DETAILED DESCRIPTION

[0027] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 4 As shown, a tire supporting device for a vulcanizer includes two support seats 1, and the two support seats 1 are symmetrically arranged on the same side of the vulcanizer. A vertical rotating shaft 10 is provided on the upper end faces of the two support seats 1. A tire supporting arm 2 is rotated on the two vertical rotating shafts 10. The tire supporting arm 2 specifically includes a tire supporting section at one end and a driving section at the other end. The matching position of the tire supporting arm 2 with the vertical rotating shaft 10 is located between the tire supporting section and the driving section. The tire supporting section has an arc, and the driving section extends to the middle position of the two support seats 1.

[0029] The driving bracket 3 is also provided with a telescopic driving device 4, which is preferably a device such as an oil cylinder, a pneumatic cylinder, an electric cylinder, etc., and can also be other linear driving devices. The telescopic driving device 4 is connected to a telescopic driving rod 6, and the telescopic driving device 4 can drive the telescopic driving rod 6 to extend and retract. A driving plate 8 is connected to the end of the telescopic driving rod 6, and both ends of the driving plate 8 are connected to the tire supporting arm 2. When the telescopic driving rod 6 is extended and retracted to drive the driving plate 8 to move, it can drive the tire supporting arm 2 to swing around the vertical rotating shaft 10.

[0030] Specifically, long slot holes 9 are provided at both ends of the driving plate 8, and the length direction of the long slot holes 9 is perpendicular to the moving direction of the driving plate 8. The driving section ends of the two tire supporting arms 2 are provided with vertical hinge shafts, and the two tire supporting arms 2 are respectively matched with the long slot holes 9 at both ends of the driving plate 8 through the vertical hinge shafts. When the telescopic driving rod 6 is telescoped to drive the driving plate 8 to move, it can drive the tire supporting arm 2 to swing around the vertical rotating shaft 10 through the cooperation of the long slot holes 9 and the hinge shaft.

[0031] The telescopic driving device 4 of the utility model drives the driving plate 8 to move forward and backward, and the forward and backward movement of the driving plate 8 causes the tire supporting arm 2 to open and close synchronously. Before the start of vulcanization, the tire supporting arm 2 is in an open state and is located outside the steamer wall. After the vulcanization is completed, when the lower ring lifts the tire higher than the upper end surface of the tire supporting arm 2, the tire supporting arm 2 is closed, and after the lower ring falls, the tire remains on the tire supporting arm 2, realizing the tire supporting function.

[0032] Guide rods 7 are provided on both sides of the telescopic driving device 4, and the front end of the guide rod 7 is connected to the driving plate 8. The driving plate 8 is preferably connected with a guide rod fixing block 11, and the guide rod fixing block 11 can fix the front end of the guide rod 7 on the driving plate 8. Two guide sleeves 12 are provided on the driving bracket 3, and the guide rod 7 can be guided and slid in the guide sleeves 12, thereby ensuring the stable opening and closing of the tire supporting arm 2.

[0033] The closure limit adjusting device also includes a closing limit adjusting device and an opening limit adjusting device. The closing limit adjusting device can limit the minimum closing angle of the tire supporting arm 2, and the opening limit adjusting device can limit the maximum opening angle of the tire supporting arm 2. The closing limit adjusting device is preferably configured as a bolt 5 screwed on the driving bracket 3, and one end of the bolt 5 extends to the driving plate 8. When the driving plate 8 moves backward under the drive of the telescopic driving device 4, it can abut against the end of the bolt 5. The bolt 5 is preferably screwed with a first locking nut, and the first locking nut abuts on the driving bracket 3 to lock the length of the bolt 5 extending out of the driving bracket 3.

[0034] The opening limit adjustment device includes a screw rod 13, which is connected to the rear end of the guide rod 7. A limit sleeve 15 is screwed on the screw rod 13. The diameter of the limit sleeve 15 is larger than the diameter of the guide rod 7. When the guide rod 7 moves forward driven by the telescopic drive device 4, the limit sleeve 15 can abut against the drive bracket 3. The limit sleeve 15 of the utility model is preferably set as a light hole 17 near one end of the guide rod 7. The diameter of the light hole 17 is larger than the diameter of the guide rod 7. The limit sleeve 15 can be sleeved on one end of the guide rod 7. This structure can avoid the situation where the screw rod 13 and the guide sleeve 12 cooperate when the guide rod 7 moves forward.

[0035] The utility model utilizes a closing limit adjustment device and an opening limit adjustment device to adjust the opening angle and the closing angle of the tire supporting arm 2, thereby meeting the use of tires of different specifications and vulcanizers of different specifications, has strong versatility, and can be interchanged on different machine models, greatly reducing costs.

[0036] Specifically, a connecting screw hole is provided at the rear end of the guide rod 7 , and the screw rod 13 is screwed into the connecting screw hole. A second locking nut 14 is screwed onto the screw rod 13 , and the second locking nut 14 can abut against the end of the guide rod 7 , thereby locking the screw rod 13 .

[0037] A third locking nut 16 is also threadedly connected to the screw rod 13 . The third locking nut 16 can abut against an end of the limiting sleeve 15 away from the driving bracket 3 , thereby locking the limiting sleeve 15 .

[0038] The above structure is achieved by threading the screw 13 through a connecting screw hole at the rear end of the guide rod 7, and threading the limit sleeve 15 on the screw 13, so that the adjustment range of the limit sleeve 15 on the guide rod 7 is larger, and the length of the screw 13 can be adjusted or replaced with a longer screw 13 to meet a larger adjustment range. In addition, since the limit sleeve 15 frequently contacts the driving bracket 3, the threads of the limit sleeve 15 and the screw 13 will be damaged. Compared with directly replacing the guide rod 7, the cost of replacing only the screw 13 is greatly reduced.

[0039] The specific adjustment process of the utility model is as follows:

[0040] When the closing limit adjustment device is adjusted, the retracted position of the tire supporting arm 2 is controlled by adjusting the distance between the end of the bolt 5 and the driving plate 8. The larger the distance between the end of the bolt 5 and the driving plate 8, the smaller the distance between the two tire supporting arms 2 when the tire supporting device is closed. On the contrary, the distance between the two tire supporting arms 2 becomes larger, so that tires of different specifications can be supported.

[0041] When the opening position adjusting device is adjusted, the position of the limiting sleeve 15 on the screw 13 is adjusted by rotating the limiting sleeve 15, thereby determining the opening size of the tire supporting arm 2, so that the tire supporting device can be placed on vulcanizers of different widths.

[0042] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
