Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to an electrically heated tire vulcanizing device. Background Technology

[0002] Currently, the gas agitation device inside the capsule is passively rotated by the gas blowing inside the heater. During the rotation of the agitation device, the heated gas can be stirred up to ensure the uniformity of temperature inside the capsule. However, the gas agitation device often gets stuck due to the limited gas thrust. Since the gas thrust alone may not be enough to make the gas agitation device rotate, it will affect the uniformity of temperature.

[0003] Although there are technologies that use motors to drive gas stirring devices to enhance the flow of internal heated gas, most of these devices are located below the heating device. The stirring device blows the heat generated by the heating device upwards, which has a relatively small effect on stirring the heated gas. The temperature in the direction of the blowing of the stirring device is always the highest, which still causes uneven temperature inside the capsule.

[0004] In view of the problems existing in the prior art, this utility model designs and manufactures an electrically heated tire vulcanizing device to overcome the above defects. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides an electrically heated tire vulcanizing device that can make the temperature more uniform throughout the capsule.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electrically heated tire vulcanizing device, comprising a vulcanizing mold, wherein the vulcanizing mold is provided with a vulcanizing chamber for forming the tire, and a vulcanizing capsule is provided in the vulcanizing chamber; The vulcanization chamber is provided with a ring seat, and a rotating sleeve is provided at the center of the ring seat. A stirring blade is connected to the rotating sleeve located in the vulcanization capsule, and a driving device for driving the rotating sleeve to rotate is connected to the rotating sleeve located outside the vulcanization capsule. A heater is provided on the ring seat, and a closed cover is provided above the heater. The stirring blade is arranged above the closed cover. Several air inlets are provided on the top circumference of the closed cover, and the airflow ejected from the air inlets is directed toward the stirring blade. A protective cover is provided above the stirring blade, and several dispersion holes are evenly distributed on the top and side walls of the protective cover.

[0007] Preferably, the enclosure is radially provided with two layers, and the two layers of the enclosure are respectively configured as an inner enclosure cavity and an outer enclosure cavity that are isolated from each other; The heater is disposed in the inner closed cavity, the air inlet is disposed at the top of the inner closed cavity, and the ring seat is also provided with a medium inlet, which is disposed below the corresponding inner closed cavity; The outer sealed cavity has several air outlets on its sidewalls, and the ring seat also has a medium outlet located below the corresponding outer sealed cavity.

[0008] Preferably, the air inlet is positioned at an angle to the axial direction of the ring seat and faces upwards towards the vulcanizing capsule.

[0009] Preferably, the air outlet is oriented towards the medium outlet.

[0010] Preferably, the heater is annular, and the air inlet is located at the top of the inner closed cavity outside the annular heater; The medium inlet is located below the inner closed cavity inside the annular heater.

[0011] Preferably, it also includes a center rod that can be raised and lowered, and an upper clamping ring is installed on the top of the center rod. The center rod can clamp the upper end of the vulcanizing capsule through the upper clamping ring in conjunction with the vulcanizing mold. The central rod can be raised and lowered within the rotating sleeve.

[0012] Preferably, the rotating sleeve and the ring seat are rotatably connected by a bearing.

[0013] Preferably, the enclosure is detachably mounted on the ring seat; The protective cover is detachably mounted on top of the enclosure.

[0014] Preferably, the top center of the enclosure is provided with a first through hole, the diameter of which is larger than the diameter of the rotating sleeve; The protective cover has a second through hole at the top center, and the diameter of the second through hole is larger than the diameter of the center rod.

[0015] Preferably, the protective cover is made of metal.

[0016] The advantages of this utility model are: 1. In this invention, the stirring blades are positioned above the heater. The heated vulcanizing medium is directed toward the stirring blades through the air inlet. The stirring blades can stir and disperse the heated vulcanizing medium. Due to the protective cover and the dispersion holes, the heated vulcanizing medium inside the protective cover is divided into multiple fine streams as it diffuses outward. The fine streams are more evenly dispersed due to the stirring effect of the stirring blades.

[0017] 2. The stirring blades of this utility model are set above the heater. The active operation of the stirring blades can not only prevent uneven temperature inside the vulcanizing capsule caused by the stirring blades getting stuck, but also find the optimal speed for temperature uniformity inside the vulcanizing capsule by adjusting the speed of the stirring blades, thus ensuring the uniformity of temperature inside the vulcanizing capsule.

[0018] 3. The protective cover of this utility model is placed above the stirring blades. When the heated vulcanizing medium passes through the protective cover, it will raise the temperature of the protective cover itself to a certain extent. The temperature increase of the protective cover will also become a heat source. The addition of this heat source will expand the heating area, thereby making the heating of the vulcanizing medium more uniform. Moreover, since the protective cover is made of metal, the specific heat capacity of metal is higher than that of the heated vulcanizing medium. Each time the vulcanizing product is replaced and reheated, the temperature of the protective cover is higher than the temperature inside the vulcanizing capsule. At this time, the protective cover, as a heat source, can more efficiently improve the vulcanization efficiency.

[0019] 4. The sealing cover of this utility model adopts a two-layer structure. The vulcanizing medium enters the inner sealing cavity through the medium inlet at the bottom of the inner sealing cavity. After being heated in the inner sealing cavity, it diffuses outward to vulcanize the rubber. Then, the vulcanizing medium enters the outer sealing cavity through the air outlet connected to the outer sealing cavity, and is discharged from the medium outlet connected to the bottom of the outer sealing cavity, forming a complete cycle. Throughout the process, the vulcanizing medium during heating is isolated from the vulcanizing medium that needs to be discharged, ensuring the full utilization of the heat energy of the heated vulcanizing medium.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 3As shown, an electrically heated tire vulcanizing device includes a vulcanizing mold 1, which is a hollow, openable structure. The vulcanizing mold 1 has a vulcanizing chamber for forming the tire inside, and a vulcanizing capsule 2 is provided in the vulcanizing chamber.

[0024] The vulcanization chamber is equipped with a ring seat 3, which is located below the vulcanization capsule 2. The ring seat 3 is generally equipped with a lower clamping ring, which together with the vulcanization mold 1 clamps the lower end of the vulcanization capsule 2.

[0025] A rotating sleeve 6 is located at the center of the ring seat 3. The rotating sleeve 6 is rotatably connected to the ring seat 3 via a bearing. A stirring blade 5 is connected to the rotating sleeve 6 located inside the vulcanizing capsule 2. A drive device 7, specifically a drive motor, is connected to the rotating sleeve 6 located outside the vulcanizing capsule 2. The system also includes a liftable central rod 10. An upper clamping ring 11 is installed at the top of the central rod 10. The central rod 10 can clamp the upper end of the vulcanizing capsule 2 through the upper clamping ring 11 in conjunction with the vulcanizing mold 1. The central rod 10 can move up and down within the rotating sleeve 6.

[0026] A heater 4 is provided on the ring seat 3, and a closed cover 8 is provided above the heater 4. The stirring blade 5 is located above the closed cover 8. Several air inlets 14 are provided on the top circumference of the closed cover 8. The airflow ejected from the air inlets 14 is directed toward the stirring blade 5. A protective cover 9 is provided above the stirring blade 5. Several dispersion holes 91 are evenly distributed on the top and side walls of the protective cover 9.

[0027] This invention places the stirring blade 5 above the heater 4. The heated vulcanizing medium is directed toward the stirring blade 5 through the air inlet 14. The stirring blade 5 can stir and disperse the heated vulcanizing medium. Due to the setting of the protective cover 9 and the dispersion hole 91, the heated vulcanizing medium inside the protective cover 9 is divided into multiple fine medium streams when it diffuses outward. The fine medium streams are more evenly dispersed due to the stirring effect of the stirring blade 5.

[0028] Moreover, the stirring blade 5 is positioned above the heater 4. The active operation of the stirring blade 5 can prevent uneven temperature inside the vulcanizing capsule 2 caused by the stirring blade 5 getting stuck. It can also find the optimal speed for temperature uniformity inside the vulcanizing capsule 2 by adjusting the speed of the stirring blade 5, thus ensuring the uniformity of temperature inside the vulcanizing capsule 2.

[0029] The present invention has two radially arranged sealing covers 8, which are respectively configured as an inner sealing cavity 12 and an outer sealing cavity 13 isolated from each other. The heater 4 is arranged in the inner sealing cavity 12, and the air inlet 14 is arranged at the top of the inner sealing cavity 12. The ring seat 3 is also provided with a medium inlet 16, which is located below the corresponding inner sealing cavity 12. The side wall of the outer sealing cavity 13 is provided with several air outlets 15, and the ring seat 3 is also provided with a medium outlet 17, which is located below the corresponding outer sealing cavity 13.

[0030] The vulcanizing medium enters the inner sealed cavity 12 through the medium inlet 16 at the bottom of the inner sealed cavity 12. After being heated in the inner sealed cavity 12, it diffuses outward to vulcanize the rubber. Then, the vulcanizing medium enters the outer sealed cavity 13 through the air outlet connected to the outer sealed cavity 13, and is discharged through the medium outlet 17 connected to the bottom of the outer sealed cavity 13, forming a complete cycle. Throughout the process, the vulcanizing medium during heating is isolated from the vulcanizing medium that needs to be discharged, ensuring the full utilization of the heat energy of the heated vulcanizing medium.

[0031] The air inlet 14 is angled to the axis of the ring seat 3 and faces upwards towards the vulcanizing capsule 2. After being stirred by the stirring blades 5, the heated vulcanizing medium can be quickly transferred to the vulcanizing capsule 2. The air outlet 15 faces the medium outlet 17, ensuring that after the vulcanizing medium enters the outer sealed cavity 13 through the air outlet 15, it can be quickly discharged from the medium outlet 17 at the bottom of the outer sealed cavity 13.

[0032] The heater 4 is designed as an annular shape, with the air inlet 14 located at the top of the inner closed cavity 12 outside the annular heater 4, and the medium inlet 16 located below the inner closed cavity 12 inside the annular heater 4. The heater 4 is located on the flow channel of the vulcanizing medium, so that the vulcanizing medium is heated by the heater 4 first and then discharged through the air inlet 14, ensuring the temperature rise of the vulcanizing medium.

[0033] The enclosed cover 8 is preferably detachably mounted on the ring seat 3, thereby facilitating the installation of the heater 4. The protective cover 9 is detachably mounted on the top of the enclosed cover 8, thereby facilitating the installation of the stirring blade 5. The top center of the enclosed cover 8 has a first through hole 81, the diameter of which is larger than the diameter of the rotating sleeve 6. The top center of the protective cover 9 has a second through hole 92, the diameter of which is larger than the diameter of the central rod 10.

[0034] The protective cover 9 of this utility model is preferably made of metal. The protective cover 9 covers the stirring blade 5. When the heated vulcanizing medium passes through the protective cover 9, it will raise the temperature of the protective cover 9 itself to a certain extent. The temperature increase of the protective cover 9 will also become a heat source. The addition of this heat source will expand the heating area, thereby making the heating of the vulcanizing medium more uniform. Moreover, since the protective cover 9 is made of metal, the specific heat capacity of metal is higher than that of the heated vulcanizing medium. Each time the vulcanizing product is replaced and reheated, the temperature of the protective cover 9 is higher than the temperature inside the vulcanizing capsule 2. At this time, the protective cover 9, as a heat source, can more efficiently improve the vulcanization efficiency.

[0035] The specific vulcanization process of this utility model is as follows: The vulcanizing medium is powered by external equipment and enters the inner closed cavity 12 through the medium inlet 16 on the ring seat 3. After being heated by the heater 4 in the inner closed cavity 12, it enters the area below the stirring blade 5 through the air inlet 14. The rotating stirring blade 5 stirs and disperses the heated vulcanizing medium. The air outlet on the protective cover 9 divides the heated vulcanizing medium into multiple fine medium streams, thereby uniformly heating the inside of the vulcanizing capsule 2. After circulation, the vulcanizing medium enters the outer sealed cavity 13 through the vent 15 and is then discharged from the medium outlet 17 at the bottom of the outer sealed cavity 13.

[0036] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
