[0002] In metal workpiece processing, surface polishing and grinding are key steps to improve the appearance quality and performance of metal workpieces.

[0003] Polishing and grinding of metal workpieces is performed using polishing and grinding machines. However, in existing polishing and grinding machines, the dust generated after polishing accumulates on the surface of the metal workpiece. During unloading, the dust needs to be manually wiped away to prevent it from flying and affecting the working environment. Manual dust removal is inefficient, and the edges of polished workpieces are often sharp, posing a risk of injury when handling them manually. Therefore, this invention proposes a metal workpiece surface polishing and grinding machine to address the shortcomings of existing technologies. Utility Model Content

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] Example 1

[0021] according to Figure 1-4 As shown, this embodiment proposes a metal workpiece surface polishing and grinding machine, including a lifting base 1, a machine base 2, an active sanding belt wheel 3, a driven sanding belt wheel 4, and a feeding conveyor belt 5. The lifting base 1 is provided with the machine base 2 at the top. The active sanding belt wheel 3 is provided below one side wall of the machine base 2 via a first mounting shaft. The first mounting shaft is driven by a polishing and grinding motor 6. The driven sanding belt wheel 4 is provided on the machine base 2 above the active sanding belt wheel 3 via a second mounting shaft. A polishing and grinding sanding belt 7 is connected to the active sanding belt wheel 3 and the driven sanding belt wheel 4. The feeding conveyor belt 5 is provided directly below the active sanding belt wheel 3. A dust collection box 8 is provided above the discharge end of the feeding conveyor belt 5. A vacuum cleaner 9 is provided on the dust collection box 8. The vacuum cleaner 9 is connected to the side wall of the machine base 2 via a connecting mechanism. The top of the dust collection box 8 is symmetrically provided with through grooves 10. The first suction port 901 and the second suction port 902 of the vacuum cleaner 9 extend from the through grooves 10 into the interior of the dust collection box 8.

[0022] When the metal workpiece surface polishing and grinding machine of this utility model is in operation, the metal workpiece (flat workpiece) is placed on the feeding conveyor belt 5 for feeding. When the metal workpiece enters under the active sanding belt wheel 3, the active sanding belt wheel 3 driven by the polishing and grinding motor 6 will drive the driven sanding belt wheel 4 to rotate through the polishing and grinding belt 7, so that the polishing and grinding belt 7 does not contact the metal workpiece for grinding. After the polishing is completed, the metal workpiece enters the dust collection box 8. After the vacuum cleaner 9 is started, the dust on the surface of the metal workpiece is sucked up through the first dust suction port 901 and the second dust suction port 902 respectively. In this process, the first dust suction port 901 performs the initial dust suction, and then the second dust suction port 902 performs the secondary dust suction. The two dust suctions improve the dust suction effect.

[0023] The machine base 2 has mounting seats 11 on both sides of its lower end. A limiting roller 12 is rotatably mounted on each mounting seat 11, and the width of the limiting roller 12 is adapted to the width of the feeding conveyor belt 5. By setting the limiting roller 12, the movement of the metal workpiece on the feeding conveyor belt 5 can be limited, ensuring that the metal workpiece smoothly enters below the active abrasive belt wheel 3 for grinding and polishing. The position of the limiting roller 12 on the mounting seat 11 is adjustable, thus adapting to grinding and polishing operations of metal workpieces of different thicknesses.

[0024] The lifting seat 1 includes a base 101, a lifting cylinder 102, and a guide plate 103. The lifting cylinder 102 is located on the top of the base 101, and its output end is connected to the bottom of the base 2. The guide plates 103 are symmetrically arranged on the top of the base 101, and the inner sidewall of the bottom of the base 2 is slidably connected to the guide plates 103. When adjusting the lifting position of the lifting seat 1, the lifting cylinder 102 extends to drive the base 2 to rise. During this process, the inner sidewall of the bottom of the base 2 is slidably connected to the guide plates 103, thereby improving the lifting stability of the base 2.

[0025] The connecting mechanism includes a connecting plate 13 and fixing bolts 14. One end of the connecting plate 13 is connected to the side wall of the base 2, and the vacuum cleaner 9 is fixed to the connecting plate 13 by the fixing bolts 14. An auxiliary support plate 15 is provided on the top of the dust collection box 8, and a guide groove 16 is provided on the auxiliary support plate 15. One end of the connecting plate 13 is slidably connected to the guide groove 16. When the base 2 is adjusted in height on the lifting seat 1, the vacuum cleaner 9 can be lifted synchronously through the connecting mechanism. During the lifting process, one end of the connecting plate 13 is slidably connected to the guide groove 16, thereby improving the lifting stability.

[0026] This invention features a dust collection box 8 located above the discharge end of the feeding conveyor belt 5, with a vacuum cleaner 9 mounted on the dust collection box 8. The first and second suction ports 901 and 902 of the vacuum cleaner 9 extend from the through groove 10 at the top of the dust collection box 8 into its interior. Dust accumulated on the surface of the metal workpiece after polishing is sucked away and cleaned as it enters the dust collection box 8. No manual cleaning of the metal workpiece is required after discharge, effectively improving the polishing and grinding machine's performance and preventing accidental injury by avoiding manual handling of the workpiece. The machine base 2 is mounted on a lifting seat 1. The polishing component, consisting of an active sanding wheel 3, a driven sanding wheel 4, a polishing belt 7, and a polishing motor 6, can polish metal workpieces of varying thicknesses. The vacuum cleaner 9 is connected to the side wall of the machine base 2 via a connecting mechanism, allowing the height difference between the first and second suction ports 901 and 902 and the feeding conveyor belt 5 to be adjusted synchronously when polishing workpieces of different thicknesses, providing high flexibility.

[0027] Example 2

[0028] according to Figure 1-4 As shown, this embodiment proposes a metal workpiece surface polishing and grinding machine, including a lifting base 1, a machine base 2, an active sanding belt wheel 3, a driven sanding belt wheel 4, and a feeding conveyor belt 5. The lifting base 1 is provided with the machine base 2 at the top. The active sanding belt wheel 3 is provided below one side wall of the machine base 2 via a first mounting shaft. The first mounting shaft is driven by a polishing and grinding motor 6. The driven sanding belt wheel 4 is provided on the machine base 2 above the active sanding belt wheel 3 via a second mounting shaft. A polishing and grinding sanding belt 7 is connected to the active sanding belt wheel 3 and the driven sanding belt wheel 4. The feeding conveyor belt 5 is provided directly below the active sanding belt wheel 3. A dust collection box 8 is provided above the discharge end of the feeding conveyor belt 5. A vacuum cleaner 9 is provided on the dust collection box 8. The vacuum cleaner 9 is connected to the side wall of the machine base 2 via a connecting mechanism. The top of the dust collection box 8 is symmetrically provided with through grooves 10. The first suction port 901 and the second suction port 902 of the vacuum cleaner 9 extend from the through grooves 10 into the interior of the dust collection box 8.

[0029] The dust collection box 8 has a slide rail 17 on its front side, and a transparent baffle 18 is slidably connected to the slide rail 17. By setting the transparent baffle 18 slidably connected to the slide rail 17 on the front side of the dust collection box 8, this utility model can shield the sparks and dust generated during the polishing process of the polishing components consisting of the active sanding wheel 3, the driven sanding wheel 4, the polishing belt 7, and the polishing motor 6, thus preventing injury.
