Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a rapid drying workbench for spray-coated workpieces. Background Technology

[0002] During the forging process, it is often necessary to spray a specific type of coating on the surface of the workpiece to facilitate subsequent forming processes. For example, before extruding certain metal sheets, a graphite layer is sprayed on their surface to improve surface lubrication. In order to accelerate the curing and forming of the coating, a drying device is needed to heat and dry the sprayed workpiece.

[0003] According to the search results, the announcement number CN216396955U, entitled "A rapid drying device for spraying, including a drying drum box," reveals that although the device has advantages such as improving the uniformity and efficiency of drying and ensuring the quality of dried objects, it also has the following disadvantages to some extent.

[0004] For example, because the device has a flat worktable, the workpiece can only be heated and dried from four sides. The side of the workpiece away from drying cannot be heated, which requires the workpiece to be flipped over and processed again. Repeated heating and drying of the workpiece's four sides can also damage the workpiece, thereby affecting processing efficiency and subsequent molding processes. In addition, the heat generated during the drying process of the parts is directly emitted into the atmosphere, resulting in a waste of resources. In order to solve the above technical problems, it is necessary to design a rapid drying worktable for sprayed workpieces. Utility Model Content

A breathable mesh plate 13 is embedded in the surface of the mounting base 10. A temperature and humidity sensor 14 is fixedly installed in the inner cavity of the housing 1.

[0021] Please see Figure 4The conveying fan 11 is fixedly installed in the inner cavity of the mounting base 10, and the heating wire 4 is fixedly installed in the inner cavity of the breathable mesh plate 13. By setting the conveying fan 11, gas is conveyed to achieve ventilation or gas circulation.

[0022] Please see Figure 2 A bearing is provided at the connection between the shaft of the drive motor 7 and the inner wall of the housing 1. The outer ring of the bearing is fixedly connected to the inner wall of the housing 1, and the inner ring of the bearing is sleeved on the surface of the shaft of the drive motor 7. By setting the bearing, the shaft of the rotating body drive motor 7 is supported, reducing friction and wear with the housing 1 during the movement, and ensuring the smooth rotation of the shaft of the drive motor 7.

[0023] Please refer to the figure. Figure 3 and Figure 4 The top of the exhaust pipe 9 is connected to the ventilation pipe 15, and one side of the ventilation pipe 15 is connected to the air inlet pipe 16. The top of the ventilated plate 5 is welded with a baffle 17 and a fixing plate 18 respectively. A screw 19 is installed through one side of the fixing plate 18. One end of the screw 19 is rotatably connected to a clamping block 20. A rubber pad 21 is fixedly installed on the opposite side of the baffle 17 and the clamping block 20. By setting the fixing plate 18, the screw 19 and the ventilated plate 5 component materials are firmly connected together to ensure the stability of the screw 19 structure.

[0024] Please see Figure 3 The screw 19 is threaded to the inner wall of the fixing plate 18, and a handle is fixedly connected to the surface of the screw 19. By setting the handle, a stable and comfortable grip is provided to ensure that the user can accurately and powerfully operate the relevant tool screw 19.

The surface of the exhaust pipe 9 is connected to the exhaust valve 23. By setting the handle, it is convenient for users to manually open or close the box door 22, providing an intuitive and convenient operation method.

[0026] In use, open the chamber door 22 and place the workpiece on the ventilated plate 5 of the drying workbench. The user then manually rotates the handle according to the workpiece size, causing the screw 19 to rotate and the clamping block 20 to move left and right. Adjust the distance between the baffle 17 and the clamping block 20 to a position suitable for the workpiece. The workpiece is then clamped between two rubber pads 21, providing anti-wear protection. The rubber pads 21 contact the workpiece, protecting it. The heating wire 4, located inside the ventilated mesh plate 13, heats the air. The blower 3 blows external air into the chamber 1 along the air inlet pipe 16, mixing with the heated air through the ventilated mesh plate 13 to form a hot airflow. The hot air exchanges heat with the workpiece surface within the chamber 1 and may be guided through the exhaust pipe 9.

Start the conveyor fan 11, and hot air is discharged from the chamber 1 through the exhaust pipe 9. Additional ventilation is provided through the ventilation pipe 15 and the exhaust pipe 12. The exhaust pipe 12 causes hot air to be discharged from the permeable mesh plate 13 through the mounting base 10. The ventilation pipe 15 causes the hot air to recirculate and enter the chamber 1 from the permeable mesh frame 2. Start the drive motor 7 to drive the electric telescopic rod 8 to rotate, so that the contact surface between the permeable plate 5 and the residual heat of the workpiece is fully in contact. Start the electric telescopic rod 8 to extend and retract, so that the surface contact heat is suitable for coating quality. Through the multi-directional hot air circulation system of the conveyor fan 11 and the blower 3, the hot air can be blown evenly to different surfaces of the workpiece. The temperature and humidity sensor 14 is used to monitor the environmental conditions inside the chamber 1 to ensure that the drying process is carried out under appropriate conditions. According to the feedback of the sensor, it may be necessary to adjust the output of the heating wire 4, the speed of the blower 3 and the conveyor fan 11. If the chamber 1 is overheated, start the exhaust system of the exhaust pipe 9. The exhaust valve 23 should be able to effectively discharge the hot air.

[0027] In summary, this rapid drying workbench for sprayed workpieces, through the cooperation of the housing 1, the ventilated mesh frame 2, the blower 3, the heating wire 4, the ventilated plate 5, and the adjustment mechanism 6, solves the problems of incomplete drying of workpieces and the lack of flexibility in the design of drying equipment, which often limits its application range due to the inability to adapt to the shape of different workpieces.
