Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking machine technology, specifically to a papermaking machine wire straightening device. Background Technology
[0002] The paper machine dryer is an important component of the paper machine, mainly used for paper forming and dewatering. The dryer's function is to remove water from the pulp as the paper passes through, allowing the paper to reach a certain degree of dryness.
[0003] In the prior art, patent document CN221421527U discloses a paper machine wire misalignment corrector, comprising two supports, each support consisting of two legs and a crossbeam. The crossbeam is fixedly installed between the tops of the two legs, and a rotating shaft is rotatably installed between the two ends of the two crossbeams, with a support roller fixedly installed on the rotating shaft. This utility model relates to the technical field of paper machine wire misalignment correction. This paper machine wire misalignment corrector reduces the need for numerous sensors to monitor the wire, thus saving monitoring costs. During adjustment, it corrects wire misalignment and wire tension simultaneously. When the tension changes after wire misalignment, an air pump drives the correction of wire tension and misalignment position. Furthermore, monitoring can be directly observed using a pressure gauge, reducing correction and maintenance costs.
[0004] To address the issue that existing technologies typically use pneumatic calibration methods, which increase maintenance and operating costs, existing technologies employ direct observation via a barometer during monitoring, thus reducing calibration and maintenance costs. However, this approach still presents challenges, such as the inconvenience of testing the calibration tension and drying the dry net during use, thereby reducing the practicality of the calibration device.
