Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic bottle processing and production, especially relates to a plastic bottle processing and production labeling device. BACKGROUND

[0002] Plastic bottles are most widely used in the beverage industry, including carbonated beverages, mineral water, alcoholic beverages, dairy products, milk-containing beverages, plant protein beverages, tea and juice drinks, etc. These beverages are usually packaged in bottles made of plastic materials such as PET (polyethylene terephthalate), because these materials have good transparency, barrier properties, impact resistance, durability and are not easily broken, and are often used as storage containers. During the processing and production of plastic bottles, especially before they enter the labeling process, the cleanliness of the surface of the plastic bottles is crucial to the quality of the labeling. During transportation and storage, due to environmental factors such as dust in the air, fine particles in the workshop, and static electricity that may be released by the plastic bottles themselves, the surface of the plastic bottles often has various dust, impurities and stains. These contaminants not only affect the appearance of the plastic bottles, but more importantly, they can interfere with the adhesion of the label to the surface of the plastic bottle during the labeling process, resulting in problems such as loose labeling, bubbles and even falling off, which can seriously affect the labeling quality and the overall quality of the product.

[0003] Traditional plastic bottle labeling pre-treatment often relies on manual wiping or using simple cleaning tools for surface cleaning. This method not only has low efficiency, but also has difficulty in ensuring cleaning effectiveness, especially when a large number of plastic bottles need to be processed, the limitations and deficiencies of manual cleaning become more apparent. In addition, manual cleaning can introduce new sources of pollution, such as fibers on the cleaning cloth and cleaning agent residues, which can further affect the labeling effect. In addition, during the labeling process, cleaning tools play a crucial role in cleaning the surface of the plastic bottles before labeling to ensure that the label can be successfully attached. However, as the use time increases, the cleaning tools themselves can also be contaminated with dust, stains and other pollutants, causing their cleaning effectiveness to gradually decline.

[0039] The working principle of the plastic bottle processing and production labeling device is as follows:

[0040] I. Conveying and positioning of plastic bottles

[0041] Starting of the conveying belt: when the labeling machine body 1 is started, the conveying belt 2 starts to run, the conveying belt 2 is stably supported by the support frame 21, which ensures its stable and continuous operation, and the plastic bottles to be labeled are conveyed one by one to the working area of the labeling machine;

[0042] Clamping of the positioning claw: on one side of the conveying belt 2, the positioning claw 3 starts to work, the worm gear two 11 is driven to rotate by the rotating shaft close to the labeling machine body 1 of the conveying belt 2, so as to drive the worm gear two 13 and the rotating rod two 12 to rotate together, and due to the design of the thread direction of the worm gear two 11, the positioning claw 3 is in the same direction as the conveying belt 2, through accurate design, it can clamp the plastic bottle, and ensure that the plastic bottle always maintains uniform speed during conveying, and will not deviate or fall due to external force;

[0043] II. Cleaning effect of the cleaning belt

[0044] The starting of the cleaning belt: the cleaning belt 4 is linked with the conveying belt 2 through a transmission mechanism, which is composed of a worm 8 and a worm gear 9. The worm 8 is driven by the rotating shaft in the middle of the conveying belt 2, and cooperates with the worm gear 9 to drive the rotating rod 10 to rotate. Since the thread direction of the worm 8 is opposite to that of the worm 11, the cleaning belt 4 is finally driven to move in the opposite direction of the conveying belt 2;

[0045] The cleaning process of the cleaning belt: the cleaning belt 4 closely adheres to the surface of the plastic bottle. Since the rotating direction of the cleaning belt 4 is opposite to the advancing direction of the plastic bottle, the reverse friction can drive the plastic bottle to rotate in the positioning claw 3, so as to more effectively remove the dust, impurities and stains on the surface of the plastic bottle. The material of the cleaning belt 4 is soft silica gel, so as to ensure good cleaning effect;

[0046] III. The cooperative work of the cleaning roller and the water spraying pipe

[0047] The rotation of the cleaning roller: the cleaning roller 5 is arranged on the side of the cleaning belt 4 away from the plastic bottle, and is connected with the driving pulley 14 in the rotating rod 10 through a belt drive, so as to rotate with the cleaning belt 4;

[0048] The water spraying of the water spraying pipe: the water spraying pipe 6 on the side of the cleaning roller 5 away from the cleaning belt 4 starts to spray water. The sprayed water can wet the cleaning roller 5, so as to better remove the dust and impurities on the cleaning belt 4. At the same time, appropriate water pressure can also flush away the dust and impurities on the cleaning roller 5;

[0049] The collection of the water guide cover and the sewage pipe: the water guide cover 16 is arranged at the top end of the support frame 21 close to the cleaning roller 5, and is used to collect the water sprayed by the water spraying pipe 6 and the sewage generated in the cleaning process.

[0050] IV. The drying effect of the dryer

[0051] The starting of the dryer: the dryer 7 is arranged on the side of the cleaning belt 4 close to the cleaning roller 5. When the cleaning belt 4 passes through the dryer 7, the dryer 7 will dry the cleaning belt 4 to prevent water residue from affecting the subsequent cleaning effect;

[0052] The drying process of the dryer: the dryer 7 generates hot air through the internal heating element to quickly dry the cleaning belt 4 passing through the drying box 18. The design of the dryer 7 and the drying box 18 ensures that the water on the cleaning belt 4 can be completely dried in a short time;

[0053] V. The water supply effect of the water supply machine

[0054] The start of the water machine: the bottom water inlet of the water spraying pipe 6 is communicated with the water machine 22, and the water machine 22 is responsible for providing a continuous and stable water source for the water spraying pipe 6, so as to ensure that there is enough clean water for wetting and flushing the cleaning roller 5 during the cleaning process.

[0055] The water supply process of the water machine: the water pump in the water machine 22 pumps out the clean water in the water storage tank and delivers it to the water spraying pipe 6 through the pipeline, and the water spraying pipe 6 sprays water according to the set water spraying amount and frequency, ensuring the smooth progress of the cleaning process.

[0056] Six, the overall working process

[0057] As described above, when the plastic bottle is conveyed to the front of the labeling machine, the positioning claw 3 first clamps the plastic bottle and moves forward at a constant speed with the conveying belt 2; then the cleaning belt 4 starts to work and moves in the opposite direction of the plastic bottle to clean its surface; at the same time, the water spraying pipe 6 sprays water to the cleaning roller 5 to achieve the effect of wetting and flushing; the cleaned cleaning belt 4 is dried by the drying machine 7; the water guide cover 16 and the sewage pipe 17 collect and discharge sewage; the water machine 22 continuously supplies clean water to the water spraying pipe 6; after the above series of steps, the surface of the plastic bottle is effectively cleaned, then the plastic bottle is conveyed to the labeling machine body 1 by the conveying belt 2, the positioning mechanism in the labeling machine body 1 uses high-precision sensors and a control system to accurately position the plastic bottle, ensuring that the label can be accurately and correctly attached to the predetermined position, the labeling execution mechanism stably and quickly attaches the label after the backing paper is peeled off to the surface of the plastic bottle, and the covering mechanism further flattens or rolls the attached label to make it more flat and firm. The plastic bottle with the label is sent out by the conveying belt 2, and the entire labeling process is completed.
