Description
Technical Field
[0001] The utility model relates to the technical field of coating spraying devices for non-oriented silicon steel, and particularly relates to a coating spraying device for non-oriented silicon steel. Background Art
[0002] Non-oriented silicon steel is a silicon-iron alloy with very low carbon content. In the steel plate after deformation and annealing, its grains are randomly oriented. In the production process of non-oriented silicon steel, an environmental protection coating needs to be sprayed on the surface of non-oriented silicon steel to ensure the insulation, rust prevention, workability, etc. of non-oriented silicon steel.
[0003] The traditional spraying method is to respectively arrange a spray pipe and a coating roller on the upper and lower sides in the strip steel conveying direction. The nozzles on the two spray pipes spray the coating on the two coating rollers. When the strip steel passes through the two coating rollers, the two coating rollers are driven to rotate, and the coating on the coating rollers is evenly coated on the surface of the strip steel. Since the spray pipe and the spray head are usually fixedly arranged, the spraying range is fixed, which easily leads to the uneven coating on the coating roller. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a coating spraying device for non-oriented silicon steel is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A coating spraying device for non-oriented silicon steel, including a bottom plate, two columns are fixedly connected to the bottom plate, two rectangular columns are fixedly connected to the columns, a coating roller is jointly arranged on the two rectangular columns located on the same horizontal plane, a strip steel is jointly arranged in the two coating rollers, two spray pipes are jointly arranged on the two columns, two nozzles are fixedly connected to the spray pipes, the spray pipes are communicated with a coating tank filled with spray coating, a uniform structure is jointly arranged on the two columns, the uniform structure is mainly composed of two rectangular plates, the two rectangular plates are respectively fixedly connected to the two columns, a first sliding groove is opened on the rectangular plate, a first sliding block is slidably connected in the first sliding groove, and the first sliding block is fixedly connected to the spray pipe.
[0006] The effects achieved by the above components are as follows: The nozzle sprays the coating in the coating tank onto the coating roller, the strip steel is passed through between the two coating rollers, and the two coating rollers are driven to rotate under the action of friction, so that the upper and lower surfaces of the strip steel are coated with the coating. When spraying the coating, the first sliding block can be reciprocally slid, driving the spray pipe to reciprocally slide, so that the entire coating roller is evenly sprayed with the coating, thus avoiding the situation that because the current spray pipe and the spray head are usually fixedly arranged, the spraying range is fixed, which easily leads to the uneven coating on the coating roller.
[0007] Preferably, a threaded rod is rotatably connected in the first sliding groove, the threaded rod is threadedly connected to the first slider, a first motor is fixedly connected to the rectangular plate, and an output shaft of the first motor is fixedly connected to the threaded rod.
[0008] The effects achieved by the above components are as follows: When the first motor is started, the output shaft of the first motor drives the threaded rod to rotate. Since the first slider is limited and slides in the threaded rod, the rotation of the threaded rod will drive the first slider to slide. Therefore, by rotating the first motor forward and backward, the first slider can be driven to slide back and forth, making the operation more convenient.
[0009] Preferably, a material receiving groove is fixedly connected to the rectangular plate located above, and the notch of the material receiving groove is attached to the coating roller located above.
[0010] The effects achieved by the above components are as follows: During the spraying process, the excess coating above will fall into the material receiving groove, and the coating that falls during the rotation of the coating roller will evenly adhere to the coating roller, thus avoiding waste of the coating.
[0011] Preferably, a material receiving box is fixedly connected to the bottom plate, and baffles are respectively fixedly connected to both sides of the material receiving groove.
[0012] The effects achieved by the above components are as follows: The baffles can prevent the coating in the material receiving groove from flowing out from both sides, and the excess coating on the lower coating roller will fall into the material receiving box, further avoiding waste of the coating.
[0013] Preferably, a sliding groove is formed in the rectangular column, a sliding block is slidably connected in the sliding groove, a first rotating shaft is rotatably connected to the sliding block, the first rotating shaft is fixedly connected to the coating roller, a spring is fixedly connected to the sliding block, and one end of the spring is fixedly connected to the inner wall of the sliding groove.
[0014] The effects achieved by the above components are as follows: When the coating roller applies the coating to the strip steel, the spring is in a contracted state. Therefore, the elastic force of the spring's rebound acts on the sliding block, causing both coating rollers to tightly press on the strip steel, thereby enhancing the coating effect.
[0015] Preferably, a flattening structure is provided on the bottom plate. The flattening structure mainly consists of two support columns. The two support columns are respectively fixedly connected to the bottom plate, and two flattening rollers are jointly provided on the two support columns. The two flattening rollers are respectively located on the upper and lower surfaces of the strip steel.
[0016] The effects achieved by the above components are as follows: The strip steel coated with the coating passes between the two flattening rollers, and the two flattening rollers can roll-press the coating on the strip steel to make the coating more flat.
[0017] Preferably, a rectangular block is fixedly connected to the support column. A second sliding groove is formed in the rectangular block. Two second sliding blocks are slidably connected in the second sliding groove. A second rotating shaft is rotatably connected to the second sliding block. The second rotating shaft is fixedly connected to the flattening roller.
[0018] The effects achieved by the above components are as follows: By sliding the second sliding block, the flattening roller can be driven to slide up and down, and thus the distance between the flattening roller and the strip steel can be adjusted according to the coating requirements.
[0019] Preferably, a bidirectional screw rod is rotatably connected in the second sliding groove. The bidirectional screw rod is threadedly connected to the two second sliding blocks. The two sections of threads on the bidirectional screw rod have opposite directions. A second motor is fixedly connected to the rectangular block. The output shaft of the second motor is fixedly connected to the bidirectional screw rod.
[0020] The effects achieved by the above components are as follows: When the second motor is started, the output shaft of the second motor drives the bidirectional screw rod to rotate. Since the second sliding block is limited to slide in the second sliding groove, the rotation of the bidirectional screw rod will drive the two second sliding blocks to slide. Also, because the two sections of threads on the bidirectional screw rod have opposite directions, the rotation of the bidirectional screw rod will drive the two second sliding blocks to approach or move away from each other.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows: In the present utility model, by setting a uniform structure, when spraying the coating, the first sliding block can be reciprocally slid, driving the spraying pipe to reciprocally slide, and then the entire coating roller is evenly sprayed with the coating. When the first motor is started, the output shaft of the first motor drives the threaded rod to rotate. Since the first sliding block is limited to slide in the threaded rod, the rotation of the threaded rod will drive the first sliding block to slide. Therefore, by rotating the first motor forward and backward, the first sliding block can be driven to reciprocally slide, making the operation more convenient. During the spraying process, the excess coating above will fall into the material receiving groove. The coating that falls during the rotation of the coating roller will be evenly attached to the coating roller, thus avoiding waste of the coating. The baffle can prevent the coating in the material receiving groove from flowing out from both sides. The excess coating on the lower coating roller will fall into the material receiving box, further avoiding waste of the coating. When the coating roller applies the coating to the strip steel, the spring is in a contracted state. Therefore, the elastic force of the spring's rebound acts on the sliding block, causing both coating rollers to tightly press on the strip steel, thereby enhancing the coating effect and avoiding the situation that the spraying range of the current spray pipe and spray head is usually fixed, easily resulting in uneven coating on the coating roller.

Detailed implementation manners
[0027] Example 1, as Figure 1 shown, a spraying device for non-oriented silicon steel coating includes a bottom plate 1, two columns 2 are fixedly connected to the bottom plate 1, two rectangular columns 9 are fixedly connected to the columns 2, a coating roller 3 is jointly arranged on the two rectangular columns 9 at the same horizontal plane, a strip steel 4 is jointly arranged in the two coating rollers 3, two spraying pipes 5 are jointly arranged on the two columns 2, two nozzles 6 are fixedly connected to the spraying pipes 5, and the spraying pipe 5 is communicated with a coating box filled with spraying paint.
[0028] Refer to Figure 2 and Figure 4, a uniform structure 7 is jointly arranged on two columns 2. The uniform structure 7 is mainly composed of two rectangular plates 71. The two rectangular plates 71 are respectively fixedly connected to the two columns 2. A first sliding groove 72 is formed in the rectangular plate 71. A first sliding block 73 is slidably connected in the first sliding groove 72. The first sliding block 73 is fixedly connected to the spraying pipe 5. The spray head 6 sprays the paint in the paint tank onto the paint roller 3. The strip steel 4 is passed through between the two paint rollers 3. Under the action of friction, the two paint rollers 3 are driven to rotate. Thus, the two paint rollers 3 apply paint to the upper and lower surfaces of the strip steel 4. When spraying paint, the first sliding block 73 can be reciprocally slid, driving the spraying pipe 5 to reciprocally slide. Thus, the entire paint roller 3 is evenly sprayed with paint, avoiding the situation that the spraying range of the current spray pipe and spray head is usually fixedly set, so the paint on the coating roller is prone to be uneven. A threaded rod 74 is rotatably connected in the first sliding groove 72. The threaded rod 74 is threadedly connected to the first sliding block 73. A first motor 75 is fixedly connected to the rectangular plate 71. The output shaft of the first motor 75 is fixedly connected to the threaded rod 74. When the first motor 75 is started, the output shaft of the first motor 75 drives the threaded rod 74 to rotate. Since the first sliding block 73 is limited and slides in the threaded rod 74, the rotation of the threaded rod 74 will drive the first sliding block 73 to slide. Thus, by rotating the first motor 75 forward and backward, the first sliding block 73 can be driven to reciprocally slide, making the operation more convenient. A receiving groove 76 is fixedly connected to the upper rectangular plate 71. The notch of the receiving groove 76 is fitted with the upper paint roller 3. During the spraying process, the excess paint above will fall into the receiving groove 76. The paint falling during the rotation of the paint roller 3 will evenly adhere to the paint roller 3, thus avoiding the waste of paint. A receiving box 711 is fixedly connected to the bottom plate 1. Baffles 77 are respectively fixedly connected to both sides of the receiving groove 76. The baffles 77 can prevent the paint in the receiving groove 76 from flowing out from both sides. The excess paint on the lower paint roller 3 will fall into the receiving box 711, further avoiding the waste of paint. A sliding groove 78 is formed in the rectangular column 9. A sliding block 79 is slidably connected in the sliding groove 78. A first rotating shaft 710 is rotatably connected to the sliding block 79. The first rotating shaft 710 is fixedly connected to the paint roller 3. A spring 712 is fixedly connected to the sliding block 79. One end of the spring 712 is fixedly connected to the inner wall of the sliding groove 78. When the paint roller 3 applies paint to the strip steel 4, the spring 712 is in a contracted state. Thus, the resilient force of the spring 712 acts on the sliding block 79, making the two paint rollers 3 tightly press on the strip steel 4, thereby enhancing the coating effect.
[0029] Refer to Figure 1 and Figure 3, a flattening structure 8 is provided on the bottom plate 1. The flattening structure 8 is mainly composed of two support columns 81. The two support columns 81 are respectively fixedly connected to the bottom plate 1. Two flattening rollers 82 are commonly provided on the two support columns 81. The two flattening rollers 82 are respectively located on the upper and lower surfaces of the strip steel 4. The strip steel 4 coated with paint passes through the middle of the two flattening rollers 82. The two flattening rollers 82 can roll-press the paint on the strip steel 4 to make the paint smoother. A rectangular block 83 is fixedly connected to the support column 81. A second chute 84 is provided in the rectangular block 83. Two second sliders 85 are slidably connected in the second chute 84. A second rotating shaft 86 is rotatably connected to the second slider 85. The second rotating shaft 86 is fixedly connected to the flattening roller 82. By sliding the second slider 85, the flattening roller 82 can be driven to slide up and down. Furthermore, the distance between the flattening roller 82 and the strip steel 4 can be adjusted according to the paint requirements. A bidirectional screw 87 is rotatably connected in the second chute 84. The bidirectional screw 87 is threadedly connected to the two second sliders 85. The two thread directions on the bidirectional screw 87 are opposite. A second motor 88 is fixedly connected to the rectangular block 83. The output shaft of the second motor 88 is fixedly connected to the bidirectional screw 87. When the second motor 88 is started, the output shaft of the second motor 88 drives the bidirectional screw 87 to rotate. Since the second slider 85 is limited to slide in the second chute 84, the rotation of the bidirectional screw 87 will drive the two second sliders 85 to slide. Also, because the two thread directions on the bidirectional screw 87 are opposite, the rotation of the bidirectional screw 87 will drive the two second sliders 85 to approach or move away from each other.
[0030] Working principle: The nozzle 6 sprays the paint in the paint tank onto the paint roller 3. The strip steel 4 is passed through between the two paint rollers 3, and the two paint rollers 3 are driven to rotate under the action of friction, so that the upper and lower surfaces of the strip steel 4 are coated with paint by the two paint rollers 3. When spraying paint, the first slider 73 can slide reciprocally, driving the spraying pipe 5 to slide reciprocally, and then evenly spraying the entire paint roller 3 with paint, thus avoiding the situation that the spraying range of the current spray pipe and spray head is usually fixed, which easily leads to uneven paint on the coating roller. Start the first motor 75, and the output shaft of the first motor 75 drives the threaded rod 74 to rotate. Since the first slider 73 is limited to slide in the threaded rod 74, the rotation of the threaded rod 74 will drive the first slider 73 to slide. Therefore, by rotating the first motor 75 forward and backward, the first slider 73 can be driven to slide reciprocally, making the operation more convenient. During the spraying process, the excess paint above will fall into the material receiving groove 76, and the paint falling during the rotation of the paint roller 3 will evenly adhere to the paint roller 3, thus avoiding waste of paint. The baffle 77 can prevent the paint in the material receiving groove 76 from flowing out from both sides. The excess paint on the lower paint roller 3 will fall into the material receiving box 711, further avoiding waste of paint. When the paint roller 3 coats the strip steel 4, the spring 712 is in a contracted state, so the elastic force of the spring 712 acts on the sliding block 79, making the two paint rollers 3 tightly press on the strip steel 4, thus enhancing the coating effect. The strip steel 4 coated with paint passes through between the two flattening rollers 82. The two flattening rollers 82 can roll-press the paint on the strip steel 4 to make the paint more flat. The distance between the flattening roller 82 and the strip steel 4 can be adjusted according to the paint requirements by sliding the second slider 85 to drive the flattening roller 82 to slide up and down. Start the second motor 88, and the output shaft of the second motor 88 drives the bidirectional screw 87 to rotate. Since the second slider 85 is limited to slide in the second chute 84, the rotation of the bidirectional screw 87 will drive the two second sliders 85 to slide. And because the two sections of the thread on the bidirectional screw 87 have opposite directions, the rotation of the bidirectional screw 87 will drive the two second sliders 85 to approach or move away from each other.
