Description

Belt conveyor idler with cleaning function

Technical Field

The utility model belongs to the technical field of cigarette cut-tobacco making, and particularly relates to a belt conveyor carrier roller with a cleaning function.

Background

The belt conveyor is widely applied to a production line of a modern cigarette production line, is an important auxiliary device for connecting an upper host device and a lower host device, and is mainly used for conveying tobacco leaf related materials. In the conveying process, the materials are directly contacted with the surface of the conveying belt, and due to the characteristics of the materials, part of tobacco foam or tobacco fragments are easily adhered to the conveying belt and move along with the conveying belt.

The deflection regulating carrier roller is arranged at the bottom of the conveying belt and is in close contact with the surface of the conveying belt, and the deflection regulating carrier roller mainly plays a role in supporting and adjusting the conveying belt. When the conveyor belt is in operation, part of tobacco foam or fragments moving along with the conveyor belt can adhere to the deflection regulating carrier roller, and the tobacco foam or fragments are accumulated on the deflection regulating carrier roller more and more, and finally a layer of thick tobacco foam fragment scale is formed on the deflection regulating carrier roller. After the surface of the deviation-adjusting carrier roller forms scale, the diameter of the deviation-adjusting carrier roller and the surface of the deviation-adjusting carrier roller are changed due to the scale, and the scale has certain viscosity, so that phenomena such as deviation, deformation, burrs, tearing and the like are easy to occur in the running process of the conveyer belt.

At present, as no scale cleaning device is arranged on the offset idler, the workshop lists the removal of the scale on the surface of the offset idler in one of the periodic maintenance projects, and a manual removal method is generally adopted, or the idler which is difficult to remove or has serious scale is removed for manual cleaning and then is installed. The manual cleaning method is that the common shovel blade is adopted to remove the scale deposit in the stop state, operators need to operate at the bottom of the belt in the cleaning process of the common shovel blade, a certain potential safety hazard exists, the cleaning is incomplete and untimely, the shovel blade is easy to slip off and stab the belt due to excessive force for removing the scale deposit, and the scale deposit on the surface of the deflection-regulating carrier roller is removed due to the lack of effective cleaning tools and frequent disassembly and cleaning, so that the labor intensity is high, the working efficiency is low, and the potential safety hazard is extremely high.
