drum
Bag glue roller is belt conveyor transport system is the important component parts and. Rubber roller bag can effectively improve the operation of the transmission system, protect metal drum from the wear and tear, avoid skidding of conveyor belt, the drum and belt synchronous operation, so as to ensure the operation of belt and efficient, large capacity. Rubber roller bag also can effectively prevent the roller and sliding friction between the belt and reduce material bonded on the surface of the roller, thus reduce the belt running deviation and wear Widely used in: steel, metallurgy, coal, cement, power generation, chemical fertilizer, grain depot, port and other industries.

Package glue roller technology fall into two categories, the traditional plastic bags, such as heat vulcanized rubber packet technology, mainly through vulcanizing pot rubber and drum vulcanizing process, to ensure that encapsulates the panel and the bonding strength of roller, the second for cold vulcanization package adhesive technology, is the use of special way of cold vulcanized drum and its package panel direct bonding glue, can live encapsulates the downhole plastic bags, etc., its advanced technology at the same time also greatly reduces the labor costs.

Manufacturing folding

Generally in the spindle of drum, according to the loading conditions, can be divided into the following two kinds:

1) spindle under bending moment, such as the redirection roller group axis;

2) shaft under bending moment and torque at the same time, such as the transmission drum group axis;

Shaft material is generally after rolling or forging of carbon steel or alloy steel, common material is medium carbon steel, 45 # steel is the most commonly used, for axial force and larger size is restricted, and some special requirements of shaft alloy steels are available, and selection of material for the quad-zero chromium, according to the need, shaft generally need heat treatment or surface strengthening treatment, to improve its mechanical properties and wear resistance, etc., under the general temperature, alloy steel and carbon steel elastic modulus difference is very small, so using alloy steel can improve the stiffness of shaft;

Shaft conditioning treatment generally by the material aspect, for driving drum set, when the shaft does not meet the requirements of strength index can also choose to merge the tempering process, and according to the symmetrical cyclic bending allowable stress checking;

Drum skin design technical requirements for:

1) drum skin curly must be along the rolling direction of the steel plate;

2) the wrong side of the joint is greater than 1 mm;

3) rubber bag after the longitudinal weld ultrasonic or X-ray flaw detection inspection must be conducted:

(1) ultrasonic testing were 10%, weld up to the standard level 2;

(2) X-ray detector from one end of the 20% of the total length, weld up to level 2, general as unqualified detection length double, double still are not qualified for inspection, until it meets the requirements;

4) roll tube skin after the roundness tolerance should be no more than 0.5;

5) material: Q235 steel, yield strength of 235 cattle/square meter;

For medium-sized roller group and light roller, when the wheel is greater than 220 mm in diameter, cast steel, the light drum set, when the wheel diameter less than 220 mm, USES the hot rolled round steel, shall conform to the standard;
