Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to a composite polymer waterproof membrane production line. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile has excellent filtration, isolation, reinforcement and protection functions, high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance, and corrosion resistance, and can play a very good role in filtration, isolation, reinforcement and protection.

[0003] In the production process of composite polymer waterproof membrane production line, the roll forming process is a key step in achieving the bonding of the substrate and the geotextile. However, in actual production, due to factors such as complex raw material storage environment and lax control in transportation, metallic impurities such as iron filings, screws, and iron sheets are easily mixed into the surface of the geotextile.

[0004] When geotextile carrying metal objects enters the roller pressing station, the metal foreign objects hidden between the fabric fiber layers will enter the roller gap simultaneously with the substrate, causing serious damage to the roller pressing mechanism. At best, this will result in scratches and dents on the surface of the roller pressing mechanism, affecting the quality of the geotextile and production efficiency; at worst, it may damage key components of the roller pressing mechanism, or even cause equipment failure, production interruption, and huge economic losses to the company.

[0026] The following is combined Figure 1 Figure 2The present invention will be described in detail through specific embodiments and application scenarios of a composite polymer waterproof membrane production line provided by the present invention.

[0027] In the embodiments of the utility model, such as Figure 1 As shown, a composite polymer waterproof membrane production line 10 includes an unwinding platform 100, a roller pressing mechanism 200, a guiding mechanism 300, and an iron removal device 400. The unwinding platform 100 is provided with an unwinding roller 110, which is used to unwind and collect the geotextile 20 rolls. The roller pressing mechanism 200 is disposed on one side of the unwinding platform 100 and is used to perform roller pressing composite treatment on the geotextile 20 body after it has been unwound by the unwinding platform 100. The guiding mechanism 300 includes at least one guide roller, which is disposed between the unwinding roller 110 and the roller pressing mechanism 200. The guide roller is used to guide the geotextile 20 unwound by the unwinding roller 110 toward the roller pressing mechanism 200. The iron removal device 400 includes at least two sets of magnetic rod structures 410, which abut against both sides of the geotextile 20 along its thickness direction, and the magnetic rod structures 410 extend along the width direction of the geotextile 20.

[0028] As the initial load-bearing component of the entire production line, the unwinding platform 100 provides a stable foundation for the installation and operation of the unwinding roller 110, ensuring that the unwinding process can proceed smoothly and orderly.

[0029] The unwinding roller 110 unfolds the geotextile roll 20, enabling the geotextile roll 20 to be continuously and evenly output according to production needs, providing a stable supply of fabric for subsequent processing steps such as rolling. When production is completed or when the geotextile roll 20 needs to be replaced, the remaining geotextile roll 20 can be stored away for easy management, and also helps to protect the geotextile roll 20 from contamination or damage.

[0030] The roller pressing mechanism 200 is located on one side of the unwinding platform 100 to perform roller pressing composite treatment on the geotextile 20 and the substrate after it has been unwound by the unwinding platform 100.

[0031] Optionally, the roller pressing mechanism 200 of this application can be configured as needed. This application takes the roller pressing mechanism 200 as a three-roller mechanism as an example for illustration. The three-roller mechanism is arranged in the vertical direction, and the geotextile 20 is rolled from bottom to top.

[0032] The guide roller is positioned between the unwinding roller 110 and the roller pressing mechanism 200, accurately guiding the geotextile 20 unwound from the unwinding roller 110 to the roller pressing mechanism 200. This ensures that the geotextile 20 does not deviate or wrinkle during the conveying process, guaranteeing that the fabric can smoothly and steadily enter the roller pressing mechanism 200 for processing, thereby improving the stability of the production process and the consistency of product quality.

[0033] Optionally, the number of guide rollers can be set as needed, and no special limitation is made here.

[0034] To a certain extent, the guide rollers can also adjust the tension of the geotextile 20. By reasonably setting the position and angle of the guide rollers, the tightness of the fabric during the conveying process can be controlled, avoiding excessive tension causing the fabric to stretch and deform or insufficient tension causing the fabric to loosen and wrinkle, which would affect the subsequent rolling effect.

[0035] The iron removal device 400 includes at least two sets of magnetic rod structures 410, which abut against both sides of the geotextile 20 along its thickness direction, and extend along the width direction of the geotextile 20. This design allows the magnetic rod structures 410 to fully cover the entire width and thickness range of the geotextile 20, strongly adsorbing iron filings, nails, and other iron impurities that may be present on the surface and inside the geotextile 20. Before the geotextile 20 enters the roller pressing mechanism 200, iron impurities are effectively removed, preventing iron from entering the roller pressing mechanism 200.

[0036] Since iron objects are extremely damaging to the roller pressing mechanism 200, they may scratch the surface of the roller pressing rollers, damage the key components of the roller pressing mechanism 200, or even cause equipment failure. The iron removal device 400 removes iron objects, thus avoiding damage to the roller pressing equipment, extending the service life of the equipment, reducing the cost of equipment maintenance and replacement, and ensuring the continuity and stability of the production process.

[0037] The presence of iron can affect the quality of geotextiles, such as causing surface defects and impacting their mechanical properties. The iron removal device 400 eliminates iron impurities, helping to improve the quality of the geotextile, making it more suitable for engineering applications, and enhancing the product's market competitiveness.

[0038] Optionally, the number of magnetic rod structures 410 can be set as needed, and no special limitation is made here.

[0039] This application provides magnetic rod structures 410 on both sides of the geotextile 20 to fully cover the entire surface of the geotextile 20 and to abut against the surface of the geotextile 20. When the geotextile 20 passes through the magnetic rods, the magnetic rods can attract iron objects from the surface of the fabric, effectively preventing iron objects from entering the rolling mechanism 200, avoiding damage to the rolling mechanism 200, ensuring the rolling quality, and thus improving production quality.

[0040] In one embodiment, the magnetic rod structure 410 includes a magnetic rod, a lead rod, and two mounting brackets. The two mounting brackets are respectively disposed at both ends of the geotextile 20 along the width direction. The lead rod passes through the magnetic rod, and both ends of the lead rod are respectively connected to the mounting brackets.

[0041] Understandably, the magnetic rod, through its own magnetism, can attract iron filings, nails, and other iron impurities hidden on and inside the geotextile 20. When the geotextile 20 passes over the magnetic rod, the iron objects are attracted by the magnetic field of the rod and adhere to its surface, thus effectively preventing the iron objects from entering the subsequent rolling mechanism 200, avoiding damage to the equipment, and ensuring the production quality of the geotextile.

[0042] Optionally, the magnetic strength, size, and other parameters of the magnetic rod can be customized according to actual production needs.

[0043] A lead screw is inserted into the magnetic rod, with its two ends connected to two mounting brackets respectively, serving to support the magnetic rod and stably fix it between the mounting brackets. At the same time, the lead screw acts as a connecting component, organically combining the magnetic rod and the mounting brackets to form a complete magnetic rod structure 410, ensuring the stability and reliability of the entire structure.

[0044] Two mounting brackets are positioned at both ends of the geotextile 20 along its width, providing a fixed base for the entire magnetic rod structure 410. These brackets securely install the magnetic rod structure 410 in the appropriate location on the composite polymer waterproof membrane production line 10, ensuring that the magnetic rods are accurately positioned above or below the geotextile 20 for effective iron removal. Furthermore, the mounting brackets can be designed and adjusted according to the production line layout and installation requirements to ensure coordinated operation of the magnetic rod structure 410 with other production equipment.

[0045] In one embodiment, the magnetic rod is rotatably connected to the lead screw, and the magnetic rod is rolled against the outer surface of the geotextile 20.

[0046] Understandably, the magnetic rod is rotatably connected to the lead screw, allowing it to rotate freely during operation. This reduces sliding friction between the magnetic rod and the geotextile 20, replacing it with rolling friction, thereby lowering the frictional force and reducing wear on the geotextile 20.

[0047] The magnetic rod rolls against the outer surface of the geotextile 20, allowing it to dynamically attract iron objects as the geotextile 20 moves. This dynamic contact is more effective than static contact because the rotation of the magnetic rod can better adapt to the moving speed and direction of the geotextile 20. The rolling contact reduces direct sliding contact between the magnetic rod and the geotextile 20, thereby reducing scratches and damage that could result from sliding contact and further protecting the surface quality of the geotextile 20.

[0048] In one embodiment, when the geotextile 20 moves along the unwinding platform 100 toward the rolling mechanism 200, the magnetic rod rotates around its own axis, and the linear velocity direction of the contact area between the outer surface of the magnetic rod and the surface of the geotextile 20 is consistent with the rolling direction of the geotextile 20.

[0049] Understandably, the linear velocity direction of the contact area between the outer surface of the magnetic rod and the surface of the geotextile 20 is consistent with the flow direction of the geotextile 20, resulting in a relatively stable dynamic contact between the magnetic rod and the geotextile 20. This dynamic contact method allows the magnetic rod to continuously and uniformly "scan" the surface and interior of the geotextile 20, which can more effectively capture and adsorb iron impurities compared to static contact or contact with inconsistent linear velocity directions.

[0050] Meanwhile, when the linear velocity direction of the contact area between the outer surface of the magnetic rod and the surface of the geotextile 20 is consistent with the flow direction of the geotextile 20, the relative motion between the two is a smooth rolling or near-rolling state, rather than sliding friction. This motion mode greatly reduces the friction between the magnetic rod and the geotextile 20, reduces the wear on the fabric surface, and ensures the integrity and quality of the geotextile 20.

[0051] Reference Figure 2 In one embodiment, the iron removal device 400 further includes an iron scraping mechanism 420, which is installed beside the rotation path of the magnetic rod and has a mating gap with the surface of the magnetic rod.

[0052] Understandably, by setting up the iron scraping mechanism 420, iron objects adsorbed on the surface of the magnetic rod can be scraped off in a timely manner, preventing excessive accumulation of iron objects on the surface of the magnetic rod and affecting the adsorption effect of the magnetic rod. At the same time, it can also prevent iron objects adsorbed on the magnetic rod from scratching the surface of the geotextile 20.

[0053] The iron scraping mechanism 420 is positioned next to the rotation path of the magnetic rod, so that when the magnetic rod rotates past this position, the iron scraping mechanism 420 can easily scrape off the iron adsorbed on the magnetic rod. The rotation of the magnetic rod is used to separate the iron from the magnetic rod, ensuring that the scraping action can be carried out in a timely and effective manner. In conjunction with the rotation action of the magnetic rod, a complete iron removal and iron cleaning process is formed.

[0054] There is a fitting gap between the iron scraping mechanism 420 and the surface of the magnetic rod. A suitable fitting gap can ensure that the iron scraping mechanism 420 can smoothly scrape off the iron adsorbed on the magnetic rod, and will not cause friction or collision between the iron scraping mechanism 420 and the magnetic rod during rotation due to the gap being too small, which would affect the normal operation and service life of the equipment. At the same time, the gap will not be too large, which would prevent the iron from being scraped off effectively. This ensures that the iron scraping mechanism 420 can play a stable and reliable role, and improves the stability and reliability of the entire iron removal device 400.

[0055] Reference Figure 2In one embodiment, the iron scraping mechanism 420 includes a scraper and a mounting bracket for fixing the scraper. The mounting bracket is connected to the mounting bracket. The scraper extends along the length of the magnetic rod, and the scraping edge of the scraper faces the outer circular surface of the magnetic rod. The extension direction of the scraping edge is parallel to the rotational tangent direction of the outer circular surface of the magnetic rod, so that when the magnetic rod rotates around its own axis, the scraper can scrape off the iron adsorbed on it along the tangent direction of the outer circular surface of the magnetic rod.

[0056] Understandably, the scraper is the component that directly performs the scraping action on the iron, while the mounting bracket serves to fix the scraper, providing a stable support structure for the scraper, ensuring that the scraper is fixed in position during operation, and can accurately and effectively perform the scraping task.

[0057] The scraping edge of the scraper extends in a direction parallel to the rotational tangent of the outer surface of the magnetic rod, allowing the scraper to scrape along the rotational direction of the magnetic rod, reducing wear on the surface of the magnetic rod during the scraping process, and improving the scraping efficiency of ironware.

[0058] In one embodiment, the gap between the scraping blade and the outer surface of the magnetic rod is 0.1mm to 0.3mm.

[0059] Understandably, when the gap is within the range of 0.1mm to 0.3mm, the scraping blade can closely adhere to the outer surface of the magnetic rod. The iron objects attracted by the magnetic rod may contain thin layers of iron filings, iron powder, or other impurities. An excessively large gap would prevent these thin layers of iron from being effectively scraped away by the scraper, leaving them still attached to the magnetic rod. This gap range ensures that the scraping blade generates sufficient scraping force to thoroughly remove these thin layers of iron from the surface of the magnetic rod, improving the thoroughness of iron removal.

[0060] Reference Figure 2 In one embodiment, the iron removal device 400 further includes an iron collection mechanism 430, which is disposed below the scraper and within the rotation trajectory coverage of the magnetic rod. The iron collection mechanism 430 is used to receive iron scraped off by the scraper along the tangential direction.

[0061] Understandably, the iron collection mechanism 430 is positioned below the scraper and within the rotation trajectory of the magnetic rod, enabling it to precisely collect iron scraped off tangentially by the scraper. During the iron removal process, after the scraper removes the iron adsorbed on the magnetic rod, the iron falls naturally under gravity. The iron collection mechanism 430 provides a fixed collection point, preventing the scraped iron from scattering and ensuring the integrity and continuity of the iron removal process, thus improving efficiency. Simultaneously, the iron collection mechanism 430 ensures that the iron is collected immediately after being scraped off, reducing the possibility of it being re-adsorbed by the magnetic rod and enhancing the thoroughness of the iron removal effect.

[0062] In one embodiment, the ironware collection mechanism 430 includes a collection trough and a collection box, the opening of the collection trough facing the scraping edge of the scraper, and the collection box being detachably disposed at the bottom of the collection trough.

[0063] Understandably, the opening of the collection trough faces the scraping edge of the scraper to ensure that the iron scraped by the scraper can fall directly into the collection trough, preventing the iron from scattering due to gravity or inertia after scraping.

[0064] The removable collection box design makes cleaning and maintenance easier. Operators can easily remove the collection box for cleaning or replacement, reducing maintenance time and costs.

[0065] Optionally, the magnetic rod is a 12000 Gauss magnetic rod or an electromagnet.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
