Abstract

The invention discloses a detecting device for the shrinkage temperature of leather based on imaging technology. The detecting device comprises a lifting platform; a motor is arranged on the lifting platform and connected with stirring blades via a center shaft; the lifting platform is further provided with a heater and a temperature sensor; the stirring blades, the heater and the temperature sensor all extend into a heating cup arranged below the lifting platform; and the stirring blades are located above the heater. According to the invention, the process of effective shrinkage deformation of the leather due to heating in a medium is recorded through visual pictures, and temperature at the moment of shrinkage is acquired via the temperature sensor. The detection device provided by the invention overcomes the problems of nonuniform temperature of a thermal medium, low sensitivity of a Hall sensor and perforation of a leather sample.

Description

technical field [0001] The invention belongs to the technical field of leather temperature detection and relates to a leather shrinkage temperature detection device based on imaging technology. Background technique [0002] Shrinkage temperature is an important physical parameter test item of leather. Specifically, it refers to the ambient temperature corresponding to the moment when the leather sample begins to shrink and deform under the influence of damp heat during the continuous and uniform heating process. , so it belongs to the inherent characteristics of leather itself. By accurately detecting its shrinkage temperature, it will directly reflect the kneading condition and heat-humidity stability of the leather, provide data support for the determination of chemical materials and environmental conditions in the kneading process, and provide guidance for further processing and production of leather products or use selection , so it is of great practical value to accura...
