[0041] In order to solve the problem of complex structure of vulcanizer in the prior art, the present invention provides a vulcanizer.

[0042] like Figures 1 to 11The vulcanizer shown in the figure comprises a base body 10, an intermediate column 20, a plurality of edge columns 30, a vulcanizing chamber 40, a tire loading mechanism 50 for loading a tire and a tire unloading mechanism 60 for unloading a tire, a mold adjusting device 70, a mold locking device 80 and a central mechanism 90. The intermediate column 20 and the edge columns 30 are both connected to the base body 10. The intermediate column 20 and the edge columns 30 are arranged in a V-shaped structure, and the edge columns 30 are located at the ends of the V-shaped structure, and the intermediate column 20 is located at the corners of the V-shaped structure; the vulcanizing chamber 40 is located in the V-shaped structure, and the vulcanizing chamber 40 includes an upper main plate 41 and a lower bottom plate 42; the adjacent intermediate columns 20 and the edge columns are arranged in a V-shaped structure. In the column 30, one of the middle column 20 and the edge column 30 is provided with a tire loading mechanism 50, and the other of the middle column 20 and the edge column 30 is provided with a tire unloading mechanism 60; the mold adjusting device 70 is arranged on the upper main board 41, and is movably arranged relative to the base body 10, and can adjust the relative position between the upper main board 41 and the lower bottom plate 42; the mold locking device 80 is arranged between the upper main board 41 and the lower bottom plate 42, and can lock the relative position when the upper main board 41 and the lower bottom plate 42 are buckled; the central mechanism 90 is connected to the base body 10, and at least a part of the central mechanism 90 is located in the vulcanization chamber 40, and provides steam for the vulcanization chamber 40.

[0043] In this embodiment, the middle column 20 and the edge column 30 are arranged in a V-shaped structure, and the tire loading mechanism 50 and the tire unloading mechanism 60 are not provided with separate columns, but are arranged on the middle column 20 or the edge column 30, thereby eliminating the separate supporting structure of the tire loading mechanism 50 and the tire unloading mechanism 60 of the traditional vulcanizer, and integrating the structure and function of the tire loading mechanism 50 and the tire unloading mechanism 60 on the edge column 30 and the middle column 20, so that the middle column 20 and the edge column 30 can not only support the vulcanization chamber 40, but also The tire loading mechanism 50 and the tire unloading mechanism 60 can be supported, thereby simplifying the structure of the vulcanizer, saving the space occupied by the vulcanizer and reducing the cost. At the same time, the vulcanization chamber 40 is arranged in a V-shaped structure, and the mold adjusting device 70, the mold locking device 80, and the central mechanism 90 are arranged around the vulcanization chamber 40, so as to facilitate the mold adjusting device 70, the mold locking device 80, the central mechanism 90, etc. to adjust the mold, lock the mold, provide steam, etc. of the vulcanization chamber 40, thereby facilitating the smooth implementation of the tire vulcanization process, which is conducive to improving work efficiency and saving energy and reducing consumption.

[0044] It should be noted that the up and down direction of this embodiment refers to the arrangement direction of the upper main board 41 and the lower bottom board 42, that is, Figure 1 The up and down directions in .

[0045] like Figure 1 , Figure 2 , Figure 3As shown, in the present embodiment, there are multiple vulcanization chambers 40, multiple tire loading mechanisms 50 and multiple tire unloading mechanisms 60, the tire loading mechanisms 50 are laterally rotatably connected to the edge columns 30, the tire unloading mechanisms 60 are laterally rotatably connected to the middle columns 20, and the tire loading mechanisms 50 matched with different vulcanization chambers 40 are respectively connected to different edge columns 30, and the tire unloading mechanisms 60 matched with different vulcanization chambers 40 are connected to the same middle column 20. In this way, through the reasonable configuration of the tire loading mechanisms 50, the tire unloading mechanisms 60 and the vulcanization chambers 40, the vulcanization operations of multiple tires can be carried out simultaneously, which greatly improves the production efficiency, simplifies the structure of the vulcanizer, and reduces the space occupied by the vulcanizer. In this embodiment, the tire loading mechanism 50 is rotatably arranged on the edge column 30, and the tire unloading mechanism 60 is rotatably arranged on the middle column 20, so that a vulcanization chamber 40 is arranged between the adjacent tire loading mechanisms 50 and tire unloading mechanisms 60, so that the tire loading mechanism 50 and the tire unloading mechanism 60 can conveniently send the tire into the vulcanization chamber 40 and take it out from the vulcanization chamber 40. In this embodiment, the middle column 20 and two edge columns 30 are arranged, and a vulcanization chamber 40 is arranged between each edge column 30 and the middle column 20, so that the present embodiment is provided with two vulcanization chambers 40, and a tire loading mechanism 50 is respectively arranged on each edge column 30, and the tire loading mechanism 50 is arranged on the side of the edge column 30 away from the middle column 20, and two tire unloading mechanisms 60 are arranged on the middle column 20, and the tire unloading mechanisms 60 are arranged on the side of the middle column 20 away from the edge column 30, so that the two vulcanization chambers 40 can work simultaneously, thereby improving the working efficiency of the vulcanizer. Of course, according to actual conditions, the tire unloading mechanism 60 can also be rotatably arranged on the edge column 30, and the tire loading mechanism 50 can be rotatably arranged on the middle column 20, so as to also realize placing the tire into the vulcanizing chamber 40 and taking it out from the vulcanizing chamber 40.

[0046] It should be noted that the V-shaped structure of this embodiment refers to the arrangement of two edge columns 30, which are symmetrically arranged on both sides of the middle column 20, and the middle column 20 and the two edge columns 30 are arranged in a staggered manner in front and back, and are not distributed on the same straight line, thereby forming a V-shaped structure and forming a setting space for two vulcanization chambers 40. The V-shaped structure has the stability of a triangular structure and is symmetrical, which is convenient for the coordination and unity of the actions on both sides of the middle column 20. The middle column 20 and the edge column 30 of the vulcanizer of this embodiment are both provided with an upper mainboard lifting cylinder, and the upper mainboard lifting cylinder of the middle column 20 is arranged on the side thereof close to the edge column 30, and the upper mainboard lifting cylinder of the edge column 30 is arranged on the side thereof close to the middle column 20, so that the arrangement direction of each upper mainboard lifting cylinder is parallel to the arrangement direction of the two edge columns 30, so that when the middle column 20 and the edge column 30 synchronously lift the upper mainboard 41, it is faster and smoother, thereby solving the symmetry problem in the lifting process of the upper mainboard 41. Of course, according to actual conditions, four edge columns 30 may be provided, and the edge columns 30 surround the middle column 20, thereby forming two symmetrical V-shaped structures, and forming four spaces for setting the vulcanization chambers 40 between the edge columns 30 and the middle column 20. The size of the V-shaped structure of this embodiment may also be changed accordingly according to different tire specifications.

[0047] In this embodiment, the tire loading mechanisms 50 connected to different edge columns 30 rotate synchronously or independently; and / or the tire unloading mechanisms 60 connected to the same middle column 20 rotate synchronously or independently. Thus, the vulcanizer can flexibly adapt to the vulcanization requirements of tires of different sizes and types, thereby improving the versatility and adaptability of the equipment. Specifically, in this embodiment, the two edge columns 30 are symmetrically arranged relative to the middle column 20, so the tire loading mechanisms 50 are symmetrically arranged relative to the tire unloading mechanisms 60, and the two tire loading mechanisms 50 can rotate independently relative to the corresponding edge columns 30, so that the two vulcanization chambers 40 work independently without interfering with each other, thereby improving the flexibility of the vulcanizer; the two tire loading mechanisms 50 can also be arranged in linkage, so that the two tire loading mechanisms 50 can act synchronously and complete the loading of the tires in the corresponding vulcanization chambers 40 at the same time, thereby improving the uniformity and uniformity of the actions of different vulcanization chambers 40. The two tire loading mechanisms 50 are symmetrically arranged, so there is also a V-shaped structure between the two tire loading mechanisms 50. This arrangement makes the travel distance of the tire loading mechanism 50 short, and the maximum reasonable travel distance is achieved with the shortest distance. The extension and contraction action will be very accurate, and the actions of the two tire loading mechanisms 50 are symmetrical and coordinated, which is convenient for precision adjustment. Of course, the difference between the two tire unloading mechanisms 60 and the tire loading mechanism 50 is only that the two tire unloading mechanisms 60 are installed on the same middle column 20, and the two tire unloading mechanisms 60 are symmetrically arranged on the middle column 20, and also present a V-shaped structure. The specific action form of the two tire unloading mechanisms 60 is similar to the action form of the tire loading mechanism 50, and can act independently, or the two tire unloading mechanisms 60 can be linked, which will not be repeated. According to actual conditions, when more tire loading mechanisms 50 and tire unloading mechanisms 60 are arranged, the setting mode of linkage or independent movement can also be selected to ensure that the actions between different tire loading mechanisms 50 and different tire unloading mechanisms 60 do not interfere with each other.

[0048] In this embodiment, the tire loading mechanism 50 and the tire unloading mechanism 60 can be lifted and lowered on the corresponding intermediate column 20 and the edge column 30, so that the tire can be loaded or unloaded from the vulcanization chamber 40 more conveniently, reducing the labor intensity of manual operation and improving the safety and efficiency of operation. Specifically, the intermediate column 20 and the edge column 30 of this embodiment can both adopt square columns, and the linear guide guide grooves are processed on the surface of the columns, and together with the seat body 10, a three-column box structure is formed, and the reliability is improved by a one-time processing and forming method. The intermediate column 20, the edge column 30, and the seat body 10 can also be welded by plates or profiles. The tire loading mechanism 50 and the tire unloading mechanism 60 are both provided with lifting linear guide rails, and the linear guide rails can be processed by high-precision machine tools to meet their high-precision requirements. This method can realize the interchangeability between the intermediate column 20 and the edge column 30, and the interchangeability of the positions between the tire loading mechanism 50 and the tire unloading mechanism 60, thereby improving the flexibility of the vulcanizer, which is conducive to saving maintenance costs and adapting to the vulcanization of high-quality tires. In this way, the tire loading mechanism 50 can slide up and down along the linear guide groove of the edge column 30 to realize the loading of tires at different heights, and the tire unloading mechanism 60 can slide up and down along the linear guide groove of the middle column 20 to realize the unloading of tires at different heights, thereby improving the flexibility and adaptability of the tire loading mechanism 50 and the tire unloading mechanism 60, so that the vulcanizer of this embodiment can adapt to various working conditions, and at the same time, the middle column 20 and the edge column 30 can take into account the lifting and lowering of the upper main board 41 of the vulcanization chamber 40 and the lifting and lowering of the tire loading mechanism 50 and the tire unloading mechanism 60, thereby improving the integration of the vulcanizer and simplifying the structure. Of course, there are many ways to set the lifting and lowering of the tire loading mechanism 50 and the tire unloading mechanism 60, and other lifting methods can also be selected, such as a chain-type lifting method.

[0049] In this embodiment, the tire loading mechanism 50 and the tire unloading mechanism 60 both have an operating end 531. When the tire loading mechanism 50 and the tire unloading mechanism 60 rotate into the vulcanization chamber 40, the center of the operating end 531 overlaps with the center of the vulcanization chamber 40, so that the operating end 531 can put the tire into the center of the vulcanization chamber 40 and can take the tire out of the center of the vulcanization chamber 40, which is conducive to uniform heating of the tire during the vulcanization process, thereby improving the vulcanization effect. Specifically, the rotation radius of the tire loading mechanism 50 of this embodiment is the distance from the edge column 30 to the center of the vulcanization chamber 40, and the rotation radius of the tire unloading mechanism 60 is the distance from the middle column 20 to the center of the vulcanization chamber 40, so that the tire loading mechanism 50 can place the tire in the center of the vulcanization chamber 40, so that the tire can be evenly heated. Similarly, the tire unloading mechanism 60 can extend into the center of the vulcanization chamber 40 to take the tire out.

[0050] It should be noted that the vulcanization chamber 40 of the present embodiment has a vulcanization cavity, and the tire is vulcanized in the vulcanization cavity. Therefore, the center of the vulcanization chamber 40 is also the center of the vulcanization cavity. Placing the tire in the center of the vulcanization cavity is conducive to uniform vulcanization of different positions of the tire, thereby improving the quality of the tire. Figure 2 The arrows in the figure indicate the movement directions of the tire loading mechanism 50 and the tire unloading mechanism 60.

[0051] like Figure 4 As shown, in this embodiment, the mold adjustment device 70 includes an adjustment rod 71. When the upper main board 41 and the lower bottom board 42 are buckled, the position of the adjustment rod 71 relative to the lower bottom board 42 is fixed. The adjustment rod 71 is inserted into the upper main board 41 and is threaded with the upper main board 41. When the adjustment rod 71 rotates, it drives the upper main board 41 to move up and down relative to the lower bottom board 42. This way of setting the mold adjustment device 70 on the upper main board 41 of the vulcanization chamber 40 makes the opening and closing of the vulcanization chamber 40 more stable, thereby reducing the wear of the equipment and helping to extend the service life of the equipment. Specifically, the adjustment rod 71 of this embodiment is set as a screw rod, and one end of the screw rod close to the lower bottom board 42 is connected to the lower bottom board 42. The outer peripheral side of the screw rod is provided with an external thread. The upper main board 41 has a threaded hole, so that the screw rod can be inserted into the threaded hole of the upper main board 41, and can drive the movement of the upper main board 41 when there is relative movement between the threaded hole and the screw rod, so as to achieve mold adjustment. Compared with the conventional arrangement of setting the mold adjusting device 70 on the lower base plate 42, the arrangement of the mold adjusting device 70 of the present embodiment is that when the upper main board 41 of the present embodiment moves, the lower base plate 42 is fixed, so that when the booster cylinder for mold closing located at the lower base plate 42 is actuated, it is not necessary to consider the movement distance of the lower base plate 42, which is beneficial to saving the movement stroke of the booster cylinder, thereby helping to reduce the complexity of the vulcanizer structure and saving costs.

[0052] In this embodiment, the upper main board 41 includes a plate body 411 and a nut 412, the nut 412 is rotatably connected to the plate body 411, and moves up and down synchronously with the plate body 411, and the adjustment rod 71 is inserted into the nut 412 and threadedly matched with the nut 412. Specifically, the plate body 411 is set to be rectangular and provided with a mounting hole, the nut 412 is rotatably set in the mounting hole, and the adjustment rod 71 is inserted into the nut 412, so that when the nut 412 rotates relative to the adjustment rod 71, it can drive the plate body 411 to move up and down, but will not drive the plate body 411 to rotate, thereby realizing the movement of the upper main board 41, so that the adjustment of the mold adjustment device 70 is more accurate, thereby improving the quality of tire vulcanization. Optionally, the adjustment rod 71 can adopt a T-screw, and the nut 412 can adopt a T-nut.

[0053] In this embodiment, the mold adjustment device 70 further includes a mold adjustment driving member 72 and a mold adjustment transmission assembly. The mold adjustment driving member 72 is connected to the nut 412 through the mold adjustment transmission assembly. The mold adjustment transmission assembly includes at least one of a gear transmission group, a chain transmission group, and a belt transmission group. Specifically, the mold adjustment driving member 72 of this embodiment is configured as a motor, and the mold adjustment transmission assembly is configured as a chain transmission group. The chain transmission group includes a sprocket chain. In this way, a sprocket is connected to the T-nut, and the motor drives the sprocket chain to drive the T-nut to rotate. The slot on the adjustment rod 71 is fixed by a fixed block to avoid relative rotation between the adjustment rod 71 and the upper main board 41, so that the rotation of the T-nut drives the relative movement between the adjustment rod 71 and the upper main board 41, thereby driving the upper main board 41 to move up and down, thereby realizing the up and down mold adjustment action. One end of the adjusting rod 71 close to the lower bottom plate 42 is fixed to the lower bottom plate 42. When the extended length of the adjusting rod 71 between the upper main plate 41 and the lower bottom plate 42 increases, it is equivalent to raising the upper main plate 41 to increase the mold adjustment height. When the extended length of the adjusting rod 71 between the upper main plate 41 and the lower bottom plate 42 decreases, it is equivalent to sinking the upper main plate 41 to reduce the mold adjustment height. During the mold adjustment process, the lower bottom plate 42 is fixed, and what changes is the extended length of the adjusting rod 71 relative to the upper main plate 41. The length is visible, which is conducive to the safety of the operation. Considering the safety issue, a protective cover can be set on the outside of the adjusting rod 71 and the mold adjustment transmission assembly. Of course, the mold adjustment drive 72 and the mold adjustment transmission assembly can also be set to other structural forms, which can realize the up and down movement of the upper main plate 41. For example, the mold adjustment drive 72 can also be set to other driving modes such as a cylinder, an electric cylinder, etc., and the mold adjustment transmission assembly can also be set to other transmission forms such as a gear transmission group and a belt transmission group.

[0054] In this embodiment, there are multiple mold adjusting devices 70, and the mold adjusting devices 70 are arranged at the corners of the upper main board 41, and the mold adjusting devices 70 act synchronously, so as to realize the uniform and synchronous opening and closing of different positions of the upper main board 41 of the vulcanization chamber 40, so that the opening and closing of the vulcanization chamber 40 is more uniform, thereby improving the quality of tire vulcanization. Specifically, the mold adjustment device 70 of the present embodiment is provided with multiple means that the adjustment rods 71 ​​are provided with multiple, specifically, the plate body 411 of the upper main board 41 is provided with a rectangular plate structure, and mounting holes are provided at the four corners of the plate body 411, and nuts 412 are provided in each mounting hole, and accordingly, four adjustment rods 71 ​​are provided to respectively cooperate with the four nuts 412 with threads, and a set of mold adjustment driving parts 72 and mold adjustment transmission components are provided, so that the same set of mold adjustment driving parts 72 can drive the mold adjustment transmission components to synchronously drive the rotation of the four nuts 412, and then the four corners of the upper main board 41 are evenly stressed, so that the upper main board 41 can be smoothly lifted and lowered, so as to ensure the stability of the mold adjustment of the vulcanization chamber 40.

[0055] Optionally, the adjusting rod 71 and the force pull rod for opening and closing the mold can be set as an integrated structure, so that the height of the adjusting rod 71 is shorter, which is about 400 mm lower than the height of a traditional vulcanizer, thereby making the parts more streamlined, increasing the usable space of the vulcanization chamber 40, and improving safety performance.

[0056] like Figure 5 , Figure 6 As shown, in this embodiment, the mold adjustment device 70 includes an adjustment rod 71 that is inserted into the upper main board 41 and can adjust the upper and lower positions of the upper main board 41. The mold locking device 80 includes: a lock head 81 and a lock sleeve 82. The lock head 81 is arranged at the bottom end of the adjustment rod 71; the lock sleeve 82 is arranged at the upper part of the lower bottom plate 42, and the lock sleeve 82 has a locking hole with the same shape as the lock head 81. When the upper main board 41 and the lower bottom plate 42 are buckled, at least a part of the lock head 81 is located in the locking hole and locked with the lock sleeve 82. In this way, through the detachable connection between the lock head 81 and the lock sleeve 82, the mold locking of the vulcanization chamber 40 is more stable and reliable, and the fixing of the upper main board 41 and the lower bottom plate 42 is convenient and quick, thereby improving work efficiency. Specifically, the end of the adjustment rod 71 of this embodiment close to the lower bottom plate 42 is provided with a lock head 81, and the locking hole is provided at the end of the lock sleeve 82 close to the lock head 81. When the vulcanization chamber 40 needs to be locked, the lock head 81 extends into the locking hole and locks with the lock sleeve 82. The lock head 81 of this embodiment is set as a spline structure, and correspondingly, the locking hole is set as a spline hole, so as to achieve the cooperation between the lock head 81 and the locking hole, and a round hole is set at the bottom of the locking hole, which is connected to the spline structure and arranged along the axial direction of the locking hole, so that when the lock sleeve 82 rotates, the lock head 81 can extend into the round hole and be locked in the locking hole to achieve the locking of the upper main board 41 and the lower bottom board 42. Of course, the shapes of the lock head 81 and the locking hole are not unique, and can also be set to other shapes such as plum blossom shape, gear shape, etc., as long as the locking of the lock head 81 and the lock sleeve 82 can be achieved.

[0057] In this embodiment, there are multiple lock heads 81 and lock sleeves 82, and they are arranged correspondingly. The lock sleeves 82 can be rotatably arranged relative to the lower base plate 42 to change the locking relationship with the lock heads 81. The mold locking device 80 also includes a mold locking driver 83. The mold locking driver 83 is driven and connected to all the lock sleeves 82, and drives all the lock sleeves 82 to rotate synchronously. Specifically, the setting position and setting number of the lock sleeves 82 correspond to the lock heads 81. The lower base plate 42 of this embodiment is similar to the upper main board 41 and is also arranged in a rectangular plate shape. The lock sleeves 82 are arranged on the side of the lower base plate 42 close to the upper main board 41, and one is arranged at each of the four corners of the lower base plate 42 to correspond to the lock heads 81 one by one. When the mold locking driver 83 drives the lock sleeves 82 to rotate, the matching state of the lock sleeves 82 and the lock heads 81 can be changed to achieve the lock heads 81 and the lock sleeves 82. 2, specifically, when the lock sleeve 82 rotates to the point where the shape of the locking hole is axially aligned with the shape of the lock head 81, the lock head 81 and the lock sleeve 82 are in an unlocked state, and the lock head 81 can extend into or withdraw from the locking hole of the lock sleeve 82. When the lock head 81 extends into the locking hole and the lock sleeve 82 rotates to the point where the shape of the locking hole is axially misaligned with the shape of the lock head 81, the lock head 81 is fixed in the locking hole and cannot withdraw from the locking hole, thereby achieving the locking of the upper main board 41 and the lower base plate 42. In this embodiment, a locking drive 83 is provided to simultaneously drive the rotation of four lock sleeves 82 to achieve the synchronous rotation of the four lock sleeves 82, thereby achieving the synchronous unlocking and locking of each lock sleeve 82 and each lock head 81. Of course, the number of lock heads 81 and lock sleeves 82 can be adjusted as needed.

[0058] In this embodiment, the outer peripheral side of the locking sleeve 82 has a radially extending protrusion 821, and the mold locking device 80 also includes a mold locking transmission rod 84, which is connected to the protrusions 821 of two adjacent locking sleeves 82 and drives the two adjacent locking sleeves 82 to rotate synchronously, thereby realizing the synchronous locking and unlocking of each locking sleeve 82 and each locking head 81. Specifically, a protrusion 821 for rotatably connecting with the mold locking transmission rod 84 is provided at one end of the locking sleeve 82 close to the lower bottom plate 42, the protrusion 821 is close to the edge of the lower bottom plate 42, and the protrusion 821 is provided with a rotating shaft connected with the mold locking transmission rod 84, and both ends of the mold locking transmission rod 84 are provided with connecting holes, and the rotating shaft of the protrusion 821 is penetrated in the connecting hole, so as to realize the rotatable connection between the mold locking transmission rod 84 and the locking sleeve 82. In this way, the four locking sleeves 82 are provided with three locking transmission rods 84 and a locking driving member 83, the locking driving member 83 is connected to one of the locking sleeves 82, the locking transmission rod 84 connects the four locking sleeves 82, and the locking driving member 83 drives the rotation of the four locking sleeves 82 at the same time through the locking transmission rod 84, so that the locking sleeves 82 are rotated to the set angle position at the same time, so that the locking hole at the bottom of the locking sleeve 82 is completely locked with the spline structure of the lock head 81, which plays a role in firmly connecting the upper main board 41 and the lower bottom plate 42, that is, locking. When the locking driving member 83 drives one of the locking sleeves 82 to rotate, the other three locking sleeves 82 are passively rotated synchronously with another locking sleeve 82 through the locking transmission rod 84, so that the locking and unlocking of each lock head 81 and each locking sleeve 82 are synchronized, thereby improving the synchronization and stability of the locking of each position of the vulcanization chamber 40. Optionally, the locking driving member 83 can be a cylinder, and the locking driving member 83 can be connected to a joint bearing to drive the locking sleeve 82 to rotate.

[0059] In this embodiment, the mold locking device 80 also includes a mold locking detection component 85 and a mold locking sensor component 86. One of the mold locking detection component 85 and the mold locking sensor component 86 is arranged on the lower base plate 42, and the other of the mold locking detection component 85 and the mold locking sensor component 86 is arranged on the locking sleeve 82. The mold locking detection component 85 detects the position of the mold locking sensor component 86 to determine the state of the mold locking device 80. Specifically, a mold locking detection member 85 is provided on the upper surface of the lower base plate 42 of the present embodiment, and the mold locking detection member 85 is arranged in the structural form of a detection frame, and a proximity switch is arranged on the detection frame. A mold locking sensor 86 is arranged on the side of the raised portion 821 of the locking sleeve 82 close to the lower base plate 42, and the mold locking sensor 86 is arranged in the structural form of a detection column for detecting signals, so that the mold locking detection member 85 and the mold locking sensor 86 are both arranged between the raised portion 821 and the lower base plate 42. When the locking sleeve 82 rotates, the mold locking sensor 86 rotates with the raised portion 821, so that the mold locking sensor 86 approaches or moves away from the mold locking detection member 85, thereby changing the positional relationship between the mold locking detection member 85 and the mold locking sensor 86, so as to realize the detection of the rotation angle of the locking sleeve 82, and then be able to detect whether the mold locking and mold opening are in place. When the mold locking device 80 is in operation, the rotation angle of the protrusion 821 can be accurately controlled by the mold locking driving component 83, and then the rotation angle of the locking sleeve 82 can be controlled, so as to ensure the accuracy of the mold locking position and improve the working performance of the vulcanizer. The mold locking detection component 85 and the mold locking sensor component 86 further ensure the accuracy of the mold locking position.

[0060] like Figure 7 , Figure 8As shown, in this embodiment, the central mechanism 90 includes: a ring cover 91 and a nozzle 92. The ring cover 91 is arranged at the bottom of the vulcanization chamber 40. The ring cover 91 has a steam channel 911. The steam channel 911 has an air inlet 912 and an injection port 913. The nozzle 92 is arranged at the injection port 913. The steam in the steam channel 911 is sprayed into the vulcanization chamber 40 in a fan-shaped distribution through the nozzle 92, thereby ensuring that the tire is evenly heated during the vulcanization process, thereby improving the vulcanization effect. Specifically, the vulcanization chamber 40 of this embodiment also has a capsule for carrying steam inside. The capsule is located above the lower bottom plate 42. The ring cover 91 is located inside the capsule and is connected to the lower bottom plate 42 through a ring seat and other components. The steam channel 911 is distributed along the circumference of the ring cover 91. A plurality of injection ports 913 are provided and distributed on the peripheral side wall of the steam channel 911 and connected to the outer peripheral side of the ring cover 91, so that the steam flowing through the steam channel 911 can be sprayed into the capsule. The ring cover 91 adds a nozzle 92 at the position of the traditional injection port 913. The nozzle 92 adopts an atomizing nozzle 92, so that the steam in the steam channel 911 can be sprayed into the capsule in a fan-shaped distribution, so that the steam is more dispersed and more uniform, and the impact force is very small. In this way, not only can the steam quickly fill the entire capsule cavity, but also this steam spraying method can almost reduce the impact force of the steam on the inner wall of the capsule to zero, effectively protecting the capsule, thereby increasing the service life of the capsule. Experiments have shown that the service life of the capsule can be increased by more than 12%, thereby saving the manufacturing cost of the tire. At the same time, this steam spraying method can also ensure the uniformity of heating the inner wall of the vulcanized tire, thereby improving the quality grade of the tire. Figure 8 The arrow in the figure indicates the direction of steam injection.

[0061] In this embodiment, the inner wall of the air inlet 912 has a plurality of air inlet ribs 9121, and the air inlet ribs 9121 are arranged at intervals along the side wall surface of the air inlet 912, so as to further optimize the distribution of steam and reduce the impact of steam on the capsule. Specifically, the air inlet 912 of this embodiment is located at one end of the steam channel 911 and is connected to the steam channel 911. The steam channel 911 and the air inlet 912 are both located on one side of the ring cover 91 close to the lower base plate 42 to facilitate the connection between the air inlet pipe and the air inlet 912. The steam channel 911 is arranged in the form of a fan-shaped groove, and the air inlet 912 is arranged at one end of the steam channel 911 as a square groove. The air inlet pipe and the air inlet 912 are connected in the vertical direction, so that the steam enters the air inlet 912 and impacts the horizontal side wall of the air inlet 912. The air inlet rib 9121 is arranged on the horizontal side wall of the air inlet 912, so that a concave and convex water surface ripple structure is formed on the side wall of the air inlet 912, so that when the steam impacts the side wall of the air inlet 912, the water surface ripple structure can play a good buffering role for the steam, thereby ensuring the smoothness of the steam flow and reducing the impact of the steam on the capsule. Of course, according to actual requirements, the vertical side wall of the air inlet 912 can also be provided with air inlet ribs 9121 to further guide the distribution of steam. When the air inlet 912 is set to other directions, the setting direction of the air inlet ribs 9121 changes with the direction of the air inlet 912, ensuring that the air inlet ribs 9121 are set on the side wall of the air inlet 912 that is impacted by steam.

[0062] In this embodiment, since the air inlet 912 is configured as a U-shaped structure, the air inlet ribs 9121 are correspondingly configured in a ring shape. Specifically, the air inlet ribs 9121 are also configured as a U-shaped structure, and a zigzag structure is formed between the multiple air inlet ribs 9121. The U-shaped structures of the air inlet ribs 9121 are of different sizes, and the air inlet ribs 9121 are arranged at intervals from the center to the edge of the air inlet 912. In this way, a simulated horizontal corrugated structure is formed on the side wall of the air inlet 912 that is impacted by steam to buffer the steam, thereby ensuring the smooth flow of steam.

[0063] In this embodiment, the ring cover 91 also has an air return port 914. Similar to the setting of the air inlet 912, the inner wall of the air return port 914 has a plurality of air return ribs 9141. The air return ribs 9141 are arranged at intervals along the side wall surface of the air inlet 912, thereby also forming a water surface ripple structure to cushion the impact of steam and ensure the smooth flow of steam. The shape of the air return port 914 of the present embodiment is similar to that of the air inlet 912, but in order to facilitate the backflow of steam, the air return port 914 is not connected to the steam channel 911, but is adjacent to the steam channel 911, and a groove connecting the peripheral side of the ring cover 91 is provided on the side of the ring cover 91 close to the lower bottom plate 42, and the air return rib 9141 is adapted to the shape of the air return port 914 and is set to an N shape, and the N-shaped opening faces the peripheral side of the ring cover 91, and multiple air return ribs 9141 are arranged from small to large from the center of the air return port 914 to the edge of the air return port 914, thereby forming a concave-convex distribution of simulated horizontal corrugated structure, so that when the steam flows out from the capsule to the air return port 914 and then flows out to the air return pipe, the impact on the air return pipe is reduced, thereby improving the stability and reliability of the entire steam delivery system.

[0064] It should be noted that the vulcanizer of this embodiment adopts a B-type central mechanism 90 and a capsule internal temperature measurement technology to make the temperature measurement more accurate, and adopts a multi-channel combined sealing and dustproof, which has a better sealing effect and a longer service life, which can reach about 3 times the industry average.

[0065] like Fig. 9 As shown, in the present embodiment, the tire loading mechanism 50 and / or the tire unloading mechanism 60 includes a clamping device, which includes: a mounting frame 51, a clamping drive member 52, a clamping assembly 53 for clamping the tire and a first adjusting member 54, the clamping drive member 52 is connected to the mounting frame 51, and has an output portion 521, and the movement direction of the output portion 521 is a first direction; the clamping assembly 53 and the mounting frame 51 are movably arranged; the clamping drive member 52 is drivingly connected to the first adjusting member 54, and can drive the first adjusting member 54 to drive the clamping assembly 53 to move along the first direction to clamp the tire; the first adjusting member 54 is rotatably connected to the output portion 521, and is threadedly connected to the clamping assembly 53, and when the first adjusting member 54 rotates, the clamping assembly 53 is driven to move along the first direction through the threaded structure. In this way, by setting the first adjustment member 54 to be rotatably connected to the output part 521 and threadedly connected to the clamping assembly 53, the rotation of the first adjustment member 54 can be converted into movement of the clamping assembly 53 along the first direction, thereby achieving fine adjustment of the diameter of the clamping area formed by the clamping assembly 53 to improve the flexibility and adaptability of the clamping device, while at the same time not affecting the output part 521 driving the clamping assembly 53 to move radially along the tire to clamp or release the tire.

[0066] Specifically, when the first adjusting member 54 rotates, it can drive the clamping assembly 53 to move along the first direction, so as to adjust the diameter of the clamping area formed by the clamping assembly 53. Therefore, the clamping device can not only clamp and release the tire, but also when there is a deviation in the diameter size of the tire mouth, the diameter size of the clamping area can be adjusted to match the tire through the first adjusting member 54, thereby avoiding the situation in which the diameter of the clamping area of ​​the traditional clamping device does not match the diameter of the tire mouth, resulting in the clamping assembly 53 not firmly gripping the tire or even the clamping assembly 53 being unable to extend into the tire mouth to grip the tire, thereby greatly improving the flexibility and adaptability of the clamping device, while avoiding manual interference, which is beneficial to improving tire production efficiency. It should be noted that the first direction, i.e. Fig. 9 The left and right directions in the figure are also one of the radial directions of the tire. When the output part 521 moves along the first direction, it can drive the clamping assembly 53 to approach the tire to clamp the tire or move away from the tire to release the tire. The clamping area refers to the circular area formed by the clamping assembly 53 when the clamping assembly 53 clamps the tire.

[0067] In this embodiment, the clamping assembly 53 includes: an operating end 531 for clamping the tire and a second adjusting member 532, the operating end 531 and the mounting frame 51 are movably arranged, so that the second adjusting member 532 can smoothly drive the operating end 531 to move along the first direction. Considering that the diameter difference of tires of different specifications is larger than the processing error of tires of the same specification, the diameter difference of tires of different specifications is larger, so the second adjusting member 532 is set to quickly adjust the size of the clamping area. The second adjusting member 532 is threadedly connected to the first adjusting member 54, and the second adjusting member 532 and the operating end 531 are adjustable along the first direction, so that the adjustment of the clamping device can not only achieve fine adjustment of the clamping area, but also achieve a larger range of adjustment of the clamping area, so as to be able to clamp tires of different specifications. Specifically, the operating end 531 includes an active slide, a driven slide and a clamping claw, the active slide and the driven slide are arranged along the circumference of the tire, and are both connected to the clamping claw, so that the clamping claw forms a circular clamping area to clamp the tire. The operating end 531 is adjustable through the active slide plate and the second adjusting member 532. When the second adjusting member 532 moves along the first direction, it drives the active slide plate to move along the first direction. The driven slide plate is driven by the active slide plate and moves synchronously with the active slide plate along the radial direction of the tire to adjust the size of the clamping area. Since the second adjusting member 532 is reliably connected to the active slide plate through the latch assembly, it is ensured that the second adjusting member 532 cannot rotate. The second adjusting member 532 is set to a round rod shape with a certain length, or a long plate shape, and the length direction of the second adjusting member 532 is set along the first direction. Since the second adjusting member 532 has a certain length, when adjusting the matching position of the second adjusting member 532 and the operating end 531, it can drive the operating end 531 to a larger displacement, so that the operating end 531 can quickly adjust the size of the clamping area to match tires of different specifications. Optionally, each clamping claw is connected to the mounting frame 51 by a bolt.

[0068] like Fig. 9As shown, in this embodiment, one of the operating end 531 and the second adjusting member 532 has a plurality of adjustment holes arranged along the first direction, and the other of the operating end 531 and the second adjusting member 532 can be switched to dock with different adjustment holes to adjust the position of the operating end 531 and clamp tires of different specifications. Specifically, the adjustment hole of this embodiment is set on the second adjusting member 532, and the operating end 531 is provided with a connecting hole. When the operating end 531 and the second adjusting member 532 are connected, the adjustment hole and the connecting hole are aligned, and the adjustment hole and the connecting hole are fixed by the latch assembly to lock the position of the second adjusting member 532 and the operating end 531. When adjusting the size of the clamping area, remove the latch assembly, align the connecting hole with other adjustment holes to adjust the connection position of the second adjusting member 532 and the operating end 531, thereby adjusting the size of the clamping area. When the clamping device needs to clamp a tire of a larger size, remove the latch assembly, select the adjustment hole closer to the output portion 521 to cooperate with the connecting hole, so that the operating end 531 moves radially outward along the tire, thereby forming a larger clamping area to adapt to the larger tire. When it is necessary to clamp a tire of a smaller size, select the adjustment hole farther away from the output portion 521, and the specific operation process will not be repeated. Of course, according to actual conditions, the operating end 531 may not be provided with a connecting hole, but a protrusion may be provided in the direction toward the adjusting hole, so that the protrusion is provided in the adjusting hole, thereby achieving the fixation of the second adjusting member 532 and the operating end 531, or the adjusting hole may be provided on the operating end 531, and the connecting hole may be provided on the second adjusting member 532, which can also achieve the second adjusting member 532 driving the operating end 531 to achieve the adjustment of the size of the clamping area.

[0069] In this embodiment, the distance between each adjustment hole can be adjusted according to the diameter difference between tires of different specifications to be clamped, and the number of adjustment holes can be set according to the number of different specifications of tires. In this way, when the specification of the clamped tire is changed, the operating end 531 cooperates with the corresponding adjustment hole of the second adjustment member 532, so that the clamping device can quickly adapt to tires of different specifications. Preferably, the second adjustment member 532 is marked with a scale value to correspond to tires of different specifications. When the specification of the gripped tire needs to be adjusted, the operating end 531 is adjusted according to the scale value, and then the second adjustment member 532 and the operating end 531 are fixed by the latch assembly. During operation, the output part 521 moves along the first direction, driving the active slide plate to move, realizing the opening and closing of the entire operating end 531, thereby realizing the gripping and releasing of the tire by the operating end 531.

[0070] like Fig.10 , Fig.11As shown, in this embodiment, the clamping device also includes a locking member 55, the clamping assembly 53 has a threaded segment, the first adjustment member 54 and the locking member 55 are both threadedly matched with the threaded segment, and the thread rotation direction of the first adjustment member 54 is opposite to the thread rotation direction of the locking member 55, thereby locking the position of the first adjustment member 54 along the first direction to prevent the rotation of the first adjustment member 54 from affecting the size of the clamping area and causing failure to clamp the tire when the clamping drive member 52 is actuated. Specifically, the locking member 55 is arranged at one end of the first adjusting member 54 away from the clamping driving member 52, and the second adjusting member 532 has a threaded section at one end away from the operating end 531. Along the first direction, the first adjusting member 54 and the locking member 55 cooperate with the threaded section in sequence. In this way, after the first adjusting member 54 fine-tunes the clamping area, the locking member 55 is installed to lock the first adjusting member 54; when the first adjusting member 54 needs to be rotated to fine-tune the clamping area, the locking member 55 needs to be loosened first to unlock the first adjusting member 54 so that the first adjusting member 54 can rotate, and then the first adjusting member 54 is rotated to make the clamping assembly 53 move along the first direction until it is adjusted to a suitable position for clamping the tire, and then the locking member 55 is tightened to make the clamping driving member 52, the first adjusting member 54, and the clamping assembly 53 become a set of firm and stable structures, and then the clamping device can start the work of clamping the tire. The threaded section of this embodiment is set as an external thread, and the threads of the first adjusting member 54 and the locking member 55 are set as internal threads. Considering that the opposite rotation direction of the two external threads can improve the effectiveness of locking, the rotation direction of the thread of the first adjustment member 54 can be set to be opposite to the rotation direction of the thread of the locking member 55. Optionally, the locking member 55 can be a locking nut 412. Of course, the locking of the first adjustment member 54 can also be achieved in other forms, as long as the locking of the first adjustment member 54 can be achieved.

[0071] In this embodiment, the clamping device further includes a connecting member 56 and a bearing member 57. The connecting member 56 is arranged on the output portion 521. The first adjustment member 54 is rotatably sleeved on the outside of the connecting member 56. The bearing member 57 is arranged between the connecting member 56 and the first adjustment member 54, so that the first adjustment member 54 can be relatively rotatable with the output portion 521. Specifically, the first adjustment member 54, the output portion 521, the connecting member 56, and the bearing member 57 of this embodiment are all arranged in a cylindrical shape, and the first adjustment member 54, the bearing member 57, the connecting member 56, and the output portion 521 are sleeved in sequence according to the outer diameter from large to small. In this way, on the one hand, due to the setting of the bearing member 57, when the first adjustment member 54 rotates, it can drive the clamping assembly 53 to move along the first direction, and at the same time, it has no effect on the output part 521. On the other hand, due to the setting of the connecting member 56, when the output part 521 moves along the first direction, it can drive the clamping assembly 53 to move along the first direction through the transmission of the connecting member 56, the bearing member 57, and the first adjustment member 54, so that the clamping device of this embodiment can achieve fine adjustment of the clamping area to match the tire with errors, and can achieve large adjustment of the clamping area to match tires of different specifications. Of course, according to actual conditions, an annular member such as a copper sleeve can also be used instead of the bearing member 57 to achieve the rotatable setting of the first adjustment member 54 and the connecting member 56.

[0072] In this embodiment, the clamping device also includes a retaining ring 58, which is arranged on the outside of the output part 521, and the end of the connecting member 56 abuts against the retaining ring 58. The connecting member 56 has a stop protrusion 581. A limiting space is formed between the retaining ring 58 and the stop protrusion 581. At least a portion of the first adjusting member 54 is located in the limiting space. The inner wall of the limiting space hinders the movement of the first adjusting member 54 relative to the output part 521 along the first direction, thereby ensuring a reliable connection between the output part 521 and the connecting member 56, and a reliable connection between the connecting member 56 and the first adjusting member 54.

[0073] The connecting member 56 of this embodiment is set to be cylindrical, and a threaded hole is set at one end away from the clamping assembly 53. The threaded hole is set to be a blind hole, and the opening of the threaded hole is facing the direction of the output part 521, so that the output part 521 can extend into the threaded hole and connect with the connecting member 56, and will not pass through the threaded hole. In this way, the two ends of the part where the connecting member 56 is threadedly connected to the output part 521 are respectively limited by a retaining ring 58 and the bottom of the threaded hole, so as to ensure the effective connection between the output part 521 and the connecting member 56 and avoid loosening of the threaded connection. The first adjusting member 54 of this embodiment has a center hole that penetrates the first adjusting member 54 along the first direction, and the connecting member 56 is penetrated in the center hole and is located at the end of the center hole away from the clamping assembly 53. A stop protrusion 581 is set on the outer peripheral side of the end of the connecting member 56 close to the clamping assembly 53. Compared with the first adjustment member 54, the length of the connecting member 56 along the first direction is shorter, so the stop protrusion 581 is located in the center hole and forms a limiting space extending along the first direction with the retaining ring 58, so that a part of the first adjustment member 54 is limited in the limiting space, thereby preventing the connecting member 56 from moving away from the clamping assembly 53 along the first direction and escaping from the center hole, thereby ensuring the reliable connection between the connecting member 56 and the first adjustment member 54. In this way, the cooperation between the retaining ring 58 and the stop protrusion 581 enables the output portion 521 to be reliably connected to the first adjustment member 54 along the first direction.
