Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project. The main products are asphalt waterproof membranes, which are made of polyester fiber as the base and formed by impregnation with asphalt.

[0027] Existing waterproof membrane surface coating devices suffer from uneven coating and insufficient oil penetration during the oiling process, resulting in substandard membrane quality and defects. Although existing technologies incorporate scrapers to recover excess oil, oil waste still exists, especially during the coating process where excess oil cannot be effectively recycled.

[0028] To address the aforementioned technical problems, this application provides a waterproof membrane surface coating device that can uniformly apply oil to the waterproof membrane, allowing the oil to penetrate the waterproof membrane and improve its quality. When some areas of the waterproof membrane are substandard, the waterproof membrane surface coating device can repeatedly process the waterproof membrane until the oil coating quality meets the standards.

[0029] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-6 A more detailed description is provided of the waterproof membrane surface coating device provided in this application.

[0030] This application provides a waterproof membrane surface coating device, which includes: a support component 1, including a base plate 11, a first support element 12 and a second support element 13, the first support element 12 and the second support element 13 being arranged opposite to each other in the length direction of the base plate 11; a winding component, including a first winding roller 21 and a second winding roller 22, the first winding roller 21 being disposed on the first support element 12 and the second winding roller 22 being disposed on the second support element 13; a coating component 3, disposed on the base plate 11 and located between the first support element 12 and the second support element 13, including a coating groove recessed from its upper surface to its lower surface; a compression limiting component 4, disposed on the coating component 3; and a power component 5, disposed on the support component 1, driving the first winding roller 21 and the second winding roller 22 to rotate in opposite directions.

[0031] Specifically, the waterproof membrane surface coating device includes a support component 1, a winding component, a coating component 3, an extrusion limiting component 4, and a power component 5. The support component 1 is used to support the entire device and ensure structural stability. The support component 1 includes a base plate 11, a first support element 12, and a second support element 13. The first support element 12 and the second support element 13 are located at both ends of the base plate 11 along its length, ensuring that the device remains stable during operation, reducing vibration and displacement, and improving coating accuracy. The winding component includes a first winding roller 21 and a second winding roller 22, which are respectively mounted on a first support element 12 and a second support element 13. The first winding roller 21 is used to release the waterproof membrane to be coated with oil, and the second winding roller 22 is used to wind the waterproof membrane after coating with oil. The power component 5 is mounted on the support component 1 and drives the first winding roller 21 and the second winding roller 22 to rotate in opposite directions, so as to realize continuous coating and winding of the membrane, reduce manual intervention, improve production efficiency, and the winding and coating of the waterproof membrane are carried out simultaneously, avoiding the tedious steps of multiple processing in traditional processes. When some areas of the waterproof membrane are unqualified, the power component 5 drives the first winding roller 21 and the second winding roller 22 to move in opposite directions, which can repeatedly process the waterproof membrane until the coating quality of the waterproof membrane meets the standard. The coating component 3 is located between the base plate 11, the first support element 12, and the second support element 13. The coating component 3 is equipped with a coating tank for storing and uniformly coating oily substances. An extrusion limiting component 4 is installed on the coating component 3 to control the coating thickness and ensure uniform coating, preventing excessive or insufficient waterproof coating. This device, through the coordinated operation of the support, winding, coating, extrusion limiting, and power components 5, achieves efficient and uniform coating of waterproof membranes, making it suitable for the production of waterproof materials.

[0032] Furthermore, this device is not only suitable for coating waterproof membranes, but can also be used for other materials that require surface coating treatment, demonstrating high versatility.

[0033] In some optional embodiments, the coating component 3 includes a coating body 31, a first baffle 32 and a second baffle 33. The first baffle 32 and the second baffle 33 are disposed on the sides of the coating body 31 that extend in its own length direction and are opposite in the width direction. The distance between the upper surface and the lower surface of the coating body 31 gradually increases after the length direction of the coating body 31 gradually decreases.

[0034] Specifically, the first baffle 32 and the second baffle 33 are disposed on the side of the paint body 31 in the width direction, which can effectively restrict the flow of paint in the width direction, prevent paint from overflowing or unevenly distributed, ensure that paint only flows in the set area, and improve the utilization rate and coating accuracy of paint.

[0035] Optionally, the coating body 31 forms a coating groove structure similar to "wave" and "gradient" in its own length direction. This structure can automatically adjust the thickness of the coating according to the movement speed of the roll and the fluidity of the coating to achieve a gradient coating effect from thin to thick and then back to thin. For example, the coating thickness is reduced at the beginning and end of the roll and increased in the middle part to meet diverse process requirements.

[0036] Optionally, the distance between the upper and lower surfaces of the paint body 31 gradually decreases and then gradually increases along its length. This design forms a V-shaped paint tank structure. The sloping design of the V-shaped paint tank allows the paint to naturally converge towards the bottom center under gravity, resulting in smoother flow and preventing paint from stagnating or accumulating in the tank, effectively reducing paint residue. The V-shaped design also allows the paint to flow concentratedly to the bottom center, reducing paint residue on the tank walls and minimizing paint waste. The sloping design of the V-shaped tank helps air bubbles and impurities in the paint to naturally rise and gather at the edge of the tank, preventing air bubbles and impurities from mixing into the coating layer and improving the quality of the paint application.

[0037] In some optional embodiments, the extrusion limiting component 4 includes a limiting roller 41, which is rotatably connected to the first baffle 32 and the second baffle 33 respectively, and is located in the area where the upper and lower surfaces of the coating component 3 are at the minimum distance.

[0038] Specifically, the area with the minimum distance between the upper and lower surfaces of the coating component 3 is the center area at the bottom of the V-shaped groove. The limiting roller 41 is rotatably connected to the first baffle 32 and the second baffle 33, maintaining stable pressure during the movement of the roll material. This ensures uniform distribution of the coating material across the width of the roll material, preventing coating accumulation or uneven thickness. The limiting roller 41, positioned at the center of the bottom of the V-shaped groove, precisely controls the flow rate and coating thickness of the coating, improving the accuracy and consistency of the coating process and enhancing the coating effect. The squeezing action of the limiting roller 41 not only controls the coating thickness but also smooths the surface of the roll material, eliminating air bubbles and impurities in the coating, improving the surface quality of the roll material. It can also scrape off excess coating material, allowing it to flow back into the coating tank, reducing coating waste.

[0039] In some optional embodiments, the extrusion limiting component 4 further includes a first extrusion component 42 and a second extrusion component 43, which are respectively connected to the first baffle 32 and the second baffle 33. The first extrusion component 42 is located in the region where the distance between the upper surface and the lower surface of the coating body 31 gradually decreases in the length direction of the coating component 3, and the second extrusion component 43 is located in the region where the distance between the upper surface and the lower surface of the coating component 3 gradually increases in the length direction of the coating component 3.

[0040] Specifically, the first extrusion component 42 is located in the area where the distance between the upper and lower surfaces of the coating body 31 gradually decreases. It applies pressure to the roll material during the initial stage of coating flow, initially controlling the coating thickness. Applying pressure during this initial stage guides the coating to distribute evenly, preventing coating accumulation or localized over-thickness on the roll surface. The second extrusion component 43 is located in the area where the distance between the upper and lower surfaces of the coating body 31 gradually increases. It further adjusts the coating thickness during the later stage of coating flow, ensuring uniform coating. During this later stage, it performs secondary extrusion on the roll material, further smoothing the coating surface, eliminating air bubbles and impurities, and improving coating quality. By adjusting the position and pressure of the first and second extrusion components 42 and 43, production needs for different coating thicknesses and roll material types can be flexibly adapted.

[0041] In some optional embodiments, the first extrusion component 42 and the second extrusion component 43 have the same structure. The first extrusion component 42 includes a fixed frame 421, a fixed roller 422, an extrusion roller 423, a movable support 424, a first spring 425, and a sliding rod 426. The bottom of the fixed frame 421 is disposed on the paint body 31. The sliding rod 426 is inserted into the first spring 425. One end of the sliding rod 426 is disposed on the top of the fixed frame 421. The other end of the sliding rod 426 passes through the first spring 425 and is connected to the movable support 424. The extrusion roller 423 is rotatably connected to the movable support 424. The fixed roller 422 is rotatably connected to the fixed frame 421.

[0042] Specifically, the roll material passes between the extrusion roller 423 and the fixed roller 422. The extrusion roller 423 and the fixed roller 422 contact the surface of the waterproof roll material, and the coating is evenly extruded by the elastic pressure of the first spring 425 to avoid coating accumulation or excessive thickness in some areas. One end of the sliding rod 426 is set at the top of the fixed frame 421, and the other end of the sliding rod 426 passes through the first spring 425 and is connected to the movable bracket 424. This allows the extrusion roller 423 to automatically adjust the pressure according to the thickness of the roll material and the flowability of the coating. When the thickness of the roll material is uneven or the flow of the coating changes, the extrusion roller 423 adaptively adjusts its position through the elasticity of the spring to ensure a consistent coating thickness. The elastic pressure of the extrusion roller 423 on the waterproof roll material can smooth the surface of the roll material, eliminate air bubbles and impurities in the coating, and improve the surface quality of the roll material. The elastic pressure of the extrusion roller 423 can scrape off excess coating and return it to the coating tank, reducing coating waste. The rotating connection between the extrusion roller 423 and the movable bracket 424, and the rotating connection between the fixed roller 422 and the fixed frame 421, allow the roll material to pass through smoothly.

[0043] In some optional embodiments, the limiting roller 41 includes a fixed shaft 411 and a rotating roller 412, the fixed shaft 411 passes through the rotating roller 412, the fixed shaft 411 is connected to the first baffle 32 and the second baffle 33 respectively, and the rotating roller 412 is provided with an anti-slip groove 4121.

[0044] Specifically, the anti-slip grooves 4121 on the surface of the rotating roller 412 increase the friction with the surface of the roll material, ensuring close contact between the roll material and the rotating roller 412, avoiding surface defects caused by slippage, and preventing the roll material from slipping during high-speed operation. This is particularly suitable for roll materials with smooth surfaces, ensuring the continuity and stability of the coating process, improving the tight contact between the waterproof roll material and the rotating roller 412, and improving the uniformity of coating. The fixed shaft 411 is set on the first baffle 32 and the second baffle 33, and the rotating roller 412 is rotatably connected to the fixed shaft 411, making the contact between the roll material surface and the coating more uniform, avoiding uneven coating caused by unstable movement of the waterproof roll material, reducing frictional resistance with the waterproof roll material, eliminating air bubbles and impurities in the coating, and improving the surface quality of the roll material.

[0045] In some alternative embodiments, a fan 6 is also included, which is disposed on the first baffle 32 and the second baffle 33.

[0046] Specifically, fan 6 can accelerate the airflow on the surface of the coating by blowing air, which promotes the rapid curing and drying of the coating. It is especially suitable for coatings that require rapid curing and can significantly shorten the production cycle. By accelerating the curing of the coating, the roll material can enter the next process more quickly, reducing waiting time and improving overall production efficiency.

[0047] Optionally, the fan 6 is disposed in the region between the first support element 12 and the first extrusion member 42, and in the region between the second support element 13 and the second extrusion member 43.

[0048] In some optional embodiments, the first take-up roller 21 and the second take-up roller 22 have the same structure. The first take-up roller 21 includes a take-up roller body 211, a rotating shaft 212, a fixing buckle 213, a telescopic rod 214 and a second spring 215. The telescopic rod 214 is rotatably connected to the first support element 12. The other end of the telescopic rod 214 passes through the second spring 215 and is connected to the fixing buckle 213. The take-up roller body 211 is fixedly connected to the fixing buckle 213 and the rotating shaft 212 respectively. The rotating shaft 212 is rotatably connected to the first support element 12.

[0049] Furthermore, a limiting plug 2121 is provided at one end of the rotating shaft 212 that is connected to the take-up roller body 211, and a limiting hole 2111 is provided at the other end of the take-up roller body 211 that is connected to the rotating shaft 212. The limiting plug 2121 is inserted into the limiting hole 2111, thereby connecting the rotating shaft 212 and the take-up roller body 211 together.

[0050] Specifically, the second spring 215 can extend and retract along the telescopic rod 214, allowing the take-up roller body 211 to automatically adjust its position according to the tension of the roll material. When the tension of the roll material changes, the telescopic rod 214 adjusts its position adaptively through the elasticity of the second spring 215, ensuring that the roll material maintains a stable tension during the winding process.

[0051] In some alternative embodiments, the power unit 5 includes a drive unit 51 and a transmission unit 52, the drive unit 51 driving the transmission unit 52, and the transmission unit 52 connecting the rotation shaft 212 of the first take-up roller 21 and the rotation shaft 212 of the second take-up roller 22.

[0052] Specifically, the transmission component 52 connects the rotating shafts 212 of the first take-up roller 21 and the second take-up roller 22, and the drive component 51 synchronously drives the two take-up rollers to rotate in opposite directions through the transmission component 52. This design ensures uniform tension of the roll material during winding and unwinding, avoiding deformation, wrinkling, or uneven coating caused by uneven tension. The combined design of the drive component 51 and the transmission component 52 simplifies the power transmission structure, reduces the number of parts, and lowers the complexity and maintenance costs of the equipment. The drive component 51 can be a motor, which can precisely control the speed and direction of rotation. The synchronous reverse rotation of the first take-up roller 21 and the second take-up roller 22 is achieved through the transmission component 52, improving the automation level and operational accuracy of the equipment. The synchronous drive of the first take-up roller 21 and the second take-up roller 22 by the transmission component 52 reduces the fluctuation of the waterproof roll material during movement and improves the coating quality.

[0053] In some optional embodiments, the transmission component 52 includes a first transmission shaft 521, a second transmission shaft 522, a transmission gear assembly 523, a first conveyor belt 524, a second conveyor belt 525, a third conveyor belt 526, and a fourth conveyor belt 527. The first transmission shaft 521 is disposed on the first support element 12, the second transmission shaft 522 is disposed on the second support element 13, the first conveyor belt 524 connects the first transmission shaft 521 and the rotation shaft 212 of the first take-up roller 21, the second conveyor belt 525 connects the first transmission shaft 521 and the transmission gear assembly 523, the transmission gear assembly 523 is disposed on the paint body 31, the third conveyor belt 526 connects the transmission gear assembly 523 and the second transmission shaft 522, and the fourth conveyor belt 527 connects the second transmission shaft 522 and the rotation shaft 212 of the second take-up roller 22.

[0054] Specifically, the transmission gear assembly 523 includes two meshing transmission gear shafts. One transmission gear shaft includes a third transmission shaft 5231 and a first gear 5232. One end of the third transmission shaft 5231 is connected to the coating body 31, and the other end is provided with the first gear 5232. The other transmission gear shaft includes a fourth transmission shaft 5233 and a second gear 5234. The fourth transmission shaft 5233 is connected to the coating body 31, and the other end is provided with the second gear 5234. The first gear 5232 meshes with the second conveyor belt 525, and the other second gear 5234 meshes with the third conveyor belt 526. The transmission gear assembly 523 is the core component for power distribution and can precisely adjust the speed and direction of the first take-up roller 21 and the second take-up roller 22 to avoid tension fluctuations in the roll material caused by uneven power distribution. The first drive shaft 521 is disposed on the first support element 12, the second drive shaft 522 is disposed on the second support element 13, and the transmission gear assembly 523 is disposed on the paint body 31. The transmission gear assembly 523 is located in the middle position between the first drive shaft 521 and the second drive shaft 522. The power is evenly distributed to the first take-up roller 21 and the second take-up roller 22 to ensure that the two rotate synchronously in opposite directions.

[0055] The first conveyor belt 524 connects the first drive shaft 521 and the rotating shaft 212 of the first take-up roller 21. The second conveyor belt 525 connects the first drive shaft 521 and the transmission gear assembly 523. The third conveyor belt 526 connects the transmission gear assembly 523 and the second drive shaft 522. The fourth conveyor belt 527 connects the second drive shaft 522 and the rotating shaft 212 of the second take-up roller 22, forming a multi-stage transmission system that efficiently transmits the power of the drive component 51 to the first take-up roller 21 and the second take-up roller 22. The multi-stage transmission design optimizes the power transmission path, reduces power loss, and improves the stability and reliability of the transmission.
