[0041] See also Figures 1 to 5 , this embodiment discloses a laminating device, comprising:

[0042] A first conveying unit 10, a film 80 folded in half covers the first conveying unit 10, and the opening of the film 80 faces the side of the first conveying unit 10;

[0043] A support plate 30, wherein the support plates 30 are two pieces, and the two support plates 30 are respectively placed on the upper and lower sides of the first conveying unit 10, and the support plates 30 are used to lift the film 80 away from the upper and lower surfaces of the first conveying unit 10;

[0044] A second conveying unit 20, wherein the input end of the second conveying unit 20 is disposed on one side of the output end of the first conveying unit 10 along the material conveying direction, and a cutting and sealing channel 70 is disposed between the input end of the second conveying unit 20 and the output end of the first conveying unit 10;

[0045] The cutting and sealing unit 40 is disposed in the sealing channel, and is used for cutting and sealing the film 80 passing through the cutting and sealing channel 70 .

[0046] The first conveying unit 10 is used to convey materials, and the film 80 is configured to cover the side of the first conveying unit 10, that is, the film 80 is a folded film 80, and the film 80 is divided into a first area and a second area along the fold, the first area is placed above the first conveying unit 10, the second area is placed below the first conveying unit 10, the fold is placed on one side of the first conveying unit 10, and the opening of the folded film 80 is placed on the other side of the first conveying unit 10.

[0047] There are two support plates 30, and the two support plates 30 are respectively placed on both sides of the upper and lower surfaces of the first conveying unit 10; the support plates 30 are used to lift the film 80 away from the upper and lower surfaces of the first conveying unit 10 to avoid the film 80 from being entangled with the first conveying unit 10; at the same time, the support plate 30 located above the first conveying unit 10 is lifted away from the film 80 to form a material channel, and the material channel is used for material to pass through.

[0048] It should be further explained that the support plate 30 may be lifted off the film 80 in the following two embodiments. First, the folded film 80 is always in accordance with Figure 1 The first conveying unit 10 is covered with the support plate 30, and the support plate 30 is placed between the film 80 and the first conveying unit 10 to lift the film 80. Second, the folded film 80 is placed on one side of the first conveying unit 10, and the opening of the film 80 is set toward the input end of the first conveying unit 10. At this time, the folded film 80 needs to be turned over to form Figure 1 state; at this time, the support plate 30 is used to flip and support the film 80.

[0049] The second conveying unit 20 is placed on one side of the output end of the first conveying unit 10 along the material transport direction, and there is a gap between the second conveying unit 20 and the first conveying unit 10, which is the cutting and sealing channel 70.
