The Related Art

Invention relates to a recycling machine in general of plastic recycling; which consisting of respectively, shredder, extruder, melt filter and pelletizing modules; and providing recycling by converting industrial wastes including production waste, edge trims, faulty production and over production waste plastic materials into granules.

The invention particularly relates to a recycling machine providing a supply of industrial waste plastic materials into an extruder after shredding by the integrated shredder and a transfer of shred waste plastic by means of automation controlled mechanical embodiment and consisting of single type, side by side double type and one on another double type boxer pusher module according to type of materials in process.

Prior Art

Today there are machines providing transformation of production waste, edge trims, faulty production and overproduction waste plastic materials which are industrial wastes, into granules in plastic recycling. Shredder and extruder screw of those machines are driven by the same drive at the same rotation speed. The structure of order of blades on the shredder is helical and continuation of shredder rotor is in form of screw of the extruder. In such machines feeding shred plastics from shredder into extruder is provided by direction of material shred at shredder into extruder on one single axis through helical motion. Plastic is heated, compressed and melted by means of screw-barrel embodiment and heaters surrounding barrel. The product passing through melt filter and pelletizing processes in the next step becomes granule. Problems are encountered in process stages because of such way of supply of shred waste plastics from shredder to extruder.

Stable material feeding according to the type of industrial waste is not achieved correctly with this system of the Prior Art. For instance, while processing industrial waste plastic in film form (plastic bags, packaging waste etc.) as shredder rotor and extruder screw are rotating at same speed, extruder speed is too much for the operation. For that reason, the amount film materials passing to the extruder from shredder are not adequate to feed extruder and since it is not possible to reduce screw speed independent of shredder rotor speed, granulate quality of film materials conveyed to extruder is low and loss occurs in time. Another example, while processing industrial waste plastic in thick rigid form (crate, pallet, pipe etc.) as shredder rotor and extruder screw are rotating at same speed, extruder speed is too low for the operation. Since it is not possible to increase speed of extruder screw independent of shredder rotor speed, thick rigid plastic is too much for extruder. As a result, granulate quality of thick rigid material conveyed to the extruder is low. In addition, too many times shred thick rigid material on rotor melts and wraps around the shredder rotor. Since it is very difficult to process thick rigid industrial waste plastic at such types of machines, it is not preferred to process thick rigid materials at this type of machine. Because of such deficiency, machines of different features as per material type are to be produced.

Since in the related art speed of shredder and screw is same and it is not likely to increase and decrease extruder screw speed independently. As extra amount of plastic that can’t pass to the extruder screw, remains on the shredder rotor for a long time, that plastics reach melting temperature on the rotor and starts to melt, covers the shredder blades and rotor, makes shredding difficult and degrade product quality. It causes high energy consumption and low capacity. This method of feeding shred industrial waste plastics to the extruder prevents stable operation of the machine and since much product is supplied to the shredder and shredder does not have chamber to collect extra materials, extra shred materials melts on the rotor. This method of supplying industrial waste plastic material to extruder makes use of machine difficult It does not allow stabilizing output capacity according to the type of post-industrial waste to be processed.

In the related art since there is no automatic feeding control system when the machine is loaded with extra products by the operator, industrial waste plastic melts on the shredder rotor before reaching extruder and wraps around shredder rotor and damages production rate. Production capacity is low in comparison to consumed energy quantity. Industrial waste plastic material type and extruder feeding method slows down the mass production. Production quality of product produced from industrial waste plastic is low because of technical inadequacy of feeding of shred flakes to the extruder.

When patents in the related art are searched, in the technical content of patent with application number of TR2006/00961 ; invention relates to prevention of flange occurring during operation of the single and double screw plastic extruder machine and to minimize return pressure, ensure low cost, high quality and long-life operation.

In conclusion, developments have been made in recycling machine and, therefore, new embodiments eliminating the above disadvantages and offering solutions to existing systems are needed.

A further purpose of the invention is to reduce screw speed and supply correct amount of shred plastics to the extruder and allow operation of extruder at right capacity and reduce energy loss and enhance product quality if the material type is film (plastic bag, packaging waste etc.).

Another purpose of the invention is to increase to proper speed for extruder screw revolving operation and allowing operation of extruder at capacity and increase granulate quality and hourly production quantity of extruder if the material type is thick rigid (crate, pallet, pipe etc.) since shredder and extruder screw speed is independently adjustable.

A further purpose of the invention is to prevent melting of waste plastic on rotor and covering rotor and shredder blades thanks to different shredder rotor and extruder screw speed and providing increase-decrease of extruder screw speed externally and use of feeding module as collection chamber at the same time.

A further purpose of the invention is to ensure stable output capacity according to type and form of post-industrial plastics to be processed.

Another purpose of the invention is to store the flakes in the storage chamber below the shredder rotor if the shredding capacity is higher than the extrusion capacity when machine is overloaded by the operator. Thanks to this automatic feeding system with storage chamber, post-industrial plastics pass the shredding part and prevent melting on the rotor. By this feeding system product quality and output capacity is increased.

Working principle of invented plastic recycling machine (100) is described as follows:

After industrial waste is shred by the shredder rotor (301 ) in the shredder module (300), it is poured into the feeding module (400) having collection chamber and feed to extruder module (200) at desired rate according to type of the shred waste plastic material in the feeding module (400) by means of single type, side by side double type or one on another double type pusher member (402) to the extruder module (200) by means of hydraulic, mechanic and automated system is provided. For instance, if the material form is film (plastic bag, packaging waste etc.)-since shredder module (300) and extruder screw (201 ) driving member is provided by independent gearbox (103) system, extruder screw (201 ) speed and speed of single type, side by side double type and one on another double type pusher member (402) located in pushing space (400.1 ) inside the feeding module (400) are reduced and correct quantity of shred waste plastic is fed to extruder module (200) and thus capacity operation of the extruder module (200) is provided. Thus, energy loss reduced, and product quality is increased.

In an another example, if the material form is thick rigid (crate, pallet, pipe etc.), when shredder module (300) shreds the industrial waste plastic called thick rigid materials, since the shredder rotor (301 ) and extruder screw (201 ) have independently adjustable speed, convenient speed for extruder screw (201 ) and speed of single type, side by side double type and one on another double type pusher member (402) located in pushing space (400.1 ) inside the feeding module (400) is increased and capacity operation of the extruder module (200) is provided. This case increases quality of granulate obtained from the extruder module (200) and hourly production quantity.
