[0015] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0016] An assembled high-speed paper reel cylinder according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0017] Example

[0018] For easier understanding, see Figure 1 to Figure 2 The utility model provides an embodiment of an assembled high-speed paper reel cylinder, comprising: a transmission side shaft 11; an end cover 12; a housing 13, wherein the housing 13 is composed of a cylinder 131 and a flange 132, wherein one end of the cylinder 131 is fixedly connected to the flange 132 to ensure the overall stability under high-speed rotation and the coaxiality of the flange 132; an operating side shaft 14; a screw 15; and a bolt 16, which are used to assemble and connect the housing 13 and the end cover 12. The cylinder 131 and the flange 132 are fixed by interference fit and welding.

[0019] Furthermore, the flange 132 on the housing 13 is provided with a connection structure for receiving bolts 16, which is used for quick assembly and fixation of the housing 13 and the end cover 12. The transmission side shaft 11 is installed in the middle of one end of the end cover 12 by screws 15.

[0020] It should be noted that first, according to the needs, materials suitable for high-speed operation and with sufficient strength and rigidity, such as high-strength alloy steel, are selected, and the cylinder 131 and the flange 132 are precisely processed to ensure dimensional accuracy and surface finish, so as to prepare for subsequent interference fit and welding.

[0021] After precise measurement, one end of the cylinder 131 and the flange 132 are interference-fitted to ensure that the two are tightly fitted without gaps to improve overall rigidity and coaxiality. Subsequently, advanced welding techniques such as argon arc welding or laser welding are used to weld and fix the joint of the cylinder 131 and the flange 132 on the basis of interference fit to ensure welding quality and prevent displacement or deformation during high-speed rotation.

[0022] The flange 132 is designed with multiple evenly distributed bolt holes, which are used to receive the bolts 16 to ensure the quick and stable assembly of the housing 13 and the end cover 12. The end cover 12 is also provided with bolt holes at corresponding positions, which are fastened by bolts 16 and matching washers and nuts to form a reliable connection structure.

[0023] The transmission side shaft 11 is fixed at a pre-set position at the middle of one end of the end cover 12 by a high-strength screw 15 to ensure stable support of the shaft and effective transmission of power.

[0024] First, the processed barrel-flange assembly, i.e., the housing 13, is assembled with the end covers 12 at both ends by bolts 16, ensuring that all connection parts are tightened without looseness. Subsequently, the operating side shaft 14 is installed to complete the assembly of the main structure.

[0025] After assembly, the coaxiality of flange 132 is checked using professional instruments to ensure accurate alignment with the drive shaft.

[0026] Working principle: The transmission side shaft 11 is installed on the end cover 12 through a precise bearing system. When the power system of the paper machine is started, the transmission side shaft 11 receives the torque from the drive system and transmits the rotational power to the entire paper winding cylinder efficiently and losslessly through the solid connection of the screw 15. The continuity and reliability of power transmission are ensured, and it can remain stable even under long-term high-load operation. The cylinder 131 and the flange 132 are tightly combined through precise interference fit, and then welded to form a highly integrated shell structure. This design not only strengthens the overall strength of the shell, but also ensures that the flange 132 maintains strict coaxiality with the transmission side shaft 11 and the operating side shaft 14 under high-speed rotation, reduces vibration, improves running stability, thereby extending the service life of the equipment and improving the quality of paper winding. The preset bolt holes on the flange 132 allow the shell 13 to be quickly and accurately connected to the end covers 12 at both ends through bolts 16, simplifying the on-site assembly process and reducing assembly time and cost. At the same time, this design facilitates daily maintenance inspections and necessary component replacements, improving the flexibility and efficiency of the paper production line.

[0027] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
