为了尽量减少进料口保送带的磨损，进料口的构造设计应满足以下条件：
In order to minimize the wear and tear of the feeding belt, the structure design of the feeding belt should satisfy the following conditions:
a）进料和保送带运转方向相同。在进料过程中，物料以简直与保送带相同的速度挪动。
A) The feeding and conveyor belts operate in the same direction. In the process of feeding, the material moves at almost the same speed as the delivery belt.
b）保送带上物料的等效自在落体高度小于1米，使保送带上的冲击力尽可能小。
B) The equivalent free falling height of the material on the delivery belt is less than 1 meter, so that the impact force on the delivery belt is as small as possible.
c）给料斜槽设有带式筛，使细料先落在保送带上，为大料提供缓冲。
C) The feeding chute is equipped with a belt sieve to make the fine material fall on the delivery belt first and provide buffer for the large material.
d）设计合理的溜槽和导向溜槽，使物料连续落在保送带的中心；
(d) Design reasonable chutes and guide chutes so that materials can continuously fall in the center of the delivery belt;
e）导向槽的挡板宽度沿保送带方向越来越窄。此外，导槽应延伸到物料的速度，以到达皮带的速度。
E) The baffle width of the guide groove becomes narrower and narrower along the direction of the delivery belt. In addition, the guide groove should extend to the speed of the material to reach the speed of the belt.
f）进料段应坚持程度或倾斜不超越8度，进料段应装置缓冲辊或对槽辊加密。
F) The feeding section should be adhered to or inclined not exceeding 8 degrees, and the feeding section should be equipped with buffer roll or groove roll encryption.
另外，溜槽和导向槽应固定结实，使其正确地靠在保送带上，导向底部不能离保送带太近。
In addition, chutes and guide grooves should be fixed and firm, so that they can be positioned correctly on the delivery belt, and the bottom of the guide should not be too close to the delivery belt.
换向滚筒与保送带磨损
Wear of reversing drum and delivery belt
倒转滚筒位于保送机尾部，保送带随倒转滚筒一同旋转，使下保送带成为上保送带停止物料保送。
The reverse drum is located at the tail of the conveyor. The conveyor belt rotates with the reverse drum, so that the lower conveyor belt becomes the upper conveyor belt and stops material delivery.
维护措施
Maintenance measures
（a）在换向鼓外表左近装置刮刀板。刮料板与刮料板整体焊接。刮料板用螺栓固定在保送架上，刮料板与滚筒倾斜一定角度，以增加刮料才能。
(a) A scraper plate is installed near and left on the outer surface of the reversing drum. The scraper plate and scraper plate are welded as a whole. The scraper plate is fixed on the guaranteed shelf with bolts. The scraper plate and the drum are inclined at a certain angle to increase the scraper ability.
b）在倒转鼓前部装置V型打扫器（用螺栓与机架衔接），打扫器与保送带接触端装置橡胶条，减少皮带磨损。其构造如下图所示：
B) A V-type sweeper is installed at the front of the inverted drum (connecting the bolt with the frame), and a rubber strip is installed at the contact end of the sweeper and the delivery belt to reduce belt wear. Its structure is shown in the following figure:
此外，为处理倒转鼓前无支撑段漏料的问题，也可在无支撑段装置挡板，以减少漏料。
In addition, in order to deal with the problem of material leakage in the unsupported section before the inverted drum, baffles can also be installed in the unsupported section to reduce material leakage.
皮带跑偏形成的部分磨损
Partial wear due to belt deviation
保送带跑偏是保送带常见毛病，主要是保送带运转时，保送带中心线偏离保送带纵向中心线。
Escort belt deviation is a common problem of the escort belt, mainly when the escort belt is running, the center line of the escort belt deviates from the longitudinal center line of the escort belt.
维护措施
Maintenance measures
（a）头尾鼓不平行，呈现跑紧跑不松现象。
(a) Head and tail drums are not parallel, showing the phenomenon of running fast and not loose.
假如整个保送机的中心线有偏向，则需求重新校准中心线；假如只要细微偏向，则能够拧紧轴承座。但这种办法只能调整较小的偏移量。关于较大的偏移量，可将尾鼓装置在挪动小车上（见下图），并可调整小车以纠正偏向。
If the center line of the whole delivery machine is biased, the center line needs to be recalibrated; if only slightly biased, the bearing seat can be tightened. But this method can only adjust the smaller offset. For larger offset, the tail drum can be installed on the moving car (see figure below), and the car can be adjusted to correct the deviation.
b）由于保送带自身弯曲不直或接头不正确，招致保送带负载不平均，形成跑偏。保送带应切割、重新粘合或钉牢。
B) Due to the incorrect bending of the belt itself or incorrect joints, the load of the belt is uneven, resulting in deviation. The belts should be cut, re-bonded or pinned.
c）托辊组轴线与保送带中心线不垂直，形成保送带运转后不向前运转，即保送带向后运转（与保送带方向相反）。假如调整办法是偏离哪一侧，则哪一侧的托辊将偏离保送带行进方向24度（见下图），普通状况下，应调整几个托辊以纠正偏向。
C) The axis of the supporting roller group is not perpendicular to the center line of the belt, forming that the belt does not run forward after running, that is, the belt runs backward (opposite to the direction of the belt). If the adjustment method is to deviate from which side, then which side of the idler will deviate from the direction of the delivery belt 2 to 4 degrees (see figure below). Under normal conditions, several idlers should be adjusted to correct the deviation.
惰轮和传送带之间的磨损
Wear between idler wheel and conveyor belt
维护措施
Maintenance measures
（a），确保整个保送机处于中心线上；其次，两侧倾斜托辊与中间程度托辊具有相同的倾斜角度。一切中间托辊均在同一程度面上，使一切托辊与保送带接触良好，以保证各托辊受力平均。
(a) Firstly, ensure that the whole delivery machine is on the central line; secondly, the inclined idlers on both sides have the same inclination angle as the intermediate idlers. All intermediate idlers are on the same level, so that all idlers are in good contact with the belt to ensure the average force of each idler.
b）尽量减少运用调心辊。
B) Minimize the use of aligning rollers.
c）增强托辊的日常维护，及时改换损坏的托辊。
C) Enhance the daily maintenance of idlers and replace damaged idlers in time.
