Description

Technical Field

[0001] This invention relates to the field of heat press technology, and in particular to an integrated hot and cold pressing machine for shoe uppers. Background Technology

[0002] In the field of shoe upper processing, for multi-layered shoe uppers (such as those containing composite structures like fabrics, linings, and reinforcing layers), a combined hot-pressing and cold-pressing process is typically used to achieve a stable bond between the layers. The specific process is as follows: First, the multi-layered shoe upper material is positioned and clamped onto a specialized fixture. A set temperature and pressure are applied to the multi-layered upper on the fixture using a hot-pressing device, allowing the adhesives (or the inherent heat-melting properties of the materials themselves) to function, initially achieving interlayer bonding. Subsequently, a cold-pressing device is used to cool and shape the hot-pressed upper, preventing deformation and interlayer separation due to excessively high temperatures after hot pressing, thus ensuring the quality of the shoe upper processing. However, in existing shoe upper pressing processes, the transfer of fixtures between the hot pressing and cold pressing processes largely relies on manual operation. This manual transfer method has significant drawbacks: First, it is labor-intensive. The fixtures themselves have a certain weight, and frequent transfers are necessary to ensure processing efficiency. The repetitive handling and transfer of fixtures by workers over extended periods can easily lead to occupational health problems such as muscle strain. Second, it is inefficient. Manual fixture transfer involves operational intervals (such as time spent by workers picking up and placing fixtures, and the time spent on movement paths), making it impossible to achieve continuous connection between the hot pressing and cold pressing processes. This results in a prolonged overall processing cycle, making it difficult to meet the needs of large-scale production. Third, it poses significant safety hazards. After hot pressing, the fixtures and shoe uppers still maintain high temperatures (typically tens to over one hundred degrees Celsius). Inadequate protection during manual transfer can easily lead to burns to the hands, posing a threat to the personal safety of workers. In summary, the existing shoe upper pressing process, which relies on manual transfer fixtures, has significant shortcomings in terms of labor intensity, processing efficiency, and operational safety. It has become a key issue restricting the improvement of quality and efficiency and the guarantee of production safety in the shoe upper processing industry. There is an urgent need to propose a technical solution that can replace manual transfer fixtures to solve the above-mentioned technical pain points. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an integrated hot and cold pressing machine for shoe uppers.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention discloses a shoe upper hot and cold pressing integrated machine, comprising a frame; a jig lifting assembly and a plurality of pressing and forming machines are arranged along the frame; a jig conveying mechanism is provided on the frame; the jig conveying mechanism is used to convey the jig between the pressing and forming machines and the jig lifting assembly.

[0005] Furthermore, the pressing and forming machine includes a second lifting linear module, a lower support platform fixed on the frame, and a pressure plate slidably connected to the frame; both ends of the second lifting linear module are respectively fixed to the frame.

[0006] Furthermore, the fixture conveying mechanism includes a lower translation linear module and an upper translation linear module; hook bodies are provided on both sides of the lower translation linear module and both sides of the upper translation linear module; hooks for use in conjunction with the hook bodies are provided on both the left and right sides of the fixture.

[0007] Furthermore, both the lower translation linear module and the upper translation linear module consist of two parallel belt conveyor lines; the hook body is fixed on the belt of the belt conveyor line.

[0008] Furthermore, a straight groove is formed on one side wall of the hook; a countersunk hole is provided on the bottom surface of the hook; the end of the straight groove is connected to the countersunk hole; the diameter of the countersunk hole is larger than the width of the straight groove. The hook body includes a telescopic component with one end fixed to the fixture conveying mechanism, a limiting rod fixed to the other end of the telescopic component, and a positioning ring fixed to the end of the limiting rod; the diameter of the positioning ring is greater than the width of the straight groove; the diameter of the positioning ring is not greater than the diameter of the countersunk hole; the diameter of the limiting rod is less than the width of the straight groove.

[0009] With the above structure, the beneficial effects of this invention are as follows: the fixture conveying mechanism first conveys the fixture on the fixture lifting assembly to the hot press station, where the hot press presses and shapes the product on the fixture; then, the fixture conveying mechanism drives the fixture with the hot-pressed product to the cold press, where the cold press cold-presses the product; the fixture conveying mechanism continues to drive the fixture to move, outputting the cold-pressed product to the fixture lifting assembly to form a cycle; this structure enables the fixture to be cyclically transferred and conveyed between the fixture lifting assembly and multiple pressing and shaping machines; reducing labor intensity and safety hazards, and improving processing efficiency.

Detailed Implementation

[0011] The invention will now be further described with reference to the accompanying drawings.

[0012] like Figures 1 to 7 As shown, the shoe upper hot and cold pressing integrated machine of the present invention includes a frame 4; the frame 4 is provided with a jig lifting assembly 1 and a plurality of pressing and forming machines 6; a jig conveying mechanism is provided on the frame 4; the jig conveying mechanism is used to convey jigs 3 between the pressing and forming machines 6 and the jig lifting assembly 1. These compression molding machines 6 consist of a hot press and a cold press. Hot pressing is performed first, followed by cold pressing. In this embodiment, one hot press and one cold press are used. The fixture conveying mechanism first transports the fixture 3 on the fixture lifting assembly 1 to the hot press station, where the hot press presses and shapes the product on the fixture 3; then the fixture conveying mechanism drives the fixture 3 with the hot-pressed product to the cold press, where the cold press cold-presses the product; the fixture conveying mechanism continues to drive the fixture 3 to move, outputting the cold-pressed product to the fixture lifting assembly 1 to form a cycle; This structure enables the jig 3 to be cyclically transferred and conveyed on the jig lifting assembly 1 and multiple pressing and forming machines 6; reducing labor intensity and safety hazards, and improving processing efficiency.

[0013] In a preferred embodiment of the present invention, the pressing and forming machine 6 includes a second lifting linear module 603, a lower support platform 601 fixed on the frame 4, and a pressure plate 602 slidably connected to the frame 4; the two ends of the second lifting linear module 603 are respectively fixed to the frame 4. The second lifting linear module 603 is not fundamentally different from existing technology, so it will not be discussed in detail here; In the hot press, heating rods are installed inside both the lower support platform 601 and the pressure plate 602, and the heating plates are connected to the circuit. In the cold press, cooling water channels are installed inside both the lower support platform 601 and the pressure plate 602, and the cooling water channels are connected to the external circulating cooling water channels. The top surfaces of each lower support platform 601 are on the same horizontal plane, so that the fixture 3 can move parallel between two adjacent lower support platforms 601. The second lifting linear module 603 can drive the pressure plate 602 to move up and down, and is used to press the product on the fixture 3 onto the lower support platform 601 for heating or cooling.

[0014] In a preferred embodiment of the present invention, the fixture conveying mechanism includes a lower translational linear module 2 and an upper translational linear module 5; hook bodies 7 are provided on both sides of the lower translational linear module 2 and both sides of the upper translational linear module 5; hooks 301 for use in conjunction with hook bodies 7 are provided on both the left and right sides of the fixture 3. After the hook 301 is engaged with the hook body 7, the fixture 3 is connected to the hook body 7, and the fixture 3 can move on the lower translation linear module 2 and the upper translation linear module 5; the fixture lifting assembly 1 is used to transfer the fixture 3 from the lower translation linear module 2 to the upper translation linear module 5.

[0015] In a preferred embodiment of the present invention, both the lower translational linear module 2 and the upper translational linear module 5 are composed of two parallel belt conveyor lines; the hook body 7 is fixed on the belt of the belt conveyor line. The belt conveyor is not fundamentally different from existing technology, so it will not be described in detail. The two belt conveyors of the same lower translation linear module 2 move synchronously, and the two belt conveyors of the same upper translation linear module 5 move synchronously. The upper translation linear module 5 is responsible for transferring the fixture 3 from the fixture lifting assembly 1 to the first hot press at the front end. The lower translation linear module 2 transfers the fixture 3 from the first hot press at the front end into the cold press and finally into the fixture lifting assembly 1 to complete a cycle of fixture 3 conveying.

[0016] In a preferred embodiment of the present invention, a straight groove 30101 is provided on one side wall of the hook 301; a countersunk hole 30102 is provided on the bottom surface of the hook 301; the end of the straight groove 30101 is connected to the countersunk hole 30102; the diameter of the countersunk hole 30102 is larger than the width of the straight groove 30101. The hook body 7 includes a telescopic component 701 with one end fixed to the fixture conveying mechanism, a limiting rod 702 fixed to the other end of the telescopic component 701, and a positioning ring 703 fixed to the end of the limiting rod 702; the diameter of the positioning ring 703 is greater than the width of the straight groove 30101; the diameter of the positioning ring 703 is not greater than the diameter of the countersunk hole 30102; the diameter of the limiting rod 702 is smaller than the width of the straight groove 30101. The positioning ring 703 on the lower translation linear module 2 is oriented upwards. The telescopic component 701 drives the limiting rod 702 and the positioning ring 703 to telescopically move, which, in conjunction with the translational movement of the lower translation linear module 2, allows the positioning ring 703 on the lower translation linear module 2 to be embedded into the countersunk hole 30102 from bottom to top. Then, the lower translation linear module 2 drives the positioning ring 703 of the hook body 7 to move, so that the fixture moves synchronously with the lower translation linear module 2. When it is necessary to place the fixture 3 on the fixture lifting component 1 or the pressing and forming machine 6, only the telescopic component 701 needs to descend, and the positioning ring 703 can be pulled out from the countersunk hole 30102. The positioning ring 703 on the upper translation linear module 5 is oriented downwards; the telescopic component 701 on the upper translation linear module 5 first lowers the positioning ring 703 to a position below the bottom surface of the hook 301, then the upper translation linear module 5 moves, causing the limiting rod 702 to be embedded in the straight groove 30101, and finally the telescopic component 701 drives the positioning ring 703 to rise, inserting the positioning ring 703 from bottom to top into the countersunk hole 30102, using the limiting rod 702 and the positioning ring 703 to suspend the hook 301; then it is transported through the upper translation linear module 5.

[0017] When the fixture 3 is transferred from the upper translation linear module 5 to the lower translation linear module 2, the telescopic component 701 extends directly, placing the fixture 3 onto the pressing and forming machine 6, and then the limiting rod 702 on the upper translation linear module 5 is pulled out from the straight groove 30101.

[0018] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
