Description

Technical Field

[0001] This utility model relates to the technical field of steel strip coating equipment, and in particular to an electrical steel strip coating equipment. Background Technology

[0002] Steel strip, also known as strip steel, is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Electrical steel strip is a commonly used production steel strip. In some processing workshops, different types of mechanical products need to be processed and produced in batches. Therefore, it is necessary to coat the electrical steel strip with appropriate coatings according to process requirements.

[0003] Patent CN205199845U discloses a magnesium oxide coating equipment, including a frame, two coating rollers, two sprayers, and two flow control valves. The two coating rollers are mounted on the frame and arranged vertically. The two sprayers are respectively located on the same side of the two coating rollers and arranged vertically. The two flow control valves are respectively connected to the pipes of the two spray heads.

[0004] During operation, the aforementioned equipment requires a traction device to pull the movable end of the steel strip so that it can pass horizontally between two coating rollers. However, the steel strip is quite long and will sag under its own weight. This results in an excessive angular deviation between the steel strip and the two coating rollers when the steel strip enters the space between them. Consequently, the coating thickness on the lower surface of the steel strip differs significantly from that on the upper surface, leading to poor coating quality on the steel strip surface. Utility Model Content

[0005] In view of the above problems, this utility model provides a coating equipment for electrical steel strips.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A coating equipment for electrical steel strip is provided, including a base and a coating machine body mounted on the base. Two coating rollers are spaced apart along the height of the coating machine body, and a channel for the steel strip to pass through is left between the two coating rollers. Both coating rollers are rotatably mounted on the coating machine body. The coating machine body is provided with a first driving member for driving the two coating rollers to rotate. A steel strip lifting mechanism is provided on the outer side of the coating machine body at the feed end of the channel for lifting the steel strip and tilting it. The plane where the center lines of the two coating rollers are located is perpendicular to the steel strip.

[0008] Furthermore, the coating machine body is rotatably mounted on the base, the base is provided with a second driving component for driving the coating machine body to rotate, and the base is also provided with a support component for assisting in supporting the coating machine body.

[0009] Furthermore, the support accessories include multiple support columns, one end of which is vertically threaded to the base, and the other end of which is movably abutting against the bottom of the coating machine body.

[0010] Furthermore, a handle is fixed to the outer wall of the support column.

[0011] Furthermore, the steel strip lifting mechanism includes a fixed roller and a lifting roller. A mounting frame is provided on the outside of the coating machine body. The fixed roller is rotatably mounted on the mounting frame. A support is vertically slidably mounted on the mounting frame on the side of the fixed roller close to the coating machine body. The lifting roller is rotatably mounted on the support. A space is left between the fixed roller and the lifting roller for the steel strip to wind and pass through. A third driving component is provided on the mounting frame for driving the support to move.

[0012] Furthermore, it also includes a correction mechanism for limiting the deviation of the steel strip relative to the coating roller. The correction mechanism includes two limiting plates, which are slidably disposed on both sides of the coating machine body in a direction parallel to the coating roller and disposed at the feed end of the channel. The side of the two limiting plates that are close to each other has a groove for the steel strip to pass through. The coating machine body is provided with a fourth driving member for driving the two limiting plates to move to adjust the distance between the two limiting plates.

[0013] The beneficial effects of this utility model are as follows: the steel strip can be lifted and tilted by the steel strip lifting mechanism to reduce the sag of the steel strip, thereby reducing the angular deviation between the steel strip and the two coating rollers, and thus reducing the coating thickness deviation between the upper and lower surfaces of the steel strip, thereby improving the coating quality of the steel strip.

[0018] 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.

[0019] This application discloses an electrical steel strip coating device, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a base 1 and a coating machine body 2 mounted on the base 1. Two coating rollers 3 are spaced apart along the height of the coating machine body 2, with a channel between the two rollers 3 for the steel strip to pass through. Both coating rollers 3 are rotatably mounted on the coating machine body 2, and a first drive unit 4 is installed on the coating machine body 2 to drive the two coating rollers 3 to rotate. A steel strip lifting mechanism 5 is installed on the outer side of the coating machine body 2 at the feed end of the channel to lift and tilt the steel strip. The plane containing the centerlines of the two coating rollers 3 is perpendicular to the steel strip.

[0020] In this embodiment, the first driving component 4 includes two first driving motors, which are mounted on the coating machine body 2, and the output shafts of the two first driving motors are respectively connected to two coating rollers 3. The steel strip lifting mechanism 5 can lift and tilt the steel strip to reduce its sag, thereby reducing the angular deviation between the steel strip and the two coating rollers 3. This reduces the coating thickness deviation between the upper and lower surfaces of the steel strip, thus improving the coating quality of the steel strip.

[0021] Furthermore, the coating machine body 2 is rotatably mounted on the base 1, and a second driving component 6 for driving the coating machine body 2 to rotate is installed on the base 1. A support component 7 for assisting in supporting the coating machine body 2 is also installed on the base 1.

[0022] In this embodiment, the second driving component 6 includes two driving cylinders, which are rotatably mounted on the base 1, and their piston rods are rotatably connected to the bottom of the coating machine body 2. Extending the piston rods can support the coating machine body 2 and cause it to rotate and tilt, thereby ensuring that the plane containing the centerlines of the two coating rollers 3 is perpendicular to the steel strip. The supporting auxiliary component 7 can cooperate with the two driving cylinders to jointly support the coating machine body 2.

[0023] Specifically, the support component 7 includes multiple support columns 71, one end of which is vertically threaded onto the base 1, and the other end of which is movably abutting against the bottom of the coating machine body 2.

[0024] After the drive cylinder moves the piston rod and causes the coating machine body 2 to rotate and tilt, the operator can manually rotate the support column 71 so that it can rise and contact the bottom of the coating machine body 2. During the coating operation, the pressure on the drive cylinder can be distributed through multiple support columns 71.

[0025] To facilitate the rotation of the support column 71 by the staff, a handle 8 is welded and fixed on the outer wall of the support column 71.

[0026] Specifically, the steel strip lifting mechanism 5 includes a fixed roller 51 and a lifting roller 52. A mounting frame 9 is provided on the outside of the coating machine body 2. The fixed roller 51 is rotatably mounted on the mounting frame 9. A support 91 is vertically slidably mounted on the mounting frame 9 on the side of the fixed roller 51 closest to the coating machine body 2. The lifting roller 52 is rotatably mounted on the support 91. A space is left between the fixed roller 51 and the lifting roller 52 for the steel strip to wind and pass through. A third driving member 10 is provided on the mounting frame 9 to drive the support 91 to move.

[0027] In this embodiment, the third driving component 10 includes a first electric push rod, which is mounted on the mounting bracket 9. The movable end of the first electric push rod faces vertically upward and is connected to the bracket 91. By driving the bracket 91 to move vertically through the first electric push rod, the tilt angle of the steel strip can be adjusted.

[0028] Furthermore, the system also includes a correction mechanism 20 for limiting the deviation of the steel strip relative to the coating roller 3. The correction mechanism 20 includes two limiting plates 201, which are slidably disposed on both sides of the coating machine body 2 in a direction parallel to the coating roller 3 and located at the feed end of the channel. The sides of the two limiting plates 201 that are close to each other have grooves 2011 for the steel strip to pass through. A fourth driving member 30 is installed on the coating machine body 2 to drive the two limiting plates 201 to move and adjust the distance between the two limiting plates 201.

[0029] In this embodiment, the fourth driving component 30 includes two second electric push rods, which are horizontally mounted on both sides of the coating machine body 2, and the movable ends of the two second electric push rods are connected to corresponding limiting plates 201. By driving the two limiting plates 201 to move, the distance between the two limiting plates 201 can be adjusted to ensure that both sides of the steel strip can move through the grooves 2011 of the two limiting plates 201. The two limiting plates 201 prevent one side of the steel strip from shifting out of the two coating rollers 3 during the coating process, thus avoiding incomplete coating and improving the coating quality of the steel strip.

[0030] The implementation principle of the electrical steel strip coating equipment in this application embodiment is as follows: the steel strip can be lifted and tilted by the steel strip lifting mechanism 5 to reduce the sag of the steel strip, thereby reducing the angular deviation between the steel strip and the two coating rollers 3, so that the coating thickness deviation between the upper and lower surfaces of the steel strip is also reduced, thus improving the coating quality of the steel strip.
