Description

Production device for ring threaded sling

technical field

The utility model relates to the field of hoisting tools, in particular to a production device for an annular wire threading hoisting belt.

Background technique

The ring threading sling is widely used in various fields such as daily life and hoisting. It has the characteristics of flexible and convenient use and high structural strength. Most of the existing ring-shaped slings directly connect the two ends of a strip-shaped sling or connect the two ends through a fixed structure. Due to the existence of joints, the strength of the sling of this structure is not high, especially its joints are prone to breakage. On the other hand, it is also difficult to fix the two ends, and the production process is complicated. In order to improve the strength of the ring-shaped sling, many slings are made of harder materials. Although these slings can improve the strength, they will bounce outward once they break, causing damage to the surrounding people and objects. security risks.

For this reason, someone has designed a kind of non-joint endless wire threading sling that is made by continuous loop winding mode, and the device that produces this ring threading wire sling. At present, this annular wire threading sling has been applied, but due to its structural characteristics, there are still relatively large defects. The reason is: because it is made by continuous loop winding, it is difficult to grasp the tightness of the wire during the winding process, and the processing is difficult, and as the number of winding turns increases, the length of each turn will also change. . In this way, some coils of the annular wire threading sling made by winding are longer, and some coils are shorter, which will cause uneven force during use. The shorter coil bears most of the force, and it will break after long-term use; while the longer coil cannot bear the load, resulting in waste of raw materials. Although people have made more improvements to the production device for a long time, they still cannot obtain satisfactory results. The quality of the products produced by the production device with simple structure and low cost is poor; while the production device with complex structure and expensive cost can make the length of the coil tend to be consistent to a certain extent, but it still cannot completely solve the problem, and the working stability is difficult. Guaranteed, less controllable.
