[0025] See also Figures 1 to 6 A tire vulcanizer tire unloading device includes a base 1, a support base 102 is installed above the base 1, a hydraulic cylinder 103 is installed on the support base 102, a mounting base 104 is installed on the output end of the hydraulic cylinder 103, the mounting base 104 is fixedly connected to the mounting ring 203, a tire unloading structure 2 is provided on one side of the support base 102, the tire unloading structure 2 includes a fixing ring 201 and a mounting ring 203, a connecting base 204 is fixedly connected to the mounting ring 203, the connecting base 204 is rotatably connected to the fixing ring 201, a plurality of clamps 3 are provided on the fixing ring 201, the clamps 3 include a sliding rod 301, the sliding rod 301 is connected to the arc groove 202 is slidably connected, a sliding plate 302 is fixedly connected to the sliding rod 301, a plurality of guide grooves 307 are provided on the bottom side wall of the mounting ring 203, the sliding plate 302 is slidably connected inside the guide groove 307, a snap-fit ​​plate 306 is installed on one side of the mounting ring 203, the fixed ring 201 performs tire unloading movement through the clamp 3, a plurality of arc grooves 202 are provided on the fixing ring 201, the clamp 3 is slidably connected to the arc groove 202, the bottom side wall of the mounting ring 203 is slidably connected to the clamp 3, a cylinder 205 is hinged on one side of the support seat 102, and the output end of the cylinder 205 is hinged to the bottom side of the circular periphery of the fixed ring 201.

[0026] During operation, the gripper 3 is located on the inner side of the tire. The tire is vulcanized but the wheel hub is not yet mounted. Then the cylinder 205 is started. When the output end of the cylinder 205 contracts, it can drive the fixing ring 201 to rotate. When the fixing ring 201 rotates, the sliding rod 301 on the gripper 3 slides inside the arc groove 202, and the sliding rod 301 moves along the guide groove 307 on the sliding plate 302 ( Figure 6), from the inner ring position close to the fixing ring 201 to the outer ring position, so that the snap-fit ​​plates 306 on the gripper 3 are in contact with the inner side of the tire, so that the multiple snap-fit ​​plates 306 clamp the tire, and then start the hydraulic cylinder 103 to pick up the tire from the workbench on the vulcanizer, completing the tire unloading process of the vulcanizer; when the tire needs to be placed, the cylinder 205 is extended, so that the cylinder 205 drives the fixing ring 201 to return to its initial position, so that the snap-fit ​​plates 306 are no longer engaged with the inner side of the tire, and the tire will fall off the snap-fit ​​plates 306, completing the overall operation steps of tire unloading.

[0027] Specifically, because both ends of the cylinder 205 are hinged to the support base 102 and the fixing ring 201 respectively, when the cylinder 205 drives the fixing ring 201 to rotate, the cylinder 205 will produce a certain angle deviation and will not cause motion interference with the rotating fixing ring 201.

[0028] like Figure 5 As shown, a wedge-shaped surface 305 is provided on the bottom side of the snapping plate 306, and a connecting rod 303 is fixedly connected to one side of the snapping plate 306. The connecting rod 303 is slidably connected to the inside of the sliding plate 302, and the sliding plate 302 is threadedly connected with a bolt 304. When encountering a tire with a smaller diameter, and the overall length of the traditional clamper 3 is not enough to make the snapping plate 306 located on the inside of the tire, the bolt 304 can be rotated to make a part of the length of the connecting rod 303 come out from the sliding plate 302, and the length between the snapping plate 306 and the sliding plate 302 is adjusted so that the snapping plate 306 can be located on the inside of the tire, thereby being able to clamp the small tire, and then the bolt 304 can be rotated again to fix the position of the connecting rod 303 inside the sliding plate 302.

[0029] Furthermore, the wedge-shaped surface 305 facilitates the tire to fall off the fastening plate 306 during tire removal, thereby preventing the inner wall of the tire from being scratched against the fastening plate 306 .

[0030] like Figure 3As shown, a limiting half ring 4 is installed on the lower side of the fixing ring 201, and an adjustment groove is opened on the bottom side of the fixing ring 201. A threaded rod 401 is rotatably connected inside the adjusting groove, and the threaded rod 401 is threadedly connected to the limiting half ring 4. The function of the multiple limiting half rings 4 is that when the hydraulic cylinder 103 drives the tire unloading structure 2 to descend, the limiting half ring 4 limits the outer ring of the tire. The limiting half ring 4 will be located on the outer ring of the tire to prevent the buckling plate 306 from contacting the inner side wall of the tire, causing the tire to deviate. When the length of the buckling plate 306 changes, the threaded rod 401 can be rotated to move the limiting half ring 4 on the bottom side of the fixing ring 201, so that the limiting half ring 4 can always fit the outer ring of the tire, and a scale number is set at the junction of the limiting half ring 4 and the fixing ring 201. The moving distance of the limiting half ring 4 is recorded by the scale number, so as to facilitate the keeping consistent movement position of the multiple limiting half rings 4.

[0031] like Figure 1 As shown, a rotating table 101 is rotatably connected to the base 1, and a support seat 102 is fixedly connected to the rotating table 101. An extension seat 5 is rotatably connected to one side of the base 1, and a plurality of buffer seats 501 are fixedly connected to the extension seat 5. A buffer rod 502 is installed on the buffer seat 501, and a transport rack 503 is installed on the buffer rod 502. A reduction motor is installed inside the base 1, and the reduction motor can drive the rotating table 101 to rotate, thereby changing the position of the entire support seat 102 and the tire unloading structure 2. The tire clamped on the tire unloading structure 2 can be adjusted to the upper side of the transport rack 503, and then the tire is placed on the transport rack 503. Under the action of gravity and friction, the tire on the transport rack 503 will flow to the conveyor belt through the rollers, which is convenient for subsequent processing of the tire.

[0032] Working principle: When working, the hydraulic cylinder 103 is used to make the gripper 3 located on the inner side of the tire. The tire during vulcanization has not yet been installed on the wheel hub. Then the cylinder 205 is started. When the output end of the cylinder 205 contracts, it can drive the fixed ring 201 to rotate an angle. When the fixed ring 201 rotates an angle, the sliding rod 301 on the gripper 3 slides inside the arc groove 202, so that the sliding rod 301 moves from the position close to the inner ring of the fixed ring 201 to the outer ring position, so that the buckle plate 306 on the gripper 3 fits the inner side of the tire, so that multiple buckle plates 306 clamp the tire, and then the hydraulic cylinder 103 is started again to pick up the tire from the workbench on the vulcanizer, completing the tire unloading process of the vulcanizer; when it is necessary to place When the tire is unloaded, the cylinder 205 is extended, and the cylinder 205 drives the fixing ring 201 to return to its original position, so that the snap plate 306 is no longer engaged with the inner side of the tire, and the tire will fall off the snap plate 306, completing the overall operation steps of tire unloading. When the traditional clamper 3 is not long enough to make the snap plate 306 located inside the tire, the bolt 304 can be rotated to make a part of the length of the connecting rod 303 come out from the sliding plate 302, and the length between the snap plate 306 and the sliding plate 302 can be adjusted so that the snap plate 306 can be located inside the tire, thereby clamping the small tire, and then the bolt 304 can be rotated again to fix the position of the connecting rod 303 inside the sliding plate 302.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
