[0002] In the blown film machine industry, heating equipment is one of the core components, and its performance directly affects the quality and production efficiency of the blown film. Traditional blown film machine heating equipment mostly uses a single electric heating element for direct heating. While this method is simple and direct, it suffers from significant problems such as high energy consumption, low thermal efficiency, and inaccurate temperature control. Especially in large-scale production, long-term high energy consumption not only increases production costs but also places a significant burden on the environment. In addition, traditional heating equipment is prone to localized overheating during the heating process, leading to uneven heating of the film material and affecting product quality. Utility Model Content

Electric heating blocks are fixedly connected to the top and bottom of one end of the heating penetration. Water tanks are provided on the inner walls of the top and bottom of the heating penetrations of the outer protective box. The two water tanks are interconnected by pipes. Heat-conducting plates are embedded and fixedly connected to the end of each water tank near the electric heating blocks. The two heat-conducting plates are in contact with the top and bottom of the electric heating blocks that are matched in position. Mounting grooves are provided on the top and bottom of the end of the heating penetration away from the electric heating blocks. Multiple circulating heating pipes are uniformly fixedly connected to the inner walls of the two mounting grooves.

[0005] Optionally, the plurality of circulating heating tubes are interconnected, and the two ends of the plurality of circulating heating tubes are respectively connected to a water tank in a matching position.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. This invention utilizes a heat-conducting plate within the water tank to effectively transfer the heat generated by the heating element to the water. The heat is then transferred to the other end of the heating inlet via a circulating heating pipe, achieving heat recycling and significantly improving thermal efficiency while reducing energy consumption. The controller precisely adjusts the heating power of the heating element according to actual needs, while an electronic level gauge monitors the water level in the tank to ensure the stability and safety of the heating process. Furthermore, the circulating heating pipe design results in more uniform heat distribution, contributing to more precise temperature control.

[0020] Please see Figure 2 , Figure 3 and Figure 4 Heating blocks 11 are fixedly connected to the top and bottom of one end of the heating through-hole 2. Water tanks 9 are provided on the inner walls of the outer protective box 1 at the top and bottom of the heating through-hole 2. The two water tanks 9 are interconnected by pipes. A heat-conducting plate 12 is embedded and fixedly connected to the end of each water tank 9 near the heating block 11. Both heat-conducting plates 12 are in contact with the top and bottom of the corresponding heating blocks 11. Mounting grooves 13 are provided on the top and bottom of the end of the heating through-hole 2 away from the heating block 11. Multiple circulating heating pipes 14 are evenly fixedly connected to the inner walls of the two mounting grooves 13. The multiple circulating heating pipes 14 are interconnected, and their two ends are respectively connected to the corresponding water tanks 9. An electronic level gauge 10 is fixedly connected to the inner wall of the top of each water tank 9.

[0021] In summary, this embodiment provides a high-efficiency and energy-saving blown film machine heating device, including an outer protective box 1 with heating through-holes 2 on both side walls. Two sets of guide rollers 3 are rotatably connected to the inner walls of both sides of the heating through-holes 2. Heating blocks 11 are fixedly connected to the top and bottom of one end of the heating through-holes 2. Water tanks 9 are provided on the inner walls of the outer protective box 1 at the top and bottom of the heating through-holes 2, and the two water tanks 9 are interconnected by pipes. A heat-conducting plate 12 is embedded and fixedly connected to the end of each water tank 9 near the heating block 11, and both heat-conducting plates 12 are in contact with the top and bottom of the corresponding heating blocks 11. Mounting grooves 13 are provided on the top and bottom of the end of the heating through-holes 2 away from the heating blocks 11. Multiple circulating heating pipes 14 are uniformly fixedly connected to the inner walls of the two mounting grooves 13, and the multiple circulating heating pipes 14 are interconnected, with their ends respectively connected to the corresponding water tanks 9.

[0022] A water inlet pipe 4 is fixedly connected to the top of one end of the outer protective box 1. The water inlet pipe 4 passes through one end of the outer protective box 1 and is located at the top of the water tank 9 to replenish water into the water tank 9. An electronic level gauge 10 is fixedly connected to the inner wall of the top of the water tank 9 to monitor the water level in the water tank 9.

[0023] The implementation principle of the high-efficiency and energy-saving blown film machine heating device in this application embodiment is as follows: When the device starts working, the controller 5 controls the heating block 11 to start heating according to preset parameters. The heat generated by the heating block 11 is transferred to the water in the water tank 9 through the heat conduction plate 12, causing the water temperature to rise. As the water temperature rises, the hot water flows into the circulating heating pipe 14 through the pipe, transferring the heat to the other end of the heating through-hole 2 to heat the thin film material passing through. At the same time, the water in the circulating heating pipe 14 returns to the water tank 9 after completing the heating task, forming a circulating heating system.

[0024] During the heating process, the electronic level gauge 10 monitors the water level in the water tank 9 in real time and transmits the data to the controller 5. When the water level falls below the set value, the controller 5 will issue an alarm and prompt for water replenishment. In addition, the controller 5 can adjust the heating power of the heating block 11 according to actual needs to achieve precise control of the heating temperature.

[0025] When the equipment needs to be shut down or maintained, the water in the water tank 9 can be drained through the drain pipe 7 and drain valve 8 to facilitate subsequent operations. Throughout the entire operation, the equipment achieves uniform heating and high-quality production of the thin film material through efficient and energy-saving heating methods and precise temperature control.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
