DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-8 The modified asphalt waterproofing membrane provided by the embodiment of the present invention includes a modified asphalt waterproofing membrane, including a tire layer 1, the tire layer 1 is covered with a modified asphalt layer 2, one side of the modified asphalt layer 2 is covered with a removable isolation film, the other side of the modified asphalt layer 2 is covered and fixed with an aluminum film, and a plurality of grooves 3 are opened on the side of the modified asphalt layer 2 facing the aluminum film.

[0031] Specifically, the tire material layer 1 can be glass fiber cloth, asbestos cloth, cotton and linen fabric, the modified asphalt layer 2 can be molten petroleum asphalt with a modifier, the removable isolation film can be a plastic film, the aluminum film is aluminum foil, the groove 3 is a long groove, and when the aluminum foil layer is covered on the modified asphalt layer 2, the aluminum foil layer is also adapted and fitted with the groove wall surface of the groove 3, so that the structure of the groove 3 can be exposed and displayed on the modified asphalt layer 2; During actual use, when the modified asphalt waterproof membrane is wound, the groove walls on both sides of the groove 3 located on the inner side of the winding approach each other as the modified asphalt waterproof membrane is wound, which alleviates the extrusion and bulging of the inner curved surface when the modified asphalt waterproof membrane is wound, thereby preventing the aluminum foil layer from wrinkling due to extrusion and bulging during winding, so that the aluminum foil layer and the modified asphalt layer 2 maintain a good fitting effect, which is beneficial to maintaining the flatness of the aluminum foil layer, preventing the aluminum film from separating from the attached asphalt material surface, and preventing the aluminum film with creases and bulges from cracking, thereby ensuring a good waterproof effect of the modified asphalt waterproof membrane.

[0032] In another embodiment provided by the present invention, the length direction of each groove 3 is consistent with the width direction of the modified asphalt layer 2, so that when the modified asphalt waterproof membrane is wound, each groove 3 forms a bending line in its winding direction, which is beneficial to reduce the resistance of the modified asphalt waterproof membrane when it is wound, and also facilitates the winding of the modified asphalt waterproof membrane.

[0033] In another embodiment provided by the present invention, the cross-section of each groove 3 is a V-shaped structure, so that when the modified asphalt waterproofing membrane is wound, the groove body of the groove 3 can better deform with the winding of the modified asphalt waterproofing membrane, thereby being more compatible with the winding of the modified asphalt waterproofing membrane.

[0034] In another embodiment provided by the present invention, the bottom of the groove 3 is an arc-shaped bottom, so that when the groove 3 is deformed, an arc-shaped space structure can be formed at the bottom of the groove 3, which is beneficial to avoid that the bending rate of the aluminum film located at the bottom of the groove 3 is too large, and is beneficial to prevent the aluminum film from forming creases at the bottom of the groove 3 and causing the aluminum film to rupture.

[0035] In another embodiment provided by the present invention, a plurality of exhaust rib grooves 4 are provided on the groove wall of the gully groove 3, and the plurality of exhaust rib grooves 4 are evenly distributed along the length direction of the gully groove 3, and the interval value of the plurality of exhaust rib grooves 4 is smaller than the groove width value of the exhaust rib groove 4, and the groove length direction of the exhaust rib groove 4 is perpendicular to the groove bottom of the gully groove 3, wherein each exhaust rib groove 4 forms a first meshing surface 4.1 on one side of the gully groove 3, and each exhaust rib groove 4 forms a second meshing surface 4.2 on the other side of the gully groove 3, and each exhaust rib groove 4 located on one side of the gully groove 3 forms the first meshing surface 4.1, and each exhaust rib groove 4 located on the other side of the gully groove 3 forms the second meshing surface 4.2. The first meshing surface 4.1 and the second meshing surface 4.2 can mesh and snap together when they overlap. In actual use, when the groove body of the groove 3 can be better deformed as the modified asphalt waterproofing membrane is wound, and the groove walls of the groove 3 are close to each other, the first meshing surface 4.1 and the second meshing surface 4.2 can mesh, so that when the roll column structure is formed when the modified asphalt waterproofing membrane is wound, the roll column structure can be prevented from slipping and loosening in the axial direction, which is beneficial to maintaining the stability of the overall shape of the roll column structure, and at the same time makes the aluminum film on the groove 3 fit more tightly in the groove 3.

[0036] In another embodiment provided by the present invention, the spacing of the parallel arrangement of the plurality of grooves 3 in the direction from the starting end of the modified asphalt layer 2 to the tail end of the modified asphalt layer 2 is distributed from dense to sparse. In actual use, as the diameter of the roll column structure formed when the modified asphalt waterproof membrane is wound increases, the corresponding curvature of the modified asphalt waterproof membrane gradually decreases. The grooves 3 distributed from dense to sparse are adapted to the change in the curvature of the modified asphalt waterproof membrane, which is beneficial for the modified asphalt waterproof membrane to be in a tight and fitting state after winding.

[0037] The modified asphalt waterproofing membrane prepared in the above-mentioned manner relates to a preparation device for the modified asphalt waterproofing membrane, which comprises a base 6, on which a film laminating mechanism 7 is provided, the film laminating mechanism 7 comprises a film supply component 8, a film pasting component 9 and a driving motor unit 15, the driving motor unit 15 provides power for the film supply component 8 and the film pasting component 9 to operate through a transmission component 5, the film pasting component 9 comprises a pressing roller 9.1 capable of pasting the aluminum film released by the film supply component 8 on the modified asphalt layer 2, and a protrusion 9.2 capable of embossing grooves 3 on the modified asphalt layer 2 is fixed on the pressing roller 9.1;

[0038] The base 6 is located on the conveying production line of the modified asphalt waterproofing membrane, and the coating mechanism 7 is located above the conveying production line of the modified asphalt waterproofing membrane, and can cover one side of the modified asphalt layer of the modified asphalt waterproofing membrane with aluminum film. In actual use, the film supply component 8 in the coating mechanism 7 provides aluminum film for the film pasting component 9, and the driving motor unit 15 provides driving power for the film supply component 8 and the film pasting component 9 through the transmission component 5, so that the film pasting work of the film pasting component 9 can proceed smoothly. Furthermore, the pressure roller 9.1 of the film pasting component 9 can press the aluminum film released by the film supply component 8 on the modified asphalt layer of the modified asphalt waterproofing membrane to make the adhesion more complete. At the same time, during the pressing process, the pressure roller 9.1 also rotates axially. The rotation direction of the pressure roller 9.1 close to the modified asphalt waterproofing membrane is consistent with the moving direction of the production line of the modified asphalt layer. In this process, the protrusion 9.2 on the pressure roller 9.1 can apply pressure on the side of the modified asphalt layer covered with the aluminum film, so that the protrusion 9.2 forms a groove 3 on the modified asphalt layer.

[0039] In another embodiment provided by the present invention, the film supply assembly 8 includes a rotating shaft unit 8.1 that can rotate the aluminum film roll to release the aluminum film, and a storage box 8.2 is provided at the bottom of the rotating shaft unit 8.1. The storage box 8.2 is a top-opening box for receiving the roll core of the aluminum film roll that falls off when it is used up. Specifically, the rotating shaft unit 8.1 includes an installation frame 11 located directly above the production line of the modified asphalt layer, the frame mouth surface of the installation frame 11 is parallel to the moving surface of the production line of the modified asphalt layer, and the length direction line of the installation frame 11 is toward the moving direction of the production line of the modified asphalt layer. The bottom of the installation frame 11 is fixed to the base 6 by a plurality of supporting legs 12, and two supporting rollers 13 that are arranged in parallel and rotate in the same direction are rotatably installed on the installation frame 11, and the axis center line of the supporting roller 13 is perpendicular to the moving direction line of the production line of the modified asphalt layer, and the storage box 8.2 is fixed to the installation frame 11 by a hanging rod.

[0040] During actual use, the aluminum film roll is placed on two parallel supporting rollers 13 that rotate in the same direction. When the supporting rollers 13 rotate forward, the aluminum film roll rotates forward, causing the aluminum film on the aluminum film roll to loosen, thereby facilitating the provision of aluminum film to the film sticking component 9. Specifically, the loose aluminum film falls downward from the mounting frame 11, and then covers the modified asphalt layer on the production line when passing through the film sticking component 9. The modified asphalt layer that has not yet dried and is in a damp state adheres to the aluminum film, and then the aluminum film continues to move with the production line.

[0041] In another embodiment provided by the present invention, the whole of the raised portion 9.2 is in the shape of an elongated strip, and the length direction line of the raised portion 9.2 is parallel to the axis line of the pressure roller 9.1, so that the groove 3 can be formed on the modified asphalt layer in the shape of an elongated strip, wherein both ends of the pressure roller 9.1 are rotatably connected to a connecting plate 14 fixed to the mounting frame 11, the axis line of the pressure roller 9.1 is parallel to the axis line of the supporting roller 13, and the roller body of the pressure roller 9.1 is in a smooth cylindrical structure, so that the aluminum film can slide smoothly on the bottom of the pressure roller 9.1, and the number of the raised portions 9.2 is several, preferably, the raised portions 9.2 are There is one raised portion 9.2 on the roller body of the pressure roller 9.1, and the raised portion 9.2 includes a bar 9.21 parallel to the axis of the pressure roller 9.1, and a plurality of evenly distributed protrusions 9.22 are fixed on both sides of the bar 9.21. In actual use, when the raised portion 9.2 is squeezed with the modified asphalt layer, the bar 9.21 forms a groove 3 on the modified asphalt layer, and the protrusion 9.22 forms a venting ridge 4. It should be further explained that the side where the bar 9.21 and the protrusion 9.22 are squeezed with the modified asphalt layer are both rounded sides to avoid damage to the aluminum film.

[0042] In another embodiment provided by the present invention, the driving motor unit 15 is a double-headed motor composed of a first motor 15.1 and a second motor 15.2. Both output shafts of the driving motor unit 15 are long shafts. The transmission assembly 5 includes a first transmission unit 16 and a second transmission unit 17. The output shaft at one end of the driving motor unit 15 is transmission-connected to the film supply assembly 8 through the first transmission unit 16, that is, the output shaft of the first motor 15.1 is transmission-connected to the film supply assembly 8 through the first transmission unit 16, the output shaft at the other end of the driving motor unit 15 is transmission-connected to the film pasting assembly 9 through the second transmission unit 17, the output shaft of the second motor 15.2 is transmission-connected to the film pasting assembly 9 through the second transmission unit 17, and the driving motor unit 15 is connected to the mounting frame 11 through the reciprocating unit 18;

[0043] The reciprocating moving unit 18 includes an installation box 18.1 fixed on the installation frame 11, a servo straight rod motor 18.2 is arranged inside the installation box 18.1, the output direction of the servo straight rod motor 18.2 is parallel to the length direction of the output shaft of the driving motor unit 15, the driving motor unit 15 is located inside the installation box 18.1, the installation box 18.1 is a cylindrical box, the length direction of the installation box 18.1 is parallel to the length direction of the installation frame 11, the output shafts at both ends of the driving motor unit 15 are movably extended outside the installation box 18.1, the servo straight rod motor 18.2 can control the second motor 15.2 of the driving motor unit 15 to move along the length direction of the installation frame 11 in the installation box 18.1, and the length direction of the output shaft of the driving motor unit 15 is parallel to the length direction of the installation frame 11;

[0044] Among them, the output shaft of the first motor 15.1 has the same rotation speed as the output shaft of the second motor 15.2, and the output shaft of the first motor 15.1 and the output shaft of the second motor 15.2 are on the same straight line. The bottom of the second motor 15.2 is equipped with an auxiliary moving wheel that can move in the length direction of the installation box 18.1. A toothed plate 15.11 is fixed to the bottom of the first motor 15.1, and a toothed roller 15.12 is meshed at the bottom of the toothed plate 15.11. Both ends of the toothed roller 15.12 are rotatably connected to the installation box 18.1. When the toothed roller 15.12 rotates in the first direction, the output shaft of the first motor 15.1 extends toward the outside of the installation box 18.1. The toothed roller 15.12 is provided with a connecting strip 15.13 fixed to the second motor 15.2. The length direction of the connecting strip 15.13 is parallel to the output shaft of the second motor 15.2, and the length direction of the connecting strip 15.13 is perpendicular to the axis of the toothed roller 15.12. The connecting strip 15.13 is provided with a groove 15.15, in which a single push piece 15.14 is movably hinged, and the push piece 15.14 is connected to the groove 15.15 by a spring 15.16. Under the action of the spring 15.16, the push piece 15.14 extends out of the groove 15.15. When the second motor 15.2 moves toward the first motor 15.1 under the drive of the servo linear motor 18.2, the push piece 15.14 contacts the groove end wall of the groove 15.15, and the push piece 15.14 can push the teeth of the gear roller 15.12 to make the gear roller 15.12 deflect in the first direction. When the second motor 15.2 moves away from the first motor 15.1 under the drive of the servo linear motor 18.2, the push piece 15.14 and the teeth of the gear roller 15.12 exert force, and the spring 15.16 is squeezed and deformed, and the push piece 15.14 is separated from the groove end wall of the groove 15.15, and the push piece 15.14 retreats into the groove 15.15, thereby not exerting any deflection drive on the gear roller 15.12.

[0045] Thus, each time the second motor 15.2 moves toward the first motor 15.1, the output shaft of the first motor 15.1 will extend toward the outside of the installation box 18.1 by a certain displacement;

[0046] The first motor 15.1 of the driving motor unit 15 has an initial position and a left-biased position in the installation box 18.1, and the second motor 15.2 of the driving motor unit 15 has a central position and a right-biased position in the installation box 18.1. The output shaft of the servo straight rod motor 18.2 is fixed to the second motor 15.2. When the servo straight rod motor 18.2 performs a contraction movement, the second motor 15.2 moves from the central position to the right-biased position. When the servo straight rod motor 18.2 performs an extension movement, the second motor 15.2 moves from the right-biased position to the central position.

[0047] The first transmission unit 16 includes a first rotating disk 16.1 rotatably mounted with the mounting frame 11, a first pulley 16.2 is concentrically fixed to the back of the first rotating disk 16.1, a transmission belt 16.3 is transmission-connected to the first pulley 16.2, and the transmission belt 16.3 is transmission-connected to a second pulley fixed to the end of the supporting roller 13, so that the first rotating disk 16.1 can rotate synchronously with the supporting roller 13, and the front side of the first rotating disk 16.1 is a rough surface. Specifically, the first rotating disk 16.1 is fixed with a plurality of dispersed protrusions 16.4, the front surface of the first rotating disk 16.1 contacts with a first fixed wheel 16.5 fixed with the output shaft of the first motor 15.1 of the driving motor unit 15, and a plurality of evenly distributed attachment wheels 16.6 are rotatably mounted on the wheel edge of the first fixed wheel 16.5, wherein the wheel body surface of the first fixed wheel 16.5 is perpendicular to the disk surface of the first rotating disk 16.1, and the wheel body surface of each attachment wheel 16.6 is perpendicular to the wheel body surface of the first fixed wheel 16.5;

[0048] The second transmission unit 17 includes a second rotating disk 17.1 rotatably mounted with the mounting frame 11, a first sprocket 17.2 is concentrically fixed to the back of the second rotating disk 17.1, a first transmission chain 17.3 is transmission-connected to the first sprocket 17.2, the first transmission chain 17.3 is transmission-connected to a second sprocket 17.4 rotatably connected with the mounting frame 11, a third sprocket 17.7 is concentrically fixed to the second sprocket 17.4, the third sprocket 17.7 is rotationally connected to the pressure roller 9.1 through a second transmission chain 17.5, a second fixed wheel 17.6 fixed to the output shaft of the second motor 15.2 of the driving motor unit 15 is in contact with the front of the second rotating disk 17.1, the second fixed wheel 17.6 and the first fixed wheel 16.5 are of the same structure and specification, and the second rotating disk 17.1 and the first rotating disk 16.1 are of the same structure and specification;

[0049] When the first motor 15.1 of the driving motor unit 15 reaches the left-biased position in the installation box 18.1, the first motor 15.1 reaches the maximum outward extension position, at which time the first fixed wheel 16.5 is close to the center position of the first rotating disk 16.1, and the first rotating disk 16.1 is in the highest speed rotation state; when the first motor 15.1 of the driving motor unit 15 reaches the initial position in the installation box 18.1, the first fixed wheel 16.5 is close to the edge position of the first rotating disk 16.1, and the first rotating disk 16.1 is in the lowest speed rotation state;

[0050] When the second motor 15.2 of the driving motor unit 15 reaches the center position in the installation box 18.1, when the second fixed wheel 17.6 reaches the edge position of the second rotating disk 17.1, the second rotating disk 17.1 is in the lowest speed rotation state; when the second motor 15.2 of the driving motor unit 15 reaches the right-biased position in the installation box 18.1, at this time, the second fixed wheel 17.6 reaches the center position of the second rotating disk 17.1, and the second rotating disk 17.1 is in the highest speed rotation state;

[0051] In actual use, at the beginning, the first motor 15.1 of the driving motor unit 15 is located at the initial position, and the first rotating disk 16.1 rotates at a low speed, so that the aluminum foil roll rotates slowly. In addition, when the second motor 15.2 moves from the right-biased position to the central position, the second rotating disk 17.1 decelerates, so that the rotation speed of the pressure roller 9.1 slows down, so that the spacing of the grooves 3 formed by the protrusions 9.2 on the modified asphalt layer gradually expands, and the grooves 3 with non-equidistant distribution can be formed on the modified asphalt layer. At the same time, each time the second motor 15.2 moves from the right-biased position to the central position, that is, each time the second motor 15.2 moves toward the direction close to the first motor 15.1, the first motor 15.1 moves a short distance toward the left-biased position, so that the speed of the first rotating disk 16.1 gradually increases, and the diameter value of the aluminum foil roll is gradually decreasing, so that the speed increase of the rotating shaft unit 8.1 accelerates the rotation and release speed of the aluminum foil roll, so that the amount of aluminum foil released from the aluminum foil roll can always meet the needs of the film sticking component 9.
