving plate 509 moves to the original position under the action of the first spring 513 and the sliding rod 512, and then the first cylinder 4 is started to drive the second bracket 10 to move upward, and at the same time, the fourth cylinder is started to drive the moving rod 902 to move against the square rotating block 90 4. When the moving box 502 moves out of the limiting column 601, the fourth cylinder is started again, thereby driving the moving rod 902 to move and then driving the square rotating block 904 to rotate, so that the position of the guiding slope 602 is directed toward the conveyor belt 11, and the third cylinder 604 is started to drive the sliding plate 607 to move, thereby driving the pushing block 608 to move along the slide groove to push the carton forward onto the conveyor belt 11 and move it to other positions. After that, the sliding plate 607 moves the pushing block 608 to its original position through the action of the second spring 606, and then the fourth cylinder is started to slowly retract the moving rod 902. At this time, the limiting column 601 moves to its original position through the elastic force of the third spring 907.
