Figure 4The rubber band clamp 4 is provided with a second feeding channel 4211, and the rubber band clamp 4 comprises a second bottom plate 41 and a second plate 42 connected with the second bottom plate 41, and a connecting portion 43 is formed at the connection position of the second bottom plate 41 and the second plate 42. The second plate 42 is provided with a first adjusting assembly and a second adjusting assembly. The first adjusting assembly can adjust the width of the second feeding channel 4211 to adapt to rubber bands with different widths, such as rubber bands with a width of 6 mm, 8 mm or 10 mm. The second adjusting assembly can adjust the height of a pressing plate 4221 to adjust the tightness of the rubber band during conveying.

[0039] Specifically, the first adjusting assembly 421 comprises a fixed rod 4212, a first adjusting piece 4213 and a third fixing piece 4214. The first adjusting piece 4213 is fixed on the second plate 42 through the third fixing piece 4214. In the embodiment, the third fixing piece 4214 is also a screw. The first adjusting piece 4213 comprises an adjusting plate 42131 and a second connecting plate 42132. The end of the fixed rod 4212 is fixed on a fixed plate 423 on the second plate 42. The second connecting plate 42132 is sleeved on the rod body of the fixed rod 4212 and can slide on the rod body, so that the second feeding channel 4211 is formed between the fixed plate 423, the second connecting plate 42132 and the rod body. The adjusting plate 42131 comprises a second limiting channel. The connecting column (not labeled in the figure) of the third fixing piece 4214 abuts against the first end of the second limiting channel (not labeled in the figure). When the third fixing piece 4214 is not fastened, the connecting column can slide in the two ends of the second limiting channel, so that the adjusting plate 42131 can move relative to the second plate 42, and the second connecting plate 42132 can slide on the rod body, and then the width of the second feeding channel 4211 can be adjusted to adapt to rubber bands with different widths.

[0040] Specifically, the second adjusting assembly 422 comprises a pressing plate 4221, a blocking plate 4222, a spring 4223 and a screw assembly. The pressing plate 4221 and the blocking plate 4222 are arranged on the upper and lower surfaces of the second plate 42 respectively. The rubber band passes through the second feeding channel 4211 from below the pressing plate 4221. The screw assembly comprises a first screw 4224 and a plurality of nuts. The spring 4223 is sleeved on the screw rod of the first screw 4224. The upper end of the spring 4223 abuts against one of the nuts, and the lower end of the spring 4223 abuts against the pressing plate 4221. The lower end of the screw rod passes through the hole of the pressing plate 4221, the hole of the second plate 42 and the hole of the blocking plate 4222 in sequence and is then fixed by the nuts. The blocking handle 42221 is connected to the blocking plate 4222 which extends upward. The third connecting plate 42211 is connected to the pressing plate 4221 which extends downward. The lower part of the third connecting plate 42211 has a notch which abuts against the blocking handle 42221.

[0041] When the elastic band needs to be tightened, adjust the nut at the top of the spring 4223 downwards, so that the spring 4223 contracts. The spring 4223 exerts a downward force on the pressure plate 4221, which blocks the upward force exerted by the handle 42221 on the pressure plate 4221. The elastic band will become tighter, and vice versa.

[0042] Specifically, the second base plate 41 is provided with a second fixing hole 411. In this embodiment, the second base plate 41 is fixed on the platform 6 parallel to the bed surface 5 of the machine by inserting a second fastener (not shown in the figure) into the second fixing hole 411.

[0043] During operation, the elastic band is first adjusted to the appropriate tension using the elastic band clamp 4, and the width of the second feed channel 4211 is adjusted accordingly. The elastic band then exits through the second feed channel 4211, enters the first channel 113, exits from below the first channel 113, and enters the first feed channel 13. The elastic band then exits from below the second channel 122 upwards, reverses direction, and enters the space between the toothed needle plate 3 and the presser foot 2 (the route of the elastic band is...). Figure 4 (Center route 7), then the edge of the cut piece is folded from the second end 121 of the first plate 12. The width of the folded edge is slightly wider than the width of the elastic band. The elastic band is wrapped in the middle of the folded cut piece and the upper cut piece. Then the cut piece and the elastic band enter between the toothed needle plate 3 and the presser foot 2 along the right side of the stop 32 and start sewing. In this way, the double-line sewing of the edge-feeding elastic band and the inward fold can be completed simultaneously, improving efficiency and maintaining the elasticity of the product and ensuring stable quality.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
