[0024] The guide portion 21 includes a U-shaped guide plate 211, an upper connecting portion 212, and a lower connecting portion 213. The U-shaped guide plate 211 is mounted on the front end of the guide and positioning portion body 23 (the end near the reinforcing strip inlet portion) via the upper connecting portion 212 and the lower connecting portion 213. A reinforcing strip guide groove 26 for the reinforcing strip to pass through is formed between the outer wall of the U-shaped guide plate and the inner wall of the guide and positioning portion body. The inner wall of the guide and positioning portion body 23 has an arcuate transition, so that the reinforcing strip guide groove 26 has an arcuate cross-section. The arcuate inner wall of the U-shaped guide plate forms a shoe opening guide groove 24 with an arcuate transition for the shoe upper and shoe opening to pass through. One end of the U-shaped guide plate 211 is connected to the reinforcing strip inlet portion 1, and the other end of the U-shaped guide plate 211 extends to the positioning portion 22, so that the outlet end of the guide groove is located at the inlet end of the positioning portion. When installing the reinforcing belt, the reinforcing belt extends along the outer wall of the U-shaped roll plate into the reinforcing belt guide groove 26 of the arc surface, moves along the reinforcing belt guide groove 26, and is then led out from the reinforcing belt guide groove outlet end 261 to the positioning portion 22.
[0025] The positioning portion 22 includes an upper stopper 221 and a lower stopper 222, symmetrically positioned at the rear end of the guide positioning portion body 23 (near the end of the needle positioning portion).

The front ends of the upper and lower stopper are inclined at a slope 223, and the rear ends of the upper and lower stopper are horizontally disposed, so that the inclined surfaces of the upper and lower stopper form the entrance to the trumpet-shaped positioning slot 251. The front ends of the inclined surfaces of the upper and lower stopper are located at the exits of the reinforcing band guide slot and the shoe opening guide slot 24. When the reinforcing band exits the reinforcing band guide slot, its bent ends extend along the inclined surfaces of the upper and lower stopper blocks to the rear end 252 of the positioning slot, where they move toward the needle positioning portion.
[0026] The needle positioning part 3 includes a needle support plate 31 and a needle positioning guide plate 32.

The inner side of the connecting block has an arc-shaped transition. The upper end surface of the needle support plate has at least one groove 36, and a transmission mechanism 37 is arranged in the groove. The transmission mechanism is located below the needle channel. The transmission mechanism 37 is composed of at least one roller, and the roller is connected to the motor through a transmission shaft (the roller transmission mechanism is a prior art and is no longer specifically indicated in the drawings). The transmission mechanism drives the stitched shoe opening to move outward. As shown Figure 5As shown, a presser foot 38 can be provided at the intersection of the needle positioning portion 3 and the reinforcing band guide positioning portion 2. The presser foot 38 is mounted on the lower end surface of the needle positioning guide plate 32 via a torsion spring, and presses against the needle support plate 31. The reinforcing band wraps around the shoe upper and shoe opening, passes through the positioning groove 25, and reaches the needle positioning groove. The presser foot 38 presses the upper end of the reinforcing band, and the needle sews the reinforcing band to the shoe opening through the needle channel 34.
[0027] The workflow of the aforementioned shoe opening reinforcement band introduction auxiliary device is as follows: 1) The auxiliary device body is mounted on the sewing machine, above the sewing machine needle and needle channel 34. 2) The reinforcement band enters the reinforcement band introduction portion 1 through the S-shaped guide rod 4 from the reinforcement band guide entrance end 15. From the reinforcement band introduction portion, it moves into the reinforcement band guide groove 26 of the guide portion. The reinforcement band is bent in the reinforcement band guide groove 26 and exits at the reinforcement band guide groove exit end 261. The upper and lower ends of the reinforcement band extend along the inclined surfaces of the upper and lower stop blocks to the rear end 252 of the positioning groove and the needle positioning groove 35 (the rear end 252 of the positioning groove and the needle positioning groove 35 have the same cross-sectional dimensions), folding the reinforcement band in half. 3) The shoe upper and shoe opening are inserted into the shoe opening guide groove 24, with the shoe opening end resting against the curved inner wall of the U-shaped guide plate and moving along the shoe opening guide groove 24, entering the positioning groove 25 through the entrance of the trumpet-shaped positioning groove 251. Among them, the shoe opening is pressed against the curved inner wall of the U-shaped guide plate to achieve precise positioning of the shoe opening sewing position, eliminating the need for manual control and improving efficiency. 4) In the positioning groove, the bend of the shoe opening and the reinforcing belt is pressed against the inner wall of the positioning groove, so that the reinforcing belt is folded and bent to wrap around the inside and outside of the shoe opening. The width of the reinforcing belt on both sides of the shoe opening is precisely controlled to ensure that the reinforcing belts on both sides are evenly folded at the shoe opening, while also precisely controlling the sewing position of the shoe opening and the reinforcing belt. At the same time, the height of the positioning groove is only enough for the reinforcing belt to pass through after wrapping around the shoe opening, which plays a pressing role and improves flatness. 5) The reinforcing belt and shoe opening arranged in the positioning guide groove are transferred to the needle positioning groove 35. The needle sews the reinforcing belt to the shoe opening through the needle channel 34, and drives the sewn shoe opening to be transferred outward through the transmission mechanism 37.
