[0024] Working principle: Since the main reflection position of the production device is the middle and lower part of the inner cavity of the kettle body 1, the cleaning of the inner cavity of the kettle body 1 is also mainly concentrated on the centralized cleaning of the middle and lower part of the inner cavity of the kettle body 1. First, unscrew the limit nut at the bottom of the outer periphery of the rotating rod 3, and then open the inspection door 15 to remove the stirring paddle 10 by loosening the screws fixed between the stirring paddle 10 and the rotating rod 3. Then, screw the limit nut on the bottom of the outer periphery of the rotating rod 3 again, and drive the lifting device 4 to perform up and down cleaning work through the forward and reverse rotation of the servo motor 2. The purpose of the limit nut is to limit the up and down movement of the lifting device 4. The production device is provided with a screw rod 5 on the outer wall of the rotating rod 3, and at the same time, A matching screw sleeve 6 is arranged on the periphery of the rod 5. An external thread is arranged on the periphery of the screw sleeve 6, and a thread groove matching the external thread on the periphery of the screw sleeve 6 is arranged on the inner ring 71 of the bearing 7. The screw sleeve 6 and the inner ring 71 are movably tightened and fixedly connected through the matching external threads and thread grooves. Two groups of connecting rods 8 are welded on the outer ring 72 of the bearing 7. The other ends of the two groups of connecting rods 8 are connected to mounting plates, and the other ends of the mounting plates are connected to cleaning sponges 9. The matching work between the screw 5 and the screw sleeve 6 enables the screw sleeve 6 to drive the bearing 7 to smoothly lift and move up and down, thereby indirectly driving the two groups of connecting rods 8 and the cleaning sponge 9 to move up and down. Since the screw sleeve 6 can be smoothly moved on the screw 5, the Therefore, once the servo motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the screw rod 5 to rotate. During the rotation of the screw rod 5, the screw rod sleeve 6 will drive the bearing 7 to move up and down smoothly due to the centripetal force of the rotation of the screw rod 5. The bearing 7 then drives the two sets of connecting rods 8 and the cleaning sponge 9 to clean the inner cavity of the kettle body 1 up and down. In order to ensure that the up and down movement of the cleaning sponge 9 is controllable and the servo motor does not rotate quickly, thereby damaging the kettle body 1 and the cleaning device, a lifting device 4 must be provided to perform necessary limiting functions. The lifting device 4 uses two sets of rod bodies 42 as a base to fix the two sets of A spring 45 is welded between the telescopic mother rod 43, the telescopic mother rod 43 and the telescopic sub-rod 44 to limit the up and down movement of the connecting rod 8, so that the screw sleeve 6 drives the bearing 7 and the connecting rod 8 and the cleaning sponge 9 to achieve the function of slow rising and falling, so as to avoid the rapid cleaning movement driven by the servo motor 2, causing damage to the kettle body 1 and the cleaning sponge 9 and the connecting rod 8, and bring unnecessary losses. The production device can not only clean the inner cavity of the kettle body 1, but also realize the slow rising and falling of the cleaning device through the lifting device 4. After completing the cleaning work of the inner cavity of the kettle body 1, the heating plate 14 accelerates the rapid drying of the moisture in the inner cavity of the kettle body 1 after cleaning.
