[0017] Beneficial Effects

[0018] The utility model provides a clamping structure and a shoe upper hole punching device thereof, which has the following beneficial effects:

[0019] 1. A clamping structure and a shoe hole punching device for a shoe upper, by setting two sets of limit components and through the vertical displacement of the mounting plate, when the mounting plate descends, the two rollers gradually contact the fabric, and the reaction force given to the rollers by the fabric causes the rollers to push the sliding body to slide in the sliding channel and squeeze the first elastic member. The first elastic member takes a spring as an example, and the two ends of the spring are fixedly connected to the top of the sliding body and the top surface of the flip body respectively. At the same time, since the two flip bodies are distributed in an outward-facing manner, the vertical thrust given by the sliding body to the flip body generates a horizontal component force, thereby pushing the flip body to flip in a direction away from the other flip body. The rollers roll on the surface of the fabric, and the two rollers give the fabric a reverse pulling force to flatten the fabric, while pressing the fabric downward to limit the fabric, thereby ensuring that the fabric between the two rollers remains flat, thereby facilitating punching and suppressing the generation of wrinkles. At the same time, the rollers can roll on the surface of the fabric, which can ensure that the rollers will not separate from the fabric as the punching position changes, and always have a clamping and limiting effect.

[0020] 2. This clamping structure and its upper shoe hole punching equipment, by setting a pressure block, as the flipping body flips and the sliding body slides, when the mounting plate gradually approaches the fabric, the pressure block can flip to contact the fabric to achieve hard contact with the fabric, and has two fixing methods: elastic limitation of the fabric and hard contact limitation, which is convenient for adjustment according to the softness and deformation degree of the fabric.

[0021] 3. This clamping structure and its upper shoe hole punching equipment, by setting a center block, uses the trapezoidal center block to limit the two flip bodies. When the mounting plate is away from the fabric, the flip bodies will flip toward the center block. The center block can reduce the flipping of the flip bodies to a vertical state, which is convenient for the roller to limit the fabric during the next clamping process, thereby ensuring stability during repeated use.

[0028] A clamping structure and a shoe upper hole punching device thereof, such as Figure 1 and Figure 2 As shown, including:

[0029] The mounting plate 10 is a plate-like structure for mounting. Specifically, a U-shaped arch frame is fixedly mounted on the top surface of the mounting plate 10, and the arch frame is provided with mounting holes;

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the limit assembly is arranged at the bottom of the mounting plate 10 for pressing the fabric. Two sets of limit assemblies are symmetrically arranged at the bottom of the mounting plate 10. The limit assembly includes a flip body 11, a sliding body 12 and a roller 13. The flip body 11 is rotatably connected to the mounting plate 10, the sliding body 12 is elastically connected to the flip body 11, and the roller 13 is rotatably connected to the sliding body 12. Both flip bodies 11 are elastically connected to the mounting plate 10. The two flip bodies 11 can move away from or approach each other. The two rollers 13 can roll on the surface of the fabric to press and flatten the fabric. The flip body 11 A sliding channel 14 is provided at the bottom, the sliding body 12 is slidably connected to the sliding channel 14, a first elastic member is provided in the sliding channel 14 for pushing the sliding body 12 to slide, an integrally formed protrusion is provided on the top surface of the flip body 11, an ear plate is fixedly connected to the bottom of the mounting plate 10, the protrusion is rotatably connected to the ear plate, the sliding channel 14 forms a notch adapted to the sliding body 12, an elastic member is provided on the top of the sliding body 12, the elastic member includes a spring but is not limited to a spring, a rectangular notch is provided at the bottom of the sliding body 12, a roller shaft 13 is located in the notch, and both ends of the roller shaft 13 The two rollers 13 are rotatably connected to the inner wall surfaces on both sides of the sliding body 12. In this solution, two sets of limit assemblies are set. Through the vertical displacement of the mounting plate 10, when the mounting plate 10 descends, the two rollers 13 gradually contact the fabric. The reaction force exerted by the fabric on the rollers 13 causes the rollers 13 to push the sliding body 12 to slide in the sliding channel 14 and squeeze the first elastic member. The first elastic member is a spring, for example. The two ends of the spring are fixedly connected to the top of the sliding body 12 and the inner top surface of the flip body 11, respectively. At the same time, since the two flip bodies 11 are distributed in an outward-octave manner, the sliding body 1 The vertical thrust of the flip body 11 generates a horizontal component force, thereby pushing the flip body 11 to flip in the direction away from the other flip body 11. The roller 13 rolls on the surface of the fabric. The two rollers 13 pull the fabric in the opposite direction to flatten it. At the same time, the fabric is pressed down to limit the position, ensuring that the fabric between the two rollers 13 remains flat, thereby facilitating punching and suppressing the generation of wrinkles. At the same time, the roller 13 can roll on the surface of the fabric, ensuring that the roller 13 will not separate from the fabric as the punching position changes, and always has a pressing and limiting effect.

[0031] like Figure 4As shown, the limiting assembly also includes a pressing block 15, which is fixedly connected to the sliding body 12. The pressing block 15 can contact the fabric and press the fabric tightly. The pressing block 15 forms a trapezoidal block structure, and the inclined surface of the pressing block 15 faces downward. The walls of the two sliding bodies 12 that are close to each other are fixed with the same pressing block 15. By setting the pressing block 15, as the flipping body 11 flips and the sliding body 12 slides, when the mounting plate 10 gradually approaches the fabric, the pressing block 15 can flip to contact the fabric to achieve hard contact with the fabric. It has two fixing methods: elastic limiting of the fabric and hard contact limiting, which is convenient for adjustment according to the softness and deformation degree of the fabric.

[0032] like Figure 2 and Figure 5 As shown, a center block 20 is fixedly connected to the bottom of the mounting plate 10, and the center block 20 forms an isosceles trapezoidal block. The waists on both sides of the center block 20 are respectively facing the two flip bodies 11. The two flip bodies 11 can approach the center block 20 and form an outward-facing structure. The two waists of the center block 20 are fixedly connected to the same second elastic member. The second elastic member includes a tension spring but is not limited to a tension spring. The other end of the tension spring is fixedly connected to the flip body 11. As a supplement to the above scheme, by setting the center block 20, the trapezoidal center block 20 is used to limit the two flip bodies 11. When the mounting plate 10 is away from the fabric, the flip body 11 will flip toward the center block 20. The center block 20 can reduce the flipping of the flip body 11 to a vertical state, which is convenient for the roller 13 to limit the fabric during the next clamping process, thereby ensuring stability for repeated use.

[0033] Not shown in the figure, a shoe upper shoe hole punching device includes a frame, an electric cylinder is fixedly installed on the frame, a punching head is installed on the output shaft of the electric cylinder, and the output shaft of the electric cylinder is provided with all the above-mentioned clamping structures, and the mounting plate 10 is fixedly installed with the output shaft of the electric cylinder by fasteners. A laser punching head can be used through the punching head. The laser punching head includes an excitation generator and a laser head. This is an existing well-known technology and will not be elaborated here. A window for avoiding the laser head is opened on the wall of the mounting plate 10, and the window is located between the two flip bodies 11. The above-mentioned clamping structure is provided, which has a good limiting effect on the fabric, and can also flatten the fabric during the limiting process to inhibit the formation of wrinkles.

[0034] The working principle of the utility model is as follows: a double-axis truss is installed on the frame, and an electric cylinder is installed on the output end of the truss. The mounting plate 10 is pushed downward by the electric cylinder. The electric cylinder can be a servo electric cylinder. Through the vertical displacement of the mounting plate 10, when the mounting plate 10 descends, the two rollers 13 gradually contact the fabric. The reaction force exerted by the fabric on the rollers 13 causes the rollers 13 to push the sliding body 12 to slide in the sliding channel 14 and squeeze the first elastic member. The first elastic member is a spring, for example. The two ends of the spring are fixedly connected to the top of the sliding body 12 and the inner top surface of the flip body 11 respectively. At the same time, since the two flip bodies 11 are distributed in an outward-octave manner, the sliding body 12 exerts a vertical thrust on the flip body 11 to generate water The component force in the horizontal direction then pushes the flip body 11 to flip in the direction away from the other flip body 11, and the roller 13 rolls on the surface of the fabric. The two rollers 13 apply reverse pulling force to the fabric to flatten the fabric, and at the same time press the fabric downward to limit the position, ensuring that the fabric between the two rollers 13 remains flat. The trapezoidal center block 20 is used to limit the two flip bodies 11. When the mounting plate 10 is away from the fabric, the flip body 11 will flip toward the center block 20. The center block 20 can reduce the flipping of the flip body 11 to a vertical state, which is convenient for the roller 13 to limit the fabric during the next clamping process. This is suitable for children's shoes, and of course it can also be used for bevel punching in the production process of adult shoes.
