Technical Field

[0001] The utility model relates to the technical field of shoe upper shaping, in particular to a shoe upper heating shaping mechanism. Background Art

[0002] The upper heating and shaping mechanism is a device used to heat and shape the upper of a shoe, and usually includes heating elements, such as resistance wires, heating plates, etc., which generate heat to heat the upper. It may also be equipped with a mold or a fixed structure to ensure that the upper can be shaped according to a specific shape and requirements during the heating process, so that the upper can obtain the desired shape, curvature or other features to meet the requirements of the overall design and manufacturing process of the shoe.

[0003] Generally speaking, applying pressure will help to achieve a better shaping effect. Applying appropriate pressure can make the upper fit more closely to the mold, accelerate the shaping process and improve the accuracy and stability of shaping, so applying pressure is a common method. After searching the prior art CN218682435U, a shoe upper heating shaping mechanism is disclosed, and its structure includes a machine body, a bottom plate, a base, a cylinder, a heat shaping head, and an arc-shaped protrusion; during heat shaping, a protective layer is provided on the heat shaping head to prevent the electric heating layer from directly acting on the upper, thereby protecting the upper, and a temperature sensor and a display screen are provided to understand the temperature in real time to prevent the upper from being damaged by excessive temperature.

[0004] However, the prior art is prone to the following technical problems during the heat setting process of the shoe upper: during mold-assisted pressure heat setting, due to the lack of effective buffering function, excessive pressure is often applied, which in turn causes quality deformation or damage to the shoe upper, which seriously affects the quality and pass rate of the product, while also increasing production costs and resource waste, and reducing production efficiency, and cannot meet the needs of high-quality production.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A shoe upper heating and shaping mechanism comprises a machine body 1, a frame 2 fixedly mounted on the machine body 1, a heat-setting head 5 movably arranged on the inner side of the frame 2, and an arched punch 6 fixedly mounted on the machine body 1; a mounting plate 301 is fixedly mounted on the inner side of the frame 2, an electric cylinder 3 is fixedly mounted on the top of the mounting plate 301, an inverted U-shaped connecting frame 4 is fixedly connected to the top of the heat-setting head 5, and the output end of the electric cylinder 3 movably penetrates into the inverted U-shaped connecting frame 4 and is fixedly connected to a movable block 7, and the movable block 7 is slidably mounted in the inverted U-shaped connecting frame 4 along the vertical direction; two lower slide seats 10 are slidably mounted on the heat-setting head 5 located on the inner side of the inverted U-shaped connecting frame 4, and the two lower slide seats 10 are slidably mounted on the heat-setting head 5 located on the inner side of the inverted U-shaped connecting frame 4. 0 are rotatably connected with rotating brackets 9, and the two rotating brackets 9 are rotatably arranged crosswise, the top ends of the two rotating brackets 9 are rotatably connected with upper slides 8 respectively, the bottom of the movable block 7 is provided with a movable groove 701, and the two upper slides 8 are slidably installed in the movable groove 701, and a second spring 12 is fixedly connected between the two upper slides 8; the ends of the two lower slides 10 away from each other are fixedly connected with the first spring 11, and the other end of the first spring 11 is fixedly connected to the side wall of the inverted U-shaped connecting frame 4; the top two sides of the movable block 7 are fixedly connected with the third spring 13 arranged vertically, and the top end of the third spring 13 is fixedly connected to the top side inner wall of the inverted U-shaped connecting frame 4.

[0022] In this embodiment, the heat setting head 5 is adapted to the arched punch 6, and the heat setting head 5 is a hollow structure. An arc-shaped electric heating plate 501 is fixedly arranged at the bottom of the heat setting head 5, and a protective layer 502 is arranged on the bottom side of the arc-shaped electric heating plate 501 to prevent the arc-shaped electric heating plate 501 from directly acting on the shoe upper.

[0023] In this embodiment, a transverse guide rod 14 is fixedly installed in the movable groove 701, and the second spring 12 and the upper slide 8 are both movably mounted on the transverse guide rod 14 in the horizontal direction; a transverse guide hole 801 is provided on the upper slide 8, and the upper slide 8 is movably mounted on the transverse guide rod 14 in the horizontal direction through the transverse guide hole 801; a transverse slider 15 is provided at the bottom of the lower slide 10, and a transverse slide groove is provided on the top of the heat setting head 5, and the transverse slider 15 is slidably installed in the transverse slide groove in the horizontal direction.

[0024] See also Figure 1-3The shoe upper heating and shaping mechanism shown in the figure, when the shoe upper is heated and shaped by the heat setting head 5, the U-shaped connecting frame 4 and the heat setting head 5 are driven downward by the extension of the output end of the electric cylinder 3, and then the arc-shaped electric heating plate 501 and the protective layer 501 at the bottom of the heat setting head 5 are used to pressurize and heat-shape the shoe upper placed on the arched punch 6. And in the process of applying pressure and heat setting to the shoe upper, when the shoe upper is subjected to excessive pressure, its heat setting head 5 and U-shaped connecting frame 4 can move upward with buffering relative to the movable block 7. When the U-shaped connecting frame 4 moves upward, the third spring 13 will be stretched. At the same time, when the heat setting head 5 moves upward, the two rotating brackets 9 will be prompted to rotate crosswise, thereby making the two lower slide seats 10 move away from each other and squeeze the first spring 11. At the same time, when the two rotating brackets 9 rotate crosswise, the two upper slide seats 8 are also prompted to move away from each other and stretch the second spring 12. In this way, through the buffering cooperation of the first spring 11, the second spring 12, and the third spring 13, the effect of buffering and energy dissipation can be greatly achieved, thereby solving the problem that the prior art easily causes excessive pressure to be applied during the heat setting process of the shoe upper due to the lack of buffering function, thereby causing quality deformation or damage to the shoe upper, which is conducive to better meeting the needs of high-quality production.

[0025] Finally, the upper heating and shaping mechanism can effectively prevent the upper from being deformed or damaged due to excessive pressure by adding a buffer structure, which is beneficial to improving the quality of the finished upper, thereby ensuring the qualified rate of the product, reducing production costs, and avoiding waste of resources. At the same time, it can better adapt to uppers of different materials and thicknesses, expand the scope of application, further enhance the reliability and practicality of the entire device, and help better meet the needs of high-quality production.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
