Recently, the National Development and Reform Commission issued the "National Highway Network Plan (2013-2020)" to require overall arrangements and concentrate forces to accelerate the construction of ordinary national roads. Provincial Highway 210, Ya'an-Lushan-Baoxing-Xiaojin (Dawei) section is included in the plan as a section of National Highway 351 Taizhou-Xiaojin. In other words, the Provincial Highway 210 line will be named after the National Highway 351 in the future, and will become another national route after Ya'an City's National Road 108 and 318.

The 351 State Road started from Taizhou, Zhejiang Province, and entered Jiangxi through Pan'an, Dongyang, Yiwu, Pujiang, and Lanxi, connecting Hubei, and ending in Sichuan Xiaojin County.

According to Zhao Feiyong, chief of the Planning Department of the Ya'an Transportation Bureau, the Provincial Highway 210 line has been included in the “4·20” Lushan earthquake recovery plan after the devastating earthquake. It is preparing for the preliminary work of the project, and strives to start this year. Once the Provincial Highway 210 line is upgraded to a national road, its road grade, traffic capacity and resilience will all increase.

Foil Winding Machine

Process:

The foil roll is introduced into the rubber roller of the feeding device via the decoiling machine and then would in the winding former after passing through the edge of the shearing machine and the roller wheel of the burr pressing device. The inter layer insulation coil is erected in the rear of the coiling optical shaft of the foil winding machine and wound in the winding former after sheared by the trimming roll and the shears blade.

Functional feature:

1. The device adopts and electrical servo deflection correction system to achieve manual/automatic adjustment of the foil position more conveniently and reliably.

2. An advanced electrical control technology of constant tension is adopted to control the tension of the foil and the inter layer insulation, with the features such as quantitive, accurate and convenient control of the tension no mechanical friction. The required tension can be maintained for forward winding, stop and backward winding, ensuring compact coils.

3. The inter layer insulation adopts a cantilever mechanism, convenient for feeding and the mechanism can be pulled out as a whole without guide rails outside the body.

4. Automatic welding mechanism and roll shearing mechanism adopt ball screws and linear guide rails for drive, ensuring the service life and accuracy of the device.

5. This device first adopts the all-in-one sing frame, solving problems such as few coil urns and deflection correction lag.

6. This device is a hi-tech product produced by combining with actual production on the basis of many similar products at home and abroad. The whole machine is controlled via an advanced PLC touch screen, with high automation level and simple and reliable operation, representing higher production level of domestic foil winding machines.
