Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5As shown, this utility model provides a Teflon film shaping device, including a shaping box 1, a plurality of correspondingly arranged guide rollers 2 inside the shaping box 1, a film 3 wound on the guide rollers 2, baking lamps 4 evenly distributed on the top inner wall and bottom inner wall of the shaping box 1, a ventilation component 5 installed on the top of the shaping box 1, an inlet 6 and an outlet 7 respectively opened on the front and rear sides of the shaping box 1, the two ends of the film 3 passing through the inlet 6 and the outlet 7 respectively, and a dust removal component 8 installed at the inlet 6 position of the shaping box 1;

[0030] The ventilation assembly 5 includes an insulated box 501, inside which a heat exchange tube 502 is installed. One end of the heat exchange tube 502 passes through the insulated box 501, and the other end passes through the insulated box 501 and is connected to an air inlet pipe 503. The air inlet pipe 503 is connected to an air inlet 504, which is located on the shaping box 1. A ventilation pump 505 is connected to one side of the insulated box 501 via a pipe. The inlet 6 of the ventilation pump 505 is connected to an air outlet pipe 506, which is connected to an air outlet 5. 07. The air outlet 507 is located on the shaping box 1. A filter adsorption component 508 is installed at the corresponding position of the heat insulation box 501. The filter adsorption component 508 connects the air inside and outside the heat insulation box 501, exhausts the air inside the shaping box 1, and transfers the heat in the exhaust air to the intake air to reduce heat waste and thus reduce energy consumption. In addition, the exhaust air is filtered and adsorbed to adsorb some harmful substances to avoid affecting the health of the staff and the quality of the film.

[0031] Specifically, the dust removal component 8 includes an ion fan 801. The outlet 7 of the ion fan 801 is connected to a guide pipe 802, and the guide pipe 802 is connected to an exhaust pipe 803. Two exhaust pipes 803, which are correspondingly located above and below the inlet 6, are respectively located above and below the inlet 6. The exhaust pipes 803 are equipped with equidistant and inclined air outlets 804. Before the Teflon film is heat-set, the airflow discharged by the ion fan 801 is blown onto the Teflon film to remove dust that adheres to the surface of the Teflon film due to static electricity, thus avoiding affecting the quality of the Teflon film.

[0032] Furthermore, the heat exchange tube 502 inside the insulation box 501 is curved, which extends the travel path of the air entering the shaping box 1 and increases the heat transfer time, so as to facilitate the heating of the air.

[0033] Furthermore, the heat insulation box 501 is equipped with a corresponding baffle 9, which is fixedly connected to the heat exchange tube 502, extending the travel path of the exhaust gas and allowing it to exchange heat with the incoming air for a sufficient time.

[0034] It is worth noting that the air inlet 504 and the air outlet 507 are located above and below the membrane 3, respectively.

[0035] It is worth noting that the filter adsorption assembly 508 includes a vent housing 5081, and a first filter screen 5082 and a second filter screen 5083 are respectively provided in the vent housing 5081. The space between the first filter screen 5082 and the second filter screen 5083 is filled with adsorption filler 5084, and the filter screen and filler are used to filter and adsorb harmful substances in the gas.

[0036] It is worth mentioning that the pore size of the first filter screen 5082, which is located near the air inlet end of the vent housing 5081, is larger than that of the second filter screen 5083. The different pore sizes can improve the filtration effect.

[0037] Among them, the baking lamp 4, the air exchange pump 505, and the ion fan 801 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: The film 3 moves within the shaping chamber 1 under the influence of the traction device. The baking lamp 4 provides sufficient heat to keep the film 3 within a suitable temperature range for heat shaping of the Teflon film. The ion fan 801 of the dust removal component 8 is started, and the airflow passes through the air guide pipe 802 and the exhaust pipe 803 before being discharged from the air outlet 804. This removes dust adhering to the surface of the Teflon film due to static electricity, preventing it from affecting the quality of the Teflon film. The air exchange pump 505 of the ventilation component 5 is started, and the gas in the shaping chamber 1 is discharged through the air outlet 507, the air outlet pipe 506, and the air exchange pump 505. The air is introduced into the heat insulation box 501, which in turn creates a negative pressure in the shaping box 1. This allows outside air to enter through the air inlet of the heat exchange pipe 502. The intake air undergoes heat exchange within the heat insulation box 501 to generate high-temperature air. This high-temperature air then enters the shaping box 1 through the air inlet 504 after passing through the air inlet pipe 503. The gas inside the heat insulation box 501 is then discharged after passing through the filter adsorption component 508. The heat in the discharged air is transferred to the intake air to reduce heat waste and thus energy consumption. The discharged air is also filtered to adsorb some harmful substances, preventing them from affecting the health of the staff and the quality of the film 3.
