The rubber band sewing and connecting device is provided with the rubber band positioning plate 120, the rubber band positioning plate 120 is provided with a first rubber band positioning area 1211, a second rubber band positioning area 1212 and a sewing and connecting area 1213, when the rubber band sewing and connecting device is in actual use, the first connecting section 310 of the rubber band is arranged in the first rubber band positioning area 1211 and the sewing and connecting area 1213, the second connecting section 320 of the rubber band is arranged in the second rubber band positioning area 1212 and the sewing and connecting area 1213, and the first end and the second end opposite to the rubber band are aligned and abutted, so that the rubber band is fixed, and the plane ports at the two ends of the rubber band are abutted and fixed in position. At this time, the first docking section 310 and the second docking section 320 are then sewn together by the sewing mechanism 200 with the planar ports in the docked state. Therefore, the rubber band positioning mechanism 100 can avoid the mode of overlapping and connecting in the traditional technology, does not need an operator to assist in fixing the rubber band, can improve the sewing and connecting efficiency of the rubber band, and can eliminate the potential safety hazard in the overlapping and sewing and connecting process.

Further, another embodiment of the invention also provides a rubber band sewing and connecting method, which adopts the rubber band sewing and connecting device according to the embodiment to sew and connect the rubber band to be connected. The method comprises the steps of fixing the rubber band to be connected and sewing the rubber band to be connected.

Specifically, the step of fixing the rubber band to be connected comprises the following steps: placing a first connection section 310 of the rubber band to be connected into a first rubber band positioning zone 1211 and a sewing connection zone 1213, wherein the first connection section 310 comprises a first end of the rubber band to be connected, the first end is located in the sewing connection zone 1213, and a first fixing piece is adopted to fix part of the first connection section 310 of the first rubber band positioning zone 1211; and, the second section 320 of plugging into of rubber band that will wait to plug into is arranged in second rubber band location district 1212 and sewing district 1213 of plugging into, and second section 320 of plugging into includes the second end relative with the first end, and the second end also is arranged in sewing district 1213 of plugging into, makes second end and first end align and butt, adopts the fixed section 320 of plugging into of the part of second rubber band location district 1212 of arranging into of second mounting.

Fig. 4 shows a specific placement of the rubber band in the rubber band positioning hole 121. Wherein, the rubber band of waiting to plug into is rectangular form rubber band, and rectangular form rubber band has first end and second end, and the sewing is all arranged in with the second end of rubber band and is plugged into district 1213, and aligns the butt between the first end of rubber band and the second end. Wherein the first end is aligned with the second end means that there is no misalignment between the first end and the second end. The rubber band positioning mechanism 100 in the above embodiment mainly functions to align the first end and the second end of the rubber band to abut, and if the rubber band is manually fixed, the rubber band is difficult to align the abutting completely, and the finally obtained rubber band ring is not enough in connection strength and is easy to crack.

Wherein, the rubber band has first section 310 and the second section 320 of plugging into, and first section 310 of plugging into is including first end and by first end to one section rubber band that the rubber band middle part extended, and the second section 320 of plugging into is including the second end and by one section rubber band that the second end extends to the rubber band middle part. The first docking section 310 is comprised of two parts, one part being disposed in the sewing docking zone 1213 and the other part being disposed in the first elastic positioning zone 1211. The second docking section 320 is also made up of two parts, one part placed in the sewing docking zone 1213 and the other part placed in the second elastic positioning zone 1212. Specifically, the first docking section 310 and the second docking section 320 are located on a straight line, that is, an angle of 180 ° is formed between the first docking section 310 and the second docking section 320.

The first connecting section 310 of the rubber band to be connected completely fills the first rubber band positioning zone 1211 in the length direction, and the second connecting section 320 of the rubber band to be connected completely fills the second rubber band positioning zone 1212 in the length direction.

The rubber band to be connected is also provided with a part located outside the rubber band positioning hole 121, the part outside the rubber band positioning hole 121 is connected to the first connection section 310 and the second connection section 320 at the same time, and therefore after the step of fixing the rubber band to be connected, the whole rubber band is annular. Since the elastic positioning hole 121 has the first elastic positioning zone 1211, the sewing connection zone 1213, and the second elastic positioning zone 1212 in specific shapes, the first connection section 310 and the second connection section 320 of the elastic can be aligned, abutted, and fixed.

After the rubber band to be connected is placed in the rubber band positioning hole 121, the sewing needle in the sewing mechanism 200 can be controlled to drive the sewing thread to alternately pass through the first connection section 310 and the second connection section 320 along the zigzag sewing line 400. The zigzag sewing line 400 can be seen in the detailed schematic diagram shown in fig. 4. In the traditional technology, when the rubber bands are stacked, a flat car is generally adopted to sew the stacked rubber bands together through a straight sewing line. In the embodiment, a flat-connection rubber band is proposed, and in order to ensure the quality of the rubber band joint, the first connection section 310 and the second connection section 320 are connected in a sewing mode through a Z-shaped sewing line 400. If other sewing lines 400 are adopted, the first connection section 310 is easily separated from the second connection section 320, which results in poor rubber band connection.
