The invention discloses an anti-pollution and anti-winding roller which comprises a rolling wheel and a shaft, two bearings are arranged between the rolling wheel and the shaft, and the two bearings are limited through a step arranged on the rolling wheel and a clamping spring arranged on the shaft; one end of the shaft extends out of the rolling wheel to form an extending end, and the other end of the shaft is located on the inner side of the rolling wheel to form a non-extending end. A dustproof blank cap is arranged on the side, close to the non-extending end, of the rolling wheel, and a through cover allowing the shaft to penetrate through is arranged on the side, close to the extending end, of the rolling wheel. Compared with the prior art, the anti-pollution and anti-winding rolling wheel is provided with the two bearings, so that the coaxiality of the shaft and the rolling wheel is improved, and the service life of the rolling wheel is prolonged; besides, one side of the rolling wheel is provided with a dust-proof blank cap, and the other side of the rolling wheel is provided with a through cover through which the shaft can penetrate, so that muddy water and thin film fragments can be effectively prevented from entering the rolling wheel.

    本申请公开了一种防污染防缠绕的滚轮,包括滚动轮和轴,所述滚动轮和所述轴之间设置有两轴承,两所述轴承通过设置在所述滚动轮上的台阶和设置在所述轴上的卡簧进行限位;所述轴的一端伸出所述滚动轮形成伸出端,所述轴的另一端位于所述滚动轮的内侧形成未伸出端;所述滚动轮上靠近所述未伸出端的一侧设置有用于防尘的闷盖,所述滚动轮上靠近所述伸出端的一侧设置有可供所述轴穿过的通盖。与现有技术相比,上述防污染防缠绕的滚轮设置有两轴承,一是提高轴与滚动轮的同轴度,二是延长滚轮使用寿命;另外,所述滚动轮一侧设置有用于防尘的闷盖,另一侧设置有可供所述轴穿过的通盖,可有效防止泥水及薄膜碎片进入滚轮内部。
