Abstract

The present application belongs to the technical field of textile dyeing, and discloses a cloth dyeing and finishing temperature synchronous adjusting mechanical device, which comprises a dyeing pool, a dyeing groove is arranged in the middle of the dyeing pool, an air inlet pipe is fixedly connected to one side of the dyeing pool, and an air outlet pipe is fixedly connected to the other side of the dyeing pool. Through the cooperation of the heat expansion temperature sensing bag, capillary pipes, sleeves, plug rods, valve cores and sliding groove boxes, the temperature sensing liquid is driven to expand and contract with heat or cold by using the temperature change of the dyeing liquid itself, the plug rod drives the valve core to move linearly through the pressure transmission of the capillary pipes, the opening degree of the valve core is proportional to the temperature deviation, the lower the temperature is, the more the valve core rises, and the greater the flow of the heating medium is, the closer the temperature is to the set value, the smaller the opening degree of the valve core is, the proportional regulation of the heating power and the temperature error is realized, the temperature control precision is improved without the electric control system, the problem that the electronic components are prone to failure in a high temperature and high humidity environment is effectively avoided, the response lag of the electric control regulation is eliminated, and the dyeing uniformity is improved.
