Description

Technical Field

[0001] This utility model relates to a tire rear inflation device, specifically a large horizontal tire rear inflation device. Background Technology

[0002] The rear-inflation unit is mainly used to inflate tires with nylon and polyester fiber cords as the skeleton during the cooling process after vulcanization to ensure tire quality. Currently, the rear-inflation units used in bias-ply tires and agricultural radial tires on the market are basically vertical rear-inflation units, installed on one side of the vulcanizing machine. One rear-inflation unit can only serve one vulcanizing machine, resulting in low efficiency. Furthermore, for vulcanizing machines that did not previously have a rear-inflation unit, a separate unit must be installed if bias-ply tires and agricultural radial tires need to be produced. However, the existing large-scale vertical rear-inflation units are very inconvenient for tire loading. Utility Model Content

[0024] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0025] The large horizontal rear-inflation device for tires described in this embodiment, such as Figure 1 As shown, it includes a guide rail seat 1, a fixed frame 2, a left chuck mounting seat 3, a left chuck 4, a center rod 5, a right chuck 6, a guide rod 7, a limit nut 8, a screw 9, a moving plate 10, a clamping plate 11, a rotating handle 12, a pin 13, a center screw 14, a drive motor 15, a moving frame 16, a translation cylinder 18, a tire support plate 19, a moving trolley 20, and a lifting cylinder 21.

[0026] like Figure 1 , 2 As shown in Figure 3, a fixing frame 2 is provided on the left side of the guide rail seat 1, and the left chuck 4 is installed on the fixing frame 2 through the left chuck mounting seat 3. The center of the left chuck mounting seat 3 is provided with a cross hole.

[0027] like Figure 1 , 2 As shown, a guide rail groove is provided in the middle section of the guide rail seat 1. The moving trolley 20 can slide left and right in the guide rail groove. A lifting cylinder 21 is installed on the moving trolley 20. The piston rod of the lifting cylinder 21 is connected to the tire support plate 19. A vertical guide rod 22 is installed at the bottom of the tire support plate 19. A guide sleeve that cooperates with the vertical guide rod 22 is provided on the moving trolley 20. The lifting cylinder 21 can drive the tire support plate 19 to move up and down along the direction of the guide rod.

[0028] like Figure 1 , 2As shown, a linear guide rail 17 is installed on the right side of the guide rail base 1, and a movable frame 16 is installed on the slider of the linear guide rail 17. A translation cylinder 18 is installed on the guide rail base 1. The piston rod of the translation cylinder 18 is connected to the movable frame 16. The movable frame 16 can slide left and right along the linear guide rail 17 under the drive of the translation cylinder 18.

[0029] like Figure 1 , 2 As shown in Figure 4, a right chuck 6 and a drive motor 15 are respectively installed at the left and right ends of the movable frame 16. A central rod 5, a central screw 14, a guide rod 7, and a screw 9 are horizontally arranged inside the movable frame 16. The left end of the central rod 5 passes through the mating hole on the movable frame 16 and exits the right chuck 6. The left end of the central rod 5 is provided with a crosshead that matches the cross hole of the left chuck mounting seat 3. The left end of the central screw 14 passes through the central rod 5 through a threaded pair. The right end of the central screw 14 is connected to the output shaft of the drive motor 15. Both ends of the guide rod 7 are fixed to the movable frame 16, and the right end of the screw 9 is fixed to the movable frame 16. There are two guide rods 7 and two screws 9, which are symmetrically distributed above and below the central rod 5. A limit nut 8 composed of double nuts is installed on the screw 9 and can be tightened at any position on the screw 9. A movable plate 10 is vertically sleeved on the right side of the central rod 5. The guide rod 7 and the screw 9 both pass through the movable plate 10. Two semi-circular clamping plates 11 are provided on the right side of the movable plate 10. The two clamping plates 11 are clamped in the annular groove of the central rod 5 and fixedly connected to the movable plate 10 by bolts. A rotating handle 12 that can drive the central rod 5 to rotate is installed on the right end face. The left clamping plate 11 has a locking hole and a locking hole. The pin 13 can pass through the through hole on the rotating handle 12 and be inserted into the locking hole or locking hole of the left clamping plate 11 to limit the rotation position of the central rod 5. The drive motor 15 can drive the central screw 14 to rotate, thereby driving the central rod 5, the clamping plate 11, and the movable plate 10 to move left and right along the guide rod 7. The limiting nut 8 can limit the movable plate 10.

[0030] like Figure 4 As shown, the pin 13 is inserted into the unlocking hole of the left chuck plate 11. At this time, the cross head of the center rod 5 is aligned with the cross hole of the left chuck mounting base 3. When the through hole of the rotating handle 12 is rotated to correspond with the locking hole, the cross head of the center rod 5 is misaligned with the cross hole of the left chuck mounting base 3.

[0031] The large horizontal rear-inflation device for tires described in this embodiment can also be configured with a lifting trolley for transporting tires to the device.

[0032] The working principle of this embodiment is as follows:

[0033] 1. When inflating the tire, first set the position of the limit nut 8 on the screw 9 according to the width of the tire end face;

[0034] 2. Roll the freshly vulcanized tire onto the tire support plate 19. The piston rod of the lifting cylinder 21 extends upward, causing the tire support plate 19 to rise, thereby causing the tire to rise until the center of the tire coincides with the center of the left chuck 4 and the right chuck 6.

[0035] 3. The piston rod of the translation cylinder 18 retracts, causing the moving frame 16 to move to the left, which in turn causes the right chuck 6 to move to the left and approach the tire bead. Under the push of the right chuck 6, the tire slides to the left with the moving trolley 20 until the tire bead is in contact with both the left chuck 4 and the right chuck 6.

[0036] 4. The drive motor 15 rotates forward, driving the central screw 14 to rotate, which in turn drives the central rod 5, the moving plate 10, the clamping plate 11, the rotating handle 12 and the pin 13 (inserted in the locking hole) to move to the left along the guide rod 7 until the moving plate 10 is in contact with the limit nut 8 so that the screw 9 can bear the tension of the tire inflation. At this time, the cross head of the central rod 5 enters and passes through the cross hole of the mounting base 3.

[0037] 5. Pull out the pin 13, turn the rotating handle 12 downwards to make the cross head of the center rod 5 misalign and lock with the cross hole of the mounting base 3, and then insert the pin 13 through the through hole of the rotating handle 12 into the locking hole of the card plate 11.

[0038] 6. The piston rod of the lifting cylinder 21 retracts downward, causing the tire support plate 19 to descend, so that the tire is separated from the tire support plate 19, and then the tire is inflated and cooled.

[0039] 7. After cooling is complete, the piston rod of the lifting cylinder 21 extends upward, driving the tire support plate 19 to rise, so that the tire falls on the tire support plate 19, and then the air pressure inside the tire is released.

[0040] 8. Pull out the pin 13, turn the handle 12 upwards to align the cross head of the center rod 5 with the cross hole of the mounting base 3 to unlock, and then insert the pin 13 through the through hole of the handle 12 into the locking hole of the card plate 11.

[0041] 9. The drive motor 15 reverses, causing the central screw 14 to rotate, which in turn causes the central rod 5 to move to the right along the guide rod 7 to the initial position;

[0042] 10. The piston rod of the translation cylinder 18 extends, driving the moving frame 16 and the right chuck 6 and center rod 5 mounted on it to move to the right to the initial position;

[0043] 11. The piston rod of the lifting cylinder 21 retracts downward, causing the tire support plate 19 and the tire to descend to the initial position, roll out the tire, and prepare for the next cycle.
