Description

Technical Field

[0001] The invention belongs to the technical field of plastic waste recycling, and in particular relates to an environmentally friendly plastic recycling device. Background Art

[0002] Plastic is a high molecular compound, composed of polymers, which has plasticity, that is, it can be molded into various shapes under certain conditions and can maintain these shapes after cooling. The processing technology of plastic bottles mainly includes the following steps: Injection molding: This is the first step in the manufacture of plastic bottles. Plastic particles are plasticized in the barrel of the injection molding machine. The plastic is melted by heating and the shearing action of the screw, and then injected into a multi-cavity mold to form a long and thin tube, called par isons. Reheat and blow molding: In the reheat and blow molding machine (RBM) manufacturing process, the injection molded tube is loaded into the feeder and fed into the blow molding machine through the descrambler. After entering the mold after being heated by the quartz heater, a thin steel rod (mandrel) slides into the semi-finished product of the neck. The semi-finished product is filled with highly compressed air and begins to stretch and blow mold to form the bottle shape. Cooling and shaping: The newly molded plastic bottle needs to be cooled quickly in order to be properly shaped. There are two cooling methods: direct and indirect. Pressurized air or carbon dioxide can be used directly, or water can be passed through the pipe around the mold to cool indirectly. Separation and trimming: Once the bottles have cooled and solidified, they can be removed from the mold. If they are produced continuously, they need to be separated by trimming the plastic between them.

[0003] Plastic crushing is an important step in the process of plastic recycling and reuse. Plastic bottles will be discarded after the beverage is drunk. Plastic is very harmful to the environment, so plastic bottles need to be recycled. However, in the current recycling process of plastic bottles, there are problems such as easy jamming of the crushing of plastic bottles and poor crushing effect.

One end of the water supply pipe 653 close to the U-shaped tube 643 is rotatably connected to the end of the rotating tube 641 by a sleeve connection. This design is to facilitate the flipping of the spray component 64, and at the same time, it can also maintain the connection state between the spray component 64 and the water supply component 65. The end of the water supply pipe 653 away from the U-shaped tube 643 is connected to an external water pipe.

[0035] In this embodiment, water enters through the water supply pipe 653, then enters the rotating pipe 641, and then enters the U-shaped tube 643 and finally sprayed out through the three-sided spray heads 644, thereby achieving the purpose of cleaning the three sides of the inner wall of the pipetting channel 61.

[0036] In a further embodiment, referring to Figure 6A rotating member 66 is also installed on the side of the side mounting block 63. The rotating member 66 includes an electric cylinder 661 and a rotating gear 663. The output end of the electric cylinder 661 is connected to a rack plate 662.
