All getter elements 3 are mounted on the same support 4. The support 4 extends from the end of the roll 1 to the outside of the roll 1. An intake passage 5 is provided in the support 4, the intake passage 5 communicating with the intake port 3a of each of the intake elements 3. Each suction hole 2 on the roll surface can periodically pass through the suction opening 3a of one of the suction elements 3 as the roll 1 rotates relative to the suction element 3.
The roll 1 may be a single component or a component formed by combining a plurality of components. The shape, number and arrangement of the suction holes 2 on the roll surface are determined according to the actual requirements of the equipment to which the suction roll is mounted.
A radial position adjusting mechanism connected with the air suction element 3 is arranged outside the roller 1. The radial position adjustment mechanism of this embodiment is a pneumatic mechanism. The pneumatic element 6 of the pneumatic mechanism is connected with all the suction elements 3 through the supporting piece 4, and the pneumatic element 6 can drive the suction elements 3 to move so as to change the radial position of the suction elements 3 in the roller 1. The pneumatic elements 6 are preferably air cylinders, the piston rods of which are connected to the support 4, and when the air cylinders drive the piston rods to extend and retract, the piston rods drive all the suction elements 3 together through the support 4, so as to synchronously change the radial positions of all the suction elements 3 in the roller 1. With the variation of the radial position of the getter elements 3 inside the drum 1, the getter opening 3a of each getter element 3 can be either attached to the inner wall of the drum 1 as in fig. 3 or detached from the inner wall of the drum 1 as in fig. 4. When the suction port 3a of the suction element 3 is kept close to the inner wall of the roller 1 as shown in fig. 3, the suction hole 2 on the roller surface can be communicated with the suction channel 5 in the supporting piece 4 as shown in fig. 2 and 3 in the process of passing through the suction port 3a of the suction element 3, and the suction hole 2 forms suction therewith, so that the material close to the roller surface can be adsorbed, and the adsorption function of the adsorption roller is realized. When the suction function of the suction roll is not required, the suction port 3a of the suction element 3 is kept separate from the inner wall of the roll 1 as shown in fig. 4, and at this time, the suction hole 2 on the roll surface is separated from the suction port 3a by a certain distance as shown in fig. 4 in the process of passing through the suction port 3a of the suction element 3, and suction force is not formed in the suction hole 2.
The shape of the getter element 3 is not limited to the one shown in the drawings, and may be determined according to actual needs.

The manner in which the drum 1 rotates relative to the suction element 3 depends on the actual requirements of the equipment in which the suction roll is installed, and for example, it may be that only the suction element 3 is fixed, that only the drum 1 is rotated, that only the suction element 3 is rotated about the axis of the drum 1, and that both the suction element 3 and the drum 1 are simultaneously rotated at a certain speed difference.
As another embodiment, the radial position adjusting mechanism may also adopt a crank-slider mechanism, wherein a crank of the crank-slider mechanism is connected with the motor, and a slider of the crank-slider mechanism is connected with the supporting member 4 shown in fig. 1, thereby forming a connection relationship with all the air suction elements 3. The motor drives the crank to rotate, the crank drives the sliding block to linearly move, and the sliding block drives all the air suction elements (3) to move together through the supporting piece 4, so that the radial position of each air suction element 3 in the roller 1 is changed. The motor for driving the crank to rotate can adopt a servo motor.
As another embodiment, the radial position adjusting mechanism may also adopt a rack-and-pinion mechanism, the gear of which is connected to the motor, and the rack of which is connected to the support 4 shown in fig. 1, so as to be in connection with all the getter elements 3. The motor drives the gear to rotate, the gear drives the rack to linearly move, and the rack drives all the air suction elements (3) to move together through the supporting piece 4, so that the radial position of each air suction element 3 in the roller 1 is changed. The motor for driving the gear to rotate can adopt a servo motor.
As a preferred embodiment, the end of the roller 1 is provided with an opening 8. As shown in fig. 5, the aperture of the opening 8 is large enough so that the getter element 3 and the support 4 can be moved together from the opening 8 into and out of the interior of the drum 1. This facilitates the installation and maintenance of the getter element 3 and the support 4. The openings 8 may be provided at both ends of the drum 1 or may be provided at only one end of the drum 1.
An embodiment in which the suction roll shown in fig. 1 is applied to one apparatus is shown in fig. 6. The apparatus of fig. 6 is an apparatus for processing sheet-like products, and may be, for example, a rewinder for winding paper into a roll, or a paper towel folder, and the suction roll of fig. 1 may be, accordingly, a rewinder roll, or a paper towel folder roll. As shown in fig. 6, the support bearing 9 of the suction roll is mounted on the frame 10 of the apparatus and is sleeved on the outer wall of the roll drum 1 of the suction roll, and the pneumatic element 6 in the radial position adjusting mechanism is mounted on the frame 10 of the apparatus.
