[0025] A first bidirectional lead screw 19 is provided above the first guide rail 10. A first mounting plate 20 and a second mounting plate 21 are respectively provided at both ends of the first mounting base plate 11. The two ends of the first bidirectional lead screw 19 are rotatably connected to the first mounting plate 20 and the second mounting plate 21, respectively. A first movable block 19a and a second movable block 19b that move in opposite directions are provided on the first bidirectional lead screw 19.

The other end of the first bidirectional lead screw 19 is equipped with a first retaining ring 23, which is located outside the first mounting plate 20. Turning the first handwheel 22 causes the first movable block 19a and the second movable block 19b on the first bidirectional lead screw 19 to move towards each other, thereby causing the first limiting plate 4a and the second limiting plate 4b to move towards each other along the first guide rail 10 to accommodate materials of different sizes. A first limiting block 24 is provided between the second mounting plate 21 and the first handwheel 22. After the corresponding position is adjusted, the first limiting block 24 is fixed on the first bidirectional lead screw 19 to prevent loosening.

[0027] The second hopper 5 has the same structure as the first hopper 4. The second hopper 5 includes a third limiting plate 5a and a fourth limiting plate 5b, which are slidably mounted on the second guide rail 12. The second guide rail 12 has multiple second sliders.

[0029] A second handwheel 27 is provided at one end of the second bidirectional lead screw, located on the outer side of the fourth mounting plate. A second retaining ring is provided at the other end of the second bidirectional lead screw, located on the outer side of the third mounting plate. Turning the second handwheel 27 causes the third and fourth movable blocks on the second bidirectional lead screw to move towards each other, thereby causing the third limiting plate 5a and the fourth limiting plate 5b to move towards each other along the second guide rail 12 to accommodate materials of different sizes. A second limiting block is provided between the fourth mounting plate and the second handwheel 27. After the corresponding positions are adjusted, the second limiting block is fixed on the second bidirectional lead screw to prevent loosening.

[0030] The lifting drive assembly includes a lifting module 28 and a lifting drive motor 29. The lifting module 28 is mounted on the loading base 3 via a module mounting column 30. The lifting drive motor 29 is connected to the lifting module 28 via a coupling 31. The lifting module 28 is connected to the first material support plate 6 and the second material support plate 7 via a material support lifting frame 32. The lifting module 28 is equipped with a lifting moving plate 33, which is connected to the rear end of the material support lifting frame 32 via a material support connecting plate 34. The first material support plate 6 and the second material support plate 7 are mounted on the front end of the material support lifting frame 32. The lifting drive motor 29 drives the first material support plate 6 and the second material support plate 7 to move up and down synchronously.

[0031] The rear end of the material lifting frame 32 is equipped with a linear bearing 35, and a guide rod 36 is installed inside the linear bearing 35. The bottom of the guide rod 36 is fixed on the loading base 3. Since the two sets of lifting drive components are symmetrically installed on the loading base 3, the two sets of lifting modules 28 are fixed together, and the tops of the guide rods 36 in the two sets of lifting drive components are connected by a shaft connecting plate 37.

[0032] The top of the first hopper 4 and the top of the second hopper 5 are equipped with photoelectric sensors 38 for detecting whether the material on the shoe tongue is being fed. When the photoelectric sensor 38 detects that the top of the first hopper 4 and the second hopper 5 is short of material, the lifting module 28 drives the first material support plate 6 and the second material support plate 7 to rise synchronously, moving the material in the second-to-top layer of the first hopper 4 and the second hopper 5 to the top layer.

[0033] The rotary drive assembly includes a central control rotary platform 39 and a rotary drive motor 40. The platform base 39a of the central control rotary platform 39 is fixed on the mounting bracket 41. The rotating table 39b of the central control rotary platform 39 is fixedly connected to the loading base 3, and the drive shaft of the rotary drive motor 40 is rotatably connected to the input end of the central control rotary platform 39. The central control rotary platform 39 typically uses a gear transmission system to achieve rotary motion. The gears are connected to the power source through the transmission shaft, and the rotation of the rotary platform is achieved through the meshing of the gears. Therefore, the rotary drive motor 40 drives the rotary platform to rotate, thereby driving the loading base 3 to rotate.

[0034] Sensors 42 are installed on the rotating platform 39b of the central control rotating platform 39 to detect information such as the position, speed and status of the rotating platform. Sensors 42 are connected to the control system to realize precise control and monitoring of the rotating platform.

[0035] The lifting drive assembly drives the first material support plate 6 and the second material support plate 7 to feed materials upward. When a set of shoe tongue material bins is short of material, the rotation drive assembly drives the feeding base 3 to rotate. The positions of the two sets of shoe tongue material bins on the feeding base 3 are interchanged, which will not affect the normal operation of the production line. At the same time, it is convenient to release materials and improves work efficiency.

[0036] The material handling device includes a robotic arm 52 and a material handling main board 43 installed at the execution end of the robotic arm 52. The robotic arm 52 is fixedly connected to the material handling main board 43 through a material handling connector 44. The material handling main board 43 is fixedly mounted with a first needle-punching component 45 and a second needle-punching component 46. The material handling direction of the first needle-punching component 45 is perpendicular to the material handling direction of the second needle-punching component 46.

[0037] like Figure 6 As shown, the first needle-punching assembly 45 is horizontally mounted inside the material-picking main board 43 via the first material-picking mounting plate 47, and the second needle-punching assembly 46 is vertically mounted inside the material-picking main board 43 via the second material-picking mounting plate 48.

[0038] The main material picking board 43 is provided with a corresponding secondary material picking board 49, which is fixedly connected to the first material picking mounting plate 47 and the second material picking mounting plate 48. A first cover plate 50 and a second cover plate 51 are provided between the main material picking board 43 and the secondary material picking board 49. The first cover plate 50 is located at the bottom of the main material picking board 43, and the second cover plate 51 is located at the front end of the main material picking board 43.

[0039] In this embodiment, both the first needle-punching component 45 and the second needle-punching component 46 adopt a material gripping device for sewing fabric as described in patent application document No. 202021217566.7. In this embodiment, there are two sets of the first needle-punching component 45 and the second needle-punching component 46. The number of needle-punching components can be adjusted appropriately according to different sizes of materials, and there can be one or more needle-punching components.

[0040] The robotic arm 52 moves the material-picking mainboard 43 to the storage device. The first needle-punching component 45 moves above the first material bin 4. The robotic arm 52 moves the first cover plate 50 downward to press the material, and the first needle-punching component 45 picks up the upper piece of the shoe tongue. The robotic arm 52 rotates and moves the material-picking mainboard 43. The second needle-punching component 46 moves above the second material bin 5. The robotic arm 52 moves the second cover plate 51 downward to press the material, and the second needle-punching component 46 picks up the lower piece of the shoe tongue. Subsequently, the robotic arm 52 moves the material-picking mainboard 43 to the feeding area 1a of the sewing workbench 1. The upper and lower pieces of the shoe tongue are placed in the feeding area 1a in sequence, realizing the material picking steps of the upper and lower pieces of the shoe tongue. Then, the camera 2 above the feeding area 1a collects data on the position of the upper and lower pieces of the shoe tongue. The control system controls the robotic arm 52 to perform stacking and correction steps on the upper and lower pieces of the shoe tongue.

[0041] The feeding device includes a pressing drive cylinder that drives the pressing plate to move up and down, a pushing drive cylinder that drives the pressing plate to move back and forth, and a rodless cylinder that drives the pressing plate to move horizontally between the feeding area 1a and the sewing area 1b. The feeding device moves the stacked upper and lower pieces of the shoe tongue to the sewing area 1b. A sewing machine head is located above the sewing area 1b to sew the edges of the upper and lower pieces of the shoe tongue together.

[0042] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
