[0017] In this embodiment, aluminum profiles are continuously input through the conveyor belt 2, with a high degree of automation, which improves the grinding efficiency and is suitable for large-scale production work; at the same time, the first pressing roller unit 41 and the second pressing roller unit 42 arranged in front and behind the pressing mechanism 4 are used to confirm that the upper end surface of the aluminum profile is consistent with the grinding surface of the grinding mechanism 3. Furthermore, the profile first passes through the scraper 5 on the first pressing roller unit 41 of the pressing mechanism 4 to clean the particle protrusions on the upper end surface of the aluminum profile, thereby extending the service life of the grinding mechanism 3.

[0018] In this embodiment, specifically, the first pressing roller unit 41 includes a first lifting module 411 arranged on the frame 1, a first fixed plate 412 arranged on the movable end of the first lifting module 411, a first pressing plate 413 elastically connected to the first fixed plate 412 by a spring, and a first pressing roller 414 arranged on the first pressing plate 413; the scraper 5 is arranged on the first pressing plate 413 and the cutting surface of the scraper 5 is arranged obliquely to the upper end surface of the aluminum profile.

[0019] Preferably, the vertical distance between the blade tip of the scraper 5 and the upper end surface of the aluminum profile is 0 to 3 mm. In this embodiment, it is further preferred that the vertical distance between the blade tip of the scraper 5 and the upper end surface of the aluminum profile is 1 mm. The above design can avoid the scraper 5 from damaging the aluminum profile secondary while removing the particle protrusions on the upper end surface of the aluminum profile. When the blade tip of the scraper 5 is in full contact with the upper end surface of the aluminum profile, the aluminum profile will not be easily damaged due to the action of the spring. Of course, the spring should have a large yield strength and the number is not limited, so as to prevent it from deviating with the conveying direction of the aluminum profile.

[0026] Under the above-mentioned preferred embodiment, the metal scraps generated by the grinding mechanism 3 in the closed shell 11 will be directly sucked out by the cleaning mechanism 6 to avoid the metal scraps from contaminating the working environment.

[0027] As a further preference of this embodiment, a grinding platform 12 is provided on the frame 1; the grinding platform 12 is located directly below the grinding mechanism 3 and is used to support the aluminum profile.

[0028] In this embodiment, it should be noted that the conveyor belt 2 used in this embodiment is a Teflon conveyor belt. In actual application, the polishing platform 12 is located inside the conveyor belt and close to its upper surface. Therefore, the polishing platform 12 can play a certain supporting role during polishing, avoiding the aluminum profile from jumping up and down during the polishing process and affecting the polishing quality.

[0029] In this embodiment, a guide mechanism 7 is preferably further included. It should be noted that the grinding mechanism 3 includes two grinding rollers 31 arranged side by side, and the guide mechanism 7 includes five limiting units 71; two limiting units 71 are provided on one side of the grinding roller 31, and one limiting unit 71 is provided between the two grinding rollers 31; the limiting unit 71 is composed of an adjustment frame 711 and a pair of guide rollers 712; the adjustment frame 711 is provided with a longitudinal groove and a transverse groove; the adjustment frame 711 is connected to the frame 1 via external fasteners; the guide rollers 712 are connected to the transverse groove via external fasteners, and the pair of guide rollers 712 are used to limit the left and right deviation of the aluminum profile. The above design can prevent the aluminum profile from deviating left and right, specifically by a pair of guide rollers 712 contacting the two side surfaces of the aluminum profile respectively. Multiple limiting units 71 can ensure that the aluminum profile maintains a straight conveying direction. Of course, the number and arrangement of the limiting units 71 in this embodiment are determined for the two grinding rollers 31, and can also be selected in other embodiments. In addition, under the action of the adjustment frame 711, the position and distance of the pair of guide rollers 712 can be adjusted according to the size of the aluminum profile.
