Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and more specifically, to an embossing device for waterproof membrane production. Background Technology

[0002] As a core material in building waterproofing projects, the surface embossing process of waterproof membrane directly affects its anti-slip properties, adhesion, and appearance quality. For example, the raised and recessed patterns (such as diamonds and stripes) formed by embossing can increase the contact area between the bottom surface of the membrane and the building substrate. At the same time, the patterns can be embedded in the tiny gaps on the substrate surface, making it easier for the adhesive to fill them and preventing the membrane from becoming hollow or curled due to poor adhesion, thereby preventing rainwater from seeping in through the gaps.

[0003] Embossing of waterproof membrane generally involves three steps: first, heating and softening the waterproof membrane; second, embossing; and finally, cooling and shaping. These three steps complete the embossing of the waterproof membrane. In the cooling step, the most common method for cooling waterproof membrane is to use cooling rollers. By supplying low-temperature water into the cooling rollers, the high temperature of the waterproof membrane can be carried away by the temperature difference when the waterproof membrane passes through the cooling rollers.

[0004] However, supplying water into the cooling roller will cause scale to adhere to the inner wall of the cooling roller over time. Once the scale reaches a certain thickness, it will reduce the cooling effect on the waterproof membrane. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an embossing device for producing waterproof membranes that overcomes or at least partially solves the above technical problems.

[0006] This utility model is implemented as follows: This utility model provides an embossing device for producing waterproof membrane, including a base plate, a heating roller is stably installed on the upper surface of the base plate, and a positioning frame is fixedly installed on the upper surface of the base plate. A cooling roller is rotatably installed on the inner side of the positioning frame, and a scraping mechanism is provided inside the cooling roller for scraping off scale from the inner wall of the cooling roller.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0019] Reference Figures 1-4 This utility model provides a technical solution: an embossing device for producing waterproof membrane rolls, including a base plate 1, with a heating roller 2 stably installed on the upper surface of the base plate 1, and a positioning frame 3 fixedly installed on the upper surface of the base plate 1. A cooling roller 4 is rotatably installed on the inner side of the positioning frame 3, and a scraping mechanism 5 is provided inside the cooling roller 4 for scraping off scale from the inner wall of the cooling roller 4. The base plate 1 is made of Q235 low carbon steel plate, which has good rigidity and weldability, and can withstand the weight of the heating roller 2, the positioning frame 3 and the pressure during the production process, avoiding deformation after long-term use. At the same time, after sandblasting and rust removal treatment on the upper surface of the base plate 1, a 2-5mm thick epoxy resin anti-corrosion coating is sprayed on it to prevent water vapor and residual membrane materials in the production environment from corroding the base plate 1 and extending its service life.

[0020] Three sets of electric heating tubes are evenly arranged inside the heating roller 2 along the axial direction. The heating tubes are made of Incoloy 800, and magnesium oxide powder is filled between the heating tubes and the roller body as an insulating and heat-conducting material to ensure heating efficiency while ensuring electrical safety.

[0021] The cooling roller 4 is made of 316L stainless steel.

[0022] In a preferred embodiment, the scraping mechanism 5 includes a hollow tie rod 51 and a scraping plate 52. The interior of the cooling roller 4 is hollow, and the scraping plate 52 is disposed inside the cooling roller 4. The outer side of the scraping plate 52 is in contact with the inner wall of the cooling roller 4. The hollow tie rod 51 is made of 304 stainless steel seamless tube. This material not only has excellent corrosion resistance and can resist the erosion of cooling water and scale inside the cooling roller 4, but also reduces its own weight while ensuring structural strength. At the same time, the inner hole of the hollow tie rod 51 can be used to pass water pipes.

[0023] The scraper 52 adopts a polyurethane scraping layer structure, which balances scraping effect and structural stability. Its surface is treated with micro-convex texture, which can enhance the adhesion of scale and improve scraping efficiency, while avoiding scale residue due to excessive smoothness.

[0024] In a preferred embodiment, a hollow hole 6 is provided at the center of the outer side of the scraping plate 52, and the hollow hole 6 is connected to the interior of the hollow pull rod 51. A plurality of drainage holes 7 are provided on the outer surface of the hollow pull rod 51. The edge of the hollow hole 6 at the center of the outer side of the scraping plate 52 is arc-shaped, and the inner wall is polished to prevent scale from accumulating in the hole. The diameter of the hollow hole 6 is smaller than the diameter of the hollow pull rod 51.

[0025] The drain hole 7 on the outer surface of the hollow tie rod 51 adopts a circular through hole structure. The drain hole 7 is regularly distributed along the axial and circumferential directions of the hollow tie rod 51. The drain hole 7 can allow liquid to enter the interior of the cooling roller 4 from the drain hole 7, thereby cooling the waterproof membrane by cooling the cooling roller 4.

[0026] In a preferred embodiment, one end of the cooling roller 4 is internally connected to an inlet pipe 8 that extends into the hollow hole 6, and the other end of the cooling roller 4 is internally connected to a drain pipe 9 that is disposed inside the hollow pull rod 51 and extends out from the inside of any drain hole 7. The inlet pipe 8 is made of food-grade 304 stainless steel, which has excellent corrosion resistance and can resist the erosion of impurities in the cooling water, preventing scale from adhering inside the pipe. In use, one end of the inlet pipe 8 is inserted into the hollow hole 6. When water is supplied into the inlet pipe 8, the water can directly enter the hollow pull rod 51 and be released from the drain hole 7 into the cooling roller 4. A control valve is also provided at the outer end of the inlet pipe 8, i.e., at the outside of the cooling roller 4. The outer end of the inlet pipe 8 is connected to a first water pump, which draws water and delivers it into the cooling roller 4.

[0027] One end of the drain pipe 9 extends into a drain hole 7 and extends out. When the liquid level inside the cooling roller 4 reaches a certain level, the water inside the cooling roller 4 will be extracted by a second water pump connected to the outside of the drain pipe 9 and transported to the outside water collection tank, thereby realizing the recycling of water.

[0028] The outer surface of the cooling roller 4 is provided with a slag discharge hole 10 with a diameter of 8cm-12cm. A sealing plug is inserted inside the slag discharge hole 10. There are two slag discharge holes 10, which are respectively set at symmetrical positions at both ends of the cooling roller 4. Each slag discharge hole 10 is provided with a sealing plug. When there is scale, the scale can be discharged from the slag discharge hole 10 by the scraper 52 moving back and forth inside the cooling roller 4, so as to remove the scale inside the cooling roller 4 in time.

[0029] An embossing roller 11 is installed on the upper inner side of the positioning frame 3. A winding roller 12 is rotatably installed between the embossing roller 11 and the cooling roller 4. The embossing roller 11 is made of 45# quenched and tempered steel with a hardness of HRC45-50. It has excellent wear resistance and deformation resistance, can maintain the clarity of the embossed pattern for a long time, and can also reduce the overall weight of the roller body and reduce the load on the positioning frame 3.

[0030] The winding roller 12 is made of 6061 aluminum alloy, and after aging treatment, its hardness reaches HB95-105. It combines lightweight and certain rigidity, which can reduce rotational resistance and reduce energy consumption. The roller body surface is anodized to reduce frictional resistance with the waterproof membrane and avoid scratches or tensile deformation on the membrane surface.

[0031] A mounting bracket 13 is fixedly installed on the upper surface of the base plate 1, and a hydraulic cylinder 14 is stably installed on top of the mounting bracket 13. The telescopic end of the hydraulic cylinder 14 is equipped with a rotatable pressure roller 15. The mounting bracket 13 is welded from Q355 low-alloy high-strength steel, which has a yield strength increased by more than 30% compared to ordinary Q235 steel, enabling it to stably bear the working load of the hydraulic cylinder 14 and the pressure roller 15. The hydraulic cylinder 14 is a single-piston rod type, model HOB80×150-FA, which can meet the pressure requirements of waterproof membranes of different thicknesses (1-10mm) and ensure long-term stable operation.

[0032] The pressure roller 15 adopts a composite structure of "steel core + rubber outer layer". The steel core is made of No. 45 steel, and the rubber outer layer is made of nitrile rubber, which has good elasticity and wear resistance. It can fit tightly to the surface of the waterproof membrane and avoid damaging the membrane.

[0033] The upper surface of the base plate 1 is also equipped with a winding roller 16 that is controlled by a motor, and a support base 17 for supporting the base plate 1 is fixedly installed at the bottom of the base plate 1. The winding roller 16 is made of 304 stainless steel seamless tube, which ensures the rigidity of the roller body and reduces its own weight, thereby reducing the load on the drive motor. The drive motor of the winding roller 16 is a variable frequency speed control motor model YVF2-132M-4.

[0034] Specifically, the working process or working principle of an embossing device for producing waterproof membrane is as follows: This equipment will perform three steps when embossing waterproof membrane: heating, embossing, and cooling to complete the embossing operation of the waterproof membrane.

[0035] After the waterproof membrane is embossed, the equipment will transfer the waterproof membrane to the cooling roller 4. The cooling roller 4 will cool the waterproof membrane. Water at 15℃-20℃ will be circulated inside the cooling roller 4. The water temperature of 15℃-20℃ will keep the cooling roller 4 at this temperature range, which can cool the waterproof membrane.

[0036] To prevent scale buildup inside the cooling roller 4 from affecting the cooling effect on the waterproof membrane, it is necessary to clean the scale inside the cooling roller 4 regularly during use. This is done by pulling the sealing plug out of the slag discharge hole 10 and rotating the cooling roller 4 so that the slag discharge hole 10 faces downwards. Then, pull the hollow pull rod 51, which will move the scraper 52 inside the cooling roller 4. The scraper 52 can remove the scale adhering to the inner wall of the cooling roller 4 and push the scale to the slag discharge hole 10 to discharge it. By repeatedly pulling the scraper 52, the scale inside the cooling roller 4 can be cleaned.

[0037] Then, insert the sealing plug into the slag discharge hole 10 and continue to add water at 15℃-20℃ into the cooling roller 4 to continue cooling the waterproof membrane.
