Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically a mixing device for processing low-smoke halogen-free cable materials. Background Technology

[0002] Low-smoke halogen-free cables are an environmentally friendly type of cable. Their insulation and sheath materials do not release toxic halogen gases when burning, and produce very little smoke. They commonly use polyolefin as the insulation layer, and add aluminum hydroxide (ATH) or magnesium hydroxide (MH) as flame retardants. When heated, they decompose, absorb heat, and release water vapor, thus inhibiting combustion. The sheath is made of low-smoke halogen-free polyolefin.

[0003] Depending on the required properties, cable materials need to go through multiple steps such as mixing, cooling, and granulation. Therefore, the mixing of raw materials is very important. After the cable materials are mixed, a small amount of cable materials will remain in the mixer. In order not to affect the next use, it needs to be cleaned, which takes a long time to clean and involves a lot of work.

[0004] Upon investigation, Chinese utility model patent CN220784500U was disclosed, which includes a mixing tank, a clamping block movably connected to the top of the mixing tank, a support plate fixedly connected to the inner wall of the clamping block, and a cleaning component movably connected inside the support plate, with the cleaning component located inside the mixing tank.

[0005] Although the aforementioned patent uses a cleaning component that rotates a rotating rod to drive a rotating component, causing the clamping block to rotate at the top of the mixing tank, and then the cleaning component to rotate to brush the inner wall of the mixing tank, the cleaning component is located inside the mixing tank. Its brush part comes into contact with the cable material, causing the cable material to adhere to the brush surface, resulting in sticking and affecting the normal brushing work. It cannot effectively clean the cable material on the inner wall of the tank.

[0006] Therefore, this utility model provides a mixing device for processing low-smoke halogen-free cable materials to solve the above problems. Utility Model Content
