Description

Anti-deviation fixed short shaft structure for connecting synchronous shaft of reeling part of paper machine

Technical Field

The utility model belongs to the technical field of the paper machine, a prevent fixed minor axis structure partially for connection of paper machine batch portion synchronizing shaft is related to.

Background

The reeling section of the paper machine is also called a roll winder or a drum winder. It is composed of paper winding roller, paper winding cylinder, machine frame and roller-changing device. Installed at the end of a paper machine for winding the produced paper web into rolls for storage and further processing. Surface winders are widely used reeling devices which rotate by friction between a reeling drum and a reeling cylinder and wind the paper web onto a reel-up. When the paper roll on the paper roll reaches the specified diameter, the winding part automatically acts to replace the paper roll: that is, the empty winding roller starts winding while the wound paper roll is pushed out, and the process is called roll change, and the roll change has the characteristic of periodicity and uninterrupted. In order to realize continuous roll changing, the roll changing mechanism needs to ensure that the two sides of the paper rolling roll rise and fall synchronously and have consistent height, and therefore, the roll changing mechanism is provided with a set of synchronous shafts which are connected with the two ends and ensure the action consistency.

The frame is used as the base in current synchronizing shaft both ends, through the assembly of minor axis and joint bearing, realizes rotatoryly, nevertheless appears wearing and tearing because of the structural design of minor axis easily, and the minor axis produces the displacement easily in axial direction after wearing and tearing, can't realize axial fixity. When the synchronous shaft rotates, the short shaft has a little displacement, the displacement of the short shaft directly causes the abrasion of the matching hole of the base, the size deviation caused by the abrasion greatly influences the synchronous function, and the reel replacement of the reeling part fails. Meanwhile, the short shaft is directly assembled with the rack, the rack is damaged due to abrasion of the short shaft, the rack is damaged and repaired with great difficulty, and meanwhile, the joint bearing is easy to shift in axial position, so that the service life of the joint bearing is influenced.

In order to overcome the disadvantages of the prior art, various solutions have been proposed through continuous research, such as that a chinese patent discloses a winding section having a double auxiliary unit [ application No.: 98804358.0], including the reel-up in a paper machine, in which paper is wound onto a winding roll to form a paper spool, the reel-up having two bracket members with bracket rails to support the winding roll; there is also an auxiliary device having first and second auxiliary units for receiving new winding rolls, each auxiliary unit including a first auxiliary member and a second auxiliary member, each of which is disposed on a support member. According to the invention both auxiliary members of each auxiliary unit are arranged outside the carrier member. However, the short-shaft connecting structure of the synchronous shaft and the knuckle bearing are still easy to have axial position deviation in the working process, so that the defects of high abrasion and short service life are caused.
