Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Refer to simultaneously figure 1, figure 2, figure 3, the adsorption roller includes a roller 1, is equipped with a suction manifold 2 and many radial suction branch 3 that run through the suction manifold in the roller 1. The suction manifold 2 extends axially through the drum 1 from the end of the drum 1. The branch suction pipes 3 are arranged along the axial direction of the main suction pipe 2. The roller surface of the roller 1 is provided with air suction holes 4 penetrating through the roller surface. The shape, number and arrangement of the suction holes 4 on the roll surface depend on the actual requirements of the installation in which the suction roll is fitted.

The suction manifold 2 is supported by a support 5 arranged outside the roller 1, the suction manifold 2 being stationary. The support 5 may be a simple metal bracket, which is connected to the suction manifold 2 by welding, screwing, or the like. The support 5 may be mounted on a frame of the apparatus to which the suction roller is fitted. The roller 1 is connected with a driving mechanism of the device. When the equipment works, the driving mechanism drives the roller 1 to rotate.

The through holes on the tube wall of the suction main tube 2 are in sliding fit with the suction branch tubes 3. The branch suction pipes 3 are freely slidable in the radial direction of the main suction pipe 2. A sealing sleeve 6 is fixed at a through hole of the suction manifold 2 penetrated by the suction branch pipe 3. The sealing sleeve 6 is sleeved on the air suction branch pipe 3 to play an air-tight role and prevent the air suction flow from leaking from the through hole on the pipe wall of the air suction main pipe 2. The sealing sleeve 6 can be welded on the pipe wall of the suction manifold 2 or integrally formed with the pipe wall of the suction manifold 2.

One end of each air suction branch pipe 3 is an air suction port 3a, and the other end is provided with a slide block 7 which is connected with the air suction branch pipe 3 in a sliding way. The slide block 7 is slidably sleeved in the suction branch pipe 3. The slider 7 may be made of, but not limited to, graphite, plastic. A spring 8 which is pressed between the slide block 7 and the air suction branch pipe 3 is arranged in the air suction branch pipe 3. Under the action of the spring 8, the slide block 7 and the branch air suction pipe 3 simultaneously press against the inner wall of the roller 1, so that the air suction port 3a of the branch air suction pipe 3 is tightly attached to the inner wall of the roller 1. With the rotation of the roll 1 relative to the suction manifold 3, the suction holes 4 on the roll surface periodically pass through the suction ports 3a, so that the suction holes 4 on the roll surface periodically form a negative pressure. The air suction end of the air suction branch pipe 3 is fixed with a wear-resistant head 9, the air suction port 3a is arranged on the wear-resistant head 9, and the wear-resistant head 9 is in close contact with the inner wall of the roller 1. The wear head 9 may be made of, but not limited to, graphite, plastic.

Each of the branch suction pipes 3 is provided with a vent hole 3b communicating with the lumen of the main suction pipe 2. The air suction branch pipe 3 is communicated with the cavity of the air suction main pipe 2 through an air hole 3.
