Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, specifically to a vulcanizing machine. Background Technology

[0002] In traditional tire vulcanization processes, a tire mold and a bladder work together to shape the tire blank. In existing vulcanizing machines, the upper and lower edges of the bladder are held by upper and lower clamps, respectively. The upper clamp is mounted on the central rod of a central mechanism, and the lower clamp is mounted on a ring seat. Driven by the central mechanism, the bladder performs the vulcanization action. During the tire vulcanization process, a high-temperature fluid needs to be continuously supplied into the bladder to provide the necessary temperature and pressure for vulcanization. The bladder expands, compresses, and heats the tire blank, performing the shaping and vulcanization process.

[0003] The ring seat is equipped with a flow channel for high-temperature fluid to enter and exit the capsule. When the high-temperature fluid flows through the ring seat, it will transfer heat to the ring seat. The ring seat is in direct contact with the lower clamp. The high temperature of the ring seat will transfer heat to the lower clamp of the capsule, causing the temperature of the lower clamp of the capsule to be too high. The lower clamp of the capsule is in direct contact with the lower edge of the capsule, resulting in the temperature of the lower edge of the capsule being too high, which affects the service life of the capsule. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a vulcanizing machine that can effectively reduce the heat transfer from the ring seat to the lower edge of the capsule, thereby extending the service life of the capsule.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a vulcanizing machine, including a capsule, a central mechanism, a lower capsule clamp, and an upper capsule clamp. The central mechanism includes a ring seat and a central rod. The central rod is located in the central hole of the ring seat and can move up and down relative to the ring seat. The upper capsule clamp is disposed on the central rod, and the lower capsule clamp is disposed on the ring seat. The lower capsule clamp and the upper capsule clamp respectively clamp the lower and upper edges of the capsule. The ring seat has a main input channel and a main output channel for inputting and outputting high-temperature fluid into and out of the capsule. The ring seat has a heat insulation component, which includes a second heat insulation sheet. The upper end face of the ring seat has a downwardly extending second heat insulation groove, which is distributed radially outside the main input channel and the main output channel. The second heat insulation sheet is located inside the second heat insulation groove.

[0006] As a preferred technical solution, the upper end of the second heat insulation groove is connected to the first heat insulation groove, and the width of the first heat insulation groove is greater than that of the second heat insulation groove. The heat insulation component further includes a first heat insulation sheet, which is located within the first heat insulation groove.

[0007] As a preferred technical solution, the second heat insulation groove is located in the middle of the bottom of the first heat insulation groove in the radial direction.

[0008] As a preferred technical solution, the depth of the second heat insulation groove is greater than that of the first heat insulation groove.

[0009] As a preferred technical solution, both the first heat insulation groove and the second heat insulation groove are annular.

[0010] As a preferred technical solution, the ring seat is provided with a first shell and a second shell from bottom to top; The second housing has a distribution cavity, and gas distribution holes are evenly distributed on the second housing, connecting the distribution cavity and the inner cavity of the capsule; The first housing has an input cavity and an output cavity; the input cavity is connected to the distribution cavity through an input communication channel, and the first housing has an output communication channel connecting the inner cavity of the capsule and the output cavity; The main input channel is connected to the input cavity; the main output channel is connected to the output cavity.

[0011] As a preferred technical solution, both the input cavity and the output cavity are annular, and the input cavity is located radially outside the output cavity.

[0012] As a preferred technical solution, a heating element is provided in the input cavity. The heating element is located between the input communication channel and the main input channel. Gas flowing into the input cavity from the main input channel flows through the heating element and then flows out from the input communication channel.

[0013] As a preferred technical solution, the distribution cavity is equipped with a turbulence-inducing element.

[0014] As a preferred technical solution, a bushing is rotatably installed in the central hole of the ring seat, and the bushing is sleeved on the outside of the central rod; The upper end of the bushing extends into the distribution cavity and is fixedly connected to the turbulence element, rotating synchronously; the lower end is located on the lower side of the ring seat and is connected to a driving element.

[0015] The beneficial effects of this utility model are as follows: The ring seat of the vulcanizing machine is equipped with heat insulation components. These components are distributed on the outer edge of the ring seat. Especially when they are arranged in a ring shape, they can form a heat insulation area between the lower clamp of the capsule and the inside of the ring seat, reducing the transfer of heat from the ring seat to the lower clamp of the capsule. This effectively prevents the internal temperature from being transferred to the edge of the capsule, thus extending the service life of the capsule.

[0016] The heat insulation components also make it possible to install heating elements on the ring seat, which means that the temperature inside the capsule can be more controllable and the control precision can be improved while taking into account the capsule's service life; the turbulence elements can improve the uniformity of temperature distribution inside the capsule and improve the vulcanization quality.

Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to Figures 1-3 This invention provides an embodiment of a vulcanizing machine, comprising a capsule 1, a central mechanism, a lower capsule clamp 2, and an upper capsule clamp 14. The central mechanism includes a ring seat 3 and a central rod 8, wherein the ring seat 3 has a central hole, and the central rod 8 is located within the central hole and can move up and down relative to the ring seat 3, forming a dynamic seal. The upper capsule clamp 14 is mounted on the central rod 8 and moves up and down under the drive of the central rod 8. The lower capsule clamp 2 is mounted on the ring seat 3, and the lower capsule clamp 2 and the upper capsule clamp 14 respectively clamp the lower and upper edges of the capsule 1, positioning and supporting the capsule 1 during the tire vulcanization process. It is understood that the central mechanism also includes a drive mechanism for driving the central rod 8 and the ring seat 3 to move up and down. This application does not improve the drive mechanism, and it will not be described in detail here.

[0021] A first housing 10 and a second housing 11 are sequentially arranged on the upper side of the ring seat 3. The first housing 10 and the second housing 11 are located inside the capsule 1, with the first housing 10 positioned between the ring seat 3 and the second housing 11, and the three are fixedly connected as a single unit. The second housing 11 has a distribution cavity 21, and gas distribution holes 22 are evenly distributed on the second housing 11, penetrating the second housing 11 and connecting the distribution cavity 11 with the inner cavity of the capsule 1. The first housing 10 has an input cavity 15 and an output cavity 20; preferably, both the input cavity 15 and the output cavity 20 are annular, with the input cavity 15 located radially outside the output cavity 20. The input cavity 15 is connected to the distribution cavity 21 through an input communication channel 16, and an output communication channel 17 is provided on the radially outer wall of the first housing 10, which connects the inner cavity of the capsule 1 with the output cavity 20.

[0022] The ring seat 3 is equipped with a main input channel 9 and a main output channel 4. The main input channel 9 is connected to the input chamber 15. The high-temperature gas supplied by the circulating gas supply equipment enters the input chamber 15 through the input connecting channel 9, flows through the input connecting channel 16, the distribution chamber 21, and the gas distribution hole 22, and finally enters the inner cavity of the capsule 1. During vulcanization, it provides a stable high-temperature and high-pressure environment for the capsule 1. The main output channel 4 is connected to the output chamber 20. The gas in the capsule 1 after heat exchange enters the output chamber 20 through the output connecting channel 17, and finally flows back to the circulating gas supply equipment through the main output channel 4. Optionally, the number of input connecting channels 16 and output connecting channels 17 is not limited to one; two or more can be set in the circumferential direction as needed.

[0023] Furthermore, a heating element 13 is provided inside the input cavity 15. The heating element 13 is located between the input communication channel 16 and the main input channel 9. The gas flowing into the input cavity 15 from the main input channel 9 is heated by the heating element 13 and then flows out from the input communication channel 16, which can further increase the temperature of the gas entering the capsule 1, which is beneficial for controlling the gas to be stably maintained within a certain range and has high control precision. The heating element 13 can be a heating device such as an electric heating wire. In the gas flow direction, the heating element 13 is set in any region between the outlet of the main input channel 9 and the inlet of the input communication channel 16, preferably in the middle region between the outlet of the main input channel 9 and the inlet of the input communication channel 16, so as to better airflow uniformity.

[0024] Optionally, a baffle element 12 is provided in the distribution cavity 21, which can be a baffle fan. The baffle fan can rotate under the action of airflow. Preferably, the rotation of the baffle element 12 is controllable, that is, the baffle element 12 is driven by a drive element 6. Exemplarily, a bushing 5 is rotatably installed in the central hole of the ring seat 3. The bushing 5 is sleeved on the outside of the central rod 8 and forms a dynamic seal with the inner wall of the central hole and the outer wall of the central rod 8. The upper end of the bushing 5 extends into the distribution cavity 21 and is fixedly connected to the baffle element 12, rotating synchronously; the lower end is located on the lower side of the ring seat 3 and is driven by the drive element 6. Specifically, the drive element 6 can be a motor, etc., and the frame 7 supports and installs the ring seat 3 and the drive element 6.

[0025] The input cavity 15 is annular, and the heating element 13 is also annular. Gas flowing into the input cavity 15 through the autonomous input channel 9 diffuses within the input cavity 15, initially dispersing and heating the airflow. Multiple input connecting channels 16 are provided, evenly distributed circumferentially, which can improve the uniformity of airflow distribution. The turbulence element 12 further improves the dispersion of airflow, ensuring the pressure consistency of gas within the capsule 1. The output cavity 20 is annular, and multiple output connecting channels 17 are evenly distributed circumferentially within the output cavity 20, serving as a converging channel.

[0026] To prevent the high temperature of the ring seat 3 from affecting the service life of the capsule 1, the ring seat 3 is equipped with a heat insulation component to block or reduce the transfer of heat from the ring seat 3 to the lower capsule clamp 2. The heat insulation component includes a first heat insulation sheet 18 and a second heat insulation sheet 19; wherein, a first heat insulation groove 24 is provided at the outer edge of the upper end face of the ring seat 3, and a second heat insulation groove 23 extending axially is provided at the bottom of the first heat insulation groove 24. Multiple first heat insulation grooves 24 and second heat insulation grooves 23 can be provided and evenly distributed in the circumferential direction; preferably, they are annular. The first heat insulation sheet 18 is located in the first heat insulation groove 24, and the second heat insulation sheet 19 is located in the second heat insulation groove 23. The first heat insulation sheet 18 and the second heat insulation sheet 19 together form a heat insulation layer between the main body of the ring seat 3 and the lower capsule clamp 2. In particular, when the first heat insulation groove 24 and the second heat insulation groove 23 are annular, the heat insulation component surrounds the radially outer side of the main input channel 9 and the main output channel 4, forming an annular heat insulation zone, reducing the influence of the heating element 13 and high-temperature gas on the lower clamp edge of the capsule 1.

[0027] Preferably, the first heat insulation groove 24 and the second heat insulation groove 23 are located near the radial outer side of the ring seat 3, providing ample space for the arrangement of the main input channel 9 and the main output channel 4. The width of the first heat insulation groove 24 is greater than the width of the second heat insulation groove 23, thereby forming a heat insulation zone with a larger radial dimension at the upper end face of the ring seat 3. The second heat insulation groove 23 is located in the middle of the bottom of the first heat insulation groove 24 in the radial direction, which facilitates processing. The depth of the second heat insulation groove 23 is greater than that of the first heat insulation groove 24, so that the second heat insulation sheet 19 can extend a certain length in the axial direction of the ring seat 3 to form an effective and as large as possible heat insulation zone.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
