Description

Technical Field

[0001] The utility model relates to the technical field of tire pressing machines, in particular to a pneumatic tire pressing machine. Background Art

[0002] When tire or wheel hub damage needs to be overhauled or replaced, first tire and wheel hub should be separated, then proceed with subsequent overhaul or replacement work.Traditional method of separating tire and wheel hub has beating method, crowbar method, because the bonding force of tire and wheel hub is larger, these two methods rely on manpower completely, make operator very strenuous, and need repeatedly beating or crowbar operation just can separate tire and wheel hub, time-consuming and laborious, simultaneously each beating or crowbar operation all can bring damage to tire, if often beating or crowbar, can undoubtedly accelerate the damage of tire, affect the service life of tire.Some people design a kind of tire pressing machine for this reason, be specially designed for tire pressing operation. For example, the Chinese utility model patent with the patent number CN220996042U, entitled "A Pneumatic Tire Beading Machine," comprises a main machine, a cylinder with a cylinder body fixedly arranged inside the main machine, a blocking frame arranged on one side of the main machine, and a beading plate arranged between the blocking frame and the main machine. The main machine comprises a base and a chassis rotatably connected to the base. A cylinder is arranged inside the chassis, and a push-out rod of the cylinder extends out of the chassis and toward the blocking frame. The beading plate is connected to the push-out rod of the cylinder. The cylinder drives the beading plate to move linearly, squeezing the tire resting on the blocking frame. Since the beading plate moves linearly, its movement direction and movement trajectory are easier for the operator to grasp, so that the beading plate can more accurately squeeze the tire, preventing damage to the wheel hub due to misalignment. However, there are still several problems in actual use: 1. Due to the strong connectivity between the tire and the wheel hub, the beading plate needs to be repeatedly extended between the tire and the wheel hub to separate the tire and the wheel hub. When the tire is placed against the blocking frame for the first time, the beading plate is driven by the cylinder to move linearly, squeezing the tire against the blocking frame, thus completing the first beading operation; during the second operation, the tire needs to be rotated in place, and the above operation is repeated for another position of the tire. However, due to the heavy weight of the tire, rotation is extremely difficult, and the tire can easily become skewed or even fall over when rotating, which may cause accidental injury and is very dangerous. 2. Since the beading plate can only be extended in the horizontal direction, the position where the tire and the wheel hub are combined needs to be aligned with the beading plate before beading, and when performing beading operations on tires of different models, the tilt angle of the chassis needs to be adjusted to change the height of the beading plate to adapt to different tire models. This requires the user to perform multiple adjustments during use until the beading plate is aligned with the gap between the tire and the wheel hub. It is more complicated to use and has many parts, making it inconvenient to operate. Utility Model Content

[0003] The purpose of the utility model is to provide a pneumatic tire pressing machine, which has a simple structure and saves effort when rotating the tire to perform multiple tire pressing operations. The tire pressing plate can move flexibly during the tire pressing operation, making it easy to face the gap between the tire and the wheel hub. At the same time, the tire pressing machine can be suitable for tires of different models.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A pneumatic tire beating machine includes a connecting rod, a blocking frame is provided on one side of the connecting rod, and a cylinder is provided on the other side of the connecting rod. The pushing rod of the cylinder is connected to the tire beating plate and faces the blocking frame. The connecting rod is fixedly connected to the cylinder mounting seat. The cylinder and the cylinder mounting seat are rotatably connected through a rotating shaft. The rotating shaft is perpendicular to the cylinder. A handle for controlling the direction of the tire beating plate is provided on the tire beating plate.

[0006] Preferably, the cylinder mounting seat includes an upper clamping plate and a lower clamping plate, the cylinder is arranged between the upper clamping plate and the lower clamping plate, and a through hole is provided on the side of the upper clamping plate and the lower clamping plate close to the blocking frame, and a convex shaft is provided on the outer wall of the cylinder, and the convex shaft is passed through the through hole.

[0007] Preferably, the blocking frame includes a vertical frame and a bottom frame connected to the vertical frame, the bottom frame is arranged on a side close to the cylinder, and a rotating assembly is provided on the bottom frame.

[0008] Preferably, the rotating assembly includes a roller shaft, which is parallel to the connecting rod. There are two roller shafts, the highest points of the two roller shafts are higher than the upper surface of the base frame, and the lowest points of the two roller shafts are higher than the ground. There is a gap between the two roller shafts so that the tire can be supported above the two roller shafts.

[0009] Preferably, rotating shafts are provided at both ends of the two roller shafts, and mounting grooves are correspondingly provided on both sides of the base, and the rotating shafts are placed in the mounting grooves and are rotatably connected to the mounting grooves.

[0010] Preferably, the connecting rod is a telescopic rod for adjusting the distance between the blocking frame and the cylinder.

[0011] Preferably, a slope is provided on a side of the base frame away from the connecting rod.

[0012] Preferably, a foot switch is further included, wherein the foot switch is connected to the air pipe of the cylinder. When the foot switch is stepped on, the push rod of the cylinder extends, and when the foot switch is released, the push rod of the cylinder retracts.

[0013] Preferably, the stand comprises a first upright pole and a second upright pole arranged on both sides of the base frame, a connecting rod is provided between the first upright pole and the second upright pole, the connecting rod is inclined, and the first upright pole and the second upright pole are hollow.

[0014] In the above technical solution, the cylinder and cylinder mounting base are rotatably connected via a rotating shaft, which is perpendicular to the cylinder, facilitating the cylinder's left-right swing. The cylinder mounting base is approximately C-shaped and includes an upper and lower clamping plate, each with a through-hole. Protruding shafts corresponding to the through-holes are provided on the upper and lower outer walls of the cylinder. The protruding shafts are inserted into the through-holes to enable horizontal rotation of the cylinder, resulting in a simple structure. The beading plate can also rotate about the push rod. When using the tire beading machine for beading, the foot switch is pressed, and the cylinder pushes the beading plate to extend. Simultaneously, the handle drives the cylinder to rotate horizontally until the push rod is aligned with the gap between the tire and the wheel hub. The center of the beading plate is then aligned with the gap between the tire and the wheel hub. The handle also drives the beading plate to rotate, allowing the curved beading plate to align with the gap between the tire and the wheel hub, facilitating beading of tires of different sizes.

[0015] By providing a base frame, the tire can be placed directly on the base frame to fix its position, which is convenient and quick. Moreover, when the tire is fixed on the base frame, it is parallel to the blocking frame, that is, it will not cause the tire to tilt during the tire pressing operation. Furthermore, by providing a slope at the end of the base frame away from the connecting rod, it is more convenient to push the tire onto the base frame. By providing two rollers on the base frame, both rollers are parallel to the connecting rod, and the two rollers support the tire so that the tire does not contact the ground. When the tire is rotated after the last tire pressing operation, the rollers rotate, guiding the tire and reducing the friction between the tire and the rollers. The user does not need to expend too much effort to rotate the tire to another position where the tire pressing operation is required, which is convenient and quick. Furthermore, by configuring the connecting rod as a telescopic rod, the distance between the tire and the tire pressing plate can be adjusted by adjusting the length of the telescopic rod, thereby making the tire pressing machine adaptable to tires of different thicknesses.

[0016] By tilting the connecting rod, the tire beading plate presses the inner edge of the tire toward the center of the wheel hub, making it easier to detach the inner edge of the tire from the wheel hub and preventing the inner edge of the tire from slipping off the tire beading plate during squeezing.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1 to 2 As shown, the pneumatic tire press comprises a connecting rod 1, a blocking frame 2 being provided on one side of the connecting rod 1, and a cylinder 3 being provided on the other side of the connecting rod 1. The ejection rod 31 of the cylinder 3 is connected to the tire pressing plate 32 and faces the blocking frame 2. The cylinder 3 is connected to the connecting rod 1 via a cylinder mounting base. The cylinder mounting base 4 is approximately C-shaped and includes an upper clamping plate 41 and a lower clamping plate 42. The cylinder 3 is disposed between the upper clamping plate 41 and the lower clamping plate 42. Through holes are provided on the sides of the upper clamping plate 41 and the lower clamping plate 42 near the blocking frame 2. A protruding shaft is provided on the outer wall of the cylinder 3. The protruding shaft is inserted into the through hole to realize horizontal rotation of the cylinder 3. The structure is simple. A blocking cover 43 is also provided on the outside of the two through holes to block the through holes and prevent the protruding shaft from separating from the through hole during use. The tire pressing machine further comprises a foot switch 5, which is connected to the air pipe of the cylinder 3. When the foot switch 5 is stepped on, the push rod 31 of the cylinder 3 is extended. When the foot switch 5 is released, the push rod 31 of the cylinder 3 is retracted.

[0022] The blocking frame 2 includes a vertical frame 21 arranged at one end of the connecting rod 1. The vertical frame 21 includes a first vertical rod 211 and a second vertical rod 212 arranged on both sides of the base frame 22. A connecting rod 213 is provided between the first vertical rod 211 and the second vertical rod 212. The connecting rod 213 is inclined. Because the tire beading plate 32 presses the inner edge of the tire in the direction toward the center of the wheel hub, it is easier to separate the inner edge of the tire from the wheel hub and prevent the inner edge of the tire from slipping off the tire beading plate 32 during squeezing. The first vertical rod 211 and the second vertical rod 212 are hollow. When in use, extension rods can be inserted into the first vertical rod 211 and the second vertical rod 212 to lengthen the first vertical rod 211 and the second vertical rod 212 as needed.

[0023] In this embodiment, the tire beating plate 32 can rotate on its own axis with the push rod 31 of the cylinder 3 as the axis, and a handle 33 is fixedly connected to the end of the tire beating plate 32 connected to the push rod 31. When the tire beating machine is used to perform tire beating operations, the foot switch 5 is stepped on, and the cylinder 3 pushes the tire beating plate 32 to extend. At the same time, the cylinder 3 is driven by the handle 33 to rotate horizontally until the push rod 31 is aligned with the gap between the tire and the wheel hub. The center of the tire beating plate 32 is also aligned with the gap between the tire and the wheel hub. At the same time, the tire beating plate 32 is driven by the handle 33 to rotate, so that the arc-shaped tire beating plate 32 is matched with the gap between the tire and the wheel hub, which is convenient for tire beating operations on tires of different sizes.

[0024] In a preferred embodiment, the blocking frame 2 also includes a base frame 22 connected to the vertical frame 21. The base frame 22 is provided on a side close to the cylinder 3. By providing the base frame 22, the position of the tire can be fixed by directly placing the tire on the base frame 22, which is convenient and quick. Moreover, when the tire is fixed on the base frame 22, it is parallel to the vertical frame 21, that is, when the tire is pressed, it will not cause the tire to tilt. Furthermore, a slope 23 is provided at one end of the base frame 22 away from the connecting rod 1, which makes it easier to push the tire onto the base frame 22. A rotating assembly is provided on the base frame 22, and the rotating assembly includes two rollers 24, and both rollers 24 are parallel to the connecting rod 1. The highest points of the two rollers 24 are higher than the upper surface of the base frame 22, and the lowest points are higher than the ground. There is a gap between the two rollers 24, so that the two rollers 24 support the tire and the tire does not contact the ground. A rotating shaft 241 is fixedly connected to the center position of both ends of the roller shaft 24, and a mounting groove 25 that cooperates with the rotating shaft 241 is provided on both sides of the base. The rotating shaft 241 is placed in the mounting groove 25 and is rotatably connected to the mounting groove. When the last tire pressing operation is completed and the tire is rotated, the roller shaft 24 rotates on itself, guiding the tire and reducing the friction between the tire and the roller shaft 24. The user does not need to spend too much effort to rotate the tire to another position where the tire pressing operation is required, which is convenient and quick.

[0025] In a preferred embodiment, the connecting rod 1 is a telescopic rod for adjusting the distance between the blocking frame 2 and the cylinder 3. The telescopic rod includes a first telescopic rod 11 and a second telescopic rod 12. The second telescopic rod 12 is inserted into the first telescopic rod 11 and is provided with a plurality of sockets 13. The first telescopic rod 11 is also provided with sockets 13. The first telescopic rod 11 and the second telescopic rod 12 are connected by bolts penetrating the sockets 13 on the first telescopic rod 11 and the second telescopic rod 12. The length of the telescopic rod is adjusted by the cooperation of different sockets 13 and bolts, thereby adjusting the distance between the tire and the beading plate 32, so that the tire beading machine can adapt to tires of different thicknesses.

[0026] When using this tire calendering machine for calendering, first remove the wheel and rotate it onto the base frame 22 via the ramp 23, positioning the tire between the two rollers 24. Then, press the foot switch 5, causing the cylinder 3 to extend the calendering plate 32 toward the tire. At this point, turn the handle 33 so that the calendering plate 32 is aligned with the gap between the tire and the wheel hub, allowing the inner edge of the tire to be pressed out of the groove on the wheel hub. Then, rotate the tire and repeat the above steps until the tire is separated from the wheel hub.

[0027] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
