No power roller factory outlets

First, no power drum Overview: English translation: roll, roller drum cylindrical parts, sub-driving and driven rollers. Widely used, such as rotary screen printing machine, digital printers, transportation equipment, paper and packaging machinery, and other transmission delivery system. Usually made of seamless steel tubes, also depending on the need to use different processes such as aluminum 6061T5,304L / 316L stainless steel, 2205 duplex stainless steel, steel castings, forged steel solid core of material. Drum roll main body early production car, static balance early school head interference shaft assembly welding, fine cars and fine balancing school and other processes components. If the tolerance for behavior such as roundness, cylindricity and straightness requirements of 0.2mm or less, after the finishing required on cylindrical grinder or roll grinders grinding. Surface hardness requirements, the need to increase the heat treatment process. After the roll forming, for rust and corrosion, wear and support needs, you also need a surface treatment or coating such as painting, galvanizing, TEFLON spray, rubber-coated, chrome, ceramic painting and oxidation processes. Second, resolve without power type cylinder: 1) Analysis by parameters: 1, classified according to size, a large machinery, such as paper rolls (length can reach 10 meters in diameter, 1500mm above), there is a small automatic on line with the flat belt conveyor idlers (usually less than 1 m long) or less, diameter are 159mm 2, according to the role of points, there to ensure the accuracy of the transfer roller, such as digital laser printer, there is pressure from filter effects such as calender roll paper machinery, there are less demanding support for dimensional accuracy with rollers, heat exchange requirements for roll, heavy pressure filtration also play the role of the roller, etc., to name a few. 3, the drum diameter choice: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm. 4, roller material selection: galvanized steel, chrome steel, carbon steel coated, aluminum, stainless steel, ABS and so on. Roller type selection: non-powered roller, single chain roller, duplexes roll, "O" with a roller, tapered roller, groove roller. 5, roller fixation: spring loaded type, within the tooth axis, all flat tenon, through shaft pin hole. 2) Press the barrel material can be divided into the following categories: 1, steel drum, that drum cylinder with steel pipe processing; 2, plastic rollers, the roller cylinder with a plastic pipe processing; according to the cylinder surface treatment divided into the following categories: 1, plating drum, that drum surface plating, a common zinc, can also be chrome, nickel; 2, spray drum, that drum surface spray powder can also be used the way painting treatment; 3, including plastic drum, drum surface that is encapsulated, it can pack a variety of colors of rubber, soft roller surface, reducing wear and tear of the goods. Third, non-powered roller tongue drum of the difference between full-flat 1, the whole flat tongue drum (DSWZ-03) using the ends of the shaft flat tenon way, with easy installation, flexible rotation features. 2, no power roller (DSW series) DSW series of roller is to learn and absorb foreign advanced technology, combined with the characteristics of China's logistics transportation, and carefully developed a new series of roll developed, with a reasonable structure, flexible rotation, bearing good, low noise and appearance appearance and other characteristics, widely used in light industry, machinery, electronics, food, metallurgy, medical and other industries. 3, through the pin hole axis drum (DSWZ-04) using the shaft perforated plug connection, having a bearing good, low noise characteristics. Fourth, the technical parameters of the drum without power: no power adapter is easy to filter between the drum, the drum can be used multiple lines and other transportation equipment or plane consisting of complex logistics transportation system and split merge system, complete the wide range of technology needs. 1, the length of the delivery of the object, the width and height; 2, each conveyor unit weight; 3, the bottom of the status of material to be transported; 4 requirements (for example, on whether the special working environment: humidity, temperature influence, chemicals, etc. ); 5, conveyor belong without power type or motor driven formula. To ensure a smooth delivery of goods, at any point in time must have at least three roller held in contact with the conveying thereof. Soft bag was necessary, Gato plate delivery. Fifth, the choice of a non-dynamic drum, drum length selection: different widths of the goods should be selected for the width of the drum, the "delivery was + 50mm" under normal circumstances. 2, the drum wall thickness and shaft diameter options: according to the weight of material to be transported evenly to the contact roller, calculate the required load each cylinder to determine the thickness and shaft diameter drum. 3, roller materials and surface treatment: Depending on the environment of transport, the material used to determine the roller and surface treatment (galvanized carbon steel, stainless steel, black or encapsulated). 4. Select the drum installation: according to the specific requirements of the overall conveyor roller installation choice: spring loaded type, within the tooth axis, all flat tenon, through shaft pin hole and the like. Bend machine for tapered roller, which roll surface and taper depending on goods size width and turning radius may be.
