Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane laying machines, and in particular to a hot-melt auxiliary laying machine for roof waterproof membranes. Background Technology

[0002] As a key material in roof waterproofing systems, roofing waterproofing membranes utilize various construction techniques to apply different types of adhesives, ensuring their ability to withstand expansion and contraction caused by structural vibrations and temperature changes. These membranes mainly include three series: traditional bitumen waterproofing membranes, polymer-modified bitumen waterproofing membranes, and synthetic polymer waterproofing membranes. With their lightweight, superior waterproofing performance, and good flexibility, these membranes effectively protect buildings from rainwater damage.

[0003] A hot-melt assisted bonding machine, also known as a roof waterproofing welding machine or waterproof membrane hot-melt equipment, is a mechanical device specifically designed for hot-melt bonding of waterproof membranes. This equipment mainly consists of a heating plate, a temperature control system, construction tools, and accessories. Its working principle is based on heating the interface between the membrane and the substrate, promoting adhesion between the two; this process is called hot-melt bonding. Roof waterproofing welding machines significantly improve welding efficiency, shorten manual operation time, and thus accelerate project progress. At the same time, this equipment ensures welding quality during the welding process, reducing leakage problems caused by welding defects.

[0004] During the installation of waterproofing membrane, manually adjusting its position and spreading requires significant time and manpower. This not only increases construction costs but may also reduce efficiency. Because the membrane covers a large area, manual adjustments are prone to errors, affecting the waterproofing effect.

[0005] Natural cooling is used to allow the waterproofing membrane to reach a certain degree of curing, a process that typically takes a long time. This not only extends the construction period but can also lead to uneven curing due to external factors such as weather, thus affecting the overall performance of the waterproofing layer. Especially in high or low temperature environments, the natural cooling time is further extended, posing even greater challenges to the construction process.

[0006] The combination of manual adjustment and natural cooling methods means that construction quality largely depends on the experience and skill level of the construction workers. Different operating habits and quality awareness among construction workers can lead to inconsistencies in construction quality, thereby affecting the durability and reliability of the waterproofing layer. Utility Model Content

[0007] The main purpose of this utility model is to provide a hot-melt auxiliary laying machine for roof waterproof membrane, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A roof waterproofing membrane hot-melt assisted laying machine includes a support frame, side supports, a servo motor and a transmission assembly, and a laying roller. Two side supports are installed on one side of the lower end of the support frame, the laying roller is installed on the two side supports, the servo motor is installed on the side supports, and the servo motor is connected to the laying roller through the transmission assembly to realize the driving of the laying roller.

[0010] The lower end of the support frame is connected to a roll material storage cylinder via a first bearing assembly. The roll material storage cylinder contains waterproof roll material to be laid, and the waterproof roll material to be laid extends onto the laying roller.

[0011] The laying roller is mounted on the side support via a second bearing assembly. A fixed bracket is mounted on the upper end of the side support, and a shield is mounted on the lower end of the fixed bracket. The shield covers the side wall of the laying roller, and the side wall of the shield is provided with a hot air system interface. One end of the laying roller is connected to a cooling system interface.

[0012] As an optional solution of this application, the two side supports are bolted to the support frame, and anti-slip pads are provided at the connection. The side supports are bolted to the second bearing assembly, and the shafts at both ends of the laying roller are inserted into the second bearing assembly.

[0013] As an optional solution of this application, the laying roller is provided with a serpentine cooling pipe inside the roller, one end of the serpentine cooling pipe extends to the rotating shaft of the laying roller and is connected to the cooling system interface, and the fixed bracket is installed on the side bracket by bolts, and anti-slip pads are provided at the connection.

[0014] As an optional solution of this application, the cross-section of the shield is designed in the shape of a "C". The hot air system interface is inserted into the shield and connected to multiple nozzles inside the shield. Hot air is sprayed onto the laying roller through the hot air system interface and nozzles.

[0015] As an optional solution of this application, the first bearing assembly is fixed to the support frame by bolts, and the two ends of the roll storage tube are provided with rotating shafts, which are inserted into the first bearing assembly. The roll storage tube is designed in the shape of an "I".

[0016] As an optional embodiment of this application, the transmission assembly includes a large gear, a small gear, and a transmission chain. The small gear is mounted on the output end of the servo motor, the large gear is fixed to the shaft of the laying roller by bolts, and the large gear and the small gear are connected by the transmission chain.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The installation mechanism utilizes a servo motor and transmission components to efficiently drive the installation rollers, ensuring that the roofing membrane is laid evenly and stably on the roof surface. This efficient installation method not only improves work efficiency but also guarantees installation quality, allowing the membrane to adhere tightly to the roof and reducing the risk of leaks.

[0019] The roll material feeding mechanism, through the design of the roll material storage cylinder and the first bearing assembly, allows the roll material to extend smoothly onto the laying roller, ensuring the continuity and efficiency of the laying operation. Meanwhile, the "I"-shaped design of the roll material storage cylinder is both aesthetically pleasing and practical, facilitating the placement and replacement of the roll material by operators.

[0020] The introduction of a ventilation system (i.e., a hot air system and a cooling system) enables the heat-melting treatment of the roofing membrane and the cooling protection of the application rollers. The hot air system evenly sprays air onto the application rollers through multiple nozzles within a shield, heating the membrane and gradually softening it to achieve a heat-melting effect. The cooling system, on the other hand, cools the application rollers through serpentine cooling pipes within the rollers, effectively reducing their temperature and preventing damage from high temperatures. Under the dual effects of heat melting and cooling, the membrane can be firmly applied to the roof, further improving the waterproofing effect. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4As shown, a roofing waterproofing membrane hot-melt assisted laying machine comprises a robust support frame 1, two carefully designed side supports 4, a precision servo motor 5, a transmission assembly 6, and a laying roller 10. The two side supports 4 are precisely mounted on one side of the lower end of the support frame 1, ensuring the stability of the overall structure. The laying roller 10 is cleverly mounted on the two side supports 4 to facilitate the laying of the membrane. To achieve efficient driving of the laying roller 10, the servo motor 5 is mounted on the side supports 4 and tightly connected to the laying roller 10 via the transmission assembly 6, ensuring high efficiency in the laying operation.

[0028] The other side of the lower end of the support frame 1 is connected to the roll material storage cylinder 2 via the first bearing assembly 3. The roll material storage cylinder 2 contains a large amount of waterproof roll material 13 to be laid. These waterproof roll materials 13 can be smoothly extended onto the laying roller 10, ensuring the continuity and efficiency of the laying operation. The laying roller 10 is mounted on the side bracket 4 via the second bearing assembly 11, further enhancing its stability and durability.

[0029] A fixed bracket 7 is installed at the upper end of the side support 4, while a shield 9 is installed at the lower end of the fixed bracket 7. The shield 9 effectively covers the side wall of the laying roller 10 to prevent heat loss during the hot-melt process and protect the safety of the operator. A hot air system interface 8 is provided on the side wall of the shield 9, through which the hot air system can be tightly connected to the laying roller 10 to achieve the hot-melt treatment of the roll material. A cooling system interface 12 is connected to one end of the laying roller 10 to ensure that the laying roller 10 is not damaged by high temperature during the hot-melt process.

[0030] To further enhance the stability and safety of the equipment, two side supports 4 are bolted to the support frame 1, and anti-slip pads are installed at the connection points. The side supports 4 are bolted to the second bearing assembly 11, ensuring the stability of the shafts at both ends of the laying roller 10. The laying roller 10 has serpentine cooling pipes inside, one end of which extends to the shaft of the laying roller 10 and is connected to the cooling system interface 12, thereby achieving effective cooling of the laying roller 10.

[0031] The fixed bracket 7 is bolted to the side bracket 4, and anti-slip pads are installed at the connection points to ensure its stability. The shield 9 has a "C"-shaped cross-section, and the hot air system interface 8 extends into the shield 9 and connects to multiple nozzles inside the shield 9. Through the hot air system interface 8 and the nozzles, hot air can be evenly sprayed onto the laying roller 10 to ensure the heat-melting effect of the roll material.

[0032] The first bearing assembly 3 is fixed to the support frame 1 by bolts. The roll material storage cylinder 2 has rotating shafts at both ends, which are inserted into the first bearing assembly 3, allowing the roll material storage cylinder 2 to rotate flexibly. The roll material storage cylinder 2 is designed in an "I" shape, which is both aesthetically pleasing and practical. The transmission assembly 6 includes a large gear, a small gear, and a transmission chain. The small gear is mounted on the output end of the servo motor 5, and the large gear is fixed to the rotating shaft of the laying roller 10 by bolts. The large gear and small gear are tightly connected by the transmission chain, thus achieving a highly efficient transmission effect.

[0033] The operator places the waterproof membrane roll 13 to be laid into the membrane storage cylinder 2. The servo motor 5 is started, and it drives the laying roller 10 to rotate via the transmission assembly 6. The membrane roll smoothly extends from the storage cylinder 2 onto the laying roller 10, and as the roller 10 rotates, the membrane roll is evenly laid on the roof surface. During the laying process, the operator can adjust the speed of the servo motor 5 as needed to achieve different laying speeds.

[0034] Before laying the roofing membrane, it needs to undergo a heat-melting process. The operator connects the hot air system to the laying roller 10 via hot air system interface 8. Once the hot air system is activated, hot air is evenly sprayed onto the laying roller 10 through multiple nozzles within the shield 9, heating the membrane. As the laying roller 10 rotates, the membrane gradually heats up and softens, achieving the heat-melting effect. To ensure the laying roller 10 is not damaged by high temperatures during the heat-melting process, a cooling system is used to cool it via cooling system interface 12. The cooling liquid in the cooling system circulates within the serpentine cooling pipes of the laying roller 10, effectively reducing its temperature. Through the combined effects of heat melting and cooling, the membrane is firmly laid on the roof, achieving a highly efficient waterproofing effect.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
