[0002] Plastic bottle sleeve labels are commonly used for label packaging of mineral water bottles. They can conveniently display information such as the brand, product name, and production date of the mineral water, helping consumers better understand and choose the product. Sleeve label plastics have good printability and adhesion, and can be easily printed with various patterns and texts, enhancing the aesthetics and recognition of the product, making it easier for consumers to identify and remember the brand.

The opposite inner sides of the two label pulling blocks 57 are provided with suction heads, and the suction heads are connected to the outside through pipes.

The middle part of the mounting groove 1 on the rear side of the mounting block 51 is rotatably connected with a gear 4 596. The gear 4 596 is respectively meshed with the rack 2 595 and the rack 1 594. The right side of the rack 2 595 is provided with a slip ring 591, and the slip ring 591 extends to the outside of the mounting groove 1 The middle part of the sliding column 55 is slidably connected to the inside of the slip ring 591. The labeling mechanism 5 also includes a driving assembly 58. The driving assembly 58 includes a gear 1 581, a gear 2 582 and a gear 3 583. The rear side of the turntable 53 is provided with a gear 1 581. The middle part of the rear side of the mounting plate 4 is rotatably connected with a gear 2 582. The gear 2 582 is meshed with the gear 1 581 on the right side. The left end of the rear side of the mounting plate 4 is rotatably connected with a gear 3 583. The right side of the gear 3 583 is meshed with the gear 1 581 on the left side. The left side of the gear 3 583 is meshed with the gear 2 582. The driving assembly 58 also includes a motor 584. The motor 584 is arranged on the rear side of the housing 1. The output shaft of the motor 584 passes through the circular hole on the rear side of the housing 1 and is connected to the gear The middle part of the rear side of the second gear 582 is fixedly connected, the input end of the motor 584 is electrically connected to the output end of the single-chip computer 6, and then the external negative pressure pump is turned on to suck the plastic label through the suction head, and then the motor 584 is turned on through the single-chip computer 6. The motor 584 drives the second gear 582 to rotate the transmission gear three 583 clockwise and the gear one 581 on the right to rotate counterclockwise. The gear three 583 drives the gear one 581 on the left to rotate clockwise, thereby driving the two turntables 53 to drive the rotating rod 54 to rotate in opposite directions at the same time. At the same time, the guide groove 56 will toggle the slide post 55 to slide in the second slide groove and slide downward along the guide groove 56, driving the pull block 57 to pull the plastic label downward. When the slide post 55 slides to the bottom of the guide groove 56, the motor 584 is controlled to stop running through the single-chip computer 6.The external negative pressure pump is then turned off, and the suction head no longer absorbs the plastic label. The motor 584 is then turned on again via the single-chip microcomputer 6. Since the guide slot 56 is an L-shaped slot, it forces the slide post 55 to slide away from the center of the mounting block 51, simultaneously pulling the slip ring 591. This drives the second rack 595, which drives the second label cutter 593 to slide rightward within the third chute. The fourth transmission gear 596 rotates the first transmission rack 594, which drives the first label cutter 592 to slide leftward within the fourth chute, thereby severing the plastic label. The severed plastic label is then placed on the surface of the plastic bottle, completing the labeling process. The label-pulling block 57 then pulls the label downward, cooperating with the label-cutting assembly 59 to cut the label, achieving automatic labeling of the plastic bottle and saving manpower.

[0027] The working principle of the plastic bottle body labeling device provided by the present invention is as follows: when labeling a plastic bottle, the plastic label is first pulled out from the label roll 10, and then stretched and sleeved on the surface of the central column 52 by the tension roller 3, and then the knob on the right side of the bidirectional screw rod 9 is rotated to drive the bidirectional screw rod 9 to rotate and drive the two slide bars 8 to slide towards each other, so that the rollers contact the plastic label, and then the plastic bottle is placed on the belt surface of the electric conveyor belt 2, and the electric conveyor belt 2 is turned on by the single-chip microcomputer 6. When the plastic bottle is conveyed to the lower end of the central column 52, the electric conveyor belt 2 is controlled by the single-chip microcomputer 6 to pause the conveying, and then the external negative pressure pump is turned on to suck the plastic label through the suction head, and then the motor 584 is turned on by the single-chip microcomputer 6. The motor 584 drives the gear 2 582 to rotate clockwise, the transmission gear 3 583 and the gear 1 581 on the right to rotate counterclockwise, and the gear 3 583 drives the gear 1 581 on the left to rotate clockwise, thereby driving the two turntables 5 When the slider 55 reaches the bottom of the guide groove 56, the motor 584 is first controlled by the single chip microcomputer 6 to stop running, and then the external negative pressure pump is turned off, the suction head no longer absorbs the plastic label, and then the motor 584 is turned on again by the single chip microcomputer 6. Since the guide groove 56 is an L-shaped groove, the guide groove 56 will at this time toggle the slider 55 to slide to the side away from the center of the mounting block 51, and pull the slip ring 591. The slip ring 591 drives the rack 2 595 to drive the label cutting knife 2 593 to slide to the right in the slide groove 3, and the transmission gear 4 596 rotates the transmission rack 1 594 to drive the label cutting knife 1 592 to slide to the left in the slide groove 4, thereby cutting off the plastic label. The cut plastic label will be sleeved on the surface of the plastic bottle, thereby completing the plastic bottle sleeve.

[0028] It is worth noting that the single-chip microcomputer 6 disclosed in the above embodiment can be a 51 series single-chip microcomputer, the motor 584 can be a THA130302B servo motor, and the electric conveyor belt 2 can be freely configured according to the actual application scenario. The single-chip microcomputer 6 controls the operation of the motor 584 and the electric conveyor belt 2 using methods commonly used in the prior art.
