[0002] Car wrap film, also known as transparent car body film or car paint protection film, is essentially a polyurethane film. This film has super toughness and wear resistance, is impact resistant, and can isolate the car paint from the air after being applied.
[0003] The existing calendering method is generally hot pressing. The temperature of the car wrap film after hot pressing is relatively high, and it is not fully formed. As a result, the car wrap film is relatively soft at high temperature, which makes it very inconvenient for operators to cut the car wrap film later, thus reducing the production efficiency of car wrap film production.

[0022] The present invention will be further described below with reference to the embodiments.
[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0024] Please see Figure 1-5 This utility model provides a calendering mechanism for producing automotive coating film, including a first transmission table 1, a second transmission table 2 fixedly connected to the rear side of the first transmission table 1, and four support legs 9 fixedly connected to the bottom of both the first transmission table 1 and the second transmission table 2. A first automotive coating film calendering roller 3 is arranged inside the second transmission table 2, and a support plate 4 and a cooling mechanism 7 are arranged on the top of the second transmission table 2. The cooling mechanism 7 is located near the rear side of the support plate 4. There are two support plates 4, and an adjustment mechanism 5 is arranged between the two support plates 4. A second automotive coating film calendering roller 6 is arranged inside the adjustment mechanism 5, and the second automotive coating film calendering roller 6 is located above the first automotive coating film calendering roller 3.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, the cooling mechanism 7 includes fixed legs 71. The bottom of the fixed legs 71 is fixedly connected to the top of the second transmission platform 2. There are four fixed legs 71. A fixed plate 72 is fixedly connected between the four fixed legs 71. A water tank 73 and two first electric push rods 77 are fixedly connected to the top of the fixed plate 72. The water tank 73 is located between the two first electric push rods 77. A water pump 74 is fixedly connected to the top of the water tank 73. Water guide pipes 75 are fixedly installed on both sides of the water pump 74. A threaded telescopic hose 76 is fixedly connected to the bottom of the water guide pipe 75. The threaded telescopic hose 76 completely penetrates the fixed plate 72. A cooling plate 78 is fixedly connected to the output end of the first electric push rod 77. The end of the threaded telescopic hose 76 extends into a liquid storage tank opened inside the cooling plate 78. A drain pipe 711 is fixedly connected to the rear side of the cooling plate 78.
[0026] like Figure 3 As shown, a heat-absorbing plate 79 is fixedly connected inside the liquid storage tank, and a through groove 710 is opened inside the heat-absorbing plate 79.
[0027] The heat absorber plate 79 can increase the heat exchange effect of the coolant, making the car cover film cool down faster.
[0028] like Figure 2 and Figure 3 As shown, heat dissipation fins 712 are fixedly connected to the outer surfaces of both the front and rear ends of the cooling plate 78. The heat dissipation fins 712 have horizontal and vertical heat dissipation holes inside, and the horizontal and vertical heat dissipation holes are integrally formed.
[0029] The heat dissipation fins 712, together with the horizontal and vertical heat dissipation holes, can increase the contact area between the cooling plate 78 and the outside air, dissipate heat from the coolant after heat exchange, and allow the cooling plate 78 to be used quickly.
[0030] In use, the first electric push rod 77 is activated to move the cooling plate 78 to press against the rolled-up car cover film, so that the bottom of the cooling plate 78 contacts the car cover film. Then, the water pump 74 can be activated. After the water pump 74 is activated, it can guide the coolant inside the water tank 73 into the water guide pipe 75, and then guide the coolant into the first electric push rod 77 through the water guide pipe 75 and the threaded telescopic hose 76. The first electric push rod 77 is filled with coolant. The threaded telescopic hose 76 has a certain degree of telescopic and elastic effect, which can be used to raise and lower the first electric push rod 77. After the first electric push rod 77 is filled with coolant, it can absorb the heat of the car cover film and displace the heat of the car cover film. The heat absorption plate 79 inside the water tank 73 is made of metal material, which has a good heat absorption effect and can accelerate the cooling speed of the car cover film, allowing the car cover film to form quickly. The coolant after absorbing heat is discharged through the drain pipe 711. The heat dissipation fins 712 can work with the coolant to further displace the heat of the car cover film and improve the heat dissipation effect.
[0031] like Figure 1 and Figure 5 As shown, guide grooves are provided on one side of the outer wall of both support plates 4. The adjustment mechanism 5 includes a threaded rod 51, which is threadedly connected to the inside of one of the support plates 4. The bottom of the threaded rod 51 is connected to a moving column 53 via a bearing. A guide rod 52 is fixedly installed in the guide groove provided inside the other support plate 4. A guide column 54 is slidably connected to the outer wall of the guide rod 52. The second coating film calendering roller 6 is fixedly connected between the guide column 54 and the moving column 53.
[0032] When in use, the distance between the first car wrap film calendering roller 3 and the second car wrap film calendering roller 6 can be adjusted according to the different thicknesses of the car wrap film. During adjustment, the threaded rod 51 can be rotated. After the threaded rod 51 rotates, it works with the guide rod 52 and the guide column 54 to drive the moving column 53 to rise and fall. Then, the moving column 53 drives the second car wrap film calendering roller 6 to rise and fall, moving closer to or further away from the first car wrap film calendering roller 3, which is convenient for calendering car wrap films of different thicknesses.
[0033] like Figure 1 and Figure 4 As shown, a limiting mechanism 8 is provided inside the first transmission platform 1. The limiting mechanism 8 is used to limit the transmission of the car wrap film. The limiting mechanism 8 includes a second electric push rod 81, which is fixedly connected to one side of the first transmission platform 1. The output end of the second electric push rod 81 is fixedly connected to a limiting plate 82.
[0034] When transferring the car wrap film, two second electric push rods 81 can be activated. After the two second electric push rods 81 are activated, they drive two limit plates 82 to move in opposite directions, limiting the car wrap film of different sizes, so that the transfer position of the car wrap film will not be deviated, and ensuring the calendering effect of the car wrap film.
[0035] The working principle and usage process of this utility model are as follows: In use, the first electric push rod 77 is activated to drive the cooling plate 78 to press tightly against the rolled-out car cover film, making the bottom of the cooling plate 78 contact the car cover film. Then, the water pump 74 can be activated. After the water pump 74 is activated, it can guide the coolant inside the water tank 73 into the water guide pipe 75, and then the water guide pipe 75, together with the threaded telescopic hose 76, guides the coolant into the first electric push rod 77, allowing the first electric push rod 77 to be filled with coolant. The threaded telescopic hose 76 has a certain degree of extension and elasticity, which can cooperate with the first electric push rod 77 to raise and lower. After the first electric push rod 77 is filled with coolant, it can absorb the heat of the car cover film and displace the heat of the car cover film. The heat absorption plate 79 inside the water tank 73 is made of metal material, which has a good heat absorption effect and can accelerate the cooling speed of the car cover film, allowing the car cover film to form quickly. The coolant after absorbing heat is discharged through the drain pipe 711. The heat dissipation fins 712 can work with the coolant to further displace the heat of the car cover film, improving the heat dissipation effect.
