Description

Technical Field

[0001] This utility model relates to the field of plastic packaging machinery technology, and in particular to a bottle pretreatment system for reducing the friction of the labeling machine, specifically applied to the conveyor belt system at the front end of the labeling machine. Background Technology

[0002] Labeling machines are devices used to attach labels to bottles. They are suitable for various bottle types in the food and beverage industry, including juice, tea drinks, dairy products, purified water, condiments, beer, and sports drinks. Not only is the label placement highly accurate, but the shrinkage process also makes the bottle stand out more and enhances its shape.

[0003] However, when existing labeling machines process plastic bottles (PET / PP material) and plastic labels (PVC / PE film), the friction between the surface of the plastic bottle and the inner wall of the label is relatively large (the coefficient of friction between the two is as high as 0.4-0.6 under dry conditions), which leads to label jamming, label deformation, or even damage.

[0004] To address this, most existing labeling machines use methods such as increasing the label circumference and increasing the label taper. However, these methods also increase production costs, reduce production efficiency, increase equipment size, and limit applicable bottle types. Although they can reduce the defect rate of labeling, they still cannot completely solve the problems of jamming and deformation caused by high friction.

[0005] In addition, existing technologies also include applying silicone oil to the bottle to reduce friction, which not only increases costs but also contaminates the bottle.

[0006] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0007] The purpose of this utility model embodiment is to address the shortcomings of the existing technology structure by proposing a bottle pretreatment device for a labeling machine. By spraying the bottle before the labeling machine, a micron-level water film is formed on the bottle, which greatly reduces the friction between the bottle and the label and solves the above-mentioned problems.

[0008] To achieve the above-mentioned utility model objectives, the bottle pretreatment device for a labeling machine proposed in this utility model embodiment is implemented through the following technical solution: A bottle pretreatment device for a labeling machine includes a conveyor belt that can be connected to the labeling machine. The device is characterized in that: the pretreatment device further includes a humidification chamber and an alignment mechanism; the humidification chamber is fixedly installed and fitted outside the conveyor belt, with slits on its lower front and rear sides for the conveyor belt to pass through; the slits have inlets / outlets that conform to the shape of the bottles and allow bottles on the conveyor belt to enter and exit; the humidification chamber contains ultrasonic nozzles; the nozzles are connected to a water supply system via pipelines; the alignment mechanism is located on the conveyor belt upstream of the humidification chamber and is used to constrain the bottle conveying path.

[0009] The humidifier box is equipped with a drain hole at the bottom.

[0010] The humidifier box is made of stainless steel.

[0011] The ultrasonic nozzles are multiple, and the jet direction is set towards the center of the humidification box.

[0012] The pipeline is equipped with a solenoid valve that is connected and controlled by a controller.

[0013] The humidifier box is equipped with a negative pressure exhaust vent at the top.

[0014] The inner wall of the humidification box is coated with a hydrophobic coating.

[0015] The alignment mechanism is a funnel-shaped guide rod.

[0016] This invention sprays water onto the bottle before the labeling machine, forming a continuous, micron-sized water film on the bottle surface. This transforms dry friction into liquid lubrication, significantly reducing the coefficient of friction. Compared to existing technologies, the advantages of this invention are: To avoid the jamming caused by friction in traditional labeling machines, which often occurs and prolongs the labeling process even if the labeling is eventually completed, requiring adjustments to the bottle spacing to maintain a normal operating cycle, this application shortens the bottle spacing and improves production efficiency.

[0017] The water film can buffer shear stress and reduce the label edge breakage rate. On the other hand, some labels with a high breakage rate due to their thinness cannot be used in conventional labeling machines. After adopting this solution, they can be labeled normally, which increases the range of products that can be selected and also reduces the production cost.

[0018] This avoids the accelerated wear of the labeling cone caused by labeling jamming in existing technologies, and extends the wear cycle of the labeling cone. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The terms "front," "rear," "left," "right," "inner," and "outer" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0023] In the description of the following embodiments, unless otherwise expressly specified and limited, the term "connection" and other such terms should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See Figure 1-3 As shown, this utility model embodiment proposes a bottle pretreatment device for a labeling machine, comprising: Conveyor Belt 1 Conveyor belt 1 can be connected to a labeling machine for conveying plastic bottles.

[0025] Humidifier Box 2 The humidifier box 2 is a fixed stainless steel box fitted over the conveyor belt 1. Slits 21 are provided at the bottom of both the front and rear sides for the conveyor belt to pass through. Above the slits 21 are inlets 22 and outlets 23 for the bottles on the conveyor belt to enter and exit. Flexible curtains are suspended from the inlets 22 and outlets 23 to reduce water vapor leakage from the humidifier box 2 and to prevent water mist from being sprayed outside the box.

[0026] The humidification chamber 2 is equipped with multiple ultrasonic nozzles 24, with their jet direction oriented towards the center of the humidification chamber 2. The nozzles 24 are connected to the water supply system via pipes 4 to spray water mist to moisten the bottle. A solenoid valve 41, controlled by a controller, is installed on pipe 4.

[0027] To handle the water in the housing 2, a drain hole 25 is provided at the bottom of the housing 2, a negative pressure exhaust port 26 is provided at the top of the housing, and the inner wall of the housing 2 is coated with a hydrophobic coating.

[0028] Train alignment mechanism 3 The alignment mechanism 3 is located on the conveyor belt 2 upstream of the humidification box 2. It is used to constrain the conveying path of the bottle so that the bottle can smoothly pass through the inlet 22 along the conveyor belt and enter the humidification box 2.

[0029] The aligning mechanism 3 is a conventional aligning device. In this embodiment, a funnel-shaped guide rod is selected and installed on the conveyor belt 1. The guide rod constrains the bottle body to move towards the center of the conveyor belt, so that it can smoothly pass through the inlet 22 and enter the humidification box 2 along the conveyor belt. Through the above method, the ultrasonic nozzle forms a micron-sized water film on the bottle surface. The water fills the microscopic depressions on the bottle surface. The continuous liquid film formed between the bottle and the label transforms the original direct contact between the "solid surface of the bottle" and the "solid surface of the label" into an indirect contact between "solid-liquid-solid". That is, by replacing "solid dry friction" with "liquid lubrication", the friction can be greatly reduced.

[0030] This invention sprays water onto the bottle before the labeling machine, forming a continuous, micron-sized water film on the bottle surface. This transforms dry friction into liquid lubrication, significantly reducing the coefficient of friction. Compared to existing technologies, the advantages of this invention are: To avoid the jamming caused by friction in traditional labeling machines, which often occurs and prolongs the labeling process even if the labeling is eventually completed, this application addresses the issue by shortening the bottle spacing to maintain a normal operating cycle.

[0031] The water film can buffer shear stress and reduce the label edge breakage rate. On the other hand, some labels with a high breakage rate due to their thinness cannot be used in conventional labeling machines. After adopting this solution, they can be labeled normally, which increases the range of products that can be selected and also reduces the production cost.

[0032] This avoids the accelerated wear of the labeling cone caused by labeling jamming in existing technologies, and extends the wear cycle of the labeling cone.
