DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 3 As shown, the structure and function of a polyester composite waterproof membrane are described in detail below;

[0032] A polyester composite waterproof membrane comprises an upper surface protective layer 1, an intermediate base layer 2 and a lower surface waterproof layer 3, wherein the upper surface protective layer 1, the intermediate base layer 2 and the lower surface waterproof layer 3 are staggered and arranged on the side of the waterproof membrane to form a stepped surface;

[0033] When using, Figure 2 As shown, the upper surface protective layer 1, the middle tread base layer 2 and the lower surface waterproof layer 3 are staggered, so that the side of the waterproof membrane is formed into a stepped shape, as shown in FIG. Figure 3 As shown, when two waterproof membranes are laid, the steps on the sides of the two waterproof membranes interlock with each other, thereby increasing the contact area of ​​the two waterproof membranes, and due to the shape of the step surface, the waterproof effect is enhanced;

[0034] like Figures 4 to 11 As shown, in order to facilitate the processing of polyester composite waterproof membrane, a polyester composite waterproof membrane preparation device is designed. The structure and function of a polyester composite waterproof membrane preparation device are described in detail below;

[0035] A polyester composite waterproofing membrane preparation device includes a device support 41, two coiling mechanisms 7 are fixedly connected to the device support 41, two squeezing rollers I 52 are provided on the front side of the device support 41, two squeezing rollers II 62 are provided on the rear side of the device support 41, and a support mechanism 8 and a material spreading mechanism 9 are provided in the middle of the device support 41;

[0036] When using, Figure 4 As shown, the coiling mechanism 7 located at the lower side winds up the upper surface protective layer 1, and the coiling mechanism 7 located at the upper side winds up the intermediate tread base layer 2. The upper surface protective layer 1 and the intermediate tread base layer 2 have the same width and are offset by a certain distance. The upper surface protective layer 1 and the intermediate tread base layer 2 are driven by two squeezing rollers I 52 to pass between the support mechanism 8 and the spreading mechanism 9. The support mechanism 8 supports the empty area between the upper surface protective layer 1 and the intermediate tread base layer 2. The spreading mechanism 9 applies the lower surface waterproof layer 3 to the intermediate tread base layer 2 and discharges the layer from the two squeezing rollers II 62, thereby forming a waterproof coiled material with stepped side edges.

[0037] The upper surface protective layer 1 is a PE film, the middle tread base layer 2 is a polyester non-woven fabric / polyester felt, and the lower surface waterproof layer 3 is SBS / APP modified asphalt;

[0038] like Figure 6 As shown, in order to adapt to the upper surface protection layer 1 and the intermediate tire base layer 2 of different thicknesses, the structure and function of the squeezing roller I 52 and the squeezing roller II 62 are described in detail below;

[0039] The front end of the device bracket 41 is fixedly connected to two telescopic mechanisms I51, and two squeezing rollers I52 are rotatably connected to the telescopic ends of the two telescopic mechanisms I51 respectively; the telescopic ends of the telescopic mechanisms I51 are fixedly connected to servo motors that drive the squeezing rollers I52 to rotate;

[0040] The rear end of the device bracket 41 is fixedly connected to two telescopic mechanisms II 61, and two squeezing rollers II 62 are rotatably connected to the telescopic ends of the two telescopic mechanisms II 61; the telescopic ends of the telescopic mechanisms II 61 are fixedly connected to servo motors that drive the squeezing rollers II 62 to rotate;

[0041] The telescopic mechanism I51 is activated. The telescopic mechanism I51 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I51 drives the squeezing roller I52 to move, thereby adjusting the relative distance between the two squeezing rollers I52 so that the two squeezing rollers I52 can be used for upper surface protective layers 1 and intermediate tire base layers 2 of different thicknesses.

[0042] The telescopic mechanism II 61 is activated. The telescopic mechanism II 61 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 61 drives the squeezing roller II 62 to move, thereby adjusting the relative distance between the two squeezing rollers II 62 so that the squeezing rollers II 622 can be used for the upper surface protective layer 1, the middle tread base layer 2, and the lower surface waterproof layer 3 of different thicknesses.

[0043] like Figure 7 As shown, in order to enable the upper surface protective layer 1 and the intermediate tire base layer 2 to be staggered, the structure and function of the coiling mechanism 7 are described in detail below;

[0044] The coiling mechanism 7 includes an adjusting bracket 71, which is fixedly connected to the device bracket 41, a screw rod 72 being rotatably connected to the adjusting bracket 71, a power mechanism for driving the screw rod 72 to rotate being fixedly connected to the adjusting bracket 71, a coiling bracket 73 being slidably connected to the adjusting bracket 71, the coiling bracket 73 being connected to the screw rod 72 by a thread, and two telescopic mechanisms III 74 being fixedly connected to the coiling bracket 73, the telescopic ends of the two telescopic mechanisms III 74 being rotatably connected to conical wheels 75, and a coiling drum 76 being clamped between the two conical wheels 75;

[0045] When in use, the roll 76 with the upper surface protective layer 1 wound on it is placed between the two conical wheels 75 located on the lower side, and the telescopic mechanism III 74 is started. The telescopic mechanism III 74 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 74 drives the conical wheels 75 to move closer to each other, so that the two conical wheels 75 clamp the roll 76;

[0046] The coil 76 with the intermediate tire base layer 2 wound on it is placed between the two tapered wheels 75 on the upper side, and the telescopic mechanism III 74 is activated. The telescopic mechanism III 74 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 74 drives the tapered wheels 75 to move closer to each other, so that the two tapered wheels 75 clamp the coil 76.

[0047] The power mechanism is started. The power mechanism is preferably a servo motor. The output shaft of the power mechanism drives the screw 72 to rotate. When the screw 72 rotates, the coil holder 73 is driven by the thread to move laterally. The coil holder 73 drives the coil drum 76 to move laterally. The coil drum 76 drives the corresponding upper surface protective layer 1 or the intermediate tread base layer 2 to move, so that the upper surface protective layer 1 and the intermediate tread base layer 2 are offset to a certain extent.

[0048] like Figure 8 As shown, the upper surface protective layer 1 and the intermediate tread base layer 2 are misaligned. To ensure the quality of molding, it is necessary to support the bottom of the upper surface protective layer 1 and the portion of the intermediate tread base layer 2 that is vacant relative to the upper surface protective layer 1. The structure and function of the support mechanism 8 are described in detail below.

[0049] The support mechanism 8 includes a telescopic mechanism IV 81, which is fixedly connected to the device bracket 41. The telescopic end of the telescopic mechanism IV 81 is fixedly connected to a telescopic mechanism V 82, and the telescopic end of the telescopic mechanism V 82 is fixedly connected to a mounting plate 83. The mounting plate 83 is fixedly connected to multiple telescopic mechanisms VI 84, and each telescopic end of the telescopic mechanism VI 84 is fixedly connected to a support cavity 85. The multiple support cavities 85 are arranged side by side.

[0050] The support cavity 85 is hollow, and a cooling water pipe 86 is fixedly connected to the support cavity 85;

[0051] The telescopic mechanism IV 81 and the telescopic mechanism V 82 are activated. The telescopic mechanism IV 81 and the telescopic mechanism V 82 may be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism IV 81 drives the telescopic mechanism V 82 to move up and down. The telescopic end of the telescopic mechanism V 82 drives the mounting plate 83 to move laterally, thereby adjusting the height and lateral position of the mounting plate 83. The mounting plate 83 drives the multiple supporting cavities 85 to move, thereby adjusting the height and lateral position of the multiple supporting cavities 85.

[0052] Furthermore, according to the empty position of the intermediate tread base layer 2, the corresponding telescopic mechanism VI84 is activated. The telescopic mechanism VI84 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VI84 drives the support cavity 85 to move, so that the support cavity 85 supports the empty portion of the intermediate tread base layer 2. This ensures that when the lower surface waterproof layer 3 is subsequently applied, the deformation of the intermediate tread base layer 2 will not cause deformation of the lower surface waterproof layer 3.

[0053] Furthermore, since the lower surface waterproof layer 3 also needs to be partially offset relative to the intermediate tread base layer 2, the telescopic mechanism VI 84 at the corresponding position is activated. The telescopic end of the telescopic mechanism VI 84 drives the support cavity 85 to move, so that the support cavity 85 supports the portion of the lower surface waterproof layer 3 that is offset relative to the intermediate tread base layer 2.

[0054] Furthermore, in order to quickly shape the lower surface waterproof layer 3, a cooling water pipe 86 is connected to the cooling water pipeline so that cooling water can continuously pass through the support cavity 85. The support cavity 85 quickly cools and shapes the lower surface waterproof layer 3 applied thereon, so that the lower surface waterproof layer 3 can be shaped and pass between the two squeezing rollers II 62.

[0055] The structure and function of the material laying mechanism 9 are described in detail below;

[0056] The material spreading mechanism 9 includes a telescopic mechanism VII 91, which is fixedly connected to the device bracket 41. The telescopic end of the telescopic mechanism VII 91 is fixedly connected to a telescopic mechanism VIII 92, and the telescopic end of the telescopic mechanism VIII 92 is fixedly connected to a material spreading box 93. The upper and lower ends of the material spreading box 93 are both open.

[0057] The side of the material spreading box 93 is fixedly connected to the electric push rod 94, and the telescopic end of the electric push rod 94 is fixedly connected to the limit plate 95, and the limit plate 95 is slidably connected in the material spreading box 93;

[0058] When in use, pour SBS / APP modified asphalt between the two limit plates 95 in the paving box 93, and according to the width of the lower surface waterproof layer 3 that needs to be processed in advance, start the electric push rod 94, and the telescopic end of the electric push rod 94 drives the limit plate 95 to move, so that the limit plate 95 slides in the paving box 93, thereby adjusting the size of the bottom opening of the paving box 93, and then adjusting the width of the lower surface waterproof layer 3;

[0059] Furthermore, the position of the lower surface waterproof layer 3 is processed in advance as needed, and the telescopic mechanism VII 91 and the telescopic mechanism VIII 92 are activated. The telescopic mechanism VII 91 and the telescopic mechanism VIII 92 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism VII 91 drives the paving box 93 to move up and down, thereby adjusting the height of the paving box 93. The telescopic end of the telescopic mechanism VIII 92 drives the paving box 93 to move laterally, thereby adjusting the position of the paving box 93 for processing and forming the lower surface waterproof layer 3.

[0060] A method for preparing a polyester composite waterproof roll, the method comprising the following steps:

[0061] Step 1: The coiling mechanism 7 on the lower side winds up the upper surface protective layer 1, and the coiling mechanism 7 on the upper side winds up the intermediate tread base layer 2. The upper surface protective layer 1 and the intermediate tread base layer 2 have the same width and are offset by a certain distance. The upper surface protective layer 1 and the intermediate tread base layer 2 are driven by two squeezing rollers I 52 to pass between the support mechanism 8 and the paving mechanism 9.

[0062] Step 2: The supporting mechanism 8 supports the vacant areas of the upper surface protective layer 1 and the middle tread base layer 2, and the spreading mechanism 9 applies the lower surface waterproof layer 3 to the middle tread base layer 2, and discharges it from the two squeezing rollers II 62, thereby forming a waterproof roll with stepped side edges.
