The present invention relates to a plastic grain cutting and transporting mechanism.
The prior plastic grain cutting and transporting mechanism, as
But due to the defection of the prior mechanism design, the defects are described as the following:
First, the plastic grains in the main plastic grain-collector 14 need to be washed, therefore, most of the plastic grains contain moisture. As a result, the plastic grains can't be pulverized thoroughly only by the three cutters 2 and the anti-gliding cutters 3 and the moisture can't evaporate completely.
Second, since the moisture can't evaporate completely, the plastic grains heated to be sticky in the heating conduit still have moisture. As a result, the end products contain bubbles and miscellaneous quality. This will decrease the quality of the end quality.
Third, since the moisture can't evaporate completely, the heating conduit has to be prolonged to heat the plastic grains longer so that the moisture can evaporate completely. The whole process takes time, occupies space, and the high cost will be the result.
One inlet support 17 is installed on the front side of the plastic grain-collector 14. The inlet 18 is an opening located at the intersection between the inlet support 17 and the plastic grain-collector 14. The plastic grain-collector 14 is a circular-tank-shape container that has one rotary cutter-holding base 23, which is driven by one connected motor 22, installed at the bottom of the plastic grain-collector. Three cutters 16 for pulverization are installed on the top of the rotary cutter-holding base 23. With help from the anti-gliding cutters 21 that is installed on the inner wall of the plastic grain-collector 14, the performance of pulverization is greatly improved. The force induced by rotation of the rotary cutter-holding base 23 smoothly pushes plastic grains into the inlet 18. A pivot support 24 is installed at the left end of the inlet support 17 and is fastened onto the mounting base 11 of the plastic grain collector 14. A pivot hole, which is located on the pivot support, acts as a supporting point for the left axle end of screw conveyor 19, and makes the screw conveyor 19 stable during operation. A heating conduit 20, which is installed at the right side of the inlet support 12, heats up plastic grains. At the same time, the screw conveyor 19 that is connected to the outlet 25 transports plastic grains. The main feather is to install a tube on the right side of the main plastic grain-collector 14 connecting the second plastic grain-collector 15; the second plastic grain-collector 15 is also a circular-tank-shaped container that has one rotary cutter-holding base 28 driven by one connected motor 27. Three cutters 29 for pulverization installed on the top of the cutter-holding base pulverize the plastic grains for the first time, the plastic grains are pulverized for the second time in the main plastic grain-collector 14. The more the plastic grain-collector is, the better the cutting performance is, thus, the plastic grains are pulverized thoroughly and certainly, the quality of the end product is improved. The merit of this invention is described as the following:
First, the more the plastic grain-collector is, the better the cutting performance is. As a result, the thorough pulverization can be achieved and the moisture can be evaporated more completely. Certainly, the quality of the end product is improved
Second, since the moisture evaporates completely, the plastic grains are heated up in the heating conduit with less moisture. Moreover, the end product doesn't have any bubbles or miscellaneous quality, and certainly, the quality of the end product is improved.
Third, since the cutting performance is improved; the raw materials have less moisture. Thus, the heating conduit can be shortened half a length than the prior one. The moisture can be evaporated in the shorter heating conduit; therefore, the whole process is timesaving, economical and occupies less space.
