[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 , a cooling mechanism for polypropylene drawn film production in this embodiment includes a box body 1 and a film body 101. A cooling mechanism is arranged inside the box body 1, and a control component is arranged outside the box body 1.

[0025] Embodiment 1: Five guide rollers are rotatably connected inside the box body 1. The film body 101 is in contact with the guide rollers. The guide rollers are used to guide the film body 101, which facilitates the cooling treatment of the film during transportation and reduces the deviation and wrinkles of the film body 101.

[0026] Among them, the cooling mechanism includes two partitions 102 fixedly connected to the box body 1. A cooling chamber 103 is arranged inside the box body 1. A water inlet pipe 2 communicated with the cooling chamber 103 is fixedly connected to the back surface of the box body 1. An inlet opening is formed in the back surface of the box body 1. The water inlet pipe 2 is communicated with the cooling chamber 103 through the inlet opening. An inlet valve is arranged inside the water inlet pipe 2. The other end of the water inlet pipe 2 is fixedly connected to a water supply component. When the inlet valve is opened, cooling water enters the inside of the cooling chamber 103 through the water inlet pipe 2 to cool down the film body 101 located inside the cooling chamber 103. A recovery pipe 3 communicated with the cooling chamber 103 is fixedly connected to the left side of the box body 1. A recovery opening is formed in the left side of the box body 1. The recovery pipe 3 is communicated with the cooling chamber 103 through the recovery opening. A control valve is arranged inside the recovery pipe 3. When the temperature of the cooling water inside the cooling chamber 103 reaches a certain value, the control valve is opened, and the heated cooling water is discharged through the recovery pipe 3, which is convenient for recovering and utilizing the residual heat on the film body 101.

[0027] In addition, electric push rods 4 are fixedly connected to both the inner top wall and the inner bottom wall of the box body 1. A fixing plate 5 is fixedly connected to the output end of the electric push rod 4. Sponge blocks 6 are fixedly connected to the opposite sides of the two fixing plates 5. The two sponge blocks 6 are respectively located at the top and the bottom of the film body 101. The sponge blocks 6 are attached to the film body 101. When the two electric push rods 4 are energized and extended, they push the two fixing plates 5 and the sponge blocks 6 to move relatively, so that the sponge blocks 6 are attached to the film body 101, and the sponge blocks 6 adsorb the cooling water on the film body 101, which is convenient for dehumidifying the film body 101.

[0028] Secondly, a tension adjusting component 7 is fixedly connected to the inner top wall of the box body 1. A ventilation fan 8 is arranged on the front surface of the box body 1. A dust-proof net 9 is arranged on the back surface of the box body 1. The tension adjusting component 7 includes an electric telescopic rod 71, a mounting bracket 72 and a roller 73. The electric telescopic rod 71 is fixedly connected to the inner top wall of the box body 1. The mounting bracket 72 is fixedly connected to the output end of the electric telescopic rod 71. The roller 73 is rotatably connected to the mounting bracket 72. When the electric telescopic rod 71 is energized and extended, it pushes the mounting bracket 72 and the roller 73 to move downward to adjust the tension of the film body 101, reducing the overlap and accumulation of the film body 101. At the same time, the ventilation fan 8 is energized to rotate, accelerating the air flow in the space around the film body 101 and accelerating the dissipation of the moisture on the film body 101.

[0029] It should be noted that by setting the cooling mechanism, it is convenient to cool and dehumidify the polypropylene film, reduce the residual cooling water on the film, and facilitate the next process treatment of the polypropylene film, solving the problem that there is no dehumidification structure. During the process of using the cooling mechanism to cool down the polypropylene film, it is not convenient to remove the residual cooling water on the film, which is likely to cause the cooling water to adsorb on the film and is not conducive to the next process treatment of the polypropylene film.

[0030] Specifically, when using the cooling mechanism to cool down the polypropylene film, the two electric push rods 4 are energized to extend, pushing the two fixed plates 5 and the sponge blocks 6 to move relative to each other, so that the sponge blocks 6 are attached to the film body 101. The cooling water enters the inside of the cooling chamber 103 through the water inlet pipe 2, and cools down the film body 101 located inside the cooling chamber 103. The sponge blocks 6 adsorb the cooling water on the film body 101, facilitating the dehumidification of the film body 101. Moreover, the tension of the film body 101 is adjusted by the tension adjustment component 7 being energized to extend, reducing the overlap and accumulation of the film body 101. At the same time, the ventilation fan 8 is energized to rotate, accelerating the air flow in the space around the film body 101 and speeding up the dissipation of the moisture on the film body 101, thereby achieving the cooling and dehumidification of the polypropylene film, reducing the residue of the cooling water on the film, and facilitating the next process treatment of the polypropylene film.

[0031] Embodiment 2: Please refer to Figures 1 to 4 , the control component includes an intelligent control device 13 fixedly connected to the box body 1. A temperature sensor 10 and a first liquid level sensor 11 located inside the cooling chamber 103 are fixedly connected to the inner bottom wall of the box body 1. A second liquid level sensor 12 located inside the cooling chamber 103 is fixedly connected to the left inner wall of the box body 1. The temperature sensor 10 is electrically connected to the intelligent control device 13, and both the first liquid level sensor 11 and the second liquid level sensor 12 are electrically connected to the intelligent control device 13. The intelligent control device 13 is electrically connected to the water inlet valve inside the water inlet pipe 2, and the intelligent control device 13 is electrically connected to the control valve inside the recovery pipe 3. The temperature sensor 10 monitors the water temperature inside the cooling chamber 103 in real time. When the temperature sensor 10 monitors that the water temperature inside the cooling chamber 103 reaches a certain value, the intelligent control device 13 opens the control valve inside the recovery pipe 3 to discharge the heated cooling water. When the height of the cooling water inside the cooling chamber 103 reaches the first liquid level sensor 11, the intelligent control device 13 closes the control valve inside the recovery pipe 3 and opens the water inlet valve inside the water inlet pipe 2 to change the cooling water inside the cooling chamber 103.

[0032] It should be noted that by setting the control component, it is convenient to replace the cooling water, facilitate the cooling and temperature reduction of the polypropylene film, and is conducive to the recovery and utilization of the residual heat on the polypropylene film.

[0033] Specifically, during the process of using the cooling mechanism to cool down the polypropylene film, the temperature sensor 10 continuously monitors the water temperature inside the cooling chamber 103. When the temperature sensor 10 detects that the water temperature inside the cooling chamber 103 reaches a certain value, the intelligent control device 13 opens the control valve inside the recovery pipe 3 to drain the heated cooling water. When the water level of the cooling water inside the cooling chamber 103 reaches the first liquid level sensor 11, the intelligent control device 13 closes the control valve inside the recovery pipe 3 and opens the water inlet valve inside the water inlet pipe 2 to replace the cooling water inside the cooling chamber 103.

[0034] The working principle of the above embodiment is as follows:

[0035] (1) For the cooling mechanism for producing polypropylene drawn film, when using the cooling mechanism to cool down the polypropylene film, the two electric push rods 4 are energized to extend, pushing the two fixing plates 5 and the sponge block 6 to move relatively, so that the sponge block 6 is attached to the film body 101. The cooling water enters the inside of the cooling chamber 103 through the water inlet pipe 2 to cool down the film body 101 located inside the cooling chamber 103. The sponge block 6 adsorbs the cooling water on the film body 101, which is convenient for dehumidifying the film body 101. Moreover, the tension of the film body 101 is adjusted by the tension adjusting component 7 being energized to extend, reducing the overlap and accumulation of the film body 101. At the same time, the ventilation fan 8 is energized to rotate, accelerating the air flow in the space around the film body 101 and accelerating the dissipation of the moisture on the film body 101, so as to achieve the cooling and dehumidification of the polypropylene film, reduce the residue of the cooling water on the film, and facilitate the next process treatment of the polypropylene film.

[0036] (2) For the cooling mechanism for producing polypropylene drawn film, during the process of using the cooling mechanism to cool down the polypropylene film, the temperature sensor 10 continuously monitors the water temperature inside the cooling chamber 103. When the temperature sensor 10 detects that the water temperature inside the cooling chamber 103 reaches a certain value, the intelligent control device 13 opens the control valve inside the recovery pipe 3 to drain the heated cooling water. When the water level of the cooling water inside the cooling chamber 103 reaches the first liquid level sensor 11, the intelligent control device 13 closes the control valve inside the recovery pipe 3 and opens the water inlet valve inside the water inlet pipe 2 to replace the cooling water inside the cooling chamber 103.
