Description

Technical Field

[0001] This utility model relates to the field of cantilever rollers, and more specifically, to a cantilever roller with a buffer and shock absorption structure. Background Technology

[0002] Cantilever rollers, as common mechanical components, are widely used in many industrial fields, such as printing, packaging, and papermaking, for conveying, guiding, and processing materials. However, in actual operation, cantilever rollers are often subjected to various external forces, such as material impact and equipment vibration, which cause them to vibrate and sway. Traditional cantilever rollers have a relatively simple structure and lack effective cushioning and shock absorption measures. When subjected to external forces, vibration and sway are directly transmitted to various components of the cantilever roller, which not only affects the normal operating accuracy of the cantilever roller and reduces its material processing quality, but also accelerates the wear of its own parts and shortens its service life. Furthermore, the inability to flexibly adjust the height of the cantilever roller according to actual working needs results in poor adaptability to different working conditions. Therefore, developing a cantilever roller with cushioning and shock absorption functions and adjustable height is of significant practical importance. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The traditional cantilever roller structure in existing technologies is relatively simple and lacks effective buffering and shock absorption measures. When subjected to external forces, vibration and sway are directly transmitted to various components of the cantilever roller, which not only affects the normal working accuracy of the cantilever roller and reduces its material processing quality, but also accelerates the wear of the cantilever roller's own components and shortens its service life. The purpose of this utility model is to provide a cantilever roller with a buffering and shock absorption structure. It can realize the installation of a damping shock absorber on the top of the fixed plate. When the cantilever roller is subjected to external impact or vibration, the damping shock absorber can effectively absorb and buffer these energies, reduce the transmission of vibration and sway to other components of the cantilever roller, thereby improving the working stability of the cantilever roller and ensuring its material processing accuracy and quality. The setting of the lifting device allows the height of the cantilever roller to be flexibly adjusted according to actual working needs. By rotating the first rotating disk and the second rotating disk, the height of the mounting frame can be adjusted. Since the two threaded rods have opposite screw directions, the fixing stability of the mounting frame is improved, enhancing the adaptability of the cantilever roller to different working conditions.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] By installing a damping shock absorber on the top of the fixed plate, when the cantilever roller is subjected to external impact or vibration, the damping shock absorber can effectively absorb and buffer this energy, reduce the transmission of vibration and sway to other parts of the cantilever roller, thereby improving the working stability of the cantilever roller and ensuring its processing accuracy and quality of materials.

[0016] The lifting device allows the height of the cantilever roller to be flexibly adjusted according to actual working needs. By rotating the first and second rotating discs, the height of the mounting frame can be adjusted. Since the two threaded rods have opposite screw directions, the stability of the mounting frame is improved, enhancing the adaptability of the cantilever roller to different working conditions.

[0017] The wear-resistant bushing reduces direct friction between the rotating shaft and the limit frame, slows down the wear rate of components, and extends the service life of the cantilever roller. Attached Figure Description
