Description

Technical Field

[0001] This utility model relates to the field of building waterproofing construction equipment, and in particular to a waterproof membrane laying machine. Background Technology

[0002] Waterproof membrane, as a core material in building roof waterproofing projects, is widely used in the construction of waterproof layers for various building roofs. Through high-temperature combustion, the adhesive layer on the surface of the membrane melts, forming a tight bond with the roof substrate, effectively reducing laying gaps and improving the sealing and durability of the waterproof layer. Traditional roof waterproofing construction requires manual heating with a handheld flame gun to locally melt the membrane, which is inefficient, highly susceptible to human error, and makes it difficult to guarantee uniform laying quality.

[0003] With technological advancements, existing waterproofing installation equipment has evolved from single flame guns to integrated, automated installation machines. These machines typically employ a continuous conveying system for rolled waterproofing membranes. As the membrane passes through the heating zone, a built-in flame gun melts the adhesive layer of the membrane at high temperatures, allowing it to immediately contact the ground for installation. This integrated equipment significantly improves construction efficiency and reduces the difficulty of manual operation, making it the mainstream equipment for current roof waterproofing construction.

[0004] However, existing equipment still has significant technical shortcomings. Current mainstream technologies mostly use asphalt-based adhesives, which release toxic and harmful gases containing benzo[a]pyrene and polycyclic aromatic hydrocarbons during the high-temperature melting process. Especially during large-area continuous paving operations, the high-temperature environment exacerbates the volatilization and diffusion of these harmful gases, directly posing a threat to the health of construction workers and potentially polluting the surrounding environment. Traditional equipment's ventilation and exhaust systems struggle to effectively control the concentration of toxic gases, resulting in substandard environmental quality at construction sites and posing occupational health and safety hazards. Therefore, technological innovation is urgently needed to solve these problems. Utility Model Content

[0005] In order to overcome the safety hazards posed by harmful gases, this utility model provides a waterproof membrane laying machine, which aims to solve the above-mentioned shortcomings.

[0006] A waterproof membrane laying machine includes a laying machine and a pin. The laying machine is equipped with a placement frame for placing the waterproof membrane and a high-temperature component for heating the waterproof membrane. The laying machine is equipped with a smoke extractor located on top of the high-temperature component. A filter canister is slidably connected to the top of the smoke extractor. The smoke extractor and the filter canister are stably connected by the pin. A threaded sleeve is provided in the middle of the exhaust pipe for connecting the smoke extractor and the filter canister. The exhaust pipe is located on the left and right sides of the filter canister. The middle of the exhaust pipe is separated and connected by the threaded sleeve. An exhaust cover fitted on the top of the filter canister has several through holes. An air intake component for auxiliary air intake is provided inside the smoke extractor.

[0007] Furthermore, the air intake assembly includes a drive shaft, a motor is mounted on the side of the smoke extractor, the drive shaft rotatably connected to the smoke extractor is connected to a bevel gear, a number of fan blades are installed inside the smoke extractor, the top of the fan blades is connected to the bevel gear, and the fan blades and the drive shaft are connected by the bevel gear.

[0008] Furthermore, the top of the smoke extractor is rotatably connected to a spline, the exhaust pipe passes through the side wall of the filter barrel and is connected to a vertically arranged stirring shaft, the stirring shaft is connected to the exhaust pipe, the bottom of the stirring shaft is connected to the spline, the bottom of the spline is connected to the bevel gear, the spline is connected to the drive shaft through the bevel gear, and the stirring shaft is connected to several air outlet pipes, with holes at the bottom of the air outlet pipes.

[0009] Furthermore, the smoking device is connected to sliding sleeves on both sides, the tiling machine is connected to a sliding plate, the sliding sleeves are slidably connected to the sliding plate, and the insert plate engages the sliding sleeves and the sliding plate.

[0010] Furthermore, rubber pads are provided on the left and right sides of the filter barrel, and the threaded sleeve is pressed and fitted with the rubber pads.

[0011] Furthermore, an inclined guide plate is connected to the bottom of the smoke extractor, which gathers the airflow drawn in by the fan blades to the lower end of the exhaust pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The interference fit between the pin and the sliding plate forms a tight connection structure, which effectively prevents the filter barrel and the smoke extractor from separating accidentally during equipment operation, thereby preventing the leakage of harmful gases and improving operational safety.

[0014] 2. By combining the built-in power unit and the guide plate in the exhaust duct, a directional airflow path is formed, which actively draws in and accelerates the gas generated by melting into the filtration system, reducing the diffusion of harmful gases in the working environment and lowering the risk of personnel exposure.

[0015] 3. Through the bevel gear transmission structure between the fan blades and the drive shaft, a 90-degree steering transmission is achieved, which optimizes the spatial layout while ensuring efficient power transmission. The high-speed rotation of the fan blades generates a negative pressure environment, which forces the molten gas into the smoke extractor, reducing the need for manual intervention and improving the efficiency of exhaust gas collection.

[0016] 4. The spline is connected to the stirring shaft by a parallel key to achieve synchronous rotation, which makes the gas outlet pipe evenly agitated in the solvent, promotes full contact between gas and liquid, improves the absorption efficiency of harmful substances, and ensures stable waste gas purification effect.

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example: A waterproof membrane laying machine, such as Figures 1-3 As shown, the system includes a laying machine 1, a fume extractor 2, a filter barrel 9, an exhaust pipe 10, a threaded sleeve 11, an exhaust cap 14, a pin 15, and an air inlet assembly. The laying machine 1 is equipped with a placement frame for placing waterproof membrane and a high-temperature assembly for heating the waterproof membrane. The laying machine 1 is equipped with a fume extractor 2 located on top of the high-temperature assembly. The filter barrel 9 is slidably connected to the top of the fume extractor 2. The fume extractor 2 and the filter barrel 9 are stably connected by a pin 15. The pin 15 and the bottom round hole of the filter barrel 9 are interference-fitted to ensure a tight connection. The exhaust pipe 10, which connects the fume extractor 2 and the filter barrel 9, is equipped with a threaded sleeve 11 in the middle. The exhaust pipe 10 is located on the left and right sides of the filter barrel 9. The middle of the exhaust pipe 10 is separated and connected by the threaded sleeve 11. The exhaust pipe 10 has a built-in power device that can actively draw in air. It works with the guide plate 19 to form a directional airflow path, improving the efficiency of exhaust gas collection. The exhaust cap 14, which is fitted on the top of the filter barrel 9, has several through holes. The fume extractor 2 is equipped with an air inlet assembly to assist in drawing in air.

[0023] like Figure 2 and Figure 3As shown, the air intake assembly includes a motor 4, a drive shaft 5, a bevel gear 6, and fan blades 7. The motor 4 is installed on the side of the smoke extractor 2. The drive shaft 5, which is rotatably connected inside the smoke extractor 2, is connected to the bevel gear 6. Several fan blades 7 are installed inside the smoke extractor 2. The top of the fan blades 7 is connected to the bevel gear 6. The fan blades 7 and the drive shaft 5 are connected by a 90-degree rotation transmission through the bevel gear 6, which optimizes the spatial layout while ensuring efficient power transmission.

[0024] like Figure 2 and Figure 3 As shown, it also includes a spline 8, a stirring shaft 12, and an exhaust pipe 13. The top of the smoke extractor 2 is rotatably connected to the spline 8. The exhaust pipe 10 passes through the side wall of the filter barrel 9 and is connected to the vertically arranged stirring shaft 12. The stirring shaft 12 is connected to the exhaust pipe 10. The bottom of the stirring shaft 12 is connected to the spline 8 by a flat key to achieve synchronous rotation, ensuring that there is no relative displacement when the exhaust pipe 13 stirs the solvent. The bottom of the spline 8 is connected to a bevel gear 6. The spline 8 is connected to the drive shaft 5 by the bevel gear 6. Several exhaust pipes 13 are distributedly connected to the stirring shaft 12. The bottom of the exhaust pipe 13 has an opening.

[0025] like Figure 1 and Figure 2 As shown, it also includes a sliding sleeve 3, a sliding plate 17, and an insert plate 18. The left and right sides of the smoke extractor 2 are connected to the sliding sleeve 3, and the laying machine 1 is connected to the sliding plate 17. The sliding sleeve 3 is slidably connected to the sliding plate 17, and the insert plate 18 is snapped into the sliding sleeve 3 and the sliding plate 17. The sliding sleeve 3 and the sliding plate 17 are connected by a linear guide rail, and the insert plate 18 is used to achieve quick positioning and locking.

[0026] like Figure 2 As shown, it also includes a rubber pad 16. Rubber pads 16 are provided on the left and right sides of the filter barrel 9. The threaded sleeve 11 is squeezed and fitted with the rubber pad 16. The rubber pad 16 is squeezed by the threaded sleeve 11 and undergoes elastic deformation to form a sealing interface to effectively prevent gas leakage.

[0027] like Figure 2 As shown, it also includes a guide plate 19. The bottom of the smoke extractor 2 is connected to an inclined guide plate 19. The guide plate 19 gathers the airflow drawn in by the fan blade 7 to the lower end of the exhaust pipe 10. The tilt angle of the guide plate 19 is optimized by fluid dynamics to reduce airflow resistance and accelerate airflow convergence.

[0028] The waterproof film roll enters the high-temperature component area through the placement frame. The flame continuously melts the surface layer of the waterproof film roll, at which point the motor 4 and exhaust pipe 10 are simultaneously activated. Motor 4 drives the drive shaft 5 to rotate, which in turn drives the fan blades 7 to rotate at high speed through the meshing of the bevel gear 6, creating a negative pressure environment that draws in air from the bottom of the smoke extractor 2 along with the gas generated from the melting process. The guide plate 19 is inclined, guiding the drawn-in airflow along a specific path to accelerate and converge into the exhaust pipe 10. The air is then transported through the exhaust pipe 10 into the inner cavity of the stirring shaft 12, and finally escapes evenly from the opening at the bottom of the exhaust pipe 13. When the drive shaft 5 rotates, it drives the spline 8 to rotate synchronously through the bevel gear 6. The stirring shaft 12 and the exhaust pipe 13 are connected by a key to achieve synchronous rotation, ensuring that the exhaust gas entering the filter barrel 9 is evenly dispersed in the solvent. As the exhaust gas flows upward from the bottom of the filter barrel 9, the solvent continuously adsorbs harmful substances, and the purified air is discharged through the through-hole of the exhaust cap 14. During the rotation of the exhaust pipe 13, the solvent is agitated, promoting uniform mixing of the solution and ensuring stable absorption efficiency of the exhaust gas by the surrounding solvent.

[0029] When replacing a roll of waterproof membrane with a new one, the operator first pulls out the insert plate 18 to release the sliding sleeve 3 from the sliding plate 17. Then, the operator lifts the sliding sleeve 3 upwards, causing it to slide along the sliding plate 17 and raise the entire smoke extractor 2 to the appropriate height. The insert plate 18 is then inserted again to lock the smoke extractor 2 in place. At this point, the high-temperature component area is fully exposed, facilitating the installation of the new membrane through the high-temperature component. After the new membrane is installed, the smoke extractor 2 is slowly lowered and re-secured to ensure the equipment is back in working order.

[0030] When the solution in filter tank 9 becomes saturated and needs to be replaced, the operator first pulls out all the pins 15 to release the fixing of filter tank 9, loosens the threaded sleeve 11 to separate the exhaust pipe 10 from filter tank 9, at which point the rubber gasket 16 is released from its compressed state. Then, the operator lifts filter tank 9 upwards to detach its bottom from the smoke extractor 2, at which point the bottom of the stirring shaft 12 automatically separates from the spline 8. After removing the vent cap 14, the old solution inside is completely poured out and the residue inside the tank is cleaned. New solvent is then added, and the vent cap 14 is replaced. The bottom of the stirring shaft 12 is aligned with the spline 8, and the filter tank 9 is rotated until the hole of the pin 15 coincides with the bottom round hole. The pin 15 is inserted to lock the position of filter tank 9. Finally, the threaded sleeve 11 is tightened to ensure a tight seal between the end and the rubber gasket 16 on the side of filter tank 9, ensuring airtightness and structural stability at the connection.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
