The defective bottle blanks slide down through the arc-shaped channel 114, slide into the second feeding hole 131 from the first discharging hole 113, fall on the conveyor belt 141, and are changed from an initial vertical state to a horizontal state. The second motor 142 drives the conveyor belt 141 to move, so as to move the defective bottle blanks from the second feeding hole 131 to the second discharging hole 133. When the defective bottle blank moves to a position below the second cutter set 151, the third motor 152 drives the second cutter set 151 to rotate, so as to cut along the radial direction of the defective bottle blank, thereby cutting the defective bottle blank into granules.

Specifically, some defective products that cannot meet the shipping requirements are inevitably generated during the production process of the bottle preform. The bottle blank granulating, mixing and feeding machine provided by the invention can be used for immediately recycling the uncontaminated defective bottle blanks while producing the bottle blanks. Firstly, a worker vertically drops a defective bottle blank into the first cutting chamber 112 from the first feeding port 111, the defective bottle blank falls into a cutting channel formed by four first cutter disc groups 121 due to the self gravity, and the first cutter disc groups 121 are driven by the first motor 122 to perform first cutting along the axial direction of the bottle body of the defective bottle blank. The defective bottle blanks after the first vertical cutting continuously fall into the arc-shaped channel 114 downwards, slide to the first discharge port 113 through the channel 114, and slide to the conveyor belt 141 through the second feed port 131 butted with the first discharge port 113. At this time, the defective bottle preform is horizontally placed on the conveyor 141. The second motor 142 drives the conveyor belt 141, the conveyor belt 141 transports the defective bottle blanks to the third discharge port 213, and passes through the second cutter set 151, and the third motor 152 drives the second cutter set 151 to rotate, so as to radially cut the defective bottle blanks. The flaw bottle blank which is cut twice in the axial direction and the radial direction is cut into regenerated particles which are similar to the specification of the raw material and have uniform particles. The regenerated particles with uniform particles can effectively avoid the phenomenon of white fog caused by nonuniform drying and heating before the new bottle blank is used for injection molding due to different sizes of the particles. The regenerated particles fall into the mixing box 21 through the fourth feed port 212 connected to the third discharge port 213 by gravity, and at the same time, the raw material is fed into the mixing box 21 from the third feed port 211 by a worker. The fourth motor 222 drives the agitator 221 to mix the raw material and the regenerated particles in the mixing box 21, and the uniformly mixed particles are used as the raw material for the next injection molding process.
In summary, the bottle preform grain-cutting mixing feeder provided by the invention directly recovers the defective bottle preforms generated in the production process of the bottle preforms, cuts the defective bottle preforms twice in the axial direction and the radial direction through the cutting assembly, mixes the regenerated particles obtained by cutting with the input raw materials, and uses the mixed particles for injection molding of new bottle preforms. In the process of producing the bottle preform, the defective product produced in the production process is directly recovered, and the bottle preform is put into production immediately after being treated, so that the loss of raw materials is reduced, the utilization rate of the raw materials is improved, the resources are saved, and the production cost is reduced.
