The housing of the tenth drive motor is fixedly arranged on the frame 10, and the rotating shaft of the tenth drive motor is fixedly connected to the fourth conveyor roller.

[0068] After the yarn on the yarn bobbin is cleaned, the cylinder slide block 36 of the rodless cylinder 35 moves to the right, driving the driving connecting rod 32 and the roller 33 to drive the yarn bobbin to slide along the slide rail 31 toward the fourth conveyor belt 96. When the yarn bobbin moves on the fourth conveyor belt 96, the telescopic rod of the second driving cylinder 34 drives the driving connecting rod 32 and the roller 33 to move upward to release the yarn bobbin. The yarn bobbin enters the third conveyor belt 88 from the feeding port 97 on the third conveyor belt 88 under the transportation of the fourth conveyor belt 96. The conveyor belt 88 first passes through the color detector 91, and the color detector 91 records the corresponding color and time. According to the pre-programmed program and the calculation of the yarn tube stroke, after the yarn tube of the corresponding color passes through the corresponding sorting cylinder 92, the telescopic rod of the sorting cylinder 92 extends through the first sorting port 93 and pushes the yarn tube from the corresponding second sorting port 94 to separate from the third conveyor belt 88. The yarn tube separated from the third conveyor belt 88 falls along the guide trough 95 into the collection container below the guide trough 95.

[0069] The workbench 25 is covered with an isolation cover 98, which is transparent, so that the operator can observe the internal operation and prevent the yarn from flying everywhere under the influence of the airflow. The isolation cover 98 is arranged on the frame 10, and the isolation cover 98 is provided with a passage 99 for the first conveyor belt 26 to convey the yarn bobbin to pass through and for the driving connecting rod 32 to drive the yarn bobbin to pass out.

[0070] A controller 100 for controlling the operation of the equipment is arranged outside the frame 10, and the rodless cylinder 35, the color detector 91, the sorting cylinder 92, the first drive motor 27, the second drive cylinder 34, the fourth drive cylinder 44, the fifth drive motor 48, the sixth drive cylinder 57, the seventh drive motor 60, the eighth drive motor 77, the ninth drive motor, and the tenth drive motor are all connected to the controller 100 by signal.

[0071] The working principle of the present invention is as follows: the controller 100 is programmed accordingly, the device is started, the controller 100 controls the first drive motor 27, the eighth drive motor 77, the ninth drive motor, and the tenth drive motor to rotate, and drives the first conveyor belt 26, the second conveyor belt 21, the third conveyor belt 88, and the fourth conveyor belt 96 to start moving.

[0072] The yarn bobbin to be cleaned is placed on the second conveyor belt 21 and transported under the drive of the second conveyor belt 21. At the end of the second conveyor belt 21, the yarn bobbin falls into the guide groove and falls vertically onto the first conveyor belt 26 under the action of the adjustment channel 24.

[0073] After the yarn tube falls vertically onto the first conveyor belt 26, the first conveyor belt 26 continues to convey the yarn tube. When the first conveyor belt 26 conveys the yarn tube to move below the rodless cylinder 35, the controller 100 controls the telescopic rod of the second driving cylinder 34 to extend and drive the driving connecting rod 32 and the roller 33 to extend into the yarn tube. The rodless cylinder 35 controls the driving connecting rod 32 to slide to the right along the slide rail 31. Under the action of the roller 33, the yarn tube is centered on the slide rail 31. After the yarn tube slides between the first positioning block 37 and the second positioning block 38, the controller 100 controls the rodless cylinder 35 to stop moving, and at the same time controls the fourth driving cylinder 44 and the sixth driving cylinder 57 to act. The telescopic rod of the fourth driving cylinder 44 extends to drive the driving connecting rod 32 and the roller 33 to extend into the yarn tube. The block 45 and the upper positioning block and the lower positioning block move toward the yarn tube, and the yarn tube is positioned between the first positioning block 37 and the second positioning block 38. The telescopic rod of the sixth driving cylinder 57 is controlled to extend to drive the driving plate 58 and the cutting tool 51 to move toward the yarn tube, and the upper limit baffle 52 and the lower limit baffle 521 are respectively pressed against the upper end and the lower end of the yarn tube. Then the controller 100 controls the seventh driving motor 60 to rotate forward, and the seventh driving motor 60 drives the rotating disk 61 to rotate forward. The rotation of the rotating disk 61 drives the driving rod 62 to move. The movement of the driving rod 62 drives the threaded rod 63 to slide downward along the first guide groove 54. The threaded rod 63 drives the cutting tool 51 to slide downward along the guide groove to cut the remaining yarn on the yarn tube.

[0074] After the cutting is completed, the controller 100 controls the eighth drive motor 77 to rotate, and the rotation of the eighth drive motor 77 drives the drive disk 74 to rotate, and the rotation of the drive disk 74 drives the first connecting rod 75 to rotate, and the free end of the first connecting rod 75 drives the second connecting rod 76 to swing, and the second connecting rod 76 drives the hanging brush 72 and the paddle 73 to move downward along the outer wall of the yarn tube to peel the yarn on the yarn tube off the yarn tube, and then with the further rotation of the drive disk 74, it moves upward to reset, and the stripped yarn falls freely through the opening 30 and falls into the recovery frame 78. The yarn that falls on the slide rail 31 will be adsorbed into the recovery frame 78 when the negative pressure suction pipe 84 is working, and the weighing scale 86 will weigh the yarn in the recovery frame 78.

[0075] The controller 100 controls the actions of the fourth drive cylinder 44 and the sixth drive cylinder 57. The telescopic rod of the fourth drive cylinder 44 drives the drive block 45 and the upper positioning block and the lower positioning block to retract for reset. The telescopic rod of the sixth drive cylinder 57 drives the drive plate 58 and the cutting tool 51 to retract for reset. At the same time, the seventh drive motor 60 is controlled to reverse and drive the cutting tool 51 to slide upward along the guide plate 53 for reset and control the cylinder slider 36 of the rodless cylinder 35 to continue to move to the right. The rodless cylinder 35 drives the driving connecting rod 32 and the roller 33 to drive the yarn tube to slide along the slide rail 31 toward the fourth conveyor belt 96. When the yarn tube moves on the fourth conveyor belt 96, the controller 100 controls the telescopic rod of the second drive cylinder 34 to drive the driving connecting rod 32 and the roller 33 to move upward to release the yarn tube.

[0076] The yarn bobbin enters the third conveyor belt 88 from the feed port 97 on the third conveyor belt 88 under the transport of the fourth conveyor belt 96, and first passes through the color detector 91 under the transport of the third conveyor belt 88. The color detector 91 records the corresponding color and time, and feeds back this information to the controller 100. The controller 100 calculates the stroke of the yarn bobbin. After the yarn bobbin reaches the sorting cylinder 92 for sorting the corresponding color, the controller 100 controls the telescopic rod of the sorting cylinder 92 to extend through the first sorting port 93 and then push the yarn bobbin to detach from the third conveyor belt 88 from the corresponding second sorting port 94. The yarn bobbin detached from the third conveyor belt 88 falls along the guide trough 95 into the collection container below the guide trough 95.

[0077] The cleaned yarn bobbins and yarns are sorted and recycled.
