Abstract

PURPOSE:To obtain a PET bottle shredder small in size and simple in structure by discharging air in a PET bottle from which a stopper is removed, collapsing it into a platelike shape and shredding the collapsed PET bottle. CONSTITUTION:The PET bottle 3 from which the stopper is removed is charged into a shredder 1. A packing 7 of a collapsing part 4 is closely fitted to an opening 10 of the charged PET bottle. When a vacuum pump 9 is driven, the air in the PET bottle 3 is sucked via a sucking pipe 8 communicated to the inside of the PET bottle through the packing 7 to collapse the PET bottle into a platelike shape. The collapsed PET bottle 3 is dropped downward when driving of the vacuum pump 9 is stopped, and is transferred to a shredding part 5. At this time, since a gear motor 12 is rotated, when the collapsed PET bottle 3 drops between rotary tooth groups 11, 12, the rotary tooth groups 11, 12 bite the PET bottle 3, the and PET bottle is shredded by each rotary tooth 23 and is stored in a container 6.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PET bottle shredder which is formed from polyethylene terephthalate resin and is used for filling soft drinks and the like.

[0002]

2. Description of the Related Art Various kinds of soft drinks are filled in the PET bottle and sold. When recycling a used PET bottle, it is necessary to shred or crush the PET bottle. On the other hand, the PET bottle has a substantially cylindrical shape, and has a problem that it is difficult to crush it as it is. Moreover, although a large plant for crushing a large number of PET bottles is used, a small device capable of shredding or crushing PET bottles one by one has not been obtained. Therefore, a large-sized apparatus is required to process the PET bottle, and a small-sized apparatus having a simple structure has been desired.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and an object thereof is to provide a PET bottle shredder having a small size and a simple structure.

[0004]

The PET bottle shredding machine of the present invention is a shredding machine for shredding a PET bottle formed of polyethylene terephthalate resin, and the mouth of the PET bottle to be thrown in after removing the stopper. The PET bottle has a flat plate shape, and a close contact member that is attached in close contact with the PET bottle and an air discharge unit that is provided in communication with the close contact member inside the PET bottle and discharges the air inside the PET bottle. Crushing means for crushing into pieces, shredding means for shredding the crushed PET bottle, and the P shredded by the shredding means
A container for accommodating strips of ET bottles,
Thereby, the above object can be achieved.

In the present invention, the shredding means may consist of a plurality of rotary blade groups facing each other.

[0006]

In the PET bottle shredding machine of the present invention, the PET bottle is put into the shredder with the stopper removed. In the introduced PET bottle, the close contact member of the crushing means is attached so as to be in close contact with the mouth of the PET bottle, and the PET discharge is provided by the air discharge means provided in communication with the inside of the PET bottle.
The air inside the bottle is discharged, and the PET bottle is crushed into a flat plate shape. The crushed PET bottle is shredded by shredding means, and the shredded pieces of the PET bottle are
It is stored in a storage container.

The PET bottle shredder having such a structure is
It has a small size and a simple structure and is extremely easy to use.

1 is a cross-sectional view of a PET bottle shredder (hereinafter referred to as shredder) 1 according to an embodiment of the present invention, FIG. 2 is a perspective view of a crushing section 4, and FIG. 4 is a side view of the shredded portion 5, FIG. 4 is a front view of FIG. 3, and FIG. 5 is a plan view of FIG. With reference to these drawings, regarding the present embodiment,
explain. The shredder 1 of the present embodiment is made of polyethylene terephthalate resin, and the PET bottle 3 having the stopper removed is put therein to shred the PET bottle 3. The shredder 1 has a crushing section 4, and the crushing section 4 is, as shown in FIG. 2, a packing 7 closely attached to the mouth 10 of the PET bottle 3 that has been put in, and a packing 7
And a suction pipe 8 communicating with the inside of the PET bottle 3. This suction pipe 8 is connected to a vacuum pump 9.

A shredding section 5 for shredding the PET bottle 3 shredded by the shredding section 4 is provided below the shredding section 4, and further below the shredding section 5 with the shredding section 5. A storage container 6 for storing the broken pieces of the PET bottle 3 is provided.

As shown in FIGS. 3 to 5, the shredder portion 5 is composed of a plurality of rotary blade groups 11 and 12 facing each other. The shredded portion 5 includes a gear motor 13, and the gear motor 13 includes a rotary shaft 14 to which the rotary blade group 11 is fixed.
Is meshed with a gear 15 fixed to one end of the. Gear 1
5 is meshed with a gear 17 fixed to one end of a rotary shaft 16 to which the rotary blade group 12 is fixed. Each rotating shaft 1
Both ends of 4, 16 are rotatably supported by the bearings 18, 20, 21, 22, respectively, on the frame 18 in the housing 2. Each rotary blade group 11, 12 has a plurality of rotary blades 23 arranged with a gap therebetween. The rotary blade group 1 facing the gap between the rotary blades 23 of the rotary blade group 11
Each rotary blade 23 of 2 is arranged.

The operation of the shredder 1 will be described below. The PET bottle 3 with the stopper removed is put into the shredder 1. In the mouth 10 of the PET bottle 3 that has been thrown in,
The packing 7 of the crushing section 4 is attached in close contact. When the vacuum pump 9 is driven, a suction pipe 8 penetrating the packing 7 and communicating with the inside of the PET bottle 3
The air in the PET bottle 3 is sucked through the
The bottle 3 is crushed into a flat plate shape.

The crushed PET bottle 3 drops downward when the driving of the vacuum pump 9 is stopped, and reaches the shredded portion 5. At this time, the gear motor 12 is rotating. When the PET bottle 3 crushed in the flat plate shape falls between the rotary blade groups 11 and 12, the rotary blade groups 11 and 12 satisfactorily bite the flat PET bottle 3 and each rotary blade 2
3, the PET bottle 3 is shredded. The strips of the PET bottle 3 shredded by the shredder 5 are stored in the storage container 6.

As described above, in the present embodiment, the PET bottle shredder 1 having the above-described structure has a small size and a simple structure, and has an advantage of extremely high usability.
