Information

The 2nd Belt Transfer Roller manufacturer tells you that belt conveyors are widely used in industrial production as a general-purpose equipment that can be continuously conveyed. Compared with the roller conveyor, it has the conveying capacity of bulk materials and small items. The rollers, which are one of the core components of belt conveyors, have different types according to their respective roles and functions. The following questions are often overlooked:
1.Can the roller be used for tensioning?

The manufacturer of 2nd Belt Transfer Roller tells you that roller support is one of the belt support methods widely used in belt conveyors. It can effectively reduce the frictional resistance during transportation, and is more suitable for long-distance transportation or large overall load transportation occasions. However, please do not use the roller (roller) that supports the belt for various forms of belt tensioning. Even if the contact wrap angle is not too large, the tension generated may cause fatal damage to the roller.
2.Is the idler roller an ordinary unpowered roller?
The manufacturer of 2nd Belt Transfer Roller tells you that the unpowered roller runs passively, and the roller rotates only when the goods pass by, which is of low intensity. As for the idler, the belt is the cargo, and they are in uninterrupted operation. At this time, the problem of static electricity is often ignored, and appropriate measures must be taken in the design of the idler to remove the large amount of static electricity generated by the high-speed friction between the roller and the belt. (The same applies to bottom belt friction conveyors)
3. How to reduce the running noise of the roller?
The noise originates from the vibration of the idler during high-speed operation, so first of all, ensure that the connection between the roller and the frame is not "loose". In this regard, the performance of the internal thread installation method will be significantly better than that of the spring press-in type. Of course, other measures can also be taken to eliminate the gap between the shaft core and the mounting hole of the frame after the latter is installed. In addition, it is recommended to use the Damon Industrial 1200 series. The design of its silent bearing assembly also has excellent performance in terms of sound absorption and noise reduction that other products do not have.
4. How to make the drive roller "half the effort"?
The 2nd Belt Transfer Roller manufacturer tells you to choose a large-diameter drive roller as much as possible. At this time, you will find that the belt conveyor becomes particularly "powerful". In addition, you can also coat the outer surface of the driving roller with polyurethane (or rubber) to increase the friction and improve the driving ability. However, it is not recommended to knurl it. This is indeed a means to increase friction, but it will cause damage to the belt, accelerate belt damage, and shorten the life of the belt.
5. Is there any simple and economical correction design?
Deviation correction (also known as "deviation adjustment") is a problem that all belt conveyors have to face, especially when two-way conveying is required. The manufacturer of 2nd Belt Transfer Roller tells you that it is a systematic project and requires a special correction mechanism design. When there is no special application such as lateral feeding that has a large axial force, it is recommended to use a drum design, that is, the two ends of the roller are processed into a certain taper, so that it has a certain self-correcting function.
6. The high-speed belt roller should be adjusted for dynamic and static balance.
The manufacturer of 2nd Belt Transfer Roller tells you that due to the uneven internal organization of the raw materials and the shape and position errors formed by the processing, in fact, when the roller is running, the center of mass of the revolving body does not completely coincide with the center of revolving, and it is in an unbalanced state. At high speeds, it will cause strong vibration of the roller and even the machine body, accelerate bearing wear, shorten the mechanical life, and cause destructive accidents in severe cases. According to different applications, Damon Industry can provide you with belt rollers that have been adjusted to meet the requirements of dynamic and static balance.
7. Selection of the diameter of the head and tail rollers.
The manufacturer of 2nd Belt Transfer Roller tells you that when the belt conveyor adopts intermediate drive instead of end drive, it is not recommended to choose a large diameter for the head and tail rollers. It will increase the gap between the front and rear conveyors and easily cause cargo jams.
The above is the sharing of some belt conveyor roller designs and selections that the 2nd Belt Transfer Roller manufacturer told you. I hope to help everyone!
