Description

Technical Field

[0001] The utility model relates to the technical field of rubber vulcanization, in particular to a vulcanization heating roller. Background Art

[0002] Rubber vulcanization refers to the process of adding additives such as vulcanizers and accelerators to rubber to transform the linear macromolecules of rubber into a three-dimensional network structure under a certain pressure and temperature. This can significantly improve defects such as low strength, easy aging and poor elasticity of rubber. The rubber will be heated during the vulcanization process, and a vulcanization heating roller will be used at this time.

[0003] A Chinese patent with publication number CN208164122U discloses a vulcanization heating roller, including a roller, a condenser and an air inlet. The air inlet is used to fill steam into the roller to heat the roller, and the water vapor in the roller is cooled by a cooling tube, thereby controlling the temperature in the roller to be kept within a certain range.

[0004] However, adjusting the temperature by condensing the hot steam will cause a large amount of high-temperature water to appear in the drum. Since the heating roller is mostly made of iron metal, a large amount of high-temperature water will accelerate the corrosion of the roller material and reduce the service life of the equipment. Utility Model Content

[0013] 1. The utility model arranges an air pipe in the roller, and controls the opening size of the air outlet holes on the air pipe by the first baffle in the air pipe. When heating, the air outlet holes are fully opened, so that the roller can be heated quickly. When keeping warm, the baffle is rotated to reduce the opening of the air outlet holes, so that the temperature in the roller is kept within a certain range, and there is no need to control the temperature by condensing steam, thereby reducing the generation of condensed water;

[0014] 2. The utility model has a first air inlet and a second air inlet arranged in the middle of the end cover. The first air inlet is connected to hot steam, and the second air inlet is connected to normal temperature air.

[0022] Specifically, two arc-shaped baffles 36 are slidably provided in the through groove 311, and the curvature of the through groove 311 is greater than 135 degrees and less than 180 degrees. Two levers 35 pass through the two arc-shaped baffles 36 respectively, and the levers 35 are connected and fixed to the corresponding arc-shaped baffles 36 to realize the sliding of the levers 35 in the through groove 311. A sealing gasket is provided between the arc-shaped baffle 36 and the end cover 31 to ensure a certain degree of sealing.

[0023] Specifically, the air outlet 32 ​​is located in the roller 1, and the width of the end surface of the first baffle 34 is greater than or equal to the inner diameter of the air outlet 32, so that the air outlet 32 ​​can be completely blocked and the adjustment range can be increased.

[0024] Specifically, the guide plate 37 disposed on the outer wall of the air pipe 3 and between two adjacent exhaust holes 32 can guide the airflow to the inner wall of the roller 1, thereby further improving the heating effect of the steam.
