1. Due to insufficient baffle length, the baffle length should be adjusted and extended until the material on the conveyor belt is stable.

2.裙边开档不合适所致。裙边开档应该是输送带宽度的2/3—3/4，块状物料时应窄一些。裙边更好呈扇形（开口顺着运行方向），并能调整开度大小。

2. Improper opening of skirt. The opening of skirt should be 2 / 3-3 / 4 of the width of conveyor belt, and it should be narrower for block materials. The skirt should be fan-shaped (the opening is along the running direction), and the opening can be adjusted.

3.输送带和挡板的间隔不合适。先把挡板的输送带运行方向一侧与输送带相触，之后慢慢加大间隔到适当位置，以减少挡板对输送带的磨损。

3. The distance between conveyor belt and baffle is not suitable. First contact the running direction side of the conveyor belt of the baffle with the conveyor belt, and then slowly increase the interval to the appropriate position to reduce the wear of the baffle to the conveyor belt.

4.投料方向不合适，即物料落下的方向与输送带运行方向不同，以致产生横向力，使输送带跑偏或受磨损加剧，应调整落料方向。

4. The feeding direction is not suitable, that is, the falling direction of the material is different from the running direction of the conveyor belt, resulting in the generation of transverse force, which makes the conveyor belt deviate or wear more seriously. Therefore, the blanking direction should be adjusted.

5.挡板的材质不合适。挡板材质过硬，或者使用旧输送带而帆布露出，以致直接与输送带接触，应选用合适的橡胶挡板。

5. The baffle material is not suitable. If the baffle material is too hard, or the old conveyor belt is used and the canvas is exposed, so that it directly contacts with the conveyor belt, appropriate rubber baffle should be selected.

6.物料的落料角度和落差不合适所致。应减少角度，使物料落在输送带上不弹跳。落差大而输送带受到很大冲击时，应采取措施，以降低投料时的速度

6. Improper blanking angle and drop of materials. The angle should be reduced so that the material will not bounce when it falls on the conveyor belt. When the drop is large and the conveyor belt is greatly impacted, measures should be taken to reduce the feeding speed

7.物料的落料速度不对所致，由于物料的落料速度和输送带的速度调整得不好，物料落在输送带上的瞬间打滑，由此磨损上盖胶时，要调整落料速度，使之与输送带速度一致。

7. The wrong blanking speed of the material. Due to the poor adjustment of the blanking speed of the material and the speed of the conveyor belt, the material falls on the conveyor belt and slips instantly, so when the upper cover rubber is worn, the blanking speed should be adjusted to be consistent with the speed of the conveyor belt.

8.下托辊粘有物，不转动或没调整好，上盖胶异常磨损，应采取如下几种方法：安装清扫器、清洗输送带、在返回辊上安装橡皮套、修理或更换返回辊。

8. If the lower idler sticks to something, does not rotate or is not adjusted properly, and the upper cover rubber is worn abnormally, the following methods should be adopted: install the sweeper, clean the conveyor belt, install the rubber sleeve on the return roller, repair or replace the return roller.
