Problems solved by technology

However, this slow-down splicing process will inevitably cause changes in the tension of the material, increasing the instability of the product, increasing the reject rate, and even causing splicing failure due to the increase in tension, affecting the production speed of the product and causing waste. The requirements for materials are also relatively high; if slow-down splicing is not used, the production speed of the machine must be limited within 120 m / min to ensure stable production of the machine, which will affect the production efficiency and economic benefits of the manufacturer
Speed-down splicing is used, which will have a certain impact on the quality of the machine's products and the stability of the equipment.

The present invention has high automatic constant-tension splicing speed up to 200 m / min, stable splicing, high splicing quality and high production efficiency.

Description

technical field [0001] The invention relates to production equipment of disposable sanitary products, in particular to a constant tension splicing device for strip-shaped non-woven fabric substrates. Background technique [0002] At present, disposable sanitary products are mostly made of non-woven materials. The linear speed of disposable sanitary products equipment in the industry is 120 m / min to 180 m / min, and the splicing of strip non-woven substrates is spliced ​​at reduced speed. However, this slow-down splicing process will inevitably cause changes in the tension of the material, increasing the instability of the product, increasing the reject rate, and even causing splicing failure due to the increase in tension, affecting the production speed of the product and causing waste. The requirements for materials are also relatively high; if slow-down splicing is not used, the production speed of the machine must be limited within 120 m / min to ensure stable production of t...
