Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0023] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] like Figure 1 、 Figure 6 As shown, an online grinding device for aluminum profiles is installed on the aluminum profile conveyor roller at the rear of the aluminum profile extruder to achieve online grinding. It includes a tray frame 2, a turning frame 3, a first rotating shaft 4, a second rotating shaft 5, a first pulley 6, a first bearing, a second bearing, a second pulley 7, a turning guide rail 8, a stud 9, a positioning nut, a first grinding wheel 10, and a second grinding wheel 11.

[0025] The turning frame 3 is arranged on the pallet frame 2 and one end of the turning frame 3 is hinged to the pallet frame 2 so that the turning frame 3 can be freely turned relative to the pallet frame 2 .

[0026] The first bearing is mounted on the tilting frame 3 via a bearing seat. The first rotating shaft 4 is connected to the first bearing, allowing the first rotating shaft 4 to rotate freely. A first pulley 6 is mounted on the first rotating shaft 4. A belt is connected between the motor 1 and the first pulley 6, allowing the motor 1 to drive the first rotating shaft 4 to rotate. The first grinding wheel 10 is mounted on the first rotating shaft.

[0027] The second bearing is mounted on the tray frame 2 via a bearing seat. The second shaft 5 is connected to the second bearing, allowing the second shaft 5 to rotate freely. A second pulley 7 is mounted on the second shaft 5. A belt is connected between the motor 1 and the second pulley 7, allowing the motor 1 to drive the second shaft 5 to rotate. The second grinding wheel 11 is mounted on the second shaft.

[0028] In the above technical solution, the method by which the motor 1 drives the first rotating shaft 4 and the second rotating shaft 5 to rotate is not limited to a belt or pulley structure. A gear chain structure can also be used to achieve the technical effect of driving the first rotating shaft 4 and the second rotating shaft 5 to rotate. The above technical solution can achieve the same speed of the first rotating shaft 4 and the second rotating shaft 5.

[0029] The lower end of the tilting guide rail 8 is connected to the pallet rack 2. The tilting guide rail 8 is provided with an arcuate slot. One end of the stud 9 is connected to the tilting rack 3. The stud 9 passes through the arcuate slot of the tilting guide rail 8. The other end of the stud 9 is connected to a positioning nut. The positioning nut rotates on the stud 9, so that the positioning nut cooperates with the tilting rack 3 to clamp the tilting guide rail 8 and position the tilting rack 3. The middle portion of the stud 9 is located in the arcuate slot of the tilting guide rail 8. As the tilting rack 3 rotates, the stud 9 can slide in the arcuate slot.

[0030] The turning angle of the turning frame 3 is adjusted by setting the stud 9 and the positioning nut. The specific steps are: first loosen the positioning nut, and when the turning frame 3 is turned to a suitable angle, tighten the positioning nut to fix the turning frame 3.

[0031] Through the above-mentioned setting, based on aluminum profiles of different thicknesses, the distance between the first grinding wheel 10 and the second grinding wheel 11 can be adjusted by adjusting the angle between the flip frame 3 and the tray frame 2 to achieve grinding of the upper and lower surfaces of the aluminum profile. At the same time, it can replace manual online grinding, ensure the consistency of the grinding effect, reduce grinding errors, and improve the grinding quality.

[0032] like Figure 2 As shown in the figure, as a preferred technical solution of the present invention, the first grinding wheel 10 includes a sleeve 12 and abrasive discs 13. The sleeve 12 is mounted on the first rotating shaft 4 and is connected to the first rotating shaft 4 via a key. Rotation of the first rotating shaft 4 drives the sleeve 12 to rotate. The abrasive discs 13 are provided in multiple groups, and the multiple groups of abrasive discs 13 are arranged circumferentially around the outer periphery of the sleeve 12. One end of the abrasive disc 13 is connected to the sleeve 12. With this arrangement, the other end of the abrasive disc 13 is free and used for grinding the profile.

[0033] The first grinding wheel 10 is mainly used to grind the upper surface of the profile. Depending on different application scenarios, the upper surface of the aluminum profile may be a non-flat surface. In order to achieve grinding of the upper surfaces of different aluminum profiles, the shape of the free end of the sanding sheet 13 can be designed and cut according to the shape of the upper surface of the aluminum profile, so that the free end of the sanding sheet 13 fits with the upper surface of the aluminum profile, so that the sanding sheet 13 can grind the upper surface of the aluminum profile in all directions.

[0034] In the above technical solution, since the sanding sheet 13 will be constantly worn during the grinding process, the cost of replacing the sanding sheet 13 is high. Figures 3 to 5 As shown, as a preferred technical solution of the present invention, the first grinding wheel 10 is a cylindrical structure with a through hole in its center for being mounted on the first rotating shaft 4 and connected to the first rotating shaft 4 via a key. The outer circumference of the grinding wheel is provided with grooves 14, which are arranged in multiple groups and arranged along the circumference of the grinding wheel. The ends of sandpaper 15 are fixed in the grooves 14. The length direction of the grooves 14 is the same as that of the first grinding wheel 10, and the grooves 14 and the first grinding wheel 10 are the same length.

[0035] As a supplement to the above technical solution, the sandpaper 15 and the first grinding wheel 10 may be fixedly connected by bonding.

[0036] As a supplement to the above technical solution, the sandpaper 15 can also be assembled with the first grinding wheel 10 in the following manner.

[0037] The opening of the groove 14 is continuously reduced from the bottom to the top. The bottom of the groove 14 is an end of the groove 14 close to the axis of the first grinding wheel 10, and the top of the groove 14 is located on the outer surface of the first grinding wheel 10.

[0038] A cylindrical fixed shaft 16 is disposed within the groove 14 and is inserted from one longitudinal end of the groove 14. The longitudinal end of the groove 14 corresponds to the longitudinal end of the first grinding wheel 10. The diameter of the fixed shaft 16 is smaller than the width of the upper opening of the groove 14, preventing the fixed shaft 16 from being removed from the upper end of the groove 14. The lower end of the sandpaper 15 is wrapped around the fixed shaft 16.

[0039] When the first grinding wheel 10 rotates, the fixed shaft 16 is driven by the centrifugal force. Since the opening of the fixed shaft 16 continues to shrink, the fixed shaft 16 is engaged in the groove 14, thereby fixing the fixed shaft 16. Since the sandpaper 15 is wrapped around the fixed shaft 16, the sandpaper 15 is clamped between the fixed shaft 16 and the side wall of the groove 14, and the end of the sandpaper 15 is fixed.

[0040] When assembling the sandpaper 15 and the fixed shaft 16 into the groove 14 of the first grinding wheel 10 , the sandpaper 15 can be wrapped around the fixed shaft 16 first, and then the sandpaper 15 and the fixed shaft 16 are inserted into the groove 14 from one end in the longitudinal direction of the groove 14 .

[0041] As a supplement to the above technical solution, a countersunk hole 17 is provided on the outer peripheral surface of the first grinding wheel 10, and the countersunk hole 17 is arranged crosswise with the groove 14. The bolt is screwed into the countersunk hole 17 so that the nut part of the bolt is located in the groove 14 where the fixed shaft 16 is located. The nut of the bolt abuts against the fixed shaft 16, and the nut of the bolt applies downward pressure to the fixed shaft 16, so that the bolt can further fix the fixed shaft 16.

[0042] The axial direction of countersunk hole 17 is different from that of groove 14. The countersunk hole 17 includes a head fixing hole and a screw hole. The fixing hole is located above the screw hole and has a larger diameter than the screw hole. The inner wall of the screw hole is provided with threads for bolt connection. The fixing hole can span the upper ends of several grooves 14. The specific groove 14 into which the fixed shaft 16 is inserted can be selected based on the specific location of the fixing hole.

[0043] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
