Description

Technical Field

[0001] The utility model relates to the technical field of parallel rollers, in particular to a parallel roller with a telescopic adjustment function. Background Art

[0002] Rollers are important components of belt conveyors. They are used to support the conveyor belt and the materials carried on it, ensuring the stable operation of the conveyor belt. Rollers are divided into parallel rollers, grooved rollers, self-aligning rollers and buffer rollers.

[0003] At present, parallel rollers are composed of an axis and a roller sleeve rolled from a steel plate. Since the roller sleeve adopts an integrated molding technology, the length of the parallel roller cannot be adjusted. Therefore, it cannot be adjusted according to the width of the conveyor belt during use. For conveyor belts of different widths, parallel rollers of different lengths need to be replaced, which is more troublesome during operation. Therefore, it is necessary to design a parallel roller with a telescopic adjustment function. Utility Model Content

[0028] Specifically, the length of the parallel rollers is first adjusted according to the width of the conveyor belt. When adjusting the length of the parallel rollers, the handle 303 is turned, and the movable plate 302 can be driven to move with the cooperation of the screw rod 301, and then the second roller 2 can be driven to slide inside the first roller 1, so that the distance between the two rollers can be changed to achieve the purpose of changing the length of the parallel rollers; after the length of the parallel rollers is adjusted, the screw rod 301 is locked by the locking assembly 4 to prevent the screw rod 301 from rotating, which is conducive to the parallel rollers maintaining the required length; then the load-bearing wheel 6 on the parallel roller is placed on the roller frame, which makes it convenient for the parallel rollers to support the conveyor belt, which is conducive to the stable operation of the conveyor.
