Description

Technical Field

[0001] The invention relates to the technical field of rubber vulcanizing equipment, in particular to a tire vulcanizing machine. Background Art

[0002] In industrial production, vulcanization is usually used to increase the overall hardness of certain materials. In the tire vulcanization process, tire vulcanization usually refers to the vulcanization of the outer tire, specifically the vulcanization using a model pressurization method. The tire material is usually plastic rubber, which has viscoelasticity before vulcanization, is easy to deform, has low strength, and has no use value. Through the vulcanization process, the plastic rubber is solidified and turned into a highly elastic rubber with commercial value.

[0003] Conventional tire vulcanization processes use a combination of saturated steam and nitrogen. Specifically, a green tire is placed between a sealed vulcanization bladder and a vulcanization mold, saturated steam is introduced into the vulcanization bladder to heat the vulcanization bladder and the vulcanization mold, and the heat required for vulcanization is provided to the green tire. High-pressure nitrogen is then introduced into the vulcanization bladder to provide the pressure required for vulcanization. The vulcanization bladder expands and squeezes the green tire, and the vulcanizer is used to shape and vulcanize the green tire, which can improve the strength of the tire. However, steam will condense when it is cooled, and the condensed water will accumulate under the vulcanization bladder, resulting in a large temperature difference between the upper and lower parts of the vulcanization bladder, which in turn causes the tire to have the defect of incomplete vulcanization. In addition, the steam pipeline will take up a large space.

[0004] In order to solve the above problems, the prior art provides a tire vulcanizer with an electric vulcanizing device as the core; when the tire needs to be vulcanized, an external medium source supplies a gas medium (such as an inert gas such as nitrogen) to the vulcanizing bladder of the tire vulcanizer, so that the vulcanizing bladder expands and squeezes the tire from the inside; the gas medium is heated by a heater arranged inside the vulcanizing bladder; however, some tires need to be cooled during the vulcanization process to prevent the internal heating time from being too long, causing the inner side wall of the tire to be over-vulcanized and causing the tire to be scrapped. When the cooling medium (usually water) comes into contact with the heater inside the vulcanizing bladder, the service life of the heater is easily reduced, and there are certain safety hazards.

[0005] Therefore, developing and designing a tire vulcanizer that is highly safe, does not reduce the service life of the heater, can conveniently realize the two functions of heating and cooling, and has a larger scope of application is a problem that needs to be solved urgently at this stage.

[0056] Please refer to Figure 1-Figure 3 , the specific working mode of the present invention is as follows:

[0057] When vulcanizing the tire, the green tire is loaded onto the outer side of the vulcanizing bladder 6, and the vulcanizing mold 1 is closed so that the green tire is clamped in the vulcanizing space between the vulcanizing bladder 6 and the vulcanizing mold 1;

[0058] A gas medium is injected into the vulcanization bladder 6, and the gas medium is heated by the first electric heating element 32. The gas medium heats and pressurizes the green tire from the inside through the vulcanization bladder 6, and the vulcanization mold 1 heats and pressurizes the tire from the outside. At the same time, the stirring member 5 rotates, and a pressure difference is formed under the action of centrifugal force, which promotes the flow of the gas medium and realizes the vulcanization of the tire.

[0059] When cooling is required, the cooling medium flows in the cooling medium channel 4 to cool the heating tube 31, and the agitator 5 rotates to promote the gas medium with a certain temperature to flow through the cooled surface of the heating tube 31, and the heat is transferred from the inside of the vulcanization capsule 6 through the gas medium, the heating tube 31, and the cooling medium in sequence and then brought out; by means of the temperature detection component 8 arranged inside the vulcanization capsule 6, the temperature of the gas medium can be observed in real time, and the circulation speed of the cooling medium can be controlled accordingly, thereby finally achieving the purpose of precise cooling inside the vulcanization capsule 6. Embodiment 2

[0060] Please refer to Figure 4 The main difference between this embodiment and the first embodiment is that an annular channel 43 is provided on the top of the heating tube 31, and the annular channel 43 is respectively connected with the upper end of the inlet channel 41 and the upper end of the outlet channel 42 to form a loop. All cooling media in the inlet channel 41 pass through the annular channel 43 and flow out from the outlet channel 42, so that the flow rate of the cooling medium in the inlet channel 41 and the outlet channel 42 is more uniform, further improving the cooling effect. Embodiment 3

[0061] Please refer to Figure 5 and Figure 6 The main difference between this embodiment and the first embodiment is that: the cooling medium channel 4 is set as one, the inlet channel 41 is linear, and the outlet channel 42 is spiral. The spiral outlet channel 42 can increase the heat exchange area with the gas medium, and make the cooling medium flow through all circumferential positions of the heating tube 31 before flowing out, so as to maximize the utilization rate of the cooling medium and improve the cooling effect. Embodiment 4

[0062] Please refer to Figure 7 and Figure 8 The main difference between this embodiment and the first embodiment is that the cooling medium channel 4 is nested inside the first electric heating element 32. At this time, the first electric heating element 32 adopts electromagnetic heating. Accordingly, the first electric heating element 32 is set as a hollow copper tube 33, the heating tube 31 is set as a ferromagnetic material, and there is a gap between the copper tube 33 and the heating tube 31. Specifically, a heat insulation pad can be set between the copper tube 33 and the heating tube 31; a high-frequency high-voltage current is passed through the copper tube 33 to generate an alternating magnetic field, which can increase the temperature of the heating tube 31 and achieve heating of the gas medium; at the same time, a cooling medium channel 4 is formed inside the copper tube 33. When cooling is required, the copper tube 33 is powered off and the cooling medium is passed, so that the heat of the gas medium can be effectively absorbed; preferably, a plurality of through grooves 10 are opened at the position of the heating tube 31 facing the copper tube 33. When cooling is required, a part of the gas medium directly exchanges heat with the copper tube 33 through the through grooves 10, further improving the temperature regulation efficiency of the vulcanization cavity 11.

[0063] It should be noted that an insulating structure should be provided between the copper tube 33 and the heating tube 31. For example, an insulating layer (not shown in the drawings) can be provided on the outer wall of the copper tube 33 to avoid leakage while ensuring that the positions of the copper tube 33 and the heating tube 31 are relatively fixed. In addition, an insulating layer (not shown in the drawings) can also be provided on the inner wall of the copper tube 33 to avoid the safety hazards caused by the power supply of the cooling medium, or the cooling medium can also be selected as a non-conductive medium, such as thermal oil, pure water, etc.
