Description

Technical Field

[0001] This utility model belongs to the field of vacuum roller technology, specifically relating to a reciprocating moving part for a vacuum roller and its stable support device. Background Technology

[0002] Vacuum couch rolls are most widely used in the papermaking industry. They are an important component of papermaking machinery, located at the end of the wet end, where the paper sheet is lifted off the forming wire.

[0003] Vacuum Cow Rollers, due to their large size and heavy weight, often require auxiliary support structures during operation. Current support systems are mostly in the form of rollers, placed below one side of the vacuum Cow Roller, with the outer wall of the roller designed to be tightly tangential to the roller. In this layout, the roller remains fixed and rotates with the vacuum Cow Roller. However, this design inevitably leads to severe wear on the outer wall of the vacuum Cow Roller, requiring frequent maintenance measures such as welding or electroplating to repair damage. However, the high temperatures generated during welding induce thermal stress, which is difficult to completely eliminate; as for electroplating, its limited coating thickness makes it prone to peeling. These factors combined significantly reduce the effective service life of the vacuum Cow Roller. Utility Model Content

[0004] The purpose of this utility model is to provide a reciprocating moving part for a vacuum roller and its stable support device, thereby solving the above-mentioned problems existing in the prior art.

[0005] Technical solution: A reciprocating moving component for a vacuum roller includes two sets of parallel mounting bases. Each mounting base is a frame with a hollow center. A drive motor is mounted at one end of one of the mounting bases, and the output end of the drive motor is connected to a transmission assembly. Two sets of drive assemblies are mounted on the top of the mounting base, located at both ends of the transmission assembly. The drive assemblies are connected to the transmission assembly, and the transmission assembly drives the two sets of drive assemblies to rotate in opposite directions. A moving component is slidably mounted on the top surface of the mounting base along its length. The moving component is engaged with the drive assembly, causing the moving components to move closer to or further away from each other.

Two sets of slide rails are provided at both ends of the top of the housing along the length of the housing. The transverse central axes of the slide rails overlap each other. Support blocks are respectively installed at both ends of the top of the reciprocating assembly. The support blocks pass through the slide rails.

A plurality of balls are circumferentially installed on the outer wall of the roller, and the balls are in contact with the body surface of the vacuum roller.

[0011] Beneficial effects: This utility model relates to a reciprocating moving component for a vacuum roller and its stable support device. Driven by a drive motor, the drive assembly rotates, and with the cooperation of the transmission assembly, the moving assembly reciprocates on the top surface of the mounting base.

The transmission assembly 3 drives the two sets of drive assemblies 4 to rotate in opposite directions. A moving assembly 5 is slidably mounted on the top surface of the mounting base 1 along its length. The moving assembly 5 is engaged with the drive assembly 4, causing the moving assembly 5 to move closer or further away from each other, simplifying the operation process and avoiding the possibility of human error.

[0025] In a further embodiment, the transmission assembly 3 includes a transmission shaft 31, which is installed at the output end of the drive motor 2.

A placement plate 53 is installed on the top surface of the trapezoidal sliding block 52. The placement plate 53 is integrally formed with the trapezoidal sliding block 52. A rack 54 is installed on the bottom surface of the placement plate 53 near the spur gear 41. The rack 54 is operably meshed with the sector gear 42. The trapezoidal slider can be driven to reciprocate within the trapezoidal receiving cavity through the mutual cooperation of the sector gear 42 and the rack 54.
