Small waste PET bottle crushing device {Wasted PET Bottle Automatic Crushing device}

The present invention relates to a small-sized waste plastic bottle crushing device, and more particularly, is composed of a small size and collects waste plastic bottles in the primary collection step of general households or small-scale complexes such as schools, apartments, buildings, etc. It relates to a small waste plastic bottle crushing device that improves the collection efficiency of waste plastic bottles for the primary collection step by enabling crushing.

In general, a PET bottle is a container for containing bottled water or beverages, and is made of a PET material, which is one of plastic materials.

These PET bottles have the advantages of being easy to process due to material characteristics, enabling mass production, having good durability, long service life, light weight, easy handling and transportation, and being recyclable.

On the other hand, most of the PET bottles are made of disposable containers, and their usage is extremely large, while the recycling rate is less than 5%. Due to the disadvantage that it takes more time, it is recognized as the main culprit of environmental pollution.

However, PET bottles are positioned as daily necessities used for various purposes, so it is almost impossible to replace them and the convenience of use cannot be given up, so there is a realistic limit to reducing the amount of PET bottles used.

Due to these realistic limitations, measures for PET bottle rehabilitation that can increase the recycling rate of PET bottles instead of reducing the amount of PET bottles are being sought, and devices necessary for this are also being researched and developed.

For example, Utility Model Registration No. 20-266269 discloses a plurality of primary crushing blades and a plurality of circumferentially cutter blades formed on a drive shaft that rotates at a reduced speed by a drive motor and a speed reducer, forming a cutter at regular intervals in the axial direction A plurality of rotary cutters are alternately arranged, and fixed cutters are provided on both sides of the rotary cutters, and the cutter blades of the fixed cutters are installed between the cutter parts of the rotary cutters to be interlocked.

In addition, the rotary cutter is formed so that the cutter blades on the plurality of cutter parts are gradually mutually eccentric in the axial direction so that they are sequentially engaged with the fixed cutter, and each cutter blade of the cutter part has its shear surface in the axial direction so that the shear stress is reduced.

The fall reversal unit 220 constitutes a support bracket for partially contacting and supporting the PET bottle transferred from the transfer conveyor 210 and a reversing means for rotationally contacting both ends of the PET bottle located on the support bracket, and the support The bracket is formed so that both ends form an outwardly convex curved surface to smoothly induce an inclined fall according to the sliding contact of the PET bottle, and the reversing means is arranged at intervals left and right and is rotatably configured to correspond to both ends of the PET bottle. It constitutes a pair of contact blades and a reversing drive means for applying rotational power to the contact blades, and the contact blades are formed to protrude outward to be able to contact the PET bottle elastically, and a plurality of them are formed at intervals in the circumferential direction of the contact blades. It constitutes a rubber member formed to have.

Relative to the lower end of both ends of the PET bottle when the rubber member of the pair of contact blades is rotated by the rotational drive of the inversion driving means in correspondence with both ends of the PET bottle supplied in a state lying horizontally on the support bracket As the small upper bottle cap part comes into contact with the rubber member later, the bottle cap part of the PET bottle is tilted downward and falls vertically, and the cutting part 300 is arranged symmetrically at intervals left and right and transports the PET bottle forward. The cutting conveyor 310 that drives the cutting conveyor 310 and the clamp unit 320 installed at intervals on the cutting conveyor 310 and gripping and fixing the bottleneck portion in response to the PET bottle dropped and transported from the first transfer unit 200 and the above It includes a cutting unit 330 installed in correspondence with the transport path of the cutting conveyor 310 and driving so as to be able to cut the bottle cap portion of the PET bottle gripped and fixed on the clamp unit 320, Air spraying means 340 for spraying high-pressure air to remove foreign substances by spraying air toward the PET bottle from which the content has leaked to the bottle cap portion of the PET bottle cut through the cutting unit 330 in the transfer path is configured.

However, the above-described conventional PET bottle crushing device has a problem in that it is unsuitable for use in places where small-scale recycling PET bottles such as schools, apartments, or buildings are collected due to the enlargement of the device, and thus has limitations in use.

In addition, the conventional PET bottle crushing device must separate, sort and collect transparent or colored PET bottles, but the conventional crushing device has a problem in that recycling efficiency is lowered as separate color separation for this is not performed.
