Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of waterproof membrane processing, and more specifically, to a waterproof membrane coating mechanism. Background Technology

[0002] In the production of waterproof membrane rolls, oiling is a crucial step in improving the waterproof performance and enhancing adhesion during installation. It requires ensuring the membrane surface is clean and free of dust and impurities before applying the oil evenly. Finally, the oil must be dried and cured to form a stable film. These three consecutive steps are essential to guarantee the quality of the oiling and the performance of the finished membrane. However, with increasing production capacity and quality requirements for waterproof membrane rolls, the shortcomings of traditional oiling methods have become increasingly apparent: current waterproof membrane oiling generally employs a step-by-step operation mode, making it impossible to simultaneously perform surface cleaning, oiling, and drying. This severely restricts production efficiency and oiling effectiveness, making it difficult to adapt to the needs of large-scale production.

[0003] Traditional oiling processes require multiple pieces of equipment and numerous steps: First, the surface of the membrane needs to be dusted and cleaned manually or with specialized equipment. After cleaning, the membrane is transferred to the oiling equipment for grease application. After oiling, it needs to be transferred to a drying area (or allowed to air dry). Throughout this process, the multiple transfers of the membrane can easily cause secondary contamination. When the cleaned membrane is transferred to the oiling stage, the surface is prone to re-adhesion of workshop dust, resulting in poor adhesion between the grease and the membrane, and easy peeling of the oil film during later use. Furthermore, the distinct intervals between the steps mean that if the grease is not dried promptly after application, uneven grease thickness can occur due to accumulation, affecting the waterproofing consistency of the membrane. Simultaneously, multiple steps require multiple pieces of equipment and manual monitoring, increasing equipment and labor costs, extending the production cycle due to transfers and waiting, and reducing overall capacity.

[0004] Therefore, the development of a waterproof membrane coating mechanism that can simultaneously perform surface cleaning, coating, and drying has become an urgent need to optimize production processes, ensure coating quality, and increase production capacity. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a waterproof membrane coating mechanism, which solves the technical problem that the existing waterproof membrane coating generally adopts a step-by-step operation mode, and cannot simultaneously perform surface cleaning, coating and drying.

[0006] According to one aspect, at least one embodiment of this disclosure provides a waterproof membrane coating mechanism, comprising: The box body and the uprights, wherein the uprights are fixed to both ends of the top of the box body; A dust removal assembly is mounted on the housing. An oiling and drying assembly is disposed between the vertical plates; The oiling and drying assembly includes a support roller disposed at one end of the top of the housing. A lower pressure roller is rotatably connected inside the housing, and a pair of oiling pressure rollers are rotatably connected inside the housing, with the oiling pressure rollers located on the side and bottom of the lower pressure roller, respectively.

[0007] As a further technical solution, an electrically driven pull-out roller is provided at the upper end between the upright plates, and an outer frame is provided on one side of the box body. A pair of feed rollers are rotatably connected inside the outer frame, one of which is electrically driven to rotate.

[0008] As a further technical solution, a pair of cavity plates are fixedly connected between the upright plates. The inner surface of the cavity plate is an inclined structural surface, and a number of air holes are opened on the inner side surface of the cavity plate. An air inlet pipe is provided on the side surface of one of the upright plates, and the air inlet pipe is connected to the pair of cavity plates.

[0009] According to another aspect, in at least one embodiment of the present invention, the dust removal assembly includes an outer cover, the outer cover is fixed to the upper end of one side of the housing, a horizontal opening is provided on the side surface of the outer cover, the outer cover is located outside the support roller, and a connecting pipe is provided on the side surface of the outer cover.

[0010] As a further technical solution, the outer cover has a hollow structure inside, and several long air inlets are opened on both inner surfaces of the outer cover. The cross-section of the outer cover has a V-shaped structure.

[0011] As a further technical solution, a liquid replenishment pipe and a liquid outlet pipe are respectively provided on the two sides of the box.

[0012] As a further technical solution, a number of heating tubes are installed inside the cavity plate, and the heating tubes are located in the lower half of the cavity plate.

[0013] As a further technical solution, both the pull-out roller and the feed roller have anti-slip structural surfaces.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure solves the problem of secondary contamination of roll materials caused by traditional step-by-step dust removal by using a dust removal component. The V-shaped outer cover forms a closed space, which not only prevents dust raised during dust removal from escaping outwards, but also forces the roll material to pass through the dust removal stage through the horizontal opening, preventing uncleaned roll material from directly entering the coating layer; the hollow outer cover, together with the high-pressure airflow introduced through the connecting pipe, blows out evenly from the long air blowing ports on the inner two surfaces, and the airflow covers the entire width of the roll material, with no dead corners for dust removal, which can thoroughly remove surface dust, fibers and other impurities, preventing them from mixing into the coating layer and affecting adhesion.

[0015] This design eliminates the need to transfer the roll material to specialized dust removal equipment. After dust removal, it can directly enter the oiling process, avoiding secondary dust accumulation on the roll material during transportation. This lays a clean foundation for subsequent uniform oiling, ensuring the waterproof performance and oil film adhesion of the waterproof roll material after oiling. At the same time, it reduces manual intervention, improves pretreatment efficiency, and adapts to the continuous production rhythm of roll materials. Attached Figure Description

[0024] like Figures 1-3 As shown, it illustrates a waterproof membrane coating mechanism according to an embodiment of the present disclosure, comprising: The box body 1 and the upright plate 2 are fixed to both ends of the top of the box body 1; Dust removal component 4 is disposed on the housing 1; Oiling and drying assembly 3 is disposed between the vertical plates 2; The oiling and drying assembly 3 includes a support roller 3-1, which is located at one end of the top of the housing 1. A lower pressure roller 3-2 is rotatably connected inside the housing 1. A pair of oiling pressure rollers 3-3 are rotatably connected inside the housing 1. The oiling pressure rollers 3-3 are located on the side and bottom of the lower pressure roller 3-2, respectively. An electrically driven pull-out roller 3-4 is provided at the upper end between the vertical plates 2. An outer frame 3-5 is provided on one side of the housing 1. A pair of delivery rollers 3-6 are rotatably connected inside the outer frame 3-5. One of the delivery rollers 3-6 is electrically driven to rotate. A pair of cavity plates 3-7 are fixedly connected between the vertical plates 2. The inner surface of the cavity plate 3-7 is an inclined structure surface. Several air holes 3-8 are opened on the inner side surface of the cavity plate 3-7. An air inlet pipe 3-9 is provided on the side surface of one of the vertical plates 2. The air inlet pipe 3-9 is connected to the pair of cavity plates 3-7.

[0025] In some examples, to achieve integrated operation of waterproof membrane from conveying, applying oil to drying, and to avoid coating damage or untimely drying caused by the need for separate transfer to drying equipment after traditional oiling, an oiling and drying assembly 3 is designed. This assembly includes a support roller 3-1 at one end of the top of the housing 1, which is the first guide component of the membrane entry mechanism. It forms a conveying cooperation with the pressure roller 3-2 rotatably connected inside the housing 1. After the waterproof membrane is conveyed from the outside to the surface of the support roller 3-1, it smoothly enters the inner cavity of the housing 1 under the guidance of the support roller 3-1 and the limiting action of the pressure roller 3-2, avoiding deviation or wrinkles during the conveying of the membrane, and laying the foundation for the uniformity of subsequent oiling. The rotation direction of the pressure roller 3-2 needs to be coordinated with the support roller 3-1 to ensure that the membrane is conveyed forward at a stable speed. The conveying speed can be synchronously adjusted by subsequent power components (such as the pull-out roller 3-4 and the delivery roller 3-6) to prevent the membrane from accumulating or stretching inside the housing 1. A pair of oiling pressure rollers 3-3, rotatably connected inside housing 1, are located on the side and bottom of the lower pressure roller 3-2, respectively, forming the core execution structure for oiling the roll material. The surface of the oiling pressure rollers 3-3 needs to be soaked in oil (which can be supplied through the oil stored in housing 1 or an external oiling pipeline). When the roll material passes through the oiling pressure rollers 3-3, the two oiling pressure rollers 3-3 apply appropriate pressure from different sides of the roll material (or different positions on the same side), so that the oil is evenly adhered to the surface of the roll material. At the same time, the pressure can expel air bubbles in the coating and enhance the adhesion between the oil and the roll material substrate. The spacing of the oiling pressure rollers 3-3 can be adjusted according to the thickness of the roll material to ensure that waterproof roll materials of different thicknesses can obtain a uniform oil coating thickness, avoiding the situation where the oil coating is too thin and the protection is insufficient due to excessive spacing, or the oil coating is too thick and the drying is slow due to excessive spacing. The upper end between the vertical plates 2 is connected to a pair of feed rollers 3-6 inside the outer frame 3-5 on one side of the box body 1 by an electrically driven pull-out roller 3-4. The pull-out roller 3-4 can smoothly transport the oiled roll material inside the box body 1 to the drying area between the vertical plates 2. The electric drive ensures that the pull-out speed matches the oiling speed of the roll material. Among the pair of feed rollers 3-6 inside the outer frame 3-5, one is rotated by electric drive and the other moves accordingly. The two work together to transport the dried roll material to the next process (such as winding), realizing the continuity of the entire oiling and drying process.

[0026] A pair of cavity plates 3-7 are fixedly connected between the vertical plates 2. The inclined structural surface of the cavity plates 3-7 can guide the airflow to converge on the surface of the roll material. Several air holes 3-8 are evenly distributed on the inner side of the cavity plates 3-7. After the air inlet pipe 3-9 of one vertical plate 2 is connected to the cavity plate 3-7, hot air (or dry air) can be introduced into the cavity plate 3-7. The hot air is evenly blown from the air holes 3-8 onto the surface of the oiled roll material. The drying process is completed simultaneously during the roll material transportation process, avoiding dust adhesion or coating runoff caused by the oil layer being in a wet state for a long time. The inclined structural surface can also reduce airflow diffusion, improve heat utilization, and ensure uniform drying effect, which is suitable for the production requirements of rapid shaping after the waterproof roll material is coated.

[0027] like Figures 1-3 As shown in the figure, the dust removal component 4 in this embodiment includes an outer cover 4-1, which is fixed to the upper end of one side of the housing 1. A horizontal opening 4-2 is provided on the side surface of the outer cover 4-1. The outer cover 4-1 is located outside the support roller 3-1. A connecting pipe 4-3 is provided on the side surface of the outer cover 4-1. The interior of the outer cover 4-1 is a hollow structure. Several long air blowing ports 4-4 are provided on both inner surfaces of the outer cover 4-1. The cross-section of the outer cover 4-1 is a V-shaped structure.

[0028] In some examples, to achieve surface dust removal pretreatment of the waterproof membrane before it enters the oiling stage, and to prevent dust and impurities adhering to the membrane surface from mixing into the oiling layer, which would lead to a decrease in oiling adhesion and damage to the waterproof performance of the membrane, a dust removal component 4 is designed. This component includes an outer cover 4-1 fixed to the upper side of one side of the housing 1, and covering the outside of the support roller 3-1 to form a closed protective space for membrane dust removal. The horizontal opening 4-2 on the side surface of the outer cover 4-1 is the membrane entry and exit channel, through which the membrane enters. After passing through the outer cover 4-1, the material needs to be guided by the support roller 3-1 before entering the housing 1. This design ensures that the roll material must undergo dust removal treatment inside the outer cover 4-1 before entering the oiling area, preventing untreated roll material from directly entering the oiling process. The outer cover 4-1 has a V-shaped cross-section, which allows the airflow to converge inside the cover, preventing airflow diffusion and dust removal dead zones. At the same time, the V-shaped side walls can prevent dust raised during the dust removal process from escaping outward, preventing secondary pollution of the roll material or the surrounding environment. The outer cover 4-1 has a hollow structure inside. The connecting pipe 4-3 on its side surface can be connected to an external air source (such as a compressed air source or a hot air source) to form an airflow supply channel. High-pressure airflow (or dry airflow) is introduced into the hollow outer cover 4-1 through the connecting pipe 4-3. The airflow can be blown out evenly from several long air blowing nozzles 4-4 opened on the two inner surfaces of the outer cover 4-1. The distribution direction of the long air blowing nozzles 4-4 must be perpendicular to (or at a certain angle to) the conveying direction of the roll material to ensure that the airflow can directly act on the surface of the roll material. The several long air blowing nozzles 4-4 are evenly distributed along the width direction of the roll material, which can cover the entire width of the roll material and avoid incomplete dust removal in some areas due to incomplete airflow coverage. It is especially suitable for the dust removal needs of wide-width waterproof roll materials. During operation, an external air source supplies air into the hood through connecting pipe 4-3. The airflow blows from the long air inlet 4-4 onto the surface of the roll material, blowing away dust, fibers, and other impurities adhering to the surface. Since the outer hood 4-1 is closed, the blown-away impurities will be concentrated at the bottom of the hood under the action of the airflow (a dust exhaust port can be added for regular cleaning), or discharged through a preset exhaust channel with the airflow, preventing impurities from re-adhering to the roll material. A valve (not shown) can be added to connecting pipe 4-3 to control the airflow pressure and flow rate: for roll materials with more surface impurities, increase the airflow pressure to enhance the dust removal effect; for roll materials with more fragile surfaces, reduce the airflow pressure to avoid damaging the roll material substrate.

[0029] For example, such as Figures 1-2 As shown, a liquid replenishment pipe 5 and a liquid outlet pipe 6 are respectively provided on the two sides of the box body 1.

[0030] In some examples, the replenishment pipe 5 and the outlet pipe 6 on both sides of the housing 1 serve the functions of replenishing the coating and discharging waste coating, respectively, forming a replenishment and cleaning channel for the coating circulation inside the housing 1. The replenishment pipe 5 needs to be connected to the external coating storage equipment, and the coating replenishment rate can be controlled by a valve. When the coating liquid level inside the housing 1 drops due to the consumption of the coating pressure roller 3-3, new coating liquid is replenished in time through the replenishment pipe 5 to ensure that the coating pressure roller 3-3 is always fully wetted with coating liquid, and to avoid uneven coating of the roll material due to insufficient coating liquid.

[0031] For example, such as Figure 3 As shown, a number of heating tubes 7 are installed inside the cavity plate 3-7, and the heating tubes 7 are located in the lower half of the cavity plate 3-7.

[0032] In some examples, several heating tubes 7 installed in the lower half of the cavity plate 3-7 are embedded and tightly fitted to the inner wall of the cavity plate 3-7, forming a secondary heating structure for the airflow. When the heating tubes 7 are energized, they release heat to assist in heating the airflow entering the cavity plate 3-7 through the intake pipe 3-9, compensating for heat loss during airflow transportation and ensuring that the airflow blown out from the air hole 3-8 has a stable and compliant temperature.

[0033] For example, such as Figure 3 As shown, the surfaces of the pull-out roller 3-4 and the feed roller 3-6 are both anti-slip structural surfaces.

[0034] In some examples, the anti-slip structure on the surfaces of the delivery rollers 3-4 and 3-6 employs an integrally molded diamond pattern or a design encased in an oil-resistant rubber layer, ensuring a tight fit with the roller surface and eliminating the risk of detachment. This anti-slip structure significantly increases the friction between the roller and the roll material surface, preventing the roll material from slipping during transport due to the smoothness of the oil coating.

[0035] In actual use: First, replenish the coating oil into the box 1 through the replenishment pipes 5 on both sides of the box 1, and periodically discharge the waste coating oil through the outlet pipe 6 to ensure the cleanliness of the coating oil; connect the connecting pipe 4-3 of the dust removal component 4 outer cover 4-1 to the external air source, connect the air inlet pipe 3-9 on the side of the vertical plate 2 to the hot air supply equipment, and start the heating pipe 7 in the cavity plate 3-7 for preheating. The waterproof membrane enters from the horizontal opening 4-2 on the side surface of the outer cover 4-1, and the long air blowing ports 4-4 on the two inner surfaces of the V-shaped outer cover 4-1 blow out high-pressure airflow to completely remove dust and impurities from the surface of the membrane, preventing dust from entering subsequent stages with the membrane; after dust removal, the membrane is guided by the support roller 3-1 and enters the box smoothly under the limiting action of the lower pressure roller 3-2 in the box 1. A pair of coating pressure rollers 3-3 (located on the side and bottom of the lower pressure roller 3-2 respectively) apply appropriate pressure from different positions of the membrane through the surface-wetted coating oil, so that the coating oil is evenly adhered to the surface of the membrane and the coating air bubbles are discharged; After being coated with oil, the roll material is conveyed by the electrically driven conveyor roller 3-4 between the vertical plates 2 to the cavity plates 3-7. The inclined structural surface inside the cavity plates 3-7 guides the hot air to converge on the roll material. The airflow heated by the heating pipe 7 is blown evenly onto the roll material through the air holes 3-8, and drying is completed simultaneously during the conveying process. Finally, the dried roll material is conveyed to the next process by the electrically driven delivery roller 3-6 (with an anti-slip structural surface to prevent slippage) inside the outer frame 3-5. No manual transfer is required throughout the process, and surface cleaning, oiling and drying are carried out simultaneously.
