Description

Technical Field

[0001] This utility model relates to the technical field of rubber tire vulcanizing machines, specifically a rubber tire vulcanizing machine with uniform vulcanization and efficient heat dissipation. Background Technology

[0002] A rubber tire vulcanizing machine is a device used to vulcanize rubber tires. It primarily reacts rubber materials with a vulcanizing agent under high temperature and pressure, causing them to solidify into tires with elasticity and wear resistance. The vulcanization process is a crucial step in tire manufacturing, improving the physical and chemical properties of rubber and making it more suitable for withstanding the weight of vehicles and various stresses during driving. Existing tire vulcanizing machines simply place the tire carcass within the pressure plate, failing to fix and support it. This results in inconsistencies in tire carcass stability and uniform vulcanization during the process, leading to uneven stress distribution under pressure and affecting the vulcanization effect.

[0003] According to the patent application published on the Internet, a rubber tire vulcanizing machine with uniform vulcanization and efficient heat dissipation (authorization announcement number: CN221912874U) is described as including "drive mechanism, adjustment mechanism, hydraulic cylinder" etc. to carry out vulcanization work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This rubber tire vulcanizing machine, which features uniform vulcanization and efficient heat dissipation, utilizes a drive mechanism, adjustment mechanism, and hydraulic cylinders for vulcanization. However, during operation, this vulcanizing machine only places the tire blank in the lower pressure plate and supports the bottom of the tire blank, failing to fix and support the inner side of the tire blank. This results in poor support and an inability to ensure the tire blank remains stable during use. Consequently, when the upper and lower pressure plates close, the tire blank cannot be subjected to uniform pressure, thus affecting the vulcanization effect. Therefore, this vulcanizing machine needs improvement. Utility Model Content

A support frame is fixedly connected to the right side of the movable frame. A unidirectional threaded rod is rotatably connected to the bottom of the fixing frame. A second servo motor is fixedly connected to the bottom of the unidirectional threaded rod. A movable platform is threadedly connected to the periphery of the unidirectional threaded rod. A sliding rod is slidably connected inside the movable platform. A connecting shaft is fixedly connected to the top of the movable platform. A lifting block is fixedly connected to the top of the connecting shaft. The lifting block is slidably connected to the inside of the lower pressure plate.

[0009] Preferably, the movable frame extends through the interior of the lower pressure plate, and the interior of the support platform and the lower pressure plate are respectively provided with sliding grooves, and the two sliding grooves correspond to each other. The movable frame is slidably connected in the sliding grooves, which facilitates the movement of the support frame under the action of the movable frame.

[0010] Preferably, the lifting block extends through the interior of the support platform, and the support platform and the lower pressure plate are respectively provided with movable grooves, and the two movable grooves correspond to each other. The lifting block is slidably connected in the movable groove, so that the vulcanized tire can be pushed out of the lower pressure plate under the action of the lifting block.

[0011] Preferably, the top of the slide rod is fixedly connected to the bottom of the support platform, the bottom of the slide rod is fixedly connected to the top of the vulcanizing machine body, and the second servo motor is fixedly connected to the top of the vulcanizing machine body, so that the moving platform can move more stably under the action of the slide rod.

[0012] Preferably, there are two sets of mounting brackets and fans, which are respectively located on the left and right sides of the support platform to facilitate heat dissipation of the vulcanized tires under the action of the fans.

[0013] Preferably, the vulcanizing mechanism includes a support frame, which is fixedly connected to the top of the support platform. A hydraulic cylinder is fixedly connected to the top of the support frame, and an upper pressure plate is fixedly connected to the bottom of the hydraulic cylinder. The upper pressure plate is located on top of the lower pressure plate. A second sealing seat is fixedly connected to the periphery of the upper pressure plate. The second sealing seat is located on top of the first sealing seat. A round rod is fixedly connected to the top of the upper pressure plate and is slidably connected inside the support frame.

[0015] Compared with the prior art, this utility model provides a rubber tire vulcanizing machine with uniform vulcanization and efficient heat dissipation, which has the following beneficial effects:

[0016] 1. This rubber tire vulcanizing machine, featuring uniform vulcanization and efficient heat dissipation, utilizes a fixed mechanism. During the vulcanization process, the tire blank is placed at the bottom of the lower pressure plate, stabilizing it initially. Simultaneously, depending on the blank's size, the support frame moves under the action of the bidirectional threaded rod and the moving frame, bringing the outer edge of the support frame into contact with the inner side of the blank. This provides support and fixation, ensuring more uniform pressure and vulcanization during the process, improving the vulcanization effect. It can also provide fixed support for blanks of different sizes. Upon completion of vulcanization, the connecting shaft and lifting block move under the action of the unidirectional threaded rod and the moving table, lifting the vulcanized tire out of the lower pressure plate. A fan then dissipates heat from the tire. Even after vulcanization, the tire's interior remains at a high temperature; without timely cooling, the vulcanization reaction may continue, leading to over-vulcanization. Heat dissipation improves the tire's cooling efficiency, enhancing subsequent processing efficiency.

[0017] 2. This rubber tire vulcanizing machine with uniform vulcanization and efficient heat dissipation, through its vulcanization mechanism, allows the upper pressure plate and second sealing seat to move under the action of a hydraulic cylinder when the rubber tire is vulcanizing during production and the tire blank is fixed in the lower pressure plate. This causes the bottom of the upper pressure plate to contact the top of the lower pressure plate and moves the round rod, thus vulcanizing the tire blank. The action of the round rod ensures the stability of the upper pressure plate during movement and the uniformity of vulcanization pressure. Furthermore, the bottom of the second sealing seat contacts the top of the first sealing seat, further ensuring the sealing between the upper and lower pressure plates. Attached Figure Description

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-7 This utility model provides a technical solution: a rubber tire vulcanizing machine with uniform vulcanization and efficient heat dissipation, including a vulcanizing machine body 1, a fixing mechanism 2 is provided on the top of the vulcanizing machine body 1, and a vulcanizing mechanism 3 is provided on the top of the fixing mechanism 2.

[0032] The fixing mechanism 2 includes a support column 21, which is fixedly connected to the top of the vulcanizing machine body 1. A load-bearing platform 22 is fixedly connected to the top of the support column 21. A lower pressure plate 25 is fixedly connected to the top of the load-bearing platform 22. A first sealing seat 26 is fixedly connected to the periphery of the lower pressure plate 25. A mounting frame 23 is fixedly connected to the left side of the load-bearing platform 22.

A first servo motor 28 is fixedly connected to the right side of the fixing frame 27. A bidirectional threaded rod 292 is fixedly connected to the left side of the first servo motor 28. The left side of the bidirectional threaded rod 292 is rotatably connected to the fixing frame 27. Inside, a movable frame 291 is threadedly connected to the outer periphery of the bidirectional threaded rod 292. The movable frame 291 is slidably connected to the inside of the support platform 22. A support frame 293 is fixedly connected to the right side of the movable frame 291. A unidirectional threaded rod 29 is rotatably connected to the bottom of the fixed frame 27. A second servo motor 294 is fixedly connected to the bottom of the unidirectional threaded rod 29. A movable table 295 is threadedly connected to the outer periphery of the unidirectional threaded rod 299. A slide rod 296 is slidably connected inside the movable table 295. A connecting shaft 298 is fixedly connected to the top of the movable table 295. A lifting block 297 is fixedly connected to the top of the connecting shaft 298. The lifting block 297 is slidably connected to the inside of the lower pressure plate 25.

[0033] The movable frame 291 extends through the interior of the lower pressure plate 25. The interiors of the support platform 22 and the lower pressure plate 25 are respectively provided with sliding grooves, and the two sliding grooves correspond to each other. The movable frame 291 is slidably connected in the sliding groove, so that the support frame 293 can be moved under the action of the movable frame 291. The lifting block 297 extends through the interior of the support platform 22. The interiors of the support platform 22 and the lower pressure plate 25 are respectively provided with movable grooves, and the two movable grooves correspond to each other. The lifting block 297 is slidably connected in the movable groove, so that the vulcanized tire can be pushed out of the lower pressure plate 25 under the action of the lifting block 297.

[0034] The top of the slide bar 296 is fixedly connected to the bottom of the support platform 22, and the bottom of the slide bar 296 is fixedly connected to the top of the vulcanizing machine body 1. The second servo motor 294 is fixedly connected to the top of the vulcanizing machine body 1, so that the moving platform 295 can move more stably under the action of the slide bar 296. There are two sets of mounting brackets 23 and fans 24. The two sets of mounting brackets 23 and fans 24 are respectively set on the left and right sides of the support platform 22, so that the vulcanized tires can be cooled by the action of the fans 24.

[0035] Example 2

[0036] Please see Figure 1-7 Furthermore, based on Embodiment 1, the vulcanizing mechanism 3 further includes a load-bearing frame 31, which is fixedly connected to the top of the load-bearing platform 22. A hydraulic cylinder 33 is fixedly connected to the top of the load-bearing frame 31, and an upper pressure plate 34 is fixedly connected to the bottom of the hydraulic cylinder 33. The upper pressure plate 34 is located on the top of the lower pressure plate 25, and a second sealing seat 35 is fixedly connected to the periphery of the upper pressure plate 34. The second sealing seat 35 is located on the top of the first sealing seat 26, and a round rod 32 is fixedly connected to the top of the upper pressure plate 34. The round rod 32 is slidably connected to the inside of the load-bearing frame 31. The bottom of the upper pressure plate 34 is in contact with the top of the lower pressure plate 25, and the bottom of the second sealing seat 35 is in contact with the top of the first sealing seat 26. This facilitates further sealing between the upper pressure plate 34 and the lower pressure plate 25 under the action of the first sealing seat 26 and the second sealing seat 35.

[0037] In actual operation, when this device is used, during the vulcanization process of rubber tire production, the tire blank is placed at the bottom of the lower pressure plate 25 to make the tire blank initially stable. At the same time, according to the size of the tire blank, the first servo motor 28 drives the moving frame 291 and the support frame 293 connected to the outer thread of the bidirectional threaded rod 292 to move. The spacing between the support frames 293 is adjusted so that the outer side of the support frame 293 contacts the inner side of the tire blank. Under the action of the support frame 293, the tire blank is supported and fixed, so that the tire blank is pressed and vulcanized more evenly during the vulcanization process, thus improving the vulcanization effect.

[0038] Once the fixing is complete, the upper pressure plate 34 can be moved by the hydraulic cylinder 33, which in turn moves the second sealing seat 35 and causes the round rod 32 to slide inside the load-bearing frame 31. This allows the bottom of the upper pressure plate 34 to contact the top of the lower pressure plate 25, and the bottom of the second sealing seat 35 to contact the top of the first sealing seat 26. This further ensures the sealing between the upper pressure plate 34 and the lower pressure plate 25, allowing the tire blank to be vulcanized under the action of the upper pressure plate 34 and the lower pressure plate 25.

[0039] When vulcanization is complete, the upper pressure plate 34 can be moved away from the top of the lower pressure plate 25. At the same time, the second servo motor 294 drives the moving table 295, which is threadedly connected to the outer side of the one-way threaded rod 29, to move. The moving table 295 slides around the slide rod 296, which in turn drives the connecting shaft 298 and the lifting block 297 to move. Under the action of the lifting block 297, the vulcanized tire is pushed out of the lower pressure plate 25. The fan 24 cools the tire. The inside of the vulcanized tire still maintains a high temperature. If it is not cooled in time, the vulcanization reaction may continue, resulting in over-vulcanization of the tire. Cooling can improve the cooling efficiency of the tire and improve the efficiency of subsequent processing.
