All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments of the present utility model fall within the scope of the present utility model. Embodiment

[0027] A preferred embodiment of a labeling device for cardboard box packaging provided by the present utility model is as follows Figures 1 to 4As shown in the figure: A marking device for carton packaging, including a base 1, a side plate 2 is fixedly connected to the top of the base 1, an electric rotating shaft 3 is rotatably connected inside the side plate 2, a conveyor belt 4 is closely attached to the surface of the electric rotating shaft 3, a label paper conveying mechanism 5 is fixedly connected to the top of the base 1 at one end of the conveyor belt 4, a connecting plate 6 is fixedly connected to the back of the label paper conveying mechanism 5, a first electric push rod 7 is fixedly connected to the surface of the connecting plate 6, an adsorption plate 8 is fixedly connected to the output end of the first electric push rod 7, and an auxiliary mechanism 9 is arranged above the base 1.

[0028] In this embodiment, the auxiliary mechanism 9 includes an adjustment component 91 and a dust removal component 92. By setting the auxiliary mechanism 9, the stability of the carton during marking can be improved, and at the same time, the dust on the surface of the carton can be removed.

[0029] In this embodiment, the adjustment component 91 includes a mounting plate 911, a handle 912, a positive and negative threaded rod 913, and a limiting rod 914. By setting the adjustment component 91, when the adjustment component 91 is in use, the positions of the two limiting rods 914 can be adjusted, so as to limit cartons of different models.

[0030] In this embodiment, the mounting plate 911 is fixedly connected to the side of the side plate 2, a handle 912 is rotatably connected to the side of the mounting plate 911, a positive and negative threaded rod 913 rotatably connected to the mounting plate 911 is fixedly connected to the tail of the handle 912, and two limiting rods 914 are threadedly connected to the surface of the positive and negative threaded rod 913.

[0031] In this embodiment, the two limiting rods 914 are designed to be parallel to each other. The two limiting rods 914 form a reverse movement structure through the positive and negative threaded rod 913. Rotate the handle 912 to control the rotation of the positive and negative threaded rod 913. At this time, the two limiting rods 914 will slide along the inside of the mounting plate 911, so as to adjust the positions of the two limiting rods 914, so as to limit cartons of different sizes with the two limiting rods 914.

[0032] In this embodiment, the dust removal component 92 includes a second electric push rod 921, a blower 922, and an air outlet 923. By setting the dust removal component 92, the operation of removing dust from the marking surface of the carton can be performed.

[0033] In this embodiment, the second electric push rod 921 is fixedly connected to the top of the base 1, a blower 922 is fixedly connected to the output end of the second electric push rod 921, and an air outlet 923 above the displacement conveyor belt 4 is fixedly connected to the bottom of the blower 922.

[0034] In this embodiment, the top of the conveyor belt 4 faces directly below the air outlet 923. The air outlet 923 forms a moving structure through the second electric push rod 921. The air outlet 923 blows out the air generated by the fan 922, blowing off the dust on the side of the cardboard box to be marked, preventing the dust from causing the label paper to adhere insecurely. When dust removal is performed at the air outlet 923, the position of the air outlet 923 can also be adjusted through the second electric push rod 921 so that it can blow off the dust on the label-attached side of cardboard boxes of different sizes. Embodiment

[0035] Based on Embodiment 1, a preferred embodiment of the labeling device for cardboard box packaging provided by the present utility model is as Figures 1 to 4 shown: A connecting rod 10 is fixedly connected to the top of the base 1. The top of the connecting rod 10 is fixedly connected to an assembly rod 11. The top of the assembly rod 11 is rotatably connected to an adapter plate 12. A torsion spring 13 fixedly connected to the assembly rod 11 and the adapter plate 12 is attached to the surface of the assembly rod 11. A scraper 14 is fixedly connected to one side of the adapter plate 12.

[0036] In this embodiment, the scraper 14 is made of rubber. The scraper 14 forms an automatic reset structure through the torsion spring 13. After the labeling is completed, the cardboard box continues to be conveyed forward and gradually contacts the scraper 14. The scraper 14 will rotate around the assembly rod 11 under the thrust of the cardboard box and will smooth the label paper just attached to the cardboard box, preventing the label paper from adhering insecurely. Then, it will return to the initial position under the action of the torsion spring 13 to perform the smoothing operation on the next group of cardboard boxes. Moreover, since the scraper 14 is made of rubber, the problem of scratching the label paper will not occur.

[0037] The working principle and usage process of the present utility model: First, when it is necessary to label a cardboard box, first adjust the positions of the two sets of limit rods 914 according to the size of the cardboard box. Rotate the handle 912 to control the rotation of the left-right threaded rod 913. At this time, the two sets of limit rods 914 will slide along the inside of the mounting plate 911, thereby adjusting the positions of the two sets of limit rods 914 to limit cardboard boxes of different sizes. The cardboard box can be placed on the conveyor belt 4. When the conveyor belt 4 is moving, it will convey the cardboard box to the left. When the cardboard box moves below the air outlet 923, the air outlet 923 will blow out the air generated by the fan 922, blowing off the dust on the side of the cardboard box to be marked, preventing the dust from causing the label paper to adhere insecurely. When dust removal is performed at the air outlet 923, the position of the air outlet 923 can also be adjusted through the second electric push rod 921 so that it can blow off the dust on the label-attached side of cardboard boxes of different sizes.

[0038] After dust removal is completed, the cardboard box continues to be conveyed forward under the action of the conveyor belt 4. Then, the label paper conveying mechanism 5 conveys the cardboard box to the adsorption plate 8. At this time, the adsorption plate 8 adsorbs the label paper. Next, the first electric push rod 7 is used to push the adsorption plate 8 to stick the label paper onto the cardboard box. After the labeling is completed, the cardboard box continues to be conveyed forward and gradually contacts the scraping plate 14. The scraping plate 14 will rotate around the assembly rod 11 under the thrust of the cardboard box and will smooth the label paper just pasted on the cardboard box to prevent the label paper from not adhering firmly. Then, it returns to the initial position under the action of the torsion spring 13 to perform the smoothing operation on the next group of cardboard boxes. Moreover, since the scraping plate 14 is made of rubber, the problem of scratching the label paper will not occur.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
