Description

Technical Field

[0001] The utility model relates to the technical field of roller adjustment, in particular to a bidirectional adjustment device for a grooved roller. Background Art

[0002] Belt conveyors are widely used in all walks of life in national production and play an irreplaceable role in social development. Some are used to transport bulk materials, and some are used to transport finished items. They can be operated continuously or in conjunction with the process in the production process to form a rhythmic flow operation transportation line. When the belt conveyor is running, if there are factors such as insufficient tension, eccentric accumulation of materials, frame deformation, roller bearing defects, misaligned installation, skewed joints, and uneven tension distribution, the conveyor belt will deviate. For example, the patent with publication number CN207174761U discloses a trough-type The roller group includes a roller group, a roller bracket, a base bracket, a base, an angle lifter, a first connecting piece, a second connecting piece and a fixed frame. A guide groove is provided on the groove wall of the angle lifter; the first connecting piece passes through the guide groove to connect with the roller bracket, and the first connecting piece is horizontally arranged in the angle lifter; the second connecting piece is longitudinally arranged in the angle lifter, one end of the second connecting piece is connected to the first connecting piece, and the other end passes through a fixing hole arranged on the upper end face of the angle lifter, and the second connecting piece is sleeved with a first and a second nut, and the first and the second nuts are arranged above and below the fixing hole; the fixed frame is connected to the angle lifter and arranged above the first nut. Through the guide groove structure in the angle lifter, the first connecting piece is connected to the supporting leg of the roller bracket to move up and down in the guide groove, and the height of the first connecting piece is controlled by a nut.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a two-way adjustment device for a trough type roller, comprising a fixed bracket 1, both ends of the fixed bracket 1 are equipped with a movable bracket 2, the fixed bracket 1 is rotatably matched with a first roller body 3, the movable bracket 2 is slidably matched with a slide bar 5, a first support frame 7 is fixed on the slide bar 5, a second support frame 8 is fixed on the movable bracket 2, ball heads 10 are installed on the first support frame 7 and the second support frame 8, and a second roller body 4 is installed between the two ball heads 10.

[0022] In this embodiment, the movable bracket 2 is fixedly connected to the fixed bracket 1 by bolts, a slide groove 6 is opened in the movable bracket 2, the slide groove 6 corresponds to the slide rod 5, the slide rod 5 and the movable bracket 2 are fixedly connected by bolts, a rotating shaft 13 is installed in the second support frame 8, the ball head 10 located on the second support frame 8 is fixedly connected to the rotating shaft 13, the rotating shaft 13 is rotatably connected to the second support frame 8, one end of the rotating shaft 13 is threadedly matched with a second nut 14, and ball bowls 11 are installed at both ends of the second roller body 4, and the ball bowl 11 corresponds to the ball head 10.

[0023] Specifically, when it is necessary to adjust the angle according to the transport direction of the conveyor belt, it is only necessary to slide the slide bar 5 so that the slide bar 5 slides out of a part of the slide groove 6, and then fix the position of the slide bar 5. At this time, the first support frame 7 and the second support frame 8 are misaligned, and then the second roller body 4 is installed with the first support frame 7 and the second support frame 8 through the ball bowl 11 and the ball head 10, so that the second roller body 4 is tilted.

[0024] A screw rod 9 is installed in the first support frame 7. The ball head 10 on the first support frame 7 is fixedly connected to the screw rod 9. The screw rod 9 is threadedly matched with the first support frame 7. Two first nuts 12 are installed on the screw rod 9. The two first nuts 12 are respectively located on the upper and lower sides of the first support frame 7.

[0025] When the up and down angles of the second roller body 4 need to be adjusted, the screw rod 9 is rotated to make the screw rod 9 move upward relatively until it is adjusted to a suitable height, and then the first nut 12 is rotated to fix the screw rod 9. At this time, the height between the two ball heads 10 changes, and then the second roller body 4 is installed with the first support frame 7 and the second support frame 8 through the ball bowl 11 and the ball head 10, so that the up and down inclination angle of the second roller body 4 can be changed.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
