[0002] Choose waterproofing membranes that are suitable for the roofing environment and requirements, such as SBS, APP and other materials, remove debris, dust and oil on the roof, and ensure that the base is flat, clean, without damage and cracks. If necessary, repair the base and apply a layer of base treatment agent on the base to enhance the bonding between the membrane and the base. After the base treatment agent is dry, proceed to the next step of construction. Usually, the rolled membrane is unrolled and laid on the roof, and construction equipment is used for auxiliary construction.

[0037] The moving mechanism 100 includes a moving frame 101 and a pressing roller group arranged at the bottom of the moving frame 101, and the air supply mechanism 400 is arranged at the top of the moving frame 101;

[0038] A rotating smoothing mechanism 300 for further smoothing the laid waterproofing membrane is provided at the bottom of the movable frame 101 away from the pressing roller group;

[0039] A material discharge mechanism 200 is provided on the top of the mobile frame 101. The material discharge mechanism 200 includes a support seat 201 and a positioning plate 204 connected to the top of the support seat 201. A fixed seat 216 is provided between two groups of the positioning plates 204. Two groups of top pressing rollers 217 are rotatably mounted on the fixed seat 216.

[0040] Two groups of positioning plates 204 are rotatably connected to two groups of placement rollers 218, and turning plates 210 are provided on both sides of the top of the placement rollers 218.

[0043] During the lifting and lowering adjustment of the trapezoidal seat 205, due to the cooperation between the inclined surface and the sliding roller 215, when the top pressing roller 217 approaches the coil, the side pressing roller 214 also approaches the coil to limit the position of the coil. The unwinding point of the coil can pass between the two sets of placing rollers 218.

[0047] When the trapezoidal seat 205 is lowered, the sliding roller 215 rolls on the inclined plane, and the two sets of inflection plates 210 rotate around the support shaft 213, thereby driving the two sets of side pressing rollers 214 to approach each other, and limiting the left and right positions of the coil placed on the placing roller 218. When the trapezoidal seat 205 is raised, the two sets of side pressing rollers 214 are pulled away by the elastic force of the spring telescopic rod 211.

[0048] like Figure 2 As shown, the support seat 201 is threadedly connected to the adjusting screw 202, and the ends of the two sets of adjusting screws 202 that are close to each other are rotatably connected to the limit plate 203, and the bottom of the limit plate 203 is slidably connected to the movable frame 101; the position of the limit plate 203 is adjusted by adjusting the screw 202, and the two sets of limit plates 203 cooperate to facilitate the guidance of the unwinding of the coil and reduce the skewness of the coil.

[0050] The coiled material released from the unwinding mechanism 200 can pass through the discharge hole 105, and the protective roller 106 can play a guiding role to reduce the friction during unwinding. After that, the coiled material is laid on the ground, and the laying roller 108 can assist the coiled material to be laid evenly on the roof.

[0051] like Figure 2 and Figure 3As shown, the rotating smoothing mechanism 300 includes a first smoothing disk 302 and a second smoothing disk 303, the top of the first smoothing disk 302 is fixedly connected to the first rotating shaft 308, the first mounting disk 309 is installed at the bottom of the moving frame 101, the first rotating shaft 308 is rotatably installed on the first mounting disk 309, the top of the moving frame 101 is installed with a motor 301 for driving the first rotating shaft 308 to rotate, the top of the second smoothing disk 303 is fixedly connected to the second rotating shaft 304, the bottom of the moving frame 101 is installed with a second mounting disk 310, and the second rotating shaft 304 is rotatably installed at the bottom of the second rotating shaft 304; two groups of second smoothing disks 303 are arranged at the bottom of the moving frame 101, a driven wheel 305 is installed on the second rotating shaft 304, and two groups of driving wheels 307 are installed on the first rotating shaft 308, each group of driving wheels 307 corresponds to each group of driven wheels 305, and the driving wheels 307 are connected to the driven wheels 305 through a synchronous belt 306;

[0052] The motor 301 drives the first rotating shaft 308 to rotate, and the first smoothing disk 302 rotates. The first rotating shaft 308 transmits the driven wheel 305 through the synchronous belt 306. The driven wheel 305 drives the second rotating shaft 304 to rotate, and the second smoothing disk 303 rotates. One group of first smoothing disks 302 and two groups of second smoothing disks 303 cooperate to make the waterproof membrane fit tightly against the roof. By rotating and smoothing, the laying of the waterproof membrane can be smoother to avoid wrinkles or folds, thereby enhancing the integrity and overall quality of the waterproof layer and avoiding gaps or bubbles.

[0053] like Figure 5 and Figure 6 As shown, one set of the positioning plates 204 is provided with an installation slot 209 for the waterproofing coiled material to pass through; the rolled waterproofing coiled material can pass through the installation slot 209 and be placed on top of the two sets of placement rollers 218.

[0056] The working principle of the present invention is as follows: the rolled waterproofing membrane can pass through the installation slot 209 and be placed on the top of the two groups of placement rollers 218. When the hydraulic telescopic rod 207 is working, the height of the lifting block 206 can be adjusted, thereby adjusting the height of the trapezoidal seat 205, and the two groups of top pressing rollers 217 can be adjusted to contact the membrane. When the trapezoidal seat 205 is lowered, the sliding roller 215 rolls on the inclined plane, and the two groups of turning plates 210 rotate around the support shaft 213, thereby driving the two groups of side pressing rollers 214 to approach, and the membrane placed on the placement roller 218 is limited to the left and right. When the trapezoidal seat 205 is raised, it is pulled by the elastic force of the spring telescopic rod 211, and the two groups of side pressing rollers 214 are separated.

[0057] The top pressing roller 217 and the side pressing roller 214 are adjusted to limit the position of the coiled material. Then the coiled material can pass through between the two groups of placing rollers 218 and be led to the pressing roller member. The coiled material can pass through the discharge hole 105. The protective roller 106 can play a guiding role to reduce the friction during unwinding. Then the coiled material is laid on the ground. The laying roller 108 can assist the coiled material to be laid flat on the roof. The motor 301 drives the first rotating shaft 308 to rotate, and the first smoothing disk 302 rotates. The first rotating shaft 308 drives the driven wheel 305 through the synchronous belt 306. The driven wheel 305 drives the second rotating shaft 304 to rotate, and the second smoothing disk 303 rotates.
