[0002] Cigarette seal printing is an important link in cigarette packaging production. Its printing quality directly affects the appearance and market competitiveness of the product. At present, micro-gravure printing technology using rollers, embossing strips and scrapers is widely used in cigarette seal printing due to its high precision and high efficiency.

This method is simple to operate, but the adjustment accuracy is low and it takes a long time; the second is to adjust the printing pressure through a hydraulic or pneumatic system. Although this method improves the adjustment efficiency, the system is complex and the cost is high; the third is to use a motor-driven method to adjust the position of the printing roller. This method can achieve a certain degree of automation, but it is difficult to respond to changes in the characteristics of the printing material in real time, and the printing pressure is difficult to adjust. The inability to adjust leads to large fluctuations in printing quality.

[0052] The implementation principle of a cigarette seal micro-gravure printing pressure adaptive mechanism in the embodiment of the present application is: When it is necessary to print the cigarette seal, the cigarette seal is placed between the stamping strip 3 and the roller 1, and the driving motor 2 drives the reciprocating screw rod 2 91 to rotate. Under the limiting action of the strip groove 831, the slider 92 slides along the strip groove 831, and the slider 92 drives the sliding ball 53 to drive the stamping strip 3 to approach the roller 1. The elastic rope 1 57 and the elastic rope 2 58 release or contract the elastic force according to the extension and retraction of the telescopic slide rod 52, so as to adjust the printing pressure of the stamping strip 3 on the roller 1 according to the position and extension length of the telescopic slide rod 52, so as to respond to the changes in the characteristics of the printing material in real time, adjust the printing pressure, and improve the quality of the printed product.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
