Description

Technical Field

[0001] This utility model relates to the field of drainage board production technology, and in particular to a production equipment for a self-adhesive three-dimensional protective drainage board composite roll. Background Technology

[0002] Currently, the self-adhesive three-dimensional protective roll material for side walls on the market belongs to the category of drainage board composite roll materials. Its structure, from bottom to top, consists of HDP raised drainage board, EVA hot melt adhesive, geotextile, pressure-sensitive hot melt adhesive, and silicone oil release film. During construction, the silicone oil release film is removed, allowing the pressure-sensitive adhesive to bond with the completed SBS bitumen roll material on the side wall, thus serving as a backfill soil protection layer for the SBS roll material, replacing the traditional extruded polystyrene board protective layer.

[0003] In the existing production process, the production flow of sidewall drainage boards involves first manufacturing HDPE raised drainage boards through extrusion molding, then roller-coating EVA hot melt adhesive onto the drainage boards, followed by laminating pre-processed semi-finished geotextile and pressure-sensitive hot melt adhesive, and finally pulling and winding to obtain the finished product. The semi-finished geotextile and pressure-sensitive adhesive are pre-fabricated products purchased directly from external suppliers. Due to the presence of raised sections, these pre-fabricated semi-finished products cannot form a completely flat surface after lamination. In traditional processes, roller-coating hot melt adhesive requires a relatively flat surface to ensure even distribution and firm adhesion. Therefore, a separate production line is needed to apply pressure-sensitive hot melt adhesive to the geotextile, laminate it with a release film, and then wind it into a large semi-finished roll before subsequent production on the drainage board production line.

[0004] However, the existing production process suffers from two main drawbacks. First, it requires the external procurement of prefabricated semi-finished geotextiles coated with pressure-sensitive adhesive, resulting in high purchase prices and thus high overall production costs for the sidewall drainage boards, making them less competitive in the market. Second, the dual-production-line model complicates the production process, increasing the complexity and cost of production management. Utility Model Content

[0005] This utility model provides a production equipment for self-adhesive three-dimensional protective drainage board composite rolls for side walls. It addresses the significant shortcomings of existing technologies in the hot melt adhesive roller coating process after the drainage board product's raised areas are covered with fabric. These technologies also suffer from high production costs and cumbersome production processes. The new equipment enables the direct production of finished side wall drainage boards on existing production lines, upgrading the original two-step process into a single-step process completed on one production line. This allows for uniform coating of hot melt adhesive on uneven drainage board surfaces. Furthermore, by improving the production process, it reduces production costs, increases production efficiency, simplifies the production flow, and enhances the product's competitiveness in the market.

[0006] This utility model provides a production equipment for a self-adhesive three-dimensional protective drainage board composite roll material for side walls.

[0008] According to the production equipment of the self-adhesive three-dimensional protective drainage board composite roll material provided by this utility model, the glue spraying module further includes an online glue layer thickness gauge.

[0016] This utility model provides a production equipment for self-adhesive three-dimensional protective drainage board composite rolls for sidewalls. By integrating multiple production modules onto a single production line, it achieves a continuous production process from material extrusion to finished product winding.

Simultaneously, the real-time monitoring function of the visual inspection and imaging module can promptly detect abnormalities in the production process and control the start and stop of the spray guns in the adhesive spraying module via signal connection. This improves the continuity and stability of production, reduces production interruptions and quality problems caused by manual operation, and significantly improves production efficiency.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] The following is combined Figures 1 to 3 The production equipment for the self-adhesive three-dimensional protective drainage board composite roll provided in this utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0028] In this embodiment, as Figures 1 to 3 As shown, a production equipment 10 for a self-adhesive three-dimensional protective drainage board composite roll material for sidewalls includes a material extrusion module 100, an extrusion molding module 200, an adhesive coating and fabric covering module 300, a vision inspection and imaging module 400, an adhesive spraying module 500, a film coating module 600, and a traction and winding module 700 arranged sequentially along the production direction. The adhesive spraying module 500 includes multiple spray guns 510, which are evenly distributed along the width of the drainage board 21. 10 is used to uniformly spray adhesive onto the upper surface of the drainage board 21 after it has been covered by the adhesive coating and covering module 300; the visual inspection and imaging module 400 is located between the adhesive coating and covering module 300 and the adhesive spraying module 500. The visual inspection and imaging module 400 is connected to the adhesive spraying module 500 by signal. The visual inspection and imaging module 400 is used to detect the material information of the drainage board 21 flowing from the adhesive coating and covering module 300 to the adhesive spraying module 500 in real time, and control the start and stop of the spray gun 510 according to the material information.

[0029] The material extrusion module 100 is the starting point of production. It is used to heat and plasticize mixed granular raw materials such as HDPE, POE, and PP, and transform the raw materials into molten sheet substrates through screw extrusion, and continuously convey them to the next stage.

[0030] The extrusion molding module 200 receives the molten sheet substrate conveyed by the material extrusion module 100. Through the cooperation of the upper and lower rollers (the lower roller has a boss screw and the upper roller has a corresponding pit), the molten substrate is extruded and shaped. At the same time, the vacuum siphon system is used to adsorb and shape it, and finally a drainage plate 21 with a boss structure is formed.

[0031] The adhesive coating and fabric covering module 300 is used to realize two processes: adhesive coating and fabric covering. The adhesive coating process involves uniformly coating the surface of the protrusion of the extruded drainage board 21 with EVA hot melt adhesive 22 by roller coating to form an adhesive transition layer, which provides an adhesive foundation for the subsequent covering of the geotextile 23. The fabric covering process involves precisely covering the geotextile 23 with the drainage board 21 coated with EVA hot melt adhesive, using the adhesiveness of EVA hot melt adhesive to firmly bond the two together.

[0032] The visual inspection and imaging module 400 is located between the adhesive coating and fabric covering module 300 and the adhesive spraying module 500. The function of the visual inspection and imaging module 400 is to acquire image information of the drainage board 21 conveyed from the adhesive coating and fabric covering module 300 in real time, and to detect the material status of the drainage board 21, such as the presence or absence of material and its distance. Through analysis and judgment of this information, the module can accurately identify the position information of the drainage board 21, providing a basis for starting and stopping the subsequent adhesive spraying process.

[0033] The function of the adhesive spraying module 500 is to spray pressure-sensitive hot melt adhesive 24 onto the upper surface of the covered drainage board 21. Since the surface of the covered drainage board 21 is uneven due to the presence of protrusions, the traditional roller coating method cannot achieve uniform adhesive application. The adhesive spraying module 500 atomizes the hot melt adhesive and evenly adheres it to the uneven surface through high-pressure spraying, ensuring a consistent adhesive layer thickness and providing a reliable bonding foundation for the subsequent lamination of the release film 25.

[0034] The function of the laminating module 600 is to laminate the silicone oil release film 25 to the sprayed drainage board 21. The laminating module 600 provides the release film 25 through an unwinding mechanism, and a web-aligning device ensures that the release film 25 is aligned with the edges of the drainage board 21. Then, the pressing action of the composite rollers ensures that the release film 25 is tightly bonded to the pressure-sensitive hot melt adhesive on the surface of the drainage board 21. The release film 25 protects the pressure-sensitive hot melt adhesive from contamination during storage and transportation, and is easy to remove quickly during construction. This module completes the final structural lamination process for the finished drainage board 21.

[0035] The function of the traction and winding module 700 is to provide stable traction for the entire production line, ensuring the orderly transport of the drainage boards 21 between modules, and simultaneously winding the drainage boards 21 that have completed all composite processes into rolls of specified dimensions. The traction machine 710 ensures synchronized production rhythm between modules through stable speed control; the winding machine 720 winds the continuously produced drainage boards 21 into rolls that are easy to store, transport, and further process, serving as the final stage of the production process.

[0036] Multiple evenly distributed spray guns 510 can fully cover the wide surface of the drainage board 21 (e.g., 3 meters wide). Each spray gun 510 is responsible for spraying adhesive in a specific width area. Through coordinated work, it ensures that the entire upper surface of the drainage board 21 is evenly coated. This avoids the problems of missed coating or uneven adhesive amount caused by the limited spraying range of a single spray gun 510. It is especially suitable for the production of wide drainage boards 21, ensuring the consistency of adhesive layer thickness in different locations.

[0037] The visual inspection imaging module 400 is connected to the glue spraying module 500 via signal transmission, enabling real-time linkage between detection and execution. The visual inspection imaging module 400 can check the presence or absence of drainage boards 21 on the production line in real time to control the start and stop of the spray gun 510. Simultaneously, when an abnormality is detected in the drainage board 21 (such as damage to the geotextile 23 or deformation of the protrusions), the visual inspection imaging module 400 immediately sends a stop signal to the glue spraying module 500, causing the spray gun 510 to stop working and preventing glue waste and the generation of defective products. When the drainage board 21 is detected as acceptable, a start signal is sent, and the spray gun 510 begins spraying glue. This improves production accuracy and efficiency and reduces errors caused by manual intervention.

[0038] This application integrates multiple production modules onto a single production line, achieving a continuous production process from material extrusion to finished product winding. This reduces changeover time in the production process, enabling the direct production of the sidewall drainage board 21 on the existing production line without the need for additional equipment or production lines. The adhesive spraying module 500 includes multiple spray guns 510 evenly distributed along the width of the drainage board 21, which can spray adhesive onto the upper surface of the drainage board 21 after it has been coated by the adhesive coating module 300. Furthermore, a vision detection imaging module 400 is located between the adhesive coating module 300 and the adhesive spraying module 500, and is signal-connected to the adhesive spraying module 500. It can detect the material information of the drainage board 21 flowing towards the adhesive spraying module 500 in real time, and control the start and stop of the spray guns 510 based on this information, thereby ensuring uniform coating of hot melt adhesive even on the uneven surface of the drainage board 21. Meanwhile, the real-time monitoring function of the visual inspection imaging module 400 can promptly detect abnormalities in the production process and control the start and stop of the spray gun 510 of the glue spraying module 500 via signal connection. This improves the continuity and stability of production, reduces production interruptions and quality problems caused by manual operation, and thus significantly improves production efficiency.

[0039] Reference Figure 2 According to the production equipment 10 of the self-adhesive three-dimensional protective drainage board composite roll material provided by this utility model, the glue spraying module 500 also includes a hot melt glue machine, glue hose and pneumatic module. The hot melt glue machine is used to provide hot melt glue and is connected to the spray gun 510 through the glue hose. The pneumatic module is connected to the spray gun 510 through the pressure regulating valve 520. The pressure regulating valve 520 is used to adjust the air pressure of the spray gun 510 to control the glue spraying thickness of the spray gun 510 on the surface of the drainage board 21.

[0040] Understandably, the hot melt glue machine, as the source of hot melt glue supply, heats solid hot melt glue to a molten state, giving it good flowability and viscosity. The glue hose is the channel connecting the hot melt glue machine and the spray guns 510, accurately delivering the molten hot melt glue from the machine to each spray gun 510.

[0041] The pneumatic module provides power to the spray gun 510, driving it to spray adhesive using compressed air. The pneumatic module converts the pressure of compressed air into the spraying force of the spray gun 510, causing the hot melt adhesive to be sprayed evenly onto the surface of the drainage board 21 in an atomized form.

[0042] The pressure regulating valve 520 controls the air pressure of the spray gun 510. It precisely adjusts the pressure of the compressed air entering the spray gun 510 according to production process requirements. Different specifications, surface structures, and bonding requirements of the drainage boards 21 necessitate different adhesive thicknesses and effects. By adjusting the pressure regulating valve 520, the spraying force and atomization degree of the spray gun 510 can be changed, thereby achieving precise control of the adhesive thickness. During production, various factors, such as changes in the viscosity of the hot melt adhesive and fluctuations in ambient temperature, may lead to unstable adhesive effects. The pressure regulating valve 520 can adjust the air pressure of the spray gun 510 in a timely manner according to actual conditions to compensate for these factors, ensuring that the adhesive thickness remains within the set range and improving the stability and consistency of product quality. When producing different models or specifications of self-adhesive three-dimensional protective drainage board composite rolls for side walls, different adhesive thickness settings may be required. The adjustment function of the pressure regulating valve 520 allows the production equipment to flexibly adapt to these changes without requiring large-scale adjustments or replacements of the spray gun 510 or other components, improving the versatility and flexibility of the production equipment.

[0043] Reference Figure 1 and Figure 2According to the production equipment 10 of the self-adhesive three-dimensional protective drainage board composite roll material provided by this utility model, the glue spraying module 500 also includes an online glue layer thickness gauge 530. The online glue layer thickness gauge 530 is located behind the spray gun 510 along the production direction. The online glue layer thickness gauge 530 is connected to the pressure regulating valve 520. The online glue layer thickness gauge 530 is used to monitor the glue spraying thickness through the spray gun 510 in real time, and adjust the air pressure value of the spray gun 510 through the pressure regulating valve 520 according to the difference between the glue spraying thickness and the preset glue layer thickness.

[0044] Understandably, the online adhesive layer thickness gauge 530 can monitor the thickness of the hot melt adhesive layer sprayed from the spray gun 510 in real time, ensuring the uniformity and consistency of the adhesive spraying.

[0045] The online adhesive thickness gauge 530, connected to the pressure regulating valve 520, automatically adjusts the air pressure of the spray gun 510 based on the difference between the monitored adhesive thickness and the preset adhesive thickness. This ensures that the adhesive thickness remains within the preset range, reducing human error and improving production efficiency and product quality.

[0046] Reference Figure 2 According to the production equipment 10 of the self-adhesive three-dimensional protective drainage board composite roll provided by this utility model, the online adhesive layer thickness gauge 530 is movably installed above the drainage board 21 production line through the guide rail slider moving assembly 540. The guide rail slider moving assembly 540 can drive the online adhesive layer thickness gauge 530 to make reciprocating linear motion along the width direction of the drainage board 21.

[0047] It is understandable that the drainage board 21 has a certain width. During the production process, the hot melt adhesive may not be applied evenly to the surface of the drainage board 21, and the adhesive layer thickness may vary at different locations. The guide rail slider moving assembly 540 drives the online adhesive layer thickness gauge 530 to reciprocate linearly along the width direction of the drainage board 21, enabling the thickness gauge to detect the adhesive layer thickness across the entire width of the drainage board 21, rather than being limited to a single fixed position. This allows for a comprehensive and accurate understanding of the adhesive layer thickness distribution across the entire surface of the drainage board 21, avoiding the omission of problems in other areas due to localized inspection, and thus promptly detecting defects such as uneven adhesive layer thickness.

[0048] Meanwhile, the production equipment may need to produce self-adhesive three-dimensional protective drainage board composite rolls with different widths. The guide rail slider moving assembly 540 allows the online adhesive layer thickness gauge 530 to adjust its detection range according to the actual width of the drainage board 21. When producing products with different widths, it is only necessary to control the guide rail slider moving assembly 540 to make the thickness gauge perform detection within the corresponding width range, without the need for complex reinstallation or adjustment of the detection equipment. This improves the versatility and flexibility of the equipment and can quickly adapt to the production needs of different products.

[0049] Optionally, the spray width of the spray gun 510 is 30mm to 50mm.

[0050] Understandably, by setting the spraying width of the spray gun 510 within the range of 30mm to 50mm, it can be ensured that the spray gun 510 can effectively cover the surface of the drainage board 21, especially when the surface of the drainage board 21 is uneven, so that the hot melt adhesive can be sprayed evenly and the situation of missed spraying or uneven adhesive spraying can be avoided.

[0051] Optionally, the spraying width of the spray gun 510 can be set to a suitable spraying range according to the width and length of the drainage board 21 and the number of spray guns 510. For example, if the width of the drainage board 21 is 3m and the number of spray guns 510 is ten, then the spraying range of the spray gun 510 can be selected as 30mm.

[0052] Reference Figure 1 According to the present invention, a production equipment 10 for a sidewall self-adhesive three-dimensional protective drainage board composite roll material is provided. The material extrusion module 100 includes a single screw extruder 110 and a T-die 120. The single screw extruder 110 is used to plasticize the raw material and then output it to the T-die 120 through a metering pump pressure, and the T-die 120 extrudes molten sheet material.

[0053] Understandably, the single-screw extruder 110 can plasticize the input raw materials. In the production of the self-adhesive three-dimensional protective drainage board 21 composite roll material, the raw materials are typically solid granules or powder. The single-screw extruder 110, through heating and shearing, melts the raw materials, making them plastic. After plasticization, the raw materials are pumped at a certain pressure into the T-die 120 through a metering pump inside the single-screw extruder 110. The metering pump can precisely control the output of the material, ensuring a stable and uniform flow rate of material entering the T-die 120, thereby guaranteeing the production of consistently high-quality sheets.

[0054] Reference Figure 1 According to the production equipment 10 of the self-adhesive three-dimensional protective drainage board composite roll material provided by the present invention, the extrusion molding module 200 includes a two-roll forming machine and a vacuum siphon system. The two-roll forming machine includes a convex film roller and a concave film roller that cooperate with each other. After the sheet material extruded by the material extrusion module 100 is squeezed by the convex film roller and the concave film roller, it is adsorbed and formed into a drainage board 21 with multiple protrusions by the vacuum siphon system.

[0055] It is understood that this embodiment, through the combination of a two-roll forming machine and a vacuum siphon system, can accurately form a drainage plate 21 with multiple bosses. The convex and concave film rollers of the two-roll forming machine cooperate with each other to ensure the accurate forming and stability of the boss structure; the vacuum siphon system reduces wrinkles and air bubbles during the forming process through adsorption, improves the forming quality, and ensures that the shape and size of each boss are consistent.

[0056] Reference Figure 1 According to the production equipment 10 of the self-adhesive three-dimensional protective drainage board composite roll material provided by this utility model, the adhesive coating and covering module 300 includes a hot melt adhesive roller coating machine 310 and a geotextile covering roller group 320. The hot melt adhesive roller coating machine 310 rolls an uncured hot melt adhesive onto the upper surface of the protrusion of the drainage board 21 after molding and cooling. The geotextile covering roller group 320 is used to cover the geotextile 23 with the drainage board 21 coated with uncured hot melt adhesive.

[0057] Understandably, the hot melt adhesive roller coating machine 310 applies a layer of uncured hot melt adhesive to the upper surface of the protrusion of the drainage board 21 after it has been formed and cooled. The hot melt adhesive can be remelted by heating or other means during subsequent use, thereby firmly adhering the drainage board 21 to the base surface such as the side wall, realizing convenient installation and reliable fixation of the drainage board 21, and meeting its use requirements as a side wall protection and drainage material.

[0058] The geotextile covering roller assembly 320 covers the geotextile 23 with the drainage board 21 coated with uncured hot melt adhesive, so that the drainage board 21 and the geotextile 23 are combined into one, forming a composite roll material.

[0059] Reference Figure 1 According to the present invention, a production equipment 10 for a self-adhesive three-dimensional protective drainage board composite roll material for side walls includes a film coating module 600 comprising a film coating roller group 610, which is used to coat the film 25 onto the side of the drainage board 21 covered with geotextile 23 and sprayed with hot melt adhesive.

[0060] It is understood that in this embodiment, a layer of uncured hot melt adhesive is applied to the upper surface of the protrusion of the drainage board 21 by a hot melt adhesive roller coater 310, providing a strong bonding layer for the overlay of the geotextile 23. The geotextile overlay roller group 320 then overlays the geotextile 23 with the hot melt adhesive layer to form a composite structure, ensuring a strong bond between the geotextile 23 and the drainage board 21, and improving the overall quality and performance of the composite roll material.

[0061] Reference Figure 1According to the present invention, a production equipment 10 for a sidewall self-adhesive three-dimensional protective drainage board composite roll material is provided. The traction and winding module 700 includes a traction machine 710 and a winding machine 720. The traction machine 710 is located between the film coating module 600 and the winding machine 720. The traction machine 710 is used to pull the drainage board 21 after film coating in the film coating module 600 to the winding machine 720. The winding machine 720 is used to wind the drainage board 21 to form a finished roll.

[0062] Understandably, the traction machine 710 ensures that the drainage board 21 moves continuously and smoothly on the production line by providing stable traction force, avoiding pauses and interruptions in the production process, while precisely controlling the tension to ensure that the drainage board 21 is in a stable state after coating.

[0063] The winding machine 720 then winds the coated drainage board 21 into a finished roll, completing the final product formation and ensuring the flatness and tightness of the finished roll for easy subsequent packaging and transportation.

[0064] In some embodiments, a cutting mechanism is provided between the traction machine 710 and the winding machine 720. The cutting mechanism cuts the traction machine 710 to a set length. The cut drainage board 21 enters the winding machine 720 to finally form a finished roll.
