Description

Technical Field

[0001] The utility model relates to the technical field of cardboard conveyors, and more specifically, to a deviation rectifying mechanism for a cardboard conveyor. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made by processing various pulp and composed of interwoven fibers. During the production and processing of cardboard, a conveyor is needed to transport it, but the cardboard is prone to deviation during transportation.

[0003] After retrieval, the utility model patent with the publication number of CN214827524U discloses a deviation rectifying and conveying device for cardboard production, including a device body. A cross plate is fixedly connected to the inner wall of the device body. A conveyor belt is arranged on the top of the cross plate. Symmetrically distributed vertical rods are slidably connected in the cross plate. The top ends of the vertical rods are fixedly connected with a rectifying plate. An installation plate is fixedly connected to the top of the rectifying plate. Place the cardboard on the top of the conveyor belt. The output shaft of the second motor rotates to drive the moving block to move. The moving block drives the rectifying plate to move, so that the rectifying plate fits with both sides of the cardboard, so that the position of the cardboard will not deviate during transportation. The output shaft of the first motor rotates to drive the threaded rod to rotate and then drive the threaded sleeve to move downward. The downward movement of the threaded sleeve makes the pressure roller closely adhere to the cardboard, avoiding the two sides of the cardboard from warping during transportation. At the same time, under the action of gravity, the sliding plate slides on the inner wall of the sleeve, thereby buffering part of the force on the device body, and the use effect is good.

[0004] However, the above patent still has the following deficiencies: Although the rectifying plate can limit and rectify the conveyed cardboard, the long-term contact and friction between the cardboard and the inner side of the rectifying plate are likely to cause wear to it, thus affecting the rectifying effect; and during the rotation of the conveyor belt, friction will also occur between the side part of the conveyor belt and the side part of the conveyor frame, which will also cause wear to the conveyor belt. At this time, the conveyor belt will be inclined during transportation, resulting in the conveyed cardboard being inclined and moving forward, and at the same time, it will increase the friction between the cardboard and the rectifying plate. For this reason, we propose a deviation rectifying mechanism for a cardboard conveyor. Content of the Utility Model
