Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, in particular to a device for recycling waste plastics. Background Art

[0002] White pollution is a vivid name for the phenomenon of non-degradable plastic waste polluting the environment. The main sources of white pollution are food packaging, foam plastic filling packaging, fast food boxes, agricultural mulch, etc. We are creating white pollution every day. Because plastic products are difficult to decompose, abandoned plastic products (especially various plastic bags) bring great pollution to our living environment, causing our originally clean and tidy living environment to be eroded by white.

[0003] Existing waste plastic processing equipment usually separates different links for independent processing, such as extrusion, heating, stirring, conveying, etc., and requires independent power systems and temperature control systems. This multi-system independently driven design brings about problems such as complex equipment structure, difficult maintenance and excessive energy consumption. Moreover, existing equipment usually uses a uniform temperature for heating plastics. This inaccurate temperature control method cannot adapt to the melting points of different plastics, resulting in unstable plastic processing effects and easily causing quality problems. For example, low-melting-point plastics may decompose at too high a temperature, while high-melting-point plastics may not be fully melted, affecting the subsequent processing process. At the same time, existing plastic recycling equipment has not effectively solved the problems encountered in household recycling. The waste plastics generated by households are usually of different shapes, large in size, low in density, easy to float, and inconvenient to store and transport. The recycling methods of existing equipment usually rely on manual sorting and complex preliminary processing, which increases the difficulty of operation and reduces the recycling efficiency. Plastic recycling units often find it difficult to directly use these waste plastics, and the recycling value is low, further exacerbating the waste of resources. Summary of the invention

The knob 1207 adjusts the tension of the pull rope 1206 by rotating, thereby driving the limit block 1203 to slide in the limit slot 1201, and then adjusting the fixation and release of the collection box 1108. The rotation of the knob 1207 effectively controls the connection state between the card block 1204 and the card slot 1205. When the collection box 1108 needs to be replaced or cleaned, the operation can be easily completed by rotating the knob 1207.

[0039] Working principle: First, household waste plastics enter the interior of the device through the feed port 8. After entering the mounting frame 3, the waste plastics are guided to the extrusion assembly 4, which includes an extrusion roller 1 401 and an extrusion roller 2 402, which are driven by a driving gear 705 and a driven gear 706, respectively. The extrusion roller 1 401 is fixedly connected to the right side of the driving gear 705, and the extrusion roller 2 402 is connected to the extrusion roller 1 401 through the driven gear 706. When the motor 702 is started, the driving gear 705 drives the extrusion roller 1 401 to rotate, and the driven gear 706 drives the extrusion roller 2 402 to rotate. The waste plastics are compressed between the two extrusion rollers and undergo preliminary plastic treatment to reduce the volume and increase fluidity.

[0040] Secondly, the waste plastic after extrusion is pushed to the heating area of ​​the mounting frame 3. At this time, the waste plastic enters the heating system composed of multiple heating rods 13. The heating rods 13 are located inside the mounting frame 3 and distributed on the conveying path of the plastic. Through the heating effect of the heating rods 13, the extruded plastic is melted to the required processing temperature, and the motor 702 drives the pulley 1 704 to rotate, so that the pulley 2 707 drives the transmission rod 708 to rotate, so that the bevel gear 1 710 rotates and drives the bevel gear 2 711 to rotate, so that the rotating rod 501 rotates and drives the stirring rod 502 to evenly add gravure to the heated plastic, and at the same time, the scraper 503 is used to reduce the adhesion of the plastic to the inner wall. The role of the heating process is to ensure that the plastic can smoothly enter the mold 1101 for molding after reaching an appropriate molten state.

[0041] Then, the heated plastic is pushed into the mold 1101 through the conveying assembly 6. The conveying assembly 6 includes a conveying chamber 601 and a screw 602. The screw 602 rotates by connecting with the base 1 to effectively convey the molten plastic to the opening of the mold 1101. This process ensures that the molten plastic can enter the mold 1101 evenly and smoothly for precise shaping.

[0042] Next, the plastic enters the mold 1101 and begins to be molded. The front side of the mold 1101 is controlled by the baffle 1102, and the opening and closing of the baffle 1102 is controlled by the electric push rod 1103. The output end of the electric push rod 1103 is connected to the slider 1104, and the slider 1104 slides in the slide groove 1105 to ensure that the baffle 1102 can be accurately controlled. After molding, the electric push rod 2 1106 is started, and the finished plastic in the mold 1101 is pushed out through multiple ejectors 1107, and the plastic is pushed to the collection box 1108 below.

[0043] Finally, the collection box 1108 is located below the base 1, and is used to receive the finished plastic product pushed out from the mold 1101. The pull rope 1206 is adjusted by the knob 1207 to drive the limit block 1203 to slide in the limit slot 1201, so that the card block 1204 can dock with the card slot 1205 in the collection box 1108, thereby firmly fixing the collection box 1108 to prevent the finished plastic product from falling. In this way, the waste plastics generated by the household are converted into plastic raw materials with regular volume and easy to transport. The recycling agency will collect them and transport them to the plastic product factory for secondary processing to achieve the reuse of plastics.
