The guide post bolt 5322 guides the pressing operation of the spring 5323, and prevents the leg plate 5324 from shaking left and right to affect the pressing stability of the pressing fixing leg 5213/pressing moving leg 532.

Before the device works, the distance between the front side sewing mechanism 2 and the back side sewing mechanism 3 is roughly adjusted in advance through the electric screw rod 31 according to the width of the towel cloth, so that the distance between the front side sewing mechanism 2 and the back side sewing mechanism 3 can basically adapt to the width of the towel cloth. And then according to the width of the towel cloth, the first folding screw rod 423 and the second folding screw rod 524 are started, and the distance between the front side pressing dragging component 421 and the back side pressing dragging component 422 and the distance between the front side pressing fixing component 521 and the back side pressing fixing component 522 are properly adjusted, so that the towel cloth can be stably and accurately pressed on the table top 11 and cannot interfere with each other during working. The towel cloth transferred in the previous process (i.e. cutting and labeling) is pressed on the table board 11 by the pre-sewing transfer mechanism 6 on the front side and the back side and is dragged towards the direction of the sewing transfer mechanism 4, when the towel cloth reaches the sewing transfer mechanism 4, the front side pressing transfer component 421 and the back side pressing transfer component 422 of the sewing transfer mechanism 4 respectively press the left side and the right side of the towel cloth, and at the moment, the pre-sewing transfer mechanism 6 is reset and loosens the towel cloth. The sewing transfer cylinder 41 of the sewing transfer mechanism 4 drives the pressing and dragging unit to move horizontally in the direction of the overedger 21, and the overedger 21 overedges the towel cloth. The pressing dragging unit can move left and right to drag a plurality of pieces of towel cloth at the same time, and in the process, the pressing dragging unit and the pressing fixing unit 52 of the continuous sewing auxiliary mechanism 5 alternately press the plurality of pieces of towel cloth, so that the towel cloth is guaranteed to be pressed all the time. The pressing and pulling unit 53 of the continuous sewing auxiliary mechanism 5 performs a pressing operation simultaneously with the pressing and fixing unit 52, and the pressing and pulling unit 53 presses one piece of terry cloth closest to the discharge side and pulls the terry cloth to the discharge side by the drive of the discharge screw 51.
