[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a continuous vulcanization processing equipment for silicone rubber, including a support frame 1, on which an installation mechanism for continuous vulcanization processing of silicone rubber is provided, the installation mechanism including:
[0024] The feeding assembly includes a support frame 1 with a mounting platform 2 fixed at the upper end, an extruder body 201 fixed at the upper end of the mounting platform 2, an extrusion shaft 3 inside the extruder body 201, a feed inlet 202 fixed at the upper end of the extruder body 201, and a mixing assembly for material entry inside the feed inlet 202.
[0025] The installation components include an extruder body 201 with a cavity groove 401 inside the outlet, a slip ring block 404 connected by an elastic component inside the cavity groove 401, a die body 408 connected by an engagement component inside the slip ring block 404, and a discharge pipe 4 connected by a sliding component at one end of the die body 408.
[0026] In a preferred embodiment, the mixing assembly includes a drive shaft 203 rotatably connected inside the feed inlet 202. A mixing rod 204 is uniformly fixed to the outer wall of the drive shaft 203. Three sets of scraper supports 205 are fixed to the upper outer wall of the drive shaft 203. The scraper supports 205 are in close contact with the inner wall of the feed inlet 202. Silicone rubber raw material is added into the extruder body 201 through the feed inlet 202. The drive shaft 203 rotates via a motor, causing the mixing rods 204 uniformly fixed to the outer wall of the drive shaft 203 to rotate accordingly, mixing the incoming raw material and ensuring uniform mixing of its components. Simultaneously, the three sets of scraper supports 205 fixed to the upper outer wall of the drive shaft 203 also rotate. Since the scraper supports 205 are in close contact with the inner wall of the feed inlet 202, they scrape away the raw material adhering to the inner wall of the feed inlet 202 during rotation. The motor model is Y2-200L1-2Y.
[0027] The stirring action of the stirring rod 204 allows the various components in the silicone rubber raw material to be fully mixed, which helps to improve the performance and quality of the final product. The scraper bracket 205 can clean the raw material on the inner wall of the feed inlet 202 in a timely manner, avoiding raw material accumulation and blockage, and ensuring production continuity and stability.
[0028] In a preferred embodiment, the elastic component includes a spring 402 uniformly fixed to the inner wall of the cavity groove 401, a slip ring block 404 fixedly connected to the other end of the spring 402, and a sliding connection between the slip ring block 404 and the cavity groove 401. A telescopic sleeve 403 is provided on the inner ring of the spring 402, with both ends of the telescopic sleeve 403 fixedly connected to the slip ring block 404 and the inner wall of the cavity groove 401, respectively. The engaging component includes a connecting housing 405 fixed to one end of the slip ring block 404, and the interior of the connecting housing 405 is open. A mounting groove 406 is provided, and a mounting block 407 is engaged inside the mounting groove 406. The die body 408 is fixedly connected to the other end of the mounting block 407. The sliding assembly includes positioning rods 409 evenly fixed to the outer wall of the die body 408. A vulcanizing chamber body 6 is fixed to the right side wall of the support frame 1. The discharge pipe 4 is located at the upper end of the vulcanizing chamber body 6. A positioning shell 5 is fixed to the upper end of the discharge pipe 4. The positioning shell 5 has a positioning groove 501 that slides with the positioning rods 409 inside. The die body 408 is fixed to the other end of the mounting block 407. 8 is connected to the slip ring block 404 via a snap-fit assembly. One end of the slip ring block 404 is fixedly connected to the housing 405. An installation groove 406 is opened inside the housing 405. The mounting block 407, which is fixed to one end of the die body 408, snaps into the installation groove 406. At the same time, an external force is applied to the housing 405, causing the slip ring block 404 to slide in the cavity groove 401, compressing the spring 402 and the telescopic sleeve 403, aligning the other end of the die body 408 with the positioning housing 5 on the discharge pipe 4. The mounting block 407 is subjected to the external force of the connection. The elastic force of the shell 405 and the spring 402 allows the positioning rod 409 on the outer wall of the die body 408 to be inserted into the positioning groove 501 inside the positioning shell 5, thus achieving a sliding connection between the die body 408 and the discharge pipe 4. Through the design of the elastic component and the locking component, the die is easy to disassemble and install, improving production efficiency. During the extrusion process, the die body 408 slides relative to the discharge pipe 4 as it is pushed forward by the extrusion shaft, but always maintains a stable connection, allowing the silicone rubber profile to be smoothly extruded from the die and enter the vulcanization chamber body 6 for vulcanization treatment.
[0029] The sliding connection between the positioning rod 409 and the positioning groove 501 ensures the stability of the die body 408 during the extrusion process, avoids deviation or shaking, and improves extrusion accuracy and quality. The elastic action of the spring 402 and the telescopic sleeve 403 keeps the slip ring block 404 in a stable position within the cavity groove 401, ensuring the stability and accuracy of the die during the extrusion process.
[0030] In a preferred embodiment, a vulcanizing pipe 602 is fixedly installed inside the vulcanizing chamber body 6. A heating pipe 603 with a threaded structure is uniformly fixed on the outer wall of the vulcanizing pipe 602. Heat dissipation grooves 601 are uniformly opened on the outer wall of the vulcanizing chamber body 6. After the silicone rubber profile is extruded from the extruder into the vulcanizing chamber body 6, the heating pipe 603 works to heat the vulcanizing pipe 602, raising the internal temperature of the vulcanizing pipe 602 to the temperature required for vulcanization. The silicone rubber profile undergoes a cross-linking reaction under the action of high temperature and vulcanizing agent in the vulcanizing pipe 602, forming a three-dimensional network structure and completing the vulcanization process. At the same time, heat dissipation grooves 601 are uniformly opened on the outer wall of the vulcanizing chamber body 6 to increase the contact area with the outside.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0032] During operation, the silicone rubber raw material is first added into the extruder body 201 through the feed port 202. The motor drives the drive shaft 203 to rotate, and the stirring rods 204, which are uniformly fixed on the outer wall of the drive shaft 203, rotate accordingly to stir the incoming raw material and make its components evenly mixed. At the same time, the three sets of scraper supports 205, which are fixed on the outer wall of the upper end of the drive shaft 203, also rotate together. Because the scraper supports 205 are in contact with the inner wall of the feed port 202, they scrape off the raw material adhering to the inner wall of the feed port 202 during the rotation.
[0033] Then, the die body 408 is connected to the slip ring block 404 via a snap-fit assembly. Specifically, a mounting groove 406 is formed inside the connecting housing 405, which is fixed at one end of the slip ring block 404. A mounting block 407, fixed at one end of the die body 408, snaps into the mounting groove 406. Simultaneously, an external force is applied to the connecting housing 405, causing the slip ring block 404 to slide within the cavity groove 401, compressing the spring 402 and the telescopic sleeve 403. This aligns the other end of the die body 408 with the positioning housing 5 on the discharge pipe 4. The mounting block 407 is subjected to the elastic force of the connecting housing 405 and the spring 402. The positioning rod 409 on the outer wall of the 08 is inserted into the positioning groove 501 inside the positioning shell 5 to achieve a sliding connection between the die body 408 and the discharge pipe 4. Finally, after the silicone rubber profile enters the vulcanizing chamber body 6, the heating pipe 603 works to heat the vulcanizing pipe 602, raising the internal temperature of the vulcanizing pipe 602 to the temperature required for vulcanization. The silicone rubber profile undergoes a cross-linking reaction under the action of high temperature and vulcanizing agent in the vulcanizing pipe 602, forming a three-dimensional network structure and completing the vulcanization process. At the same time, the heat dissipation grooves 601 evenly opened on the outer wall of the vulcanizing chamber body 6 increase the contact area with the outside.
