Description

Technical Field

[0001] This utility model relates to the field of polyethylene composite belt production and processing technology, and in particular to a composite belt tension control device. Background Technology

[0002] For corrosion protection of steel pipe bends used in oil and gas transmission, polyethylene composite tape is typically used. Professional manufacturers mechanically install the polyethylene composite tape, which is usually 50-120mm wide. To ensure production efficiency, multiple composite tapes are wound up simultaneously. However, due to inconsistent tension among the tapes, manual winding is required for each tape, resulting in high labor costs. If one person is used to wind the tapes simultaneously to reduce labor costs, the uneven tension among the tapes will lead to uneven winding and eventual collapse. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite belt tension control device.

[0004] The purpose of this utility model is achieved through the following technical solution: a composite belt tension control device, including a mounting frame, which is mounted on a working frame. The upper and lower ends of the mounting frame are respectively provided with an upper guide roller and a lower guide roller. A cylinder is also provided on the mounting frame. The piston rod on the cylinder is connected to the mounting seat. A pull roller is provided on the mounting seat, and the pull roller, the upper guide roller and the lower guide roller are arranged in a triangular distribution.

[0005] Preferably, the mounting bracket is provided with a slide rail, a slider is slidably mounted on the slide rail, and a cylinder is provided on the surface of the slider.

[0006] Preferably, the surface of the roller is provided with a limiting groove.

[0007] This utility model has the following advantages: This utility model uses a cylinder to drive the pull roller to move horizontally, thereby adjusting the distance between it and the upper and lower guide rollers. Furthermore, the pull roller, upper guide roller, and lower guide roller are arranged in a triangular pattern, which allows the stretching length to be close to twice the cylinder stroke, increasing the adjustment length and keeping the composite belt in a taut state at all times, thus ensuring neat winding and preventing collapse.

[0018] In this embodiment, as Figure 1 and Figure 2 As shown, a composite belt tension control device includes a mounting frame 1, which is mounted on a working frame 10. An upper guide roller 3 and a lower guide roller 2 are respectively installed at the upper and lower ends of the mounting frame 1. A cylinder 6 is also installed on the mounting frame 1, with a piston rod connected to a mounting base 8. A pull roller 7 is installed on the mounting base 8, and the pull roller 7, upper guide roller 3, and lower guide roller 2 are arranged in a triangular pattern. The cylinder 6 drives the pull roller 7 to move horizontally, thereby adjusting the distance between it and the upper guide roller 3 and lower guide roller 2. The triangular arrangement of the pull roller 7, upper guide roller 3, and lower guide roller 2 allows the stretching length to be approximately twice the stroke of the cylinder 6, increasing the adjustment length and ensuring the composite belt 4 is always under tension, thus guaranteeing neat winding and preventing collapse. In this embodiment, the composite belt 4 is sequentially bonded to the surfaces of the upper guide roller 3, the pull roller 7, and the lower guide roller 2, and one end of the composite belt 4 is connected to the existing winding machine 11. When using this device, only one operator needs to observe the tension of each composite belt 4. When it is found that the tension of a certain composite belt 4 is insufficient (not bonded to the surface of the upper guide roller 3, the pull roller 7, or the lower guide roller 2), the operator activates the corresponding cylinder 6. The piston rod on the cylinder 6 will drive the pull roller 7 to move, thereby stretching the composite belt 4 and keeping it in a taut state, ensuring neat winding and preventing collapse. In other words, when using this device for winding, only one person is needed to adjust the tension of each composite belt 4, thereby reducing labor costs. The winding machine 11 here is existing equipment and has not been improved; it is wound using existing methods and will not be described in detail here. This device is only used to adjust the tension of each composite belt 4 to keep it in a taut state.

[0019] Furthermore, the mounting bracket 1 is provided with a slide rail 5, and a slider 9 is slidably mounted on the slide rail 5. A cylinder 6 is provided on the surface of the slider 9. Specifically, the position of the cylinder 6 is adjusted by adjusting the position of the slider 9 on the slide rail 5.

[0020] Furthermore, such as Figure 3 As shown, a limiting groove is formed on the surface of the roller 7. Specifically, the main function of the limiting groove is to position the composite belt 4 and prevent it from shifting.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
