[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1As shown, a device for coating glue on the back of a waterproof coiled material comprises a first unwinding mechanism, a coating mechanism and a pressing mechanism which are sequentially arranged along the forward direction of a first isolation film 20, and a waterproof coiled material conveying mechanism is further provided, wherein the waterproof coiled material conveying mechanism comprises a plurality of guide rollers, and the waterproof coiled material 19 has completed single-sided coating glue and lamination before entering the waterproof coiled material conveying mechanism, and the waterproof coiled material 19 which has completed single-sided coating glue and lamination passes through a plurality of guide rollers in sequence and enters the pressing mechanism, and is pressed together with the first isolation film 20 which has passed through the coating mechanism, wherein the first isolation film 20 is a single silicone oil release film; the coating mechanism comprises a frame 1, a cooling roller 2 and a coating mold 3, wherein the frame 1 is fixedly arranged on the ground, the cooling roller 2 is rotatably arranged on the frame 1, the coating mold 3 is slidably arranged on the frame 1, and the first isolation film 20 is located between the cooling roller 2 and the coating mold 3. In the utility model, the first isolation film 20 to be coated with glue is wound on the first unwinding mechanism. After being unwound by the first unwinding mechanism, the first isolation film 20 is transported between the glue coating mold 3 and the cooling roller 2. Glue is transported in the glue coating mold 3. After the glue passes through the glue coating mold 3, it is smeared on the first isolation film 20. The cooling roller 2 can cool and shape the glue on the first isolation film 20 to prevent the glue from flowing on the first isolation film 20. The first isolation film 20 coated with glue is transported to the pressing mechanism and pressed together with the waterproof roll 19 that has been coated with glue on one side. Since the first isolation film 20 is a single silicone oil release film, glue is not easy to adhere to the first isolation film 20. Therefore, when the side of the first isolation film 20 coated with glue is pressed against the back side of the waterproof roll 19, the glue is transferred to the waterproof roll 19 and adheres to the waterproof roll 19, so that the back side of the waterproof roll 19 is coated with glue.

[0023] It should be noted that the glue coating mold 3 is a rectangular box-shaped structure, a cavity is provided inside the glue coating mold 3, a glue outlet gap is provided on the glue coating mold 3, and a glue feeding tube is connected to the glue coating mold 3. The glue enters the internal cavity of the glue coating mold 3 through the glue feeding tube, and is squeezed out from the glue outlet gap and smeared on the first isolation membrane 20.

The glue coating mold 3 is fixedly provided on the mounting block 5. In this embodiment, a driving cylinder is also provided on the frame 1, and the piston rod of the driving cylinder is fixedly connected to the mounting block 5. When the first isolation membrane 20 needs to be replaced, the piston rod of the driving cylinder can be extended to drive the mounting block 4 to slide along the slide rail 4 toward the side away from the cooling roller 2, thereby driving the glue coating mold 3 to move toward the side away from the cooling roller 2, so that the gap between the glue coating mold 3 and the cooling roller 2 is increased, which is convenient for replacing the first isolation membrane 20. After the first isolation membrane 20 is replaced, the piston rod of the driving cylinder is retracted, so that the gap between the glue coating mold 3 and the cooling roller 2 is reduced, which is convenient for gluing the first isolation membrane 20.

[0025] In another embodiment, the first unwinding mechanism includes an unwinding vehicle 6 and a first unwinding roller 7, the unwinding vehicle 6 is arranged on the ground, the first unwinding roller 7 is rotatably arranged on the unwinding vehicle 6, and the first isolation film 20 is wound on the first unwinding roller 7. In this embodiment, a track is fixedly arranged on the ground, the track is a channel steel, a roller is arranged at the bottom of the unwinding vehicle 6, the roller is located on the track, and the unwinding vehicle 6 can move along the track.

[0026] In another embodiment, the first unwinding mechanism is provided with two groups, one of the two groups of the first unwinding mechanisms is a spare group, and when the first isolation film 20 of one group of the first unwinding mechanisms is used up, the first isolation film 20 in the spare group can be quickly replaced to reduce downtime.

[0027] In another embodiment, a flattening roller 8 is provided between the unwinding vehicle 6 and the gluing mechanism to make the first isolation film 20 flat and smooth during transportation, thereby preventing the first isolation film 20 from wrinkling.

[0028] like Figure 2 As shown, in another embodiment, a correction component is provided between the unwinding trolley 6 and the gluing mechanism, and the correction component includes a correction cylinder 9 and a connecting plate 10. The correction cylinder 9 is fixedly arranged on the ground, one end of the connecting plate 10 is fixedly connected to the piston rod of the correction cylinder 9, and the other end is fixedly connected to the unwinding trolley 6. In this embodiment, in order to prevent the first isolation film 20 from deflecting during the conveying process, a correction component is provided for correction. An infrared sensor is fixedly provided on the ground for detecting the conveying position of the first isolation film 20. When the infrared sensor detects that the first isolation film 20 is offset, the piston rod of the correction cylinder 9 is retracted and drives the connecting plate 10 to move. The connecting plate 10 drives the unwinding trolley 6 to move along the track, so that the first isolation film 20 is returned to the center, thereby achieving correction.

The pressed waterproof coiled material 19 is double-sidedly coated with adhesive and can then be rolled up and stored. At the same time, since the first supporting roller 12 and the second supporting roller 15 will not move up and down, when the first isolation film 20 and the waterproof coiled material 19 are replaced, the first pressing roller 13 and the second pressing roller 16 are moved up, and the first isolation film 20 and the waterproof coiled material 19 are laminated together and then laid flat on the first supporting roller 12 and the second supporting roller 15.
