Stirring mechanism

Abstract

The invention relates to a stirring mechanism, which comprises a transmission main shaft, the transmission main shaft is provided with a spiral blade and a stirring blade, and the spiral blade is usedfor propelling the fiber and a base material, the mixing blade is used to mix the fiber and the base material, the stirring blade can quickly cut and break the material during a mixing process, so that the uniformity and dispersion of a mixture can be greatly improved, the stirring blade has the advantages of fast mixing speed, high efficiency, high fiber filling rate, convenient use and maintenance, and low maintenance cost; the spiral blade effectively prevents clogging and accumulation in a fiber feeding process, the feeding speed is fast, and the feeding is smooth.

Description

technical field [0001] The invention relates to a stirring mechanism, in particular to a stirring mechanism with high stirring efficiency, which belongs to the field of mechanical technology. Background technique [0002] Fiber Reinforced Polymer (or Fiber Reinforced Plastic, referred to as FRP) is formed by reinforcing fiber materials, such as glass fiber, carbon fiber, aramid fiber, etc., and matrix materials through winding, molding or pultrusion. composite material. According to different reinforcing materials, common fiber reinforced composites are divided into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP) and aramid fiber reinforced composites (AFRP). [0003] The production process of fiber-reinforced composite materials needs to use a blender. The blender generally includes a feeding bin and a mixing bin. The interior of the mixing bin is equipped with a transmission shaft, and a stirring blade is set on the transmission shaft, ...

Problems solved by technology

[0004] The mixing blades on the transmission shaft of the traditional blender’s mixing chamber cannot break and mix the materials quickly. The uniformity and dispersion of the materials are poor, the mixing speed is slow, and the mixing efficiency is low, resulting in low fiber filling rate. The mixing blade wears out quickly and is not easy to replace;

[0005] At the same time, the high-speed rotating drive shaft drives the stirring blades to stir the fibers and matrix materials. During the stirring process, a large amount of heat is generated. Because the large amount of heat cannot be removed in time, the temperature of the drive shaft rises too fast, seriously exceeding the bearings at both ends of the drive shaft. When the temperature rises to a certain level, it will cause the rolling bodies of the bearings at both ends to freeze and the inner and outer rings to lock, which will seriously affect the service life of the bearings.

[0006] In addition, due to the characteristics of the fiber itself, during the process of a large amount of fiber entering the mixing bin from the feeding bin, because the traditional blender has no material pushing device, the fibers are easy to accumulate in the mixing bin, the feeding speed is slow, and a large amount of fiber The clogging of the mixing blades will easily cause the shutdown of the mixing blades, which will accelerate the wear of the mixing blades and increase the production cost.
