TECHNICAL FIELD

[0001] The utility model relates to the technical field of tire, specifically relates to a engineering tire tire blank supporting device. BACKGROUND

[0002] In the production process of engineering tire, tire blank forming is a crucial link. However, from the completion of tire blank forming to the subsequent vulcanization process, the tire blank often faces the influence of its own gravity, external environment and other factors. Among them, the self-gravity is a problem that cannot be ignored, which will cause the tire blank to collapse.

[0003] The collapse of the tire blank not only affects the appearance quality of the tire, but more importantly, it will seriously affect its inherent performance. The collapse may cause uneven tire side material and damage to the tire body structure, thereby affecting the performance of the tire.

[0004] At present, for the problem of tire blank collapse, the common supporting device in the industry has many deficiencies, such as complex structure, high cost, poor adaptability to tire blank, and inability to effectively prevent tire blank collapse.

[0005] In summary, it is urgent to develop an engineering tire blank supporting device to provide uniform and strong support for the tire blank, thereby ensuring the quality and performance of the tire blank. UTILITY MODEL CONTENTS

[0007] The technical scheme of the utility model is:

[0008] The engineering tire blank supporting device comprises an inflatable capsule, support plates are fixed at the top and bottom of the inflatable capsule, an inflation valve is arranged on the top support plate, and support protrusions are arranged on the outer wall of the inflatable capsule corresponding to the reverse package tire body end point of the tire blank.

[0009] Preferably, an electric heater is arranged in the inflatable capsule on the bottom support plate.

[0010] Preferably, a temperature and pressure sensor is arranged in the inflatable capsule on the top support plate.

[0011] Preferably, the support protrusions are in the shape of a ring.

[0012] Preferably, anti-skid patterns are arranged on the outer wall of the inflatable capsule.

[0013] Preferably, the inflatable capsule is made of rubber.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. The device of this utility model has a simple structure, is easy to operate and use. It can be supported and removed from inside the tire carcass simply by inflating and deflating, making it convenient and quick. The uniform supporting force of the inflatable bladder of this utility model can effectively protect the tire carcass, reduce tire carcass damage caused by support, and improve the quality of tire vulcanization.

[0018] In the diagram, 1 is the inflatable capsule; 2 is the support plate; 3 is the inflation valve; 4 is the support protrusion; 5 is the electric heater; and 6 is the temperature and pressure sensor. Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0020] Example 1

[0021] like Figure 1 As shown, this embodiment provides an engineering tire carcass support device, including a rubber inflatable bladder 1, the size of which can be designed according to the internal space of the engineering tire carcass. The inflatable bladder 1 has a uniform wall thickness to ensure uniform deformation under pressure, providing stable support. Support plates 2 are fixed to the top and bottom of the inflatable bladder 1, and an inflation valve 3 (which can be a valve stem) is provided on the top support plate 2. Circular support protrusions 4 are provided on the outer wall of the inflatable bladder 1 corresponding to the end point of the tire carcass wrapping around the tire body. Anti-slip patterns are provided on the outer wall of the inflatable bladder 1 to increase friction with the inner surface of the tire carcass and prevent the bladder from sliding inside the tire carcass.

[0022] In use, according to the size of the tire blank, select the appropriate size of the inflatable capsule 1, using a dedicated inflation equipment, such as air pump or air gun, through the inflation valve 3 to the inflatable capsule 1 into the appropriate amount of gas, the capsule to the state of inflation to the inner surface of the tire blank closely. In the process of inflation, pay attention to control the amount of inflation, avoid over inflation of the inflatable capsule 1 rupture or to the tire blank caused by excessive pressure. Inflation pressure should be adjusted according to the size and material of the tire blank, generally can be determined by test the appropriate inflation pressure range. In the process of inflation, the operator should closely observe the inflation of the inflatable capsule 1, to ensure that the uniform inflation and the inner surface of the tire blank fit well.

[0023] Put the inflatable capsule 1 in the tire blank inside the position needs to be supported, the inflatable capsule 1 will rely on its own elasticity and internal gas pressure, to provide uniform support for the tire blank, to prevent the tire blank collapse. In the process of tire blank storage or transportation, the inflatable capsule 1 continues to play a supporting role. When you need to take out the inflatable capsule 1, just open the inflation valve 3, slowly deflated, so that the inflatable capsule 1 shrink, can be easily removed, clean and properly stored for next time use.

[0024] Example 2

[0025] Based on example 1, as shown in Figure 1 The inflatable capsule 1 in the bottom of the support plate 2, provided with electric heater 5; and the inflatable capsule 1 in the top of the support plate 2, provided with temperature and pressure sensor 6.

[0026] Inflatable capsule 1, can be through the temperature and pressure sensor 6 monitoring the pressure inside the inflatable capsule 1, to prevent over inflation of the inflatable capsule 1 rupture or to the tire blank caused by excessive pressure. And in the process of tire blank storage and transportation, can be through the temperature and pressure sensor 6 at any time monitoring the pressure inside the inflatable capsule 1, such as leakage and other abnormal situation should be handled in a timely manner, to ensure the supporting effect of the inflatable capsule 1. In addition, through the electric heater 5 of the inflatable capsule 1, and through the temperature and pressure sensor 6 real-time monitoring of the temperature inside the inflatable capsule 1, can be through the inflatable capsule 1 after heating to maintain the temperature inside the tire blank during storage and transportation, reduce the tire inside the vulcanization defect problem.
