Description

Technical Field

[0001] The utility model relates to the technical field of sanding devices, and particularly relates to a surface sanding device for aluminum profile production and processing. Background Art

[0002] With the wide application of aluminum profiles in fields such as construction and industry, the requirements for the surface quality of aluminum profiles are getting higher and higher; in the production and processing of aluminum profiles, surface sanding treatment is an important link, and its purpose is to remove defects such as burrs and oxide layers on the surface of aluminum profiles, improve surface smoothness and flatness, thereby enhancing the appearance quality and service performance of aluminum profiles.

[0003] Referring to the Chinese utility model patent "A surface sanding device for aluminum profile production and processing", the patent publication number is: "CN213289763U", which includes: a mounting base, a guiding mechanism and a sanding mechanism. The mounting base includes an operating table and supporting legs. The supporting legs are evenly arranged at the four corners of the lower end surface of the operating table, and the supporting legs are vertically and fixedly connected to the operating table. The guiding mechanism is installed on the upper end surface of the operating table, and the guiding mechanism is horizontally slidably connected to the operating table, which is convenient for users to stably place the aluminum profile on the upper end surface of the operating table when needed. Then, the user can stably adjust the position of the guiding plate on the operating table according to the size of the aluminum profile. When adjustment is needed, the user can hold the operation disk to stably rotate the threaded rod synchronously, and then through the cooperation between the threaded rod and the threaded sleeve, the position of the threaded sleeve on the threaded rod can be changed, so as to drive the guiding plate to move synchronously.

[0004] In the above use, the device can only sand one side of the aluminum profile and cannot process multiple surfaces of the aluminum profile at the same time. This leads to the need for multiple operations to complete the overall sanding of the aluminum profile in the actual production and processing process, which is not only inefficient, but also difficult to ensure the consistency of the sanding effect of each surface, affecting the overall quality of the aluminum profile.
