Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machine devices, in particular to a rewinding machine bottom knife roller flat roller device used in a pulp cleaning production process. Background Art

[0002] Rewinding machines are generally used for rewinding and slitting mica tapes, paper, and films, and they play the role of cutting one piece in two. They are often used to slit wide rolls of materials, and they play an important role in the subsequent slitting. They are special equipment for paper, mica tapes, and films.

[0003] At present, the existing utility model fixes a bottom knife roller flat roller horizontal to the bottom knife roller at the lower end of the bottom knife roller. When the web paper is in the rewinding process, the paper passes through the bottom knife roller flat roller, and the bottom knife roller flat roller gives the paper a force pointing directly downward, thereby pressing the paper surface and preventing the bottom knife roller from directly pressing on the paper surface, thereby solving the problem of bottom knife marks caused by the grooves on the surface of the bottom knife roller of the rewinder.

[0004] For example, a bottom knife roller flat roller device of a rewinding machine disclosed in the authorization number CN206842668U includes a bottom knife roller, a fixed sleeve, a stud, a flat plate, a bearing sleeve and a bottom knife roller flat roller. The fixed sleeve is composed of an upper arch sleeve and a lower arch sleeve. The upper arch sleeve is provided with a through hole, and the lower arch sleeve is provided with a blind hole on the side close to the semi-cylinder, and the bolt passes through the through hole and the blind hole. The lower arch sleeve on the side opposite to the blind hole is provided with a stud hole, and a stud is provided in the stud hole. The stud is provided with an upper locking nut, a limit nut, a flat plate and a lower locking nut. A bearing sleeve is welded on the lower side of the flat plate, and a bearing is provided on one side of the bearing sleeve, and a bottom knife roller flat roller is provided between the bearings. A bottom knife roller is provided between the fixed sleeves. The upper arch sleeve and the lower arch sleeve cooperate to form a square structure, and the semi-cylindrical hole of the upper arch sleeve and the semi-cylindrical hole of the lower arch sleeve fit into a complete circular through hole. The blind hole is a threaded hole. The stud hole is a threaded hole. The stud is tightened through the thread in the stud hole. The stud passes through the flat plate, and a limit nut is provided on the upper side of the flat plate, and a lower locking nut is provided on the lower side. The limit nut adjusts the position of the flat plate. Ear frames are provided on one side of the bearing sleeve and the bearing, and the two ear frames are located on the same horizontal line, and bolts are provided between the two ear frames. The bottom knife roller and the fixed sleeve are connected in a rolling manner. However, such a bottom knife roller and flat roller device of the rewinding machine adopts a structural design of four bolts to install the fixed sleeve, which requires the use of tools for disassembly and assembly, and is not convenient for quick disassembly and assembly of the fixed sleeve to replace the bottom knife roller. At the same time, it is not convenient to automatically adjust the guide roller and flat roller buffer to tightly adhere to the paper roll.

[0005] It can be seen from the solution disclosed in the above-mentioned existing patent documents that the structural design of installing the fixing sleeve with four bolts requires the use of tools for disassembly and assembly, which is not convenient for quickly disassembling and assembling the fixing sleeve to replace the bottom knife roller. At the same time, it is not convenient to automatically adjust the guide roller and flat roller buffer to tightly adhere to the paper roll. Therefore, it is necessary to improve the existing technology. Utility Model Content
