In the 17th century, the United States began to use aerial ropeways to transport bulk materials; in the mid-19th century, various modern conveyor belt conveyors appeared one after another. In 1868, belt conveyors appeared in the United Kingdom; in 1887, screw conveyors appeared in the United States; in 1905, steel belt conveyors appeared in Switzerland; in 1906, inertial conveyors appeared in the United Kingdom and Germany. Since then, conveyor belt conveyors have been affected by technological advances in machinery manufacturing, electrical machinery, chemical and metallurgical industries, and have been continuously improved, gradually completing the transfer from the interior of the workshop to the completion of material handling within the enterprise, between enterprises and even between cities. An integral part of the mechanization and automation of material handling systems.
Conveyor belt conveyors are constantly being improved by the technological advancement of machinery manufacturing, electrical machinery, chemical industry and metallurgical industry. They are gradually improved from the completion of the delivery of the workshop to the completion of material handling within the enterprise, between enterprises and even between cities, becoming material handling. An integral part of system mechanization and automation.
First, the conveyor belt should be kept clean during the transportation process and the stop process, and should be cleaned frequently. In addition, avoid direct sunlight or rain and snow immersion, prevent contact with materials such as acid-base oils and organic solvents, and keep away from the heating device at least one meter away.
Second, the type, structure and number of conveyor belts should be selected according to the actual conditions. This will be better to use.
Third, the conveyor belts of different types and specifications can not be put together, and the joints are preferably glued for adhesion.
Fourth, the conveyor belt running speed should not be lower than 2.5 m / s, some of the more viscous materials use a device with strong fixed force for unloading assembly, take a low speed. Www.jialianlw.com from Jialian Automation Equipment
5. The conveyor belt receiving section should shorten the roller spacing and take buffering device. In order to prevent leakage, the belt side should adopt a relatively flexible material blocking plate to avoid the material blocking plate being too hard, scraping the belt surface of the conveyor belt, and selecting the appropriate one. In order to reduce the impact on the tape when the material is landed, a chute should be adopted to reduce the material landing interval.
6. The diameter of the transmission drum of the transporter and the supporting of the conveyor belt, the drive roller, the reversing drum and the bracket angle should be planned according to the design of the conveyor, which must be reasonable.
7. When there is a conveyor belt falling off, it must be installed in time to prevent the conveyor belt from working in case of problems. It is strictly forbidden to smash the goods directly on the conveyor belt at a high place. The goods placed on the conveyor belt must be smooth, and cannot be placed obliquely or horizontally. It is strictly prohibited to use the overload. In use, carefully check whether the conveyor belt runs abnormally, such as deviation. If abnormal phenomena such as deviation are found, it must be adjusted and repaired in time.
