Description

Technical Field

[0001] This utility model relates to the field of electrophoretic workpiece drying equipment, specifically a fully uniform drying line for electrophoretic workpieces. Background Technology

[0002] Electrophoretic coatings require proper drying and curing to achieve ideal properties. Insufficient drying reduces adhesion, hardness, corrosion resistance, and stone chip resistance; excessive drying can lead to brittleness, cracking, or even peeling. Therefore, improving the uniformity of heat drying on the workpiece surface is crucial. However, existing electrophoretic workpiece drying lines use hot air flow for drying, but the airflow is unidirectional, and the workpieces cannot effectively rotate inside the drying chamber, resulting in incomplete and uneven drying. Therefore, this paper proposes a fully uniform drying line for electrophoretic workpieces to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a fully uniform drying line for electrophoretic workpieces in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a fully uniform drying line for electrophoretic workpieces, comprising a drying chamber, a hot air blower, an arc-shaped long plate, U-shaped tubes, a workpiece hoisting guide rail, a hydraulic cylinder, a strip-shaped toothed block, a fan-shaped plate, and a gear. Multiple U-shaped tubes are arranged from front to back inside the drying chamber, and the same workpiece hoisting guide rail passes through the multiple U-shaped tubes. An arc-shaped long plate is installed at the edge of the fan-shaped plate at the top of each U-shaped tube on both sides, and a short pipe is connected and installed in the middle of each U-shaped tube. Hot air nozzles are distributed on both sides of each U-shaped tube, and the hot air nozzles face the interior of the arc-shaped long plate. One end of the short pipe is rotatably connected to the hole structure at the bottom of the cylinder through a bearing, and the gear located in the middle of the short pipe meshes with the tooth surface of the strip-shaped toothed block.

[0005] In a further technical solution, the length of the two sides of the U-shaped tube is less than the length of the arc-shaped long plate.

[0006] In a further technical solution, the opening of the cylinder is connected to a hot air outlet pipe located at the top of the drying chamber, and one end of the hot air outlet pipe is installed on the output port of the heat blower.

[0007] In a further technical solution, both ends of the strip-shaped toothed block are connected to the outputs of two hydraulic cylinders via connectors, and the cylinder body is fixedly connected to the internal sidewall of the drying chamber.

[0008] A further technical solution is that the arc-shaped long plate forms a uniform diffusion of hot gas ejected from the hot gas nozzle between itself and another arc-shaped long plate in the same group.

[0009] Compared with the prior art, the advantages of this utility model are as follows: the uniform diffusion of hot air ejected from the hot air nozzle is formed between the arc-shaped long plate and another arc-shaped long plate in the same group, which improves the uniformity of the workpiece surface being heated and dried; the coordinated extension and retraction of the front and rear distributed oil cylinders push and pull the connected strip tooth blocks, which can drive all the meshed gears to rotate, and at the same time drive all the connected U-shaped tubes to rotate within a 120° range, and can reciprocate, which is conducive to adjusting the direction of hot air outlet and improving the fullness of workpiece drying.

[0016] Please see Figure 1-3 As shown, a fully uniform drying line for electrophoretic workpieces includes a drying chamber 1, a hot air blower 2, an arc-shaped long plate 4, a U-shaped tube 5, a workpiece hoisting guide rail 6, a hydraulic cylinder 7, a strip-shaped toothed block 8, a fan-shaped plate 10, and a gear 12. Multiple U-shaped tubes 5 are arranged from front to back inside the drying chamber 1, and the same workpiece hoisting guide rail 6 passes through the multiple U-shaped tubes 5. An arc-shaped long plate 4 is installed at the edge of the fan-shaped plate 10 on both sides of each U-shaped tube 5, and a short pipe 11 is connected and installed in the middle of each U-shaped tube 5. Hot air nozzles 510 are distributed on both sides of each U-shaped tube 5, and the hot air nozzles 510 face the interior of the arc-shaped long plate 4. One end of the short pipe 11 is rotatably connected to the hole structure at the bottom of the cylinder 9 through a bearing, and the gear 12 located in the middle of the short pipe 11 meshes with the tooth surface of the strip-shaped toothed block 8.

[0017] The length of the tubes on both sides of the U-shaped tube 5 is less than the length of the arc-shaped long plate 4. The arc-shaped long plate 4 and another arc-shaped long plate 4 in the same group form a uniform diffusion of the hot gas ejected from the hot gas nozzle 510.

[0018] The opening of the cylinder 9 is connected to the hot air outlet pipe 3 located at the top of the drying chamber 1, and one end of the hot air outlet pipe 3 is installed on the output port of the heat blower 2.

[0019] Both ends of the strip-shaped toothed block 8 are connected to the outputs of the two oil cylinders 7 respectively through connectors, and the cylinder body of the oil cylinder 7 is fixedly connected to the inner side wall of the drying chamber 1.

[0020] The specific drying process is as follows: the workpieces are hung on the transport hooks on the workpiece hoisting guide rail 6 and enter the drying chamber 1 in sequence. The workpieces pass through the U-shaped tube 5. The hot air output from the heat blower 2 enters each cylinder 9 through the hot air outlet pipe 3 until it is sprayed out from the U-shaped tube 5 connected to the cylinder 9 and the short pipe 11 and from the hot air nozzle 510. Since the hot air nozzle 510 is oriented towards the inside of the arc-shaped long plate 4, the hot air diffuses in the opposite direction to dry the workpiece located in the middle of the U-shaped tube 5. The difference compared to existing technologies is: 1. The uniform diffusion of hot air ejected from the hot air nozzle 510 is formed between the arc-shaped long plate 4 and another arc-shaped long plate 4 in the same group, which improves the uniformity of the workpiece surface being heated and dried. 2. By having the front and rear distributed hydraulic cylinders in a coordinated telescopic state to push and pull the connected strip-shaped toothed blocks 8, all the meshing gears 12 can be driven to rotate, and at the same time all the connected U-shaped tubes 5 can rotate within a 120° range and can reciprocate, which is beneficial to adjust the direction of hot air output and improve the fullness of workpiece drying.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
