Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire vulcanization equipment, in particular to a tire vulcanizing machine center mechanism vortex device. BACKGROUND

[0002] At present, as a tire vulcanizing machine, there is a capsule method, which is to supply steam, high-temperature gas (such as inert gas, air, etc.) and other heating and pressurizing media to the inside of the capsule, and through the supply, the capsule is inflated, so that the tire blank is pressed on the mold, thereby the vulcanization of the tire blank is carried out.

[0003] For example, the patent for invention with publication number CN116604859B discloses a tire vulcanizing machine, which comprises a ring seat having a central through hole in the axial direction; a vulcanizing capsule fixed to the ring seat and defining a hollow capsule inner cavity together with the upper part of the ring seat; a rotary drive device converting electric power into rotary power, comprising a stator assembly fixed to the lower part of the ring seat in the axial direction and having a central through hole, a rotor assembly at least partially arranged in the central through hole of the stator assembly, the upper part of the rotor assembly being rotatably arranged in the central through hole of the ring seat; a support cylinder detachably fixed to the lower part of the stator assembly; and a center rod penetrating through the support cylinder and the rotor assembly of the rotary drive device, wherein the center rod and the support cylinder define a first cylindrical space, the center rod and the rotor assembly define a second cylindrical space, and the first cylindrical space and the second cylindrical space jointly form a medium channel, the upper part of the medium channel being in communication with the capsule inner cavity of the vulcanizing capsule.

[0004] For the above-mentioned case, in the process of vulcanizing the tire, high-temperature gas needs to be supplied to the inside of the capsule. However, with the continuous injection of high-temperature gas, the capsule will continuously expand, the internal cavity of the capsule will increase, and because the high-temperature gas directly filled 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, thereby easily leading to uneven heating temperature distribution on the inner surface of the tire, which cannot achieve ideal uniformity. 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.

[0081] Further comprising:

[0082] A turnover block 21 is coaxially fixed with the spray head, and the turnover block 21 is connected with the side wall of the sliding frame 18 through a first elastic connecting piece;

[0087] Specifically, in the prior art, high-temperature gas needs to be supplied to the inside of the capsule 16 during the vulcanization of the tire, however, as the high-temperature gas continues to be injected, the capsule 16 continues to expand, the internal cavity of the capsule 16 increases, and as the high-temperature gas directly injected 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, thereby easily leading to uneven heating temperature distribution on the inner surface of the tire, which cannot achieve ideal uniformity, and uneven temperature will not only affect the consistency of tire vulcanization and product quality, and in serious cases, it can even cause the tire to be scrapped, and the technical solution can solve the above problems, and the specific operation is as follows:

[0088] After the mold assembly clamps and limits the tire body 9, the high-temperature gas is injected into the capsule 16 through the injection head, and as the high-temperature gas is injected, the capsule 16 begins to expand, and in the process of expansion of the capsule 16, the first rotary drive assembly is started first, so that the rotating disc 13 rotates, so that the first connecting pin 19 slides along the arc-shaped chute 1201, and under the drive of the arc-shaped chute 1201, the first connecting pin 19 slides along the straight chute 1301, so that the sliding frame 18 extends outwards 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 sprayed by the injection head can quickly contact the inner wall of the capsule 16, thereby facilitating rapid heating of the inner wall of the capsule 16;

[0089] After the sliding frame 18 extends, the second rotary drive mechanism is started, so that the rotating shell 12 rotates, and under the connecting action of the first connecting pin 19, the rotating disc 13 rotates, and the sliding frame 18 drives the injection head to rotate, so that the injection head uniformly sprays high-temperature gas onto the inner wall of the capsule 16, thereby facilitating more uniform temperature distribution in the capsule 16, thereby facilitating improvement of 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 disc 13 is rotated and reset through the first rotary drive mechanism, and under the drive of the arc-shaped chute 1201, the sliding frame 18 drives the injection head to retract into the sliding shell 17, so as to shrink the capsule 16.

Under the pushing of the protrusion 30, the I-shaped pushing frame 26 moves up and down reciprocatingly. The I-shaped pushing frame 26 moves up and down to flip the turnover block 21 to flip the injection head to adjust the spraying angle of the injection head, so that the high-temperature gas can contact the sidewall at different positions of the capsule 16, further uniform the temperature distribution of the inner wall of the capsule 16, thereby facilitating the improvement of the production quality of the tire body 9.

[0133] After the tire body 9 is vulcanized, the rotating shell 12 is stopped rotating, and then the rotating disc 13 is rotated and reset by the first rotary drive mechanism. Under the drive of the arc-shaped inclined groove 1201, the sliding frame 18 drives the injection head to retract into the sliding shell 17, so as to shrink the capsule 16.

[0134] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application. Various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
