Description

Transition idler set and belt conveyor

Technical Field

The utility model relates to the technical field of conveying devices, in particular to a transition carrier roller set. The utility model also relates to a belt conveyor comprising the transition carrier roller set.

Background

The carrier rollers are important components of the belt conveyor, and are various in variety and large in number. The roller takes up 35% of the total cost of a belt conveyor and bears more than 70% of resistance, so the quality of the roller is particularly important. The carrier roller is used for supporting the weight of the conveying belt and the materials. The carrier roller must be flexible and reliable in operation. The friction force between the conveyor belt and the carrier roller is reduced, and the service life of the conveyor belt accounting for more than 25% of the total cost of the conveyor is played a key role. While idlers are a relatively small component in a belt conveyor, the construction is not complex, it is not easy to manufacture high quality idlers.

The transition carrier roller group is an important part for the transition section of the head and tail of the belt conveyor, generally two groups or more groups are matched for use, and are used for gradually transiting the bearing adhesive tape and materials from the bearing section to the central line of the roller, and the transition section is called as a transition section. In the traditional design, firstly, according to the bandwidth, the tension utilization rate and the adhesive tape type of the belt conveyor, the length of the minimum transition section (the projection length of the distance from the first group of normal groove-shaped carrier roller groups to the central line of the roller in the running direction of the adhesive tape machine) is comprehensively calculated, and then the transition carrier roller groups are arranged according to the length. However, when the transition roller set is arranged, the actual length of the transition section is always not smaller than the minimum length of the transition section, but is not a fixed length value, so that the roller of the transition roller set may not be in fit with the theory of the adhesive tape surface, or the adhesive tape is locally jacked up due to the transition fit of the transition roller set and the adhesive tape, when the material is conveyed, the situation not only can cause the overflow of the material in the transition section, but also causes the abrupt stress change when the adhesive tape moves to the transition section, and especially the edge of the adhesive tape is adversely affected, so that the service life of the adhesive tape is shortened.

Therefore, how to enhance the universality of the transition roller set and further prolong the service life of the adhesive tape is a technical problem to be solved by the technicians in the field.
