Pneumatic circulation drying system of soft drying machine

Abstract

The invention provides a pneumatic circulation drying system of a soft drying machine. The system comprises a cloth inlet, a first cloth storage box, a cloth outlet, a second cloth storage box, a cloth groove air flue, a main fan and an auxiliary fan, the cloth groove air flue is connected with the first cloth storage box and the second cloth storage box, the main fan and the auxiliary fan are communicated with the cloth groove air flue, the main fan is connected with at least one main air duct, the main air duct is connected with a main air duct reversing valve plate, the main air duct reversing valve plate is connected with a left branch main fan and a right branch main fan of the main fan, the left branch main fan and the right branch main fan are connected with the cloth groove air flue; the auxiliary fan is connected with at least one auxiliary air duct, the auxiliary air duct is connected with an auxiliary air duct reversing valve plate, the auxiliary air duct reversing valve plate is connected with a left branch auxiliary fan and the right branch auxiliary fan of the auxiliary fan, the left branch auxiliary fan and the right branch auxiliary fan are connected with the clothgroove air flue. According to the pneumatic circulation drying system, the reversible air duct structure is arranged, so that the fabric is supported by the upper hot air flow and the lower hot air inthe air duct for left and right reciprocating motion and is beating, so that the fabric can obtain a soft hand feeling, meanwhile, the fabric can obtain an ideal pre-shrinking effect in a tension-free state and a high-temperature state, in addition, due to the fact that the fabric does not rub with any object, the pilling is avoided.

Description

technical field [0001] The invention relates to the technical field of pneumatic drying of dryers, in particular to a pneumatic circulation drying system of a judo dryer. Background technique [0002] The hot air air dryer is usually used to dry fabrics such as long strips of cloth. The fabric is blown by hot air in the air duct of the dryer to obtain a certain pre-shrinking effect. The current hot air flow type dryer is provided with a fan, the fan is connected with the air duct, and the hot air is blown into the air duct. Usually, the air flow flows in one direction from the air duct inlet to the air duct outlet, or the air flows between the first air duct entrance and the second air duct. Two-way flow between the entrance and exit of the air duct. In the one-way flow structure, the fan is connected at the entrance of the air duct. The first fan and the second fan are turned on in turn. Whether it is the existing one-way flow structure or two-way flow structure, the fabri...
