Since June 18, there have been heavy torrential rain in Congjiang County of Guizhou, Songxi of Fujian, Khingan of Guangxi, Qingyuan of Zhejiang and Shaoguan of Guangdong. 

       Under the extremely heavy rainstorm, the waterlogging is serious, and has the possibility which causes the geological disaster, creates the big river big flood, threatens people's life and property security seriously. In addition, from June 20, the main rain belt will come to hunan-jiangxi-anhui-jiangsu, Zhejiang and Shanghai area. Under heavy rain, sandbags and other flood control materials appear to be particularly important, and sand bags, the general use of plastic woven bags, when it comes to woven bags, the production and processing process is closely related to linear motors, the processing flow of woven bag generally includes: PP, PE material → drying mixer → wire drawing machine → winder → circular loom → bag cutting machine → sewing machine → printing machine → PP woven bag → packing machine. The linear motor has been used in the winder. The Movement of the reciprocating wire arrangement of the traditional winder is a structure in which the slider moves in the spiral groove by the rotation of the reciprocating rod with the spiral groove, which realizes the rotation of the spiral groove into the reciprocating motion, it is easy to cause reciprocating spiral groove mechanical sliding wear and frequent addition of lubricating oil drawbacks, and spiral groove reciprocating rod is also very easy to wear, once wear maintenance cost is very high. 

     The Winder with the linear motor drives the butterfly disc directly to realize the linear reciprocating movement, and at the same time, it can change the reciprocating speed of the linear motor to realize the goal of all kinds of arrangement patterns. Kunshan Tongmao Electronics Co. , Ltd. is one of the few high-tech enterprises with the ability of R & D and CUSTOMIZATION OF LINEAR motors.
