Description

Technical Field

[0001] The utility model relates to the technical field of tensioning devices, and more specifically, to a novel horizontal felt tensioning device. Background Art

[0002] The press section of a paper machine is a crucial component of the papermaking process. Its primary function is to remove as much moisture from the wet paper web as possible, evenly, and stably through mechanical compression. The press section significantly increases the dryness of the wet paper web, playing a crucial role in increasing paper machine output and reducing production costs.

[0003] During the pressing process, the felt on the upper and lower sides of the paper needs to be tightened. After the upper and lower rollers are closed, they are loaded by the hydraulic cylinder. During the operation of the paper machine, the paper between the felts is squeezed to achieve the purpose of dehydrating the paper.

[0004] The tensioning of the felt in the press section is generally carried out by a tensioning roller, but the existing tensioning device lacks a monitoring structure. When the tension on the felt is too great, it is easy to cause damage to the felt. In particular, the tensioning roller is the first point where the force is exerted when the felt is tightened. Therefore, it is particularly important to monitor the contact area between the felt and the tensioning roller. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a novel horizontal felt tensioning device, aiming to solve the problems raised in the background technology.

At the same time, the connecting pipe is sleeved on the outer surface of the mounting shaft, and a transmission wheel is fixedly sleeved on the outer surface of the connecting pipe.

[0015] Compared with the prior art, the present invention provides a novel horizontal felt tensioning device, which has the following beneficial effects:

[0016] 1. In this solution, the mounting seat is installed at a suitable position in the press section of the paper machine. The guide roller between the fixed plates is used to guide the felt. The threaded rod inside the body groove rotates to facilitate the movement of the trapezoidal seat, thereby driving the movement of the mounting plate, the mounting shaft and the tensioning roller, thereby achieving tensioning of the felt. The camera on the monitoring board can monitor the felt on the outer surface of one side of the tensioning roller, and the displacement distance of the tensioning roller when the felt is tightened can be monitored by the displacement sensor.

[0017] 2. In this solution, the motor is adjusted to facilitate the rotation of the rotating shaft, and the rotating shaft can conveniently drive the driving wheel to rotate. Since the driving wheel and the transmission wheel are connected by a transmission belt, it is convenient to drive the transmission wheel to rotate. The rotation of the transmission wheel can conveniently drive the connecting pipe to rotate.

At the same time, the connecting pipe 5 is sleeved on the outer surface of the mounting shaft 404, and a transmission wheel 6 is fixedly sleeved on the outer surface of the connecting pipe 5.

[0029] In this embodiment, the transmission wheel 6 rotates to facilitate the rotation of the connecting pipe 5. Since the two connecting plates 406 are fixedly connected through the monitoring plate 407, it is convenient to drive the two connecting plates 406 to rotate, thereby facilitating the angle adjustment of the monitoring plate 407.

The felt body 12 is part of the felt of the press section of the paper machine, and the felt body 12 is wound between the tensioning roller 405 and the guide roller 2. When tensioning is required, the drive motor 11 is started to drive the threaded rod 401 to rotate, driving the trapezoidal seat 402 to slide inside the trapezoidal groove, driving the mounting plate 403, the mounting shaft 404 and the tensioning roller 405 to move away from the guide roller 2, tightening the felt body 12, and monitoring the monitoring plate 407. The displacement sensor 409 on the upper portion monitors the displacement distance of the tensioning roller 405. When it is necessary to monitor the fitting portion of the felt cloth body 12 and the tensioning roller 405, the camera 408 and the adjustment motor 10 are driven.
