Description

A plastic bottle cap recycling device Technical Field

[0001] This utility model belongs to the field of plastic recycling technology, and in particular relates to a plastic bottle cap recycling device. Background Technology

[0002] Plastic recycling, in short, refers to the process of transforming waste plastic products into usable resources or raw materials through a series of processing procedures. This process aims to reduce the pollution of the environment by plastic waste, while realizing the recycling of resources and promoting sustainable development. Plastic recycling mainly includes the following key steps: collection, sorting, cleaning, crushing, melting, and reprocessing. First, waste plastic products are collected and then carefully sorted to ensure that different types of plastics are properly processed. Next, these plastics are thoroughly cleaned to remove stains and impurities attached to the surface. After that, they are crushed into small pieces to facilitate subsequent melting. During the melting process, the plastic is heated to a molten state to form reprocessable plastic raw materials. Finally, these raw materials can be used to produce new plastic products or other products.

[0003] A published patent, CN119458698A, discloses a plastic product recycling device, including a feeding bin and a crushing bin, as well as clamping plates located within the feeding bin (multiple sets of clamping plates); a crushing unit located within the crushing bin, used to crush the plastic bottle body and cap separately; and a bidirectional drive unit located within the feeding bin, with clamping plates mounted on the bidirectional drive unit, which drives the two clamping plates to hold the plastic bottle and simultaneously controls the clamping plates at both ends of the bottle to rotate in opposite directions. This plastic product recycling device addresses the issue that plastic bottles are typically made of different plastic materials with varying physical and chemical properties. Mixing these materials during recycling reduces the quality of the recycled plastic. By separating the bottle body and cap, different types of plastic can be more effectively recycled and processed, thereby improving the purity of the recycled plastic. However, during the separation of the plastic bottle body and cap, residue from the plastic bottle flows onto the recycling device. This residue not only affects the subsequent processing of the cap but also damages the recycling device, impacting the recycling efficiency of the cap. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a plastic bottle cap recycling device that can clean the residue inside the plastic bottle during the recycling process, thereby enabling the plastic bottle caps to be recycled more effectively.

[0005] In view of this, the present invention provides a plastic bottle cap recycling device, characterized in that it includes a frame, on which are arranged:

[0006] The feeding box is fixedly mounted on the frame and has a feeding port.

[0007] A separation device is installed inside the feed hopper, and the separation device is used to separate the plastic bottle body and the plastic bottle cap.

[0008] A cleaning device is disposed above the separation device and is used to clean the residue on the plastic bottle.

[0009] In this technical solution, the plastic bottle includes a bottle body and a bottle cap. The plastic bottle is fed into the separation device from the feeding box. The separation device separates the bottle body and the bottle cap. During the separation process, the cleaning device cleans the stains on the bottle body and the bottle cap, so that the bottle cap can be better recycled in the subsequent recycling process, thereby improving the recycling efficiency of plastic bottle caps.

[0010] Furthermore, the separation device includes:

[0011] A compression mechanism is provided inside the feed hopper and is used to compress and separate plastic bottles.

[0012] A screening mechanism is located below the compression mechanism, and the screening component is used to screen out plastic bottle caps for recycling.

[0013] A drive assembly is fixedly mounted on the frame and is used to drive the compression mechanism to move.

[0014] In this technical solution, the drive component can be a motor to drive the compressor.

[0015] Furthermore, the compression mechanism includes: a compression roller, which is rotatably mounted on the inner wall of the feed box. The outer surface of the compression roller is provided with a plurality of elongated rectangular roller protrusions at equal intervals. The height of the roller protrusions is less than the diameter of the bottle body, and the axial distance between a pair of compression rollers is greater than the diameter of the compression roller plus the height of the two roller protrusions.

[0016] In this technical solution, the plastic bottle enters the separation device. When a pair of compression rollers rotate, the bottle is conveyed between the compression rollers by the roller protrusions, so that the plastic bottle is compressed by the compression rollers and roller protrusions. Since the plastic bottle is sealed and contains air, under the action of pressure, the bottle body and bottle cap will separate during the compression process, thereby achieving the purpose of quickly separating the bottle body and bottle cap, which is convenient for operation.

[0017] Furthermore, a positioning seat is fixedly provided on the roller protrusion, and a through hole is provided through the positioning seat. Multiple through holes are arranged axially on the positioning seat. A compression pin is provided inside the through hole. The compression pin includes a spring and a needle-shaped compression block fixedly provided at one end of the spring. The height of the compression block is greater than the height of the positioning seat. The compression pins on one compression roller and the compression pins on another compression roller are arranged alternately in the length direction of the compression roller.

[0018] In this technical solution, when the plastic bottle is compressed between a pair of compression rollers, the compression block on the compression pin will pierce into the plastic bottle under the action of the spring force, so that the plastic bottle body is penetrated, thereby completely expelling the residue inside the plastic bottle, making it easier to clean the plastic bottle.

[0019] Furthermore, the cleaning device is fixedly installed on the side wall of the feed box, and the cleaning device includes:

[0020] A water tank, which is fixedly installed on the outside of the feed box, and contains clean water;

[0021] A water pump, wherein the water pump is mounted on a water tank and one end of the water pump is connected to the water tank;

[0022] The nozzle is located on the inner wall of the feed box, and a water pipe is provided at one end of the nozzle. One end of the water pipe is connected to a water pump.

[0023] In this technical solution, during the separation process, the residue from the plastic bottle will flow out, contaminating the inner surface of the feed box, a pair of compression rollers, the plastic bottle body, and the bottle cap. The water pump supplies clean water from the water tank to the nozzle, and the nozzle sprays clean water to clean the inner surface of the feed box, the pair of compression rollers, the plastic bottle body, and the bottle. At the same time, it can also remove the mud and sand attached to the surface of the plastic bottle. After the separation is completed, the entire separation device can also be cleaned to prevent damage to the device.

[0024] Furthermore, the screening mechanism includes a primary screening component and a secondary screening component, wherein the primary screening component is used to screen out plastic bottle bodies and the secondary screening component is used to screen out plastic bottle caps.

[0025] Furthermore, a screening box is fixedly installed below the feed box, and the primary screening component is installed inside the screening box. The primary screening component includes:

[0026] The main screen is fixedly mounted on the side wall of the feed box at both ends. The main screen is semi-arc-shaped and its outer diameter is smaller than the width of the feed box.

[0027] Multiple mesh openings are arranged on the main screen, the diameter of which is larger than the diameter of the plastic bottle cap and smaller than the diameter of the plastic bottle body.

[0028] In this technical solution, after the compression mechanism finishes separating, the plastic bottle body, bottle cap, and wastewater enter the screening box. The plastic bottle body and bottle cap are screened on the main screen, while the bottle cap and wastewater enter the secondary screening component through the mesh, and the plastic bottle body is left on the main screen, effectively and conveniently separating the bottle body and bottle cap.

[0029] Furthermore, a power source is fixedly installed on the screen, and a stirring shaft is installed above the main screen. The stirring shaft is installed through the screen box, and a spiral shaft protrusion is provided on the outer surface of the stirring shaft. The maximum diameter of the stirring shaft is adapted to the inner diameter of the main screen, and the output end of the power source is connected to one end of the stirring shaft.

[0030] In this technical solution, the power source can be an electric motor that drives the stirring shaft to rotate. Under the rotation and stirring of the shaft protrusion, the bottle body and the bottle cap can be better separated, so that the bottle cap can be effectively discharged from the mesh, and the bottle cap can be effectively sorted from the bottle body.

[0031] Furthermore, the secondary filtering component is positioned below the primary filtering component, and the secondary filtering component includes:

[0032] A secondary screen is located below the main screen. Both ends of the secondary screen are fixed to the side wall of the screening box. The secondary screen is arc-shaped, and its outer diameter is adapted to the internal width of the feed box. One side of the secondary screen is fixedly connected to the side wall of the screening box.

[0033] A sieve screen with multiple sieve holes arranged on a secondary sieve screen, the diameter of which is smaller than the diameter of the bottle cap;

[0034] Side plate, the side plate is fixedly installed on one side of the auxiliary screen, the side plate is inclined downward along the width direction of the screening box.

[0035] In this technical solution, bottle caps and wastewater pass through a secondary screen. The wastewater is screened out through the screen holes and enters the bottom of the screening box, while the bottle caps remain on the secondary screen. The bottle caps are then transported to a recycling box outside the screening box via an inclined side plate, thus completing the separation and recycling of the bottle caps.

[0036] Furthermore, both ends of the secondary screen are inclined towards the middle along the length of the screening box.

[0037] In this technical solution, the tilting of both ends of the secondary screen allows the bottle caps to stay on the secondary screen for a longer time, better separating the bottle caps from the sewage, while also collecting all the bottle caps in the middle, making it easier to recycle the bottle caps.

[0038] The beneficial effects of this utility model are:

The separation device separates the bottle body and the bottle cap. During the separation process, the cleaning device cleans the stains on the bottle body and the bottle cap, so that the bottle cap can be better recycled in the subsequent recycling process, thereby improving the recycling efficiency of plastic bottle caps.
