DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: See Figures 1 to 4 , an electrophoretic paint drying device, comprising: a processing table 1, on which is mounted a steering assembly for adjusting the position of a workpiece; a drying mechanism 2, mounted on the processing table 1, for drying the electrophoretic paint on the workpiece; a lifting mechanism 3, mounted on the steering assembly, for driving the workpiece to rise and fall; a hooking mechanism 4, mounted at the lower end of the lifting mechanism 3, for hooking the workpiece; a socket is provided at the upper end of a box cover 22 of the drying mechanism 2, a sealing groove 221 is provided at a position corresponding to the socket at the upper end of the box cover 22, and a sealing ring 222 is mounted at a position corresponding to the sealing groove 221 at the lower end of a lifting seat 34 of the lifting mechanism 3.

[0023] The working principle of the present invention is as follows: when in use, the workpiece is hooked on the hooking mechanism 4, and then the workpiece is driven to rotate through the steering assembly so that it is transferred to the top of the drying mechanism 2. Then, the lifting mechanism 3 drives the workpiece downward. At the same time, the sealing ring 222 at the lower end of the lifting seat 34 is inserted into the sealing groove 221 at the upper end of the box cover 22, thereby sealing the drying mechanism 2, which can effectively reduce the loss of heat during drying, thereby reducing energy consumption and further reducing drying costs, thereby better meeting usage requirements.

[0024] As a further solution, the steering assembly includes a steering sleeve 12 installed on the processing table 1, a steering column 13 is rotatably installed in the steering sleeve 12, a steering beam 14 is installed on the upper end of the steering column 13, and a steering motor 11 is also installed at the lower end of the processing table 1, and the output end of the steering motor 11 is drivingly connected to the shaft end of the steering column 13.

[0025] The working principle of the steering assembly is: when steering, start the steering motor 11, and the steering column 13 is driven to rotate by the steering motor 11, thereby driving the steering beam 14 to rotate, and then the workpiece can be transferred to the top of the drying mechanism 2, making it convenient to subsequently transfer the workpiece to the drying mechanism 2 for drying processing.

[0026] As a further solution, the drying mechanism 2 includes a drying box 21 installed on the processing table 1, and a box cover 22 is installed on the upper end of the drying box 21. Multiple groups of electric heating tubes 23 are distributed and installed in the drying box 21. A pressure relief valve 24 is also installed on the upper end of the box cover 22. By setting the pressure relief valve 24, pressure relief can be performed to improve the safety of drying. A temperature sensor 26 is also installed on the upper end of the box cover 22, and a controller 25 is also installed on the drying box 21. The temperature sensor 26 and the electric heating tube 23 are all connected to the controller 25.

[0027] The working principle of the drying mechanism 2 is: during specific use, the temperature threshold in the drying box 21 is set through the controller 25. When the temperature in the drying box 21 is lower than the set temperature threshold, the power of the electric heating tube 23 is increased; when the temperature in the drying box 21 is higher than the set temperature threshold, the power of the electric heating tube 23 is reduced.

[0028] As a further solution, the lifting mechanism 3 includes a lifting electric cylinder 31 installed at the upper end of the steering beam 14. The telescopic end of the lifting electric cylinder 31 passes through the steering beam 14 and is fixed with a lifting seat 34. A lifting guide rod 32 is also slidably inserted on the steering beam 14, and the lower end of the lifting guide rod 32 is fixedly connected to the upper end of the lifting seat 34.

[0029] The working principle of the lifting mechanism 3 is: the lifting electric cylinder 31 pushes the lifting seat 34 downward, so that the lifting seat 34 seals the socket on the box cover 22. At this time, the workpiece is inserted into the drying box 21, and the sealing ring 222 is inserted into the sealing groove 221, which can improve the sealing effect and effectively reduce the loss of heat during drying.

[0030] As a further solution, the hooking mechanism 4 includes a hooking shaft 41 rotatably mounted at the lower end of the lifting seat 34, a hooking plate 43 is mounted at the lower end of the hooking shaft 41, and a number of hooks 42 are distributed and mounted at the lower end of the hooking plate 43. A hooking gear ring 44 is also mounted on the hooking shaft 41, and a hooking gear 45 is also mounted at the lower end of the lifting seat 34. The hooking gear 45 is meshed and connected with the hooking gear ring 44. A hooking motor 46 is also mounted at the upper end of the lifting seat 34, and the output end of the hooking motor 46 is drivingly connected to the shaft end of the hooking gear 45.

[0031] The working principle of the hooking mechanism 4 is as follows: when in use, the workpiece is hooked on the hook 42 to transfer the workpiece to the drying box 21. During drying, the hooking motor 46 is started, and the hooking motor 46 drives the hooking gear 45 to rotate, thereby driving the hooking gear ring 44 to rotate, and then realizing the rotation of the hooking plate 43, and then the workpiece rotates around the hooking shaft 41, so that the workpiece is heated more evenly and the drying effect is improved.

[0032] In order to prevent the hooking motor 46 from being squeezed when the lifting seat 34 rises, a limiting column 33 is further installed on the upper end of the lifting seat 34.
