[0002] Vulcanizing equipment is a type of equipment used in the production of EVA shoe soles. It vulcanizes and molds the EVA shoe soles, thereby enhancing their performance.
[0003] The vulcanization molding unit has too few workstations, and when workers take out the vulcanized shoe soles, the vulcanization molding unit is idle, which affects production efficiency.
[0004] Chinese patent CN 222792553 U discloses a vulcanization device for EVA shoe sole production, including an operating table, a support platform and a fixing frame disposed on the outside of the operating table, a forming component for shoe sole forming processing disposed on the outside of the fixing frame, an adjusting component for adjusting the position of the template disposed on the outside of the forming component, and a discharge component for removing the formed shoe sole disposed on the outside of the operating table. The forming component includes four bottom molds arranged in a ring outside the support platform, and a hydraulic rod disposed on the outside of the fixing frame. In this invention, after one product is made, a motor drives a connecting rod to rotate, the connecting rod drives a lever to rotate, the lever inserts into a groove to drive a connecting platform to rotate, and the connecting platform drives the rotating rod and the support platform to rotate 90 degrees, just enough to move another bottom mold to the lower part of the upper mold for the production of another shoe sole. Then the finished product is taken out, which can be continuously produced, improving production efficiency.
[0005] However, when using existing technology, a large amount of heat remaining in the mold after the EVA sole vulcanization is directly dissipated through natural cooling, which not only prolongs the mold cooling time and increases the overall production cycle, but also causes energy waste.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0035] like Figures 1-6 As shown, a shoe material thermal vulcanization apparatus includes:
[0036] Workbench 1, on which a rotary drive mechanism 2 is provided, and a rotary table 3 is provided at the drive end of the rotary drive mechanism 2, and a plurality of shoe material lower molds 4 arranged in a ring array are provided on the top of the rotary table 3.
[0037] A bracket 5 is installed on the top of the workbench 1. A lifting drive mechanism 6 is provided on the bracket 5, and a shoe material upper mold 7 is provided at the drive end of the lifting drive mechanism 6.
[0038] The preheating mechanism is located between the rotary table 3 and the worktable 1, and includes a first heat conduction mechanism and a second heat conduction mechanism. The first heat conduction mechanism heats one of the shoe material lower molds 4 through a heating medium, and the second heat conduction mechanism exchanges heat with the first heat conduction mechanism through a cooling medium and preheats the other shoe material lower mold 4.
[0039] In use, the operator first places the shoe material onto the lower mold 4 of the shoe material on top of the rotating table 3. The rotation drive mechanism 2 immediately starts, causing the rotating table 3 to rotate intermittently clockwise or counterclockwise. As the rotating table 3 rotates, the lower molds 4 of the shoe material at different workstations enter the vulcanization area in sequence. At the same time, the lifting drive mechanism 6 on the support 5 precisely controls the lifting and lowering of the upper mold 7 of the shoe material. When the rotating table 3 transports the lower mold 4 of the shoe material loaded with shoe material to the designated position, the upper mold 7 of the shoe material (a heating mechanism, such as a heating sleeve, can be configured on the outside of the upper mold 7. This heating mechanism can be directly used to heat and vulcanize the shoe material. The first heat-conducting structure in this application can also directly vulcanize the shoe material, or it can cooperate with the above-mentioned heating mechanism to vulcanize the shoe material. This is prior art and will not be described in detail here) is activated by the lifting drive mechanism 6. The material descends and fits tightly against the lower mold 4 of the shoe material, automatically completing the mold closing action. Then, the vulcanization process begins, achieving multi-station cyclic vulcanization, which greatly improves production efficiency and effectively reduces the intensity of manual operation and the error rate. During operation, the first heating mechanism introduces a heating medium to heat the lower mold 4 of the shoe material at the current vulcanization position, allowing the shoe material to complete vulcanization under high temperature and pressure. This can be coordinated with the heating mechanism of the upper mold 7 of the shoe material to simultaneously heat the shoe material, improving vulcanization efficiency. After vulcanization, the second heating mechanism absorbs the residual heat from the first heating mechanism through a cooling medium. This cools the vulcanized lower mold of the shoe material, facilitating rapid demolding, and also transfers the recovered heat to the next lower mold of the shoe material to be processed for preheating. When the next rotation enters the vulcanization area, the shoe material is already in a preheated state, resulting in highly efficient and seamless overall process integration.
[0040] This device achieves cyclic vulcanization and waste heat utilization of multi-station shoe material lower molds by setting a first heat conduction mechanism and a second heat conduction mechanism between the rotary table 3 and the worktable 1. The first heat conduction mechanism heats the shoe material lower mold at the vulcanization station through a heating medium, enabling the shoe material to quickly complete high-temperature and high-pressure vulcanization. The second heat conduction mechanism absorbs excess heat through a cooling medium, which not only avoids structural deformation or energy waste caused by prolonged high-temperature residence time of the mold, but also rationally transfers heat to the shoe material lower mold 4 to be processed for preheating, shortening the overall vulcanization cycle, improving mold utilization, and avoiding energy waste and cost increases caused by repeated heating. The entire device has a compact structure, is easy to operate, and can realize automated, multi-station efficient cyclic operation, significantly reducing manual labor intensity and operational error rate, and ensuring a dual improvement in the stability of shoe material product quality and production efficiency.
[0041] As a preferred example of this application, the first heat-conducting mechanism specifically includes a first heat-conducting block 8 embedded in the top of the workbench 1. The first heat-conducting block 8 is made of a metal material with excellent thermal conductivity, which can ensure the uniformity and efficiency of heat conduction. A through-type heating pipe 9 is opened inside the first heat-conducting block 8. Both ends of the heating pipe 9 extend out of the outside of the first heat-conducting block 8 and are connected to an external heat-conducting medium system through a hose or high-temperature resistant pipe. The heat-conducting medium can be hot water, hot oil or other high-efficiency liquid heat-conducting medium. The circulation of the heat-conducting medium can continuously provide stable heat to the first heat-conducting block 8. The first heat-conducting block 8 is adapted to the bottom structure of the rotating table 1 to ensure close contact when the two rotate. After the shoe material lower mold 4 rotates with the rotating table 3 to above the first heat-conducting block 8, the first heat-conducting block 8 quickly conducts the heat stored inside to the shoe material lower mold 4, so that the shoe material lower mold 4 heats up quickly and maintains uniform heating, improving the vulcanization quality of the shoe material. The overall structural design is scientific and reasonable, which not only ensures efficient heat transfer, but also facilitates installation and maintenance.
[0042] This application, by setting an embedded first heat-conducting block 8 and heating tube 9 in the first heat-conducting mechanism, combined with an external high-efficiency heat-conducting medium circulation system, makes the heat transfer process more stable, faster and more controllable, effectively avoiding vulcanization defects caused by uneven local heating or unstable temperature, improving the processing consistency and finished product qualification rate of shoe materials. The overall device has a compact structure, occupies little space, and is easy to integrate and operate in actual production. With the multi-station cyclic operation of the rotary table 3, it can continuously and stably complete the high-efficiency vulcanization processing of large batches of shoe materials, reducing the intensity of manual intervention, saving energy, and improving the overall economic benefits and service life of the equipment.
[0043] As a preferred example of this application, the second heat conduction mechanism includes a second heat conduction block 10 embedded in the top of the workbench 1 and a heat exchange tube 11. The heat exchange tube 11 passes through the first heat conduction block 8 and the second heat conduction block 10 in sequence. The output end and the input end of the heat exchange tube 11 are both connected to an external cooling medium.
[0044] The structure of the heat exchange pipe 11 passing sequentially through the first heat-conducting block 8 and the second heat-conducting block 10 forms a heat exchange channel. Both ends of the heat exchange pipe 11 are connected to an external cooling medium circulation system. The cooling medium can be cold water or other liquid cooling medium. After the first heat-conducting block 8 heats the lower mold 4 of the shoe material to complete the vulcanization, the cooling medium flowing through the heat exchange pipe 11 begins to circulate. The cooling medium first passes through the first heat-conducting block 8, absorbing the residual heat from the heating process, causing the first heat-conducting block 8 to cool down quickly, facilitating the demolding of the vulcanized shoe material. Subsequently, the cooling medium carrying heat continues to flow to the second heat-conducting block 10, releasing the absorbed heat to the second heat-conducting block 10. The second heat-conducting block 10 then transfers this heat to the lower mold 4 of the shoe material to be vulcanized, completing the preheating process. This setup not only effectively cools the completed vulcanization mold but also makes full use of residual heat to preheat the mold to be vulcanized, shortening the heating time of the mold to be vulcanized, optimizing the production cycle, and improving energy efficiency.
[0045] As a preferred example of this application, the heat exchange tube 11 is arranged in a wavy shape inside the second heat-conducting block 10;
[0046] The upper contact surfaces 12 of the first heat-conducting block 8 and the second heat-conducting block 10, and the lower mold 4 of the shoe material are all integrally formed using heat-conducting material. The surface of the heating tube 9 abuts against the inner wall of the upper contact surface 12 of the first heat-conducting block 8, and the surface of the heat exchange tube 11 abuts against the inner wall of the upper contact surface 12 of the second heat-conducting block 10 (the lower mold 4 of the shoe material can conduct heat from its bottom to the mold cavity. At least part of the lower mold 4 of the shoe material is made of heat-conducting material. In this embodiment, the heat-conducting material can be copper). The inner wall of the contact surface 12 of the second heat-conducting block 10 is also wavy.
[0047] The upper contact surfaces 12 of the first heat-conducting block 8 and the second heat-conducting block 10 are designed with an integral heat-conducting material, eliminating the thermal resistance problem in the heat transfer process from the root. In actual operation, when the lower mold 4 of the shoe material rotates with the rotary table 3 to contact the first heat-conducting block 8 or the second heat-conducting block 10, the heat can be directly transferred to the lower mold 4 of the shoe material without any obstruction because the upper contact surface 12 is an integral heat-conducting material. At the same time, the surface of the heating tube 9 is in close contact with the inner wall of the upper contact surface 12 of the first heat-conducting block 8, and the surface of the heat exchange tube 11 is in close contact with the inner wall of the upper contact surface 12 of the second heat-conducting block 10. This close contact method further ensures the high efficiency of heat conduction. Whether in the heating process or the preheating process, the heat can be quickly and evenly transferred to the lower mold 4 of the shoe material, avoiding the phenomenon of local overheating or underheating due to thermal resistance, ensuring the uniformity and stability of temperature during the vulcanization process of the shoe material, thereby improving the quality of the vulcanized shoe material and reducing the defect rate.
[0048] Meanwhile, due to the wavy arrangement of the heat exchange tube 11 inside the second heat-conducting block 10, the wavy path design significantly increases the contact area between the cooling medium and the second heat-conducting block 10 when the cooling medium flows inside the heat exchange tube 11. Compared with the straight heat exchange tube 11, the wavy structure makes the flow path of the cooling medium inside the second heat-conducting block 10 longer and the residence time longer, so that it can exchange heat with the second heat-conducting block 10 more fully. This efficient heat exchange can ensure that it can quickly reach the preheating temperature in a short time, making full preparation for the subsequent vulcanization operation and further improving production efficiency and vulcanization quality.
[0049] As a preferred example of this application, the bottom of the rotary table 3 is provided with a boss 13, the rotary drive mechanism 2 is provided at the bottom of the worktable 1, and the drive end of the rotary drive mechanism 2 is movably connected through the worktable 1 and fixedly connected to the bottom of the boss 13; the tops of the first heat-conducting block 8 and the second heat-conducting block 10 both protrude from the top of the worktable 1 and are provided at the gap 18 between the rotary table 3 and the worktable 1.
[0050] The connection design between the boss 13 at the bottom of the rotary table 3 and the rotary drive mechanism 2 at the bottom of the workbench 1 provides a stable and reliable power transmission for the entire rotary vulcanization process. When the device is running, the rotary drive mechanism 2 (in this embodiment, a combination design of motor + reducer can be adopted, with the motor drive end connected to the reducer input end and the reducer output end connected to the boss 13) is installed at the bottom of the workbench 1. This structural design hides the drive components under the workbench 1, effectively avoiding interference of the drive mechanism with the vulcanization operation above, making it more convenient and safer for operators to place shoe materials and inspect molds above.
[0051] As a preferred example of this application, the lifting drive mechanism 6 includes a cylinder disposed on the top of the bracket 5, and the upper mold 7 of the shoe material is installed at the end of the piston rod of the cylinder. The cylinder, as the core driving component, is installed on the top of the bracket 5, and its piston rod end is rigidly connected to the upper mold 7 of the shoe material. When the rotary table 3 accurately transports the lower mold 4 of the shoe material loaded with shoe material to the vulcanization position, the control system triggers the cylinder to ventilate, and the piston rod extends at a uniform speed under the action of compressed air, pushing the upper mold 7 of the shoe material to descend smoothly.
[0052] As a preferred example of this application, a heating water tank 14 is also included. The output end of the heating tube 9 is connected to the heating water tank 14, and the input end of the heating tube 9 is connected to the heating water tank 14 via a first water pump 15. The coordinated design of the heating water tank 14 and the first water pump 15 constructs a closed and efficient heat transfer medium circulation system, providing a continuous and stable heat source for shoe material vulcanization. During operation, the heat transfer medium (such as water or heat transfer oil) in the heating water tank 14 is heated to a set temperature by the built-in heating element (such as the electric heating tube 9). The first water pump 15 pumps the high-temperature medium into the heating tube 9 at a constant flow rate. When the high-temperature medium flows in the heating tube 9, it fully exchanges heat with the first heat transfer block 8, transferring heat to the shoe material lower mold 4 in contact with it, so that the shoe material reaches the temperature required for vulcanization. In addition, when it is necessary to adjust the vulcanization temperature, only the heating power of the heating water tank 14 needs to be adjusted for a quick response, meeting the vulcanization process requirements of different shoe materials.
[0053] As a preferred example of this application, a cooling water tank 16 is also included. The output end of the heat exchange tube 11 is connected to the cooling water tank 16, and the input end of the heat exchange tube 11 is connected to the cooling water tank 16 through a second water pump 17. The combination of the cooling water tank 16 and the second water pump 17 forms a key closed-loop system for waste heat recovery and mold cooling, which greatly optimizes energy utilization and production cycle. During the heat exchange process, the second water pump 17 pumps the low-temperature medium (such as cooling water at 15-25°C) in the cooling water tank 16 into the heat exchange tube 11 at a stable flow rate. The low-temperature medium first flows through the first heat-conducting block 8 and exchanges heat with the high-temperature first heat-conducting block 8. The medium temperature rises rapidly, and the first heat-conducting block 8 cools down rapidly, which facilitates the demolding of the vulcanized shoe material. At the same time, the second heat-conducting block 10 is preheated. The medium that has absorbed heat flows back to the cooling water tank 16 through the output end and exchanges heat with the external cooling system (such as a cooling tower or air cooler) in the water tank, reducing it to the initial low temperature and participating in the cycle again.
[0054] This application innovatively sets up a first heat conduction mechanism and a second heat conduction mechanism between the rotary table 3 and the worktable 1. Combined with the synergistic design of the high-efficiency heating pipe 9, heat exchange pipe 11, heat conduction block, cooling water tank 16, and heating water tank 14, it forms a high-efficiency circulating vulcanization system that integrates heating of the shoe material lower mold 4, mold cooling, waste heat recovery, and preheating of the lower mold to be processed. This not only realizes continuous operation of multiple stations, significantly shortens the vulcanization cycle, improves mold utilization, avoids deformation and energy waste caused by excessive high temperature dwell time of the mold, and ensures stable and reliable vulcanization temperature of the shoe material, but also makes full use of waste heat resources, reduces overall energy consumption, and improves equipment economy. The overall device has a compact structure, stable operation, and simple operation, and can achieve high efficiency, low energy consumption, and high yield in the shoe material vulcanization process, significantly improving production efficiency and product quality.
