[0027] Example:

[0028] like Figure 1 and Figure 2 As shown, the present invention proposes a production equipment for waste plastic recycling and granulation, comprising: a sealing cover 1 for sealing and conveying plastic bottles, the interior of the sealing cover 1 being hollow, and an outlet 2 for discharging plastic bottles at one end of the sealing cover 1 to facilitate the discharge of collected plastic bottles; a feed hopper 3 for placing plastic bottles through the upper surface of the sealing cover 1 to facilitate the addition of collected plastic bottles into the interior of the sealing cover 1; a conveying assembly 4 for conveying plastic bottles inside the sealing cover 1 to facilitate the automatic conveying of plastic bottles placed inside the sealing cover 1; and a cutting assembly 5 fixedly disposed on the upper surface of the sealing cover 1 for cutting the plastic bottles conveyed by the conveying assembly 4, capable of cutting and discharging the remaining liquid inside the conveyed plastic bottles.

[0029] Furthermore, the conveying assembly 4 includes a set of rotating rods 41 rotatably disposed inside the sealing cover 1. A conveyor wheel 42 is fixedly sleeved on the outer wall of the rotating rod 41. A conveyor belt 43 is disposed between the conveyor wheels 42. The conveyor belt 43 is relatively thick to facilitate stable conveying of plastic bottles. A groove 44 is provided on the outer wall of the conveyor belt 43. Multiple partitions 45 for separation are fixedly disposed inside the groove 44 to convey plastic bottles individually. One end of the rotating rod 41 passes through the sealing cover 1 and extends to be connected to a first drive wheel 46 to facilitate driving the conveyor belt 43 to rotate.

[0030] like Figure 2 and Figure 3As shown, the cutting assembly 5 includes a set of support blocks 501 fixedly mounted on the upper surface of the sealing cover 1. The support blocks 501 are symmetrically arranged, and mounting grooves 502 are respectively opened on the opposite surfaces of the support blocks 501. A guide rod 503 is fixedly mounted inside the mounting groove 502. A guide sleeve block 504 is movably sleeved on the outer wall of the guide rod 503, which can limit the guide sleeve block 504 and ensure its stable vertical up and down movement. A connecting block 505 is fixedly mounted between the guide sleeve blocks 504. A cutter 506 is fixedly mounted on the bottom surface of the connecting block 505. The cutter 506 movably passes through the sealing cover 1, which facilitates the vertical up and down movement of the cutter 506 at the bottom of the connecting block 505, thereby cutting the conveyed plastic bottle and draining the internal liquid. A spring 507 is fitted onto the outer wall of the plastic bottle. One end of the spring 507 is fixedly connected to the support block 501, and the other end of the spring 507 is fixedly connected to the guide block 504. This allows the cutter 506 to be reset and cyclically cut. A motor 508 is fixedly installed on one side of the support block 501. The output end of the motor 508 passes through the support block 501 and extends to connect to a second transmission wheel 509. A transmission belt 510 is provided between the second transmission wheel 509 and the first transmission wheel 46, which can simultaneously drive the conveyor belt 43 to rotate, thereby reducing energy consumption and production costs. A cam 511 is fixedly fitted onto the output end of the motor 508. The cam 511 is located between the support blocks 501, which facilitates pushing the cutter 506 up and down to cut the plastic bottle.

[0031] like Figure 1 and Figure 2 As shown, a collection box 6 is provided at one end of the sealing cover 1 to facilitate the collection of plastic bottles discharged from the outlet 2. A filter plate 7 is fixedly installed inside the collection box 6 to separate the plastic bottle from the internal liquid.

[0032] Secondly, a bracket 8 is fixedly installed at one end of the sealing cover 1, and a rinsing nozzle 9 for cleaning the conveyor belt 43 is fixedly installed on the bracket 8, which can keep the conveyor belt 43 clean and prevent odors from appearing.

[0033] Furthermore, the groove 44 is arc-shaped, which can match the shape of the plastic bottle, thus ensuring stable cutting of the plastic bottle.

[0034] In addition, an impact block 10 is fixedly provided on the upper surface of the connecting block 505 to prevent the cam 511 from directly impacting the connecting block 505, thereby improving its service life.

[0035] The working principle of this embodiment is as follows: First, waste plastic bottles are placed into the sealed cover 1 through the feed hopper 3. The feed hopper 3 penetrates the upper surface of the sealed cover 1, providing a channel for the plastic bottles to enter the equipment. Inside the sealed cover 1, the motor 508 drives the second transmission wheel 509 to rotate. The second transmission wheel 509 drives the first transmission wheel 46 to rotate through the transmission belt 510. The first transmission wheel 46 drives the conveyor wheel 42, which is fixedly sleeved on the rotating rod 41, to rotate, thereby driving the conveyor belt 43 to operate. The grooves 44 opened on the conveyor belt 43 and the internally fixed partitions 45 can separate and position the plastic bottles, ensuring that the plastic bottles are conveyed stably one by one.

[0036] When the plastic bottle is conveyed to the area below the cutting assembly 5, the output of the motor 508 drives the cam 511 to rotate. Since the cam 511 is located between the support blocks 501, as the cam 511 rotates, it continuously presses against the impact block 10 on the upper surface of the connecting block 505, causing the connecting block 505 and the cutter 506 fixed to its bottom surface to move up and down. When the cutter 506 moves downward, it cuts the plastic bottle on the lower conveyor belt 43, causing the remaining beverage inside the bottle to flow out automatically. When the cutter 506 completes the cutting action and lifts upward, the guide sleeve 504 drives the connecting block 505 to reset, ready for the next cut, due to the elastic action of the spring 507 sleeved on the guide rod 503.

[0037] The cut plastic bottle and the flowing liquid are discharged from the outlet 2 at one end of the sealing cover 1. A collection box 6 is provided below the outlet 2. The filter plate 7 fixed inside the collection box 6 can perform preliminary separation of liquid and solid, which is convenient for subsequent separate processing.

[0038] A rinsing nozzle 9 is fixedly installed on the bracket 8 at one end of the sealing cover 1. Its function is to clean the conveyor wheel 42, ensure that the conveyor wheel 42 remains clean during continuous operation, and ensure the normal operation of the conveying work.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
