Description

Surplus waste recycling device for plastic production

Technical Field

The invention relates to the technical field of plastic recycling, in particular to a plastic production redundant waste recycling device.

Background

When the mould is used for manufacturing plastic products, after the plastic products are molded, part burrs are reserved at the edge positions, plastic heads connected with the mould are reserved at the feeding holes of the mould, plastic wastes such as burrs and plastic heads are all required to be cut off, and the plastic wastes can be recycled for preventing waste.

At present, in order to save energy, the plastic waste is generally collected to a certain amount and then is subjected to centralized treatment, dust is accumulated together in the collecting process, and oil stains possibly adhere to plastic products in the production process, the oil stains, the dust and the plastic waste are recycled together in the recycling process, the dust and the recycled plastic are processed together, and the defect quality problem of the recycled plastic is possibly caused, so that the plastic waste is required to be sent into a cleaning device for cleaning so as to remove the oil stains and the dust on the surface of the plastic waste, and the quality of the plastic products after the reprocessing is ensured.

In the cleaning step, the existing methods are mainly divided into two types, namely, the first type of methods is to uniformly lay plastic waste on a net-type conveying belt and strongly wash the plastic waste through a high-pressure water gun, however, the method has a remarkable disadvantage that the plastic waste on the conveying belt is often stacked together, so that the high-pressure water gun is difficult to comprehensively and thoroughly wash each piece of plastic, and dirt still remains on part of the pieces.

Another method is to put the plastic waste into a bucket filled with cleaning liquid and stir and clean the fragments by a motor driving stirring rod, and although the method can make the plastic waste fully contact with the cleaning liquid, the same problem is that as part of the plastic waste floats on the water surface, the intractable stains attached to the fragments are difficult to effectively clean by means of stirring, so that the cleaning effect is poor.

Both methods have the characteristics, but have the problem of incomplete cleaning to different degrees, and the reprocessing quality and the utilization rate of plastic waste are affected.

Therefore, there is a need to provide a new solution to overcome the above-mentioned drawbacks.

When the three connecting plates 342 are driven by the third power source 344 to move away from each other, the connecting plates 342 drive the adjacent movable rods 353 to move, the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinders 351, so that the gas in the fixed cylinders 351 can be extruded and conveyed into the gas collecting pipes 37 through the gas guide pipes 36 and sprayed out through the gas spraying heads 38, and the gas is sprayed at the bottoms of the inclined plates 325, so that the through holes on the inclined plates 325 can be cleaned, and the problem that dust blocks the through holes to influence the air flow in the treatment box 31 when the crushing starts is avoided.

When the third power source 344 drives the two connecting plates 342 to approach each other, the connecting plates 342 drive the adjacent movable rods 353 to move, and the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinders 351, so that gas can be sucked into the fixed cylinders 351, and the subsequent use is ready.

Meanwhile, the reciprocating movement of the rack 3572 can drive the connecting gear 39 to reciprocally rotate, so as to drive the gas collecting tube 37 to reciprocally swing, thereby expanding the gas spraying range of the gas spraying head 38, further comprehensively cleaning the through holes on the inclined plate 325 and improving the cleaning effect.
