Description

Technical Field

[0001] The present invention relates to the technical field of automobile tire production, and specifically relates to a pressurizing device and a pressurizing method for a silent sponge tire. Background Technique

[0002] Tire noise is generated when the tire rubs against the road surface when the vehicle is driving at high speed. The tire noise size depends on the road conditions and vehicle conditions. The worse the road conditions, the greater the tire noise. In addition, there are significant differences in tire noise generated by asphalt roads and concrete roads. To this end, sound-absorbing sponges are mostly installed inside automobile tires for sound insulation.

[0003] Currently, when pasting the sponge on the inner side of the tire, it is necessary to press the sponge on the inner side of the tire so that the sponge can closely adhere to the inner wall of the tire. However, the existing tire sponge pressurizing device can only be used for pressurizing tires of specific sizes. When pressurizing tires of different specifications, different pressurizing devices need to be used, which makes it inconvenient to pressurize the tires. In addition, when pressurizing the sponge on the inner side of the tire, the tire cannot rotate simultaneously with the pressing head, so that the force on each part of the sponge on the inner side of the tire is prone to be uneven, resulting in a poor sponge pressurizing effect.

When in use, through the rotation of the working output end of the third motor 901, the first connecting belt 903 on one side is driven to rotate, so that the second rotating column 909 above rotates, which can drive the first pressing wheel 906 to move forward and drive the expander 905 to move forward to expand the bead of the tire 3. Then, the first pressing wheel 906 is inserted into the inner side of the tire 3, and the sixth motor is operated. The pressing plate 912 on one side is driven to move through the second connecting belt 910, which can drive the sliding block 914 above to move.

[0041] Further, fixing blocks are fixedly installed on both sides of the base 2. Chutes are provided on the two fixing blocks.

[0044] Example 2

[0045] Based on Example 1, as Figures 1-9 , on the middle parts of the two legs 1 under the base 2, mounting blocks 22 are fixedly installed.

After adjusting the height of the tire 3, the first cylinder 11 works to drive the connecting rod 14 to rotate. The rotation of the connecting rod 14 can drive the two support plates 23 on both sides to rotate. The rotation of the support plates 23 can drive the guide plates 24 to rotate. Since the guide plates 24 and the bottoms of the support rods 19 are connected to each other, the upper support rods 19 can be driven to rotate, and then the placing frames 17 can be driven to move. Through the mutual meshing between the first gear 20 and the second gear, the four placing frames 17 can be driven to hold and center the tire 3. And the fourth motor 13 works to drive the lower first roller 12 to rotate and push the tire 3 to rotate.

[0046] Example 3

[0047] Based on Example 1, as Figures 1-9 , a fifth motor 30 is fixedly installed on the fixing plate 6. A first runner 25 is fixedly installed at the output end of the fifth motor 30. Two third runners 28 are arranged on one side of the bottom of the fixing plate 6. A second runner 26 is rotatably connected to one side of the third runner 28 below the fixing plate 6. The first runner 25, the second runner 26, and the third runners 28 are rotationally connected through a transmission belt 27. Expansion rods 29 are arranged on both of the two third runners 28. The top ends of the expansion rods 29 penetrate through the base 2 and extend onto the base 2. Then the fifth motor 30 works, and the height of the expansion rods 29 can be adjusted through the transmission belt 27, so that the expansion rods 29 can move up and down, and thus the height of the tire 3 can be adjusted.

[0048] Example 4

[0049] Based on Example 1, as Figure 10 , a method for pressurizing a silent sponge tire includes the following steps:

[0050] Step 1: In the initial state, place the tire 3, and detect the placement position of the tire through the tire detector 8;

[0051] Step 2: Detect the tire. The tire detector 8 detects the tire and sends the height model to the fifth motor 30. The fifth motor 30 operates, drives the telescopic rod 29 to work through the conveyor belt, and is used to lift the tire 3 to the required height;

[0052] Step 3: After the placement is completed, clamp and hold the tire. The first cylinder 11 operates, drives the connecting rod 14 to rotate, and then drives the four placement frames 17 to hold and center the tire 3. Moreover, the fourth motor 13 operates, drives the lower roller 12 to rotate, and pushes the tire 3 to rotate;

[0053] Step 4: Send the pressure maintaining mechanism to the required position, open the pressure maintaining mechanism according to the formula, expand the bead of the tire 3, and then the pressure maintaining mechanism pushes the crawler 706 or the first pressing wheel 906 to press against the inner wall of the tire 3, start pressing the sponge, and rotate at the same time, for a total of 1 - 2 turns;

[0054] Step 5: After completion, restore the action. The pressure maintaining mechanism retracts, the crawler 706 or the first pressing wheel 906 retracts, the expander retracts at the same time, the whole retracts to the minimum locked position, the hoop mechanism stops rotating, opens, and takes away the tire 3.

[0055] Working principle: When pressurizing the sponge inside the tire 3, first place the tire 3 on the base 2. After completion, the tire detector 8 detects the position of the tire 3, so as to determine its position. At the same time, the height of the tire can be detected through the tire detector 8. Then the fifth motor 30 operates, and the height of the telescopic rod 29 can be adjusted through the conveyor belt 27, so that the telescopic rod 29 can move up and down, thereby adjusting the height of the tire 3.

[0056] After adjusting the height of the tire 3, the first cylinder 11 operates, drives the connecting rod 14 to rotate. The rotation of the connecting rod 14 can drive the two - side support plates 23 to rotate. The rotation of the support plates 23 can drive the guide plate 24 to rotate. Since the guide plate 24 is connected to the bottom of the support rod 19, it can drive the upper support rod 19 to rotate, and then drive the placement frame 17 to move. Through the meshing between the first gear 20 and the second gear, the four placement frames 17 are driven to hold and center the tire 3. Moreover, the fourth motor 13 operates, drives the lower roller 12 to rotate, and pushes the tire 3 to rotate.

[0057] When performing the pressurization operation on the inner side of the tire 3, the first motor 712 operates, and the output end rotates, which can drive one - side rotation

[0058] The column 710 rotates, so as to drive the outer connecting block 711 to move reciprocally, thereby driving the upper connecting frame 701 to move, enabling the spreader 703 to spread the tire 3 finger opening, so that the crawler 706 penetrates into the inner side of the tire 3 and closely adheres to the inner wall of the tire 3. Then, the motor 713 operates, and the output end rotates to drive the upper conveying wheel 704 to rotate. The rotation of the conveying wheel 704 drives the two conveying wheels 709 to rotate through the crawler 706, thereby helping the crawler 706 to press the sponge inside the tire 3.

[0059] When the pressing member 7 needs to be replaced, the pressing member 7 is removed and the rolling member 9 is replaced. During use, the output end of the motor 901 rotates to drive the connecting belt 903 on one side to rotate, thereby rotating the upper rotating column 909, so as to drive the pressing wheel 906 to move forward and drive the spreader 905 to move forward to spread the tire 3 finger opening. Then, the pressing wheel 906 penetrates into the inner side of the tire 3, and the motor 6 operates to drive the pressing plate 912 to move through the connecting belt 910, thereby driving the upper sliding block 914 to move. When the sliding block 914 moves, it can drive the pressing wheel 906 and the pressing wheel 907 on one side to change their positions, so that the pressing wheel 906 and the pressing wheel 907 jointly press the sponge inside the tire 3.
