This utility model relates to the field of yarn feeder technology, and discloses a guide roller assembly and a yarn feeder for a high-speed, multi-path yarn feeder. The guide roller assembly includes a bearing B, a bearing A, a roller, a mandrel, an elastic washer, and fixing screws. Bearing B is a floating bearing. An O-ring is added to the mandrel at the location of the floating bearing B. By changing the depth of the groove of the O-ring and the matching of the O-ring wire diameter, suitable friction can be obtained, stabilizing the static state of the inner ring of the floating bearing B, avoiding wear between the inner ring of bearing B and the mandrel, and ensuring that the bearing is always in a normal working state. This guide roller assembly has a simple structure and stable improvement effect.

This invention discloses an online detection method for the working status of a descaling nozzle in a rolling mill, relating to the field of hot rolling technology. Its main purpose is to avoid product waste, reduce production costs, and improve detection efficiency. The main technical solution of this invention is as follows: The detection method includes: placing a calibration plate coated with a detection coating at a designated position above the work rolls of the rolling mill; activating the descaling nozzle of the rolling mill and continuing for a first preset time to allow descaling water to wash over the detection coating, forming watermarks; acquiring characteristic parameters of the watermarks, including morphological and positional parameters; and determining the working status of the descaling nozzle based on a comparison of the characteristic parameters with preset parameter thresholds.

This invention relates to an air outlet temperature field measuring device, specifically a method for measuring the air temperature field at the outlet of a braking resistor device. A temperature measuring plate with ventilation openings, made of 304 stainless steel, is installed at the air outlet of the forced-air-cooled braking resistor device. During operation, the plate is heated by the cooling air, resulting in an oxide film on its surface. Since the oxide film thickness is related to the cooling air temperature and affects the interference colors, the color distribution of the oxide film produced after the temperature measuring plate is oxidized by the high temperature of the cooling air can be used to deduce the temperature distribution of the cooling air at the outlet, i.e., the air outlet temperature field. The materials are inexpensive and readily available; the densely spaced openings on the temperature measuring plate minimize the impact on the cooling airflow, ensuring that the operating conditions during temperature measurement closely approximate the normal operating state of the braking resistor device.
