DETAILED DESCRIPTION

[0077] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0078] The damper often needs to cover certain cylindrical outer ring surface parts, horizontal surface parts, certain side surface inclined parts (the outer ring surface length gradually expands from top to bottom), and damper and hanger connecting parts during spraying.

[0079] As Figures 1-12As shown in the figure, this embodiment proposes a rust-proof coating spraying device for vibration damper processing, including a base plate 1 and a spraying machine 2. The base plate 1 is composed of two vertical plates on both sides and a horizontal plate at the bottom. Several spraying machines 2 are provided, and the spraying machines 2 are mounted on the horizontal plate of the base plate 1 by a mounting bracket.

[0080] It also includes an eccentric winding mechanism;

[0081] The eccentric winding mechanism includes,

[0082] A rotation drive assembly is mounted on the base plate 1.

[0083] Two fixing plates 25 are provided and are mounted on the rotation drive assembly.

[0084] The feeding drum 26 is detachably mounted between the two fixed plates 25 via a rotating shaft.

[0085] The first roller 27 is rotatably mounted between the two fixed plates 25 via a rotating shaft. The first roller 27 contacts the outer ring surface of the shock absorber and causes the covering film to wrap around the surface of the shock absorber.

[0086] A winding control mechanism is mounted on the rotation drive assembly, which controls the first roller 27 to wind the covering film thereon onto the vibration damper.

[0087] In this embodiment, the vibration damper is mounted on the hanger, which drives the vibration damper to move above the eccentric winding mechanism. The eccentric winding mechanism rises, causing the first roller 27 and the unloading drum 26 to rise. The winding control mechanism causes the first roller 27 to rotate, so that the first roller 27 can contact the area to be covered by the vibration damper. The first roller 27 presses the end of the covering film onto the surface of the vibration damper. Then, the winding control mechanism rotates around the vibration damper under the drive of the rotation drive assembly, winding the covering film onto the vibration damper, thereby achieving the covering of the required surface of the vibration damper.

[0088] like Figures 3-4 As shown, it also includes a lifting mechanism, which includes,

[0089] There are two first slide rails 3, which are symmetrically installed on the horizontal plate of the base plate 1.

[0090] There are two first electric sliders 5, which are respectively slidably disposed within two first slide rails 3.

[0091] When the hanger drives the shock absorber to move above the eccentric winding mechanism, the two first electric sliding blocks 5 slide upward in the two first sliding rails 3, and the upward movement of the first electric sliding blocks 5 makes the eccentric winding mechanism and the winding control mechanism rise synchronously, so that the first roller 27 and the required covering part of the shock absorber are at the same height, facilitating the subsequent covering of the shock absorber.

[0092] As shown in Figures 3-5 , the eccentric winding mechanism further comprises a support assembly, the support assembly comprises,

[0093] a mounting frame 6, the mounting frame 6 is a rectangular frame structure, the mounting frame 6 is mounted on the two first electric sliding blocks 5,

[0095] a guide block 8, four guide blocks 8 are provided, and the four guide blocks 8 are installed on the four support legs 7.

[0098] a straight rack 10, two straight racks 10 are provided, and the two straight racks 10 are respectively installed at the telescopic ends of the two telescopic drive columns 9, the straight rack 10 is in a horizontal direction, and the two straight racks 10 are respectively slidingly arranged on a second group of guide blocks 8 without the telescopic drive column 9,

[0103] A rotating disc 17 is rotatably mounted on the bearing seat 16.

[0104] In this embodiment, the covering of the eccentric position where the hanger is connected to the shock absorber is started after the covering of the cylindrical outer surface of the shock absorber is completed. At this time, the extension and retraction of the telescopic drive column 9 causes the straight rack 10 to move back and forth, the movement of the straight rack 10 causes the ring gear 13 to swing, the swing of the ring gear 13 causes the sector bracket 12 to swing synchronously, the swing of the sector bracket 12 causes the rotating shaft 11 to rotate, the rotation of the rotating shaft 11 causes the winding control mechanism to swing in the mounting frame 6, the swing of the winding control mechanism causes the first roller 27 to swing synchronously, and the swing of the first roller 27 causes the covering film to be obliquely wound to the position where the hanger is connected to the shock absorber, so that the covering film can also be wound to the connection point of the hanger and the shock absorber, thereby achieving the covering of the connection point of the hanger and the shock absorber.

[0105] As shown in Figures 8-10 the winding control mechanism comprises,

[0106] a power assembly mounted on the rotating drive assembly,

[0107] a support plate 19 mounted on the rotating disc 17,

[0116] A first motor 14 is installed on the fan-shaped support 12 through a motor box,

[0118] A tooth ring 18 is installed on the rotating disc 17, the tooth ring 18 is located below the bearing seat 16, and the tooth ring 18 is engaged with the first gear 15.

[0119] As shown in Figures 1-2 the winding control mechanism further comprises a cutting assembly, the cutting assembly comprises,

[0120] A second sliding rail 30 is installed between the two fixed plates 25,

[0121] A second motorized sliding block 31 is slidably arranged in the second sliding rail 30,

[0122] A cutting knife 32 is rotatably installed on the second motorized sliding block 31, and the cutting knife 32 faces the first roller 27.

[0123] In this embodiment, the covering film is installed on the feed roll 26 by hand, and the covering film opening is passed through the gap between the first roller 27 and the second roller 28 so that the covering film is attached to the first roller 27, and the passing-in direction of the covering film should be from the gap between the first roller 27 and the second roller 28 on the side away from the cutting knife 32. When the damper is moved to the upper side of the eccentric winding mechanism with the hanger, the lifting mechanism drives the mounting frame 6 to move upward, and the upward movement of the mounting frame 6 drives the rotating shaft 11 to move upward, so that the carrier seat 16 and the swivel plate 17 are lifted. When the swivel plate 17 is lifted to the same height as the required covering outer ring surface of the damper, the first rotating shaft 24 is rotated toward the damper by the power provided by the second electric rotating shaft seat 23, the first rotating shaft 24 is rotated to drive the fixed plate 25 to rotate, the fixed plate 25 is rotated to drive the first roller 27 to gradually approach the damper, so that the covering film port on the first roller 27 can be closely attached to the cylindrical outer ring surface of the damper.

After the covering of the cylindrical outer ring surface of the damper is completed, the first rotating shaft 24 is rotated away from the damper by the power provided by the second electric rotating shaft seat 23. Then, the damper and the hanger connection part are covered under the driving of the first motor 14 and the swing of the swivel plate 17. When the covering of the damper and the hanger connection part is completed, the cutting knife 32 is rotated to make the cutting edge face the first roller 27. Then, the cutting knife 32 is driven by the second electric sliding block 31 to slide on the second sliding rail 30, so that the covering film is broken. At this time, the opening of the cut covering film is located on the surface of the first roller 27 close to the second roller 28. Then, the cutting knife 32 is rotated to make the cutting edge away from the first roller 27. Then, the first roller 27 is rotated by the power provided by the third electric rotating shaft seat 29, and the cooperation with the second roller 28 makes the port of the covering film be pulled and transmitted close to the damper, so as to cover the next damper.

[0124] When the covering of the horizontal part of the shock absorber is completed, the first electric sliding block 5 slides downward in the first sliding rail 3 to make the mounting frame 6 move downward, at this time, the rotating column 21 rotates under the driving force of the first electric rotating shaft base 20, the rotating column 21 rotates to make the first connecting plate 22 rotate, the first connecting plate 22 rotates to make the fixed plate 25 rotate under the restriction of the first rotating shaft rod 24, the fixed plate 25 rotates to make the first roller 27 overturn by 90 degrees, at this time, the opening of the covering film is upward, the first roller 27 moves downward under the driving of the lifting mechanism, so that the covering film contacts the inclined part of the shock absorber, then the first rotating shaft rod 24 rotates under the rotation of the second electric rotating shaft base 23, the first rotating shaft rod 24 rotates to make the fixed plate 25 rotate, the fixed plate 25 rotates to make the first roller 27 move obliquely upward, so that the first roller 27 always contacts the inclined part of the shock absorber, and the covering film is cut by the cutting knife 32 after the covering of the inclined part is completed, so that the covering of the inclined part of the upper side of the shock absorber is realized.

[0125] As shown in Figures 8-11 , the horizontal winding control mechanism is further provided with a pushing assembly,

[0126] a first guide rail 33 which is obliquely arranged on the side of the fixed plate 25 close to the cutting knife 32,

[0127] a third sliding rail 34 which is arranged on the fixed plate 25.

[0128] As shown in Figures 8-12 , the horizontal winding control mechanism further comprises a pushing assembly, the pushing assembly comprises,

[0129] a sliding plate 36 which is slidingly arranged in the third sliding rail 34, both sides of the sliding plate 36 are provided with slide plates, and a rectangular notch is formed in the bottom of the end of the sliding plate 36 close to the first roller 27,

[0130] an oblique pushing plate 37 which is obliquely arranged on the end of the sliding plate 36 close to the first roller 27,

[0131] an elastic telescopic rod 38 which is arranged in the notch position of the sliding plate 36, and the telescopic end of the elastic telescopic rod 38 is directed to the first roller 27,

[0132] a limiting pressing block 39 which is arranged at the telescopic end of the elastic telescopic rod 38, the top of the limiting pressing block 39 is slidingly connected to the bottom of the sliding plate 36, and a notch is formed in the end of the limiting pressing block 39 close to the first roller 27,

[0133] a second guide rail 40 which is vertically arranged on the sliding plate 36,

[0134] An electric telescopic rod 35 is installed on the fixed plate 25, and the telescopic end of the electric telescopic rod 35 is connected to the second guide rail 40.

[0135] As shown in Figures 8-10 , it further comprises,

[0136] A second guide rail 40 is vertically installed on the sliding plate 36,

[0137] A sliding card column 41 is composed of a rectangular block and a cylinder, the sliding card column 41 is slidably arranged in the slide of the first guide rail 33 through the rectangular block, and the sliding card column 41 is slidably arranged in the second guide rail 40 through the cylinder,

[0138] A movable plate 42 is fixedly connected to the sliding card column 41, and the movable plate 42 is located on the sliding card column 41 between the second guide rail 40 and the first guide rail 33,

[0139] An elastic gasket 4 is installed at the bottom of the movable plate 42.

[0140] When the covering of the connection between the damper and the hanger is completed, the upper horizontal surface of the damper needs to be covered. When the covering film on the first roller 27 contacts the side wall of the horizontal surface, the electric telescopic rod 35 is then extended to push the second guide rail 40 to move towards the damper, and the movement of the second guide rail 40 makes the sliding plate 36 slide in the third slide rail 34 towards the damper. The movement of the sliding plate 36 makes the oblique push plate 37 move towards the damper, and the movement of the sliding plate 36 makes the limiting block 39 move towards the damper under the restriction of the elastic telescopic rod 38. When the gap of the limiting block 39 contacts the side wall and the upper surface of the damper, the limiting block 39 pushes the covering film onto the upper horizontal surface of the damper, ensuring the complete adhesion of the edge of the upper surface covering film. At this time, the sliding plate 36 moves towards the damper, and the elastic telescopic rod 38 is contracted. When the second guide rail 40 moves, the sliding block 41 can only move in the first guide rail 33 due to the restriction of the first guide rail 33 on the sliding block 41. The movement of the sliding block 41 in the first guide rail 33 makes the movable plate 42 move downwards, and the movement of the movable plate 42 downwards makes the elastic gasket 4 move downwards. The movement of the oblique push plate 37 towards the damper and the movement of the elastic gasket 4 towards the horizontal part of the damper make the oblique push plate 37 push the covering film downwards and the elastic gasket 4 press the covering film onto the horizontal surface, so that the junction between the horizontal surface and the cylindrical outer surface can be covered by the covering film. Then, the first roller 27 rotates around the damper to cover the horizontal part of the damper, thereby realizing the omnibearing covering of the horizontal part of the damper.

[0141] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
