Description
Technical Field
[0001] The utility model relates to the technical field of egg box labeling, in particular to a rotary drum egg box labeling machine with inner side printing. Background Art
[0002] The rotary drum egg carton labeling machine is an automated equipment, an important equipment in the packaging industry. It is mainly used to automatically label egg cartons and other packaging boxes. Its working principle is to accurately stick the label on the egg box through the rotation of the drum.
[0003] The existing technology adopts a connecting rod structure to take materials, and places the egg box on the conveyor chain through a vacuum suction cup. After the chain is driven, it passes through a rotating drum that absorbs the label. The rotation direction of the drum is provided with a glue brushing mechanism and a connecting rod type label taking mechanism. The label taking and placing mechanism completes the placement of the label on the conveyor chain, and the chain is transported to the rotating drum to complete the label transportation. After the glue brushing mechanism makes the glue adhere to the label, the label is transferred to the egg box and attached under the rotation of the rotating drum. After completion, it is transported to the label pressing mechanism along the chain. The label pressing mechanism sets the trajectory for the cam, completes the rotation and compacts the label, and then is transported to the front of the stacking machine along the chain. A mechanism with a cam track is provided inside the stacking machine to complete the stacking output and stacking.
[0004] The disadvantages of the existing technology are that the label separation of the connecting rod type label removal mechanism is unstable during operation, and overlapping labels are conveyed to the drum mechanism. When the egg carton conveying chain lacks egg cartons, labels continue to be issued, which easily causes waste of labels and label accumulation, affecting the normal operation of the equipment. The mechanism does not have the function of printing on the inside of the egg carton and cannot complete the printing on the inside of the egg carton lid. Therefore, a rotary drum egg carton labeling machine with inner printing is needed to solve the above problems. Utility Model Content

The rotary drum egg carton labeling machine with inside printing is intended to solve the technical problems in the existing technology, such as unstable label separation, overlapping labels being conveyed to the rotary drum mechanism, and labels continuing to be issued when there is a lack of egg cartons on the conveying egg carton chain, which easily leads to waste of labels and label accumulation and affects the normal operation of the equipment. The mechanism does not have the function of printing on the inside of the egg carton and cannot complete the printing on the inside of the egg carton lid.

[0013] Beneficial effects of the utility model:
[0014] Compared with the traditional egg carton labeling machine with inner printing, the label separation is unstable and overlapping labels are conveyed to the drum mechanism. When the egg carton conveying chain lacks egg cartons, labels continue to be issued, which easily causes waste of labels and label accumulation and affects the normal operation of the equipment. This mechanism does not have the egg carton inner printing function and cannot complete the printing on the inside of the egg carton lid. The device can improve the operating stability of the egg carton labeling machine, avoid the waste of empty labels or the phenomenon of the drum being brushed with glue due to retention in the label suction drum area. The servo paging mechanism is more stable in label separation than the suction cup label picking and placing mechanism. It is also relatively intelligent, easy to control, and the control logic is simplified, making it easier for equipment debugging personnel to debug the equipment. The inner printing function component is set under the drum, which can effectively utilize the internal space of the equipment. There is no need to set the inner printing function on the egg carton, which causes the equipment to need to expand the space to meet the inner printing function, and the structure is simplified.

A universally adjustable optical fiber detection device is provided on one side of the mounting frame 616, and the inner printing drum 6 15 is provided with a lifting cylinder at the bottom, and a fiber optic detection device with universal adjustment is provided to detect whether there is a label on the label-absorbing mold 619 to prevent glue from being applied to the label-absorbing mold 619. By providing a set of lifting cylinders, it is possible to decide whether to enable the inner printing function according to need. Through holes are provided at the corresponding positions of the fixed plate 607 and the first rotating shaft 606. The first rotating shaft 606 is rotatably connected to the inside of the through hole of the fixed plate 607. The egg box detection photoelectric detection is used to detect whether an egg box passes through. When an egg box is detected to pass through, a high-level signal is output to the PLC, and the PLC then outputs a path signal to the intermediate relay. The corresponding friction paging device 617 can receive the signal from the slot-type photoelectric switch 621 to trigger the label issuance.If the egg box detection photoelectric switch does not detect the egg box, it outputs a low-level signal to the PLC, and the PLC outputs a circuit-breaking signal to the intermediate relay. The friction-type paging device 617 cannot receive the trigger signal of the slot-type photoelectric switch 621 and does not distribute the label. Therefore, the label distribution mechanism can decide whether to distribute the label according to the presence or absence of the egg box, thereby avoiding the waste of empty labels. The universally adjustable optical fiber detection device detects whether there is a label on the mold. When there is a label on the label-absorbing mold 619, a high-level signal is output to the PLC, and the PLC outputs a signal to trigger the solenoid valve of the brush glue roller drive cylinder. After the cylinder is driven, the brush glue roller is close to the label to complete the label brushing. When there is no label on the label-absorbing mold 619, a low-level signal is output to the PLC, which in turn outputs a signal to the solenoid valve driving the glue roller. After pneumatic actuation, the glue roller and the label are aligned to prevent glue from being applied to the label-absorbing mold 619. The first motor 602 is started, which drives the active synchronous wheel 603 to rotate. The active synchronous wheel 603 drives the driven synchronous wheel 605 via the first chain 604. The driven synchronous wheel 605 drives the first rotating shaft 606 to rotate. The first rotating shaft 606 drives the label-absorbing drum 612 to rotate. The label-absorbing drum 612 drives the label-absorbing mold 619 to rotate, attaching the label to the egg carton. The first rotating shaft 606 drives the first gear 613 to rotate. The first gear 613 drives the second gear 614 to rotate. The second gear 614 drives the inner printing drum 615 to rotate, printing the inner side of the egg carton.

[0025] When using the device, the egg box is placed on the egg box conveyor chain 8 through the automatic feeding mechanism 2, and is conveyed through the egg box conveyor chain 8. The egg box detection photoelectric sensor detects whether there is an egg box passing through. When it detects that an egg box has passed through, a high-level signal is output to the PLC, and then the PLC outputs a path signal to the intermediate relay. The corresponding friction paging device 617 can receive the signal from the slot-type photoelectric switch 621 and trigger the label issuance. If the egg box detection photoelectric switch does not detect the egg box, a low-level signal is output to the PLC, and the PLC outputs a path signal to the intermediate relay. Output circuit break signal, the friction paging device 617 cannot receive the trigger signal of the slot-type photoelectric switch 621, and no label is distributed. Therefore, the label distribution mechanism can decide whether to distribute labels according to the presence or absence of egg boxes, avoiding the waste of empty labels. The universally adjustable optical fiber detection device detects whether there is a label on the detection mold. When there is a label on the label-absorbing mold 619, a high-level signal is output to the PLC, and the PLC outputs a signal to trigger the solenoid valve of the brush glue roller to drive the cylinder. After the cylinder is driven, the brush glue roller is close to the label to complete the brushing of the label. When there is no label on the label-absorbing mold 619, a low-level signal is output to the PLC, which then outputs a signal to the solenoid valve of the adhesive roller drive cylinder.

The first motor 602 is started, and the first motor 602 drives the active synchronous wheel 603 to rotate. The active synchronous wheel 603 drives the driven synchronous wheel 605 to rotate through the first chain 604. The driven synchronous wheel 605 drives the first rotating shaft 606 to rotate. The first rotating shaft 606 drives the label-absorbing drum 612 to rotate. The label-absorbing drum 612 drives the label-absorbing mold 619 to rotate, and the label is attached to the egg box. The first rotating shaft 606 drives the first gear 613 to rotate, and the first gear 613 drives the second gear 614 to rotate. The second gear 614 drives the inner printing drum 615 to rotate to print the inside of the egg box; after completion, the egg box is transported to the label pressing component along the egg box conveying chain 8, and the second motor 702 is started. The second motor 702 drives the first sprocket 703, and the first sprocket 703 drives the second sprocket 705 to rotate through the second chain 704. The second sprocket 705 drives the second rotating shaft 706, and the second rotating shaft 706 drives the label pressing wheel 708. The label pressing wheel 708 drives the limit block 709, and the limit block 709 drives the limit rod 710 to slide inside the cam groove of the limit plate 707. The limit block 709 drives the label pressing plate 711 to rotate and compact the label, and then the egg box is transported to the automatic collection and stacking device 5 along the egg box conveying chain 8, and the automatic collection and stacking device 5 collects and stacks the egg boxes.
