Dry net deviation detector

Abstract

The invention discloses a dry net deviation detector. The dry net deviation detector comprises a mounting seat, a base, a support arm, a slide arm, a branch arm, a detecting seat and a winding reel. The base is mounted in the mounting seat. The support arm is mounted at the center of the top of the base. A first insertion groove is formed in one side of the support arm. A gear box is mounted at the top end of the support arm. First threaded rods are mounted at the top of the base and on the periphery of the support arm. The top ends of the first threaded rods penetrate the slide arm, and driven wheels located in the gear box are mounted at the top ends of the first threaded rods. A rotating shaft is mounted at the internal center of the gear box. The dry net deviation detector has the advantages that dry net deviation interference signals generated by limited vibration sources can be effectively prevented, and accordingly, safety and production stability of dry nets are ensured; height and length adjustment of detected portions is rapidly completed, local adjustment after mounting of the detector is facilitated, re-disassembly and re-assembly are not needed, and the length of a guide line is adjusted conveniently during overall adjustment of the detector.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a device for detecting deviation of a dry web. Background technique [0002] With the development of science and technology, the performance of papermaking machinery has been continuously improved, and the production speed has been greatly improved. The dryer wire in the drying section of the paper machine transmits the paper web at high speed on the guide roller. The slight deviation of the guide roller or the shrinkage of the dryer wire will cause the lateral swing of the dryer wire on the guide roller. Under the premise that the dryer wire correction device cannot correct , if the transmission is not stopped in time, there will be a risk of the dry network being torn and broken, resulting in unnecessary downtime and damage to spare parts; the traditional dry network deviation system is a single deviation detection, when the detected dry network deviation signal, It will s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for detecting the deviation of the dryer web. In order to overcome the unavoidable vibration of various guide rollers and other mechanical devices during the high-speed operation of the paper machine, the dryer web deviation alarm often occurs. Due to the influence of the vibration source, the detection signal of the device may cause false alarms, and the deviation alarm signal is linked with the transmission, so it is easy to cause some abnormal situations; and when the detection device is installed for the deviation of the dry network, the Different positions need to adjust the height and length of the detection device. The existing adjustment method is to change the installation position of the detection device to achieve adjustment, but the technical problem of adjusting the installation position is complicated
