Description

Technical Field

[0001] The invention relates to the technical field of PET bottle flake processing, in particular to dry PET bottle flake cleaning equipment. Background Art

[0002] PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range, and its long-term use temperature can reach 120°C. It has excellent electrical insulation, and its electrical properties are still good even at high temperature and high frequency. However, its corona resistance is poor, and its creep resistance, fatigue resistance, friction resistance, and dimensional stability are all very good. PET bottles cannot be degraded naturally. In order to reduce pollution and improve resource utilization, discarded PET bottles are generally recycled.

[0003] After PET bottles are crushed to form PET bottle flakes, the PET bottle flakes need to be recycled using cleaning equipment to remove floating dust and mixed debris attached to the PET bottle flakes. For example, the prior art CN215507926U proposed a new type of PET bottle flake cleaning device, and CN221288881U proposed a sedimentation type PET bottle flake cleaning structure. The above prior art uses flushing and stirring to clean the PET bottle flakes to achieve the cleaning of the PET bottle flakes.

[0041] The working principle of the present invention is: during operation, feed is fed through the feed port 18, and after the feeding is completed, the feed valve 2 is closed, and then the second motor 401 is started, and the second motor 401 starts to drive the first belt 402 and the first pulley 403 to operate, and the operation of the first belt 402 and the first pulley 403 can drive the fourth gear 602 to rotate, and the output end of the second motor 401 rotates while also driving the second belt 404 and the second pulley 405 to operate, and the operation of the second belt 404 and the second pulley 405 can drive the bottom shaft 13 to rotate, and the operation of the bottom shaft 13 can drive the sprocket 16 to rotate, and the rotation of the sprocket 16 drives the chain 15 to operate, and the operation of the chain 15 drives the shifting column 14 to move, When the shift post 14 moves downward, it drives the shift fork block 17 and the impact cylinder 8 to move downward, and the impact cylinder 8 moves downward to store force. When the shift post 14 is separated from the shift fork block 17, the impact cylinder 8 will be released, and the PET bottle flakes will be impacted upward by the elastic force of the first tension spring 9. The impacted PET bottle flakes will be hit by the rotating striking piece 606 and the striking shaft 605. When the shift post 14 moves upward, it drives the second shift fork 507 to move upward. The upward movement of the second shift fork 507 drives the rack 502 to move upward. The upward movement of the rack 502 drives the two second gears 501 to rotate. Since the tooth surfaces of the two racks 502 are arranged oppositely, the rotation directions of the two side shafts 512 are opposite, and the rotation of the side shaft 512 can drive The first synchronous wheel 508 and the first synchronous belt 509 are driven to operate, which can drive the hexagonal shaft 514 to rotate accordingly. The rotation of the hexagonal shaft 514 drives the spiral rod 515, and the spiral rod 515 cooperates with the spiral seat 517 to realize the movement of the kneading block 513, so that the kneading blocks 513 can rotate while approaching each other, and the two kneading blocks 513 turn in opposite directions, thereby realizing the kneading of the PET bottle sheets. When the shifting post 14 is separated from the second fork 507, the second fork 507 is reset under the action of the second tension spring 506, which can drive the rack 502 to reset downward, thereby driving the subordinate components to move, and then resetting the kneading block 513. Since the shifting post 14 moves downward to drive the spring The striking cylinder 8 and the lever 14 move upward to drive the sliding cross bar 505, so the movements of the striking cylinder 8 and the kneading block 513 will be performed alternately without interference. Dust and impurities can be separated by striking, kneading and striking the PET. The separated impurities and dust will move upward under the action of the rising airflow inside the chassis 1, and then be collected by the collecting component 3. The specific gravity of PET bottle pieces is relatively large and will not be sucked in. At the same time, the dust concentration detector 19 can detect the ash content inside the chassis 1 during operation, which is convenient for workers to control the cleaning situation. At the same time, the timer 20 can cooperate with the controller 21 to time the equipment, so that the cleaning time can be set according to needs.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Although this specification is described in accordance with the implementation modes, not every implementation mode includes only one technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
