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 shown in the 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.

Example one

Referring to simultaneously fig. 1, fig. 2, fig. 3, the adsorption roller of the present invention includes a roller 1, and the roller surface of the roller 1 is provided with a plurality of suction holes 2 penetrating the roller surface. The whole roller 1 can be a single part or a component formed by combining a plurality of parts. The shape, number and arrangement of the suction holes 2 on the roll surface depend on the actual requirements of the installation in which the suction roll is equipped.

A mandrel 3 is arranged in the roller 1. The shape of the mandrel 3 is not limited to a circular tube, and may be, for example, a square tube. An air exhaust channel 4 is arranged in the mandrel 3. A plurality of sealing blocks 5 arranged along the axial direction of the mandrel 3 are arranged between the mandrel 3 and the inner wall of the roller 1. The sealing block 5 is fixed to the outer wall of the mandrel 3 by screws 6. The inside of each sealing block 5 is provided with an air flow passage 7 communicating with the suction passage 4. The air flow channel 7 penetrates to the surface of the sealing block 5 to form an air suction port 8. The periphery of the air suction port 8 is tightly attached to the inner wall of the roller 1. As the roller 1 rotates relative to the sealing block 5, the suction holes 2 in the roller surface periodically pass through the suction openings 8 of the sealing block 5. In the state shown in fig. 1 to fig. 3, the air suction holes 2 on the roller surface pass through the air suction port 8 of the sealing block 5, and the air suction holes 2 are just aligned with the air suction port 8 of the sealing block 5, at this time, the air exhaust channel 4 in the mandrel 3 can exhaust air to the air suction holes 2 on the roller surface through the air flow channel 7 in the sealing block 5, and the air suction holes 2 form suction force therewith, so that materials close to the roller surface can be adsorbed, and the adsorption function of the adsorption roller is realized. In order to increase the wear resistance of the sealing block 5, the sealing block 5 may be made of a wear resistant material or a layer of wear resistant material may be provided around the suction opening 8 of the sealing block 5. The wear resistant material layer may be, but is not limited to, graphite, plastic.

As shown in fig. 1 and 3, the central axis of the mandrel 3 is offset from the central axis of the roller 1 in the direction towards the suction opening 8 of the sealing block. Therefore, the flow path of the suction air flow from the suction holes 2 on the roller surface to the interior of the mandrel 3 is short, the resistance of the air flow is reduced, the energy consumption is reduced, and meanwhile, the radial size of the sealing block 5 can be reduced, and the manufacturing cost is reduced.

As shown in fig. 1, the support 9 supporting the mandrel 3 is disposed outside the roll 1, the support 9 not being connected to the roll 1. A sliding bearing 10 is arranged between the mandrel 3 and the support 9, and the mandrel 3 and the support 9 form a sliding connection relationship. The mandrel 3 can slide axially back and forth along the support 9, but cannot rotate, constrained by the support 9. Referring to fig. 4 and 5, after the mandrel 3 moves a certain distance in the axial direction, the air suction port 8 of each sealing block 5 deviates from the rotating surface of the air suction hole 2 on the roll surface, so that the air suction hole 2 on the roll surface cannot pass through the air suction port 8 of the sealing block 5 no matter what angle the air suction hole 2 rotates along with the rotation of the roller 1, and the air suction hole 2 is maintained in a non-suction state, thus the adsorption roll is in a working state without adsorption function. In this way, by moving the mandrel 3 axially back and forth and switching the mandrel 3 between the two positions shown in fig. 1 and 4, the suction roller can be switched between the two operating states of having the suction function and not having the suction function.

Because the support piece 9 of support dabber sets up in roller 1 outside, support piece 9 is not connected with roller 1, so need not to set up the spare part of being connected with dabber 3 in roller 1, has reduced the processing and the assembly degree of difficulty of absorption roller, also makes things convenient for the clearance in dabber 3's dismantlement and roller 1 inner chamber simultaneously.

An embodiment in which the suction roller shown in fig. 1 is applied to an apparatus is shown in fig. 6. The apparatus in fig. 6 is an apparatus for processing sheet-like products, and may be, for example, a rewinding machine for winding paper into a roll, or a tissue folding machine, and accordingly, the suction roll shown in fig. 1 may be used as a rewinding roll of the rewinding machine, or as a folding roll of the tissue folding machine.

As shown in figure 6, a bearing 11 for supporting the roller 1 is sleeved on the outer wall of the roller 1, and the bearing 11 is fixed on a frame 12 of the equipment. The support 9 of the support mandrel 3 is fixedly connected with a slide 13. The slide 13 is slidably connected to the frame 12 of the apparatus. The sliding direction of the slider 13 is perpendicular to the axis of the mandrel 3. A locking screw (not shown) is connected between the sliding block 13 and the frame 12, and the sliding block 13 is locked and fixed on the frame 12 by the locking screw. When the radial position of the mandrel 3 in the roller 1 needs to be adjusted, the position of the supporting piece 9 in the direction perpendicular to the axis of the mandrel 3 can be adjusted by loosening the locking screw between the sliding block 13 and the machine frame 12 and moving the sliding block 13, so that the radial position of the mandrel 3 in the roller 1 is adjusted. And after the adjustment is completed, the locking screw is screwed again.

The apparatus shown in fig. 6 is also provided with a drive mechanism that reciprocates the mandrel 3 in the axial direction. The driving mechanism comprises an air cylinder 14 fixed on the frame 12, and a piston rod of the air cylinder 14 is connected with the mandrel 3. The mandrel 3 is reciprocated in the axial direction by the cylinder 14. As another embodiment, a crank-slider mechanism may be used as the driving mechanism for driving the mandrel 3 to reciprocate in the axial direction.
