[0046] The cleaning device 11 includes a centrifugal motor, a cleaning rod 14, a chassis 15 and a filter screen 16. The centrifugal motor includes a centrifugal column 13, a motor 1703, a transmission gear 1702 and a driven gear 1701. The centrifugal column 13 is connected to the driven gear 1701, the motor 1703 is connected to the transmission gear 1702, the transmission gear 1702 is meshed with the driven gear 1701, the bottom of the cleaning rod 14 and the bottom of the centrifugal column 13 are both connected to the chassis 15, and the filter screen 16 is installed on the inner wall of the machine body and above the chassis 15.

[0047] Add bottle flakes raw materials into the cleaning device 1, add water into the cleaning device 11 through the water pipe 12 to submerge the upper end of the "S"-shaped track 8, and then move the driving shaft 3 to the first corner of the "S"-shaped track 8 through the active compressor 5, and the driven shaft 4 is at the end point of the "S"-shaped track 8.

[0048] When cleaning starts, the motor 1703 starts, and the motor 1703 drives the transmission gear 1702 to rotate. The transmission gear 1702 meshes with the driven gear 1701, and the transmission gear 1702 drives the driven gear 1701, so that the centrifugal column 13 and the chassis 15 start to rotate. The cleaning rod 14 with a brush is driven by the chassis 15 to continuously contact, rub and collide with the bottle chips in the cleaning device 1, and the impurities on the bottle chips are separated from the bottle chips. Under the centrifugal action of the centrifugal column 13, the impurities and the bottle chips float above the water surface, and the impurities are collected by the filter 16.

[0049] The active compressor 5 is composed of a first telescopic rod 501 and an active slider 502. The first telescopic rod 501 is an "L"-shaped telescopic rod. Both the horizontal part and the vertical part of the first telescopic rod 501 can be extended. One end of the horizontal part of the first telescopic rod 501 is connected to the active shaft 3, and one end of the vertical part of the first telescopic rod 501 is connected to the active slider 502.

[0050] The driven compressor 6 is composed of a second telescopic rod 601 and a driven slider 602. The second telescopic rod 601 is an "L"-shaped telescopic rod. Both the horizontal and vertical parts of the second telescopic rod 601 can be telescoped. One end of the horizontal part of the second telescopic rod 601 is connected to the driven shaft 4, and one end of the vertical part of the second telescopic rod 601 is connected to the driven slider 602.

[0051] The first telescopic rod 501 of the active compressor 5 is used to adjust the length of the active shaft 5 and control the two end points of the active shaft 5 within the running track of the active shaft 5; the second telescopic rod 601 of the driven compressor 6 is used to adjust the length of the driven shaft 6 and control the two end points of the driven shaft 6 within the running track of the driven shaft 6.

[0052] At the end of the cleaning process, the vertical part of the first telescopic rod 501 shrinks downward, the driving shaft 3 moves vertically downward in the "S" shaped track 8, and the driven compressor 6 moves to the right in the translation track 7. When the first telescopic rod 501 moves downward to the end point of the first corner of the "S" shaped track 8, the first telescopic rod 501 stops shrinking, and the active compressor 5 starts to move horizontally along the "S" shaped track 8 until the driven compressor 6 moves horizontally to the first corner of the "S" shaped track 8. The driven compressor 6 stops moving horizontally, and the second telescopic rod 601 starts to shrink vertically downward. At the same time, after the driven shaft 4 moves vertically downward in the "S" shaped track 8 to the end point of the first corner of the "S" shaped track 8, the second telescopic rod 601 stops shrinking. At this time, the driving shaft 3 reaches the second corner of the "S" shaped track 8.

[0053] The first telescopic rod 501 of the active compressor 5 is used to adjust the length of the active shaft 5 and control the two end points of the active shaft 5 within the running track of the active shaft 5; the second telescopic rod 601 of the driven compressor 6 is used to adjust the length of the driven shaft 6 and control the two end points of the driven shaft 6 within the running track of the driven shaft 6.

[0054] The water pipe 12 drains water, and the bottle pieces are located on the surface of the conveyor belt 3 as the water level drops, and the drainage ends. The conveyor belt 3 is in the "S" shaped track 8, the driving shaft 3 is located at the second corner of the "S" shaped track 8, and the driven shaft 4 is located at the end of the first corner of the "S" shaped track 8. The first telescopic rod 501 and the second telescopic rod 601 are repeatedly contracted and stretched in the vertical direction at the same time, and the conveyor belt 3 also repeatedly drops and rises in the vertical direction in the "S" shaped track 8, ensuring that the driving shaft 3 and the driven shaft 4 are in the "S" shaped track 8, and the driving shaft 3 and the driven shaft 4 do not collide with the "S" shaped track. The water on the bottle pieces falls due to repeated rise and fall in the vertical direction.

[0055] After the drying process is completed, the side door 9 on the machine body rotates through the shaft 10 at the bottom, and the side door 9 is opened. Then the first telescopic rod 501 shrinks vertically downward, and the driving shaft 3 also drops vertically. The driven compressor 6 moves horizontally along the "S"-shaped track 8. The bottle pieces on the conveyor belt 3 are transported from the drying and transporting device 11 to the crushing and melting device 18 under the movement of the conveyor belt 3. When the driving shaft 3 reaches the end of the second corner of the "S"-shaped track 8, the first telescopic rod 501 stops shrinking, the active compressor 5 moves horizontally in the translation track 1, and the active shaft 3 starts to move toward the end of the "S"-shaped track 8. When the driven shaft 4 reaches the second corner of the "S"-shaped track 8, the driven compressor 6 stops horizontal movement, and the second telescopic rod 601 starts to shrink vertically downward until the driven shaft 4 reaches the end of the second corner of the "S"-shaped track 8. At this time, the active compressor 5 and the driven compressor 6 stop moving, and the bottle pieces are all transported to the crushing and melting device 18 under the action of the conveyor belt 3.

[0056] The horizontal part of the first telescopic rod 501 and the horizontal part of the second telescopic rod 601 are stretched horizontally outward at the same time, the length of the driving shaft 3 and the driven shaft 1 increases, and the two ends of the driving shaft 3 and the driven shaft 4 reach the translation track 7, the horizontal part of the first telescopic rod 501 and the horizontal part of the second telescopic rod 601 stop stretching, the vertical part of the first telescopic rod 501 and the vertical part of the second telescopic rod 601 are stretched upward to the highest point and are level with the initial position of the "S" shaped track 8, the vertical part of the first telescopic rod 501 and the vertical part of the second telescopic rod 601 stop stretching, the horizontal part of the first telescopic rod 501 and the horizontal part of the second telescopic rod 602 begin to shrink horizontally inward to the driving shaft 3 and the driven shaft 4 to the "S" shaped track 8, and after the transportation is completed, the side door 9 is closed under the rotation of the bottom shaft 10.

[0057] The crushing and melting device 18 includes a box body 1806, a crushing gear roller 1802, a melting roller and a collecting device. The box body 1806 is a box body 1806 without an end cover. The box body 1806 includes a crushing gear roller 1802, a melting roller and a collecting device. The crushing gear roller 1802 is inside the crushing and melting device 18, the melting roller is below the crushing gear roller, and the collecting device is below the melting roller.

[0058] The crushing gear roller 1802 is rotationally connected to the box body 1806 through an axis. There are several crushing gear rollers, which are evenly distributed in a row. Below the crushing gear roller 1802 is a melting roller, which is divided into a primary melting roller 1803 and a secondary melting roller 1804. The primary melting roller 1803 and the secondary melting roller 1804 are both rotationally connected to the box body 1806 through an axis. The secondary melting roller 1804 is below the primary melting roller 1803. The collecting device is composed of an inclined plate 1805 and an "L"-shaped tube 1801. The inclined plate 1805 is inside the box body 1806. The high side of the inclined plate 1805 is connected to the box body 1806, and the low side of the inclined plate 1805 is connected to the "L"-shaped tube 1801. The "L"-shaped tube 1801 is connected to the outside of the machine body and communicates with the box body 1806.

[0059] When the cleaned bottle flakes are dried and transported to the crushing and melting device 18, the bottle flakes are crushed into fragments after passing through the crushing gear roller 1802. The fragments pass through the crushing gear roller 1802 to the first-stage melting roller 1804, where the fragments are heated, the temperature rises, the fragments begin to melt, and become liquid. They pass through the first-stage melting roller 1803 to the second-stage melting roller 1804. Some tiny bottle flake particles that are not evenly melted also pass through. These tiny particles are evenly melted after being heat treated by the second-stage melting roller 1804 and pass through the second-stage melting roller 1804 to the inclined plate below. Due to the inclination angle of the inclined plate 1805, the evenly molten liquid gathers together and flows out through the "L"-shaped tube 1801, thereby achieving the purpose of even melting after the impurities in the bottle flakes are screened out.

[0060] Working principle of the present invention:

[0061] The motor 1703 is started, and the cleaning device 11 starts to work. The motor 1703 drives the transmission gear 1702 in the transmission device 17 to start rotating through the shaft connection. As the transmission gear 1702 rotates, the transmission gear 1702 is driven by the meshing of the driven gear 1701, and the driven gear 1701 rotates around the axis. Driven by the chassis 15, the cleaning rod 14 with a brush also moves and works. During the centrifugal process, the impurities on the bottle chips are constantly in contact with the brush, and the friction and collision cause the impurities on the bottle chips to fall off. Then, the impurities on the bottle chips are separated from the bottle chips under the action of the centrifugal column 13. After the impurities are separated from the bottle chips, the bottle chips float on the water surface and are gathered by the filter screen 16 on the inner wall of the cleaning device 11.

[0062] The active slider 502 performs horizontal sliding motion outside the translation track 7, which drives the first telescopic rod 501. The first telescopic rod 501 controls the length of the active shaft 3 by stretching and contracting the length in the horizontal direction. The first telescopic rod 501 controls the height of the active shaft 3 by stretching and contracting the length in the vertical direction.

[0063] When the driven compressor 6 inside the translation track 7 is working, the driven slider 602 slides horizontally in the translation track 7, which will drive the second telescopic rod 601. The second telescopic rod 601 controls the length of the driven shaft 4 by stretching and contracting the length in the horizontal direction. The second telescopic rod 601 controls the height of the driven shaft 4 by stretching and contracting the length in the vertical direction.

[0064] The first telescopic rod 501 contracts vertically downward, and at the same time, the active shaft 3 descends vertically in the "S" shaped track 8, and at the same time, the driven compressor 6 moves to the right in the translation track 7. When the active compressor 5 moves downward to the end point of the first corner of the "S" shaped track 8, the first telescopic rod 501 stops contracting vertically downward, and the active compressor 5 starts to move horizontally along the "S" shaped track 8 until the driven compressor 6 moves horizontally to the first corner of the "S" shaped track 8. Then, the driven compressor 6 stops moving horizontally, and the second telescopic rod 601 starts to contract vertically downward. At the same time, after the driven shaft 4 moves vertically downward in the "S" shaped track 8 to the end point of the first corner of the "S" shaped track 8, the second telescopic rod 601 stops contracting vertically downward. At this time, the active shaft 3 reaches the second corner of the "S" shaped track 8.

[0065] The water pipe 12 drains water, and the bottle pieces are located above the conveyor belt 3 as the water level drops. The water discharge is completed. The conveyor belt 3 is in the "S"-shaped track 8, the driving shaft 3 is located at the second corner of the "S"-shaped track 8, and the driven shaft 4 is located at the end of the first corner of the "S"-shaped track 8. The first telescopic rod 501 of the driving compressor 5 and the second telescopic rod 601 of the driven compressor 6 are stretched and contracted in the vertical direction at the same time, and the conveyor belt 3 repeatedly rises and falls in the vertical direction in the "S"-shaped track 8. Ensure that the driving shaft 3 and the driven shaft 4 are in the "S"-shaped track 8, and the driving shaft 3 and the driven shaft 4 do not collide with the "S"-shaped track 8, and the water on the bottle pieces falls due to the inertia of repeated rise and fall.

[0066] The side door 9 realizes a rotational relationship with the machine body through the shaft 10 , and one end of the “L”-shaped baffle 19 is installed on the drying and transporting device 1 , and the other end of the “L”-shaped baffle 19 is installed on the box body 1806 .

[0067] The side door 9 on the machine body rotates through the shaft 10 at the bottom, and the first telescopic rod 501 of the active compressor 5 contracts vertically downward. At the same time, the active shaft 3 moves vertically downward, and the driven compressor 6 moves horizontally along the "S" shaped track 8. The bottle chips on the conveyor belt 3 are transported from the drying and transporting device 11 to the crushing and melting device 18 under the movement of the conveyor belt 3. When the active shaft 3 reaches the end of the second corner of the "S" shaped track 8, the first telescopic rod 501 stops telescoping downward, the active compressor 5 moves horizontally in the translation track 1, and the active shaft 3 starts to move toward the end point of the "S" shaped track 8. When the driven shaft 4 reaches the second corner of the "S" shaped track 8, the driven compressor 6 stops horizontally moving, and the second telescopic rod 601 starts to contract vertically downward until the driven shaft 4 reaches the end of the second corner of the "S" shaped track 8. At this time, the active compressor 5 and the driven compressor 6 stop moving, and the bottle chips are all transported to the crushing and melting device 18 under the action of the conveyor belt 3.

[0068] The conveyor belt 2 is in the "S" shaped track 8, the driving shaft 3 is located at the second corner of the "S" shaped track 8, and the driven shaft 3 is located at the end of the first corner of the "S" shaped track 8. The first telescopic rod 501 of the active compressor 5 and the second telescopic rod 601 of the driven compressor 6 are repeatedly stretched and contracted in the vertical direction at the same time. The conveyor belt 2 also repeatedly rises and falls in the vertical direction in the "S" shaped track 8. The side door 9 is closed under the rotation of the shaft 10 at the bottom of the side door. The "L" shaped baffle 19 prevents the bottle pieces from falling during transportation, ensuring that all of them fall into the crushing and melting device 18.

[0069] The crushing gear roller 1802 in the box 1806 is connected to the box 1806 by an axis to achieve a rotational relationship in the crushing and melting device 18. It is distributed in a row, and the two crushing gear rollers 1802 rotate in opposite directions. Below is the melting roller, which is divided into a primary melting roller 1803 and a secondary melting roller 1804. Both are connected to the box 1806 by an axis to achieve a rotational relationship. The secondary melting roller 1804 is below the primary melting roller 1803, and the primary melting roller 1803 and the secondary melting roller 1804 rotate in opposite directions. The collecting device is composed of an inclined plate 1805 and an "L"-shaped tube 1801. The inclined plate 1805 is inside the box 1806, the high side of the inclined plate 1805 is connected to the machine body, and the low side of the inclined plate 1805 is connected to the "L"-shaped tube 1801. The "L"-shaped tube 1801 is connected to the box 1806 outside the machine body.
