Problems solved by technology

[0003] Existing vacuum adsorption rollers usually use rubber sealing strips for direct sealing, forming a single closed adsorption chamber through the sealing strips. The rubber sealing strips tend to age and lose elasticity after working for a period of time, which affects the sealing effect. In addition, relying on a single rubber sealing strip Sealing, not only needs to be replaced frequently, which increases the maintenance cost, but also the rubber sealing strip is easy to stick to the vacuum adsorption roller after aging, which increases the difficulty of replacement

Abstract

The invention discloses a vacuum adsorption roller used for a folding machine and belongs to the field of adsorption rollers. The vacuum adsorption roller comprises a core shaft and a roller body, wherein the core shaft is in the roller body; the core shaft and the roller body are coaxially and rotatably connected; a chamber is formed between the outer axial plane of the core shaft and the inner axial plane of the roller body; the vacuum adsorption roller for the folding machine further comprises a sealing device; and the sealing device is positioned between the core shaft and the roller bodyand divides the chamber into an adsorption cavity and a decompression cavity. The vacuum adsorption roller for the folding machine adopts the sealing device formed through combination of a spring anda sealing strip for sealing to replace the direct sealing manner of the single rubber sealing strip, the sealing effect is excellent, and the maintenance is convenient to achieve; in addition, only one vacuum pump is needed for working, so that the noise is small, and the energy consumption is low; and moreover, the vacuum pump continuously supplies pressure for air exhaust to reduce the time difference of intermittent air exhaust, so that the vacuumizing speed is further increased.

Description

technical field [0001] The invention relates to the field of suction rolls, in particular to a vacuum suction roll used in a folding machine. Background technique [0002] During the mechanical processing of thin sheet materials such as toilet paper, the film coil is driven on the roller shaft. In order to avoid slipping between the film and the roller body and uneven force on the traction film, the film is easy to wrinkle and tear. If the problem of cracking occurs, the roller shaft often adopts a vacuum adsorption roller. Vacuum adsorption roller is a kind of roller shaft that adopts negative pressure to adsorb the film tightly on the roller body, and absorbs the coiled material through vacuum to make it close to the roller body to prevent the coiled material from slipping. [0003] Existing vacuum adsorption rollers usually use rubber sealing strips for direct sealing, forming a single closed adsorption chamber through the sealing strips. The rubber sealing strips tend t...
