[0027] The following is combined with Figure 1-2 The utility model is described in further detail.

[0028] The utility model discloses a self-adhesive waterproofing coiled material production system. Figure 1 , including a laminating frame 1, on which is installed a middle film driven unwinder 11, a bottom film side film driven unwinder 12, a surface film side film driven unwinder 13, a coating device 2, a cooling roller 3, a cooling composite pair of rollers 6, a cooling water tank 7, a chilled water spray device 8, a transmission roller 14 and a winding device 10, wherein the middle film driven unwinder 11 and the bottom film side film driven unwinder 12 are located on the same side of the laminating frame 1.

[0029] Reference Figure 1 , the coating equipment 2 is provided with multiple groups, and the multiple groups of coating equipment 2 are respectively installed on one side of the output end of the middle film drive unwinder 11, the bottom film side film drive unwinder 12 and the surface film side film drive unwinder 13, that is, the coating equipment 2 coats the surface of the coiled materials output by the middle film drive unwinder 11, the bottom film side film drive unwinder 12 and the surface film side film drive unwinder 13. Among them, the coiled materials output by the middle film drive unwinder 11 and the bottom film side film drive unwinder 12 are coated by the coating equipment 2 to complete the bonding.

[0030] Reference Figure 1 and Figure 2 The cooling composite pair of rollers 6 includes a first roller body 61 and a second roller body 62. The first roller body 61 is located at one side of the output end of the bottom film side film driving unwinding machine 12, that is, the first roller body 61 is used to transmit the coiled material transmitted by the bottom film side film driving unwinding machine 12, and the second roller body 62 is located at one side of the output end of the face film side film driving unwinding machine 13, that is, the second roller body 62 is used to transmit the coiled material transmitted by the face film side film driving unwinding machine 13. An extrusion gap for the coiled material to pass through is formed between the first roller body 61 and the second roller body 62, and the coiled material is bonded under the action of the first roller body 61 and the second roller body 62.

[0031] Reference Figure 1 , there are multiple groups of cooling rollers 3, and the multiple groups of cooling rollers 3 are respectively located at the coating end of each group of coating equipment 2, that is, the cooling rollers 3 are used to transmit the coiled materials, and the coating equipment 2 applies the coating to the surface of the coiled materials passing through the cooling rollers 3, wherein the cooling rollers 3 are jacketed cooling rollers with built-in spiral flow channels; the chilled water spraying equipment 8 is located on one side of the output end of the coating equipment 2, and the chilled water spraying equipment 8 sprays chilled water on the coiled materials after the coating is completed to cool the coiled materials. The coiled materials are quickly cooled during the transportation process, thereby reducing the shrinkage and deformation of the product due to high temperature, and ensuring that the film layers of various parts of the coiled materials are not deformed as a whole due to inconsistent thermal shrinkage or thermal deformation ratios.

[0032] Reference Figure 1In this embodiment, two groups of cooling water troughs 7 are provided, one group of cooling water troughs 7 is located near the middle film driving unwinder 11, and the other group of cooling water troughs 7 is located near the surface film side film driving unwinder 13, and the cooling rollers 3 located on one side of the middle film driving unwinder 11 and the bottom film side film driving unwinder 12 are partially immersed in the cooling water troughs 7, and the cooling rollers 3 located on one side of the surface film side film driving unwinder 13 are located above the cooling water troughs 7, so that the cooling rollers 3 maintain a lower temperature.

[0033] In other embodiments, the cooling roller 3 is connected to a lifting mechanism, so that the cooling roller 3 can switch between two states: partially immersed in the cooling water tank 7 or located above the cooling water in the cooling water tank 7. The lifting mechanism can be a hydraulic press, a manual lift, etc., which is not particularly limited here, and those skilled in the art can freely choose according to actual conditions.

[0034] Reference Figure 1 and Figure 2 In this embodiment, there are multiple groups of transmission rollers 14, which are distributed in the laminating machine frame 1. The transmission rollers 14 located on the output side of the cooling composite roller pair group 6 are set on the water surface and in the water of the cooling water tank 7. The staff can transfer the coiled material passing through the cooling composite roller pair group 6 to the transmission rollers 14 in the water or on the water surface of the cooling water tank 7 according to the type of waterproof coiled material produced. For example, when producing sand surface coiled materials, the coiled materials are transferred to the transmission rollers 14 on the water surface of the cooling water tank 7 to avoid damaging the sand surface; when producing double-sided laminating coiled materials, the coiled materials are transferred to the transmission rollers 14 in the water of the cooling water tank 7 so that the coiled materials are fully cooled. The winding device 10 is located at the outlet end of the cooling water tank 7, and the winding device 10 is used to receive the coiled materials transferred by the transmission rollers 14 on the water surface or in the water of the cooling water tank 7.

[0035] It is worth mentioning that when the coil is transferred to the transfer roller 14 in the cooling water tank 7, the lifting mechanism can be adjusted to adjust the cooling roller 3 located on one side of the mask edge film driving unwinding machine 13 to a state where part of the cooling water tank 7 is immersed. At this time, the cooling water tank 7 can not only cool the coil transferred in the water, but also cool the film unwound by the mask edge film driving unwinding machine 13, thereby improving the cooling efficiency and saving production costs.

[0036] Further, refer to Figure 1The laminating machine frame 1 is equipped with a tension detector 4, and there are multiple groups of tension detectors 4. The tension detectors 4 in this embodiment are optimally set to two groups, one group of tension detectors 4 is set on one side of the output end of the middle film drive unwinder 11 and the bottom film side film drive unwinder 12, and the other group of tension detectors 4 is set on one side of the output end of the surface film side film drive unwinder 13. Through the tension detector 4, the state of the coil itself during the conveying process can be detected in real time. According to the feedback result of the tension detector 4, the driving speed of the middle film drive unwinder 11, the bottom film side film drive unwinder 12, the surface film side film drive unwinder 13, the cooling roller 3, the cooling composite roller group 6 and the transmission roller 14 can be adjusted.

[0037] Further, refer to Figure 1 and Figure 2 The film coating frame 1 is provided with a sand coating device 5, which is located between the coating device 2 and the cooling composite roller pair group 6 at the output end of the middle film drive unwinder 11. A sand sweeping device 9 is provided on one side of the output end of the cooling composite roller pair. The sand sweeping device 9 cleans the sand surface of the coil and the roller body of the cooling composite roller pair group 6. When the self-adhesive coil produced is a sand surface coil, the sand coating device 5 sand coats the coil transmitted by the middle film drive unwinder 11. At this time, the face film side film drive unwinder 13 is in a shutdown state. After the coil passes through the cooling composite roller pair group 6, the excess sand particles are removed under the action of the sand sweeping device 9.

[0038] The implementation principle of a self-adhesive waterproof membrane production system in this embodiment:

[0039] The coating device 2 coats the coils output by the middle film driven unwinder 11, the bottom film side film driven unwinder 12 and the surface film side film driven unwinder 13, wherein after the coils output by the middle film driven unwinder 11 and the bottom film side film driven unwinder 12 are bonded, the coils are transmitted to the cooling composite roller group 6, and the coils output by the surface film side film driven unwinder 13 are transmitted to the cooling composite roller group 6, the coils are bonded and formed under the extrusion of the cooling composite roller group 6, and then transmitted to the winding device 10 through the transmission roller 14; the cooling roller 3 performs preliminary cooling of the coil, and the chilled water spray device 8 performs further cooling of the coil, and rapidly cools the coil during the coil conveying process to ensure that each layer is in a relatively low temperature state, thereby reducing the shrinkage and deformation of the coil due to high temperature, ensuring that the film layers at various parts do not cause overall deformation of the coil due to inconsistent thermal shrinkage or thermal deformation ratios, and the cooling water tank 7 can continuously play the function of cooling the product;

[0040] When producing products without intermediate polymer film base, the bottom film side film driven unwinding machine 12 and the surface film side film driven unwinding machine 13 can be started, and then the coating device 2 is used for coating and laminating once; when producing longitudinally overlapped mesh cloth products, the bottom film side film driven unwinding machine 12, the middle film driven unwinding machine 11 and the surface film side film driven unwinding machine 13 are coated and laminarized twice by the coating device 2, and then the complete coil is formed through the cooling composite roller group 6; when producing sand surface coil, the bottom film side film driven unwinding machine 12 and the middle film driven unwinding machine 11 are started, and after the sand coating device 5 completes the sand coating function, it passes through the cooling composite roller group and the sand sweeping device 9 to complete the production. The self-adhesive waterproof coil production system in this application realizes the production function of multiple types of waterproof coils.
