Description

Technical Field

[0001] The utility model relates to the technical field of tires, and particularly relates to a tire inflation positioning device. Background Art

[0002] After the tire vulcanization is completed, it needs to be parked and cooled to prevent deformation and unstable dimensions during the cooling process, which may cause difficulties in inflation. The post-inflation device is mainly used to inflate and cool the vulcanized tire in time to ensure the correct size of the tire, reduce the permanent deformation of the tire carcass, and improve the performance of the tire. In the post-inflation process of the tire, the vulcanized tire needs to be placed on the clamping device so that the clamping device fits the steel rim surface of the tire, and then it is positioned and fitted on the other steel rim surface of the tire, and the tire is inflated through the inflation device. However, in actual production, during the tire unloading process after inflation, when the clamping device withdraws and releases the tire, there may be an adhesion phenomenon of the tire, which affects the smooth progress of the process and the subsequent transportation of the tire.

[0029] Example 1, see Figures 1-3 :

[0030] A tire inflation positioning device includes two rim members 1 arranged opposite to each other. The rim members 1 are located above two tire feeding rods 2. The two tire feeding rods 2 are arranged side by side on a horizontal plane. The arrangement direction of the two tire feeding rods 2 is perpendicular to the arrangement direction of the two rim members 1. The two tire feeding rods 2 are used to place the tire 9, and the two rim members 1 are used to center and clamp the tire 9. It can be understood that, taking Figure 1 as an example, the arrangement direction of the two tire feeding rods 2 is from front to back, and the arrangement direction of the two rim members 1 is from left to right.

[0031] Both ends of the tire feeding rod 2 are movably connected to the shaft fixing seat 4 through a support shaft 3. A return spring 5 is arranged between the tire feeding rod 2 and the shaft fixing seat 4. When the tire feeding rod 2 is stressed and its position moves, the tire feeding rod 2 is reset under the action of the return springs 5 at both ends.

[0032] As an implementation manner, the tire feeding rod 2 and the support shaft 3 are coaxially arranged, and the return spring 5 is sleeved on the support shaft 3.

[0033] As an implementation manner, the tire feeding rod 2 is a hollow rod, and the support shaft 3 penetrates through the hollow rod.

[0034] As an implementation manner, both ends of the tire feeding rod 2 are recessed to form first recesses 20 for placing the return spring 5. One end of the shaft fixing seat 4 facing the tire feeding rod 2 is recessed to form second recesses 40 for placing the return spring 5. Both ends of the return spring 5 are respectively arranged in the first recesses 20 and the second recesses 40.

[0035] Both rim members 1 are installed on a lifting device. Any lifting device is connected to the corresponding rim member 1 through a lateral moving device. Any rim member 1 is provided with an inflation port 6 for inflating the tire 9. During use, first place the tire 9 on the tire feeding rod 2. The lateral moving device drives the rim member 1 on this side to push the tire 9 towards the other rim member 1. The tire feeding rod 2 also moves along with the tire 9. The tire 9 is clamped between the two rim members 1. Then the lifting device drives the rim member 1 to lift the tire 9, and then inflate the tire 9 through the inflation port 6 to complete the process of clamping and inflating the tire. At the same time, after the tire 9 is lifted, the tire feeding rod 2 is reset under the action of the return spring 5.

[0036] Any rim member 1 is installed with a tire unloading cylinder 7. The ejecting end of the tire unloading cylinder 7 is arranged towards the direction of the other rim member 1. When the process of clamping and inflating the tire is completed, the lifting device drives the rim member 1 to descend, and the lateral moving device drives the rim member 1 on this side to move away from the tire 9. The ejecting end of the tire unloading cylinder 7 ejects forward to push the tire 9 off the rim member 1 on this side, and the tire 9 falls onto the tire feeding rod 2.

[0037] As an implementation manner, the number of the tire unloading cylinders 7 is 2 - 3. Preferably, when the number of the tire unloading cylinders 7 is 2, the two tire unloading cylinders 7 push out the tire 9 from the upper and lower sides or the left and right sides of the tire 9 respectively, and the tire unloading effect is better.

[0038] As an implementation manner, the rim member 1 includes a front end portion 13. A stepped side portion 14 is arranged on the outer side of the front end portion 13 and faces backward, which is convenient for adapting to tires of different sizes and models and for clamping and fixing the tire 9. The tire unloading cylinder 7 is arranged on the back side of the front end portion 13. It can be understood that a tire unloading opening is arranged on the side of the rim member 1 facing the tire 9, which is convenient for the ejecting end of the tire unloading cylinder 7 to eject forward, and the front end portion 13 is circular.

[0039] As an implementation manner, the lifting device adopts a vertical ball screw drive device.

[0040] As an implementation manner, the shaft fixing seat 4 is installed on the transmission device. Preferably, the transmission device adopts a belt drive device, and the shaft fixing seat 4 is installed on the synchronous belt 8 of the belt drive device. After the tire 9 is clamped and the tire is unloaded, the synchronous belt 8 drives the tire 9 to move out.

[0041] As an implementation manner, the two rim members 1 are respectively a left rim 11 and a right rim 12. The right rim 12 is installed on the lifting device on the right side. The inflation port 6 is arranged on the left rim 11, and the tire unloading cylinder 7 is arranged on the right rim 12. The left rim 11 is installed on the lifting device on the left side through a lateral moving device, and the lateral moving device is used to drive the left rim 11 to approach or move away from the right rim 12. In some implementation manners, the lateral moving device can adopt an electric push rod or a cylinder.

[0042] The working principle of this embodiment:

[0043] First, place the tire 9 on the tire feeding rod 2. The belt drive device drives the synchronous belt 8 to convey the tire 9 to the working position below the rim member 1. The vertical ball screw drive device drives the two rim members 1 to descend. Among them, the left rim 11 pushes the tire 9 towards the right rim 12 under the action of the lateral moving device, and the tire feeding rod 2 also moves towards the right along with the tire 9. The tire 9 is clamped between the left rim 11 and the right rim 12. The lifting device drives the rim member 1 to lift the tire 9. After the tire 9 is lifted, the return spring 5 on the right side is loosened to make the tire feeding rod 2 reset. The tire 9 is inflated through the inflation port 6 to complete the process of clamping and inflating the tire. Subsequently, the lifting device drives the rim member 1 to lower the tire 9. The left rim 11 moves away from the right rim 12 under the action of the lateral moving device. The ejecting end of the tire unloading cylinder 7 ejects forward and pushes the tire 9 off the right rim 12. The tire 9 falls on the two tire feeding rods 2, and the belt drive device moves this tire 9 out.
