Shrinking function of the shrinking machine

The pre-shrinking function of the pre-shrinking machine :

The main structure is rubber blanket, rubber blanket pressure roller, rubber blanket tension roller, rubber blanket pressure roller, rubber blanket edge spray device, rubber blanket pressure roller, rubber blanket tension adjustment roller, pressure roller drive motor.

Its function is: the rubber blanket made of natural rubber through special treatment, with its excellent and durable elasticity and durability, becomes an excellent carrier for fabric shrinkage; the function of the pressure roller is to compress the rubber blanket, under certain conditions, the rubber The degree of shrinkage of the blanket is proportional to the degree of compression. The principle of determining the pressure should first meet the shrinkage requirements of the fabric, and secondly protect the rubber blanket to make its performance stable and extend its service life; the function of the tension roller is to make the rubber blanket produce a certain tension, so that the rubber The blanket has good shrinkage performance under certain pressure conditions; the function of the pressure roller is to press off the cooling residual water on the rubber blanket to avoid water spots.

The function of spraying at the edge of the blanket is to adjust the temperature difference during the operation of the rubber blanket, so that the performance of the rubber blanket is stable and the service life is extended. Because the width of the rubber blanket is larger than the width of the processed fabric, there will be parts on both sides of the rubber blanket that directly contact with the fabric. The steam-passing pressure roller is in contact, and most of the middle of the rubber blanket is in contact with the steam-passing pressure roller through a layer of processed fabric, so that there is a temperature difference between the sides of the rubber blanket. Set to adjust; the role of the bearing roller is to form the tension and pressure of the rubber blanket with the tension roller and the pressure roller respectively, and at the same time provide the precondition for shrinkage of the fabric: one of heat and heat, the bearing roller The steam pressure is generally a fixed parameter; the tension regulating roller is controlled by a small motor, whose function is to adjust the tension change caused by the overfeeding of the felt, and the small motor will automatically adjust the position of the tension roller according to the force of the tension roller to make the fabric run Normal; the driving motor of the bearing roller provides the running power for the rubber blanket.
