Description

Technical Field

[0001] This invention relates to the field of waste plastic recycling and processing cabinet technology, and in particular to a plastic combined crusher. Background Technology

[0002] With the increasing consumption of plastic bottles, the recycling and processing of waste plastic bottles has become a crucial aspect of resource recycling and environmental protection. Currently, plastic bottle recycling and processing equipment on the market is typically a fixed, large-scale production line, requiring the centralized transportation of collected plastic bottles to a processing plant for processes such as label removal, sorting, crushing, and separation. This centralized processing model has the following problems: First, transportation costs are high, and the collection range is limited by transportation economics; second, the equipment occupies a large area, resulting in high investment costs, making it unsuitable for decentralized, small-batch on-site recycling needs; third, it has poor adaptability to remote areas or scattered collection points, making it difficult to achieve an efficient "on-site recycling, on-site processing" operation mode. Summary of the Invention

[0003] In view of this, in order to solve the problems existing in the technical background, the present invention proposes a plastic combined crushing machine that is highly integrated, mobile, and capable of completing the entire process of plastic bottle crushing and separation on-site. Specifically, it includes the following:

[0004] A plastic combined crusher, characterized in that it comprises a feeding mechanism, a label removal mechanism, a sorting and detection mechanism, a crushing mechanism, and a rinsing and separating mechanism connected in sequence. The feeding mechanism is used to lift and convey bottles, the label removal mechanism removes bottle labels, the crushing mechanism crushes the bottles into fragments, and the rinsing and separating mechanism uses the buoyancy of water to separate bottle fragments from bottle cap fragments. The label removal mechanism, crushing mechanism, rinsing and separating mechanism, and feeding mechanism are integrated on a mobile vehicle platform.

[0005] Furthermore, the feeding mechanism includes an inclined conveyor belt for conveying bottles to the label removal mechanism.

[0006] Furthermore, the label-removing mechanism includes at least one rotating blade, a fixed blade, a high-pressure suction fan, and a suction port. The fixed blade is located below the rotating blade without contact, and the rotating blade and the fixed blade cooperate to tear and shred the label. A suction port is formed in the gap between the fixed blades, and the suction port is connected to the high-pressure suction fan.

[0007] Furthermore, the feeding mechanism also includes a lifting baffle, an optical camera, and a first high-pressure jet separator. The lifting baffles are evenly distributed on the conveyor belt, and the optical camera is located above the non-contact section of the conveyor belt. The first high-pressure jet separator is located at the connection between the feeding mechanism and the bidding structure.

[0008] Furthermore, the sorting and inspection mechanism includes a first conveyor belt, a second conveyor belt, a second high-pressure jet separator, and an electronic camera. The mat camera is located between the label removal mechanism and the sorting and inspection mechanism. The second high-pressure jet separator is located above the first conveyor belt without contact. The first and second conveyor belts are located on the same plane.

[0009] Furthermore, the crushing mechanism includes a screen, blades, and a first spiral propeller, with the screen located below the blades and the first spiral propeller located at one end of the blades.

[0010] Furthermore, the rinsing and separation mechanism includes a rinsing tank, a second spiral propeller, and a discharge port. The rinsing tank is used to separate bottle body fragments and bottle cap fragments by the buoyancy of water. The bottom of the rinsing tank and one end of the rinsing tank are provided with a second spiral propeller. The discharge port is provided above the second spiral propeller to push the bottle body fragments that sink to the bottom to the discharge port to complete the discharge.

[0011] The above technical solution has the following beneficial effects:

[0012] This invention integrates multiple processes such as feeding, label removal, sorting, crushing, and rinsing separation onto a vehicle-mounted platform, enabling rapid deployment and relocation to adapt to the recycling needs of different regions, significantly expanding the operating radius and reducing transportation costs. Through the combination of an optical camera and a high-pressure jet separator, it achieves automatic bottle sorting and secondary rejection of bottles with incomplete label removal; utilizing the principle of water buoyancy, it achieves efficient physical separation of the bottle body and cap, improving the purity of the raw materials. The various mechanisms are tightly integrated, the process is seamless, reducing manual intervention and operational difficulty, making it suitable for efficient recycling operations within limited spaces.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] See Figure 1 The plastic combined crusher shown includes a feeding mechanism 1, a label removal mechanism 2, a sorting and detection mechanism 3, a crushing mechanism 4, and a rinsing and separation mechanism 5 connected in sequence. All mechanisms are integrated and installed on a mobile vehicle platform.

[0022] The feeding mechanism 1 includes an inclined conveyor belt 11 with lifting baffles 12 evenly spaced on it to support the plastic bottles during lifting and prevent them from slipping. An optical camera 13 is mounted above the conveyor belt 11 to identify the bottle's color, type, or location. At the end of the conveyor belt 11, where it connects with the label removal mechanism 2, a first high-pressure jet separator 14 is located. During operation, waste plastic bottles are lifted onto the conveyor belt 11. The optical camera 13 captures bottle information and generates an electronic signal, controlling the first high-pressure jet separator 14 to blow specific bottles away from the main line and into a bypass channel for initial sorting. Qualified bottles then continue into the label removal mechanism 2.

[0023] The electronic camera 34 of the sorting and detection mechanism 3 is used to capture bottles that are not properly labeled and send an electronic signal to the second high-pressure jet separator 33, so that the bottles are blown away by high-pressure gas and enter the separation channel when they enter between the first conveyor belt 31 and the second conveyor belt 32. The speed of the conveyor belt 11 of the feeding mechanism 1 is controlled by a frequency converter. The rinsing and separation mechanism 5 has a box structure in the rinsing tank 51, in which bottle fragments sink as bottom material and bottle cap fragments float as floating material, thus achieving separation of the two.

[0024] The label removal mechanism 2 includes a rotating blade 21, a fixed blade 22, a high-pressure suction fan 23, and a suction port 24 located in the gap between the fixed blade 22. The fixed blade 22 is positioned below the rotating blade 21, maintaining a non-contact gap between them. During operation, the bottle enters between the rotating blade 21 and the fixed blade 22, and the bottle label is peeled off under the high-speed rotating tearing action. Simultaneously, the high-pressure suction fan 23 generates negative pressure through the suction port 24, sucking in the torn label fragments and collecting them through a pipe, achieving effective separation of the label from the bottle. The label-removed bottles then enter the subsequent sorting and inspection mechanism 3.

[0025] The sorting and inspection mechanism 3 includes a first conveyor belt 31 and a second conveyor belt 32 located on the same horizontal plane. An electronic camera 34 is installed at the exit of the label removal mechanism 2. The electronic camera 34 is used to detect the label residue on the bottle after label removal. When the bottle moves from the first conveyor belt 31 to between the first and second conveyor belts 32, if the electronic camera 34 detects that a bottle has not been properly labeled, it sends a signal to the second high-pressure jet separator 33. The high-pressure airflow blows the bottle away from the main conveyor line and into the return channel to return to the label removal mechanism 2 for reprocessing. Bottles that have passed the label removal smoothly enter the second conveyor belt 32 and are transported to the crushing mechanism 4.

[0026] The crushing mechanism 4 includes blades 42, a screen 41 located below the blades 42, and a first screw propeller 43 located at the feed end of the blades 42. Clean bottles, after label removal, are pushed into the crushing chamber by the first screw propeller 43 and crushed under the high-speed shearing and impact of the blades 42. The fragments are screened by the screen 41; fragments that meet the size requirements fall into the rinsing and separation mechanism 5 below, while larger fragments continue to be crushed within the chamber.

[0027] The rinsing and separation mechanism 5 includes a water-filled rinsing tank 51, a second spiral propeller 52 installed at the bottom and inclined end face of the rinsing tank 51, and a discharge port 53 located above the second spiral propeller 52. The pulverized mixed fragments enter the rinsing tank 51. Because the bottle body fragments are denser than water, they sink to the bottom, becoming sediment, while the bottle cap fragments are less dense than water and float to the top. The second spiral propeller 52 pushes the bottle body fragments that have sunk to the bottom of the tank towards the discharge port 53, ultimately completing the recycling process by filling the bag. The floating bottle cap fragments can be collected separately. This process utilizes the buoyancy of water to achieve efficient physical separation of the bottle body and bottle cap, improving the purity of the recycled material.

[0028] Example 2, based on Example 1, in this example, after label removal, the bottles enter the sorting and inspection mechanism 3, where an electronic camera 34 captures real-time images of the bottle surface. If label residue is detected, the bottle's position information is immediately recorded. When the bottle travels with the conveyor belt to the gap between the first conveyor belt 31 and the second conveyor belt 32, the control unit precisely triggers the corresponding second high-pressure jet separator 33 based on the received position signal. A high-speed airflow is instantly ejected, blowing the bottles with incomplete label removal laterally away from the main conveyor line, causing them to fall into the side return channel. The rejected bottles are then returned to the label removal mechanism 2 for reprocessing, while the qualified bottles smoothly transition to the second conveyor belt 32 and continue to be conveyed to the crushing mechanism 4. This process achieves online automatic verification and real-time sorting of label removal quality, ensuring the purity of the subsequent crushed raw materials.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention.

All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the invention is defined by the appended claims and their equivalents.
