[0027] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0028] Reference Figures 1 to 4 As shown, a printing structure for a medicine bag printing machine is provided, including an X-axis beam 1, a printhead support 2 movably mounted on the X-axis beam 1, a plurality of printheads 3 mounted on the printhead support 2, a micro-negative pressure adsorption platform for making the bag surface wrinkle-free is provided below the printheads 3, a curing device for rapid ink drying is provided below the printheads 3, and an internal circulation ink path structure is provided inside the printheads 3 to prevent the ink from drying out.

[0029] In this embodiment, the printhead 3 can move back and forth along the length of the X-axis beam 1 following the printhead stand 2. The medicine bag roll passes under the curing device. After the printhead 3 sprays ink onto the medicine bag, the ink is quickly dried by the curing device to prevent adhesion. At the same time, it passes through the micro-negative pressure adsorption platform, which makes the surface of the medicine bag stick tightly to avoid wrinkles, and the printed content is clearer. The printhead 3 is equipped with an internal circulation ink path structure. When the equipment is idle for more than a set time, the system automatically performs low-frequency pulse jet spraying from the nozzle of the printhead. Combined with the impurity removal and drainage pipe, the residual impurities in the printhead cavity are discharged, which effectively extends the life of the printhead and reduces the maintenance frequency.

[0030] In some embodiments of this utility model, a sliding block 11 is movably arranged on the X-axis beam 1. The sliding block 11 can move back and forth along the length direction of the X-axis beam 1. The nozzle support 2 is fixedly installed on the sliding block 11. Through the cooperation of a stepper motor and a synchronous belt, the nozzle 3 is accurately positioned with a control accuracy of ≤±0.2mm.

[0031] In some embodiments of this utility model, the curing device includes a UV curing lamp group 41 and a hot air drying component 42. The UV curing lamp group 41 is arranged on both sides below the printhead 3, and the hot air drying component 42 is arranged below the printhead 3. The UV curing lamp group 41 and / or the hot air drying component 42 are set and start synchronously after printing, with a control delay of less than 1 second to prevent ink smudging, adhesion and tailing, and to achieve rapid curing.

[0032] Furthermore, the UV curing lamp assembly 41 includes a partition 411, a UV curing lamp body 412, and a U-shaped auxiliary frame 413. The partition 411 is fixedly installed on both sides below the nozzle 3. The partition 411 and the U-shaped auxiliary frame 413 are fixedly connected to form an installation space 414. The UV curing lamp body 412 is movably disposed within the installation space 414. The width of the installation space 414 is greater than the width of the UV curing lamp body 412, so that the UV curing lamp body 412 can move back and forth within the installation space 414. The U-shaped auxiliary frame 413 has several heat dissipation holes. The UV curing lamp body 412 can be directly inserted into the installation space 414, and the position of the UV curing lamp body 412 in the installation space 414 can be adjusted according to the actual situation, thereby adjusting the distance between the UV curing lamp body 412 and the medicine bag roll. The two sides of the U-shaped auxiliary frame 413 are sufficient to hold the UV curing lamp body 412 in place so that it does not fall over and can operate normally.

[0033] Meanwhile, the hot air drying assembly 42 includes a hot air device 421 and a mounting plate 422. The mounting plate 422 has a mounting groove, and the hot air device 421 is fixedly installed on the mounting groove. An L-shaped guide rail 423 is fixedly installed at the bottom of the end of the partition plate 411 away from the UV curing lamp body 412. The mounting plate 422 is movably mounted on the L-shaped guide rail 423. The mounting groove is a hollow structure, and the hot air device 421 can blow hot air through the mounting groove to the medicine bag roll to achieve rapid curing. The mounting plate 422 can be adjusted along the length of the L-shaped guide rail 423 so that the ink sprayed from the nozzle 3 can be printed on the medicine bag.

[0034] In some embodiments of this utility model, the internal circulation ink path structure includes a positive pressure ink pipe, a return ink pipe, and an exhaust device. Both the positive pressure ink pipe and the return ink pipe are connected to the printhead 3 to form a printhead circulating ink supply channel. Both the positive pressure ink pipe and the return ink pipe are connected to the exhaust device to ensure no air bubbles remain inside the printhead 3. The internal circulation ink flow design prevents ink from drying out and ensures immediate printing upon startup. When the equipment is idle for more than a set time, the system automatically performs low-frequency pulse inkjet injection from the nozzle. Combined with the impurity removal and drainage pipe, residual impurities in the printhead cavity are discharged, effectively extending the printhead's lifespan and reducing maintenance frequency. Pulse injection maintenance procedure: The "low-frequency pulse inkjet" function is automatically activated when the equipment is idle for more than a set time (e.g., 30 minutes).

[0035] In some embodiments of this utility model, the number of nozzles 3 is five, and the five nozzles 3 are evenly distributed on the nozzle support 2.

[0036] Preferably, printhead 3 is a piezoelectric inkjet printhead, which is compatible with medical bags.

[0037] In some embodiments of this utility model, the micro-negative pressure adsorption platform is provided with multiple adsorption holes and connected to a vacuum pump. The negative pressure source is adjusted by the vacuum pump (-10~-30kPa) to ensure that the printed bag surface is adhered and to prevent wrinkles and pattern distortion.

[0038] In some embodiments of this utility model, the nozzle 3 is provided with a drain port, which is connected to a drain pump or a collection bottle.

[0039] In some embodiments of this utility model, a sensor is provided inside the nozzle 3 to detect parameters such as nozzle temperature, pressure, and flow rate of the nozzle 3.
