Abstract
Description
Technical Field
[0001] This invention relates to the field of coating roller coating and waxing technology, specifically to a condensation prevention and rinsing device for waxing machines. Background Technology
[0002] During the waxing process of aluminum sheet and strip tank body and lid material roller coating, the wax liquid in the waxing machine needs to be maintained at 85℃. Since the melting temperature of wax liquid is 65℃, when the water temperature is too low, or when production stops, the residual wax liquid in the pipes will clog the pipes. During production, a heating cable is needed to heat the pipes to 90℃ to melt the wax liquid in the pipes and clear the blockage before production can resume. If the blockage is severe, the pipes need to be disassembled and cleaned. If no measures are taken, the pipe return will be obstructed. In winter, when the ambient temperature is below 3℃, the temperature inside the wax tray is low, and small particles will condense on the surface of the wax liquid, resulting in small particles on the coated sheet and leading to defective products. Therefore, rapidly heating the wax liquid before waxing, ensuring the pipes are secure, and reducing energy consumption are new requirements for the wax liquid circulation system of current waxing machines. Summary of the Invention
[0003] This invention addresses the shortcomings of existing technologies by providing a condensation-preventing flushing device for waxing machines. This effectively solves the problem that in existing technologies, it is difficult to unclog pipes after the wax melts inside, and in cases of severe blockage, the pipes need to be dismantled for cleaning.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: The anti-condensation rinsing device for the waxing machine includes a wax tray, which has a hot water circulation system and a wax liquid circulation system, and is equipped with a level gauge for level protection; the wax tray is connected to a supply pipe and a return pipe, and both the supply pipe and the return pipe are connected to a wax storage tank.
[0005] Furthermore, a first hand valve and a fourth hand valve are provided on both sides of the supply pipe, a first flexible hose connected to the wax plate is provided at one end of the supply pipe, a wax pump and a third hand valve are provided on both sides of the return pipe, a second flexible hose connected to the wax plate is provided at one end of the return pipe, and a second hand valve is provided on the connecting pipe between the return pipe and the supply pipe.
[0006] Furthermore, the wax storage tank is equipped with a thermometer and a stirrer. The wax storage tank is also equipped with a wax return pipe interface connected to the beginning of the return pipe, a wax supply pipe interface connected to the wax supply pump, a hot water supply interface and a hot water return interface. The hot water supply interface is connected to a second hot water circulation inlet, and the hot water return interface is connected to a second hot water circulation outlet.
[0007] Furthermore, the hot water circulation system includes a hot water inlet pipe and a hot water outlet pipe, the hot water inlet pipe being connected to a first circulating hot water inlet, and the hot water outlet pipe being connected to a first circulating hot water outlet.
[0008] Furthermore, the wax circulation system includes a wax supply pipe and a wax return pipe, wherein the wax supply pipe is connected to a first hose and the wax return pipe is connected to a second hose.
[0009] Furthermore, both the wax tray and the wax storage tank are equipped with heat exchangers.
[0010] This invention features a novel structure, ingenious design, and simple and convenient operation, offering the following advantages compared to existing technologies: By manually flushing the wax supply and return pipes, all condensate is flushed out, reducing the waiting time for production. This eliminates the need for heating and insulation of the pipes with heat tracing tape, saving electricity and reducing the workload of workers. Ensuring smooth return flow in the pipes keeps the wax temperature within a reasonable range, providing better assurance for the quality of the strip. Attached Figure Description

[0012] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0013] Anti-condensation rinsing device for waxing machine, such as Figure 1-3 As shown, it includes a wax tray 1, which includes a hot water circulation system and a wax liquid circulation system, and is equipped with a level gauge 18 for level protection; the wax tray 1 is connected to a supply pipe 27 and a return pipe 28, and both the supply pipe 27 and the return pipe 28 are connected to a wax storage tank 3.
[0014] like Figure 1 As shown, a first hand valve 9 and a fourth hand valve 10 are provided on both sides of the supply pipe 27. A first flexible hose 25 connected to the wax plate 1 is provided at one end of the supply pipe 27. A wax pump 12 and a third hand valve 11 are provided on both sides of the return pipe 28. A second flexible hose 26 connected to the wax plate 1 is provided at one end of the return pipe 28. A second hand valve 13 is provided on the connecting pipe between the return pipe 28 and the supply pipe 27.
[0015] like Figure 1 and 3 As shown, the wax storage tank 3 is equipped with a thermometer 21 and a stirrer 19. The wax storage tank 3 is equipped with a wax liquid return pipe interface 2 connected to the first end of the return pipe 28. The wax storage tank 3 is also equipped with a wax liquid supply pipe interface 23 connected to the wax supply pump 12. The wax storage tank 3 is also equipped with a hot water supply interface 20 and a hot water return interface 22. The hot water supply interface 20 is connected to a second hot water circulation inlet 7, and the hot water return interface is connected to a second hot water circulation outlet 6.
[0016] like Figure 1 and 2 As shown, the hot water circulation system includes a hot water inlet pipe 14 and a hot water outlet pipe 15. The hot water inlet pipe 14 is connected to a first circulating hot water inlet 5, and the hot water outlet pipe 15 is connected to a first circulating hot water outlet 4.
[0017] like Figure 1 and 2 As shown, the wax circulation system includes a wax supply pipe 16 and a wax return pipe 17. The wax supply pipe 16 is connected to the first hose 25, and the wax return pipe 17 is connected to the second hose 26.
[0018] like Figure 1 As shown, both the wax tray 1 and the wax storage tank 3 are equipped with heat exchangers 8.
[0019] The heat exchanger helps to ensure uniform heating within the wax tray 1 and the wax storage tank 3.
[0020] The wax tray 1 is equipped with a hot water circulation system consisting of a hot water inlet pipe 14 and a hot water outlet pipe 15 to ensure that the wax tray 1 has a certain temperature during the production process. Since the material tray is small and cannot meet the wax liquid production temperature of 85℃, the wax liquid needs to be circulated to the wax storage tank 3, which is continuously heated. The wax liquid circulation system consisting of the wax liquid supply pipe and the wax liquid return pipe 17 ensures that the wax liquid temperature is at the working temperature required by the process. In addition, it prevents the wax liquid from condensing and precipitating into particles in the wax tray 1 due to long-term inactivity, which would lead to unqualified production quality. The level gauge 18 will alarm when the first hose 25 is detached or the valve is opened incorrectly, and there is no wax liquid in the material tray. This can prompt the operator to check the equipment and reduce unnecessary waste production.
[0021] The supply pipe 27 and return pipe 28 consist of a wax pump 12, a first hose 25, a second hose 26, a first hand valve 9, a second hand valve 13, a third hand valve 11, and a fourth hand valve 10. Because parts of the first hose 25 and the second hose 26 droop downwards, their height is lower than that of the first hand valve 9, second hand valve 13, third hand valve 11, and fourth hand valve 10, the wax in the pipes cannot return to the wax storage tank 3 after production, causing blockages every time the machine is started. The previous solution was to use a heated hose with a heating cable to maintain the temperature at 90℃. This method is costly in terms of equipment and energy consumption; the hose alone costs 12,000 yuan per meter, and the temperature controller costs 8,000 yuan. Therefore, this solution melts the wax in the wax storage tank 3 to 85℃, and then the valve group switches between different modes. Simultaneously, the wax pump 12 flushes out the solidified wax in each branch pipe to ensure unobstructed flow.
[0022] The wax storage tank 3 consists of a hot water supply interface 20 and a hot water return interface 22. The hot water supply interface 20 is connected to a second circulating hot water inlet 7, and the hot water return interface 22 is connected to a second circulating hot water outlet 6. The hot water circulation system of the wax storage tank 3 ensures that the wax liquid maintains a working temperature of 85℃. The wax storage tank 3 is equipped with a temperature sensor, which informs the operator whether the wax liquid has melted to the working temperature. After the wax liquid melts to 65℃, the stirrer 19 is turned on to ensure that the melting temperature of the wax liquid in the wax storage tank 3 is uniform. After the wax temperature reaches 85℃, the wax liquid returns to the pipe interface 2. The wax supply pipe interface 23 is connected to the supply and return pipes, and its functions are: 1. to flush the pipes; 2. to circulate the wax liquid and maintain the wax liquid temperature.
[0023] The working process of this invention is as follows: First, solid wax is placed from the wax barrel into the wax storage tank 3. The wax storage tank 3, through its own hot water supply interface 20 and hot water return interface 22, forms a hot water circulation system to heat the wax liquid to 85°C. When the temperature reaches 65°C, the stirrer 19 is turned on to ensure that the wax liquid melts evenly in the wax storage tank 3. The wax storage tank 3 is equipped with a thermocouple, which is electrically connected to an HMI. The operator checks the thermocouple temperature through the HMI and checks that the heating is complete. Then, the following operations are performed: The operator first closes the first hand valve 9, the second hand valve 13, and the fourth hand valve 10, and opens the third hand valve. Then, the wax supply pump 12 is started and the speed of the wax supply pump 12 is set to 15%. After observing that liquid wax flows out of the wax tray 1, the wax supply pump 12 is turned off. Then close the first hand valve 9 and the third hand valve 11, open the second hand valve 13 and the fourth hand valve 10, start the wax supply pump 12, set the speed of the wax supply pump 12 to 15%, and after observing that liquid wax flows out of the return pipe of the wax storage tank 3, close the wax supply pump 12. Then close the third hand valve 11 and the fourth hand valve 10, open the first hand valve 9 and the second hand valve 13, start the wax supply pump 12, set the speed of the wax supply pump 12 to 15%, and after observing that liquid wax flows out of the wax tray 1, turn off the wax supply pump 12. Finally, open the third hand valve 11, the first hand valve 9, and the fourth hand valve 10, close the second hand valve 13, start the wax supply pump 12, set the speed of the wax supply pump 12 to 25%, and observe that liquid wax flows out of the return pipe of the wax storage tank 3. The operation is complete. After the rinsing process is completed, the wax liquid is pumped into the wax tray 1 through the wax liquid circulation system consisting of the wax liquid supply pipe and the wax liquid return pipe 17. The liquid level in the wax tray 1 reaches the requirements of the level gauge 18 (the liquid level is displayed in green on the HMI). The hot water circulation system consisting of the hot water inlet pipe 14 and the hot water outlet pipe 15 ensures that the temperature of the tray is higher than the room temperature.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
