Description

Technical Field

[0001] This utility model relates to the field of engineering materials technology, specifically to a geomembrane coating device. Background Technology

[0002] Geomembrane is a flexible waterproof barrier material made from high-molecular polymers. It typically appears as black or white rolls and has extremely low permeability. The core function of geomembrane is to form a reliable impermeable barrier, thus it is widely used in water conservancy projects, environmental protection projects, municipal engineering, and transportation infrastructure, playing a crucial role in seepage prevention, isolation, and protection. Geomembrane provides an effective technical solution for ensuring the safety of engineering structures and protecting water and soil resources and the ecological environment.

[0003] Although high-quality geomembranes already contain a small amount of carbon black as a UV stabilizer, in some applications requiring extremely high long-term exposure durability, or for light-colored, transparent geomembranes, additional UV-resistant varnishes or coatings are needed to further delay aging. In existing technologies, during the application of the UV-resistant coating, the base fabric is fed through guide rollers and drive rollers. However, due to accumulated errors and other factors, the tension of the base fabric changes during transmission. Excessive tension causes stretching and deformation of the base fabric, while insufficient tension causes it to loosen and wrinkle, both affecting the coating quality and uniformity, indicating room for technological improvement. Utility Model Content

[0004] This invention aims to solve the technical problem mentioned above, where the tension of the base fabric changes during the transmission process due to the accumulation of errors and other reasons, and provides a geomembrane coating device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a geomembrane coating device, including an installation frame, the installation frame including a side plate one and a side plate two symmetrically arranged, a roller is rotatably provided between the side plate one and the side plate two and a number of support rods are fixedly connected thereto;

[0006] The two side plates are provided with transverse support arms on opposite sides, and the transverse support arms are rotatably connected to the rollers. A guide roller and a tension roller are respectively rotatably provided between the two ends of the transverse support arms. A tension sensor is provided at both ends of the tension roller, and a thrust ring is provided inside the tension sensor. The tension roller and the guide roller both include a shaft core and a roller body.

[0007] Furthermore, the roller is located at the middle of several support rods.

[0008] Furthermore, both ends of the roller are provided with shafts, and the opposite sides of side plate one and side plate two are provided with bearings connected to the shafts.

[0009] Furthermore, the tension sensor is cylindrical and is integrated at both ends of the tension roller.

[0010] Furthermore, the base fabric is arranged in an S-shape and passes around the guide roller, the guide roller, and the tension roller in sequence.

[0011] Furthermore, the tension roller is hollow inside and filled with damping rubber.

[0012] Furthermore, the end of the shaft core is rotatably connected to the transverse support arm; the outer side of the roller body is provided with an anti-slip layer.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] During the coating process, the base fabric is tensioned and driven by guide rollers and tension rollers to ensure the coating effect; and a tension sensor is integrated on the tension roller to detect the phenomenon of the base fabric being too tight or too loose due to the accumulation of errors in each step, further ensuring the coating effect.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Example 1, in conjunction with Appendix Figure 1 , 23. A geomembrane coating device, comprising a mounting frame installed inside the coating device to support each roller; specifically, the mounting frame includes symmetrically arranged side plates 1 and 2, with a roller 3 rotatably disposed between the side plates 1 and 2 and fixedly connected to several support rods 4; the roller 3 is located at the middle of the support rods 4; the support rods 4 are fixedly connected between the side plates 1 and 2 for support, improving the stability of the side plates 1 and 2 installed between the coating mechanism; the roller 3 is used to provide the included angle for base fabric transmission, ensuring transmission tension, and the roller 3 is located between the support rods 4 to prevent the support rods 4 from obstructing the transmission of the base fabric on the surface of the roller 3;

[0022] Based on the above, the roller 3 is equipped with shafts at both ends, and the opposite sides of side plate 1 and side plate 2 are equipped with bearings connected to the shafts; through the connection between the shafts and the bearings, the roller 3 can rotate smoothly, which facilitates the transmission of the base fabric and reduces resistance.

[0023] Combined with appendix Figure 1 , 2 1. Side plates 1 and 2 are provided with transverse support arms 5 on opposite sides. The transverse support arms 5 are rotatably connected to the roller 3. Specifically, the transverse support arms 5 are provided with through holes that can accommodate the roller 3, and they do not contact each other to avoid affecting the normal rotation of the roller 3.

[0024] The transverse support arm 5 is equipped with a guide roller 6 and a tension roller 7 that rotate between its two ends; the base fabric passes through the guide roller 6, the guide roller 3, and the tension roller 7 in an S-shape to achieve smooth transmission of the base fabric;

[0025] Based on the above, tension sensors 8 are provided at both ends of tension roller 7. The tension sensors 8 are cylindrical and integrated at both ends of tension roller 7. The cylindrical tension sensors 8 save installation space, have a high degree of integration, and can be disassembled and maintained as a whole with tension roller 7. Through the external controller and the detection values ​​of tension sensors 8, changes in the tension of the base fabric can be detected in a timely manner. The tension roller 7 is hollow inside and filled with damping rubber to reduce the weight of tension roller 7, thereby reducing the impact on the tension of the base fabric when it passes through.

[0026] Combined with appendix Figure 4 The tension sensor 8 is provided with a thrust ring 9 on its inner side. The thrust ring 9 is used to protect the tension sensor 8 and avoid damage caused by instantaneous impact, thereby reducing the failure rate.

[0027] Combined with appendix Figure 2 The tension roller 7 and the guide roller 6 both include a shaft core 10 and a roller body 11; the end of the shaft core 10 is rotatably connected to the transverse support arm 5, so that the guide roller 6 and the tension roller 7 can rotate smoothly and drive the base fabric; the outer side of the roller body 11 is provided with an anti-slip layer 12 to increase the friction between it and the base fabric.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
