A glass wool product quality on-line monitoring device

Abstract

The invention discloses an on-line glass wool product quality monitoring device, comprising a support, wherein roll shafts are installed between the side walls of two ends of the support, belts for conveying glass wool are arranged on the roll shafts, and a measuring mechanism is installed on the support and between the belts at two ends; the measuring mechanism comprises a rectangular frame, a support frame arranged above the rectangular frame and a cylinder for connecting the rectangular frame with the support frame; a plane displacement sensor extending inwards is respectively fixed at two ends of each side of the rectangular frame, a longitudinal support frame is fixed above the support frame and on the other side of the rectangular frame, and two thickness measuring displacement sensors extending to the rectangular frame are fixed on the longitudinal support frame at interval; a baffle is arranged inside each edge of the rectangular frame, the baffles are movably connected with the rectangular frame via guide rods, and the baffles are also connected with the cylinder and the plane displacement sensors. The device is suitable for detecting glass wool on a production line on line, is high in detection speed and precision, and can discover problems in time and pick rejected products out.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to an online monitoring device for the quality of glass wool finished products. Background technique [0002] Glass wool belongs to a category of glass fiber. It is a kind of artificial inorganic fiber. It uses natural ore such as quartz sand, limestone, and dolomite as the main raw material, and is melted into glass with some chemical raw materials such as soda ash and borax. The external force blowing method throws it into flocculent fine fibers, and the fibers are three-dimensionally intersected and intertwined with each other. Glass wool products are mainly installed in the interior walls of high-end buildings, ceilings, iron ducts or bellows for heat insulation, or used in studios, machine rooms, etc. for sound absorption and noise reduction, and have broad application prospects. . [0003] The size and quality of glass wool are the main factors affecting its fire and heat in...

AI Technical Summary

Problems solved by technology

In the process of glass wool production, factors such as changes in power voltage, unstable air pressure during natural gas transportation, unstable composition, uneven raw material delivery, and uneven mixing and stirring may have a greater impact on the quality of the formed fibers.

During the process of cutting glass wool into blocks, factors such as equipment vibration and aging are likely to cause problems such as irregular shape and large size error of the finished glass wool

The product inspection of glass wool is mainly carried out by visual inspection and random inspection. This inspection method has the following defects: once the product has quality problems, it cannot be detected by visual inspection or human negligence will cause a large number of losses.

[0004] At present, conventional measurement techniques such as grating distance measurement and laser distance measurement are usually used to measure the size of glass wool products. Due to the soft and rough surface of glass wool, these conventional measurement techniques will have large measurement errors.
