Description

Technical Field

[0001] The utility model relates to a component structure of a tire directional vulcanizing machine, in particular to a vulcanizing machine central mechanism nozzle layered variable angle structure. Background Art

[0002] The conventional structure of the medium nozzle on the cylinder head of the central mechanism of the tire shaping and vulcanizing machine is as follows: the injection hole on the cylinder head sprays the medium upward or downward, and the injection angle and injection height are fixed. During nitrogen vulcanization, a large amount of condensed water will be generated on the lower sidewall of the tire. When the high-pressure nitrogen is injected, the nitrogen nozzle will carry away the condensed water and form a vortex to discharge it.

[0003] However, for tires of different specifications, the nozzle angle and height of the cylinder head are different due to the difference in tire height. This requires that when the tire height is changed, the cylinder head with the corresponding height and angle needs to be replaced. In this way, each tire shaping and vulcanizing machine must be equipped with multiple cylinder heads of different heights and angles, which increases manufacturing costs, maintenance and replacement costs. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model proposes a vulcanizing machine central mechanism nozzle layered variable angle structure.

[0005] The invention relates to a vulcanizing machine central mechanism nozzle layered variable angle structure that can solve the existing technical problems. The technical solution includes a cylinder head installed on the lower ring seat of the central mechanism. The difference is:

[0006] 1. The cylinder head comprises at least two layers of cylinder head bodies, an upper layer and a lower layer.

[0007] 2. A medium nozzle I connected to the internal flow channel I is opened on the lower cylinder head body, a medium inlet I connected to the flow channel I is opened at the bottom of the lower cylinder head body, and a through hole penetrating the lower cylinder head body is opened offset from the medium inlet I.

[0008] 3. A medium nozzle II is provided on the upper cylinder cover body and is connected to the internal flow channel II, and the flow channel II is connected to the through hole.

[0009] 4. In the first installation position of the cylinder head, the medium inlet port I is connected to the medium inlet hole opened inside the lower ring seat.

[0010] 5. In the second installation position of the cylinder head, the through hole is connected to the medium inlet hole of the lower ring seat.

[0011] Furthermore, the medium nozzle I of the lower cylinder cover body is opened at an upward inclination.

[0012] Furthermore, the medium nozzle II of the upper cylinder cover body is opened at an angle downward.

[0013] Conventionally, the upper and lower cylinder head bodies are welded together and mounted on the lower ring seat with bolts.

[0014] Beneficial effects of the utility model:

[0015] The utility model adopts a layered variable angle structure of the nozzle of the central mechanism of the vulcanizer, which adopts a combined cylinder head of upper and lower layers. The nozzles of different injection angles and heights can be placed in corresponding positions according to the specification requirements of different tires. The nozzle height and angle of the output can be set as needed, and the requirements of different injection heights and injection angles for each tire are realized. The number of spare parts of the cylinder head is reduced to meet the requirements of multi-specification vulcanization, and the adjustment is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
