The original equipment has the working principle that a pair of phi 80 feeding rollers send stator punching sheets into a pair of phi 300 painting rollers for water-soluble paint coating. After the paint is coated, the paint is sent to a conveyor belt to enter an oven for heating and drying, and after drying, the paint enters a cooling section, and after cooling, the paint is discharged to obtain a finished product. The hardness of the paint roller is 45-48 Shore hardness, the hardness is relatively high, the gap between the upper paint roller and the lower paint roller is the thickness of the punching sheet when the water-soluble paint is coated, and the end face (cross section) of the stator punching sheet cannot contact with the paint when the stator punching sheet passes through the upper paint roller and the lower paint roller, so that the end face cannot be coated.
The working principle of the scheme is that a motor 42 drives a painting roller 10 on a lower rubber roller assembly 8 to rotate, and drives the painting roller 10 on a rubber roller assembly 7 to rotate through the same transmission gear 41, so that the rotating speeds of the two are consistent and rotate in opposite directions, and drive a corresponding paint homogenizing roller 39 and a corresponding rubber roller body 38 to rotate respectively; while the paint roller 10 on the lower rubber roller assembly 8 rotates, as part of paint in the lower paint tray 12 is adhered to the surface of the lower rubber roller assembly, the surface of the paint roller 10 with paint on the lower rubber roller assembly 8 uniformly coats the paint on the surface of the corresponding rubber roller body 38 through the paint homogenizing roller 39; similarly, when the painting roller 10 on the painting roller assembly 7 rotates, paint in the painting tray 11 is coated on the surface of the painting roller 10 of the painting roller assembly 7 through the silica gel strip 37 on the paint outlet 14, and the surface of the painting roller 10 with paint on the painting roller assembly 7 is uniformly coated on the surface of the corresponding rubber roller body 38 through the paint homogenizing roller 39; because the hardness of the rubber roll bodies 38 is 28-32, the hardness is lower, the stator punching sheet 4 is conveyed through the conveying table 1, when the rubber roll bodies 38 on the upper rubber roll assembly 7 and the rubber roll bodies 38 on the lower rubber roll assembly 8 rotate in opposite directions when the rubber roll bodies 38 are conveyed between the two rubber roll bodies 38, the rubber roll bodies 38 on the upper rubber roll assembly 7 and the rubber roll assemblies 8 can drive the stator punching sheet 4 to convey forwards, paint is coated on the end face, the top face and the bottom face of the stator punching sheet 4, at the moment, the top face and the bottom face of the stator punching sheet 4 are coated with a layer of thin paint, and then the conveying roller 51 continues to convey the stator punching sheet 4 to keep the level in the conveying process so as to convey the paint between the two painting rollers 10 more accurately; the stator punching sheet 4 is coated with paint again through the paint roller 10, so that the paint on the surface of the stator punching sheet 4 is more uniform and the thickness of the paint is increased to 8-14 microns, and the thickness requirement of the paint can be met more than that of the original equipment; the stator punching sheet 4 after painting is heated and dried by the heating part 53, and then enters the cooling part 54 for cooling after being dried, and finally the finished product is manufactured.
The flow regulating mechanism 15 not only can regulate the range to be coated by paint according to the width of the stator punching sheet 4, but also can regulate the paint quantity of the paint outlet 14; when an operator adds paint into the paint tray 11, the sealing valve 16 is closed in advance, and after a certain amount of paint is added, the sealing valve 16 is opened, so that the operation is favorable for the paint in the paint tray 11 to be simultaneously oozed out of the paint outlet 14 and coated on the surface of the paint roller 10, the paint on the surface of the paint roller 10 on the glue roller assembly 7 is more uniform, and the painting quality is improved.
When the paint flow is required to be regulated by changing the aperture size of the regulating orifice plate 18, an operator only needs to rotate the regulating screw I26 at two sides, so that the regulating screw I26 acts on the regulating orifice plate 18 through the T-shaped block 23; when the T-shaped block 23 presses the regulating orifice plate 18 inwards, the aperture is reduced, the flow is reduced, otherwise, the first regulating screw 26 rotates reversely, and when the T-shaped block 23 is reset gradually under the elastic action, the aperture is increased, and the flow is increased; when the width of the stator punching sheet 4 is smaller than the length of the paint outlet 14, an operator rotates the first adjusting screw 26 which is arranged on the two sides of the paint tray 11 and is not right above the stator punching sheet 4 until the holes on the adjusting orifice plate 18 are almost completely closed, and the paint in the paint tray 11 is not easy to seep out from the holes because the paint has certain viscosity, so that the paint is ensured to be only seeped out from the corresponding position of the stator punching sheet 4 and coated on the top surface of the stator punching sheet 4; in the scheme, the gap between two adjacent T-shaped holes 20 is designed to be small enough, so that when T-shaped blocks 23 in the adjacent T-shaped holes 20 are extruded inwards to reduce the aperture of the adjusting orifice plate 18, the inner diameter of the hole on the adjusting orifice plate 18 between the adjacent two T-shaped holes 20 is correspondingly reduced, and the paint has certain viscosity, so that the amount of exudation of the paint from the adjusting orifice plate 18 is approximately the same as the amount of exudation of other extruded parts on the adjusting orifice plate 18, thereby being beneficial to improving the uniformity of paint coating; because the two sides of the adjusting orifice plate 18 are extruded to form a certain gap with the inner side wall of the paint outlet 14, the design of the elastic steel sheet 24 is beneficial to preventing paint from seeping out from the gap, preventing paint from being wasted and improving the utilization rate and the painting quality of the paint.
When the gap between the upper and lower rubber roller bodies 38 needs to be adjusted, an operator firstly loosens the second adjusting screw 47, the telescopic shaft 49 stretches and drives the rotating plate 43 to rotate, meanwhile, the rubber roller bodies 38 and the paint homogenizing roller 39 which are connected with the adjusting plate 44 are driven to rotate, the gap between the upper and lower rubber roller bodies 38 is adjusted to a proper position, then the second adjusting screw 47 is screwed, so that the horizontal positions of the rubber roller bodies 38 and the paint homogenizing roller 39 of the rubber roller assembly 7 are adjusted, and meanwhile, the paint homogenizing roller 39 can be in mutual pressing contact with the paint roller 10, so that stator punching sheets 4 with different thicknesses and different production standards are applicable, and the application range is wide.
