Description

Technical Field

[0001] The invention belongs to the technical field of tire vulcanization, and in particular relates to a tire permanent magnet transmission electric heating central mechanism. Background Art

[0002] Tire vulcanization is a process in which a rubber material with a certain plasticity and viscosity is transformed into a soft elastic rubber product or a hard tough rubber product under certain external conditions through the action of chemical or physical factors, thereby obtaining performance. The tire vulcanizer is a motor-driven gear pump and a high-pressure gear pump. It has the structural characteristics of a mechanical vulcanizer, with a compact structure and good rigidity.

[0003] Most of the existing tire vulcanizer electrical heating center mechanisms use electric heating wires to heat nitrogen. After the nitrogen is heated, a circulation pump or a directly connected internal temperature heating and stirring fan is used to stir the nitrogen evenly, resulting in a uniform internal temperature. However, the circulation pump has a large heating power loss, which will cause a waste of resources. At the same time, the sealing ring of the directly connected internal temperature heating and stirring fan for nitrogen mixing has a short life and is not easy to replace, which limits its scope of application.

The uniformity fan 105 is clamped on the inner side of the uniformity warehouse 103, the spiral heating component 106 is arranged on the inner side of the uniformity fan 105 and is sleeved on the outer surface of the upper ring rod 107. The sleeve member 110 is arranged at one end of the main body warehouse 101 close to the rotating mechanism 2, and the upper ring rod 107 passes through the sleeve member 110 and the interior of the rotating mechanism 2 and extends outward; the uniformity warehouse 103 can be sealed by the cover plate 104. Then, the forward and reverse rotation of the uniform fan 105 can realize the interchange of the suction port and the discharge port. A guide port 108 is opened at one end of the uniform chamber 103, and the cross section of the guide port 108 is set in a "U"-shaped structure. The upper and lower ends of the guide port 108 are connected to the air inlet pipe 102 and the exhaust pipe 109 by screws; after the nitrogen enters the capsule, under the rotation of the uniform fan 105, the nitrogen inside the capsule passes through the nitrogen air inlet pipe 102 into the heating rod for heating and then passes through the nitrogen exhaust pipe 109. The heated nitrogen returns to the interior of the capsule, and the nitrogen forms a cycle to achieve a uniform temperature inside the capsule. When the temperature reaches the set value, the capsule is heated and the fan stops; otherwise, the heating continues, and the stirring fan continues to inhale and discharge to form a cyclic heating, thereby achieving a uniform temperature inside the capsule;

[0026] The rotating mechanism 2 includes a driving mechanism 3 and a cylinder fixing plate 401 arranged inside the rotating mechanism 2, and is connected to the cylinder assembly 4 through the cylinder fixing plate 401; the rotating mechanism 2 includes a shell 201, a fixing plate 202, a magnet mounting seat 203, a permanent magnet 204 and an end cover 205, the shell 201 is arranged at one end of the sleeve 110, the fixing plate 202 is arranged on one side of the shell 201 and is fixed to the sleeve 110, the magnet mounting seat 203 is fixed to the inside of the shell 201, the permanent magnet 204 is embedded in the inner side of the magnet mounting seat 203, and one end of the upper ring rod 107 passes through the center of the magnet mounting seat 203 and is connected to the permanent magnet 204, the end cover 205 is fixed to one side of the shell 201 by screws, and the permanent magnet 204 is arranged Arranged according to the Halbach array, the transmission torque is increased, driving the rotation of the magnetic rollers arranged according to the Halbach array with a gap of 8-10mm, and directly connected to the uniform fan 105 in the main chamber 101 through the upper ring rod 107, so the rotation of the stirring fan achieves the purpose of uniform nitrogen mixing.

[0027] By using a 300 servo motor 301, which cooperates with the synchronous pulley 206 through the synchronous belt 302, the end cover 205 is driven to rotate. The sleeve 110 and the synchronous pulley 206 are spaced 6-10 mm apart, driving the magnetic rollers arranged in a Halbach array with a gap of 8-10 mm to rotate. The magnetic field generated by the synchronous pulley magnet attracts the drive shaft magnet of the uniform fan 105.

The set displacement sensor 403 can monitor and control the output end position of the lower ring cylinder 402.
