Description

Technical Field

[0001] This utility model relates to the field of tensioning structure technology, specifically to a transmission belt tensioning pressure bar structure. Background Technology

[0002] In the textile industry, many textile machines rely on drive belts to achieve efficient power transmission, such as key equipment like spinning machines, weaving machines, and knitting machines. However, prolonged and high-intensity operation causes the elasticity of the drive belt to decrease. In addition, the strong mechanical vibration generated during equipment operation and the continuous high-speed friction between the drive belt and pulleys make the drive belt very prone to loosening during use.

[0003] If a transmission belt becomes loose, it will cause a series of serious production problems. The most direct problem is a significant reduction in transmission efficiency, with excessive slippage between the belt and pulleys, resulting in substantial power loss during transmission and an inability to efficiently drive driven components. Simultaneously, a loose transmission belt can cause instability in textile machinery operation. In the spinning process, belt instability leads to uneven yarn tension, resulting in yarns of varying thicknesses and severely impacting product quality. Furthermore, during weaving, abnormal transmission belt operation can interfere with the interlacing of warp and weft yarns, causing fabric defects and a significant increase in the defect rate.

[0004] Currently, traditional methods of tensioning transmission belts, such as manually adjusting the pulley spacing or using pressure bar rollers, are cumbersome, time-consuming, and labor-intensive. In modern large-scale textile production, frequent manual intervention is not only inefficient but also prone to delays due to negligence, affecting production continuity. Therefore, we consider designing a pressure bar structure that can reliably tension the transmission belt, reducing the need for frequent manual adjustments and addressing the problem of belt deformation and loosening. In view of this, we propose a transmission belt tensioning pressure bar structure. Utility Model Content
