Description

Plastic recycler {apparatus for reclaiming plastic materials}

The present invention relates to a plastic recycling apparatus, and more specifically, to a compact structure is integrated so that the pulverization, selection and dust collection can be performed at the same time, and further can discharge fine dust and powder from the pulverized plastic falling at the same time as the crushing The defect rate can be almost eliminated by completely removing the fine dust and powder, and also the iron can be completely removed to prevent the clogging of the nozzle of the injection molding machine. The present invention relates to a plastic recycling apparatus.

In general, in order to regenerate plastic, it is pulverized by using a pulverizer, and the pulverized plastic is collected as dust and powder to be removed again, and then used as a regenerated plastic raw material.

However, as above, crushing, picking and dusting are separated, so that separate work and transportation must be performed, and it is difficult to completely remove fine dust and powder, so that the defect rate is high. Particularly, the nozzle of the injection machine is clogged by iron. This will cause a problem that will cause more injection failure.

Therefore, the present invention is to solve this problem, both integrated and detachable, integrated or detachably combined so that crushing, selection and dust collection at the same time in a compact structure, further fine from the crushed plastic falling at the same time as the crushing Dust and powder can be discharged, fine dust and powder can be completely removed, and the defect rate can be almost eliminated. Also, iron can be completely removed to prevent nozzle clogging of the injection molding machine, thereby reducing injection failure rate. The object is to provide a plastic recycling apparatus.

Hereinafter, preferred embodiment (s) of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of a plastic recycling apparatus having a unitary body according to an embodiment of the present invention, the front side with its side, and Fig. 2 is a longitudinal cross-sectional view of FIG.

1 and 2, the plastic recycling apparatus according to the embodiment of the present invention is configured in one piece, and the grinding device 10 and the line pick-up dust collecting device 20 are installed above and below the frame 50. The frame 50 has a pulverization device 10 and a dropping hole 52 for dropping the pulverized plastic is installed on one side so that the crushing device 10 and the fine dust collector 20 is installed up and down. The upper plate 51 is formed, and further below the upper plate 51 so that the line pick-up dust collector 20, the dust collecting means 60, and the recycled plastic collecting means 70 can be installed below the upper plate 51. A plurality of legs 53 and the support member 54 is installed. The leg 53 and the support member 54 may be configured in various structures in addition to the structure shown in the drawings. For example, as shown in FIG. 3, a frame provided with only a plurality of legs 53 on the top plate 51 so that the line pick-up dust collector 20 is detachable to the position shown by the dashed line below the top plate 51 ( The selection dust collector 20 may be configured to be separated by being installed on the support member 54a separated from the 50 and supported by the plurality of other legs 53a. In FIG. 1, reference numeral 15 denotes an electrical operation and control panel.

In FIG. 1, the grinding apparatus 10 includes a cutter rotating through a motor 14, a speed reducer 13, and a rotary connecting shaft 12 in order to grind the recycled plastic introduced into the input hopper 16 ( 11) is installed, and the plastics injected by the cutter 11 is crushed. The reducer 13 may be unnecessary at high speeds.

As shown in FIGS. 1 and 2, the line pick-up dust collecting device 20 includes vibration applying means 21 such as a vibrator supported by the support member 54 of the frame 50 and vibration applying means 21 thereof. Vibration oscillation is transmitted to the oscillation by vibrating alignment / transport means 22, the vibration alignment / transport means 22 is fixed to the intermediate screen 24 and the lower portion of the intermediate screen 24 It consists of a lower plate 23 that is installed shorter than the middle screen 24 in a vibrating relationship.

With this arrangement, according to the vibration alignment / carrying means 22, fine dust and powder except for recycled plastic particles in the pulverized plastic falling on the intermediate screen 24 through the drop hole 52 by the applied vibration. By passing through the bottom, the recycled plastic particles, fine dust, and powder are separated and transported from the intermediate screen 24 and the lower plate 23, respectively, and separated and dropped at each end thereof.

Thus, dust collecting means 60 and recycled plastic collecting means 70 for collecting or collecting and packing fine dust and powder and regenerated plastic particles falling from respective ends of the lower plate 23 and the intermediate screen 24. ) Is installed at each end of the lower plate 23 and the intermediate screen 24, the dust collecting means 60 and the recycled plastic collecting means 70, so that the packaging can be easily installed and removed in FIG. The basic frame is a separately installed structure, but can be configured in various ways, without being limited to this, may be a transport means such as air transport means or a manual storage container of the self-contained to simply collect dust or recycled plastic, In this case, the height of the legs can be lowered and the overall height can be reduced.

In addition, it is preferable that the pulverized plastic guide means 30 is installed on the lower surface of the upper plate 51 around the circumference so as to prevent scattering of the pulverized plastic falling from the drop hole 52. In addition, dust removal such as a suction fan or a vacuum pump is removed to remove dust or powder scattered through the connecting pipe 31 on one side of the pulverized plastic guide means 30 and / or the vibration alignment / carrying means 22. It is preferable to comprise the means 32 and the discharge pipe 33 because it is possible to remove more scattering dust and dust.

In addition, as shown in Figs. 1 and 2, the magnet means 25 at the lower end of the intermediate screen 24 to completely remove iron in the recycled plastic particles falling from the end of the intermediate screen 24. It is preferable that this is installed, and furthermore, a roller 55, preferably a fixable roller, is provided at the lower ends of the legs 53 and 53a so as to facilitate the movement of the plastic regeneration device and / or the dust collector 20 of FIG. It is preferable to install.

According to the plastic recycling apparatus described above, in an integrated or detachable structure, pulverization, selection, and dust collection can be performed at the same time, so that no additional work is required, and productivity can be greatly improved. In addition, fine dust and powder are simultaneously discharged from the pulverized plastic falling at the same time as the pulverization, which makes it possible to more effectively remove the fine dust and dust, and furthermore, there is no defect rate at all. In addition, when the magnet is attached, the iron powder can be completely removed during the operation to prevent the clogging of the nozzle of the injection molding machine, thereby reducing the injection failure rate.

In addition, it is also possible to install a plurality of intermediate screens 24 with different drop points for selection of various particle sizes, in the case of a separate type, separate the crushing device 10 and the selection dust collector 20, if necessary separately, respectively It is usable and is more convenient.

According to the configuration and operation of the plastic recycling apparatus according to the embodiment of the present invention described above, both integrated and detachable, integrally or detachably coupled so as to be pulverized, selected and collected at the same time in a compact structure, furthermore, At the same time, the fine dust and powder can be discharged from the falling crushed plastic, and the fine dust and powder can be completely removed to almost eliminate the defect rate, and also the iron can be completely removed to prevent the clogging of the nozzle of the injection machine. This can reduce the injection failure rate accordingly.
