Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0063] Embodiment 1:

[0064] As Figures 1-6 shown, the present embodiment provides a plastic film cooling device, comprising:

[0065] cooling box 1;

[0066] feeding mechanism 2, arranged at the front side of cooling box 1, for introducing plastic film into cooling box 1;

[0067] The conveying mechanism 3 is arranged on both sides of the cooling box 1 and used for conveying the plastic film.

[0068] The water cooling mechanism 4 is arranged at the bottom of the cooling box 1 and used for cooling the plastic film.

[0069] The installation groove 11 is arranged at the bottom of the cooling box 1.

[0070] The blowing mechanism 5 is arranged in the installation groove 11 and used for blowing the cold air generated by the water cooling mechanism 4 to the plastic film.

[0071] The temperature sensor 12 is used for monitoring the temperature of the surface of the plastic film and feeding back the data to the control system 13.

[0072] The control system 13 adjusts the working state of the blowing mechanism 5 according to the feedback signal of the temperature sensor 12, so as to realize the efficient and uniform cooling effect.

[0073] In the technical scheme, the water cooling and air cooling are combined to provide the continuous and uniform cooling effect and ensure that the surface temperature of the film is kept in the ideal range; the temperature sensor 12 and the control system 13 are linked to automatically adjust the cooling mode according to the real-time temperature feedback, so as to improve the cooling effect and save energy; the control system 13 is used to automatically adjust the running state of the blowing mechanism 5, so that the cooling process is more accurate and efficient; the surface of the film is uniformly cooled in different areas, the local overheating is prevented, and the film quality and production efficiency are improved.

[0074] Work flow: the feeding mechanism 2 is responsible for introducing the plastic film into the cooling box 1. The feeding mechanism 2 is usually composed of rollers, conveyors or other conveying devices, which can ensure that the film enters the cooling box 1 smoothly and evenly, avoiding the film being pulled or wrinkled. The conveying mechanism 3 is distributed on both sides of the inside of the cooling box 1, which guides and conveys the plastic film along the inside of the box, ensuring that the film passes through the cooling area at an appropriate speed and stability, avoiding stagnation or stretching. The conveying process maintains the uniform cooling of the film, reducing the unevenness of the cooling effect. The water cooling mechanism 4 is located at the bottom of the cooling box 1, and at least three groups are evenly spaced; the water cooling mechanism 4 quickly removes the heat from the surface of the plastic film through the flow of cooling liquid, and the water cooling system can use the principle of circulating water cooling to continuously provide cooling function for the film. The setting of multiple water cooling mechanisms 4 ensures the uniform coverage of the cooling area, preventing the film from overheating locally. The blowing mechanism 5 blows the cold air from the water cooling mechanism 4 to the surface of the plastic film through the fan 53 or air flow equipment, further promoting the dissipation of heat. This combination of air cooling and water cooling effectively improves the cooling efficiency and enhances the uniformity of cooling, avoiding the problem of insufficient cooling in the water cooling part. The temperature sensor 12 monitors the surface temperature of the plastic film in real time, and the sensor feeds back the temperature data to the control system 13, which adjusts the operating state of the blowing mechanism 5 according to the temperature information. Specifically, when the temperature sensor 12 detects that the film temperature is too high, the control system 13 will instruct the blowing mechanism 5 to increase the wind speed and enhance the cooling; on the contrary, when the film temperature approaches the target temperature, the system will reduce the wind speed or temporarily stop, ensuring that the temperature is maintained within the predetermined range, which can accurately control the temperature change, ensure that the film is uniformly and efficiently cooled, thereby improving the production efficiency and reducing the energy consumption. In this way, the uniformity of the cooling effect can be ensured while ensuring efficient cooling, avoiding deformation or damage of the film surface due to overheating.

[0075] Example 2:

[0076] The present embodiment provides a plastic film cooling device, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0077] As shown in Figure 1 and Figure 2 , in the present embodiment, the optimized feeding mechanism 2 comprises:

[0078] a feeding groove 21 opened on the front side of the cooling box 1;

[0079] a rotating shaft 22 rotatably arranged at the upper and lower ends of the front side of the cooling box 1;

[0080] a feeding roller 23 arranged on the rotating shaft 22, the feeding roller 23 being located in the feeding groove 21, and the two feeding rollers 23 being symmetrically distributed;

[0081] The motor 24 is connected with the rotating shaft 22 through the output shaft.

[0082] The straight gears 25 are arranged on the rotating shaft 22, and the two straight gears 25 are engaged.

[0083] In the technical solution, the feeding mechanism 2 can efficiently and accurately feed the plastic film into the cooling box 1, ensuring the flatness of the film in the cooling box 1, providing an ideal film state for subsequent cooling. The feeding roller 23 cooperates with the rotating shaft 22 to realize stable conveying, avoiding the film from being jammed, wrinkled or torn during conveying. The motor 24 drives the rotating shaft 22 through the output shaft, ensuring the continuous operation of the feeding roller 23, providing continuous conveying force for the plastic film. The straight gears 25 are arranged for transmission, which can ensure the synchronous rotation of the feeding roller 23, avoiding the offset or uneven tension of the film during feeding.

[0084] The working process is as follows: the plastic film enters the feeding slot 21 from the outside, the feeding slot 21 guides the plastic film into the cooling box 1, ensuring smooth transition of the film to the feeding roller 23. The feeding roller 23 in the feeding slot 21 is driven by the motor 24 and the rotating shaft 22, the feeding roller 23 fixes and conveys the plastic film into the cooling box 1, and the feeding roller 23 ensures that the two sides of the film are clamped with uniform force, thereby avoiding the offset or unevenness of the film. The meshing of the gears enables the two feeding rollers 23 to rotate synchronously, ensuring that the film does not have uneven tension during conveying, avoiding wrinkles or uneven tension. The motor 24 is connected with the rotating shaft 22 through the output shaft, providing rotary power to drive the rotating shaft 22 and the feeding roller 23 system. The power output of the motor 24 accurately controls the rotating speed of the feeding roller 23, ensuring that the film can enter the cooling box 1 at a stable speed, thereby providing stable film supply for the subsequent cooling process. With the rotation of the feeding roller 23, the plastic film is smoothly conveyed into the cooling box 1, preparing for the subsequent water cooling and air cooling process. The entire feeding process ensures that the film is not stretched or wrinkled, maintaining a flat state when entering the cooling area, thereby realizing the uniformity and efficiency of the cooling effect. When the plastic film passes through the inside of the cooling box 1, the feeding roller 23 continuously conveys the film, while the water cooling and air cooling systems work cooperatively to achieve efficient cooling of the film. By accurately controlling the conveying process, the film is prevented from being damaged due to uneven cooling or stretching problems, resulting in poor cooling effect.

[0085] As shown in Figure 1 and Figure 2 , in this embodiment, the optimized conveying mechanism 3 comprises:

[0086] The transmission shaft 31 is rotatably arranged at the upper and lower ends of the front and rear sides of the cooling box 1.

[0087] The conveying rollers 32 are arranged on the transmission shafts 31 and located inside the cooling box 1;

[0088] The rack 33 is arranged outside the cooling box 1;

[0089] The second motor 34 is arranged on the rack 33 and connected with one of the transmission shafts 31;

[0090] The first gears 35 are arranged on the transmission shafts 31 and meshed with each other.

[0091] In the technical solution, the transmission shafts 31 and the conveying rollers 32 are arranged to ensure that the plastic film can move smoothly in the front-rear direction inside the cooling box 1, thereby avoiding wrinkles or damage caused by uneven conveying of the film. The second motor 34 is connected with the transmission shaft 31 and precisely controls the rotation of the conveying rollers 32 through gear meshing, so that the film can pass through the cooling box 1 at a constant speed, ensuring that the film is uniformly stressed during cooling and the cooling effect is consistent. Through the gear transmission system, the power of the second motor 34 can be efficiently transmitted to the transmission shaft 31, reducing direct friction loss and energy consumption, while ensuring the stability and reliability of the transmission process.

[0092] Work flow: The second motor 34 is installed on the rack 33 outside the cooling box 1 and connected with the transmission shaft 31 through the output shaft. The second motor 34 drives the transmission shaft 31 to rotate through electric energy, providing power for the conveying rollers 32, so that the film is conveyed in the front-rear direction inside the cooling box 1. Through the meshing of the gears, the two transmission shafts 31 are ensured to rotate synchronously, thereby realizing the synchronous rotation of the conveying rollers 32 on both sides. This synchronous drive ensures that the plastic film moves smoothly and uniformly in the conveying direction inside the cooling box 1. Under the joint action of the transmission shaft 31 and the conveying roller 32, the plastic film is smoothly conveyed into the cooling box 1. The rotation of the conveying roller 32 controls the direction and speed of the film movement, ensuring that the film passes through the cooling zone smoothly and avoiding deformation or tearing caused by uneven tension. When the film is conveyed into the cooling box 1, the water cooling and air cooling systems start to cool the film. The coordination between the conveying mechanism 3 and the cooling system ensures the stability of the film during cooling and maintains the consistency of the cooling effect. During the entire working process, the second motor 34 continuously provides stable power, and the transmission shaft 31 drives the conveying roller 32 through the gear, so that the movement of the film in the cooling box 1 remains stable. In this process, the temperature control system 13 and the conveying mechanism 3 in the cooling box 1 will coordinate with each other to ensure that the film is cooled in the most suitable state, thereby achieving the best cooling effect. At the same time, the conveying mechanism 3 continues to convey the film, so as to output the cooled film outside the cooling box 1, thereby realizing continuous conveying, improving energy efficiency, reducing unnecessary energy consumption, and finally ensuring the uniformity and reliability of the film cooling effect during production.

[0093] Embodiment 3:

[0094] The embodiment provides a plastic film cooling device, in addition to comprising the technical scheme of the above embodiment, further has the following technical features.

[0095] As shown in Figure 1 , Figure 2 and Figure 4 In this embodiment, the optimized water cooling mechanism 4 comprises:

[0096] The support frame 41 is arranged inside the cooling box 1, and the support frame 41 is at least three and is uniformly distributed along the length direction of the cooling box 1;

[0097] The water cooling pipe 42 is arranged in the support frame 41;

[0098] The water inlet pipe 43 is arranged at one end of the water cooling pipe 42, and the water inlet pipe 43 penetrates the cooling box 1;

[0099] The water tank 44 is located at the bottom of the cooling box 1;

[0100] The water delivery pipe 45 is arranged on the water tank 44;

[0101] The water pump 46 is connected to the water delivery pipe 45 at one end and connected to the water inlet pipe 43 at the other end;

[0102] The water outlet pipe 47 is arranged at the other end of the water cooling pipe 42, the water outlet pipe 47 penetrates the cooling box 1, and the end of the water outlet pipe 47 away from the water cooling pipe 42 is connected to the water tank 44.

[0103] In this technical solution, the water tank 44 is located at the bottom of the cooling box 1 and stores a certain amount of cooling water. After the water pump 46 is started, the water in the water tank 44 is transported to the water pump 46 through the water delivery pipe 45, preparing to enter the water cooling system. The water pump 46 provides flowing cooling water for the water cooling pipe 42 by transporting the cold water in the water tank 44 to the water inlet pipe 43. The cold water enters the water cooling pipe 42 from the water inlet pipe 43 and flows through the pipe to absorb and carry away the heat from the inside of the cooling box 1. Effectively reduce the temperature of the film. The cooling water in the water cooling pipe 42 absorbs heat and its temperature rises, becoming hot water. The hot water flows out through the other end of the water cooling pipe 42 and through the water outlet pipe 47, and the hot water is guided back into the water tank 44 and mixed with fresh cold water. The water in the water tank 44 is transported into the water inlet pipe 43 again by the water pump 46, enters the water cooling pipe 42, and continues the cooling cycle. This water circulation process can continue to ensure the efficiency of the cooling system. In the whole process, the cooling water circulates continuously, the water cooling pipe 42 continuously absorbs heat and is sent back to the water tank 44 by the water pump 46, so as to ensure that the film can gradually reach the required temperature in a stable cooling environment. In this way, the film temperature can be efficiently and stably reduced during the cooling process, preventing damage or quality degradation of the film due to excessive temperature. Through the layout of the support frame 41 and the water cooling pipe 42, the water cooling system can uniformly distribute the cooling water to ensure the consistency of the cooling effect. At the same time, the cooperation of the water pump 46 and the water tank 44 realizes the continuous circulation of water cooling, reduces energy consumption and improves work efficiency. The whole system operates in an automatic circulation, with strong energy-saving and environmental protection characteristics.

[0104] As shown in Figure 2 and Figure 4 , in this embodiment, the optimized water cooling pipe 42 is a purple copper elbow pipe.

[0105] In this technical solution, purple copper has excellent thermal conductivity and is a commonly used high-efficiency heat exchange material. Purple copper can more quickly conduct heat from the equipment to the water cooling pipe 42, thereby improving the heat dissipation efficiency. The design of the purple copper elbow pipe allows heat to be uniformly dispersed in a larger area, ensuring that the equipment will not be affected in performance due to excessive temperature during operation. Purple copper has strong corrosion resistance in common working environments, especially for the cooling liquid in the water circulation system, which can effectively reduce corrosion problems caused by long-term use. By using purple copper pipe, the service life of the cooling system is prolonged, reducing the frequency of maintenance and replacement of parts. The design of the purple copper elbow pipe increases the degree of bending of the pipe, which not only increases the contact area between the water flow and the pipe wall, but also enhances the disturbance effect of the water flow, allowing the water flow to carry away more heat when flowing in the pipe. The extension of the elbow pipe also helps the pipe to fully cover all parts of the equipment in a limited space, improving the cooling effect.

[0106] As shown in Figure 3 , Figure 4 andFigure 6 As shown, in this embodiment, the optimized blower mechanism 5 includes:

[0107] Dust cover 51 is installed at the bottom of cooling box 1 and located at the air inlet end of mounting slot 11;

[0108] Motor 52 is mounted on dust cover 51;

[0109] Fan 53 is located in mounting slot 11. Fan 53 is connected to the output shaft of motor 52 and is located below water cooling pipe 42.

[0110] In this technical solution, when the cooling device is started, the motor 52 begins to work and drives the fan 53 to rotate. The rotation of the fan 53 generates a strong airflow, which enters the cooling box 1 through the air inlet of the dust cover 51 and is delivered into the mounting slot 11. The airflow passes through the support frame 41 and acts on the surface of the water-cooling pipe 42, thereby directly blowing the cool air generated by the coolant in the water-cooling pipe 42 onto the surface of the plastic film, thus reducing the temperature of the film. Under the action of the fan 53, the airflow passes under the water-cooling pipe 42 as it passes through the mounting slot 11. The water-cooling pipe 42 usually circulates coolant to further reduce the internal temperature of the device. The cooperation between the water-cooling pipe 42 and the airflow makes the cooling effect more significant, ensuring that the film can be cooled down quickly. Throughout the cooling process, the combined action of the airflow and the water-cooling pipe 42 keeps the film within a certain temperature range. This temperature control method effectively avoids quality problems such as deformation and wrinkles caused by overheating of the film. Once the temperature of the plastic film drops to the predetermined range, the operation of the cooling device can be gradually stopped. At this time, fan 53 stops running, motor 52 stops working, and dust cover 51 serves to keep the interior clean and prevent the influence of the external environment. Through the airflow generated by the blower mechanism 5 and the cooling effect of the water cooling pipe 42, the device can effectively reduce the temperature of the film, thereby ensuring the stability and quality of the film during processing and avoiding defects caused by excessive temperature.

[0111] Example 4:

[0112] This embodiment provides a plastic film cooling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0116] A groove 63 is arranged at the top end of the support frame 62;

[0117] A rotating rod 64 is arranged in the groove 63 of the support frame 62;

[0120] A plastic film main body 67 is introduced into the cooling box 1 from the feeding chute 21, cooled by the water cooling mechanism 4, and led out of the cooling box 1 from the discharge chute 61, and wound on the winding wheel 65.

[0121] In the technical solution, the plastic film is introduced into the cooling box 1 from the feeding chute 21, and the feeding chute 21 and the discharge chute 61 are arranged correspondingly to ensure that the film can smoothly enter the cooling device. After the plastic film enters the cooling box 1, it is cooled by the water cooling mechanism 4 to reduce the temperature of the film, and the cooled plastic film is led out of the cooling box 1 from the discharge chute 61. At this time, the temperature of the film has been reduced, and the physical properties have been improved. The cooled film is guided to the winding mechanism 6 and starts to be wound on the winding wheel 65. The output shaft of the motor three 66 is connected with the rotating rod 64, and the rotation of the rotating rod 64 drives the winding wheel 65 to rotate, so that the cooled film is continuously wound on the winding wheel 65. The arrangement of the support frame 62 and the groove 63 provides stable support for the rotating rod 64 and ensures that the rotating rod 64 can rotate smoothly, avoiding the phenomenon that the film is stuck or irregularly wound during winding. The device realizes the automatic winding process by the cooperation of the motor three 66 and the rotating rod 64. The speed control of the motor three 66 can adjust the speed according to the actual situation of the film, so as to ensure that the film can be uniformly and stably wound, avoiding uneven winding or waste of the film. The device realizes effective cooling of the plastic film through the water cooling system, ensures that the temperature of the plastic film is reduced to the required range, and automatically winds the cooled film into a roll through the winding mechanism 6, greatly improving the production efficiency and automation degree.
