Description

Technical Field

[0001] This utility model belongs to the field of tire vulcanization technology, and in particular relates to a tire permanent magnet drive electric heating center mechanism. Background Technology

[0002] Tire vulcanization is a process in which rubber compounds with certain plasticity and viscosity are transformed into soft elastic rubber products or hard tough rubber products under certain external conditions through the action of chemical or physical factors, thereby obtaining the performance characteristics required for use. Tire vulcanizing machines are driven by motors to rotate gear pumps and high-pressure gear pumps, and have the structural characteristics of mechanical vulcanizing machines, with a compact structure and good rigidity.

[0003] Most existing tire vulcanizing machines use electric heating wires to heat nitrogen. After the nitrogen is heated, it is stirred evenly by a circulating pump or a direct-drive internal temperature heating and stirring fan, resulting in uniform internal temperature. However, the circulating pump heating has a large power consumption, which wastes resources. At the same time, the sealing ring of the direct-drive internal temperature heating and stirring fan has a short life and is not easy to replace, thus limiting its applicability. Utility Model Content

[0010] Furthermore, one end of the uniform chamber is provided with a guide port, and the cross-section of the guide port is arranged in a "U" shape. The upper and lower ends of the guide port are connected to an air intake pipe and an exhaust pipe by screws.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-4 As shown, this utility model is a tire permanent magnet drive electric heating center mechanism, including a nitrogen heating uniform mechanism 1 and a rotating mechanism 2 disposed on one side of the nitrogen heating uniform mechanism 1, and further including:

[0025] The nitrogen heating uniformization mechanism 1 includes a main chamber 101 and an upper ring rod 107 disposed inside it. The main chamber 101 includes a uniformization chamber 103, a cover plate 104, a uniformization fan 105, a spiral heating assembly 106, and a sleeve 110. The uniformization chamber 103 is disposed inside the main chamber 101. The cover plate 104 is bolted to one end of the main chamber 101. The uniformization fan 105 is snapped into the inner side of the uniformization chamber 103. The spiral heating assembly 106 is disposed inside the uniformization fan 105 and sleeved on the outer surface of the upper ring rod 107. The sleeve 110 is disposed at one end of the main chamber 101 near the rotating mechanism 2, and the upper ring rod 107 passes through the sleeve 110 and the interior of the rotating mechanism 2 and extends outward. The cover plate 104 can seal the uniformization chamber 103. Then, the forward and reverse rotation of the uniform fan 105 allows for the interchange of the inlet and outlet. One end of the uniform chamber 103 has a guide port 108, and the cross-section of the guide port 108 is U-shaped. 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 nitrogen enters the capsule, under the rotation of the uniform fan 105, the nitrogen inside the capsule enters the heating rod through the nitrogen inlet pipe 102, is heated, and then passes through the nitrogen exhaust pipe 109. The heated nitrogen then returns to the capsule, forming a circulation to achieve a uniform temperature inside the capsule. When the temperature reaches the set value, the capsule heating and the fan stop; otherwise, heating continues, and the stirring fan continues to draw in and spray out to form a circulating heating, thereby achieving a uniform temperature inside the capsule.

[0026] The rotating mechanism 2 includes a drive mechanism 3 and a cylinder fixing plate 401 disposed therein, and is connected to the cylinder assembly 4 via the cylinder fixing plate 401. The rotating mechanism 2 includes a housing 201, a fixing plate 202, a magnet mounting base 203, a permanent magnet 204, and an end cap 205. The housing 201 is disposed at one end of the sleeve 110, the fixing plate 202 is disposed on one side of the housing 201 and fixed to the sleeve 110, the magnet mounting base 203 is fixed inside the housing 201, the permanent magnet 204 is embedded in the inner side of the magnet mounting base 203, and one end of the upper ring rod 107 passes through the center of the magnet mounting base 203 and is connected to the permanent magnet 204. The end cap 205 is fixed to one side of the housing 201 by screws. The Hellbeck array arrangement increases the transmitted torque, causing the magnetic rollers, spaced 8-10mm apart, to rotate. These rollers are directly connected to the uniform fan 105 inside the main chamber 101 via the upper ring rod 107. Therefore, the rotation of the mixing fan achieves nitrogen mixing. Furthermore, this application eliminates the rotary seal required in traditional direct-connection internal heating mixing fans, significantly improving operation, maintenance, and lifespan. The drive mechanism 3 includes a synchronous pulley 206, a servo motor 301, and a synchronous belt 302. The synchronous pulley 206 is fixed to the outer surface of the end cover 205. The servo motor 301 is fixed to one side of the cylinder fixing plate 401. The synchronous belt 302 is fixed to the output end of the servo motor 301, and the other end of the synchronous belt 302 is connected to the synchronous pulley 206.

[0027] By using a 300 servo motor 301, which works with a synchronous belt 302 and a synchronous pulley 206, the end cover 205 is rotated. The sleeve 110 is 6-10mm away from the synchronous pulley 206, which drives the magnetic rollers arranged in a Heilbeck array with a gap of 8-10mm to rotate. The magnetic field generated by the magnet of the synchronous belt pulley attracts the magnet of the drive shaft of the uniform fan 105. Under the action of magnetic field attraction, the non-contact rotation of the mixing fan is achieved. Therefore, the rotation of the uniform fan 105 achieves the purpose of mixing nitrogen.

[0028] Lower ring cylinders 402 are fixed at the upper and lower ends of one side of the cylinder fixing plate 401, and displacement sensors 403 are provided at one end of the two sets of lower ring cylinders 402. An upper ring cylinder 404 is fixed at the center of the cylinder fixing plate 401, and the upper ring cylinder 404 is connected to the upper ring rod 107. The cylinder fixing plate 401 can limit the servo motor 301 and can also support and limit the lower ring cylinders 402, displacement sensors 403 and upper ring cylinders 404 for subsequent adjustment. The displacement sensor 403 can monitor and control the position of the output end of the lower ring cylinder 402.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
