Technical Field
[0001] This utility model relates to the field of color-coated steel sheet production technology, specifically to a correction structure for a color-coated steel sheet spraying device. Background Technology
[0002] Color-coated steel sheet, also known as color-coated steel sheet, is a composite material that combines decoration and functionality. It is formed by coating one or more layers of organic coating on the surface of a metal substrate and then curing it. Its production steps can be divided into pretreatment stage, spraying stage and post-treatment stage. The pretreatment stage involves leveling, cleaning, surface treatment and drying of the steel sheet to avoid impurities on the steel sheet surface and provide a good adhesion base for the coating. The spraying stage involves using a spraying device to spray primer, dry primer, spray topcoat and dry topcoat on the steel sheet. The post-treatment stage involves cooling, surface treatment, quality inspection, coiling and slitting of the dried and cured steel sheet.
[0003] In the prior art, the steel plate goes through a pretreatment stage and is transported to the spraying channel by a conveyor on the spraying device. Then, the paint is delivered to the nozzle by the feeding system and the paint is evenly sprayed onto the surface of the steel plate to form a primer. After drying and curing, the topcoat is sprayed and finally dried and cured again to complete the spraying stage of the color-coated steel plate.
[0004] In actual production, steel plates are transported to the spraying channel via a conveyor on the spraying device. Due to the washing and drying processes during the pretreatment stage and the vibration of the conveyor belt, the steel plates are deviated by the vibration and the force of the treatment stage, resulting in the center line of the steel plate not being consistent with the center line of the spraying channel. This causes uneven coating edges or missed coatings during spraying. Therefore, a correction structure for the color-coated steel plate spraying device is proposed to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a correction structure for a color-coated steel sheet spraying device. This structure has the advantage of correcting the centerline of the steel sheet, solving the problem that when the steel sheet is transported from the pretreatment stage to the spraying device via a conveyor belt, the steel sheet undergoes washing and drying processes during the pretreatment stage, and is affected by conveyor belt vibration. This causes the steel sheet to shift due to vibration and the forces exerted during the pretreatment stage, resulting in the centerline of the steel sheet being inconsistent with the centerline of the spraying channel. Consequently, this leads to uneven coating edges or missed areas during spraying.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a correction structure for a color-coated steel sheet spraying device, comprising a guide component and a correction component disposed on the spraying device, wherein the spraying device is provided with a conveyor table that is respectively connected to the guide component and the correction component;
[0007] The correction assembly includes a mounting plate fixedly installed on the conveyor table, a connecting frame fixedly installed on the mounting plate, a guide plate hinged on the conveyor table to prevent the color-coated sheet from sticking to the edge, a connecting plate hinged to one end of the guide plate, a connecting rod fixedly installed on the connecting plate, and the connecting rod slidably connected to the mounting plate, and an elastic component provided on the connecting rod to assist the sliding of the connecting rod, and the elastic component is connected to the connecting frame.
[0008] The elastic component includes a boss washer that is slidably mounted on the outer surface of the connecting rod, and a spring is fixedly connected to one side of the boss washer, and the spring is sleeved on the outer surface of the connecting rod. A flat washer is fixedly connected to one end of the spring, and the flat washer is fixedly mounted on the outer surface of the connecting rod.
[0009] Furthermore, the mounting plate is provided with a guide groove, and the connecting rod is slidably connected to the guide groove. The connecting frame is provided with a limiting groove on the side near the mounting plate, and the limiting groove is adapted to the boss gasket. There are two guide components, which are symmetrically distributed on the conveyor table.
[0010] Furthermore, the correction assembly includes two correction plates for correcting the position of the color-coated sheet, and a connecting rod component is provided on the conveyor table and fixedly connected to the two correction plates. An electric push rod is fixedly installed on the conveyor table, and the telescopic end of the electric push rod is connected to the connecting rod component.
[0011] Furthermore, the connecting rod assembly includes two vertical rods, which are respectively fixedly connected to two correction plates. A horizontal rod is hinged to each of the two vertical rods, and a mounting rod is hinged to each of the two horizontal rods. The mounting rod is fixedly connected to the telescopic end of the electric push rod.
[0012] Furthermore, two rectangular slots are provided on the conveyor platform, and one end of the vertical rod passes through the rectangular slot, with the rectangular slot and the vertical rod slidably connected.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] The correction structure of this color-coated steel plate spraying device is equipped with a guide component and a correction component. The elastic component transmits the correction force through flexible buffering, avoiding rigid contact that could cause scratches or indentations to the pre-treatment layer or coated layer on the steel plate surface. At the same time, it prevents the steel plate from sticking too much to the edge of the conveyor table, which would cause the correction component to malfunction. It also achieves dynamic and flexible correction of the steel plate position. Furthermore, by using a connecting rod component and an electric push rod, it controls two correction plates to synchronously push the offset edge of the steel plate back to the center line of the spraying channel, ensuring that the center line of the steel plate coincides with the center line of the spraying channel, thus eliminating the problem of uneven coating edges or missed coating caused by offset.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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: Please refer to Figure 1-4 The correction structure of a color-coated steel sheet spraying device in this embodiment includes a guide component 1 and a correction component 2 disposed on the spraying device, and a conveyor table 3 disposed on the spraying device and connected to the guide component 1 and the correction component 2 respectively.
[0022] Example 2: Please refer to Figure 1-4 Based on Embodiment 1, the correction component 2 includes a mounting plate 11 fixedly installed on the conveyor table 3, a connecting frame 12 fixedly installed on the mounting plate 11, a guide plate 13 hinged on the conveyor table 3 to prevent the color-coated sheet from sticking to the edge, a connecting plate 14 hinged to one end of the guide plate 13, a connecting rod 15 fixedly installed on the connecting plate 14, and the connecting rod 15 slidably connected to the mounting plate 11, and an elastic component 16 provided on the connecting rod 15 to assist the sliding of the connecting rod 15, and the elastic component 16 is connected to the connecting frame 12;
[0023] The elastic component 16 includes a boss washer 161 that is slidably mounted on the outer surface of the connecting rod 15. A spring 162 is fixedly connected to one side of the boss washer 161 and the spring 162 is sleeved on the outer surface of the connecting rod 15. A flat washer 163 is fixedly connected to one end of the spring 162 and the flat washer 163 is fixedly mounted on the outer surface of the connecting rod 15.
[0024] The mounting plate 11 has a guide groove 111, and the connecting rod 15 is slidably connected to the guide groove 111. The connecting frame 12 has a limiting groove 121 on the side near the mounting plate 11, and the limiting groove 121 is adapted to the boss gasket 161. There are two guide components 1, which are symmetrically distributed on the conveyor table 3. By using the cooperation between the limiting groove 121 and the boss gasket 161, the boss gasket 161 will not detach from the connecting frame 12 during the sliding process.
[0025] Using the above technical solution, when the edge of the steel plate deviates and contacts the guide plate 13, the steel plate applies a pushing force to the guide plate 13. The guide plate 13 rotates around the hinge point with the conveyor table 3, and drives the connecting rod 15 to slide along the guide groove 111 of the mounting plate 11 through the connecting plate 14. When the connecting rod 15 slides, the flat washer 163 compresses the spring 162. The spring 162 pushes the boss washer 161 to fit against the limiting groove 121 of the connecting frame 12. The elastic potential energy of the spring 162 is converted into a reverse pushing force on the guide plate 13. The guide plate 13 applies a gentle corrective force to the edge of the steel plate through this pushing force, buffering the vibration impact and pushing the slightly deviated steel plate back to a position close to the center, initially suppressing the deviation, and at the same time preventing the steel plate from excessively adhering to the edge of the conveyor table 3.
[0026] Example 3: Please refer to Figure 1-4 Based on Embodiment 2, the correction component 2 includes two correction plates 21 for correcting the position of the color-coated plate. The conveyor table 3 is provided with a connecting rod component 22 that is fixedly connected to the two correction plates 21. An electric push rod 23 is fixedly installed on the conveyor table 3, and the telescopic end of the electric push rod 23 is connected to the connecting rod component 22.
[0027] The connecting rod component 22 includes two vertical rods 221, which are fixedly connected to two correction plates 21 respectively. Each vertical rod 221 is hinged with a horizontal rod 222, and each horizontal rod 222 is hinged with a mounting rod 223. The mounting rod 223 is fixedly connected to the telescopic end of the electric push rod 23. The telescopic end of the electric push rod 23 pushes the mounting rod 223 of the connecting rod component 22 to translate. The mounting rod 223 drives the two hinged horizontal rods 222 to rotate around the node. The other end of the horizontal rod 222 drives the vertical rod 221 to slide along the rectangular groove of the conveyor table 3, thereby driving the two correction plates 21 to move.
[0028] In addition, two rectangular slots are provided on the conveyor table 3, and one end of the vertical rod 221 passes through the rectangular slot. The rectangular slot and the vertical rod 221 are slidably connected. The horizontal rod 222 drives the vertical rod 221 to slide along the rectangular slot of the conveyor table 3, which can ensure the stability of the movement direction.
[0029] Using the above technical solution, after the steel plate passes through the guide assembly 1, the electric push rod 23 on the drive conveyor table 3 is activated. Its telescopic end pushes the mounting rod 223 of the connecting rod assembly 22 to move in a straight line. The mounting rod 223 drives the two hinged horizontal bars 222 to rotate. The horizontal bars 222 drive the vertical bars 221 to slide along the rectangular groove of the conveyor table 3. The two vertical bars 221 respectively drive the corresponding correction plates 21 to move symmetrically towards the center or outward. The correction plates 21 contact the edge of the steel plate and apply a pushing force to accurately push the steel plate to the center line position of the spraying channel.
[0030] The working principle of the above embodiments is as follows:
[0031] The correction structure of the color-coated steel plate spraying device has the following characteristics: when the edge of the steel plate deviates and contacts the guide plate 13, the steel plate applies a pushing force to the guide plate 13. The guide plate 13 rotates around the hinge point with the conveyor table 3, and drives the connecting rod 15 to slide along the guide groove 111 of the mounting plate 11 through the connecting plate 14. When the connecting rod 15 slides, the flat washer 163 compresses the spring 162. The spring 162 pushes the boss washer 161 to fit against the limiting groove 121 of the connecting frame 12. The elastic potential energy of the spring 162 is converted into a reverse pushing force on the guide plate 13. The guide plate 13 applies a gentle corrective force to the edge of the steel plate through this pushing force, buffers the vibration impact, and pushes the slightly deviated steel plate back to a position close to the center, initially suppressing the deviation, while preventing the steel plate from excessively sticking to the edge of the conveyor table 3.
[0032] After the steel plate passes through the guide assembly 1, the electric push rod 23 on the drive conveyor table 3 is activated. Its telescopic end pushes the mounting rod 223 of the connecting rod assembly 22 to move in a straight line. The mounting rod 223 drives the two hinged horizontal bars 222 to rotate. The horizontal bars 222 drive the vertical bars 221 to slide along the rectangular groove of the conveyor table 3. The two vertical bars 221 respectively drive the corresponding correction plates 21 to move symmetrically towards the center or outward. The correction plates 21 contact the edge of the steel plate and apply a pushing force to accurately push the steel plate to the center line position of the spraying channel.
