In a preferred embodiment, the fully automated back-punch binding and cutting line 100 may include a plurality of sewing apparatuses 20 arranged at intervals. Wherein the sewing needle 231 of the sewing machine 23 of each sewing machine 20 is arranged in a staggered position. As can be seen from FIG. 2, multiple rows and columns of braces 201 need to be sewn to the paper strip 200 for subsequent use in conjunction with the undergarment. In the invention, the back buckles 201 in a plurality of rows and a plurality of columns can be sewn and fixed at one time through a plurality of sewing devices 20 arranged at intervals and the sewing needles 231 on the sewing machine devices 23 of the sewing devices 20 are arranged in a staggered mode, so that the binding efficiency of the back buckles 201 can be further improved.

In a preferred embodiment shown in fig. 3 and 4, the material passage 22 may include a back-buckle passage 221 and a paper belt passage 222, and the back-buckle passage 221 may include: a first channel shell 223 fixed on the sewing platform 21, wherein a vertical channel is formed in the first channel shell 223, and a discharge hole facing the sewing platform 21 and a feed hole communicated with the discharge hole of the material sieving device 10 are formed on the vertical channel; and peg boards 224 disposed within the vertical channel along the vertical channel. Wherein, be formed with the clearance with back dunk shape assorted between the interior perisporium of vertical passageway and the side surface of link plate 224, the back dunk can be through the clearance in proper order along vertical passageway slip. In this embodiment, the back-fastening channel 221 is connected to the discharge port of the sieving device 10. During the use, the clearance that forms between the interior perisporium of vertical passageway and the side surface of link plate 224 for the material need enter into vertical passageway according to the uniform form, and this uniform form is the horizontality of being convenient for its to sew up promptly, and the back dunk 201 material of U-shaped is horizontal puts into vertical passageway in proper order promptly. Therefore, the cross section of the gap should also be U-shaped (as shown in connection with FIG. 4), and the U-shaped cross section should be fittingly capable of being placed into the back button 201. Through the arrangement, no matter the paper tape 200 falls horizontally, the production requirement is more convenient through the movement of the material pushing mechanism 24 or the binding of the sewing machine equipment 23, and the binding quality is ensured.

Preferably, returning to fig. 3, the tape path 222 may include a first tape path 222 at the feeding side of the sewing device 20, the first tape path 222 being configured as a second path housing 225 fixed to the sewing table 21, a horizontal path being formed in the second path housing 225, and an entrance and exit for the passing of the tape 200 being formed in the horizontal path. With this arrangement, paper strap 200 can be made more planar by having paper strap 200 enter the binding work area through first paper strap passage 222, thereby avoiding stitching problems.

In a preferred embodiment, the tape path 222 may further include a second tape path 222 (not shown) located on the discharge side of the sewing device 20 and communicating with the cutting device 30, the second tape path 222 being configured as a third path housing fixed to the sewing platform 21, a horizontal path being formed in the third path housing, an inlet and an outlet being formed on the horizontal path for the tape to pass through, and the outlet being connected to the cutting device 30. With this arrangement, the tape can be made more flat by passing it through second tape passageway 222 into cutting apparatus 30, thereby avoiding the cutting problem.

In a preferred embodiment, the material path 22 may further include a distance adjusting mechanism (not shown) fixed to the sewing table 21, and a driving end of the distance adjusting mechanism is connected to the paper tape path 222 for adjusting a moving distance of the paper tape path 222 in a width direction. As can be seen from FIG. 2, multiple rows and columns of braces 201 need to be sewn to the paper strip 200 for subsequent use in conjunction with the undergarment. In the present invention, the distance adjustment mechanism can adjust the moving distance of the paper tape channel 222 along the width, and by this arrangement, the binding position of the sewing machine 23 can be changed by adjusting the preset distance of the paper tape 200, so that the requirement of sewing and fixing the back-up 201 in multiple rows and multiple columns on the paper tape 200 can be satisfied.
