Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vulcanizer equipment, and relates to an inner temperature control circulation injection cylinder head for a tire vulcanizer. Background Technique
[0002] The tire vulcanizer is one of the most critical steps in the tire production process, and temperature control is one of the three key elements of the vulcanizer. At present, most domestic manufacturers have used the nitrogen vulcanization process for tire production, which has the characteristics of economy, energy conservation and environmental protection compared with the traditional process. However, after the inner temperature steam enters, the generated condensed water accumulates at the lower tire side part. The existing cylinder heads of vulcanizers are all adapted to the superheated water process, and the inner temperature injection ports cannot spray to the position of the condensed water, resulting in a measured temperature difference of about 25°C between the upper and lower tire side surfaces. Under such conditions, it is difficult to control the vulcanization degree of the upper and lower tire sides simultaneously, and it is easy to cause under-vulcanization or over-vulcanization. Summary of the Invention
[0003] The utility model aims at the above problems and provides an inner temperature control circulation injection cylinder head for a tire vulcanizer. By leading the injection holes of the original cylinder head to the vicinity of the steel ring and optimizing the inner temperature injection angle, the cylinder head can directly spray to the bottom of the lower tire side, thereby stirring the accumulated condensed water and accelerating the temperature conduction.
[0004] According to the technical solution of the utility model: an inner temperature control circulation injection cylinder head for a tire vulcanizer, including a cylinder head, characterized in that: an annular ring is coaxially arranged on the outer circle of the cylinder head, and the annular ring is arranged above the cylinder head. The cavity inside the annular ring and the cylinder head is connected by a plurality of drainage pipes. A plurality of air knife injection holes are evenly arranged on the annular ring to spray to the bottom of the lower tire side of the tire.
[0005] As a further improvement of the utility model, the annular ring and the cylinder head are also supported and connected by a reinforcing rib.
[0006] As a further improvement of the utility model, the number of the drainage pipes is three.
[0007] As a further improvement of the utility model, the included angle between the axis of the air knife injection hole and the axis direction of the annular ring is an acute angle.
[0008] As a further improvement of the utility model, one end of the drainage pipe is welded and fixed to the air outlet of the cavity inside the cylinder head, and the other end of the drainage pipe is welded and fixed to the air inlet of the annular ring.
[0009] As a further improvement of the utility model, the air inlet end of the air knife injection hole extends to the inner end of the annular ring, and the air outlet end of the air knife injection hole is flush with the surface of the annular ring.
[0010] The technical effect of the utility model lies in that: the structure of this application is reasonable and ingenious. Targeting the shortcomings of existing similar products, targeted improvements are made. On the basis of the original cylinder head, all the original injection holes are led to an annular circle with an outer diameter smaller than that of the lower chuck through welding of drainage pipes. In the annular seamless pipe, air duct injection holes are evenly distributed; and by increasing the lateral angle of the air knife injection holes, the condensed water generated by nitrogen vulcanization can be effectively stirred.

[0014] The specific embodiments of the utility model will be further described below with reference to the drawings.
[0015] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. The described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.
[0016] Figures 1-3 includes a drainage pipe 1, a cylinder head 2, an annular circle 3, an air knife injection hole 4, a reinforcing rib 5, etc.
[0017] As Figures 1-3 shown, the utility model is an inner temperature control circulation injection cylinder head in a tire vulcanizer, including a cylinder head 2. An annular circle 3 is coaxially arranged on the outer circle of the cylinder head 2, and the annular circle 3 is arranged above the cylinder head 2. The cavity inside the annular circle 3 and the cylinder head 2 is connected through a plurality of drainage pipes 1. A plurality of air knife injection holes 4 are evenly arranged on the annular circle 3 to inject on the bottom of the lower tire side of the tire.
[0018] It can be understood that in order to enhance the connection strength between the annular circle 3 and the cylinder head 2, the annular circle 3 and the cylinder head 2 are also supported and connected through a reinforcing rib 5.
[0019] As Figure 2 shown, in specific practice, the number of the drainage pipes 1 in the utility model is set to three, and the corresponding arcs of the three drainage pipes 1 cover the low-lying parts at the bottom of the lower tire side of the tire bead.
[0020] The axis of the air knife spray hole 4 forms an acute angle with the axis direction of the annular ring 3 to ensure that the air can be sprayed directly to the bottom of the lower tire side during operation, thereby stirring the accumulated condensed water and accelerating the conduction of temperature.
[0021] One end of the drainage pipe 1 is welded and fixed to the air outlet of the cavity inside the cylinder head 2 , and the other end of the drainage pipe 1 is welded and fixed to the air inlet of the annular ring 3 .
[0022] The air inlet end of the air knife injection hole 4 extends to the inner end of the annular ring 3 , and the air outlet end of the air knife injection hole 4 is flush with the surface of the annular ring 3 .
[0023] The cylinder cover 2 is provided with bolt holes to achieve installation and fixation during use.
[0024] like Figure 3 As shown, the center of the inlet end of the air knife injection hole 4 coincides with the center of the cross section of the annular ring 3 to achieve a better air outlet effect.
[0025] In order to overcome the situation that nitrogen condensed water accumulates during operation and the cylinder head of the vulcanizer cannot stir it, the present application provides a tire vulcanizer internal temperature control circulation injection cylinder head, which can lead the internal temperature injection hole to the tire steel ring part, and at the same time adopts the air knife injection hole 4 to stir the condensed water accumulated in the low-lying part of the lower sidewall, thereby reducing the temperature difference between the upper and lower parts. The design angle of the air knife injection hole 4 in the present application is based on the lowest depression of the process design size of the sidewall, and in order to stir the condensed water generated by nitrogen vulcanization, the lateral angle of the air knife injection hole 4 is increased.
[0026] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
