When the material lifting and mixing shaft 62 is driven to rotate, the four stirring blades 82 move around the periphery of the material mixing and receiving barrel 7, and in the moving process, materials on the moving route can be stirred to move out of order, so that the mixing effect is formed.
The stirring blade 82 of the present embodiment is provided with a front end in the stirring direction lower than a rear end in the stirring direction. Thus, when the stirring blade 82 moves, the stirring blade stirs the material to be inclined to the upper part of the material separation conical plate 21, so that the material can be enabled to move away from the material lifting and feeding port 61, the time for the material to enter the material lifting and feeding port 61 is delayed, and the material is enabled to complete a better primary mixing effect in the material mixing chamber 22.
In this embodiment be equipped with on the compounding urceolus 2 with clout blowing device 5 that buffer memory room 23 corresponds, when the blow molding processing finishes, when throwing away remaining material in buffer memory room 23, clout blowing device 5 can be emitted it, avoids it to produce the influence to the material that next blow molding used. The structure of the remainder discharging device 5 is similar to the structure of the feeding and discharging device 4 in this embodiment, and is easily understood by those skilled in the art according to the structure of the feeding and discharging device 4, and is not described herein again.
In use, the material lifting and mixing shaft 62 is driven to rotate and then a plurality of bulk materials are simultaneously fed into the mixing chamber 22. The stirring device 8 is arranged in the mixing chamber 22 to mix the bulk materials fed simultaneously for the first time, and the materials after the first mixing are guided downwards by the taper of the material separating conical plate 21 and enter the material lifting and mixing barrel 6 from the material lifting and feeding port 61. The material lifting and mixing blade 63 sequentially extracts the three materials from the material lifting and feeding port 61 to form mixing and lifting. In the lifting process, due to the spiral advancing path, the friction effect of the material lifting and mixing blade 63, the material lifting and mixing shaft 62 and the material lifting and mixing cylinder 6 and the like, the materials are subjected to local disordered movement and are lifted in a spiral shape integrally, and secondary mixing is realized in the lifting process. The lifted materials overflow from the top end of the material lifting and mixing barrel 6 and are scattered into the material mixing and receiving barrel 7, and the scattered orderliness forms a three-time mixing effect. And finally, the material enters the buffer chamber 23 through the material receiving and dropping barrel 71 for temporary storage. When materials are added into the subsequent mixing chamber 22, all the bulk materials are added in proportion at the same time, and continuous mixing and blanking to the buffer chamber 23 can be realized in the embodiment. When the material needs to be fed, the feeding and discharging device 4 is opened, and intermittent feeding and discharging can be realized according to the requirement.
This embodiment is through the cubic mixture for bulk material misce bene. The buffer chamber 23 is arranged so that the mixing and feeding are more effectively connected, and the embodiment can better adapt to the blow molding production of continuous extrusion blow molding.
The basic principles, main features and advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
