[0002] The sealant can effectively prevent external impurities such as dust, moisture, and metal particles from entering the bearing interior, thereby ensuring the normal operation of the bearing and extending its service life. In addition, the sealant can also prevent the leakage of lubricant, maintain the lubrication effect of the bearing, and further improve the working efficiency and stability of the bearing.

[0003] Currently, in the production and manufacturing of bearings, in order to maintain the stability of the bearing during use and extend its service life, it is necessary to coat the surface of the outer ring of the bearing with a sealant.

The two ends of the second tension spring 50 are respectively rotatably connected to the second driven wheel 55 and the threaded block 47.

[0023] Working principle: When coating the bearing, the bearing is sleeved on the outer side surfaces of the three support columns 59, and the bearing is pushed until it contacts the limiting piece 60. At this time, the bearing is positioned by the action of the three electric telescopic rods 58. Then, a sealing agent is conveyed into the docking pipe 31. The sealing agent enters the outer pipe 32 through the docking pipe 31. The second sealing pipe 28 is driven to move by the extrusion of the sealing agent, and then drives the sliding pipe 27 to move. The movement of the sliding pipe 27 drives the shunt pipe 26 to drive the two elbow pipes 25 to move, so as to drive the material distribution pipe 10 to move. The movement of the material distribution pipe 10 drives the connecting pipe 11 to drive the fixing sleeve 12 and the fixing pipe 13 to move downward, and further drives the material conveying pipe 17 to drive the connecting cover 7 and the coating sponge 8 to move downward, so that the coating sponge 8 first abuts and fits the surface of the outer ring of the bearing. As the sealing agent continues to be extruded and enters, the second sealing pipe 28 drives the shunt pipe 26, the two elbow pipes 25, the material distribution pipe 10, the connecting pipe 11, the fixing sleeve 12 and the fixing pipe 13 to continue to move downward. Since the coating sponge 8 in contact and extrusion with the outer ring of the bearing will not move further, when the second sealing pipe 28 moves downward into the thickened pipe 33, the fixing sleeve 12 and the fixing pipe 13 also have a relative displacement with the first sealing pipe 14, so that the first sealing pipe 14 enters the fixing sleeve 12.

[0024] Among them, after the second sealing pipe 28 enters the thickened pipe 33, the second sealing pipe 28 is communicated with the inner cavity of the thickened pipe 33 through the second through hole 29. Then, the sealing agent flowing in the docking pipe 31, the outer pipe 32 and the thickened pipe 33 enters the sliding pipe 27 through the second through hole 29, and is then conveyed to the shunt pipe 26 through the sliding pipe 27, and then conveyed to the material distribution pipe 10 through the elbow pipe 25. Then, through the action of the material distribution pipe 10, the sealing agent enters the fixing sleeve 12 through multiple connecting pipes 11.

[0025] Furthermore, after the first sealing tube 14 enters the interior of the fixed sleeve 12, the first sealing tube 14 is connected to the inner cavity of the fixed sleeve 12 through the first through hole 15, so that the sealing agent circulating in the fixed sleeve 12 enters the interior of the delivery pipe 17 through the first through hole 15, and then the sealing agent is transported to the coating sponge 8 through the action of the delivery pipe 17 and the connecting cover 7, and the bearing is coated by the coating sponge 8.

[0026] It is worth noting that, due to the different widths of the bearings, multiple groups of coating sponges 8 are provided in the present solution. Only the coating sponges 8 that are in compression contact with the bearings will cause relative sliding between the fixed sleeve 12 and the fixed tube 13 and the first sealing tube 14, thereby delivering the sealing agent to the coating sponges 8. The coating sponges 8 that are not in compression contact with the bearings do not have the situation of being in compression contact with the bearings, so the sealing agent will not be delivered to the coating sponges 8 that are not in contact with the bearings. Through this design, bearings of different specifications can be coated without replacing the coating head, and the sealing agent will not drip and cause waste. In the process of sliding tube 27 moving downward, protective cover 24 will also be driven downward, so that connecting column 35 drives sliding column 36 to move downward, and then sleeve 37 drives connecting frame 19 to move downward, and through the downward movement of connecting frame 19, rotating shaft 20 drives rotating roller 21 to move downward, and in the process of rotating roller 21 moving downward, it will contact with bearing, and through the action of sliding column 36, sleeve 37 and second spring 38, rotating roller 21 can contact with bearings of different specifications, and after rotating roller 21 contacts with bearing, motor 40 is started, and through the action of motor 40, first driving wheel 41 is rotated, so that first belt 42 is rotated, and then two groups of first driven wheels 43 connected thereto are rotated, and then two groups of rotating shafts 20 drive rotating roller 21 to rotate, and the bearing is rotated through the rotation of rotating roller 21, and then the outer ring of the bearing is coated; During the startup of the motor 40 to drive the first driving wheel 41 to rotate, the first driving wheel 41 will drive the transmission shaft 52 to rotate, thus driving the second driving wheel 53 to rotate, and then driving the second driven wheel 55 to rotate through the second belt 54, thus driving the threaded column 48 to rotate, and further causing the threaded block 47 to drive the extrusion sleeve 46 to move, so that the extrusion sleeve 46 is extruded onto the support table 1. Through the reaction force, the protective cover 24 can be extruded to ensure the stability of the protective cover 24. Therefore, the coating sponge 8 and the rotating roller 21 can always maintain the state of the coating work. It should be noted that the motor 40 is always in the startup state during the coating work, that is, the threaded column 48 is always rotating. Therefore, after the extrusion sleeve 46 is in extrusion contact with the support table 1, the threaded block 47 will disengage from the threaded column 48 and be located on the outer side of the connecting shaft 49, and the threaded block 47 is always closely attached to the threaded column 48 through the action of the second tension spring 50. Therefore, when the threaded column 48 is always rotating, the threaded block 47 will not move further. However, when the threaded column 48 rotates in reverse, the threaded block 47 can move reversely and reset through the action of the second tension spring 50; After the coating work is completed, the sealing agent is stopped from being conveyed. Through the action of the first tension spring 34 and the first spring 16, the sliding tube 27 and the coating sponge 8 are all reset to the initial state, which is convenient for coating the next group of bearings.
