Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a self-rotating paint spraying device for spring processing. Background Art

[0002] A spring is a mechanical component that utilizes elasticity to function. Made of elastic material, it deforms under external force and returns to its original shape when the force is removed. It is also called a "spring." It is typically made of spring steel. There are many different types of springs, primarily categorized by shape, including coil springs, scroll springs, leaf springs, and special-shaped springs.

[0003] During the spring processing process, to extend the spring's service life and ensure its performance, the spring needs to be painted. Currently, most painting devices have a simple structure. During the painting process, the spring cannot rotate on its own, requiring manual rotation or multiple spraying. Otherwise, the paint on the rear surface of the spring is uneven, resulting in poor paint quality. Furthermore, manual rotation of the spring can easily cause wet paint to adhere to hands. Therefore, we proposed a self-rotating spring painting device to address these issues. Utility Model Content

[0004] The utility model provides a self-rotating spring painting device for processing springs to address the defects in the prior art that the spring cannot rotate by itself during the painting process and needs to be rotated manually or the spring needs to be sprayed multiple times, otherwise the paint on the rear surface of the spring will be uneven and the paint quality will be poor.

[0010] In a preferred embodiment of the present invention, the number of the installation stations is six, and the installation stations are evenly distributed around the center of the turntable, and a controller is provided on one side of the variable frequency motor. The controller controls the variable frequency motor to drive the turntable to rotate 60° and then stop for 10-15 seconds.

Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0021] like Figure 1-3 The self-rotating spring processing paint spraying device shown includes a support base 1 and a paint bucket 18. A rotating table 3 is mounted on the support base 1. The rotating table 3 is indirectly driven by a variable frequency motor 2 mounted on the support base 1. A plurality of spring installation stations 4 are provided on the upper surface of the rotating table 3. The number of installation stations 4 is six and the installation stations 4 are evenly distributed around the center of the rotating table 3. The installation stations 4 include a rotating shaft 41 rotatably mounted on the rotating table 3. The outer wall of the rotating shaft 41 is provided with a blade 43. The top of the rotating shaft 41 is provided with a clamping seat 42, and the outer wall of the clamping seat 42 is provided with a rotating ring 44.

[0022] Among them, a support frame 5 is provided on one side of the rotating table 3, and a mounting beam 6 is fixed on the upper end of the support frame 5. A paint tube 7 is provided on the mounting beam 6. The paint tube 7 is vertically arranged. Figure 1 As shown, the paint pipe 7 is located above the rotating platform 3. When the rotating platform 3 rotates, the installation station 4 is between the support frame 5 and the paint pipe 7. A plurality of paint spray heads 8 are provided on the paint pipe 7. The paint spray heads 8 are linearly arranged in the upper and lower directions. The bottom end of the paint pipe 7 is provided with a paint inlet pipe 15 connected to a paint bucket 18. The paint bucket 18 is externally equipped with a paint pump, which draws paint through the paint pump and transports it to the paint pipe 7.

[0023] Specifically, a base plate 11 is laterally provided at the lower end of the paint tube 7, and the base plate 11 separates the upper and lower ends of the paint tube 7, and an extrusion plate 12 is inserted at one end of the base plate 11, and the extrusion plate 12 is slidably connected to the base plate 11, and an extrusion spring 14 is fixed between the extrusion plate 12 and the inner end of the base plate 11, and a connecting hole 13 for connecting the upper and lower ends of the paint tube 7 is provided through the extrusion plate 12, the extrusion plate 12 and the swivel 44 are on the same horizontal plane, and both sides of the outer end of the extrusion plate 12 are provided with an inclination angle, which makes it easier for the swivel 44 to push the extrusion plate 12 so that the connecting hole 13 connects the upper and lower ends of the paint tube 7;

[0024] At the same time, an adjusting plate 9 is inserted at the top end of the paint tube 7, and the adjusting plate 9 is slidably connected to the paint tube 7, and an adjusting screw rod 10 is inserted at the top end of the adjusting plate 9, and the adjusting screw rod 10 is threadedly connected to the adjusting plate 9, and the adjusting screw rod 10 passes through the support frame 5 and is rotatably connected to the support frame 5. By rotating the adjusting screw rod 10, the adjusting plate 9 is driven to slide in the paint tube 7, and part of the paint spray head 8 is covered, so that springs of different heights can be sprayed with paint, reducing paint waste.

[0025] It should be noted that a controller is provided on one side of the variable frequency motor 2, which controls the variable frequency motor 2 to drive the rotating table 3 to rotate 60° and then stop for 10-15 seconds. When the rotating table 3 stops, the rotating ring 44 pushes the extrusion plate 12, and the upper and lower ends of the paint tube 7 are connected through the connecting hole 13, so that the paint spray head 8 works to spray paint on the spring.

[0026] Furthermore, it also includes an adsorption bin 16 fixed on the support frame 5, and a dust suction fan 17 is installed on the support base 1.

[0028] The springs are installed on the clamping seat 42 in sequence, and the frequency conversion motor 2 drives the rotating table 3 to rotate. When the rotating table 3 rotates, it drives the installation station 4 to rotate. When the swivel 44 pushes the extrusion plate 12 and connects the upper and lower ends of the paint tube 7 through the connecting hole 13, the frequency conversion motor 2 stops for 10 seconds. At this time, the paint spraying head 8 sprays the spring. During the painting process, the air nozzle 19 blows the blade 43, driving the clamping seat 42 to rotate, thereby driving the spring to rotate, so as to facilitate comprehensive spraying of the spring and improve the spraying quality.
