[0024] The following will be combined with the embodiments of the utility model patent to clearly and completely describe the technical solutions in the embodiments of the utility model patent. Obviously, the embodiments described are only part of the embodiments of the utility model patent, not all of the embodiments. Based on the embodiments of the utility model patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model patent.

[0025] Reference Figure 1-Figure 7As shown, the present invention provides a first embodiment of a reverse-stitched synchronous reinforcing belt device, comprising a base 1, a needle mechanism 2, a reinforcing belt unwinding mechanism 3, a reinforcing belt laminating mechanism 4, a conveyor mechanism 5, and a cutting mechanism 6. The conveyor mechanism includes a front conveyor belt 51 and a rear conveyor belt 52, each mounted on the base 1. The needle mechanism 2 is positioned between the front conveyor belt 51 and the rear conveyor belt 52. The reinforcing belt laminating mechanism 4 and the cutting mechanism 6 are sequentially mounted on a housing 7 and positioned above the rear conveyor belt 52. The reinforcing belt unwinding mechanism 3 is positioned above the housing 7, wherein the housing 7 is mounted on the base 1 via a plurality of support frames 71. The reinforcing tape 11 is installed within the reinforcing tape unloading mechanism 3 and sequentially passes through two drive wheels 9 to the reinforcing tape laminating mechanism 4. The process: the shoe fabric is conveyed by the front conveyor belt 51 to the needle mechanism 2 for reverse stitching. The stitched shoe fabric is then transferred to the rear conveyor belt. The rear conveyor belt 52 drives the stitched shoe fabric to the reinforcing tape laminating mechanism 4. The rear conveyor belt 52 cooperates with the reinforcing tape laminating mechanism 4 to attach the reinforcing tape to the stitching area of the shoe fabric and transfer it to the cutting mechanism 6 for shearing, completing the reverse stitching and simultaneous reinforcing tape laminating process. This device is preferably used for reverse stitching and reinforcing tape laminating at the heel of two pieces of shoe fabric.

[0026] The needle mechanism 2 includes a machine platform 21 and a work surface 22. The work surface is disposed between the front conveyor belt 51 and the rear conveyor belt 52. The upper end surface of the work surface 22 is flush with the upper end surfaces of the front conveyor belt 51 and the rear conveyor belt 52. The machine platform is equipped with a needle 23, and the work surface 22 is located below the needle 23.

[0027] The reinforcing tape unloading mechanism 3 includes a belt reel 31 and a gluing device 32. The belt reel 31 and the gluing device 32 are mounted on a discharging frame 33. The reinforcing tape cloth roll is mounted on the belt reel, and the reinforcing tape 11 can be continuously pulled out in cooperation with the belt reel 31. The gluing device 32 includes a gluing box 321, a gluing roller 322, a gluing box 323, and a scraper 324 placed within the gluing box. An inlet 325 and an outlet 326 are symmetrically provided on both sides of the gluing box. A transmission roller 327 is provided at the inlet 325. The glue coating box 323 is equipped with a first glue roller 328 and a second glue roller 329 that cooperate with each other. The first glue roller 328 is placed in the glue coating box and contacts the glue inside the box. The second glue roller 329 is placed through the side wall of the glue coating box (i.e., part of the glue roller is located in the inner cavity of the glue coating box, and the rest of the glue roller is located outside the glue coating box). The second glue roller 329 is located between the first glue roller 328 and the glue spreading roller 322 and abuts against them. One end of the scraper 324 is fixed to the inner wall of the glue coating box, and the other end of the scraper extends to the glue spreading roller 322. The first glue roller 328 transfers the glue to the second glue roller 329, and then the second glue roller 329 transfers the glue to the glue spreading roller 322. The scraper 324 smoothly and evenly scrapes the glue on the surface of the glue spreading roller. As the reinforcing belt passes through the drive roller 327 and sequentially through the feed port 325 into the gluing box 321, the bottom of the glue roller 322 abuts against the reinforcing belt 11, and the glue is evenly applied to the reinforcing belt 11 by the glue roller 322. The glued reinforcing belt 11 then exits through the discharge port 326. Two drive wheels 9 are provided at the end of the housing 7 near the needle mechanism. The two drive wheels 9 are symmetrically positioned at the upper and lower ends of the housing. The glued reinforcing belt passes through the two drive wheels 9 and is then passed between the reinforcing belt laminating mechanism 4 and the rear conveyor belt 52. The reinforcing belt laminating mechanism 4 presses the reinforcing belt 11 toward the rear conveyor belt.

[0028] The reinforcing belt fitting mechanism 4 is composed of at least two pressing roller devices, and the pressing roller device includes a roller support 41, a first telescopic rod 42 and a pressing roller 43. The first telescopic rod 42 is installed between the roller support 41 and the pressing roller 43. A return spring 44 is sleeved on the first telescopic rod 42. With the cooperation of the return spring 44, the pressing roller 43 is always pressed in the direction of the rear conveyor belt, so as to facilitate the fitting of the reinforcing belt to the shoe fabric.

[0029] An infrared sensor 10 is positioned between the cutting mechanism 6 and the reinforcing tape applying mechanism 4. After the shoe fabric is applied by the reinforcing tape applying mechanism 4, the infrared sensor 10 monitors the shoe fabric's position and transmits a signal to the cutting mechanism 6, which activates the cutting mechanism and cuts the reinforcing tape 11 downward. Specifically, the cutting mechanism 6 comprises a base 61, a cylinder 62, and a cutter assembly 63. The base 61 is mounted on the housing 7, the cylinder 62 is mounted on the base 61, and the cutter assembly 63 is located at the bottom of the cylinder 62. The cylinder 62 is connected to a cylinder control valve via an air pipe, which is connected to an external air source and includes a signal receiving device (the connection between the cylinder and the cylinder control valve and the signal receiving device are both conventional and not shown in the accompanying drawings). When the infrared sensor 10 detects the shoe fabric, it transmits a signal to the signal receiving device, which then drives the cutter assembly 63 downward at a set time interval to cut the reinforcing tape 11. The cutting mechanism 63 comprises a cutter holder 631 and a cutter 632 mounted on the holder. The cutter holder 631 is mounted at the bottom of the cylinder 62. There is only one cutter 632, and the interval between activations of the cylinder control valve is set based on the desired length of the reinforcement tape. An infrared sensor detects when the shoe material leaves the reinforcement tape attachment mechanism and transmits a signal to the cylinder control valve, driving the cylinder to activate. The cutter descends twice to complete a set of cutting operations. The interval between the two descents is set based on the desired length of the reinforcement tape to be cut.

[0030] The housing 7 is symmetrically provided with clamping and conveying mechanisms 8 on both sides. The transmission frequencies of the front and rear conveyor belts 51, 52, and clamping and conveying mechanisms 8 are the same. Each set of clamping and conveying mechanisms 8 consists of a conveyor belt support 81 and two sets of conveyor belts. The two sets of conveyor belts are mounted on the conveyor belt support 81, and a transmission channel for the shoe fabric to pass through is formed between the two sets of conveyor belts 82. The conveyor belt includes a transmission belt 82, a driving wheel 83, a driven wheel 84, and multiple sets of transmission wheel assemblies 85. The driving wheel 83 and the driven wheel 84 are respectively arranged at the inner ends of the transmission belt 82. The driving wheel 83 is connected to the support motor 86 via a transmission shaft 831. The driven wheel 84 is mounted on the conveyor belt support 81 via a connecting shaft 841. Multiple sets of transmission wheel assemblies 85 are evenly arranged between the driving wheel 83 and the driven wheel 84. The transmission wheel assembly 85 includes a rotating wheel 851 and a pressure wheel 852. The rotating wheel is connected to the conveyor belt support 81 via a second connecting shaft 853 and can rotate along the second connecting shaft 853. The third connecting shaft 855 of the pressure wheel 852 is connected to the second connecting shaft via a second telescopic rod 856. The second telescopic rod is sleeved with a return spring 857. Preferably, there are two second telescopic rods 856, distributed at the upper and lower ends of the third connecting shaft. The pressure wheel 852 can rotate along the third connecting shaft 855. The driving wheel 83, the driven wheel 84, the pressure wheel 852 and the rotating wheel 851 all abut against the inner side of the transmission crawler 82. The pressure wheels 852 in the two sets of transmission belts press toward the transmission channel, so that the shoe material is clamped in the transmission channel and sequentially cut off from the transmission direction. The two ends of the shoe fabric are clamped by the clamping transmission mechanism 8 to prevent the shoe fabric from shifting, ensuring that the seaming points of the shoe fabric are located below the corresponding needle mechanism, reinforcement band fitting mechanism and cutting mechanism in sequence, ensuring that the seaming, reinforcement band fitting and reinforcement band cutting processes are accurately aligned and carried out smoothly.

[0031] Regarding the method of using the above-mentioned reverse-stitched synchronous reinforcement belt device, the steps are as follows:

[0032] 1) Install the reinforcing belt 8. The reinforcing belt reel is mounted on the belt reel. One end of the reinforcing belt is pulled out of the reel and passed through the drive roller 327 into the gluing device 32. The gluing roller 322 in the gluing device evenly applies glue to the reinforcing belt. The belt then passes through the gluing device and passes through the two drive wheels 9. The glued reinforcing belt 8 is then transferred between the reinforcing belt laminating mechanism 4 and the rear conveyor belt 52.

[0033] 2) Backstitch the shoe fabric. Take the two pieces of fabric that need to be stitched and clamp the ends of the two pieces away from the stitching to the clamping conveyor mechanism 8 on both sides. With the inner surface of the stitched shoe fabric facing upward, it is easy to backstitch. A staff member arranges the stitching locations of the two pieces at the upper end of the front conveyor belt and manually locates the stitching location. The front conveyor belt then assists in transferring the stitching to the needle mechanism 2, which sews the stitching joints of the shoe fabric. When needle mechanism 2 completes backstitching of the shoe fabric, the staff member repeats step 2 to backstitch the next set of shoe fabric.

[0034] 3) Reinforcement Band Lamination. The stitched shoe material is moved toward the rear conveyor belt 52 with the cooperation of the clamping conveyor mechanisms 8 on both sides. The rear conveyor belt 52 and the clamping conveyor mechanisms cooperate to transfer the stitched shoe material between the reinforcement band laminating mechanism 4 and the rear conveyor belt 52. The glue-coated reinforcement band 8 is positioned below the pressing roller 43. The seam of the shoe material is transported to the bottom of the reinforcement band via the rear conveyor belt and pressed against the seam by the pressing roller 43, completing the reinforcement band lamination.

[0035] 4) Cutting the reinforcing tape. The shoe fabric with the reinforcing tape attached to it passes through the rear conveyor 52 and the clamping conveyor mechanism 8, leaving the pressing roller device. When the infrared sensor 10 detects the position of the shoe fabric, it sends a signal to the cutting mechanism, which receives the signal and starts working, controlling the time and speed of the cutter's descent to complete the cutting of the reinforcing tape.

[0036] The above-mentioned reverse-stitching synchronous reinforcement belt device can be installed on the operating table 12 and operated by workers. At the same time, a placement frame 13 can be placed at the rear end of the operating table. After the shoe material reinforcement belt is cut, the clamping and conveying mechanism continues to convey it backward until the stitched shoe material falls into the placement frame.

[0037] Reference Figure 8As shown, the present invention provides a second embodiment of a reverse-stitching synchronous reinforcing belt device. This device is essentially the same as the first embodiment, differing in that the cutter assembly 63 comprises a cutter holder 631 and two cutters 632 adjustably mounted on the holder. The cutter holder 631 is mounted at the bottom of the cylinder 62, and the distance between the two cutters 632 is adjustable. The distance between the two cutters 632 is adjusted based on the desired length of the reinforcing belt. Specifically, a mounting slot 633 is provided at the bottom of the cutter holder 631. Two symmetrical connecting holes 634 extend through the mounting slot on either side of the cutter holder. An adjusting screw 635 passes through the connecting hole 634 and the mounting slot 633, respectively. The two cutters are connected to the adjusting screw 635 with forward and reverse threads, respectively. An adjusting handwheel 636 is fixed to the end of the adjusting screw. Turning the adjusting screw 635 drives the two cutters 632 to move in opposite or opposite directions, thereby adjusting the distance between the cutters. A positioning groove 637 is provided on the top of the placement groove, and a positioning block 638 is provided on the top of the cutter. The positioning block is inserted into the positioning groove to prevent the cutter from rotating, so that the cutter moves along the trajectory of the positioning groove.
