Description

Technical Field

[0001] This utility model relates to the field of labeling and printing technology, and in particular to an integrated machine for pad printing, labeling, and stacking egg cartons. Background Technology

[0002] Egg cartons are packaging boxes used to package eggs. Before the eggs are sold, labels and relevant information need to be affixed to the egg cartons. A search revealed that Chinese utility model patent application CN202320937552.X discloses an automatic egg carton labeling machine, relating to the field of automatic labeling technology. The machine includes a material dispensing mechanism, a conveying mechanism, a labeling machine, and a stacking mechanism. The material dispensing mechanism comprises a feeding rack and a flipping mechanism. The feeding rack has a ramp, and the flipping mechanism is located on the downhill side of the ramp. The conveying mechanism is located below the flipping mechanism and includes a first conveyor belt, an adjustable side plate, and a translation mechanism. The translation mechanism drives the adjustable side plate closer to or further from the fixed side plate. The flipping mechanism is used to absorb egg cartons and place them horizontally onto the conveying mechanism. The labeling machine is located on one side of the conveying mechanism in the conveying direction and is used to automatically label the egg cartons. The stacking mechanism includes a stacking rack and a lifting mechanism. The lifting mechanism is used to push out egg cartons entering the stacking rack and stack them sequentially. This application enables automatic feeding, labeling, and stacking of egg cartons and is adaptable to egg cartons of different sizes, making it more versatile.

[0003] Currently, egg carton labeling and printing equipment on the market is divided into two independent types: egg carton printing machines and egg carton labeling machines. However, both egg carton printing and egg carton labeling require separate feeding and receiving operations. The multiple operating conditions result in a large footprint, and the two feeding and receiving (stacking) operations increase the product scrap rate. When producing in series, an additional product transfer step is required, which is wasteful and inefficient. Existing equipment also has problems such as being only suitable for a single product and requiring dedicated machines for specific purposes. Utility Model Content

[0021] like Figure 1-4As shown, the egg carton pad printing, labeling, and stacking integrated machine includes a feeding assembly 1, a pad printing and sorting section 2, a pad printing machine 3, a flip-sorting label pressing assembly 4, an adhesive label assembly 5, a label feeding assembly 6, and a stacking machine 7 arranged in a straight line. The pad printing and sorting section 2 is connected to the feeding assembly 1, the pad printing machine 3, and the flip-sorting label pressing assembly 4. The adhesive label assembly 5 is connected to the flip-sorting label pressing assembly 4 and the label feeding assembly 6. The stacking machine 7 is connected to the flip-sorting label pressing assembly 4. It can be understood that the egg carton pad printing, labeling, and stacking integrated machine can be divided into two production lines, each equipped with the aforementioned feeding assembly 1, pad printing and sorting section 2, pad printing machine 3, flip-sorting label pressing assembly 4, adhesive label assembly 5, label feeding assembly 6, and stacking machine 7.

[0022] Specifically, the feeding assembly 1 is equipped with a feeding drive motor 8, a rocker arm 9, an eccentric wheel 10, and a vacuum suction cup 11. The eccentric wheel 10 is connected to the feeding drive motor 8 and the rocker arm 9 respectively. The vacuum suction cup is mounted on the rocker arm. When the eccentric wheel 10 rotates, it drives the rocker arm 9 to rise and pick up the product (egg box), and when it descends, it puts the product down. The pad printing sorting section 2 is equipped with a first push block 12, a first reducer 13, and a first servo motor 14. The first reducer 13 is connected to the first push block 12 and the first servo motor 14 respectively.

The stacking machine 7 is used for product collection and stacking.

[0023] During operation, the feeding component 1 uses a vacuum suction cup 11 to separate the egg carton and place it on the push block space of the pad printing sorting section 2. The pad printing sorting section 2 advances one unit per cycle and moves forward one station. When the pad printing machine 3 detects a product, the pad printing machine 3 completes the pad printing pattern. After advancing one unit in the next cycle, the egg carton enters the conveyor line of the flipping sorting and labeling component 4 to complete the 180-degree flipping action. After flipping, the egg carton enters the labeling sorting section space. The labeling sorting section advances one unit per cycle and moves forward one station. When the labeling station 19 detects a product, the glue labeling component 5 and the label feeding component 6 complete the label taking, glue application, and labeling actions. After advancing one unit in the next cycle, the egg carton enters the stacking machine 7 to complete the product stacking.

[0024] Understandably, this utility model features a reasonable design and unique structure, integrating egg carton printing and labeling into a single machine, reducing the space occupied by the equipment. Egg carton printing and labeling can be completed in a single feeding and collecting (stacking) operation, thereby improving product qualification rate and production efficiency. It is compatible with printing and labeling various types of egg cartons, including 6+6, 10, 12, 15, and 18 cartons.
