[0021] As Figure 1 shown, a curing furnace provided by the present invention includes a furnace body 1. The furnace body is an existing structure and can cure workpieces.

[0022] Two sliding grooves 1.1 are provided in the furnace body 1. The two sliding grooves 1.1 are arranged oppositely. A sliding plate 1.2 is slidably connected in each sliding groove 1.1. A rotating plate 2 is rotatably connected between the two sliding plates 1.2. The rotating plate 2 is a circular plate. An annular groove 2.1 is provided on the side surface of the rotating plate 2. The cross-section of the annular groove 2.1 is convex. Two guiding blocks 2.2 are slidably connected in the annular groove 2.1. Each guiding block 2.2 is connected to the corresponding sliding plate 1.2, so that the rotating plate 2 can rotate while moving forward and backward.

[0023] As Figure 3 shown, a driving device 10 is connected to one side of the furnace body 1. The driving device 10 drives the rotating plate 2 to move forward and backward. The driving device 10 is a second motor. The second motor is connected to the side surface of the furnace body 1. A through hole is provided on the side surface of the furnace body 1. The output shaft of the second motor passes through the through hole. A first gear 11 is connected to the output shaft of the second motor. A rack 1.3 is connected to the lower side of one of the sliding plates 1.2. The rack 1.3 meshes with the first gear 11. The first gear 11 is driven by the second motor to rotate. The first gear 11 meshes and drives the rack 1.3, so that the rack 1.3 slides in the sliding groove 1.1, thereby driving the rotating plate 2 to move forward and backward.

[0024] A fixed shaft 8 is connected to the upper side of the rotating plate 2. In this embodiment, the fixed shaft 8 is an elastic telescopic shaft, which is a conventional structure. The elastic telescopic shaft includes a main shaft body. A square groove is provided on the upper end surface of the main shaft body. A spring is connected to the bottom of the rectangular groove, and a square shaft is connected to the upper end of the spring, so that the fixed shaft 8 can drive the rotating plate 2 to rotate while telescoping.

[0025] A bracket 5 is connected to the upper side of the furnace body 1, and a driving member 6 is connected to the bracket 5. In this embodiment, the driving member 6 is an oil cylinder. A first motor 7 is connected to the driving rod of the driving member 6. A through hole is provided at the top of the furnace body 1, and the output shaft of the first motor 7 passes through the through hole. The first motor 7 is drivingly connected to the fixed shaft 8 through a clamping member 9, as Figure 2 shown. The clamping member 9 includes a clamping block 9.1, which is connected to the output shaft of the first motor 7. The clamping block 9.1 is clamped to a fixing plate 9.2 with a clamping groove. The fixing plate is connected to the upper end of the square shaft. That is, the driving member 6 drives the first motor 7 to move downward, and the output shaft of the first motor 7 drives the clamping block 9.1 to move downward. When the clamping block 9.1 is clamped to the fixing plate 9.2, the first motor 7 can drive the rotating plate 2 to rotate.

[0026] Only when the driving member 6 drives the clamping block 9.1 to move upward and the clamping block 9.1 is disengaged from the clamping groove can the driving device 10 be started to drive the rotating plate 2 to move back and forth.

[0027] As Figure 4 shown, a group of bearing seats are evenly distributed on the circumference of the lower side of the rotating plate 2. A rotating rod 3 is inserted and rotatably connected in each bearing seat. A hook 4 is connected to the lower side of each rotating rod 3. The rotation of the rotating plate 2 drives the revolution of the hook 4. The first motor 7 is drivingly connected to the fixed shaft 8 through the clamping member 9, and the fixed shaft 8 drives all the rotating rods 3 to rotate through a transmission mechanism. The transmission mechanism includes a first transmission mechanism and a second transmission mechanism. The first transmission mechanism adopts a traditional planetary gear mechanism, including a driving gear 2.5, which is connected to a rotating shaft 2.6. A bearing seat is sleeved outside the rotating shaft 2.6, and the bearing seat is connected to the lower side of the rotating plate 2, so that the rotating shaft 2.6 can rotate. A driven gear 3.1 is connected to each rotating rod 3, and the driven gear 3.1 meshes with the driving gear 2.5. The driving gear 2.5 is driven to rotate by the rotating shaft 2.6, and the driving gear 2.5 meshes and drives all the driven gears 3.1, so as to drive all the rotating rods 3 to rotate, and then drive the hook 4 to rotate.

[0028] The second transmission mechanism includes a driving wheel 2.7 coaxially connected to the main shaft body of the fixed shaft 5. The driving wheel 2.7 drives a first driven wheel 2.9 through a first transmission belt 2.8. The first driven wheel 2.9 is connected to a second driven wheel 211 through a vertical shaft 210. The vertical shaft 210 is rotatably connected to the rotating plate 2, that is, a mounting hole is provided on the rotating plate 2, a bearing is installed in the mounting hole, and the vertical shaft 210 is inserted into the bearing. The second driven wheel 211 drives a third driven wheel 213 through a second transmission belt 212. The third driven wheel 213 is coaxially connected to the rotating shaft 2.6, that is, while driving the hook 4 to revolve by the first motor 7, it can also rotate itself.

[0029] After the workpiece is cured, start the driving member 6 to drive the first motor 7 to move upward, so that the clamping block 9.1 is disengaged from the clamping groove. Then start the driving device 10 to drive the rotating plate 2 to move towards the furnace door. Then the employee takes the cured workpiece and then feeds the workpiece to be cured. After feeding, start the driving device 10 to drive the rotating plate 2 to move into the furnace body 1. When the rotating plate 2 returns to its original position, start the driving member 6 to drive the first motor 7 to move downward, so that the clamping block 9.1 is clamped into the clamping groove, so that the first motor 7 can drive the rotating plate 2 to rotate. While the rotating plate 2 rotates, it can drive all the rotating rods 3 to rotate, realizing the revolution and self-rotation of the workpiece at the same time. Therefore, when loading or unloading the workpiece, this device can drive the workpiece to move to the furnace door through the second driving device 10, which is convenient for the employee to load or unload the workpiece and saves the employee from entering the furnace body.
