Description

Technical Field

[0001] The invention relates to the technical field of tire vulcanization, in particular to a high-efficiency heat energy circulating gas heating process for tire vulcanization. Background Art

[0002] Tire heating and vulcanization is an important step in the tire manufacturing process. It involves converting tire materials into rubber products with specific properties and structures through heating and chemical reactions. The main purpose of tire heating and vulcanization is to make the rubber and additives in the tire material react chemically under specific temperature and pressure, that is, vulcanization reaction. This process will solidify the tire material and achieve ideal properties, including hardness, strength, wear resistance and elasticity.

[0003] There are two existing methods for electrically heating the internal temperature of the capsule body. One is to place the heater and the fan in the central mechanism. The disadvantage of this structure is that the failure rate is high and maintenance is inconvenient. The other is to place the fan (pump) and the heater outside the central mechanism, and connect the fan and the heater in series through the central mechanism inlet and return duct. The pump extracts the gas in the capsule body and heats it through the heater and then returns it to the capsule body, and the cycle continues. Both methods require the electric heating element to exchange heat with the gas. If the air volume is too small, the heating element will become overheated and fail. In addition, the high temperature of the heating element will reduce the life of the capsule body and the central mechanism seal. The electric heating element itself also has safety problems such as leakage.

[0004] In view of this, there is an urgent need for a high-efficiency thermal energy circulating gas heating process for tire vulcanization to improve the deficiencies of the prior art. Summary of the invention

[0005] The object of the present invention is to provide a highly efficient thermal energy circulating gas heating process for tire vulcanization to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a high-efficiency heat energy circulating gas heating process for tire vulcanization, comprising the following steps:

[0007] S1. Connect the circulating conveying centrifugal fan, the pipeline group and the tire group;

[0008] S2, start the circulating conveying centrifugal fan to form an air flow blowing toward the pipeline group;

[0009] S3, the airflow flows at high speed in the pipe group, and the airflow temperature rises;

[0010] S4. High-temperature airflow enters the tire assembly to perform vulcanization operations inside the tire assembly.

[0011] As a further improvement of the present technical solution, in S1, the circulating conveying centrifugal fan includes an impeller and a motor.

[0012] As a further improvement of the technical solution, in S1, the tire set includes a tire body, the interior of the tire body forms a capsule body, and the capsule body is fixed to the ring seat through upper and lower clamping plates to form a closed cavity.

[0013] As a further improvement of the present technical solution, in S1, the pipeline group includes an air inlet pipeline and an air outlet pipeline, and the air inlet pipeline is connected to a circulating conveying centrifugal fan.

[0014] As a further improvement of the technical solution, in S3, the gas is heated by friction with the inner wall of the air inlet pipe, which is used to perform a vulcanization operation on the tire group.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the high-efficiency heat energy circulating gas heating process for tire vulcanization, by installing the pipeline group between the circulating conveying centrifugal fan and the tire group, when the fan is started, the air flow will blow from one end of the air inlet pipeline to the other end. As the gas flows at a high speed in the air inlet pipeline, the air flow rubs against the inner wall of the air inlet pipeline, compresses the gas and generates heat, converting the mechanical energy of the motor into heat energy, thereby realizing the vulcanization operation of the tire group;

[0017] 2. In the high-efficiency thermal energy circulating gas heating process for tire vulcanization, the compression of the impeller and the high-speed friction between the gas and the pipeline are used to heat the gas, that is, the mechanical energy of the motor is directly converted into thermal energy. This heating method eliminates the electric heating element, simplifies the control method, and makes the temperature control more precise. Without a heater, there is no need to consider the heat exchange between the gas and the heater. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Example

[0028] according to Figure 1-Figure 4 As shown, the embodiment of the present invention provides a high-efficiency heat energy circulating gas heating process for tire vulcanization, and the specific steps are as follows:

[0029] Step 1: Connect the circulating conveying centrifugal fan 100, the pipeline group 300 and the tire group 200;

[0030] Step 2: Start the circulating conveying centrifugal fan 100 to form an airflow blowing toward the pipeline group 300;

[0031] Step 3: The airflow flows at a high speed in the pipeline group 300, and the airflow is heated;

[0032] Step 4: The high-temperature airflow enters the tire assembly 200 to perform a vulcanization operation on the tire assembly 200 .

[0033] What needs to be disclosed is that the circulating conveying centrifugal fan 100 includes an impeller 110 and a motor 120. When the circulating conveying centrifugal fan 100 is started, the motor 120 drives the impeller 110 to rotate. Through the movement of the impeller 110, air is sucked into the circulating conveying centrifugal fan 100 and accelerated. Under the action of the impeller 110, the kinetic energy of the air molecules is increased to form a high-speed airflow. The high-speed airflow passes through the impeller 110 and generates dynamic pressure. The dynamic pressure is the pressure energy converted from the kinetic energy of the airflow, which makes the airflow have a certain pressure.

[0034] Furthermore, the tire set 200 includes a tire body 210, and a capsule body 220 is formed inside the tire body 210. The capsule body 220 is fixed to the ring seat through upper and lower clamping plates to form a closed cavity. It can be seen that the capsule body 220 is located inside the tire body 210, and the capsule body 220 is equivalent to the inner tube of the tire body 210. The capsule body 220 is fixed to the ring seat through upper and lower clamping plates to form a closed cavity. During vulcanization, high-temperature and high-pressure gas is filled in, heated and cured, and the air flow pressure squeezes the surface of the tire body 210 toward the mold, and a pattern is formed on the surface of the tire body 210.

[0035] The pipeline group 300 includes an air inlet pipeline 310 and an air outlet pipeline 320, and the air inlet pipeline 310 is connected to the circulating conveying centrifugal fan 100. One end of the air inlet pipeline 310 is connected to the side of the circulating conveying centrifugal fan 100 close to the impeller 110, and the other end of the air inlet pipeline 310 is connected to the capsule body 220. The side of the capsule body 220 away from the air inlet pipeline 310 is connected to the air outlet pipeline 320, and the other end of the air outlet pipeline 320 can be supported on the surface of the circulating conveying centrifugal fan 100, so that the airflow can be stably transported.

[0036] The gas rubs against the inner wall of the air inlet pipe 310 to increase temperature, which is used to vulcanize the tire set 200. When the circulating centrifugal fan 100 is started, the airflow will blow from one end of the air inlet pipe 310 to the other end. As the gas flows at a high speed in the air inlet pipe 310, the airflow rubs against the inner wall of the air inlet pipe 310, compressing the gas to generate heat, converting the mechanical energy of the motor 120 into thermal energy, eliminating the electric heater, making the entire system simpler and more reliable, and heating the gas. The high-speed flow of the gas can make the temperature in the capsule body 220 more uniform, and without a heater, there is no need to consider the heat exchange problem between the gas and the heater.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
