Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be described in detail in conjunction with the appended Figure 1-4 in the embodiments of the present invention. Embodiment 1

[0024] As Figure 1-4 shown, the present invention is an accurate temperature-controlled high-frequency heating device for a curing coating, including a mounting frame 1, a base 2, a platform frame 3, a uniform heating assembly 4, a high-frequency hot air blower 6 and an air pump 7.

[0025] The platform frame 3 is used to place the workpiece to be cured with a coating, and is integrally arranged on the base 2. The mounting frame 1 is also connected to the base 2 and is erected above the platform frame 3. The platform frame 3 is a conveyor belt structure, and the mounting frame 1 is in a "冂" shape. The platform frame 3 passes through the opposite openings of the mounting frame 1.

[0026] The uniform heating assembly 4 is arranged in the mounting frame 1 and above the platform frame 3. The position of the uniform heating assembly 4 is adjustable and can move back and forth. The high-frequency hot air blower 6 and the air pump 7 are both arranged on the upper surface of the mounting frame 1. The input end of the air pump 7 is connected to the high-frequency hot air blower 6, and the output end of the air pump 7 is connected to the uniform heating assembly 4.

[0027] As Figure 3 shown, the uniform heating assembly 4 includes a movable plate 41. The inner wall of the movable plate 41 is slidably connected with symmetric fixed rods 42. The movable plate 41 can slide on the outer surface of the fixed rods 42. The fixed rods 42 can play a role in supporting and guiding the movable plate 41. Both fixed rods 402 are fixedly connected to the inner wall of the mounting frame 1.

[0028] The sliding range of the movable plate 41 is limited by the fixed rods 42. And since the fixed rods 42 are fixed to the mounting frame 1, the movable plate 41 will not directly fall off during the back-and-forth sliding.

[0029] A hot air duct 43 is fixedly connected to the inner wall of the movable plate 41 , and hot air can be transported into the hot air duct 43 through a conduit. A group of hot air nozzles 44 are connected to the outer surface of the hot air duct 43 , and the hot air entering the hot air duct 43 can be discharged through the hot air nozzles 44 .

[0030] The inner wall of the movable plate 41 is slidably connected to a connecting column 45. As the connecting column 45 moves in a circular motion and slides on the inner wall of the movable plate 41, the movable plate 41 can be driven to slide back and forth. The top of the connecting column 45 is rotatably connected to a driving plate 46. As the driving plate 46 rotates, the connecting column 45 can be driven to make a circular motion.

[0031] like Figure 3 As shown, the first motor 47 is a servo motor, whose output end extends to the bottom of the mounting frame 1 and is rotatably connected to the mounting frame 1. The motor shaft of the first motor 47 is fixedly connected to the drive plate 46. By starting the first motor 47, the drive plate 46 can be driven to perform circular motion.

[0032] like Figure 2 As shown, a control panel 5 is installed on the outer surface of the installation frame 1, and a high-frequency hot air blower 6 is installed on the upper surface of the installation frame 1. The control panel 5 is electrically connected to the high-frequency hot air blower 6 through a wire. The control panel 5 and the high-frequency hot air blower 6 both belong to the prior art, and the models of the control panel 5 and the high-frequency hot air blower 6 are not further limited in this application.

[0033] The high-frequency hot air blower 6 can heat the air entering the high-frequency hot air blower 6 , and the control panel 5 can accurately control the heating power of the high-frequency hot air blower 6 , thereby controlling the heating temperature and heating rate of the air by the high-frequency hot air blower 6 .

[0034] like Figure 2 As shown, an air pump 7 is installed on the upper surface of the mounting frame 1, the input end of the air pump 7 is connected to the high-frequency hot air blower 6 through a conduit, and the output end of the air pump 7 is connected to the hot air duct 43 through a conduit. The air pump 7 belongs to the prior art, and the model of the air pump 7 is not further limited in this application.

[0035] The hot air heated by the high-frequency hot air blower 6 can be transported to the hot air duct 43 through the conduit by the air pump 7. The conduit used to connect the air pump 7 and the hot air duct 43 is a hose, and the hose passes through the side wall of the installation frame 1 and can slide inside the side wall.

[0036] like Figure 1 Figure 2 Figure 4 As shown, the platform frame 3 is a conveyor belt structure, including two support frames 31, a driven rod 32, an active rod 33, a first pulley 34, a second motor 35 and a second pulley 36.

[0037] The two support frames 31 are symmetrically fixedly connected to the upper surface of the base 2 , a group of driven rods 32 are rotatably connected between the two support frames 31 , and an active rod 33 is rotatably connected between the two support frames 31 .

[0038] The outer surfaces of the driven rod 32 and the active rod 33 are sleeved with a conveyor belt. The active rod 33 rotates, and with the auxiliary support of the driven rod 32, the conveyor belt can be driven to rotate, thereby conveying the workpiece that needs to be cured.

[0039] like Figure 4 As shown, both ends of the active rod 33 extend to the outside of the support frame 31 , and both ends of the active rod 33 are fixedly connected with a first pulley 34 , and the rotation of the first pulley 34 can drive the rotation of the active rod 33 .

[0040] A second motor 35 is mounted on the upper surface of the base 2 , and a second pulley 36 is fixedly connected to the motor shaft of the second motor 35 . The second pulley 36 is transmission-connected to the first pulley 34 via a belt.

[0041] The second motor 35 is a dual-shaft motor, which belongs to the prior art, and the motor shafts at both ends extend out of the motor housing. By starting the second motor 35, the second pulley 36 can be driven to rotate, and under the action of the belt, the first pulley 34 can be driven to rotate.

[0042] The method of using the precise temperature-controlled high-frequency heating device for curing the coating of this embodiment is as follows:

[0043] First, the coating material is placed on the conveyor belt provided on the outer surface of the driven rod 32 and the active rod 33, and then the workpiece to be cured is conveyed to the inside of the installation frame 1 by starting the second motor 35. At this time, the first motor 47, the high-frequency hot air blower 6 and the air pump 7 are started. With the start of the high-frequency hot air blower 6, high-frequency heating of the air can be achieved, and with the start of the air pump 7, the heated air can be formed into hot air and transported to the hot air duct 43. At the same time, the staff can accurately control the heating temperature and heating efficiency of the high-frequency hot air blower 6 through the control panel 5. At this time, with the start of the first motor 47, the driving plate 46 can be driven to rotate, thereby driving the connecting column 45 to move in a circle and slide on the inner wall of the movable plate 41, and on the guide of the fixed rod 42, the connecting column 45 can move in a circle and slide on the inner wall of the movable plate 41. Under the supporting action, the movable plate 41 can be driven to swing back and forth, and then the hot air duct 43 can be driven to swing back and forth along with the movable plate 41. Under the action of the wind ejected by the hot air nozzle 44, the insulating powder coating on the surface of the workpiece below can be evenly heated, thereby effectively avoiding the situation where uniform heating cannot be performed due to the fixed design of the hot air duct 403. It not only further guarantees the heating and curing rate of the insulating powder coating, but also avoids the situation where the quality of the workpiece is reduced due to the uneven curing of the insulating powder coating on the outer surface of the workpiece. After the heating and curing of the insulating powder coating is completed, the second motor 35 is started again, and the heated and cured workpiece can be conveyed to the next step for processing under the action of the conveyor belt, thereby improving the overall efficiency.

[0044] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
