Description

Technical Field

[0001] This utility model relates to the field of rubber processing equipment technology, specifically to a rubber production vulcanization mechanism. Background Technology

[0002] Rubber is a highly elastic, reversibly deformable polymer material that can quickly return to its original shape when stretched by external force at room temperature. This polymer material is divided into two main categories: natural rubber and synthetic rubber. Natural rubber is extracted from the latex of plants such as rubber trees and is made through coagulation and drying. Synthetic rubber is obtained through the chemical polymerization of monomers. Due to its excellent elasticity, insulation, airtightness, and wear resistance, rubber is widely used in industrial products such as tires, seals, and hoses, as well as in everyday consumer goods. The vulcanization process is the core step in rubber processing. By using heat-activated sulfur or crosslinking agents, the rubber molecular chains form a three-dimensional network structure. This process is similar to... By weaving a three-dimensional network to permanently connect loose linear molecular chains, the strength, elasticity, and aging resistance of rubber are significantly improved. The process requires precise control of temperature, time, and pressure: too high a temperature will lead to degradation, while too low a temperature will result in insufficient cross-linking; insufficient time will lead to under-sulfurization, while excessive time will lead to over-sulfurization and brittleness. Ultimately, the rubber is transformed from a viscous flow state to a stable, highly elastic state. However, during the desulfurization process, rapid cooling after heating requires manual handling, and improper operation can easily lead to product deformation and affect the quality of the finished product. Existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber production vulcanization mechanism, comprising: a mechanism base, a mechanism shell, and a longitudinal displacement power shell, wherein the longitudinal displacement power shell is installed on the mechanism shell, the mechanism shell is installed on the mechanism base, and a downward pressure vulcanization coupling structure is installed inside the mechanism shell, wherein the downward pressure vulcanization coupling structure comprises: a longitudinal displacement power motor, a first transmission screw, a displacement bearing module, a pair of mounting and coordinating bearings, a second auxiliary screw, a shell-encased base, a vulcanization air inlet duct, a vulcanization air outlet duct, a pair of symmetrical cooling mounting blocks, and several air guide fans;

[0004] The longitudinal displacement power motor is installed inside the longitudinal displacement power housing. The first transmission screw is installed inside the mechanism housing and is inserted into the housing inner covering base. The displacement bearing module is fitted onto the first transmission screw and the displacement bearing module is fitted onto the second auxiliary screw. A pair of mounting and coordinating bearings are respectively installed inside the mechanism housing and the housing inner covering base. The second auxiliary screw is respectively installed on a pair of mounting and coordinating bearings. The housing inner covering base is installed inside the mechanism housing. The vulcanization inlet air passage is installed on the mechanism housing. The vulcanization outlet air passage is installed on the mechanism housing. A plurality of air guide fans are respectively installed inside the mechanism housing. A pair of symmetrical cooling mounting blocks are respectively installed on the displacement bearing module and the housing inner covering base. A pair of heating and cooling fast switching components are respectively installed on the pair of symmetrical cooling mounting blocks.

[0005] It should be noted that, as described above, the rubber raw material to be vulcanized is placed on the heating and temperature-conducting mounting block inside the housing through the sealed hatch on the housing. This drives the longitudinal displacement motor inside the longitudinal displacement power housing, causing the first transmission screw to rotate. The displacement bearing module is then driven by the rotating thread on the first transmission screw, causing a pair of symmetrical cooling mounting blocks to move closer or further apart inside the housing until the heating and cooling rapid switching components on them are aligned and fitted together, thus heating or cooling the rubber raw material. At the same time, the second auxiliary screw is driven by the vertically moving displacement bearing module, causing it to rotate continuously on a pair of mounting and coordinating bearings. In summary, when the longitudinal displacement motor is running, the displacement bearing module can move stably up and down. Then, the vulcanizing gas enters the housing through the vulcanizing air inlet and is driven downwards inside the housing by the operation of multiple air guide fans until it is discharged from the vulcanizing air outlet. The shock absorbers on the base of the mechanism ensure greater stability throughout the entire operation.

[0006] Preferably, the rapid heating and cooling switching component includes: a pair of thermally conductive copper layers, several connecting keys, a pair of integrated telescopic air rods, a heating and thermally conductive mounting block, a covering constraint frame, and a pair of mounting locking bolts;

[0007] A pair of thermally conductive bonding copper layers are respectively installed on the symmetrical cooling mounting block and the heating thermally conductive mounting block. A plurality of connecting mounting keys are respectively installed on the symmetrical cooling mounting block and the heating thermally conductive mounting block. A pair of integrated telescopic air rods are respectively connected to a plurality of connecting mounting keys. The covering constraint frame is fitted on the heating thermally conductive mounting block. A pair of mounting locking bolts are respectively inserted into the covering constraint frame, and a pair of mounting locking bolts are respectively connected to the heating thermally conductive mounting block.

[0008] It should be noted that, as described above, the appropriate thickness of the covering constraint frame is selected according to the thickness of the rubber raw material to be vulcanized, and a pair of covering constraint frames are installed on a pair of heating and heat-conducting mounting blocks by the corresponding four mounting locking bolts. Then, the heating and heat-conducting mounting block on the base side inside the shell will align with the heating and heat-conducting mounting block on the displacement bearing module side. During this process, the integrated telescopic air rod is always in an extended state. Afterward, the heating and heat-conducting mounting block generates high temperature, which fully heats the rubber material restrained and covered by a pair of enclosure constraint frames and reacts with the vulcanizing gas inside the outer shell of the mechanism. After the reaction is completed, the four integrated telescopic air rods contract synchronously. At the same time, the displacement bearing module continues to move downward, causing the pair of heating and heat-conducting mounting blocks to move closer together again. At the same time, they will adhere to multiple corresponding heat-conducting copper layers. The circulating water circuit set in the symmetrical cooling mounting block starts to work. The high temperature of the rubber product inside the enclosure constraint frame will be conducted to the heat-conducting copper layers through the heating and heat-conducting mounting block. After the heat-conducting copper layers come into contact with each other, they will be conducted to the symmetrical cooling mounting block. Finally, the heat is carried away by the circulating water circuit, thus completing the rapid vulcanization process of the rubber material.

[0009] Preferably, a shock absorber is provided on the base of the mechanism;

[0010] Preferably, the outer casing of the mechanism is provided with a closed hatch;

[0011] Preferably, the longitudinal displacement power housing is provided with a maintenance and inspection port;

[0012] Preferably, the symmetrical cooling block is provided with a circulating water channel.

[0013] Beneficial effects

[0014] This utility model provides a rubber vulcanization mechanism. Compared with existing technologies, this rubber vulcanization mechanism achieves efficient vulcanization of rubber raw materials within the mechanism's outer shell through a downward-pressure vulcanization coupling structure. Vertical pressure technology ensures uniform heating of the rubber compound, significantly improving vulcanization efficiency. After vulcanization, the equipment can quickly switch to cooling mode, minimizing material displacement for cooling and solidification. This seamless integration of hot and cold processes offers three major advantages: first, it shortens the vulcanization-cooling conversion cycle, improving production efficiency; second, it avoids the risk of product deformation caused by traditional handling; and third, precise temperature control strengthens the cross-linking structure of rubber molecules, significantly improving the physical properties of the finished product (such as tensile strength and resilience), making it particularly suitable for the stable production of high-precision rubber products.

[0020] Example

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-2As shown, a rubber vulcanization mechanism includes: a mechanism base 1, a mechanism housing 2, and a longitudinal displacement power housing 3. The longitudinal displacement power housing 3 is mounted on the mechanism housing 2, and the mechanism housing 2 is mounted on the mechanism base 1. A downward-pressure vulcanization coupling structure is installed inside the mechanism housing 2. The downward-pressure vulcanization coupling structure includes: a longitudinal displacement power motor 4, a first transmission screw 5, a displacement bearing module 6, a pair of mounting and coordinating bearings 7, a second auxiliary screw 8, an inner housing covering base 9, a vulcanization air inlet duct 10, a vulcanization air outlet duct 11, a pair of symmetrical cooling mounting blocks 12, and several air guide fans. 19; The longitudinal displacement power motor 4 is installed inside the longitudinal displacement power housing 3, the first transmission screw 5 is installed inside the mechanism housing 2, and the first transmission screw 5 is inserted into the housing inner covering base 9, the displacement bearing module 6 is fitted onto the first transmission screw 5, and the displacement bearing module 6 is fitted onto the second auxiliary screw 8, a pair of mounting and cooperating bearings 7 are respectively installed inside the mechanism housing 2 and the housing inner covering base 9, the second auxiliary screw 8 is respectively installed onto a pair of mounting and cooperating bearings 7, and the housing inner covering base 9 is installed inside the mechanism housing 2. A vulcanizing inlet duct 10 is installed on the outer shell 2 of the mechanism, a vulcanizing outlet duct 11 is installed on the outer shell 2 of the mechanism, several air guide fans 19 are respectively installed inside the outer shell 2 of the mechanism, a pair of symmetrical cooling mounting blocks 12 are respectively installed on the displacement bearing module 6 and the shell-encasing base 9, and a pair of heating and cooling rapid switching components are respectively installed on the pair of symmetrical cooling mounting blocks 12; the heating and cooling rapid switching components include: a pair of thermally conductive bonding copper layers 13, several connecting mounting keys 14, a pair of integrated telescopic air rods 15, a heating and thermally conductive mounting block 16, an encasing constraint frame 17, and a... A pair of temperature-conducting copper layers 13 are respectively installed on the symmetrical cooling block 12 and the heating and temperature-conducting block 16. A plurality of connecting keys 14 are respectively installed on the symmetrical cooling block 12 and the heating and temperature-conducting block 16. A pair of integrated telescopic air rods 15 are respectively connected to a plurality of connecting keys 14. A covering constraint frame 17 is fitted on the heating and temperature-conducting block 16. A pair of locking bolts 18 are respectively inserted into the covering constraint frame 17 and are respectively connected to the heating and temperature-conducting block 16.

[0022] According to the appendix Figure 1-2It is concluded that, through the sealed hatch on the outer shell 2, the rubber raw material to be vulcanized is placed on the heating and heat-conducting mounting block 16 inside the outer shell 2, driving the longitudinal displacement power motor 4 inside the longitudinal displacement power housing 3, thereby causing the first transmission screw 5 to rotate. The displacement bearing module 6 is then driven by the rotating thread on the first transmission screw 5, thus causing a pair of symmetrical cooling mounting blocks 12 to move closer or further apart inside the outer shell 2 until the heating and cooling rapid switching components on them are aligned and fitted together, thus heating or cooling the rubber raw material. At the same time, the second auxiliary screw 8 is driven by the up-and-down moving displacement bearing module 6, thereby causing it to move closer or further apart inside the outer shell 2. The rotating bearing 7 ensures that when the longitudinal displacement motor 4 is running, the displacement bearing module 6 can move stably up and down. Then, the vulcanizing gas enters the housing 2 through the vulcanizing inlet duct 10 and is moved downwards into the housing 2 by the operation of multiple air guide fans 19 until it is discharged from the vulcanizing outlet duct 11. The shock absorber on the base 1 makes the operation more stable throughout the process. The appropriate thickness of the covering constraint frame 17 is selected according to the thickness of the rubber raw material to be vulcanized, and a pair of covering constraint frames 17 are installed on a pair of heating and heat-conducting mounting blocks 16 by the corresponding four mounting locking bolts 18. Then, the heating and heat-conducting mounting block 16 on the side of the base 9 inside the shell will engage with the heating and heat-conducting mounting block 16 on the side of the displacement bearing module 6. During this process, the integrated telescopic air rod 15 is always in an extended state. Afterwards, the heating and heat-conducting mounting block 16 works to generate high temperature, thereby fully heating the rubber material restrained and covered by a pair of covering constraint frames 17, and reacting with the vulcanizing gas inside the outer shell 2 of the mechanism. After the reaction is completed, the four integrated telescopic air rods 15 contract synchronously, and at the same time, the displacement bearing module 6 also continues to... The downward movement causes the pair of heating and heat-conducting mounting blocks 16 to move closer together, while the corresponding heat-conducting copper layers 13 adhere to each other. The circulating water channel inside the symmetrical cooling mounting block 12 then starts working. The high temperature of the rubber product inside the constraint frame 17 is conducted to the heat-conducting copper layers 13 through the heating and heat-conducting mounting blocks 16. After the heat-conducting copper layers 13 come into contact with each other, the heat is conducted to the symmetrical cooling mounting block 12. Finally, the heat is carried away by the circulating water channel, thus completing the rapid vulcanization process of the rubber raw material.
