Detailed Implementation

[0027] refer to Figure 1 , 2 Section 3 details the method and process for preparing plastomer-modified asphalt:

[0028] A method for preparing plastinated modified asphalt, the method comprising the following steps:

[0029] Step 1: Heat the asphalt raw material and add modifiers for mixing. Heating the raw material can enhance its fluidity, making it easier to mix various raw materials and modifiers, and can better mold the asphalt to produce the desired plastic modified asphalt.

[0030] Step 2: Drill holes in the substrate to increase its plasticity. After drilling, apply the asphalt obtained from the mixture in Step 1 to both sides of the substrate so that both sides of the substrate are covered with asphalt.

[0031] Step 3: Level and discharge the asphalt-covered substrate. Level the substrate and the asphalt on both sides to make the two surfaces of the asphalt smoother. At the same time, the presence of the substrate increases the plasticity of the asphalt, which can be processed into the required shape. One of the main uses of asphalt is waterproofing. Asphalt is also often used as waterproof membrane. When waterproofing objects with uneven corrugations is required, conventional operations cannot cover them properly. However, by stamping the asphalt into a corrugated shape, it can perfectly fit the uneven corrugated object and provide good waterproofing. By shaping the substrate, the purpose of shaping the asphalt is achieved, thereby processing plastic body modified asphalt.

[0032] Step 4: Collect the prepared asphalt.

[0033] In conjunction with the above embodiments, the following functions can also be achieved;

[0034] refer to Figure 4 The detailed process of pressing leveled asphalt into a corrugated shape is explained below:

[0035] The device includes a frame 31, on which an upper frame 11 and a lower frame 21 are slidably connected. Both the upper frame 11 and the lower frame 21 are provided with multiple arc-shaped protrusions, which are staggered and arranged opposite to each other. Asphalt covering both sides of the substrate passes through the middle of the upper frame 11 and the lower frame 21 for transportation. When the asphalt passes through the middle of the upper frame 11 and the lower frame 21, the upper frame 11 and the lower frame 21 are repeatedly slid relative to each other by external force to press the asphalt, and then move away from each other synchronously to prepare for the next pressing. By repeatedly pressing the asphalt, the asphalt is processed into a corrugated shape to prepare plastic modified asphalt.

[0036] In conjunction with the above embodiments, the following functions can also be achieved;

[0037] refer to Figure 4 , 5 Sections 6 and 7 detail the process by which the guiding upper and lower frame movements complete the pressing of the asphalt:

[0038] Multiple sliding tubes I12 are bolted to the upper frame 11. These sliding tubes I12 reduce friction between the upper frame 11 and the upright frame 31. Lubricant is applied to the inner walls of the sliding tubes I12 for lubrication, further reducing friction. Multiple sliding tubes II22 are bolted to the lower frame 21. These sliding tubes II22 also reduce friction between the lower frame 21 and the upright frame 31. Lubricant is applied to the inner walls of the sliding tubes II22 for lubrication, further reducing friction. This reduces frictional wear on the upright frame 31 and extends the service life of the parts. At the same time, precise guidance of the upper frame 11 and the lower frame 21 ensures that their positions correspond and do not change. While driving the upper frame 11 and the lower frame 21 to move synchronously, the asphalt can be pressed.

[0039] In conjunction with the above embodiments, the following functions can also be achieved;

[0040] refer to Figure 4 , 5 Sections 6 and 8 detail the implementation process of driving the synchronous reverse movement of loading and unloading:

[0041] Both ends of the upper frame 11 are bolted to two lead screw sleeves I 13, and both ends of the lower frame 21 are bolted to lead screw sleeves II 23. Two lead screws 41 are rotatably connected to the upright frame 31 via bearings. Each lead screw 41 is bolted to the output shaft of its corresponding geared motor I. Both geared motors I are bolted to the upright frame 31. The two lead screws 41 drive their respective lead screw sleeves I 13 and II 23, respectively, activating the two geared motors I. The two geared motors I drive... The two lead screws 41 rotate, and the two lead screws 41 drive the corresponding lead screw sleeves II 23 through the threads. The lead screw sleeves II 23 are raised and lowered under the guidance of the upright frame 31 on the upper frame 11 and the lower frame 21, thereby driving the upper frame 11 and the lower frame 21 to move closer to each other synchronously to complete the asphalt pressing. It can also make the upper frame 11 and the lower frame 21 move away from each other synchronously to prepare for the next asphalt pressing. The asphalt transportation is intermittent, which can give the upper frame 11 and the lower frame 21 ample preparation time and pressing time to ensure that qualified corrugated asphalt is processed.

[0042] In conjunction with the above embodiments, the following functions can also be achieved;

[0043] refer to Figure 7 and 8 The detailed process for ensuring the spacing between the upper and lower frames during asphalt stamping is as follows:

[0044] Each lead screw 41 is fixedly connected to a spacer block 42 in the middle. The axial length of the spacer block 42 can determine the minimum distance between the upper frame 11 and the lower frame 21, thereby controlling the stamping interval of the asphalt. The multiple spacers 42 are made of elastic material, which buffers the lead screw sleeves I13 and II23 while moving and stopping them.

[0045] In conjunction with the above embodiments, the following functions can also be achieved;

[0046] refer to Figure 8 The following details the implementation process of driving the corresponding synchronous reverse movement of loading and unloading:

[0047] The threads at both ends of the lead screw 41 have opposite directions of rotation. Thus, when the lead screw 41 rotates, the corresponding lead screw sleeves I13 and II23 are driven to slide in opposite directions synchronously through the different thread directions, thereby realizing the stamping process of asphalt by the upper frame 11 and the lower frame 21.

[0048] In conjunction with the above embodiments, the following functions can also be achieved;

[0049] refer to Figure 8 This section details the process of supporting the pressed asphalt:

[0050] Two base frames 51 are fixedly connected to one side of the upright frame 31. Each base frame 51 is slidably connected to a slide rod 52. Each slide rod 52 is fixedly connected to a support block 53 at its upper end. Each slide rod 52 is fixedly connected to a spring between itself and the corresponding base frame 51. The support blocks 53 on both sides support the two sides of the asphalt. The two support blocks 53 support the concave part of the corrugated asphalt when viewed from the bottom up. When the asphalt moves, the convex part of the moving asphalt presses down on the support block 53, and simultaneously presses down on the corresponding spring. When the concave part presses down on the support block 53 again, the compressed spring bounces back up when it returns to its original position and falls back into the concave part of the asphalt, thus supporting the asphalt.

[0051] In conjunction with the above embodiments, the following functions can also be achieved;

[0052] refer to Figure 9 and 10 The following details the process of supporting unpressed asphalt:

[0053] A bracket 61 is fixedly connected to the other side of the support frame 31. Multiple rollers 62 are rotatably connected to the bracket 61 via bearings. The rollers 62 on the bracket 61 are divided into two groups. Each group of rollers 62 rubs against each other for transmission. Asphalt is laid on the rollers 62. When the rollers 62 are driven by external force, they rotate. The rollers 62 rotate synchronously, supporting the asphalt while grinding the lower surface of the asphalt, which can remove the protrusions on the asphalt surface.

[0054] In conjunction with the above embodiments, the following functions can also be achieved;

[0055] refer to Figure 10 , 11 Section 12 details the implementation process of clamping the two sides of the asphalt:

[0056] Both ends of the bracket 61 are rotatably connected to clamping frames 63, and clamping wheels 64 are rotatably connected to the two clamping frames 63. A tension spring 65 is fixedly connected between the two clamping frames 63. Under the pull of the tension spring 65, the two clamping frames 63 rotate, and the two clamping frames 63 drive the two clamping wheels 64 to clamp the two sides of the asphalt, assisting the asphalt to be transported smoothly. During the asphalt transportation process, the asphalt drives the two clamping wheels 64 to rotate.

[0057] In conjunction with the above embodiments, the following functions can also be achieved;

[0058] refer to Figure 11 and 12 The following details the implementation process of using asphalt transportation to drive the rotation of multiple support rollers:

[0059] Each of the two clamping wheels 64 is fixedly connected to a driving wheel 71, and each of the two outermost support wheels 62 is fixedly connected to a driven wheel 72. The two driving wheels 71 mesh with the corresponding driven wheels 72 for transmission. When the two clamping wheels 64 rotate, the two clamping wheels 64 drive the two driving wheels 71 to rotate. The two driving wheels 71 mesh with and drive the two driven wheels 72 to rotate. The two driven wheels 72 drive the two outer support wheels 62 to rotate. At the same time as the two outer support wheels 62 rotate, friction drives the remaining multiple support wheels 62 to rotate, thereby polishing the supported asphalt.
