Analyze the application of belt conveyor in tobacco processing industry

Belt conveyor is a continuous conveyor with flexible conveyor belt as material load and traction. The dryer mesh belt is a machine that uses static friction to transport materials in a continuous manner by friction drive. With it, the material can be formed on a certain conveyor line from the initial feeding point to the final unloading point to form a material conveying process. The belt conveyor has large conveying capacity, simple structure, convenient maintenance, standardized parts, etc. Advantages, widely used in mining, metallurgy (content: extracting metals or metal compounds from ore), coal and other industries. It is used to transport loose materials or finished items. According to the requirements of the transportation process, it can be transported by a single unit or composed of multiple units. Or it can be combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of operation lines. It is suitable for conveying bulk density less than 1.67/ton/m3, easy-to-pick powder, granular, and small lumps. Abrasive materials and bagged materials, such as coal, gravel, sand, cement (materials: powdery hydraulic inorganic cementitious materials), fertilizers, grains, etc. The temperature of the delivered material is less than 60°C. The captain and assembly form can be determined according to user requirements, and the drive can be an electric drum or a drive device with a drive frame. Logistics conveyor belt belt with traction parts The conveyor belt generally includes: traction parts, load-bearing members, driving devices, tensioning devices, redirecting devices and supports. Traction parts are used to transmit traction, which can be conveyor belts, traction chains or steel wire ropes (consisting of steel wires, rope cores and grease); load-bearing components are used to carry materials, including hoppers, brackets or spreaders, etc.; assembly line people and The effective combination of the machine fully reflects the flexibility of the equipment. It organically combines the conveying system, the accompanying fixture, the online special machine, and the testing equipment to meet the assembly requirements of a variety of products. According to the friction transmission principle, the power is transmitted to the active roller by the motor and roller transmission chain, and the active roller drives the conveyor belt to move continuously to realize the continuous conveying of materials. 1. Application type of belt conveyor The tobacco processing industry needs to transport a variety of materials, such as tobacco bags, tobacco, and tobacco stalks. According to the specific weight of the material, processing temperature, humidity, transportation angle, the accuracy (precision) of the equipment itself and the installation location of the equipment, choose different conveyor belts to match the corresponding transportation equipment. When the conveying angle is between 50°C and 75°C, the super hoist is used to transport materials. The equipment adopts an endless belt composed of a flat belt, a skirt edge, a horizontal baffle and a guide belt. In the equipment for storing and transporting semi-finished and finished products, such as feeders and storage cabinets, this equipment fixes the conveyor belt on a long-pitch loading conveyor chain, and the transmission system drives the conveyor chain to move on slide rails to transport materials. 2. The main structure of the belt conveyor. The belt conveyor is mainly composed of the head device, the tail device, the body section, the active roller, the passive roller, the lower roller, the loading conveyor belt, the cleaning device, the ash unloading device, the ash collecting device, and the frame And the transmission system. The conveyor belt of the tobacco processing industry generally adopts food grade, and the transmission system generally adopts a gear reducer.

Ash collection device Ordinary belt conveyor structure diagram (1) belt The loading conveyor belt in the belt conveyor is not only a bearing part, but also a traction part. It not only has bearing capacity, but also has sufficient strength. belts are usually composed of coating materials and core cloth. The core cloth is under tension (explanation: mutual traction when objects are under tension). The coating material protects the core from damage and corrosion. The core cloth is made of cotton, polyester yarn and polyester fabric. In the tobacco processing industry, PVC, PU, u200bu200bPE, TPE and double-sided canvas are commonly used as coating materials for conveyor belts. (2) Drive system The drive system of the belt conveyor is composed of a motor, a reducer, a sprocket, a transmission chain, an active roller, a passive roller and a bearing seat. Mesh belt conveyor transportation machinery can not only complete the transportation of bulk materials, but also transport finished materials, but depending on the place of use, working environment, and the type of materials to be conveyed, there will be big differences in its design and application.
