DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 7 As shown, a high-adhesion coating device for a metal ring gasket of the present invention comprises: a box body 10, a spraying assembly, a rotating rod 20, an annular gasket 23, a variable pitch thread 21, a support assembly, a support group 1 and a support group 2, the rotating rod 20 is rotatably arranged on the top of the box body 10, the spraying assembly is arranged on the top of the box body 10 and is located on both sides of the rotating rod 20, the spraying assembly can spray the coating on the metal ring gasket, the variable pitch thread 21 is arranged on the outer peripheral surface of the rotating rod 20 and is arranged along the axial direction of the rotating rod 20, the annular gasket 23 is arranged on the outer peripheral surface of the rotating rod 20, and the annular gasket 23 has a plurality of them, and the annular gasket 23 and The variable pitch threads 21 cooperate with each other so that the annular gasket 23 can move evenly and diffusely along the axial direction of the rotating rod 20. A circular cylinder 24 is rotatably arranged on each circular gasket 23. Multiple support assemblies are correspondingly arranged on the outer circumference of each circular cylinder 24. Each support assembly corresponds to an circular cylinder 24. The support assembly includes support group 1 and support group 2. Support group 1 and support group 2 are symmetrically arranged on the outer circumference of the circular cylinder 24. The support assembly can eccentrically expand the metal ring gasket to be sprayed. Support group 1 and support group 2 on two adjacent circular cylinders 24 are swapped, so that the metal ring gaskets are staggered and stacked.

[0039] When spraying the metal ring gasket, firstly, the metal ring gasket is sleeved on the rotating rod 20, and multiple metal ring gaskets are in a stacked state, and then the support component expands each metal ring gasket. Since the support lengths of support group one and support group two are inconsistent, the metal ring gasket is expanded eccentrically with respect to the axis of the rotating rod 20, and adjacent metal ring gaskets are in a staggered stacked state after expansion, so that the spraying component can evenly spray the upper and lower surfaces and the facades of multiple metal ring gaskets, thereby improving the spraying efficiency.

[0040] The rotation of the rotating rod 20 can drive the annular gasket 23 to move upward and spread evenly. The movement of the annular gasket 23 drives the annular cylinder 24 to move. The movement of the annular cylinder 24 drives the supporting assembly and the metal ring gasket to move, so that each metal ring gasket is evenly spaced and distributed, so that the sprayed paint can be evenly diffused to the spraying surface of the metal ring, improving the uniformity of spraying on each surface. Subsequently, the rotation of the annular cylinder 24 drives the metal ring gasket to rotate, so that the spraying assembly can evenly spray the spraying surfaces of multiple gaskets, while improving the spraying efficiency and effect of the outer surface of the metal ring gasket, reducing the time cost of production.

[0041] like Figures 1 to 3 As shown, the spray assembly includes: a paint tank 13, a spray pipe 14, a support plate 15, a nozzle 16 and a nozzle 2 17. The two paint tanks 13 are arranged on the top of the box body 10, and the two paint tanks 13 are located on both sides of the rotating rod 20. The paint is contained in the paint tank 13, and multiple spray pipes 14 are correspondingly arranged on the top of the paint tank 13. The support plate 15 is arranged on the top of the box body 10, and the support plate 15 is also located on both sides of the rotating rod 20. A channel is opened inside the support plate 15, and One end of the spray pipe 14 is connected to the channel on the support plate 15, and the nozzle 16 and the nozzle 2 17 are arranged on the opposite side walls of the two support plates 15. The nozzle 16 and the nozzle 2 17 are a group. A plurality of groups of nozzles 16 and nozzles 2 17 are vertically spaced on the support plate 15, and the nozzles 16 and the nozzles 2 17 are arranged in an eight-shaped shape, so that the nozzles 16 and the nozzles 2 17 can spray the upper and lower surfaces and the sides of the metal ring gasket at the same time, thereby improving the spraying efficiency.

[0042] like Figures 1 to 6 As shown, a motor 12 is provided inside the box body 10, and the output end of the motor 12 is connected to the rotating rod 20, and the variable pitch thread 21 is provided on the outer circumferential surface of the rotating rod 20, and the pitch of the variable pitch thread 21 gradually increases from bottom to top. After the annular gasket 23 cooperates with the variable pitch thread 21, the annular gasket 23 can be evenly spaced when moving from bottom to top. Two guide rods 22 are fixedly provided on the top of the box body 10, and a hole 50 is provided on the top of the annular gasket 23, and the guide rod 22 passes through the hole 50. The guide rod 22 can make the annular gasket 23 more stable when moving, and the annular cylinder 24 is rotatably provided on the top of the annular gasket 23.

[0043] When the metal ring gaskets need to be evenly spaced, the motor 12 drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 can drive multiple circular ring gaskets 23 and the circular ring cylinder 24 to move from bottom to top, and multiple circular ring gaskets 23 and the circular ring cylinder 24 are evenly spaced, so that the metal ring gaskets are evenly spaced, so that the metal ring gaskets will not contact with adjacent metal ring gaskets during spraying and rotation, avoiding damage to the sprayed coating, and at the same time ensuring that nozzle 1 16 and nozzle 2 17 evenly spray the upper and lower surfaces and the facade of the metal ring gasket.

[0044] like Figures 3 to 5 As shown, the support group 1 includes: a first fixed box 30, a first support rod 31, a second support rod 32, a bidirectional motor 33, a rotating shaft 34, a first swing rod 35 and a first resistance cap 36. The first fixed box 30 is arranged on the outer circumferential surface of the circular cylinder 24. The two first support rods 31 are respectively hinged on the outer walls on both sides of the first fixed box 30. The end faces of the first support rod 31 and the second support rod 32 are U-shaped end faces. The two second support rods 32 are respectively slidably arranged inside the two first support rods 31, and one end of the second support rod 32 is located inside the first support rod 31. The other end of the second support rod 32 is provided with a first resistance cap 36, and the first resistance cap 36 is used to contact and stop with the inner surface of the metal ring gasket to increase the friction of the support, thereby improving the stability of the support. The bidirectional motor 33 is arranged on the inner bottom wall of the first fixed box 30, and the two output shafts of the bidirectional motor 33 extend out of the outer walls on both sides of the first fixed box 30, and the two first swing rods 35 are respectively arranged on the outer circumferential surfaces of the two output shafts of the bidirectional motor 33, and the other end of the first swing rod 35 is rotatably connected to the second strut 32, and the first swing rod 35 is rotatably connected to one end of the second strut 32 located inside the first strut 31, and the support group 1 on the adjacent annular cylinder 24, and the support group 1 has a first state and a second state. When in the first state, the second strut 32 is retracted inside the first strut 31 and is in a vertical setting. When in the second state, the second strut 32 is unfolded outside the first strut 31 and is in an inclined setting.

[0045] When the metal ring gasket needs to be expanded, the bidirectional motor 33 drives the rotating shafts 34 on both sides to rotate, and the rotation of the rotating shafts 34 drives the first rocker arm 35 to rotate, and the rotation of the first rocker arm 35 drives the first support rod 31 to rotate. The first support rod 31 rotates at the hinge position with the first fixed box 30 as a fulcrum. At the same time, the rotation of the first rocker arm 35 drives the second support rod 32 to slide out of the first support rod 31, so that the first resistance cap 36 contacts the inner facade of the metal ring gasket, thereby forming a support, so as to facilitate the spraying of high-adhesion coating on the metal ring gasket.

[0046] like Figures 3 to 5As shown, support group 2 includes: a second fixed box 40, a third support rod 41, a second resistance cap 42, a second rocker arm 43 and a rotation rod 44. The second fixed box 40 is arranged on the outer circumference of the annular tube 24, and the second fixed box 40 and the annular tube 24 correspond one to one. The two third support rods 41 are respectively hinged on the outer walls on both sides of the second fixed box 40. The second resistance cap 42 is arranged at one end of the third support rod 41. The rotation rod 44 is arranged on the outer walls on both sides of the second fixed box 40 and close to the bottom of the second fixed box 40. The two second rocker arms 43 are respectively arranged on the outer circumferences of the two rotation rods 44. One end of the second rocker arm 43 is slidably hinged inside the third support rod 41. Support group 2 has a first state and a second state. When in the first state, the third support rod 41 is in a vertical setting, and when in the second state, the third support rod 41 is in an inclined setting.

[0047] When the metal ring gasket needs to be expanded, the rotation rod 44 drives the second rocker arm 43 to rotate, and the rotation of the second rocker arm 43 drives the third support rod 41 to rotate. The third support rod 41 and the second fixed box 40 are hinged at a fulcrum for rotation, so that the third support rod 41 is changed from a vertical state to an inclined state, so that the second resistance cap 42 contacts with the inner surface of the metal ring gasket to form a support. The support distances of support group 1 and support group 2 on a circular ring cylinder 24 are inconsistent, so that the supported metal ring gasket is eccentrically supported, so as to improve the efficiency of spraying multiple metal ring gaskets.

[0048] Since a plurality of metal ring gaskets are stacked and arranged in an alternating manner, in order to enable the spraying assembly to coat each metal ring gasket, the metal ring gasket needs to rotate on its own, and thus a driving assembly is provided to drive the annular cylinder 24 to rotate.

[0049] The driving assembly includes: a motor 60, a gear 61 and an annular teeth 62. Multiple motors 60 are respectively arranged on the top of the annular gasket 23. The output shaft end of the motor 60 is provided with a gear 61. The annular teeth 62 are arranged on the inner circumference of the annular cylinder 24, and the gear 61 is meshed with the annular teeth 62.

[0050] When each metal ring gasket is expanded and the spacing is evenly distributed, the motor 60 will drive the gear 61 to rotate. Since the gear 61 is meshed with the annular teeth 62, the rotation of the gear 61 drives the annular cylinder 24 to rotate. The rotation of the annular cylinder 24 drives the support group 1 and the support group 2 to rotate. The rotation of the support group 1 and the support group 2 drives the metal ring gasket to rotate, so that each metal ring gasket can rotate on its own. The metal ring gaskets can rotate on their own and are arranged in a staggered stack so that the spray assembly can efficiently spray high-viscosity coatings on multiple metal ring gaskets, while improving the spraying efficiency of the facade of the metal ring gasket, reducing the time cost of production, and improving production efficiency.

[0052] S1. The metal ring gaskets to be sprayed are stacked and sleeved on the outer peripheral side of the rotating rod 20. The support assembly expands and supports each metal ring gasket so that adjacent metal ring gaskets are stacked alternately. The spray assembly can evenly spray the upper and lower surfaces and the outer facades of multiple metal rings to improve the spraying efficiency and effect.

[0053] S2, then the plurality of circular ring gaskets 23 can be evenly spread and moved from bottom to top, so that each metal ring gasket is evenly spaced and distributed, so that the sprayed paint can be evenly spread to the spraying surface of the metal ring, and at the same time, the metal ring gasket will not contact with the adjacent metal ring gasket during the spraying rotation, avoiding damage to the sprayed coating;

[0054] S3. The driving assembly can make each metal ring gasket rotate, so that the spraying assembly can efficiently spray high-viscosity coatings on multiple metal ring gaskets, while improving the spraying efficiency of the facades of the metal ring gaskets, reducing the time cost of production and improving production efficiency.

The metal ring gaskets to be sprayed are stacked and sleeved on the outer peripheral side of the rotating rod, and the supporting assembly expands and supports each metal ring gasket so that adjacent metal ring gaskets are stacked alternately in sequence, and the spraying assembly can evenly spray the upper and lower surfaces and the outer facades of multiple metal rings; S2. Then, multiple circular ring gaskets can be evenly spread and moved from bottom to top, so that each metal ring gasket is evenly spaced and distributed, so that the sprayed paint can be evenly spread to the spraying surface of the metal ring. At the same time, the metal ring gasket will not contact with the adjacent metal ring gaskets during the spraying rotation, avoiding damage to the sprayed coating; S3. The rotation of the annular cylinder causes each metal ring gasket to rotate, so that the spraying assembly can efficiently spray a high-viscosity coating on multiple metal ring gaskets, while improving the spraying efficiency of the upper and lower surfaces and the outer facades of the metal ring gaskets.
