Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to a labeling device for plastic bottles. Background Technology

[0002] A labeling machine is a device that affixes rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. Labeling machines are an indispensable part of modern packaging. In the production and processing of plastic bottles, labels are usually affixed to the plastic bottles to distinguish them from products on the market.

[0003] For example, Chinese utility model patent CN219487946U proposes a labeling mechanism for plastic bottle production, including a table and a labeling machine body. A transmission belt is installed on the top of the table, and the labeling machine body is installed on the top of the table. A first electric push rod is installed on the top of the table, and the output end of the first electric push rod is connected to a first movable frame. A first roller is installed on one side wall of the first movable frame via a bearing, and a first pulley is installed at the bottom of the first roller. A first motor is installed on one side wall of the first movable frame. The advantage of this solution is that, through the arrangement of the first electric push rod, first movable frame, first roller, first pulley, first motor, second pulley, second roller, fixed plate, second electric push rod, U-shaped frame, screw, nut, and sponge block, the surface of the plastic bottle can be cleaned, making the surface cleaner and the labeling effect better, preventing labeling from falling off, thus making it highly practical. However, during dust removal, the dust in the dust removal device accumulates, which may prevent subsequent plastic bottles from being cleaned.

[0004] In existing technologies, a rotating roller is used to make the plastic bottle rotate on the conveyor belt. However, when the plastic bottle is pushed, the top is not clamped, which can easily cause it to tip over or be misaligned. Utility Model Content

[0060] When using, through the start clamping cylinder 61, make clamping cylinder 61 drive lifting plate 62 to descend, make lifting plate 62 drive the clamping rod 66 in the bottom to descend, make clamping rod 66 label top clamping, when lifting plate 62 descends, connecting rod 76 drives push block no. 75 to descend, make push block no. 75 drive push block no. 77 horizontal displacement, make push block no. 75 drive push bottle rack 73 one side push bottle rack 73 movement, make push bottle roller 74 on push bottle rack 73 horizontal movement, make push bottle roller 74 push bottle body, make bottle body be limited between sponge roller 40 and push bottle roller 74 extrusion and fit, simultaneously, make bottle body can rotate.

[0061] Specifically, the top clamping assembly 60 further comprises a threaded sleeve 63 fixedly connected to one end of the lifting plate 62, a threaded rod 64 threadedly connected to the inner side wall of the threaded sleeve 63, the bottom end of which is connected to the top end of a clamping rod 66, and an adjusting knob 65 fixedly connected to the top end of the threaded rod 64. By arranging the threaded sleeve 63, the threaded rod 64 and the adjusting knob 65, the height of the top clamping assembly 60 can be adjusted according to the height of the bottle. When adjusting, the adjusting knob 65 is rotated to drive the threaded rod 64 to rotate, and the clamping rod 66 at the bottom end of the threaded rod 64 is raised or lowered to adjust the height.
