Description

Technical Field

[0001] This invention relates to the field of waterproof material production technology, and in particular to an automated extrusion composite molding device for waterproof rolls. Background Technology

[0002] Waterproof membrane is a flexible building material widely used in building roofs, basements, tunnels, and other projects. It is usually composed of multiple layers of materials, including a base layer, a coating layer, and a release liner. Traditional composite molding processes often use a step-by-step method, that is, first coating the base layer with asphalt or polymer adhesive, and then attaching the release liner (such as PE film or silicone film) or reinforcing layer (such as non-woven fabric) through a separate composite station.

[0003] In existing extrusion compounding equipment, the coating and hot-pressing processes are typically carried out in an open or semi-open environment. When molten adhesive is extruded onto the substrate through the die, some adhesive may overflow from the substrate edges or drip through the substrate onto the equipment base and conveyor components below due to factors such as substrate permeability, surface unevenness, or equipment vibration. This residual adhesive gradually accumulates and solidifies, not only wasting raw materials but also contaminating the equipment's working surface, affecting the smooth transport of the substrate, and in severe cases, even requiring shutdown for cleaning, reducing production efficiency and increasing maintenance costs. Furthermore, traditional cooling methods are often not uniform enough, which may affect the final forming quality of the roll material.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-4 This invention provides an automated extrusion and composite molding device for waterproof membranes, comprising:

[0031] Workbench 1, from left to right, is provided with substrate unwinding roller 2, coating hot pressing assembly, cooling assembly and winding roller 3;

[0032] The coating hot pressing assembly includes an insulation box 4, a coating component, and a hot pressing component. The substrate on the substrate unwinding roller 2 is conveyed into the insulation box 4. The coating component is used to coat the substrate with adhesive, and the hot pressing component is used to hot press the substrate after coating with adhesive to form a composite material.

[0033] The cooling assembly includes a cooling box 5 and a cooling component. The cooling box 5 is connected to the insulation box 4. The laminated substrate is transported into the cooling box 5 and cooled by the cooling component.

[0034] The recycling component is located inside the insulation box 4 and below the coated component. The recycling component is used to recycle the adhesive material extruded from the substrate.

[0035] In one embodiment of the present invention, the substrate on the substrate unwinding roller 2 passes through the insulation box 4 and is conveyed to the cooling assembly and the take-up roller 3. The coating component is used to pump molten adhesive onto the substrate, and then the composite material is hot-pressed by the hot pressing component. After hot pressing, the waterproof material is cooled by the cooling component to prepare the waterproof material. The prepared waterproof material is then wound onto the take-up roller 3. At the same time, during the coating process, the adhesive is recycled by the set recycling component to ensure the cleanliness of the coating component and ensure the stable coating of the subsequent substrate.

[0036] As an optional implementation, the coating includes a base 6, a substrate is laid on the top of the base 6, an extruder 7 is fixedly connected to the top of the inside of the insulation box 4, the extruder 7 is connected to the external material box, an extrusion die 8 is fixedly connected to the bottom of the extruder 7, the extrusion die 8 is located above the base 6, and an extrusion roller 10 is installed inside the insulation box 4 through a first hydraulic cylinder 9, the extrusion roller 10 is used to extrude the rubber material.

[0037] In one embodiment of the present invention, the base 6 provides a flat and stable coating working surface for the substrate. Combined with the upper extrusion die 8 for precise material distribution and the lower extrusion roller 10 for controllable pressure, it ensures that the adhesive can be uniformly coated and fully penetrate into the substrate, effectively controlling the thickness and quality of the coating layer.

[0038] As an optional implementation, the hot press includes a composite material unwinding roller 11, which is installed on the inner wall of the heat preservation box 4.

The heating composite roller 13 is used to press the composite material.

[0039] In one embodiment of the present invention, the unwinding roller 11 of the composite material is integrated inside the heat preservation box 4, so that the composite material is hot-pressed and laminated immediately while the rubber is still in the best melting state. The heating roller 13 provides uniform pressure and temperature under hydraulic drive, so that the composite material and the rubber layer achieve a strong molecular-level bond, effectively avoiding defects such as bubbles and delamination.

[0040] As an optional implementation, the cooling component includes two cold air ducts 14, which are fixedly connected to the top and bottom of the cooling box 5 respectively. One end of the cold air duct 14 is fixedly connected to an air outlet 15, and a cold air fan 16 is fixedly connected to the top of the cooling box 5. The other end of the cold air duct 14 is connected to the output end of the cold air fan 16.

[0041] In one embodiment of the present invention, the upper and lower surfaces of the composite roll can be uniformly and efficiently cooled by forced air at the same time, avoiding the problems of uneven stress, deformation or warping of the roll caused by single-sided cooling, and ensuring the stability of product dimensions and the uniformity of physical properties.

[0042] As an optional implementation, a bracket 17 is fixedly connected inside the cooling box 5, and a number of guide rollers 18 are mounted on the bracket 17 along the axial direction.

[0043] In one embodiment of the present invention, multiple guide rollers 18 are provided in the cooling box, which allows the composite roll to pass through in a meandering, serpentine path, significantly extending the residence time and cooling path of the roll in the cooling box without increasing the length of the equipment.

[0044] As an optional implementation, the recyclable component includes a fixed frame 19, which is fixedly connected to the bottom of the insulated box 4. Two rotating rollers 20 are installed on both sides of the fixed frame 19. Protective belts 21 are sleeved on the two rotating rollers 20 on the same side. The protective belts 21 are in the form of a ring structure. The upper layer of the ring structure is located at the top of the base 6, and the lower layer of the ring structure is located below the base 6. The substrate is laid between the two protective belts 21.

[0045] In one embodiment of the present invention, by setting an annular protective belt 21 under the substrate, all excess adhesive that overflows from the edge of the substrate or seeps downwards is received, and the easily contaminated base is transformed into a recyclable and self-cleaning protective belt 21, thereby achieving active protection in the production process and ensuring the cleanliness of the substrate transmission path.

[0046] As an optional implementation, a collection trough 22 is fixedly connected to the mounting bracket 19. The collection trough 22 is located below the two protective belts 21. Two scrapers 23 are fixedly connected inside the collection trough 22, and the scrapers 23 are in contact with the protective belts 21.

[0047] In one embodiment of the present invention, the scraper 23 can promptly and automatically scrape off the residual adhesive material adhering to the rotating protective belt 21 and make it fall into the collection tank 22 for centralized storage, thereby realizing the automated collection of waste materials, facilitating subsequent cleaning and recycling, keeping the surface of the protective belt 21 clean, and ensuring its continuous and effective operation.

[0048] As an optional implementation, a fixing plate 24 is fixedly connected to both sides of the fixing frame 19. A slide rod 25 is slidably connected to the fixing plate 24. A limit plate 26 is fixedly connected to the top of the slide rod 25. A spring 27 is sleeved on the slide rod 25. The two ends of the spring 27 are fixedly connected to the limit plate 26 and the fixing plate 24 respectively. A mounting frame 28 is fixedly connected to the bottom of the slide rod 25. A tension roller 29 is installed in the mounting frame 28. The tension roller 29 is located inside the annular structure and is in contact with the inner side wall of the lower layer of the annular structure.

[0049] In one embodiment of the present invention, the tensioning roller 29 is driven by the continuous elastic force provided by the spring 27 to always apply downward pressure to the inner side of the protective belt 21, thereby realizing the automatic tensioning of the protective belt 21. This can automatically compensate for the slack caused by long-term use of the protective belt 21, ensuring that the protective belt 21 always maintains appropriate tension, runs smoothly and fits tightly with the scraper 23, thus ensuring the reliability and stability of the scraping effect.

[0050] As an optional implementation, an electric heating wire is provided inside the heating and bonding roller 13.

[0051] In one embodiment of the present invention, an electric heating wire is provided inside the heating and laminating roller 13, which has the advantages of rapid heating, precise temperature control and high thermal efficiency.

[0052] As an optional implementation, guide rollers 30 are installed at both the input end of the heat preservation box 4 and the output end of the cooling box 5.

[0053] In one embodiment of the present invention, guide rollers 30 are provided at the inlet of the insulation box 4 and the outlet of the cooling box 5 to smoothly guide the substrate and composite roll into and out of the box.

[0054] This invention provides an automated extrusion composite molding device for waterproof roll materials. In use, the substrate is released from the substrate unwinding roller 2, enters the insulation box 4 via the guide roller 30, and is laid on two protective belts 21. The extruder 7 evenly coats the substrate surface with molten adhesive through the extrusion die 8, and the extrusion roller 10 presses down to allow the adhesive to penetrate and achieve a fixed thickness. During this process, excess adhesive is collected by the protective belts 21. Subsequently, the laminating material is released from the laminating material unwinding roller 11, covering the adhesive, and the heated laminating roller 13 completes the lamination under heating and pressure. The laminated roll material enters the cooling box 5 via the guide roller 30, moves forward in a meandering manner under the guidance of the guide roller 18, and is evenly cooled and shaped by the cold air blown out by the cold air pipe 14. Simultaneously, the protective belts 21, which have collected excess adhesive, continue to rotate. When they pass the scraper 23 on the collection tank 22, the surface adhesive is scraped off into the collection tank 22, and the clean protective belts 21 are reused. Finally, the cooled and shaped finished roll is wound up and collected by take-up roller 3.
