The heating assembly 5 is located on the side adjacent to the tensioning assembly 4. The heating assembly 5 includes a protective housing 51 disposed above the base 1. The protective housing 51 facilitates the connection and installation of the fixing plate 52 and the fixing bracket 55, and protects the heating box 591. The fixing plate 52 is fixedly connected to one side of the protective housing 51. The fixing plate 52 facilitates the connection and installation of guide rollers 53. Two guide rollers 53 are connected to one side of the fixing plate 52. The guide rollers 53 facilitate the guidance of PET film into the protective housing 51.

[0028] refer to Figure 2 , Figure 3 and Figure 4 As shown, the cleaning mechanism 47 includes a cleaning roller 471 connected to one side of the support plate 46.

[0029] refer to Figure 5 and Figure 6As shown, the heating mechanism 59 includes a heating box 591 fixed to the end of the connecting rod 58. The heating box 591 facilitates the connection and installation of the air inlet pipe 592, the air guide plate 594, and the high-temperature sponge layer 596. Several air inlet pipes 592 are fixedly connected to one side of the heating box 591, allowing air to easily enter the heating box 591. A blower 593 is installed inside the air inlet pipe 592, which facilitates blowing air through the air guide plate 594, increasing the air pressure inside the heating box 591. Below the blower 593, inside the heating box 591, is an air guide plate 594, which guides the air blown by the blower 593 to various air guide holes 595. The air guide plate 594 has several through-holes 595 inside. By setting the air guides 595, the air blown by the blower 593 can be evenly guided to the high-temperature sponge layer 596. The high-temperature sponge layer 596 is connected below the air guide plate 594. By setting the high-temperature sponge layer 596, the air blown out of the air guides 595 can be easily dispersed, so that the air can be evenly blown onto the surface of the PET film. The connecting rod 58 passes through the inner wall of the protective housing 51 and is slidably connected in the inner wall of the protective housing 51. The air guides 595 are evenly distributed inside the air guide plate 594. Several electric heating wires 597 are set in the air guides 595. By setting the electric heating wires 597, the air passing through the air guides 595 can be easily heated, thereby heating the PET film.
[0030] refer to Figure 1 and Figure 5 As shown, a controller 9 is provided on one side of the protective housing 51. By setting the controller 9, the operation of the blower 593 and the electric heating wire 597 can be easily controlled. A temperature sensor 10 is provided on one side of the heating box 591. By setting the temperature sensor 10, the temperature of the air passing through the high-temperature sponge layer 596 can be easily detected in real time. It should be noted that the output terminal of the temperature sensor 10 is electrically connected to the input terminal of the controller 9 through a wire, and the output terminal of the controller 9 is electrically connected to the input terminals of the blower 593 and the electric heating wire 597 through a wire.
[0031] Working principle: The PET film is first passed through and connected to the tension roller 45, cleaning roller 471, and guide roller 53 in sequence, passing between the heating box 591 and exiting from the other side of the protective housing 51. During the PET film conveying process, the servo motor 41 is started. The servo motor 41 drives gear 1 42 and gear 2 43 to rotate, thereby driving the disc 44 to rotate. When the disc 44 rotates, it drives the two tension rollers 45 to rotate, thereby tightening the PET film. When the PET film passes through the cleaning roller 471, the cleaning roller 471, driven by the pressure spring 474 and the bearing seat 472, presses against the surface of the PET film, thereby adhering to the impurities attached to the surface of the PET film. To reduce impurities remaining on the surface of the PET film, when the blower 593 and the electric heating wire 597 are running, the blower 593 can blow air through the air guide plate 594. When the air passes through the air guide hole 595, it can be heated by the electric heating wire 597. The heated air is blown onto the high-temperature sponge layer 596 and dispersed, so that the hot air passing through the high-temperature sponge layer 596 can be evenly blown onto the upper and lower surfaces of the PET film, thereby heating the PET film evenly. At the same time, the temperature sensor 10 can detect the temperature of the air blown from the high-temperature sponge layer 596 in real time, so that the PET film can be heated at a suitable temperature, which is beneficial to the subsequent heat transfer of the PET film and improves the heat transfer processing effect of the PET film.
