Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a multi-material shoe upper quick bonding device. Background Technology

[0002] Multi-material upper bonding involves heat-pressing different materials together. Each material has its own unique performance advantages, such as leather's strong abrasion resistance and good support, mesh fabric's excellent breathability, and TPU material's good elasticity and durability. By bonding multiple materials, these advantages can be combined, improving the shoe's comfort, support, abrasion resistance, and breathability.

[0003] With the increasing diversification of shoe upper materials, different materials require different bonding methods. Transparent or semi-transparent plastic uppers and smooth leather uppers often use UV adhesives cured by ultraviolet light, while fabric uppers often use hot melt adhesives cured by hot pressing. Large-area fabric uppers and synthetic leather uppers are cured by cold pressing with ordinary glue. However, existing shoe upper bonding equipment lacks corresponding bonding methods, making it inconvenient to quickly bond uppers of multiple materials. Furthermore, the lack of cushioning during the bonding process means that the pressure applied by the equipment cannot be evenly distributed on the shoe upper surface, resulting in some areas of the upper being subjected to excessive stress while others are subjected to insufficient stress. Areas subjected to excessive stress are prone to deformation and damage, while areas subjected to insufficient stress may result in loose bonding. At the same time, rigid bonding methods also generate significant impact forces, further increasing the risk of damage to the shoe upper and reducing the product qualification rate.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a device for rapid bonding of multi-material shoe uppers.

[0026] This utility model provides, for example Figure 1-3 The multi-material shoe upper quick bonding device shown includes a preheating chamber 1, an L-shaped support base 2 fixedly connected to the top of the preheating chamber 1, a first hydraulic cylinder 3 fixedly connected to the top of the L-shaped support base 2, a second hydraulic cylinder 4 fixedly connected inside the cavity of the preheating chamber 1, a heating mounting base 5 fixedly connected to the other end of the first hydraulic cylinder 3 and the second hydraulic cylinder 4 through a buffer mechanism, a locking interface 6 opened at one end of the heating mounting base 5, and a pressing mold 7 is locked in place, and a limiting mechanism is provided between the pressing mold 7 and the heating mounting base 5;

[0027] The preheating chamber 1 has positioning grooves 8 on both sides of its cavity, and a supporting slide plate 9 is slidably connected to them. Infrared preheating lamps 10 and ultraviolet curing lamps 11 are fixedly connected to the bottom ends of the supporting slide plate 9. An electric push rod 12 is fixedly connected to one end of the cavity of the preheating chamber 1, and one end of the electric push rod 12 is fixedly connected to the side wall of the supporting slide plate 9. A U-shaped cooling spray plate 13 is fixedly connected to the top end of the preheating chamber 1. A control display 14 is fixedly connected to the side wall of the L-shaped support seat 2. The infrared preheating lamp 10 and ultraviolet curing lamp 11 installed inside the preheating chamber 1 can quickly raise the temperature of the shoe surface and enhance the activity of the adhesive, which is suitable for hot melt adhesives and other adhesives that require heating and activation, thus speeding up the bonding speed. The ultraviolet curing lamp 11 can cure the UV adhesive in a short time, meeting the bonding requirements of different shoe surface materials under different adhesive processes. The electric push rod 12 can be used to flexibly adjust the position of the supporting slide plate 9, thereby driving the infrared preheating lamp 10 and the ultraviolet curing lamp 11. The linear curing lamp 11 moves to adapt to shoe uppers of different sizes and shapes. A limiting mechanism is provided between the pressing mold 7 and the heating mounting base 5 to ensure precise installation of the pressing mold 7. The pressing mold 7 can be replaced with a suitable one for different shoe upper materials, achieving diverse bonding methods. This facilitates rapid bonding of shoe uppers made of various materials such as leather, mesh, and synthetic materials, significantly improving the equipment's applicability and production efficiency. The device is controlled using a control display 14. The first hydraulic cylinder 3 and the second hydraulic cylinder 4 are connected to the heating mounting base 5 through a buffer mechanism. During the pressing process, the buffer mechanism drives the heating mounting base 5 and the pressing mold 7 to apply pressure evenly, effectively avoiding damage to the shoe upper caused by uneven force, ensuring pressing quality, and improving product qualification rate. This solves the problems of existing shoe upper bonding equipment lacking corresponding bonding methods, being inconvenient for rapid bonding of shoe uppers made of various materials, and experiencing uneven force during the pressing process.

[0028] To buffer the pressure and apply it evenly, such as Figure 2 and 3 As shown, the buffer mechanism includes a buffer chamber 15, a slide rod 16, a perforated slide plate 17, and a buffer damper 18. One end of each of the two heated mounting bases 5 is fixedly connected to a buffer chamber 15. Perforated slide plates 17 are fixedly connected between the top and bottom of the inner sidewalls at both ends of the buffer chamber 15. The sidewalls of the perforated slide plates 17 are fixedly connected to one end of the first hydraulic cylinder 3 and the second hydraulic cylinder 4, respectively. A buffer damper 18 is fixedly connected between the sidewalls of the buffer chamber 15 and the perforated slide plate 17. Using this buffer mechanism composed of the buffer chamber 15, slide rod 16, perforated slide plate 17, and buffer damper 18, the buffer chamber 15 is considered as a whole. The support frame provides a mounting base for the buffer components. Its two ends are fixedly connected to the heating mounting base 5 to ensure the stability of the buffer mechanism in the pressing equipment. The slide rod 16 provides guidance for the sliding of the perforated slide plate 17, ensuring the stability and accuracy of its movement. The perforated slide plate 17 is connected to the first hydraulic cylinder 3 and the second hydraulic cylinder 4. During the pressing process, if excessive local pressure occurs when the hydraulic cylinder pushes the perforated slide plate 17 to move, the buffer damper 18 can play a key role. The buffer damper 18 is set between the buffer chamber 15 and the side wall of the perforated slide plate 17, and it has elastic buffering and damping adjustment functions.

[0029] To facilitate the disassembly of the pressing mold 7 and the replacement with different molds, such as Figure 1-3 As shown, the limiting mechanism includes a U-shaped socket 19, a plate 20, a threaded limiting hole 21, and a threaded limiting pin 22. The top ends of the two-end pressing mold 7 are fixedly connected to the U-shaped socket 19, and the bottom ends of the two-end heating mounting base 5 are fixedly connected to the plate 20. The two-end plate 20 is inserted into the corresponding U-shaped socket 19. The plate 20 and the U-shaped socket 19 have corresponding threaded limiting holes 21, and are threadedly connected to the threaded limiting pin 22. By using the limiting mechanism composed of the U-shaped socket 19, plate 20, threaded limiting hole 21, and threaded limiting pin 22, the U-shaped socket 19 at both ends is positioned and inserted into the plate 20, and then the threaded limiting pin 22 is threadedly connected to the corresponding threaded limiting hole 21. This allows for quick installation between the pressing mold 7 and the heating mounting base 5, and facilitates direct separation of the two by rotating and removing the threaded limiting pin 22, making it convenient to replace different molds for use.

[0030] In order to provide a cold air source for the U-shaped cooling spray plate 13, such as Figure 1 and 2 As shown, a cold air fan 23 is fixedly connected to the other end of the top of the preheating chamber 1. A connecting pipe 24 is fixedly connected to the output end of the cold air fan 23. The other end of the connecting pipe 24 passes through the side wall of the L-shaped support 2 and is fixedly connected to the output end of the U-shaped cooling spray plate 13. The cold air fan 23 and the connecting pipe 24 are used to provide a cold air source to the U-shaped cooling spray plate 13.

[0031] In order for the heating mounting base 5 to transfer heat to the pressing mold 7, such as Figure 3 As shown, a resistance wire assembly 25 is fixedly connected to one end of the cavity of the heating mounting base 5, and an electrical control assembly 26 is fixedly connected to the other end of the cavity of the heating mounting base 5. The electrical control assembly 26 is electrically connected to the resistance wire assembly 25. By using the electrical control assembly 26 to control the resistance wire assembly 25 to heat up and perform hot pressing, heat is transferred to the pressing mold 7.

[0032] To achieve the air outlet function, such as Figure 1 and 2 As shown, the U-shaped cooling spray plate 13 is a U-shaped hollow plate, and multiple air outlet nozzles 27 are provided on the inner side wall. By using the U-shaped cooling spray plate 13, which is a U-shaped hollow plate with multiple air outlet nozzles 27 on the inner side wall, the air outlet function is achieved through the multiple air outlet nozzles 27.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
