[0026] See also Figure 1-3 , a printing press cylinder mounting structure, comprising a supporting assembly and an adjusting assembly;

[0027] The support assembly includes a base 8, a printing table 9 is fixedly connected between the two bases 8, and a mounting table 2 is fixedly connected to the top of the base 8;

[0028] The adjustment component includes an adjustment slot 10, two adjustment slots 10 are fixedly opened on the mounting platform 2, one side of the mounting platform 2 is movably connected to a fixed platform 5, the middle of the fixed platform 5 is movably connected to a shaft sleeve 11, the middle of the shaft sleeve 11 is movably connected to a shaft 4, the bottom of the fixed platform 5 is fixedly connected to a spring shaft 6, the bottom of the spring shaft 6 is movably connected to a telescopic rod 7, one side of the two shafts 4 is fixedly connected to a roller 1, and the four corners of the fixed platform 5 are movably connected to screws 3.

[0029] In this embodiment, the adjustment groove 10 has an opening parallel to the surface of the mounting platform 2, and the inner wall of the adjustment groove 10 is provided with a guide structure for cooperating with the fixing platform 5, so as to fix or adjust the spatial position of the fixing platform 5 in the adjustment groove 10 by the screw 3.

[0030] Among them, the inner wall of the adjustment groove 10 is provided with a guide structure for cooperating with the fixed platform 5. These guide structures can be raised guide rails or grooves, which cooperate with the corresponding grooves or protrusions on the fixed platform 5 to ensure that the screw 3 can smoothly push the fixed platform 5 to move along the predetermined path of the adjustment groove 10 during the adjustment process, thereby achieving precise position adjustment.

[0031] In this embodiment, the shaft sleeve 11 is connected to the shaft 4 by a bearing, and the shaft 4 is allowed to rotate freely in the shaft sleeve 11 .

[0032] The shaft sleeve 11 and the shaft 4 are connected by a bearing, which not only reduces friction and wear, but also allows the shaft 4 to rotate freely in multiple directions in the shaft sleeve 11, which provides greater flexibility and stability for the drum 1 and also facilitates the rapid installation and replacement of the drum 1.

[0033] In this embodiment, an elastic connection is adopted between the spring shaft 6 and the telescopic rod 7, allowing the telescopic rod 7 to be telescoped within a certain range. A groove is provided at the top of the base 8, and the telescopic rod 7 can be clamped in the groove provided at the top of the base 8 to clamp the fixed platform 5 in the vertical direction.

[0034] Among them, the elastic connection design between the spring shaft 6 and the telescopic rod 7 allows the telescopic rod 7 to automatically adjust its length according to the pressure and load of the roller 1. This adaptive connection mechanism ensures a close fit between the roller 1 and the fixed platform 5, while absorbing the impact force and vibration that may be generated during the printing process.

[0035] In this embodiment, the base 8 and the printing table 9 are fixedly connected by welding or bolts, and the mounting platform 2 and the base 8 are connected by detachable bolts.

[0036] The welding or bolting connection between the base 8 and the printing table 9 provides a solid foundation to ensure the stability of the printing table 9 during high-speed operation.

[0037] In this embodiment, the shaft 4 is connected to the drum 1 via a flat key or a spline, and the shaft sleeve 11 is movably connected to the fixing platform 5 via a snap connection.

[0038] The flat key or spline connection between the shaft 4 and the drum 1 ensures effective transmission of torque while preventing the drum 1 from sliding or shifting on the shaft 4. This connection method is simple and reliable, and facilitates accurate positioning of the drum 1 and long-term stable operation.
