Compression roller device

Abstract

The invention discloses a compression roller device which comprises a shell. End covers used for sealing an inner cavity of the shell are arranged at the two ends of the shell. Multiple discs are arranged on the outer surface of the shell in a sleeving manner. A hollow pipeline is arranged in the shell in the axial direction. An air inlet connector communicating with the interior of the hollow pipeline is arranged on the hollow pipeline. A screw rod is arranged in the hollow pipeline in the axial direction of the hollow pipeline, and the screw rod is sleeved with multiple screw rod nuts. The screw rod nuts are sleeved with multiple drive rings. The drive rings are in sealing contact with the inner wall of the hollow pipeline and divide the hollow pipeline into multiple sealing cavities. Air cylinders used for pressing the multiple discs and distributed in the axial direction of the shell are arranged at the bottom of the shell, and air inlet holes which are in one-to-one correspondence with the air cylinders and drive piston rods of the air cylinders to act are formed in the shell. Pipeline exhaust holes in one-to-one correspondence with the air inlet holes are formed in the hollow pipeline. By means of the compression roller device, the requirement for changing of material specifications can be met, in addition, the structure is simple, and the difficulty of troubleshooting can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of tire building machines, in particular to a pressing roller device. Background technique [0002] The pressure roller device of the tire building machine is composed of many pressure roller discs, each disc is driven by a relatively independent cylinder, by adjusting the pressure of the cylinder in a certain predetermined area, the discs in different areas can have different rolling forces , so as to realize the pressing requirements of different areas when the material is transported or pasted. [0003] At present, the air supply area of ​​the cylinder is generally fixed, and the air supply range cannot be adjusted. If the type of material changes, because the rolling range cannot be changed, it cannot meet the needs of the material type change. The only way to reduce the use requirements or increase the partition However, increasing the number of partitions will increase a large number of pneumatic cont...

Problems solved by technology

[0003] At present, the air supply area of ​​the cylinder is generally fixed, and the air supply range cannot be adjusted. If the material type changes, because the rolling range cannot be changed, it cannot meet the needs of the material type change, and the use requirements can only be reduced or by adding partitions. However, increasing the number of partitions will increase a large number of pneumatic control valves, which will make the air circuit connection of the tire building machine complicated and difficult to troubleshoot
