Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a highly efficient and stable kneading machine. Background Art

[0002] Kneading machine is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high viscosity and elastic plastic materials. Kneading machine can be used to produce silicone rubber, sealant, hot melt adhesive, food glue base, pharmaceutical preparations, etc. Kneading machine is a special mixing and stirring equipment. The most commonly used is to use two paddles, arranged in a side-by-side tangent differential speed type, that is, one stirring paddle has a fast speed and the other has a slow speed, so as to generate shear force. Different paddle speeds enable the mixed materials to be sheared quickly, so that the materials can be mixed evenly.

[0003] The utility model with prior art publication number CN220389972U relates to a kneading machine with a pressing plate. A pressing plate is movably arranged under the cylinder cover. When stirring, the material is stirred in two circular cavities which are interconnected and formed by a lower arc surface and an upper arc surface. The material is squeezed in a confined space and will not flip up excessively, thereby greatly improving the stirring effect and efficiency.

[0004] However, the above device still has the following problems when in use: when the existing kneading machine is in use, most of them adopt a central bottom discharge structure design, and often adopt a single discharge port structure design, which is very easy to cause discharge blockage. At the same time, the material that is fully stirred at the periphery of the kneading machine cannot be discharged quickly. In addition, most of the existing kneading machines use a single motor reduction mechanism to drive one blade to actively rotate, and then drive the other blade to rotate passively through a belt drive equipped with the single motor reduction mechanism. The transmission ratio of the belt drive is fixed, and the differential ratio of the two blades is fixed, and the two blades cannot be flexibly driven to rotate at differential speeds.
