Description

Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, specifically relating to a split-type vulcanizing machine spray structure. Background Technology

[0002] Vulcanization is one of the important processes in tire repair. Tire vulcanization, depending on the internal pressure medium, mainly includes hot water vulcanization, nitrogen vulcanization, and electric heating. Among these, nitrogen vulcanization actually uses steam as the heating medium and nitrogen as the pressure-holding medium. Because nitrogen is used as the pressure-holding medium, it is highly efficient and energy-saving, making it the most widely used process currently.

[0003] Currently, a pressure cap is installed above the cylinder of the vulcanizing machine's central mechanism. Inside the pressure cap is a medium channel for steam or nitrogen to pass through. The pressure cap also has multiple injection holes communicating with the medium channel and a recovery hole for recovering the medium, with the recovery hole at the same height as the injection holes. This structure has two drawbacks: First, because the recovery hole and injection hole are at the same height, some of the injected medium is recovered along with the recovery hole, requiring more medium and consuming more energy when filling the bladder. Second, when the pressure cap is installed on the cylinder, a sealing structure is used to ensure the cylinder's seal. When different injection ports are needed, the entire pressure cap must be replaced, which can easily affect the seal between the pressure cap and the cylinder. Utility Model Content

[0004] This utility model proposes a split-type vulcanizing machine spray structure, which not only facilitates the replacement of the spray nozzle, but also reduces energy consumption, thereby ensuring tire quality.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a split-type vulcanizing machine spray structure, including an end cover for mounting on a cylinder, a spray cover provided on the end cover, a water inlet hole provided on the end cover communicating with the water inlet channel of the cylinder, a water return port provided on the end cover communicating with the water return channel of the cylinder, a medium channel provided on the spray cover communicating with the water inlet hole, and at least one spray port provided on the spray cover communicating with the medium channel and used for spraying the medium.

[0006] As a preferred embodiment of the above scheme, the inner side of the upper end of the end cap is provided with a mounting protrusion, and the inner side of the lower end of the spray cap is provided with a mounting groove that matches the mounting protrusion.

[0007] Further preferably, the end cap includes a medium section that is larger at the top and smaller at the bottom, and an installation section. The water inlet hole is provided on the medium section, and the medium section is provided with a threaded hole for installation with the spray cover. A notch is provided at the lower end of one side of the medium section, and the notch and the cylinder body together form a return water port. The installation section extends into the cylinder body to achieve a sealed installation with the cylinder body.

[0008] Further preferably, the end cap is provided with a first indicator mark to ensure that the end cap can be installed accurately, and the spray cover is provided with a second indicator mark to ensure that the spray cover is installed accurately.

[0009] The beneficial effects of this utility model are:

[0010] 1) The injection hole and return water port are respectively set on the injection cover and the end cover. When changing the injection hole with different angles and sizes, only the injection cover needs to be replaced. There is no need to repeatedly disassemble the end cover. Therefore, it is not only convenient to replace, but also effectively ensures the sealing structure between the end cover and the cylinder.

[0011] 2) The injection hole is located above the return port. When the medium is ejected from the injection hole, it will not immediately flow back along the return port. This allows the medium to be quickly filled into the bladder during filling, effectively reducing heat loss and thus ensuring tire quality and reducing energy consumption.

Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0017] like Figure 1-3 As shown, a split-type vulcanizing machine spray structure mainly consists of an end cover 2 and a spray cover 3. The end cover 2 is installed on the cylinder body 1, and the spray cover 3 is positioned above the end cover 2. To achieve the spraying and recovery of the vulcanizing medium, the end cover 2 is provided with a return water port 2b communicating with the cylinder body's return water channel 1b, and also with a water inlet hole 2a communicating with the cylinder body's water inlet channel 1a. The spray cover 3 is provided with a medium channel 3a communicating with the water inlet hole 2a, and at least one spray port 3b communicating with the medium channel 3a for spraying the medium.

[0018] Because the injection port and return port are respectively located on the injection cap and end cap, and the injection cap is located above the end cap, it is not only convenient to switch the angle, size and height of the injection port by replacing the injection cap, so as to facilitate switching the injection port to adapt to different tires, but also allows the injected medium to quickly fill the bladder, thereby ensuring tire quality and reducing energy consumption.

[0019] The media channel includes a connecting channel communicating with the water inlet orifice and an annular channel circumferentially arranged on the spray cover, with spray holes evenly distributed circumferentially on the spray cover. To facilitate media flow, the axis of the spray holes is not perpendicular to the axis of the spray cover, and the axes of the spray holes are all inclined in the same direction, that is, the spray holes are provided with a circumferential spray angle, so that the sprayed media can circulate in the same direction. Preferably, the spray holes are also provided with a horizontal spray angle to facilitate media recovery, wherein the circumferential spray angle and the horizontal spray angle are set as needed.

[0020] The end cap includes a medium section 2d (larger at the top, smaller at the bottom) and an installation section 2e. The installation section 2e extends into the cylinder body 1 and is sealed to the cylinder body. The medium section is used for the passage of the medium and the installation of the spray cover. Specifically, the medium section 2d has a threaded hole 2f for installation with the spray cover 3, and correspondingly, the spray cover has a bolt through hole 3d for bolts to pass through. A water inlet through hole 2a is provided on the medium section 2d, and a notch 2g is provided at the lower end of one side of the medium section 2d, which, together with the cylinder body 1, forms a return water port 2b. The sealing structure between the installation section and the cylinder body is existing technology.

[0021] To facilitate the installation of the spray cover, a mounting protrusion 2c is provided on the inner side of the upper end of the end cover 2, and a mounting groove 3c matching the mounting protrusion 2c is provided on the inner side of the lower end of the spray cover 3. Simultaneously, to ensure the alignment of the water inlet passage with the water inlet hole, a first indicator mark is provided on the end cover 2 to ensure accurate installation. To ensure the connection between the water inlet hole and the media channel, a second indicator mark is provided on the spray cover 3 to ensure accurate installation.
