Description

Technical Field

[0001] This utility model relates to the field of color-coated steel sheet processing technology, and more specifically, to a coating device for color-coated steel sheet processing. Background Technology

[0002] Color-coated steel sheets are building materials that have been coated on the surface of metal sheets. The base materials are usually cold-rolled steel sheets, galvanized steel sheets (including hot-dip galvanized and electro-galvanized), aluminum-magnesium-manganese alloy sheets, etc. These base materials are pre-treated before coating, which allows the surface of the color-coated steel sheets to be printed with specified colors or patterns.

[0003] The coating equipment for color-coated steel sheets mainly consists of a processing table, coating rollers, winding rollers, and raw material rollers. When color-coated steel sheets need to be coated, the raw material rollers containing alloy plates are installed on the processing table, and the surface of the raw material is coated by the coating rollers. Then, the coated color-coated steel sheets are wound up by the winding rollers.

[0004] In the prior art, when coating color-coated steel sheets, if the viscosity of the coating is too high or the coating process is improper, the coating may accumulate at the edges of the color-coated steel sheets, forming rough edges, which is not conducive to the aesthetics of the edges of the color-coated steel sheets. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a coating device for color-coated steel plate processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating device for color-coated steel sheet processing, comprising a processing table, a bracket fixedly connected to the top of the processing table, a material roller rotatably connected to one side of the bracket, a coating roller rotatably connected to the inner wall of the bracket, the coating roller being disposed on one side of the material roller, a steering roller rotatably connected to the inner wall of the bracket, the steering roller being disposed on the side of the coating roller away from the material roller, a raw material roller rotatably connected to the inner wall of the bracket, the raw material roller being disposed at the bottom of the steering roller, a take-up roller rotatably connected to one side of the bracket, a paint tank fixedly connected to the top of the processing table, the material roller being disposed in the paint tank, a mounting plate fixedly connected to one side of the bracket, a first motor fixedly connected to one side of the mounting plate, a bidirectional screw fixedly connected to the output end of the first motor, a nut threadedly connected to the outer wall of the bidirectional screw, a second motor fixedly connected to the top of the nut, a cleaning roller fixedly connected to the output end of the second motor, a cleaning pad sleeved on the outer wall of the cleaning roller, and a limiting component for limiting the movement trajectory of the nut being provided at the top of the processing table.

[0007] Furthermore, the limiting component includes a limiting frame, which is fixedly connected to the top of the processing table, and a limiting rod is fixedly connected to the bottom of the nut, the limiting rod being slidably connected to the inner wall of the limiting frame.

[0008] Furthermore, a side rod is fixed to one side of the nut, and a scraper is fixed to the top of the side rod, with the scraper positioned on one side of the cleaning pad.

[0009] Furthermore, a mounting frame is fixed to one side of the top of the processing table, a collection box is provided on the inner wall of the mounting frame, a handle is fixed to one side of the collection box, and the collection box is located at the bottom of the scraper.

[0010] Furthermore, a magnet is fixed to the inner wall of the mounting frame, an iron block is fixed to the side of the collection box away from the handle, the iron block is located on one side of the magnet, and a ramp is provided at the top of the collection box.

[0011] The technical effects and advantages of the coating device for color-coated steel plate processing of this utility model are as follows:

[0012] The first motor is started to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it will cause the two sets of nuts to slide. By setting the limit component, the movement trajectory of the nuts can be limited until the space between the two sets of nuts is consistent with the width of the substrate. Then the second motor is started, which drives the cleaning roller set at the output end to rotate. When the cleaning roller rotates, the edge of the substrate can be wiped by the cleaning pad. Excess paint on the edge of the substrate can be wiped away, preventing the paint from forming burrs after drying. This solves the problem of burrs easily forming at the edge during the coating process of color coated plates. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1-5 A coating apparatus for processing color-coated steel sheets includes a processing table 1. A support 2 is fixedly connected to the top of the processing table 1. A feed roller 3 is rotatably connected to one side of the support 2. A coating roller 4 is rotatably connected to the inner wall of the support 2 and is located on one side of the feed roller 3. A guide roller 6 is rotatably connected to the inner wall of the support 2 and is located on the side of the coating roller 4 away from the feed roller 3. A raw material roller 7 is rotatably connected to the inner wall of the support 2 and is located at the bottom of the guide roller 6. A take-up roller 22 is rotatably connected to one side of the support 2. The processing table... A paint tank 5 is fixed to the top of the support 1. The conveyor roller 3 is disposed in the paint tank 5. An mounting plate 8 is fixed to one side of the support 2. A first motor 9 is fixed to one side of the mounting plate 8. A bidirectional screw 10 is fixed to the output end of the first motor 9. A nut 11 is threadedly connected to the outer wall of the bidirectional screw 10. A second motor 12 is fixed to the top of the nut 11. A cleaning roller 13 is fixed to the output end of the second motor 12. A cleaning pad is sleeved on the outer wall of the cleaning roller 13. A limiting component for limiting the movement trajectory of the nut 11 is provided at the top of the processing table 1.

[0023] To address the issue of rough edges forming during the coating process of color-coated steel sheets, when coating is required, the substrate can be placed on the raw material roller 7 and guided to one side by the guide roller 6. Simultaneously, the coating roller 4, conveyor roller 3, guide roller 6, raw material roller 7, and take-up roller 22 are activated to transfer the substrate to one side. Since the bottom of the conveyor roller 3 is located inside the paint tank 5, the paint in the paint tank 5 adheres to it during rotation and is transferred to the coating roller 4 on one side through contact. The rotation of the coating roller 4 coats the substrate on the guide roller 6 with paint, thus coating the surface of the substrate. After the paint on the substrate surface is dried, it can pass through the take-up roller 22. The color-coated sheet is wound up. During transportation, the first motor 9 is started, which drives the bidirectional screw 10 on one side to rotate. When the bidirectional screw 10 rotates, it causes the two sets of nuts 11 to slide. By setting a limit component, the movement trajectory of the nuts 11 can be limited until the space between the two sets of nuts 11 is consistent with the width of the substrate. Then, the second motor 12 is started, which drives the cleaning roller 13 set at the output end to rotate. When the cleaning roller 13 rotates, the edge of the substrate can be wiped by the cleaning pad to remove excess paint from the edge of the substrate and prevent the paint from forming burrs after drying.

[0024] Reference Figure 3 The limiting component includes a limiting frame 14, which is fixedly connected to the top of the processing table 1. A limiting rod 15 is fixedly connected to the bottom of the nut 11, and the limiting rod 15 is slidably connected to the inner wall of the limiting frame 14.

[0025] When the nut 11 moves, it will drive the bottom limiting rod 15 to move together. The limiting rod 15 is located inside the limiting frame 14. Therefore, the moving trajectory of the limiting rod 15 and the nut 11 can be limited by the limiting frame 14 to prevent the nut 11 from deviating when moving.

[0026] Reference Figure 4 A side rod 16 is fixedly connected to one side of the nut 11, and a scraper 17 is fixedly connected to the top of the side rod 16. The scraper 17 is disposed on one side of the cleaning pad.

[0027] By providing a side rod 16 on one side of the nut 11, it is easy to install the scraper 17 on the side rod 16. By providing the scraper 17, when the cleaning roller 13 rotates, the scraper 17 can scrape off the paint accumulated on one side of the cleaning pad, preventing too much paint on the cleaning pad from affecting the cleaning effect.

[0028] Reference Figure 5 A mounting frame 18 is fixedly connected to one side of the top of the processing table 1. A collection box 19 is provided on the inner wall of the mounting frame 18. A handle is fixedly connected to one side of the collection box 19. The collection box 19 is located at the bottom of the scraper 17.

[0029] By setting an installation frame 18 at the top of the processing table 1, it is easy to place the collection box 19 inside the installation frame 18. After the scraper 17 scrapes off the excess paint, it will gradually fall into the collection box 19 by gravity, making it easy to collect the scraped paint. The handle makes it easy to take out the collection box 19.

[0030] Reference Figure 3 A magnet 20 is fixed to the inner wall of the mounting frame 18, and an iron block 21 is fixed to the side of the collection box 19 away from the handle. The iron block 21 is located on one side of the magnet 20, and a ramp is provided at the top of the collection box 19.

[0031] By setting a magnet 20 inside the mounting frame 18, when the collection box 19 is installed into the mounting frame 18, the magnet 20 will attract the iron block 21 set on one side of the collection box 19, which makes it easier to install the collection box 19 securely. The slope set above the collection box 19 also helps to collect the paint towards the center.

[0032] Working Principle: To address the issue of burrs forming at the edges during the coating process of color-coated steel sheets, when coating is required, the substrate is placed on the raw material roller 7 and guided to one side by the guide roller 6. Simultaneously, the coating roller 4, conveyor roller 3, guide roller 6, raw material roller 7, and take-up roller 22 are activated to transfer the substrate to one side. Since the bottom of the conveyor roller 3 is located inside the paint tank 5, the paint in the paint tank 5 adheres to it during rotation and is transferred to the coating roller 4 on one side through contact. The rotation of the coating roller 4 coats the paint onto the guide roller. The substrate on the 6th layer is coated with paint, and after the paint on the substrate surface is dried, the color-coated sheet can be wound up by the winding roller 22. When transporting the color-coated sheet, the first motor 9 can be started, which drives the bidirectional screw 10 on one side to rotate. When the bidirectional screw 10 rotates, it will cause the two sets of nuts 11 to slide. When the nuts 11 move, they will drive the bottom limiting rod 15 to move together. The limiting rod 15 is set inside the limiting frame 14, so the limiting frame 14 can be used to limit the limiting rod 15 and the screw. The movement trajectory of the nut 11 is limited to prevent it from shifting during movement. The movement trajectory of the nut 11 can be limited until the space between the two sets of nuts 11 is consistent with the width of the substrate. Then, the second motor 12 is started, driving the cleaning roller 13 at the output end to rotate. As the cleaning roller 13 rotates, the edges of the substrate are wiped by the cleaning pad, removing excess paint and preventing burrs after drying. A scraper 17 is provided to wipe the edges of the substrate as the cleaning roller 13 rotates. 17. Scrape off the paint accumulated on one side of the cleaning pad to prevent excessive paint on the cleaning pad from affecting the cleaning effect. When the collection box 19 is installed into the mounting frame 18, the magnet 20 will attract the iron block 21 set on one side of the collection box 19, which makes it easier to install the collection box 19 securely. The slope set on the top of the collection box 19 also helps to collect the paint towards the center. After the scraper 17 scrapes off the excess paint, it will gradually fall into the collection box 19 by gravity, which makes it easy to collect the scraped paint. The handle makes it easy to take out the collection box 19.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
