Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] See Figures 1-4 As shown in the embodiment of this utility model, a heating system for an oven 1 is proposed. As a main component of the coating machine, it dries the coated film. Specifically, it includes an oven 1 and a lifting cylinder 2 installed on the top of the oven 1. An inner liner 3 is installed on the telescopic rod of the lifting cylinder 2 that extends into the oven 1. Several nozzles 4 are arranged in an array on the inner liner 3. The distance between the nozzles 4 and the film passing through the inner liner 3 is adjusted by adjusting the height of the inner liner 3 through the lifting cylinder 2, thereby ensuring temperature control during the drying process. The oven 1 mainly maintains a temperature suitable for the film drying requirements. In order to pre-form a drying air at a preset temperature outside the oven 1 and then deliver it into the oven 1, a hot air guide box 5 is provided on one side of the oven 1. The hot air guide box 5 is equipped with a heat source pipe 6 for connecting to the hot air source. The hot air guide box 5 is provided with an air inlet pipe 7 that connects to the inner liner 3. A corrugated pipe 8 is connected between the air inlet pipe 7 and the hot air guide box 5. By connecting the air inlet pipe 7 through the corrugated pipe 8, the air inlet pipe 7 can be tilted after adjusting the height of the inner liner 3, thus maintaining the communication between the hot air guide box 5 and the inside of the oven 1.

[0026] Generally, during the drying process, the internal film will move continuously. Specifically, the oven 1 is also provided with a film guide roller mechanism 17 located below the inner liner 3. The film is moved by the film guide roller mechanism 17. The film guide roller mechanism 17 used is the existing structure currently used in the oven 1.

[0027] Meanwhile, a fresh air supply system is also provided on the hot air guide box 5. A circulating air system is provided between the hot air guide box 5 and the oven 1, so that external hot air flows into the hot air guide box 5 through the heat source pipe 6, while the warm air in the oven 1 flows into the hot air guide box 5 through the circulating air system. The supply air system introduces external cold air into the hot air guide box 5, thereby forming an airflow that meets the drying requirements in the hot air guide box 5. Finally, all of the airflow is delivered to the inner liner 3 through the air inlet pipe 7 and then directed towards the film through the nozzle 4, thereby improving the internal heat utilization efficiency.

[0028] Specifically, the air supply system includes an intake fan 9 integrated on the hot air guide box 5. The hot air guide box 5 is equipped with a high-efficiency filter 10 for filtering the air delivered by the intake fan 9. The high-efficiency filter 10 is located on the air inlet side of the air inlet pipe 7. At the same time, a cold air duct 11 connected to the intake fan 9 is provided on the hot air guide box 5. The cold air introduced by the intake fan 9 through the cold air duct 11 is filtered by the built-in high-efficiency filter 10, thereby supplementing the hot air guide box 5 with external cold air according to the temperature requirements, forming a fresh air supply.

[0029] Specifically, the circulating air system includes a first exhaust duct 12 connecting the hot air guide box 5 to the bottom of the oven 1, and a second exhaust duct 13 connecting the hot air guide box 5 to the top of the oven 1. The outlet end of the second exhaust duct 13 is connected to an exhaust fan 14, which circulates the warm air inside the oven 1 to the hot air guide box 5. The air temperature discharged from the first exhaust duct 12 is higher, while the air temperature discharged from the second exhaust duct 13 is lower. To prevent backflow between the first exhaust duct 12 and the second exhaust duct 13, one-way valves are provided on both the first exhaust duct 12 and the second exhaust duct 13.

[0030] Meanwhile, in order to facilitate the assembly and maintenance of internal components inside the oven 1, at least two openable rotating doors 15 are provided on the oven 1, and door locks are provided on the oven 1 to lock the rotating doors 15.

[0031] Meanwhile, multiple support feet 16 and fixing plates on the support feet 16 are provided at intervals at the bottom of the hot air guide box 5. The hot air guide box 5 is fixedly installed by the support feet 16 and the fixing plates. Multiple height-adjustable feet are provided at intervals at the bottom of the oven 1. The height-adjustable feet are used to maintain the balanced installation of the oven 1. The height-adjustable feet can be made of threaded rods, nuts, etc.
