[0002] In the field of metal processing, edge grinding is an indispensable process aimed at removing burrs and flash from the edges of metal workpieces to achieve the required dimensional accuracy and surface finish. However, current equipment used for edge grinding of metal workpieces still has some problems.

[0003] The metal polishing process generates a large amount of metal powder. This powder not only pollutes the workshop environment, causing airborne dust that harms workers' respiratory health and can lead to occupational diseases such as pneumoconiosis with long-term inhalation, but also, due to its conductivity, can cause short circuits when it accumulates around electrical equipment, affecting its normal operation. Furthermore, the scattered metal powder accumulates on the ground and in equipment crevices, increasing cleaning difficulty and accelerating equipment wear, thus reducing equipment lifespan.

[0004] As the manufacturing industry moves towards higher precision and greener practices, there is an urgent need for an edge grinding device that can properly handle metal powder, thereby improving metal processing efficiency, ensuring product quality, and protecting worker health and the workshop environment.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Figures 1 to 5 The following is an embodiment of the present invention.

[0024] Example:

[0025] An edge grinding device includes a device body 1, a grinding chamber 2 inside the device body 1, an operation port 3 connected to the grinding chamber 2 on the front side of the device body 1, a grinding assembly installed inside the grinding chamber 2, a dust suction strip 4 installed on the upper wall of the operation port 3, a dust suction groove 5 provided along the length of the lower side of the dust suction strip 4, a dust suction assembly installed on the upper side of the device body 1, and the air inlet of the dust suction assembly connected to the bottom of the dust suction groove 5 through a dust suction pipe 6; an observation port and a transparent plate 7 for sealing the observation port are provided on the upper side of the device body 1. During grinding, the workpiece to be ground is fed into the grinding chamber 2 through the operation port 3, and grinding is performed by the grinding assembly. The dust generated during the grinding process only overflows through the operation port 3. At this time, with the cooperation of the dust suction assembly and the dust suction strip 4, the dust at the operation port 3 is sucked away, thus avoiding the impact of dust overflow on the environment and operators. By incorporating a transparent plate 7 and an observation port, operators can easily observe the workpiece during the grinding process. The dust extraction strip 4 is strategically positioned along the operating port 3, ensuring negative pressure airflow throughout the port and preventing dust spillage. Grinding within the grinding chamber 2 allows most of the dust generated to fall and accumulate naturally due to gravity, facilitating subsequent collection and processing.

[0026] The dust collection assembly includes a dust collection box 8, an air extraction pipe 9, and an exhaust fan 10. The dust collection box 8 is installed on the upper side of the device body 1. Inside the dust collection box 8, a collection chamber 12 and an exhaust chamber 13 are formed by a filter plate 11. One end of the dust extraction pipe 6 is connected to the bottom of the dust collection groove 5, and the other end is connected to the collection chamber 12. One end of the air extraction pipe 9 is connected to the exhaust chamber 13. The exhaust fan 10 is installed inside the air extraction pipe 9. With this configuration, when the exhaust fan 10 is activated, the air extraction pipe 9 draws air out of the air chamber 13, creating a negative pressure. This negative pressure is then absorbed by the filter plate 11, causing the collection chamber 12 to also become negatively pressured. As air enters the collection chamber 12 through the dust collection groove 5 and the dust extraction pipe 6, it also draws in dust near the operating port 3, which is then filtered by the filter plate 11 and accumulates in the collection chamber 12.

[0027] The grinding assembly includes a guide rail 14, a first lead screw motor 16, a second lead screw motor 17, a first movable seat 18, a second movable seat 19, a first grinder, and a second grinder. The guide rail 14 is arranged in the grinding cavity 2 along the left-right direction. The lead screws of the first lead screw motor 16 and the second lead screw motor 17 are both arranged parallel to the guide rail 14. The first movable seat 18 is connected to the drive block of the first lead screw motor 16 and is slidably connected to the guide rail 14. The second movable seat 19 is connected to the drive block of the second lead screw motor 17 and is slidably connected to the guide rail 14. The first grinder is installed on the upper side of the first movable seat 18, and the second grinder is installed on the upper side of the second movable seat 19. With this setup, when grinding a workpiece is required, the workpiece is placed between the first and second grinders. Then, the first and second lead screw motors 16 and 17 drive the first and second grinders to respectively contact both sides of the workpiece for double-sided grinding, or drive only one grinder to contact the workpiece for single-sided grinding. The guide rails 14 provide support for the first and second moving seats 18 and 19, and by limiting their rotation, they allow for smooth left-right movement when the first and second lead screw motors 16 and 17 are activated. Two guide rails 14 can be provided, one on the front and one on the back of the first and second lead screw motors 16 and 17, respectively.

[0028] The first grinder includes a drive motor 20, a driven wheel 21, and a grinding belt 22. A mounting bracket 23 is vertically arranged on the upper side of the first movable base 18. The drive motor 20 is mounted on the mounting bracket 23 near its lower part. The driven wheel 21 is rotatably connected to the mounting bracket 23 above the drive motor 20. A drive wheel 24 is mounted on the output shaft of the drive motor 20. The grinding belt 22 is fitted onto the drive wheel 24 and the driven wheel 21. By starting the drive motor 20, the drive wheel 24 drives the grinding belt 22 to move at high speed, thereby grinding the surface of the workpiece. The driven wheel 21 can be used to taut and tighten the grinding belt 22.
