Description

Technical Field

[0001] The invention relates to the field of tire vulcanization equipment, in particular to an eddy current device of a central mechanism of a tire vulcanizer. Background Art

[0002] At present, a bladder method is known as a tire vulcanizer. In this method, a heating and pressurized medium such as steam or high-temperature gas (for example, inert gas such as nitrogen, or air) is supplied to the interior of a bladder. The bladder is expanded by the supply, thereby pressing the tire onto a mold, thereby vulcanizing the tire.

[0003] For example, the invention patent with publication number CN116604859B discloses a tire vulcanizer, comprising: a ring seat having a central through hole in an axial direction; a vulcanization bladder fixed to the ring seat, and the vulcanization bladder and the upper part of the ring seat jointly define a hollow bladder inner cavity; a rotary drive device, which converts electricity into rotary power, and the rotary drive device comprises: a stator assembly, the upper part of which in the axial direction is fixed to the lower part of the ring seat and has a central through hole, a rotor assembly, at least partially disposed in the central through hole of the stator assembly, and the upper part of the rotor assembly is rotatably disposed in the central through hole of the ring seat; a support cylinder, the upper part of which is detachably fixed to the lower part of the stator assembly; and a center rod, which passes through the support cylinder and the rotor assembly of the rotary drive device, wherein a first cylindrical space is defined between the center rod and the support cylinder, a second cylindrical space is defined between the center rod and the rotor assembly, and the first cylindrical space and the second cylindrical space jointly form a medium channel, and the upper part of the medium channel is connected to the bladder inner cavity of the vulcanization bladder.

[0004] With regard to the above case, in the prior art, during the vulcanization process of the tire, it is necessary to supply high-temperature gas to the interior of the capsule. However, as the high-temperature gas is continuously injected, the capsule will continue to expand, and the internal cavity of the capsule will increase. In addition, since the high-temperature gas directly filled in after heating is in a free-flowing state in the capsule, it is difficult for the high-temperature gas to fully contact the inner wall of the capsule, which can easily lead to uneven distribution of heating temperature on the inner surface of the tire and fail to achieve ideal uniformity. The uneven temperature will not only affect the consistency of tire vulcanization and product quality, but in severe cases may even cause the tire to be scrapped.

[0005] Therefore, the present invention proposes an eddy current device for the central mechanism of a tire vulcanizer to solve the above problems. Summary of the invention

[0077] A plurality of arc-shaped inclined grooves 1201 are provided in a circular array at the top of the rotating shell 12, with one end of the arc-shaped inclined groove 1201 close to the center of the rotating shell 12 and the other end away from the center of the rotating shell 12;

[0078] A plurality of sliding shells 17 are arranged in an annular array at the top of the rotating disk 13. A sliding frame 18 is slidably connected in the sliding shell 17. A first connecting pin 19 is fixedly connected to the bottom end of the sliding frame 18. The bottom end of the first connecting pin 19 passes through the straight groove 1301 and is slidably connected in the arc-shaped inclined groove 1201.

[0079] A first rotation driving mechanism, the first rotation driving mechanism is used to drive the rotating disk 13 to rotate;

[0080] An injection head, which is rotatably connected to the end of the sliding frame 18 to inject high-temperature gas into the bladder 16 to expand the bladder 16, thereby pressing the tire body 9 onto the mold assembly to vulcanize the tire body 9;

[0081] Also includes:

[0082] A flip block 21, which is coaxially fixed with the injection head, and a first elastic connecting member is connected between the flip block 21 and the side wall of the sliding frame 18;

[0083] An I-shaped push frame 26, which is slidably connected to the side wall of the sliding frame 18, and a second elastic connecting member is connected between the I-shaped push frame 26 and the side wall of the sliding frame 18;

[0084] A driving rod 28, both ends of which are fixedly connected to the bottom end of the I-shaped pushing frame 26;

[0085] An annular driving plate 29, the annular driving plate 29 is fixedly connected to the top of the connecting shell 11, and a plurality of protrusions 30 are fixedly connected to the top of the annular driving plate 29 in an annular array;

[0086] The second rotary drive mechanism is used to drive the rotary shell 12 to rotate, so that the drive rod 28 continuously passes through the protrusion 30, and the I-shaped push frame 26 reciprocates up and down. During the up and down movement of the I-shaped push frame 26, the flip block 21 is pushed to flip, so that the injection head is flipped, so as to adjust the injection angle of the injection head, so that the high-temperature gas can contact the side wall of the capsule 16 at different positions, so that the temperature distribution of the inner wall of the capsule 16 is uniform;

[0087] Specifically, in the prior art, during the vulcanization of the tire, high-temperature gas needs to be supplied to the interior of the capsule 16. However, as the high-temperature gas is continuously injected, the capsule 16 will continue to expand, and the internal cavity of the capsule 16 will increase. In addition, since the high-temperature gas directly filled in after heating is in a free-flowing state in the capsule 16, it is difficult for the high-temperature gas to fully contact the inner wall of the capsule 16, which can easily lead to uneven heating temperature distribution on the inner surface of the tire, and it is impossible to achieve ideal uniformity. The uneven temperature will not only affect the consistency of tire vulcanization and product quality, but in severe cases, it may even cause the tire to be scrapped. The present technical solution can solve the above problems, and the specific operations are as follows:

[0088] After the mold assembly clamps the tire body 9 to a limited position, high-temperature gas is injected into the capsule 16 through the injection head. As the high-temperature gas is injected, the capsule 16 begins to expand. During the expansion of the capsule 16, the first rotary drive assembly is first started to rotate the rotary disk 13, so that the first connecting pin 19 slides along the arc-shaped inclined groove 1201. Driven by the arc-shaped inclined groove 1201, the first connecting pin 19 slides along the straight groove 1301, so that the sliding frame 18 extends outward from the sliding shell 17, so that the injection head is close to the inner wall of the capsule 16, thereby reducing the distance between the injection head and the inner wall of the capsule 16, so that the high-temperature gas injected by the injection head can quickly contact the inner wall of the capsule 16, which is conducive to quickly heating up the inner wall of the capsule 16;

[0089] After the sliding frame 18 is extended, the second rotary drive mechanism is started to rotate the rotating shell 12. Under the connection of the first connecting pin 19, the rotating disk 13 is rotated, and the sliding frame 18 drives the injection head to rotate, so that the injection head uniformly injects the high-temperature gas onto the inner wall of the capsule 16, which is conducive to making the temperature distribution in the capsule 16 more uniform, thereby facilitating improving the production quality of the tire body 9;

[0090] In the process of the sliding frame 18 driving the injection head to rotate, the driving rod 28 moves along the top of the annular driving plate 29 and continuously passes through the protrusion 30. Under the push of the protrusion 30, the I-shaped push frame 26 moves up and down reciprocatingly. In the process of the I-shaped push frame 26 moving up and down, the flip block 21 is pushed to flip, so that the injection head is flipped, so as to adjust the injection angle of the injection head, so that the high-temperature gas can contact the side wall at different positions of the capsule 16, further making the temperature distribution of the inner wall of the capsule 16 uniform, which is beneficial to improve the production quality of the tire body 9;

[0091] After the tire body 9 is vulcanized, the rotating shell 12 stops rotating, and then the rotating disk 13 is rotated and reset through the first rotating drive mechanism. Driven by the arc-shaped inclined groove 1201, the sliding frame 18 drives the injection head to retract into the sliding shell 17 to facilitate the contraction of the capsule 16.

[0092] In a specific implementation process, the second rotation drive mechanism includes:

[0093] A second self-locking motor 31, the second self-locking motor 31 is fixedly connected in the lifting column 10, and the top end of the output shaft of the second self-locking motor 31 is fixedly connected to the rotating shell 12;

[0094] The second rotation drive mechanism comprises:

[0095] The first self-locking motor 20 is fixedly connected to the output shaft of the second self-locking motor 31 . The top end of the output shaft of the first self-locking motor 20 passes through the rotating shell 12 and is fixedly connected to the rotating disk 13 .

[0096] During implementation, the first elastic connector includes:

[0097] An arc groove 22, which is formed on the outer side wall of the end of the sliding frame 18;

[0098] The arc-shaped slide bar 23 is fixedly connected in the arc-shaped groove 22. The side wall of the flip block 21 is fixedly connected with a slide block 24, and the slide block 24 is slidably connected to the surface of the arc-shaped slide bar 23;

[0099] A first spring 25, two ends of which are fixedly connected to the sliding block 24 and the arc groove 22 respectively;

[0100] Specifically, by setting the arc groove 22, the flip block 21 can be rotated at a specified angle, thereby limiting the rotation angle of the injection head, and by setting the first spring 25, when the I-shaped pushing frame 26 cancels the push on the flip block 21, the first spring 25 resets the flip block 21, resets the injection head, and makes the injection head face the specified position.

[0101] During implementation, the second elastic connecting member includes:

[0102] A plurality of sliding rods 27, wherein the plurality of sliding rods 27 are fixedly connected in array to the outer side wall of the sliding frame 18, and the I-shaped pushing frame 26 is slidably connected to the surface of the sliding rods 27;

[0103] A second spring 45, both ends of which are fixedly connected to the sliding frame 18 and the I-shaped pushing frame 26;

[0104] Specifically, when the driving rod 28 is no longer in contact with the protrusion 30 , the I-shaped pushing frame 26 is moved downward and reset under the action of the second spring 45 .

[0107] The expansion bag 35 is fixedly connected to the inner wall of the injection hole 34. The expansion bag 35 expands and contracts according to the rotation angle of the shell 32 to adjust the diameter of the injection hole 34, thereby adjusting the injection speed of the high-temperature gas so that the high-temperature gas can fully contact the inner wall of the capsule 16;

[0108] Specifically, by providing an expansion bag 35, the shell 32 rotates, causing the injection hole 34 to rotate from vertical downward to horizontal. At this time, the distance between the injection port and the inner wall of the capsule 16 increases. The expansion bag 35 reduces the diameter of the injection hole 34, thereby increasing the injection speed of the high-temperature gas, so that the high-temperature gas can fully contact the inner wall of the capsule 16. On the contrary, in the process of the injection hole 34 rotating from the horizontal direction to the vertical direction, the expansion bag 35 increases the diameter of the injection hole 34, thereby reducing the injection speed and increasing the injection range, which is beneficial to fully heating the capsule 16 and improving the tire production quality.

[0112] Specifically, by setting the piston rod 38 and the hollow plate 33, during the rotation of the shell 32, the second connecting pin 39 slides along the arc-shaped driving groove 37. Driven by the arc-shaped driving groove 37, the piston rod 38 rotates along the shell 32 as the shell 32 rotates, and the air pressure in the hollow plate 33 is adjusted in turn, thereby adjusting the expansion amount of the expansion airbag 35.

[0118] Specifically, a vortex hose 40 is provided to inject high-temperature gas into the shell 32.

[0130] The working principle of the present invention is as follows: after the mold assembly clamps the tire body 9 to a limited position, high-temperature gas is injected into the capsule 16 through the injection head. With the injection of the high-temperature gas, the capsule 16 begins to expand. During the expansion of the capsule 16, the first rotary drive assembly is first started to rotate the rotary disk 13, so that the first connecting pin 19 slides along the arc-shaped inclined groove 1201. Driven by the arc-shaped inclined groove 1201, the first connecting pin 19 slides along the straight groove 1301, so that the sliding frame 18 extends outward from the sliding shell 17, so that the injection head is close to the inner wall of the capsule 16, thereby reducing the distance between the injection head and the inner wall of the capsule 16, so that the high-temperature gas injected by the injection head can quickly contact the inner wall of the capsule 16, which is conducive to quickly heating up the inner wall of the capsule 16;

[0131] After the sliding frame 18 is extended, the second rotary drive mechanism is started to rotate the rotating shell 12. Under the connection of the first connecting pin 19, the rotating disk 13 is rotated, and the sliding frame 18 drives the injection head to rotate, so that the injection head uniformly injects the high-temperature gas onto the inner wall of the capsule 16, which is conducive to making the temperature distribution in the capsule 16 more uniform, thereby facilitating improving the production quality of the tire body 9;

[0132] In the process of the sliding frame 18 driving the injection head to rotate, the driving rod 28 moves along the top of the annular driving plate 29 and continuously passes through the protrusion 30. Under the push of the protrusion 30, the I-shaped push frame 26 moves up and down reciprocatingly. In the process of the I-shaped push frame 26 moving up and down, the flip block 21 is pushed to flip, so that the injection head is flipped, so as to adjust the injection angle of the injection head, so that the high-temperature gas can contact the side wall at different positions of the capsule 16, further making the temperature distribution of the inner wall of the capsule 16 uniform, which is beneficial to improve the production quality of the tire body 9;

[0133] After the tire body 9 is vulcanized, the rotating shell 12 stops rotating, and then the rotating disk 13 is rotated and reset through the first rotating drive mechanism. Driven by the arc-shaped inclined groove 1201, the sliding frame 18 drives the injection head to retract into the sliding shell 17 to facilitate the contraction of the capsule 16.

[0134] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
