Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor end cover production equipment, and particularly relates to a Teflon spraying device for motor end cover production and a spraying method thereof. BACKGROUND

[0002] During the production of a motor end cover, the surface of the motor end cover needs to be sprayed with Teflon. In order to improve the spraying efficiency, workers usually replace multiple motor end covers without interrupting the spraying. During the spraying process, the workers need to control the spraying direction of the spraying pipe to be always perpendicular to the surface of the motor end cover, so that the spraying is more uniform, thereby achieving the purpose of effective spraying.

[0003] Since the edges of the motor end cover are not easy to spray during the spraying, the current spraying device is not convenient for edge sealing spraying of the motor end cover, thereby leading to incomplete spraying. In addition, the Teflon is prone to precipitation after being placed, and the current spraying device is not convenient for stirring the Teflon during the spraying, thereby leading to uneven composition of the Teflon, and thus leading to poor spraying effect.

[0013] Further, the heating ring is fixedly connected to the bottom of the limiting plate.

[0014] A spraying method of a Teflon spraying device for motor end cover production, comprising the following steps:

[0015] Step one: when the motor end cover needs to be placed and sprayed, the workers place a plurality of the motor end cover in turn through the protrusions of the limiting plate on each limiting plate respectively, while connecting the Teflon through the hose on the spraying pipe, and connecting the Teflon through the pipeline on the feed inlet of the liquid valve, then the workers start the servo motor and the drive motor, the drive motor drives one of the motor end cover to rotate, while the servo motor drives the extrusion ring to rotate, the extrusion ring makes the roller drive the spraying pipe to move while slowly rotating, the Teflon uniformly sprays the surface of the motor end cover, then the servo motor drives the support plate to rotate through the overrunning clutch to make the motor end cover quickly change, thereby completing the spraying;

[0016] Step two: when spraying, the moving rod moves downward so that the blocking block no longer blocks the feed inlet of the liquid valve, the Teflon enters the edge sealing pipe through the liquid valve and the connecting pipe, then the Teflon sprays to the bottom edge of the high-speed rotating motor end cover through the edge sealing pipe, thereby completing the edge sealing, the Teflon entering the spraying pipe will make the thousand-leaf fan rotate, the thousand-leaf fan rotates to reciprocate along the bidirectional screw thread shaft through the screw block, thereby stirring the passing Teflon;

[0017] Step three: when the spraying is completed, the workers turn off the drive motor and the servo motor, while taking off the Teflon from the spraying pipe through the hose, and taking off the Teflon from the feed inlet of the liquid valve through the pipeline, then the workers take off the sprayed motor end cover.

[0018] The application has the following advantages: 1, the drive motor drives one of the motor end cover to rotate at high speed, while the servo motor drives the transmission shaft and the extrusion ring to rotate together, the extrusion ring rotates to extrude the moving rod to move downward, the moving rod moves through the sliding frame to make the rotating frame, the roller and the spraying pipe move downward together, the roller moves downward while moving along the arc-shaped structure of the limiting strip to make the spraying pipe move transversely, while the roller also slowly rotates the spraying pipe by pulling the spraying pipe through the limiting strip, the Teflon always maintains a perpendicular angle with the surface of the motor end cover for spraying through the movement and rotation of the spraying pipe, thereby making the spraying more uniform, then the servo motor drives the support plate to rotate through the overrunning clutch, the rotation of the support plate makes the motor end cover rotate by a certain angle, thereby quickly changing the motor end cover, thereby improving the spraying efficiency.

[0019] When the moving rod moves downward to drive the sliding shaft to move downward, the blocking block moves downward and no longer covers the feed port of the liquid valve, and the feed port of the liquid valve communicates with the discharge port of the liquid valve. Teflon is pumped into the liquid valve through the feed port of the liquid valve, then enters the edge sealing pipe from the liquid valve through the connecting pipe, and then is sprayed to the bottom edge of the rotating motor end cover through the edge sealing pipe, thereby sealing the edge of the motor end cover, and the spraying of the motor end cover is more comprehensive, thereby enhancing the spraying effect.

[0020] The flow of Teflon drives the thousand-leaf fan to rotate, the thousand-leaf fan rotates to drive the threaded block to rotate, the threaded block rotates to drive the rotating thousand-leaf fan to move to one side through the bidirectional threaded shaft, and then the threaded block continues to rotate to drive the thousand-leaf fan to move reversely to reset through the bidirectional threaded shaft. Repeat this, the threaded block rotates to drive the rotating thousand-leaf fan to reciprocate along the bidirectional threaded shaft through the bidirectional threaded shaft, thereby agitating the passing Teflon, thereby making the components in the Teflon more uniform, thereby improving the quality of the Teflon, thereby further enhancing the spraying effect.

[0038] Firstly, the staff will need to spray the motor end cover 5 through the protrusions of the limiting plate 4 on the limiting plate 4 in turn, while connecting the Teflon through the hose on the spray pipe 66, then the staff starts the servo motor 2 and the drive motor 37, the output shaft of the drive motor 37 rotates at high speed and drives one of the driven gears 35 to rotate at high speed through the transmission gear 38, and then drives one of the rotating shafts 34, one of the limiting plates 4 and one of the motor end covers 5 to rotate at high speed, while the output shaft of the servo motor 2 rotates to drive the transmission shaft 31 and the extrusion ring 61 to rotate together, the rotation of the extrusion ring 61 will extrude the moving rod 62 to move downward, the movement of the moving rod 62 will drive the rotating frame 64 and the spray pipe 66 to move downward through the sliding frame 63, the spray pipe 66 will spray Teflon on the top of the rotating motor end cover 5, the rotating frame 64 will drive the limiting block 68 and the roller 69 to move downward while moving downward, the roller 69 will drive the rotating frame 64 and the spray pipe 66 to move transversely to the direction close to the transmission shaft 31 while moving downward along the arc-shaped structure of the limiting strip 67, and the roller 69 will also pull the rotating frame 64 and the spray pipe 66 to rotate slowly, the torsional spring 65 is twisted, the Teflon will always maintain a perpendicular angle with the surface of the motor end cover 5 through the movement and rotation of the spray pipe 66 for spraying, thereby making the spraying more uniform, then the reverse rotation of the output shaft of the servo motor 2 will drive the support plate 33 to rotate through the overrunning clutch 32, the rotation of the support plate 33 will drive the rotating shaft 34, the driven gear 35, the limiting plate 4 and the motor end cover 5 to rotate by a certain angle, the rotation of the driven gear 35 will disengage from the transmission gear 38, then another driven gear 35 will engage with the rotating transmission gear 38, the transmission gear 38 will make another motor end cover 5 rotate at high speed through another driven gear 35, thereby quickly changing the motor end cover 5, thereby improving the spraying efficiency, the reverse rotation of the transmission shaft 31 will drive the extrusion ring 61 to rotate reversely, the reverse rotation of the extrusion ring 61 will extrude the moving rod 62 to reset upward, the reset of the moving rod 62 will make the rotating frame 64, the spray pipe 66 and the roller 69 reset upward together, the upward reset of the roller 69 will make the rotating frame 64 and the spray pipe 66 reverse rotate for reset together through the cooperation of the arc-shaped structure of the limiting strip 67 and the reset of the torsional spring 65, then the spray pipe 66 will spray Teflon on the surface of another motor end cover 5, after the spraying is completed, the staff turns off the drive motor 37 and the servo motor 2, and removes the Teflon from the spray pipe 66 through the hose, then the staff can take down the sprayed motor end cover 5.

[0039] Example 2: on the basis of example 1, as Figures 2-8As shown, the edge sealing mechanism is arranged on the outer frame 1, and is used for edge sealing of the edge of the motor end cover 5. The edge sealing mechanism comprises a liquid valve 71 which is connected to the inner wall of the outer frame 1 by bolts. The liquid valve 71 is provided with an inlet on one side of the top, and is provided with an outlet on one side of the bottom. A sliding shaft 72 is welded on the moving rod 62, and is slidably connected to the liquid valve 71. A blocking block 73 is slidably connected to the sliding shaft 72, and is located in the liquid valve 71. The blocking block 73 is in contact with the inner wall of the liquid valve 71, and blocks the inlet of the liquid valve 71. The blocking block 73 is used for blocking and opening the flow of Teflon. The outlet of the liquid valve 71 is fixedly connected with a connecting pipe 74. The bottom of the connecting pipe 74 is fixedly connected with an edge sealing pipe 75. The edge sealing pipe 75 is in communication with the liquid valve 71 through the connecting pipe 74.

[0040] The spray head of the edge sealing pipe 75 is arranged in an arc shape, and is used for spraying Teflon on the bottom edge of the motor end cover 5.

[0041] Before the staff starts the servo motor 2 and the driving motor 37, the staff first connects the Teflon to the inlet of the liquid valve 71 through the pipeline. When the moving rod 62 moves downward, the moving rod 62 drives the sliding shaft 72 to move downward, so that the blocking block 73 moves downward and no longer blocks the inlet of the liquid valve 71. At the same time, the inlet of the liquid valve 71 is in communication with the outlet of the liquid valve 71. The Teflon is pumped into the liquid valve 71 through the inlet of the liquid valve 71. Then the Teflon enters the edge sealing pipe 75 from the liquid valve 71 through the connecting pipe 74. Then the Teflon is sprayed to the bottom edge of the high-speed rotating motor end cover 5 through the edge sealing pipe 75, so as to seal the edge of the motor end cover 5, and make the spraying of the motor end cover 5 more comprehensive, thereby enhancing the spraying effect. When the moving rod 62 resets upward, the moving rod 62 drives the sliding shaft 72 to reset upward, so that the blocking block 73 resets upward and blocks the inlet of the liquid valve 71 again. After spraying, the staff can remove the Teflon from the inlet of the liquid valve 71 through the pipeline.

[0042] In example 2, the edge sealing mechanism is arranged on the outer frame 1, and is used for edge sealing of the edge of the motor end cover 5. The edge sealing mechanism comprises a liquid valve 71 which is connected to the inner wall of the outer frame 1 by bolts. The liquid valve 71 is provided with an inlet on one side of the top, and is provided with an outlet on one side of the bottom. A sliding shaft 72 is welded on the moving rod 62, and is slidably connected to the liquid valve 71. A blocking block 73 is slidably connected to the sliding shaft 72, and is located in the liquid valve 71. The blocking block 73 is in contact with the inner wall of the liquid valve 71, and blocks the inlet of the liquid valve 71. The blocking block 73 is used for blocking and opening the flow of Teflon. The outlet of the liquid valve 71 is fixedly connected with a connecting pipe 74. The bottom of the connecting pipe 74 is fixedly connected with an edge sealing pipe 75. The edge sealing pipe 75 is in communication with the liquid valve 71 through the connecting pipe 74. Figure 9As shown, the agitating mechanism is arranged on the spraying pipe 66, and is used for agitating the sprayed Teflon. The agitating mechanism comprises a limiting frame 81 welded on the inner wall of the spraying pipe 66, a bidirectional threaded shaft 82 welded on the limiting frame 81, a threaded block 83 threadedly connected on the bidirectional threaded shaft 82, and a thousand-leaf fan 84 boltedly connected on the threaded block 83. The thousand-leaf fan 84 is used for agitating the Teflon.

[0043] When the Teflon is sprayed through the spraying pipe 66, the flowing Teflon drives the thousand-leaf fan 84 to rotate, the rotating thousand-leaf fan 84 drives the threaded block 83 to rotate, the rotating threaded block 83 drives the rotating thousand-leaf fan 84 to move to one side through the bidirectional threaded shaft 82, and then the continuous rotation of the threaded block 83 drives the thousand-leaf fan 84 to move reversely to reset through the bidirectional threaded shaft 82. Repeating the above process, the rotation of the threaded block 83 drives the rotating thousand-leaf fan 84 to move back and forth along the bidirectional threaded shaft 82 through the bidirectional threaded shaft 82, thereby agitating the passing Teflon, making the components in the Teflon more uniform, improving the quality of the Teflon, and further enhancing the spraying effect.

[0044] In the embodiment 3, the heating ring 9 is further arranged. Figures 3-10 As shown, the heating ring 9 is arranged on the bottom of the limiting plate 4, and is used for drying the motor end cover 5.

[0045] Before the staff places the motor end cover 5, the staff first powers on the heating ring 9. When the staff places the motor end cover 5, the powered heating ring 9 releases heat. Before spraying, the heating ring 9 evaporates the moisture on the motor end cover 5 to keep the motor end cover 5 dry. After spraying, the heating ring 9 quickly dries the sprayed Teflon on the motor end cover 5. In this way, the Teflon is more easily attached to the surface of the motor end cover 5 during spraying, and the Teflon is quickly dried after spraying, thereby improving the spraying efficiency of the Teflon. After the spraying is completed, the staff can power off the heating ring 9.

[0046] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
