According to the conveying process requirements, single roller closed belt conveyor can be a single delivery, can also be more than one component or with other conveying equipment to form horizontal or inclined conveyor system, in order to satisfy different layout of production line. The device can be in the environment temperature from 20 to + 40 within the scope of use, the temperature of the conveying material under 50 . Fully enclosed by the single roller belt conveyor head part, fuselage, tail section, conveyor belt and site safety device. (1), the nose section is the core part of transport operations, including motor, reducer, hydraulic coupling, coupling, main drive roller, sweeper and headstock gear. Belt nose department is mainly to provide power for logistics, transportation by drum as a driving force to complete the material delivery. (2), body parts including roller, frame, etc., used to drive and support the conveyor belt. In belt conveyor, roller conveyor belts role is to support, to reduce drag conveyor belt movement, and makes the conveyor belt of the sag does not exceed a certain limit, to ensure the transport belt running smoothly. Rack is conveyor support frame, used to support roller, conveyor belt, to ensure the normal operation of belt conveyor. Conveyor frame type determined by the type of conveyor. (3), general by shell, bearing, the belt conveyer tail no guard hollow cylinder driven roller and tensioning device. For common faults in the process of roller conveyor in actual use, we focus on single roller design, the design of the feeding hopper, cleaning device back design, the design of the tensioning device, and the design of the sealing structure has been optimized in aspects of innovation, in order to prolong the service life of belt conveyor accessories, increase belt chance the stability and reinforcement of sealing machine. The traditional belt conveyor design concept is belt and rollers linear velocity is consistent, belt and roller friction small, therefore, the traditional belt conveyor roller on the same shaft diameter is consistent, the new single roller belt conveyor design idea think on the same shaft roller diameter can be inconsistent, the design concept of innovation has brought the revolution of belt conveyor. Single roller rotation of power needed by the belt and roller friction is passed to the roller, the size of the belt and roller friction decides the performance of the single roller belt conveyor. Under a certain speed, belt and roller friction is smaller, the smaller the output. Under the ideal condition, the conveyor belt running resistance will be smaller, the largest output. Therefore, the innovation of the single roller design in time is the reasonable choice under the certain tape speed of roller parameters, in order to achieve the best effect. Tensioning device design is the key, the role of the tensioning device is a guaranteed supply with enough tension, to produce the necessary friction between roller and the conveyer belt; Second is to limit the conveyor belt between the supporting roller sag, make tape transfer function to work properly. The main purpose of the sealing device is wind, rain, prevent dust emission and material 4 loss. In the improved design of the single roller belt conveyor, adopted a fully enclosed structure, greatly improved the working environment, with external wind dust network Settings, full enclosed the single roller belt conveyor can meet the requirements for open working environment and pollution to the environment very high operational areas. Conveyor are running, to check the roller in time, found that the roller damage or rotation is not flexible to change in time, ensure the conveyor in good working condition; Found to rectify the conveyor belt running deviation, make the belt conveyor to keep good running state. Strengthen field management, strict operation mechanism, seriously implement equipment maintenance inspection requirements in the specification. Belt conveyor in our country has a wide application range, can be used for a variety of wet and dry powder, granule, block material transportation, transport volume, transport distance is long, little resistance during operation, energy consumption, small restricted by terrain conditions, on the way to loading and unloading of goods, simple operation, stable operation, easy maintenance; But tape are susceptible to wear and tear, and the slope is not too big, high friction, easy to pollute the environment and transporting powdery and granular materials, so this design can reduce the environment pollution, and reduce the friction to avoid excessive wear of belt. At the same time in developing the conveyor level have obvious improve, high power, long distance belt conveyor of new technology and new product development research have made great achievements. The belt conveyor is one of the most ideal efficient continuous transportation equipment, compared with other equipment has obvious advantages. Therefore, not only can be used in short distance transportation, also can be used in long distance transmission. So in the continuity of production and has played a very important role in automation, improve the labor productivity. Conveyor series products is becoming more and more production, more batch is big, and the key technologies of conveyor and its main part has carried on the theoretical research and product development. But there are still insufficient in many ways, compared with abroad, installed power is small, transport capacity is poor, and the largest conveyor belt width is small, face only half as much as that of the foreign transport length has a big gap between the reliability and life expectancy, so the design cant solve all problems of conveyor, but it does to a certain extent, improve the state of conveyor. With the development of belt conveyor in our country, is widely applied in each department. To improve the ordinary belt conveyor in our country, perfect the corresponding structure, first of all with a single roller fixed belt prevent running deviation. At the same time, the conveyor plus a shield to prevent damage to the environment. Again, screw tightening device ensure machine operation reliability and stability. To some extent, these can guarantee the performance of the belt conveyor, the belt speed is fast, transport volume, high efficiency and energy saving environmental protection. Make more widely conveying material sort, wider scope of transmission capacity, transmission of stronger adaptability, loading and unloading is more flexible, high safety reliability, with good prospects for development. Totally enclosed the single roller belt conveyor is fully enclosed structure, the waterproof performance is good, dust not in public, environmental protection performance is good, the moving parts including roller
