The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, an anti-sticking powder material packaging bag includes a bag body 1 and an auxiliary component 3. A blanking bag opening 2 is connected to the lower end of the bag body 1. The blanking bag opening 2 is bent upward to block the bottom of the bag body 1, facilitating the loading of powder materials. A reinforcing piece 4 is installed at the upper end of the bag body 1, and a handle 5 is connected to the upper end of the reinforcing piece 4. A bundling rope 6 is arranged outside the blanking bag opening 2. The bundling rope 6 is used for bundling and sealing the blanking bag opening 2, and an衔接绳7 is connected to the end of the bundling rope 6. The衔接绳7 is穿装在加固片4内侧避免捆绑绳6的下落,衔接绳7的收紧还可用于加固片4的收紧,用于袋体1的顶部收口,袋体1的下端设置有底固板9,底固板9在袋体1底部起到辅助承托的作用,避免因粉末重力导致袋体1的下部突出,且底固板9的端部安装有安装绳10,安装绳10用于底固板9的安装固定,安装绳10端部的外部设置有连接架11,且连接架11的形状为匚字形。

[0023] As Figure 2 shown, the auxiliary component 3 for preventing powder from sticking to the wall and remaining is arranged on the inner wall of the bag body 1. The auxiliary component 3 includes a scraping plate 301, a counterweight 302, an elastic rope 303, a movable hole 304, and an衔接板305. A counterweight 302 is installed at the upper end of the scraping plate 301. The outer wall of the scraping plate 301 is in contact with the inner wall of the bag body 1. The counterweight 302 provides the weight for the scraping plate 301 to slide down during powder blanking, so that the scraping plate 301 scrapes the inner wall of the bag body 1 when sliding down, avoiding sticking to the wall. An elastic rope 303 is connected to the upper end of the counterweight 302. The elastic rope 303 is used for connecting the scraping plate 301. A movable hole 304 is arranged outside the elastic rope 303. The movable hole 304 is used for the elastic rope 303 to extend into and be received in the hollow衔接板305. The scraping plate 301 and the counterweight 302 are arranged in parallel, and the outer diameters of the scraping plate 301 and the counterweight 302 are consistent with the inner diameter of the bag body 1.

[0024] As Figure 3 shown, a limiting component 8 for the衔接绳7 is arranged on the inner wall of the reinforcing piece 4. The number of the limiting components 8 is the same as that of the reinforcing pieces 4. The limiting component 8 includes a limiting buckle 801 and a connecting piece 802. The limiting buckle 801 is used for the installation of the connecting piece 802, and a connecting piece 802 is arranged outside the limiting buckle 801. The connecting piece 802 cooperates with the reinforcing piece 4 to limit the衔接绳7. It should be noted that there seems to be some incorrect or unclear expressions in the original text, such as "衔接绳7穿装在加固片4内侧避免捆绑绳6的下落" and some parts about "衔接板305" which may need further clarification for more accurate translation. The above translation is based on the best understanding of the current text.

[0025] In summary, the anti-sticking wall powder material packaging bag is firstly based on Figure 1-Figure 3 , when bagging, the bag opening 2 is bent upward to block the bottom of the bag body 1, and the binding rope 6 is used to bind and seal the bag opening 2, and the connecting rope 7 at the end of the binding rope 6 is inserted into the inner side of the connecting piece 802 and the reinforcing piece 4, and then the powder is loaded into the bag opening 2 and the inner wall of the bag body 1 for holding the powder material. After the powder is full, the connecting rope 7 is pulled to tighten the reinforcing piece 4 for closing the top of the bag body 1. When unloading, the connecting rope 7 and the binding rope 6 are removed, and under the gravity of the powder, the bag opening 2 moves downward and unfolds for unloading the powder. At the same time, the counterweight block 302 provides the weight for the scraper plate 301 to slide down when the powder is unloaded, so that the scraper plate 301 scrapes the inner wall of the bag body 1 when it slides down to avoid sticking to the wall.
