Description

Technical Field

[0002] Hardware is a tool made of metal materials, covering categories such as locks, handles, door and window accessories, and bathroom accessories. It is widely used in building decoration, home equipment and industrial production.

[0003] To improve the corrosion resistance and aesthetics of tubular hardware, it is usually necessary to spray paint on its surface. Existing spraying equipment is mostly automatic. When spraying cylindrical tubular hardware, in order to ensure the stability of the spraying process, the tubular hardware needs to be fixed. This causes the spraying assembly to be unable to effectively spray the clamping position of the fixture, requiring subsequent touch-up spraying, which affects the spraying efficiency of tubular hardware. At the same time, when spraying tubular hardware once, the automatic spraying device can only spray half of it. One tubular hardware needs to be sprayed twice, further affecting the spraying efficiency of tubular hardware.

[0004] Therefore, we provide a paint spraying device for tubular hardware. Utility Model Content

[0025] Example: A paint spraying device for tubular hardware, such as Figures 1-4 As shown, the system includes a spraying machine 1, which has a spraying assembly 2 inside. Two fixing blocks 3 are symmetrically arranged below the spraying assembly 2. Support blocks 4 are installed above the two fixing blocks 3. Two rotating positioning columns 5 are symmetrically arranged above the support blocks 4. A tubular hardware component 6 is arranged between the two rotating positioning columns 5. Two fixed connecting blocks 7 are symmetrically arranged outside the tubular hardware component 6. A clamping block 8 is rotatably arranged inside the fixed connecting block 7. Telescopic blocks 9 are rotatably connected to the lower half of the clamping block 8 on both opposite sides. Screw barrels 14 are rotatably connected to the adjacent sides of the two telescopic blocks 9. A screw rod 13 is threadedly connected inside the screw barrel 14.

[0026] Two fixed blocks 3 are simultaneously fixedly connected to the inner wall of the sprayer 1. The two opposite ends of the two rotating positioning columns 5 are rotatably connected to the inner wall of the sprayer 1. One end of one rotating positioning column 5 extends out of the outside of the sprayer 1. A first motor 11 is installed on the outer surface of the sprayer 1. The outer end of one rotating positioning column 5 is fixedly connected to the output end of the first motor 11.

[0027] The outer surface of the tubular hardware 6 is simultaneously in contact with the outer surfaces of the two rotating positioning columns 5. The fixed connecting block 7 is fixedly installed on the outer surface of the support block 4. The clamping block 8 is arranged in an inverted L shape. The upper half of the clamping block 8 is rotatably equipped with a rotating roller 10. The outer surface of the rotating roller 10 is in contact with the outer surface of the tubular hardware 6.

[0028] Protective cylinders 12 are inserted through both ends of the fixed block 3. The adjacent ends of the two protective cylinders 12 are fixedly connected. The lower end of the telescopic block 9 is inserted into the protective cylinder 12. The telescopic block 9 and the protective cylinder 12 are slidably connected. The screw cylinder 14 slides inside the protective cylinder 12. The two screw cylinders 14 are always symmetrically distributed.

[0029] The two screws 13 are symmetrically distributed, and the adjacent ends of the two screws 13 are fixedly connected. A second motor 15 is fixedly installed on the inner wall of one side of the protective cylinder 12.

[0030] One end of one screw 13 is rotatably connected to the inner wall of the protective cylinder 12, and one end of the other screw 13 is fixedly connected to the output end of the second motor 15.

[0031] When the spraying machine 1 applies paint to the tubular hardware 6, the tubular hardware 6 is fixed in place, and then the spraying assembly 2 sprays the tubular hardware 6. At this time, the spraying assembly 2 can only spray half of the surface of the tubular hardware 6. It is necessary to fix the tubular hardware 6 again and spray the other half of the tubular hardware 6 again through the spraying assembly 2 to complete the overall spraying of the tubular hardware 6. This process is a known existing technology. However, during the spraying process, there is a problem that the tubular hardware 6 cannot be completely coated. To achieve a complete one-time spraying of the tubular hardware 6, and to address situations where effective spraying is not possible at the connection between the tubular hardware 6 and the fixture, a rotating positioning column 5, a clamping block 8, and a rotating roller 10 are used to clamp and drive the tubular hardware 6. To prevent the spraying material from affecting the normal operation of the component, the exposed areas of the component are shielded with a masking cloth, ensuring that the normal operation of the component is not affected. Then, to ensure the stability of the tubular hardware 6 during the spraying process, the tubular hardware 6 must be clamped and fixed. First... The tubular hardware 6 is placed between two rotating positioning posts 5. The two rotating positioning posts 5 provide initial support and positioning for the tubular hardware 6. To prevent the tubular hardware 6 from moving upwards, the upper part of the tubular hardware 6 needs to be fixed. When the second motor 15 is running, the two screws 13 will rotate synchronously inside the protective cylinder 12, thereby driving the screw cylinder 14 to slide inside the protective cylinder 12. When the two screw cylinders 14 move outwards at the same time, the screw cylinders 14 will drive the telescopic block 9 to move simultaneously, and the telescopic block 9 will drive the clamping... The lower half of block 8 rotates outward in an arc shape, while the upper half of clamping block 8 rotates in an arc shape inward around the point where clamping block 8 intersects with fixed connecting block 7, until rotating roller 10 is in contact with the outer surface of tubular hardware 6, thus completing the clamping and fixing of tubular hardware 6. During this process, when the lower half of clamping block 8 rotates in an arc shape, the height of the lowest end of clamping block 8 will change synchronously, while the position of screw 13 cannot be moved. Therefore, telescopic block 9 is telescopic to ensure the normal operation of clamping block 8.

[0032] To ensure that the spraying assembly 2 can fully spray the tubular hardware 6 in one go, the tubular hardware 6 needs to be rotated. The first motor 11 drives a rotating positioning column 5 to rotate. Under the action of close contact and the rotation of the rotating positioning column 5 and the rotating roller 10, the rotating positioning column 5 will push the tubular hardware 6 to rotate, thereby ensuring the spraying effect of the spraying assembly 2 on the tubular hardware 6.

[0033] Under the driving and positioning action of the rotating positioning column 5 and the first motor 11, and with the clamping and positioning action of the clamping block 8 and the rotating roller 10, firstly, the tubular hardware 6 can be driven to rotate during the clamping process, ensuring that the outer surface of the tubular hardware 6 can be fully sprayed at one time, further improving the spraying efficiency of the spraying component 2. Secondly, the clamping range of the tubular hardware 6 can be sprayed synchronously, avoiding the need for re-spraying later, further ensuring the single-spraying efficiency of the tubular hardware 6. Finally, it can clamp and spray tubular hardware 6 of different specifications, further improving the spraying application range of the spraying component 2.

[0034] like Figure 3 As shown, two limiting blocks 16 are symmetrically arranged between the two rotating positioning columns 5. The lower end of the limiting block 16 is simultaneously slidably connected to the lower end of the two fixed blocks 3. The tubular hardware 6 is located between the two limiting blocks 16.

[0035] When the tubular hardware 6 rotates between the rotating positioning column 5 and the rotating roller 10, in order to prevent the rotating roller 10 from moving left and right, which would prevent the spraying assembly 2 from accurately spraying the surface of the tubular hardware 6, two limiting blocks 16 are set on the outside of the tubular hardware 6. The limiting blocks 16 limit the movement range of the tubular hardware 6, ensuring the stability of the relative position of the tubular hardware 6 during rotation. Since the lower end of the limiting block 16 is tightly fitted at the connection position with the spraying assembly 2, there is a certain friction between the limiting block 16 and the spraying assembly 2, which can further ensure the stability of the relative position of the limiting block 16 during operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
