[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] Embodiment 1 of this application discloses an electrical steel strip coating machine, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mounting frame 1, on which a first coating roller 2 and a second coating roller 3 are spaced apart. The first coating roller 2 and the second coating roller 3 are rotatably mounted on the mounting frame 1, with the first coating roller 2 positioned above the second coating roller 3. A channel is provided between the first coating roller 2 and the second coating roller 3 for the passage of a power supply steel belt. The mounting frame 1 is equipped with a first coating mechanism for coating the outer wall of the first coating roller 2 and a second coating mechanism for coating the outer wall of the second coating roller 3. The mounting frame 1 is also equipped with a first drive member 6 for driving the first coating roller 2 to rotate and a second drive member 7 for driving the second coating roller 3 to rotate.

[0023] In this embodiment, both the first driving member 6 and the second driving member 7 are driving motors. The driving motors are mounted on the mounting frame 1, and the output shaft of the driving motors is connected to the corresponding first coating roller 2 / second coating roller 3.

[0024] The first coating mechanism and the second coating mechanism can respectively apply coating to the outer walls of the first coating roller 2 and the second coating roller 3. During the passage of the electrical steel strip through the channel, the outer walls of the first coating roller 2 and the second coating roller 3 are pressed into contact with both sides of the electrical steel strip. The first coating roller 2 and the second coating roller 3 rotate synchronously in opposite directions, thus applying the coating to both sides of the electrical steel strip. This improves the convenience of coating operations for workers.

[0025] Specifically, the first coating mechanism includes a first coating pipe 4, which is mounted on the mounting frame 1 and located on one side of the first coating roller 2. The first coating pipe 4 is parallel to the first coating roller 2, and multiple nozzles 41 are spaced apart on the outer wall of the first coating pipe 4. One end of the first coating pipe 4 is connected to a supply mechanism (not shown in the figure) for supplying coating. The second coating mechanism includes a coating tank 5 containing coating, which is mounted on the mounting frame 1 and located below the second coating roller 3. The lowest point of the second coating roller 3 is submerged below the surface of the coating liquid. The supply mechanism supplies material to the coating tank 5 through the second coating pipe 51. The outer wall of the second coating pipe 51 is provided with an injection head 511, which faces downward and is located above the coating tank 5.

[0026] In this embodiment, paint can be sprayed onto the outer wall of the first coating roller 2 through multiple nozzles 41, and paint dripping from the first coating roller 2 can also fall into the paint tank 5 below. Since the lowest point of the second coating roller 3 is immersed below the liquid surface of the paint, when the second coating roller 3 rotates, its outer wall can be coated with paint.

[0027] During the spraying of paint by nozzle 41, the liquid paint impacts the outer wall of the first coating roller 2, and some paint easily splashes out from above the first coating roller 2 and drips onto the already coated parts of the electrical steel strip. To solve this problem, a first baffle 8 is provided on the mounting frame 1 above the first coating roller 2 to block the paint splashing out from above the first coating roller 2.

[0028] In this embodiment of the application, the paint splashed onto the first baffle 8 can drip into the first coating roller 2 and the paint tank 5 below it.

[0029] Specifically, the first coating roller 2 includes a first roller 21 and a first coating layer 22 disposed on the outer wall of the first roller 21, and the second coating roller 3 includes a second roller 31 and a second coating layer 32 disposed on the outer wall of the second roller 31. The first roller 21 and the second roller 31 are respectively rotatably mounted on the mounting frame 1, and the first coating layer 22 and the second coating layer 32 are respectively pressed into contact with both sides of the electrical steel strip.

[0030] The coating material can be adsorbed by the first coating layer 22 and the second coating layer 32, and the coating material is adhered to both sides of the electrical steel strip during the extrusion process.

[0031] Specifically, both the first coating layer 22 and the second coating layer 32 are wool felt.

[0032] The implementation principle of the electrical steel strip coating machine in Embodiment 1 of this application is as follows: The first coating mechanism and the second coating mechanism can respectively coat the outer walls of the first coating roller 2 and the second coating roller 3 with coating. During the process of the electrical steel strip passing through the channel, the outer walls of the first coating roller 2 and the second coating roller 3 are pressed and contacted with both sides of the electrical steel strip. The first coating roller 2 and the second coating roller 3 rotate synchronously in opposite directions, thus coating both sides of the electrical steel strip with coating. This improves the convenience of coating operations for workers.

[0033] Example 2

[0034] The difference between Embodiment 2 and Embodiment 1 is that the paint tank 5 is vertically slidably mounted on the mounting frame 1, and the mounting frame 1 is provided with a third driving member 9 for driving the paint tank 5 to move. The paint tank 5 has clearance openings 52 on both sides to avoid the rotating shaft of the second coating roller 3. A second baffle 10 is vertically slidably mounted at the clearance opening 52, and the paint tank 5 is provided with an elastic member for driving the second baffle 10 to move to open / close the clearance opening 52.

[0035] In this embodiment, the third driving component 9 is an electric push rod, which is mounted on the mounting bracket 1. The movable end of the electric push rod faces vertically upward and is connected to the bottom of the paint tank 5.

[0036] When the coating operation enters the final stage, the second coating pipe 51 stops injecting coating into the coating tank 5. The coating tank 5 is moved upward by an electric push rod so that the remaining material in the coating tank 5 can be used up as much as possible, which has the effect of saving resources.

[0037] The second baffle 10 can prevent the paint in the paint tank 5 from flowing out of the clearance opening 52. During the upward movement of the paint tank 5, the rotating shaft of the second coating roller 3 abuts against the top of the second baffle 10 and overcomes the elastic force of the elastic element, so that the second baffle 10 can move downward.

[0038] Reference Figure 4 The elastic element includes a spring 20. The top of the paint tank 5 has a vertical groove 53 at the notch for the second baffle 10 to slide. The spring 20 is vertically installed in the groove 53, and the two ends of the spring 20 are welded and fixed to the second baffle 10 and the bottom wall of the groove 53, respectively.

[0039] To improve the utilization rate of paint in paint tank 5, the inner bottom wall of paint tank 5 is designed to be curved.
