[0002] In building waterproofing projects, the laying of waterproof membranes is a key step to ensure the waterproof performance of buildings. Traditional waterproof membrane laying mainly relies on manual operation, which has problems such as low construction efficiency, unstable quality, and high labor intensity. With the development of technology, automatic laying equipment has gradually become an important means to improve construction efficiency and quality. However, some existing automatic laying equipment still has some shortcomings in practical applications, which limits its widespread promotion and use.

[0003] Chinese invention patent CN113958075B discloses an automatic laying device for waterproofing coiled materials, including a bottom plate, a rotating shaft, a material taking ring, a material storage plate, a discharging mechanism and a connecting mechanism. By setting the discharging mechanism, the waterproofing coiled materials can be stably output, and the waterproofing coiled materials are connected by using the connecting mechanism, so as to realize automatic laying of the waterproofing coiled materials, greatly reduce the amount of manual work, and ensure the connection stability of the waterproofing coiled materials. The device mainly focuses on the stable output and connection of the coiled materials, but lacks detailed design in the spraying and heating treatment of the adhesive, resulting in an unsatisfactory bonding effect between the coiled materials and the base surface, lacks precise control of the temperature, and is prone to poor bonding or overheating due to uneven temperature.

Through the cooperation of these components, the laying speed and quality are improved, the bulging problem caused by the laying of coiled materials is solved, flame burns are prevented, and safe construction is ensured. Although the device improves the laying speed and quality, it still has shortcomings in uniform spraying and multi-point heating of the adhesive, especially the poor adaptability in complex environments. Although the design of the gas spray gun solves the problem of flame burns, it fails to make full use of the residual heat after combustion, resulting in energy waste. There is a lack of intelligent control system and it cannot be automatically adjusted according to real-time temperature feedback, which affects the construction quality. Summary of the invention

[0006] The objective of the present invention is achieved through the following technical solutions: an automatic laying device for modified asphalt waterproofing membrane, comprising a controller and a combustion box, one end of the combustion box is fixedly connected to a hot melt box, the hot melt box is connected to a plurality of mass transfer rods by a ball joint at an end away from the combustion box, the plurality of mass transfer rods are fixedly connected to the same nozzle at one end away from the hot melt box, a waste heat pipe is fixedly connected to the top of the combustion box, a heating nozzle is fixedly connected to the end of the waste heat pipe away from the combustion box, the bottom end of the heating nozzle is fixedly connected to the top end of the nozzle, the outer end of the mass transfer rod located between the hot melt box and the nozzle is connected to an adjustment plate by a ball joint, the top of the hot melt box is fixedly connected to an adjustment motor, the outer end of the adjusting motor shaft is rotatably connected to an eccentric block, the adjustment plate is rotatably connected to the eccentric block, and the eccentric block is eccentrically mounted on the adjusting motor On the power shaft, the combustion box and the top of the hot melt box are fixedly connected to the same material box, a heating tube is wound on the outer end, the bottom end of the heating tube is connected to one end of the combustion box through waste heat tube 2, the end of the combustion box close to waste heat tube 2 is fixedly connected to waste heat tube 3, the end of waste heat tube 3 away from the combustion box is rotatably connected to a heating roller, the heating roller is a hollow structure, and an exhaust port is provided at the end of the heating roller away from waste heat tube 3, the outer end of the heating roller is arranged in contact with the coil to be laid, a plurality of non-contact temperature sensors are fixedly connected to one end of the nozzle close to the heating roller, and the plurality of temperature sensors are electrically connected to the controller, the regulating motor is electrically connected to the controller, the top of the material box is connected to the external air pressure system through a pipeline, and the external air pressure system is electrically connected to the controller, and the material box is filled with adhesive.

[0007] By setting up multiple mass transfer rods and nozzles, combined with the multi-point heating mechanism of heating nozzles and heating rollers, it is ensured that the adhesive can be sprayed evenly on the surface of the coil, and the bonding strength between the coil and the base surface is enhanced through physical extrusion to avoid the generation of bonding gaps at the joints. Through the multi-level waste heat pipeline design, the heat of the exhaust gas after combustion is recovered, the gas consumption is reduced, and the operating cost is reduced. In particular, the introduction of heat exchange fins further improves the heat exchange efficiency, shortens the preheating time, and saves energy. The combination of non-contact temperature sensors and regulating motors realizes real-time monitoring and automatic adjustment of the coil surface temperature, ensuring that the adhesive and hot air can be evenly distributed, avoiding poor bonding due to uneven temperature. Or overheating problems, through the cooperation of the roller and the drive motor, the automatic transportation of the coil is realized, ensuring the speed and accuracy of the coil laying. The drive motor is electrically connected to the controller, and can accurately control the rotation speed of the roller according to actual needs, avoiding laying problems caused by uneven speed. The design of the roller makes the installation and replacement of the coil more convenient and improves construction efficiency. Through the efficient heat recovery mechanism, it significantly reduces exhaust emissions, meets modern environmental protection requirements, and the optimized combustion process also helps to reduce the generation of pollutants and promote the development of green buildings. The application of non-contact temperature sensors reduces direct contact with the coil, avoids possible pollution or damage, and further improves environmental protection performance.

[0008] One end of the combustion box away from the waste heat pipe is connected with a gas bottle through a pipeline, and the outer end of the gas bottle is fixedly connected with the combustion box through a bracket.

[0009] Both ends of the combustion box are fixedly connected to side brackets, and a reel is rotatably connected to the upper side of the material box between the two side brackets. The outer end of the reel is wound with the coiled material to be laid, and the bottom end of the material box is connected to the hot melt box through two pipes.

[0010] The two side brackets are both rotatably connected to the heating roller, both ends of the heating roller pass through the side brackets, and the passing parts are fixedly connected with side pressure wheels, and the diameter of the side pressure wheels is larger than the diameter of the heating roller.

The outer ends of the two side brackets are located between the heating roller, the reel and the roller and are rotatably connected to a handle for operation.

[0012] A plurality of heat exchange fins are fixedly connected to the inner wall of the combustion box near the hot melt box, and a fixing plate for fixing the mass transfer rod is fixedly connected to the end of the hot melt box away from the mass transfer rod by bolts.

[0013] The connection between the outer end of the mass transfer rod and the hot melt box and the adjustment plate is a spherical structure, and the diameter of the spherical structure at the connection with the hot melt box is larger than the diameter at the connection with the adjustment plate.

[0014] The mass transfer rod connects the hot melt box and the nozzle. Both the nozzle and the heating nozzle are hollow triangular structures, and nozzles are provided at one end of the nozzle and the heating nozzle close to the heating roller. A solenoid valve is provided between the combustion box and the gas cylinder. Solenoid valves are fixedly connected to the waste heat pipe 1, the waste heat pipe 2 and the waste heat pipe 3 of Huawei, and multiple solenoid valves are electrically connected to the controller.

[0015] The beneficial effects of the present invention are: 1. The present invention realizes efficient recovery and reuse of the heat of waste gas after combustion through the design of multiple waste heat pipelines. The high-temperature waste gas in the combustion box enters the heating pipe through the waste heat pipe 2 to continue heating the material box to ensure that the adhesive always maintains appropriate fluidity. At the same time, part of the waste gas enters the heating nozzle through the waste heat pipe 1 and is ejected from the nozzle to preheat the bottom end of the coil to help the adhesive adhere better. Another part of the waste gas enters the heating roller through the waste heat pipe 3 to heat it to ensure that the coil is evenly preheated during the laying process. This multi-level waste heat utilization mechanism significantly reduces gas consumption, reduces operating costs, and improves energy utilization efficiency.

[0016] In addition, the heat exchange fins installed inside the combustion box further improve the heat exchange efficiency, shorten the preheating time, and further save energy. The overall design not only reduces gas consumption, but also reduces exhaust emissions, meeting modern environmental protection requirements.

[0017] 2. The present invention adopts a combination of a non-contact temperature sensor and an adjusting motor to realize real-time monitoring and automatic adjustment of the surface temperature of the coil. The temperature sensor continuously monitors the temperature changes on the surface of the coil and feeds the data back to the controller. Based on these data, the controller can dynamically adjust the working state of the adjusting motor and change the angle of the nozzle to ensure that the adhesive and hot air are evenly distributed. This precise temperature control mechanism avoids poor bonding or overheating caused by uneven temperature and significantly improves the construction quality.

[0018] The fine control of the solenoid valve also ensures the rational distribution of gas and avoids unnecessary energy waste. The controller can accurately control the heat input of each part according to actual needs and optimize the overall performance of the system. Especially in large-area waterproofing projects, this intelligent adjustment mechanism can significantly improve construction efficiency and quality.

[0019] 3. The mass transfer rod adopts a spherical structure connection, which not only ensures flexibility but also increases structural strength, avoiding mechanical failures caused by frequent adjustments. The combined design of the heating roller and the side pressure wheel not only provides uniform preheating for the coil, but also enhances the bonding strength between the coil and the base surface through physical extrusion, avoiding the generation of bonding gaps at the joints.

[0020] The solenoid valve design between the gas bottle and the combustion box ensures the safety of gas supply and prevents accidental leakage or excessive gas supply. The electrical connection design between the controller and various sensors and actuators ensures the stability and reliability of the system and avoids construction problems caused by temperature fluctuations or mechanical failures. The presence of the handle also increases the flexibility of the equipment, allowing the operator to make fine adjustments at any time according to the on-site conditions, thereby improving the safety and convenience of construction.

[0021] 4. The present invention ensures the speed and accuracy of coiled material laying through the cooperation of the drum and the drive motor. The drive motor is electrically connected to the controller and can accurately control the rotation speed of the drum according to actual needs, thus avoiding laying problems caused by uneven speed. The design of the drum makes the installation and replacement of the coiled material more convenient and improves the construction efficiency. Especially in large-area waterproofing projects, this design greatly shortens the preparation time and improves the overall construction progress.

[0022] The combined design of the heating roller and the side pressure wheel not only provides uniform preheating for the coil, but also enhances the bonding strength between the coil and the base surface through physical extrusion, avoiding the generation of bonding gaps at the joints. This multi-point heating and extrusion mechanism significantly improves construction efficiency and quality, and is particularly suitable for construction in complex environments.

[0023] 5. The present invention significantly reduces exhaust gas emissions through an efficient heat recovery mechanism, which meets modern environmental protection requirements. The optimized combustion process also helps to reduce the generation of pollutants and promote the development of green buildings. The application of non-contact temperature sensors reduces direct contact with the coil, avoids possible pollution or damage, and further improves environmental protection performance.

[0024] In addition, by making full use of the waste heat after combustion, the present invention effectively reduces gas consumption and carbon emissions, which is in line with the concept of sustainable development. The overall design not only improves construction efficiency, but also reduces the impact on the environment, and has significant environmental advantages.

[0025] 6. The present invention ensures that the coil is fully preheated and evenly bonded during the laying process by heating the coil multiple times in all directions. The heating nozzle and the nozzle heat the coil and spray the adhesive from the bottom and top respectively, ensuring that the adhesive can cover the surface of the coil more evenly. The additional squeezing of the coil edge by the side pressure wheel ensures good bonding at the coil joint and avoids the generation of bonding gaps.

[0026] The heated roller physically squeezes the coil during movement, allowing the coil to better adhere to the surface that needs waterproofing. This multi-point heating and squeezing mechanism significantly improves the construction quality and is particularly suitable for the requirements of high-quality waterproofing projects.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0031] Embodiment 1: like Figures 1 to 12 As shown, this embodiment provides an automatic laying device for modified asphalt waterproofing membrane, whose main components include a controller, a combustion box 1, a hot melt box 2, a plurality of mass transfer rods 3, a nozzle 4, a waste heat pipe 1 5, a heating nozzle 6, an adjustment plate 7, an adjustment motor 8, a material box 9, a heating pipe 10, a waste heat pipe 2 11, a waste heat pipe 3 12, and a gas cylinder 14. The device is designed for efficiently laying modified asphalt waterproofing membrane and realizing efficient use of energy by making full use of the waste heat after combustion.

[0032] The combustion box 1 is the heat source part of the whole system. A plurality of heat exchange fins are installed inside to improve the heat transfer efficiency. One end of the combustion box 1 is connected to the gas bottle 14 through a pipe. The gas bottle 14 is fixed on the bracket outside the combustion box 1 to ensure stable gas supply. A solenoid valve is provided on the pipe between the gas bottle 14 and the combustion box 1, which is electrically controlled by the controller to ensure the safety and accuracy of the gas supply.

[0033] The hot melt box 2 is located on one side of the combustion box 1, and the two are closely connected to facilitate direct heat transfer. The end of the hot melt box 2 away from the combustion box 1 is connected to multiple mass transfer rods 3 by a ball joint, and the other ends of these mass transfer rods 3 are fixedly connected to the nozzle 4. This ball joint connection allows the mass transfer rod 3 and the nozzle 4 to adjust the angle as needed to ensure that the adhesive can be accurately sprayed at the desired position. The outer end of the mass transfer rod 3 is connected to the hot melt box 2 and the adjustment plate 7 in a spherical structure, and the diameter of the spherical structure at the connection with the hot melt box 2 is larger than the diameter at the connection with the adjustment plate 7, which increases the flexibility and stability of the connection.

[0034] The nozzle 4 and the heating nozzle 6 are both hollow triangular structures, and a nozzle is provided at one end close to the heating roller 13, which can evenly spray the adhesive and hot air onto the coil. The nozzle 4 is also equipped with a plurality of non-contact temperature sensors to monitor the temperature changes on the surface of the coil. These sensors are electrically connected to the controller to ensure real-time feedback of temperature information.

[0035] The adjusting plate 7 is installed on the outside of the mass transfer rod 3 and is rotatably connected to the eccentric block on the adjusting motor 8. When the adjusting motor 8 is started, it can adjust the angle of the adjusting plate 7 by changing the position of the eccentric block, thereby affecting the inclination of the mass transfer rod 3 and the nozzle 4. The adjusting motor 8 is electrically connected to the controller and can be automatically adjusted according to the feedback from the temperature sensor to ensure that the adhesive can be sprayed more accurately at the desired position.

[0036] The material box 9 is located on the top of the combustion box 1 and the hot melt box 2, and is filled with adhesive (such as modified asphalt) and is connected to the external air pressure system through a pipeline. When spraying is required, the compressed air provided by the external air pressure system will push the adhesive from the material box 9 into the hot melt box 2, and then reach the nozzle 4 through the mass transfer rod 3. The top of the material box 9 is connected to the external air pressure system through a pipeline, and the external air pressure system is electrically connected to the controller to ensure that the flow of the adhesive is controllable and stable.

[0037] The heating tube 10 is wound at the outer end, and the bottom is connected to the combustion box 1 through the waste heat pipe 11, which is used to recover the waste heat after combustion and further heat the adhesive in the material box 9. The design of the heating tube 10 not only improves the fluidity of the adhesive, but also reduces the additional heating demand and saves energy.

[0038] Waste heat pipe 1 5 and waste heat pipe 3 12 are respectively located at the top and one side of the combustion box 1. The former is connected to the heating nozzle 6, and the latter is connected to the heating roller 13. The design of these waste heat pipes allows the high-temperature gas after combustion to be reused before leaving the system, thereby improving the overall energy utilization rate. Waste heat pipe 1 5, waste heat pipe 2 11, and waste heat pipe 3 12 are all fixedly connected with solenoid valves. Multiple solenoid valves are electrically connected to the controller, and the heat input of each part can be accurately adjusted according to actual needs.

[0039] The gas bottle 14 supplies gas to the combustion box 1 through the solenoid valve control, and the solenoid valves on the waste heat pipe 1 5, the waste heat pipe 2 11, and the waste heat pipe 3 12 are also managed by the controller, and the heat input of each part can be accurately adjusted according to actual needs.

[0040] Working process Preparation: Before use, the operator needs to ensure that the gas cylinder 14 is correctly connected and filled with gas, check whether all electrical connections are working properly, confirm that the material box 9 is filled with an appropriate amount of adhesive (such as modified asphalt), and check whether the pressure of the external air pressure system is within the normal range.

[0041] Ignition and preheating: When in use, the controller first opens the solenoid valve between the gas bottle 14 and the combustion box 1, allowing the gas to flow into the combustion box 1, where it is ignited to produce a flame. The heat generated by the combustion is quickly transferred to the combustion box 1 and its surrounding components, especially the hot melt box 2 and the material box 9. At the same time, the heat exchange fins in the combustion box 1 begin to absorb heat, further improving the heat exchange efficiency and ensuring that the temperature in the hot melt box 2 and the material box 9 rises rapidly.

[0042] Adhesive melting and spraying: The adhesive in the material box 9 gradually melts into liquid after being heated. At this time, the external air pressure system is started and compressed air is injected into the material box 9, forcing the liquid adhesive to enter the mass transfer rod 3 through the hot melt box 2, and finally spray out from the nozzle 4, covering the bottom end of the coil to be laid. The mass transfer rod 3 connects the hot melt box 2 and the nozzle 4 to ensure that the adhesive can flow smoothly. The nozzle 4 and the heating nozzle 6 are both hollow triangular structures, and a nozzle is provided at the end close to the heating roller 13, which can evenly spray the adhesive and hot air onto the coil.

[0043] Waste gas utilization and secondary heating: part of the high-temperature waste gas in the combustion box 1 enters the heating tube 10 through the waste heat pipe 2 11 to continue heating the material box 9 to ensure that the adhesive always maintains appropriate fluidity. Another part of the waste gas enters the heating nozzle 6 through the waste heat pipe 1 5 and is ejected from the nozzle to preheat the bottom end of the coil to help the adhesive adhere better. Another part of the waste gas enters the heating roller 13 through the waste heat pipe 3 12 to heat it. As the heating roller 13 moves, it not only provides additional heat for the coil, but also makes the coil more firmly adhere to the base surface through physical extrusion.

[0044] Temperature monitoring and automatic adjustment: During this process, the non-contact temperature sensor on the nozzle 4 continuously monitors the temperature of the coil surface and feeds back the data to the controller. If abnormal temperature is detected, the controller will adjust the working state of the motor 8 accordingly and change the angle of the nozzle 4 to ensure that the adhesive and hot air are evenly distributed. The controller can also dynamically adjust the opening and closing degree of each solenoid valve according to the feedback from the temperature sensor, optimize the efficiency of gas use, and reduce unnecessary energy loss. When the laying task is completed, the controller will gradually close each solenoid valve, stop the gas supply and heating process, and at the same time, the external air pressure system will also stop working to ensure the safe shutdown of the equipment.

[0045] By setting up multiple waste heat pipelines, this embodiment effectively recovers the heat of the waste gas after combustion, reduces gas consumption, and reduces operating costs. For example, the waste heat pipe 2 11 and the heating pipe 10 work together to ensure that the adhesive in the material box 9 is always at a suitable working temperature; the waste heat pipe 3 12 provides a stable heat source for the heating roller 13, thereby enhancing the bonding strength between the coil and the base surface. The design of the heat exchange fins significantly improves the heat exchange efficiency, shortens the preheating time, and further saves energy.

[0046] The non-contact temperature sensor is combined with the regulating motor 8 to realize dynamic adjustment of the angle of the nozzle 4, so that the adhesive and hot air can be sprayed on the coil more evenly, thereby improving the construction quality.

[0047] The fine control of the solenoid valve also ensures the stability and reliability of the entire system, avoiding construction problems caused by temperature fluctuations or unstable gas supply. All key components such as the combustion box 1, hot melt box 2, material box 9, etc. are carefully designed to ensure long-term stable operation in a high temperature environment. In particular, the mass transfer rod 3 adopts a spherical structure connection, which not only ensures flexibility but also increases structural strength, avoiding mechanical failures caused by frequent adjustments. The solenoid valve design between the gas bottle 14 and the combustion box 1 ensures the safety of the gas supply and prevents accidental leakage or excessive gas supply.

[0048] Due to the adoption of an efficient heat recovery mechanism, this embodiment significantly reduces exhaust emissions and meets modern environmental protection requirements. At the same time, the optimized combustion process also helps to reduce the generation of pollutants and promote the development of green buildings. The application of non-contact temperature sensors reduces direct contact with the coil, avoids possible contamination or damage, and further improves environmental performance.

[0049] This embodiment realizes the efficient laying of modified asphalt waterproofing membrane by rationally configuring various components. At the same time, it greatly improves energy utilization efficiency and construction quality through waste heat recovery and intelligent control system. This equipment is not only suitable for various waterproofing projects, but also can effectively reduce operating costs and improve construction safety. It has broad application prospects. Embodiment 2: like Figures 1 to 12 As shown, based on the first embodiment, this embodiment further describes in detail the specific structure and working mode of the coil conveying and heating system. The system includes a combustion box 1, a side bracket 15, a reel 16, a heating roller 13, a side pressure wheel 17, a roller and its driving motor and other components, aiming to ensure that the coil can be laid smoothly and accurately, and to improve the construction quality through multi-point heating.

[0050] Both ends of the combustion box 1 are fixedly connected with side brackets 15, which not only provide support for the entire device, but also carry other key components.

[0051] A reel 16 is rotatably connected between the side brackets 15 and located above the material box 9. The outer end of the reel 16 is wound with the coiled material to be laid. The design of the reel 16 allows the coiled material to be easily installed and replaced, thereby improving construction efficiency.

[0052] The bottom of the material box 9 is connected to the hot melt box 2 through two pipes, ensuring that the adhesive can flow smoothly from the material box 9 into the hot melt box 2 and then reach the nozzle 4 through the mass transfer rod 3. This double-pipe design increases the stability of the adhesive flow and reduces the possibility of blockage.

[0053] Both ends of the heating roller 13 pass through the side bracket 15 and are rotatably connected to the side bracket 15. The heating roller 13 is a hollow structure, and the interior can be heated by introducing high-temperature exhaust gas through the waste heat pipe three 12. An exhaust port is provided at the end of the heating roller 13 away from the waste heat pipe three 12 to ensure uniform heat distribution.

[0054] The side pressure wheels 17 are fixedly connected to both ends of the heating roller 13 and have a diameter larger than the heating roller 13 for additionally squeezing both sides of the coil. The design of the side pressure wheels 17 helps to improve the bonding effect of the coil edge and avoid bonding gaps at the joints.

[0055] The roller is installed between two side brackets 15, away from the heating roller 13. The roller is driven by a drive motor, which is fixedly connected to the side bracket 15 and electrically connected to the controller. The drive motor can accurately control the rotation speed of the roller according to the instructions of the controller to ensure that the speed of the coil conveying is stable and controllable.

[0056] The handle is rotatably connected to the outer ends of the two side brackets 15 and is located between the heating roller 13, the reel 16 and the roller. The operator can manually adjust the position of the equipment through the handle, which is convenient for construction in complex environments.

[0057] Working process Before use, the operator needs to place the roll 16 wound with the coil to be laid between the side brackets 15, and ensure that the coil can be smoothly pulled out from the roll 16. At the same time, check whether all mechanical connections are firm and whether the electrical connections are normal, confirm that the connection between the drive motor and the controller is normal, ensure that the roller can run smoothly under the command of the controller, pull one end of the coil out from the roll 16, make it bypass the bottom end of the heating roller 13, and through the guidance of the roller, ensure that the coil can be laid along the predetermined path.

[0058] The operator can manually adjust the position of the equipment through the handle to ensure that the starting position of the coil is accurate. When the equipment is started, the controller first turns on the drive motor, which drives the roller to rotate, and the roller then pulls the coil on the reel 16 to make it move along the set path. As the coil moves, the heating roller 13 heats its bottom end. Since high-temperature exhaust gas is introduced into the interior of the heating roller 13 through the waste heat pipe 12, the coil is fully preheated when passing through the heating roller 13, which helps the subsequent adhesive spraying and the bonding of the coil. The side pressure wheel 17 performs additional squeezing on both sides of the coil to ensure that the edge of the coil can be better bonded to the coil next to it to avoid bonding gaps at the joints.

[0059] During the movement of the coil, the nozzle 4 and the heating nozzle 6 heat the coil and spray the adhesive from the bottom and top respectively. The non-contact temperature sensor on the nozzle 4 continuously monitors the temperature change on the surface of the coil and feeds back the data to the controller. The controller dynamically adjusts the working state of the motor 8 and changes the angle of the nozzle 4 according to the feedback from the temperature sensor to ensure that the adhesive and hot air are evenly distributed. At the same time, the controller can also adjust the speed of the drive motor according to actual needs to ensure that the speed of coil laying matches the speed of adhesive spraying.

[0060] When the laying task is completed, the controller will gradually shut down the drive motor and stop the conveying of the coil. At the same time, it will shut down other related components, such as the heating roller 13 and the nozzle 4, to ensure the safe shutdown of the equipment. Through the cooperation of the roller and the drive motor, this embodiment realizes the automatic conveying of the coil and ensures the speed and accuracy of the coil laying. The drive motor is electrically connected to the controller and can accurately control the rotation speed of the roller according to actual needs, avoiding laying problems caused by uneven speed.

[0061] The design of the reel 16 makes the installation and replacement of the roll material more convenient and improves the construction efficiency. Especially in large-scale waterproofing projects, this design greatly shortens the preparation time and improves the overall construction progress.

[0062] The combined design of the heating roller 13 and the side pressure wheel 17 not only provides uniform preheating for the coil, but also enhances the bonding strength between the coil and the base surface through physical extrusion. In particular, the additional extrusion of the coil edge by the side pressure wheel 17 effectively avoids the bonding gap at the joint, thus ensuring the integrity and reliability of the waterproof layer.

[0063] The high-temperature exhaust gas introduced by the waste heat pipe 3 12 provides a stable heat source for the heating roller 13, ensuring that the coil is fully preheated when passing through the heating roller 13, which helps the subsequent adhesive spraying and coil bonding, and improves the construction quality.

[0064] The handle design provides the operator with the convenience of manually adjusting the position of the equipment, which is particularly suitable for construction in complex environments or narrow spaces. Through the handle, the operator can easily adjust the position of the equipment to ensure the accuracy of the roll material laying. The presence of the handle also increases the flexibility of the equipment, allowing the operator to make fine adjustments at any time according to the on-site conditions, thereby improving the adaptability and convenience of construction.

[0065] All key components such as the side bracket 15, the winding drum 16, the heating roller 13, the side pressure wheel 17, etc. are carefully designed to ensure stability during long-term operation. In particular, the hollow structure of the heating roller 13 and the diameter design of the side pressure wheel 17 not only ensure the heating effect, but also increase the structural strength and avoid mechanical failures caused by frequent use.

[0066] The electrical connection design between the drive motor and the controller ensures the precise control of the coiled material conveying, avoids construction problems caused by speed fluctuations or mechanical failures, and improves the safety and reliability of the system. This embodiment realizes efficient and stable conveying and multi-point heating of the coiled material through reasonable mechanical design and intelligent control system, ensuring the high-quality laying of modified asphalt waterproofing coiled material. This system is not only suitable for various waterproofing projects, but also can effectively improve construction efficiency and quality, and has broad application prospects. In particular, in large-area waterproofing projects, the advantages of this embodiment are particularly obvious, which can significantly improve the construction speed and project quality. Embodiment three: like Figures 1 to 12As shown, based on the first and second embodiments, this embodiment further describes in detail the specific structure and working mode of the temperature control and regulation system of the automatic laying equipment of the modified asphalt waterproofing membrane. The system includes a controller, a combustion box 1, a hot melt box 2, a mass transfer rod 3, a nozzle 4, a heating nozzle 6, an adjustment plate 7, an adjustment motor 8, a non-contact temperature sensor, a solenoid valve and other components, and aims to ensure that the adhesive spraying and heating effects in the process of membrane laying reach the best state through precise temperature control and real-time adjustment. The controller is the center of the entire system and is responsible for coordinating the work of each component to ensure the stable operation of the system. The controller is electrically connected to multiple sensors and actuators and can monitor and adjust various parameters of the system in real time. The combustion box 1 is used as the main heat source, and multiple heat exchange fins are installed inside to improve the heat transfer efficiency. One end of the combustion box 1 is connected to the gas cylinder 14 through a pipeline. The gas cylinder 14 is fixed on the bracket outside the combustion box 1 to ensure stable gas supply. A solenoid valve is provided on the pipeline between the gas cylinder 14 and the combustion box 1, which is electrically connected and controlled by the controller to ensure the safety and accuracy of the gas supply.

[0067] The hot melt box 2 is located on one side of the combustion box 1, and the two are closely connected to facilitate direct heat transfer. The end of the hot melt box 2 away from the combustion box 1 is connected to multiple mass transfer rods 3 by a ball joint, and the other ends of these mass transfer rods 3 are fixedly connected to the nozzle 4. This ball joint connection allows the mass transfer rod 3 and the nozzle 4 to adjust the angle as needed to ensure that the adhesive can be accurately sprayed at the desired position. The outer end of the mass transfer rod 3 is connected to the hot melt box 2 and the adjustment plate 7 in a spherical structure, and the diameter of the spherical structure at the connection with the hot melt box 2 is larger than the diameter at the connection with the adjustment plate 7, which increases the flexibility and stability of the connection.

[0068] The nozzle 4 and the heating nozzle 6 are both hollow triangular structures, and a nozzle is provided at one end close to the heating roller 13, which can evenly spray the adhesive and hot air onto the coil. The nozzle 4 is also equipped with a plurality of non-contact temperature sensors to monitor the temperature changes on the surface of the coil. These sensors are electrically connected to the controller to ensure real-time feedback of temperature information.

[0069] The adjusting plate 7 is installed on the outside of the mass transfer rod 3 and is rotatably connected to the eccentric block on the adjusting motor 8. When the adjusting motor 8 is started, it can adjust the angle of the adjusting plate 7 by changing the position of the eccentric block, thereby affecting the inclination of the mass transfer rod 3 and the nozzle 4. The adjusting motor 8 is electrically connected to the controller and can be automatically adjusted according to the feedback from the temperature sensor to ensure that the adhesive can be sprayed more accurately at the desired position.

[0070] The solenoid valves are distributed between the combustion box 1 and the gas bottle 14, as well as on the waste heat pipe 1 5, the waste heat pipe 2 11, and the waste heat pipe 3 12. The multiple solenoid valves are electrically connected to the controller, and the heat input of each part can be accurately adjusted according to actual needs. The design of the solenoid valve not only ensures the reasonable distribution of gas, but also improves the safety and reliability of the system.

[0071] Working process Before use, the operator needs to ensure that the gas cylinder 14 is correctly connected and filled with gas, check whether all electrical connections are working properly, confirm that the material box 9 is filled with an appropriate amount of adhesive (such as modified asphalt), and check whether the pressure of the external air pressure system is within the normal range.

[0072] Place the roll 16 wound with the coil to be laid between the side brackets 15, and ensure that the coil can be smoothly pulled out from the roll 16, pull one end of the coil out from the roll 16, make it pass around the bottom end of the heating roller 13, and through the guidance of the roller, ensure that the coil can be laid along the predetermined path.

[0073] When in use, the controller first opens the solenoid valve between the gas bottle 14 and the combustion box 1, allowing the gas to flow into the combustion box 1, where it is ignited to produce a flame, and the heat generated by the combustion is quickly transferred to the combustion box 1 and its surrounding components, especially the hot melt box 2 and the material box 9.

[0074] At the same time, the heat exchange fins in the combustion box 1 begin to absorb heat, further improving the heat exchange efficiency and ensuring that the temperature in the hot melt box 2 and the material box 9 rises rapidly.

[0075] The adhesive in the material box 9 gradually melts into liquid after being heated. At this time, the external air pressure system is started to inject compressed air into the material box 9, forcing the liquid adhesive to pass through the hot melt box 2 into the mass transfer rod 3, and finally spray out from the nozzle 4 to cover the bottom end of the coil to be laid.

[0076] The mass transfer rod 3 connects the hot melt box 2 and the nozzle 4 to ensure that the adhesive can flow smoothly. The nozzle 4 and the heating nozzle 6 are both hollow triangular structures, and a nozzle is provided at one end close to the heating roller 13, which can evenly spray the adhesive and hot air onto the coil.

[0077] Part of the high-temperature exhaust gas in the combustion box 1 enters the heating pipe 10 through the waste heat pipe 11 to continue heating the material box 9 to ensure that the adhesive always maintains appropriate fluidity.

[0078] Another part of the exhaust gas enters the heating nozzle 6 through the waste heat pipe 5 and is ejected from the nozzle to preheat the bottom end of the coil to help the adhesive adhere better.

[0079] Another part of the exhaust gas enters the heating roller 13 through the waste heat pipe 3 12 to heat it. As the heating roller 13 moves, it not only provides additional heat for the coil, but also makes the coil more firmly adhere to the base surface through physical extrusion.

[0080] During this process, the non-contact temperature sensor on the nozzle 4 continuously monitors the temperature of the surface of the coil and feeds the data back to the controller. If abnormal temperature is detected, the controller will adjust the working state of the motor 8 accordingly and change the angle of the nozzle 4 to ensure that the adhesive and hot air are evenly distributed.

[0081] The controller can also dynamically adjust the opening and closing degree of each solenoid valve according to the feedback from the temperature sensor, optimize the efficiency of gas use, and reduce unnecessary energy loss. For example, when the temperature of a certain part of the coil is low, the controller can increase the heating intensity of that area; when the temperature is too high, the heating amount is reduced to ensure that the coil is always at the optimal construction temperature.

[0082] The adjusting motor 8 drives the adjusting plate 7 to rotate by changing the position of the eccentric block, thereby adjusting the angles of the mass transfer rod 3 and the nozzle 4. This real-time adjustment mechanism ensures that the adhesive and hot air can be sprayed more accurately at the desired position, avoiding construction problems caused by uneven temperature.

[0083] As the coil moves, the drive motor drives the roller to rotate, and the roller then pulls the coil on the reel 16 to make it move along the set path. The heating roller 13 and the side pressure wheel 17 heat and squeeze the coil to ensure that the coil can be better bonded to the base surface and avoid bonding gaps at the joints.

[0084] During the coil laying process, the nozzle 4 and the heating nozzle 6 heat the coil and spray the adhesive from the bottom and top respectively. The non-contact temperature sensor on the nozzle 4 continuously monitors the temperature changes on the coil surface and feeds the data back to the controller to ensure the construction quality.

[0085] When the laying task is completed, the controller will gradually close each solenoid valve, stop the gas supply and heating process, and at the same time, the external air pressure system will also stop working to ensure the safe shutdown of the equipment.

[0086] Through the cooperation of the non-contact temperature sensor and the controller, this embodiment realizes real-time monitoring and automatic adjustment of the surface temperature of the coil. The controller can dynamically adjust the working state of the motor 8 and change the angle of the nozzle 4 according to the feedback of the temperature sensor to ensure that the adhesive and hot air are evenly distributed. This precise temperature control mechanism significantly improves the construction quality and avoids poor bonding or overheating caused by uneven temperature.

[0087] By setting up multiple waste heat pipelines, this embodiment effectively recovers the heat of the waste gas after combustion, reduces gas consumption, and reduces operating costs. For example, the waste heat pipe 2 11 and the heating pipe 10 work together to ensure that the adhesive in the material box 9 is always at a suitable working temperature; the waste heat pipe 3 12 provides a stable heat source for the heating roller 13, thereby enhancing the bonding strength between the coil and the base surface. The design of the heat exchange fins significantly improves the heat exchange efficiency, shortens the preheating time, and further saves energy.

[0088] The fine control of the solenoid valve ensures the rational distribution of gas and avoids unnecessary energy waste. The controller can accurately control the heat input of each part according to actual needs and optimize the overall performance of the system. Especially in large-area waterproofing projects, this intelligent adjustment mechanism can significantly improve construction efficiency and quality.

[0089] The mass transfer rod 3 is connected by a spherical structure, which ensures flexibility and increases structural strength, avoiding mechanical failures caused by frequent adjustments. The combined design of the heating roller 13 and the side pressure wheel 17 not only provides uniform preheating for the coil, but also enhances the bonding strength between the coil and the base surface through physical extrusion, avoiding the generation of bonding gaps at the joints.

[0090] The solenoid valve design between the gas cylinder 14 and the combustion box 1 ensures the safety of the gas supply and prevents accidental leakage or excessive gas supply. The electrical connection design between the controller and various sensors and actuators ensures the stability and reliability of the system and avoids construction problems caused by temperature fluctuations or mechanical failures. The presence of the handle also increases the flexibility of the equipment, allowing the operator to make fine adjustments at any time according to the on-site conditions, thereby improving the safety and convenience of construction.

[0091] This embodiment realizes the efficient laying of modified asphalt waterproofing membrane through a reasonable temperature control and regulation system, ensuring that the adhesive spraying and heating effects during the construction process reach the best state. The system is not only suitable for various waterproofing projects, but also can effectively improve the construction quality and efficiency, and has a wide range of application prospects. Especially in large-area waterproofing projects, the advantages of this embodiment are particularly obvious, which can significantly improve the construction speed and project quality. At the same time, through the intelligent control system, the safety and reliability of the construction are ensured. The above is only a preferred embodiment of the present invention.
