Description

Technical Field

[0001] The utility model relates to the field of silicone rubber processing, in particular to a silicone rubber processing kneading machine with an anti-blocking mechanism. Background Art

[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atoms are usually attached to two organic groups. A kneader is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high-viscosity, elastic-plastic materials. Kneaders can be used to produce silicone rubber, sealants, hot-melt adhesives, food bases, pharmaceutical preparations, etc. A kneader is a special mixing and stirring equipment. The most commonly used one is to use two Σ blades, arranged in a side-by-side tangential differential speed type, that is, one stirring paddle has a fast speed and the other has a slow speed to generate shear force. The different paddle speeds enable the mixed materials to be sheared quickly, thereby allowing the materials to be mixed evenly.

[0003] An existing silicone rubber processing kneader with an anti-blocking mechanism (application number: 202221925984.0) includes a mixing bin, a power bin is fixed on the left side of the mixing bin, a crushing bin is fixed on the upper surface of the mixing bin and near the right side, a hopper is fixed on the upper surface of the crushing bin, a drive bin is fixed on the left side of the crushing bin, a crushing mechanism for chopping silicone rubber is provided above the mixing bin, a stirring mechanism for mixing and stirring is provided inside the mixing bin, and a bin door is hinged on the front of the mixing bin. The silicone rubber processing kneading machine with an anti-blocking mechanism, when in use, puts the silicone rubber mass into the hopper, starts the crushing mechanism, and when the silicone rubber mass falls downward into the crushing bin, the silicone rubber mass can be chopped into small pieces, thereby preventing the silicone rubber mass from being too large to block the feed port. After the silicone rubber enters the mixing bin, the stirring mechanism is started to stir and mix it, which is easy to use. After the stirring and mixing is completed, the silicone rubber can be taken out by opening the bin door, which is highly efficient and more convenient to use. However, the above problem still exists. During the stirring process, due to uneven heating and insufficient stirring, and the silicone rubber raw material is generally in a high viscosity state, it is easy for the silicone rubber raw material to stick to the wall and adhere to the surface of the stirring rod, resulting in the silicone rubber raw material being easy to agglomerate, resulting in poor effect of the produced raw material.

[0004] Therefore, it is necessary to propose a silicone rubber processing kneading machine with an anti-blocking mechanism to solve the above problems. Utility Model Content
