Problems solved by technology

[0003] The above-mentioned prior art only mixes materials by means of rotating blades, but the plastic has a high viscosity coefficient in a hot-melt state and has strong viscosity, so when the blades rotate, the plastic will stick to the blades, resulting in uneven mixing Happening

Embodiment

[0025] see Figure 1 to Figure 5 , the present invention provides a technical solution:

[0026] A molten plastic mixing device, comprising a mixing tank 1, a feeding mechanism 2, a mixing mechanism 3, a driving mechanism 4 and a support shaft 5, wherein:

[0027] The support shaft 5 is installed in the mixing tank 1 in rotation, and the feed mechanism 2 is arranged on the top of the support shaft 5. The feed mechanism 2 includes a feed pipe 21, a spring 22 and a push rod 23 that are open at both ends. The pipe 21 is installed on the support shaft 5 by the spring 22, and the feed pipe 21 is installed eccentrically on the support shaft 5, and the discharge ports at both ends have different distances from the center of circle of the support shaft 5, and then when the feed pipe 21 rotates, its The outlets at both ends can be discharged to different distances, and the side of the feed pipe 21 is provided with a push rod 23, the central axis of the push rod 23 and the central axis...

Abstract

The invention provides a molten plastic mixing device. The device comprises a mixing barrel, a feeding mechanism, at least two mixing mechanisms, driving mechanisms and a supporting shaft, wherein the supporting shaft is rotatably mounted in the mixing barrel, the feeding mechanism is arranged at the top of the supporting shaft, and the at least two mixing mechanisms are arranged in the mixing barrel. Each material mixing mechanism comprises two rotating discs which are in butt joint with each other, circular baffles, discharging holes, material mixing cavities, stirring rods and torsional springs, and the two driving mechanisms are used for driving the two adjacent material mixing mechanisms to rotate in opposite directions. The two adjacent mixing mechanisms are driven by the driving mechanisms to rotate in the opposite directions, so that molten plastic entering the mixing cavities flows into the next mixing mechanism under the action of centrifugal force, and the plastic flowing into the next mixing mechanism can be mixed by the stirring rods; and an additive mixed with the plastic is uniformly fused with the plastic under the action of the centrifugal force, so that the mixing effect is ensured, and the condition that the molten plastic adheres to each other to influence mixing is avoided by adopting a centrifugal mode for mixing.
