Description

Technical Field

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

[0002] Electrophoretic coating is a widely used process for metal surface treatment. It involves depositing coating particles onto the workpiece surface under the influence of an electric field, forming a uniform and dense coating. After electrophoretic coating, the workpiece needs to be dried to cure the coating and improve its adhesion, corrosion resistance, and aesthetics. Traditional drying equipment often uses static drying methods, where the electrophoretically coated parts remain stationary during the drying process, and hot air is blown in a fixed direction towards the parts. This can easily lead to localized overheating or insufficient drying of the electrophoretically coated parts. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a surface coating drying device for electrophoretic parts, thereby solving the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A surface coating drying device for electrophoretic parts includes a base and a drying cylinder. The drying cylinder is located on top of the base. A mesh cylinder is fixedly mounted on the inner wall of the drying cylinder by two supports.

Air inlet fans are installed on the inner walls of the two air inlet frames at equal intervals. Heating wires are fixedly mounted on the inner walls of the two air inlet frames. Bearings are fixedly mounted on the outer walls of both ends of the drying cylinder. Fixed rings are sleeved on the outer rings of the two bearings. The outer walls of the fixed rings are fixedly connected to the top outer wall of the base by supports.

[0006] As a preferred embodiment of the surface coating drying device for electrophoretic parts, two exhaust frames are fixedly provided on the other side of the drying cylinder through an opening, and exhaust grilles are fixedly provided on the inner wall of the exhaust frames at equal intervals.

[0008] As a preferred embodiment of the surface coating drying device for electrophoretic parts, two vertically upward positioning plates are fixedly provided at the top two ends of the base, and the adjacent positioning plates are movably connected to a rotating shaft through an opening, and two pulleys are respectively installed on the outer wall of the two rotating shafts.

[0009] As a preferred embodiment of the surface coating drying device for electrophoretic parts, the outer wall of the pulley located on the same straight line is fitted with belt strips, the tops of the two belt strips are located on the same straight line, and the two belt strips pass through the inner wall of the mesh cylinder.

[0010] As a preferred embodiment of the surface coating drying device for electrophoretic parts, a motor fixing cover is fixedly provided on one side of the outer wall of the positioning plate, and a drive motor is installed on the inner wall of the motor fixing cover. The output shaft of the drive motor is fixedly connected to one end of the shaft of the pulley.

[0011] The beneficial effects of this utility model are:

[0025] like Figures 1 to 5 As shown, this utility model provides a surface coating drying device for electrophoretic parts, which mainly includes a base 1, a drying cylinder 2, a mesh cylinder 3, an air inlet frame 4, an air outlet frame 7, a toothed ring 9, a bearing 10, a fixing ring 11, a support base 12, a speed limiting motor 13, a drive gear 14, a positioning plate 15, a pulley 16, a motor fixing cover 17, and a belt strip 18.

[0026] Specifically, in this embodiment, the drying cylinder 2 is installed on the top of the base 1. The inner wall of the drying cylinder 2 is fixedly provided with a mesh cylinder 3 by two brackets. The mesh cylinder 3 is used to place the electrophoresis components. The outer walls of both ends of the drying cylinder 2 are fixedly provided with bearings 10. The outer ring of the bearing 10 is sleeved with a fixing ring 11. The fixing ring 11 is fixedly connected to the top outer wall of the base 1 by the brackets. The outer wall of the drying cylinder 2 is fixedly provided with a toothed ring 9. The top outer wall of the base 1 is fixedly provided with a support seat 12. The top outer wall of the support seat 12 is fixedly provided with a speed limiting motor 13. The output shaft of the speed limiting motor 13 is fixedly provided with a drive gear 14 by a coupling. The drive gear 14 meshes with the toothed ring 9 to drive the drying cylinder 2 to rotate.

[0027] Two air inlet frames 4 are fixedly installed on one side of the outer wall of the drying cylinder 2 through an opening. Air inlet fans 5 and heating wires 6 are installed on the inner wall of the air inlet frames 4 at equal intervals. The air inlet fans 5 draw in outside air, and after being heated by the heating wires 6, the hot air enters the interior of the drying cylinder 2. Two exhaust frames 7 are fixedly installed on the other side of the drying cylinder 2 through an opening. Exhaust grilles 8 are fixedly installed on the inner wall of the exhaust frames 7 at equal intervals to discharge the moisture and waste gas generated during the drying process.

[0028] More specifically, in this embodiment, two vertically upward positioning plates 15 are fixedly provided at the top two ends of the base 1. Adjacent positioning plates 15 are movably connected to rotating shafts through openings. Two pulleys 16 are respectively installed on the outer walls of the two rotating shafts. Belt strips 18 are sleeved on the outer walls of the pulleys 16 located on the same straight line. A motor fixing cover 17 is fixedly provided on one side of the outer wall of the positioning plate 15. A drive motor is installed on the inner wall of the motor fixing cover 17. The output shaft of the drive motor is fixedly connected to one end of the rotating shaft of the pulley 16, driving the pulley 16 to rotate, thereby driving the belt strips 18 to move. The tops of the two belt strips 18 are located on the same straight line, and the two belt strips 18 pass through the inner wall of the mesh cylinder 3. The tops of the two belt strips 18 transport the electrophoresis components inside the mesh cylinder 3.

[0029] Working principle and usage process of this utility model:

[0030] In use, the operator places the electrophoretic coating drying device on top of two belts 18. The drive motor rotates the pulley 16, which in turn moves the belts 18. The belts 18 pass through the inner wall of the mesh cylinder 3, smoothly conveying the electrophoretic coating into the drying cylinder 2. Once the coating is fully inside the drying cylinder 2, the drive motor stops, the belts 18 stop moving, and the intake fan 5 and heating wire 6 inside the intake frame 4 are activated. The intake fan 5 draws in outside air, which is heated by the heating wire 6 to form hot air that enters the drying cylinder 2. The hot air passes through the mesh of the mesh cylinder 3, ensuring even airflow. The speed-limiting motor is then activated. The speed-limiting motor 13 drives the drying cylinder 2 to rotate slowly through the meshing of the drive gear 14 and the gear ring 9. The rotation of the drying cylinder 2 drives the mesh cylinder 3, so that the electrophoretic parts are heated evenly during the drying process, avoiding local overheating or uneven drying. The moisture and exhaust gas generated during the drying process are discharged through the exhaust grille 8 in the exhaust frame 7. The design of the exhaust grille 8 can effectively prevent external dust from entering, while allowing air circulation inside the drying cylinder 2. After the electrophoretic parts are dried, the air intake fan 5, the heating wire 6 and the speed-limiting motor 13 stop running, and the drive motor is restarted. The drive motor drives the pulley 16 to rotate, and the belt 18 begins to move, taking out the electrophoretic parts removed from the mesh cylinder 3.

[0031] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
