It is mainly formed by composite processing of layered structures such as a waterproof layer and a reinforcement layer. In the prior art, when the waterproof membrane is coated with glue and compounded, a glue roller needs to be set at the upper end of the glue groove, and the waterproof membrane moves over the top of the glue roller, so that the glue in the glue groove is applied to the bottom surface of the waterproof membrane by the rotating glue roller.

The glue coating roller 35 is connected to the tensioning roller 33 through a transmission component, so that when the tensioning roller 33 rotates, the glue coating roller 35 can be driven to rotate synchronously through the transmission component. When the glue coating roller 35 rotates, the glue in the glue groove 31 can be applied to the surface of the waterproof base material; the compounding mechanism 4 can extrude and compound the waterproof base materials wound on multiple unwinding rollers 2 into a composite waterproof coiled material, and the winding mechanism 5 is used to pull and wind the composite waterproof coiled material.

[0041] When preparing a composite waterproof membrane, first, two rolls of waterproof substrate to be composited are respectively installed on two unwinding rollers 2, and the waterproof substrate on one of the unwinding rollers 2 is passed through the gluing mechanism 3 to be coated with glue, and then adhered to the waterproof substrate on the other unwinding roller 2 and passed through the composite mechanism 4 together. The composite mechanism 4 extrude the two rolls of waterproof substrate to form a composite waterproof membrane, and then the formed composite waterproof membrane is reeled and pulled by the reeling mechanism 5 to continuously generate a composite waterproof membrane; wherein, the waterproof substrate is located below the gluing roller 35, and the tensioning roller 33 can tension and limit the waterproof substrate being transported. At the same time, the tensioning roller 33 can rotate synchronously under the drive of the friction resistance when the waterproof substrate is transported, and then the tensioning roller 33 drives the gluing roller 35 to rotate synchronously through the transmission assembly. When the gluing roller 35 rotates, the glue in the glue groove 31 can be continuously coated on the surface of the waterproof substrate transported below, thereby continuously performing the gluing and composite process of the waterproof substrate.

[0042] In this embodiment, the glue in the glue groove 31 is evenly coated on the upper surface of the waterproof substrate by the rotating glue coating roller 35, thereby preventing the glue from dripping from the waterproof substrate during the subsequent transportation of the waterproof substrate, reducing glue loss, and at the same time being beneficial to improving the composite effect of the waterproof substrate and improving the quality of the composite waterproof membrane after composite processing; through the coordinated drive of the tensioning roller 33 and the transmission component, the glue coating roller 35 can be automatically driven to rotate and apply glue during the transportation of the waterproof substrate, making the gluing process more convenient and quick, and when the pulling and moving speed of the waterproof substrate changes due to factors such as the membrane diameter during the preparation process, the glue coating roller 35 can be automatically driven to synchronize the speed, so that the rotating glue coating speed of the glue coating roller 35 and the moving conveying speed of the waterproof substrate are always kept in an adaptive state, thereby improving the uniformity of the glue coating and further improving the composite effect of the waterproof substrate.

[0043] Example 2

[0044] See also Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 As shown, the difference between this embodiment and the above embodiment is that the gluing mechanism 3 further includes a support plate 32, which is fixedly mounted on the top surface of the frame 1, and a glue groove 31 is fixedly mounted on the upper end of the support plate 32. The tensioning roller 33 and the gluing roller 35 are both rotatably mounted on the support plate 32. The support plate 32 is also equipped with at least one limiting roller 34 for supporting and limiting the waterproof substrate; the transmission assembly includes a synchronous belt 311 and two synchronous wheels 310, which are respectively fixedly mounted on the ends of the tensioning roller 33 and the gluing roller 35, and the two synchronous wheels 310 are connected by a synchronous belt 311.

[0045] Among them, the limiting roller 34 cooperates with the tensioning roller 33 to tension and limit the waterproof substrate, so that the glue-coated part of the waterproof substrate is stably set on the waterproof of the glue coating roller 35, and is in stable contact with the glue coating roller 35, thereby improving the uniformity of the glue coating. When the waterproof substrate is pulled and transported, the tensioning roller 33 can be driven to rotate synchronously through friction resistance. At this time, the tensioning roller 33 drives the glue coating roller 35 to rotate synchronously through the transmission of the synchronous wheel 310 and the synchronous belt 311. When the surface of the glue coating roller 35 rotates into the glue groove 31, the glue in the glue groove 31 adheres to the surface of the glue coating roller 35. Then the glue coating roller 35 continues to rotate to bring out the adhered glue and coat it on the upper surface of the waterproof substrate below. In this reciprocating manner, the glue can be continuously coated during the pulling and compounding process of the waterproof substrate.

[0046] Example 3

[0047] See also Figure 2-Figure 4 As shown, the difference between this embodiment and the above embodiment is that a slot 38 is formed at the lower end of the glue groove 31 and is located on one side of the glue outlet 36. A sealing plate 37 is slidably inserted into the interior of the slot 38. The inner end of the sealing plate 37 abuts against the surface of the glue roller 35. A cylinder 39 is fixedly mounted on the inner side wall of the support plate 32. The telescopic end of the cylinder 39 is fixedly connected to the outer end of the sealing plate 37.

[0048] Among them, the glue outlet 36 is sealed by the cooperation of the sealing plate 37 and the glue coating roller 35 to prevent the glue in the glue groove 31 from leaking out from the glue outlet 36. During composite glue coating, the sealing plate 37 is driven by the cylinder 39 to move along the slot 38 toward the outside of the glue outlet 36 to open the glue outlet 36. After that, when the glue coating roller 35 rotates, the glue in the glue groove 31 can be transported outward through the glue outlet 36 to be coated on the surface of the waterproof substrate. By adjusting the moving distance of the sealing plate 37, the opening and closing size of the glue outlet 36 can be controlled, so that the glue output and glue coating thickness can be adjusted as needed to meet different glue coating requirements.

[0049] Furthermore, the interior of the glue tank 31 is rotatably mounted with a plurality of equally spaced stirring shafts 313, each of which is fixedly mounted with a stirring blade 312. A rotation drive assembly capable of simultaneously driving the plurality of stirring shafts 313 to rotate and stir synchronously is fixedly mounted on the top of the glue tank 31. Furthermore, the interior of the glue tank 31 is fixedly mounted with a plurality of electric heating rods staggered with the stirring shafts 313.

[0050] Among them, the glue in the glue tank 31 can be stirred by driving the stirring shaft 313 and the stirring blade 312 through the rotating drive component and the glue can be heated by the electric heating rod, which can improve the uniformity and fluidity of the glue in the glue tank 31, prevent the glue from drying and hardening, and ensure that the glue can flow and apply normally.

[0051] Specifically, the rotary drive assembly includes a stirring motor 317, a chain 314, and a plurality of sprockets 315. The stirring motor 317 is connected to one of the stirring shafts 313 in a transmission manner. The plurality of sprockets 315 are respectively fixedly mounted on the top of the corresponding stirring shaft 313, and the plurality of sprockets 315 are connected to each other through the chain 314. A protective housing 316 is also fixedly mounted on the top of the glue tank 31 to protect the chain 314 and the sprockets 315. The stirring motor 317 is fixedly mounted on the top of the protective housing 316.

[0052] When the glue is stirred, the stirring motor 317 drives the stirring shaft 313 connected to it to rotate. At the same time, the stirring shaft 313 drives multiple stirring shafts 313 to rotate synchronously through the transmission of the sprocket 315 and the chain 314, so that the multiple stirring shafts 313 simultaneously drive the stirring blades 312 to stir the glue in the glue tank 31.

[0053] Example 4

[0054] See also Figure 1 、 Figure 4-Figure 6 、 Figure 8 As shown, the difference between this embodiment and the above embodiment is that the composite mechanism 4 includes a bracket 41, on which a lower composite pressure roller 43 is rotatably mounted, and a lifting seat 44 located above the lower composite pressure roller 43 is slidably mounted on the upper end of the bracket 41, and an upper composite pressure roller 42 is rotatably mounted on the lifting seat 44, and a hydraulic cylinder 45 is fixedly mounted on the top end of the bracket 41, and the telescopic end of the hydraulic cylinder 45 is fixedly connected to the top end of the lifting seat 44, and a composite drive unit is also mounted on the bracket 41, which can drive the upper composite pressure roller 42 and the lower composite pressure roller 43 to rotate in opposite directions at the same linear speed.

[0055] When preparing the composite waterproof membrane, firstly, the lifting seat 44 is driven to move upward by the hydraulic cylinder 45, thereby driving the upper composite pressing roller 42 to move upward, so as to adjust and increase the distance between the upper composite pressing roller 42 and the lower composite pressing roller 43, so as to facilitate the pulling and placing of the multi-layer waterproof substrate between the upper composite pressing roller 42 and the lower composite pressing roller 43, and then the lifting seat 44 and the upper composite pressing roller 42 are driven to move downward by the hydraulic cylinder 45 until the upper composite pressing roller 42 and the lower composite pressing roller 43 cooperate to extrude and composite the multiple waterproof substrates to form a composite waterproof membrane, and When the winding mechanism 5 pulls and rolls the composite waterproof membrane, the composite drive unit drives the upper composite pressure roller 42 and the lower composite pressure roller 43 to rotate in opposite directions at the same linear speed, thereby realizing dynamic extrusion and compounding of the waterproof substrate; and by adjusting the lifting and lowering of the upper composite pressure roller 42, not only can the multi-layer waterproof substrate be more conveniently pulled and placed between the upper composite pressure roller 42 and the lower composite pressure roller 43, but the distance between the upper composite pressure roller 42 and the lower composite pressure roller 43 can also be adjusted accordingly according to the thickness of the composite waterproof membrane to adapt to the production and processing of composite waterproof membranes of different thicknesses.

[0056] Specifically, the composite drive unit includes a composite motor 46, which is fixedly mounted on the bracket 41 and is transmission-connected to one end of the lower composite pressure roller 43. The other end of the lower composite pressure roller 43 extends to the outer side of the bracket 41 and is rotatably mounted with a lower connecting arm 48. The end of the lower composite pressure roller 43 is also fixedly mounted with a driving gear 410 located on the outer side of the lower connecting arm 48. A lifting slot 414 is provided on the bracket 41, and one end of the upper composite pressure roller 42 extends to the outside of the bracket 41 through the lifting slot 414, and the end of the upper composite pressure roller 42 is rotatably mounted. An upper connecting arm 47 is installed, and a driven gear 413 located on the outer side of the upper connecting arm 47 is fixedly installed at the end of the upper composite pressure roller 42. The upper connecting arm 47 and the end of the lower connecting arm 48 are rotatably connected via a connecting shaft 49, and an intermediate gear 411 is fixedly installed on the connecting shaft 49; a transmission gear 412 meshingly arranged between the driving gear 410 and the intermediate gear 411 is rotatably installed on the lower connecting arm 48, and a transmission gear 412 meshingly arranged between the intermediate gear 411 and the driven gear 413 is rotatably installed on the upper connecting arm 47;

[0057] During extrusion lamination, the laminating motor 46 drives the lower laminating roller 43 to rotate. At this time, the lower laminating roller 43 drives the driving gear 410 to rotate synchronously. Then, the driving gear 410 engages with the transmission gear 412 on the lower connecting arm 48 to drive the intermediate gear 411 to rotate. The intermediate gear 411 then drives the driven gear 413 to rotate through the transmission gear 412 on the upper connecting arm 47. The driven gear 413 then drives the upper laminating roller 42 to rotate, so that the upper laminating roller 42 and the lower laminating roller 43 cooperate to perform roll-pressing lamination on the waterproof substrate.

[0058] Among them, the total number of gears of the driving gear 410, the intermediate gear 411, the transmission gear 412 and the driven gear 413 is an even number (a total of six gears in this embodiment), the upper composite pressing roller 42 and the lower composite pressing roller 43 have the same diameter, and the total gear transmission ratio is 1, so that when the lower composite pressing roller 43 rotates, it can drive the upper composite pressing roller 42 to rotate in the same linear speed in the opposite direction, thereby making the upper composite pressing roller 42 and the lower composite pressing roller 43 exert the same force direction and speed on the composite waterproof membrane, which is beneficial to improving the rolling and compounding effect of the composite waterproof membrane and preventing the composite waterproof membrane from wrinkling due to the same force direction and speed on the upper and lower surfaces;

[0059] The gears are installed and driven by the upper connecting arm 47 and the lower connecting arm 48 that are connected by rotation, so that when the upper composite pressure roller 42 is moved up and down for adjustment, the upper composite pressure roller 42 and the lower composite pressure roller 43 can always maintain an engaged transmission state to ensure that the transmission process between the upper composite pressure roller 42 and the lower composite pressure roller 43 is carried out normally and stably.

[0060] Example 5

[0061] See also Figure 1 、 Figure 5 As shown, the difference between this embodiment and the above embodiment is that the winding mechanism 5 includes a winding roller 51 and a winding motor 52. The winding roller 51 is rotatably mounted on the end of the top surface of the frame 1, and the winding motor 52 is fixedly mounted on the frame 1 and is drivingly connected to the end of the winding roller 51.

[0062] When preparing the composite waterproof membrane, one end of the composite waterproof membrane is wound on the winding roller 51, and then the winding roller 51 is driven to rotate by the winding motor 52 so that the winding roller 51 continuously winds the prepared composite waterproof membrane.

[0063] Example 6

[0064] This embodiment discloses a method for preparing a composite waterproof membrane, and the specific steps are as follows:

[0065] The two rolls of waterproof substrate to be composited are respectively mounted on two unwinding rollers 2. The waterproof substrate on one of the unwinding rollers 2 is passed through the gluing mechanism 3 to be coated with glue, and then bonded to the waterproof substrate on the other unwinding roller 2. The two rolls of waterproof substrate are then squeezed by the composite mechanism 4 to form a composite waterproof membrane. The formed composite waterproof membrane is then reeled and pulled by the reeling mechanism 5 to continuously generate the composite waterproof membrane.

[0066] Among them, the tensioning roller 33 can tension and limit the waterproof substrate being transported, and at the same time, the tensioning roller 33 can rotate synchronously under the drive of the friction resistance when the waterproof substrate is transported. Then, the tensioning roller 33 drives the glue coating roller 35 to rotate synchronously through the transmission component. When the glue coating roller 35 rotates, the glue in the glue groove 31 can be continuously applied to the surface of the waterproof substrate being transported below, thereby continuously performing the gluing and compounding process of the waterproof substrate.
