DETAILED DESCRIPTION

[0027] The utility model will be further described below in combination with the drawings and examples.

[0028] Please refer to Figures 1-6The utility model provides a kind of high-barrier coating composite film pressing device, including machine table 1, the film combination component 2, air cooling component 3 and multiple water cooling components 4 are sequentially arranged in machine table 1, the film combination component 2 includes the connecting plate 21 fixedly connected between the two sides of the inner wall of machine table 1 and the fixed roller 22 rotationally connected between the two sides of the inner wall of machine table 1, the middle part of the connecting plate 21 is screw-threaded with screw rod 23, the top of the screw rod 23 is fixedly connected with handle 24, the bottom of the screw rod 23 is rotationally connected with fork 25, the fork 25 can slide along the inner wall of machine table 1, the two sides of the inner wall of the fork 25 are rotationally connected with movable roller 26, and the movable roller 26 is located directly above the fixed roller 22.

[0029] Specifically, the top of the screw rod 23 is fixedly connected with a handle 24, and the operator can control the up-down movement of the screw rod 23 by rotating the handle 24, thereby adjusting the height of the movable roller 26, and the movable roller 26 is located directly above the fixed roller 22, and its up-down movement can adjust the pressure between the movable roller 26 and the fixed roller 22, thereby adapting to the pressing needs of films of different thicknesses.

[0030] Further, two guide rods 11 are rotationally connected between the two sides of the inner wall of the machine table 1, and the two guide rods 11 are located on the side of the film combination component 2 away from the air cooling component 3.

[0031] Specifically, the guide rods 11 are located on the side of the film combination component 2 away from the air cooling component 3, which means that they are located in the starting part of the composite film pressing process, and the guide rods 11 can improve the transmission accuracy and stability of the composite film in the pressing device and reduce quality problems caused by film material deviation or uneven tension.

[0032] Further, the adjacent water cooling components 4 are distributed in an up-down staggered manner, wherein the water cooling roller 41 of the upper water cooling component 4 is located above the limiting roller 42, and the water cooling roller 41 of the lower water cooling component 4 is located below the limiting roller 42.

[0033] Specifically, when the composite film passes through the water cooling component 4, it can form an alternating up-down path between different water cooling rollers 41, and the staggered distribution of the water cooling components 4 causes the composite film to form a serpentine transmission path when passing through, which helps to increase the contact area and contact time of the composite film with the water cooling roller 41, and the two sides of the composite film are alternately cooled, thereby improving the cooling effect.

[0034] Further, the number of water cooling components 4 is at least 2, the water cooling component 4 includes a water cooling roller 41 installed between the two sides of the inner wall of the machine table 1, two limiting rollers 42 are provided beside the water cooling roller 41, the limiting rollers 42 are rotationally connected between the two sides of the inner wall of the machine table 1, and the water cooling roller 41 and the two limiting rollers 42 are arranged in a "C" shape with the composite film therebetween.

[0035] Specifically, the function of these limiting rollers 42 is to guide and stabilize the running path of the composite film, ensure that the composite film can be correctly aligned when passing through the water-cooled roller 41, and form a "C" shaped layout, which enables the composite film to more fully contact the surface of the water-cooled roller 41 when passing through the water-cooled assembly 4, thereby improving the cooling efficiency. At the same time, this design also helps to evenly distribute the tension of the composite film, reducing quality problems caused by uneven tension.

[0036] Further, the water-cooled roller 41 is rotatably embedded with a communication pipe 411 at both ends, and the two communication pipes 411 are fixedly embedded on the two side walls of the machine table 1. The water-cooled roller 41 is provided with a filling cylinder 412, and a plurality of support rods 413 are fixed between the filling cylinder 412 and the inner wall of the water-cooled roller 41.

[0037] Specifically, the communication pipes 411 at both ends of the same water-cooled roller 41 are respectively connected to the output end of the water pump and the cooling pool. After the water pump is turned on, the water pump draws cold water into the communication pipe 411, and the cold water flows through the gap between the water-cooled roller 41 and the filling cylinder 412, which can keep the water-cooled roller 41 in a low-temperature state. The filling cylinder 412 can make the cold water flow closer to the outer wall of the water-cooled roller 41, thereby ensuring the water cooling effect.

[0038] Further, the air-cooled assembly 3 is located between the composite film assembly 2 and the water-cooled assembly 4. The air-cooled assembly 3 includes two turning rods 31 and a plurality of upper guide rods 32 and a plurality of lower guide rods 33 located between the two turning rods 31. The upper guide rods 32 and the lower guide rods 33 are respectively located on both sides of the connecting line between the two turning rods 31. The upper guide rods 32 and the lower guide rods 33 are distributed in front of and behind the turning rods 31, and the turning rods 31, the upper guide rods 32 and the lower guide rods 33 are all rotatably connected between the two inner walls of the machine table 1.

[0039] Specifically, the upper guide rods 32 and the lower guide rods 33 are distributed in front of and behind the turning rods 31. This design helps the composite film to form a serpentine transmission path in the air-cooled assembly 3, which can increase the contact time between the composite film and the cold air, thereby improving the cooling efficiency. The turning rods 31, the upper guide rods 32 and the lower guide rods 33 are all installed between the two inner walls of the machine table 1 by means of rotary connection, which can reduce the resistance of the composite film transmission.

[0040] Further, a plurality of heat dissipation grooves 12 are formed on both sides of the machine table 1, and the heat dissipation grooves 12 are correspondingly arranged with the air-cooled assembly 3.

[0041] Specifically, the heat dissipation grooves 12 can effectively dissipate heat, which can avoid the rapid shrinkage of the composite film caused by direct low-temperature cooling, thereby ensuring the pressing quality of the composite film. It is worth noting that by arranging a fan at the position directly opposite the heat dissipation grooves 12, air can be forcibly introduced into the machine table 1, and the cold air can quickly flow around the composite film, thereby enhancing the heat dissipation efficiency.

[0042] Working principle:

[0043] In use, the two half membranes are rolled by the fixed roller 22 and the movable roller 26 to form a composite membrane, the composite membrane is transmitted in a serpentine shape between the upper guide rod 32 and the lower guide rod 33, heat can be dissipated outward through the heat dissipation groove 12, which can preliminarily cool the composite membrane, then the composite membrane passes through a plurality of water-cooled rollers 41 in turn, and cold water flows through the gap between the water-cooled roller 41 and the filling cylinder 412, which can keep the water-cooled roller 41 in a low temperature state, so that the water-cooled roller 41 can secondary cool the composite membrane, which fully guarantees the quality of the composite membrane.
