Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine equipment technology, and in particular to a vulcanizing machine steam chamber that can precisely control the mold height. Background Technology

[0002] Vulcanizing machines are indispensable equipment in rubber product manufacturing, widely used in the vulcanization and molding processes of tires, hoses, rubber shoes, and other rubber products. The steam chamber of the vulcanizing machine, as one of its core components, directly affects the quality and production efficiency of the rubber products due to the precision of its mold height control. Traditional methods for controlling the mold height of the steam chamber in vulcanizing machines mainly rely on manual operation or simple mechanical limit devices, which have several shortcomings. Firstly, manual operation cannot guarantee the accuracy of each mold height adjustment, and is prone to product quality instability due to differences in operator experience and operational errors. Secondly, mechanical limit devices have limited precision and are prone to wear and tear over long-term use, reducing their reliability and affecting the accuracy of mold height adjustment. Furthermore, traditional methods cannot achieve automated control, resulting in low production efficiency and failing to meet the high-efficiency and precision requirements of modern rubber product manufacturing.

[0003] Therefore, developing a vulcanizing steam chamber capable of precisely controlling the mold height is of great significance for improving the quality and production efficiency of rubber products. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a vulcanizing machine steam chamber that can precisely control the mold height.

[0005] The purpose of this utility model is achieved as follows:

The upper steam chamber is located below a crossbeam, the lower steam chamber is located below the upper steam chamber, and the mold adjustment device is located on the upper steam chamber. The bottom of the crossbeam is connected to a flange stud, the bottom of which is inserted into and connected to a mold adjustment nut. A mold adjustment gear is fitted on the top of the mold adjustment nut, and the lower part of the mold adjustment nut is connected to an upper support plate.

[0007] The mold adjustment device includes a motor, a connecting rod, a gearbox, an encoder, a gear shaft, a mold adjustment pinion gear, and a mold adjustment large gear. The motor is connected to the top of the connecting rod via a connecting rod coupling. The bottom of the connecting rod is inserted into a connecting sleeve. The connecting rod is detachably connected to the gearbox via the connecting sleeve.

[0008] The gearbox is equipped with a small reduction gear and a large reduction gear. The output shaft of the small reduction gear is detachably connected to the connecting rod via a connecting sleeve. The large reduction gear meshes with the small reduction gear and is sleeved on the gear shaft.

[0009] The gearbox is equipped with an encoder, which is connected to the top end of the gear shaft via an encoder coupling, and the lower end of the gear shaft extends out of the gearbox.

[0010] The gearbox is provided with a mold adjustment pinion below it, which is sleeved on the gear shaft; the mold adjustment pinion meshes with the mold adjustment gear, and the mold adjustment gear is connected to the mold adjustment nut.

[0011] Furthermore, the motor is mounted on a motor bracket, which is fixed to the outer wall of the crossbeam.

[0012] Furthermore, the gearbox is provided with an encoder support, and an encoder is mounted on the encoder support.

[0013] Furthermore, the gearbox is provided with a connecting flange, a packing flange, and a mold-adjusting pinion at its lower part. The connecting flange, the packing flange, and the mold-adjusting pinion are sequentially sleeved on the gear shaft. A copper pressure cap is provided between the connecting flange and the packing flange, with the upper part of the copper pressure cap located inside the connecting flange and the lower part located inside the packing flange.

[0014] Furthermore, a V-shaped fabric clamping ring is provided below the copper pressure cap, and a second copper sleeve is provided below the V-shaped fabric clamping ring. Both the V-shaped fabric clamping ring and the second copper sleeve are located inside the packing flange.

[0015] Furthermore, the upper support plate is also provided with an anti-rotation plate. One end of the anti-rotation plate is fixed to the bottom of the upper support plate, and the other end is stuck on the guide plate on the inner wall of the upper steamer to prevent the upper support plate from rotating with the adjusting screw nut.

[0016] Furthermore, the large adjusting gear and the adjusting screw nut are integrally connected.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention, through the optimized connection of the motor and encoder, enables high-precision control of the mold height adjustment in the steam chamber of the vulcanizing machine. This allows for more efficient replacement of tire molds of different heights during the vulcanization process, enabling the vulcanization of tires of various specifications. Consequently, it ensures the dimensional accuracy and quality stability of rubber products, and reduces product defects and defect rates caused by mold height adjustment errors.

[0019] This invention connects the encoder shaft and the motor shaft through a pair of high-precision gears. Gear transmission enables speed and torque conversion, making it suitable for applications requiring adjustment of speed and torque. Therefore, it offers the following advantages: a. High flexibility: Speed ​​and torque can be adjusted via the transmission device to adapt to different working requirements; b. Good buffering performance: The transmission device can absorb some vibration and impact, protecting the encoder and motor; c. Easy maintenance: Replacement and maintenance of the transmission device are relatively simple and do not affect the main structure of the encoder and motor.

[0020] This invention employs a high-precision encoder and connects tightly to the motor via an optimized detachable connecting rod and reducer. This connection method ensures accurate feedback from the encoder on the motor's speed and position, thereby achieving high-precision control of the mold height. Compared to traditional motor drive systems, this significantly improves the control accuracy of the mold height, effectively solving product quality problems caused by insufficient precision in traditional methods. This invention utilizes gear transmission to adjust speed and torque, offering greater flexibility and adaptability. Through the optimized connection structure described above, it enables precise control of the mold height in the vulcanizing machine's steam chamber, improving the quality and production efficiency of rubber products.
