Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a metal composite plate surface coating device. Background Technology

[0002] Metal composite panels are layered composite materials formed by metallurgically bonding two or more metal materials with different properties at the interface using specific composite technologies. Their structure typically includes a base layer and a cladding layer: the base layer is often made of high-strength, moderate-cost steel such as structural steel or low-alloy steel, providing support and structural stability; the cladding layer, depending on the requirements, uses metals with corrosion resistance, wear resistance, or high-temperature resistance, such as stainless steel, titanium alloys, or nickel-based alloys, to impart the core functional characteristics of the panel.

[0003] Coating metal composite panels is a key process for protecting the performance, appearance, and extending the lifespan of the panels. On the one hand, it can isolate contaminants during production, transportation, and storage, preventing oxidation or corrosion and ensuring the smoothness and performance stability of the panels. On the other hand, it can reduce surface scratches and bumps during subsequent processing, especially for decorative or precision-purpose panels, ensuring the integrity of the appearance.

[0004] For example, the patent with publication number CN221717830U discloses a metal sheet coating mechanism, including a coating machine body, a mounting frame, a first electric telescopic rod, a fixing plate, and a heat insulation box. Heat is generated in the heat insulation box through a heating resistor, and the heat insulation material can retain most of the heat in the box. The fan blows the hot air in the box out to exchange heat with the metal sheet, allowing more heat to be transferred to the surface of the sheet, thereby increasing the heat absorption of the sheet and improving the heating efficiency.

[0005] The aforementioned solution suffers from limitations in air outlet width adjustment, making it difficult to adapt to the coating requirements of metal sheets of varying widths. Currently, the air outlets of the insulation box have a fixed structure, resulting in a consistently uniform airflow range that cannot be adjusted according to the actual width of the metal sheet. When coating narrow metal sheets, the air outlets in the excess areas on both sides of the insulation box continuously blow out hot air. This hot air not only fails to reach the sheet surface but also dissipates into the surrounding environment, wasting heat and potentially causing aging of the surrounding components of the coating machine due to prolonged heat exposure. Conversely, when coating wide metal sheets, the fixed air outlet width is insufficient to cover the entire surface, easily leading to insufficient heating at the edges. Therefore, a surface coating device for metal composite panels needs to be designed.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] This utility model provides a metal composite panel surface coating device to solve the problems of low glue splicing efficiency of plastic flooring materials, visible seams in the interlocking splicing, easy accumulation of dirt and deformation of the flooring.

[0008] This utility model embodiment adopts the following technical solution: a metal composite plate surface coating device. It mainly includes a conveyor; a coating assembly mounted on the conveyor, the coating assembly including a mounting frame fixed on the conveyor, and a horizontally arranged auxiliary plate fixed inside the mounting frame. There is an installation gap between the auxiliary plate and the top of the inner wall of the mounting frame. A heating part for uniformly distributing hot air to the metal composite plate is provided within the installation gap. An adjusting part for adjusting the air outlet range is provided on the heating part. A coating part for coating the metal composite plate is provided on the mounting frame, and a flattening part for flattening the surface of the coated metal composite plate is provided on the auxiliary plate.

[0009] Furthermore, the heating element includes a second servo motor fixed to the auxiliary plate and located within the installation gap. The telescopic end of the second servo motor passes through the auxiliary plate and is fixed to a heat insulation box. A resistor is installed inside the heat insulation box. An arc-shaped vent plate is provided at the bottom of the heat insulation box. The vent plate has vent holes perpendicular to the vent plate, allowing heat to be evenly dissipated through the vent holes. A fan is installed on the mounting frame, and the air outlet of the fan is connected to the side of the heat insulation box via a flexible hose.

[0010] Furthermore, the adjustment unit includes a support rod fixed to the end face of the heat insulation box. The support rod is L-shaped, and a horizontally arranged screw is threaded to the vertical end of the support rod. A baffle plate is bearing-connected to one end of the screw. The baffle plate is made of heat insulation material, has an arc-shaped structure, and is in contact with the bottom surface of the vent plate. Limiting rods are fixed on both sides of the heat insulation box, and the two ends of the baffle plate slide between two sets of limiting rods. A scale is fixed to the side of one set of limiting rods.

[0011] Furthermore, the heat insulation box is provided with an installation part, which includes end rods installed at both ends of the heat insulation box. Pipe clamps are fixed on the upper surface of the vent plate near both ends. The pipe clamps are fixedly connected by bolts by two sets of relatively fitted semi-rings. The vent plate is held and fixed on the end rods by the pipe clamps at both ends.

[0012] Furthermore, the mounting frame has two sets of crossbars, and the coating section includes two sets of bearing seats fixed on the two sets of crossbars. A coating roller is arranged between the two sets of bearing seats, and there is a gap between the coating roller and the conveyor for the metal composite plate to pass through.

[0013] Furthermore, the flattening part includes a servo motor fixed on the auxiliary plate and located in the installation gap. The telescopic end of the servo motor passes through the auxiliary plate and is fixed with a fixing block. A concave frame is fixed on the bottom surface of the fixing block, and a flattening roller is mounted on the concave frame.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] The metal composite panel surface coating device uses a conveyor as the basic transport carrier. Within the installation gap formed by the mounting frame and auxiliary plate of the coating assembly, the heating unit can evenly deliver hot air to the metal composite panel. The adjustable section of the heating unit can flexibly adjust the air outlet range. When coating narrow panels, the adjustable section narrows the air outlet width to prevent hot air from escaping from excess areas on both sides, reducing heat waste and preventing aging of surrounding components due to long-term heat exposure. When coating wide panels, the air outlet width is widened to ensure full coverage of hot air and avoid insufficient heating at the edges. Simultaneously, the coating section on the mounting frame completes the coating operation, and the flattening section on the auxiliary plate eliminates coating wrinkles, improving adaptability to panels of different widths and ensuring coating quality.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-5 As shown, the metal composite plate surface coating device provided in this embodiment of the present invention includes a conveyor 1, which is usually conveyed by belt conveyor to smoothly transport the metal composite plate, and a coating component 2 is provided on the conveyor 1. The coating component 2 includes a mounting frame 21 fixed on the conveyor 1, and a horizontally arranged auxiliary plate 22 is fixed inside the mounting frame 21. There is an installation gap between the auxiliary plate 22 and the top of the inner wall of the mounting frame 21.

[0028] A heating element is provided within the installation gap. This heating element includes a servo motor 218 fixed on the auxiliary plate 22 and located within the installation gap. During actual operation, the servo motor 218 can be controlled to extend and retract. The extension end of the servo motor 218 passes through the auxiliary plate 22 and is fixed to a heat insulation box 27. A resistor (not shown in the figure) is provided inside the heat insulation box 27. The resistor generates heat when energized, providing the required heat energy for film coating. An arc-shaped vent plate 28 is provided at the bottom of the heat insulation box 27. The vent plate 28 has vent holes perpendicular to the vent plate 28 (not shown in the figure). Heat can be evenly dissipated through the vent holes. A fan 219 is provided on the mounting frame 21. The fan 219 can continuously provide airflow. The air outlet of the fan 219 is connected to the side of the heat insulation box 27 through a flexible hose 220. The flexible hose 220 has good flexibility and can be flexibly changed with the movement of the heat insulation box 27 to ensure stable airflow delivery.

[0029] like Figures 4-5As shown, adjustment sections are provided at both ends of the heat insulation box 27. In actual coating operations, these adjustment sections can flexibly adjust the air outlet range to accommodate metal composite panels of different widths. The adjustment section includes a support rod 214 fixed to the end face of the heat insulation box 27 by fasteners. The fastener connection is stable and reliable, and easy to install, disassemble and maintain. The support rod 214 is L-shaped, and a horizontally arranged screw 215 is threaded to the vertical end of the support rod 214. One end of the screw 215 is connected to a baffle plate 210 with a bearing. The baffle plate 210 is made of heat insulation material, which can effectively block heat loss from the side, avoid energy waste, and prevent surrounding components from malfunctioning due to heat.

[0030] The shield 210 also has an arc-shaped structure and is attached to the bottom surface of the breathable plate 28. The attached design can minimize heat leakage from the gap between the two. Limiting rods 29 are fixed on both sides of the heat insulation box 27. The limiting rods 29 provide guidance for the movement of the shield 210 and ensure that it slides smoothly in a straight line. The two ends of the shield 210 slide between the two sets of limiting rods 29. At the same time, a scale 211 is fixed on the side of one set of limiting rods 29. The staff can intuitively and accurately control the movement distance of the shield 210 according to the scale of the scale 211.

[0031] In actual operation, the operator can precisely control the movement distance of the baffle plate 210 by rotating the screw 215. The baffle plate 210 is connected to the bearing at one end of the screw 215 so that when the screw 215 rotates, the baffle plate 210 can move smoothly along the straight line of the limit rod 29 without rotating itself. This, together with the scale 211, allows for precise adjustment of the air outlet width to match metal composite panels of different widths, thereby improving the adaptability and quality of the coating.

[0032] In order to disassemble and clean the breathable panel 28, which is prone to dust accumulation and affects breathability after long-term use, such as... Figures 4-5 As shown, an installation part is provided on the heat insulation box 27. The installation part includes end rods 212 fixedly installed at both ends of the heat insulation box 27, and pipe clamps 213 are fixed on the upper surface of the vent plate 28 near both ends. The pipe clamps 213 are fixedly connected by bolts by two sets of relatively fitted semi-rings, so that the vent plate 28 is held and fixed on the end rods 212 by the pipe clamps 213 at both ends. In actual production, after the vent plate 28 has been used for a period of time, it will be covered with dust and other impurities. At this time, the staff can disassemble and clean the vent plate 28 by disassembling the adjustment part and the installation part in sequence. After cleaning, the vent plate 28 is reinstalled in reverse order to ensure that the vent plate 28 continues to work efficiently, thereby ensuring the heating and coating effect of the entire coating device.

[0033] Continue to refer to, for example Figures 4-5As shown, the mounting frame 21 has two sets of crossbars (not shown in the figure). A coating section is provided on the crossbars of the mounting frame 21. The coating section includes two sets of bearing seats 216 fixed on the two sets of crossbars, and a coating roller 217 is provided between the two sets of bearing seats 216. The bearing seats 216 can provide stable rotational support for the coating roller 217. In actual production, the metal composite plate needs to pass between the coating roller 217 and the conveyor 1 to complete the coating. There is a gap between the coating roller 217 and the conveyor 1 for the metal composite plate to pass through. In actual use, if it is necessary to adapt to metal composite plates of different thicknesses, this gap can be achieved by adjusting and replacing the coating roller 217 of different diameters. This can flexibly meet diverse coating needs and ensure the coating quality of metal composite plates of different specifications.

[0034] like Figures 1-3 As shown, a flattening part is provided on the auxiliary plate 22. The flattening part includes a servo motor 23 fixed on the auxiliary plate 22 and located in the installation gap. The telescopic end of the servo motor 23 passes through the auxiliary plate 22 and is fixed with a fixing block 24. A concave frame 25 is fixed on the bottom surface of the fixing block 24, and a flattening roller 26 is mounted on the concave frame 25 with a bearing. The bearing connection allows the flattening roller 26 to rotate flexibly. After the metal composite plate is coated, the flattening roller 26 can flatten the coating on its surface to avoid wrinkles and other problems, ensuring that the surface of the coated metal composite plate is flat and improving product quality. In actual use, the servo motor 23 can precisely control the telescopic movement to adjust the height of the flattening roller 26.

[0035] Working principle: In actual lamination operation, the metal composite plate to be laminated is first placed on the belt of conveyor 1. After the conveyor 1 is started, it drives the metal composite plate to the lamination assembly 2 at a stable speed. According to the thickness of the metal composite plate to be laminated, the operator replaces the lamination roller 217 with the corresponding diameter in advance, so that the lamination roller 217 and the conveyor 1 form a gap that matches the thickness of the plate, ensuring that the plate can pass smoothly and the lamination roller 217 can contact the surface of the plate. At the same time, according to the width of the plate, by rotating the screws 215 of the adjusting parts at both ends of the heat insulation box 27, the screws 215 and the support rod 214 are threaded together to drive the shielding plate 210 to slide smoothly along the limiting rod 29. The operator refers to the scale 211 on the side of the limiting rod 29 to adjust the shielding plate 210 to a suitable position so that the air outlet width of the vent plate 28 matches the width of the plate, avoiding heat waste or insufficient heating of the plate edge.

[0036] Subsequently, the heating and flattening sections are activated. In the heating section, the resistor inside the heat insulation box 27 generates heat when energized, and the fan 219 starts simultaneously. Outside air enters the hose 220 through the fan 219 and is then transported to the heat insulation box 27 through the hose 220. The air mixes with the heat generated by the resistor to form hot air, which is then evenly blown onto the surface of the metal composite plate being conveyed below through the vents on the vent plate 28, preheating the surface of the plate and preparing it for improved film adhesion. If there are differences in plate thickness, the servo motor 218 can finely adjust the height of the heat insulation box 27 through its telescopic movement to ensure a stable distance between the hot air and the plate surface, resulting in consistent heating. When the metal composite plate enters the gap between the film coating roller 217 and the conveyor 1, the film coating roller 217 rotates synchronously under the influence of the plate, gradually adhering the film it is wrapped around to the preheated plate surface. The preheated temperature enhances the adhesion of the film coating, ensuring a tight bond between the film and the plate.
