Description

Technical Field

[0001] This utility model belongs to the technical field of waterproof membrane production equipment, specifically involving the structural optimization of waterproof membrane production equipment. Background Technology

[0002] Asphalt-based waterproof membranes are among the most widely used materials in modern building waterproofing projects, and their production process is highly mature and automated. The process can generally be summarized as follows: raw material preparation, modified bitumen preparation, base impregnation and coating, lamination, cooling and molding, and packaging. Among these, base impregnation and coating are the core processes. The base is first impregnated with modified bitumen in a tank, allowing the bitumen to fully penetrate all the gaps in the base. After impregnation, the base emerges from the tank with excess bitumen adhering to its upper and lower surfaces. This excess bitumen is then scraped away by a pair of precisely controlled scrapers, resulting in a uniformly thick and quantitatively controlled coating layer on both sides of the base.

[0003] Some production equipment has emerged in the prior art. For example, Chinese patent CN222943824U discloses an asphalt recycling structure for the production of waterproof membrane, including an asphalt frame and a recycling structure; the base fabric is conveyed to the coating process from above the first roller, below the pressure roller, above the second roller and above multiple conveying rollers. When it is below the pressure roller, asphalt is coated on the base fabric and removed from above the second roller. When the base fabric coated with asphalt passes through multiple conveying rollers, the dripping asphalt falls into the collection frame, and after being filtered by the filter plate, it falls to the bottom of the collection frame.

[0004] However, the device also has the following problems, which are the technical problems that this application aims to solve: asphalt is easily adhered to the roller, and the adhered asphalt will affect the formation of the coating layer and ultimately affect the quality of the waterproof membrane. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an integrated waterproof and anti-corrosion asphalt waterproof membrane production equipment. Through structural optimization, it aims to prevent asphalt from adhering to the scraper, ensuring uniform coating thickness and a smooth surface, thereby improving the quality of the waterproof membrane.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A waterproof and corrosion-resistant integrated bitumen waterproof membrane production equipment includes a scraper located at the upper end of the membrane, a vibration source component, and a transmission rod; the vibration source component transmits vibration to the scraper through the transmission rod, and the direction of vibration transmitted by the transmission rod is parallel to the scraped surface of the membrane.

[0007] As a further preferred embodiment of this utility model, the scraper is provided with a heating chamber, and the scraper is provided with an inlet and an outlet that are respectively connected to the heating chamber.

[0008] As a further preferred embodiment of this invention, it also includes a frame for mounting the scraper and vibration source components, and a heat dissipation component mounted on the frame for exchanging heat with the transmission rod near the scraper.

[0009] As a further preferred embodiment of the present invention, the heat dissipation component includes a cylinder movably connected to the transmission rod, a heat exchange chamber disposed within the cylinder, and an inlet and an outlet disposed on the cylinder and respectively communicating with the heat exchange chamber.

[0010] As a further preferred embodiment of this utility model, it also includes a storage tank, which is provided with an infusion pipe connected to the inlet and a first recovery pipe connected to the outlet.

[0011] As a further preferred embodiment of this invention, the storage box is also provided with a second recycling pipe connected to the output port.

[0012] As a further preferred embodiment of this utility model, both the infusion tube and the first recovery tube are provided with flexible tube sections.

[0013] As a further preferred embodiment of this utility model, it also includes a rotary joint, wherein the fixed end of the rotary joint is connected to the end of the infusion tube or the first recovery tube, and the movable section of the rotary joint is connected to the inlet or outlet.

[0014] As a further preferred embodiment of this utility model, a connecting pin is provided at the end of the transmission rod away from the vibration source component, and a connecting groove matching the connecting pin is provided on the scraper.

[0015] As a further preferred embodiment of this invention, a heat-insulating box is provided for protecting the vibration source component.

[0016] The beneficial effects of this utility model are: The production equipment provided by this invention introduces high-frequency micro-vibration parallel to the coating surface into the coating process. This vibration generates high-frequency shear between the scraper and the asphalt, completely destroying the adhesion between the asphalt and the metal surface, fundamentally solving the problem of scraper sticking. This ensures a uniform coating thickness and an extremely smooth and flat surface, significantly improving the product quality of the waterproof membrane.

[0017] The production equipment provided by this utility model, based on vibration anti-sticking, further introduces auxiliary synergistic technology of heating and heat preservation. The synergistic effect of the two can completely eliminate frequent machine shutdowns for cleaning caused by sticking to the blade, greatly improve the continuous operation time and production efficiency of the production line, and reduce labor costs and energy consumption.

[0018] The production equipment provided by this utility model fully considers the actual conditions of industrial applications. By incorporating heat dissipation components, flexible pipe sections, rotary joints, etc., it effectively solves the problems of high-temperature environment on precision vibration sources and medium transportation under vibration conditions, ensuring the long-term stability and reliability of the entire system under harsh working conditions.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, terms such as "set" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] As attached Figure 1As shown, this embodiment provides an integrated waterproof and anti-corrosion asphalt waterproof membrane production equipment, including a frame 1, a scraper 2 located at the upper end of the membrane a, a vibration source component 3, and a transmission rod 4; the vibration source component 3 transmits vibration to the scraper 2 through the transmission rod 4, and the vibration direction transmitted by the transmission rod 4 is parallel to the scraping surface of the membrane a.

[0026] The frame 1 serves as the main support for the entire device, fixed to the production line used to transport asphalt-coated roll material a. The scraper 2 is bolted to the frame 1, its cutting edge facing the moving roll material a, used to scrape off excess asphalt. The vibration source component 3 (which can be a high-frequency electromagnetic vibrator or a voice coil motor) is fixed to the frame 1 via a bracket. The output shaft of the vibration source component 3 can be connected to one end of the transmission rod 4 via any known connection structure (such as a flange). The transmission rod 4 can be made of heat-resistant alloy steel, possessing high rigidity and fatigue strength. The other end of the transmission rod 4 can be directly connected to the scraper 2, transmitting vibration to the scraper 2, or it can act indirectly on the scraper 2, causing it to vibrate through a striking effect. Preferably, a connecting pin 41 is provided at the end of the transmission rod 4 furthest from the vibration source component 3, and a connecting groove 24 matching the connecting pin 41 is provided on the scraper 2. This structure ensures effective transmission of vibration direction and allows for a certain installation error.

[0027] The vibration direction at scraper 2 is crucial. The vibration direction is parallel to the coating surface of the roll material a, rather than perpendicular or in other directions, because the parallel direction can directly overcome the shear adhesion force between the asphalt and the metal surface, making it difficult for the asphalt to stay on the scraper surface. This causes the asphalt to be sheared at high frequency between the "liquid" and "semi-solid" states, instantly increasing its fluidity and resulting in a smoother and more even coating surface. If a perpendicular direction is used, vertical vibration may produce tiny ripples on the soft asphalt coating surface that are difficult to smooth out, affecting the product's appearance and quality. Using other directions would result in an overly complex structure and low reliability in industrial settings.

[0028] It is worth noting that the connection point between the transmission rod 4 and the scraper 2 requires dynamic design to ensure that the scraper 2 can vibrate effectively and that the vibration direction is parallel to the coating surface of the roll material a. Dynamic design can be determined by those skilled in the art through multiple experiments based on common knowledge; therefore, it will not be elaborated upon in this embodiment. The vibration frequency of the vibration source component 3 should be controlled within the range of 100-500 Hz, and the amplitude within the range of 0.1-0.5 mm.

[0029] In some preferred embodiments, the scraper 2 is provided with a heating chamber 21, and the scraper 2 is provided with an inlet 22 and an outlet 23 respectively communicating with the heating chamber 21. To ensure that the scraper 2 has a suitable temperature to prevent asphalt from solidifying, the heating chamber 21 should be circulated with heat-conducting oil, with a temperature of 140-180℃ being suitable. To ensure the flowability of the heat-conducting oil, the heating chamber 21 can be designed with a suitable flow channel shape, which does not require creative effort and will not be elaborated further. Preferably, the outlet 22 should be located at the lower end near the cutting edge, and the outlet 23 should be located at the upper end away from the cutting edge.

[0030] Furthermore, as shown in the appendix Figure 2 As shown, the system also includes a storage tank 6, which is equipped with a delivery pipe 61 connected to the inlet 22 and a first recovery pipe 62 connected to the outlet 23. The storage tank 6 stores heat transfer oil, which is connected to the inlet 22 of the scraper 2 via the delivery pipe 61 and to the outlet 23 via the first recovery pipe 62, forming a complete heat transfer oil circulation loop. The loop includes an oil pump and a heater (not shown) to drive and heat the heat transfer oil. To accommodate the high-frequency vibration of the scraper 2, a flexible pipe section (such as a corrugated metal pipe) is connected in series with both the delivery pipe 61 and the first recovery pipe 62. Furthermore, a rotary joint 64 is used at the end connection of the pipes. The fixed end of the rotary joint 64 is connected to the pipe, while the movable end is connected to the inlet 22 and outlet 23 on the scraper 2. The rotary joint 64 effectively seals the fluid and adapts to high-frequency, micro-amplitude rotational oscillations, making it a key component for solving dynamic sealing problems. This component is readily available for purchase.

[0031] As some preferred embodiments, to prevent the high temperature on the scraper 2 from being conducted to the vibration source component 3 through the rigid transmission rod 4, a heat dissipation component 5 is also included, which is mounted on the frame 1 and used for heat exchange with the transmission rod 4 near the scraper 2. It is worth noting that the heat dissipation component 5 is fixed to the frame 1, thereby preventing it from exerting its own weight on the transmission rod 4 and affecting the transmission of vibration. The heat dissipation component 5 can be a commonly used structure such as a heat insulation sleeve or heat dissipation fins. One application structure in this embodiment is as follows: it includes a cylinder 51 movably connected to the transmission rod 4, a heat exchange chamber 52 disposed within the cylinder 51, and an inlet 53 and an outlet 54 disposed on the cylinder 51 and respectively communicating with the heat exchange chamber 52. The cylinder 51 has a channel through which the transmission rod 4 passes, and the heat exchange chamber 52 is recessed into the inner wall of the channel, with an additional seal designed at this inner wall to prevent leakage. The medium flowing in the heat exchange chamber 52 can be either liquid or gas. Preferably, the circulating medium can be the same heat transfer oil as that in the heating chamber 21. The low-temperature heat transfer oil (supplied by an external supply device, not shown in the figure) is introduced from the inlet 53, and after heat exchange, it is discharged from the outlet 54. The outlet 54 is connected to a second recovery pipe 63, which inputs the heat-exchanged heat transfer oil into the storage tank 6 for recovery, facilitating the absorption of residual heat. This arrangement is a more economical choice.

[0032] Furthermore, the frame 1 can also be equipped with a heat insulation box to protect the vibration source component 3, so as to provide additional heat insulation protection, ensure that the vibration source component 3 can work in a suitable and stable environment, and also avoid the vibration source component 3 being directly contaminated by asphalt.

[0033] The working principle of the production equipment provided by this utility model is as follows: During operation, the circulation system on storage tank 6 activates, heating the scraper 2 to maintain its operating temperature and prevent premature asphalt solidification. Simultaneously, the vibration source component 3 activates, generating high-frequency micro-vibrations. These vibrations are precisely transmitted to the scraper 2 via transmission rod 4, causing its cutting edge to produce a high-frequency micro-shearing motion parallel to the surface of the roll material. When the high-temperature asphalt passes over the scraper 2, the vibration effectively disrupts the adhesion between the asphalt molecules and the metal surface, preventing the asphalt from remaining on the scraper and achieving a "never sticks" effect. The heat dissipation component 5 continuously operates to protect the vibration source. The entire system works in tandem to ultimately produce a high-quality waterproof roll material with a uniform coating and a smooth surface.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
