Description

Technical Field

[0001] This utility model relates to the field of metal coating drying technology, specifically to a device for drying metal surface coatings. Background Technology

[0002] Metal coating drying equipment is used to accelerate the drying and curing of coatings on metal surfaces. In coating application processes, metal surfaces are frequently coated to achieve effects such as corrosion protection and aesthetic enhancement. After the coating is applied, a drying process is required to ensure the coating dries and cures quickly. Traditional metal coating drying equipment is mostly fixed drying method. Fixed drying method involves placing material trays directly inside the drying room and drying them by static spreading or hanging. This method is prone to problems such as local overheating or uneven heating, resulting in inconsistent coating curing quality and defects such as cracking and wrinkling. Therefore, a device for drying metal surface coating is proposed. Utility Model Content

[0016] like Figures 1-6 As shown, this utility model provides a technical solution: a device for drying paint on metal surfaces, including a stand 1. The stand 1 provides an installation environment for the entire device, and the bottom of the stand 1 is a counterweight block, which serves as the core support for the entire device to improve the stability of the device operation. It can also be fixed to the ground with bolts.

[0017] like Figures 1-6 As shown in the embodiment of this application, a rotating shaft 9 is provided on the inner side of the support frame 1. Circular grooves are symmetrically arranged on the rotating shaft 9. A side plate 10 is provided within the circular grooves. A drying lamp 11 is provided on the inner side of the edge of the side plate 10. The drying lamp 11 is used to dry the coating on the metal surface. Specifically, a shaft hole is pre-drilled above the support frame 1 for installing the rotating shaft 9. One end of the rotating shaft 9 is connected to a motor. The rotating shaft 9 is rotatably connected to the support frame 1. The circular groove on the rotating shaft 9 is adapted to the side plate 10. The side plate 10 is located within the circular groove and is rotatably connected to the rotating shaft 9. The side plate 10 is a circular plate, and its inner surface is a reflective surface, capable of reflecting the light irradiated by the drying lamp 11, thereby uniformly drying the metal. Drying lamps 11 are distributed circumferentially on the side plate 10. The drying lamps 11 use infrared heating, etc., and their power is adjusted according to the drying requirements, enabling rapid application of heat to the metal surface.

[0018] like Figures 1-6 As shown in the embodiment of this application, the outer wall of the rotating shaft 9 is symmetrically provided with rotating wheels 4, and a frame 5 is provided between the rotating wheels 4. The frame 5 is used to hold the metal to be dried. Specifically, the rotating wheels 4 are fixedly provided on the outer wall of the rotating shaft 9, and the rotating wheels 4 rotate synchronously with the rotating shaft 9. The frame 5 is provided between the rotating wheels 4, and the frame 5 moves around the center of the rotating shaft 9.

[0019] like Figures 1-6As shown in the embodiment of this application, the rotating wheels 4 are connected by docking shafts 6. The docking shafts 6 are equidistantly distributed on the rotating wheels 4 with the axis of the rotating wheels 4 as the center. End caps 7 are provided on the outer walls of both ends of the docking shafts 6. Specifically, the docking shafts 6 are provided through the inner edge of the rotating wheel 4. The two ends of the docking shafts 6 pass through the rotating wheel 4 and are connected to the end caps 7. The docking shafts 6 are circumferentially distributed on the rotating wheels 4, so that the frame 5 is evenly distributed circumferentially between the rotating wheels 4. The end caps 7 are threaded to the two ends of the docking shafts 6, and the docking shafts 6 are keyed to the circular holes provided on the edge of the rotating wheels 4, so that the rotating wheels 4 can synchronously drive the docking shafts 6 to rotate, and it is convenient to replace the frame 5.

[0020] like Figures 1-6 As shown in the embodiment of this application, annular grooves are symmetrically provided on the axial direction of the docking shaft 6, and uprights 8 are provided in the annular grooves. A frame 5 is provided at the bottom of the uprights 8. Specifically, the annular grooves on the docking shaft 6 match the uprights 8. The uprights 8 are composed of a ring and a vertical rod. The uprights 8 rotate around the docking shaft 6 during the rotation of the rotating wheel 4, and under the action of the metal in the frame 5, they can maintain a horizontal state under the action of gravity. The uprights 8 and the frame 5 are fixedly connected. The frame 5 has a striped structure. The stripes are designed to stably place the metal workpieces and not block the heat radiation of the drying lamp 11. Under the action of the stripes, the metal workpieces in the frame 5 can be dried from multiple angles.

[0021] like Figures 1-6 As shown in the embodiment of this application, the side plates 10 are connected by annular rolls 3, and the drying lamps 11 are distributed in a circumferential array along the inner surface of the annular rolls 3. Specifically, the side plates 10 are connected by annular rolls 3, and the annular rolls 3 are open structures and are not complete circles. The opening of the annular rolls 3 allows workers to load and unload the dried metal.

[0022] like Figures 1-6 As shown in the embodiment of this application, an annular sleeve 2 is provided on the outer side of the side plate 10, and a slot corresponding to the annular sleeve 2 is opened on the opposite side surface of the upright frame 1. Specifically, a slot is opened on the bottom of the upright frame, and the slot matches the annular sleeve 2 to provide its installation environment. The annular sleeve 2 and the side plate 10 are threadedly connected. Furthermore, by adjusting the contact distance between the annular sleeve 2 and the side plate 10, the concentricity of the through hole on the annular sleeve 2 and the circular hole on the side plate 10 can be indirectly adjusted.

[0023] like Figures 1-6As shown in the embodiment of this application, the side plate 10 is provided with a circular hole that matches the drying lamp 11, and the annular sleeve 2 is provided with a through hole that matches the circular hole on the side plate 10. Specifically, the diameter of the annular sleeve 2 is slightly larger than that of the side plate 10. With the cooperation of the side plate 10, the annular sleeve 2, and the annular roll 3, a semi-sealed drying operation scene can be formed. The opening on the annular roll 3 facilitates the loading and unloading of materials by the workers. A dustproof curtain can be installed at the opening to prevent excessive heat leakage during the drying process and to prevent a large amount of external dust from entering the heating area. The through hole on the annular sleeve 2 is aligned with the circular hole on the side plate 10, which facilitates the passage of the power cord of the drying lamp 11. The diameter of the through hole is smaller than that of the circular hole, which can indirectly limit the displacement of the drying lamp 11.

[0024] like Figures 1-6 As shown in the embodiments of this application, a polytetrafluoroethylene (Teflon) coating is sprayed on the surface of the frame 5, or stainless steel is used and mirror polished. The Teflon coating is resistant to high temperature and has low surface tension, making it difficult for the electrophoretic wet film to adhere. Even if a small amount of residue remains, it can be blown off after drying, without affecting the reuse of the frame.

[0025] The working principle of this utility model is as follows: The painted metal workpiece is placed inside the frame 5. The frame 5 is suspended on the annular groove of the docking shaft 6 by the upright 8. The upright 8 can rotate with the rotating wheel 4 and remain vertical, so that the workpiece is stable and unobstructed. The annular roll 3 between the side plates 10 and the drying lamps 11 (infrared heating lamps) distributed in the inner circumference form a semi-enclosed heating space. The reflective layer on the inner surface of the side plate 10 enhances the heat accumulation. During drying, the motor drives the rotating shaft 9 to rotate, which in turn drives the rotating wheel 4 to rotate. During the rotation of the rotating wheel 4, the frame 5 remains vertically downward due to gravity, causing the workpiece to slowly rotate within the annular heating space. At the same time, the drying lamps 11 in each area of ​​the annular roll 3 continuously radiate heat, so that each area of ​​the workpiece surface is evenly heated, and the coating gradually dries and solidifies. After drying, frame 5 rotates with wheel 4 to the opening position, and staff can remove the workpiece to complete the drying process.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
