[0002] The safety net is woven with materials such as nylon rope. The main body, braided rope and tie straps of the safety net are all woven and twisted. The mesh holes are mostly diamond or square. When under force, the ropes between each mesh hole are connected together to form a strong pulling capacity, thereby protecting the safety of people and goods.
[0003] When weaving a safety net, it is necessary to use equipment such as a warp knitting machine to process the wire ropes. At this time, the raw materials of the safety net are pre-wound on the drum. During the transportation process, it is inevitable to use a tension mechanism to tighten the transported wire ropes to prevent the wire ropes from loosening and causing knots. However, in the past, such adjustment mechanisms often guided the movement of the wire ropes through rollers with fixed positions, making it difficult to adjust the speed of the wire rope transfer and unable to control the tension, which made it quite inconvenient to use.
[0004] Now, a new tension adjustment mechanism of a warp knitting machine for producing safety nets is proposed to solve the above problems. Utility Model Content
