[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 This utility model provides a technical solution: a grinding device for the outer surface of an aluminum plate, comprising a base 1, two conveyors 2 mounted on the base 1, with a spacer plane 3 between the two conveyors 2, a lower grinding roller 4 rotatably connected to the base 1 at the spacer plane 3, a motor 5 mounted on the side of the base 1, the output end of the motor 5 penetrating through the spacer plane 3 and fixedly connected to one end of the lower grinding roller 4, a bracket 6 fixedly connected to the base 1, and sliding grooves 7 on both sides of the bracket 6, with concave frames 8 slidably connected to the sliding grooves 7, and a first movable rod 9 rotatably connected within the concave frames 8. An upper grinding roller 10 is sleeved and connected to the first movable rod 9. A placement plate 11 is fixedly connected to the concave frame 8 outside the sliding groove 7. A second motor 12 is installed on the placement plate 11, and the output end of the second motor 12 is connected to the end of the upper grinding roller 10. A lifting assembly is installed between the bracket 6 and the concave frame 8. Two side plates 13 are fixedly connected to the left side of the bracket 6. A moving assembly is installed between the two side plates 13, and a side grinding roller 14 is connected to the moving assembly. The aluminum plate is placed on the conveyor 2 on the left side of the base 1, and the aluminum plate is conveyed by the conveyors 2 on the left and right sides of the base 1. The motor is started. Machine 5 and motor 12 drive the lower grinding roller 4 and upper grinding roller 10 to rotate simultaneously. The rotation direction of the lower grinding roller 4 and upper grinding roller 10 is opposite to the movement direction of the aluminum plate, enabling simultaneous grinding of both sides of the aluminum plate and improving the grinding effect. Rotating the rotating block 16 drives the screw 15 to move, and the concave frame 8 slides up and down in the groove, which can adjust the height of the upper grinding roller 10 to meet the needs of double-sided grinding of aluminum plates of different thicknesses. The structure is simple, easy to operate, improves grinding efficiency, and enhances the practicality of the device. Starting the forward and reverse motor 22 drives the screw 23 to rotate. The rotation of motor 23 drives two moving blocks 24 with opposite screw directions to move closer or further apart, which can adjust the distance between the two side grinding rollers 14. Then, motor 3 25 is started to drive the side grinding rollers 14 to rotate, so as to meet the purpose of grinding the sides of aluminum plates of different widths and further improve the grinding efficiency. In use, the conveyor 2, motor 1 5, motor 2 12, motor 3 25 and forward and reverse motors 22 are all controlled by the power supply and control switch set on the base 1. The circuits and modules involved are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated.
[0018] Furthermore, the lifting assembly includes a screw 15 and a rotating block 16. One end of the screw 15 extends through to the bottom of the bracket 6 and is rotatably connected to the top of the concave frame 8. The screw 15 is threadedly connected to the bracket 6, and the rotating block 16 is fixedly connected to the top of the screw 15.
[0019] Furthermore, a second movable rod 17 is rotatably connected inside the concave frame 8 near the upper grinding roller 10. A brush roller 18 is sleeved on the second movable rod 17. When the second motor 12 starts, it drives the first rotating shaft 19 and the first movable rod 9 to rotate, so that the upper grinding roller 10 grinds the top surface of the aluminum plate. The rotation of the first rotating shaft 19 drives the conveyor belt 21 to start transmission, which in turn drives the second rotating shaft 20 to rotate synchronously. The rotation of the second rotating shaft 20 drives the brush roller 18 on the second movable rod 17 to rotate, which can clean the surface of the aluminum plate after grinding. A collection cylinder or other container can be placed below the interval plane 3. The brush roller 18 sweeps off the grinding debris on the upper surface of the aluminum plate for unified treatment. The same power source can be used to grind the surface of the aluminum plate and sweep off the debris at the same time, which increases the convenience of using the equipment.
[0020] Furthermore, the corresponding ends of the first movable rod 9 and the second movable rod 17 both extend to the outside of the concave frame 8 and are respectively fixedly connected to a rotating shaft 19 and a rotating shaft 20. The rotating shaft 19 and the rotating shaft 20 are connected to a conveyor belt 21, and the output end of the motor 2 12 is fixedly connected to the rotating shaft 19.
[0021] Furthermore, the moving assembly includes a forward and reverse motor 22, a second screw 23, and a moving block 24. The second screw 23 is rotatably connected between the two side plates 13. A forward and reverse motor 22 is provided on the outer side of either side plate 13. The output end of the forward and reverse motor 22 passes through the inner side of the side plate 13 and is fixedly connected to the second screw 23. Two moving blocks 24 are threadedly connected to the second screw 23. A third motor 25 is fixedly connected to the bottom of each of the two moving blocks 24. The output end of the third motor 25 is fixedly connected to the top of the side grinding roller 14.
[0022] Furthermore, the side of the movable block 24 abuts against the left side of the bracket 6, improving the stability of the lateral movement of the movable block 24.
[0023] Working principle: In use, the aluminum plate is placed on the conveyor 2 on the left side of the base 1. The aluminum plate is conveyed by the conveyors 2 on the left and right sides of the base 1. Starting motor 5 and motor 12 drives the lower grinding roller 4 and the upper grinding roller 10 to rotate simultaneously. The rotation direction of the lower grinding roller 4 and the upper grinding roller 10 is opposite to the movement direction of the aluminum plate, which can grind both sides of the aluminum plate at the same time, improving the grinding effect. Rotating the rotating block 16 drives the screw 15 to move, and the concave frame 8 slides up and down in the slide groove, which can adjust the upper grinding roller 10. The height is adjusted to meet the needs of double-sided grinding of aluminum plates of different thicknesses. The structure is simple, easy to operate, improves grinding efficiency, and enhances the practicality of the device. When the forward and reverse motor 22 is started, it drives the screw 23 to rotate. The rotation of the screw 23 drives the two moving blocks 24 with opposite screw directions to move closer or further apart, which can adjust the distance between the two side grinding rollers 14. Then, the motor 3 25 is started to drive the side grinding rollers 14 to rotate, so as to meet the purpose of grinding the sides of aluminum plates of different widths, further improving the grinding efficiency.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
