[0002] In modern daily life, countless plastic bottles are produced and consumed every day, such as bottles of Coke, Sprite, mineral water, and Orange Juice, which are made of PET resin (polyethylene terephthalate), a type of plastic, which is a recyclable resource. With the increasing awareness of environmental protection, more and more countries and regions have begun to pay attention to the recycling of such plastic bottles. During the recycling process of waste plastic bottles, some waste plastic bottles will inevitably have residual liquid, and may also be contaminated with mud, oil, mud, dirt, etc. When recycling and reshaping, it is necessary to ensure the cleanliness of the waste plastic bottles to ensure the quality of the reshaping. For this reason, these waste plastic bottles need to be cleaned first.

[0003] When cleaning plastic bottles, since they are semi-closed and have a small bottle mouth, there are dead corners on the inner wall of the plastic bottles. The cleaning equipment cannot effectively clean the inner wall of the plastic bottles, resulting in poor cleaning effect. A lot of dirt will remain inside the plastic bottles, resulting in the recycling process of plastic bottles being unable to ensure quality, resulting in a large number of defective products and affecting the recycling rate.

The end of the connecting rod away from the sliding ring is connected to the middle of the top of the gate plate.

[0014] A method for recycling and cleaning waste plastic bottles comprises the following steps:

[0015] S1: First, start the servo motor to push the waste plastic bottles into the bottle inlet pipe. The servo motor drives the rotating shaft 1, so that the cutting blades 1 and 2 rotate to cut the waste plastic bottles into pieces and enter the washing box.

[0016] S2: Start the high-pressure water pump to draw water from the water tank and input it into the water jet. The water jet cuts the waste plastic bottles, and the dirt inside the waste plastic bottles is separated under the action of high-pressure water. When the waste plastic bottles are cut into plastic pieces of a certain size, they will fall from the screening plate into the lower half of the washing box;

[0017] S3: The loading rod rotates along the rotating shaft. When the plastic block falls, the cleaning rod collides and rubs against the plastic block, and the cleaning bristles scrub the surface of the plastic block. The cleaning rod rotates around the loading rod as the cleaning process progresses, allowing the cleaning bristles to scrub at wider angles and ranges. After cleaning is complete, the plastic block sinks to the bottom of the water tank.

[0018] S4: When the servo motor is started, the active pulley rotates, driving the power belt, which rotates the driven pulley, drives the drain shaft, rotates the second rotating shaft, and drives the vortex drain rail to rotate, sucking the water flow from the bottom of the water tank, so that the plastic blocks sunk to the bottom of the water tank enter the drain tank with the water flow, and after being drained by the drain tank, they rise with the vortex drain rail and finally slide out of the discharge chute;

[0019] S5: When the waste plastic bottles are cut, the brand labels on the outer wall of the plastic bottles will also be shredded. When the broken brand labels flow out of the cleaning box with the water, the brand labels will float up and float into the storage box because their density is less than that of water. When the storage box collects a certain amount of brand labels, pull out the limit rod, move the sliding ring, close the gate, pull the pull rod, remove and clean the storage box.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting the cutting knife 1 and the cutting knife 2, the waste plastic bottles are decomposed into multiple independent individuals, making it convenient to clean the inner wall of the plastic bottle, ensuring that all parts of the plastic bottle can be cleaned, improving the cleaning effect, and ensuring the recycling quality.

[0022] 2. By setting up a water jet, the cutting efficiency of waste plastic bottles is increased, and under the action of high-pressure water flowing out of the water jet, the dirt attached to the waste plastic bottles will be separated from the plastic bottles, further improving the cleaning effect.

[0023] 3. By setting up a vortex drain rail, the plastic block rises from the bottom of the water tank to the top of the drain tank, allowing the plastic block to drain, reducing the moisture on the surface of the plastic block and reducing the probability of the plastic block surface being contaminated with dust and impurities due to excessive moisture.

Example

[0037] A waste plastic bottle recycling and cleaning device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1 and Figure 7 As shown,

[0038] A storage box 22 is clamped on the front inner wall and the rear inner wall of the water storage tank 1 near the middle, and the storage box 22 is located in the gap between the drain box 4 and the cleaning box 13.

[0039] A method for recycling and cleaning waste plastic bottles comprises the following steps:

[0040] S1: First, the servo motor 11 is started to push the waste plastic bottles into the bottle inlet pipe 14. The servo motor 11 drives the rotating shaft 1 20 to rotate the cutting blade 1 26 and the cutting blade 2 30 to cut the waste plastic bottles into pieces and enter the washing box 13;

[0041] S2: Start the high-pressure water pump 17 to draw water from the water tank 1 and input it into the water jet 2. The water jet 2 cuts the waste plastic bottles, and the dirt inside the waste plastic bottles is separated under the action of the high-pressure water force. When the waste plastic bottles are cut into plastic pieces of a certain size, they will fall from the screening plate 21 into the lower half of the washing box 13;

[0042] S3: The loading rod 19 rotates along the rotating shaft 20.

[0043] S4: When the servo motor 11 is started, the driving pulley 27 rotates, driving the power belt 10, the driven pulley 9 rotates, the drain shaft 8, the rotating shaft 23 rotates, and the vortex drain rail 31 rotates, sucking the water flow from the bottom of the water tank 1, so that the plastic blocks sunk to the bottom of the water tank 1 enter the drain tank 4 with the water flow, and after being drained by the drain tank 4, they rise with the vortex drain rail 31 and finally slide out of the discharge chute 6;

[0044] S5: When the waste plastic bottles are cut, the brand labels on the outer walls of the plastic bottles will also be shredded. When the broken brand labels flow out of the cleaning box 13 with the water flow, the brand labels will float up because the density of the brand labels is less than the density of water and drift into the storage box 22. When the storage box 22 collects a certain amount of brand labels, pull out the limit rod 39, move the sliding ring 38, close the gate 3, pull the pull rod 41, and remove and clean the storage box 22.

After the cleaning is completed, the plastic block sinks to the bottom of the water storage tank (1); S4: When the servo motor (11) is started, the driving pulley (27) rotates, driving the power belt (10), causing the driven pulley (9) to rotate, driving the drain shaft (8), causing the second rotating shaft (23) to rotate, driving the vortex drain rail (31) to rotate, absorbing the water flow at the bottom of the water storage tank (1), causing the plastic blocks sunk to the bottom of the water storage tank (1) to enter the drain tank (4) along with the water flow, and after being drained by the drain tank (4), they rise along the vortex drain rail (31) and finally slide out from the discharge trough (6); S5: When the waste plastic bottles are cut, the brand labels on the outer walls of the plastic bottles are also cut into pieces. When the broken brand labels flow out of the cleaning box (13) with the water flow, the brand labels float up because the density of the brand labels is less than the density of water, and float into the storage box (22). When the storage box (22) collects a certain amount of brand labels, the limit rod (39) is pulled out, the sliding ring (38) is moved, the gate (3) is closed, and the pull rod (41) is pulled to remove and clean the storage box (22).
