An intelligent detection system for color difference of continuous pad dyeing machine

Abstract

The invention discloses an intelligent detection system for continuous pad dyeing vehicle color differences. The intelligent detection system comprises a near-infrared moisture tester, two air pressure control valves and a control processor. The near-infrared moisture tester is fixedly installed at the position of a wet cloth outlet of a pad dyeing vehicle. The measurement end of the near-infrared moisture tester faces the surface of a fabric. The output end of the near-infrared moisture tester is connected with the input end of the control processor. The two air pressure control valves are correspondingly installed on compressed air input pipes at the two ends of a roller of the pad dyeing vehicle and are in control connection with the output end of the control processor. Compared with the prior art, the near-infrared moisture meter is used as the collecting end of the intelligent detection system for the color differences, so that the detection precision of the detection system is higher; meanwhile, the near-infrared moisture tester is installed at the position of the wet cloth outlet of the pad dyeing vehicle, and the number of defected fabrics caused by color differences is decreased.

Description

technical field [0001] The invention relates to a detection system, in particular to an intelligent detection system for the color difference of cloth on a pad dyeing machine. Background technique [0002] Dyeing is the process of making the whole textile have a certain color by means of a physical or chemical structure between the dye and the fiber, or chemically producing pigments on the fiber; it is a process of dyeing at a certain temperature, time, pH value and required dyeing auxiliaries, etc. carried out under the conditions. Fabric dyeing methods are mainly divided into exhaust dyeing and pad dyeing, wherein exhaust dyeing is a method in which the fabric is dipped in the dye solution, and the dye is gradually dyed on the fabric. It is suitable for small batch dyeing of many varieties. Rope dyeing and jigger dyeing belong to this category; pad dyeing is to dip the fabric in the dye solution first, and then make the fabric pass through the rollers of the pad dyeing ma...

Problems solved by technology

Although this intelligent detection method of image recognition overcomes the defects of the naked eye detection method, the camera is easily affected by factors such as the vibration of the pad dyeing machine and the intensity of external light when it is in use, resulting in blurred imaging and poor contrast. In addition, there is inevitably steam and dust in the environment of the printing and dyeing workshop. This steam and dust are very easy to attach to the camera lens, which will also cause the problem of blurred imaging of the camera.
