Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tire vulcanization equipment, in particular to a double-station new energy vulcanization system capable of single-mode single-action and using pure nitrogen as a vulcanization medium and the use thereof. BACKGROUND

[0002] The existing double-station (i.e., double-mode) tire vulcanization system (or vulcanization machine) can only vulcanize tires of the same size at the same time, that is, two vulcanization stations can only start a certain process at the same time, and after the two vulcanization stations complete the process, they can simultaneously perform the next process. Therefore, if two vulcanization stations are required to vulcanize tires of different sizes at the same time, since the time for each vulcanization process of tires of different sizes is inconsistent or differs greatly, one vulcanization station has to wait for the other vulcanization station, which leads to a waste of energy consumption and tire vulcanization capacity.

[0031] Appendix Figure 1The first embodiment of the new energy vulcanization system is shown in the overall schematic view. Specifically, the outlet end of the circulating pump 60 is provided with a circulating pump exhaust pipeline, and the circulating pump exhaust pipeline is provided with a fifteenth switch valve V15 for controlling the on-off of the circulating pump. The circulating pump exhaust pipeline is in communication with a first circulating gas outlet pipeline 61 A provided with a third switch valve V3 and a second circulating gas outlet pipeline 61B provided with a fourth switch valve V4. The first circulating gas outlet pipeline 61 A is in communication with a first capsule gas inlet pipeline 21 A, and the second circulating gas outlet pipeline 61B is in communication with a second capsule gas inlet pipeline 21B. The inlet end of the circulating pump 60 is provided with a circulating pump gas inlet pipeline, and the circulating pump gas inlet pipeline is in communication with a first circulating gas inlet pipeline 62A provided with a fifth switch valve V5 and a second circulating gas inlet pipeline 62B provided with a sixth switch valve V6.

[0032] Based on the above configuration structure, by cooperating the on-off of the third switch valve V3 and the fourth switch valve V4, and the on-off of the fifth switch valve V5 and the sixth switch valve V6, the first vulcanization station and the second vulcanization station can independently perform tire circulating vulcanization operation, that is, when the first capsule is subjected to circulating vulcanization, other process operations of the second capsule are not affected. Similarly, when the second capsule is subjected to circulating vulcanization, other process operations of the first capsule are not affected. Therefore, the two vulcanization stations in the double-station vulcanization machine can simultaneously perform tire vulcanization operation of the same specification or different specifications, that is, the "single-mode single-action" tire vulcanization operation mode.

[0033] The low-pressure inflation pipeline of the application comprises a first low-pressure inflation pipeline 31A provided with a seventh switch valve V7 for a first vulcanization station, and a second low-pressure inflation pipeline 31B provided with a thirteenth switch valve V13 for a second vulcanization station; the gas source 50 comprises a low-pressure gas source pipeline 51 in communication with the first low-pressure inflation pipeline 31A and the second low-pressure inflation pipeline 31B respectively, one end of the first low-pressure inflation pipeline 31A is in communication with the first capsule gas inlet pipeline 21A, and the other end of the second low-pressure inflation pipeline 31B is in communication with the second capsule gas inlet pipeline 21B. The first capsule and the second capsule are respectively introduced into the low-pressure vulcanizing medium through the two groups of low-pressure inflation pipelines to shape the capsules. Since the first low-pressure inflation pipeline 31A and the second low-pressure inflation pipeline 31B are independently arranged, when the first capsule is introduced into the low-pressure vulcanizing medium, it does not affect the operation of other processes of the second capsule; similarly, when the second capsule is introduced into the low-pressure vulcanizing medium, it also does not affect the operation of other processes of the first capsule. The arrangement of the two groups of low-pressure inflation pipelines can meet the different shaping requirements of the first capsule and the second capsule.

[0034] The high-pressure inflation pipeline 32 of the application is provided with a twelfth switch valve V12.

That is, the high-pressure gas source pipeline 52 is in communication with the first capsule gas inlet pipeline 21A through the high-pressure inflation pipeline 32 and the first circulating gas outlet pipeline 61A, and the high-pressure gas source pipeline 52 is in communication with the second capsule gas inlet pipeline 21B through the high-pressure inflation pipeline 32 and the second circulating gas outlet pipeline 61B.

When the first capsule is introduced into the high-pressure vulcanizing medium, it does not affect the operation of other processes of the second capsule; similarly, when the second capsule is introduced into the high-pressure vulcanizing medium, it also does not affect the operation of other processes of the first capsule.

Through the above configuration, the first capsule and the second capsule can be independently recovered and exhausted of the vulcanizing medium.

[0036] Specifically, the exhaust pipeline 40 comprises a medium recovery pipeline 41 provided with an eighth switch valve V8 and a medium exhaust pipeline 42 provided with a ninth switch valve V9; the gas source 50 further comprises a recovery gas source pipeline 53 and a negative pressure gas source pipeline 54. The medium recovery pipeline 41 is communicated with the recovery gas source pipeline 53, and the medium exhaust pipeline 42 is communicated with the negative pressure gas source pipeline 54. The recovery gas source pipeline 53 in the first vulcanization station is communicated with the first capsule gas outlet pipeline 22A through the medium recovery pipeline 41, the first exhaust pipeline 71, and the second vulcanization station is communicated with the second capsule gas outlet pipeline 22B through the medium recovery pipeline 41, the second exhaust pipeline 72.

Through the above arrangement, the vulcanizing medium in the first capsule and the second capsule can be independently recovered and exhausted, and the high-temperature and high-pressure vulcanizing medium can be introduced into the gas source 50 for reuse. By controlling the on-off of the tenth switch valve V10 and the eleventh switch valve V11, the first vulcanization station and / or the second vulcanization station can be selectively exhausted, that is, when the first capsule is recovered or exhausted of the vulcanizing medium, it does not affect the operation of other processes of the second capsule, and when the second capsule is independently recovered or exhausted of the vulcanizing medium, it does not affect the operation of other processes of the first capsule.

[0037] Further, the application can be provided with an energy storage device 80, one end of the energy storage device 80 is provided with an energy storage outlet pipeline 81, the energy storage outlet pipeline 81 is communicated with the first circulating outlet pipeline 61A and the second circulating outlet pipeline 61B respectively, the other end of the energy storage device 80 is communicated with the high-pressure inflation pipeline 32.

Further reduce the energy consumption required for heating and warming the vulcanizing medium.

[0053] attached Figure 8 to the attached Figure 12 The second embodiment of the present application is a schematic diagram of the flow of vulcanizing medium when the first capsule and / or the second capsule are vulcanized, inflated, circulated, and exhausted. The specific principles are similar to those of the first embodiment, so they will not be described again.

[0054] Preferably, the two embodiments of the present application can further include a series-parallel switching pipeline 91 provided with a fourteenth switch valve V14 for controlling whether the first vulcanization circulation pipeline of the first bladder 12A and the second vulcanization circulation pipeline of the second bladder 12B are arranged in series or in parallel. Specifically, one end of the series-parallel switching pipeline 91 is in communication with the first bladder outlet pipeline on the gas vulcanizing medium outlet side of the second switch valve V2, and the other end of the series-parallel switching pipeline 91 is in communication with the second circulation outlet pipeline between the fourth switch valve and the seventeenth switch valve or the second bladder inlet pipeline, which can be in communication with the vulcanizing medium inlet end of the seventeenth switch valve V17 on the second bladder inlet pipeline 21B. Therefore, when the series-parallel switching pipeline 91 provided with the fourteenth switch valve V14 is in a conductive state, and the fifteenth switch valve V15, the third switch valve V3, the first switch valve V1, the second switch valve V2, the seventeenth switch valve V17 and the sixth switch valve V6 are also in a conductive state, and other switch valves are turned off, the vulcanizing medium discharged from the outlet end of the circulation pump 60 enters the circulation pump 60 through the circulation pump outlet pipeline, the first circulation outlet pipeline 61A, the first bladder inlet pipeline 21A, the first bladder 12A, the first bladder outlet pipeline 22A, the series-parallel switching pipeline 91, the second bladder inlet pipeline 21B, the second bladder 12B, the second bladder outlet pipeline 22B and the second circulation inlet pipeline 62B to complete the vulcanizing medium circulation action. At this time, the first bladder 12A and the second bladder 12B are arranged in series to meet the customer's requirement for rapid vulcanization and temperature rise. When the series-parallel switching pipeline 91 provided with the fourteenth switch valve V14 is in a disconnected state, the vulcanizing medium in the first bladder 12A realizes independent vulcanization operation through the first vulcanization circulation pipeline, and the vulcanizing medium in the second bladder 12B realizes independent vulcanization operation through the second vulcanization circulation pipeline, and the first vulcanization circulation pipeline and the second vulcanization circulation pipeline are independent of each other and do not interfere with each other. In combination with the independent inflation pipeline and the exhaust pipeline of the first bladder 12A and the second bladder 12B, the "single mode single action" vulcanization operation can be realized, that is, the two vulcanization stations in the double-station vulcanization machine can simultaneously perform the same specification or different specification tire vulcanization operation independently of each other.

[0055] It should be noted that in the "single mode single action" mode, when the first bladder and the second bladder are operated in parallel synchronous vulcanization process, that is, the same specification tire vulcanization operation is performed at the same time, the requirement of the customer for high consistency of vulcanization pressure can be met. When the first bladder and the second bladder are operated in parallel asynchronous vulcanization process, that is, different specification tire vulcanization operation is performed through different vulcanization stations, the customer's demand for small batch and multi-specification tire vulcanization can be met.

[0056] In addition, the double-station new energy vulcanization system capable of single mode single action of the present application can be used for vulcanizing various passenger cars, trucks and other vehicle tires.

[0057] In summary, the application provides a new energy vulcanization system with nitrogen as a vulcanization medium, which can be single-mode and single-action. A new vulcanization process is designed to enable two vulcanization stations to perform tire vulcanization operations of the same size or different sizes simultaneously and independently, thereby meeting different customer needs, such as single-mode tire vulcanization, double-mode same-size tire vulcanization, and double-mode different-size tire vulcanization, and effectively improving the use efficiency of the double-station vulcanization machine.
