It is widely used in the product packaging process of industries such as food, pharmaceuticals, and daily chemicals. Its core function is to replace manual labor, improve packaging efficiency, and ensure that the applied material is flat and bubble-free, meeting the needs of product appearance consistency and standardized production.

[0003] However, existing devices can only position packaging boxes of specific sizes, making it difficult to flexibly adapt to more specifications. In actual production or packaging scenarios, the sizes of packaging boxes to be processed often exhibit diverse characteristics and are not fixed and uniform specifications. This makes it difficult for existing devices to meet the diverse needs in actual operation. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging box mapping device. By setting a positioning part, it solves the problem that the existing device can only position packaging boxes of a specific size and is difficult to flexibly adapt to more specifications. However, in actual production or packaging scenarios, the size of the packaging boxes to be processed often presents diverse characteristics and is not a fixed and uniform specification. This makes it difficult for the existing device to meet the diverse needs in actual operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a packaging box labeling device, comprising a conveyor table and a digital printing machine disposed on top of the conveyor table, and further comprising: a positioning part disposed on top of the conveyor table; a drying part disposed on top of the conveyor table; the positioning part comprising a positioning component disposed on top of the conveyor table; and a driving component disposed on the positioning component; the positioning component comprising two support plates fixedly connected to the top of the conveyor table, two sliding rods fixedly connected to one side of the two support plates close to each other, two sliders slidably connected to the outer walls of the two sliding rods, a positioning plate fixedly connected to the bottom of each slider, and a connecting member disposed on each slider, the two sliders being symmetrically distributed on both sides of the two sliding rods; the connecting member comprising a connecting rod hinged to the top of each slider, the two connecting rods being symmetrically distributed on both sides of a fixed block.

[0006] Furthermore, the drying section includes a drying assembly mounted on top of the conveyor table; and a lifting assembly mounted on the drying assembly.

[0007] Furthermore, the drive assembly includes a fixed block fixedly connected to the outer wall of the two slide rods. A motor is mounted on the fixed block, and the output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A transmission component is mounted on the rotating shaft. A motor slot is provided on the top of the fixed block, and the motor is located in the slot. The transmission component includes a connecting rod two fixedly connected to the outer wall of the rotating shaft. The ends of the two connecting rods away from the slide are hinged to the connecting rod two.

[0008] Furthermore, the drying assembly includes a slide plate disposed on top of the conveyor table, with a dryer fixedly connected to the top of the slide plate and the bottom of the dryer extending beyond the slide plate.

[0009] Furthermore, the lifting assembly includes several slide rods 2 fixedly connected to the top of the conveyor table. The top of each slide rod 2 is fixedly connected to two top plates. The top of each of the two top plates is fixedly connected to a hydraulic push rod. The output ends of the two hydraulic push rods are fixedly connected to the slide plate. The output ends of the two hydraulic push rods extend to the outside of the two top plates and are slidably connected to the two top plates.

[0010] This utility model has the following beneficial effects: 1. By setting up a positioning part, when printing on the packaging box, it is placed on the conveyor table, the motor is started, and the motor drives the connecting rod two to rotate through the rotating shaft. Since the connecting rod two is hinged to the two connecting rods one, and the other end of the connecting rod one is hinged to the slider on the sliding rod one, the two sliders will drive the positioning plates on them to move closer to each other through the transmission of the connecting rod one, and center the packaging box on the conveyor table. After the positioning is completed, the conveyor table is started to transport the packaging box to the digital printing machine to complete the printing. This positioning mechanism can ensure the stable position of packaging boxes of different specifications during printing and improve the printing accuracy. 2. By setting up a drying section, after the packaging box is printed, it is conveyed to the bottom of the dryer by the conveyor table. The dryer quickly dries the printed packaging box. If it is necessary to adjust the drying distance according to the packaging box of different thicknesses, two hydraulic push rods are activated. Under the guidance of multiple slide rods, the hydraulic push rods push the slide plate to move the dryer up and down until the appropriate distance is adjusted. This adjustment mechanism can flexibly adapt to the drying needs of packaging boxes of different specifications, ensuring the drying effect while avoiding overheating.

The dryer 312 can quickly air dry the printed packaging box. If it is necessary to adjust the drying distance to adapt to packaging boxes of different thicknesses, the two hydraulic push rods 323 can be activated. At this time, the hydraulic push rods 323 will be guided by multiple slide rods 321 to push the slide plate 311 to drive the dryer 312 to move up and down until the appropriate drying distance is adjusted. Through this adjustment mechanism, the drying needs of packaging boxes of different specifications can be flexibly adapted to, ensuring the drying effect while avoiding overheating.

[0019] DeepThink Paper Bag Digital Printing Machine 112: This is a high-efficiency and environmentally friendly printing device, mainly used for personalized and rapid printing of corrugated boxes, e-commerce gift boxes, paper bags, etc. It adopts a SinglePass mode with a fixed print head, eliminating the need for left and right scanning. Printing speeds can reach 30 meters per minute, and it can print from a single sheet, effectively solving the problems of rush orders, small-batch printing, and scattered orders. This printing machine requires no plate making and can quickly change plates online, saving significant plate-making and labor costs. It is also simple to operate, allowing even ordinary people to learn how to use it. It uses water-based environmentally friendly ink, which is healthy and odorless. It is equipped with high-precision printheads, such as the H452 printhead, which are highly accurate and have low maintenance costs. The working principle of the DeepThink paper bag digital printing machine is mainly based on digital image processing and inkjet technology. First, the user edits and adjusts the color and resolution of the image to be printed through computer software, and the processed image is transmitted to the printing machine in the form of digital signals. Then, the printhead of the printing machine sprays water-based ink onto the surface of the paper bag material at extremely high speed and precision through tiny nozzles. Depending on the printhead driving method, thermal inkjet or micro piezoelectric inkjet technology may be used.

[0020] Dryer 312: This is a specialized piece of equipment designed for the post-printing process of paper bags. Its core function is to quickly remove moisture from water-based inks used in printing, achieving ink curing and setting, preventing pattern smudging and sticking, and preventing paper bags from deforming and becoming brittle due to moisture, thus ensuring printing quality and finished product stability. These machines often employ a design that combines conveyor belt transport with precise temperature control. Common heating methods include infrared radiation heating and hot air circulation heating. The speed and temperature of the conveyor belt can be adjusted to suit different thicknesses of paper bags and ink types. It also features non-contact heating, which avoids damage to the printed pattern and the paper bag substrate. A mainstream model on the market, such as the VastexLO-E2D, is suitable for small to medium batch production. It is equipped with a 76cm wide conveyor belt and an 89cm long heating chamber, achieving curing of 88 water-based ink prints per hour with a power of 4.6kW. It supports adjustable drying time from 1 to 5 minutes, and production capacity can be expanded by adding more heating chambers.

[0021] It should be noted that the control of the conveyor 111, digital printing machine 112, motor 222, dryer 312 and hydraulic push rod 323 in this application can all be achieved by using the program set in the control panel and inputting relevant parameters as needed for automated control. The setting of this control method can be realized by existing technology, such as PLC.

[0022] A specific application of this embodiment is as follows: When printing on a packaging box, it can be placed on the conveyor table 111. After placement, the motor 222 is started. The motor 222 will drive the connecting rod 224 to rotate via the rotating shaft 223. Since two connecting rods 215 are hinged to the connecting rod 224, and the other ends of the two connecting rods 215 are respectively hinged to the sliders 213 sliding on the two sliding rods 212, when the motor 222 drives the connecting rod 224 to rotate via the rotating shaft 223, the two connecting rods 215 can drive the two sliders 213 hinged to them to move closer together to center the packaging box on the top of the conveyor table 111. After positioning is completed, the conveyor can be started. The conveyor 111 transports the packaging boxes to the digital printing machine 112 for printing. This positioning mechanism ensures that packaging boxes of different sizes remain stable during the printing process, improving printing accuracy. After printing, the packaging boxes are transported by the conveyor 111 to the bottom of the dryer 312. The dryer 312 can quickly air dry the printed packaging boxes. If the drying distance needs to be adjusted to accommodate packaging boxes of different thicknesses, two hydraulic push rods 323 can be activated. Under the guidance of multiple slide rods 321, the hydraulic push rods 323 will push the slide plate 311 to move the dryer 312 up and down until the appropriate drying distance is reached. This adjustment mechanism can flexibly adapt to the drying needs of packaging boxes of different sizes, ensuring the drying effect while avoiding overheating.
