Description

  The present invention relates to a crushing device used for volume reduction processing of plastic bottles and the like.

  In order to recycle plastic bottles, etc., used bottles are transported to a processing plant. In that case, a bottle with a smaller form, that is, a reduced volume can be transported in large quantities at once. Moreover, the handling becomes easy. Therefore, recently, it is recommended to reduce the volume by crushing in condominiums and convenience stores where plastic bottles are discharged in large quantities, and even in ordinary households.

  However, current crushing devices such as plastic bottles crush the bottles between the relatively rotated rollers, and the apparatus becomes large because it includes two rollers. In order to bite a plastic bottle having a diameter of about 10 cm between them, a roller having a considerably large diameter must be used. As a result, the apparatus becomes large and the price is high, so that versatility is poor.

Problems to be solved by the invention

  It is an object of the present invention to provide a crushing device such as a plastic bottle that is compact and inexpensive and can be suitably used in a condominium, a convenience store, and a general household.

Means for solving the problem

  According to the present invention, the rotation form control of the crushing plate is arranged such that the crushing plate is disposed at one rotation angle and closed at the other rotation angle between the pair of crushing plates that are disposed relative to each other and coaxially rotated. A crushing device characterized by comprising a mechanism.

  According to the crushing device having the above-described configuration, the plastic bottle or the like placed between the crushing plates opened at one rotation angle is crushed by the closing operation between the other rotation angles accompanying the rotation of the crushing plate. It is. Since the crushing mechanism is composed of two crushing plates that are arranged relative to each other, its solid form is much smaller while maintaining a crushing surface area that is equal to or greater than that of conventional rollers. The device can be configured compactly.

  As the rotation driving means for the crushing plate, appropriate means such as a motor and human power are used. In addition, the crushing surface of the crushing plate is preferably provided with protrusions and ridges that dig into a plastic bottle or the like to enhance the crushing function, and in the case of ridges, the corners of the plastic bottle are crushed by biting, Prevents bulge restoration due to the elasticity of plastic bottles.

The invention's effect

  According to the present invention, it is possible to obtain a crushing device such as a plastic bottle that is compact and inexpensive and can be suitably used in a condominium, a convenience store, and a general home. Will be promoted.

  FIG. 1 is an external perspective view of the crushing device of the present invention, and FIG. 2 is an internal configuration diagram. In the crushing device 1, the upper part in the outer box 2 is a plastic bottle crushing processing unit 3, and the lower part is a collection unit 4. A folding lid 6 that covers the plastic bottle charging opening 5 is attached to the upper surface of the exterior box 1, and an operation unit 8 is provided on the front side. A recovery box 9 that can be pulled out into the recovery unit 4 is provided at the lower front side. The front plate is located, and each of the moving casters 10 is attached to the bottom surface.

  The crushing processing unit 3 is provided with a pair of metal crushing plates 12 that are relatively arranged and rotated coaxially, and a motor 14 that drives and rotates the plates. As shown in FIG. 3, the crushing plate 12 has a curved disk shape, and a plurality of crushing projections 13 are formed on the convex curved surface 15 by press molding, and the convex curved surfaces 15 are opposed to each other. In this way, the shaft body 16 is interlocked with the motor 14. The shaft body 16 includes a spherical portion 19 at the center position, and the spherical curved surface 20 of the bearing portion 17 integrally provided at the center position on both sides thereof matches the spherical portion 19 surface of the crushing plate 12. Each is attached.

  Each of 22 is a coil spring that presses each of the crushing plates 12 toward the center, and each of 23 is a fixed seat thereof. Positioning rollers 25 as rotation mode control mechanisms of the crushing plate 12 are provided so as to rotate in contact with the crushing plate 12 surface at positions corresponding to the lower outer surfaces of the crushing plate 12. Yes.

  With the above-described configuration, each of the crushing plates 12 is pressed and fixed to the shaft body 16 side at the bearing portion thereof, so that the crushing plate 12 rotates together with the shaft body 16 as the motor 14 is driven. Are positioned so as to be sandwiched from both sides by the positioning roller 25, so that when they are positioned upward during rotation, a receiving space 30 is formed which is separated from each other and continues to the charging opening 5 therebetween, and is positioned below. When they do, they work close together and crush the plastic bottle between them.

  Hereinafter, the operation of the crushing device 1 will be described. As shown in FIG. 1, when the folding lid 6 is opened and the plastic bottle P is inserted into the input opening 5 and the start switch is pushed by the operation unit 8, the input plastic bottle P has a funnel-like groove shape. As a result, it falls horizontally and falls into the receiving space 30 between the crushing plates 12. The crushing plate 12 is crushed while the crushing projections 13 are biting into the plastic bottle P by gradually narrowing the space between the crushing plates 12 in the direction of the arrow A, and the plastic bottle P is in the lower position. When crushing, completely crush. Further, as the rotation continues, the portion of the crushing plate 12 sandwiching the plastic bottle P is gradually separated, and the flattened plastic bottle P is moved downward from between the crushing plates 12. It falls and is stored in the collection box 9. When a plurality of plastic bottles P are charged, the above operation is continuously performed and the flat bodies are sequentially stored in the collection box 9.

  As described above, the volume-reduced product in which the plastic bottle P is crushed is recovered in the recovery box 9 only by being input from the input opening 5. Since the crushing operation is performed inside the apparatus with the folding lid 6 closed, there is no loud noise and there is no danger.
