Description

Technical Field

[0001] The invention belongs to the technical field of vulcanizing machines, in particular to a central mechanism of a vulcanizing machine capable of quickly replacing bladders. Background Art

[0002] Vulcanizer is a kind of equipment widely used in rubber processing and plastic processing operations. It is mainly used in the vulcanization process, that is, through heating and pressurizing, the molecular structure of rubber or other materials is cross-linked, so that its performance is improved and it becomes stronger, more durable and heat-resistant.

[0003] The core component of the vulcanizer is its central mechanism, which is mainly used to support and adjust the heating, pressurization, control and other functions during the vulcanization process, and ensure that the entire vulcanization process is carried out efficiently and evenly. The central mechanism of the vulcanizer is mainly composed of: hydraulic system, heating system, mold system, control system, cooling system, press plate mechanism and automatic unloading system. When the central mechanism of the vulcanizer is working, the vulcanizing bladder is used to produce the formed tire.

[0004] The capsules in the vulcanizer need to be replaced regularly after long-term use. When the capsules are in use, they will generate high temperatures in conjunction with the vulcanizer, making it difficult to replace the capsules. Because the capsules themselves have a certain high temperature, it is not easy for workers to replace them. At the same time, under high temperatures, the vulcanization process usually causes the capsules of rubber products to expand or soften. The outer shell of the vulcanization capsule (such as metal or certain high-temperature plastics) will soften or expand under high temperatures, and the vulcanizer (such as sulfur and other chemicals) in the capsule will also activate and react, which will cause the contact between the capsule and the rubber product to become very close, making it difficult to complete a quick replacement.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 10 As shown, a vulcanizer central mechanism capable of quickly replacing bladders according to an embodiment of the present invention comprises a vulcanizer body 1, on which a connecting shaft 2 is provided, on which a vulcanizing bladder 3 is fixedly sleeved; a cooling mechanism 10 is provided on the vulcanizer body 1, and the cooling mechanism 10 comprises two rectangular grooves 11 symmetrically opened in the vulcanizer body 1, in which a rectangular block 12 is provided, and a connecting pipe 13 connected to the interior is fixedly installed at one end of the rectangular block 12, an air pump 14 is provided on one side of the vulcanizer body 1, and one end of the connecting pipe 13 away from the rectangular block 12 is connected to the air pump 14, and one end of the rectangular block 12 away from the connecting pipe 13 is provided with an arc-shaped connecting ring 15, and the connecting ring 15 is connected to the rectangular block 12 through a connecting pipe 17, and a surface of the connecting ring 15 close to the vulcanizing bladder 3 is provided with a plurality of first air outlet holes 16 connected to the interior.

[0023] Specifically, a telescopic assembly 18 is provided in the rectangular groove 11, and the telescopic assembly 18 includes a fixed plate 181 fixedly sleeved on the rectangular block 12, and a plurality of rolling balls 183 are engraved on the top and bottom of the fixed plate 181, and a spring 182 is fixedly installed between the fixed plate 181 and the rectangular groove 11, and a first magnetic block 184 is fixedly installed in the rectangular groove 11, and a second magnetic block 185 is fixedly installed on the side of the fixed plate 181 away from the spring 182. A lifting assembly 19 is provided at the bottom of the rectangular block 12, and the lifting assembly 19 includes an "L"-shaped base 191 fixedly installed at the bottom of the rectangular block 12, and an electric push rod 192 is fixedly installed on the base 191, and the output end of the electric push rod 192 is fixedly connected to the connecting ring 15, and the output end of the electric push rod 192 is sleeved with a bellows 193, and the top of the bellows 193 is fixedly connected to the connecting ring 15, and the bottom of the bellows 193 is fixedly connected to the electric push rod 192.

[0024] Specifically, the connecting ring 15 is provided with an extension mechanism 20, which includes two extension tubes 21 symmetrically distributed with the connecting ring 15, the extension tubes 21 slide in the connecting ring 15, the extension tubes 21 are connected with the inside of the connecting ring 15, a second air outlet 22 connected with the inside is provided on one side of the extension tube 21, a connecting plate 23 is fixedly installed at one end of the extension tube 21 away from the connecting ring 15, a bolt 24 is threadedly connected to the connecting plate 23, and a threaded hole 25 penetrating the connecting plate 23 is provided on one side of the connecting plate 23. A filter screen 26 and two guide plates 27 are fixedly installed in both the first air outlet 16 and the second air outlet 22, the two guide plates 27 are symmetrically distributed, and the guide plates 27 are arc-shaped.

[0025] During operation, when the vulcanizing bladder 3 on the connecting shaft 2 needs to be disassembled and replaced, the fixing plates 181 in the two rectangular grooves 11 are slid so that the two fixing plates 181 move toward each other through the two rectangular blocks 12 and the two connecting rings 15. After the fixing plates 181 move to the appropriate position, the first magnetic block 184 on one side thereof will attract the second magnetic block 185 in the rectangular groove 11, thereby temporarily fixing the rectangular block 12, the fixing plates 181 and the connecting ring 15. It should be noted here that the mutual attraction between the first magnetic block 184 and the second magnetic block 185 is greater than the force of the spring 182, so the fixing plates 181 will not reset with the rectangular block 12. Then, by sliding the extension tubes 21 at both ends of the two connecting rings 15, the two extension tubes 21 on the two connecting rings 15 move toward each other, and at this time, the two connecting plates 23 abut against each other, and the bolts 24 are screwed into the threaded holes 25 of the other connecting plate 23 to be fixed, so that the two connecting rings 15 and the four extension tubes 21 form a ring shape and surround the vulcanizing bladder 3. Then, the air pump 14 on one side of the vulcanizer body 1 is started, and the gas in the air pump 14 enters the connecting ring 15 and the extension tube 21 through the connecting pipe 13, the rectangular block 12, and the connecting tube 17, and the gas is blown toward the vulcanizing bladder 3 through the first air outlet 16 and the second air outlet 22. When the gas passes through the first air outlet 16 and the second air outlet 22, it will pass through the filter 26 and the two arc-shaped guide plates 27. The two guide plates 27 guide the gas to the surroundings, thereby filling the gap between the two first air outlets 16, so that the gas can be blown out in a wider range. With the continuous blowing of the first outlet hole and the second outlet hole 22, the electric push rod 192 on the base 191 is started, and the electric push rod 192 is used to move the connecting ring 15 and the extension tube 21 upward, so as to blow air to the vulcanization bladder 3 in all directions, avoiding blowing air only to the bottom of the vulcanization bladder 3.

[0026] The cooling mechanism 10 designed as above can realize rapid air blowing and cooling of the vulcanization capsule 3, and the telescopic component 18 is used to make the gas closer to the vulcanization capsule 3 when blowing out, so as to achieve the effect of precise air blowing and cooling. In combination with the lifting component 19, the air blowing cooling zone is no longer limited to the bottom of the vulcanization capsule 3, but the entire vulcanization capsule 3 is rapidly cooled. Cooling can restore the capsule surface to a more stable state, which is convenient for disassembly or operation, and avoids deformation or adhesion of the capsule to the equipment due to high temperature, ensuring a smooth disassembly process. At the same time, air blowing and cooling can reduce the risk of thermal expansion or excessive softening of the capsule, thereby ensuring the integrity of the capsule structure during the disassembly process. The cooled vulcanization capsule 3 can be quickly disassembled by the staff, and the disassembly efficiency is greatly improved.

[0027] A sweeping mechanism 30 is provided on the top of the connecting ring 15, and the sweeping mechanism 30 includes an elastic block 31 fixedly mounted on the top of the connecting ring 15 and an inclined fixed column 32, a sliding rod 34 is sealed and slidably connected inside the fixed column 32 through a reset assembly 37, the elastic block 31 and the fixed column 32 are connected through an air pipe 33, a brush plate 35 is fixedly mounted on one end of the sliding rod 34 away from the fixed column 32, and a baffle 36 is fixedly mounted on one side of the vulcanizer body 1. The reset assembly 37 includes a sealing plate 371 fixedly mounted on one end of the sliding rod 34, and the sealing plate 371 and the fixed column 32 are connected by an elastic rope 372.

[0028] Specifically, the sealing plate 371 is provided with a delay assembly 38 for assisting the sliding rod 34 in delaying the reset. The delay assembly 38 includes two limit posts 381 fixedly mounted on the sealing plate 371. The limit posts 381 are made of rubber and gradually increase in size from one end close to the sealing plate 371 to one end away from the sealing plate 371. The fixed post 32 is provided with a limit groove 382 adapted to the limit posts 381. The bottom of the baffle 36 is provided with an extrusion assembly 39. The extrusion assembly 39 includes two side plates 391 fixedly mounted on the bottom of the baffle 36 and symmetrically distributed. A slide plate 392 is slidably connected to the side plates 391.

[0029] During operation, when the disassembly of the old vulcanization bladder 3 is completed and a new vulcanization bladder 3 needs to be installed on the connecting shaft 2, the connecting pipe 13 and the air pump 14 are removed, and the end of the connecting pipe 13 away from the rectangular block 12 is connected to the storage box containing the lubricant, and the lubricant is sprayed onto the surface of the connecting shaft 2 by the connecting pipe 13, and the surface of the connecting shaft 2 is evenly sprayed with the lubricant by the lifting assembly 19. As the connecting ring 15 continues to rise, the elastic block 31 at the top of the connecting ring 15 will be located between the two side plates 391 and the slide plate 392, and the two side plates 391 and the two slide plates 392 will cover the elastic block 31, and the slide plate 392 can slide and shrink into the side plates 391 as the connecting ring 15 rises. At this time, the baffle 36 squeezes the elastic block 31, so that the gas in the elastic block 31 quickly enters the fixed column 32 through the air pipe 33, and slides out in the direction of the connecting column through the sealing plate 371, the slide rod 34 and the brush plate 35 in the fixed column 32. When the sealing plate 371 slides, it will slide with the elastic rope 372 and the limiting column 381, and drive the limiting column 381 to be stuck in the limiting column 381 and temporarily fixed. At this time, the brush of the brush plate 35 is in contact with the surface of the connecting shaft 2. As the electric push rod 192 brings the connecting ring 15 back to the original position, the baffle 36 no longer squeezes the elastic block 31, and the gas in the fixing column 32 slowly returns to the elastic block 31 through the air pipe 33. Since the limiting column 381 is stuck in the limiting groove 382, ​​the sealing plate 371 will not immediately bring the sliding rod 34 and the brush plate 35 back to the original position, but slowly brings the limiting column 381 out of the limiting groove 382 to return, thereby leaving time for the brush plate 35 to brush the lubricating oil on the surface of the connecting shaft 2 evenly when the electric push rod 192 descends.

[0030] The lubricating oil is applied to the surface of the connecting shaft 2 through the above-designed mechanism, and the delay component 38 is designed to evenly apply the lubricating oil to the surface of the connecting shaft 2. Applying the lubricating oil can form a thin film between the contact surface of the vulcanizing bladder 3 and the connecting shaft 2, reduce the friction of direct contact, help make the installation process smoother, reduce the resistance of the bladder during installation, prevent it from getting stuck or deformed, and thus facilitate the quick installation of the vulcanizing bladder 3.

[0031] Working principle: When the vulcanizing bladder 3 on the connecting shaft 2 needs to be disassembled and replaced, the fixing plates 181 in the two rectangular grooves 11 are slid so that the two fixing plates 181 move toward each other through the two rectangular blocks 12 and the two connecting rings 15. After the fixing plates 181 move to the appropriate position, the first magnetic block 184 on one side of the fixing plates 181 will attract the second magnetic block 185 in the rectangular groove 11, thereby temporarily fixing the rectangular block 12, the fixing plates 181 and the connecting ring 15. It should be noted here that the mutual attraction between the first magnetic block 184 and the second magnetic block 185 is greater than the force of the spring 182, so the fixing plates 181 will not reset with the rectangular block 12. Then, by sliding the extension tubes 21 at both ends of the two connecting rings 15, the two extension tubes 21 on the two connecting rings 15 move toward each other, and at this time, the two connecting plates 23 abut against each other, and the bolts 24 are screwed into the threaded holes 25 of the other connecting plate 23 to be fixed, so that the two connecting rings 15 and the four extension tubes 21 form a ring shape and surround the vulcanizing bladder 3. Then, the air pump 14 on one side of the vulcanizer body 1 is started, and the gas in the air pump 14 enters the connecting ring 15 and the extension tube 21 through the connecting pipe 13, the rectangular block 12, and the connecting tube 17, and the gas is blown toward the vulcanizing bladder 3 through the first air outlet 16 and the second air outlet 22. When the gas passes through the first air outlet 16 and the second air outlet 22, it will pass through the filter 26 and the two arc-shaped guide plates 27. The two guide plates 27 guide the gas to the surroundings, thereby filling the gap between the two first air outlets 16, so that the gas can be blown out in a wider range. With the continuous blowing of the first outlet hole and the second outlet hole 22, the electric push rod 192 on the base 191 is started, and the electric push rod 192 is used to move the connecting ring 15 and the extension tube 21 upward, so as to blow air to the vulcanization bladder 3 in all directions, avoiding blowing air only to the bottom of the vulcanization bladder 3.

[0032] When the disassembly of the old vulcanization bladder 3 is completed and a new vulcanization bladder 3 needs to be installed on the connecting shaft 2, the connecting pipe 13 and the air pump 14 are removed, and the end of the connecting pipe 13 away from the rectangular block 12 is connected to the storage box containing the lubricant, and the lubricant is sprayed onto the surface of the connecting shaft 2 by the connecting pipe 13, and the surface of the connecting shaft 2 is evenly sprayed with the lubricant by the lifting assembly 19. As the connecting ring 15 continues to rise, the elastic block 31 on the top of the connecting ring 15 will be located between the two side plates 391 and the slide plate 392, and the two side plates 391 and the two slide plates 392 will cover the elastic block 31, and the slide plate 392 can slide and shrink into the side plates 391 as the connecting ring 15 rises. At this time, the baffle 36 squeezes the elastic block 31, so that the gas in the elastic block 31 quickly enters the fixed column 32 through the air pipe 33, and slides out in the direction of the connecting column through the sealing plate 371, the slide bar 34 and the brush plate 35 in the fixed column 32. When the sealing plate 371 slides, it will slide with the elastic rope 372 and the limiting column 381, and drive the limiting column 381 to be stuck in the limiting column 381 and temporarily fixed. At this time, the brush of the brush plate 35 is in contact with the surface of the connecting shaft 2. As the electric push rod 192 brings the connecting ring 15 back to the original position, the baffle 36 no longer squeezes the elastic block 31, and the gas in the fixing column 32 slowly returns to the elastic block 31 through the air pipe 33. Since the limiting column 381 is stuck in the limiting groove 382, ​​the sealing plate 371 will not immediately bring the sliding rod 34 and the brush plate 35 back to the original position, but slowly brings the limiting column 381 out of the limiting groove 382 to return, thereby leaving time for the brush plate 35 to brush the lubricating oil on the surface of the connecting shaft 2 evenly when the electric push rod 192 descends.
