[0028] The color mark sensor adjustment assembly includes: a color mark sensor fixing frame 16, a color mark sensor adjustment block 17, a color mark sensor 15, and a labeling abutment plate 14.

The labeling abutment plate 14 is made of a stainless steel plate that is bent, welded and punched, and the labeling abutment plate 14 is connected and fixed to the overall frame 2 of the labeling mechanism by four hexagonal screws.

[0029] The packaging film guide transmission assembly includes: a packaging film guide rod 11 and guide rollers arranged around the overall frame 2 of the printing and labeling mechanism. The packaging film guide rod 11 is fixedly assembled by a clamping seat and a stainless steel guide rod. The packaging film guide rod 11 is located on the left side of the labeling abutment plate 14. The packaging film guide rod 11 is used for guiding and limiting the packaging film 3, and the setting height of the stainless steel guide rod is lower than the lower edge height of the front side adjustment movable block 9 and the rear side adjustment movable block 26 to prevent the packaging film 3 from being scratched and damaged by the front side adjustment movable block 9 and the rear side adjustment movable block 26.

[0030] The specific implementation process of the device of this embodiment in the production process is as follows: first adjust the position of the color mark sensor 15 according to the requirements to ensure accurate color mark sensing, then use the front side adjustment movable block 9 and the rear side adjustment movable block 26 to adjust the front and rear positions of the printing and labeling mechanism fixed frame 4 to determine the front and rear positions of the labels attached to the packaging film 3, and then set the delay parameters between the color mark sensing and the labeling action to control the left and right positions of the labels attached to the packaging film 3. Finally, adjust the angle and strength of the label elastic pressing plate 13, the labeling brush 18, and the guide limit pressing plate 20 to ensure the stability of the label paper 6 conveying and label pasting. Then start the device, the printer 5 starts to print the logistics barcode on the label paper and conveys the printed label paper 6 out, and is led out to the right under the limit conveying of the fixed conveying wheel 22 and the movable conveying wheel 21. The movable conveying wheel 21 drives the label paper 6 to move downward using the buffer slide rail 23 under the action of gravity. When the lower side buffer proximity switch 30 senses the movable conveying wheel 21, it means that enough label paper 6 has been buffered, and the printer 5 stops printing and outputting. The synchronous vertical packaging machine 1 starts packaging, pulling the packaging film 3 at the labeling position below to move rightward to form a packaging bag. During the process of the packaging film 3 moving rightward by the length of a packaging bag, the color mark sensor 15 senses the color mark on the packaging film 3 once, delays for a period of time, and the recycling servo motor 7 runs for a certain period of time to drive the bottom paper reel 8 and the lower recycling power rubber roller 28 to rotate counterclockwise to pull the label bottom paper 25 to the left, so that the label on the label paper 6 printed with the logistics barcode is separated by the label stripping head 12, and the label printed with the logistics barcode is driven by the moving packaging film 3 to adhere to the surface. After being pressed and brushed by the label elastic pressing plate 13 and the labeling brush 18, the label is finally firmly attached to the surface of the packaging film 3. In this reciprocating manner, the packaging film 3 at the labeling location continuously moves to the right, the color mark sensor 15 continuously senses the color mark, the recycling servo motor 7 continuously drives the bottom paper reel 8 and the lower recycling power rubber roller 28 to rotate counterclockwise, and the labels printed with the logistics barcode are continuously attached to the packaging film 3. As the labeling action continues, the buffered printed label paper 6 becomes less and less, and the active conveying wheel 21 is driven by the label paper 6 to move upward under the action of the buffer slide rail 23. When the upper side buffer proximity switch 24 senses the active conveying wheel 21, it means that there are not many cached printed label papers 6. At this time, the printer 5 works again to print and output the label paper until the lower side buffer proximity switch 30 senses the active conveying wheel 21 again. In this process, the packaging mechanism bag making and the labeling mechanism labeling actions are performed synchronously. The device is complete.

[0031] The utility model has a novel design and a reasonable concept. It mainly has the functions of printing the required content on the label paper, separating the label from the base paper and then attaching the label to the packaging film. At the same time, it has a simple structure, saves costs, has minimal dependence on the environment, and is easy to operate. It has the functions of pressing and brushing labels while ensuring that the label is firmly adhered and beautiful.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0033] The above is only a preferred implementation case of the utility model, and does not limit the utility model in any form. Although the implementation process of the utility model is described in detail above, for those familiar with the art, they can still modify the technical solutions recorded in the above examples, or replace some of the technical features therein with equivalents. All modifications and equivalent replacements made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
