Description

Technical Field

[0001] This invention relates to the field of silicon steel plate coating technology, and in particular to a double-sided coating device for silicon steel plates. Background Technology

[0002] Silicon steel is a silicon alloy steel containing 1.0% to 4.5% silicon and less than 0.08% carbon. It possesses characteristics such as high magnetic permeability, low coercivity, and high resistivity, resulting in low hysteresis and eddy current losses. During nitriding heat treatment, if oil contamination is present on the steel plate's surface, it may lead to uneven nitriding layer thickness or soft spots on the nitrided surface. To reduce the impact of oil contamination on the heat treatment process, the oil contamination on the steel plate surface needs to be treated.

[0003] In the prior art, patent document CN116281167B discloses a steel plate surface treatment production line that facilitates feeding. It includes two inclined feeding devices arranged vertically, a pretreatment device, and a wiping device mounted above the feeding devices. The pretreatment device coats the surface of the steel plate with foam, and the wiping device wipes away the foam coating. The feeding end of the lower feeding device corresponds to the unloading end of the upper feeding device. It also includes a flipping device for turning the steel plate over. The steel plate is conveyed using the adjustable-inclination feeding device, allowing it to slide down due to its own inertia, with the sliding speed changing with the inclination angle of the feeding device. The flipping device causes the steel plate to flip as it moves from the unloading end of the upper feeding device to the feeding end of the lower feeding device, thus cleaning the reverse side of the steel plate during subsequent sliding, achieving double-sided cleaning of the steel plate in a single feeding operation.

[0004] The existing technology has the following problems: In order to reduce the impact of oil on the heat treatment process, silicon steel plates are first cleaned on both sides and coated on both sides. However, the existing silicon steel plates are relatively heavy plates. When coating small pieces of silicon steel plates on both sides, the silicon steel plates need to be stacked on the surface of a specific support frame. The coating is then carried out by workers or machinery, and then workers have to move them down. However, this method can only hold one silicon steel plate per support frame, and only one silicon steel plate can be coated at a time, which is inefficient. In addition, it is also difficult to disassemble the heavy silicon steel plates on the surface of the support frame. There is a risk that the heavy silicon steel plates may fall and injure workers. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the fact that in the prior art, one support frame can only fix one silicon steel plate. In order to prevent the silicon steel plate from falling, the support frame also needs to fix the four corners of the silicon steel plate. Only one silicon steel plate can be coated at a time, which is inefficient. Moreover, when disassembling the silicon steel plate, in order to prevent the silicon steel plate from tipping over, one employee needs to support and limit the small silicon steel plate, and another person needs to disassemble and fix the four corners of the silicon steel plate. Then, the employee supporting the silicon steel plate will carry the silicon steel plate down. The whole process is quite troublesome.

[0006] To solve the above-mentioned technical problems, the present invention provides a double-sided coating device for silicon steel plates, comprising:

[0007] A support frame is installed at the outer edge of the closed casing;

[0008] A movable frame that is slidably sleeved on the inner wall of the support frame;

[0009] The silicon steel plate is attached to the inner wall of the top of the mobile frame. Due to its length and inclined surface, the silicon steel plate will be dragged and swayed back. The side of the silicon steel plate is fixed by snap-fit ​​buckles to prevent the silicon steel plate from collapsing due to shaking when it is upright, thus preventing impact injury to employees.

[0010] A silicon steel plate anti-sway peeling unit is provided on the top outer surface of the mobile frame one. The silicon steel plate anti-sway peeling unit includes a silicon steel plate limiting platform. A steel plate snap-fit ​​groove is opened on one side edge of the inner side of the silicon steel plate limiting platform. An overlapping strip is fixedly connected to the other side wall of the silicon steel plate limiting platform at the top edge. A limiting rod two is fixedly installed on the outer side wall of the silicon steel plate limiting platform at one side edge of the steel plate snap-fit ​​groove. A swing telescopic arm is movably sleeved on the outer surface of the limiting rod two. After it is fixed, the swing telescopic arm is pulled and swung with the connection between the limiting rod two and the swing telescopic arm as the support point. The bottom corner of the silicon steel plate is pulled out from the inside of the steel plate snap-fit ​​groove and overlapped on the top surface of the silicon steel plate limiting platform. One end of the swing telescopic arm is fixedly connected to... A snap-fit ​​latch is movably fitted onto the outer surface of the top of the silicon steel plate. By twisting the swing telescopic arm, the snap-fit ​​latch at one end is engaged with the top corner surface of the silicon steel plate located on one side of the steel plate snap-fit ​​groove. A drain mesh plate is detachably installed on the inner wall of the bottom of the silicon steel plate limiting platform and at one edge position, which is movably overlapped on the outer surface of the top of the overlap strip. A limiting hollow strip is fixedly connected to the top surface of the drain mesh plate and is movably attached to the two sides of the silicon steel plate. Under subsequent pulling, with the joint between the silicon steel plate and the silicon steel plate limiting platform as the support point, the silicon steel plate is swung under the drag of the swing telescopic arm, causing the silicon steel plate to fall off the inner wall of the limiting hollow strip. A relatively stable triangular shape is formed by the swing telescopic arm, the bottom corner of the silicon steel plate, and the silicon steel plate limiting platform.

[0011] In one embodiment of the present invention, a liquid guiding groove is provided on the bottom inner wall of the silicon steel plate limiting platform, and a drain outlet is provided on the inner wall of the silicon steel plate limiting platform at the lowest point of the liquid guiding groove. The drain outlet is located at the lowest vertical point of the overlapping strip. The top surface of the liquid leakage mesh plate is fixedly connected to the two sides of the silicon steel plate. When the silicon steel plate is transported and placed on the top surface of the liquid leakage mesh plate, the bottom corner of the silicon steel plate is preferably snapped onto the inner surface of the steel plate snap-fit ​​groove.

[0012] In one embodiment of the present invention, a limiting collar is fixedly connected to the top surface of the mobile frame and at the two side edges, and a limiting rod is movably sleeved on the inner side wall of the limiting collar. Multiple sets of V-shaped brackets are fixedly connected to the two end surfaces of the limiting rod.

[0013] In one embodiment of the present invention, an overlapping support plate is fixedly connected to the top surface of the V-shaped bracket, and symmetrically installed movable rollers are provided on both sides of the overlapping support plate.

[0014] In one embodiment of the present invention, the silicon steel plate limiting platform is positioned on the top surface of the overlapping support plate and located in the middle position. The top surface of the overlapping support plate is fixedly connected with elastic wires located on both sides of the silicon steel plate limiting platform, and a support column is fixedly connected to the top of the elastic wire.

[0015] In one embodiment of the present invention, an overlapping top plate is fixedly connected to the top of the support column, and a mobile frame two is fixedly installed on the top surface of the overlapping top plate at the middle position.

[0016] In one embodiment of the present invention, an upward moving track is fixedly connected to the top two sides of the support frame and is movably sleeved on the outer surface of the second mobile frame. A downward moving track is provided on the bottom surface of the upward moving track and perpendicular to the bottom. One end of the downward moving track is fixedly connected to the bottom two sides of the closed shell.

[0017] In one embodiment of the present invention, an opening is provided at the position where the downward moving track connects with the bottom surface of the closed sleeve, and an upward ramp is fixedly connected to the inner surface of the downward moving track at the position where it connects with the closed sleeve.

[0018] In one embodiment of the present invention, a return flow mesh and a jet flow mesh are respectively provided on the inner walls of both sides of the closed casing. An upward inclined groove is provided on the inner wall of the closed casing at the bottom edge of the jet flow mesh. A flow ramp is fixedly installed on the inner walls of both sides of the closed casing. A downward sliding ramp is provided on the outer surfaces of both sides of the closed casing at the edges of the downward track.

[0019] In one embodiment of the present invention, a paint sprayer is provided on the outer surface of the closed casing and at the outer edge of the return mesh port. A liquid guide tube is fixedly connected to the output end of the paint sprayer and is movably connected to the top outer surface of the closed casing. The other end of the liquid guide tube is fixedly connected to the outer surface of the closed casing and at the input end of the spray mesh port.

[0020] The technical solution of the present invention has the following advantages compared with the prior art:

[0021] The present invention discloses a double-sided coating device for silicon steel plates. A twisting, swinging telescopic arm engages a locking buckle at one end with the top corner of the silicon steel plate located in the plate locking groove. After fixing this, the device uses the connection point between the limiting rod and the swinging telescopic arm as a support point. The swinging telescopic arm is then pulled and swung to pull the bottom corner of the silicon steel plate out from the inside of the plate locking groove, overlapping it onto the top surface of the silicon steel plate limiting platform. Subsequent pulling further engages the silicon steel plate and the silicon steel plate limiting platform. The docking point serves as a support point. Under the drag of the swing telescopic arm, the silicon steel plate is swung, causing it to detach from the inner wall of the limiting hollow strip. A relatively stable triangular shape is formed between the swing telescopic arm, the bottom corner of the silicon steel plate, and the limiting platform of the silicon steel plate. Due to its length and inclined surface, the silicon steel plate will be dragged back and swung. The side of the silicon steel plate is secured by snap-fit ​​buckles to prevent it from collapsing due to shaking when it is upright, thus avoiding impact injuries to employees.

[0022] The present invention discloses a double-sided coating device for silicon steel plates. Two movable frames, a second and a first, slide on the inner walls of an upper and lower track. The first movable frame, using the inclined surface of an upper ramp, is raised, allowing it to slide into the inner wall of a closed casing. A paint sprayer then fills the guide tube with coating liquid, guiding it through the spray nozzle into the closed casing. As the coating liquid flows out, it is propelled upwards on the inner surface of the upper inclined groove, utilizing the slope of the groove. Increasing the diffusion area and range of the coating liquid, the gas inside the closed casing is absorbed through the return mesh. When the air flows, it will drive the coating liquid in the space to flow. The flowing coating liquid will pass through the gaps between the silicon steel plates, thereby coating multiple silicon steel plates. Excess coating liquid will slide off under its own gravity and the vertical angle of the silicon steel plates. With the help of the leakage mesh plate, it will penetrate into the inner wall of the silicon steel plate limiting platform. Then, the coating liquid inside the silicon steel plate limiting platform is discharged into the closed casing for recycling using the liquid guiding chute and the liquid outlet.

[0023] The present invention discloses a double-sided coating device for silicon steel plates. After the surface of the silicon steel plate is coated, it is moved towards the outlet. The moving rollers on the outer surface of the overlapping support plate preferentially overlap the surface of the flowing ramp. The inclined surface of the flowing ramp is used to swing the overlapping support plate. The swinging of the overlapping support plate is used to accumulate some residual coating liquid on the surface of the silicon steel plate and the residual coating liquid inside the silicon steel plate limiting platform to one side and drain it through the drain port. However, when the overlapping support plate passes the surface of the closed shell, the elastic wire is used to swing and compress the overlapping support plate upward. The effect is that the moving frame is snapped into the lower track after passing through the opening.

[0024] The present invention discloses a double-sided coating device for silicon steel plates. The silicon steel plate is transported and placed on the top surface of a drain mesh plate. Firstly, the bottom corner of the silicon steel plate is snapped into the inner surface of the plate clamping groove. Once the plate clamping groove defines the position of the silicon steel plate, the silicon steel plate is swung towards the drain mesh plate and the gap between the two limiting hollow strips, using the inner corner of the groove as a support point. This snaps the bottom surface of the silicon steel plate into the inner wall of the limiting hollow strips, ensuring the silicon steel plate completely overlaps the top surface of the drain mesh plate and is perpendicular to it, thus standing upright.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0042] Reference Figures 1 to 10 As shown, a double-sided coating device for silicon steel plates according to the present invention includes:

[0043] A support frame 12 is installed at the outer edge of the closed housing 11;

[0044] The movable frame 13 is slidably sleeved on the inner wall of the support frame 12;

[0045] Silicon steel plate 14 is movably attached to the inner side wall of the top of the mobile frame 13;

[0046] A silicon steel plate anti-sway peeling unit is provided on the top outer surface of the mobile frame 13. The silicon steel plate anti-sway peeling unit includes a silicon steel plate limiting platform 1310. A steel plate snap-fit ​​groove a4 is opened on one side edge of the inner side of the silicon steel plate limiting platform 1310. An overlap strip a3 is fixedly connected to the other side wall of the silicon steel plate limiting platform 1310 at the top edge. A limiting rod a7 is fixedly installed on the outer side wall of the silicon steel plate limiting platform 1310 at one side edge of the steel plate snap-fit ​​groove a4. A swing telescopic arm a8 is movably sleeved on the outer surface of the second position rod a7. A snap-lock a9 is fixedly connected to one end of the swing telescopic arm a8 and is movably sleeved on the outer surface of the top of the silicon steel plate 14. A drain mesh plate a5 is detachably installed on the inner wall of the bottom of the silicon steel plate limiting platform 1310 and located at one edge position. A limiting hollow strip a6 is fixedly connected to the top surface of the drain mesh plate a5 and is movably attached to the two sides of the silicon steel plate 14.

[0047] When using the swing telescopic arm a8, snap-fit ​​lock a9, limit rod two a7, steel plate snap-fit ​​groove a4, limit hollow strip a6, and silicon steel plate limit platform 1310 provided by the present invention, after the surface of the silicon steel plate 14 is coated, the swing telescopic arm a8 is twisted to snap the snap-fit ​​lock a9 at one end of it onto the top corner surface of the silicon steel plate 14 located in the steel plate snap-fit ​​groove a4. After fixing it, the swing telescopic arm a8 is pulled and swung with the connection between the limit rod two a7 and the swing telescopic arm a8 as the support point, so that the bottom corner of the silicon steel plate 14 is pulled out from the inside of the steel plate snap-fit ​​groove a4 and overlapped on the top surface of the silicon steel plate limit platform 1310. On the surface, under subsequent pulling, with the joint between the silicon steel plate 14 and the silicon steel plate limiting platform 1310 as the support point, the silicon steel plate 14 is swung under the drag of the swing telescopic arm a8, causing the silicon steel plate 14 to fall off the inner wall of the limiting hollow strip a6. A relatively stable triangular shape is formed between the swing telescopic arm a8, the bottom corner of the silicon steel plate 14, and the silicon steel plate limiting platform 1310. Due to its length and inclined surface, the silicon steel plate 14 will be dragged and swung back. The side of the silicon steel plate 14 is locked and fixed by the snap-fit ​​lock a9 to prevent the silicon steel plate 14 from collapsing due to shaking when it is upright, thus causing impact injury to employees.

[0048] Furthermore, such as Figure 5 - Figure 10 As shown, a liquid guiding groove a1 is provided on the inner side wall of the bottom of the silicon steel plate limiting platform 1310. A drain outlet a2 is provided on the inner side wall of the silicon steel plate limiting platform 1310 at the lowest point of the liquid guiding groove a1. The drain outlet a2 is located at the lowest point of the overlapping strip a3. The top surface of the liquid leakage mesh plate a5 is fixedly connected to the two sides of the silicon steel plate 14.

[0049] When using the steel plate slot a4, the drain mesh plate a5, and the limiting hollow strip a6 provided by this invention, the silicon steel plate 14 is transported and placed on the top surface of the drain mesh plate a5. The bottom corner of the silicon steel plate 14 is first secured to the inner surface of the steel plate slot a4. Once the steel plate slot a4 defines the position of the silicon steel plate 14, it is only necessary to use the inner corner of the steel plate slot a4 as a support point and swing the silicon steel plate 14 towards the gap between the drain mesh plate a5 and the two limiting hollow strips a6. This secures the bottom surface of the silicon steel plate 14 into the inner wall of the limiting hollow strip a6, ensuring that the silicon steel plate 14 completely overlaps the top surface of the drain mesh plate a5, making it completely perpendicular to the top surface of the drain mesh plate a5, thus erecting it.

[0050] Furthermore, such as Figure 1 - Figure 10 As shown, a limiting collar 131 is fixedly connected to the top surface of the mobile frame 13 at both side edges. A limiting rod 132 is movably sleeved on the inner wall of the limiting collar 131. Multiple sets of V-shaped brackets 133 are fixedly connected to the two end surfaces of the limiting rod 132. An overlapping support plate 134 is fixedly connected to the top surface of the V-shaped bracket 133. Symmetrically installed moving rollers 135 are provided on both side surfaces of the overlapping support plate 134. A silicon steel plate limiting platform 1310 is positioned on the top surface of the overlapping support plate 134 at the middle position. Elastic wires 136, located at both side edges of the silicon steel plate limiting platform 1310, are fixedly connected to the top surface of the overlapping support plate 134. An elastic wire is fixedly connected to the top of the elastic wire 136. A support column 137 is provided, and an overlapping top plate 138 is fixedly connected to the top of the support column 137. A mobile frame 139 is fixedly installed on the top surface of the overlapping top plate 138 at the middle position. An upward moving track 121 is fixedly connected to the top two sides of the support frame 12, which is movably sleeved on the outer surface of the mobile frame 139. A downward moving track 122 is provided on the bottom surface of the upward moving track 121 at a position perpendicular to the bottom. One end of the downward moving track 122 is fixedly connected to the bottom two sides of the closed housing 11. An opening 123 is provided at the position where the downward moving track 122 connects with the bottom surface of the closed housing 11. An upward ramp 124 is fixedly connected to the inner surface of the downward moving track 122 at the position where it connects with the closed housing 11.

[0051] When the overlapping support plate 134, movable roller 135, silicon steel plate limiting platform 1310, and flow ramp 116 provided by the present invention are used, after the surface of the silicon steel plate 14 is coated, it is moved towards the outlet. The movable roller 135 on the outer surface of the overlapping support plate 134 preferentially overlaps the surface of the flow ramp 116. The inclined surface of the flow ramp 116 is used to swing the overlapping support plate 134. The swing of the overlapping support plate 134 is used to accumulate some residual coating liquid on the surface of the silicon steel plate 14 and the residual coating liquid inside the silicon steel plate limiting platform 1310 to one side and drain it through the drain port a2. However, when the overlapping support plate 134 crosses the surface of the closed sleeve 11, the elastic wire 136 is used to swing and compress the overlapping support plate 134 upward, and then through the opening 123 to engage the movable frame 13 into the downward track 122.

[0052] Furthermore, such as Figure 1 - Figure 4 As shown, a return mesh port 113 and a spray mesh port 114 are respectively provided on the inner walls of both sides of the closed casing 11. An upward inclined groove 115 is provided on the inner wall of the closed casing 11 and at the bottom edge of the spray mesh port 114. A flow ramp 116 is fixedly installed on the inner walls of both sides of the closed casing 11. A downward inclined track 117 is provided on the outer surfaces of both sides of the closed casing 11 and at the edges of both sides of the downward track 122. A paint sprayer 111 is provided on the outer surface of the closed casing 11 and at the outer edge of the return mesh port 113. A liquid guide pipe 112 is fixedly connected to the output end of the paint sprayer 111 and is movably connected to the top outer surface of the closed casing 11. The other end of the liquid guide pipe 112 is fixedly connected to the outer surface of the closed casing 11 and at the input end of the spray mesh port 114.

[0053] The upper moving track 121, lower moving track 122, spray nozzle 114, upper inclined groove 115, return mesh 113, and silicon steel plate limiting platform 1310 provided by this invention, when in use, slide on the inner wall surfaces of the upper moving track 121 and lower moving track 122 in conjunction with the second moving frame 139 and the first moving frame 13. The inclined surface of the upper inclined ramp 124 raises the first moving frame 13, allowing it to slide into the inner wall surface of the closed casing 11. The paint sprayer 111 fills the inside of the liquid guide tube 112 with coating liquid, which flows through the spray nozzle 114 into the inside of the closed casing 11. As the coating liquid flows out, the inclined surface of the upper inclined groove 115 coats the inside of the casing. The coating liquid flows upward on the inner surface of the inclined groove 115, thereby increasing the diffusion area and range of the coating liquid. Then, the gas inside the closed shell 11 is absorbed through the return mesh 113. When the air flows, it will drive the coating liquid in the space to flow. The flowing coating liquid will pass through the gaps between the silicon steel plates 14, thereby coating multiple silicon steel plates 14. Excess coating liquid slides down under its own gravity and the vertical angle of the silicon steel plates 14. With the help of the leakage mesh a5, it penetrates into the inner wall of the silicon steel plate limiting platform 1310. Then, the coating liquid inside the silicon steel plate limiting platform 1310 is discharged into the closed shell 11 for recycling using the liquid guiding inclined groove a1 and the liquid discharge port a2.

[0054] The working principle of this auxiliary loading and unloading device will be explained in detail below.

[0055] The silicon steel plate 14 is transported and placed on the top surface of the drain mesh plate a5. The bottom corner of the silicon steel plate 14 is first attached to the inner surface of the steel plate slot a4. After the steel plate slot a4 defines the position of the silicon steel plate 14, the silicon steel plate 14 is swung towards the gap between the drain mesh plate a5 and the two limiting hollow strips a6, with the inner corner of the steel plate slot a4 as the support point. The bottom surface of the silicon steel plate 14 is attached to the inner wall of the limiting hollow strip a6, so that the silicon steel plate 14 is completely overlapped on the top surface of the drain mesh plate a5, making the silicon steel plate 14 completely perpendicular to the top surface of the drain mesh plate a5, thus standing upright.

[0056] After the surface of the silicon steel plate 14 is coated, it is moved toward the outlet. The moving roller 135 on the outer surface of the overlapping support plate 134 first overlaps with the surface of the flow ramp 116. The inclined surface of the flow ramp 116 is used to swing the overlapping support plate 134. The swing of the overlapping support plate 134 causes some residual coating liquid on the surface of the silicon steel plate 14 and the residual coating liquid inside the silicon steel plate limiting platform 1310 to accumulate to one side and be discharged through the drain port a2. However, when the overlapping support plate 134 passes the surface of the closed sleeve 11, the elastic wire 136 is used to swing and compress the overlapping support plate 134 upward. This results in the effect of inserting the moving frame 13 into the downward track 122 after passing through the opening 123.

[0057] The movable frame 139 and movable frame 13 slide on the inner walls of the upper track 121 and lower track 122. The inclined surface of the upper ramp 124 raises movable frame 13, allowing it to slide into the inner wall of the closed housing 11. The paint sprayer 111 fills the liquid guide tube 112 with coating liquid, guiding it through the spray nozzle 114 into the closed housing 11. As the coating liquid flows out, the inclined surface of the upper sloping slot 115 causes it to flow upwards on the inner surface of the upper sloping slot 115, thereby increasing the coating liquid concentration. The diffusion area and range are such that the gas inside the closed shell 11 is absorbed through the return mesh 113. When the air flows, it will drive the coating liquid in the space to flow. The flowing coating liquid will pass through the gap between the silicon steel plates 14, thereby coating multiple silicon steel plates 14. The excess coating liquid slides down under its own gravity and the vertical angle of the silicon steel plates 14. With the help of the leakage mesh plate a5, it penetrates into the inner wall of the silicon steel plate limiting platform 1310. Then, the coating liquid inside the silicon steel plate limiting platform 1310 is discharged into the closed shell 11 for recycling using the liquid guiding chute a1 and the liquid discharge port a2.

[0058] Twist the swing telescopic arm a8 to engage the locking buckle a9 at one end with the top corner of the silicon steel plate 14 located in the steel plate locking groove a4, and secure it. After securing it, use the connection between the limiting rod a7 and the swing telescopic arm a8 as a support point, and pull and swing the swing telescopic arm a8 to pull the bottom corner of the silicon steel plate 14 out from the inside of the steel plate locking groove a4, and overlap it on the top surface of the silicon steel plate limiting platform 1310. Under subsequent pulling, use the joint between the silicon steel plate 14 and the silicon steel plate limiting platform 1310 as a support point. The silicon steel plate 14 is swung by the swing telescopic arm a8, causing it to detach from the inner wall of the limiting hollow strip a6. A relatively stable triangular shape is formed between the swing telescopic arm a8, the bottom corner of the silicon steel plate 14, and the silicon steel plate limiting platform 1310. Due to its length and inclined surface, the silicon steel plate 14 will be dragged back and swung. The side of the silicon steel plate 14 is secured by the snap-fit ​​lock a9 to prevent it from collapsing due to shaking when it is upright, thus avoiding impact injuries to employees.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
