Scroll-test paper machine dry-net run offset corrector

Abstract

The present invention relates to the technical field of correction equipment for dry nets of paper machines, and provides a roll detection correction device for dry nets of paper machines, which includes a support frame, a corrector valve and a roll detection device. The corrector valve is fixed on the support frame. A corrector valve shaft is arranged in the corrector valve, and the corrector valve shaft is fixedly connected with the rolling detection device. The inner side of the fixed outer frame is rotated with a plurality of rotating rollers, the fixed outer frame is provided with a sliding guide buffer assembly, and the rotating rollers are covered with wear-resistant ceramic sleeves. The rolling detection paper machine dry wire deviation corrector adopts a sliding wear-resistant ceramic sleeve structure, which has a large friction working area, low relative wear of the wear-resistant ceramic sleeve, stable response sensitivity, and long working life. Real-time detection of the deviation of the machine dryer web, so as to meet the high-speed operation requirements of the paper machine.

Description

technical field [0001] The invention belongs to the technical field of deviation correcting equipment for a dry net of a paper machine, in particular to a deviation corrector for a dry net of a paper machine for rolling detection. Background technique [0002] In recent years, with the rapid development of the paper industry and the continuous increase in output, the operating speed of the paper machine has also been continuously increased, and higher requirements have been put forward for the deviation corrector of the dry wire of the rolling detection paper machine, including Adjust the response sensitivity and adjust the movement sensitivity to ensure that the dryer roller runs at high speed without stopping the paper and the wire, so as to ensure the normal operation of the paper machine. [0003] At present, most of the corrector valves of the roller detection paper machine dry wire deviation corrector use the detection baffle as the detection part for detecting the dev...

Problems solved by technology

[0004] Under the adjustment of the correction mechanism, the operation of the drying net is relatively stable during the working process, and the friction surface between the edge of the drying net and the detection baffle also moves up and down in a small range on the smooth surface of the detection baffle, and the working area of ​​the detection baffle is also reduced. Being limited to the above range, as the detection time increases, the friction part on the smooth surface of the detection baffle gradually wears out, and the pits appearing from the wear increase the friction between the edge of the drying screen and the detection baffle, which is easy The tearing of the dryer web will reduce the service life of the detection baffle and reduce the response sensitivity of the corrector valve, which will also affect the adjustment and movement sensitivity of the pneumatic correction mechanism. For the dryer web running at high speed, it is easy to cause paper breakage The occurrence of network disconnection makes it difficult to meet the needs of high-speed operation of the paper machine
