Description

Technical Field

[0001] The invention relates to the technical field of tire processing, in particular to a vulcanizing device for manufacturing high-vulcanization-activity rubber tires. Background Art

[0002] High-vulcanization-activity rubber tires need to be vulcanized during the production process, and a vulcanizer is required in this process. At present, vulcanizers usually use model pressurization to vulcanize tires. The specific operation is: place the green tire between a sealed vulcanization bladder and a vulcanization mold. Saturated steam is introduced into the vulcanization bladder to heat the vulcanization bladder and the vulcanization mold to provide the heat required for vulcanization to the green tire, and then high-pressure nitrogen is introduced into the vulcanization bladder to provide the pressure required for vulcanization. The vulcanization bladder expands and squeezes the green tire, and the vulcanizer is used to shape and vulcanize the green tire to improve the strength of the tire. When the above scheme is used, the volume of the vulcanization bladder needs to be expanded to the same volume as the inner cavity of the green tire first, and gas continues to be introduced into the vulcanization bladder to achieve heating or extrusion operations on the green tire. When the vulcanized rubber is taken out, the gas in the vulcanization bladder needs to be completely discharged, which undoubtedly increases the tire vulcanization time and reduces the tire vulcanization speed. When taking and placing the tire, the staff needs to reach under the mold with their hands or tools, which reduces the safety and work efficiency during use. Based on this, the present application proposes a vulcanization equipment for manufacturing high vulcanization activity rubber tires. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The top of the mobile seat 2 is fixed with a lower mold 9 adapted to the rubber tire, the middle of the mobile seat 2 is provided with a fixing hole 16, a blocking connection structure is provided below the fixing hole 16, a groove is provided outside the fixing hole 16, a limit ring 17 adapted to the green tire is movably connected in the inner cavity of the groove, the limit ring 17 is connected to the mobile seat 2 through the hydraulic telescopic rod 18, the depth of the groove is not less than the height of the limit ring 17, and the limit ring 17 can be completely hidden in the inner cavity of the groove under the action of the hydraulic telescopic rod 18, so as to avoid the limit ring 17 from restricting the tire and facilitate the vulcanization of the rubber tire. The depth of the groove can be set according to demand and is not limited here.

[0030] The blocking connection structure includes a hydraulic telescopic rod 5 19 fixedly connected to the mobile seat 2 and a mobile plate 20 connected to the hydraulic telescopic rod 5 19. The extension and retraction of the hydraulic telescopic rod 5 19 can change the position of the mobile plate 20 fixedly connected thereto. A limiting rod 24 is fixedly connected to one end of the top of the mobile plate 20. The outer ring of the limiting rod 24 is movably sleeved with the blocking rod 21. A spring groove is provided in the middle of the limiting rod 24. A spring 23 is fixedly connected to the bottom of the inner cavity of the spring groove. The other end of the spring 23 is fixedly connected to the top of the inner cavity of the blocking rod 21. Through the setting of the limiting rod 24, the limiting rod 24 can limit the blocking rod 21 and limit the moving height of the blocking rod 21; through the setting of the spring 23, the distance between the blocking rod 21 and the limiting rod 24 can be changed, and when the restriction on the blocking rod 21 is released, the rebound force of the spring 23 can push the blocking rod 21 to move.

[0031] The height of the blocking rod 21 is the same as the depth of the fixing hole 16 . The blocking rod 21 can be used to block the fixing hole 16 to prevent impurities from falling into the inner cavity of the fixing hole 16 .

[0032] A pressure sensor 22 is fixedly connected to the bottom of the blocking rod 21 . By setting the pressure sensor 22 , the position of the blocking rod 21 can be detected to ensure the movement accuracy of the blocking rod 21 .

[0033] An air inlet pipe 26 and an exhaust pipe 25 are disposed at the other end of the movable plate 20. Electric ball valves are disposed at one end of both the air inlet pipe 26 and the exhaust pipe 25. The electric ball valves can be used to control the air inlet speed and the exhaust speed.

[0034] The bottom end of the inner cavity of the sealing cover 5 is provided with an upper mold adapted to the lower mold 9. The middle part of the sealing cover 5 is connected to the airbag structure through a hydraulic telescopic rod four 11. The extension and retraction of the hydraulic telescopic rod four 11 can change the position of the airbag structure fixedly connected thereto.

[0035] The airbag structure includes an insertion rod 7 adapted to the fixing hole 16, and the insertion rod 7 is fixedly connected to the end of the output shaft of the hydraulic telescopic rod 11. When the vulcanization equipment is in use, the bottom end of the insertion rod 7 is inserted into the inner cavity of the fixing hole 16, and the bottom of the insertion rod 7 is at the same height as the top of the blocking rod 21. At this time, the pressure sensor 22 can be used to monitor the insertion depth of the insertion rod 7 to ensure the insertion accuracy of the insertion rod 7.

[0036] The bottom end of the plug rod 7 is evenly fixedly connected with a hydraulic telescopic rod 6 13, and the other end of the hydraulic telescopic rod 6 13 is connected with a vulcanization capsule 10 through a shaping block 12. Through the setting of the hydraulic telescopic rod 6 13, the extension and contraction of the hydraulic telescopic rod 6 13 can change the position of the shaping block 12 fixedly connected thereto, and when the position of the shaping block 12 changes, the vulcanization capsule 10 can be pulled to change the volume of the vulcanization capsule 10. A connecting pipe 15 adapted to the air intake pipe 26 and the exhaust pipe 25 is fixed on the vulcanization capsule 10. The connecting pipe 15 is a telescopic pipe. The material of the connecting pipe 15 can be a high temperature and high pressure resistant corrugated pipe. There are at least two connecting pipes 15, and when the air intake pipe 26 and the exhaust pipe 25 are in contact with the bottom of the plug rod 7, the top of the air intake pipe 26 is tightly fitted with the bottom of one connecting pipe 15, and the top of the exhaust pipe 25 is tightly fitted with the bottom of the other connecting pipe 15.

[0037] The top of the insertion rod 7 is evenly fixedly connected with a hydraulic telescopic rod 7 8, the bottom of the hydraulic telescopic rod 7 8 is fixedly connected with a hydraulic telescopic rod 8 14, and the other end of the hydraulic telescopic rod 8 14 is fixedly connected with another shaping block 12. The extension and retraction of the hydraulic telescopic rod 7 8 can change the position of the hydraulic telescopic rod 8 14 fixedly connected thereto, and the extension and retraction of the hydraulic telescopic rod 8 14 can change the position of the other shaping block 12 fixedly connected thereto. The hydraulic telescopic rod 6 13 and the hydraulic telescopic rod 8 14 are alternately arranged, and the shaping block 12 is an arc structure. All shaping blocks 12 in the airbag structure can form an annular structure adapted to the inner diameter of the green tire. At this time, the annular structure supports the vulcanization bladder 10 into an annular structure. When the vulcanization bladder 10 is inflated, the vulcanization bladder 10 can expand evenly.

[0038] From the above description of the airbag structure, it can be seen that during the vulcanization process of the rubber tire, the shaping block 12 can occupy a part of the space inside the green tire, reduce the amount of gas required when the vulcanization bladder 10 squeezes the green tire, increase the speed at which the gas contacts the tire, and thus increase the vulcanization speed of the green tire.

[0039] The outer surface of the sealing cover 5 is wrapped with a heat-insulating pad, and the material of the heat-insulating pad can be pearl cotton. By setting the heat-insulating pad, the heat loss during the tire vulcanization process can be reduced, and the energy consumption of the equipment can be reduced.

[0040] In summary: when the vulcanization equipment for manufacturing high-vulcanization active rubber tires is used, when it is necessary to place a raw tire of the vulcanization active rubber tire, the movable seat 2 and the sealing cover 5 are in a staggered state, and the hydraulic telescopic rod 18 is extended, and the hydraulic telescopic rod 18 drives the limiting ring 17 to move into the inner cavity of the lower mold 9, and the limiting ring 17 can limit the raw tire. After the raw tire is placed in the inner cavity of the lower mold 9, the hydraulic telescopic rod 13 is contracted until the movable seat 2 moves to the bottom of the sealing cover 5, the hydraulic telescopic rod 18 is contracted, and the hydraulic telescopic rod 18 drives the limiting ring 17 to move downward until the limiting ring 17 is hidden in the inner cavity of the groove. In the cavity, the hydraulic telescopic rod three 4 contracts, and the hydraulic telescopic rod three 4 drives the sealing cover 5 to move downward. When the sealing cover 5 is completely fitted with the bottom of the base 1, the lower mold 9 and the upper mold are molded together, and during the contraction of the hydraulic telescopic rod three 4, the hydraulic telescopic rod four 11 extends, and the hydraulic telescopic rod four 11 drives the airbag structure to move downward until the bottom of the insertion rod 7 and the top of the blocking rod 21 are at the same height, and the hydraulic telescopic rod four 11 contracts, and the contraction height of the hydraulic telescopic rod four 11 is the same as the contraction height of the hydraulic telescopic rod three 4, so that the position of the airbag structure remains fixed, and the insertion rod 7 squeezes the blocking rod 2 during the insertion process. 1, when the blocking rod 21 moves downward and the insertion rod 7 is completely inserted into the fixing hole 16, the blocking rod 21 is separated from the fixing hole 16, and the pressure sensor 22 detects the pressure, the hydraulic telescopic rod five 19 drives the moving plate 20 to move, and the moving plate 20 drives the blocking rod 21 to move, so that the blocking rod 21 is staggered with the fixing hole 16, until the air intake pipe 26 and the exhaust pipe 25 move to the bottom of the fixing hole 16, at this time, the top of the air intake pipe 26 is tightly fitted with the bottom of the connecting pipe 15, and the top of the exhaust pipe 25 is tightly fitted with the bottom of the other connecting pipe 15; during the contraction process of the hydraulic telescopic rod four 11, the hydraulic telescopic rod six 13 The shaping block 12 is driven to move, and the shaping block 12 moves into the inner cavity of the green tire. The hydraulic telescopic rod 7 8 drives the hydraulic telescopic rod 8 14 to move downward until the position of the hydraulic telescopic rod 8 14 is at the same height as the position of the hydraulic telescopic rod 4 11. The hydraulic telescopic rod 8 14 is extended, and the hydraulic telescopic rod 8 14 drives another shaping block 12 connected thereto to move until the other shaping block 12 forms a ring structure with the shaping block 12, and a part of the cavity of the green tire is occupied by the ring structure. The amount of gas required for the vulcanization bladder 10 to squeeze the green tire is reduced, and the gas can quickly contact and squeeze the green tire, thereby increasing the vulcanization speed of the green tire. The gas (steam + high-pressure nitrogen) required in the tire vulcanization process enters the inner cavity of the vulcanization bladder 10 through the air inlet pipe 26 and the connecting pipe 15 in contact with the air inlet pipe 26, increasing the volume of the vulcanization bladder 10, and the excess gas in the vulcanization bladder 10 is discharged through another connecting pipe in contact with the exhaust pipe 25 and the exhaust pipe 25.

[0041] During demoulding, the vulcanization capsule 10 is deflated. After the other shaping block 12 is separated from the vulcanization capsule 10, the hydraulic telescopic rod eight 14 and the hydraulic telescopic rod seven 8 drive the other shaping block 12 to reset, and the hydraulic telescopic rod four 11 drives the shaping block 12 connected thereto to reset, thereby realizing the separation of the airbag structure from the high-vulcanization active rubber tire. The hydraulic telescopic rod three 4 drives the sealing cover 5 to move upward, and the sealing cover 5 drives the upper mold and the airbag structure to move upward. When the airbag structure moves to the top of the tire, the hydraulic telescopic rod one 3 extends, and the hydraulic telescopic rod one 3 drives the moving seat 2 to move until the moving seat 2 is staggered with the sealing cover 5, so as to facilitate the taking and placing of the tire.
