Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for reusing resources by reusing waste from ears, unnecessary plastic bags and vinyl sheets, which can be obtained from inflation tubes generated by a bag making machine. The present invention relates to a crushing device for a vinyl sheet, a bag, or the like, which is used.

[0002]

2. Description of the Related Art Ear clogs, which are conventionally used to obtain sheets from inflation tubes generated by a bag making machine, and unnecessary plastic bags and vinyl sheets, when used again, are extruded once. It is put into a machine and melted at a high temperature, and the melted material is cut to produce pellets. Then, the pellets are mixed with pure synthetic resin granules as a recycled resource and charged into an extruder, and an inflation tube is generated by a bag making machine.

[0003]

However, such means have the following problems. 1) When heat treatment is performed at a high temperature, thermal degradation proceeds and oxidation occurs to destroy strong molecular bonds, making it difficult to recycle resources many times. In addition, regenerated resources have various oxidation states, such as those exposed to the weather and those stored indoors.If such a material is blown with a bag making machine, a hole is opened in the tube and continuous operation is performed. Will be forced to stop. This means that, for example, when blowing at a rate of 60 m / min, a large number of defective products are generated, production costs are increased, and resources are no longer available for reuse. 2) When reclaimed resources are melted by an extruder, the extruder itself is not only expensive, but also requires a large amount of electric power, which is not very desirable for reusing resources. 3) Various devices related to this need to be prepared for cutting into pellets. The present invention has been made in view of the above points, and aims at eliminating the need to use an extruder, generating pellets, and exposing to oxidization because it is not exposed to high temperatures. It is an object of the present invention to provide a crushing device such as a vinyl sheet or a bag, which has various advantages such as being less likely to be reused and being recyclable many times.
