By brand-new design for the label removing machine, this system enables the labelremoving and cleaning machine to implement strong cleaning while label removing; thebouncing separation screen is newly designed to separate the cleaning water, labels, andimpurities from the main materials; and the cleaning water passes through the filtrationsystem in the cleaning liquid separator, so that the cleaning water is completely separatedfrom the labels and impurities, and large amount of the cleaning water can be recycled andreused. The system design integrates the functions implemented by the combination ofnumerous conventional independent functional devices through the development design ofmultifunctional devices and system optimization, thereby reducing the use of equipment,greatly reducing equipment investment and operating costs, and achieving improvement incleaning performance.2. The materials enter the cleaning chamber in the drum from the feed port, the drivingdevice drives the rotor to rotate. Through the angled moving blades on the rotor, waste plasticbottles are repeatedly rubbed between the plurality of fixed blades on the inner wall of thedrum and the plurality of moving blades on the outer sidewall of the rotor, so that the labelscan be peeled off from the bottle bodies by fully rubbing. The moving blades are arranged onthe outer sidewall of the rotor in a spiral order, and can further push and transport the wasteplastic bottles to the discharge port. In the process of the bottle materials being pushed by themoving blades, the labels are peeled off through squeezing and scraping formed between thebottle materials and the fixed blades, until the bottle materials are discharged from thedischarge port.3. The geared motor drives the plurality of bouncing shafts to rotate through a chain,and the bouncing shafts drive the plurality of bouncing screening sheets to rotate. When thematerials (bottles after cleaning, including bottles, labels, water, bottle caps, and otherimpurities) are in contact with the bouncing screening sheets, because the bottle has largeweight and volume and small contact area, the bottle can be bounced by the bouncingscreening sheets and bounce upwards along the screening sheets on the roller on the screeningsurface, and because the weight of the bottle is relatively large, the surface is smooth, and thecontact area between the bottle body and the screening sheet is small, the bottle cannot bedriven to the left for separation by the screening sheet, and can only slide down whilejumping along the screening sheet to the right. The label cannot be bounced due to itslightness and softness, the weight is small, and the contact area is large, so the label is drivenalong the screening sheet to the left. Other impurities, water, bottle caps, and othersmall-sized materials fall from the gap between two adjacent bouncing screening sheets, arecollected in the water receiving tray of the lower layer, pass through a pipe, and flow, with thewater flow, to a filtration equipment in the cleaning liquid separator. The setting of a coverplate effectively prevents the bottles from bouncing out of the bouncing separation screen,thereby improving practicability.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a schematic diagram of an integral structure of the present invention;FIG. 2 is a schematic structural diagram of a label removing and cleaning machineaccording to the present invention;FIG. 3 is a cross-sectional view of a label removing and cleaning machine according tothe present invention;FIG. 4 is a schematic structural diagram of a rotor according to the present invention;FIG. 5 is a schematic structural diagram of a moving blade according to the presentinvention;FIG. 6 is a schematic plan view of a marking disc according to the present invention;FIG. 7 is a side view of a marking disc according to the present invention;FIG. 8 is a schematic structural diagram of a bouncing separation screen according tothe present invention;FIG. 9 is a schematic structural diagram of a bouncing shaft according to the presentinvention; andFIG. 10 is a schematic plan view of a bouncing screening sheet according to the presentinvention.DETAILED DESCRIPTIONA plurality of implementations or examples are provided below to implement differentfeatures of this disclosure.

The Reuleaux triangle, also called "Reuleaux triangle", "Reuleaux triangle", and "arctriangle", is a special triangle. The vertexes of a regular triangle are as the centers and the sidelength is as the radius to draw arcs, and the curved triangle formed by these three arcs iscalled the Reuleaux triangle. The characteristic of the Reuleaux triangle is: constant width inany direction, that is, it can freely rotate between two parallel lines whose distance is equal tothe arc radius a (equal to the side length of the regular triangle), and always keep in contactwith the two straight lines. The mechanical processing industry uses this characteristic tomake the cross section of a drill bit into the shape of the Reuleaux triangle, to drill a squarehole on a part. This characteristic was discovered by Reuleaux when studying mechanicalclassification.The implementation principle of this embodiment is: by brand-new design for the labelremoving machine, this system enables the label removing and cleaning machine 2 toimplement strong cleaning while label removing; the bouncing separation screen 3 is newlydesigned to separate the cleaning water, labels, and impurities from the main materials; andthe cleaning water passes through the filtration system in the cleaning liquid separator 4, sothat the cleaning water is completely separated from the labels and impurities, and largeamount of the cleaning water can be recycled and reused. The system design integrates thefunctions implemented by the combination of numerous conventional independent functionaldevices through the development design of multifunctional devices and system optimization,thereby reducing the use of equipment, greatly reducing equipment investment and operatingcosts, and achieving improvement in cleaning performance.The features of the several embodiments summarized above make those skilled in theart can better understand aspects of this application.
