Different materials leaves in the hopper in advance, and material gets into the mixing of materials storehouse through charging aperture from hopper, and fills up the space (having partial material directly directly to see off from discharging opening when beginning certainly) in mixing of materials storehouse; Because the hand of spiral of forward thread segment and reverse thread section is opposite, drive unit drives feeding spiro rod and presses the certain orientation rotation, and forward thread segment and reverse thread section all promote material makes material carry toward middle from the feeding spiro rod two ends; The feeding speed of forward thread segment and reverse thread section is set to the discharging speed greater than discharging opening, when material converges in the centre since from two ends to the extruding force effect of centre; Partial material is seen off by discharging opening; Another part material upwards arches upward, and rises gradually, when the material that arched upward reach a certain height; Just disperse toward two ends, thus the mixing of completion material one-period.Can find out that from the above-mentioned course of work pressure pay-off of this band mixed function can be realized the mixing and the conveying of material, promptly is that mixing of materials device and device for transporting objects are closely linked, structure is quite compact, and it is little to take up room, and economizes the land resource; On the other hand, owing to send into process equipment by discharging opening immediately after the mixing of materials, do not have middle conveying process, material can layering, thereby has improved the processing quality of goods afterwards; In addition, because when mass transport is obstructed, the amount of the material of down carrying can reduce, and the amount of the material that mixes of up arching upward can increase, and can effectively avoid causing problems such as drive unit overload because of transmission failure produces the transporting resistance increasing.
Preferred version as the utility model is characterized in that: comprise that also bleeder valve, bleeder valve are installed on the said discharging opening.Before the feeding, close bleeder valve earlier, carry out the premixed of material, when mixing of materials is even, just open bleeder valve and begin feeding, make the material of seeing off for the first time just reach the uniformity requirement of mixing, further improved the qualification rate of goods.
Preferred version as the utility model is characterized in that: said mixing of materials storehouse is a tubular.The mixing of materials storehouse is set to tubular, is more conducive to material and carries to the centre from the two ends in mixing of materials storehouse, makes the material of in the middle of two side direction, carrying have stronger extruding force, thereby obtains better mixing of materials effect.
The utility model compared with prior art; Have following beneficial effect: forward thread segment and reverse thread section all promote material and mix toward the middle feeding and the completion of arching upward; On same device, realizing the mixing and the conveying of material, promptly is that mixing of materials device and device for transporting objects are closely linked, and structure is quite compact; It is little to take up room, and economizes the land resource; On the other hand, owing to send into process equipment by discharging opening immediately after the mixing of materials, do not have middle conveying process, material can layering, thereby has improved the processing quality of goods afterwards.
