Referring to fig. 4, the first driving motor 1210 is a servo motor.

The working principle is as follows:

the fabric before and after dyeing is dried and shaped by the drying box 2, the moving speed and temperature of the fabric after the fabric enters the drying box 2 are adjusted by controlling the power of the hot air blower module 3 and the running speed of the winding module 11, so as to realize different temperature and speed requirements of pre-shaping and post-shaping, the fabric passes through the feeding module 8 and then sequentially passes through the soaking mechanism 13 and the draining mechanism 15, the fabric with uneven surface moisture is uniformly pretreated by the soaking mechanism 13 and the draining mechanism 15, so that the fabric is in uniform humidity before entering the drying box 2, the drying effect of the whole piece of fabric is highly uniform, the drying effect is improved, when the fabric in the step D and the step F just begins to be filled into the drying box 2, the front end of the fabric is automatically driven to move in the longer drying box 2 by running the feeding mechanism 12, therefore, the fabric is matched and tensioned with the first conveying rollers 6, and labor is saved.

When the feeding mechanism 12 is operated, two workers can hold two corners of a fabric, the fabric is stretched into the slot 125 at the inlet end of the drying box 2, the first rotating rod 128 drives the plurality of fixed claws 129 to rotate for a certain angle by operating the first driving motor 1210, so that when the fixed claws 129 contact the bottom of the inner wall of the slot 125, the fabric is clamped, then the folding type electric track 121 is operated, the moving end of the folding type track 121 is initially positioned at one side close to the inlet of the drying box 2, the two moving blocks 122 at the moving end of the folding type electric track 121 synchronously drive the strip-shaped plate 123 to perform folding type movement, and further drive the fabric to perform folding type movement in the drying box 2, due to the self gravity of the fabric, the fabric pulled into the drying box 2 can automatically contact with the first conveying roller 6 at the top of the drying box 2, and further enable the fabric to sequentially tension with the plurality of first conveying rollers 6, the strip-shaped plate 123 finally moves to the outlet of the drying box 2 and then passes through the leveling mechanism 16; when the soaking mechanism 13 is operated, clean water is arranged in the soaking bucket 132, after the fabric enters the soaking bucket 132 from the feeding module 8, the fabric sequentially passes through the three second conveying rollers 133, the fabric is soaked by the clean water in the process of passing through the three second conveying rollers 133, the second rotating rod 134 drives the fan blades 135 to rotate by operating the second driving motor 136, so that the flow speed of water flow in the soaking bucket 132 is increased, the soaking speed of the fabric is increased, the water in the soaking bucket 132 can be periodically replaced by switching the electromagnetic valve 138, and the soaked fabric enters the draining mechanism 15; when the draining mechanism 15 is operated, the fourth rotating rod 158 is pulled by the two extrusion springs 156 to pull the third rotating rod 155, so that the connecting block 154 and the two swing arms 152 are pulled, and due to the self-gravity of the movable roller 153 and the downward elastic pulling of the swing arms 152, when the fabric passes between the movable roller 153 and the first extrusion roller 159, a large amount of moisture in the fabric is extruded and dropped into the water storage tank 10, so that a large amount of moisture in the fabric passing through the draining mechanism 15 is discharged, and the fabric integrally keeps uniform moisture content; when the leveling mechanism 16 is operated, the third driving motor 165 is operated, so that the driving pulley 166 drives the driven pulley 167 to rotate, and the first gear 163 is driven to rotate, and since the first gear 163 is meshed with the second gear 164, the first gear 163 and the second gear 164 simultaneously drive the two second squeezing rollers 162 to rotate oppositely, and the fabric is squeezed when passing through the two second squeezing rollers 162, so that the fabric surface is leveled.

Before packaging, the stretching degree of the underwear fabric of the embodiment is tested according to the stretching degree test method of LTD03, and the opening degree of the material is tested to reach more than 110%.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
