[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The following is combined with Figure 1 Detailed description, a method for preparing a polyester composite waterproof roll material, the preparation method comprising the following steps:

[0033] Step 1: Place water and polyester in a heating dish in proportion to prepare a polyester solution;

[0034] Step 2: placing the prepared asphalt block into a flaking device to complete the processing of the block asphalt into flaked asphalt;

[0035] Step 3: Add the polyester solution into the coating device, and then let the sheet of asphalt pass through the coating device to coat the polyester solution on both sides of the sheet of asphalt;

[0036] Step 4: Dry the flaky asphalt and collect it on a roller to complete the preparation of the polyester composite waterproof membrane.

[0037] The following is combined with Figure 1 In detail, the sheet-making device is capable of processing sheet-shaped asphalt with different thicknesses and widths.

[0038] Furthermore, the position of the flaking device can be adjusted to achieve the processing of asphalt flakes of different thicknesses and widths. The flaking device can be adjusted according to the needs of the place of use to process asphalt flakes of required thickness and width.

[0039] The following is combined with Figure 2-5 In detail, the film making device includes a hot melt chamber 101, two rotating shafts 102, two spiral plates 103, four sliding adjustment plates 104, four adjusting screws 105 and two extrusion rollers 106. The hot melt chamber 101 is rotatably connected to the two rotating shafts 102 through an axis, the two spiral plates 103 are respectively fixedly connected to the two rotating shafts 102 by welding, the four sliding adjustment plates 104 are all slidably connected to the hot melt chamber 101 through empty grooves, the four adjusting screws 105 are all rotatably connected to the hot melt chamber 101 through bearing seats, the four adjusting screws 105 are respectively connected to the four sliding adjustment plates 104 by threaded transmission, and the two extrusion rollers 106 are respectively rotatably connected to the two horizontally located adjusting screws 105 through bearing seats.

[0040] Furthermore, an addition port is provided above the hot melt chamber 101, and block asphalt is placed into the hot melt chamber 101 by means of the addition port. A heating plate is provided at the bottom of the hot melt chamber 101, and the heat generated by the heating plate is used to act on the block asphalt to convert the block asphalt into liquid asphalt. An inclined discharge port is provided below the hot melt chamber 101, and when the liquid asphalt is discharged from the inclined discharge port below the hot melt chamber 101, the processing of the flaky asphalt can be completed, and the two rotating shafts 102 can drive the two spiral plates 103 to rotate. When the two spiral plates 103 rotate, the stirring process of the liquid asphalt in the hot melt chamber 101 can be completed, and the two spiral plates 103 have opposite rotation directions. When the two spiral plates 103 rotate, a reverse driving force will be generated, allowing the liquid asphalt on the left and right sides of the hot melt chamber 101 to move forward and backward on one side, so that the liquid asphalt in the hot melt chamber 101 forms a cycle. The four adjusting screws 105 can be rotated to drive the four sliding plates 104 to slide, thereby changing the positions of the four sliding plates 104. In this way, the opening formed by the four sliding plates 104 will change, so that the thickness and width of the asphalt can be changed. The four sliding plates 104 are provided with scales for convenient observation of the positions of the four sliding plates 104, thereby changing the thickness and width of the processed flaky asphalt. The distance between the two lateral sliding plates 104 can change the thickness of the processed flaky asphalt. After two rotating rollers 106 are provided, the surface of the flaky asphalt can be further rolled to ensure that the surface of the flaky asphalt is smooth. A valve is provided under the hot melt chamber 101. Only when the block asphalt in the hot melt chamber 101 becomes liquid asphalt, the valve is opened to allow the liquid asphalt in the hot melt chamber 101 to be discharged, thereby realizing the processing of the liquid material into flaky asphalt.

[0041] According to the instruction manual Figure 2 , 3 5 is described in detail, the film making device also includes a ladle inverted shaft 201, two convex stirring plates 202 and two pouring troughs 203, the ladle inverted shaft 201 is connected to the hot melt chamber 101 by shaft rotation, the two convex stirring plates 202 are mirror-imaged and fixedly connected to the ladle inverted shaft 201 by welding, and the two pouring troughs 203 are respectively arranged on the two convex stirring plates 202.

[0042] Furthermore, the dipper shaft 201 can drive the two convex stirring plates 202 to rotate, and the rotating two convex stirring plates 202 can drive the two pouring troughs 203 to rotate. The dipper shaft 201 is connected to the two rotating shafts 102 through a transmission chain. A reduction motor I is fixedly connected to the hot melt chamber 101, and the output shaft of the reduction motor I is fixedly connected to the dipper shaft 201 through a coupling. Starting the reduction motor I can drive the dipper shaft 201 to rotate, and the rotating dipper shaft 201 can drive the two rotating shafts 102 to rotate through the transmission chain. When the asphalt is stirred by the two spiral plates 103, the two pouring troughs 203 will also rotate. When the two pouring troughs 203 rotate, the two pouring troughs 203 can drive the liquid asphalt located at the bottom of the hot melt chamber 101 to move upward, thereby enhancing the flow range of the liquid asphalt in the hot melt chamber 101, further enhancing the stirring effect of the liquid asphalt in the hot melt chamber 101, and ensuring that the asphalt can be evenly heated.

[0043] According to the instruction manual Figure 2-4 In detail, the tablet making device also includes a grinding block component and a hot filter curved plate 304. The grinding block component is fixedly connected to the hot melt chamber 101 by welding, and the hot filter curved plate 304 is fixedly connected to the hot melt chamber 101 by welding.

[0044] Furthermore, large pieces of asphalt can be placed in the grinding block component to convert the large pieces of asphalt into small pieces of asphalt. The small pieces of asphalt will fall onto the hot filter plate 304, which is provided with multiple filter holes and has a heating function. The heating function of the hot filter plate 304 is used to heat the small pieces of asphalt to further reduce the diameter of the small pieces of asphalt. When the diameter is small enough, it will fall from the hot filter plate 304 into the hot melt chamber 101, which can accelerate the melting rate of the asphalt in the hot melt chamber 101.

[0045] According to the instruction manual Figure 2 , 3 6 describes in detail that the grinding block component includes a cutting block cavity 301, two grinding block rollers 302 and two gears 303. The cutting block cavity 301 is fixedly connected to the hot melt cavity 101 by welding, and the two grinding block rollers 302 are both connected to the cutting block cavity 301 by shaft rotation. The two gears 303 are fixedly connected to the two grinding block rollers 302 by welding, and the two gears 303 are meshed and transmitted.

[0046] Furthermore, large pieces of asphalt are cut in the cutting chamber 301. When the large piece of asphalt is located between the two grinding rollers 302, the cutting of the large piece of asphalt can be completed. Both grinding rollers 302 are provided with multiple protrusions and multiple grooves, which cooperate with each other. A reduction motor II is fixedly connected to the cutting chamber 301. The output shaft of the reduction motor II is fixedly connected to one of the grinding rollers 302 through a coupling. After starting the reduction motor II, the grinding roller 302 connected thereto can be driven to rotate. The rotating grinding roller 302 is connected through the meshing transmission between the two gears 303 to drive the other grinding roller 302 to rotate, so that the two grinding rollers 302 rotate inward at the same time, so that the large piece of asphalt can be cut.

[0047] According to the instruction manual Figure 2 and 3 In detail, the film making device also includes two inclined slide plates 305, and the two inclined slide plates 305 are fixedly connected in the cutting cavity 301 by welding.

[0048] Further, such as Figure 1 and 2 It can be seen that the two inclined slide plates 305 are both inclined inward, so asphalt can be placed between the two inclined slide plates 305, allowing large pieces of asphalt to fall between the two grinding rollers 302, and the asphalt can be cut into pieces by the rotation of the two grinding rollers 302.

[0049] According to the instruction manual Figure 2-4 As described in detail in 8-9, the film making device also includes two fixed support plates 401, a cooling chamber 402, an isolation plate 403 and a separation roller 404. The two fixed support plates 401 are fixedly connected to the hot melt chamber 101 by welding, the cooling chamber 402 and the two fixed support plates 401 are fixedly connected by welding, the hot melt chamber 101 is in contact with the cooling chamber 402, the isolation plate 403 is fixedly connected in the cooling chamber 402 by welding, and the separation roller 404 is rotatably connected to the cooling chamber 402 through a bearing.

[0050] Furthermore, the two fixed support plates 401 can provide a fixed space for the cooling chamber 402, store cold water in the cooling chamber 402, and use the isolation plate 403 to divide the cooling chamber 402 into two spaces. The two spaces in the cooling chamber 402 do not affect each other. When the liquid asphalt is discharged from the hot melt chamber 101, it will directly fall into the cooling chamber 402, allowing the discharged flaky asphalt to contact the left and right ends of the separation roller 404. In this way, the moving position of the flaky asphalt discharged from the hot melt chamber 101 can be changed. The flaky asphalt can be first allowed to enter the left end of the cooling chamber 402. When the flaky asphalt is in the empty space at the left end of the cooling chamber 402, the flaky asphalt can be moved to the left end of the cooling chamber 402. When the asphalt sheet moves in the space at the left end of the cooling chamber 402, the cooling treatment of the asphalt sheet can be achieved. Only after the asphalt sheet is cooled can the polyester solution be applied to the asphalt sheet. After the asphalt sheet moves in the space at the left end of the cooling chamber 402 for a period of time, the water in the space at the left end of the cooling chamber 402 will heat up, and the cooling effect on the asphalt sheet will be reduced. At this time, the position of the asphalt sheet can be changed, so that the asphalt sheet can contact the right end of the separation roller 404, the asphalt sheet can enter the right end of the cooling chamber 402, and the asphalt sheet can move in the space at the right end of the cooling chamber 402. This can ensure that the asphalt sheet is in contact with cold water.

[0051] According to the instruction manual Figure 5 , 6 , 9 and 10 illustrate in detail that the film making device also includes two belt-moving components, and both belt-moving components are connected to the cooling chamber 402.

[0052] Furthermore, after the asphalt sheet is cooled, it is necessary to move the asphalt sheet. At this time, the asphalt sheet can be brought into contact with a belt-moving component, and the belt-moving component can be rotated to move the asphalt sheet, thereby allowing the asphalt sheet to quickly leave the cooling chamber 402.

[0053] The belt-shifting component includes a central axis 501, a transfer arm 502, a transfer roller 503, a worm gear 601 and a main rotating wheel 602. There are four central axes 501, and the four central axes 501 are rotatably connected to the transfer arms 502 via bearings. Two transfer rollers 503 are rotatably connected between the four transfer arms 502 via shafts. The four transfer arms 502 are respectively meshed and transmission-connected with the two worm gears 601. The main rotating wheel 602 is transmission-connected to the two worm gears 601 via a transmission chain. Two groups of four central axes 501 are fixedly connected to the cooling chamber 402 by welding. Two groups of two worm gears 601 are fixedly connected to the cooling chamber 402 by welding. The two main rotating wheels 602 are rotationally connected to the two sides of the cooling chamber 402 via shafts and holes, respectively.

[0054] Furthermore, the central shaft 501 can provide a rotation space for the transfer arm 502, and a worm gear is arranged below the transfer arm 502. The transfer arm 502 can provide a rotation space for the transfer roller 503. The four transfer arms 502 at the front end are fixedly connected with a reduction motor III. The output shafts of the four reduction motors III are respectively fixedly connected to the four transfer rollers 503 through a coupling. The four reduction motors III are connected to the power line through the same wire and switch. The four reduction motors III will be started at the same time. After starting the four reduction motors III, the four transfer rollers 50 3 is rotated, and the rotating four transfer rollers 503 will drive the flaky asphalt to move, so as to discharge the flaky asphalt quickly from the cooling chamber 402. After the main rotating wheel 602 is rotated, the two worm gears 601 can be driven to rotate, and the rotating two worm gears 601 will drive the four transfer arms 502 to rotate, so that the four transfer arms 502 move inward or outward at the same time, thereby changing the distance between the four transfer rollers 503, so that the flaky asphalt can contact the four transfer rollers 503 at the same time. In this way, when the four transfer rollers 503 rotate, the flaky asphalt can be driven to move.
