Description

Technical Field

[0001] This utility model belongs to the technical field of anti-deviation devices, and specifically relates to an anti-deviation device for papermaking machines. Background Technology

[0002] The paper machine is the core equipment in the modern papermaking industry, which can convert pulp into paper.

[0003] Currently, to prevent paper from deviating during transport, anti-deviation mechanisms are installed on paper conveyor lines to calibrate the direction of paper transport. Traditional anti-deviation mechanisms have a simple structure, with a basic principle of a swinging roller. During paper transport, the roller swings at the bottom of the paper based on the deviation position detected by the detection equipment, thereby adjusting the transport direction of the paper to achieve the purpose of preventing paper deviation. Although it can achieve the function of correction, there are still some problems in its use. For example, the roller structure of traditional anti-deviation mechanisms is fixed and the length cannot be adjusted. However, the width of paper produced by different manufacturers is different, and the roller length cannot be adjusted, resulting in poor applicability. At the same time, the traditional roller and roller support are connected by a bearing seat. When the roller wears out after long-term use and needs to be replaced, the bearing seat needs to be removed from the ears of the roller support. The bearing seat is usually designed inside the ears of the roller support and is fixed by multiple bolts, making disassembly extremely troublesome. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deviation device for papermaking machines, which has the advantages of being suitable for correcting deviations of paper of different widths and being easy to replace.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-deviation device for a paper machine, comprising a base, a connecting seat on the top of the base, mounting seats symmetrically arranged on the top of the connecting seat, a correction roller on the top of the mounting seat, adjusting grooves symmetrically opened on the top of the connecting seat, a bidirectional threaded rod rotatably connected between the two adjusting grooves, a connecting block fixedly connected to the mounting seat being threaded on the surface of the bidirectional threaded rod, limiting seats being hinged to the top of the ears at both ends of the mounting seat, semi-circular slots being opened on the top of the ears at both ends of the mounting seat and the bottom of the limiting seats, a bearing seat being engaged between the two semi-circular slots, a shaft being fixedly sleeved at the center of the correction roller, and the bearing seat being fixedly sleeved with the shaft.

[0006] The above technical solution is as follows: This utility model has two mounting seats designed on the connecting seat, and each mounting seat is equipped with a correction roller. The distance between the two mounting seats can be adjusted by rotating the bidirectional threaded rod under the action of the connecting block. The distance adjustment between the two correction rollers makes it suitable for correcting paper of different widths, thus improving applicability. A limit seat is set on the top of the mounting seat ear. Semi-circular slots for engaging the bearing seat are opened on both the mounting seat ear and the limit seat. When the correction roller needs to be replaced, it is only necessary to unscrew the limit nut to separate the limit seat from the mounting seat ear. The correction roller then drives the bearing seat out of the semi-circular slot under the action of the shaft, without the need to remove multiple bolts, thus improving the convenience of disassembly.

[0007] The present invention is further configured such that a rotating column is rotatably connected to the top of the base, and the rotating column is fixedly connected to the connecting seat.

[0008] By adopting the above technical solution, the connecting seat can be rotated and limited, allowing it to swing around the rotating column as its axis.

[0009] The present invention is further configured such that a swing frame is fixedly connected to the connecting seat, a support frame is fixedly connected to the front of the base, and a cylinder is hinged between the support frame and the swing frame.

[0010] The above technical solution limits and fixes the cylinder, and facilitates the swinging of the connecting seat when the cylinder's extension and retraction end extends and retracts.

[0011] The present invention is further configured such that support blocks are symmetrically fixedly connected to the front side of the base.

[0012] The above technical solution involves installing and fixing the base to improve its stability.

[0013] The present invention is further configured such that semi-circular limiting posts are fixedly connected to the ears at both ends of the mounting base and the limiting base, and a limiting nut is threaded between the two semi-circular limiting posts.

[0014] The above technical solution facilitates the fixing of the limiting seat and the mounting seat's ears together.

[0015] The present invention is further configured such that sliders are mounted on both the front and back sides of the connecting block, and a sliding groove is provided inside the adjusting groove to slide and connect with the sliders.

[0016] The above technical solution involves sliding and limiting the connecting block.

[0017] The present invention is further configured such that one end of the bidirectional threaded rod extends through to the outside of the connecting seat and is fixedly sleeved with a rotating disk.

[0018] The above technical solution facilitates the rotation of the bidirectional threaded rod.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model has two mounting seats designed on the connecting seat, and each mounting seat is equipped with a correction roller. The distance between the two mounting seats can be adjusted by rotating the bidirectional threaded rod under the action of the connecting block. The distance between the two correction rollers can be adjusted to make it suitable for correcting paper of different widths, thus improving its applicability.

[0021] 2. This utility model has a limiting seat set on the top of the mounting ear. Both the mounting ear and the limiting seat have semi-circular slots for engaging the bearing seat. When the straightening roller needs to be replaced, simply unscrew the limiting nut to separate the limiting seat from the mounting ear. This allows the straightening roller to pull the bearing seat out of the semi-circular slot under the action of the shaft, eliminating the need to remove multiple bolts and improving the convenience of disassembly.
