Technical Field

[0001] The utility model relates to the technical field of plastic bottle production equipment, in particular to a labeling device for producing environmentally friendly plastic bottles. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding corresponding organic solvents, they are heated at high temperature and then passed through plastic molds through blow molding, extrusion blow molding, or injection molding. They are plastic containers. They are mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oils, pesticides and veterinary drugs. Plastic bottles are not easy to break, low cost, high transparency, and food-grade raw materials.

[0003] During the production process of plastic bottles, they need to be labeled. Dust and other impurities may adhere to the plastic bottles. If they are not cleaned before labeling, the labeling quality may be affected. Therefore, an environmentally friendly plastic bottle production labeling device is urgently needed to solve the above problem. Utility Model Content

[0045] The label paper passes through the rotating roller 7 and abuts against it, and the plastic bottle is placed on the conveyor belt 3. The intermittent rotating mechanism drives the conveyor belt 3 to move intermittently, and the conveyor belt 3 intermittently conveys the plastic bottle. When the plastic bottle is conveyed to the same vertical plane as the rotating roller 7, the conveyor belt 3 stops moving, and the limiting mechanism moves to cooperate with the rotating roller 7 to abut and limit the plastic bottle. The rotating roller 7 fixes one end of the label paper on the plastic bottle. The power member 1 (not shown in the figure) drives the rotating roller 7 to rotate. The rotating roller 7 drives the label paper to move and drives the plastic bottle to rotate at the same time, ensuring that the label paper adheres to the plastic bottle. The purging mechanism purges the body of the plastic bottle to purge the dust adhered to the body of the plastic bottle to prevent the dust from affecting the sticking of the label paper. The power member 1 can be a stepper motor, a servo motor, etc.
