Description

Technical Field

[0001] This invention relates to the field of waterproof construction technology, specifically to a device for hot-melt laying of waterproof membrane rolls. Background Technology

[0002] Hot-melt laying of waterproof membrane is a widely used construction method in building waterproofing projects. Its basic principle is to use a flame heater (flame gun) to heat the bottom surface of the modified bitumen waterproof membrane, so that the bitumen on the bottom surface of the membrane melts, and then the membrane is pasted on the base layer to form a continuous and reliable waterproof layer.

[0003] However, existing waterproof membrane hot-melt laying devices have the following shortcomings: On the one hand, after laying the membrane, traditional construction devices rely solely on transverse pressure rollers to press the membrane transversely once. For example, a waterproof membrane laying edge-pressing hot-melt device proposed in patent application number CN202221687795.4 uses pressure rollers to squeeze the laid membrane, which makes it difficult to ensure sufficient and uniform bonding between the membrane and the substrate, resulting in quality defects such as local bubbles and delamination.

[0004] Therefore, there is an urgent need for a device that can reciprocate and compact the already laid waterproof membrane for hot-melt laying. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waterproof membrane hot-melt laying device, which solves the problem that using pressure rollers to squeeze the laid membrane makes it difficult to ensure sufficient and uniform bonding between the membrane and the substrate, leading to quality defects such as localized bubbles and delamination.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof membrane hot-melt laying device, comprising a base frame with casters below the base frame, and further comprising: a waterproof membrane located above the base frame, a guide roller located below one side of the waterproof membrane, and a transverse pressure roller located below the waterproof membrane; an air tank located in front of the base frame, with a baffle between the air tank and the membrane located between the guide roller and the transverse pressure roller, and a flame gun mounted on the air tank for heating the membrane located between the guide roller and the transverse pressure roller; a vertical rolling roller located downstream of the transverse pressure roller, the vertical rolling roller being arranged perpendicular to the transverse pressure roller in the horizontal direction; and a reciprocating mechanism located above the base frame for driving the vertical rolling roller to reciprocate, so that the vertical rolling roller repeatedly rolls the laid membrane during the movement of the base frame.

[0007] Furthermore, the vertical rolling roller is mounted on the bearing seat, and the reciprocating mechanism includes a first reciprocating mechanism, which includes: two reciprocating lead screws arranged side by side, the two reciprocating lead screws being rotatably mounted on a first support frame located on the base frame, a reciprocating slider being provided on the reciprocating lead screw, a column being inserted into one side of the reciprocating slider, a connecting plate being installed between the upper ends of the two columns, the lower ends of the columns being fixedly connected to the bearing seat, and a first spring being provided between the reciprocating slider and the bearing seat; a belt structure being used to drive and connect the two reciprocating lead screws; and a drive structure being installed on the first support frame to drive one of the reciprocating lead screws to rotate.

[0008] Furthermore, the vertical rolling rollers are provided in two sets, which are arranged side by side. The reciprocating mechanism includes a second reciprocating mechanism located above and between the two sets of vertical rolling rollers. The second reciprocating mechanism is used to control the two sets of vertical rolling rollers to move closer to or further away from each other. The mechanism also includes an adjusting mechanism located at both ends of the vertical rolling rollers. The adjusting mechanism is used to control the two sets of vertical rolling rollers to press against the roll material when they move away from each other, and to lift them upwards and detach them from the roll material when they move closer to each other.

[0009] Furthermore, the adjustment mechanism includes: a moving rail, a vertical track groove inside the moving rail, a slider that can slide vertically inside the moving rail, a spring three between the lower end of the slider and the bottom surface of the moving rail, a central shaft at both ends of the vertical rolling roller, the middle part of the central shaft being rotatably mounted on the slider, and the second reciprocating mechanism being used to control the horizontal movement of the moving rail; a slide rail housing, the slide rail housing being fixed to the base frame by a hanger and located at both ends of the vertical rolling roller, a partition in the middle of the slide rail housing, the partition dividing the slide rail housing into a lower horizontal rail, an outer upward inclined rail, an upper horizontal rail and an inner downward inclined rail, one end of the central shaft being able to slide inside the slide rail housing, and the spring three being in a compressed state when the central shaft is located in the lower horizontal rail.

[0010] Furthermore, a pressure plate is installed below the partition via spring four, which applies pressure to the central shaft when the central shaft is within the lower horizontal rail, so that the vertical rolling roller presses it tightly onto the roll material.

[0011] Furthermore, a V-shaped spring sheet is provided inside the inner inclined rail. The two free ends of the V-shaped spring sheet are fixed to the partition plate and the pressure plate respectively, which is used to restrict the vertical rolling roller from entering the upper horizontal rail when it moves outward.

[0012] Furthermore, the second reciprocating mechanism includes: a connecting rod, which consists of four rods. The lower end of each connecting rod is hinged to the upper end of a corresponding moving rail, and the upper end of the connecting rod is hinged to the second connecting plate. A third bracket is also installed above the base frame, and the third bracket is equipped with a structure that can drive the second connecting plate to reciprocate and move up and down.

[0013] Furthermore, the reciprocating lifting structure includes: a pressure rod, the lower end of which passes through the third bracket and is fixedly connected to the connecting plate; a cam, the cam being located above the pressure rod, and a spring being sleeved on the outer circumference of the pressure rod, the spring being located between the cam and the third bracket; and a drive structure, the drive structure being mounted on the third bracket and used to drive the cam to rotate.

[0014] Furthermore, the outer surface of the vertical rolling roller is fitted with balls.

[0015] Furthermore, a dispersion box is provided on the area of ​​the barrier plate opposite to the roll material between the guide roller and the transverse pressure roller, and a threaded connection hole is provided on the side of the dispersion box near the gas tank; The barrier plate has parallel nozzles installed on the side near the roll material, and the flame gun can be threadedly connected to the nozzles. The base frame has a handle on the side near the gas tank.

[0016] The present invention has the following beneficial effects: (1) The waterproof membrane hot-melt laying device sets a vertical roller downstream of the horizontal roller and uses a reciprocating mechanism to drive the vertical roller to repeatedly roll the laid membrane during the device's movement, which effectively improves the bonding quality between the membrane and the base layer, eliminates air bubbles and delamination. The vertical roller is arranged perpendicular to the horizontal roller in the horizontal direction, realizing rolling in both longitudinal and transverse directions, ensuring the full and uniform compaction of the membrane laying, and significantly improving the integrity and reliability of the waterproof layer.

[0017] (2) The waterproof membrane hot-melt laying device controls the movement direction of the two sets of vertical rollers through the second reciprocating mechanism, so that the two sets of vertical rollers always roll from the middle of the membrane to both sides, rather than rolling from both sides to the middle. This avoids the problem of residual air bubbles between the membrane and the base layer being squeezed to the middle, causing the air bubbles to be unable to be discharged. When the two sets of vertical rollers advance from the middle to both sides, the air bubbles are gradually driven to the edge of the membrane and discharged naturally along the rolling direction, eliminating quality defects such as bulging and delamination caused by residual air bubbles after the membrane is laid. This significantly improves the bonding uniformity between the waterproof membrane and the base layer and the overall reliability of the waterproof layer, and also prevents the laid membrane from shifting position.

[0018] (3) The waterproof membrane hot-melt laying device enables two sets of vertical rollers to work together through the setting of the adjustment mechanism. When they are far apart, they press the membrane to compact it and when they are close together, they automatically lift and detach from the membrane, realizing the automatic switching of reciprocating compaction action and improving the degree of construction automation.

[0019] (4) The waterproof membrane hot-melt laying device has balls installed on the outer surface of the vertical roller, which further reduces the frictional resistance during rolling, protects the membrane surface from damage, and improves the rolling effect.

[0020] (5) The waterproof membrane hot-melt laying device concentrates the heat of the flame gun to the area of ​​the membrane that needs to be heated by the barrier baffle, effectively reducing heat loss and improving heating efficiency, while preventing heat from spreading to non-heated areas and improving construction safety.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0026] The following is based on Figures 1-13 This invention describes a waterproof membrane hot-melt laying device provided in an embodiment of the invention.

[0027] Example 1, please refer to Figures 1-6 This invention provides a waterproof membrane hot-melt laying device, including a base frame 1. The base frame 1 is provided with casters 2 at the bottom, which allows the entire device to move flexibly on the construction surface, making it easy for operators to push and turn. An air tank 3 is provided at the front of the base frame 1, and a flame gun 31 is connected to the air tank 3. A handle 103 is also provided on the side of the base frame 1 near the air tank 3, which makes it easy for operators to hold and push the device forward.

[0028] Combination Figure 1 and Figure 3As shown, a second support frame 102 is installed above the base frame 1, and the waterproof membrane 12 is located on the second support frame 102 and is supported by a roll. A guide roller 13 is provided on one side of the waterproof membrane 12 to guide the membrane to unfold downwards at an appropriate angle and prevent the membrane from deviating. A transverse pressure roller 9 is provided below the waterproof membrane 12. The transverse pressure roller 9 performs preliminary transverse pressing on the newly laid membrane to make the membrane adhere to the base layer.

[0029] The flame gun 31 sprays flames toward the roll material area between the guide roller 13 and the transverse pressure roller 9 to heat and melt the modified asphalt on the bottom surface of the roll material, making it adhesive for bonding with the substrate. A baffle 14 is provided between the gas canister 3 and the roll material located between the guide roller 13 and the transverse pressure roller 9. The baffle 14 guides and concentrates the heat generated by the flame gun 31 onto the area of ​​the roll material to be heated, preventing the flame or hot gas from directly spreading to other areas, thus improving heating efficiency and enhancing safety.

[0030] Downstream of the transverse pressure roller 9, a vertical pressure roller 4 is provided. The arrangement direction of the vertical pressure roller 4 is perpendicular to the horizontal direction of the transverse pressure roller 9, that is, the transverse pressure roller 9 extends along the width direction of the device, and the vertical pressure roller 4 is arranged along the traveling direction of the device, thereby achieving longitudinal compaction of the roll material. A reciprocating mechanism is also provided above the base frame 1 to drive the vertical pressure roller 4 to reciprocate, so that the vertical pressure roller 4 can repeatedly compact the laid roll material back and forth during the movement of the device, fully compacting the bonding interface between the roll material and the base layer.

[0031] like Figure 3 and Figure 5 As shown, preferably, a dispersion box 141 is provided on the area of ​​the roll material opposite to the guide roller 13 and the transverse pressure roller 9 on the barrier baffle 14. A threaded connection hole 143 is provided on the side of the dispersion box 141 near the gas tank 3, allowing the flame gun 31 to be threadedly connected to the dispersion box 141 via the threaded connection hole 143 for easy disassembly and replacement. Parallel nozzles 142 are installed on the side of the barrier baffle 14 near the roll material. The flame emitted by the flame gun 31 is evenly dispersed through the dispersion box 141 and then ejected through each nozzle 142, achieving uniform heating of the roll material heating area and avoiding localized overheating or underheating.

[0032] The vertical rolling roller 4 is mounted on the bearing seat 41, and the reciprocating mechanism adopts a first reciprocating mechanism 5. The first reciprocating mechanism 5 includes two reciprocating lead screws 51 arranged side by side, which are rotatably mounted on the first support frame 101 located on the base frame 1. A reciprocating slider 52 is provided on the reciprocating lead screw 51, and the reciprocating slider 52 moves back and forth along the lead screw axis as the reciprocating lead screw 51 rotates. A column 53 is inserted into one side of the reciprocating slider 52, and a connecting plate 54 is installed between the upper ends of the two columns 53. The lower ends of the columns 53 are fixed to the bearing seat 41, thereby transmitting the linear motion of the reciprocating slider 52 to the bearing seat 41 and the vertical rolling roller 4. A first spring 6 is provided between the reciprocating slider 52 and the bearing seat 41. The first spring 6 plays a buffering and pressing role, ensuring that the vertical rolling roller 4 maintains appropriate pressure on the roll material during the rolling process and absorbs the impact force caused by the unevenness of the base layer.

[0033] Two reciprocating lead screws 51 are connected by a belt structure 56, enabling the two lead screws to rotate synchronously. The drive structure 55 is installed on the first support frame 101, driving one of the reciprocating lead screws 51 to rotate, which in turn drives the other reciprocating lead screw 51 to rotate synchronously via the belt structure 56, thereby driving the vertical rolling roller 4 to perform reciprocating lateral movement, realizing repeated rolling of the laid roll material.

[0034] The aforementioned drive structure 55 consists of a motor, a belt, and pulleys, which will not be described in detail here.

[0035] Example 2, combined with Figures 7-13 As shown, there are two sets of vertical rollers 4, which are arranged side by side. The reciprocating mechanism adopts a second reciprocating mechanism 7. The second reciprocating mechanism 7 is located above and between the two sets of vertical rollers 4, and is used to control the two sets of vertical rollers 4 to move closer to or further away from each other.

[0036] It also includes an adjustment mechanism 8, which is located at both ends of the vertical rolling rollers 4. The adjustment mechanism 8 is used to control the two sets of vertical rolling rollers 4 to press on the roll material when they are far apart from each other, and to lift up and detach from the roll material when they are close to each other. This ensures that the two vertical rolling rollers 4 in this embodiment can only roll the roll material from the middle to both sides, and cannot roll the roll material from both sides to the middle, so as to avoid the roll material from arching in the middle.

[0037] Specifically, the adjustment mechanism 8 includes a moving rail 85 and a slide housing 81. The moving rail 85 has a vertical track groove, within which a vertically sliding slider 86 is installed. A spring 87 is positioned between the lower end of the slider 86 and the bottom surface of the moving rail 85. The vertical rolling roller 4 has a central shaft 42 at both ends, with the middle of the central shaft 42 rotatably mounted on the slider 86, i.e., the slider 86 serves as the bearing of the central shaft 42. When the slider 86 compresses the spring 87, the vertical rolling roller 4 presses against the laid roll material. When the spring 87 is in its natural state, it pushes the slider 86 upwards, at which point the vertical rolling roller 4 detaches from the laid roll material.

[0038] The aforementioned second reciprocating mechanism 7 is used to control the horizontal movement of the moving rail 85, thereby causing the two vertical rolling rollers 4 to move horizontally.

[0039] The slide rail housing 81 is fixed to the base frame 1 by the hanger 10 and is located at both ends of the vertical rolling roller 4. A partition 82 is provided in the middle of the slide rail housing 81, dividing the interior of the slide rail housing 81 into a lower horizontal rail 811, an outer upward-sloping rail 812, an upper horizontal rail 813, and an inner downward-sloping rail 814. One end of the central shaft 42 can slide along the aforementioned rails within the slide rail housing 81.

[0040] When the central shaft 42 is located within the lower horizontal rail 811, the spring 3 87 is compressed, and the vertical roller 4 is pressed against the roll material by the elastic force of the spring 3 87, applying uniform rolling pressure to the roll material. When the central shaft 42 reaches the position of the outer upper inclined rail 812, the spring 3 87 loses pressure, pushing the slider 86 upward, and the central shaft 42 enters the upper horizontal rail 813, thereby lifting the vertical roller 4 away from the roll material, completing the lifting action of the pressure roller, and avoiding the situation where the middle of the roll material arches due to rolling during the return stroke.

[0041] When the two sets of vertical rolling rollers 4 move away from each other again, the central shaft 42 slides out along the inner downward inclined rail 814 and falls back into the lower horizontal rail 811. The spring 3 87 is compressed again, and the vertical rolling rollers 4 press the roll material again, starting a new round of rolling.

[0042] Preferably, a pressure plate 83 is installed below the partition 82 via a spring 4 88. When the central shaft 42 is within the lower horizontal rail 811, the pressure plate 83 applies downward pressure to the central shaft 42 under the elastic force of the spring 4 88, increasing the rolling pressure of the vertical roller 4 on the roll material and further improving the compaction effect.

[0043] Preferably, a V-shaped spring piece 84 is provided inside the inner inclined rail 814, and the two free ends of the V-shaped spring piece 84 are fixed to the partition plate 82 and the pressure plate 83 respectively. The V-shaped spring piece 84 is used to restrict the vertical roller 4 from entering the upper horizontal rail 813 when it moves outward, and to prevent the central shaft 42 from accidentally entering the upper horizontal rail 813 when it does not need to be lifted, so as to ensure the accuracy and reliability of the roller action.

[0044] The second reciprocating mechanism 7 includes four connecting rods 76. The lower end of each connecting rod 76 is hinged to the upper end of the opposite moving rail 85, and the upper end of the connecting rod 76 is hinged to the connecting plate 75. A third support 104 is installed above the base frame 1. The third support 104 has a structure that can drive the connecting plate 75 to reciprocate. This structure includes a pressure rod 74, the lower end of which passes through the third support 104 and is fixed to the connecting plate 75. A cam 72 is located above the pressure rod 74, and a spring 73 is sleeved on the outer circumference of the pressure rod 74. The spring 73 is located between the cam 72 and the third support 104. A second drive structure 71 is installed on the third support 104 and is used to drive the cam 72 to rotate. When the cam 72 rotates, its contour alternately pushes the pressure rod 74 down and the spring 73 elastically returns to its original position, thereby realizing the reciprocating lifting and lowering of the connecting plate 75. This, in turn, drives the moving rail 85 and the vertical rolling roller 4 to move closer or further apart through the connecting rods 76.

[0045] Compared to Embodiment 1, Embodiment 2, driven by the second reciprocating mechanism 7, has the following advantages: First, when the two sets of vertical rollers 4 expand to both sides, the lateral force applied to the roll material is opposite in direction and equal in magnitude, and the forces on the left and right sides cancel each other out. The roll material will not shift laterally during the rolling process, effectively ensuring the positional accuracy of the laid roll material. Second, the two sets of vertical rollers 4 advance from the center line of the roll material to both sides each time, driving the residual air bubbles between the roll material and the base layer from the center to the edge. The air bubbles can naturally escape along the edge of the roll material, avoiding the problem of air bubbles being repeatedly pushed and unable to be effectively discharged in unidirectional reciprocating rolling. This makes the bonding interface between the roll material and the base layer more uniform and dense, improving the laying quality and long-term durability of the waterproof layer.

[0046] Specifically, the aforementioned drive structure 271 consists of a motor, a belt, and a pulley, which will not be elaborated here.

[0047] Preferably, the outer surface of the vertical roller 4 is equipped with balls. The ball structure allows the vertical roller 4 to distribute pressure in all directions in a point-contact manner when rolling the roll material. This not only reduces the frictional resistance during the rolling process and protects the surface of the roll material from scratch damage, but also transmits the pressure more evenly to the bonding interface between the roll material and the substrate, further improving the bonding strength and waterproof effect.

[0048] During use (operation), the operator holds handle 103 and pushes the device forward along the laying direction. The waterproof membrane 12 is guided downward by guide roller 13 and unfolded. The flame gun 31 uniformly heats the bottom surface of the membrane between guide roller 13 and transverse pressure roller 9 through dispersion box 141 and parallel spray holes 142, causing the modified asphalt to melt. Barrier baffle 14 concentrates the heat in the heating area to prevent heat loss and flame spread. The molten membrane is initially pressed onto the base layer by transverse pressure roller 9, and then the laid membrane is longitudinally and reciprocally rolled by vertical roller 4 driven by reciprocating mechanism to fully remove air bubbles and ensure that the membrane is tightly bonded to the base layer, forming a continuous and uniform waterproof layer.
