Description

Technical Field

[0001] The present invention relates to the technical field of tire vulcanization equipment, and in particular to a two-station new energy vulcanization system capable of performing series or parallel vulcanization operations and its uses. Background Art

[0002] When the applicant was continuously conducting in-depth research and development on a new energy vulcanization system using pure nitrogen as the vulcanization medium, it was found that for a two-station vulcanization system, when the vulcanization media of the two vulcanization stations are connected in series (i.e., the vulcanization medium circulates between the two vulcanization stations) for vulcanization operations, and when the vulcanization media of the two vulcanization stations are connected in parallel (i.e., the vulcanization medium only circulates within its respective vulcanization station) to enable the vulcanization media of each vulcanization station to perform vulcanization operations of their respective vulcanization stations independently, the series and parallel vulcanization modes of the vulcanization medium of the two-station vulcanization system each have advantages. This is mainly reflected in: when the vulcanization media of the two-station vulcanization system are connected in series, since the high-temperature nitrogen in the circulating vulcanization pipeline is not shunted, the temperature rise is faster; when the vulcanization media of the two-station vulcanization system are connected in parallel, since the pressure of the two vulcanization stations can be controlled separately, the pressure difference between the two vulcanization stations can be controlled within a small range, so the pressure control within the two vulcanization stations is more accurate and stable.

[0003] In addition, according to the market feedback information, some customers prefer the two-station vulcanization system in series mode, while some customers value the two-station vulcanization system in parallel mode more. However, at present, no tire vulcanization system using pure nitrogen as the vulcanization medium that can achieve free switching between series and parallel of the vulcanization medium has been found. Therefore, the applicant believes that it is urgent to develop a two-station new energy vulcanization system capable of performing series or parallel vulcanization operations to meet the potential market demand.

When the balance valve F1A, the seventh switching valve V7, the first switching valve V1, the second switching valve V2, the fifth switching valve V5, and the thirteenth switching valve V13 are in the air guiding state and other switching valves are disconnected. At this time, the low-pressure nitrogen gas in the gas source 20 enters the second capsule 12B along the low-pressure gas source pipe line 21, the first low-pressure charging pipe line 71A, the first capsule inlet pipe line 41A, the first capsule 12A, the first capsule outlet pipe line 42A, the series-parallel switching pipe line 51, the second circulation outlet pipe line 31B, and the second capsule inlet pipe line 41B air guiding path to realize the inflation and shaping of the first capsule 12A and the second capsule 12B.

[0036] Figure 3It is a schematic diagram of the flow of vulcanization medium when the dual-station vulcanization system of the present invention imports low-pressure vulcanization medium in parallel mode. When the first bladder 12A is inflated with low pressure alone, the balance valve F1A, the seventh switching valve V7, and the first switching valve V1 are in the air guiding state, and other switching valves are disconnected. When the second bladder 12B is inflated with low pressure alone, the balance valve F1B, the twelfth switching valve V12, and the thirteenth switching valve V13 are in the air guiding state, and other switching valves are disconnected; when the first bladder 12A and the second bladder 12B are inflated with low pressure simultaneously, the balance valve F1A, the seventh switching valve V7, the first switching valve V1, the fourth switching valve V4, and the thirteenth switching valve V13 are in the air guiding state, and other switching valves are disconnected.

When the nitrogen vulcanization medium in the first bladder 12A and the second bladder 12B meets the tire vulcanization conditions of high temperature and high pressure, the circulation pump 30 cyclically inhales and discharges the nitrogen vulcanization medium to realize the cyclic flow of the vulcanization medium. In the series mode of the dual-station vulcanization system, when the third switching valve V3, the first switching valve V1, the second switching valve V2, the fifth switching valve V5, the thirteenth switching valve V13, and the fourteenth switching valve V14 are in the air guiding state, and other switching valves are disconnected, at this time, the high-temperature and high-pressure nitrogen vulcanization medium under the action of the circulation pump 30 realizes the cyclic vulcanization path flow from the first circulation outlet pipeline 31A of the circulation pump 30, the first bladder inlet pipeline 41A, the first bladder 12A, the first bladder outlet pipeline 42A, the series-parallel switching pipeline 51, the second circulation outlet pipeline 31B, the second bladder inlet pipeline 41B, the second bladder 12B, the second bladder outlet pipeline 42B, the second circulation inlet pipeline 32B, and the first circulation inlet pipeline 32A to the circulation pump 30, thereby realizing the vulcanization operation of the tires at the first bladder 12A and the second bladder 12B.

Specifically, the nitrogen vulcanization medium flows along the circulation vulcanization path X1 from the first circulation outlet pipeline 31A of the circulation pump 30, the first bladder inlet pipeline 41A, the first bladder 12A, the first bladder outlet pipeline 42A, the first circulation inlet pipeline 32A to the circulation pump 30, thereby realizing the vulcanization operation of the tire at the first bladder 12A. At the same time, since the third switching valve V3, the fourth switching valve V4, the thirteenth switching valve V13 and the fourteenth switching valve V14 are in the air guiding state, at this time, under the action of the circulation pump 30, the high-temperature and high-pressure nitrogen vulcanization medium can simultaneously flow along the circulation vulcanization path Y1 from the first circulation outlet pipeline 31A of the circulation pump 30, the second circulation outlet pipeline 31B, the second bladder inlet pipeline 41B, the second bladder 12B, the second bladder outlet pipeline 42B, the second circulation inlet pipeline 32B, the first circulation inlet pipeline 32A to the circulation pump 30, thereby realizing the vulcanization operation of the tire at the second bladder 12B.

When the vulcanization medium of the first bladder 12A is recovered alone, the second switching valve V2, the sixth switching valve V6, the eleventh switching valve V11, and the ninth switching valve V9 are in the air guiding state, and other switching valves are disconnected. When the vulcanization medium of the second bladder 12B is recovered alone, the fourteenth switching valve V14, the eleventh switching valve V11, and the ninth switching valve V9 are in the air guiding state, and other switching valves are disconnected. When the vulcanization medium of the first bladder 12A and the second bladder 12B are recovered simultaneously, the second switching valve V2, the sixth switching valve V6, the eleventh switching valve V11, the fourteenth switching valve V14 and the ninth switching valve V9 are in the air guiding state, and other switching valves are disconnected.
