Detailed Description
As shown in figures 1-4, the feeding device of the film recycling extruder comprises a bin 1 connected with an extruder 6 and a compaction feeding machine bin 3. A screw conveyor 2 is arranged at the bottom of the bin 1, and a compaction feeding machine bin 3 is arranged below the discharge end of the screw conveyor 2; an outlet is arranged on the compaction feeding machine bin 3, and a cutter head 4 is arranged in the outlet; the cutter head 4 is provided with a central shaft which is connected with a compaction feeding machine motor 5; a compactor feed motor 5 is fixed to the support of an extruder 6, which extruder 6 is connected to a compactor feed bin 3.
Wherein: the central shaft is connected with an output shaft of a motor 5 of the compaction feeding machine through a belt pulley to drive the cutter head 4 to rotate at a high speed.
The side of the extruder 6 is provided with a feed inlet which is connected with the outlet of the compaction feeder bin 3.
The diameter of the cutter head 4 is 1000mm, the thickness is 40mm, the rotating speed is 400 r/min-600 r/min, and a crescent-shaped convex block is arranged on the upper surface of the cutter head.
The screw diameter of the screw conveyor 2 was 300mm and the constant rotational speed was 30 r/min.
The diameter of the compaction feeding machine bin 3 is 1100mm, and the height is 1200 mm.
The diameter of a screw of the extruder 6 is 120mm, and the length-diameter ratio is 32: 1, the highest rotating speed is 120 r/min.
The working principle is as follows: the opening or the stopping of the motor of the screw conveyor 2 is controlled by setting the current of the motor 5 of the compaction feeding machine, so that the material quantity in the bin 3 of the compaction feeding machine is controlled. When the current of the motor 5 of the compaction feeding machine exceeds a set value, the material in the bin 3 of the compaction feeding machine is excessive, the motor of the screw conveyor 2 is stopped, and the material is not conveyed; when the current of the motor 5 of the compaction feeding machine is lower than a set value, the compaction feeding machine indicates that the material in the bin 3 of the compaction feeding machine is less, and the motor of the screw conveyor 2 is started to convey the material.
The shape of the recycling film of the utility model is that the length and the width are less than 20mm, and the thickness is 12 to 200 μm.
When the device works, a thin film in the hopper 1 passes through the low-speed rotating screw conveyor 2 to the compaction feeding machine bin 3, is compacted into a roll shape by the high-speed rotating cutter head 4, and enters the extruder 6 from the side surface of the barrel of the extruder 6. An output shaft of a motor 5 of the compaction feeding machine is connected with a central shaft of the cutter head 4 through a belt pulley to drive the cutter head 4 to rotate at a high speed. The opening or the stopping of the motor of the screw conveyor 2 is controlled by setting the current of the motor 5 of the compaction feeder, so that the material amount in the bin 3 of the compaction feeder is controlled. When the current of the motor 5 of the compaction feeding machine exceeds a set value, the material in the bin 3 of the compaction feeding machine is excessive, the motor of the screw conveyor 2 is stopped, and the material is not conveyed; when the current of the motor 5 of the compaction feeding machine is lower than a set value, the compaction feeding machine indicates that the material in the bin 3 of the compaction feeding machine is less, and the motor of the screw conveyor 2 is started to convey the material.
