[0025] Example

[0026] like Figure 1-2 As shown, this embodiment provides a wear-resistant high-speed sealing cylinder for a bottle blowing machine, comprising a cylinder barrel 1, an end cover 3 and a piston rod 4, wherein the cylinder barrel 1, the end cover 3 and the piston rod 4 are made of lightweight aluminum alloy material, with a relatively light overall mass and high structural strength; the end cover 3 is fixedly mounted on one end of the cylinder barrel 1 by bolts, the piston rod 4 is movably connected to the interior of the cylinder barrel 1, and the two ends of the piston rod 4 are respectively arranged through the end cover 3 and one end of the cylinder barrel 1, a hollow cavity 41 is arranged inside the piston rod 4, at least one air inlet 42 is provided on the surface of the piston rod 4 located inside the cylinder barrel 1, and the air inlet 42 is connected to the hollow cavity 41, and a high-pressure air inlet 101 and a low-pressure air inlet 102 are respectively provided on the side of the cylinder barrel 1, the low-pressure air inlet 102 is connected to the inner cavity of the cylinder barrel 1, and the high-pressure air inlet 101 is connected to the inner cavity of the cylinder barrel 1 and the air inlet 42.

[0027] Among them, a wear-resistant layer 2 is provided on the inner side of the cylinder 1 and the outer side of the piston rod 4. The wear-resistant layer 2 is a porcelain-plated layer. The inner side of the cylinder 1 and the outer side of the piston rod 4 are plated with porcelain through a porcelain-plating process. The surface of the porcelain-plated layer is smooth and wear-resistant, which reduces the friction between the cylinder 1 and the piston rod 4, increases the extension and retraction speed, prevents the cylinder 1 and the piston rod 4 from wear, and increases the service life.

[0028] Furthermore, one end of the piston rod 4 is located in the hollow cavity 41 and is provided with a rod inner cavity sealing ring 43, and one end of the piston rod 4 is sealed by the rod inner cavity sealing ring 43, so that the entering high-pressure gas can only be blown out from the other end, thereby realizing the bottle blowing operation.

[0029] Specifically, a piston 5 is integrally formed on the side of the piston rod 4 at a position inside the cylinder 1, and the piston 5 is fitted with a clearance inside the cylinder 1, and a piston seal ring 51 is sleeved on the outside of the piston 5, and the piston seal ring 51 is set against the inside of the cylinder 1. The inside of the cylinder 1 is divided into two cavities by the integrally formed piston 5, and the two cavities are sealed by the piston seal ring 51, and the two cavities are isolated. One of the cavities is connected to the high-pressure air inlet 101, and the air inlet 42 is also in this cavity. When the high-pressure air inlet 101 inputs high-pressure gas, the piston 5 is pushed to move, and the piston rod 4 is pushed outward. The high-pressure gas also enters the hollow cavity 41 of the piston rod 4 from the air inlet 42 and is blown out from one end of the piston rod 4 to realize the bottle blowing operation. The other cavity is connected to the low-pressure air inlet 102, and the low-pressure gas is blown into the low-pressure air inlet 102, which pushes the piston 5 to move, drives the piston rod 4 to shrink and reset, and waits for the next operation.

[0030] Furthermore, a buffer pad 52 is fixedly connected to one side of the piston 5 close to the low-pressure air inlet 102. After the high-pressure gas passes through the high-pressure air inlet 101, the piston rod 4 will be pushed to move rapidly toward the low-pressure air inlet 102, causing the piston 5 and the cylinder 1 to collide. By providing the buffer pad 52, the impact force is reduced, damage caused by high-speed collision is avoided, and the service life of the product is increased.

[0031] Furthermore, a first guide ring 61 is fixedly connected to the inner side of the end cover 3, and a second guide ring 62 is fixedly connected to the inner side of the end of the cylinder 1 away from the end cover 3, and the first guide ring 61 and the second guide ring 62 are arranged to abut against the piston rod 4. The first guide ring 61 and the second guide ring 62 are made of wear-resistant material, which can not only play a guiding role to fix the movement direction of the piston rod 4, but also avoid direct contact between the piston rod 4 and the end cover 3 to prevent wear caused by long-term movement.

[0032] Furthermore, a first piston rod sealing ring 71 is provided between the end cover 3 and the piston rod 4. By providing the first piston rod sealing ring 71, it is prevented that the internal gas leaks from the end cover 3, thereby affecting the blowing and sealing effects.

[0033] Furthermore, an end cover sealing ring 31 is provided between the end cover 3 and the cylinder barrel 1. The end cover sealing ring 31 is used for sealing to avoid air leakage and affect the blowing and sealing effects.

[0034] Furthermore, a second piston rod sealing ring 72 is provided between the piston rod 4 and the cylinder barrel 1. The second piston rod sealing ring 72 prevents air leakage.

[0035] Furthermore, a dust ring 32 is arranged inside the end cover 3, and the dust ring 32 is arranged against the piston rod 4. The gap between the inner side of the end cover 3 and the piston rod 4 is sealed by the dust ring 32 to prevent external dust from entering.

[0036] The working principle of the utility model is as follows: the high-pressure air inlet 101 is connected to the air pipe for conveying high-pressure air, and high-pressure air is introduced. At this time, the high-pressure air pushes the piston 5 to move, driving the entire piston rod 4 to move, so that the piston rod 4 extends, and the high-pressure air enters the hollow cavity 41 of the piston rod 4 from the air inlet hole 42, and is blown out from the end of the piston rod 4 to realize the bottle blowing operation. After the bottle blowing and sealing are completed, the blowing of high-pressure air is stopped, and the low-pressure air inlet 102 is connected to the air pipe to introduce low-pressure air. The gas pushes the piston 5 to move in the direction, so that the piston rod 4 retreats as a whole and returns to the initial position, waiting for the next operation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
