The internal mixing device is suitable for the technical field of internal mixing devices.

Description

technical field [0001] The invention belongs to the technical field of banburying devices, in particular to a banburying device for low-temperature-resistant sealing materials and a control method thereof. Background technique [0002] Low-temperature resistant sealing materials mainly refer to rubber sealing materials suitable for low-temperature environments. Rubber materials are mainly mixed and formed through internal mixers. During the mixing process, various additives need to be added to improve the overall performance. [0003] Recently, according to the investigation of the actual use of internal mixers, people have gradually realized that during the internal mixing process, applying a floating pressure that can be automatically adjusted to the rubber material to be mixed in the internal mixing chamber can significantly improve product quality.

Problems solved by technology

[0003] Recently, according to the investigation of the actual use of internal mixers, people have gradually realized that during the internal mixing process, applying a floating pressure that can be automatically adjusted to the rubber material to be mixed in the internal mixing chamber can significantly improve product quality. And greatly improve production efficiency; that is to say, the pressing mechanism device has become a key component that directly affects the working efficiency and product quality of the internal mixer; at present, the floating control of the pressing device is usually controlled by hydraulic or pneumatic control, but the structure of the hydraulic device is more complex. Complicated, and the pneumatic device is noisy, so it needs to be improved;

[0004] In addition, the existing internal mixing device is usually manual batching, which has problems such as slow measurement speed, large human error, and poor measurement accuracy, which seriously affects production efficiency and product quality.
