[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-4 As shown, the egg packaging box labeling device includes a vertical plate 1. The vertical plate 1 is sequentially provided with a winding wheel 2, a guide wheel 3, an upper and lower limit assembly, a labeling assembly, a reversing wheel 4, a pre-pressing assembly, and a rotatable winding wheel 5. The labeling assembly includes a top seat 6 and a label-tearing plate 7 mounted vertically on the vertical plate 1. The top seat 6 is provided with a moving cylinder 8. The drive shaft of the moving cylinder 8 is provided with a moving plate 9. The moving plate 9 is vertically provided with a labeling cylinder 10. The labeling cylinder 10 is slidably provided with a lifting seat 11, and the drive shaft of the labeling cylinder 10 is connected to the bottom of the lifting seat 11. The lifting seat 11 is rotatably provided with an adjusting seat 12. The adjusting seat 12 is provided with a bottom plate 13 facing downward. The bottom plate 13 is provided with a leveling wheel 14 and a label suction seat 15 at the front and rear, respectively. The lifting seat 11 is rotatably provided with an adjusting cylinder 16. The drive shaft of the adjusting cylinder 16 is rotatably connected to the adjusting seat 12.

[0022] In this embodiment, the front end of the device is equipped with a conveyor platform for conveying egg packaging boxes. After the egg packaging boxes are conveyed to the labeling position, the device performs the labeling operation on the egg packaging boxes.

[0023] Before using this device, install the roll of label base tape on the unwinding reel, and then pass the front end of the label base tape around the guide wheel, upper and lower limit components, labeling components, and reversing wheel in sequence, and finally pass it through the pre-compression component and fix it on the take-up reel.

[0024] In addition, the pre-compression assembly includes a fixed base 17, in which a fixed wheel 18 and an adjusting frame 19 are respectively rotatably arranged in the front and rear. A pre-compression wheel 20 is arranged below the adjusting frame 19 and rotatably facing the fixed wheel 18. A fixed plate 21 is provided on the back of the fixed base 17 on the upright plate 1. An adjusting screw 22 is screwed into the fixed plate 21, and the end of the adjusting screw 22 abuts against the adjusting frame 19.

[0025] When the label baseband needs to pass through the preload assembly, first loosen the adjusting screw, leaving a gap between the end of the adjusting screw and the adjusting frame. Then, move the adjusting frame backward, moving the preload roller on the adjusting frame a short distance away from the fixed roller. Pass the label baseband through this gap and secure it to the take-up roller. Next, rotate the adjusting frame forward, allowing the preload roller and fixed roller to press the label baseband tightly. Finally, tighten the adjusting screw until its front end contacts the adjusting frame. This allows the take-up roller to more stably wind up the label baseband.

[0026] In the diagram, the shafts of the fixed wheel 18 and the take-up wheel 5 both extend through the upright plate and are equipped with pulleys 23. A motor 24 is also mounted on the upright plate, and the drive shaft of the motor has a rotating wheel 25. A belt (not shown in the diagram) is fitted between the two pulleys and the rotating wheel. During the labeling process, the motor drives the rotating wheel, and under the action of the belt, the take-up wheel rotates to complete the take-up action.

[0027] When using this device to label the egg packaging box, first activate the external negative pressure equipment to generate negative pressure on the label suction seat. At the same time, the take-up roller starts to rotate, driving the label base tape to be released from the unwind roller. After being guided by the guide roller and limited by the upper and lower limit components, it is conveyed to the label tearing plate. Under the action of the label tearing plate, the label is peeled off from the label base tape, and the peeled label is attracted by the label suction seat.

[0028] When the egg carton is conveyed to the labeling position, the moving cylinder is activated, driving the moving plate forward so that the label held by the label suction holder is directly above the labeling position on the egg carton. Then, the labeling cylinder drives the lifting seat downwards, lowering the base plate so that the label on the label suction holder contacts the surface of the egg carton. At this point, the label suction holder stops adsorbing the label and releases it, thus initially attaching the label to the egg carton.

[0029] Then, the adjusting cylinder drives the adjusting seat to rotate downwards, allowing the leveling wheel to contact the label on the surface of the egg packaging carton. As the moving cylinder drives the moving plate to move back and forth, the leveling wheel rolls back and forth on the label surface, performing multiple leveling processes to ensure that the label adheres tightly to the surface of the egg packaging carton without wrinkles or bubbles. After leveling is completed, the adjusting cylinder drives the adjusting seat to reset, the labeling cylinder drives the lifting seat to move upwards to reset, and the moving cylinder drives the moving plate to move backwards to reset, preparing for the next labeling operation.

[0030] In the above process, the top seat 6 is provided with a guide post 26 facing forward, and the movable plate has a guide groove, with the guide post 26 located within the guide groove. When the movable cylinder drives the movable plate to move back and forth, the guide post slides within the guide groove, guiding and supporting the movement of the movable plate, ensuring the stability and accuracy of the movement of the movable plate.

[0031] As a specific structure, the upper and lower limiting assembly includes upper and lower cylinders 27 and a carrier plate 28 mounted on the vertical plate 1. The drive shaft of the upper and lower cylinders 27 is provided with a connecting seat 29. The connecting seat 29 has a groove 30. A pair of L-shaped limiting plates 31 are embedded in the groove 30. A locking screw (not shown in the figure) is screwed into the back of the limiting plate 31. The end of the locking screw abuts against the connecting seat 29.

[0032] Throughout the labeling process, the upper and lower surfaces of the label baseband are vertically limited by the upper and lower limit components. In practice, the locking screws can be loosened to move the limit plates left and right, adjusting the distance between the two limit plates to accommodate label basebands of different widths. Once the position of the limit plates is determined, the locking screws are tightened to fix the limit plates in place. After the label baseband passes through the upper and lower limit plates and the carrier plate, the upper and lower cylinders drive the connecting seat to move downwards, thereby causing the limit plates to move up and down. This allows the label baseband to contact the limit plates and the carrier plate respectively, achieving vertical positioning.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
