Description
Technical Field
[0001] The invention relates to the technical field related to profile processing, in particular to a sanding device for aluminum materials. Background Art
[0002] As the name suggests, sanded boards are calendered boards that are sanded with a sanding machine in order to make them easier to stick finishing materials on. Therefore, sanded boards are generally thinner than calendered boards.
[0003] Sanding makes the surface of the board smooth and increases the strength of the surface at the same time. The thickness is uniform and consistent. It is suitable for various veneer processes and various standard structural parts, and is convenient for decoration and furniture making.
[0004] Generally, for the sanding of profiles, such as aluminum profiles, the grinding wheel is often used to reciprocate the profile to sand the profile surface. However, such treatment cannot cope with profiles with various curved surface designs. At the same time, the reciprocating sanding treatment will not only cause a large amount of wear and tear on the profile, but also cannot handle the burrs on the profile surface well, resulting in defects in the surface treatment of the profile, which leads to a decrease in treatment efficiency and treatment pass rate. Summary of the invention
[0005] The present invention aims to overcome the above-mentioned deficiencies in the prior art and provides a sanding device for aluminum materials that can better process curved surfaces and burrs.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

If burrs are encountered, the sanding roller performs a primary sanding treatment on the burrs, and then the position where the burrs are located is subjected to a secondary sanding treatment by the cutter head. When encountering a curved surface position of the aluminum profile, the existing surface treatment is directly replaced by the point treatment of the cutter head, so that the sanding device can meet the curved surface sanding operation of the aluminum profile. In actual operation, the secondary sanding treatment can better handle the burrs on the surface of the aluminum profile than the existing single grinding wheel sanding treatment, and the processing efficiency is also greatly improved, and there is no need for reciprocating treatment.

Through the structural design of the second ventilation duct, the air volume of the air outlet can be increased, so that impurities or aluminum chips on the surface of the aluminum profile can be effectively blown away, preventing impurities from remaining on the surface of the aluminum profile and affecting the sanding effect.

[0013] Preferably, the side of the long slot away from the pressure sensor is in an arc shape, the rotating shaft of the sanding roller is installed in the long slot and is located near the arc side, a compression spring is provided in the long slot, one end of the compression spring is installed in the long slot, and the other end of the compression spring is installed on the rotating shaft. Through the structural design of the long slot and the design of the compression spring, the change of the sanding roller can be better detected, so that the sanding device can make corresponding responses in time.
[0014] Preferably, the surface of the sanding roller is provided with a plurality of cutting strips, which are distributed in a rhombus grid on the surface of the sanding roller, and the cross-section of the cutting strip is triangular.
