[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0020] Some embodiments of the present invention are described below with reference to the accompanying drawings. Example 1

[0021] Combine Figure 1-4 As shown, this embodiment provides a polyester film cooling and forming device, including: a main body mechanism 100.

[0022] Among them, the main mechanism 100 includes a frame 110, multiple cooling rollers 120 rotatably mounted on opposite inner walls of the frame 110, a bracket 130 symmetrically fixed on the frame 110, a water supply member 140 arranged on both sides of the frame 110 and rotatably connected to each cooling roller 120, multiple U-shaped blowing pipes 150 fixed on the bracket 130 and extending into the inner cavity of the frame 110 and clamped on the outside of the cooling roller 120, a blowing member 160 mounted on the top of the U-shaped blowing pipe 150 and connected to the U-shaped blowing pipe 150, and a film body 170 that passes through multiple cooling rollers 120 in sequence.

[0023] The frame 110 is used to install other components to ensure the stability of each component. The cooling roller 120 is rotatably installed on the relative inner wall of the frame 110 in a serpentine arrangement to guide the film body 170 and cool the film body 170 as it passes by.

[0024] The water supply component 140 on one side is used to supply cooling water into the cooling roller 120, and the water supply component 140 on the other side is used to discharge the cooling water after absorbing heat in the cooling roller 120, forming a cooling water circulation in the inner cavity of the cooling roller 120. The water supply component 140 includes a U-shaped water pipe 141 arranged on one side of the frame 110 and a plurality of connecting pipes 142 installed on the U-shaped water pipe 141. The U-shaped water pipe 141 can connect the multiple connecting pipes 142 together to facilitate centralized water supply and drainage. The connecting rod connects the U-shaped water pipe 141 with the end of the cooling roller 120.

[0025] In addition, the interior of the cooling roller 120 is provided with a cavity to facilitate the passage of cooling water. An annular groove 121 is opened on the inner wall at both ends of the cooling roller 120, and an annular protrusion 1421 is provided at the end of the connecting pipe 142. The two are rotated and engaged with each other to prevent the connecting pipe 142 from affecting the rotation of the cooling roller 120.

[0026] The bracket 130 is used to install the U-shaped blowing pipe 150. The U-shaped blowing pipe 150 is arranged in an array and clamped on both sides of each cooling roller 120. It can blow high-speed air to the surface of the film body 170 to cool it down. The opposite inner side surfaces of the U-shaped blowing pipe 150 are provided with oblique air holes 151 in an array, so that the high-speed airflow can be blown out along the direction of movement of the film body 170, reducing the wind force on the film body 170, forming a high-speed airflow on the surface of the film body 170, taking away the heat on the film body 170, and avoiding damage to the film body 170.

[0027] The blowing member 160 is used to send high-speed airflow into the U-shaped air blowing pipe 150. The blowing member 160 includes a tube body 161 fixed at the top of the U-shaped air blowing pipe 150, multiple high-speed fans 162 installed on the inner wall of the tube body 161, and a filter 163 fixed on the inner wall of the tube body 161. The tube body 161 is connected to the U-shaped air blowing pipe 150 and is used to install the high-speed fans 162. The high-speed fans 162 suck in external air and accelerate it into the U-shaped air blowing pipe 150. The filter 163 can prevent external dust from entering.

[0028] The working principle and usage process of the present invention are as follows: when in use, the film body 170 is passed through the cooling roller 120 in sequence. When the film is cooled, cooling water is fed in through the U-shaped water pipe 141 on one side, and then enters the cooling roller 120 through the connecting pipe 142. At this time, when the film body 170 passes through the cooling roller 120, the heat on the film body 170 is transferred to the cooling water through the cooling roller 120, and the film body 170 is cooled. Thereafter, the cooling water that absorbs the heat is sent out through the water delivery member 140 on the other side, and at the same time, the high-speed fan 162 is started to suck the outside air into the tube body 161 and accelerate it into the U-shaped blowing pipe 150. After the high-speed cavity enters the U-shaped blowing pipe 150, it is blown out along the oblique air hole 151, forming a high-speed airflow on the surface of the film body 170, taking away the heat on the film body 170, and realizing the cooling of the film body 170.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
