Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bottle labeling equipment, in particular to a bottle automatic labeling device for household care products. BACKGROUND

[0002] In the field of household care products, such as laundry detergent, shampoo, shower gel, etc., a unique designed bottle is often used to improve product recognition and aesthetics. In addition to the conventional round bottle and square bottle, some irregular bottle bodies are designed, such as "flat bottle" with an oval cross-section, and some square bottles with complex structures such as outwardly convex or inwardly concave sides. Labeling is one of the key processes in the packaging of such products during the processing of household care products. The label not only carries product information, but also is an important embodiment of brand image. Therefore, the precision, flatness and firmness of bottle labeling are highly required.

[0003] The existing bottle automatic labeling device has been relatively mature for labeling around some regular round bottles. Its working principle is usually to convey the bottle through a conveyor belt, and when the bottle triggers a sensor, the labeling mechanism performs an action to label the bottle. However, this labeling method cannot accurately label a specific position of the bottle, especially in the process of labeling flat bottles or square bottles. During the transmission of the bottle, the posture of the bottle cannot be corrected and accurately positioned, and during the transmission of the bottle, the bottle is prone to deflection or misplacement due to vibration or collision, etc., resulting in the side of the bottle facing the labeling label peeling plate cannot be kept consistent; when labeling a specific position of a flat bottle or a square bottle is needed, since the existing labeling machine cannot accurately position the bottle, the label is often misaligned or offset, often requiring secondary correction or label peeling rework, not only increasing the cost of labeling, affecting the labeling effect, but also leading to low efficiency of the entire labeling production line.

[0036] Working principle: when labeling, the bottle body 2 is first inserted into the placing groove 51 of the clamping base 5 at the feeding end of the transmission base 1, and the two sides of the bottle body 2 are moved downward along the two side baffles 56, at this time, the specific position of the bottle body 2 to be labeled faces the side of the transmission base 1 provided with the label conveying assembly 13; When the lower end of the bottle body 2 contacts the push plate 62, the bottle body 2 is continuously pushed downward along the two side baffles 56 at this time, the push plate 62 is moved downward until the push plate 62 is clamped into the contraction groove 59, in this process, the push plate 62 drives the driving tooth plate 6 to slide downward along the lifting groove 53 through the lifting column 61, the driving tooth plate 6 drives the limiting block 63 to move downward, and the limiting block 63 extrudes the reset spring 64; The driving tooth plate 6 drives the two half-ring gears 74 to rotate in the process of moving downward, at this time, the two half-ring gears 74 rotate in opposite directions, the two half-ring gears 74 drive the two concave swing frames 73 to swing towards each other, the two concave swing frames 73 drive the driving column 75 to move synchronously, at this time, the driving column 75 slides along the driving groove 72 from downward to upward, and the driving column 75 pushes the clamping component 7 to move close to the bottle body 2, the clamping component 7 drives the guide sliding plate 76 to slide along the clamping base 5, so that the clamping component 7 can stably move, and the two clamping components 7 synchronously move close to the bottle body 2; When the lower end of the bottle body 2 is in contact with the bottom of the placing groove 51, the upper end of the push plate 62 is at the same level as the bottom of the placing groove 51, at this time the drive tooth plate 6 moves to the bottom of the lifting groove 53, at this time the drive tooth plate 6 cannot continue to move downward, and the two clamping mechanisms are clamped on the two sides of the bottle body 2. At this time, the two clamping parts 7 and the two side clamping plates 71 are clamped on the two sides of the bottle body 2, firmly clamping and locking the bottle body 2.

[0037] After the limiting block 63 moves downward by a distance, the limiting block 63 first contacts the guide inclined surface of the locking block 81, at this time when the limiting block 63 continues to move downward, the limiting block 63 extrudes the guide inclined surface, thereby pushing the locking block 81 away from the limiting block 63 to move, the locking block 81 drives the L-shaped connecting plate 8 to slide along the L-shaped groove 57, and the L-shaped connecting plate 8 drives the extrusion ring 84 to slide into the circular groove 58 through the slide rod 82, and the extrusion ring 84 extrudes the return spring 83.
