Our company designed and produced "adjustable spring buffer roller group" can adjust the buffer elasticity according to the impact of the material on site, adjust the idling angle of the idler roller according to the height of the belt in the field so that the middle roller height is suitable for the belt height. Compared with other cushion roller group, it has the advantages of obvious protective belt effect, long service life and less material loss. And the greater the impact of the advantages of the more fully displayed.

This series of buffer roller group for my company's patented product.

Patent No .: ZL 94247277.2

 Structure Introduction

In the design of this series of roller group, we give full consideration to the roller group on the tape protection, but also take into account the use of reliability, durability and versatility. This series of roller groups suitable for installation in a variety of slot angle bracket type conveyor belt.

First, the structural characteristics

This series of roller group has three groups of rollers and movable detachable roller support frame, the support frame has the bottom beam and the active triangular pillar of the two major components.

The roller group uses the pressure spring as the buffer force source, and when the pressure spring is compressed, the spring force is increased with the decrease of the height, so that the idler roller group can effectively counteract the increase of the buffer force with the increase of the impulsive force Materials, the impact of falling, play a protective tape role.

The movable triangular bracket of the idler roller group can decompose the impact force acting on the roller pillar, which can effectively increase the impact resistance of the idler roller group and prolong the service life.

The roller group durable, can not afford to roll, roller-type unchanged. The tape protection effect is obvious.

Second, the bottom beam

Bottom beam for channel welding parts, its strength, stiffness, good stability. Overcome some of the big impact force by the buffer conveyor roller group of the bottom beam deformation of the shortcomings of the bottom beam on the tray for the 35 # steel casting, from the spring and control the role of the bottom roller in the control roller.

Third, the activities of triangular support column

The movable triangular support column is composed of the movable leg, the pressure spring and the guide pillar assembly, and is connected with the bottom beam.

The movable leg is a channel member with good rigidity.

The pressure spring is made of 60si2Mn spring steel, and each type of idler group is designed with three kinds of spring for selection.

The guide pillar assembly is both the guide column of the spring and the support column of the bottom stop point of the middle idler roller. Adjusting the compression nut on the pillar allows the roller set to arbitrarily select the groove angle and cushioning force in a certain range. So that there is a suitable backing for the receiving tape at any stage, including the transitional stage near the drum. To protect the tape, the purpose of extending the service life.
