Description

technical field [0001] The present invention relates to an integrated dyeing and drying production line, more specifically, to a digitally controlled precision controlled ultrasonic dyeing and microwave drying production line. Background technique [0002] The dyeing technology that has been used in the leather industry for a long time is drum dyeing. Drum dyeing is intermittent batch production. Each batch needs to place the leather in the drum for 4-6 hours of dyeing. This dyeing process is not only inefficient, but also labor intensive. It is strong and usually produces a lot of sewage; for this reason, the inventor of the present application has developed a fast leather dyeing machine (Chinese patent ZL200620064114.3, announcement number: CN200971422Y), which solves the problem by using ultrasonic technology. The leather industry has used drum dyeing technology for many years to realize rapid dyeing of leather. However, the dyed leather needs to be manually collected fo...

[0002] The dyeing technology that has been used in the leather industry for a long time is drum dyeing. Drum dyeing is intermittent batch production. Each batch needs to place the leather in the drum for 4-6 hours of dyeing. This dyeing process is not only inefficient, but also labor intensive. It is strong and usually produces a lot of sewage; for this reason, the inventor of the present application has developed a fast leather dyeing machine (Chinese patent ZL200620064114.3, announcement number: CN200971422Y), which solves the problem by using ultrasonic technology. The drum dyeing technology that has been used in the leather industry for many years has realized the rapid dyeing of leather

However, the dyed leather needs to be manually collected for subsequent processing such as extrusion, drying or drying. The traditional drying process is mostly natural drying or thermal drying. Natural drying is greatly affected by the weather and takes up a lot of space; Thermal drying usually adopts far-infrared heating or steam heating technology. Although the efficiency is improved, the softness of the leather is not good, the leather shrinks greatly, the yield of leather is low, and the energy consumption is high, and the temperature of the processing environment is high (the drying temperature of leather Usually around 95°C), the working conditions of workers are difficult; in view of this, the inventor of this application has developed a microwave leather dryer (Chinese patent ZL200920056111.9, announcement number: CN201517108U) in order to solve the drying technology after leather dyeing , to solve the technical problem of fast drying of leather, the drying quality is better than that of infrared heating and steam heating, and the energy consumption is relatively low; in addition, on the basis of the above-mentioned technology, the inventor of the present application combined the ultrasonic leather dyeing machine with Combining microwave drying technology, a microwave drying production line for ultrasonic dyeing of leather was developed (patent number ZL201120540847.0, announcement number CN202390656U), which solved the technical problems of rapid dyeing and drying of leather

However, in the actual use of the above-mentioned production line, the drying quality is unstable, the auxiliary time and labor intensity between the dyeing and drying processes are large, and the production efficiency is low. , Drying new technology, promote the technical progress of the leather industry
