Description

Technical Field

[0001] This utility model relates to the field of door handle processing technology, specifically to a brushing device for the surface of an appliance door handle. Background Technology

[0002] Brushed finish is a process that uses physical friction, such as sandpaper or brushing wheels, to create a uniform texture on the surface of a metal door handle. This process not only enhances the aesthetics of the door handle (giving it a minimalist or retro feel), but also improves its practicality by increasing surface friction, while also providing some scratch resistance and protecting the surface.

[0003] Currently, traditional door handle wire drawing devices still have some shortcomings. Some devices adopt a single-station processing mode, which requires frequent manual loading and unloading, resulting in long downtime and making it difficult to meet the needs of mass production. If the metal dust generated during the wire drawing process is not collected in time, it will not only pollute the working environment, but may also affect the operating accuracy of the equipment and the health of the operators.

[0021] Example 1: A brushing device for the surface of an appliance door handle includes a processing box 1 and a handle 19. A support block 2 is fixedly connected between the two inner side walls of the processing box 1. A rotating rod 3 is rotatably mounted on the upper surface of the support block 2. A rotating disk 4 is fixedly connected to the top of the rotating rod 3. A ring of placement blocks 5 is fixedly connected to the upper surface of the rotating disk 4. A set of positioning rods 6 is fixedly connected to the upper surface of each placement block 5. An movable groove 20 is opened on the surface of the processing box 1.

[0022] Two electric push rods 7 are fixedly installed on the upper surface of the processing box 1. The output ends of the two electric push rods 7 extend into the interior of the processing box 1 and are fixedly connected to a support frame 8. A wire drawing assembly is provided inside the support frame 8.

[0023] Example 2: The difference between this example and Example 1 is that the wire drawing assembly includes two pulleys 9, and a wire drawing abrasive belt 10 is provided on the two pulleys 9. A drive assembly is provided on the side of the support frame 8, and the drive assembly can provide power to the two pulleys 9 to drive the wire drawing abrasive belt 10 to rotate.

[0024] Example 3: The difference between this example and Example 1 is that the first motor 11 is fixedly installed on the lower surface of the support block 2, and the bottom end of the rotating rod 3 passes through the support block 2 and is fixedly connected to the output end of the first motor 11.

[0025] Example 4: The difference between this example and Example 1 is that a collection box 12 is fixedly installed on the upper surface of the processing box 1, and an exhaust fan 13 is provided on the collection box 12. The exhaust fan 13 is connected to the collection box 12, and an air inlet pipe 14 is connected to one side of the collection box 12.

[0028] In summary, the brushed surface device for appliance door handles, when in use, involves placing the handle requiring brushing onto multiple placement blocks 5 on the rotating disk 4, inserting the two positioning rods 6 into the mounting holes of the handle 19 to fix and limit the handle. Then, the rotation of the first motor 11 drives the rotating disk 4 and the handle 19 to rotate, causing the handle 19 to rotate below the brushing assembly. The extension of the electric push rod 7 then causes the support frame 8 and the brushing abrasive belt 10 to descend, disengaging the brushing abrasive belt 10 from the handle 19. Simultaneously, the drive assembly rotates the brushing abrasive belt 10, thus brushing the handle 19. The surface of the handle 19 is wire-drawn, and the dust generated during the wire-drawing process is absorbed by the exhaust fan 13. After the wire-drawing process of one handle 19 is completed, the electric push rod 7 drives the support frame 8 to rise, and then the first motor 11 rotates to drive the unprocessed handle 19 to continue to move to the bottom of the wire-drawing assembly. The processed handle 19 is moved to the outside of the processing box 1, and then it can be removed and a new handle 19 to be processed can be placed, realizing cyclic operation and reducing downtime. When using this device, the handle 19 can be quickly wire-drawn, while reducing downtime and improving efficiency.
