16,Dec,2019Visits: 4

  Roller conveyor is very suitable for the transportation of all kinds of bags, pallets and other items. It is mainly used to transport bulk materials, small items or irregular items, which need to be placed on the idler or in the turnover box for transportation. It can transport single heavy items, or bear large impact load. The roller lines are easy to connect and filter. Multiple roller lines and other conveyors or special units can be used Become a complex logistics transportation system, complete many aspects of the process needs. The stacking roller can be used to realize the stacking and conveying of materials. Roller conveyor has the characteristics of simple structure, high reliability, convenient use and maintenance.

  Roller conveyor is very suitable for the transportation of all kinds of bags, pallets and other items. It is mainly used to transport bulk materials, small items or irregular items, which need to be placed on the idler or in the turnover box for transportation. It can transport single heavy items, or bear large impact load. The roller lines are easy to connect and filter. Multiple roller lines and other conveyors or special units can be used Become a complex logistics transportation system, complete many aspects of the process needs. The stacking roller can be used to realize the stacking and conveying of materials. Roller conveyor has the characteristics of simple structure, high reliability, convenient use and maintenance.

  

  Due to the poor sealing performance at both ends of ordinary carbon steel drum, in the environment of strong corrosion, high temperature and serious dust, the corrosive components in the environment easily enter into its interior from the gap at both ends, resulting in rust or rust death of the roller bearing, resulting in increased wear of the conveyor belt, virtual increase, short service life and even tear, which not only increases the production The production cost will also affect the production efficiency of the conveyor directly because of frequent shutdown maintenance and replacement of parts.

  

  In order to solve the problem that the friction of the carbon steel roller in the roller conveyor is large, and the periodic is short and the tearing is strong, the carbon steel roller with better sealing can be used. The structure basically supports the rotating shaft. The steel pipe coated with wear-resistant rubber layer is arranged concentrically on the outer side of the rotating shaft. Bearings are set at both ends of the pipe body and between the rotating shaft and the steel pipe respectively. The bearing pedestal is matched with the outer circumference of the steel pipe in the way of interference. At the same time, labyrinth seals are set between the outer end of the bearing pedestal and the rotating shaft, including the clearance sleeve through the central hole The inner surface of the end cover is provided with two to four first circular convex rings, the inner cover is arranged between the bearing and the end cover, and the second circular convex ring which is staggered with each other is arranged on the end face of the inner cover of the first circular convex ring toward the end cover. In order to further improve the sealing performance, the outer end of the end cover can also be provided with a convex plate, and there is an interference fit between the end cover and the shaft The mechanical structure can effectively improve the sealing between the shaft and the bearing, between the bearing and the steel pipe, effectively prevent the corrosive components in the air from entering the conveyor drum, thus avoiding the abrasion or rust death of the sealing parts caused by the rusty shaft, obviously improving the sealing performance of the product, prolonging the service life of the conveyor drum, reducing the replacement rate, and thus reducing the replacement rate The ordering cost of users saves limited resources.

  

  In addition, due to the above structural design, the carbon steel roller can also have the bearing capacity of ordinary steel roller, which can further improve the running stability of roller conveyor, and is very suitable for the transportation of chemical industry, food industry and pharmaceutical industry.
